Government report also shows Cesarean deliveries hitting new highs

WEDNESDAY, March 18 (HealthDay News) -- The number of unmarried women who are having babies has reached a record level in the United States, and Cesarean delivery rates continue to hit new highs, a government report shows.

The total number of births, birth rate and proportion of births to unmarried women all increased by 3 percent to 5 percent from 2006 to 2007. The estimated 1,714,643 babies born to unmarried women in 2007 accounted for 39.7 percent of all births in the country.

The total number of births rose to 4,317,119 in 2007, the highest number of births ever registered in the United States. The Cesarean delivery rate increased by 2 percent, to 31.8 percent, in 2007 -- the eleventh consecutive year of increase and another record high for the nation, said the report from the National Center for Health Statistics at the U.S. Centers for Disease Control and Prevention.

Among the other findings:

• The percentage of low birth-weight babies (less than 2,500 grams) decreased, from 8.3 percent in 2006 to 8.2 percent in 2007. Over the past few decades, low birth weight rates have steadily risen; this is the first decline since 1984.
• The rate of preterm births (babies delivered after less than 37 weeks of pregnancy) decreased 1 percent, to 12.7 percent in 2007. The decline occurred predominately among infants born late preterm (between 34 and 36 weeks). Since the early 1980s, the preterm rate in the United States has increased by more than a th
