  • Model 1 includes adjustments for sex, age quartile, month, ethnicity, social position, anthropometric observer, height, and random effect for school. Model 2 is the same as model 1 plus fat mass index. Model 3 is the same as model 1 plus fat-free mass index. Model 4 is the same as model 1 plus fat mass index and fat-free mass index. Insulin and insulin resistance data are missing for 76 children.
