Treatment of cardiovascular risk factors in type 2 diabetes : time trends and clinical practice
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objectives Patients with type 2 diabetes are at much greater risk of developing cardiovascular diseases (CVD), including coronary heart disease (CHD), compared to non-diabetics. The lowering of glucose, blood pressure, and plasma lipid levels has been shown to reduce CHD risk, and treatment goals for these risk factors are now part of clinical practice guidelines. However, the incidence and outcome of CHD in diabetic patients does not show the same favourable trend as in the general population. Thus, the overall aim of the thesis was to investigate how the treatment goals for CVD risk factors contained in the national guidelines for diabetes care were reflected in clinical practice, and to explore factors that might influence the remaining high incidence of CHD in the type 2 diabetes population. Research designs and results I. The effectiveness of the introduction of treatment goals for dyslipidaemia was evaluated in a retrospective observational population-based cross-sectional study of 971 diabetic patients participating in the Västerbotten Intervention Programme (VIP) 1995–2004. There was a stronger trend of decrease in cholesterol levels among patients with diabetes compared to the non-diabetic population in 2000–2004. Increased use of lipid-lowering agents influenced the trend in diabetic patients, even though only 25.3% received lipid-lowering treatment after the introduction of the new guidelines. II. The experiences of general practitioners relating to treatment practice for type 2 diabetes with specific focus on the prevention of cardiovascular disease were explored in a focus group study. The overall theme was ‘dilemmas’ in GPs’ treatment practice for patients with type 2 diabetes. Five main dilemma categories were identified. First, GPs were hesitant about labelling a person who feels healthy as ill. Second, as regards communicating a diabetes diagnosis and its consequences, GPs were unsure as to whether patients should be frightened or comforted. Third, GPs experienced uncertainty in their role: should they take responsibility for the care or not? Fourth, GPs expressed concern over a conflict between lifestyle changes and drug treatment. Fifth, the GPs described difficulties when attempting to translate science into reality. III. Screening for microvascular and coronary heart disease according to national guidelines was evaluated in a cross-sectional study of 201 screening-detected patients with type 2 diabetes 1.5±0.7 years after diagnosis. A larger proportion of diabetic patients was screened for nephropathy and retinopathy than for CHD. Twenty-three percent of the patients had minor or major ECG abnormalities, but ECG findings seemed to have little or no impact on CHD prevention using lipid-lowering medication and ASA. A clinical history of CHD correlated with a larger proportion of patients receiving secondary prevention. IV. Time trends relating to the achievement of treatment goals and 10-year CHD risk at three years of diabetes duration were studied in 19,382 patients with type 2 diabetes without CHD, who were reported by primary health care sources in the National Diabetes Register in 2003–2008. National treatment goals for glycaemia, blood pressure, total cholesterol, and LDL cholesterol were achieved in 78.4%, 65.5%, 55.6%, and 61.0%, respectively, of the diabetic patients in 2008 following a trend of improved results in 2003–2008. Absolute 10-year risk of CHD increased between year of diagnosis and follow up in a studied subgroup while modifiable risk decreased. Conclusions The introduction of treatment goals for dyslipidemia in Swedish national guidelines in 1999 were reflected in lowered cholesterol levels in people with type 2 diabetes. Since the introduction of the guidelines, an increasing number of diabetic patients are treated in accordance with guidelines. A remaining microvascular focus on the patients together with the revealed dilemmas within the GP’s consultation with diabetic patients might negatively influence the remaining high incidence of CHD in the type 2 diabetes population. Lipid levels, blood pressure and smoking are targets for further improvements.

