- Emerging photovoltaics (PVs) focus on a variety of applications complementing large scale electricity generation. Organic, dye-sensitized, and some perovskite solar cells are considered in building integration, greenhouses, wearable, and indoor applications, thereby motivating research on flexible, transparent, semitransparent, and multi-junction PVs. Nevertheless, it can be very time consuming to find or develop an up-to-date overview of the state-of-the-art performance for these systems and applications. Two important resources for recording research cells efficiencies are the National Renewable Energy Laboratory chart and the efficiency tables compiled biannually by Martin Green and colleagues. Both publications provide an effective coverage over the established technologies, bridging research and industry. An alternative approach is proposed here summarizing the best reports in the diverse research subjects for emerging PVs. Best performance parameters are provided as a function of the photovoltaic bandgap energy for each technology and application, and are put into perspective using, e.g., the Shockley–Queisser limit. In all cases, the reported data correspond to published and/or properly described certified results, with enough details provided for prospective data reproduction. Additionally, the stability test energy yield is included as an analysis parameter among state-of-the-art emerging PVs.

- OBJECTIVES: To determine the health status of athletes before the start of an international athletics championship and to determine whether preparticipation risk factors predicted in-championship injuries.METHODS: At the beginning of the 2013 International Association of Athletics Federations (IAAF) World Championships, all registered athletes (n=1784) were invited to complete a preparticipation health questionnaire (PHQ) on health status during the month preceding the championships. New injuries that occurred at the championships were prospectively recorded.RESULTS: The PHQ was completed by 698 (39%) athletes; 204 (29.2%) reported an injury complaint during the month before the championships. The most common mode of onset of preparticipation injury complaints was gradual (43.6%). Forty-nine athletes in the study reported at least one injury during the championships. Athletes who reported a preparticipation injury complaint were at twofold increased risk for an in-championship injury (OR=2.09; 95% CI 1.16 to 3.77); p=0.014). Those who reported a preparticipation gradual-onset injury complaint were at an almost fourfold increased risk for an in-championship time-loss injury (OR=3.92; 95% CI 1.69 to 9.08); p=0.001). Importantly, the preparticipation injury complaint severity score was associated with the risk of sustaining an in-championship injury (OR=1.14; 95% CI 1.06 to 1.22); p=0.001).SUMMARY AND CONCLUSIONS: About one-third of the athletes participating in the study reported an injury complaint during the month before the championships, which represented a risk factor for sustaining an injury during the championship. This study emphasises the importance of the PHQ as a screening tool to identify athletes at risk of injuries before international championships.

- ObjectivesTo investigate champion long-distance runners’ strategies for managing injury and illness symptoms and staying well.DesignQualitative research study.MethodsTwelve long-distance runners were interviewed immediately after having competed in World Championships finals. Thematic analysis was used to categorise and structure the data. The results were presented as primary themes and overarching constructs representing connections between the primary themes.ResultsThe champion runners’ basic tactic to manage symptoms of ill health was characterized by rapid adjustment of sports load and a strong incentive to learn from experience and professional advice. This tactic was named here educated flexibility. A secondary exigency tactic was associated with reaching short-term goals and a consequential acceptance of health hazards. The runners used economic and other environmental strain to explain use of the exigency tactic. Most champion runners’ long-term strategy to stay well included both tactics successfully combined to maintain a performance level assuring a regular income. Avoidance of letting environmental strain and health problems create vicious circles was at the centre of these strategies.ConclusionsChampion runners’ main strategy to stay well and sustain their superiority in performance was characterized by constantly paying attention to symptoms of ill health, listening to medical advice, and not letting environmental strain interfere with adjustment of sports load. Many top-level runners originate from global regions where formal education programs and health insurance plans are poorly regulated and supported. Bio-psychosocial models including empowerment at individual and systems levels should be considered when health services are planned for professional runners.

Lifetime Prevalence of Verbal, Physical, and Sexual Abuses in Young Elite Athletics Athletes
- 2021
-
Ingår i: Frontiers in Sports and Active Living. - : Frontiers Media SA. - 2624-9367. ; 3
-
Tidskriftsartikel (refereegranskat)abstract
- To examine prevalence of verbal, physical, and sexual abuses in young elite athletes, a cross sectional questionnaire-based survey was conducted during the World Athletics under 20 World Championships. This questionnaire aimed at distinguishing between abuses perpetrated in the context of Athletics from those which were unrelated to Athletics. Four hundred and eighty athletes (52.3%, male) from North America, South America, Europe, Africa, Asia, and Oceania took part in the electronic anonymous survey. Outside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and sexual abuses. However, 45 males (18% of the male population) and 34 females (15% of the female population) athletes reported sexual abuse. Asian athletes reported a slightly higher rate of sexual abuse; three quarters of them being non-touching abuses. Inside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and non-touching sexual abuses. However, 58 males (23%) and 47 females (21%) reported verbal abuses. Thirty-one males (12%) and 20 females (9%) reported physical abuses, whereas 30 males (12%) and 17 females (7%) reported sexual abuses. Physical abuses were slightly more frequent in Asia and in Africa and less frequent in South America. Sexual abuses inside Athletics also differed over regions, and were unexpectedly twice more frequent than expected in Asia and slightly less frequent than expected in Europe. Friends and partners were identified as the more frequent (> 50%) abusers outside or inside the Athletics settings, whereas outside Athletics and inside Athletics, coaches were identified as sexual abuse perpetrators in 8 and 25% of cases, respectively. The prevalence of verbal, physical, or sexual abuses is high but consistent with what has been reported in United Kingdom, Norway, Canada, and Sweden at national level in recreational or elite athletes. Sexual abuse, including touching or penetrative abuses, occurred significantly more often in male athletes when compared to female athletes. This finding invites healthcare and social workers, and policymakers to also consider the risk of sexual abuse of young male athletes in Athletics. These results also call for longitudinal studies on young elite athletes.

