Physical Activity, Screen-Based Sedentary Behavior and Physical Fitness in Chinese Adolescents: A Cross-Sectional Study

Abstract

Purpose: The aim of this study is to explore the relationship between screen-based sedentary behavior, physical activity and physical fitness among Chinese adolescents.Methods: This study randomly selected adolescents from 10 administrative districts in Shandong, China. The data gathering tools for demographic and other characteristics (gender, age, body mass index and socioeconomic status), PA (PAQ-A) and screen-based sedentary behavior (YRBSS) and physical fitness (NSPFH 2014) were utilized in this study. Statistical analysis was performed by T-test, chi-square test and multiple linear regression.Results: 10,002 adolescents (14.39 years ± 1.79) participated in the study. The results demonstrated that BMI and high TV viewing time had a significant negative correlation with physical fitness, but there was no association between the amount of time spent playing computer/video games and physical fitness among adolescents. High SES and physical activity in leisure time five or more times per week were significantly associated with most dimensions of physical fitness.Conclusions: the results suggest that we not only need to focus on adolescent risk behavior associated with low socioeconomic status and obesity, but also enforce physical activity and reduce sedentary television-watching behavior, which will be crucial pathways and strategies to improve the physical fitness of Chinese adolescents.

Influence of Sport Practice and Body Weight on Physical Fitness in Schoolchildren Living in the Campania Region

“…The PF levels found in this pilot study enforce the known relationship among regional socioeconomic level, PA, and PF [ 3 , 4 , 48 ].…”

“…Campania is one of the Italian regions with the lowest per capita income; in fact, according to the most recent survey by the Istituto Nazionale di Statistica, in Campania the share of households in relative poverty is higher (24.9%) compared to the national share (11.8%) [ 46 ]. Moreover, the Campania region provides the most limited public spaces available to exercise safely in free time and the highest number of schools without a proper gym for students (>70%) [ 47 ]; on the other hand, it is acknowledged that the more developed and higher-income districts may provide more educational resources and public spaces for children so they have more opportunities to participate in PA [ 48 ].…”

A Dataset on the Status Quo of Health and Health-Related Behaviors of Chinese Youth: A Longitudinal Large-Scale Survey in the Secondary School Students of Shandong Province

“…Physical activity was assessed using the Physical Activity Questionnaire for Adolescents (PAQ-A), a revised version of the Physical Activity Questionnaire for Older Children (PAQ-C) [11,12] . This questionnaire mainly asks adolescents what they did in most of their leisure time in the past 7 days.…”

“…The intensity of physical activity (PA) was scored on a 5-point scale (1-5), with a higher score indicating a higher intensity. Scores in range of 1-1.9 are categorized into low PA level, and 2-5 are categorized into high PA level [12].…”

“…This running test is to evaluate cardiorespiratory endurance. All the girls were subjected to run 800 meters and the boys were subjected to run 1,000 meters [12] .Time to complete the whole course was recorded in minutes and seconds.…”