Att leva i två världar : hälsoaspekter bland renskötande samer
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: There is a gap of knowledge of the health situation among the reindeer herding Sami in Sweden. The Swedish government has also got criticism for not taking responsibility for the Sami health. The aim of this thesis was to get more knowledge to understand the health situation of the reindeer herding Sami in Sweden. Furthermore, gender specific risk factors in the working environment among reindeer herders and their perception of healthcare and social services were investigated.Method: Cross–sectional questionnaires covering different aspects of health such as musculoskeletal disorders, trust for different healthcare providers and work related psychosocial factors was distributed to reindeer herding Sami and non-Sami populations. Interviews with nine reindeer herding Sami about trust in healthcare and social services were carried out and analyzed with thematic analysis. Sixteen discussion meetings with 80 reindeer herders focusing on psychosocial perspectives of working conditions in Sami communities were performed.Result: The prevalence of musculoskeletal symptoms from elbow, hand/wrist and lower back from male reindeer herders were higher compared to blue-collar worker. Psychosocial risk factors for health were identified such as high workload on a few herders, difficulties to get relief and support as well as to get appreciation in work and lack of participation in decisionmaking among women were common in the organization of reindeer husbandry. The trust in healthcare and social services was lower among reindeer herding Sami compared to non-Sami majority population. A hypothesis is that healthcare professionals do not know that the "Reindeer cloud" (metaphor to iCloud) affects all parts in the reindeer herders life. The distrust are influenced by historically traumas, reindeer herding Sami experiences from healthcare professionals and healthcare organization and culturally generated norms.Conclusio: The thesis hypothesized that health disorders, attitude towards healthcare and psychosocial environment are important aspects when trying to understand the health situation among the reindeer herding Sami. There is a need to introduce long-term public health work for all Sami people, to establish ethical guidelines for Sami health research and develop healthcare services that provides access to healthcare for the reindeer herding Sami, on equal terms.

Health-promoting health services : personal health documents and empowerment
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In 2003, the Swedish Parliament adopted a national public health policy that included the domain - “A more health-promoting health service”. Strategies and tools are needed in the work to reorient health services. Personal health documents are documents concerning a person’s health, and are owned by the individual. Several studies that have evaluated such documents indicate that they could be of interest in health-promotion work. However, there is insufficient knowledge concerning personal health documents that target adolescents, and little is known about the feasibility of such documents in a Swedish cultural context. The concept of empowerment is gaining increased interest for health services, but the associations between empowerment, self-rated health and health behaviour are sparsely studied. The overall aim of the thesis is to explore a strategy - empowerment - and a tool - personal health documents - that might facilitate the work of the public health goal of a health-promoting health service. Specific aims are to examine the feasibility of using personal health documents in health promotion; to examine professionals’ experiences of working with health promotion and personal health documents; to examine the association between personal health documents and self-reported health behaviour change; and to examine the perception of empowerment in relation to self-rated health and health behaviour among adolescents. Two personal health documents that targeted adults and adolescents were developed and evaluated. Distribution to adults in different settings was compared in a cross-sectional study (n = 1 306). Adolescents received the document in school, and surveys were performed at baseline and after one year (n = 339). Practical use and attitudes by document owners were studied by questionnaires. Teachers (n = 69) answered a questionnaire, and community health nurses were interviewed (n = 12). The interviews also explored nurses’ experiences of working with health promotion in general, and were analysed by qualitative methodology. Adolescents’ empowerment was examined by a questionnaire (n = 1 046). Most participants reported reading in the documents; writing in the documents varied between 16% (distribution in occupational health) and 87% (adolescents). The health document was perceived as useful by 35% of the adolescents. Factors significantly related to personal usefulness were being born outside Sweden, experiencing fair treatment by teachers, being a non-smoker and having a positive school experience. Community health nurses were striving for a balance of being a doer of practical, disease-oriented tasks and a health-promotion communicator. The structural organisation in health care centres was important for their work with health promotion and the health document. Teachers were generally in favour of continued work with the document. In different settings, between 10% and 26% of adults reported changes in their health situations as a result of reading the booklet. Self-reported changes in health situations were less likely using postal distribution, and there were no significant differences between the other types of distribution. Adolescents with low empowerment scores reported poorer self-rated health and more risk-taking behaviours such as smoking and binge drinking. To conclude, personal health documents are feasible to use in different settings. Health promotion in health services needs active support from leaders as well as adequate support systems. Findings suggest that personal health documents can be tools for promoting self-reported lifestyle changes among adults in different settings. There is a close relation among adolescents between low empowerment in the domain of health, low self-rated health and health behaviours such as binge drinking and smoking.

