Maternal hyperandrogenism is associated with a higher risk of type 2 diabetes mellitus and overweight in adolescent and adult female offspring: a long-term population-based follow-up study.

purposeAdverse intrauterine environment may predispose offspring to cardio-metabolic dysfunction in later life. In this study, we aimed to investigate the effects of maternal hyperandrogenism (MH) on cardio-metabolic risk factors in female offspring in later life.

methodsThis prospective population-based study included 211 female offspring with MH and 757 female offspring without MH (controls). Both groups were followed from baseline to the date of incidence of events, censoring, or end of the study period, whichever came first. Age scaled unadjusted and adjusted cox regression models were applied to assess the hazard ratios (HR) and 95% confidence intervals (CIs) for the association of MH with pre-diabetes (pre-DM), type 2 diabetes mellitus (T2DM), overweight and obesity in offspring of both groups. Statistical analysis was performed using the software package STATA; significance level was set at P < 0.05.

resultsThis study revealed a higher risk of T2DM (unadjusted HR 2.67, 95% CI 1.33-5.36) and overweight (unadjusted HR 1.41, 95% CI 1.06-1.88) in female offspring with MH, compared to controls. Results remained unchanged after adjustment for potential confounders including body mass index, education, physical activity, mother's age at delivery, birth weight, and childhood obesity. However, no significant difference was observed in the risk of pre-DM and obesity in females with MH, compared to controls in both unadjusted and adjusted models.

conclusionThis pioneer study with a long-term follow-up demonstrated that MH increases the risk of developing T2DM and being overweight in female offspring in later life. Further long-term population-based studies are needed to confirm these findings.
