“…A national survey of Chinese children aged 6–17 years ( n = 62, 517) found that adolescents from rural areas spent more time in outdoor activities than their counterparts living in urban areas [ 13 ]. However, the China 2018 Report Card on physical activity for children and youth indicated that only 13.1% students reported being physically active at 60 min daily, whereas 92.9% students reported having 2 h of screen time or more per day [ 14 ]. Despite of the concerning situation, whether and to what extent lack of outdoor activity and excessive screen time are relevant to unhealthy weight gain among rural Chinese children and adolescents remain largely unknown.…”

Background Whether and to what extent outdoor activity and screen time are relevant to adiposity among rural adolescents remain largely unknown as most of relevant evidence was generated from high-income countries and urban areas. This study aimed to investigate associations of outdoor activity and screen time with adiposity among early adolescents living in rural southwest China. Methods In this cross-sectional study, seventh graders (n = 2264) were recruited from 10 middle schools of a rural county. Overweight and obesity was assessed using adolescents’ body mass index and waist circumference. Adolescents’ outdoor activity and screen time were measured using self-reported daily time spending on outdoor activity, watching TV, playing video games, and computers on weekdays and weekends, respectively. Results The prevalence of overweight/obesity and high waist circumferences were 8.0 and 4.9% and were higher among those from one-child families and with parents having high school or higher education and whose fathers were not farmers. Adolescents who did not have ≥1 h outdoor activity on weekdays were more likely to be overweight/obese (OR: 1.86, 95% CI: 1.30, 2.66) and have high waist circumferences (OR: 2.22, 95%CI: 1.39, 3.57). Adolescents who had > 2 h screen time on weekends were more likely to have high waist circumferences (OR: 2.08, 95% CI: 1.14, 3.80). Lack of outdoor activity and excessive screen time also showed synergistic effects on overweight/obesity (OR: 1.93. 95% CI: 1.15, 3.24) and high waist circumferences (OR: 3.02, 95% CI: 1.54, 5.94). Conclusions Lack of outdoor activity and excessive screen time were relevant to adiposity among rural Chinese adolescents even when the obesity prevalence was low. Efforts to promote active lifestyles may help prevent rural adolescents from losing their advantage in the era of the global obesity epidemic.

“…Over the past 20 years, there has been an increasing number of studies, conducted at both the regional and national levels, on Chinese school-aged children's PA 15 , 20, 21, 22, 23, 24, 25. An early landmark study of 1997 national survey data showed that 72% of Chinese youth engaged in in-school MVPA, with as few as 8% reporting MVPA outside the school setting 15 .…”

HighlightsThe proportion of school-aged children and adolescents in China who engage in recommended levels of physical activity (PA), in or outside of school time, has been declining for decades.Current PA promotion policies for Chinese schools are primarily “stand-alone” approaches and their efficacy appears limited.Re-evaluating the problem from a comprehensive social-ecological perspective within a public health model offers greater potential for developing effective and culturally appropriate interventions to increase PA among Chinese youth.If the goals of Healthy China 2030, including the prevention of the early onset of chronic diseases among Chinese children and adolescents, are to be met by reversing the trend of declining PA, careful consideration of this new paradigm is imperative.

“…At the time of this study, Chinees schools instituted twice a day outdoor running activity for attendees. Note that such policies do not appear to be uniform across China [ 41 , 42 ]. Offspring may have reported this activity under activities in the school domain or reported it under the leisure time activity domain.…”

“…Key strengths of the study include the extensive effort to test the performance and feasibility of instrument and self-report measurement of PA in mothers and offspring from two distinct settings in China. Such detailed analyses of urban and rural differences and inclusion of cross-generational comparisons are important because of rapid increases in sedentary behavior, obesity, diabetes, and urban–rural disparities in China [ 41 ]. The results reported here and in related papers concerning UVR exposure, diet and other variables [ 29 , 30 , 31 ] also provide valuable guidance both for a potential follow up to the 1993–1995 Community Intervention Program (CIP) and for PA measurement in other cohort studies in China.…”

Objectives: This paper describes the development of a physical activity questionnaire (PAQ) designed for Chinese adolescents and their mothers in urban and rural settings, and reports on results of the PAQ, pedometry, and hand grip dynamometry from the Chinese Children and Families Cohort Study pilot investigation (CFCS). Methods: As part of a pilot investigation to evaluate the feasibility to follow-up and obtain detailed nutrition, dietary, physical activity, and ultraviolet radiation (UVR) data from CFCS participants, data were collected in 2013 for 93 adolescent/mother pairs from a rural (n = 41) and an urban site (n = 52) in two provinces. Respondents were asked to wear a pedometer for seven days (Omron HJ-151), use a Takei Digital Grip Strength Dynamometer on (each hand; three trials; two separate days), and complete a 39 item, eight domain PAQ covering the past year. Self-reported physical activity (PA) was linked to metabolic equivalent of task (MET) scores in kcal/kg/hr and used to calculate METs for different domains of PA and intensity categories. Results: Compliance was high (95%) in this measurement protocol administered by health staff during a series of data collection efforts at home and local clinics or health centers. Step counts were highly variable, averaging between 5000 and 10000 per day with somewhat higher step counts in rural adolescent boys. Maximum grip strength (Kgs) was greater in children (Mean = 36.5, SE = 0.8) than mothers (Mean = 28.8, SE = 0.8) and similar in the urban (Mean = 29.6, SE = 0.6) compared to the rural (Mean = 29.6, SE = 0.5) communities overall. Grip strength, step counts, and measures of time spent in different activities or activity intensities were uncorrelated. Conclusion: Device and question-based measurement of PA and strength were readily accepted in these Chinese urban and rural populations. The PAQ on physical activity in the past year produced some plausible population averages, but individual responses suggested recall challenges. If data about specific activities are required, future studies should explore use of standardized survey questions concerning such fewer specific activities or instruments examining shorter time periods such as one, three, or seven day recalls.
