Beyond the big five: a 10-year longitudinal study of personality traits predicting leisure-time physical activity among adults

ABSTRACT The purpose of this study was to compare and contrast the Big Five model of personality with Tellegen’s Multidimensional Personality Questionnaire (MPQ) to investigate how they predict light intensity, moderate intensity and vigorous intensity leisure-time physical activity (LTPA) using population-based secondary longitudinal data. The Tellegen facet harm avoidance predicted a decrease in moderate and vigorous LTPA. From the Big Five, extraversion predicted increased moderate and vigorous LTPA and, additionally, openness predicted increased vigorous LTPA. This comparison reveals the complementary nature of both personality models to better understand how multiple aspects of personality predict LTPA and shows that leisure studies scholars may want to consider alternatives to the Big Five when considering intrapersonal predictors of physically active leisure.

NHANES-based analysis of the correlation between leisure-time physical activity, serum cotinine levels and periodontitis risk

ObjectiveTo investigate the association of leisure-time physical activity and serum cotinine levels with the risk of periodontitis in the general population and to further analyze the interaction between leisure-time physical activity and serum cotinine levels on the risk of periodontitis.MethodsThis was a cross-sectional study, extracting data from 9605 (56.19%) participants in the National Health and Nutrition Examination Survey (NHANES) database from 2009 to 2014, and analyzing the relationship and interaction effects of serum cotinine level, leisure time physical activity, and risk of periodontitis by weighted univariate logistic modeling; Effect sizes were determined using ratio of ratios (OR), 95% confidence intervals (95% CI).Results5,397 (56.19%) of 9,605 participants had periodontitis; an increased risk of periodontitis was found in those in the leisure time physical activity intensity < 750 MET × min/week group (OR = 1.44, 95% CI: 1.17–1.78). Serum cotinine levels ≥ 0.05 ng/ml were associated with an increased risk of periodontitis (OR = 1.99, 95% CI: 1.69–2.33). The group with low leisure physical activity and serum cotinine levels ≥ 0.05 ng/ml had an increased risk of periodontitis compared to the group with high leisure physical activity and serum cotinine levels < 0.05 ng/ml (OR = 2.48, 95% CI: 1.88–3.27). Interaction metrics RERI = 0.90 (95% CI: 0.44–1.36) and API = 0.36 (95% CI: 0.18–0.55); CI for SI = 2.55 (95% CI: 1.03–6.28). for API 0.36.ConclusionLeisure time physical activity intensity interacted with smoking exposure on periodontitis risk and may provide the general population with the opportunity to Increasing leisure-time physical activity and smoking cessation may provide recommendations for the general population.

Norwegian Outdoor Happiness: Residential Outdoor Spaces and Active Leisure Time Contributions to Subjective Well-being at the National Population Level at the Start of and During the COVID-19 Pandemic

Accumulating research shows that residential nature reliably promotes residents’ subjective well-being (SWB) in complex ways. The present study investigates how self-reported proximity to different outdoor spaces relate to SWB in Norway. The effects of having proximity to recreation and hiking areas and the frequency of moderate-to-vigorous intensity leisure-time physical activity (MVLTPA) were estimated for five SWB measures (satisfaction with life, positive, and negative affect, mental well-being, and meaning in life). The study also estimated how outdoor spaces promote MVLTPA, and which of these relationships changed during the COVID-19 pandemic. Two Norwegian samples (collected in 2020 and 2021; N = 34,904) were explored using multiple linear and multinomial logistic regression analyses. Residential outdoor spaces predicted higher SWB across measures and MVLTPA frequency. Importantly, an inverted U-shaped relationship between MVLTPA and all SWB measures was found, with a tipping point coinciding with weekly MVLTPA. Last, during the pandemic, outdoor spaces became stronger predictors: hiking areas for mental well-being and meaning in life; and recreation areas for MVLTPA (p < .05). This study refines our understanding of these complex relations and contributes to setting these effects in perspective with other sociodemographic factors and SWB measures. Lastly, the importance of residential outdoor spaces upon the prospect of future pandemics is discussed.

Multidimensionality of leisure-time physical activity behaviour in adults with spinal cord injury: implications for measurement.

