5. Study Description

Brief Summary
Gestational diabetes mellitus (GDM) affects 10 % of women who receive prenatal care at Instituto Nacional de Perinatología (Mexico, City). Currently, there is clear evidence on the utility of self- monitoring of capillary glucose (SMGC) to evaluate the efficacy of medical-nutrition therapy on glycemic control. However, the reports regarding the best pattern of SMGC in terms of frequency and number of determinations per day are limited. The objective of this study is to evaluate the efficacy of two SMGC schemes for monitoring glycemic control in Mexican women with GDM.
Detailed Description
Currently, the evidence from randomized clinical trials about the most appropriate scheme of SMGC for monitoring the glycemic control among women with GDM is limited. This study was designed to evaluate the efficacy of two different schemes of SMGC in GDM Mexican population, it is an open-label randomized clinical trial including 2 groups: group 1 (SMGC 4 times/day) measured in fasting and 1 hour postprandial of breakfast, lunch and dinner; group 2 (SMGC 2 times/day), measured preprandial and 1 hour postprandial, of breakfast, lunch or dinner, alternating the meal each day, from GDM diagnosis until the resolution of pregnancy. Additionally, determinations of insulin, lipids and glycosylated hemoglobin (HbA1c) will be determinate at enrollment, and between the 30-32 and 36-38 of gestation week. The primary outcome: To compare the proportion of women who achieve glycemic control using SMGC 4 times/day versus SMGC 2 times/day. Secondary outcome: To compare the risk of new-born large for gestational age, gestational hypertension, preeclampsia, preterm birth, cesarean section, new-born weight, neonatal hypoglycemia, neonatal hyperbilirubinemia and entry to neonatal intensive care between groups. An analysis for intention of treatment will be made according to the recommendations of the CONSORT guidelines.
