Assessment of Pedagogical Contributions toward Enhancing Physical Activity within the Secondary School Physical Education Curricula in Southwestern China

Students enrolled in secondary schools often fail to engage in moderate to vigorous levels of physical activity (MVLPA) due to inadequacies in their physical education programs. Physical education teachers (PETs) foster student involvement in MVLPA. Consequently, it becomes imperative to identify and scrutinize factors pertaining to PETs that could influence students’ MVLPA within secondary school settings, an area that has been relatively overlooked in China. To address this gap, the present study delved into MVLPA among secondary school students in southwest China with the following objectives: (i) to assess students’ MVLPA alongside PET characteristics and teaching behaviors during physical education classes; (ii) to explore discrepancies in PET behaviors and characteristics; and (iii) to establish connections between students’ MVLPA and PET behaviors and characteristics during physical education sessions. A questionnaire survey was administered to 54 full-time PETs across nine secondary schools in Chengdu, China, aimed at gathering data on their personal and professional attributes. Additionally, a system for observing fitness instruction time was employed to document PET instructional traits, while accelerometers were utilized to track students’ MVLPA. The study objectives were investigated using multiple statistical analyses. The findings indicate that PETs do not meet the recommended 50% MVLPA time allocation during physical education sessions. Noteworthy patterns emerged, revealing that PETs with 1–5 years of teaching experience allocated less time to student observation and more time to classroom management compared to their counterparts with 6–10 years and over 10 years of teaching experience. Moreover, MVLPA time invested in lessons led by male PETs (B = −3.221) was significantly higher than time spent in lessons led by female PETs, which was attributed to PET gender. Furthermore, students under the tutelage of PETs with 6–10 years of teaching experience (B = 3.101) and those with over 10 years of experience (B = 2.989) exhibited significantly higher MVLPAs than under those with 1–5 years of teaching experience. Additionally, PET attitudes such as observation (B = 1.621) and promoting (B = 1.317) behaviors during physical education sessions were positively correlated with students’ MVLPA. A regression analysis revealed that PET characteristics and behaviors explained 21.3% of students’ MVLPA variance. This study offers insights into PETs’ pivotal role in promoting physical activity. It underscores the ramifications for students’ MVLPA in the Chinese educational context.

Mood profile in men and women of all ages is improved by leisure-time physical activity rather than work-related physical activity

BackgroundThe aim of our study was to determine how six mood indicators (vigour, fatigue, depression, anger, confusion, tension) depend on moderate to vigorous physical activity, walking time and sedentary time at work, after working hours and during leisure time, in men and women of different age groups.MethodsA total of 1,140 individuals aged 18 to 64 years participated in the study. The participants were enrolled in this cross-sectional survey using a snowball sampling method. An online questionnaire was shared through popular social networks and emails within the period October 2019 to June 2020. Mood responses were assessed using The Brunel Mood Scale-LTU. Physical activity was assessed using the long International Physical Activity Questionnaire. Descriptive analysis, a two-way analysis of variance, and linear regression analysis were used to interpret the data.ResultsThe survey results showed that vigour and fatigue correlated significantly only with leisure-time moderate to vigorous physical activity. The present results show a significant positive correlation between women and men moods and leisure-time moderate to vigorous physical activity, the length of time walking to work and back home, and negative correlation between moods and leisure-time sedentary behaviour. However, there was no significant correlation between moods and work-related moderate to vigorous physical activity and household moderate to vigorous physical activity, walking at work, and sitting duration at work.ConclusionsThis study provides theoretical implications of the physical activity paradox, justifying the benefits of moderate to vigorous physical activity practiced in different circumstances. According to the regression analysis, exercising men in all age groups moved the most (had a higher moderate to vigorous physical activity level) during leisure time, the highest work-related moderate to vigorous physical activity was observed in men and women with lower education, and the highest household moderate to vigorous physical activity was observed in older age men and women living in rural areas. Clinicians and leaders at all levels of health care should consider the greater importance of leisure-time physical activity for mental health when choosing the most targeted physical activity recommendations for mood profile improvement in men and women of different age groups.