The Physical Activity Recall Assessment for People with SCI (PARA-SCI) has demonstrated the best test-retest reliability and validity of self-report measures of leisure-time physical activity (LTPA) for adults with SCI. However, the absence of internal consistency reliability data has been raised as a concern. Internal consistency is relevant only for unidimensional measures. In other populations, LTPA is known to be a multidimensional construct, evaluated with multidimensional measures. We tested for unidimensionality through secondary analysis of PARA-SCI data (n = 703). Cronbach's α was 0.227. Principal components analysis showed two components/dimensions ('Moderate and Heavy Intensity LTPA' and 'Mild Intensity LTPA') explained 73% of the variance. Binary logic crosstabulation produced no discernible patterns of behavioural interrelatedness across LTPA intensities. Together, these data demonstrate the multidimensionality of LTPA and the PARA-SCI is not unidimensional. Internal consistency should not be a criterion for evaluating LTPA questionnaires for use in studies of people with SCI.

Baseline Comparison of Exercisers and Nonexercisers With Spinal Cord Injury Enrolled in a Group Tele-Exercise Program.

Individuals with SCI are 1.5 times more likely to be sedentary compared to adults without disabilities or chronic health conditions. It is therefore imperative to develop and evaluate innovative facilitation strategies for physical activity behavior in this population. As an insightful step to creating and evaluating tailored physical activity interventions for individuals with SCI, we evaluated demographic, psychosocial, and physical characteristics of those who choose to engage in physical activity by enrolling in a group exercise study. We conducted a cross-sectional analysis detailing demographic features and baseline outcomes of those with SCI enrolled in a group tele-exercise study who were classified as regular exercisers versus nonregular exercisers per the American College of Sports Medicine exercise guidelines. Between-group differences for psychosocial and physical outcomes were assessed with chi-square and Mann-Whitney U tests (p < .05). Twenty-seven adult volunteers enrolled in the study (exercisers = 14, nonexercisers = 13). Groups were comparable for biological sex, gender identity, self-reported racial group(s), and current age. Exercisers demonstrated significantly shorter duration of injury compared to nonexercisers (p = .012). Exercisers exhibited significantly higher exercise self-efficacy (p = .017) and increased reported weekly minutes in vigorous intensity leisure time physical activity (p = .029). Nonexercisers with SCI demonstrate increased injury duration and reduced exercise self-efficacy compared to active peers. These factors should be addressed in the design and delivery of SCI-specific physical activity interventions to increase the likelihood of this critical health behavior over time.

O.4.5-2 Participation in organized and unorganized sports in adolescence: associations with physical activity levels in adulthood

Abstract Purpose Participation in organized youth sports (OYS) has been linked to higher levels of physical activity (PA) in adulthood. However, the longitudinal associations of OYS and PA compared to unorganized sports and non-participation have not been extensively studied. This study aims to explore the associations of both organized and unorganized sports in adolescence with PA levels in midlife. Methods Participants in this study were drawn from the on-going, population-based prospective Young Finns Study. Data from follow-ups conducted in the years 1980, 1983, 1986, and 1989 were utilized to divide the participants into groups of active OYS, active unorganized sports, and non-participants, separately at the ages of 9 (n = 548), 12 (n = 727), 15 (n = 752), and 18 (n = 767). The groups were formed according to self-reported frequency and intensity of leisure time PA and participation in sports club activities in adolescence. Accelerometer-derived PA (mean daily minutes of sedentary time [ST], light-intensity PA [LPA], and moderate-to-vigorous PA [MVPA]) in midlife was assessed in 2018-2020. Differences in adult PA between the youth PA groups were analyzed using analysis of covariance, separately in males and females. Results Compared to non-participants, boys who actively participated in OYS at age 9 had lower ST (mean difference [SE]: -38 [15], p = 0.045) and higher LPA (29 [12], p = 0.050) in midlife. No significant group differences were observed for girls at age 9 or for either sex at age 12 or 15, or for boys at age 18. In girls at age 18, significant group differences were found in MVPA in midlife in favor of both organized and unorganized sports compared to non-participants (15 [3], p &amp;lt; 0.001; 8 [3], p = 0.014, respectively). Conclusions Active participation in organized sports in boys at age 9 and active participation in both organized and unorganized sports in girls at age 18 associated with higher levels of physical activity in midlife. These findings suggest that promoting both types of sports participation in adolescence may contribute to the development of a physically active lifestyle across the life course.

