Obesity is less common in infants who sleep more and wake up less often – Consumer Health News

MONDAY, October 25, 2021 (HealthDay News) – According to a study published online in SLEEP on October 22, an increase in the length of nighttime sleep and a decrease in waking attacks are associated with a lower chance of obesity in infants 1 to 6 months of age .

Xiaoyu Li of Harvard TH Chan School of Public Health in Boston and colleagues studied 298 full term infants to examine the longitudinal association of changes in objectively assessed sleep-wake patterns with changes in growth at 1 to 6 months of age.

The mean birth weight of the cohort was 3.4 kg. The researchers found that every one hour increase in nighttime sleep between months 1 and 6 in multivariably fitted models was associated with a significant decrease in the probability of obesity from 1 to 6 months (odds ratio 0.74). A significant reduction in the likelihood of obesity was also observed for each unit reduction in the number of wake-ups (odds ratio, 0.84). No association between changes in wakefulness after falling asleep and the likelihood of obesity was observed.

“Our results showed that longer night sleep and reduced fragmentation of night sleep were associated with a lower likelihood of obesity from 1 to 6 months,” the authors write. “Once obesity is present, it is difficult to treat because entrenched behaviors and metabolic forces counteract weight loss, so it is important that parents and carers start preventative measures as early as possible.”