P478 Fatigue, physical fitness, and physical activity in patients with inflammatory bowel disease

Abstract Background Fatigue is a common and debilitating symptom in patients with Inflammatory Bowel Disease (IBD) with a great impact on quality of life and work productivity. A better comprehension of the contributing factors to fatigue could potentially pave the way for more targeted and effective strategies for managing fatigue in IBD. Fatigue may be associated with lower levels of physical activity and reduced physical fitness. Yet, the interaction between these factors in IBD, measured with validated tests, is not fully understood. Therefore, this study aimed to investigate the association between fatigue and physical fitness and physical activity in patients with IBD. Methods Adult patients with IBD in remission or with mild-to-moderate clinical disease activity with an ASA Physical Status <III were eligible for inclusion. Fatigue was defined as a Checklist Individual Strength-fatigue subscale score ≥35. Patient and clinical characteristics were collected, including age, sex, body mass index, comorbidities, disease duration, disease location and behavior, clinical and biochemical disease activity, smoking status, previous intestinal resection, and medication use. Cardiorespiratory fitness was measured using cardiopulmonary exercise testing to assess the oxygen uptake at peak exercise (VO2peak). Muscular strength (peak torque at 60°/s) and endurance (fatigue rate as percentage decline in peak torque over 30 repetitions at 180°/s) of the knee extensor and flexor muscles were assessed using an isokinetic dynamometer. Objective physical activity data were collected continuously for seven consecutive days utilizing the MOX accelerometer, with activities categorized into sedentary, standing, light (LPA), moderate (MPA), and vigorous physical activity (VPA) levels. Results In total, 50 patients were included, with 17 being classified as fatigued. Fatigued patients had significantly higher BMIs, a higher frequency of clinical disease activity, and a higher prevalence of smoking (Table 1). They also exhibited significantly lower VO2peak (mean [±SD] 28.1 [±7.9] vs. 36.0 [±9.8] mL·kg-1·min-1, p=0.007) and higher knee extensor fatigue rate (mean [±SD] 39.0% [±8.8] vs. 31.1% [±10.4], p=0.010) compared to non-fatigued patients. There was no statistical significant difference in physical activity between fatigued and non-fatigued patients. Conclusion Although physical activity did not differ between patients with and without fatigue, fatigued patients exhibited lower cardiorespiratory fitness and knee extensor muscular endurance. A larger population is needed to further investigate the influence of patient and disease characteristics on this relationship to work towards more targeted and effective strategies for managing fatigue in patients with IBD.

The relationship between internet addiction and physical activity levels of university students in a province in eastern Turkey.

Internet addiction and physical inactivity are often a major public health problem. This study aimed to determine the relationship between internet addiction (IA) and physical activity (PA) levels of university students in a province in eastern Turkey. This cross-sectional study was conducted among 638 students. Internet Addiction Test (IAT), and International Physical Activity Questionnaire (IPAQ) were administered. Chi-square, independent sample t-test, correlation analysis, one-way analysis of variance tests (ANOVA), Tukey HSD test, and multivariate logistic regression analysis were performed. 64.6% of the participants were female, with a mean age of 20.4±2.4 and a mean body mass index (BMI) of 22.3±3.5. 83.4% of the participants were identified as those asymptomatic, 15.2% showed limited symptoms, and 1.4% were pathological internet users according to IAT. A statistically significant difference was found between IAT scores and gender, mother's education level, father's education level, academic success, smoking status, and alcohol use (p < 0.05). According to IPAQ scores, 28.1% of the students were inactive, 56.3% were moderate PA and 15.7% had vigorous PA levels. IPAQ total scores of male participants, smokers, and participants with exercise habits were found to be significantly higher (p < 0.05). The mean score IAT and IPAQ was found to be 30.9±18.9 and 1697.7±1847.0. A negative, significant correlation was found between students' PA and IA levels (p < 0.01). It has been observed that IA negatively affects PA. Seminars, conferences, and panels on the internet and physical activity should be organized for university students.

