Conditions
Summary
Gestational diabetes mellitus (GDM) is one of the most common clinical conditions in pregnancy, with an increasing incidence due to the rise in overweight women and the postponement of motherhood. It is associated with perinatal complications and an increased risk of developing prediabetes and type 2 diabetes after delivery. Therefore, it is recommended that a 75g oral glucose tolerance test (OGTT-75g) be performed between 6 and 12 weeks postpartum. Despite its relevance, the rate of adherence to the test is low. Recent studies also indicate that measuring blood glucose one hour after the overload may be more sensitive than the traditional two-hour measurement in the early detection of dysglycemia. This study aims to evaluate strategies for qualifying the screening of metabolic changes in the postpartum period among women with GDM. The objectives are: (1) to analyze the impact of sending reminders via WhatsApp on the attendance rate for the 75g OGTT; and (2) to compare the frequency of prediabetes and diabetes diagnoses using two different diagnostic strategies applied to the same test-the traditional (fasting and 2-hour blood glucose) and the alternative (fasting and 1-hour blood glucose).
