More than 1 in 10 immigrant women develop gestational diabetes

“Maternal world region of birth may help us to better identify in early pregnancy those immigrant women at highest risk for developing GDM, and who might benefit from dietary and activity modification in early pregnancy,” says Institute for Clinical and Evaluative Sciences (ICES) researcher and St. Michael’s Hospital physician Dr. Joel Ray.

The study looked at the risk of GDM among a large and diverse cohort of 770,875 consecutive deliveries in Ontario, including 118,849 deliveries among immigrants and found:

  •     Canadian-born women had 3 per cent rate of GDM.
  •     Immigrant women from the Middle East and North Africa had a 1.7 times higher risk of developing GDM than Canadian-born women.
  •     Women from East Asia had a 2 times higher risk of developing GDM than their Canadian-born counterparts.
  •     Women from South Asia had a 3.5 times higher risk of GDM compared to Canadian-born women.

“These findings might also help in deciding which women should be screened for adult-onset (type 2 diabetes), since GDM is a well recognized long-term risk factor for type 2 diabetes,” says Ray.

The research letter “Gestational Diabetes Among Immigrant Women,” is being published in the November issue of Epidemiology.
