Background Despite the rising childhood obesity rates, few studies have examined the association between access to recreational parks and facilities and obesity. Methods A cross-sectional study was performed among 42 278 US children who participated in the 2007 National Survey of Children's Health. Access to parks and recreational facilities was self-reported by parents, and body mass index was calculated from parents'self-report of the child's height and weight. Logistic regression was used to obtain ORs and 95% Cls. Since obesity was not a rare occurrence, an OR correction method was used to provide a more reliable estimate of the prevalence ratio (PR). Results Children with access to parks and facilities had decreased prevalence of obesity as compared to children without access (PR=0.79,95% CI 0.69 to 0.91). After adjustment for covariates, the magnitude of the association remained unchanged ; however, results were no longer statistically significant (PR=0.77,95% CI 0.55 to 1.07). Race/ethnicity was an effect modifier of the access-obesity relationship (p
