Weight gain after GDM linked to type 2 diabetes

Women who had gestational diabetes mellitus and gained weight after pregnancy were significantly more likely to progress to type 2 diabetes, according to a study.

Among the 1,695 women in the Diabetes & Women’s Health study with a history of gestational diabetes mellitus (GDM), researchers documented 259 incident cases of type 2 diabetes during up to 18 years of follow-up. Each 1 kg/m² increase in baseline body mass index was associated with a 16% higher risk of type 2 diabetes (hazard ratio, 1.16).

Each 5 kg of weight gain after the development of GDM was associated with a 27% higher risk of type 2 diabetes (HR, 1.27).

“Our findings provide evidence to support the recent call from the [National Diabetes Education Program] and highlight the importance of achieving and maintaining a healthy weight in these high-risk women to prevent future development of type 2 diabetes,” the researchers wrote.

The study was supported by the National Institute of Child Health and Human Development, part of the National Institutes of Health.
