Objective To investigate the current situation of one-day physical activities of children in the kindergartens in each county and district of Chongqing, and to compare the activity types and time arrangements of preschool children at different ages in the kindergartens of different counties and districts in Chongqing, so as to provide basis for guiding preschool children to carry out scientific activities. Methods In January 2022, 4 714 kindergarten classes (including large, middle, small and mixed-age classes) from 1 798 kindergartens (including first-level, second-level, third-level, and unrated kindergartens) in 40 counties/districts in Chongqing were randomly selected in this study by stratified cluster sampling. Questionnaire survey was conducted to investigate the physical activities arrangement of each kindergarten class from Monday to Friday, including static activities time (electronic screen time and non-screen time), low-intensity physical activity time, moderate- to high-intensity physical activity time and total physical activity time. The rates of standard-obtained time for various activities were compared. Results Electronic screen time, non-electronic screen time, time for low-intensity physical activity, moderate- to high-intensity physical activity, and total exercise time was 29.6min, 93.9min, 19.0min, 123.3min and 142.3min, respectively. The compliance rates of time for electronic screen, moderate- to high-intensity physical activity and total physical activity were 71.8%, 95.7%and 57.9%, respectively, which were significantly different among the first, the second, the third level and unrated kindergartens(χ2=66.877, 9.854, 10.083, P<0.05), and among the large, the middle, the small and mixed-age classes(χ2=208.440, 53.749, 152.336, P<0.001). Conclusions The time and types of one-day physical activity are insufficient and imbalanced among kindergartens with different levels and grades from Chongqing. It is necessary to adjust the arrangement of physical activity in kindergartens.
