Sweden updates gestational diabetes thresholds
Key Points
  • 6.5% of women giving birth in 2024 diagnosed with gestational diabetes, rates rising and varying by region
  • Only 7 of 21 regions follow previous WHO-based thresholds; most used higher thresholds
  • New national recommendations update thresholds and introduce earlier testing for high-risk women

Only 7 out of 21 regions follow the National Board of Health and Welfare's previously recommended diagnostic thresholds, which were based on World Health Organization (WHO) guidelines. Most regions used significantly higher thresholds than the WHO recommendations, according to multiple reports.

The National Board of Health and Welfare has issued new recommendations and updated thresholds for gestational diabetes. The new recommendations mean that pregnant women at increased risk can be offered testing earlier in pregnancy. Those at higher risk include women with a BMI over 30, those who have previously given birth to a large baby, or those with first-degree relatives with diabetes, according to multiple reports.

This could mean that pregnant women with similar blood sugar levels receive a diagnosis and follow-up in one region, but not in another. The purpose of our new recommendations is that more people should receive support early and that care should become more equitable across the country.

"This could mean that pregnant women with similar blood sugar levels receive a diagnosis and follow-up in one region, but not in another," said Sofia von Malortie, unit manager at the National Board of Health and Welfare. "The purpose of our new recommendations is that more people should receive support early and that care should become more equitable across the country."

Those diagnosed with gestational diabetes according to the updated thresholds should receive treatment if needed, the board said. The new recommendations aim to ensure more people receive support early and that care becomes more equitable across the country, according to the board.

When the condition is detected early, there are good opportunities to work with preventive measures. If more pregnant women are tested, it can provide health benefits over time through fewer complications and reduced risk of future disease for both mothers and children.

Gestational diabetes increases the risk of complications during pregnancy and childbirth, such as preeclampsia, cesarean section, and the baby being born larger than normal. Children of mothers with gestational diabetes have an increased risk of overweight and affected metabolism. "If the fetus is exposed to high blood sugar during pregnancy, the fetus grows more. These fetuses often become large in a disproportionate way, on the shoulders and upper body," von Malortie said. "It becomes like a snowball effect."

Gestational diabetes is closely linked to lifestyle habits and societal trends, such as more sedentary lifestyles and dietary habits. "Pregnancy is an important opportunity to identify risks early and offer support regarding, for example, lifestyle habits," von Malortie said.

Knowing how large a proportion has it is part of the problem. Different regions use different thresholds and measure in slightly different ways.

This of course creates anxiety for those patients.

But it also means that if you can reverse the trend. If you can treat this and get a healthier mother, then you can get a healthier child. Then you affect the health of that entire family for many years to come.
