Physical Activity and Its Association With Body Mass Index: A Cross-Sectional Analysis in Middle-Aged Adults From 4 Sub-Saharan African Countries.

This study aimed to explore association of self-reported physical activity domains of work, leisure, and transport-related physical activity and body mass index (BMI) in 9388 adult men and women from the Africa-Wits-INDEPTH partnership for Genomic (AWI-Gen) study in Africa. Africa-Wits-INDEPTH partnership for Genomic is a large, population-based cross-sectional cohort with participants from 6 sites from rural and urban areas in 4 sub-Saharan African countries. A sex-stratified meta-analysis of cross-sectional data from men and women aged 29-82years was used to assess the association of physical activity with BMI. Overall, meeting physical activity guidelines of at least 150minutes per week was associated with 0.82kg/m2 lower BMI in men (β = -0.80kg/m2; 95% confidence interval [CI], -1.14 to -0.47) and 0.68kg/m2 lower BMI in women (β = -0.68kg/m2; 95% CI, -1.03 to -0.33). Sex and site-specific differences were observed in the associations between physical activity domains and BMI. Among those who met physical activity guidelines, there was an inverse association between transport-related physical activity and BMI in men from Nanoro (Burkina Faso) (β = -0.79kg/m2; 95% CI, -1.25 to -0.33) as well as work-related physical activity and BMI in Navrongo men (Ghana) (β = -0.76kg/m2; 95% CI, -1.25 to -0.27) and Nanoro women (β = -0.90kg/m2; 95% CI, -1.44 to -0.36). Physical activity may be an effective strategy to curb rising obesity in Africa. More studies are needed to assess the impact of sex and geographic location-specific physical activity interventions on obesity.

Abstract P3-03-15: Physical Activity and Risk of Death in Breast Cancer Survivors: A Prospective Study

Abstract BACKGROUND. Strong evidence exists supporting the protective effect of physical activity on the risk of developing breast cancer; however, its impact on survival after breast cancer diagnosis remains controversial with limited research in long-term survivors. The aim of the current study was to evaluate the association of physical activity and risk of all-cause mortality in long-term breast cancer survivors. METHODS. We conducted a prospective cohort of 315 post-menopausal breast cancer survivors who were at least 2 years post their initial diagnosis (median 6 years of survivorship). They initially were diagnosed with early stage (AJCC TNM Stages 0-II) breast cancer between January 1996-December 2012. Baseline interviews were conducted between August 2013 and March 2015, and participants were followed until date of death or study’s end (April 2022). Subjects were queried on physical activity and fatigue using validated questionnaires, Godin Leisure Physical Activity Scale (GLPAS) and Fatigue Symptom Inventory (FSI). Physical activity was defined in 3 levels (active, moderately active, insufficiently active). Cox proportional hazards regression model was used to estimate the association of physical activity with risk of all-cause mortality, adjusted for age at baseline, breast cancer stage, Charlson comorbidity index (CCI), years since cancer diagnosis, fatigue, race/ethnicity, lifetime history of insomnia and depression, and adjuvant cancer treatments (endocrine, chemotherapy and radiation). RESULTS. Of the 315 women, mean age at interview was 71 years (range: 57-86). The cohort included 30% women of color, mainly African American/Black and Asian/Pacific Islander women. Over a maximum follow-up of 8.7 years (median:7.8, IQR:7.3-8.3) after their baseline interview, 45 subjects (14.3%) died due to all causes. The mortality rates were: 12.9 per 1000 person years (PY) for active; 13.4 per 1000 PY for moderately active; and 32.9 per 1000 PY for insufficiently active. In multivariable analysis, compared to insufficiently active women, those who were active or moderately active had a markedly 60% decreased risk of death (active: HR=0.42, 95% CI: 0.21-0.85; moderately active: HR=0.40, 95% CI:0.17-0.95). CONCLUSION: We found that even moderate physical activity was associated with a significantly decreased risk of all-cause death in long-term breast cancer survivors. Survivorship care plans should consider incorporating physical activity because even moderate activity is vital for extending survival as well as health-related quality of life.