Impact of upper-body ergometer rowing exercise on aerobic fitness and cardiometabolic disease risk in individuals with spinal cord injury: A 6-month follow-up study

Objective We recently demonstrated that upper-body rowing exercise (UBROW) improved aerobic fitness in individuals with spinal cord injury (SCI), with no effect on traditional cardiometabolic risk factors. Here, we tested the hypothesis that the exercise-induced increase in aerobic fitness was maintained at 6-month (6M) follow-up. Design Six-month follow-up. Setting University/hospital. Participants Seventeen wheelchair-dependent participants with SCI. Interventions 12-week of exercise training (UBROW) or control (CON). Outcome Measures Aerobic fitness (POpeak and V̇O2peak), body composition, blood pressure, and blood biomarkers of cardiometabolic risk were assessed at 6M follow-up and compared to baseline (BL) and immediately post-intervention (12-week). Minutes of mild, moderate, and heavy intensity leisure time physical activity (LTPA) were assessed by self-report. Results Fourteen participants returned at 6M follow-up (CON, n = 6; UBROW, n = 8). In UBROW, POpeak (median (Q1-Q3)) increased from BL (70 W (37–84)) to 12-week (77 W (58–109), P = 0.01) and 6M follow-up (81 W (51–96), P = 0.01), with no difference between 12-week and 6M follow-up (P = 0.21). Similarly, V̇O2peak increased from BL (15.4 ml/kg/min (10.5–19.4)) to 12-week (16.6 ml/kg/min (12.8–21.3), P = 0.01) with no difference between 12-week and 6M follow-up (16.3 ml/kg/min (12.9–19.7), P = 0.74). No differences were found in CON for either POpeak (P = 0.22) or V̇O2peak (P = 0.27). There were no changes over time in traditional cardiometabolic risk factors or for minutes of different LTPA intensities. Conclusion We demonstrate that improvements in aerobic fitness are maintained for at least six months after completion of a 12-week exercise intervention, supporting the use of periodic exercise interventions to boost aerobic fitness level in individuals with SCI.

Leisure time physical activity among older adults in Brazil: a time series analysis of a population-based survey (2009-2020).

The practice of leisure time physical activity brings several health benefits, such as the prevention of noncommunicable diseases. Investigating the temporal trend of physical activity practice in older adults by sociodemographic characteristics and geographical regions could be important to plan public health policies and effective interventions. This is a time series study that analyzes the temporal trend of leisure time physical activity among Brazilian older adults with data from 2009 to 2020. For this, we used a sample of 186,097 older adults (≥ 60 years old) obtained from the Risk and Protective Factors Surveillance System for Chronic Noncomunicable Diseases Through Telephone Interview (Vigitel) (2009-2020). Information on leisure time physical activity and sociodemographic and health characteristics were collected. Prais-Winsten regression was used to identify significant trends in the annual variation of the leisure time physical activity indicators. Practice of ≥ 150 minutes/week of moderate intensity leisure time physical activity varied from 23.3% to 27.5% (0.41p.p./year) (2009-2020), with a higher increase during 2015-2020 (0.59p.p./year). The increase in the most recent period occurred among men, aged from 60 to 69 years, with lower educational level, residing in the Northeast Region, and without self-reported chronic diseases. These results may contribute to the evaluation of Brazilian health policies targeting the leisure time physical activity practice in older adults.

Leisure-Time Physical Activity in People With Spinal Cord Injury-Predictors of Exercise Guideline Adherence.

