RESUMEN

Job strain is a major concern in the workplace. Work-related stress is an increasing challenge worldwide as it is the leading cause of long-term sickness absences, disability pensions and lower productivity. Rarely studied simultaneously, both leisure-time physical activity (LTPA) and physical fitness (PF), which comprises cardiorespiratory fitness (CRF) and muscular fitness (MF), may have potential in preventing and managing job strain. The current study aimed to investigate whether LTPA, CRF and MF predict perceived job strain. In addition, the study examines reverse associations, that is, whether job strain predicts LTPA, CRF and MF. We used longitudinal population-based data from a Northern Finland birth cohort of 1966 (n = 5363) to analyse LTPA, CRF and MF as well as job strain and its components, job demands and job control, at age 31 years (1997) and 46 years (2012). Leisure-time physical activity was measured with a self-reported questionnaire whereas CRF and MF were measured as part of clinical examination. Linear regression analyses were used to analyse the data. In both men (n = 2548) and women (n = 2815), higher baseline MF predicted lower job strain and job demands 15 years later. In women, higher baseline total LTPA predicted higher job demands, whereas in men, higher CRF predicted lower job strain and higher job control. These associations remained significant, also when adjusted for education and occupational status. In the analyses on reverse associations, higher job control and higher job demands were linked to higher leisure-time moderate-to-vigorous physical activity (MVPA) and total LTPA 15 years later among both men and women, except for the association between job demands and total LTPA among women. These associations remained significant after adjustment for education and occupational status, except for the association of job control with MVPA and total LTPA among men. The association of higher job demands and total LTPA became significant in women. We conclude that LTPA and PF seem beneficial in preventing and managing job strain.

RESUMEN

As Attention-Deficit/Hyperactivity Disorder (ADHD) may have an unknown influence on the self-reports of physical activity of adults with ADHD and there is a need for high quality self-report assessments of this kind, we examined the test-retest reliability and construct validity of the Godin Leisure-Time Exercise Questionnaire-Health Contributions Score (GLTEQ-HCS) in its use with 35 adults with Attention-Deficit/Hyperactivity Disorder (ADHD) (26 females, 9 males; Mage = 28.7, SD = 6.3 years). Participants completed the GLTEQ twice and wore an ActiGraph GT9X-accelerometer for seven-days. An intraclass correlation coefficient (ICC) determined test-retest reliability, and we determined construct validity based on correlations between the GLTEQ-HCS and minutes/day of sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), as well as differences in SB, LPA, and MVPA among the three GLTEQ-HCS subgroups. The GLTEQ-HCS had excellent test-retest reliability [ICC = 0.98, 0.95 to 0.99], and it was positively correlated with MVPA (r = 0.47, p = .006; rs = 0.52, p = .002). There was a significant and large difference in minutes/day of device-measured MVPA between the three GLTEQ-HCS groups [F (2,32) = 7.30, p = .003, η2 = 0.33]. These results provide psychometric support for using the GLTEQ-HCS with adults who have been diagnosed with ADHD.

RESUMEN

The average level of children's motor performance has decreased in the past decades. Therefore, it is important to identify risk- or enabling factors for motor performance. One such factor could be children's participation in leisure activities (LA). LA are non-obligatory and intrinsically motivated activities performed during free time. They include physical activities, such as individual and team sports and other types of activities, such as doing crafts, hanging out with friends, and playing musical instruments. The present study explores how participating in different combinations of LA (i.e. participation patterns) are related to children's motor performance using a person-centered approach. Ninety 6- to 8-year-old typically developing children (57.8% boys) were recruited from six Dutch primary schools. LA participation and motor performance were measured with the Children's Assessment of Participation and Enjoyment questionnaire and the Movement Assessment Battery for Children-2, respectively. Children were grouped in patterns using Cluster Analysis. Comparisons among patterns were performed with one-way multivariate analysis of variance. As hypothesized, children who participated in a greater variety of LA (i.e., higher participation diversity) and who engaged more frequently in each LA (i.e., higher participation intensity) scored better on manual dexterity, balance, and total motor performance compared to those with lower participation diversity and intensity. Based on these findings, coaches, physical educators, and parents should create opportunities for children to participate in a broad range of LA and to engage in these LA frequently.

