Abstract
OBJECTIVE: We aimed to explore the effect of individualized medical nutrition guidance on pregnancy outcomes among older pregnant women. METHODS: This was a prospective study using a randomized controlled trial design. We selected 820 older pregnant women and randomly divided them into a study group and control group (410 women each). The control group was given routine health education and nutrition guidance; the study group was provided individualized medical nutrition guidance. Gestational diabetes mellitus, hypertensive disorders of pregnancy, vaginal delivery rate, postpartum hemorrhage rate, gestational body weight, neonatal birth weight, and neonate transfer to the neonatal intensive care unit (NICU) were compared between the groups. RESULTS: The incidence of gestational diabetes in the study group was significantly lower and the rate of vaginal delivery was significantly higher than those in the control group. The incidence of macrosomia, rate of neonatal transfer to the NICU, and rate of neonatal hyperbilirubinemia were significantly lower in the study group than those in the control group. CONCLUSIONS: Individualized nutritional intervention for older pregnant women can effectively reduce the incidence of complications during pregnancy and childbirth and improve maternal and child outcomes.