The Europeanization of Swedish Alcohol Policy
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this dissertation is to study the Europeanization of Swedish alcohol policy from 1995-2006. It analyses the development of Swedish and European alcohol policy and answers the following research questions: How has alcohol policy developed on the national and the EU level during this period? What are the Swedish alcohol policy initiatives on the EU level? What does the interplay between Swedish and European policy processes look like? Of interest for this dissertation is also how the Swedish view on alcohol policy has been received on EU level.The dissertation comprises four related articles and an introductory chapter. In the articles official documents and interviews are analyzed in the context of the literature on Europeanization, using the concepts framing, narrative and new modes of governance. Article I explores the history of negotiations between Sweden and the EU on the traveller’s allowances question. Article II and III analyse how Swedish authorities, first through research and later through formal policy-making during the Swedish Presidency, tried to reframe alcohol on the EU-level. Finally, the fourth article is a comparative analysis of the Nordic retail monopolies, analyzing how the monopolies have developed and reacted to national and international pressures on their activities.The dissertation shows that Swedish authorities have influenced the EU level by putting alcohol on the agenda, and offered pressure and economic support to make sure that alcohol as a public health question has become and been kept as a prioritized question. This development is, however, nested inside the changing scope and emphasis of the EU. The emergence of a European alcohol policy as a public health-oriented process has been made possible through a new focus on the EU level, with increased cooperation between member states and a trend toward harmonization of policy and frames when it comes to alcohol.

- Background Athletes competing in athletics (track and field) at international level may be participating with underlying undiagnosed life-threatening cardiovascular conditions. Our objective was to analyse variations in pre-participation cardiac evaluation prevalence among athletes participating in two International Association of Athletics Federations (IAAF) World Athletics Championships, with regard to the human developmental level and global region of their home countries, as well as athletes’ age category, gender, event group and medical insurance type.Design Cross-sectional web-based survey.MethodsA total of 1785 athletes competing in the IAAF World Under 18 Championships Nairobi 2017 and World Championships London 2017 were invited to complete a pre-participation health questionnaire investigating the experience of a pre-participation cardiac examination.Results A total of 704 (39%) of the athletes participated. Among these, 59% (60% of women; 58% of men) reported that they had been provided at least one type of pre-participation cardiac evaluation. Athletes from very high income countries, Europe and Asia, showed a higher prevalence of at least one pre-participation cardiac evaluation.Conclusions The prevalence of pre-participation cardiac evaluation in low to middle income countries, and the African continent in particular, needs urgent attention. Furthermore, increases in evaluation prevalence should be accompanied by the development of cost-effective methods that can be adopted in all global regions.

Tidskriftsartikel (refereegranskat)abstract
- The organization of sports at the national level has seldom been included in scientific discussions of sports injury prevention. The aim of this study was to develop a model for organization of sports that supports prevention of overuse injuries. The quality function deployment technique was applied in seminars over a two-season period to develop a national organizational structure for athletics in Sweden that facilitates prevention of overuse injuries. Three central features of the resulting model for organization of sports at the national level are (a) diminishment of the organizational hierarchy: participatory safety policy design is introduced through annual meetings where actors from different sectors of the sporting community discuss training, injury prevention, and sports safety policy; (b) introduction of a safety surveillance system: a ubiquitous system for routine collection of injury and illness data; and (c) an open forum for discussion of safety issues: maintenance of a safety forum for participants from different sectors of the sport. A nonhierarchical model for organization of sports at the national level - facilitated by modern information technology - adapted for the prevention of overuse injuries has been developed. Further research is warranted to evaluate the new organizational model in prospective effectiveness studies.

- Enabling athletes to achieve peak performances while also maintaining high levels of health is contextually complex. We aim to describe what a health system is and apply the essential functions of stewardship, financing, provision of services and resource generation to an Australian high-performance sport context. We introduce a fifth function that health systems should not detract from athletes ability to achieve their sports goals. We describe how these functions aim to achieve four overall outcomes of safeguarding the health of the athletes, responding to expectations, providing financial and social protection against the costs of ill health, and efficient use of resources. Lastly, we conclude with key challenges and potential solutions for developing an integrated health system within the overall performance system in high-performance sport.

Tidskriftsartikel (refereegranskat)abstract
- ObjectiveDuring international athletics championships, the incidence and characteristics of new injuries have been well described: about 10% of registered athletes have a new injury. It seemed also important to understand the complaints of athletes in terms of injuries in the period before and at the start of the championships and potential association with potential new injuries for identification of possible risk factors.The objective of this study was to determine the health of athletes before the start of an international athletics championship and to identify risk factors for new injuries.Patients and methodsIn the 2013 World Athletics Championships in Moscow, all athletes enrolled (n = 1784) were asked to complete a pre-participation health questionnaire (PHQ) collecting data on the health status during the months preceding the championships. During the period of the Championships, all new injuries were prospectively recorded.ResultsThe PHQ was completed by 698 (39%) of the athletes; 204 (29.2%) reported suffering such injury complaint during the month before the championships. The most common mode of onset of pain before championships was gradual (43.6%). Forty-nine athletes reported at least one new injury during the championships. Athletes who reported suffering injuries before championships had an increased risk of having a new injury during the championship [odds ratio (OR) = 2.09; 95% confidence interval (95% CI): 1.16–3.77; P = 0.014] and those who reported suffering injuries championships before a gradual fashion appearance were at increased risk of almost four times to re-injury with sport stop in the championship (OR = 3.92; 95% CI: 1.69–9.08; P = 0.001).Discussion/ConclusionApproximately one third of athletes participating in an international athletics championship and involved in this study reported an injury complaint during the month before the championships. This represented a risk factor to suffer a new injury during the championship.This study highlights the potential importance of a pre-participation health questionnaire as a screening tool to identify athletes at risk of injury before international athletics championships.

