Tidskriftsartikel (refereegranskat)abstract
- Regular physical activity (PA) and limited sedentary time (SED) are highly recommended in international guidelines for patients after a myocardial infarction (MI). Data on PA and SED are often self-reported in clinical practice and, hence, reliable and valid questionnaires are crucial. This study aimed to assess the test–retest reliability, criterion validity and agreement of two PA and one SED questionnaire commonly used in clinical practice, developed by the Swedish National Board of Health and Welfare (BHW) and the Swedish national quality register SWEDEHEART. Data from 57 patients (mean age 66 ± 9.2 years, 42 males) was included in this multi-centre study. The patients answered three questionnaires on PA and SED at seven-day intervals and wore an accelerometer for seven days. Test–retest reliability, criterion validity and agreement were assessed using Spearman’s rho and linearly weighted kappa. Test–retest reliability was moderate for three of the six-sub questions (k = 0.43–0.54) within the PA questionnaires. For criterion validity, the correlation was fair within three of the six sub-questions (r = 0.41–0.50) within the PA questionnaires. The SED questionnaire had low agreement (k = 0.12) and criterion validity (r = 0.30). The studied questionnaires for PA could be used in clinical practice as a screening tool and/or to evaluate the level of PA in patients with an MI. Future research is recommended to develop and/or evaluate SED questionnaires in patients with an MI.

Tidskriftsartikel (refereegranskat)abstract
- Background: Concerns about falling, a construct related to fear of falling, is increased in people with Parkinson's disease (PD) and is recognized as a barrier for exercise, negatively affecting health-related quality of life and participation. Aim: To investigate modifiable factors associated with concerns about falling in elderly with mild-to-moderate PD. Methods: Eighty-nine elderly (39 females, mean age 73 years) with mild-to-moderate PD were recruited. Concerns about falling were assessed with the Falls Efficacy Scale-international, that is, the dependent variable in multiple linear regression analysis. Independent variables included both motor (e.g., objective measures of physical activity and gait) and nonmotor aspects such as depressive symptoms. Results: A model with three significant independent variables explained 33% of the variance in concerns about falling. According to the standardized regression coefficients (β), the strongest contributing factor was depressive symptoms (0.40), followed by balance performance (−0.25), and use of mobility devices (0.24). Conclusions: The findings imply that factors associated with concerns about falling are a multifactorial phenomenon. For its management in elderly with mild-to-moderate PD, one should consider depressive symptoms, balance deficits, and mobility devices.

Correlations between insulin-degrading enzyme and metabolic markers in patients diagnosed with type 2 diabetes, Alzheimer's disease, and healthy controls : A comparative study
- 2024
-

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: This study aimed to explore correlations between insulin-degrading enzyme (IDE) and markers of metabolic function in a group of patients diagnosed with type 2 diabetes mellitus (T2DM) or Alzheimer's disease (AD) and metabolically healthy volunteers.METHOD: We included 120 individuals (47 with T2DM, 9 with AD, and 64 healthy controls). Serum levels of IDE were measured with commercial kits for ELISA. Differences in IDE levels between groups were analyzed with non-parametric ANCOVA, and correlations were analyzed with Spearman's rank correlations. We also investigated the influence of age, sex, and the use of insulin on the correlation using a non-parametric version of partial correlation.RESULTS: Patients diagnosed with T2DM had higher IDE levels than patients diagnosed with AD and healthy controls after adjustment for age and sex. IDE was increasingly associated with body mass index (BMI), fasting blood glucose, C-peptide, hemoglobin A1c (HbA1c), insulin resistance, and triglycerides. In stratified analyses, we found a decreasing partial correlation between IDE and HbA1c in patients diagnosed with AD and a decreasing partial correlation between IDE and C-peptide in healthy controls. In patients diagnosed with T2DM, we found no partial correlations.CONCLUSION: These results indicate that IDE is essential in metabolic function and might reflect metabolic status, although it is not yet a biomarker that can be utilized in clinical practice. Further research on IDE in human blood may provide crucial insights into the full function of the enzyme.

- PURPOSE: Decreasing levels of serum insulin-degrading enzyme (IDE) have been associated with an increased risk for Alzheimer´s disease (AD) in patients with type 2 diabetes mellitus (T2DM). Research on serum IDE levels in patients with T2DM is sparse and the aim of this study was to explore serum levels of IDE in patients with T2DM.METHOD: Blood serum samples were obtained from a biobank. Samples from subjects with T2DM and without metabolic disease were divided into subgroups; lifestyle treatment (n = 10), oral antidiabetic treatment (n = 17), insulin treatment (n = 20) and metabolically healthy controls (n = 18). Serum levels of IDE were analysed using specific ELISA assays.RESULTS: Serum levels of IDE were elevated in subjects with T2DM compared to metabolically healthy individuals (p = 0.033). No significant differences were detected between treatment subgroups.CONCLUSION: The present study indicates that patients with T2DM have increased serum IDE levels, compared to metabolically healthy individuals. However, for IDE to be clinically useful as a biomarker, its full function and possible use needs to be further elucidated in larger studies showing reproducible outcomes.

