Health enhancement through activity travel participation and physical activity intensity

IntroductionPast studies investigate the impact of health parameters on activity and transport options. However, limited research has been done on how activity-travel participation influences health outcomes. Physical activity has the potential to improve health characteristics; however, its intensity (duration and frequency) and optimal mode are yet to be determined. Therefore, the current study aims to use physical activity intensity (PAI) as an intermediate variable to study the correlation among daily activities, transport mode choice, and health parameters to pursue sustainable transportation and improve health parameters. MethodsIn September 2013, a multidimensional three-week household survey was used to collect the data containing 191 households and 732 individuals representing 0.029% of the total population of Bandung, Indonesia. SPSS was used for the data normalization and descriptive analysis, whereas R was used for the multilevel regression and structural equation modeling (SEM). Four models were developed between endogenous, mediator, and exogenous variables. ResultsA significant correlation was found between daily activities, transport mode choice, and health parameters with exceptionally acceptable R2 and p-values. The appraised results indicate that strenuous PAI is 2.1% and 0.3% positively correlates with physical health (PH) and social health (SH), showing that it mediates the correlation among transport-related daily activities and health parameters. High-income households are dependent on motorized transport which is 0.1% and 0.2% negatively associated with PH and SH. Whereas, active transport is 2.0% and 0.2% and public transport is 0.2% and 1.5% positively associated with PH and SH. Replacing short car trips with a sustainable transportation system enhances health parameters and reduces GHG emissions from the transportation sector. ConclusionThe current study concluded that the association was mediated by transport-related PAI which enhances health parameters. Policymakers and practitioners promote transport-related physical activity which may help to enhance health parameters and provide a sustainable transportation system.

Planning strategies and infrastructure development supporting physical activity: analyzing municipal compact city plans in Japan

AbstractAligned with global goals for healthy and sustainable cities, urban compactness significantly promotes residents’ transport-related physical activity and health. In Japan, amid demographic changes, municipalities have begun formulating Location Normalization Plans focused on making cities more compact. This study examines the associations between health and transport-related physical activity considerations in urban plans, including Location Normalization Plans, the demographic characteristics of municipalities, and the development of infrastructure that supports leisure-time physical activity. Analyzing responses from 725 of 1,374 Japanese municipalities, our research reveals that 38% of urban plans integrated health and physical activity in goals/visions, and 28% recognized these as challenges. The development of physical activity infrastructure such as sports facilities (48%), metropolitan parks (21%), and bicycle paths (14%) was more prevalent in larger municipalities. However, the incorporation of health and physical activity in planning goals/visions or challenges was not exclusive to larger municipalities; smaller ones also demonstrated this capability. Logistic regression analyses revealed that municipalities that included health considerations in their plans’ goals/visions and challenges were more likely to develop or renovate physical activity infrastructure. Prioritizing health and physical activity in planning has the potential to support leisure-time and transport-related physical activity, helping to create healthy and sustainable cities.

35 Associations between transport modes and site-specific cancers: A Systematic review and meta-analysis

Abstract Purpose Transport choices may influence cancer risks through their effects on physical activity levels, sedentary time, and environmental pollution. This review synthesizes existing evidence on the associations of specific transport modes with risks of site-specific cancers. Methods Relevant literature was searched up to 17th February 2023 in PubMed, Embase, and Scopus, and results were meta-analyzed for cancer sites where two or more studies were identified. Results 27 eligible studies (11 cohort, 15 case-control, and 1 case-cohort) were identified, which reported the associations with 10 site-specific cancers (breast, endometrial, colorectal, testicular, prostate, ovarian, lung, renal, liver, gallbladder and biliary tract). In meta-analysis, 10 Metabolic Equivalent of Task hour increment in transport-related physical activity per week (∼ 150 minutes of walking or 90 minutes of cycling for commute) was associated with a 7% reduction in risk for endometrial cancer (95% CI: 0.89 – 0.98), 5% reduction for colorectal cancer (95% CI: 0.91 – 0.99) and 2% reduction for breast cancer (95% CI: 0.89 – 0.996). Compared to motorized modes, cycling was associated with a lower risk of overall cancer incidence and mortality. Conclusion Active transport appears to reduce cancer risk, but evidence for cancer sites other than colorectum, breast, and endometrium is currently limited.