Abstract P648: Flattening the Curve: A Behavioural Economics Approach to Increase Activity in Summer Months

Objective: The purpose of this study was to determine if the behavioural economics principle “Fresh Start Effect” was evident within population-based patterns of cycling-specific active transportation (AT). The primary hypothesis was that cycling traffic along AT trails would not exhibit a fresh start effect, compared to cycling traffic along leisure trails. Design and Methods: We triangulated data from three data sources (n=3 million individual data counts) to test this hypothesis. First, the main outcome measure, cycling traffic was captured during summer months (May to September) from 2014 to 2019 with electromagnetic EcoCounters embedded in 5 paved multi-use trails in Winnipeg, Canada. Trails were categorized as AT (bi-modal peaks in traffic in the morning and afternoon) or leisure based on daily patterns of cycling traffic (single peaks of traffic in the afternoon). To confirm trends in AT-based cycling, we used daily bicycle parking data from 2012 to 2019 provided by one of the cities largest companies. To replicate the leisure-based Fresh Start effect trend we used data for fitness centre visits from the largest University in the city between 2017 and 2019. To estimate the weekly trends in occupational attendance we captured sales data from a local coffee shop from 2013 to 2019. Generalized linear mixed effects models compared counts between Mondays and other weekdays for all 4 datasets. Results: Cycling traffic was ~22% lower on Fridays relative to Mondays for both AT trails (-89 counts; 95% CI: -33 to -145counts for AT trails vs -86 counts). Nearly identical trends were observed for leisure type multi-use trails (-86 counts; 95% CI: -38 to -135 counts for leisure trails). Daily rates of occupational bicycle parking (i.e. cycling to work) were 14% lower on Fridays compared the beginning of the week (-7 counts; 95% CI: -4 to -10 counts). Daily rates of fitness centre attendance (i.e. leisure physical activity) were 18% lower on Fridays relative to the beginning of the week (-519 counts; 95% CI: -408 to -630 counts). In contrast to cycling and fitness centre data, daily coffee sales increased 15% on Fridays relative to the beginning of the week, (+42.8 counts; 95% CI: +34.1 - +51.5) suggesting that declines in cycling and leisure physical activity were not related to fewer people working on Fridays. Conclusions: Population-based AT and leisure-based cycling patterns are sensitive to the Fresh Start Effect. These data provide data to guide targeted public health strategies to increase AT and leisure-based cycling in urban areas.

Abstract P311: Lifestyle Factors Substantially Contributed to Urban-Rural Disparity in All-Cause Mortality Among Chinese Adults 65 or Older

Background: Studies on whether lifestyle factors could explain urban-rural differences in mortality risks among Chinese adults 65 years or older are limited. We aim to assess whether and to what extent individual-level lifestyle factors contribute to urban-rural disparity in mortality among older Chinese adults. Methods: Our study included a total of 37,083 adults 65 years or older residents (8,522 city, 8,022 urban and 20,539 rural) from seven waves of the Chinese Longitudinal Healthy Longevity Survey (1998-2014), with follow-up to the latest wave (2018). Five lifestyle factors were examined: smoking, drinking, physical activity, diet and leisure activities. All-cause mortality was ascertained through death registry and information from next of kin. We conducted multivariable Cox proportional hazard models to examine mortality risks and used two measures to estimate the contributions to urban-rural mortality disparity from lifestyle factors, PERM (percentage excess risk mediated) calculated by the change of hazard ratio of the different models divided by the hazard ratio of the adjusted demographics model and AUC (area under the receiver-operating curve). Results: During a median follow-up of 3.24 years, 23,576 death cases were recorded. Report crude differences (death rates by the 3 groups city, town, rural) before adjusting for any vars. After adjusting for demographics, the hazards for town and rural residents were 8.8% and 17.2% higher than city residents, respectively (Table 1, Model 1). Adjustment for leisure activities made the largest difference in explaining the urban-rural disparities (Model 6). Adjustment for all five lifestyle factors explained 36.6% of city-town and 26.1% of city-rural differences (Model 7). AUCs for all models were > 0.7. Conclusion: Lifestyle factors, especially leisure activities, physical activities and diet, contributed substantially to the urban-rural disparity in all-cause mortality of adults aged 65 years or older in China.