Improving movement behavior in office workers : effects of two multi-level cluster-RCT interventions on mental health
- 2024
-
Ingår i: BMC Public Health. - : Springer. - 1471-2458. ; 24:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: We have previously reported on the design and efficacy of two cluster-randomized multi-level workplace interventions, attempting to decrease sedentary behavior (SED) or increase moderate to vigorous physical activity (MVPA) among office workers to improve mental health outcomes. The aim of this study was to investigate intervention effects on mental health outcomes, i.e., mental wellbeing, depression or anxiety symptoms, and stress immediately after the 6-month intervention period.Methods: Teams of 263 office workers were cluster-randomized to one of two interventions or a waitlist control group. The PA intervention (iPA) focused on increasing MVPA and the SED intervention (iSED) on reducing SED. Both multi-level interventions targeted individual office workers and their social, physical, and organizational work environment, incorporating counseling based on cognitive behavioral therapy and motivational interviewing. Mental health outcomes were assessed using validated questionnaires before and immediately after the intervention. Intervention effects were analyzed using linear mixed effects models.Results: Participants were mostly female and highly educated, with a mean age of 42 years and had favorable levels of mental health at baseline. Mental wellbeing improved for the iSED group (β = 8, 95% CI 1 to 15, p = 0.030) but not for the iPA group (β = 6, 95% CI -1 to 12, p = 0.072) compared to the control group. No effects were found for depression or anxiety symptoms or stress.Conclusions: The multi-level interventions improved mental wellbeing among this population of office workers, reaching statistical significance in the iSED group. The size of the effect can be regarded meaningful, considering favorable mental health and high PA level at baseline. Thus, workplace interventions that provide support on multiple levels appear to have potential for improving mental wellbeing, but not reducing ill-health variables, among healthy office workers. More research is needed to understand the mechanisms through which such improvements can be achieved and to identify the most effective intervention components.

Tidskriftsartikel (refereegranskat)abstract
- The impact of exercise interventions on physical activity (PA) remains undetermined in intermittent claudication, which is why it is important to include objectively measured PA as an additional endpoint. The aim of this prespecified secondary analysis of a randomized clinical trial was to investigate the impact of unsupervised Nordic pole walk advice (WA) alone or in combination with hospital-based supervised exercise (SEP) or home-based structured exercise (HSEP) on PA in patients with intermittent claudication.In total, 166 patients with intermittent claudication (mean age=72 [SD=7.4] y; 41% women) were randomized to 3 intermittent claudication-treatment strategies: WA, WA+SEP, or WA+HSEP. All patients received Nordic poles and standardized WA (≥30min, 3 times weekly). Patients randomized to HSEP and SEP accepted participation in an additional 6-months exercise program. PA was measured with an accelerometer-based activPAL3 monitor for 7days at baseline and at 3, 6, and 12months. PA outcomes were steps per day, time spent within a stepping cadence ≥100 steps per minute, time spent upright, number of body transitions from sitting to standing, and number of sitting bouts of >30minutes and>60minutes.At 1year, no intergroup differences were observed in any of the PA variables, whereas significant intergroup differences were observed at 3months regarding time spent within a stepping time cadence ≥100 steps per minute. The mean change for HSEP (2.47 [SD=10.85] min) was significantly different from the mean change for WA (-3.20 [SD=6.24] min). At 6months, the number of sitting bouts (>60min) for SEP was significantly different from WA (mean change=0.24 [SD=0.69] vs -0.23 [SD=0.81]).This study indicates that the addition of 6months of HSEP or SEP does not improve PA at 1year, as compared to unsupervised WA alone. Factors of importance for increasing PA in patients with intermittent claudication require further investigation.At the 1-year follow-up, the addition of intermittent claudication-tailored additional exercise strategies did not improve daily PA in patients with intermittent claudication compared with unsupervised Nordic pole WA alone. Future studies may explore the role of behavior change techniques to increase PA in this patient group.

