Aims: This study evaluates the adherence to postpartum type 2 diabetes mellitus (T2DM) screening in women with previous gestational diabetes (GDM) and identifies elements associated with poor attendance.
Methods: We retrospectively collected data from 650 consecutive women with GDM between 2016 and 2018, who should had 75 g-OGTT, 4-12 weeks after delivery. Impaired glucose regulation (IGR) was defined according with ADA criteria.
Results: Only 41% of women had postpartum OGTT. Of these, 1.9% received T2DM diagnosis, with IGR prevalence of 18%. After introducing a recommendation letter, adherence to screening increased (47% in 2017 and 43% in 2018 vs. 32% in 2016). Screening procedure was less common in women with: no-family history of T2DM (38% vs. 46%; p < 0.05), age <35 (33% vs. 47%; p < 0.01), lower level of education (32% no-high-school-diploma vs. 35% high-school-diploma vs. 49% university-degree; p < 0.01) and unstable employment (35% vs. 44%; p < 0.05). At multivariate logistic regression analysis, age <35 years (OR 1.61; 95%CI: 1.14-2.28) and lowest educational level (OR 1.64; 95% CI: 1.13-2.37, compared to University degree) were independently associated with non-adherence.
Conclusion: Only 41% of women had postpartum T2DM screening. Women with lower attendance are those with age <35 years or low educational level. Further strategies are needed to implement postpartum test.