Abstract P438: Physical Activity and Calcification of Coronary Arteries, Aorta, and Cardiac Valves: The Atherosclerosis Risk in Communities (ARIC) Study

Background: Regular physical activity (PA) has been associated with reduced risk of coronary heart disease, but conflicting results have been reported regarding its association with coronary artery calcification (CAC), one of the strongest predictors of cardiovascular disease. Moreover, different domains of PA (e.g., sports vs. work) and extra coronary calcification (ECC) have not been extensively studied in this context. Methods: We investigated 2,025 ARIC participants (age 73-95 years) who had no coronary heart disease and underwent a non-contrast cardiac-gated computed tomography scan at visit 7 (2018-19). PA was based on a modified Baecke questionnaire, which provides total and domain-specific (sport, non-sport leisure, and work) PA scores. We modeled the cumulative PA scores in middle-age at visit 1 (1987-89) and visit 3 (1993-95). We explored continuous CAC and ECC (log-transformed [Agatston score+1]) or any CAC and ECC (Agatston score >0 vs. 0) as dependent variables using linear regression and multivariable logistic models, as appropriate. Results: Higher total and domain-specific PA scores showed no association with lower CAC. Among ECC, descending aorta calcification demonstrated the strongest association with total PA scores (coefficient -0.10 [95% CI -0.21, 0.01], p=0.075) ( Figure ). When specific domains were explored, higher sport and work PA scores were significantly associated with lower descending aorta calcification. When we analyzed any CAC and ECC as the outcome variable, the results were generally consistent. Conclusions: Higher PA in midlife was associated with lower calcification of descending aorta in late life. Our results further support the health benefits of PA and unique pathological process across different vascular beds.

Objectives This study is to explore the formation process of family leisure culture of elementary school teacher ski mania and to find out what it suggests to physical activity-oriented leisure activities.
 Methods To this end, a cultural and technical study was conducted on a family who skied in the 2021-2022 season. Data were collected through in-depth interviews, participatory observation, and related data, and data were analyzed through domain analysis and taxonomic analysis.
 Results The process of forming a family leisure culture in elementary school teachers' ski mania was shown in five stages: motivation, preparation, beginning, development, and settlement. The motivation stage was the will of the parents, the growth of the children, and the influence of COVID-19. The preparation stage was the selection of season tickets considering economic efficiency, selection of season rooms(houses) considering safety, and purchase of equipment reflecting the opinions of children. The beginning stage was indicated by spending the weekends at a ski resort, limited environment and practice time, and an environment more attractive than skiing. The development stage appeared as skiing skills developed along with turns, praise and assistance from people around them, and practice of voluntary skiing activities. The settlement stage appeared to form a challenging spirit through trying new slopes seal, strengthen family cohesion, and design the next season.
 Conclusions This study is meaningful in that it raises family cohesion and will to love family through the process of forming a family leisure culture in elementary school teachers ski mania, and presents a case in which nature experience-type leisure activities can be practiced in an era of pandemic such as COVID-19. Furthermore, these leisure activities will provide teachers with an opportunity to relieve stress from teaching life and recharge their bodies and minds.

Lifestyle risks associated with brain functional connectivity and structure.

Some lifestyle factors are related to health and brain function and structure, but the brain systems involved are incompletely understood. A general linear model was used to test the associations of the combined and separate lifestyle risk measures of alcohol use, smoking, diet, amounts of physical activity, leisure activity, and mobile phone use, with brain functional connectivity with the high resolution Human Connectome Project (HCP) atlas in 19,415 participants aged 45-78 from the UK Biobank, with replication with HCP data. Higher combined lifestyle risk scores were associated with lower functional connectivity across the whole brain, but especially of three brain systems. Low physical, and leisure and social, activity were associated with low connectivities of the somatosensory/motor cortical regions and of hippocampal memory-related regions. Low mobile phone use, perhaps indicative of poor social communication channels, was associated with low functional connectivity of brain regions in and related to the superior temporal sulcus that are involved in social behavior and face processing. Smoking was associated with lower functional connectivity of especially frontal regions involved in attention. Lower cortical thickness in some of these regions, and also lower subcortical volume of the hippocampus, amygdala, and globus pallidus, were also associated with the sum of the poor lifestyle scores. This very large scale analysis emphasizes how the lifestyle of humans relates to their brain structure and function, and provides a foundation for understanding the causalities that relate to the differences found here in the brains of different individuals.

Association between the time of physical laboral activities and leisure over shoulder pain in fruitculture workers: A cross-sectional study.

