A Kaiser Permanente study of 16,000 women in Hawaii has revealed that more than 10 percent of women of Chinese and Korean heritage may be at risk for developing diabetes during pregnancy.
The study also found that Korean-American and Chinese-American women's gestational diabetes risk is one-third higher than average-and more than double that of Caucasian and African-American women.
AdvertisementUntreated gestational diabetes mellitus can lead to serious pregnancy and birthing complications, including early delivery and C-sections. It can also increase the child's risk of developing obesity later in life.
While previous studies have shown that GDM is more prevalent among Asian women and Pacific Islanders, this is the first study to separate those ethnic groups into sub-categories to find out who is at higher risk.
Researchers chose Hawaii for the study because it has one of the most ethnically diverse populations in the world.
Researchers divided Asians into five ethnic sub-groups and found some striking differences: Korean and Chinese women have the greatest risk of developing GDM.
Filipinos are next, but Japanese and Vietnamese women have the same risk as the rest of the population. Among three groups of Pacific Islanders, Samoans and other Pacific Islanders (including women from Fiji and Tahiti) have a higher-than-average risk, while women classified as Native Hawaiians are at average risk.
Caucasian, Native-American, and African-American women have the lowest risk for developing GDM.
"This study has important implications for diagnosis and treatment of gestational diabetes. All pregnant women and their caregivers need to be educated about gestational diabetes, but it is especially important for women in these ethnic groups at higher risk," said study lead author Kathryn Pedula, a researcher at the Kaiser Permanente Center for Health Research.
The study appears in the December issue of the Ethnicity and Disease journal.
