Note. Model 1 estimated the effect of the total number of laws p0 on BMI z-score; Model 2 estimated the effects of p1, p2, p3, and p4 on BMI z-score; Model 3 estimated the effects of p1, p2, p3, and p4 on BMI z-score, however, only legislation that specifically targeted youth were included; Model 4 estimated the effects of p1, p2, p3, and p4 on BMI z-score, however, only legislation that was implemented before 2015 was included.

Note. Estimates and corresponding standard errors and p-values of exploratory linear regression models with proportion overweight/obesity as dependent variable.
