Gestational diabetes carries risks beyond the period of pregnancy.

Women who develop gestational diabetes are ten times more likely to develop type 2 diabetes in later life, but only a third of these women realise they’re at high risk.

Researchers from the University of South Australia and University College Dublin recently examined the views of 429 Australian women with a history of gestational diabetes, to establish their perceived risks of developing type 2 diabetes, potential barriers to losing weight, and useful strategies going forward.

Prevention is key

Lead researcher, UniSA’s Kristy Gray said understanding the risks of developing type 2 diabetes post-gestational diabetes is essential, as prevention is the key.

‘Gestational diabetes is the fastest growing type of diabetes in Australia, affecting thousands of pregnant women each year; and globally, it affects almost one in five pregnancies,’ said Ms Gray.

‘Women who’ve had gestational diabetes are ten times more likely to develop type 2 diabetes, but only a third of these women understand that they are at high risk,’ she said.

‘Being overweight is a common risk factor for developing type 2 diabetes, making post pregnancy weight loss important in preventing onset of this disease.

‘In our study, while 75 per cent of the women surveyed understood that they were overweight, this knowledge didn’t translate into a high level of perceived risk,’ concluded Ms Gray.


Education and lifestyle important

Co-researcher, UniSA’s Associate Professor Jennifer Keogh said diabetes prevention strategies must embrace both education and lifestyle.

‘Women diagnosed with gestational diabetes often have a young family, which means any interventions need to be considered in line with small children, busy lifestyles and multiple priorities,’ said Associate Professor Keogh.

‘The priority is to educate both women with gestational diabetes, and the health professionals who care for them, to ensure greater communication and boost awareness of the risk factors these women have.

‘This is critical, as close to a quarter of women in this study had not been tested for type 2 diabetes following a pregnancy with gestational diabetes.

‘We also know that the most effective time to initiate and commit to healthy lifestyle and behaviour changes is up to two years post pregnancy, so interventions are likely to be more effective during this time frame,’ she said.

‘Motivation to lose weight is a significant barrier to change – whether it be because of a busy family or because a lifestyle change can be hard to stick to – consistent education, strong messaging and personalised care, can instigate positive change.

‘Prevention is the key; making sure women’s needs, views, and situations are considered is an essential part of the solution,’ said Associate Professor Keogh.
