Preemies Raise U.S. Infant Mortality Rate

High Percentage of Premature Births Contributing to Nation's High Infant Mortality Rate, Report Shows

Preterm Births Driving Infant Mortality Rate continued...

The U.S. infant mortality rate, MacDorman and colleagues report in the article, is mainly attributable to an increase in preterm births. Preterm births are at much higher risk for death or disability than full-term births.

“We don’t know why the preterm rate is so much higher than in Europe,” MacDorman tells WebMD. “But teens, older mothers, smokers all have higher preterm rates.” The percentage of preterm births in 2004 was 12.4% for the U.S., which was much higher than the selected European countries, such as 5.5% for Ireland, 6.3% for France, and 8.9% for Germany.

When births after less than 22 weeks are excluded, the U.S. and other countries show a drop in infant deaths in 2004. However, the U.S. still has an infant mortality rate higher than most European countries, with nearly twice the rate of Sweden and Norway.

Since 1960, the infant mortality rate in the U.S. has been worsening, the researchers report. The U.S. international rate was 12th in 1960, fell to 23rd in 1990, to 29th in 2004 and 30th in 2005. In that year, 22 countries had infant mortality rates of 5.0 or lower per 1,000 live births.

The researchers say that some countries have limits on birth registration requirements, and very small infants who die soon after birth are excluded in some data.

“The majority of infants born at 22-23 weeks of gestation die in their first year of life,” the article says.

Even for full-term infants, the U.S. rate was high at 2.4 per 1,000 births, compared to other countries.
