The role of a personalized dietary intervention in managing gestational weight gain: a prospective, controlled study in a low-risk antenatal population.

Purpose: To compare the efficacy of a personal dietary intervention on gestational weight gain control with a general intervention promoting healthy eating.

Methods: Prospective, controlled study including 154 low-risk pregnant women randomly allocated to two groups: 77 receiving a personalized diet plan and a close follow-up by a dietician (intervention group), 77 receiving standard dietary care by means of a brochure on healthy eating during pregnancy (control group). Pre-pregnancy weight, gestational age, height, weight and BMI at baseline, weight at term, gestational age at delivery and newborn weight were recorded for all participants.