Identifying risk of type 2 diabetes : epidemiologic perspectives from biomarkers to lifestyle
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Type 2 diabetes is a significant health problem because of its high prevalence and strong association with cardiovascular morbidity and mortality. An increase of type 2 diabetes is predicted due to increasing obesity and sedentary lifestyle habits. The development from latent to diagnostic disease spans many years and during this time it is possible to prevent or postpone type 2 diabetes using lifestyle and pharmacological interventions. The objective of this thesis is to investigate and describe early patterns and risk indicators of type 2 diabetes. The focus is on type 2 diabetes as one component in metabolic syndrome, i.e. the clustering of several cardiovascular risk markers. Two studies based on the Västerbotten Intervention Programme (VIP) provided the data; one case-referent study nested within VIP which includes 237 diabetes cases that were clinically diagnosed 5.4 years after the health survey, each with two referents; and one panel study with 5 consecutive annual cohorts including subjects that participated in VIP between1990 and 1994 and returned to a follow-up after 10 years, a total of 16 492 individuals. Associations between risk markers and type 2 diabetes or metabolic syndrome are evaluated by several statistical techniques. A model of metabolic syndrome is hypothesized. A prediction model for developing type 2 diabetes among middle-aged individuals is proposed, where high risk is defined as having at least two out of three risk criteria (fasting plasma glucose ≥6.1 mmol/L, HbA1c ≥4.7% (Swedish Mono-S standard) and BMI ≥27 in men and BMI ≥30 in women). With positive predictive values of 32% in men and 46% in women, this model performs at least as well as other published prediction models. Information on family history of diabetes does not improve the result and the cumbersome oral glucose tolerance test is not needed. Therefore this model should be feasible for use in routine care. A model of metabolic syndrome with five composite factors, based on 14 variables including markers produced by adipose tissue and b-cells, suggest that obesity with insulin resistance and b-cell decompensation are the core perturbations in the early stages of type 2 diabetes, while inflammation and dyslipidemia could not be shown to be independent early risk indicators. The composite factors do not improve the prediction as compared to the single markers of fasting glucose, BMI and proinsulin and, possibly blood pressure values. Stress (measured as passive or tense working conditions) and weak social support (measured as emotional support), are suggested to be strong risk indicators along with high BMI for type 2 diabetes in women. In men BMI is predictive, but the stress variables are not shown to be associated with future type 2 diabetes. A social gap is indicated by double risk of metabolic syndrome among subjects with low (≤ 9 years at school) compared to high education (≥ 13 years). High consumption of Swedish smokeless tobacco, snuff (>4 cans/week), is independently associated with metabolic syndrome, obesity and hypertriglyceridemia, but not with dysregulation of glucose. To conclude, single markers, that are commonly used in daily practice, are useful and sufficient for identification of subjects that are in the early stages of type 2 diabetes. Obesity with insulin resistance and b-cell decompensation are the core perturbations in early development to T2DM. Lifestyle, socioeconomic and psychosocial markers, in addition to biomarkers, are important determinants of future type 2 diabetes and metabolic syndrome, albeit not similarly among men and women.