Association between lifestyle factors and hypertension control in Indonesian primary healthcare settings: A cross-sectional study.

A healthy lifestyle influences hypertension control. However, studies investigating the effects of lifestyle on hypertension remain elusive. This study aimed to analyse the association between lifestyle factors and hypertension control among patients with hypertension. This cross-sectional exploratory study was conducted from June to December 2022 among 265 patients with hypertension from the Pusat Kesehatan Masyarakat. The status of hypertension control was assessed by checking the serial blood pressure. The physical activity (PA) level, sleep quality, stress level and eating pattern were measured using the Global Physical Activity Questionnaire; Pittsburgh Sleep Quality Index; Depression Anxiety Stress Scale-21; and 24-Hour Food Recall Questionnaire, Adolescent Food Habits Checklist and Emotional Eating Scale, respectively. Stepwise binary logistic regression and a generalised linear model were used for the statistical analysis. Approximately 72.2% of the participants had uncontrolled hypertension. The majority showed a low PA level (46%), normal stress level (94.7%), good sleep quality (80%), low caloric intake (95.5%), neutral food habit (55.5%) and low emotional eating (93.2%). Sex (P=0.030), age (P=0.018), PA level (P=0.011), sleep quality (P=0.032) and stress level (P=0.030) significantly influenced hypertension control. Specifically, moderate (odds ratio [OR]=5.868, 95% confidence interval [CI]=3.024-11.798, P=0.000) and vigorous PA levels (OR=2.188, 95% CI=1.026-4.678, P=0.042) were significantly associated with hypertension control. Moderate and vigorous PA levels are lifestyle factors that may play a role in controlling hypertension.

Gender Differences in Students’ Moderate to Vigorous Physical Activity Levels During Primary School Physical Education Lessons: A Systematic Review and Meta-Analysis

Purpose: We aimed to determine gender differences in students’ moderate to vigorous physical activity (MVPA) levels measured in primary school by accelerometry. Methods: Our systematic search (PROSPERO: CRD42023422799) was developed using four electronic databases (from January 2013 to December 22, 2023). Our meta-analysis was conducted based on a random-effects model. Results: The search yielded 6255 manuscripts. Only 24 manuscripts were included in the systematic review, reporting 7550 participants. Finally, 19 manuscripts were meta-analyzed. Our analyses indicated that the mean percentages (SMD = 0.32, 95% CI = 0.24 to 0.40, p &lt; .001) of MVPA in primary school physical education (PE) lessons were 28.75 ± 13.75 for boys and 25.99 ± 12.35 for girls. In addition, the mean minutes (SMD = 0.22, 95% CI = 0.15 to 0.27, p &lt; .001) were 13.75 ± 9.91 for boys and 12.15 ± 8.88 for girls. Students failed to meet the 50% recommendation of MVPA lesson time. Conclusion: Boys spend significantly more time in MVPA than girls during PE lessons in primary school. The findings show the need for methodological changes in PE to reduce this gender gap.

