Recent Trends in Physical Activity among Chinese Children Based on Their Demographic and Social Characteristics.

Abstract

Aimed to explore the trends in physical activity among Chinese children, data of 4,341 children aged 6-17 years who participated in at least one round of China Health and Nutrition Survey from 2004 to 2015 were analyzed. Repeated measures mixed models were applied to test the trends in physical activity, which were further analyzed after applying stratification on gender, age, urbanization level, residential area and region. The volume of total physical activity in Chinese children aged 6-17 years showed a downward trend from 2004 to 2015, especially among children residing in medium and high urbanization communities, the south and urban areas of China, so that more efforts need to be put to promote their physical activity.