Fruitculture workers are exposed to shoulder pain disorders due to long working times in overhead activities. This study aims to analyze the association between the time of physical work and leisure activities over the perception of shoulder pain intensity in fruit growing workers. This is a descriptive and correlational cross-sectional study. The sample consisted of 180 fruit-growing workers. Multivariable logistic regression was used, with an estimate of the Odds Ratio (OR) and 95% confidence intervals. The dependent variable: Numeric Pain Rating Scale (NPRS) (0-10 points), was categorized as low and high, with cutoff points of NPRS > 3 and NPRS > 4, and was associated with the independent variables (level of physical activity, personal, labour and psychosocial). Workers which are insufficiently active in leisure time are more likely to report high-intensity shoulder pain, NPRS > 3 (OR: 2.39; p = 0.049) and NPRS > 4 (OR: 2.85; p = 0.036). In addition, working time in overhead activities is a risk factor for high-intensity pain for NPRS > 3 and NPRS > 4 (OR = 1.01; p < 0.001). Underweight and normal-weight workers were less likely to report shoulder pain in NPRS > 3 (OR = 0.35; p = 0.020) and in NPRS > 4 (OR = 0.20; p = 0.001). Fruit-growing workers had a high prevalence of severe shoulder pain. In addition, workers who are insufficiently active at leisure, overweight and obese are more likely to report severe pain. It was observed that overhead tasks increase the chances of reporting high-intensity shoulder pain among workers.

The relationship between physical activity and depressive symptoms is domain-specific, age-dependent, and non-linear: An analysis of the Brazilian national health survey

Although there is consistent evidence of the beneficial effects of leisure physical activity (PA) on mental health, the role of PA in the domestic, transport, and occupational domains is inconclusive. This study aimed to analyze the relationship between domain-specific PA and depressive symptoms and examine whether the association is moderated by age in a representative sample of the Brazilian population. Cross-sectional data of 89,923 (52.4% female) individuals aged ≥15 years were analyzed. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Physical activity (min/week) performed in different domains (domestic, transport, occupation, and leisure) was self-reported. Generalized additive models with penalized splines were used to explore associations. Lower leisure-time PA and higher levels of PA in the domestic, occupational, and transport domains at distinct PA thresholds were associated with higher depressive symptoms. Leisure PA, even at lower levels, was associated with lower depressive symptoms compared to no PA at all. The increase in depressive symptoms as a function of occupational PA was observed only at PA levels higher than 40 h/week. Although non-leisure PA levels were related to higher depressive symptoms among the total sample, higher domestic and transport PA levels were related to lower depressive symptoms among older adults. This study provides insights into the non-linearity and age-group dependence of the relationship between domain-specific PA and depressive symptoms in a middle-income country. The evidence suggests that care should be taken on recommending PA regardless of context or domain.

Physical activity and psychological adjustment among retirees: a systematic review

BackgroundHealth-related behaviors may change after retirement and induce changes in the mental health. This systematic review aimed to investigate the nature of changes in physical activity and leisure activities, as well as the relationship between physical activity, leisure, and psychological adjustment among retirees.MethodsSearch of papers was done in three electronic databases of PubMed, ISI Web of Science, and Scopus without constraints on time, geographical regions, or languages in February 2022. The papers that had examined the relationship between physical activity and adjustment among retirees using observational design (cross-sectional or longitudinal) were included in the present study. To evaluate the methodological quality of cross-sectional studies, Joanna Briggs Institute (JBI) Critical Appraisal Checklist, and for longitudinal studies, Newcastle-Ottawa Scale (NOS) were used.ResultsThe search results identified 1458 records. Twenty-six papers were included in this review based on the inclusion and exclusion criteria. The findings of most of these studies indicated a significant positive correlation between physical activity, leisure, and psychological adjustment in retirees. Retirees were mostly engaged in passive leisure activities such as reading, watching TV and movies, and less engaged in physical activities, sport, or physical exercise. General organized assessment of the total physical activity among retirees was not possible.ConclusionsBased on the study findings, it can be stated that there is a positive correlation between physical activity, leisure, and the retirees’ adjustment. Usage of the same and valid measurement method specific to old age and retirement period can be useful in more precise assessment of physical activity and its association with adjustment among retirees.

