STANFORD, Calif. - Pregnant women who are part of an Asian-white couple face an increased risk of gestational diabetes as compared with couples in which both partners are white, according to a new study from Lucile Packard Children's Hospital and the Stanford University School of Medicine.
The researchers also found that Asian women whose partners are white are more likely than white women with Asian or white partners to have a caesarean delivery, as part of a broad analysis of perinatal outcomes among Asian, white and Asian-white couples.
More specifically, the researchers found that white mother/Asian father couples had the lowest rate (23 percent) of caesarean delivery, while Asian mother/white father couples had the highest rate (33.2 percent). Because birth weights between these two groups were similar, the researchers say the findings suggest that the average Asian woman's pelvis may be smaller than the average white woman's and less able to accommodate babies of a certain size. (Asian couples had babies with the lowest median birth weight, so caesarean delivery was less common among those women.)
El-Sayed and his colleagues also found that the incidence of gestational diabetes was lowest among white couples at 1.61 percent and highest among Asian couples at 5.73 percent - and just under 4 percent for Asian-white couples. These findings weren't altogether surprising: past studies have shown an increased risk of diabetes among Asian couples, which researchers attribute to an underlying genetic predisposition. But the interesting finding, El-Sayed said, was that the risk for interracial couples was about the same regardless of which parent was Asian.