Abdominal obesity among older population in Indonesia : socioeconomic and gender inequality, pattern and impacts on disability and death
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Population ageing has contributed to the rise of chronic non-communicable diseases (NCDs). Concurrently, obesity prevalence is increasing in all age groups and has become a serious public health problem. Obesity is the main risk factors of the major chronic NCDs such as type 2 diabetes and has been linked to disability and mortality. Studies of socioeconomic inequalities in obesity among older people in Indonesia are scarce. Understanding socioeconomic inequalities are essential to develop appropriate health programme to improve the population health. This thesis describes the pattern of socioeconomic and gender inequality in abdominal obesity and analyses its impact on disability and all-cause mortality among older people in Indonesia.Methods: This thesis is based on four studies conducted in Purworejo Health and Demographic Surveillance System (HDSS) site in Purworejo district, Central Java, Indonesia. This thesis uses both quantitative and qualitative methods. The qualitative study (sub-study 1) was based on 12 Focus Group Discussions (FGDs) with 68 participants from different age groups, sex, and living area. Content analysis was used to describe the community perceptions on diabetes and its risk factors. The quantitative studies (sub-study 2 to 4) utilized longitudinal panel data from the 1st (n = 11,753 individuals) and 2nd wave (n = 14,235 individuals) of the WHO-INDEPTH Study on global AGEing and adult health (SAGE) conducted among all individuals aged 50 years and older in 2007 and 2010. Sub-study 2 used concentration index and decomposition analysis to analyse the pattern of socioeconomic and gender inequality in abdominal obesity. Sub-study 3 used linear regression to examine the association between abdominal obesity and disability. Sub-study 4 used Cox regression analysis with restricted cubic splines to examine the impact of abdominal obesity on all-cause mortality.Results: The FGDs reveals that the community holds unrealistic optimism in perceiving diabetes its risk factors. The community stated that chronic NCD such as diabetes is caused by modern lifestyles and mostly attacks those who are considered as the wealthy (sub-study 1). Socioeconomic inequality in abdominal obesity exists in Purworejo HDSS. Abdominal obesity was more prevalent among the affluent men and women, with a lesser inequality gaps between rich and poor among women. The main contributing factors to inequalities in abdominal obesity were occupation, wealth index, and education (sub-study 2). In three-year period, the mean waist circumference decreased significantly among the poor. An increase in waist circumference was significantly associated with disability, and the poor people were more disabled compared to the rich (sub-study 3). A U-shaped association was observed between waist circumference and all-cause mortality, particularly among women. This indicated an increased risk of mortality in the lower and upper end of the waist circumference distribution. The poor with low waist circumference had a higher risk of mortality than the rich (sub-study 4).Conclusion: Abdominal obesity was disproportionately more prevalent among older Indonesian women. Though the wealthy people have higher burden of abdominal obesity, the poor people experiences more disability and higher risk of death. Misperception on chronic NCDs and its risk factors exist among the Indonesian population. Abdominal obesity prevention strategies are needed to prevent chronic NCDs, disabilities, and mortality among Indonesian older population. The prevention strategies should be culturally sensitive and address all socioeconomic levels. Special attention should be given to disadvantaged women as the most vulnerable group.

Alcohol consumption during pregnancy : Prevalence, predictors and prevention
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is well established that fetal alcohol exposure can disturb the development of the fetus and cause a range of effects for the affected child. However, research on the effects of exposure to lower levels is inconclusive and the subject is debated. Based on the precautionary principle women in many countries, Sweden included, are advised to maintain total abstinence throughout pregnancy. Regardless, studies have shown that a significant proportion of women consume alcohol around conception and throughout pregnancy. The overall aim of this thesis was to generate knowledge about the prevalence, predictors and prevention of alcohol consumption among women before and during pregnancy.The aim was addressed in five studies using several datasets and methods. A systematic review of the international literature was undertaken to identify predictors of alcohol consumption during pregnancy (Study I). Questionnaires to midwives were used to investigate the alcohol-preventive work in antenatal care in Sweden (Study II). Questionnaires were also used to gather data on alcohol consumption before and during pregnancy from pregnant women across Sweden and from women who had given birth to a child in one area of Sweden (Study III and IV). Focus group interviews were used to assess non-pregnant women’s voices on alcohol consumption and pregnancy in Sweden (Study V).The results from the studies showed that alcohol consumption was common among women of childbearing age in Sweden (Study III-V) and that there were social expectations for women to drink (Study V). During pregnancy, the expectation was the opposite, as pregnant women were expected to abstain from all alcohol consumption (Study V), which is in line with the total abstinence recommendation from antenatal care. The national “Risk Drinking” project led to revised alcohol-preventive routines in Swedish antenatal care, including screening of all pregnant women for hazardous alcohol use in the year preceding pregnancy, an important predictor of drinking during pregnancy (Study II). A great majority of pregnant women and new mothers reported abstinence from alcohol after pregnancy recognition (Study III and IV), yet the level of reported alcohol consumption during pregnancy appeared to be affected by formulation of the question (Study IV). Factors associated with more drinking during pregnancy in Sweden were: living in a major city, older maternal age, tobacco use, low social support, stronger pre-pregnancy drinking habits and stronger social drinking motives (Study III). In the international research, pre-pregnancy drinking habits, exposure to abuse or violence, high income or social class and positive screen for dependence were the factors most consistently reported to be associated with more drinking during pregnancy (Study I). Women of childbearing age were uncertain about the potential effects of drinking in the period around conception and the social expectations to abstain did not seem to be as strong in this period as after pregnancy recognition (Study V). A majority of women reported having reduced their alcohol consumption only after they became aware that they are pregnant, meaning that they could have been dinking for several weeks in early pregnancy (Study III).

