Joint Effect of Physical Activity and Sedentary Behavior with the Female Urinary Incontinence: An Analysis of NHANES 2011–2016

Introduction: Our study aimed to assess the independent and joint effects of leisure-time physical activity and sedentary behavior with urinary incontinence (UI). Methods: Data were obtained from the National Health and Nutrition Examination Survey 2011–2016. The primary endpoint was the risk of different subtypes of UI, including stress UI, urgency UI, and mixed UI. The primary exposures were leisure-time physical activity and sedentary behavior. Sedentary behavior was assessed by screen time. Weighted univariate and multivariate logistic regression models were used to observe the independent and joint relationship of leisure-time physical activity and sedentary behavior with UI risk (including stress UI, urgency UI, and mixed UI). Results: In total, 6,927 female participants were included in this analysis. 3,377 females did not have UI, 1,534 had stress UI, 836 had urgency UI, and 1,180 had mixed UI. Screen time with ≥5 h/day was associated with increased odds of urgency UI (odds ratio [OR] = 1.31, 95% confidence intervals (CI): 1.06–1.61), which indicated the relationship of sedentary behavior and urgency UI. Engaging in leisure-time physical activity with of ≥750 metabolic equivalent (MET)·min/week was found to be significantly associated with reduced likelihood of mixed UI (OR = 0.68, 95% CI: 0.55–0.85). Additionally, the interaction term of leisure-time physical activityConclusion: Participants experiencing a lower level of leisure-time physical activity and a higher level of sedentary behavior together might enhance the urgency and mixed UI risk.

Does pain tolerance mediate the effect of physical activity on chronic pain in the general population? The Tromsø Study.

Knowledge is needed regarding mechanisms acting between physical activity (PA) and chronic pain. We investigated whether cold pain tolerance mediates an effect of leisure-time physical activity on the risk of chronic pain 7 to 8 years later using consecutive surveys of the population-based Tromsø Study. We included participants with information on baseline leisure-time PA (LTPA) and the level of cold pressor-assessed cold pain tolerance, who reported chronic pain status at follow-up as any of the following: chronic pain for ≥3 months, widespread chronic pain, moderate-to-severe chronic pain, or widespread moderate-to-severe chronic pain. We included 6834 participants (52% women; mean age, 55 years) in counterfactual mediation analyses. Prevalence decreased with severity, for example, 60% for chronic pain vs 5% for widespread moderate-to-severe chronic pain. People with one level higher LTPA rating (light to moderate or moderate to vigorous) at baseline had lower relative risk (RR) of 4 chronic pain states 7 to 8 years later. Total RR effect of a 1-level LTPA increase was 0.95 (0.91-1.00), that is, -5% decreased risk. Total effect RR for widespread chronic pain was 0.84 (0.73-0.97). Indirect effect for moderate-to-severe chronic pain was statistically significant at RR 0.993 (0.988-0.999); total effect RR was 0.91 (0.83-0.98). Statistically significantly mediated RR for widespread moderate-to-severe chronic pain was 0.988 (0.977-0.999); total effect RR was 0.77 (0.64-0.94). This shows small mediation of the effect of LTPA through pain tolerance on 2 moderate-to-severe chronic pain types. This suggests pain tolerance to be one possible mechanism through which PA modifies the risk of moderate-to-severe chronic pain types with and without widespread pain.

Moderating effect of leisure-time physical activity on the relationship between bullying victimisation and self-esteem in young Finnish men

Background and aimsThe links between bullying victimisation and low self-esteem are well established. However, the relationship between physical activity (PA), bullying victimisation and self-esteem is still rather unexplored. The present study aims to investigate the moderating effect of PA on the relationship between bullying victimisation and self-esteem among young men. MethodsThe sample used for this study is based on registers of the Finnish Defence Forces and consists of questionnaire-based data collected from young healthy men (n = 146 767, aged 18–29 years, mean age 19 years) who started their conscript service during 2015–2021. Self-esteem was measured with the Rosenberg Self-esteem Scale and bullying victimisation and leisure-time PA (LTPA) with single questions. Unadjusted and adjusted linear regression models and the aligned rank transform Anova model were calculated. ResultsThe findings showed that there is a dose-response association of self-esteem with bullying victimisation and LTPA. Furthermore, a significant moderating effect of LTPA was found in the relationship between bullying victimisation and self-esteem. Vigorous LTPA at least once a week seems to lessen the negative effects of bullying victimisation on self-esteem. ConclusionsLTPA may have the potential to buffer against negative mental health outcomes resulting from past experiences of bullying victimisation on a young person's self-esteem. More opportunities for LTPA to support self-esteem among young people should be provided, especially for vulnerable groups and those with limited resources and possibilities to engage with PA.