Objectives: This study described leisure-time physical activity (LTPA) for people in Australia with spinal cord injury (SCI) and whether certain sociodemographic and psychosocial variables might be associated with LTPA uptake and guidelines adherence. Methods: The Physical Activity Scale for Individuals with a Physical Disability was used to measure the intensity and volume of LTPA of 1,579 individuals with SCI. Summary statistics were calculated for LTPA guidelines adherence. Analyses included regression modelling. Results: Of the 1,579 participants, 58% performed LTPA and 13% adhered to recommended guidelines for weekly LTPA. There was an association with being an "exerciser" based on the time since injury (OR = 1.02 [95% 1.01-1.03]), a traumatic injury (OR = 1.53 [95% CI 1.13-2.08]) and a higher self-rating of health (OR = 1.10 [95% CI 0.95-1.27]). Where LTPA guidelines were met, adherence was most related to a traumatic injury (OR = 1.75 [95% CI 1.02-3.02]) and being unemployed (OR = 1.53 [95% CI 1.03-2.25]). Conclusion: Of those who performed LTPA with SCI, one in four met population-specific LTPA guidelines. Sociodemographic variables were moderately associated with being an "exerciser" or LTPA "guideline-adherent."

Frequency of leisure-time physical activity and pulse pressure in the Brazilian population: a population-based study

ObjectiveThe purpose of this study was to investigate the association between the frequency of leisure-time physical activity and brachial pulse pressure (PP), according to physical activity intensity and type, sex, and age, in the general Brazilian population. Study designThis was a cross-sectional study based on data from the Brazilian 2013 National Health Survey. MethodsThe sample consisted of 20,058 men and 20,600 women aged between 18 and 65 years. The frequency of leisure-time physical activity was obtained through a questionnaire and classified according to intensity (vigorous or moderate) and type (cyclic or acyclic). We calculated PP as the difference between systolic and diastolic blood pressures based on the measure of a digital pressure device. Multiple linear regression analysis was applied to analyze the association of different sexes, frequency, type, and intensity of leisure-time physical activity and PP. ResultsAdjusted results showed that one session of moderate physical activity per week could benefit men's PP: β = −1.87 mmHg; SE = 0.83. For women, the adjusted model reveals that physical activity undertaken twice a week is sufficient to benefit PP: β = −1.77 mmHg; SE = 0.72. However, according to type, two times a week of acyclic activities increased PP in men: β = 2.62 mmHg; SE = 0.62 and decreased in women: β = −2.67 mmHg; SE = 0.72. ConclusionsOur results suggest that low frequencies of leisure-time physical activity are sufficient to induce beneficial effects on the cardiovascular system for both sexes. Also, there are some differences between sexes in cardiac adaptations according to type, frequency, and intensity of physical activity.

The Association between Leisure-Time Physical Activity Intensity and Duration with the Risk of Mortality in Patients with Chronic Kidney Disease with or without Cardiovascular Diseases.

For chronic kidney disease (CKD) patients with or without cardiovascular diseases, the associations between leisure-time physical activity intensity (LTPA) and daily exercise time with mortality risk remain unclear. This study enrolled 3279 CKD patients from National Health and Nutrition Examination Survey (NHANES) 2007-2014 survey. Patients were grouped into different groups according to LTPA intensity (none, moderate, vigorous) and duration (0 min, 0-30 min, 30-60 min, 60 min). We selected the confounders based on their connections with the outcomes of interest or a change in effect estimate of more than 10%. Multivariable-adjusted Cox proportional hazards models were used to examine the associations between LTPA and mortality. The three-knot cubic spline (10, 50, and 90%) was employed to investigate the relationship between the dose of LTPA duration and all-cause death. Patients were divided into different groups according to cardiovascular diseases (CVD). A total of 564 all-cause death were recorded in this study. Multivariable Cox regression showed that moderate LTPA was associated with a reduced risk of mortality by 38% (hazard ratio (HR): 0.62, 95% confidence interval (CI): 0.44-0.88) in CKD patients, while vigorous LTPA did not have evident survival benefits (HR: 0.91, 95% CI: 0.46-2.64). Subgroups analysis demonstrated that those who engaged in moderate LTPA have a significantly lower risk of mortality (HR: 0.67, 95% CI: 0.47-0.95) in patients without CVD, while patients complicated with CVD did not benefit from the practice (HR: 0.61, 95% CI: 0.37-1.02). Physical exercise for more than 30 minutes was associated with a lower risk of mortality in general CKD patients (30-60 min: HR: 0.23, 95% CI: 0.09-0.58, 60 min: HR: 0.23, 95% CI: 0.08-0.63) and those without CVD (30-60 min/d: HR: 0.32, 95% CI: 0.12-0.83, 60 min/d: HR: 0.20, 95% CI: 0.06-0.71); however, this positive outcome was not seen in patients complicated with CVD (30-60 min/d: HR: 0.67, 95% CI: 0.11-4.04, 60 min/d: HR: 1.14, 95% CI: 0.14-9.11). Moderate LTPA for more than 30 minutes is associated with a reduced risk of mortality in general CKD patients and those without CVD. However, LTPA did not reduce the risk of mortality in CKD patients complicated with CVD.