- Objectives: To explore the performance of retrospective health data collected from athletes before Athletics championships for the analysis of risk factors for in-competition injury and illness (IandI). Methods: For the 2013 European Athletics Indoor Championships, a self-report questionnaire (PHQ) was developed to record the health status of 127 athletes during the 4 weeks prior to the championship. Physician-based surveillance of in-competition IandI among all 577 athletes registered to compete was pursued during the championships. Results: 74 athletes (58.3%) from the sample submitted a complete PHQ, 21 (28%) of these athletes sustained at least one injury and/or illness during the championships. Training more than 12 h/week predisposed for sustaining an in-competition injury, and a recent health problem for in-competition illness. Among the 577 registered athletes, 60 injuries (104/1000 registered athletes) were reported. 31% of injuries were caused by the track, and 29% by overuse. 29 illnesses were reported (50/1000 registered athletes); upper respiratory tract infection and gastro-enteritis/diarrhoea were the most reported diagnoses. Conclusions: Pre-participation screening using athletes self-report PHQ showed promising results with regard to identification of individuals at risk. Indoor injury types could be attributed to extrinsic factors, such as small track size, track inclination, and race tactics. (C) 2014 Elsevier Ltd. All rights reserved.

- Objectives: The aim was to describe the annual incidence and types of musculoskeletal injuries, and to examine factors associated with injury risk. Design: A 52-week prospective study in Swedish youth athletics aged 12-15 years. Methods: Data on exposure to training and injury were collected from parents/caregivers and youth athletes using a web-survey system. Results: A total of 101 (86%) youth athletes participated. Fifty-four (53%) of the athletes reported one new injury. Girls were at higher risk of sustaining an injury than boys (p = 0.048). Ninety-one percent of the new injuries were non-traumatic and 85% occurred in the lower extremities. Injuries to the front thigh represented 20% of the injuries. Cox proportional hazard regression analyses showed a six-fold increased risk for a first injury for athletes reporting use of spikes and training <6 h every two weeks (hazard ratio, 6.1; 95% confidence interval, 1.2-31.3) compared to athletes training <6 h using no spikes. Athletes training 6 h or more reporting use or no use of spikes had an eight-fold increase injury risk (p < 0.01). Conclusions: Almost half of the youth athletes experienced a new injury and girls had a higher risk compared to boys. Nine out of ten injuries were related to overuse. An interesting observation was the high incidence of injuries to the quadriceps muscle complex. The study identified a correlation with training hours and an interaction with track spikes and risk of injury that needs further attention. (c) 2021 The Author(s).

- To evaluate clinical performance of a new automated cell-free (cf)DNA assay in maternal plasma screening for trisomies 21, 18, and 13, and to determine fetal sex.Maternal plasma samples from 1200 singleton pregnancies were analyzed with a new non-sequencing cfDNA method, which is based on imaging and counting specific chromosome targets. Reference outcomes were determined by either cytogenetic testing, of amniotic fluid or chorionic villi, or clinical examination of neonates.The samples examined included 158 fetal aneuploidies. Sensitivity was 100% (112/112) for trisomy 21, 89% (32/36) for trisomy 18, and 100% (10/10) for trisomy 13. The respective specificities were 100%, 99.5%, and 99.9%. There were five first pass failures (0.4%), all in unaffected pregnancies. Sex classification was performed on 979 of the samples and 99.6% (975/979) provided a concordant result.The new automated cfDNA assay has high sensitivity and specificity for trisomies 21, 18, and 13 and accurate classification of fetal sex, while maintaining a low failure rate. The study demonstrated that cfDNA testing can be simplified and automated to reduce cost and thereby enabling wider population-based screening.

An eHealth Application of Self-Reported Sports-Related Injuries and Illnesses in Paralympic Sport : Pilot Feasibility and Usability Study
- 2017
-
Ingår i: JMIR Human Factors. - Toronto, Canada : JMIR Publications. - 2292-9495. ; 4:4

Tidskriftsartikel (refereegranskat)abstract
- Background: Sport participation is associated with a risk of sports-related injuries and illnesses, and Paralympic athletes’ additional medical issues can be a challenge to health care providers and medical staff. However, few prospective studies have assessed sports-related injuries and illnesses in Paralympic sport (SRIIPS) over time. Advances in mobile phone technology and networking systems offer novel opportunities to develop innovative eHealth applications for collection of athletes’ self-reports. Using eHealth applications for collection of self-reported SRIIPS is an unexplored area, and before initiation of full-scale research of SRIIPS, the feasibility and usability of such an approach needs to be ascertained.Objective: The aim of this study was to perform a 4-week pilot study and (1) evaluate the monitoring feasibility and system usability of a novel eHealth application for self-reported SRIIPS and (2) report preliminary data on SRIIPS.Methods: An eHealth application for routine collection of data from athletes was developed and adapted to Paralympic athletes. A 4-week pilot study was performed where Paralympic athletes (n=28) were asked to weekly self-report sport exposure, training load, general well-being, pain, sleep, anxiety, and possible SRIIPS. The data collection was followed by a poststudy use assessment survey. Quantitative data related to the system use (eg, completed self-reports, missing responses, and errors) were analyzed using descriptive statistics. The qualitative feasibility and usability data provided by the athletes were condensed and categorized using thematic analysis methods.Results: The weekly response rate was 95%. The athletes were of the opinion that the eHealth application was usable and feasible but stated that it was not fully adapted to Paralympic athletes and their impairments. For example, it was difficult to understand how a new injury or illness should be identified when the impairment was involved. More survey items related to the impairments were requested, as the athletes perceived that injuries and illnesses often occurred because of the impairment. Options for description of multifactorial incidents including an injury, an illness, and the impairment were also insufficient. Few technical issues were encountered, but athletes with visual impairment reported usability difficulties with the speech synthesizer. An incidence rate of 1.8 injuries and 1.7 illnesses per 100 hours of athlete exposure were recorded. The weekly pain prevalence was 56% and the impairment contributed to 20% of the reported incidents.Conclusions: The novel eHealth-based application for self-reported SRIIPS developed and tested in this pilot study was generally feasible and usable. With some adaptation to accommodate Paralympic athletes’ prerequisites and improved technical support for athletes with visual impairment, this application can be recommended for use in prospective studies of SRIIPS.

