Nonlinear dose-response association of moderate-to-vigorous physical activity with hyperuricemia in US adults: NHANES 2007-2018.

The relationship between physical activity and hyperuricemia (HUA) remains inconsistent, and the dose-response association between moderate-to- vigorous physical activity (MVPA) level and HUA still unclear. In this study, we aimed to investigate the dose-response association of MVPA with HUA, and to explore an appropriate range of MVPA level for preventing HUA. Data from the US National Health and Nutrition Examination Survey (NHANES) 2007-2018 were used, including 28740 non-gout adult Americans. MVPA level was self-reported using the Global Physical Activity Questionnaire and serum uric acid was measured using timed endpoint method. The dose-response relationship between MVPA level and HUA was modeled with restricted cubic spline analysis. Logistic regression analysis were applied to estimate odd ratios (ORs) and 95% confidence intervals (CIs) of the relationships between MVPA level and HUA. A total of 28740 adults were included in the study (weighted mean age, 47.3 years; 46.5% men), with a prevalence rate of HUA was 17.6%. The restricted cubic spline functions depicted a general U-shaped relationship between MVPA level and HUA. The MVPA level of 933 and 3423 metabolic equivalent (MET) -min/wk were the cut-off discriminating for the risk of HUA. Participants with MVPA levels in the range of 933-3423 MET-min/wk had lower risk of HUA and they had the lowest risk when MVPA levels at around 1556 MET-min/wk. Compared with the moderate-activity group (600-2999 Met-min/wk), the low-activity group (< 600 Met-min/wk) had a greater risk of HUA (OR, 1.13 [95%CI, 1.02-1.26]) after fully adjusting for potential confounders. Compared with the moderate MVPA level, the low MVPA level was associated with the higher risk of HUA. And there may be a U-shaped dose-response relationship between MVPA level and HUA. When MVPA level was approximately 933-3423 MET-min/wk, the risk of HUA may at a lower level and the risk reached the lowest when MVPA level at around 1556 MET-min/wk.

Relationships between moderate vigorous physical activity, motor- and health-related fitness and motor skills in children

Background: Childhood is an important transitional period for the development of healthy physical activity (PA) behaviours, so it is important to understand its impact on a healthy lifestyle.Aim: This study aimed to determine the influences of sex, socioeconomic status (SES) and body composition (BC) on the relationships between PA, motor skills, motor- and health-related physical fitness in 5–8-year-olds.Setting: Participants were a subsample consisting of 299 children (150 boys, 149 girls, mean age 6.83 ± 0.96 years) from the Exercise, Arterial Modulation and Nutrition in Youth South Africa study (ExAMIN Youth SA).Methods: Anthropometric measures, health-related physical fitness (HRPF), motor-related physical fitness (MRPF), objectively measured PA and demographic information were determined.Results: Only 66% achieved the recommended 60 min of daily moderate vigorous physical activity (MVPA) with 19% classified as having unhealthy body composition (11% overweight, 8% obese). Fat-free mass and SES revealed small-to-moderate influences on the relationship between MVPA, standing broad jump (SBJ; r = 0.32), predicted VO2max (r = 0.28) and beep levels (r = 0.22). For MRPF, the quality of running (r = 0.12) and balancing were associated with MVPA. Adjusting for sex, BC and SES in the relationship between PA with HRPF and MRPF, reductions in most correlations were observed.Conclusion: Moderate vigorous physical activity levels were positively associated with HRPF, MRPF and some motor skills in 5–8-year-olds. Socioeconomic status (lower parental income, employment and education negatively influenced the association between MVPA and fitness [beeps, SBJ, O2max]).Contribution: This study provides knowledge with regard to the use of accelerometer for baseline data for PA, MRPF, HRPF as well as motor skills in South African children.

The association of resilience and physical activity in older adults: cross-sectional analyses from the NICOLA study

Abstract Aim As more of the world’s population are living longer, supporting the mental and physical health of older adults is becoming increasingly important in public health. Resilience is a dynamic process encompassing positive adaptation in the face of adverse experiences that would otherwise lead to poor outcomes. The aim of the study is to explore the association between physical activity and resilience in older adults. Subject and methods The data used in this study was taken from the results of the Self Completed Questionnaires and Computer Assisted Personal Interviews from the Northern Ireland Cohort for the Longitudinal Study of Ageing. A secondary analysis was conducted on a sample of 4040 participants to examine the association between resilience (Brief Resilience Scale) and on moderate/vigorous physical activity (International Physical Activity Questionnaire – Short Form) through chi-square and Mann–Whitney U tests and an ordinal regression being conducted. Results Data was included for 4040 participants, of whom 90% did not meet the recommended moderate physical activity guidelines. The findings of this study indicated that higher resilience levels are associated with higher levels of moderate and vigorous physical activity levels. Conclusion Worryingly, a large percentage of the older adult population are not sufficiently active and this is something that needs to be addressed. The findings suggest that with these low levels of physical activity, interventions should be created to target this population.

