¹Values represent mean (95% CI) changes. Quartiles of full-fat dairy intakes are sex- and baseline-BMI–specific. Relations between total dairy intakes and changes in BMI were examined by ANCOVA (PROC GLM in SAS). P-trend was determined by treating quartiles of dairy intake as a continuous variable in multivariable models. Model 1 (simple): age 10 y, sex, height at 10 y, total dairy at 13 y (categorical), and adiposity at 10 y (continuous); model 2 (demographic characteristics): model 1 plus maternal education and overweight status, physical activity at 13 y, pubertal stage at 13 y, and dieting at 13 y; model 3 (diet): model 2 plus age-10-y intakes of fruit juice, fruit and vegetables, total fat, total protein, sugar-sweetened beverages, fiber, and cereal; model 4 (reporting errors): model 3 additionally adjusted for dietary reporting errors at 13 y; model 5 (energy adjusted): model 4 plus adjustment for total dairy intakes. *P < 0.05 and ^†P = 0.05 compared with Q1 full-fat dairy intakes. Q, quartile.

²Values represent mean ± SD (5th–95th percentile) full-fat dairy intakes at age 10 y.