Abstract A010: Association of allostatic load and overall cancer risk among women during the menopausal transition. [R

Abstract Chronic stress and biological aging are closely related, and both associated with mitochondrial dysfunction, abnormal DNA methylation, telomere shortening, failed allostasis, accumulated reactive oxygen species (ROS), etc. For example, allostatic load (AL), a biomarker of chronic stress, increases with age as a result of the cumulative effects of allostasis across the lifespan. In US, minority populations have accelerated aging that results from chronic exposure to lifetime stressors and unhealthy behaviors. Elevated chronic stress is thought to increase cancer risk, though the results so far have been inconsistent, and the underlying mechanism remains unclear. In this study, we carried out the first study to evaluate the relationship between allostatic load (AL), a biological indicator of chronic stress, and overall cancer risk in a multi-ethnic women cohort, including 3015 women who participated in the Study of Women’s Health Across the Nation (SWAN). Based on the distribution of AL, the study population was categorized into four groups, from the lowest (1st category) to the highest AL group (4th category). At baseline, Black women and Hispanic women were more likely to be in the higher AL categories than White women (p &amp;lt; 0.001). In addition, women who smoked regularly, drank alcohol regularly, had no leisure physical activity, and had restless sleep were also more likely to be in the higher AL categories than their relative counterparts (p &amp;lt; 0.001). We also observed that women in the lower-income category with no health insurance were more likely to be in the higher AL category (p &amp;lt; 0.001). The study then found that women in the 4th category of AL (the highest AL group) had a 1.64-fold increased risk of overall cancer (Hazard ratio (HR): 1.64, 95% confidence interval (CI): 1.04, 2.59). The risk association was further strengthened after adjusting demographics, health behaviors, and socioeconomic factors with an HR of 2.08, suggesting that at least partially, AL may reflect the biological pathways linking those common cancer risk factors and cancer development. In further analysis of individual biomarkers of AL score, we found that higher levels of triglyceride and CRP were associated with increased risk of cancer, highlighting the role of metabolic dysfunction and inflammation in the etiology of cancer development. In summary, our study indicate that AL may be a useful biomarker predictive of cancer risk. Findings from our study contribute essential knowledge to the role of chronic stress and its biomarker, AL, in the etiology of cancer development. Furthermore, AL has potential to serve as target for novel interventions and biomarker for stress reduction-based cancer prevention.

Physical, Leisure, and Daily Living Activities in Patients Before, During, and After Radiotherapy for Cancer: Which Patients Need Support in Activities?

Avoiding inactivity and staying active during cancer therapy have great health effects. The aims of this study were to describe level of daily, leisure, and physical activities before, during, and after radiotherapy and to investigate whether patients who had not restored activity level after radiotherapy differed from patients who had restored activity level regarding different characteristics. In this descriptive longitudinal study, 196 patients undergoing pelvic-abdominal radiotherapy reported their activity level at baseline, weekly during radiotherapy, and at 1 month after radiotherapy. Patients decreased activity level during radiotherapy (P < .001 for all activities): physical activity (34% of patients decreased level), walking (26%), leisure activities (44%), social activities (15%), housework (34%), shopping (28%), and activities in general (28%). Almost half (47%) had not restored activity level after radiotherapy. Patients with colorectal cancer, older than 65 years, who had less education than university, and high capacity in overall daily activities at baseline were more likely than other patients not to restore activity level after radiotherapy. The patients not restoring their activity level after radiotherapy were more likely than others to experience anxious mood (P = .016), depressed mood (P = .003), and poor quality of life (P = .003) after radiotherapy. Patients' activity level decreased during radiotherapy, and almost half of patients did not restore activity level after radiotherapy. Given that restored activity level after radiotherapy was less common in certain subgroups and that patients who restored activity level experienced better quality of life and less frequent anxious and depressed mood, cancer nursing professionals should consider supporting these subgroups of patients in performing activities.

The role of volume and intensity on the association between physical activity and mental health among adolescents: a cross-sectional study.

To analyze the association between volume and intensity of physical activity and mental health among adolescents. Cross-sectional study with 604 Brazilian adolescents. Data were assessed using a self-report questionnaire. The outcomes were suicidal ideation, suspicion of common mental disorders, and negative self-perception of mental health. The independent variables were leisure physical activity at low and moderate-to-vigorous intensities. Volume was analyzed in two ways: any volume (presence vs absence), and volume classified according to amount in minutes of weekly physical activity: inactive (0), low active (1-419), and high active (≥420). Poisson regression was performed to estimate prevalence ratios. Any volume of moderate-to-vigorous physical activity was significantly associated with a lower prevalence ratio of all outcomes (PR 0.67 to 0.77). Compared to inactive adolescents, those who were classified as low active for moderate-to-vigorous intensity, presented a lower likelihood of having suicidal ideation, suspicion of common mental disorders, and negative self-perception of mental health (PR 0.70 to 0.76). Furthermore, high active adolescents in moderate-to-vigorous physical activity presented lower suicidal ideation and negative self-perception of mental health (PR 0.62 and 0.57). The promotion of moderate-to-vigorous intensity physical activity at any volume can benefit the mental health of adolescents, however, no association was evidenced for low intensity physical activity.