Association of residential greenness with obstructive sleep apnea among Chinese old adults and the mediation role of PM2.5 and leisure-time physical activity

Few studies have investigated the association of residential greenness with obstructive sleep apnea (OSA). This study was to comprehensively examine the association of residential greenness exposure with OSA and explore the mediating effect of leisure-time physical activity (LTPA) and PM2.5 on the association among Chinese old adults. A prospective cohort study that enrolled 2027 adults aged ≥65 was conducted between 1st July 2015 and 30th September 2019 in Southern China. OSA was ascertained by Berlin Questionnaire. Greenness exposure was measured by contemporaneous and cumulative average normalized difference vegetation index (NDVI) in the 1000 m radius around each participant's residential address. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated by Cox proportional hazards model to assess the impact of greenness exposure on the incidence of OSA after adjusting for confounders. LTPA and PM2.5 were examined as potential mediators in the aforementioned models. A total of 293, nearly 14.5 %, participants developed OSA within 59,251 person-months of follow-up. When comparing the highest with lowest tertiles, both contemporaneous NDVI (>0.351 vs. ≤0.325: HR = 0.20, 95 % CI = 0.13–0.31) and cumulative NDVI (> 0.346 vs. ≤ 0.317: HR = 0.32, 95 % CI = 0.21–0.47) were associated with a reduced risk of OSA after adjusting for confounders. LTPA and PM2.5 significantly mediated the association between greenness and OSA. In conclusion, this study indicated that exposure to higher residential greenness could decrease OSA risk, and this benefit may be achieved by promoting physical activity and decreasing PM2.5 concentration. The findings suggest to formulate targeted interventional strategies by expanding residential greenness to prevent OSA and reduce disease burden.

Dose–response relationship between leisure-time physical activity and biomarkers of inflammation and oxidative stress in overweight/obese populations

ObjectivesThis study aimed to analyze the dose–response relationship between leisure-time physical activity and biomarkers of inflammation and oxidative stress in overweight/obese populations and provide exercise recommendations to regulate inflammation and oxidative stress and reduce the risk of developing obesity-related diseases. DesignSecond analysis of a cross-sectional study. MethodsA total number of 4978 overweight/obese adults were included from the 2015–2018 National Health and Nutrition Examination Survey. Multivariable regressions were conducted to investigate the dose–response relationship between leisure-time physical activity and biomarkers of inflammation and oxidative stress. Subgroup analyses based on the doses and intensities of physical activity and in different participants were performed to provide exercise recommendations. ResultsThe results demonstrated that leisure-time physical activity was negatively associated with inflammatory biomarkers in both overweight and obese populations, and positively associated with antioxidant markers in obese populations. Overweight/obese populations performing leisure-time physical activity at 660–760 min/week (dose calculated as moderate leisure-time physical activity, equals 330–380 min/week vigorous leisure-time physical activity) demonstrated the lowest levels of inflammatory markers. Vigorous leisure-time physical activity was superior to moderate one for overweight/obese populations, especially for inflammation regulation. In addition, the regulatory effect of leisure-time physical activity on inflammation was more significant in overweight/obese populations with hypertension or stroke. ConclusionsThe results suggest that overweight/obese populations can take vigorous-intensity leisure-time physical activity at 330–380 min/week (for example, 60 min/day, 6 days/week, metabolic equivalent = 8) to get the maximum health benefits in terms of inflammation and oxidative stress regulation.

Combined Effect of Leisure-Time Physical Activity and Sedentary Behavior on Abdominal Obesity in ELSA-Brasil Participants.

