Project description:ObjectivesAlthough socioeconomic status (SES) has been shown to be an important determinant of physical activity (PA) in adults, the association in children and adolescents remains less consistent based on evidence from western developed countries. The purpose of this study, therefore, is to investigate associations between SES and PA among Chinese children and adolescents.MethodsA cross-sectional study was conducted with a self-reported questionnaire in China. The multi-stage stratified cluster sampling method was used, and 2,955 children and adolescents (8-17 years old, 53.4% girls) were enrolled in this study. SES was assessed by measuring parental education levels, perceived family wealth, and Family Affluence Scale II (FAS II). PA was assessed by reliable and valid items from the Health Behavior School-aged Children Surveillance questionnaires. Descriptive statistics were used to report sample characteristics, including demographic characteristics, levels of PA, and SES. The Chi-square test was applied to analyze the differences of PA in gender and school period. Binary logistic regression was used to analyze the association between SES and PA among children and adolescents.ResultsOverall, 10.4% of children and adolescents accumulated moderate-to-vigorous physical activity (MVPA) at least 60 min per day. Boys were more physically active than girls (14.1% vs. 7.2%, p < 0.001). Higher socioeconomic status was positively associated with higher physical activity levels among children and adolescents, especially using FAS and mother education level as SES measures. The association between SES and PA varied by gender and grade group, and the effects of SES are also different on weekdays and weekends.ConclusionThis study found socioeconomic disparities in PA among Chinese children and adolescents, and showed the importance of targeting children and adolescents with low SES intervention priority. Based on these research findings, it is suggested that SES, especially for FAS and mother education level, should be considered when designing and implementing the promotion of regular PA in children and adolescents. Health policymakers may use this information to develop interventions to reduce health inequalities among children and adolescents in the future.

Project description:PurposeThe objective of this study was to examine the associations between parental support for physical activity (PA) and levels of moderate-to-vigorous physical activity (MVPA) among Chinese school children.MethodsStudy participants were 81,857 school-aged children (aged 9-17 years; mean age = 13 years; 49.0% boys) and their parents or guardians who took part in the 2016 Physical Activity and Fitness in China-The Youth Study project. The independent variables included various forms of parental support for PA ascertained through a survey completed by parents or guardians. The dependent variable was the children's average MVPA in minutes per day by self-report. Structure equation modeling was used to examine the associations between parental support for PA and children's MVPA minutes.ResultsThe overall mean for MVPA participation time for the child participants was 48.82 ± 28.71 min/day. Significant associations between various forms of parental support and MVPA among children were found. Parental encouragement, accompanying, financial support, involvement, and role modeling for PA were positively associated with a high level of student MVPA participation. Parental PA knowledge-sharing was not associated with MVPA. The patterns of the associations were similar across sex, residence locale (i.e., urban and rural), and school grades (primary, junior middle, and junior high schools).ConclusionFindings from this study suggest that, among Chinese school children, parental support for PA is important in promoting and facilitating children's participation in MVPA.

Project description:BackgroundAsthma and obesity are highly prevalent in children, and are interrelated resulting in a difficult-to-treat asthma-obesity phenotype. The exact underlying mechanisms of this phenotype remain unclear, but decreased physical activity (PA) could be an important lifestyle factor. We hypothesize that both asthma and overweight/obesity decrease PA levels and interact on PA levels in asthmatic children with overweight/obesity.MethodsSchool-aged children (n = 122) were divided in 4 groups (healthy control, asthma, overweight/obesity and asthma, and overweight/obesity). Children were asked to perform lung function tests and wear an activity monitor for 7 days. PA was determined by: step count, active time, screen time, time spent in organized sports and active transport forms. We used multiple linear regression techniques to investigate whether asthma, body mass index-standard deviation score (BMI-SDS), or the interaction term asthma x BMI-SDS were associated with PA. Additionally, we tested if asthma features (including lung function and medication) were related to PA levels in asthmatic children.ResultsAsthma, BMI-SDS and the interaction between asthma x BMI-SDS were not related to any of the PA variables (p ≥ 0.05). None of the asthma features could predict PA levels (p ≥ 0.05). Less than 1 in 5 children reached the recommended daily step count guidelines of 12,000 steps/day.ConclusionWe found no significant associations between asthma, overweight and PA levels in school-aged children in this study. However, as PA levels were worryingly low, effective PA promotion in school-aged children is necessary.