An interactive health technology solution for encouraging physical activity : a first model based on a user perspective
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Globally, the level of physical inactivity is increasing. The overall aim of this thesis was to develop and test a first model of an interactive health technology solution (called App&Move) that should encourage physically inactive adults to be more physically active. App&Move was iteratively developed based on the user perspective, a so-called user-centered design. First, available technology was assessed; the validity and reliability of one smartphone pedometer application and one commonly used traditional pedometer were investigated. It was found that none of the investigated pedometers could measure correctly in all investigated situations. However, measurements by a smartphone appli-cation was identified to have high potential when aimed at monitoring physical activity in everyday situations. As the next step, a questionnaire was developed and distributed in central Sweden. The 107 respondents who answered the questionnaire were divided and analyzed in groups of users and non-users of physical activity self-monitoring technology. The results showed that users and non-users of such technology mainly had similar opinions about desirable functions of the technology. To gain further knowledge concerning how to design App&Move, the target group physically inactive non-users participated in focus group interviews. Important results were that the technology should focus on encouragement rather than measurements and that it preferably should be integrated into already existing technology, if possible already owned and worn by the person. A brainstorming workshop confirmed that the smartphone was a suitable platform, and a decision to develop a smartphone application was taken. A first draft of App&Move was developed, focusing on encouragement and measuring everyday activity and exercise in minutes per day. App&Move was based on available physical activity recommendations and strategies for successful behavior change. App&Move was positively received in a user workshop and thereafter iteratively refined and developed based on further user input. App&Move was usability tested in 23 physically inactive adults who used App&Move for four weeks and answered two questionnaires. Three usability aspects, effectiveness, efficiency and satisfaction, were assessed as follows: acceptable, high and medium, and slight increases in activity minutes were observed during the test period. To conclude, this thesis has investigated the user perspective of physical activity self-monitoring technology with a target group of physically inactive adults. Based on these findings, a behavior change application for smartphone, App&Move, was presented. The usability test indicated promising results with respect to usability and indicated an ability to encourage the users to physical activity to some extent.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To evaluate the validity of the Previous Day Physical Activity Recall (PDPAR) as a physical activity diary in adolescents using two accelerometer intensity classifications.METHODS: One hundred eighth graders (47 boys, 53 girls) used the PDPAR as a daily diary and wore MTI accelerometers for four consecutive days. Measured time spent in moderate (> or = 3 METs) and vigorous (> or = 6 METs) activity was based on two published MTI cut-point limits (that of Freedson et al./Trost et al. and that of Puyau et al.). Spearman rank order correlations and Bland-Altman plots were used to examine agreement between MTI and PDPAR diary estimates of activity.RESULTS: MTI estimates of mean minutes per day of total moderate to vigorous physical activity (MVPA) were 65.2 (+/-43.2) using the Freedson et al./Trost et al. cutoffs and 17.5 (+/-18.5) using those of Puyau et al., while students self-reported 105.1 (+/-80.1) min.d(-1). Significant relationships were observed between the diary and MTI for total MVPA using either the Freedson et al./Trost et al. (r = 0.42) or Puyau et al. (r = 0.41) cutoff as well as raw counts (r = 0.44). Plots showed reasonable agreement between the diary and Freedson et al./Trost et al. MTI estimates of MVPA for daily totals of < or = 60 min, but the Puyau et al. estimates were consistently lower. Diaries overestimated activity as time increased when compared to either MTI cut point, especially on vigorous activity.CONCLUSIONS: Time estimates of MVPA differed by assessment tool, but diary estimates showed adequate association with the MTI. Diaries reflected intensity-specific activity, corresponding most closely with the Freedson et al./Trost et al. classification of moderate, but substantially overestimated vigorous activity regardless of cut-point method. This is likely due to the measurement characteristics of the PDPAR, which classifies activities in 30-min blocks, as well as the nature of common activities in which high levels of intensity are not sustained.

- Accelerometrar används i stor utsträckning inom forskning och i viss grad i klinisk verksamhet för att fastställa fysisk aktivitet, men de ställer krav på användarna. God kännedom krävs om utformning av mätprotokoll och bearbetning av rådata till användbara mått, som kan användas i lämpliga statistiska analyser för att undvika mätfel.Mätfel medför felskattning av den fysiska aktiviteten, uteblivna gruppskillnader, försvagade samband med hälsa och felaktiga slutsatser om interventionseffekter.Mätning av fysisk aktivitet i klinisk verksamhet främjas genom samarbete mellan kliniskt verksamma, kliniska forskare och forskare med metodologisk kompetens inom fysisk aktivitetsmätning.

- The development of accelerometers has revolutionized measurement of physical activity, and they are used to a large extent in research and have started to be implemented into clinical settings. However, achievement of reliable outcomes requires good methodological knowledge and skills by the user. Otherwise, significant measurement errors may occur, interfering with assessment of the physical activity level in the population, group differences, associations with health parameters or effect of treatments. This paper by the Swedish Network for Objective Measurement of Movement (NORM) provides an overview of physical activity measurement including sections of data collection, processing of raw data into useful metrics and statistical analysis. It targets users of accelerometer in research, health care and national surveys.

Physical activity, visceral adipose tissue, and cardiovascular disease in older adults : associations and effects
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BACKGROUND: Cardiovascular disease (CVD) poses a substantial public health burden and is the leading cause of mortality in older adults. With the population aging rapidly, interventions aimed at improving modifiable risk factors for CVD, such as physical inactivity and visceral obesity, could play an important role in reducing its burden, provided they are proven effective.PURPOSE AND AIMS: The overall purpose of this thesis was to create a deeper understanding of the links between physical activity, visceral adipose tissue (VAT), and CVD in older adults, by studying it from both an observational and an interventional perspective. The specific aims were to investigate the associations of objectively measured physical activity and VAT with the risk of CVD and all-cause mortality, to investigate the effect of structured physical activity (exercise) on VAT, and to review the effects of exercise on CVD and all-cause mortality based on evidence from randomized controlled trials (RCTs).METHODS: This thesis comprised two prospective cohort studies, one RCT, and one narrative review of evidence from RCTs. The cohort studies included about 3,300 men and women aged 70 years with baseline data on physical activity and VAT mass, as obtained using accelerometry and dual-energy X-ray absorptiometry, respectively. Cases of stroke, myocardial infarction, and all-cause mortality during follow-up were collected from Swedish nationwide registers. The RCT included 77 men and women aged 70 years with visceral obesity who were randomly allocated to either 10 weeks of supervised vigorous-intensity exercise or to no exercise, with VAT mass measured before and after the intervention. In the review, evidence from published RCTs and meta-analyses of RCTs reporting on the effects of exercise on CVD (N=19,162) and all-cause mortality (N=37,443) in general older adults and in individuals with chronic conditions (such as obesity, type 2 diabetes, and preexisting CVD) were reviewed.MAIN FINDINGS: In the cohort studies, greater amounts of physical activity of any intensity, but especially that of moderate to vigorous intensity, were associated with lower risk of stroke, myocardial infarction, and all-cause mortality. Conversely, greater VAT mass was associated with higher risk of stroke or myocardial infarction. In the RCT, short-term vigorous-intensity exercise seemed to decrease VAT mass slightly, but the effect was not statistically significant. Finally, the review showed that there is currently no convincing evidence from RCTs that exercise effectively reduces the risk of CVD or all-cause mortality, which stands in sharp contrast to the strong associations typically reported in observational studies. The reasons for the conflicting findings are likely complex and multifactorial. In the RCTs, a lack of statistical power could partly explain why no effects have been detected in the general population of older adults, but it is unlikely to explain the null findings in clinical populations, as some of these trials, including meta-analyses of such trials, have been large. Other potential explanations could be a ceiling effect due to the inclusion of participants who were healthier and more physically active than the general population, or that an effect of exercise was masked by the use of effective medications such as antihypertensives and lipid-lowering agents. On the other hand, observational studies have likely overestimated the benefits of physical activity, because these studies are vulnerable to selection bias, reverse causation, and unmeasured confounding, such as from heritable influences.CONCLUSIONS AND IMPLICATIONS: Despite strong associations, the protective effect of physical activity as a single intervention against CVD and all-cause mortality in older adults is probably not as substantial as is commonly presumed. To uncover the true role of physical activity in preventing CVD, further high-quality trials would be valuable. However, because these trials are very difficult and resource demanding, they should be complemented by innovative observational studies that seek to strengthen causal inference through addressing sources of bias and confounding that are often incompletely accounted for in conventional observational studies. This could include a variety of methodologies, such as utilizing negative control outcomes, instrumental variables, sibling comparisons, and other genetically informed designs. As the aging population continues to grow, it becomes increasingly important to take these scientific steps in order to provide a more definitive answer to the question of the extent to which physical activity alone can reduce the risk of CVD.