That is why the objective of this article focuses on assessing the importance of the use of Recreation in an educational and creative free time, from the context of the Basic Sports Formation, in terms of the integral formation of student-athletes. Starting from the analysis of published works related to the subject, the article makes an assessment in the context of the reality of student-athletes in these educational-sports centers. The need to deepen in the study of this population, their particularities and needs to provide them with an adequate use of their free time through varied recreational activities that contribute to their recreational satisfaction, integral formation and improvement of their quality of life is glimpsed.

RESUMEN

Objectives: Adults with spinal cord injury (SCI) are often sedentary, increasing their risk of cardiometabolic diseases. Leisure-time Physical Activity (LTPA) is physical activity completed during recreation time for enjoyment. We aimed to quantify LTPA in people ≥45 years with SCI and to explore its relationship with participants' characteristics. Methods: This is a secondary analysis on a subset of the Australian International SCI Survey in participants ≥45 years, at least 12 months post-injury. We described levels of LTPA and used multivariable regressions to estimate the associations between participant characteristics and LTPA. Results: Of 1,281 participants (mean age: 62.7 years, mean time since injury: 18.7 years; 74% males) 44% reported no participation in LTPA. The average LTPA participation was 197 (SD 352) minutes per week (median: 50). Females (ß = -62.3, 95% CI [-112.9, -11.7]), and participants with non-traumatic injuries (ß = -105.2, 95% CI [-165.9, -44.6]) performed less LTPA. Time since injury was not associated with moderate-to-heavy LTPA (LR: Probability > F = 0.785). Conclusion: LTPA promotion in the SCI population ≥45 years focusing on females and non-traumatic injuries is warranted.

RESUMEN

INTRODUCTION: Physical activity (PA) improves health outcomes for people with type II diabetes mellitus (diabetes), but little is known about PA among Dominicans. The purpose was to evaluate PA participation and perceptions among people with diabetes in the Dominican Republic (DR). METHODS: Participants (N=29) were recruited from an urban diabetes clinic in DR. PA was assessed via accelerometry and Godin Leisure Time Exercise Questionnaire (GLTEQ). RESULTS: Eighteen women and 11 men enrolled (age: 55 ± 13 years; BMI: 28.6 ± 4.5 kg·m-2). Twenty-seven participants reached acceptable wear time. Using a one-minute bout minimum, moderate- to vigorous-intensity PA (MVPA) was 152.2 ± 59.7 min·day-1; no vigorous PA was recorded. GLTEQ scores (103 ± 98) classified 25 participants as active. Around 93% reported that PA was "very important" for their health. There was no association between GLTEQ and MVPA (p>0.2). Participants who reported being "very active" (n=17) did more MVPA than those who were "rarely active" or "somewhat active" (n=10; p=0.02). CONCLUSION: Dominicans with diabetes are highly physically active but do very little vigorous PA. The GLTEQ was not an accurate measure of PA. Future research should develop validated questionnaires and evaluate structured exercise and dietary interventions.

RESUMEN

OBJECTIVE: Whether physical activity could reduce the risk of atrial fibrillation (AF) remains unclear. This study was to investigate the relationship of leisure-time physical activity (LTPA) with AF incidence among Chinese older adults. METHODS: A total of 3253 participants aged ≥60 years from the Guangzhou Heart Study were successfully followed between March 2018 and September 2019. LTPA was assessed using a modified Global Physical Activity Questionnaire. AF was ascertained by 12-lead electrocardiograms, 24-hour single-lead Holter and clinical examination. The Cox proportional hazards model was used to the estimate hazard ratio (HR) and 95% confidence interval (CI) after adjustment for confounders, and the population-attributable fraction (PAF) was estimated. RESULTS: A total of 76 (2.34%) new-onset cases of AF were identified during a median of 31.13 months of follow-up. After adjustment for confounders, subjects who had LTPA at least 10.0 metabolic equivalent (MET)-hours/week had a 55% lower risk of developing AF (HR: 0.45, 95%CI: 0.25-0.81), and at least 20 MET-hours/week reduced the risk by 45% (HR: 0.55, 95%CI: 0.34-0.92). At least 11% (PAF: 11%, 95%CI: 0%-20%) or 14% (PAF: 14%, 95%CI: 0%-26%) of AF cases could be avoided, respectively, if the subjects do LTPA at least 10 MET-hours/week or 20 MET-hours/week. A significant exposure-response trend was also observed between LTPA and AF risk (Plinear-trend = 0.002). For a specific LTPA, doing housework was associated with a 43% reduced risk, while engaging in ball games was associated with an increased risk. CONCLUSION: This prospective cohort study indicated that a higher LTPA volume was associated with a lower AF risk in Chinese older adults.

