Referent: States with mean rating = 0 for elementary school laws in 2003 and middle school laws in 2006.
Difference between mean rating for state elementary school laws in 2003 and middle school laws in 2006. No change–weak: Equal mean rating (1–2). No change–strong: Equal mean rating (>2). New laws–weak: Mean higher for 2006 middle school laws (1–2). New laws–strong: Mean higher for 2006 middle school laws (>2). Weaker: Mean lower for 2006 middle school laws.
Absolute difference in average within-student change in BMI or probability of overweight/obesity, based on fixed-effect model, adjusted for locale and SES.