- Introduction Sports-related injuries and illnesses in Paralympic sport (SRIIPS) are a concern, but knowledge about the etiology and risk factors is limited. The aim of this study was to describe the annual incidence, type, and severity of injuries and illnesses among Swedish Paralympic athletes and to assess risk factors. Methods Swedish Paralympic athletes (n = 107) self-reported SRIIPS every week during 52 weeks using an eHealth application. Incidence proportions (IP) and incidence rates (IR) were used as measures of disease burden. Time-to-event methods (Kaplan-Meier and Cox regression) were used to identify risk factors. Results The annual IP for injury was 68% and for illness 77%. The injury IR was 6.9/1000 hours and the illness IR 9.3/1000 hours. The median time to injury was 19 weeks (95% CI: 10.5-27.4) and to illness 9 weeks (95% CI: 1.4-16.6). Most injuries occurred during training, and 34% were classified as severe (>= 21 days of time loss). An increased injury risk was observed among athletes in team sports (HR 1.88; 95% CI: 1.19-2.99), athletes with a previous severe injury (HR 2.37; 95% CI: 1.47-3.83), and male athletes (HR 1.76; 95% CI: 1.06-2.93). The most common illness type was infection (84%). Athletes in team sports (HR 1.64; 95% CI: 1.05-2.54) and males with a previous illness (HR = 2.13; 95% CI: 1.04-4.36) had a higher illness risk. Conclusion Paralympic athletes report a high incidence of injuries and illnesses over time. This emphasizes the need to develop preventive strategies of SRIIPS and optimize medical services for this heterogeneous athlete population.

- Our knowledge of sports-related injuries in para-sport is limited and there are no data on how Paralympic athletes themselves perceive an injury. The aim of this qualitative study was to explore Paralympic athletes’ perceptions of their experiences of sports-related injuries, risk factors and preventive possibilities. Eighteen Swedish Paralympic athletes with vision impairment, intellectual impairment, spinal cord injury, cerebral palsy, myelomeningocele, dysplasia and neuromuscular disorder, representing 10 different para-sports, were interviewed. The qualitative phenomenographic method was used to interpret the data. The analysis revealed nine categories of perceptions of experiences. The athletes perceived that their impairments were involved in the cause and consequential chains associated with a sports-related injury. Other categories that denoted and described these injuries were: sport overuse, risk behaviour, functional limitations, psychological stressors, the normalised pain, health hazards, individual possibilities to prevent sports-related injuries and unequal prerequisites. This qualitative study revealed that Paralympic athletes’ perceptions of their experiences of sports-related injuries are complex and multifactorial, and in several ways differ from able-bodied athletes. This needs to be considered in the sports health and safety work within the Paralympic Movement as well as in the design of future injury surveillance systems and preventive programmes.

- BackgroundWith increased participation in Paralympic sports, the burden of sports-related injuries and illnesses may increase. However, there is limited knowledge about the epidemiology of sports-related injuries and illnesses in Paralympic sports (SRIIPS). ObjectiveTo describe among Swedish Paralympic athletes the 1-year retrospective period prevalence of severe SRIIPS and the point prevalence of all SRIIPS and to examine differences in prevalence proportions between athletes with different impairments, behaviors, and sport characteristics. DesignCross-sectional study. SettingSwedish Paralympic Programme. ParticipantsOne hundred and four Paralympic athletes with visual, physical, and intellectual impairment. MethodsAn eHealth application adapted to Paralympic athletes was used to collect self-report data on existing and previous SRIIPS, as well as impairment, behavior, and sport characteristics. Main Outcome MeasurementsOne-year retrospective period prevalence and point prevalence. ResultsThe period prevalence of severe injuries was 31% (95% CI 23-40) and the point prevalence 32% (95% CI 24-41). The period prevalence of severe illnesses was 14% (95% CI 9-23), and 13% of the athletes (95% CI 8-22) reported a current illness. More severe injuries (Pamp;lt;.05) were reported by athletes aged 18 to 25years, not using assistive device, having pain during sport, using analgesics, continuing training injured, and feeling guilt when missing exercise. Athletes who reported a previous severe injury, having pain in daily life and during sport, using analgesics, and being upset when unable to exercise had a higher prevalence of current injuries (Pamp;lt;.05). Being female, reporting previous severe illness, using prescribed medication, and feeling anxious/depressed were features associated with ongoing illnesses (Pamp;lt;.05). ConclusionParalympic athletes report a high prevalence of SRIIPS. Behavioral and psychological aspects as well as pain and use of medication appear to be associated with the occurrence of SRIIPS. The results imply that factors leading to SRIIPS are complex and call for a broad biopsychosocial approach when developing preventive measures. Level of EvidenceIII.