Physical activity on prescription with access to counsellor support implemented in routine care : Healthcare and patient perspectives
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The Swedish PAP (physical activity on prescription) programme FaR®, introduced in 2001, has been adopted by all Swedish regions, which are responsible for provision of healthcare in Sweden. Several studies have shown positive outcomes of the Swedish PAP on patients’ physical activity and other health-related outcomes. There are no guidelines for best practises of the Swedish PAP, which has led to the development of different organizational structures for its delivery. This thesis project was developed with the ambition of providing knowledge for further development of PAP in clinical practise.Aim: The overall aim was to investigate and generate improved understanding of a structure for physical activity on prescription with access to physical activity counsellors, implemented in routine healthcare.Methods: To address the overall aim, four real-world studies with different design and analysis methods were carried out. The study population consisted of patients 18 years or older prescribed PAP in primary and secondary care in Region Kronoberg’s healthcare organization. Study I investigated characteristics of healthcare delivery of PAP over a four-year period, including all patients prescribed PAP in these years. Study II explored factors that influenced patient’s long-term engagement in physical activity after prescription. Study III investigated differences in physical activity and health-related quality of life (HRQoL) at one-year follow-up between patients who used versus patients who did not use counsellor support after prescription. Study IV investigated factors associated with patients increase in physical activity at one-year follow-up. Data sources for the studies were electronic medical records (Studies I, II, III and IV), individual interviews (Study II) and a baseline and a follow-up questionnaire (Studies III and IV). Different statistical analyses were performed in Studies I, III and IV. Study II used qualitative content analysis based on an approach including both inductive and deductive analysis. The final study samples of PAP recipients were N = 4,879 (Study I), n = 13 (Study II), n = 400 (Study = III) and n = 355 (Study IV).Results: Study I: 4,879 PAP recipients were identified, one-third had used the offer of counsellor support. PAP recipients had a high frequency of diagnosis and healthcare consumption prior to PAP. Counsellor users had higher frequency of multiple diagnoses and healthcare visits than non-counsellor users. The main prescriber of PAP was physicians and the main prescribing setting was primary care. Study II: PAP recipients’ long-term engagement with physical activity was influenced by the determinants of capability, opportunity, and motivation. Receiving a prescription of physical activity, and professional counselling and follow up from a physical activity counsellor, and adaption of PAP to the individual’s capacity were important for patients change of physical activity. Study III: Counsellor users had better outcomes in both physical activity and HRQoL than non-users of this support. Study IV: Nearly half of the PAP recipients had increased physical activity one year after prescription. Increased physical activity was positively associated with lower baseline activity, counsellor use, and positive perception of given support after PAP.Conclusions: Patients who were prescribed PAP had a high frequency of diagnoses and high healthcare consumption in the year prior to the prescription. Due to the positive findings regarding patient outcomes on physical activity, and patient experiences of counsellor support, it could be suggested that individualized counselling and follow up by a physical activity counsellor is of importance for patients’ engagement in physical activity, especially for patients with lower baseline activity. Since increased activity was also seen among nonusers of counsellor support, a general recommendation for physical activity counsellor support for all PAP recipients could not be suggested.