Abdominal obesity is a pattern of obesity that has been considered a public health problem. Physical activity is considered an important factor for the prevention of abdominal obesity. Increased time in sedentary behavior has been associated with negative health outcomes, including abdominal obesity. The aim of this study was to investigate which combination of leisure-time physical activity and sedentary behavior contributes most to the prevention of abdominal obesity in adults participating in ELSA-Brasil (Longitudinal Study of Adult Health). The study was cross-sectional and participants from the first follow-up of the ELSA-Brasil cohort (2012-2014) were analyzed. The independent variables were physical activity, assessed by IPAQ, and sedentary behavior, assessed by a standard questionnaire applied in ELSA-Brasil; the dependent variable was abdominal obesity, determined by waist circumference. The covariates analyzed were the following: age, education, binge drinking, smoking and menopause. The associations between the dependent variable and the independent variables were analyzed using logistic regression. The odds ratio with 95 CI% was estimated. For men, the combinations were more significant when they were more physically active and spent less time on the sedentary behaviors analyzed, on both a weekday and a weekend day. For menopausal women, both younger and older, all associations of the combinations between sufficient leisure-time physical activity and little time spent in sedentary behaviors contributed to the prevention of abdominal obesity. In non-menopausal women, positive associations were observed in almost all combinations between leisure-time physical activity and sedentary behaviors, with some results that were not statistically significant among younger women. Our results showed that being sufficiently active and reducing the time spent in sedentary behavior was the combination that contributed the most to the prevention of abdominal obesity, both in men and women.

Effect of leisure-time physical activity on blood pressure in people with hypertension: a systematic review and meta-analysis

High blood pressure is a major risk factor for premature death. Leisure-time physical activities have been recommended to control hypertension. Studies examining how leisure-time physical activity affects blood pressure have found mixed results. We aimed to conduct a systematic review examining the effect of leisure-time physical activity (LTPA) on lowering blood pressure among adults living with hypertension. We searched studies in Embase, Medline/PubMed, Web of Science, Physical Education Index, Scopus and CENTRAL (the Cochrane Library). The primary outcome variables were systolic blood pressure (SBP) and diastolic blood pressure (DBP). This systematic review is registered on PROSPERO (CRD42021260751). We included 17 studies out of 12,046 screened articles in this review. Moderate-intensity LTPA (all types) reduced SBP compared to the non-intervention control group (MD −5.35 mm Hg, 95% CI −8.06 to −2.65, nine trials, n = 531, low certainty of the evidence). Mean DBP was reduced by −4.76 mm Hg (95% CI −8.35 to −1.17, nine trials, n = 531, low certainty of the evidence) in all types of LTPA (moderate intensity) group compared to the non-intervention control group. Leisure-time walking reduced mean SBP by −8.36 mmHg, 95% CI −13.39 to −3.32, three trials, n = 128, low certainty of the evidence). Walking during leisure time reduced −5.03 mmHg mean DBP, 95% CI −8.23 to −1.84, three trials, n = 128, low certainty of the evidence). Performing physical activity during free time probably reduces SBP and DBP (low certainty of the evidence) among adults with hypertension.

Thirteen-Year Associations of Occupational and Leisure-Time Physical Activity with Cardiorespiratory Fitness in CARDIA.

Differential effects on fitness are hypothesized to contribute to the opposing health effects of leisure-time physical activity (LTPA) and occupational physical activity (OPA). As such, this study examined cross-sectional and longitudinal associations of fitness with LTPA and OPA. This study examined fitness associations with LTPA and OPA across 13 yr in the Coronary Artery Risk Development in Young Adults study (years 7 (baseline), 10, 15, and 20 (follow-up) examinations). Fitness was measured at baseline and follow-up via symptom-limited maximal graded exercise test (GXT) duration (in seconds), whereas LTPA and OPA were self-reported during each examination. Baseline and follow-up cross-sectional associations of LTPA (low, medium, high) and OPA (0, 1-6, and ≥6 months with OPA) with fitness were examined using linear regression. Longitudinal linear regression examined associations between 13-yr LTPA (low, medium, or high) and OPA (no, decreasing, or increasing) trajectories with fitness at follow-up, adjusted for baseline values. All models adjusted for center, sex, race, age, education, smoking history, alcohol intake, resting blood pressure, diabetes status, and body mass index. Stratified analyses examined associations by sex (female/male), race (Black/White), and LTPA groups. Compared with low, medium, and high LTPA were positively associated with fitness in all analyses ( P < 0.001). Reporting 1-6 or ≥6 months with OPA was negatively associated with fitness in cross-sectional follow-up models ( β = -15.6 and -15.4, respectively; P ≤ 0.01). Longitudinally, those with increasing OPA had lower follow-up fitness compared with no OPA ( β = -16.41, P < 0.01). Negative associations of OPA with fitness were not meaningfully different across sex and race groups. Significant LTPA-OPA interactions were observed ( P < 001). Physical activity research and public health promotion should consider domain-specific associations on cardiovascular health.