Project description:BackgroundIn today's society, commercial physical activity apps (eg, Fitbit and Strava) are ubiquitous and hold considerable potential to increase physical activity behavior. Many commercial physical activity apps incorporate social components, in particular app-specific communities (allowing users to interact with other app users) or the capacity to connect to existing social networking platforms (eg, Facebook or Instagram). There is a growing need to gain greater insights into whether commercial physical activity apps and specific components of these apps (social components) are beneficial in facilitating physical activity.ObjectiveThis study aimed to examine the relationship between the use of commercial physical activity apps and engagement in physical activity. The social components of commercial physical activity apps (app-specific communities and existing social networking platforms) were also explored. This involved isolating specific features (eg, sharing, providing, and receiving encouragement, comparisons, and competitions) of app-specific communities and existing social networking platforms that were most valuable in facilitating physical activity.MethodsA cross-sectional web-based survey was conducted. Participants were 1432 adults (mean age 34.1 years, 1256/1432, 88.00% female) who completed measures assessing physical activity, the use of commercial physical activity apps, and engagement with app-specific communities and existing social networking platforms.ResultsOverall, 53.14% (761/1432) of the sample reported engaging with a commercial physical activity app. The most commonly used apps were Fitbit (171/761, 22.5%), Strava (130/761, 17.1%), and Garmin (102/761, 13.4%). The use of physical activity apps was significantly associated with physical activity. Notably, the use of app-specific communities and existing social networking platforms facilitated significantly greater engagement in physical activity. The features of app-specific communities that were most beneficial in promoting engagement in physical activity were providing encouragement to a partner, receiving encouragement from close friends and family, and engaging in competitions with members of public app-specific communities. In relation to existing social networking platforms, sharing physical activity posts predicted engagement in physical activity.ConclusionsThe findings indicate that app-specific communities and existing social networking platforms are components of apps that are fundamental in facilitating physical activity. They further suggest that commercial physical activity apps afford high population level reach and hold great potential to promote engagement in physical activity, an important public health consideration.

Project description:IntroductionPhysical activity (PA) is believed to play an important part in many aspects during childhood and adolescence, especially cardiorespiratory fitness and cardiometabolic health. However, whether different levels of PA in daily life influence the structure or function of heart in school-aged children remains unknown. We aimed to investigate the association between PA and cardiovascular parameters in 7-year-old children.MethodsFollow-up data from the Shanghai Prenatal Cohort Study and the Shanghai Birth Cohort was analyzed. Perinatal information including both maternal and offspring datum was recorded. A refined questionnaire was used to evaluate the frequency and duration of children's PA levels. Blood pressure, echocardiography, and anthropometry assessment were conducted during the follow-up of 7-year-old children.ResultsOverall, high PA level was associated with higher left ventricle posterior wall thickness in diastole (LVPWd, β coefficient: 0.36, 95% CI: 0.12, 0.61), higher left ventricle mass index (LVMI, β = 0.28, 95% CI: 0.07, 0.48), mitral E/a ratio (β = 0.47, 95% CI: 0.22, 0.71) and slower heart rate (β = -0.32, 95% CI: -0.57, -0.07), compared to low PA level. Medium PA level was associated with lower diastolic blood pressure (DBP, β = -0.18, 95% CI: -0.35, -0.01). In subgroup analysis, increased relative wall thickness (RWT) was found in high PA level boys (β = 0.36, 95% CI: 0.05, 0.67), and systolic blood pressure (SBP) showed a significant decrease in high PA level girls (β = -0.42, 95% CI: -0.78, -0.06).ConclusionsThis study suggested non-athlete children having higher PA level were associated with thicker left ventricle (LV) walls and better LV diastolic function, as well as slower heart rate and DBP at the age of 7. Furthermore, disparity in the association between PA level with morphological heart patterns and blood pressure existed in different sex category.

Project description:ObjectiveTo study the cross-sectional and prospective associations between physical activity (PA) of different intensities, body mass index (BMI) and waist circumference (WC) in children and adolescents using isotemporal substitution modelling.MethodsPhysical activity (accelerometry), BMI and WC were assessed in 6- (n = 970), 9- (n = 2,423) and 15-year-olds (n = 1,544) in 2005/2006 and 2011/2012. Participants aged 9 years in 2005/2006 were followed prospectively to 2011/12 (age 15). Associations between PA of different intensities (light, moderate and vigorous), BMI and WC were examined using isotemporal substitution models.ResultsSubstituting 10 min per day of sedentary time with light PA was associated with higher WC (0.17 to 0.29 cm, p ? 0.003)) in all age groups. Substituting 10 min per day of sedentary time with moderate PA was associated with lower WC in 6- and 9-year-olds (-0.32 to -0.47 cm, p ? 0.013)). Substituting 10 min per day of sedentary time with vigorous PA was associated with lower WC in 9- and 15-year-olds (-1.08 to -1.79 cm, p ? 0.015)). Associations were similar with BMI as the outcome. In prospective analyses, substituting sedentary time with light, moderate or vigorous PA at age 9 was not associated with BMI or WC at age 15.ConclusionSubstituting sedentary time with moderate PA appears favourably associated with adiposity in children, whereas vigorous PA may be required in adolescents. Cross-sectional associations were not replicated in prospective analyses.