- BAKGRUND: Intresset för parasport har vuxit det senaste årtiondet. Andelen paraidrottare som elitsatsar ökar ochmånga prestationer går att jämföra med idrottare utan funktionsnedsättning. Deltagande i idrott innebär dock en ökadrisk för att drabbas av en idrottsrelaterad skada eller sjukdom (IRSS). IRSS är ett bekymmer inom flertalet idrotter,vilket kan leda till förlorad träningstid samt negativa hälsorelaterade konsekvenser. Få studier har dock undersökt förekomst och etiologi av IRSS inom parasport. För att öka kunskapen om IRSS har vi initierat ”The Sports-Related Injuryand Illness in Paralympic Sports Study” (SRIIPSS) (Fagheret al. 2016).SYFTE: Syftet med denna studie var att: i) retrospektivt undersöka ett-årsprevalensen av svåra (>3 veckors tidsförlustfrån träning) IRSS; ii) beskriva punktprevalensen av IRSSsamt; iii) kartlägga sambanden mellan IRSS och demografiska data.METOD: Sammanlagt 107 svenska paraidrottare, samtligakandidater till Paralympics, är inkluderade i SRIIPSS. Avdessa svarade 104 (97%) elektroniskt på en baslinjeenkät,anpassad till och testad av paraidrottare. Inkluderade variabler var: kön, längd och vikt, idrott, träningsmängd, funktionsnedsättning, hjälpmedel, mediciner, smärta, oro samtIRSS. Data analyserades med deskriptiv statistik (medelvärde, SD, prevalens, CI). Chi2-test av homogenitet användesför att jämföra frekvensfördelningar mellan variablerna.RESULTAT: 31 % (CI 23-40) av idrottarna rapporterade ensvår idrottsskada under det senaste året. Utav dessa var 78 %relaterade till överbelastning. Sommaridrotter, goalball ochrullstolsbasket samt idrottare med dysmeli och amputationhade en högre prevalens. Signifikanta samband (p<0.05)fanns mellan svår skada och smärta under träning, styrketräning utöver idrottsspecifik träning, att inte använda hjälpmedel samt användning av antiinflammatoriska läkemedeloch paracetamol. 14 % (CI 9-23) rapporterade en svår sjukdom och idrottare inom paracykling och parasimning samtuthållighetsidrottare hade den högsta prevalensen. Signifikanta samband (p<0.05) fanns mellan svår sjukdom ochålder < 30 år. Punktprevalensen av skada var 32 % (CI (24-41) och 94 % av skadorna var relaterade till överbelysning.Idrottare inom sommaridrotter, lagidrotter samt explosivaidrotter hade en högre prevalens. Signifikanta samband(0<0.05) fanns mellan skada och smärta i det dagliga livetsamt under träning. Punktprevalensen av sjukdom var 14 %CI (8-22); signifikanta samband (p<0,05) fanns mellansjukdom och kvinnor, oro samt receptbelagd medicin.KONKLUSION: En tredjedel av alla svenska paraidrottaredrabbades under ett år av en svår idrottsskada och 14% aven svår sjukdom. Fortsatta prospektiva studier kommer attkunna identifiera riskfaktorer, orsakssamband samt på siktta fram förebyggande strategier.

- BACKGROUND:Paralympic sport provides sporting opportunities for athletes with a disability, with the Paralympic Games as the main event. Participation in sport is, however, associated with a significant risk for sustaining injuries and illnesses. Our knowledge of sports-related injuries and illnesses in Paralympic sport is very limited and there are no large-scale epidemiological cohort studies. The purpose here is to present a protocol for a prospective longitudinal study: The Sports-Related Injuries and Illnesses in Paralympic Sport Study (SRIIPSS).METHODS/DESIGN:An argument-based method for investigation of design problems was used to structure the study protocol. The primary requirement of the protocol is to allow prospective studies over time and include exposure to both training and competition. To reflect the complexity of Paralympic sport with athletes' pre-existing impairments, use of assistive equipment, pain and other and medical issues, it is required that the data collection system is specifically adapted to Paralympic sport. To allow the collection of data, at the same time as there is limited access to coaches and medical personnel, it is advantageous that data can be collected online directly from the athletes. Based on this a self-report athlete monitoring system will be developed, where the athletes can enter data weekly via their mobile phones or lap-tops. Data will be collected from around 100 Swedish Paralympic athletes for approximately 1 year, which will allow us to i) prospectively estimate the annual incidence of sports-related injuries and illnesses and ii) explore risk factors and mechanisms for sustaining sports-related injuries and illnesses based on athlete exposure and training loads.DISCUSSION:For effective implementation of injury and illness prevention measures, comprehensive epidemiological knowledge is required. This study will be the first prospective longitudinal self-report study of sports-related injuries and illnesses in Paralympic sport over a longer period of time. The results will eventually contribute to the development of evidence-based preventive measures specifically adapted to Paralympic sport in order to provide safe and healthy sport participation. Thereby, the project will be of relevance for Paralympic athletes at all levels and to the Paralympic Movement.

- A method to enhance the multivariate data interpretation of, for instance, metabolic profiles is presented. This was done by correlation scaling of 1H NMR data by the time pattern of drug metabolite peaks identified by LC/MS, followed by parallel factor analysis (PARAFAC). The variables responsible for the discrimination between the dosed and control rats in this model were then eliminated in both data sets. Next, an additional PARAFAC analysis was performed with both LC/MS and 1H NMR data, fused by outer product analysis (OPA), to obtain sufficient class separation. The loadings from this second PARAFAC analysis showed new peaks discriminating between the classes. The time trajectories of these peaks did not agree with the drug metabolites and were detected as possible candidates for markers. These data analyses were also compared with the PARAFAC analysis of raw data, which showed very much the same loading peaks as for the correlation-scaled data, although the intensities differed. Elimination of the variables correlated with the drug metabolites was therefore necessary to be able to select the peaks which were not drug metabolites and which discriminated between the classes.1

- In the analyses of highly complex samples (for example, metabolic fingerprinting), the data might not suffice for classification when using only a single analytical technique. Hence, the use of two complementary techniques, e.g., LUMS and H-1-NMR, might be advantageous. Another possible advantage from using two different techniques is the ability to verify the results (for instance, by verifying a time trend of a metabolic pattern). In this work, both LC/MS and H-1-NMR data from analysis of rat urine have been used to obtain metabolic fingerprints. A comparison of three different methods for data fusion of the two data sets was performed and the possibilities and difficulties associated with data fusion were discussed. When comparing concatenated data, full hierarchical modeling, and batch modeling, the first two approaches were found to be the most successful. Different types of block scaling and variable scaling were evaluated and the optimal scaling for each case was found by cross validation. Validations of the final models were performed by means of an external test set.(2)