RESUMEN

Objectives: To investigate the amount of Leisure-Time Physical Activity (LTPA) that people over 45 years with a spinal cord injury (SCI) performed and to determine the frequency, duration, intensity, and modality of LTPA performed. Data Sources: We searched 5 major electronic databases (CINAHL, SCOPUS, EMBASE, MEDLINE, and PubMed) from inception to March 2023. Study Selection: Cross-sectional, longitudinal studies and control arm of controlled trials that assessed LTPA in participants over 45 years old, with a SCI. We included 19 studies in the review and 11 in the meta-analysis. Data Extraction: We followed the PRISMA checklist for Systematic Reviews. Two review authors independently assessed the risk of bias and extracted data on participants' demographics, injury characteristics, and LTPA participation of the included studies. Risk of bias was assessed using the Joanne Briggs Institute critical appraisal tool for cross-sectional studies. Any conflicts were resolved by a third author. Data Synthesis: We found considerable variability in LTPA participation in adults 45 years and older with SCI. An estimated 27%-64% of participants did not take part in any LTPA. A random effects meta-analysis model was completed for studies that reported total or moderate-to-heavy LTPA scores in minutes per week. Overall, participants (n=1675) engaged in 260 [205;329] (mean [95% CI]) mins/week of total LTPA. Those participating in moderate-heavy intensity LTPA (n=364) completed 173 [118; 255] (mean [95% CI]) mins/week. LTPA modalities included walking, wheeling, hand-cycling, basketball, and swimming, among others. Conclusions: While many older adults with SCI seem to be meeting the recommended weekly physical activity volume, many still remain sedentary. There was significant variation in reporting of frequency, intensity, and duration of LTPA and reporting on modality was limited. Because of differences in reporting, it was challenging to compare results across studies. Data constraints prevented subgroup analysis of LTPA disparities between paraplegia and tetraplegia.

RESUMEN

Background: Metabolic-dysfunction-associated steatotic liver disease (MASLD) affects 30% of adults worldwide and is associated with obesity and cardiovascular risk factors. If left untreated, it can progress to severe liver disease. Lifestyle changes such as physical activity and weight loss help to reduce the severity and risk of mortality. This study estimated the impact of MASLD and leisure-time physical activity (LTPA) on mortality and examined how gender mediates this effect in a Southern Italian population. Methods: This work is a population-based prospective cohort study of inhabitants of Castellana Grotte (>30 years old) in Southern Italy, which began in 1985. Participants provided general health information, underwent anthropometric measurements and ultrasonography, and completed a validated questionnaire on their food intake and LTPA. The vital status was tracked through local municipalities Results: In total, 1826 participants (39% with MASLD) were enrolled in this study, drawn from 2970 eligible subjects; the mean age was 51.91 (±14.76) years and 56.2% were men. Subjects with MASLD who practiced low LTPA had a significantly higher risk of death than those who did not have MASLD and practiced high LTPA. In addition, subjects with MASLD who practiced low LTPA were about 19% less likely to survive to the age of 82 years. As regards gender, both men and women with MASLD and low LTPA showed a significant risk of death, but this was higher in women. Conclusions: The presence of MASLD, especially in women, increases the risk of death from all causes. LTPA plays a key role in the disease and reduces mortality in these individuals.

