Parental perceptions of neighborhood safety and preschool children's outdoor play: An exploration of sex and safety type differences.

Despite the growing evidence on the influence of neighborhood safety on physical activity, few studies have specifically focused on preschool-aged children and differentiated the various domains of neighborhood safety. This study investigates the relationship between parental perceptions of neighborhood safety and preschool children's time spent outdoors and explores potential sex differences in this relationship. This study analyzed nationally representative data from 1656 Korean children (848 boys and 808 girls) aged 3, 5, 6 years collected over the course of three waves of the Panel Study on Korean Children (PSKC). Outdoor playtime was measured by maternal reports of the time their children spent playing outdoors on a typical weekday. Parental perceptions of neighborhood safety were assessed using two items that inquired about neighborhood safety in terms of crime and accidents, respectively. Fixed effects estimates revealed that parental perceptions of social safety were associated with an increase in children's outdoor physical activity (b = 3.778, p < 0.05), whereas perceptions of physical safety were not. Sex-stratified models showed that the association between parental perceptions of social safety and children's outdoor play was driven largely by boys (b = 8.498, p < 0.001), with no association observed for girls. The findings of this study underscore the importance of addressing the social safety of neighborhood environments to promote outdoor play in preschool children. Moreover, sex differences should be considered when developing interventions aimed at increasing physical activity among young children.