Sports participation in childhood and adolescence and physical activity intensity in adulthood.

The aim of the present study was to analyze the association between sports participation in childhood and adolescence and the practice of physical activity at different intensities in adulthood, and to verify if some sports participation characteristics such as number of sports; type of sport (individual, collective or a combination of both) and total estimated sports participation time are associated with the different physical activity intensities in adulthood. This is a cross-sectional study. This study included 129 young adults of both sexes aged 18-25 years. Sports participation in childhood (7-10 years) and adolescence (11-17 years) was retrospectively estimated through specific questionnaire. Light, moderate, vigorous and moderate to vigorous intensity physical activity was objectively estimated by accelerometers. To verify the association between SP in childhood and adolescence and BP intensities in adults, multiple linear regression was adopted, with 5% significance. Analyses showed that, in females, sports participation in childhood (β = 0.315; R2 = 0.14; P = 0.020) and persistence in sports participation (β = 0.364; R2 = 0.18; P = 0.007) were positive predictors of vigorous physical activity in adulthood. In addition, the comparison according to the specificities of the sport practice, indicated that participation in two or more sports in childhood, one sport and collective sports in adolescence and at least one year of sports participation throughout childhood and adolescence were associated with longer time in vigorous physical activity intensity and MVPA (minutes/day) in adult females (P < 0.05). It could be concluded that sports participation indicators in childhood and adolescence were considered predictors of vigorous physical activity in adult females. In addition, number of sports, type of sport and practice time in childhood and adolescence seem to predict vigorous and moderate to vigorous levels of physical activity for adult females.

Association between movement behavior patterns and cardiovascular risk among Chinese adults aged 40–75: a sex-specific latent class analysis

BackgroundCardiovascular disease (CVD) is a major global health threat, particularly in China, contributing to over 40% of deaths. While sleep behaviors, sedentary behaviors, and physical activities are recognized as independent lifestyle risk factors for CVD, there remains limited understanding of specific movement behavior patterns and their CVD risks, especially considering sex-specific differences. This study examines movement behavior patterns among Chinese adults (40–75) and their associations with cardiovascular risk, with a focus on sleep, physical activity (PA), and sedentary behavior (SB).MethodsData pertaining to 13,465 male participants and 15,613 female participants, collected from the Chronic Disease and Risk Factor Surveillance Survey in Nanjing from February 2020 to December 2022. The latent class analysis method was employed to identify underlying movement patterns across sexes. Multinomial logistic regression models assessed CVD risk, and the China-PAR model calculated 10-year risk.ResultsThree male and four female movement patterns emerged. Active Movers (17.10% males, 5.93% females) adhered to PA recommendations but had poorer sleep quality. Moderate Achievers (61.42% males, 45.32% females) demonstrated moderate behavior. Sedentary Sleepers (21.48% males, 10.20% females) exhibited minimal PA but good sleep. Female Moderate Physical Activity (MPA) Dominant Movers demonstrated a prevalent adherence to recommended MPA levels. Active movers had the lowest CVD risk. After adjusting for potential confounders, moderate achievers (OR = 1.462, 95% CI 1.212, 1.764) and sedentary sleepers (OR = 1.504, 95% CI 1.211, 1.868) were both identified as being associated with a high-risk of cardiovascular diseases (CVDs) compared to active movers in males, demonstrating a similar trend for intermediate risk. Such associations were not statistically significant among females.ConclusionsOur study revealed sex-specific movement patterns associated with CVD risks among middle-aged Chinese adults. We suggest that adopting an active movement behavior pattern, characterized by meeting or exceeding recommended levels of vigorous physical activity (VPA) and reducing sedentary behavior, is beneficial for all middle-aged adults, particularly males. An active lifestyle could help counteract the adverse effects of relatively poor sleep quality on the risk of developing CVD in this population. Integrating sleep, PA, and SB information provides a holistic framework for understanding and mitigating CVD risks.