Relationship between domain-specific physical activity and cognitive function in older adults - findings from NHANES 2011-2014.

To determine the relationship between domain-specific physical activity (PA) (e.g., occupational PA [OPA], transport-related PA [TPA], and recreational PA [RPA]) and cognitive function in older adults. The data was obtained from the 2011-2014 cycle of the NHANES. We utilized weighted multivariate linear regression models among the included 2,924 people aged 60 years or older for our purposes. RPA and total PA according to WHO guidelines were associated with verbal fluency (RPA β: 1.400, 95% CI: 0.776, 2.024, p = 0.002; total PA β: 1.115, 95% CI: 0.571, 1.659, p = 0.001), processing speed and executive function (RPA β: 2.912, 95% CI. 1.291, 4.534, p = 0.005; total PA β: 2.974, 95% CI: 1.683, 4.265, p < 0.001) were positively correlated, and total PA was correlated with delayed memory performance (β: 0.254, 95% CI: 0.058, 0.449, p = 0.019). No significant association was observed between OPA, TPA, and various aspects of cognitive function among individuals over 60 years. There was no noteworthy correlation discovered between OPA and TPA in relation to cognitive function. However, RPA and total PA exhibited significant associations with verbal fluency, processing speed, and executive function. Additionally, maintaining PA levels ranging from 600 to 1,200 MET-min/week would yield the most favorable outcomes for cognitive function.

Development and psychometric testing of a questionnaire for the Korea Youth risk behavior survey to assess physical activity behaviors

BackgroundPhysical activity is essential for physical, mental, and cognitive health. Providing evidence to develop better public health policies to encourage increased physical activity is crucial. Therefore, we developed an in-depth survey as part of the Korea Youth Risk Behavior Survey to assess the current status and determinants of physical activity among Korean adolescents.MethodsWe developed an initial version of the questionnaire based on a review of validated questionnaires, recent trends and emerging issues related to adolescent physical activity, and the national public health agenda pertaining to health promotion. Content validity was confirmed by a panel of 10 experts. Face validity was confirmed through focus group interviews with 12 first-year middle school students. The test-retest reliability of the questionnaire was evaluated by administering it twice, approximately two weeks apart, to a sample of 360 middle and high school students. Additionally, the frequency or average number of responses was analyzed in a sample of 600 students who participated in the initial test-retest reliability evaluation of the questionnaire developed in this study.ResultsThrough item pool generation and content and face validity test, the final 15 questionnaire items were developed across five themes: levels of physical activity, school sports club activities, transportation-related physical activity, physical activity-promoting environments, and factors mediating physical activity. The test-retest reliability ranged from fair to substantial. Results from the newly developed survey reveal that only a minority of adolescents engage in sufficient physical activity, with only 17.2% and 21.5% participating in vigorous and moderate-intensity activities, respectively, for at least five days per week. Among school-based activities, 44.3% of students do not participate in school sports clubs due to reasons including absence of clubs and disinterest in exercise. The major motivators for physical activity are personal enjoyment and health benefits, whereas preferences for other leisure activities and academic pressures are the predominant barriers.ConclusionsThis study developed valid and reliable in-depth survey items to assess physical activity among Korean youths. It will hopefully enhance our understanding of adolescent physical activity, offering essential preliminary evidence to inform the development of public health strategies aimed at promoting adolescent health.

