BACKGROUND: Prediabetes is increasingly prevalent, and women transitioning through menopause may face a particularly elevated risk of progressing to type 2 diabetes (T2DM). Estrogen deficiency promotes adiposity, insulin resistance, and inflammation, potentially amplifying the metabolic burden of aging. However, the determinants of T2DM in these women remain insufficiently characterized.
METHODS: This retrospective study included 229 prediabetic women evaluated at a tertiary-care hospital and followed for up to 5.5 years. Prediabetes was defined according to ADA criteria and women were classified as premenopausal (< 51 years), early postmenopausal (51-60 years), or late postmenopausal (> 60 years). Clinical and biochemical variables were analyzed for hazard ratios (HR) of T2DM using Cox regression, and Kaplan-Meier curves.
RESULTS: During follow-up, 18% of premenopausal and 35% of postmenopausal women developed T2DM. Higher BMI predicted T2DM in both groups. In postmenopausal women, IGT (HR: 2.59), hypertension (HR: 3.91), lower HDL-C (HR: 0.96), lower vitamin D (HR: 0.93), and reduced eGFR (HR: 0.97) were independently associated with T2DM. Stratification revealed that early post-menopause carried the highest incidence of T2DM. In early post-menopause, higher BMI and uric acid, and lower vitamin D were independent predictors, whereas in late post-menopause, hypertension and reduced eGFR were the strongest determinants.
CONCLUSIONS: Risk Factors associated with progression to T2DM in prediabetic women appear to differ across age-defined menopausal stages. Excess adiposity remains a key factor, whereas early post-menopause is characterized by additional associations with hyperuricemia and vitamin D deficiency. In late post-menopause, hypertension and declining renal function appear to be more prominent. These findings support stage-specific risk assessment and tailored preventive strategies in prediabetic women.