Insights on weight maintenance and impacts of obesity for two rural populations in the United States and Sweden
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Obesity is a serious public health concern worldwide, and nearly 40% of all adults in the United States and 21% in Sweden are now living with obesity. Efforts focusing mainly on weight loss have fallen short in reducing obesity prevalence. There is a great need for improved insight into what factors may promote a healthy weight, thereby avoiding the adverse health outcomes linked to obesity. Primary weight maintenance is a prevention strategy that emphasizes keeping a long-term stable weight in the non-obese range.Aim: The overall aims of this thesis were to improve understanding of the patterns of obesity and obesity-related mortality among rural adults in Central New York State (U.S.) and Västerbotten County (Sweden), and to explore factors that are related to primary weight maintenance.Material and methods: Data from U.S. health surveys and health examinations in Sweden were used to compare twenty-year (1989-2009) trends in body mass index (BMI) and obesity using multi-factor analysis of variance. The association between obesity and risk of 1) premature all-cause death, and 2) premature circulatory death, was compared between the U.S. and Sweden using proportional hazards regression. In 2009, a longitudinal questionnaire of attitudes, behaviors and perceptions regarding weight maintenance was administered to U.S. subjects. Associations between ten-year weight change and survey variables were tested using multiple linear regression, separately for sex and age strata. To gain a deeper understanding of influences, facilitators and barriers to healthy eating and physical activity, a qualitative interview study was conducted with U.S. women aged 26-35, with data analyzed by qualitative content analysis.Results: Over twenty years, BMI increased for both men and women in all age strata in both countries, and those with no university education consistently had higher BMI than their university-educated counterparts. BMI increased more for younger groups (ages 36-45) compared to those aged 46-55 and 56-62. U.S. females aged 36-45 showed the greatest increases in average BMI, particularly when comparing 1999 to 2009. Increases in the prevalence of obesity (BMI≥30) in Sweden were more modest than in the U.S. Severe obesity (BMI≥35) was associated with significantly increased risk of premature death from all causes and from circulatory causes for all subjects. Severe obesity was less common in Sweden (2% of men, 3% of women) than in the U.S. (8% of men, 9% of women). Nonetheless, severely obese Swedish men had 2.9 times the risk of premature death from all causes compared to those of normal weight, and 4.9 times the risk for circulatory causes. The gradient of risk among U.S. men was significantly lower than in Sweden; those with severe obesity had a 1.6 times increased risk for all-cause premature death and 3.2 times increased risk for premature circulatory death. The pattern of risk among women did not differ between countries. Longitudinal analysis of U.S. health survey participants showed that women aged 26-35 gained the most weight of any group (mean=10.3kg gained over ten years). The variables found to be associated with ten-year weight change were different across sex and age groups. Among women, all variables associated with weight change were exercise-related. Among men, three of the four predictors were focused on eating habits. Interviews with women aged 26-35 revealed the challenges of healthy eating and engaging in physical activity. Women often identified as caregivers for others, and those with more social support, who were financially stable and showed self-efficacy around healthy choices were able to more consistently engage in healthy habits.Conclusions: Obesity is an increasing problem for the rural adult population in both the U.S. and Sweden. When primary weight maintenance strategies are designed to support individuals towards healthy eating and increased physical activity, the complexity of the living environment must be considered. Individual conditions and personal relationships as well as the physical environment, home environment and work environment must be included in the assessment. Development of targeted programs for primary weight maintenance should be a focus of public health work for adults in rural areas in both Sweden and the U.S.

