Sometimes, ethnic differences can pose risks for a couple. I was quite surprised by a new finding showing that Asian women married to white men had a 30 percent higher rate of cesarean sections compared with Asian or white couples and white women married to Asian men. The researchers gave a plausible reason why: Previous studies have shown that the average Asian woman's pelvis is smaller than the average white woman's and thus less able to accommodate babies of a certain size. "We're certainly not concluding that these women always need C-sections," says study coauthor Yasser El-Sayed, an obstetrician-gynecologist at Stanford University Medical Center. But he would be less likely to allow a prolonged labor to continue for hours in such women because a vaginal delivery would be very unlikely.