RESUMEN

This cross-sectional study aimed to examine the association of various aspects of physical activity, including intensity, duration, type, and purpose, with the phase angle (PhA), an objective indicator of health, in Korean adults after stratification by sex. Data from the 2022 Korean National Health and Nutrition Examination Survey, a nationwide, representative, population-based survey, were used. In total, 3996 participants were included in the study. Participants self-reported their weekly intensity, frequency, duration of engagement in physical activity. PhA was categorized into two groups on the basis of sex-specific averages. Multiple logistic regression analysis was used to investigate the relationship between physical activity and PhA, and proportional odds logistic regression analysis was performed to determine the association between physical activity and different subclasses of PhA. A positive association was found between sufficiently active aerobic physical activity and PhA compared with inactive physical activity (sufficiently active, male: odds ratio = 1.952, 95% confidence interval = 1.373-2.776; female: odds ratio = 1.333, 95% confidence interval = 1.019-1.745). This association was further strengthened when aerobic physical activity was accompanied by muscle-strengthening activity (sufficiently active with muscle-strengthening activity, male: aOR = 2.318, 95% CI = 1.512-3.554; female: aOR = 1.762, 95% CI = 1.215-2.556) and vigorous-intensity activities (sufficiently active with sufficient vigorous-intensity activity, male: aOR = 2.785, 95% CI = 1.647-4.709; female: aOR = 2.505, 95% CI = 1.441-4.356) and when there was more leisure-time physical activity than occupational physical activity (sufficiently active with more leisure-time physical activity, male: aOR = 2.158, 95% CI = 1.483-3.140; female: aOR = 1.457, 95% CI = 1.078-1.969). Furthermore, the inclusion of muscle-strengthening activity made a significant difference in the values of PhA for males with insufficiently active physical activity (aOR = 2.679, 95% CI = 1.560-4.602). For females with highly active physical activity (aOR = 1.521, 95% CI = 1.068-2.166), the inclusion of muscle-strengthening and vigorous-intensity activities were significantly associated with higher values for PhA. This study can be utilized to provide specific suggestions for better health programs and can change perception that only occupational physical activity is enough. This study also indicated that PhA can be used for personalized health assessments.

RESUMEN

Numerous studies have suggested that the perceived built environment is shaped by the objective built environment and influences human physical activity. However, the empirical examination of this pathway remains scant. Addressing this gap, our study investigates whether the built environment affects leisure-time physical activity through its impact on the perceived built environment, utilizing data collected from 760 residents in Fuzhou, China. Structural Equation Modeling results reveal a modest correlation between objective and perceived built environment elements, with the objective built environment being a stronger predictor of leisure-time physical activity. Notably, perceived recreational facilities significantly mediate the relationship between objective recreational facilities and leisure-time physical activity, accounting for 15% of the variance in physical activity due to objective recreational facilities. This mediation effect is consistent across subpopulations, irrespective of residential self-selection biases. These results highlight the imperative for urban planning and policy to extend beyond mere spatial allocation of amenities to enhancing both the actual and perceived accessibility of these facilities, thus underlining the study's profound implications for public health and urban development strategies.