Investigating young children’s physical activity through time and place

BackgroundPrevious research indicates the start of primary school (4-5-year-old) as an essential period for the development of children’s physical activity (PA) patterns, as from this point, the age-related decline of PA is most often observed. During this period, young children are exposed to a wider variety of environmental- and social contexts and therefore their PA is influenced by more diverse factors. However, in order to understand children’s daily PA patterns and identify relevant opportunities for PA promotion, it is important to further unravel in which (social) contexts throughout the day, PA of young children takes place.MethodsWe included a cross-national sample of 21 primary schools from the Startvaardig study. In total, 248 children provided valid accelerometer and global positioning (GPS) data. Geospatial analyses were conducted to quantify PA in (social) environments based on their school and home. Transport-related PA was evaluated using GPS speed-algorithms. PA was analysed at different environments, time-periods and for week- and weekend days separately.ResultsChildren accumulated an average of 60 min of moderate-to-vigorous PA (MVPA), both during week- and weekend days. Schools contributed to approximately half of daily MVPA during weekdays. During weekends, environments within 100 m from home were important, as well as locations outside the home-school neighbourhood. Pedestrian trips contributed to almost half of the daily MVPA.ConclusionsWe identified several social contexts relevant for children’s daily MVPA. Schools have the potential to significantly contribute to young children’s PA patterns and are therefore encouraged to systematically evaluate and implement parts of the school-system that stimulate PA and potentially also learning processes. Pedestrian trips also have substantial contribution to daily MVPA of young children, which highlights the importance of daily active transport in school- and parental routines.

Uncovering physical activity trade-offs in transportation policy: A spatial agent-based model of Bogotá, Colombia

BackgroundTransportation policies can impact health outcomes while simultaneously promoting social equity and environmental sustainability. We developed an agent-based model (ABM) to simulate the impacts of fare subsidies and congestion taxes on commuter decision-making and travel patterns. We report effects on mode share, travel time and transport-related physical activity (PA), including the variability of effects by socioeconomic strata (SES), and the trade-offs that may need to be considered in the implementation of these policies in a context with high levels of necessity-based physical activity.MethodsThe ABM design was informed by local stakeholder engagement. The demographic and spatial characteristics of the in-silico city, and its residents, were informed by local surveys and empirical studies. We used ridership and travel time data from the 2019 Bogotá Household Travel Survey to calibrate and validate the model by SES. We then explored the impacts of fare subsidy and congestion tax policy scenarios.ResultsOur model reproduced commuting patterns observed in Bogotá, including substantial necessity-based walking for transportation. At the city-level, congestion taxes fractionally reduced car use, including among mid-to-high SES groups but not among low SES commuters. Neither travel times nor physical activity levels were impacted at the city level or by SES. Comparatively, fare subsidies promoted city-level public transportation (PT) ridership, particularly under a ‘free-fare’ scenario, largely through reductions in walking trips. ‘Free fare’ policies also led to a large reduction in very long walking times and an overall reduction in the commuting-based attainment of physical activity guidelines. Differential effects were observed by SES, with free fares promoting PT ridership primarily among low-and-middle SES groups. These shifts to PT reduced median walking times among all SES groups, particularly low-SES groups. Moreover, the proportion of low-to-mid SES commuters meeting weekly physical activity recommendations decreased under the 'freefare' policy, with no change observed among high-SES groups.ConclusionsTransport policies can differentially impact SES-level disparities in necessity-based walking and travel times. Understanding these impacts is critical in shaping transportation policies that balance the dual aims of reducing SES-level disparities in travel time (and time poverty) and the promotion of choice-based physical activity.

Abstract 3413: Physical activity and sedentary behavior of cancer survivors compared to individuals without cancer in NHANES