The role of leisure-time physical activity in youth for lifelong activity—a latent profile analysis with retrospective life course data

Considering the positive health effects of leisure-time physical activity (LTPA), youth is an important life stage to promote lifelong LTPA. However, the stability of LTPA over the life course is low, and specific predictors of LTPA in youth for lifelong activity have some shortcomings, e.g. neglecting the interacting factors of LTPA within individuals. Therefore, from a person-oriented approach, patterns of LTPA behaviour in youth considering time- and context-related aspects and their relationships with lifelong LTPA were investigated. Life course data from n = 1519 Swiss inhabitants aged between 25 and 76 years were recorded retrospectively using a validated questionnaire (CATI method). Latent profile analyses were used to find the optimal profile solution and for the association with lifelong LTPA auxiliary conditional effect models (controlled for age) were applied. Six distinct patterns emerged. Overall, mostly inactive youth are also the least active in adulthood, whereas several other patterns are associated with a mainly continuous LTPA throughout adulthood. More precisely, multiple constellations in youth occurred to be physically active in at least 80% of the years in adulthood: (1) early starters regarding LTPA in a rather self-organised setting but not with many different LTPAs; (2) late entrants with a variety of different activities and organisational settings; or (3) a high expression in every variable investigated. Consequently, there is not just one type of LTPA behaviour in youth linked to lifelong activity, which indicates that certain aspects of LTPA in youth can be compensated by each other. Implications for LTPA promotion can be derived.

The relationship between leisure-time physical activity and job satisfaction: A dynamic panel data approach.

Previous research has documented a positive effect of leisure-time physical activity (LTPA) on life satisfaction. The relationship between physical activity and the specific domain of job satisfaction is, however, relatively unknown. This study aims to investigate the effects of different frequency levels of LTPA on self-reported job satisfaction and specifically focuses on the two mechanisms of health and recovery from work stress. Using data from the German Socio-Economic Panel (2001-2019), fixed effects and dynamic panel data regression models are estimated to address the problems of unobserved heterogeneity and reverse causality. A mediation and sub-sample analysis shed light on the role of health and work stress. The results reveal that weekly LTPA has a positive effect on job satisfaction and that health represents a channel yielding those benefits. The effect appears to be moderated by work stress. Further, the analysis reveals the importance of considering unobserved heterogeneity and reverse causality when studying this relationship. The findings indicate a positive relationship between regular LTPA and job satisfaction and add plausible causal evidence to the limited literature in this context. The findings yield implications for employers and employees.

Effects of Leisure-Time Physical Activity on Cognitive Reserve Biomarkers and Leisure Motivation in the Pre-Diabetes Elderly.

