The effect of distance on the adherence to postpartum follow-up in women with gestational diabetes

Despite the increasing prevalence of gestational diabetes mellitus and well-known long-term metabolic consequences, a low rate of postpartum screening in this population is reported. Few studies focused on environmental factors of attending and performing blood glucose screening tests in women with gestational diabetes. This work aimed to assess the proportion of uptake of postpartum follow-up after the first recall and to study the adherence-related factors in women with gestational diabetes. All women with gestational diabetes were recalled for postpartum screening in a tertiary care center as the center of the cohort study in 2016. The postal addresses were geocoded, and precise spatial (x, y) was provided for each mother’s home location. SPSS and GIS were used for data analysis. The incidence rate of gestational diabetes was 8.5% (826/9630). Of women with gestational diabetes, 21.3% accepted to return and completed postpartum screening tests in the first recall. The distance from the cohort center, history of diabetes in the family, and a number of pregnancies were significant predictors for return to follow-up using binary logistic regression (P < 0.01). The first 25% of patients had a distance of 2346 m from the cohort center, and all of the mothers referred to the hospital were 0 to 5 km away, i.e., those who did not return were more than 5 km away (95% confidence interval). Overall screening uptake rate was low. Distance from the center of the screening was an essential factor in deciding to return and adhere to postpartum care in women with gestational diabetes. Geographic inequalities must be considered as a risk factor of visiting the healthcare center in addition to individual contributors. A more accessible center may improve the postpartum follow-up rate in women with a history of gestational diabetes.
