Spatial Distribution and Related Factors of Physical Activity, Screen Time and Sleep Time Compliance Rates of Chinese Children from 3 to 6 Years Old

Objective: To understand the compliance status of physical activity, screen time and sleep time behaviors of Chinese children from 3 to 6 years old, then to explore the spatial distribution characteristics and related factors of the compliance status in different regions of China. Methods: Based on the preschool children's data of the “National Fitness Status Survey in 2020”, the physical activity, sleep time and screen time behaviors and related factors of 10 967 children in 31 provinces were analyzed. The local indicators of spatial autocorrelation(LISA) was used to analyze the spatial aggregation characteristics of each index. Results:1) According to the Guidelines on Physical Activity, Sedentary Behaviour and Sleep for Children under 5 Years of Age published by WHO, the compliance rates of moderate-vigorous physical activity(MVPA), screen time and sleep time were respectively 62.3%,52.8% and 53.8% in Chinese children from 3 to 6 years old. Among them, the children who met all of the three types behaviors was 16.4%, and the children who didn't meet any of the three standards was 7.9%. 2) From the results of LISA, the high compliance areas of MVPA and screen time was the north of China, while the low compliance areas were mostly in the south, and the high compliance areas of sleep was the southwest. 3) The factors related to the spatial distribution characteristics of MVPA compliance rate were average temperature, number of household sporting goods, parents' accompanying exercise and annual household income(P<0.05); the factors related to the spatial distribution of screen time compliance rate were community service of sports, average temperature and annual household income(P<0.05); factors related to the distribution characteristics of sleep time compliance rate were average temperature and parents' accompanying exercise(P<0.05). Conclusions: The physical activity, screen time and sleep time behaviors of preschool children in China have a certain difference and concentration characteristics in the spatial distribution.The factors related to the spatial distribution of the compliance rate of the three types behaviors are mainly include economy, natural environment and sports facilities. In addition, family sports support is also the important factor for children's health behavior. In order to promote the development of children's healthy behaviors, different regions should take ecological measures from macro to micro levels according to the characteristics of children's behaviors