Processing and analysis of NMR data : Impurity determination and metabolic profiling
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes the use of nuclear magnetic resonance (NMR) spectrometry as an analytical tool. The theory of NMR spectroscopy in general and quantitative NMR spectrometry (qNMR) in particular is described and the instrumental properties and parameter setups for qNMR measurements are discussed. Examples of qNMR are presented by impurity determination of pharmaceutical compounds and analysis of urine samples from rats fed with either water or a drug (metabolic profiling). The instrumental parameter setup of qNMR and traditional data pre-treatments are examined. Spectral smoothing by convolution with a triangular function, which is an unusual application in this context, was shown to be successful regarding the sensitivity and robustness of the method in paper II. In addition, papers III and IV comprise the field of peak alignment, especially designed for 1H-NMR spectra of urine samples. This is an important preprocessing tool when multivariate analysis is to be applied. A novel peak alignment method was developed and compared to the traditional bucketing approach and a conceptually different alignment method.Univariate, multivariate, linear and nonlinear data analyses were applied to qNMR data. In papers I–II, calibration models were created to examine the potential of qNMR for these applications. The data analysis in papers III–VI was mainly explorative. The potential of data fusion and data correlation was examined in order to increase the possibilities of analysing the highly complex samples from metabolic profiling (papers V–VI). Data from LC/MS analysis of the same samples were used with the 1H-NMR data in different ways. Correlation analyses between the 1H-NMR data and the drug metabolites identified from the LC/MS data were also performed. In this process, data fusion proved to be a valuable tool.

- Objectives: To investigate health-related factors associated with self-rated race performance outcomes among recreational long-distance runners. Design: Panel study. Methods: Data were collected from runners one month before and after a community-level race event including distances from 8 to 42.2 km. The primary outcome measure was self-rated race performance outcome. The explanatory variables represented health complaints suffered during the build-up year, the pre-race month, and the race and among full marathon runners predicted objective performance outcome (mean pace equal to training pace or faster). Multiple logistic regression was used to determine factors associated with the self-rated performance outcome. Results: Two-hundred forty-five runners (29%) provided complete data sets. Seventy-four percent of the runners reached their desired race performance outcome. Achievement of the performance outcome was more likely when having avoided illness during the build-up and pre-race periods (OR = 3.8; 95% CI:1.8-8.0, p amp;lt; 0.001), having avoided per-race injury (OR=3.0; 95% CI:1.2-7.4, p = 0.02) and avoided perrace illness (OR= 4.1; 95% CI:1.3-15, p = 0.020). Having obtained the self-rated performance outcome was also associated with running a shorter distance (OR=3.6; 95% CI: 1.7-8.0,p = 0.001) and being younger than 50 years of age (OR= 2.4; 95% CI:1.1-5.3-8.3, p = 0.03). Having met the predicted objective performance outcome predisposed marathon runners to also obtain the self-rated performance outcome (OR= 4.7, 95% CI: 1.5-16, p amp;lt; 0.01). Conclusions: Having avoided illness during build-up and pre-race was positively associated with self-rated race performance outcome among recreational runners. Adjusting the desired performance outcomes with regard to recent illness and age may help recreational runners to more often achieve their goals and thereby prevent them from leaving the sport.

- Objectives: The aim was to describe levels of subjective Health Literacy (HL), and to examine possible differences in prevalence proportions between sexes, age groups and level of educations among youth athletes and their mentors (coaches, parents/caregivers) in Swedish Athletics. Design: Cross-sectional. Methods: Data on subjective HL were collected using the Swedish Communicative and Critical Health Literacy (S-CCHL) instrument for mentors and for youth the School-Aged Children (HLSAC) instrument. Questions assessing mentors literacy on sports injury and return to play were also included. Results: The surveys were completed by 159 (91%) mentors and 143 youth athletes (87%). The level of S-CCHL was sufficient in 53% of the mentors. Of youth athletes, 28% reported a high level of HL and the item with least perceived high HL (21%) was critical thinking. Ninety-four percent of the mentors believed that it is quite possible to prevent injuries in athletics and 53% perceived having a very good knowledge about how to prevent injuries. Forty-six percent of the mentors perceived having a very good knowledge of return to sport criteria. Conclusions: The level of health literacy was low with about half of the mentors and one out of three youth athletes having adequate HL levels. Only half of the mentors stated having a good knowledge of various injury prevention strategies. To reduce health consequences in youth sport and enable talent development more work is needed to understand the facilitators and barriers for the uptake of various health promotion and injury prevention strategies.

Tidskriftsartikel (refereegranskat)abstract
- It is today recognized that a large share of manifestations of ill health associated with sports participation is preventable and that a focus should be on implementation of effective prevention programs. One hindrance for implementation of effective preventive measures in sports medicine may be that an update of preventive frameworks to the current health challenges has not been performed. We introduce classifications of prevention that are adjusted to the health challenges faced by sports participants in the present day. To enable more precise characterizations of preventive measures, we find it necessary to describe them in two dimensions. In one dimension, pathological developments in the body are used as a basis for classification of preventive measures, while the other dimension classifies prevention on the grounds of epidemiological risk indicators. We conclude that longitudinal research combining diagnostic procedures, surveillance, and targeted interventions is needed to enable the introduction of prevention programs for athletes in the beginning of their sporting career at the pre-diagnostic stage, as well as suitable prevention measures for the adult elite athletes. A more distinct classification of prevention supports a specific and cost-effective planning and translation of sports injury prevention and safety promotion adjusted to the delivery settings, various injury types, and different groups of athletes. The present classifications constitute an additional conceptual foundation for such efforts.