Social Environments and Physical Activity Among Active Black Women.

To explore the social context of physical activity (PA) among active Black women, we examine the patterns of PA engagement and the benefits of social support in PA maintenance. A cross-sectional study design and descriptive phenomenological approach were used to examine social support and lived experiences of active Black women. The study setting was an online survey of active Black women, ages 21 to 71years who were recruited from across the United States. This secondary data analysis was conducted among a sample of 187 active Black women who maintained PA for ≥6months. The mean age was 41 ± 12.3years, 83.4% completed some college, 37.7% were married, and 30.0% had children. Participants self-reported 'with whom' they engaged in PA and provided qualitative responses about their strategies for PA maintenance. Descriptive statistics were used to examine between-group differences among demographic characteristics and PA variables by category of PA engagement using SAS 9.4. Descriptive phenomenology was used to explore social support themes across and within categories of PA engagement. On average, the active Black women in this study reported engaging in 57.0 ± 18.9 minutes of moderate intensity leisure-time PA per session. Most engaged in PA alone (n = 87), with a group (n = 72), or with another individual (n = 28). Social context themes within categories included: alone - self-management, groups - motivation and accountability, family - values health, and friends - shared interests in PA. Subthemes across social context categories included: who? - people, what and how? - types of social support, and where? - place of social support. Our findings suggest that some Black women may need added social support from others beyond family and friends, while other Black women may prefer additional self-management skills. Nonetheless, this study provides data for developing hypotheses about the mechanisms by which social context may facilitate PA maintenance among Black women. Therefore, intervention studies targeting PA maintenance among Black women should include an in-depth query of social support needs.

Role of Physical Activity in Lowering Risk of End-Stage Renal Disease

ObjectiveTo investigate the association between the amount and intensity of leisure-time physical activity (LTPA) and the risk of end-stage renal disease (ESRD). MethodsThe study examined a cohort of 543,667 participants aged 20 years and older who participated in a health screening program from January 1, 1996, through December 31, 2017. We identified 2520 individuals undergoing dialysis or who had a kidney transplant by linking participants’ encrypted personal identification with the registry for ESRD with a median follow-up of 13 years. We classified participants into 5 categories measured by metabolic equivalent of tasks. Within each category, we analyzed the effect of moderate- and vigorous-intensity LTPA in reducing risk of ESRD. We used a Cox proportional hazards model to calculate hazard ratios (HRs). ResultsWe observed a dose-response relationship between LTPA and the risk of ESRD. The fully active group had a 12% lower hazard of ESRD compared with the no reported LTPA group (HR, 0.88; 95% CI, 0.80 to 0.98) adjusting for covariates including baseline estimated glomerular filtration rate and proteinuria. Within the same category of LTPA, vigorous-intensity exercise carried a 35% lower HR for ESRD compared with moderate-intensity exercise (HR, 0.65; 95% CI, 0.52 to 0.81). The effect was observed stronger among men, younger participants, and participants with diabetes or hyperlipidemia. ConclusionSustained LTPA (≥ 150 minutes per week), particularly with vigorous intensity, significantly lowered the ESRD risk, even among individuals with comorbidities such as diabetes or hyperlipidemia. This finding suggested that patients with no reported LTPA with cardiovascular risks should engage in more LTPA to lower their risk of ESRD.

