U.S. Women Delay Motherhood
Preterm births, low birth weight babies declined in 2011, report says

FRIDAY, June 28 (HealthDay News) -- As American women continue to delay parenthood, rates of teenage births and births for women in their early 20s are at all-time lows, federal health officials reported Friday.
U.S. women have their first baby at age 25.6 on average, according to 2011 figures released by the U.S. Centers for Disease Control and Prevention (CDC). This is up slightly from 2010 and significantly older than the 1970 average of 21.4 years.
Births to girls 15 to 19 declined 8 percent between 2010 and 2011, and births to women 20 to 24 years old dropped 3 percent to a record low, the CDC report stated.
"If this [trend] results in more births being planned and intended it is difficult to object to it," said Dr. Jeffrey Ecker, director of Obstetrical Clinical Research and Quality Assurance at Massachusetts General Hospital in Boston.
"If we are talking about a shift from early 20s to late 20s or early 30s, the expectation is that outcomes would be safe and healthy. The message isn't that it's fine to wait until a woman is in her late 30s or 40s to think about becoming pregnant," added Ecker, who is also chair of the American College of Obstetricians and Gynecologists' Committee on Obstetric Practice.
As women get older it is more difficult to become pregnant, Ecker said, adding that the likelihood of miscarriage and other complications also increases.
Overall, 3.9 million U.S. births were reported in 2011, representing the lowest general birth rate since 1998 -- 63.2 births per 1,000 women aged 15 to 44 -- and 1 percent less than in 2010, the CDC reported.
Birth rates were unchanged for women aged 30 to 34 but rose for women 35 to 44.
Births to unmarried women declined in 2011 for the third year in a row -- down another 2 percent from 2010.
Experts found good news in the report.
In terms of health, highlights are a leveling off of cesarean births and the continued decline in the preterm birth rate, said lead author Joyce Martin, an epidemiologist at CDC's National Center for Health Statistics, Division of Vital Statistics, Reproductive Statistics.
