Sleep-wake patterns in newborns are associated with infant rapid weight gain and incident adiposity in toddlerhood

Infants napping 5 or more times per day at 1 month of age had 89% lower odds of experiencing rapid weight gain by 6 months compared to infants napping less than 5 times per day (OR = 0.11, 95% CI: 0.0

Effect: improvement; OR = 0.11; CI: 95% CI: 0.02, 0.63

Each 1-hour increase in the difference between nocturnal and diurnal sleep (in favor of proportionately more nocturnal sleep) at 1 month of age was associated with 51% greater odds of incident overwei

Effect: decline; OR = 1.51; CI: 95%CI: 1.13, 2.03

After full adjustment, each 1-hour increase in nocturnal total sleep time at 1 month was not significantly associated with incident overweight at 36 months (OR: 1.41, 95% CI: 0.99, 2.03), although the

Effect: null; OR: 1.41; CI: 95%CI: 0.99, 2.03

Rapid weight gain at 6 months of life was associated with 2.35 times the odds of overweight at 36 months (OR = 2.35, 95% CI: 1.02, 5.42, P = .04) in this high-risk cohort.