User perceptions of eHealth and mHealth services promoting physical activity and healthy diets : Systematic review
- 2022

Forskningsöversikt (refereegranskat)abstract
- BACKGROUND: Physical activity and a diet that follows general recommendations can help to prevent noncommunicable diseases. However, most adults do not meet current recommended guidelines, and support for behavior change needs to be strengthened. There is growing evidence that shows the benefits of eHealth and mobile health (mHealth) services in promoting healthy habits; however, their long-term effectiveness is uncertain because of nonadherence.OBJECTIVE: We aimed to explore users' perceptions of acceptability, engagement, and usability of eHealth and mHealth services that promote physical activity, healthy diets, or both in the primary or secondary prevention of noncommunicable diseases.METHODS: We conducted a systematic review with a narrative synthesis. We performed the literature search in PubMed, PsycINFO, and CINAHL electronic databases in February 2021 and July 2021. The search was limited to papers published in English between 2016 and 2021. Papers on qualitative and mixed method studies that encompassed eHealth and mHealth services for adults with a focus on physical activity, healthy diet, or both in the primary or secondary prevention of noncommunicable diseases were included. Three authors screened the studies independently, and 2 of the authors separately performed thematic analysis of qualitative data.RESULTS: With an initial finding of 6308 articles and the removal of 427 duplicates, 23 articles were deemed eligible for inclusion in the review. Based on users' preferences, an overarching theme-eHealth and mHealth services provide value but need to be tailored to individual needs-and 5 subthemes-interactive and integrated; varying and multifunctional; easy, pedagogic, and attractive; individualized and customizable; and reliable-emerged.CONCLUSIONS: New evidence on the optimization of digital services that promote physical activity and healthy diets has been synthesized. The findings represent users' perceptions of acceptability, engagement, and usability of eHealth and mHealth services and show that services should be personalized, dynamic, easily manageable, and reliable. These findings can help improve adherence to digital health-promoting services.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Measuring physical activity and sedentary behavior accurately remains a challenge. When describing the uncertainty of mean values or when making group comparisons, minimising Standard Error of the Mean (SEM) is important. The sample size and the number of repeated observations within each subject influence the size of the SEM. In this study we have investigated how different combinations of sample sizes and repeated observations influence the magnitude of the SEM.METHODS: A convenience sample were asked to wear an accelerometer for 28 consecutive days. Based on the within and between subject variances the SEM for the different combinations of sample sizes and number of monitored days was calculated.RESULTS: Fifty subjects (67% women, mean ± SD age 41 ± 19 years) were included. The analyses showed, independent of which intensity level of physical activity or how measurement protocol was designed, that the largest reductions in SEM was seen as the sample size were increased. The same magnitude in reductions to SEM was not seen for increasing the number of repeated measurement days within each subject.CONCLUSION: The most effective way of reducing the SEM is to have a large sample size rather than a long observation period within each individual. Even though the importance of reducing the SEM to increase the power of detecting differences between groups is well-known it is seldom considered when developing appropriate protocols for accelerometer based research. Therefore the results presented herein serves to highlight this fact and have the potential to stimulate debate and challenge current best practice recommendations of accelerometer based physical activity research.