Abstract INTRODUCTION: Physical activity may improve quality of life and reduce mortality among cancer survivors. As cancer death rates continue to decrease, the population of cancer survivors is expected to grow, therefore making it important to study their health behaviors. Research has been conducted on prevalence of physical activity and sedentary behaviors of survivors of certain cancers, however, little research has been conducted comparing cancer survivors to individuals without cancer. The purpose of this study was to update previously published results from earlier National Health and Nutrition Examination Survey (NHANES) cycles (2007-2010) with more recent data comparing physical activity and sedentary behavior among cancer survivors and individuals without cancer. METHODS: Using the NHANES 2011-2018, we identified 1320 cancer survivors and 19,109 participants without cancer who provided data on recreational, work-related, and transportation-related physical activity and sedentary behavior. The included participants were over 20 years of age, not pregnant at the time of the survey, and were more than three years from their cancer diagnosis, if applicable. Comparisons between cancer survivors and individuals without cancer were conducted for duration of total physical activity (min/day) and sedentary time per day. To account for the complex sampling design, weighted multivariable analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Compared to individuals without cancer, cancer survivors reported less average ± standard error physical activity minutes per day (190.06 ± 5.24 and 147.29 ± 13.14, respectively), and slightly more sedentary hours per day (6.95 ± 0.09 and 7.56 ± 0.36, respectively). However, after adjusting for age, race and ethnicity, sex, educational status, body mass index, and smoking status, there was no association between physical activity duration or sedentary time and cancer survivor status. The OR (95%CI) for more than 60 minutes per day of physical activity was 1.00 (0.83, 1.20) compared to no physical activity, and for more than 8 hours of sedentary time per day was 1.00 (0.82, 1.21) compared to less than 5 hours per day. DISCUSSION: In a previous publication of earlier cycles of NHANES (2007-2010), cancer survivors reported higher physical activity but also higher sedentary time per day compared to individuals without cancer. However, these results were not supported in this updated analysis using more recent NHANES cycles (2011-2018). After adjustment for important covariates, we did not find differences between cancer survivors and individuals without cancer in reported physical activity or sedentary time. Further research in other populations is needed to corroborate these findings and document whether they reflect a growing awareness of the negative impact of sedentary behavior in cancer survivorship.

Abstract P215: Activity Behaviors and Cardiometabolic Health Outcomes in People Living With HIV

Introduction: Physical activity (PA) and sedentary behavior (SB) are independently associated with cardiometabolic health; data on activity behaviors and cardiometabolic health among people living with HIV (PWH) are limited. Hypothesis: Activity behaviors would differ by age and that not meeting PA Guidelines would be associated with an increased risk of cardiometabolic diseases among PWH. Methods: Using NHANES 2007-08 through 2017-18, PWH (n=125; age 44.3 yrs) were characterized as emerging (18-29 yrs), early (30-44 yrs) and middle (45-59 yrs) adulthood. Achieving Guidelines (≥150 min/wk) was derived from self-reported PA across three domains. SB was reported as time spent sitting. Chronic conditions were high cholesterol, obesity, hypertension, and chronic kidney disease. Prevalence estimates of joint high SB (≥8 h/day) and inactivity (&lt;10 min/wk) were calculated, and regression models were used to estimate differences in behaviors by age and investigate the association between achieving Guidelines and chronic conditions. Results: PWH reported 395.8 min/day of SB with 37.5% spending over 8 h/day sitting. There was no significant difference in SB across lifestage. A total of 67.2% achieved Guidelines although 14% were jointly inactive and highly sedentary. Compared with early adult PWH, middle adult PWH spent more time performing transport-related PA (β= 102.7 min/wk, p =0.009) and less time performing leisure-time PA (β= -211 min/wk, p =0.044) ( Figure ). Compared with PWH meeting Guidelines , those that did not meet Guidelines had higher diastolic blood pressure (β= 6.1 mmHg [CI: 2.6, 9.6]) and higher odds of obesity (OR=2.5[CI: 1.0, 6.4]). Conclusions: Domain-specific differences occurred in transportation and leisure time PA among PWH - a high-risk group for cardiovascular disease. Not meeting the Guidelines resulted in greater odds of obesity and higher diastolic blood pressure. Future research should incorporate device-based measures of movement to understand its relation to chronic disease in PWH.

Association of domain-specific physical activity with albuminuria among prediabetes and diabetes: a large cross-sectional study

