Describing physical activity in public open spaces in Brazil: Active City, Healthy City Program

This study aimed to describe the physical activity (PA) in public open spaces (POS) in a medium-sized city in Brazil. The System for Observing Play and Recreation in Communities (SOPARC) was applied to evaluate a representative sample of users in 10 POS which received actions from the Active City, Healthy City Program. The places were evaluated four days a week (Tuesday, Wednesday, Saturday, and Sunday) at four times (8 am, 10 am, 2 pm, and 4 pm). The proportion of users by gender, age group, skin color, and PA level was compared between the POS using the chi-square test for heterogeneity in the STATA software (p<0.05). As main results, 32,768 scans were performed in 64 target areas and identified 8,634 individuals. The highest proportion of people were males (58%), adults (38%), with white skin color (97%), and in light or moderate PA (76%). Except for skin color, there was a significant difference in the proportion of all other variables between the POS (p < 0.05). In conclusion, the POS was more commonly used by men, adults, and people of white skin color for light and moderate PA. Based on the results, program managers could reallocate resources to increase utilization and PA at each place.