- BackgroundThis study examines the relationship of neighbourhood environment factors with walking and total health enhancing physical activity.MethodsA population-based cross-sectional study. The short self-administered version of the validated International Physical Activity Questionnaire (IPAQ) was used to assess health enhancing physical activity including walking. The neighbourhood environment was assessed using a 17-item environmental module. A principal component analysis among the environmental variables was conducted. The factor scores were divided into tertiles and independent associations between factor tertiles and physical activity categories and walking were studied by multinomial logistic regression with adjustment for confounders.ResultsIn adjusted models, a lower odds ratio (OR) for reaching the middle, OR: 0.66 (95% Confidence Interval (CI): 0.47–0.98), and upper, OR: 0.65 (0.45–0.95), tertile of walking was observed among those in the lowest tertile of the degree of urbanisation. A higher OR for reaching the middle, OR: 1.84 (1.28–1.64), and upper tertile, OR: 1.64 (1.14–2.36), of walking was observed among those in the lowest tertile of fear of crime. A higher OR for reaching the high category of total health enhancing physical activity was observed among those in the lowest, OR: 2.01 (1.32–3.05), and middle tertile, OR: 1.52 (1.02–2.25), of the factor degree of urbanisation.ConclusionThe findings suggest that the environment is differentially related to walking and total health enhancing physical activity. This should be explored in future research to disentangle the complex relationship between different levels and aspects of physical activity and their relationship with the environment.

- BACKGROUND: To increase the knowledge about physical activity (PA) patterns and correlates among children under the age of 4, there is a need for study's using objective measurements. The aim of this study was therefore to investigate if objectively measured PA among 3-year-old children differed between day of week and time of day and whether it correlated to child weight status and sex as well as parental weight status and education.METHODS: Totally 61 children (51% girls) aged 3, participating in Early Stockholm Obesity Prevention Project were included. PA was measured with a tri-axial accelerometer (ActiGraph GT3X+) worn on the non-dominant wrist for one week. The main outcome was average PA expressed as counts per minute from the vector magnitude. PA and demographics/family-related factors were collected at baseline and at age 3. To analyze the results simple linear regression, ANOVA and paired t-tests were performed.RESULTS: The mean number of valid days was 6.7 per child. The children were more active on weekdays than weekends (p < 0.01) and the hourly pattern differed over the day with children being most active midmorning and midafternoon (p = 0.0001). Children to parents with low education were more active (p = 0.01) than those with highly educated parents. No differences in PA by child weight status, sex nor parental weight status were found.CONCLUSIONS: PA in 3-year-old children was lower during weekends than weekdays and varied over the day. Boys and girls had similar PA patterns, these patterns were independent of child or parental weight status. Children to parents with low education were more active than their counterparts. The fact that PA differed between weekdays and weekends indicates that PA might be affectable in 3-year-old children.

- OBJECTIVE: To examine the joint associations of daily time spent in different intensities of physical activity, sedentary behaviour and sleep with all-cause mortality.METHODS: Federated pooled analysis of six prospective cohorts with device-measured time spent in different intensities of physical activity, sedentary behaviour and sleep following a standardised compositional Cox regression analysis.PARTICIPANTS: 130 239 people from general population samples of adults (average age 54 years) from the UK, USA and Sweden.MAIN OUTCOME: All-cause mortality (follow-up 4.3-14.5 years).RESULTS: Studies using wrist and hip accelerometer provided statistically different results (I2=92.2%, Q-test p<0.001). There was no association between duration of sleep and all-cause mortality, HR=0.96 (95% CI 0.67 to 1.12). The proportion of time spent in moderate to vigorous physical activity was significantly associated with lower risk of all-cause mortality (HR=0.63 (95% CI 0.55 to 0.71) wrist; HR=0.93 (95% CI 0.87 to 0.98) hip). A significant association for the ratio of time spent in light physical activity and sedentary time was only found in hip accelerometer-based studies (HR=0.5, 95% CI 0.42 to 0.62). In studies based on hip accelerometer, the association between moderate to vigorous physical activity and mortality was modified by the balance of time spent in light physical activity and sedentary time.CONCLUSION: This federated analysis shows a joint dose-response association between the daily balance of time spent in physical activity of different intensities and sedentary behaviour with all-cause mortality, while sleep duration does not appear to be significant. The strongest association is with time spent in moderate to vigorous physical activity, but it is modified by the balance of time spent in light physical activity relative to sedentary behaviour.

- Objective To test whether youths who engage in vigorous physical activity are more likely to have lean bodies while ingesting relatively large amounts of energy. For this purpose, we studied the associations of both physical activity and adiposity with energy intake in adolescents.Study design The study subjects were adolescents who participated in 1 of 2 cross-sectional studies, the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study (n = 1450; mean age, 14.6 years) or the European Youth Heart Study (EYHS; n = 321; mean age, 15.6 years). Physical activity was measured by accelerometry, and energy intake was measured by 24-hour recall. In the HELENA study, body composition was assessed by 2 or more of the following methods: skinfold thickness, bioelectrical impedance analysis, plus dual-energy X-ray absorptiometry or air-displacement plethysmography in a subsample. In the EYHS, body composition was assessed by skinfold thickness.Results Fat mass was inversely associated with energy intake in both studies and using 4 different measurement methods (P <=.006). Overall, fat-free mass was positively associated with energy intake in both studies, yet the results were not consistent across measurement methods in the HELENA study. Vigorous physical activity in the HELENA study (P<.05) and moderate physical activity in the EYHS (P<.01) were positively associated with energy intake. Overall, results remained unchanged after adjustment for potential confounding factors, after mutual adjustment among the main exposures (physical activity and fat mass), and after the elimination of obese subjects, who might tend to under-report energy intake, from the analyses.Conclusion Our data are consistent with the hypothesis that more physically active and leaner adolescents have higher energy intake than less active adolescents with larger amounts of fat mass.