"Det är inte mig det är fel på, det är huset" : en studie av prognosfaktorer och bemötande med fokus på sjuka hus-syndromet
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Bakgrund: Sick Building Syndrome, SBS, är fortfarande 2015 ett tillstånd som vållar mycket diskussion. Symtomen kan grupperas i slemhinnesymtom, hudsymtom och allmänna symtom. I definitionen ingår att personen/ personerna som fått symtom har exponerats för dålig inomhusluft i en speciell byggnad. När personen inte är i byggnaden så förbättras eller försvinner symtomen. Många olika faktorer kan orsaka eller medverka till uppkomst eller försämringar av SBS-symtom, som t.ex. luftens innehåll av olika ämnen, luftflöden, temperatur, buller, fukt och mögel. Utbredd enighet finns om att fukt och mögel i byggnaderna påverkar eller ger upphov till symtom hos vissa personer som exponeras där. Psykosociala faktorer som arbetets organisation och krav och individuella faktorer som kön och personlighet påverkar också.Syfte: Hypotesen är att faktorer som tidigare hälsa, åtgärder på arbetet, tid, behandling, personlighet och copingresurser alla kan påverka prognosen för SBS-patienterna. Syftet med avhandlingen är att undersöka hur symtomen påverkar arbetsförmågan och om patienterna återhämtar sig från SBS-symtomen. Ett annat syfte är att undersöka bemötande och de erfarenheter som SBS-symtomen gett en grupp av informanter med SBS. För att förstå om personlighet mätt med självbild och coping hade någon betydelse för progressionen av SBS-symtom och arbetsförmåga gjordes jämförelser av personlighet mellan en patientgrupp med SBS, en patientgrupp med handeksem, en patientgrupp med elkänslighet och en normalpopulation.Metod: En uppföljningsenkät skickades till 239 patienter med SBS-symtom som under åren 1986–1998 blivit undersökta och bedömda på Universitets-sjukhuset i Umeå, Sverige. Frågorna innehöll social och medicinsk status, nuvarande symtom, behandlingar, åtgärder på arbetsplatsen, coping och självbild och svarsfrekvensen var 79,1%. Prognos och riskfaktorer för prognos beräknades för SBS-patienterna. Mätningar av personlighetsfaktorer gjordes med instrumentet Structural analysis of Social Behaviour, SASB, och coping mättes med Coping Resources Inventory, CRI. Likadana uppföljningsenkäter skickades till en grupp patienter med handeksem och patienter med upplevd elkänslighet. Svarsfrekvensen var 68% respektive 73% och enkätsvaren har sedan analyserats och jämförts genom beräknngar av prognos med fokus på självbild och coping för SBS-patienterna och handeksempatienterna. Jämförelser gjordes också mellan de tre olika grupperna och en kontrollgrupp vad gäller självbild och coping. För att undersöka erfarenheterna av SBS-symtomen och bemötandet genomfördes kvalitativa intervjuer med 10 informanter som hade eller hade haft SBS-symtom. Fem av dem hade diagnostiserats en längre tid tillbaka medan de andra fem hade haft SBS-symtomen en kortare period. Semi-strukturerade intervjuformulär användes vid intervjuerna och anlyserades med kvalitativ innehållsanalys.Resultat: Graden och svårigheten av SBS-symtomen minskade över tid trots att nästan hälften av SBS-patienterna beskrev att symtomen var mer eller mindre oförändrade efter 7 år eller mer. Risken att ha symtom vid uppföljningen var större för de patienter som remitterats sent efter symtomdebut men även för de som hade kort uppföljningstid. Risken att inte ha någon arbetsförmåga vid uppföljningen var signifikant ökad om det var mer än ett års skillnad mellan symtomdebut och första läkarbesöket p.g.a. SBS-symtomen eller om patienten vid första undersökningen hade fler än 5 SBS-symtom. Dagliga aktiviteter som t.ex. bussåkning förvärrade också symtomen för patienterna. Informanternas upplevelser av SBS-symtomen från början visar en influensaliknande bild med rinnande näsa och ögon, heshet, hosta och huvudvärk. Informanterna agerar för att klara av situationen när symtomen förvärras. Genom hela processen upplever de en brist på bekräftelse och stöd från arbetsgivare, primärvård, företagshälsovård och fastighetsförvaltare.Alla tre patientgrupperna hade högre värden i spontan och positiv självbild i jämförelse med en kontrollgrupp. De hade också alla lägre värden i kontroll medan patienterna med handeksem och de med elkänslighet hade högre värden i sin negativa självbild. När det gäller coping skilde sig inte patientgrupperna från kontrollgruppen utom i CRI kognitiv där SBS-patienterna hade hög poäng i motsats till handeksempatienterna som hade låg poäng i samma domän. De elkänsliga patienterna hade i stället höga poäng i domänen andlig/filosofisk. Självbild eller copingförmåga var inte associerade med SBS-symtom eller symtom av handeksem vid uppföljningen