Loy SL, Cheung YB, Cai S, et al. - Because maternal metabolic disturbance resulting from inappropriate meal timing or sleep deprivation may disrupt circadian rhythm, potentially inducing complications of pregnancy, researchers explored the connections of maternal night-time eating and sleep duration during pregnancy with gestation length and preterm birth. Six hundred seventy-three pregnant women from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort were analyzed. Overall, 15.6% of women had night-eating, 12.3% had short sleep, and 6.8% had preterm delivery. Investigators found that women with higher energy consumption at night during pregnancy than during the day had shorter gestation and a higher probability of preterm delivery. Eating time misalignment with day-night cycles can contribute to preterm birth. This indicates a potential intervention target to lessen the risk of preterm birth. Nightly sleep deprivation observations regarding gestation length and PTB warrant further confirmation.