Tidskriftsartikel (refereegranskat)abstract
- Background: Increasing empirical evidence supports associations between neighborhood environments and physical activity. However, since most studies were conducted in a single country, particularly western countries, the generalizability of associations in an international setting is not well understood. The current study examined whether associations between perceived attributes of neighborhood environments and physical activity differed by country. Methods: Population representative samples from 11 countries on five continents were surveyed using comparable methodologies and measurement instruments. Neighborhood environment x country interactions were tested in logistic regression models with meeting physical activity recommendations as the outcome, adjusted for demographic characteristics. Country-specific associations were reported. Results: Significant neighborhood environment attribute x country interactions implied some differences across countries in the association of each neighborhood attribute with meeting physical activity recommendations. Across the 11 countries, land-use mix and sidewalks had the most consistent associations with physical activity. Access to public transit, bicycle facilities, and low-cost recreation facilities had some associations with physical activity, but with less consistency across countries. There was little evidence supporting the associations of residential density and crime-related safety with physical activity in most countries. Conclusion: There is evidence of generalizability for the associations of land use mix, and presence of sidewalks with physical activity. Associations of other neighborhood characteristics with physical activity tended to differ by country. Future studies should include objective measures of neighborhood environments, compare psychometric properties of reports across countries, and use better specified models to further understand the similarities and differences in associations across countries.

- BACKGROUND: Associations of objectively assessed physical activity in different intensities and risk of developing chronic disease that requires hospital care have not yet been examined in long term population-based studies. Studies addressing the link between physical activity and sedentary time and subsequent hospital admissions are lacking.OBJECTIVE: To examine the prospective associations between physical activity and sedentary time with morbidity defined as: 1) a registered main diagnosis of cardiovascular disease, cancer, type-2 diabetes, dementia, obesity or depression; 2) number of in- and outpatient hospital visits; and 3) number of in-hospital days.METHODS: In total, 1220 women and men, 18-75 years, from the population-based Sweden Attitude Behaviour and Change study 2000-2001 were included. Time spent sedentary, in light-intensity physical activity and in moderate-to-vigorous physical activity, and total accelerometer counts were assessed using the ActiGraph 7164 accelerometer. Morbidity data were obtained 2016 from Swedish registers. Cox proportional hazards models estimated hazard ratios (HR) of morbidity with 95% confidence intervals (CI) and negative binomial regression estimated incidence rate ratio (IRR) with 95% CI for number of hospital visits, and length of hospital stay.RESULTS: Over a follow-up of 14.4 years (SD = 1.6), 342 persons had at least one registered hospital visit due to any of the included diagnoses. Higher moderate-to-vigorous physical activity was associated with significant risk reductions for combined morbidity (all included diagnoses) (HR: 0.65, 95% CI: 0.48-0.88) and cardiovascular disease (HR: 0.52, 95% CI: 0.33-0.82). Higher total counts showed similar results, and was also associated with fewer hospital visits (IRR = 0.56, 95% CI: 0.37-0.85). Higher sedentary time increased the risk of in-hospital days. (IRR = 2.38, 95% CI: 1.20-4.74).CONCLUSION: This study supports the importance of moderate-to-vigorous physical activity for preventing chronic disease that requires hospital care, especially cardiovascular disease. High volumes of sedentary behavior may increase the risk of future hospitalization. Our results support the public health message "sit less and move more".

- OBJECTIVETo examine the dose-response associations between accelerometer assessed total physical activity, different intensities of physical activity, and sedentary time and all cause mortality.DESIGNSystematic review and harmonised meta-analysis.DATA SOURCESPubMed, PsycINFO, Embase, Web of Science, Sport Discus from inception to 31 July 2018.ELIGIBILITY CRITERIAProspective cohort studies assessing physical activity and sedentary time by accelerometry and associations with all cause mortality and reported effect estimates as hazard ratios, odds ratios, or relative risks with 95% confidence intervals.DATA EXTRACTION AND ANALYSISGuidelines for meta-analyses and systematic reviews for observational studies and PRISMA guidelines were followed. Two authors independently screened the titles and abstracts. One author performed a full text review and another extracted the data. Two authors independently assessed the risk of bias. Individual level participant data were harmonised and analysed at study level. Data on physical activity were categorised by quarters at study level, and study specific associations with all cause mortality were analysed using Cox proportional hazards regression analyses. Study specific results were summarised using random effects meta-analysis.MAIN OUTCOME MEASUREAll cause mortality.RESULTS39 studies were retrieved for full text review; 10 were eligible for inclusion, three were excluded owing to harmonisation challenges (eg, wrist placement of the accelerometer), and one study did not participate. Two additional studies with unpublished mortality data were also included. Thus, individual level data from eight studies (n=36 383; mean age 62.6 years; 72.8% women), with median follow-up of 5.8 years (range 3.0-14.5 years) and 2149 (5.9%) deaths were analysed. Any physical activity, regardless of intensity, was associated with lower risk of mortality, with a non-linear dose-response. Hazards ratios for mortality were 1.00 (referent) in the first quarter (least active), 0.48 (95% confidence interval 0.43 to 0.54) in the second quarter, 0.34 (0.26 to 0.45) in the third quarter, and 0.27 (0.23 to 0.32) in the fourth quarter (most active). Corresponding hazards ratios for light physical activity were 1.00, 0.60 (0.54 to 0.68), 0.44 (0.38 to 0.51), and 0.38 (0.28 to 0.51), and for moderate-to-vigorous physical activity were 1.00, 0.64 (0.55 to 0.74), 0.55 (0.40 to 0.74), and 0.52 (0.43 to 0.61). For sedentary time, hazards ratios were 1.00 (referent; least sedentary), 1.28 (1.09 to 1.51), 1.71 (1.36 to 2.15), and 2.63 (1.94 to 3.56).CONCLUSIONHigher levels of total physical activity, at any intensity, and less time spent sedentary, are associated with substantially reduced risk for premature mortality, with evidence of a non-linear dose-response pattern in middle aged and older adults.