RESUMEN

BACKGROUND: Previous studies underscore the protective role of physical activity (PA) in bone health, yet the relationship between different PA categories and osteoporosis risk remains less explored. Understanding the relationships helps tailor health recommendations and policies to maximize the effects of preventing osteoporosis. METHODS: The cross-sectional study involves 488,403 UK Biobank participants with heel quantitative ultrasound-estimated bone mineral density (eBMD) data. The longitudinal cohort involves 471,394 UK Biobank participants without initial osteoporosis and with follow-up records. PA exposure categories in our study included sedentary behavior (SB), total PA (TPA), and different category-specific PA including household, leisure, and work PA. The cases of osteoporosis were assessed using the International Classification of Diseases, 10th revision (ICD-10). The linear, logistic, and Cox proportional hazard regression models were used in our study. RESULTS: In the cross-sectional study, 15,818 (3.28 %) participants had osteoporosis. TPA levels have a positive correlation with eBMD and a negative correlation with osteoporosis prevalence. Among different categories of PA, higher levels of leisure PA were correlated with increased eBMD and a lower osteoporosis risk (leisure PA: OR: 0.83, 95 % CI: 0.79 to 0.86;). In the longitudinal study, 16,058 (17.6 % male, 82.4 % female) (3.41 %) individuals developed osteoporosis during an average follow-up of 13 years. We observed consistent protective effects of high levels of PA on osteoporosis incidence risk, particularly within the category of leisure PA (TPA: HR: 0.78, 95 % CI: 0.74 to 0.82; leisure PA:HR: 0.83, 95 % CI: 0.80 to 0.87). Such associations are independent of genetic predisposition, with no evidence of gene-PA interactions, and keep steady among individuals using drugs affecting bone-density. Moreover, among different leisure PA items, strenuous sports, other exercises, and walking for pleasure conferred a substantial protective effect against osteoporosis. Additionally, non-elderly individuals and males exhibited lower osteoporosis risk from PA. CONCLUSION: This study highlights activity categories differently associated with the risk of osteoporosis. Adherence to frequent leisure PA may have a protective effect against osteoporosis. Such associations are independent of genetic susceptibility to osteoporosis and keep steady among individuals using drugs affecting bone-density. This highlights that leisure PA could be suggested as a more effective intervention in the primary prevention of osteoporosis.

RESUMEN

AIM: Adapted paddleboard provides an outdoor leisure-time physical activities (LTPA) opportunity with many health benefits (e.g., physical activity, reduced stress, social engagement). However, nearly 50% of individuals with disabilities do not participate in any LTPA. Quality of LTPA participation influences sustainable adherence, while optimizing participant experiences. An adapted paddleboard program is offered in Quebec City, for adults with physical disabilities, but little is known about how participants perceive their quality of participation. This study aimed to describe individuals with disabilities' perceived quality of participation in the adapted paddleboard program, and to explore their suggestions of strategies to support meaningful engagement in the program. METHODS: An ethnographic mixed-methods design was conducted, consisting of participant observations during the 13-week program and semi-structured interviews based on the Quality Parasport Participation Framework (QPPF). Measure of Experiential Aspects of Participation (MeEAP) questionnaire were collected. A mixed approach of data analysis was used for qualitative data and descriptive statistics were conducted for quantitative data. RESULTS: Nine participants (8F) with various disabilities (42±15 years old) participated in the study. Emergent dimensions of quality of participation included belongingness and autonomy. Facilitators to participation were identified, such as autonomy support through volunteers and provision of adaptive equipment. Barriers to participation included water access and level of individual challenge. Suggested strategies to improve engagement included water access closer to parking and multiple groups for variable skill levels. CONCLUSIONS: Participants expressed high-quality of participation in adapted paddleboarding. The study allows the development of knowledge about conditions that enhance the experience of participating in outdoor LTPA.

Adapted paddleboard is an increasingly popular activity that can be adapted with material and environmental accommodations for people with disabilities to enable and enhance participation in outdoor leisure-time physical activities (LTPA).Several facilitators, such as the safety of the site or the social support created by the group, enhance quality of experience in leisure-time physical activities (LTPA) including adapted paddleboard; therefore, support sustainable adherence in the practice of physical activities, well-being and social participation.Further opportunities to practice LTPA such as adapted paddleboard in a public space to promote social inclusion are necessary.

