  • The odds in adjusted models of overweight or obesity among drinkers of 1%/skim milk compared to 2%/whole milk are shown.

  • *Additional information regarding juice, SSB and number of glasses of milk consumed daily was not available at 2 years old.

  • BMI, body mass index; SES, socio-economic status; SSB, sugar-sweetened beverages.