Abstract MP29: Higher Levels Of Leisure Physical Activity In Mid-life And Attenuated Physical Function Declines In Late-life: The Atherosclerosis Risk In Communities Study

Introduction: Reduced physical functioning is a risk factor for many adverse outcomes for older adults, including risk of institutionalization and disability. Previous research indicates that leisure-time physical activity (LTPA) in mid-life predicts better physical function at a single timepoint in late-life, but more information is needed on the association between mid-life LTPA and trajectories of physical function in late-life. We hypothesized that higher levels of LTPA in mid-life are associated with attenuated physical function declines in late life. Methods: We studied 5,517 ARIC Study participants (Visit 5; mean age: 75.9 years; range: 67-91 years; 58% women; 21% Black participants) without Parkinson disease or prevalent stroke who completed the Short Physical Performance Battery (SPPB, a composite of gait speed, balance, and chair stands (lowest score 0, highest score 12). SPPB assessments were repeated at Visits 6 and 7 (median follow-up: 4.2 years). Engagement in LTPA was assessed using a modified Baecke Physical Activity Questionnaire in mid-life (Visit 1; mean age: 52 years; mean time between mid- and late-life exams: 23.7 years). Based on minutes/week of moderate-vigorous intensity LTPA participation, participants were classified into poor (0 min/week), intermediate (1-149), or ideal (≥150) LTPA levels, according to American Heart Association (AHA) physical activity recommendations. We also used the average total MET-mins/week and average moderate-vigorous intensity MET-min/week as continuous measures. Random-slope and random-intercept mixed models with an independent covariance structure tested the association between mid-life LTPA and SPPB score change in late-life, adjusted for age, sex, race-center, education, body mass index, smoking, diabetes, and hypertension. Results: SPPB scores declined an average of 2.19 points per 10 years (95% CI: -2.43, -1.96; p&lt;0.001) among older adults who had poor mid-life LTPA. In contrast, participants with intermediate or ideal mid-life LTPA levels declined 0.45 SPPB points less (95% CI: 0.11, 0.78; p&lt;0.001) and 0.65 SPPB points less (95% CI: 0.35, 0.95; p&lt;0.001), respectively, per 10 years compared to those with poor mid-life LTPA. In continuous analyses, each additional standard deviation higher total MET-min/week PA was associated with a 0.24 slower SPPB point decline per 10 years (0.13, 0.36; p&lt;0.001). Continuous results remained consistent when considering only moderate-vigorous intensity MET-min/week. Conclusions: Higher levels of self-reported LTPA at a single time point in mid-life were associated with mitigated physical function declines in SPPB in late-life, over two decades later. Additional research may consider the role of changes in LTPA across mid- and late-life and of other types of physical activity, as well as sedentary behaviors, in further understanding the association.

Low Amount and Intensity of Leisure-time Physical Activity in Asian Indian Adults.

We sought to describe leisure-time, aerobic, and muscle strengthening physical activity (PA) patterns in U.S. Asian Indians, in comparison to other races/ethnicities. We utilized the 2011-2018 National Health Interview Surveys, a set of cross-sectional, nationally representative surveys of the U.S. noninstitutionalized population. Our study population included 257652 adults who answered PA questions. PA was classified per 2008 U.S. guidelines and continuously per estimated metabolic equivalents (METs). Race was classified into White, Black, Asian Indian, Other Asian, and American Indian/Alaskan Native/Multiracial. We used survey design-adjusted, multivariable logistic regression to determine odds of sufficient and highly active physical activity levels, adjusting for predisposing, enabling, need, and health care service factors as guided by the Anderson Model. We also used linear regression to determine racial differences in average MET-minutes/week. Analysis was additionally stratified by comorbidity status. While Asian Indians (N = 3049) demonstrated similar odds of sufficient aerobic PA as Whites (aOR [95% CI]: .97 [.88,1.07]), Asian Indians had 22% lower odds of meeting highly active aerobic PA levels (.78 [.71,0.87]) and 18% lower odds of meeting sufficient muscle strengthening PA levels (.82 [.73,0.91]). This translated to an average 172 (95% CI: 45300) fewer MET-minutes. Furthermore, this decrease in MET-minutes/week was especially apparent in those without hypertension (β[95% CI]: -164 [-314,-15]) without diabetes (-185 [-319,-52]), and low/normal BMI (-422 [-623,-222]). Asian Indians, especially those without comorbidities, are less likely to engage in high-intensity physical activity than Whites.