Variations of explosive strength for the students of the faculty of physical education and sports depending on the type of sports activities

Explosive strength has a decisive role in the rapid execution of movements and in achieving sports performance. The purpose of the study is to identify the differences in the level of explosive force for the upper and lower body, depending on the involvement in curricular physical activities, leisure physical activities or physical efforts in various sports disciplines. The participants are students of the Faculty of Physical Education and Sport/bachelor’s degree: 147 men (age = 20.82 years old). The study was based on a transversal research, with the division of students into 3 distinct investigation groups (as an independent variable), according to sports majors: IS (individual sports), TSG (team sports games) and NA (non-athletes). 7 lower body explosive force evaluation tests and 6 upper body explosive force evaluation tests were applied. The use of ANOVA/Analysis of variance and the comparison on pairs of sports specializations indicate statistically significant differences for most of the tests, between the TSG and NA, respectively IS and NA groups, with the superiority of the athletes. No significant differences are reported between the TSG and IS groups, with 2 exceptions: in the 30s-Plyometric Push-Ups the IS group has significantly better values, respectively in the 30s-lateral hop for the TSG group (p ≤ 0.05). The results of our study are in line with the average performance values provided by other research in the field (although they are weaker than those of elite athletes). The superiority of the individual values of volleyball players and sprinters/Track and field for the power of the lower body, respectively of combat sports practitioners and practitioners of sports games—which use the muscle groups of the trunk and arms in training—for the power of the upper body is confirmed, so the specificity of the effort also influences the explosive force values.

Sobrepeso em indígenas Sateré-Mawé residentes em área urbana de Parintins, Amazonas

ABSTRACT Objective To verify overweight prevalence in the Sateré-Mawé indigenous population over 18 years of age, residing in the city of Parintins (AM), Brazil, and to assess its associated variables. Methods Household survey performed in the urban area of Parintins in 2017, visiting new households in each interview, completing the census universe. Self-declared Sateré-Mawé, over 18 years of age, residing in the city for a period longer than one year were considered eligible. Overweight was considered for body mass index values ≥ 25 kg/m2 or ≥ 27 kg/m2, for those over 60 years of age. Household information on social assistance, as well as individual information such as speaking the indigenous language, years living in the city and also in the indigenous territory, income, work, schooling, marital status, leisure and transport physical activity level, and time watching television per week were retrieved. The hierarchical logistic model analysis was carried out, calculating the odds ratio and confidence interval (95%). Results A total of 174 subjects participated in the survey, 42% being overweight. Those who spoke the Sateré-Mawé language, number of years living in the city, working outside home and being married had a positive effect on the outcome, but lost significance in the final model. Only transport insufficient physical activity (OR=2.24, 95% CI=1.01-4.98) and being in the age group from 30 to 59 years (OR=8.79, 95% CI=3.41-22.64) maintained statistical significance. Conclusion Efforts to provide visibility to the health situation of urban indigenous populations in Brazil are necessary. Poor transport infrastructure in the city seems to favor transport physical activity levels as a necessity, in addition to age, which is commonly associated with overweight.

Yoga Practice and Choices of Foods, Physical Activity, and Leisure: A Convenience Sampling Survey from India.

Previous surveys from countries other than India reported positive health behaviors in yoga practitioners. The present study aimed to determine with respect to yoga practitioners in India: (i) percentages of yoga practitioners who consumed specific foods, had additional physical activity and leisure activity, (ii) the association between these choices and their yoga practice, and (iii) the association of yoga with adding or avoiding specific foods and with meal timings in a day. This convenience hybrid-mode sampling survey was conducted on 551 yoga-experienced persons. (1) Yoga practitioner respondents ate fruits and vegetables regularly (62.1%), did not consume animal source products (69.2%), alcohol (98.0%), or tobacco (98.4%), had a regular physical activity other than yoga (77.5%) and leisure activities (92.2%). (2) More than 150 min/week of yoga practice and experience of yoga exceeding 60 months was (a) significantly associated with (i) regular consumption of fruits and vegetables, (ii) lower consumption of sugar-sweetened beverages, animal source foods, tobacco, and alcohol (P < 0.05, Chi-square test) and (b) not associated with physical activity or leisure activities (P > 0.05, Chi-square test). (3) Yoga practitioners excluded sugar-sweetened beverages, animal-source foods and fast foods from their diet, whereas they added fruits, vegetables, and plant-based juices to their diet, with earlier first and last meals for the day. In India, yoga practitioner respondents' choices for foods, physical activity, and leisure conform to accepted positive health behaviors. The exclusion of animal-source foods emphasizes the need for well-planned and fortified diets among vegan yoga practitioners.