och deras personlighet påverkade inte arbetsförmågan. Tidigare atopisk dermatit var en signifikant risk för kvarvarande symtom men inte för arbetsförmågan hos handeksempatienterna.Slutsats: En grupp av patienter som tidigare diagnostiserats för symtom från inomhusmiljön har kroniska symtom och påverkan på sitt sociala liv. Över tid minskar symtomen. Resultaten pekar på att ett tidigt omhändertagande är av vikt. SBS-symtomen är från början svåra att upptäcka för alla inblandade och kunskap om hur symtomen kan uppstå i dagligt liv kan bidra till bredare förståelse. Erfarenheterna från personer med SBS visar på avsaknad av bekräftelse och stöd från vården, företagshälsan, arbetsgivare och fastighetsförvaltare. Sambandet mellan symtom och inomhusmiljö får inte glömmas bort. Stöd och bekräftelse innebär också kunskap om skyldigheter för arbetsgivare och fastighetsförvaltare.Skillnad i självbild i jämförelse med en kontrollgrupp ses hos patientgrupperna med symtom som är delvis oförklarade men också hos handeksempatienter med ett väletablerat tillstånd. Det kan innebära att patienter med kroniska tillstånd överlag kan avvika från den allmänna populationen. Patienterna visar som grupp en hög positiv och hög spontan självbild som kan leda till svårigheter att sätta gränser. Detta kan leda till en mental stress och i förlängningen också ge en ökad känslighet/sårbarhet för miljöfaktorer.

- BackgroundIndigenous peoples with traditional lifestyles worldwide are considered particularly vulnerable to climate change effects. Large climate change impacts on the spread of infectious vector-borne diseases are expected as a health outcome. The most rapid climate changes are occurring in the Arctic regions, and as a part of this region northernmost Sweden might experience early effects. In this thesis, climate change effects on the lives of Sami reindeer herders are described and 30 years of weather changes are quantified. Epidemiology of the climate sensitive human infection tularemia is assessed, baseline serologic prevalence of tularemia is investigated and the disease burden is quantified across inhabitants in the region.MethodsPerceptions and experiences of climate change effects among the indigenous Sami reindeer herders of northern Sweden were investigated through qualitative analyses of fourteen interviews. The results were then combined with instrumental weather data from ten meteorological stations in a mixed-methods design to further illustrate climate change effects in this region. In two following studies, tularemia ecology and epidemiology were investigated. A total of 4,792 reported cases of tularemia between 1984 and 2012 were analysed and correlated to ecological regions and presence of inland water using geographical mapping. The status of tularemia in the Swedish Arctic region was further investigated through risk factor analyses of a 2012 regional outbreak and a cross-sectional serological survey to estimate the burden of disease including unreported cases.ResultsThe reindeer herders described how the winters of northern Sweden have changed since the 1970s – warmer winters with shorter snow season and cold periods, and earlier spring. The adverse effects on the reindeer herders through the obstruction of their work, the stress induced and the threat to their lifestyle was demonstrated, forcing the reindeer herders towards the limit of resilience. Weather data supported the observations of winter changes; some stations displayed a more than two full months shorter snow cover season and winter temperatures increased significantly, most pronounced in the lowest temperatures. During the same time period a near tenfold increase in national incidence of tularemia was observed in Sweden (from 0.26 to 2.47/100,000 p<0.001) with a clear overrepresentation of cases in the north versus the south (4.52 vs. 0.56/100,000 p<0.001). The incidence was positively correlated with the presence of inland water (p<0.001) and higher than expected in the alpine and boreal ecologic regions (p<0.001). In the outbreak investigation a dose-response relationship to water was identified; distance from residence to water – less than 100 m, mOR 2.86 (95% CI 1.79–4.57) and 100 to 500 m, mOR 1.63 (95% CI 1.08–2.46). The prevalence of tularemia antibodies in the two northernmost counties was 2.9% corresponding to a 16 times higher number of cases than reported indicating that the reported numbers represent only a minute fraction of the true tularemia.ConclusionsThe extensive winter changes pose a threat to reindeer herding in this region. Tularemia is increasing in Sweden, it has a strong correlation to water and northern ecoregions, and unreported tularemia cases are quite common.
