Differences in Lifestyle Behaviours of Students between Inner Urban and Peri-urban High Schools: A Cross-Sectional Study in Chongqing, China.

Background: Lifestyle behaviours of students from schools in different socioeconomic areas may be different. Few studies have investigated such topics in China. This study aimed to explore the differences in lifestyle behaviours between inner urban high school students (IUHSSs) and peri-urban high school students (PUHSSs).

Methods: A cross-sectional survey based on a self-report questionnaire was administered among 1560 high school students (726 from inner urban high schools and 834 from peri-urban high schools) in Chongqing, China. Physical activity, sleep time, screen time and dietary behaviours were assessed according to a series of recommendations of Chinese guidelines.

Results: No significant difference was found in meeting the recommendation for daily physical activity between IUHSSs and PUHSSs (7.6% vs. 6.8%, > 0.05). PUHSSs were more likely to meet the recommendations of weekdays' sleep time (14.9% vs. 5.4%, < 0.001), weekdays' and weekends' screen time (85.4% vs. 76.7%, < 0.001; 21.1% vs. 14.3%, < 0.001), and had higher proportion of high-score group of dietary behaviours (58.6% vs. 36.4%, < 0.001) than those of IUHSSs. IUHSSs were more likely to meet the recommendation of weekends' sleep time (75.6% vs. 67.9%, < 0.001) than that of PUHSSs.

Conclusions: A low proportion met the recommendations of physical activity, weekdays' sleep time and weekends' screen time among high school students in Chongqing, China. Lifestyle behaviours may differ between inner urban and peri-urban high school students. Additional support or targeted health education should be provided by high schools to improve the lifestyle behaviours of students, especially in inner urban districts.
