Teen Births Rose in 2006

The teen birth rate in the U.S. rose for the first time in
14 years in 2006, and the number of cesarean deliveries and births to unmarried
women hit all-time highs, according to the CDC's National Center for Health
Statistics (NCHS).

Teen childbirths rose by 3% in 2006, to about 42 births for every 1,000
females between the ages of 15 and 19.

That was up from 40.5 births per 1,000 in 2005, but still well below the 62
births per 1,000 recorded in 1991, when teen birth rates began their
decade-plus decline.

About 20,000 more births were recorded among teens in the U.S. in 2006 than the previous year, with
a 5% increase seen among African-American teens, a 3% increase among
non-Hispanic whites, and a 2% increase among Hispanics.

While it is too early to say if the rise represents the beginning of a
trend, Stephanie J. Ventura, who heads the NCHS reproductive statistics branch,
says it is cause for concern.

"This could continue or it could reverse, but it is not the direction we
want to see," she tells WebMD.

New Baby Boom?

Overall, the birth rate increased by 3% to 4.26 million between 2005 and
2006, the largest single-year increase since 1989 and the largest total number
of births since 1961, which was one of the last years of the baby boom.

Birth rates rose by 4% among women between the ages of 20 and 24, to 105
births per 1,000 and by 3% among those aged 40 to 44, to 9.4 births per
1,000.

An increase in the total fertility rate, which represents an estimate of the
number of children a woman will have over her reproductive life, may be one
explanation for the increase in overall births, Ventura suggests.

She says the rise represents a reversal in a trend, as an increasing number
of families are made up of more than one or two children.

So when it comes to family planning, three may be the new two.

"I've heard people say that," she says. "All we can say is that
the fertility rate is higher than it has been."

Record Cesarean Deliveries, Unmarried Moms

In 2006, nearly one in three babies in the U.S. was delivered by cesarean section .

The C-section rate rose by 3% to 31.1% -- more than twice the target rate
government health officials have called for among low-risk women by 2010.

C-sections were relatively rare in the U.S. before 1970, when just 5% of
babies were delivered surgically.

By the mid-1980s, nearly one in four babies born in the U.S. was delivered
by cesarean section. That number dipped slightly through the 1990s, but has
been climbing steadily ever since.

The increase in births among unmarried women is definitely a trend, Ventura
says. Births among this group hit historic highs in 2006.

The 1.6 million births among unmarried women represents an 8% increase over
2005 and is 20% higher than the recent low point for births in the group seen
in 2002.

"Most of this increase is in women in their 20s," Ventura says.
"This definitely suggests a change in attitudes about the issue."

Preterm Deliveries Rising

The preterm birth rate rose slightly in 2006, to 12.8% from 12.7% the
previous year, and low-birth weight deliveries rose from 8.2% to 8.3%.

Preterm births and low-birth rate deliveries have risen by 21% and 19%,
respectively, since 1990, with late preterm births of between 34 and 36 weeks
gestation rising by 25%, the NCHS's Joyce A. Martin, MPH, tells WebMD.

Though the reasons for this are not completely clear, Martin says one factor
appears to be an increased willingness among health care providers to induce labor early.

The rate of infant deaths remained at a relatively stable 6.9 per 1,000 live
births between 2004 and 2005, the last year for which mortality data have been
analyzed.

African-American newborns continued to be more than twice as likely as white
and Hispanic infants to die in te first year of life.

More than half of all infant deaths in 2005 were from
birth defects , premature delivery, sudden infant death syndrome, and
complications at delivery.

Life Expectancy Still Rising

There were 2.44 million deaths in the United States in 2005, an increase of
about 50,000 deaths over 2004.

Life expectancy continued to increase to a record high of 77.9 years in
2005, or 0.1 year more than the previous year.

The life expectancy for a white female born in 2005 is now 80.8 years,
compared to 75.7 years for a white male, 76.5 years for a black female, and
69.6 years for a black male.
