More women are waiting until later in life to have children, U.S. health officials reported Friday.
The birth rate for women in their 30s and early 40s rose in 2012, even as birth rates for teenagers and young adults declined to record lows, according to figures released by the U.S. Centers for Disease Control and Prevention.
The rise in the number of births to older women was not surprising to Dr. Edward McCabe, chief medical officer for the March of Dimes.
“If we just look at our anecdotal experience with women who are friends and colleagues, we know a lot of women are delaying birth until later in life,” McCabe said.
Preterm births fell in 2012, as they have done since 2006, the CDC reported. This news comes during the 10th anniversary of the March of Dimes’ campaign to reduce preterm births, McCabe said.
“Back in 2003, it was quite lonely because it seemed like rising prematurity [was] one of those intractable problems,” he said, noting this is the sixth consecutive year that the preterm rate has decreased.
There were about the same overall number of births in 2012 as the year before — 3.95 million — arresting a decline in the United States birth rate that had occurred between 2007 and 2011.
Birth rates for women aged 30 to 34 increased by 1 percent in 2012 to about 97 births per 1,000 women, while the birth rate for women aged 35 to 39 increased by 2 percent to about 48 births per 1,000 women.
The birth rate for women aged 40 to 44 also increased by 1 percent, to 10.4 births per 1,000 women.
McCabe said the trend toward having children later in life is somewhat troubling, given that the risk of birth defects, autism and other childhood disorders increases with maternal age.