BackgroundAlbuminuria, the presence of excess of protein in urine, is a well-known risk factor for early kidney damage among diabetic/prediabetic patients. There is a complex interaction between physical activity (PA) and albuminuria. However, the relationship of specific-domain PA and albuminuria remained obscure.MethodsAlbuminuria was defined as urinary albumin/creatinine ratio (ACR) > 30 mg/g. PA was self-reported by participants and classified into transportation-related PA (TPA), occupation-related PA (OPA), and leisure-time PA (LTPA). Weighted logistic regression was conducted to compute the odds ratios (ORs) and 95% confidence intervals (CIs). Restricted cubic spline (RCS) was used to evaluate the dose–response of PA domains with the risk of albuminuria.ResultsA total of 6739 diabetic/prediabetic patients (mean age: 56.52 ± 0.29 years) were enrolled in our study, including 3181 (47.20%) females and 3558 (52.80%) males. Of them, 1578 (23.42%) were identified with albuminuria, and 5161(76.58%) were without albuminuria. Diabetic/prediabetic patients who adhered the PA guidelines for total PA had a 22% decreased risk of albuminuria (OR = 0.78, 95%CI 0.64–0.95), and those met the PA guidelines for LTPA had a 28% decreased of albuminuria (OR = 0.72, 95%CI 0.57–0.92). However, OPA and TPA were both not associated with decreased risk of albuminuria. RCS showed linear relationship between the risk of albuminuria with LTPA.ConclusionsMeeting the PA guideline for LTPA, but not OPA and TPA, was inversely related to the risk of albuminuria among diabetic/prediabetic patients. Additionally, achieving more than 300 min/week of LTPA conferred the positive effects in reducing albuminuria among diabetic/prediabetic patients.

Analysis of physical activity and prescription opioid use among US adults: a cross-sectional study

BackgroundOpioid crisis has become a global concern, but whether physical activity (PA) can effectively reduce prescription opioid use remains unclear. The study aimed to examine the relationship of different domains of PA (e.g., occupation-related PA [OPA], transportation-related PA [TPA], leisure-time PA [LTPA]) with prescription opioid use and duration of prescription opioid use.MethodsThis cross-sectional study was conducted on 27,943 participants aged ≥ 18 years from National Health and Nutrition Examination Survey (NHANES, 2007– March 2020). We examined the relationship of different domains of PA with prescription opioid use and duration of prescription opioid use using multivariable logistic regression. Stratified analysis and a series of sensitivity analysis were used to elevate robustness. All analyses were conducted using appropriate sampling weights.ResultsOf the 27,943 participants, the mean age was 45.10 years, with 14,018 [weighted, 50.0%] females and 11,045 [weighted, 66.0%] non-Hispanic White. After multivariable adjustment, inverse associations between PA and prescription opioid use were observed for sufficient (≥ 150 min/week) total PA (OR,0.68 95%CI [0.56–0.81]), TPA (OR,0.73 95%CI [0.58–0.92]), and LTPA (OR,0.60 95%CI [0.48–0.75]) compared with insufficient PA(< 150 min/week), but not for sufficient OPA (OR,0.93 95%CI [0.79–1.10]). In addition, the associations were dose-responsive, participants had 22–40%, 27–36%, and 26–47% lower odds of using prescription opioids depending on the duration of total PA, TPA, and LTPA, respectively. Nevertheless, the impact of PA on prescription opioid use varied by duration of opioid use. Sufficient total PA was associated with elevated odds of short-term use of prescription opioids (< 90 days). Comparatively, sufficient total PA, TPA, and LTPA had different beneficial effects on reducing long-term use of prescription opioids (≥ 90 days) depending on the strength of opioids.ConclusionsThis study demonstrated sufficient total PA, TPA, and LTPA were inversely associated with prescription opioid use and varied depending on the duration and strength of prescription opioid use. These findings highlight PA can provide policy guidance to address opioid crisis.

Association Between Different Types of Physical Activity and Hepatic Steatosis and Liver Fibrosis: A Cross-Sectional Study Based on NHANES.

Many studies have shown a link between physical activity (PA) and nonalcoholic fatty liver disease (NAFLD). However, more research is needed to investigate the relationship between different types of PA and NAFLD. This study aimed to explore the potential link between different types of PA, hepatic steatosis, and liver fibrosis. A cross-sectional study was conducted using the data set from the National Health and Nutrition Examination Survey (NHANES) from 2017 to 2020. A multiple linear regression model was used to examine the linear relationship between different types of PA, the controlled attenuation parameter (CAP), and liver stiffness measurement (LSM). In addition, smoothing curve fitting and threshold effect analysis were used to depict their nonlinear relationship. This study involved 5933 adults. Multiple linear regression analysis revealed a significantly negative correlation between leisure-time PA and CAP, while the relationship between occupation-related PA, transportation-related PA, and CAP was not significant. Subgroup analysis further revealed that leisure-time PA was significantly negatively correlated with CAP in women and younger age groups (under 60y old), while the relationship was not significant in men and older age groups. In addition, there was a significant negative correlation between leisure-time PA and liver fibrosis in men. Leisure-time PA can prevent hepatic steatosis, and women and young people benefit more. Occupation-related PA is not associated with hepatic steatosis and cannot replace leisure-time PA. In men, increasing leisure-time PA is more effective in preventing liver fibrosis.