RESUMEN

Lifestyles maybe associated with the immune and inflammatory state of human body. We aimed to comprehensively explore the relationship between lifestyles and circulating immune-inflammatory markers in the general population. Data from NHANES 1999-2014 was used. Lifestyle factors included leisure-time physical activity (LTPA), diet quality (Healthy Eating Index-2015, HEI-2015), alcohol consumption, cigarettes smoking, sleep hour and sedentary time. Immune makers included C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), platelet-lymphocyte ratio (PLR) and monocyte-lymphocyte ratio (MLR). Generalized linear regression models were used to adjust confounders. Regressions of restricted cubic splines were utilized to evaluate the potentially non-linear relationships between exposures and outcomes. As results, HEI was negatively associated with CRP (P < 0.001), SII (P < 0.001), and NLR (P < 0.001). Cigarettes per day was positively associated with CRP (P < 0.001), SII (P < 0.001), and NLR (P = 0.008). Alcohol consumption was negatively associated with CRP (P < 0.001), but positively associated with PLR (P = 0.012) and MLR (P < 0.001). Physical activity was negatively associated with CRP (P < 0.001), SII (P = 0.005), and NLR (P = 0.002), but positively associated with PLR (P = 0.010). Participants with higher healthy lifestyle score had significantly lower CRP, SII and NLR (all P values < 0.05). Most of the sensitivity analyses found similar results. In conclusion, we found significant associations between lifestyles and immune markers in the general population, which may reflect a systemic inflammatory response to unhealthy lifestyles.

RESUMEN

BACKGROUND: Since physical activity is an important determinant of physical and mental health, lower levels of physical activity among mothers reported in previous research are concerning. The aim of this study was to examine whether physical activity levels differ among mothers depending on the age of the youngest child. METHODS: Cross-sectional data from the German National Cohort study, comprising 3959 mothers aged 22-72 years with offspring aged 0-54 years (grouped into 0-5, 6-11, 12-17, 18-29 and > 30 years) was used. The Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity among mothers in leisure time, transport and (occupational and non-occupational) work settings, quantified as MET-minutes per week. Means (with 95% confidence interval) of mothers' weekly MET-minutes were visualized in graphs, stratified by mothers' and the youngest child's age. Linear regression analyses assessed the association between the child's age and self-reported time and intensity of mothers' physical activity within each activity domain and for the total physical activity. RESULTS: Adjusted results suggested that the MET-minutes in work settings were lower among mothers with younger children. This association was clearest in mothers whose youngest child was under 12 years old, among whom lower self-reported physical activity at work compared to mothers with children at age 30 and older was found. No association was observed between the age of the youngest child and mothers' MET-minutes in leisure nor in transport settings. The self-reported physical activity of mothers whose youngest child was in the same child age group was found to be lower with increased maternal age. As expected, the work related activity dominated the self-reported physical activity. CONCLUSIONS: The results show differences in mothers' self-reported physical activity by the age of the youngest child. The strongest difference was related to physical activity in work settings, indicating the need for supportive actions.

RESUMEN

BACKGROUND: Patterns of physical activity and sedentary behavior among postmenopausal women are not well characterized. OBJECTIVES: To describe the patterns of accelerometer-assessed physical activity and sedentary behavior among postmenopausal women. DESIGN: Cross-sectional study. METHODS: Women 63-97 years (n = 6126) wore an ActiGraph GT3X + accelerometer on their hip for 1 week. Latent class analysis was used to classify women by patterns of percent of wake time in physical activity and sedentary behavior over the week. RESULTS: On average, participants spent two-thirds of their day in sedentary behavior (62.3%), 21.1% in light low, 11.0% in light high, and 5.6% in moderate-to-vigorous physical activity. Five classes emerged for each single-component model for sedentary behavior and light low, light high, and moderate-to-vigorous physical activity. Six classes emerged for the multi-component model that simultaneously considered the four behaviors together. CONCLUSION: Unique profiles were identified in both single- and multi-component models that can provide new insights into habitual patterns of physical activity and sedentary behavior among postmenopausal women. IMPLICATIONS: The multi-component approach can contribute to refining public health guidelines that integrate recommendations for both enhancing age-appropriate physical activity levels and reducing time spent in sedentary behavior.

