Early menstruation linked to gestational diabetes

Finding could help identify those at risk

Early menstruation could flag a later risk of gestational diabetes mellitus, new research* shows.

Researchers at the University of Queensland’s School of Public Health researchers analysed data from more than 4,700 women from the Australian Longitudinal Study on Women's Health and found that a higher number of women who reported having their first period at a younger age had later developed gestational diabetes.

Researcher Danielle Schoenaker said those who had their first period at age 11 or younger were 50% more likely to develop gestational diabetes than those who experienced their first period at age 13.

"This finding could mean that health professionals will start asking women when they had their first period to identify those at higher risk of gestational diabetes," Ms Schoenaker said.

Australian Longitudinal Study on Women's Health Director Professor Gita Mishra said early puberty in girls had now been shown to be a significant marker for several adverse health outcomes, including gestational diabetes.

"Research into this topic is of particular public health importance due to global trends of girls starting their menstrual cycles at a younger age," Professor Mishra said.

Ms Schoenaker said the significant association with gestational diabetes risk remained after researchers took into account body mass index and childhood, reproductive and lifestyle factors.

"A large proportion of women who develop diabetes during pregnancy are overweight or obese, and encouraging those with an early start of puberty to control their weight before pregnancy may help to lower their risk of gestational diabetes," she said.

"While a healthy weight is important, it is also plausible that the higher risk is explained by hormonal changes, and the research calls for more studies to investigate the mechanisms behind this.”

The study is published in the American Journal of Epidemiology
