Twinning is winning: Moms of twins live longer
Date: 12.5.2011
Compared with other mothers, women who deliver twins live longer, have more children than expected, bear babies at shorter intervals over a longer time, and are older at their last birth, according to a University of Utah study. The findings do not mean having twins is healthy for women, but instead that healthier women have an increased chance of delivering twins, says demographer Ken. R. Smith, senior author of the study and a professor of family and consumer studies.
"Having twins will not make you stronger or healthier, but stronger, healthier women are more likely to have twins naturally," says Shannen Robson, the study's first author and a recent Ph.D. graduate in anthropology at the University of Utah.
The study, funded by the National Institute on Aging, was scheduled for online publication Wednesday, May 11 in the journal Proceedings of the Royal Society B.