RESUMEN

OBJECTIVES: Leisure-time physical activity (LTPA) can reduce the risk of incident diabetes, whereas the role of occupational physical activity (OPA) in developing diabetes is still unclear due to conflicting evidence. Moreover, the joint associations of OPA and LTPA with incident diabetes among US workers have not yet been systematically examined. The objective of this study was to assess the independent and joint associations of OPA and LTPA with incident diabetes. METHODS: This prospective cohort study included 1406 workers free from diabetes at baseline (2004-2006) from the national, population-based Mid-life in the United States (MIDUS) study. Associations of OPA and LTPA at baseline with incident diabetes during 9 years of follow-up were examined using Poisson regression models. High OPA was defined based on engagement in physical demands at work, and high LTPA was defined as participation in moderate or vigorous LTPA at least once per week. RESULTS: High OPA was associated with an increased risk of diabetes compared to low OPA (adjusted risk ratios and 95% confidence interval = 1.52 [1.04, 2.22]), while high LTPA was associated with a decreased risk of diabetes compared to low LTPA (0.66 [0.44, 0.97]). Diabetes risk was the highest among workers with high OPA and low LTPA (2.30 [1.30, 4.07]). CONCLUSIONS: In a national, population-based prospective cohort study of US workers, high OPA was associated with an elevated risk of diabetes, while high LTPA was associated with a decreased diabetes risk. The combination of high OPA and low LTPA exhibited the greatest risk of diabetes.

RESUMEN

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world. The increasingly sedentary lifestyle in recent years may have accelerated the development of NAFLD, independent of the level of physical activity. OBJECTIVE: The purpose of this cross-sectional study was to determine the association between leisure-time physical activity (LTPA) and time spent sitting (TSS) and the likelihood of developing NAFLD in a sample of men and women aged 18-64 years, from southern Italy. DESIGN: The study is based on two cohort studies, a randomized clinical trial and an observational cost-benefit study. PARTICIPANTS: A total of 1269 participants (51.5% women) drawn from 3992 eligible subjects were enrolled in this study. EXPOSURES: Leisure-time physical activity (LTPA) and time spent sitting (TSS) were assessed using the Italian long form of the International Physical Activity Questionnaire (IPAQ-LF), designed for administration to adults aged 18 to 65 years. MAIN MEASURES: The association of exposures with the probability of belonging to a certain NAFLD degree of severity. KEY RESULTS: The probability of having mild, moderate, and severe NAFLD tends to decrease with increasing LTPA and decreasing TSS levels. We selected a combination of participants aged 50 years and older stratified by gender. Men had a statistically significant difference in the probability of developing moderate NAFLD if they spent 70 h per week sitting and had low LTPA, while among women there was a statistically significant difference in the probability of developing mild or moderate NAFLD if they had moderate LPTA and spent 35-70 h/week sitting. CONCLUSIONS: The study thus showed that the amount of LTPA and the amount of TSS are associated with development and progression of NAFLD, but this relationship is not a linear one-especially in women aged ≥ 50 years old.

RESUMEN

BACKGROUND: Cancer patients have a higher risk of depression and are associated with severe adverse prognosis. The relationship between leisure-time physical activity (LTPA) and depressive symptoms in cancer patients is currently unclear. Therefore, our study mainly explores the potential association between LTPA and the weekly cumulative time of LTPA with depressive symptoms in cancer patients. METHODS: We included and analyzed 3368 cancer patients (aged >20 years) from the National Health and Nutrition Examination Survey (NHANES) of the United States from 1999 to 2018. The LTPA score was evaluated through a self-report questionnaire, while depressive symptoms were evaluated through the Health Questionnaire-9 (PHQ-9). Multiple logistic regression analysis was used to explore the relationship between LTPA duration and the occurrence of cancer-related depressiive symptoms. Linear correlation was studied using the restricted cubic spline method. RESULTS: According to a fully adjusted multivariate logistic regression model with confounding variables, the odds ratio (OR) between LTPA and depressive symptoms in cancer patients in this study was 0.59 (95 % confidence interval = 0.39, 0.92; P = 0.02). When the LTPA level was ≥300 min/week, the incidence of depressive symptoms was reduced by 59 % (OR = 0.41, 95 % CI = 0.21, 0.83). In addition, the cubic spline method was used to obtain a linear negative correlation between LTPA duration and tumor depressive symptoms. CONCLUSION: LTPA was negatively correlated with cancer-related depressive symptoms, and the cumulative time of LTPA/week was linearly correlated with depressive symptoms. The slope of the benefit curve changed significantly when the cumulative time of LTPA reached 600 min per week, suggesting that appropriately increasing LTPA had significant benefits on mental health of cancer patients.
