RESUMEN
BACKGROUND: This study aimed to evaluate parental perception of neighbourhood environments and safety in association with children's physical activity among primary school children in Klang, Selangor, Malaysia. METHODS: A total of 250 children (9-12 years of age) and their parents participated in this cross-sectional study. Physical Activity Questionnaire for Older Children and Neighbourhood Environmental Walkability Scale as well as questions on constrained behaviours (avoidance and defensive behaviours) were used to assess the children's physical activity and parental perception of neighbourhood environment and safety, respectively. RESULTS: More than one-third (36.0%) of the children were physically inactive compared with only a small percentage (4.8%) who were physically active, with boys achieving higher physical activity levels than girls (t = 2.564, P = 0.011). For the environmental scale, parents' perception of land-use mix (access) (r = 0.173, P = 0.006), traffic hazards (r = -0.152, P = 0.016) and defensive behaviour (r = -0.024, P = 0.143) correlated significantly with children's physical activity. In multiple linear regression analysis, child's gender (ß = -0.226; P = 0.003), parent's education (ß = 0.140; P = 0.001), household income (ß = 0.151; P = 0.024), land-use mix (access) (ß = 0.134; P = 0.011) and defensive behaviour (ß = -0.017; P = 0.038) were significantly associated with physical activity in children (R = 0.349, F = 6.760; P < 0.001), contributing 12.2% of the variances in physical activity of the children. CONCLUSION: Results highlight the links between parental perception of neighbourhood environments, safety and constrained behaviours with their children's participation in active play. Interventions aimed to increase actual and perceived safety and reduce perceptions of risk by parents in safe neighbourhoods can be targeted to increase children's physical activity in their local neighbourhoods.