Enhanced body shape change coupled with PA is the key to hypertension management for urban residents.

The present study aimed to assess the relationship between bodyshape, physical activity (PA), and systolic blood pressure (SBP) and diastolic blood pressure (DBP). A novel visualization method was used to examine the effects of body shape combined with physical activity on hypertension. Data from 54,303 participants were obtained from the China Health and Nutrition Survey (CHNS) and analyzed using logistic regression models and standardized regression coefficients of linear models. These models were used to explore factors and effects of body shape indices and other parameters on SBP and DBP. The logistic regression model revealed that compared to transport-related PA, the aggregated variables (weight and waist) were associated with a 2.44-fold and 1.65-fold increase in the risk of hypertension, respectively (p<.05). The average aggregated standardized coefficient of the linear model, based on 1000 bootstrap resamples, indicated that the Base Shape group had the strongest explanatory power for hypertension, followed by the Habits group. However, the explanatory power of the PA group was around 10 and 22 times lower than that of the Base Shape group for DBP and SBP, respectively (p<.05). These results demonstrate that increasing physical activity, with emphasizing a healthy body shape, and adopting positive lifestyle habits can effectively contribute to the prevention and control of hypertension.

Associations of meeting 24-h movement guidelines and metabolic syndrome in Korean adults during the COVID-19 pandemic

ObjectivesThis study aimed to investigate the association between adherence to 24-h movement guidelines and metabolic syndrome (MetS) before and during the COVID-19 pandemic. Study designRepeated cross-sectional design. MethodsWe selected 10,882 adults (2019: n = 5710; 2020: n = 5172) aged ≥20 years from the Korea National Health and Nutrition Examination Survey. Domain-specific physical activity and sedentary behavior were assessed using a global physical activity questionnaire. We also measured the typical sleep duration (h/day) on weekdays and weekends. MetS was defined as the presence of more than three risk factors. ResultsDuring the COVID-19 pandemic, transportation-related physical activity decreased, while the prevalence of abdominal obesity (+3.3 %) and low HDL-C levels (+3.1 %) increased significantly. An elevated risk of MetS was observed in the lower aerobic (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.04−1.58; P = 0.019) and muscular exercise (OR, 1.31; 95% CI, 1.04−1.66; P = 0.023) groups and in the high sedentary behavior (OR, 1.23; 95% CI, 1.00−1.51; P = 0.049) during the pandemic. Sensitivity analysis stratified by sex showed similar patterns with more pronounced changes in MetS components in males. The models also showed significant associations between aerobic physical activity, strength exercises, and sedentary behavior with MetS in males and females. ConclusionsAlthough sedentary behavior and sleep time remained unchanged, a significant decrease in transportation-related physical activity was observed during the pandemic. Moreover, our findings revealed that aerobic physical activity, strength exercise, and sedentary time during the pandemic were associated with an increased MetS risk. These results highlight the importance of promoting physical activity, particularly during periods of social restriction, to mitigate the pandemic's negative effects on metabolic health.

Impacts of the first wave of the COVID-19 pandemic on leisure and transportation physical activity among healthcare workers

IntroductionThe COVID-19 pandemic may lead to reduced physical activity (PA) in health care workers (HCWs). ObjectiveTo evaluate leisure and transport-related PA in HCW of a COVID-19-dedicated hospital during the first wave of the COVID-19 pandemic. MethodsThis is a cross-sectional study with a sample of 1,527 HCWs. Socioeconomic aspects, occupational characteristics, and engagement in leisure and transport-related PA were investigated through an online survey administered in August of 2020. ResultsMore than 80 % HCWs performed < 150 min/week of leisure-related PA, and 85 % performed ≤ 30 min/day transport-related PA. Being male was associated with more PA (OR: 1.93; 95 % CI:1.40–2.66) and transport-related PA; working in nursing, physical therapy, and cleaning/housekeeping services was associated with low PA (OR: 0.70; 95 % CI:0.51–0.95). Physicians and administrative staff were less active in transport-related PA. ConclusionsHCWs working in a COVID-19 hospital had low levels of PA in the domains of leisure and transportation.