Prospective Associations of Leisure-Time Physical Activity With Psychological Distress and Well-Being: A 12-Year Cohort Study.

This study aimed to investigate the associations of leisure-time physical activity with psychological distress and well-being, and potential mediators. We used data from the 1970 British Cohort Study (n = 5197; 2688 men), including waves 34y (2004), 42y (2012), and 46y (2016). Participants reported leisure-time physical activity frequency and intensity (exposure) at age 34 years (baseline); cognition (vocabulary test), body mass index, disability, mobility and pain perception (potential mediators) at age 42 years; and psychological distress (Malaise Inventory) and well-being (Warwick-Edinburgh scale) at age 46 years. Baseline confounders included sex, country, education, employment status, alcohol use, tobacco smoking, and psychological distress. Main analyses included logistic regression and mediation models. Higher leisure-time physical activity intensity at baseline was associated with lower psychological distress at 46y (β = -0.038 [95% confidence interval {CI} =-0.069 to -0.007]), but not leisure-time physical activity frequency. Baseline leisure-time physical activity frequency and intensity were associated with higher psychological well-being at 46y (frequency: β = 0.089 [95% CI = 0.002 to 0.176]; intensity: β = 0.262 [95% CI = 0.123 to 0.401]); and total: β = 0.041 [95% CI = 0.013 to 0.069]). Only body mass index at 42y partially mediated the association between leisure-time physical activity frequency (15.7%) and total leisure-time physical activity (6.2%) at 34y, with psychological well-being at 46y. Our findings highlight the role of leisure-time physical activity in psychological distress and well-being, with greater effect sizes associated with higher frequency and intensity of leisure-time physical activity. Future interventions should consider examining potential mediators of the association of leisure-time physical activity with psychological well-being, such as body mass index.

Physical inactivity and headache disorders: Cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Physical inactivity has been linked to headache disorders but estimates based on the current World Health Organization physical activity guidelines are unknown. To test the associations between headache disorders and physical inactivity in the ELSA-Brasil cohort. In a cross-sectional analysis, linear (continuous variables) and logistic regression models (categorical variables) tested the associations of physical activity levels in the leisure time, commuting time, and combined leisure time physical activity + commuting time physical activity domains with headache disorders, adjusted for the effects of sociodemographic data, cardiovascular risk variables, psychiatric disorders, and migraine prophylaxis medication. Of 15,105 participants, 14,847 (54.4% women) provided data on physical activity levels and headache. Higher physical activity levels (continuous values) in the leisure time physical activity domain associated with lower migraine and tension-type headache occurrence and lower headache attack frequency, while in the commuting time physical activity domain it associated with more frequent headache attacks. Compared to people who met World Health Organization physical activity levels in the leisure time physical activity or combining leisure time physical activity + commuting time physical activity domains (i.e. ≥150 min.wk-1 of moderate and/or ≥75 min.wk-1 of vigorous physical activity), physical inactivity associated with higher migraine occurrence, while somewhat active (i.e. not meeting World Health Organization recommendations) associated with higher migraine and tension-type headache occurrence. Physical inactivity in the commuting time physical activity domain associated with higher tension-type headache in men and lower migraine in women. Physical inactivity within vigorous leisure time physical activity intensity, but not moderate leisure time physical activity, associated with higher migraine, mostly in women. Finally, physical inactivity associated with higher headache attack frequency regardless headache subtype. Physical inactivity and unmet World Health Organization physical activity levels associate with primary headaches, with heterogeneous associations regarding headache subtype, sex, physical activity domain/intensity, and headache frequency in the ELSA-Brasil study.

