Over half (56%) of students had at least five repeated annual observations (range 1 to 11).
Weight category was defined according to Centers for Disease Control growth chart-derived norms for sex and age in months, and used to compute the BMI percentile for each child. Weight categories categorized as underweight: <the 5th percentile; healthy weight: ≥5th to <85th percentile; overweight: ≥85th to <95th percentile; obesity class I: ≥95th percentile-120% of the 95th percentile; obesity class II: ≥120% of the 95th percentile; and obesity class III: ≥140% of the 95th percentile.
