Relationship between physical activity and neighborhood environment in preschool children during COVID-19.-A cross-sectional study using 24-hour activity records.

Maintaining physical activity and the development of physical and cognitive functions are essential especially in vulnerable populations such as children. Considering the substantial impact of the COVID-19 epidemic on preschool children and the lack of research focusing on this age group, this study examined the duration of physical activity among preschool-aged children on weekend days and its relationship with the environment. This study was conducted between October and November 2021, with the cooperation of 357 parents of preschoolers attending kindergartens, nurseries, and childcare centers. Physical activity was assessed using a 24h physical activity record. A questionnaire was used to collect basic data on the neighborhood environment. Stepwise multiple regression analysis was used to analyze the relationship between the five physical activity measures (sedentary time, screen time, indoor playing time, outdoor playing time, and going out time) and the questionnaire data. Our findings revealed a relationship between physical activity and the neighborhood environment; however, the R2 values were low. Despite low prediction accuracy, the results of this study were similar to those of previous studies, indicating a positive correlation of physical activity with the absence of undulating roads, a crime-free environment, and safety around the home. Overall, these findings emphasize the need for providing children with opportunities for outdoor physical activity and play in the context of the COVID-19 recovery phase for adherence to the relevant guidelines.
