Adherence to a lifestyle programme in overweight/obese pregnant women and effect on gestational diabetes mellitus: a randomized controlled trial.

ABSTRACT: This study aims to determine whether the prescription of a detailed lifestyle programme in overweight/obese pregnant women influences the occurrence of gestational diabetes (GDM), and if this kind of prescription increases the adherence to a healthier lifestyle in comparison to standard care. The study was designed as a randomized controlled trial, with open allocation, enrolling women at 9-12?weeks of pregnancy with a BMI???25?kg/m2 . The women assigned to the Intervention group (I?=?96) received a hypocaloric, low-glycaemic, low-saturated fat diet and physical activity recommendations. Those assigned to the Standard Care group (SC?=?95) received lifestyle advices regarding healthy nutrition and exercise. Follow-up was planned at the 16th , 20th , 28th and 36th weeks. A total of 131 women completed the study (I?=?69, SC?=?62). The diet adherence was higher in the I (57.9%) than in the SC (38.7%) group. GDM occurred less frequently in the I (18.8%) than in the SC (37.1%, P?=?0.019) group. The adherent women from either groups showed a lower GDM rate (12.5% vs. 41.8%, P ?4000?g were significantly lower in I group. The incidence of small for gestational age babies was not different. These findings demonstrate that the adherence to a personalized, hypocaloric, low-glycaemic, low-saturated fat diet started early in pregnancy prevents GDM occurrence, in women with BMI???25?kg/m2 .
