Lifestyle intervention on diet and exercise reduced excessive gestational weight gain in pregnant women under a randomized controlled trial

摘要

Excessive gestational weight gain (EGWG) during pregnancy increases the risk of fetal macrosomia, maternal overweight status, and postpartum weight retention. Its prevention potentially improves maternal and neonatal outcomes. Important contributing factors to EGWG include excessive caloric intake and inadequate levels of physical activity. A number of studies have examined the effects of lifestyle intervention (dietary intervention with or without increased physical activity) on the prevalence of EGWG, but the results have been mixed.