Fizička aktivnost i kvalitet sna kod bolesnika lečenih hroničnim hemodijalizama

Introduction/Aim: Hemodialysis patients are often sedentary and experience a high prevalence of sleep disorders. In this study, we aimed to assess the level of physical activity and quality of sleep among patients on maintenance hemodialysis and assess the relationship between these issues. Material and Methods: Seventy-one hemodialysis patients filled in the International Physical Activity Questionnaire (IPAQ) and the Pittsburgh Sleep Quality Index (PSQI) to assess their level of physical activity and their quality of sleep, respectively. Basic demographic, clinical and treatment-related characteristics were obtained from an electronic medical data system, as well as the results of standard laboratory analyses. The results were analyzed with Student t-test, Pearson chi-square test, linear by linear association, and Spearman correlation. Results: Nearly half of the patients (46.5%) were poor sleepers with an overall PSQI of 5.7 ± 4.4. Older age was significantly associated with worse sleep quality (p=0.019). Patients reported low, moderate or vigorous levels of daily physical activity in 42.3%, 50.7% and 7% of cases, respectively. No statistically significant associations were noted between demographic characteristics, dialysis vintage, comorbidities and the level of physical activity. Distribution of good and poor sleepers was almost identical among patients with low and moderate physical activity (47% vs 53% and 50% vs 50% respectively), whereas patients with vigorous activity were mostly good sleepers (20% vs 80%), but the difference was not statistically significant (p=0.591). Conclusion: We observed no statistically significant association between the level of physical activity and quality of sleep in this cohort. Further research with a larger sample might additionally elucidate this issue.

Physical activity and verbal memory performance: Mediating effects of resting-state brain activity.

Verbal short-term and long-term memory are crucial neuropsychological functions involved in core cognitive abilities. They constitute vital components of subjective well-being and academic achievement. To date, there is limited research on the association between regular physical activity and memory abilities during young adulthood. The Individual Alpha Peak Frequency (IAPF) contributes to various cognitive abilities and also appears to be sensitive to physical activity. Consequently, the IAPF has the potential to underlie the association between physical activity and verbal memory. We examined the direct relation of physical activity and verbal memory, and the potential indirect relation via IAPF in young adults. Regular physical activity was assessed via accelerometry on seven consecutive days in 115 participants (N=115, 48% female) aged 18-35 years (M=24.1, SD=3.8). In addition, verbal memory performance was assessed using an immediate and delayed free-recall task. Brain activity during rest was recorded with EEG, and IAPF was extracted for mediation analyses. Path analysis revealed pronounced sex differences in the association between physical activity, IAPF, and verbal memory performance. Exclusively in female participants, higher vigorous physical activity levels were associated with better recall performance. In contrast, no association of physical activity and memory was found in male participants. However, being more physically active was related to a higher IAPF exclusively in male participants. Physical activity shows differential associations between IAPF and verbal memory in male and female participants. However, the lack of a mediating role of IAPF suggests that this neurophysiological marker cannot explain these specific associations in young adults.

Dissecting the causal relationship between moderate to vigorous physical activity levels and cognitive performance: a bidirectional two-sample Mendelian randomization study.

Recent studies increasingly suggest that moderate-to-vigorous physical activity (MVPA) impacts cognitive risk. However, the bidirectional nature of this relationship warrants further exploration. To address this, we employed a Mendelian randomization (MR) approach, analyzing two distinct samples. These analyses utilized published genome-wide association study (GWAS) summary statistics for MVPA (n = 377,234) and cognitive performance (n = 257,841). Our primary method was the inverse variance weighted (IVW) model with random effects, aiming to deduce potential causal links. Additionally, we employed supplementary methods, including MR Egger regression, Weighted median, Weighted mode, and Simple mode. For sensitivity analysis, tools like the MR Egger test, Cochran's Q, MR PRESSO, and leave-one-out (LOO) were utilized. Our findings indicate a decrease in cognitive risk with increased MVPA (Odds Ratio [OR] = 0.577, 95% Confidence Interval [CI]: 0.460-0.723, p = 1.930 × 10-6). Furthermore, enhanced cognitive levels corresponded to a reduced risk of inadequate MVPA (OR = 0.866, 95% CI: 0.839-0.895, p = 1.200 × 10-18). In summary, our study demonstrates that MVPA lowers cognitive risk, while poor cognitive health may impede participation in MVPA. Overall, these findings provide valuable insights for developing personalized prevention and intervention strategies in health and sports sciences.

