Although the pattern held true for both genders, the effects were
more pronounced for younger females.
“Adolescents who engage in early sex have higher risks for sexually
transmitted infections or unplanned pregnancies,” lead study author
Dr. Kelly Ann Doran of Indiana University in Bloomington told
Reuters Health by phone. “Although the U.S. has seen a drop in
pregnancy rates, we still have one of the highest in the Western
industrialized world. It’s a big issue, and it’s important to find
the risk factors that lead to risky sex.”
Doran and colleagues analyzed survey data from 4,079 males and 4,059
females who participated in the National Longitudinal Study of Youth
1997. Data collection started when participants were between ages 12
and 16, and it continued periodically until they were 25 to 31 years
old.
On average, boys and girls both had their first drinks before their
15th birthday. The average age for first sexual encounter was 16 for
both genders, the study authors wrote in the Journal of Adolescent
Health.
Onset of drinking before age 14 more than doubled the odds that
adolescents of either gender would have earlier sexual encounters.
For females who had their first drink at 13 or younger, the
likelihood of early sexual initiation quadrupled.
“The association is strong for both males and females,” Doran said.
“It still holds (regardless of) socioeconomic status or poor
parental monitoring, which could mean we see a unique risk with
early drinking.”
“With research, we sometimes think about all of these different
risks as separate and have separate programs for alcohol use or teen
pregnancy, but many of these behaviors are interconnected,” said Dr.
Arielle Deutsch of Sanford Research in Sioux Falls, South Dakota.
Deutsch, who wasn’t involved with this study, has researched the
link between substance use and sexual intercourse among teens.
“We have to really think about all of these behaviors and what
adolescents may be going through during this time in their lives,”
she told Reuters Health by phone.

Future studies should look at the reasons why early drinking may be
linked to earlier sex, such as lowered inhibitions, impaired
decision-making, and peer pressure among social groups, Doran said.
“Impairment from alcohol increases the likelihood of being
victimized or victimizing other people,” she said. “We’d like to do
more research to see if there is any difference for voluntary or
involuntary sex as well.”
The emotional and social context around the first-time sex
experience is important, too, Deutsch added.
“It’s about the relationship between two people and how individuals
think about what they’re doing,” she said. “How do teens think about
planning their first sexual experience?”
“When teens talk about things like drinking, sex, hanging out with
their friends, and partying, it’s all interconnected, especially
with parenting approaches,” Deutsch said. “We should be talking to
teens about how to make good choices overall and have the
experiences they want in life.”
