Researchers have developed an accurate method to predict a woman’s likelihood of developing postpartum diabetes.

Gestational diabetes is one of the most common conditions that can occur during pregnancy. Although the symptoms generally disappear after delivery, women suffering from gestational diabetes are at increased risk of developing postpartum diabetes in the following years.

For their study, the scientists from the Institute of Diabetes Research (IDF), Helmholtz Zentrum Munchen in Germany, collected data from 257 cases of gestational diabetes which occurred between 1989 and 1999 and were followed up for a period of 20 years after delivery.

One hundred and ten of the women observed during this period developed postpartum diabetes.

In order to be able to predict in which mother the disease would manifest itself after delivery, the team headed by Anette-Gabriele Ziegler, Director of the Institute of Diabetes Research, tested various parameters that are known to play a significant role in the genesis of the disease.

“Body mass index (BMI) and genetic predisposition both play a role in our calculation, as does the question of whether the mother breastfed her baby and whether her gestational diabetes had to be treated with insulin,” researchers said.

On the basis of these parameters, the researchers introduced a point system to enable them to predict a woman’s likelihood of developing postpartum diabetes.

For low-risk scores, the probability of developing diabetes within five years after delivery was only about eleven per cent; in the medium-risk category it ranged from 29 to 64 per cent, while for the highest-risk scores it was more than 80 per cent.

“The test we developed is very easy to apply and in the future could be used in hospitals as a tool for predicting postpartum diabetes,” Mr Ziegler said.

“This means that both the doctor and the patient are aware of the respective risk, and it allows diabetes checks to be more closely tailored to the patient’s individual needs,” Ziegler said.

The study was published in the journal Acta Diabetologica.