The purpose of this study was to investigate the change in cognitive reserve biomarkers of the pre-diabetic individual according to the types of leisure-time physical activity (aerobic or resistance physical activity). The research subjects (n = 184) who participated in the survey were pre-diabetic and diabetic patients who were visiting university hospitals and welfare centers. The intervention subjects (n = 36) who were elderly females with pre-diabetes volunteered to participate in the study by performing regular physical exercise (aerobic or resistance exercise). The study participants were 65 years of age or older with pre-diabetes defined by a glycated hemoglobin (HbA1c) level of (5.7–6.4)%. All research subjects performed motivation and stress questionnaire survey. All intervention subjects participated in leisure-time physical activity (LTPA) for 12 weeks. Body composition, HbA1c, and cognitive reserve biomarkers were measured at baseline, and at 6 and 12 weeks. LTPA motivation confirmed that the LTPA participants had a high level of motivation. Stress confirmed that the stress level of LTPA participants was low. Two-way within-factor ANOVA revealed significant group × time interaction for weight (p < 0.05), BMI (p < 0.01), % fat (p < 0.001), SBP (p < 0.05), HbA1c (p < 0.001), BDNF (p < 0.001), and Beta-Amyloid 1–42 (p < 0.001). In both physical activity groups, HbA1c (p < 0.001), NGF (p < 0.05), BDNF (p < 0.05), and Cathepsin B (p < 0.05) improved significantly at 12 weeks, compared to baseline and 6 weeks. In the resistance physical activity group, Beta-Amyloid 1–42 (p < 0.01) and Homocysteine (p < 0.05) significantly decreased at 12 weeks, compared to baseline and at 6 weeks. The LTPA showed high levels of integrated and identified regulation among leisure motive types, and the level of stress was found to be low. The LTPA is effective in reducing the HbA1c levels of the pre-diabetes elderly. In addition, the pre-diabetes elderly were found to have increased NGF, BDNF, and cathepsin B, and decreased Beta-Amyloid 1–42 and homocysteine. Regular leisure-time physical activity has a positive effect on cognitive reserve biomarkers through improving glycemic control by reducing weight and % fat in the pre-diabetes elderly.

Protective Effect of Leisure-Time Physical Activity and Resistance Training on Nonalcoholic Fatty Liver Disease: A Nationwide Cross-Sectional Study.

Background: Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease. The present study aimed to investigate the association of NAFLD with leisure-time physical activity (PA) levels and resistance training (RT). Methods: We used data from large nationwide cohorts in Korea. NAFLD was defined based on the Framingham steatosis index. Participants were categorized into four groups based on RT frequency and adherence to PA guidelines (≥150 min/week of moderate-intensity PA): Low-PA, Low-PA+RT, High-PA, and High-PA+RT. Multiple logistic regression models were used to assess the risk of NAFLD according to leisure-time PA levels and regularity of RT. Results: When compared with Low-PA, High-PA decreased the risk of NAFLD by 17%, and High-PA+RT further decreased the risk by 30%. However, the additional reduction in risk associated with the addition of RT was observed in men (19%), but not in women. In the High-PA group, men had a significantly higher training frequency and period for RT than women. Conclusions: Following the PA guideline may confer protective effects against NAFLD, while adding RT to High-PA can further decrease the risk of NAFLD. Sex-based differences in NAFLD risk in the High-PA+RT group may be due to the differences in the frequency and period of RT.

Vigorous regular leisure-time physical activity is associated with a clinically important improvement in back pain \u2013 a secondary analysis of randomized controlled trials

BackgroundNeck and back pain are musculoskeletal conditions with serious individual and societal consequences. Current evidence about the prognostic value for neck and back pain is limited and conflicting. This prospective cohort study aimed to assess the association between leisure-time physical activity (LPA) and improvement of neck and/or back pain in a working population receiving manual therapy or general care in one of two randomized controlled trials (RCTs).MethodsAnalyses of data from two RCTs evaluating the effect of manual therapies for neck and/or back pain was conducted. Participants (n = 1 464) answered questionnaires about frequency and effort level of LPA at baseline. LPA on moderate or vigorous levels was compared to no or low/irregular moderate and vigorous levels. Pain intensity was assessed with numerical scales at baseline and 3-, 6-, and 12-month follow-up. The outcome was minimal clinically important improvement in pain intensity, defined as ≥2 points improvement in mean pain intensity at follow-up. Crude- and adjusted risk ratios (RR) with 95% confidence intervals (CI) were calculated with Poisson regression analysis and stratified by pain location.ResultsParticipants with neck and/or back pain performing vigorous LPA showed a minimal clinically important improvement after 12 months compared to the control group; RR 1.35 (95% CI; 1.06-1.73). No effect was observed at 3 or 6 months. Moderate LPA did not improve pain intensity in any follow-up. Stratified analyses revealed that the effect of vigorous LPA at 12 months in back pain was RR 1.83 (95% CI; 1.26-2.66) and neck pain RR 1.06 (95% CI; 0.75-1.49).ConclusionsPersons with neck and/or back pain receiving manual therapy or general evidence-based care have greater chance of improvement after 12 months if they prior to treatment frequently practice vigorous LPA. When analyzed separately, the effect was only present for back pain.Trial registrationRegistration in Current Controlled Trials (ISRCTN), Stockholm Manual Intervention Trial (MINT), ISRCTN92249294 BJORN-trial, ISRCTN56954776

Leisure-Time Physical Activity and Cardiovascular Disease Risk Among Hypertensive Patients: A Longitudinal Cohort Study.