Physical Activity Patterns Within Dementia Care Dyads.

Previous research has explored the physical activity habits of people with dementia and their family carers separately, with little consideration of how physical habits are associated within dyads. In this observational study, we sought to explore the relationship between people with dementia and their carers' physical activity, at a group level and at a dyadic level. Twenty-six participant dyads (persons with dementia and their carer spouses) were asked to wear an accelerometer for 30days continuously. Comparisons were made at a group level and a dyadic level. People with dementia did not participate in significantly more moderate to vigorous physical activity (M = 15.44min/day; SD = 14.40) compared with carers (M = 17.95min/day; SD = 17.01). Within dyads, there were moderately strong associations between daily moderate to vigorous physical activity (r = .48-.54), but not with overall activity levels (r = .24). Despite physical activity habits remaining relatively low within people with dementia and carers, respectively, moderate to vigorous physical activity levels appear to be correlated within dyads. Understanding mutual influence on physical activity levels within dyads is an important pathway to promote an active lifestyle.

Association between physical activity and taste-The advantage of increased intensity for some but not all individuals.

Taste is a key sensory modulator of energy intake, and while the effects of acute physical activity (PA) on taste have been recently confirmed, its chronic effects remain poorly documented. Data were extracted from the NHANES database, including salty and bitter taste tests, moderate PA (MPA) and vigorous PA (VPA) levels, and anthropometric data. Binary logistic regressions were conducted, and odds ratios (ORs) represent the association between physical activity level and successful taste tests. 3,114 participants (51.5% women, mean age 58.5±11.9 years, mean BMI 29.5±7.0 kg/m2) were analyzed. For the tongue tip test, the frequency of VPA was associated with a better score for the bitter and total taste test, while duration of VPA was associated with a better score for the bitter, salty, and total taste test (OR [1.01-1.06], p<0.05). For the whole mouth test, MPA frequency improved the bitter taste score (OR = 1.06, p = 0.01) while VPA frequency and duration were associated with better scores for bitter, salty, and total taste tests (OR [1.01-1.15], p<0.05). These findings were distinctively influenced by weight status and gender, with males and individuals without obesity mainly beneficiating from an active lifestyle. This study underlines the link between PA, particularly its frequency and intensity, and improved taste preservation. These findings emphasize the potential benefits of regular VPA for optimizing taste perception, although questions remain regarding the advantages for individuals with obesity and the lack of association observed in women who might already have a preserved profile.

National Trends in the Prevalence of Screen Time and Its Association With Biopsychosocial Risk Factors Among Korean Adolescents, 2008–2021

PurposePrior studies suggested an increase in screen time among adolescents during the COVID-19 pandemic; however, due to limited sample size and a short-term observation period, these associations are inconclusive and inconsistent. Thus, we aimed to compare screen time during the pandemic and the long-term trend through a Korean large-scale and long-term study of one million adolescents. MethodsData from 2008 to 2021 on 913,191 Korean adolescents aged 12–18 years were obtained via a nationwide, large-scale, and serial study. We investigated the change of screen time use over time and the change in trend before and during the pandemic (2008–2019 vs. 2020–2021) by using weighted linear regression model with estimates of β-coefficients and 95% confidence intervals (CIs). Moreover, we analyzed the differences in vulnerability of biopsychosocial factor before and during the pandemic. ResultsA total of 913,191 adolescents were included in this analysis. During the pandemic, the overall screen time of Korean adolescents significantly increased compared to the expected based on the prepandemic period during the pre–COVID-19 period (weighted screen time before the pandemic [133.24 min/day; 95% CI, 132.08–134.40] vs. during the pandemic [303.66 min/day; 95% CI, 300.59–306.73]; βdiff 0.331; 95% CI, 0.311–0.351). Comparing before and during the pandemic, potential risk factors associated with screen exposure included female sex, sadness, suicidal thoughts, alcohol consumption, low educational level of parents, low level of vigorous physical activity, middle school students, and low household income. DiscussionThrough large-scale nationwide study, this study described the 14-year trend of screen time among Korean adolescents. In the era of COVID-19, the prevalence of screen exposure has been increasing more rapidly than before at the population level. Also, the pandemic amplified the differences in screen time across grade, sex, sadness, suicidal thoughts, smoking, alcohol consumption, education level of parents, physical activity, and household income groups.