Association of physical activity with MAFLD/MASLD and LF among adults in NHANES, 2017-2020.

To investigate the correlations between physical activity (PA) and metabolic associated fatty liver disease (MAFLD) or metabolic dysfunction-associated steatotic liver disease (MASLD) within asubstantial population-based survey, and to examine the association between PA and liver fibrosis (LF). Data from the 2017-2020 NHANES cycle were utilized in this study. PA was divided into four types: leisure-time PA (LTPA), transportation-related PA (TPA), occupational PA (OPA) and total time PA (total PA, which is composed of OPA, TPA and LTPA). Weighted logistic regression models were performed to analyze the associations between PA and MAFLD/MASLD and LF. Mediation analysis was used to explore whether LTPA completely mediated the statistically significant relationship between total PA and MAFLD/MASLD or LF. The study encompassed asample size of 5897 participants aged 20years and above, among the total participants, 2568 individuals with MAFLD and 2588 individuals with MASLD. There was no statistically significant correlation observed between OPA/TPA and MAFLD/MASLD and LF; however, active LTPA demonstrated an inverse association with MAFLD/MASLD (OR: 0.548; 95% CI: 0.458, 0.656/OR: 0.543; 95% CI: 0.453, 0.650), as well as anegative correlation with significant/advanced LF (OR: 0.457; 95% CI: 0.334,0.625/OR: 0.427; 95% CI: 0.295,0.619). There was also asignificant inverse association between total PA and MAFLD/MASLD or LF, but this association was carried by the difference in LTPA. Participation in active LTPA is associated with areduced likelihood of MAFLD/MASLD and LF, while neither OPA nor TPA can replace these effects of LTPA.

Joint association of sedentary behavior and physical activity domains with depression in Korean adults: Cross-sectional study combining four biennial surveys (2016-2022).

Although the increased prevalence of sedentary behavior and insufficient physical activity constitutes a global public health concern, there is limited research on their effects on mental health. We investigated the combined association of sedentary behavior (daily sitting or reclining ≥10 h/day) and physical activity domains (evaluated using the Global Physical Activity Questionnaire, including occupational physical activity, leisure-time physical activity, and transportation-related physical activity) with depression (Patient Health Questionnaire-9, cutoff score: 10). This cross-sectional study utilized biennial data of 21,416 adults (age >20 years) from the Korea National Health and Nutrition Examination Survey waves 7-9 (2016-2022). Joint associations were explored by combining sedentary behavior and each physical activity domain into four levels. Sedentary behavior and occupational physical activity increased the risk of depression, leisure-time physical activity decreased the risk only in men, and transportation-related physical activity showed no significant association. Logistic regression each physical activity domain revealed, for men and women, a significantly higher risk of depression in the sedentary behavior (+)/occupational physical activity (+) group than in the sedentary behavior (-)/occupational physical activity (-) group (odds ratio: 3.05 and 2.66, respectively). The sedentary-behavior (+)/leisure-time physical-activity (-) group showed a significantly higher risk of depression than the sedentary behavior (-)/leisure-time physical activity (+) group (odds ratio: 2.50 and 2.14), and sedentary behavior (+)/transportation-related physical activity (-) group also showed a significantly higher risk of depression compared to the sedentary behavior (-)/transportation-related physical activity (+) group (odds ratio: 1.83 and 1.61). With concurrent exposure to sedentary behavior, the occupational physical activity and lack of leisure time and transportation-related physical activity synergistically increased the risk of depression. Encouraging leisure-time physical activity, minimizing rigorous occupational physical activity, and reducing sedentary behavior may reduce depressive symptoms, and research into specific domains of sedentary behavior and the quantity and quality of transportation-related physical activity is needed.