- Background Epidemiological studies have mainly been performed on team sports. The authors set out to develop a protocol for large-scale epidemiological studies of injuries among elite athletics athletes. Methods An argument-based method for investigation of complex design problems was used to structure the collection and analysis of data. Specification of the protocol was preceded by an examination of requirements on injury surveillance in individual sports and iterated drafting of protocol specifications, and followed by formative evaluations. Results The requirements analysis shows that the central demand on the protocol is to allow for detailed epidemiological analyses of overuse injuries, which subsequently requires regular collection of self-reported data from athletes. The resulting study protocol is centred on a web-based weekly athlete e-diary enabling continual collection of individual-level data on exposure and injuries. To be able to interpret the self-reported data on injury events, collection of a wide range of personal baseline data from the athlete, including a psychological profile, is included in the protocol. Conclusions The resulting protocol can be employed in intervention programmes that can prevent suffering among both adult elite and youth talent athletes who have made considerable life investments in their sport.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to develop athletics health guidance (AHG) aimed at supporting coaches and parents involved in organized child athletics by providing practical advice and tools for the management of the most common health problems experienced in athletics by the 12- to 15-year olds. The study used participatory action research (PAR) and an established health service guideline development procedure modified to fit AHG development in child athletics. A sequential process consisting of four steps with associated subgoals was employed. The collected data were structured according to the AHG development steps and analyzed using qualitative methods. The most common health concern identified was injuries related to growth and overuse. No randomized controlled studies investigating injury prevention programs or any existing concepts/guidelines in child athletics were found that could be used in the development of the AHG. A requirements document was instead defined in a nominal group process and used for the AHG development. The areas included in the final AHG were as follows: training youth athletes, growth and puberty, recovery, injury prevention, injuries and illnesses, mental illness, safe sport, and anti-doping. The evidence regarding health issues in child athletics is limited, indicating that actions to support good health in the sport are currently based essentially on best practice. The long-term aim of the AHG and associated website is to systematically create and introduce conditions that can bridge the "know-do gap" and provide coaches and parents with easy-to-access and up-to-date knowledge in the field of child athlete health in athletics.

- Engaging in competitive sports as a youth can have many health benefits, but recent studies also report a high risk for injury. The long-term purpose of this Swedish research program is to develop a framework for safe track and field training for young athletes (aged 12-15years). The aim of this study was to establish what is perceived to contribute and cause injuries in youth track and field by compiling the best available experiential knowledge about the underlying factors and use this knowledge to identify appropriate areas to handle these in practical ways. Nine focus group interviews with in total 74 participants and confirming interviews with five individuals were performed in seven Swedish regions. Qualitative research methods were used for data analysis. Injuries in youth athletes were not considered to be strictly the result of individual factors but rather the result of the interactions between factors at different levels. Three major factors emerged as follows: Insufficient knowledge for athletic development in daily practice; shortsighted communities of practice and sports policies not adjusted to youth; and societal health behaviors. The experiential knowledge in the national sporting community suggests that if effective and sustainable injury prevention processes are to be implemented for youth track and field, an ecological (holistic-developmental) approach to injury prevention is needed. Such an approach allows a longitudinal development-focused strategy for prevention that spans an athletes entire career.

- Objective To estimate the incidence, type and severity of musculoskeletal injuries in youth and adult elite athletics athletes and to explore risk factors for sustaining injuries. Design Prospective cohort study conducted during a 52-week period. Setting Male and female youth and adult athletics athletes ranked in the top 10 in Sweden (n=292). Results 199 (68%) athletes reported an injury during the study season. Ninety-six per cent of the reported injuries were non-traumatic (associated with overuse). Most injuries (51%) were severe, causing a period of absence from normal training exceeding 3 weeks. Log-rank tests revealed risk differences with regard to athlete category (p=0.046), recent previous injury (>3 weeks time-loss; p=0.039) and training load rank index (TLRI; p=0.019). Cox proportional hazards regression analyses showed that athletes in the third (HR 1.79; 95% CI 1.54 to 2.78) and fourth TLRI quartiles (HR 1.79; 95% CI 1.16 to 2.74) had almost a twofold increased risk of injury compared with their peers in the first quartile and interaction effects between athlete category and previous injury; youth male athletes with a previous serious injury had more than a fourfold increased risk of injury (HR=4.39; 95% CI 2.20 to 8.77) compared with youth females with no previous injury. Conclusions The injury incidence among both youth and adult elite athletics athletes is high. A training load index combing hours and intensity and a history of severe injury the previous year were predictors for injury. Further studies on measures to quantify training content and protocols for safe return to athletics are warranted.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To examine the risk indicators associated with sustaining musculoskeletal injuries in youth and adult elite athletics athletes competing at national and international levels.Design: Prospective cohort study conducted during a 52-week period starting in March 2009. A web-based athlete electronic diary was administrated every week by email to athletes for self-reporting of data on training, competition and injuries.Setting: Male and female youth and adult athletics athletes ranked in the top 10 in Sweden (n=292).Results: One-hundred ninety-nine (68%) athletes reported an injury during the study season. The median time to first injury was 101 days (95% confidence interval (CI) 75–127). Univariate log-rank tests revealed risk differences with regard to athlete category (P=0.046), serious injury (>3 weeks time loss) during the previous season (P=0.039) and training load rank index (TLRI) (P=0.019). Multivariate Cox proportional hazards regression analyses showed that athletes in the third (hazard ratio (HR) 1.79; 95% CI 1.54–2.78) and fourth TLRI quartile (HR 1.79; 95% CI 1.16–2.74) had almost a twofold increased risk of injury compared with their peers in the first quartile and interaction effects between athlete category and previous injury; youth male athletes with a previous serious injury had more than a fourfold increased risk of injury (HR=4.39; 95% CI 2.20–8.77) compared with youth females with no previous injury.Conclusions: A training load index combing hours and intensity and a history of severe injury the previous year are predictors for injury risk among elite athletic athletes. Future studies on measures to quantify training content and protocols for safe return to athletics are warranted.

The diagnosis group displaying the highest injury prevalence was inflammation and pain in the gradual onset category (1-year prevalence, 20.9%; 95% CI, 16.2%-26.2%; and point prevalence, 23.2%; 95% CI, 18.4%-28.7%). A strong tendency for higher 1-year prevalence of 16.5% (95% CI, 12.2%-21.4%) than point prevalence of 8.5% (95% CI, 5.5%-12.5%) was recorded for sudden onset injuries in the diagnosis group sprain, strain, and rupture. The body region showing the highest injury prevalence was the knee and lower leg with 15.0% (95% CI, 11.0%-19.8%) 1-year prevalence and 13.7% (95% CI, 9.8%-18.3%) point prevalence, followed by the Achilles tendon, ankle, and foot/toe with 11.7% (95% CI, 8.2%-16.1%) 1-year prevalence and 11.4% (95% CI, 7.9%-15.8%) point prevalence. less thanbrgreater than less thanbrgreater thanConclusion: The injury prevalence is high among Swedish elite track and field athletes. Most of the injuries affect the lower extremities and are associated with a gradual onset. Although it is associated with a potential recall bias, the 1-year retrospective prevalence measure captured more sudden onset injuries than the point prevalence measure. Future prospective studies in track and field are needed to identify groups of athletes at increased risk.