Exploring sex differences regarding the mediation of the relationship between depression and quality of life via moderate and vigorous physical activity in old age: A longitudinal study

PurposeDepression (DEP) is common in old age and is associated with poor quality of life (QoL) as well as a poor level of physical activity (PA). The objective of this study was to investigate the association between DEP, moderate physical activity (MPA), and vigorous physical activity (VPA) with QoL, as well as longitudinally examine in depth whether MPA and VPA mediate the relationship between DEP and QoL in men and women aged ≥50 years residing in 12 European countries. Materials and methodsLongitudinal mediation analysis, that included 20,647 individuals (8042 men) aged >50 years, who responded to the fourth (in 2011), fifth (in 2013), and sixth (in 2015) wave of the Survey of Health, Ageing and Retirement in Europe (SHARE). The analyzed variables were DEP (EURO-D scale), QoL (CASP-12), and self-reported MPA and VPA in daily life. ResultsComparatively, women indicated a higher DEP score, lower perception of QoL, and levels of MPA and VPA. In both sexes, DEP and QoL indicated a negative association (p < 0.001), and MPA and VPA were positively associated with QoL (p < 0.001). Mediation analysis showed that DEP directly affected MPA and VPA 2 years later and QoL 4 years later. MPA and VPA partially mediated the longitudinal relationship between DEP and QoL over 4 years. Regarding sex, there were no differences between the longitudinal measurement paths. ConclusionPolicies should be created to encourage the older European population to reach adequate physical activity levels to improve QoL and combat depressive symptoms.

Smoking, Physical Activity, and Hypertension Incidence Among Older Adults in Malang, Indonesia

Hypertension is a crucial health concern that requires attention, and it can be influenced by factors such as smoking and physical activity. According to a study conducted at Lawang Health Center, Malang, Indonesia, in 2020, 13.5% of the population in RW 05, Bedali Village, Malang, suffered from hypertension. It was one of the top three prevalent diseases in the village, especially among individuals aged over 69 years. The objective of this research was to examine the relationship between smoking, physical activity, and the occurrence of hypertension among older adults in RW 05, Bedali Village, Lawang, Malang. The study employed a case-control analytic observational method, involving 25 cases and 25 controls within the older adult age group (&gt;45 years). The participants consisted of 50 individuals, including 23 men and 27 women. Among the respondents, 23 were smokers, while 27 were non-smokers. Additionally, 25 respondents engaged in light physical activity, whereas 25 respondents had moderate to vigorous physical activity levels. The analysis indicated a significant correlation between smoking, physical activity, and the prevalence of hypertension among older adults in RW 05, Bedali Village, Lawang, Malang, with a p-value of 0.005 for each factor.

Abstract 15439: Association of Vigorous Physical Activity With Cardiovascular Disease and Mortality in 136,766 Adults From High-Income, Middle-Income and Low-Income Countries: The Prospective Urban Rural Epidemiological (PURE) Study