Factors associated with leisure-time physical activity participation among individuals with spinal cord injury who ambulate

Purpose The purpose of this study was to employ the theoretical domains framework (TDF) to identify behaviour change factors related to leisure-time physical activity (LTPA) in spinal cord injury (SCI) ambulators. Methods A cross-sectional design was employed. Among 43 SCI ambulators, the TDF behaviour change factors were assessed, along with the duration, types, and intensities of LTPA performed over the previous week. Results The TDF behaviour change factors identified as barriers to LTPA included: knowledge, beliefs about capabilities, coping planning, and goal conflict. Approximately 71.81 mins/day (SD = 75.41) was spent doing LTPA. Participants reported aerobic and resistance training activities, along with several other types of LTPA (e.g., rock climbing). Coping planning, action planning, goal conflict, and skills explained significant variance in time spent on LTPA (R 2 adjusted = 0.259, p < 0.01), but only action planning uniquely predicted LTPA. Conclusions Greater use of coping and action planning, lower levels of goal conflict and stronger skills were associated with greater participation in LTPA. These factors will be targeted for a future LTPA-enhancing intervention for SCI ambulators, informed by behaviour change theory. SCI ambulators participate in a surprisingly wide range of LTPA. Rehabilitation specialists can use this list to suggest activities for patients with SCI who ambulate. IMPLICATIONS FOR REHABILITATION Barriers to leisure-time physical activity for individuals with spinal cord injury (SCI) who ambulate include lack of knowledge, weak beliefs about capabilities, lack of coping planning, and high goal conflict. Physical activity interventions for individuals with SCI who ambulate should include action and coping planning, goal conflict, and skills. Physical activity interventions should be created systematically using behaviour change theory and involvement of stakeholders throughout the development process. Practitioners can promote skills training in adapted activities like gardening, cycling, and rock-climbing for ambulators with SCI.

Physical Activity-Related Metabolites Are Associated with Mortality: Findings from the Atherosclerosis Risk in Communities (ARIC) Study.

Habitual physical activity can diminish the risk of premature death. Identifying a pattern of metabolites related to physical activity may advance our understanding of disease etiology. We quantified 245 serum metabolites in 3802 participants from the Atherosclerosis Risk in Communities (ARIC) study using chromatography–mass spectrometry. We regressed self-reported moderate-to-vigorous intensity leisure-time physical activity (LTPA) against each metabolite, adjusting for traditional risk factors. A standardized metabolite risk score (MRS) was constructed to examine its association with all-cause mortality using the Cox proportional hazard model. We identified 10 metabolites associated with LTPA (p < 2.04 × 10−4) and established that an increase of one unit of the metabolic equivalent of task-hours per week (MET·hr·wk−1) in LTPA was associated with a 0.012 SD increase in MRS. During a median of 27.5 years of follow-up, we observed 1928 deaths. One SD increase of MRS was associated with a 10% lower risk of death (HR = 0.90, 95% CI: 0.85–0.95). The highest vs. the lowest MRS quintile rank was associated with a 22% reduced risk of death (HR = 0.78, 95% CI: 0.62–0.94). The effects were consistent across race and sex groups. In summary, we identified a set of metabolites associated with LTPA and an MRS associated with a lower risk of death. Our study provides novel insights into the potential mechanisms underlying the health impacts of physical activity.

Intensity of Leisure-Time Physical Activity and Dimensions of Mental Well-Being: A Reciprocal Approach Using Parallel Latent Growth Curve Modeling.

The examination of the longitudinal effect of leisure-time physical activity (LTPA) on mental well-being is important, but previous studies have typically been limited by their use of a cross-sectional approach. This study empirically examined how LTPA intensity was associated with changes in distinct functions of mental well-being (eg,emotional, psychological, social) over time, and vice versa. Parallel latent growth curve modeling in combination with propensity score matching analysis was conducted. Data were derived from a sample of adults from the Midlife in the United States (MIDUS) study. The results showed that the initial level of moderate LTPA at the baseline was associated with growth in psychological and social functioning over time, and vice versa. However, vigorous LTPA at the baseline was related only to growth in emotional functioning over time. The longitudinal association between LTPA and mental well-being had different matching mechanisms for LTPA intensities and their relation to distinct functioning for mental well-being. The findings contribute to an enhanced understanding of LTPA's longitudinal effect on mental well-being.