Towards systematic prevention of athletics injuries : Use of clinical epidemiology for evidence-based injury prevention
- 2012

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aims of this thesis were to outline the design protocol for a prospective clinical epidemiological study of injuries among athletics athletes; study the 1-year prevalence, the point prevalence and incidence of injuries in total cohorts of Swedish elite adult and talented youth athletics athletes; pinpoint the risk indicators and factors for different injury types/patterns in athletics.In paper I, an argument-based method to investigate complex design problems was used to structure the collection and analysis of data. A requirement analysis showed that a central requirement of an injury surveillance protocol for elite athletics should allow for detailed epidemiological analyses of overuse injuries, requiring self-reported data from athletes. The resulting study protocol was centred on a web-based weekly athlete e-diary enabling continuous collection of individual-level data on exposure and injuries.In paper II, the prevalence of injuries was examined and 278 athletes (87%) of the enrolled study population submitted their assessments via the web survey. The overall 1-year retrospective injury prevalence was 42.8% (95% CI 36.9–49.0%). The point prevalence of ongoing injury was 35.4% (95% CI 29.7–41.4%). The 1-year injury prevalence showed a tendency to vary with regard to gender and age (p = 0.11). The diagnostic group that displayed the highest 1-year prevalence (20.9%, 95% CI 16.2–22.2%) and point prevalence (23.2%, 95% CI 18.4–28.7%) of injury was inflammation and pain with gradual onset.In paper III, during the 52-week period, 292 athletes (91% of the study population) submitted weekly reports reporting a cumulative injury incidence of 3.57 injuries per 1000 hours of exposure to athletics. Most injuries (73%) were reported from training. There was a statistically significant difference with regard to gender and age in the proportion of athletes who avoided injury (P=0.043). Differences between event groups could not be statistically demonstrated (P=0.937). Ninety-six percent of the reported injuries were nontraumatic (associated with overuse). About every second injury (51%) was severe, causing a period of absence from normal training exceeding 3 weeks. Seventy-seven percent of the injuries occurred in lower extremities.In paper IV, 199 (68%) athletes reported an injury during the study year. The median time to first injury was 101 days (95% confidence interval (CI) 75–127). Univariate log-rank tests revealed risk differences with regard to athlete category (p = 0.046), serious injury (>3 weeks time loss) during the previous season (p = 0.039) and training load rank index (TLRI) (p = 0.019). Athletes in the third and fourth TLRI quartile had almost a twofold increased risk of injury compared to the first quartile. Youth male athletes with a previous serious injury had more than a fourfold increased risk of injury compared with youth females with no previous injury.

- Objectives To examine whether universal prevention via a digital health platform can reduce the injury incidence in athletics athletes aged 12-15 years and if club size had an influence on the effect of the intervention. Methods This was a cluster randomised trial where young athletics athletes were randomised through their club following stratification by club size into intervention (11 clubs; 56 athletes) and control (10 clubs; 79 athletes) groups. The primary endpoint was time from baseline to the first self-reported injury. Intervention group parents and coaches were given access to a website with health information adapted to adolescent athletes and were encouraged to log in and explore its content during 16 weeks. The control group continued training as normal. Training exposure and injury data were self-reported by youths/parents every second week, that is, eight times. The primary endpoint data were analysed using the log-rank test. Cox proportional hazards regression was used to analyse the second study aim with intervention status and club size included in the explanatory models. Results The proportion of completed training reports was 85% (n=382) in the intervention group and 86% (n=545) in the control group. The injury incidence was significantly lower (HR=0.62; chi(2)=3.865; p=0.049) in the intervention group. The median time to first injury was 16 weeks in the intervention group and 8 weeks in the control group. An interaction effect between the intervention and stratification factor was observed with a difference in injury risk between athletes in the large clubs in the intervention group versus their peers in the control group (HR 0.491 (95% CI 0.242 to 0.998); p=0.049). Conclusions A protective effect against injury through universal access to health information adapted for adolescent athletes was observed in youth athletics athletes. The efficacy of the intervention was stronger in large clubs.

- In this study, we examined knowledge and understanding of sport-related injuries among youth athletics (track and field) athletes and assessed their needs in managing any health problems. Qualitative data were collected via 12 focus groups with youth athletes (16-19 years) studying at Swedish sports high schools with an athletics specialism. All focus group discussions were audiorecorded and transcribed before being analysed using a thematic analysis approach. Four researchers independently reviewed the transcripts, generated codes and developed themes. Three overarching themes related to the athletes' knowledge and understanding of sport-related injury were developed: (1) awareness of injuries, (2) perception of injuries, and (3) factors contributing to injuries. The youth athletes were typically uncertain about how to acknowledge a sport-related injury. They expressed that knowledge about injuries was obtained in part by reflecting on the lived experiences of their peers. It was also demonstrated that there appears to be a 'culture of acceptance' regarding injury occurrence. In contrast, causes of injuries were viewed as dependent on multiple factors (eg, lack of context-specific knowledge about training practices). Regarding athletes' needs in managing injuries, an additional three themes were developed: (1) creating functioning elite sports environments, (2) application of knowledge and (3) fostering athletes. An apparent lack of structure and organisation related to the school environment was identified as an important issue to review to create opportunities for sustainable athletic development. The study identified areas that can be improved in Swedish sports high schools with an athletic specialism and could be applied in other youth sports contexts. The results of this study guide school stakeholders, alongside the sport governing bodies who have the mandate to influence activities in youth sports contexts, whereby special attention should be directed towards improving the social environment for youth athletes.