Background: It’s recommended adults get 150-300 minutes of moderate physical activity (MPA) and/or 75-150 minutes of vigorous physical activity (VPA) per week. Some studies have found high VPA to be protective and others found it to be harmful. These studies have been conducted in high-income countries using recreational VPA as the exposure of interest. Purpose: To evaluate the effects of VPA with all-cause mortality, and cardiovascular disease (CVD) in countries at different economic levels. Methods: Participants aged 35-70 years were recruited from 21 countries at various stages of economic development. Physical activity (total, walking, MPA, VPA, as well as recreational vs. non-recreational PA) was assessed using the International Physical Activity Questionnaire. Primary clinical outcomes were the composite of mortality plus major CVD (CVD mortality, myocardial infarction, stroke, or heart failure) and mortality. A total of 136,766 participants without baseline CVD, cancer, and HIV were analyzed. Models were adjusted for age, sex, urban/rural residency, country income level, education, household wealth index, smoking, baseline chronic diseases, physical impairments, MPA, walking and centre as a random effect. Results: During the median follow-up of 11.5 (8.6-12.4) years, there were 9846 deaths and 7900 major CVD events. The median min/wk (IQR) for total PA, walking, MPA and VPA were 690 (250-1530), 40 (0-420), 330 (75-860), 0 (0-0). The mean VPA was 103±390 min/wk. Compared to no VPA, 150-299 minutes per week of VPA was associated with reduced risk for the composite outcome and mortality, HR = 0.82 (0.73,0.92) and 0.74 (0.64,0.86), respectively. When VPA was stratified into either recreational or non-recreational VPA, recreational VPA displayed a U-shape relationship, such that higher levels were associated with less benefit. Increasing non-recreational VPA continued to confer reduced risk even above 3000 min/wk. At any amount of moderate PA, higher VPA was associated with reduced risk for the composite outcome and mortality. Conclusion: Higher levels of VPA were associated with reduced risk for mortality and major CVD events up to more than 40 times the minimum recommended amount. At no point did VPA confer an increased risk.

Abstract 17225: Association Between Moderate and Vigorous Physical Activity on Long-Term Heart Failure Risk: The Cooper Center Longitudinal Study

Introduction: Regular physical activity (PA) is associated with a lower risk of heart failure (HF). However, the relative contributions of moderate and vigorous intensity exercise on HF risk is still unclear. We characterized the association between moderate (MPA) and vigorous physical activity (VPA) on the long-term risk for HF. Methods: We included participants free from baseline coronary disease in the Cooper Center Longitudinal Study (CCLS) who were Medicare eligible at age 65 years. PA was measured from a self-report instrument that included duration (minutes/week) and intensity of exercise (METs), with moderate intensity as 3-6 METs and vigorous intensity as 6 METs. Incident HF was defined as a HF hospitalization event (primary diagnosis) from Medicare claims files. MPA and VPA were considered separately as continuous variables. The association between baseline PA and incident HF was evaluated by Cox proportional hazards models adjusted for standard HF risk factors. Results: Of 32,322 individuals (mean age 50.9, 74.2% men), the mean number of hours/week of MPA and VPA was 1.2 and 1.4, respectively. 56.42% reported zero MPA and 42.6% reported zero VPA. Higher levels of VPA, but not MPA, were associated with a lower burden of HF risk factors. After 275,373 person-years of follow-up, we observed 954 incident HF hospitalizations. MPA was not significantly associated with HF risk in either model. VPA was inversely associated with HF risk in age-adjusted models. After multivariable adjustment, VPA was not associated with HF risk (see table). Conclusions: Midlife VPA, but not MPA, was associated with a lower risk for HF. However, after additional adjustment for traditional HF risk factors, the association between higher VPA and HF risk was no longer significant. These findings suggest that the inverse association between midlife VPA and long-term HF risk may be mediated by a more favorable risk factor profile.

The Influence of Marriage and Cohabitation on Physical Activity Among Middle-Aged and Older People.

