Abstract
BackgroundWe examined the correlations between living arrangement and the physical activity (PA) levels of youth aged 9–19 years while accounting for demographic factors such as age, sex, and socioeconomic status in Shanghai, China.MethodsCross-sectional analyses of data from the 2014 Physical Activity and Fitness in Shanghai China—The Youth Study was conducted. Participants were 33,213 primary (9–11-year-olds; n = 13,237), junior middle (12–14-year-olds; n = 11,157), and junior high school students (15–19-year-olds; n = 8819). Youth (boys = 49%) and their guardians were randomly sampled from 17 districts in Shanghai, China. Youths’ moderate-to-vigorous PA (MVPA) levels, information about living arrangement, and guardians’ sociodemographic factors were collected via questionnaires.ResultsOnly 17.8% of school-aged youths in Shanghai met MVPA recommendations, with significantly more boys (20.6%) meeting recommendations than girls (p < .001). Youths living in rural areas showed an overall significantly higher percentage of meeting MVPA recommendations (20.3%) than those living in urban areas (p < .001). Youths who lived with single parents showed an overall significantly lower percentage of meeting MVPA recommendations (15.3%) than those living with their grandparent(s) or with both parents (p < .001). A logistic regression analysis revealed that, among 9–11-year-olds, children who live with their grandparent(s) were less likely to meet MVPA recommendations than those who lived with both parents (boys: adjusted odds ratio (aOR) = 0.72, 95% confidence interval (CI) = 0.61–0.84; girls: aOR = 0.84, 95%CI = 0.72–0.98).ConclusionsType of living arrangement was associated with the PA of youth in Shanghai, with no significant gender difference. Youth aged 9–19 years who lived with single parents had the lowest percentage of meeting MVPA recommendations. The probability of achieving 60 min/day MVPA recommendations was significantly lower among 9–11-year-old children living with their grandparent(s) than children living with both parents; however, no such difference was observed among adolescents. Our findings suggest that living arrangement may be an important consideration for promotion of PA among youth in China.

Sample characteristics Of the total of 38,988 school children who participated in the survey portion of the PAFCTYS, our analyses included valid data obtained from 33,213 children (16,310 boys and 16,903 girls), with 13,237 (29.4%) in Grades 4–6(9–11years-old), 11,157 (34.7%) in Grades 7–9(12–14-yearsold), and 8819 (35.9%) in Grades 10–12(15-to-19yearsold)
Youth living in rural areas had a significantly higher percentage of meeting moderate-to-vigorous PA (MVPA) recommendations than those living in urban areas
Summary
We examined the correlations between living arrangement and the physical activity (PA) levels of youth aged 9–19 years while accounting for demographic factors such as age, sex, and socioeconomic status in Shanghai, China. The World Health Organization (WHO) issued a set of PA guidelines for youths [3]. These guidelines recommended that youths engage in at least 60 min of daily moderate-to-vigorous PA (MVPA). Past studies have shown problematic levels of compliance to PA recommendations. Approximately 80% of adolescents (13–15-year-olds) do not adhere to these recommendations [4,5,6]. In China, only 30% of youths (9–17year-olds) met the MVPA recommendations [7]
