*
indicates statistical significance at the p≤0.05 level for the continuous score outcome
1
Models adjust for child sex, age in days and race/ethnicity; maternal college graduate (yes/no); and household income (>/≤ 70k)
2
Higher sleep scores indicate more often meeting the recommended sleep for age, i.e., children with higher sleep scores had more adequate sleep duration over childhood.
3
Youth Healthy Eating Index (YHEI) score is not adjusted for other mid-childhood dietary factors.