Using data from a nationally representative longitudinal study, Midlife in the United States (waves 1-3; N = 1113; aged 49-93), this study investigated whether partnered living status (partnered vs. non-partnered) and partnered living quality (support/strain from partner, partner disagreements) were associated with physical activity in middle-aged/older adults. Regressions were performed to test the effect of change or stability in partnered living status across three waves and relationship quality on the frequency of moderate and vigorous physical activity at Wave 3. Subjects who changed from non-partnered to partnered living had the highest moderate and vigorous physical activity levels. Partner support was positively associated with moderate physical activity (β = .50, p < .01), and partner disagreement was negatively associated with vigorous physical activity (β = -.27, p < .01). Results suggest that partnered living status and quality can influence physical activity among the aging population. Physical activity interventions among older adults may benefit from including social support as a key component.

A Pilot Study of Exercise Training for Children and Adolescents With Inflammatory Bowel Disease: An Evaluation of Feasibility, Safety, Satisfaction, and Efficacy.

Children with inflammatory bowel disease (IBD) experience extraintestinal side effects including altered body composition, impaired muscle strength, and aerobic capacity. Exercise training may remedy these issues. To assess the feasibility, safety, participant satisfaction, and efficacy of a training program for youth with IBD. Children with IBD completed 16weeks of training (2 supervised + 1 home sessions per week). Feasibility was assessed by tracking recruitment, adherence, and compliance rates. Safety was assessed by tracking symptoms and adverse events. Posttraining interviews gauged satisfaction. Circulating inflammatory markers, body composition, muscle strength, aerobic fitness, and habitual physical activity were measured at baseline, midtraining (8wk), and posttraining. Eleven youth were recruited and 10 completed the study. Participants adhered to 28 (1) of 32 prescribed supervised sessions and 8 (4) of 16 prescribed home sessions. There were no adverse events, and overall feedback on training was positive. Posttraining, we observed an increase in lean mass (+2.4 [1.1]kg), bone density (+0.0124 [0.015] g·cm-2), aerobic fitness (+2.8 [5.7] mL·kgLM-1·min-1), and vigorous physical activity levels (+13.09 [8.95]min·h-1) but no change in inflammation or muscle strength. Supervised exercise training is feasible, safe, and effective for youth with IBD and should be encouraged.

O.5.1-5 Influence of the parental perception of the neighborhood environment on physical activity and active school commuting in Ecuadorian children

Abstract Purpose Physical inactivity among children is considered a multidimensional problem. This study examines the relationships between parents' perceptions of the neighborhood environment with physical activity (PA) and active school commuting among urban children from Cuenca-Ecuador. Methods A cross-sectional study was conducted between October 2018 and March 2019 among 1028 children (8 to 12 years old) and their parents/guardians. Children's PA levels were objectively measured using accelerometers (Actigraph). Parent's perceptions of their neighborhood aesthetics, traffic, and crime hazards were assessed using the Neighborhood Environment Walkability Scale for Youth (NEWS-Y) parent version. Active school commuting (ASC) was evaluated using a validated tool applied to the children. Children who reported walking or using a bicycle to commute to and from school five days a week were classified as active commuters. Multivariate ordinary least squares and logistic regressions models were performed to determine associations between parents' perceptions of the neighborhood environment with PA and ASC, respectively. Results Complete data were available from 711 children (52% female) and 521 parents. The parental perceptions of the neighborhood aesthetics (Mean: 2.68; DE:0.75) and traffic hazards (Mean: 2.44; DE:0.44) were not associated with children's physical activity. Neighborhood crime safety (Mean:2.64; DE:0.74) score was negatively associated with the children's vigorous physical activity (Mean:14.50 minutes/day; DE:8.66) level (β = -1.52 minutes/day; DE = 0.52; p &amp;lt; 0.004). After adjusting for walking distance and car ownership, parental perception of neighborhood aesthetics, traffic, and crime hazards were not associated with ASC. Conclusions Crime hazard was identified as the main barrier to children's vigorous PA. The neighborhood environment seems not to be associated with children's ASC. Future studies should identify the determinants for ASC, and comprehensive policies are urgently needed to overcome crime hazards in Ecuador Funding source Universidad de Cuenca, Universidad Politécnica Salesiana Sede Cuenca.