Project description:To evaluate the relationships between objectively measured physical activity and physical fitness among preschool children.A total of 346 participants (201 boys and 145 girls) aged 3.5-5.5 years (M = 4.5?yr, SD = 0.47) from Shanghai, China, completed physical fitness assessments, including triceps skinfold thickness (TSFT), grip strength, tennis throwing, sit and reach test, standing long jump, balance beam, 10mSRT, and 20mSRT. Physical activity was objectively measured by ActiGraphGT3X+ accelerometer. Multiple linear regression models were used to explore the cross-sectional associations between PA and physical fitness after adjusting for age, gender, BMI, and valid wearing time.Positive associations were observed between stand long jump (p < .01), tennis throwing (p < .01), laps in 20mSRT (p < .01), and MVPA. However, TSFT (p < .05), time in 10mSRT (p < .01), and balance beam (p < .05) were negatively associated with MVPA. Furthermore, positive associations were found between stand long jump (p < .01), tennis throwing (p < .01), and MVPA only in boys. Negative associations were found between time on balance beam (p < .01) and MVPA only in girls.MVPA appears to be an effective and reliable predictor of preschoolers' physical fitness. Boys' body composition, muscular strength, explosive strength, agility, aerobic fitness, girls' agility, aerobic fitness, and balance could improve as MVPA increases.

Project description:BACKGROUND:This relationship between hypertension (HTN) and osteoporosis (OP) is not well documented among the population in China. The study sought to study the relationship between HTN and OP in Chinese postmenopausal women. METHODS:This cross-sectional study involved 1878 Chinese postmenopausal women with an average age of 62.38 years. OP was diagnosed by standardized quantitative ultrasound at the calcaneus and HTN was defined by blood pressure data and/or the use of antihypertensive medication. The relationship for OP and HTN were calculated using univariate and multivariate regression analyses. RESULTS:The prevalence of OP was 28.17% in the postmenopausal women, and there was a significant difference in the prevalence of OP between the two groups according to HTN (P value = 0.003). Univariate analysis demonstrates a positive correlation between HTN and OP. After adjustment for relevant potential confounding factors, multivariate logistic regression analyses detected significant associations between HTN and OP (P value = 0.096). In participants with HTN, the OR for OP was 1.209 (95% CI: 0.967-1.513). CONCLUSION:The prevalence of OP was more frequent in Chinese postmenopausal women with HTN, and HTN was independently and significantly associated with OP.

Project description:ObjectivesPhysical activity is a cornerstone of chronic disease prevention and treatment, yet most US adults do not perform levels recommended for health. The neighborhood-built environment (BE) may support or hinder physical activity levels. This study investigated whether identical twins who reside in more walkable BEs have greater activity levels than twins who reside in less walkable BEs (between-twin analysis), and whether associations remain significant when controlling for genetic and shared environmental factors (within-twin analysis).DesignA cross-sectional study.SettingThe Puget Sound region around Seattle, Washington, USA.ParticipantsThe sample consisted of 112 identical twin pairs who completed an in-person assessment and 2-week at-home measurement protocol using a global positioning system (GPS)monitor and accelerometer.ExposureThe walkability of each participants' place of residence was calculated using three BE dimensions (intersection density, population density and destination accessibility). For each variable, z scores were calculated and summed to produce the final walkability score.OutcomesObjectively measured bouts of walking and moderate-to-vigorous physical activity (MVPA), expressed as minutes per week.ResultsWalkability was associated with walking bouts (but not MVPA) within the neighbourhood, both between (b=0.58, SE=0.13, p<0.001) and within pairs (b=0.61, SE=0.18, p=0.001). For a pair with a 2-unit difference in walkability, the twin in a more walkable neighbourhood is likely to walk approximately 16 min per week more than the co-twin who lives in a less walkable neighbourhood.ConclusionsThis study provides robust evidence of an association between walkability and objective walking bouts. Improvements to the neighbourhood BE could potentially lead to increased activity levels in communities throughout the USA.

Project description:ObjectivesYoung adults' physical activity (PA) is a foundation of creating future healthy lifestyles. The purpose of this study was to explore differences in PA, sedentary behaviour, walkability and health beliefs among young adults with different levels of cardiometabolic risks and the influence of moderate-to-vigorous PA.DesignA cross-sectional study was conducted using a structured questionnaire.ParticipantsTotally, 1149 valid responses were received for a response rate of 86.32%. According to the self-reported worst health condition, participants were categorised into healthy adults, and adults at levels 1 (overweight), 2 (obese), 3 (hypertensive, hyperlipidaemic, and/or hyperglycaemic), and 4 (with a diagnosis of cardiometabolic diseases) of cardiometabolic risks.Primary outcome measuresPA, sedentary time, walkability and health beliefs.ResultsSignificant differences in PA (F=3.78, p<0.01) and sedentary time (F=2.39, p<0.05) among groups with various cardiometabolic risk levels were found. Healthy adults and adults at level 1 risk had significantly higher PA than adults at risk levels 2 and 3. Young adults at risk level 3 were less likely to participate in moderate-to-vigorous PA than were healthy adults (OR=0.64 (95% CI 0.41 to 0.99), p<0.05). Individuals who perceived that there were more recreational facilities (OR=1.27 (1.05 to 1.53), p<0.05), who had higher benefits of exercise (OR=1.73 (1.30 to 2.31), p<0.001), and who had lower barriers to exercise (OR=0.42 (0.32 to 0.55), p<0.001) were more likely to participate in moderate-to-vigorous PA.ConclusionsBeing aware of body weight changes could be a danger sign of a lack of PA. Developing environmental and psychological strategies to promote engaging in PA is necessary to promote the cardiometabolic health of young adults.