Active school transportation : Understanding the parental decision-making process
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. In efforts to reverse the current trend, active school transportation (AST) and independent mobility (IM) have been suggested as opportunities to increase levels of physical activity. Unfortunately, AST and IM have decreased during recent decades; consequently, initiatives promoting such behaviors have been called for. Parents are the main decision-makers on a child’s use of AST and IM, and thus, understanding their decisions is important in efforts to promote such behaviors. The overarching aim of this thesis was to increase the understanding of the parental decision-making process concerning their children’s active transport to school.This thesis applied an exploratory sequential design, with both interview (qualitative) and cross-sectional (quantitative) designs used to attain the overall aim. Data was collected through interviews with 20 parents (I) and two surveys: the PILCAST (Parents intentions to let their child use AST) questionnaire (II-III) and the PACO (Pedalea y Anda COlegio [Cycle and walk to school]) family questionnaire (IV). In total, 1024 responses from parents were collected with the PILCAST questionnaire (II). In paper III, a sub-sample of 610 was extracted from the 1024, based on parents responding “yes” or “no” to participation in an AST intervention. In paper IV, a total of 573 parents were included in the study. Data was analyzed with content analysis (I), descriptive statistics (II-IV), confirmatory factor analysis (II), linear regression analysis (II-IV), and logistic regression analysis (IV).The main findings showed that parents’ decisions regarding AST and IM were influenced by social norms, which was reflected in appearing to be a good parent and by what significant others do in their vicinity and neighborhood (I, II, IV). The importance of social norms applied to both Swedish and Spanish parents when it comes to AST. Some, gender differences were found, showing that they might play a more important role for parents of girls when it comes to AST and IM. Further, the findings showed that attitudes influence decisions, which was reflected in how parents master everyday life by sometimes choosing what is most convenient, even though they are aware of the benefits of AST (I-II). Parents identified factors both impeding and facilitating the use of AST, while safety and trusting the child were found to be important (I-II). The findings also indicate that the intervention within the Sustainable Innovation for Children Transporting Actively (SICTA) project might positively influence parents’ beliefs about AST (III). In addition, there seems to be a habitual factor involved in the parental decision-making process (II). Differences were found between parents’ decisions to let their child cycle to school compared to letting their child walk to school (II). Finally, the parental decision-making process seems to be influenced by the child’s age and the distance between home and school (I, II, IV). The PILCAST questionnaire showed acceptable validity and reliability.In conclusion, the findings show that when aiming to promote AST and IM, social acceptance is important. This concerns both other people’s judgments of parenting and what other important referent groups are doing, encompassing the visibility of AST and IM in the parents’ vicinity and neighborhoods. Attention given to gender differences could be beneficial as well. Further, it is also important to understand the prerequisites of modern family life. It is likely that strengthening positive attitudes in parents could promote AST, but the practice also needs to be in line with their everyday life tasks. Efforts should also be made to strengthen the factors that facilitate AST. From a parental perspective, this includes safety and being supported in gaining trust in their children and their children’s capabilities with respect to the age of the children. Habit seems to play an important role, and to encourage parents to form new habits, it might be beneficial to launch AST interventions along with contextual changes, as these might open a window for change, which could occur in the transition between preschool and primary school. It could be beneficial to consider cycling and walking as different behaviors because walking seems to be more dependent on the distance to school than cycling. Further, the PILCAST questionnaire was valid and reliable, providing an increased understanding of these behaviors from a parental perspective. Finally, to make children’s use of active transport to school the more favorable choice, it seems worthwhile not only to give children the opportunity to participate but also to involve parents and address their beliefs when designing interventions.

Tidskriftsartikel (refereegranskat)abstract
- Background: Parkinson's disease (PD) affects many physiological systems essential for balance control. Recent studies suggest that intensive and cognitively demanding physical exercise programs are capable of inducing plastic brain changes in PD. We have developed a highly challenging balance training (the HiBalance) program that emphasizes critical aspects of balance control through progressively introducing more challenging exercises which incorporates dual-tasking. Earlier studies have shown it to be effective in improving balance, gait and dual-tasking. The study design has thereafter been adjusted to link intervention-induced behavioral changes to brain morphology and function. Specifically, in this randomized controlled trial, we will determine the effects of the HiBalance program on balance, gait and cognition and relate this to task-evoked functional MRI (fMRI), as well as brain-derived neurotrophic factor (BDNF) in participants with mild-moderate PD.Methods: One hundred participants with idiopathic PD, Hoehn & Yahr stage 2 or 3, >= 60 years of age, >= 21 on Montreal Cognitive Assessment will be recruited in successive waves and randomized into either the HiBalance program or to an active control group (the HiCommunication program, targeting speech and communication). Both interventions will be performed in small groups, twice a week with 1 h sessions for 10 weeks. In addition, a 1 h, once a week, home exercise program will also be performed. A double-blinded design will be used. At the pre- and post-assessments, participants will be assessed on balance (main outcome), gait, cognitive functions, physical activity, voice/speech function, BDNF in serum and fMRI (3 T Philips) during performance of motor-cognitive tasks.Discussion: Since there is currently no cure for PD, findings of neuroplastic brain changes in response to exercise would revolutionize the way we treat PD, and, in turn, provide new hope to patients for a life with better health, greater independence and improved quality of life.