Association between various physical activity domains and overall cancer risk, National Health and Nutrition Examination Survey (NHANES) 2007-2018.

There are very few studies concurrently evaluating the association between multiple physical activity (PA) domains and cancer prevalence. Therefore, this study aims to fill this gap by investigating the link between multiple PA subdomains [occupational PA (OPA), transportation-related PA (TPA), leisure-time PA (LTPA), and total PA] and the likelihood of cancer. The data from National Health and Nutrition Examination Survey (NHANES) 2007-2008, 2009-2010, 2011-2012, 2013-2014, 2015-2016, and 2017-2018 were used in this study. Cancers are the primary outcome variable of interest in this study. PA was self- or proxy-reported using the Global Physical Activity Questionnaire (GPAQ). Multivariable logistic regression models were used, adjusted for covariates. The trend analysis revealed that the prevalence of cancer statistically decreased with the increase in total PA amount. The participants achieving twice the minimum recommended PA guidelines (≥300 minutes) for total PA were 32% [0.68 (0.54, 0.86)] less likely to have cancer. However, significant associations between three PA subdomains (OPA, TPA, and LTPA) and cancers were not found in this study. There is no significant association between any of these three single PA subdomains and cancer prevalence other than total PA. Therefore, this study recommends clinical practice should prioritize promoting comprehensive PA that integrates OPA, TPA, and LTPA to achieve at least 150 minutes per week (i.e. per seven days) initially and progressing towards 300 minutes for optimal cancer prevention.

Levels and types of physical activity in Russia according to the ESSE-RF study: is there a trace of the COVID-19 pandemic?

Aim. To study levels and types of physical activity, as well as its individual socio-demographic and seasonal determinants in the Russian population according to the Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation (ESSE-RF) study.Material and methods. Data from the ESSE-RF2 (2017) and ESSERF3 (2020-2022) was used. The sample included 28731 men and women aged 35-74 from 15 regions. The level of physical activity was assessed using the Global physical activity questionnaire (GPAQ). The following socio-economic and demographic characteristics were taken as covariates: sex, age, place of residence (urban and rural), level of education, marital status, work characteristics, income level, season of the year. Statistical analysis was performed using SPSS version 22 (IBM Corp. USA).Results. The study showed that 27,4% of the sample have insufficient physical activity. Among the low physical activity category, there are more women than men (28,12 vs 26,7%, p&lt;0,001); among men, high physical activity was more often identified (24,1 vs 18,3%, p&lt;0,001). Compared to the urban population, rural residents have higher physical activity rates (23,9 vs 20,3%, p&lt;0,001). The proportion of people with high physical activity is also higher among people with higher income levels (p&lt;0,001). General physical activity in men is higher compared to women, due to work and recreational activity, but transport-related physical activity is significantly higher in women. From 2017 to 20202022, the population level of physical activity decreased.Conclusion. This study provides the most complete description of Russian patterns of physical activity and shows the areas of necessary intervention for the development of measures and programs aimed at increasing physical activity of Russian population.

Neighborhood environment and body mass index in community-dwelling older adults in China: The mediating role of transport-related physical activity

ObjectivesTo examine whether the associations of neighborhood environment and body mass index (BMI) of community-dwelling older adults aged 70 and above were mediated by transport-related physical activity (TRPA). MethodsA bootstrap method was employed to test the mediation model with multisource data from Chongqing, China. ResultsNeighborhood walkability (effect: 0.030, 95% CI [0.001–0.160]) and shopping facility accessibility (effect: 0.002, 95 % CI [0.001 - 0.101]) exhibited positive effects on BMI indirectly through decreasing TRPA duration. Negative indirect effects of sports facility accessibility (effect: –0.004, 95 % CI [–0.112 - –0.003]) and transit accessibility (effect: –0.044, 95 % CI [–0.074 - –0.002]) on BMI were observed through increasing TRPA duration. Park accessibility showed both direct (effect: –0.242, p < 0.05) and indirect (effect: –0.036, 95 % CI [–0.061 - –0.005]) negative correlations with BMI. ConclusionOur findings facilitate neighborhood environment interventions regarding obesity among older adults in developing countries.
