low-fat milk had a noticeably stronger tendency to pack on the pounds

To evaluate relationships between type of milk consumed and weight status
among preschool children.
Longitudinal cohort study.
The Early Childhood Longitudinal Study, Birth Cohort, a representative sample
of US children.
10 700 US children examined at age 2 and 4 years.
Body mass index (BMI) z score and overweight/obese status as a function
of milk type intake.
The majority of children drank whole or 2% milk (87% at 2 years, 79.3% at
4 years). Across racial/ethnic and socio-economic status subgroups, 1%/skim
milk drinkers had higher BMI z scores than 2%/whole milk drinkers. In multivariable
analyses, increasing fat content in the type of milk consumed was inversely
associated with BMI z score (p<0.0001). Compared to those drinking 2%/whole
milk, 2- and 4-year-old children drinking 1%/skim milk had an increased
adjusted odds of being overweight (age 2 OR 1.64, p<0.0001; age 4 OR
1.63, p<0.0001) or obese (age 2 OR 1.57, p<0.01; age 4 OR 1.64, p<0.0001).
In longitudinal analysis, children drinking 1%/skim milk at both 2 and 4
years were more likely to become overweight/obese between these time points
(adjusted OR 1.57, p<0.05).
Consumption of 1%/skim milk is more common among overweight/obese preschoolers,
potentially reflecting the choice of parents to give overweight/obese children
low-fat milk to drink. Nevertheless, 1%/skim milk does not appear to restrain
body weight gain between 2 and 4 years of age in this age range, emphasising
a need for weight-targeted recommendations with a stronger evidence base.