- This report aims (1) to examine the association between seasonality and physical activity (PA) and sedentary time in European adolescents and (2) to investigate whether this association was influenced by geographical location (Central-North versus South of Europe), which implies more or less extreme weather and daylight hours. Valid data on PA, sedentary time and seasonality were obtained in 2173 adolescents (1175 females; 12.5-17.5 years) included in this study. Physical activity and sedentary time were measured by accelerometers. ANCOVA was conducted to analyse the differences in PA and sedentary time across seasons. Results showed that girls had lower levels of moderate to vigorous PA (MVPA) and average PA, and spent more time in sedentary activities in winter compared with spring (all P < 0.05). Stratified analyses showed differences in PA and sedentary time between winter and spring in European girls from Central-North of Europe (P < 0.05 for sedentary time). There were no differences between PA and sedentary time across seasonality in boys. In conclusion, winter is related with less time spent in MVPA, lower average PA and higher time spent in sedentary activities in European adolescent girls, compared with spring. These differences seem to mainly occur in Central-North Europe.

A holistic approach in measuring occupational physical activity : challenges and potentials
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Considering that adults spend a considerable proportion of their day at work, employment is a key determinant for daily PA. However, specifics of how and under what circumstances occupational PA (OPA) influences total PA, including other PA domains (e.g. leisure time PA, transport), are unclear. Little is also known about OPA patterns in different occupational groups and how OPA patterns can be changed, among for example those who have mostly sedentary occupations. One important issue concerns if working in a standing position and the use of dynamic chairs has any effect on OPA levels, for instance among office workers. This despite the fact that ergonomists advocate sedentary workers to work in a standing position or use an “active sitting” approach using “dynamic” chairs. To be able to give recommendations regarding PA to employees with different OPA, more insight is needed on how to optimally measure OPA. To move the field forward, knowledge should be combined from different disciplines involved in measuring OPA. Therefore, we want to initiate an interdisciplinary discussion on appropriate measurements of OPA. The aim of the symposium is to present a holistic approach to measuring OPA by combining our expertise in the field of PA and health, measurement of PA using objective measures and self-reported measures, ergonomics, occupational health and public health science.

Assessment of health-enhancing physical activity at population level
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- To assess the levels and patterns of health-enhancing physical activity in the population there is a real need for better instruments to be developed. The overall aims of this thesis were to test the International Physical Activity Questionnaire (IPAQ) and to study the level of health-enhancing physical activity in the Swedish adult population using both the IPAQ (a subjective method) and accelerometry (an objective method). To validate the IPAQ, data was collected from a convenience sample of 46 adult men and women. In a second study data was collected from 980 men and women, aged 18 - 65, randomly chosen from a population register. The IPAQ data was compared against data from an accelerometer and a logbook for concurrent validity, and body composition and aerobic fitness for construct validity. For the population based studies two nationally representative samples of adult men and women were used (N = 1,470 and N = 1,114). The validation studies showed significant correlations between the IPAQ and the accelerometer and logbook, although large intra-individual differences were found. Vigorous intensity activity and time spent in inactivity were systematically overreported with IPAQ. The IPAQ data showed that adults reported a median (25th - 75th percentile) of 1,699 (693 - 3,600) MET-min.week-1. This corresponds to about 60 (24 - 128) minutes of brisk walking per day. Men reported significantly more activity than women (1,836 vs. 1,554 MET-min.week-1, P < 0.001). A significant difference in total physical activity was found across age, BMI and self-rated health categories. For men, walking contributed 35 % (11 - 73 %) of the total physical activity, while for women, walking contributed 45 % (22 - 92 %). The accelerometer data showed that men were significantly more active on moderate or higher intensity level than women. For total physical activity and time spent in inactivity, neither gender, age nor BMI could explain the variance. More than half (52 %) of the study population reached the 30 minutes per day recommendation when every minute at moderate or higher intensity was counted. When activity bouts of 10 minutes or longer were considered, the prevalence estimates were only one percent. This is the first time levels and patterns of physical activity have been assessed at population level, using objective methodology. Even though the absolute values between the instruments used differed, they both provided qualitatively consistent pictures. This thesis has shown a new and sobering picture of health-enhancing physical activity at population level. At the same time, the need to better understand the nature and measurement issues of health-enhancing physical activity has been highlighted.

Tidskriftsartikel (refereegranskat)abstract
- To make individualized counseling possible, valid and reliable measures of physical activity are necessary. In health care, quality must be continuously secured and developed. Follow-up of life-style habits such as physical activity does not differ from monitoring of other treatment in the health care setting. After counseling and appropriate period of time, evaluation should be done to assess if there has been any change in the physical activity level. For assessment and evaluation of physical activity in routine clinical practice the National Board for Health and Social Welfare indicator questions regarding physical activity are recommended. For a more detailed assessment and evaluation of physical activity and sedentary behavior comprehensive validated instruments/diaries should be used. For precise and objective assessment and evaluation of both physical activity and sedentary behavior, movement sensors are recommended.
