Follow-up of women with gestational diabetes in the Tehran Lipid and Glucose Study (TLGS): A population-based cohort study

Aim: Women with gestational diabetes (GDM) are at increased risk of developing type 2 diabetes mellitus (T2DM), but there is disagreement regarding this conversion rate or its cardiovascular consequences. We investigated the metabolic and cardiovascular consequences of women with GDM in a population‐based cohort study. Material and Methods: Three groups of women were selected from the Tehran Lipid and Glucose Study (TLGS) and followed up for an average 9 years: women with prior history of GDM (n = 29); women with history of macrosomia or stillbirth without GDM (MC‐ST) (n = 570), and age‐ and BMI‐matched controls (n = 628). The incidence of T2DM, hypertension (HTN) and dyslipidemia were compared between these groups. Statistical significance was set at P
