Twin births rising, especially for older women, CDC says
More parents are seeing double these days — and federal data released today explains why: The number of twin births in the USA more than doubled from 1980 to 2009.
An analysis of three decades of twin births (2009 data are the most recent year included) finds large increases in twin birth rates for all age groups, among all racial and ethnic groups and in all states and the District of Columbia. The overall U.S. twin birth rate increased 76%, from 18.9 in 1980 to 33.2 per 1,000 births in 2009.
And for mothers age 35 and over, those twin rates have skyrocketed. Among women 35-39, rates rose by nearly 100%, and among those 40 and over, rates rose more than 200%, finds the report from the National Center for Health Statistics, part of the Centers for Disease Control and Prevention.
While the chance of having twins does increase with a mother's age, the report suggests that fertility treatment provides the backdrop for this baby bonus, says CDC statistician Joyce Martin.