A Field Study to Assess Physical Activity Levels During Weekdays Among Students in the First Cycle and its Relationship with Lower Limb Muscle Strength

This study aimed to assess physical activity levels during 3 school days among first cycle students and its relationship with lower limb muscle strength. Twenty-eight students from the Governor of Muscat were participated in this study, (age: 11.8±0.3 years, height: 9.0±148 cm, mass Body: 14.5±34.8 kg, BMI: 5.3±19.2 kg.m-2 To assess physical activity levels, the ActiGraph GT3X device was used for 3 school days during the week (from 8:00 am to 12:00 pm, daily). All participating performed two tests of lower limb muscle strength (CMJ - FCM). Study results showed that the average physical activity levels of students during 3 school days were (455.9± 56.7minutes) and (26.3±6.6 minutes) for both sedentary physical behavior (SPA) and high-intensity physical activity (VPA), respectively. The results also revealed that the level of moderate and vigorous physical activity level (MVPA) during 3 days of school reached (67.9 ±17.01minutes), which is approximately (22.6 minutes per day), meaning that there was a noticeable decrease in the levels of physical activity practiced during school days (3 days). per week for first cycle students. The results also showed that there was no relationship between all physical activity levels (SPA, LPA, MPA, VPA, MVPA) and lower limb muscle strength tests (CMJ - FCM) among the students (0.05&lt;p).

Should organized sport characteristics be considered as a strategy for meeting physical activity guidelines in children?

A clearer understanding of the relationships between specific sport context with overall physical activity (PA) and sedentary time (ST) may contribute to the development of more accurate preventive strategies to increase children's engagement in PA. This study aimed to examine how different organized sports contributed to children's daily PA and ST. PA was measured for seven days via accelerometers, in 410 children aged 6-10 years (49.8% boys). Of those, 332 (53.0% boys) were engaged in an organized sport and were further considered for statistical analyses. Parents reported children's sport participation (e.g. which sport, number of times per week, duration). The sports were classified into: indoor vs. outdoor; individuals vs. team; combat vs. individual aesthetic vs. racing vs. invasion. Children's height and weight were objectively collected. Multiple one-way analyses of covariance were used to examine the effects of sport characteristics on PA and ST. A linear regression, adjusted for children's sex, age, body mass index and father's educational level, determined the relationship between being involved in multiple PA and sedentary behaviours with Moderate to Vigorous PA (MVPA) levels. Although engaged in an organized sport, only 30% of the children achieved the PA recommendations. Sport (compared with active commute and active play) was the best contributor to daily MVPA. Outdoor sports (vs. indoor) contributed the most to vigorous PA (VPA) and MVPA. Team sports (vs. individual) were significantly associated with lower ST. Children in combat sports accumulated more VPA and MVPA, while those in racing sports showed a higher ST. Sport participation alone does not guarantee children will reach the PA guidelines, and the type of sport can influence children's PA levels. Gender-stereotypes in sports may prevent girls from achieving their 60 minutes of MVPA daily.

Walk or be walked by the dog? The attachment role

BackgroundThe human-animal bond has been recognized as having positive effects on the health and well-being of both humans and pets. The present study aims to explore the influence of attachment on physical activity (PA), lifestyle, and health outcomes of dog owners (DO), highlighting the mutual benefits resulting from the relationship between DO and dogs.MethodsThirty-eight DO and their dogs participated in this study. Socio-demographic data, the Self-Rated Health (SRH), FANTASTICO Lifestyle Scale, and the Lexington Attachment Pet Scale (LAPS) were assessed. PA was measured in both the DO and the dogs, using an ActiGraph GT3X accelerometer in the context of daily routine. Descriptive statistics and Spearman rank correlation analyses were performed to examine the associations between LAPS, PA levels, socio-demographic variables, lifestyle behaviors, and SRH.ResultsSignificant correlations were found between the dog owners’ light-level PA and the pets’ vigorous level of PA (rho = 0.445, p = 0.01). Furthermore, the importance of the pets’ health (rho = -0.785, p = 0.02) and the LAPS subscales, namely proximity (rho = 0.358, p = 0.03), and attachment (rho = 0.392, p = 0.01), were related to taking the pet for a walk. Regarding lifestyle, DO with a healthier lifestyle had a better self-assessment of their health using the SRH (rho = 0.39, p = 0.02). Moreover, DO with better lifestyles also exhibited greater concern for their pet’s health (rho = 0.398, p = 0.01).ConclusionsThis study emphasizes that individuals who adopt healthier habits tend to perceive themselves as healthier and exhibit greater concern for their pets’ health. The attachment between DO and dogs is important in promoting healthy lifestyle behaviors and engagement in PA. Our results highlight that the presence of a dog is associated with a higher level of PA in DO, depending on the strength of the human-animal bond.

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 &amp;lt;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.

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.