The correlation between physical inactivity and students' health based on data mining and related influencing factors.

The sedentary behavior among college students has become one of the most important factors affecting the development of physical and mental health. Chronic lack of physical activity may lead to health problems such as decreased physical fitness, and increased psychological disorders. In the post-epidemic era, it is necessary for college students to have a strong immune system, and a strong body cannot be achieved without regular leisure physical activity. Therefore, it is necessary to explore the relationship between relevant health factors and physical activity. This paper presents an optimized COM-B model. And the experimental results show that the optimized model is well applied in describing the current situation of physical activity participation among college students, analyzing the distribution characteristics of socio-demographic variables related to physical activity, and exploring the correlation between physical activity and the subhealth status of college students.

Spirometry and respiratory disease risk factors in firefighters in Almaty

Objective: to ascertain respiratory symptoms, lung function and selected respiratory disease risk factors in firefighters of the city of Almaty. Materials and methods: N=1379, 91% males, firefighters working in Almaty were recruited at the annual screening, where CAT (COPD Assessment Test) and mMRC (Modified Medical Research Council) questionnaires were offered to quantify the severity of respiratory symptoms. We also assessed respiratory risk factors, including cigarette smoking, exposure to environmental tobacco smoke, fossil fuel use for heating and cooking, and regular physical activity, followed by spirometry. Vital capacity (VC), forced VC (FVC) and forced expiratory volume in one second (FEV1) were measured. Results: Median age was 28 (interquartile range (IQR) 25-35) years, years in service median 5 (IQR 3-13) years. 41% of employees were daily cigarette smokers (significantly more among males, 43 vs. 16%), whereas 93% were exposed to environmental tobacco smoke and only 57% were engaged in regular leisure physical activity. With the overall low score of respiratory symptoms, the prevalence of postbronchodilator FEV1/FVC reduction below lower limit of normality in males was 2%, whereas the diagnosis of chronic bronchitis in the past was found in 2% of participants. Conclusions: healthy worker effect in firefighters of Almaty can explain very low prevalence of bronchoobstructive syndrome among those enrolled in this analysis, even despite high smoking prevalence.

Effects of physical activity type and sedentary time on metabolically healthy obesity and metabolically unhealthy normal weight Korean men

Obesity has become a global health challenge linked to morbidity and mortality associated with cardiovascular diseases. This study aimed to compare metabolic health indicators according to obesity phenotypes and examine prevalence according to physical activity (PA) and sedentary time in metabolically healthy obesity (MHO) and metabolically unhealthy normal weight (MUNW). Data were obtained from 3242 men participating in the 7th and 8th Korean National Health and Nutrition Examination Surveys. Participants were divided into four groups based on body phenotype and metabolic health status using obesity. Metabolic health was defined as metabolic syndrome. Representative statistical analyzes were one-way analysis of variance (ANOVA) and multiple logistic regression analysis. Compared with MUNW, the MHO had higher obesity, but systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose (FG), hemoglobin A1c (HbA1c), triglycerides (TG), low density lipoprotein cholesterol (LDLC), and total cholesterol (TC) were significantly lower. In comparison between MHO and metabolically healthy normal weight (MHNW), the same health group, there were no significant differences in SBP, FG, HbA1c, and LDLC. The odds ratio of MUNW in the normal weight group was 1.8 times higher than that of the high group in the low leisure PA group. The group with high sedentary time increased the MUNW odds ratio by 1.5 times compared to the low group. Meanwhile, in the obesity group, the high leisure PA group showed a 1.4-fold increase in the MHO odds ratio compared to the low group. In addition, the low sedentary group showed a 1.6-fold increase in the MHO odds ratio compared to the high sedentary group. In conclusion, MHO had higher adiposity than MUNW, but the metabolic health index was better. Low PA and high sedentary time increased the risk of MUNW even in normal weight. Conversely, high PA and low sedentary time increased the likelihood of MHO in the obesity group.