Objective: Few studies estimated the effect of leisure-time physical activity (LTPA) on cardiovascular disease (CVD) risk among hypertensive patients in a longitudinal cohort. This study aims to evaluate the association between LTPA and CVD in a longitudinal management cohort of hypertensive patients.Methods: A total of 58,167 hypertensive patients without baseline CVD from a longitudinal cohort were included in this study. LTPA and other covariates were measured at the follow-up four times annually. The primary outcome was CVD events. The association between LTPA and CVD was assessed by the marginal structure model (MSM) and Cox model with adjustment for age, gender, body mass index (BMI), smoking, drinking, diabetes, hyperlipidemia, and antihypertensive medication. The restricted cubic spline and segmented regression were used to assess the dose–response relationship between LTPA and CVD.Results: We recorded 16,332 CVD events; crude incidence of CVD were 89.68, 80.39, 62.64, and 44.04 per 1,000 person-years for baseline 0, 1–150, 151–300, and >300 min/week LTPA, respectively. Compared with inactive LTPA, the adjusted hazard ratios (HRs) estimated by Cox model and MSM-Cox model for CVD associated with 1–150,151–300, and 300 min/week LTPA were 0.85 (95% CI, 0.83–0.88), 0.67 (95% CI, 0.64–0.71), 0.47 (95% CI, 0.44–0.51), and 0.83 (95% CI, 0.76–0.91), 0.58 (95% CI, 0.52–0.63), and 0.39 (95% CI, 0.35–0.44), respectively. Per 60 min/week increase in LTPA was associated with a 13% reduction in CVD risk. LTPA breakpoint was 417 min/week for CVD. Before and after the break-point, the slopes of the piecewise-linear relationship between LTPA and CVD risk were −0.0017 and −0.0003, respectively.Conclusion: LTPA was more strongly associated with the CVD risk than that estimated by conventional analyses based on baseline LTPA; 417 min/week is a breakpoint, after which the incremental health benefits on CVD prevention obtained from the increase in LTPA are much less than before.

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.

Structural Relationship among Physical Self-Efficacy, Psychological Well-Being, and Organizational Citizenship Behavior among Hotel Employees: Moderating Effects of Leisure-Time Physical Activity.

Critics argue that service firms should pay more attention to human resource management’s psychological and voluntary aspects to contribute to overall organizational development. The purpose of this study was to investigate the effects of physical self-efficacy on the psychological well-being and organizational citizenship behavior among hotel employees and the moderating effects of leisure-time physical activity on the relationships between the previously mentioned variables. To achieve the research purpose, 346 hotel employees working at the room, food, beverage, and kitchen departments of 10 hotels located in Seoul, South Korea, participated in the study. The researchers visited their department meetings and provided a brief description of the present study and informed consent forms to participate in the study. After obtaining written informed consent forms, the researchers distributed the surveys and asked participants to complete them. Several statistical analyses, including descriptive statistics, confirmatory factor analysis (CFA) for examining the hypothesized model’s psychometric properties, and structural equation modeling (SEM) for testing the hypotheses were conducted using SPSS Ver. 23.0 and AMOS 23.0. Results revealed that perceived physical ability and self-presentation confidence, and psychological well-being positively affected organizational citizenship behavior. Perceived physical ability also had a positive effect on psychological well-being. Lastly, leisure-time physical activity had a partial moderating role in the relationships between the variables mentioned above. This study suggests that promoting employees’ participation in leisure-time physical activity is needed to improve service workers’ organizational citizenship behavior via physical self-efficacy and psychological well-being enhancement.
