Certain psychiatric disorders linked with risky sexual behavior in teens

September 28, 2010

Although research has shown that teens with mental health disorders are more likely to engage in high risk sexual behaviors, like unprotected sex, a new study from the Bradley Hasbro Children's Research Center suggests there is an additional risk associated with certain psychiatric diagnoses.

According to researchers, teens who experience the manic phase of bipolar disorder - which is marked by dramatic mood swings from euphoria and elation to irritability - are more sexually active, have more sexual partners and are more likely to have a sexually transmitted infection (STI).

Researchers also found that teens with externalizing disorders (which includes , conduct disorders and angry, defiant or hostile behaviors like stealing) are more likely to be sexually active than their peers, putting them at higher risk for HIV and other STIs. This was true even for teens who also had a co-occurring internalizing disorder, such as anxiety, depression or post-traumatic stress disorder.

The findings were recently published in the .

"Increased sexual risk taking may be linked to these disorders because they're often associated with impulsive or reckless behaviors, which could include multiple sexual partners or not using condoms regularly," said lead author Larry K. Brown, MD, of the Bradley Hasbro Children's Research Center. "Because of their increased vulnerability to HIV and other sexually transmitted infections, the sexual risk behavior of teens with these diagnoses should be carefully and routinely screened as part of their mental health treatment."

Approximately one in four teens in the United States will contract a sexually transmitted disease, according to the . In addition, adolescents with mental health disorders or a history of psychiatric hospitalizations have intercourse at an earlier age, have more unintended pregnancies and have more sexual partners than their peers.

The study included 840 teens and their parents from Providence, Atlanta and Chicago participating in Project STYLE (Strengthening Today's Youth Life Experience) - the first multi-site HIV prevention program designed specifically for parents and youths with significant mental health disorders. All participants completed computer-assisted surveys to gather information about psychiatric symptoms and sexual risk behaviors. Teens also completed urine screens to determine the presence of an STI. More than half of all participants were both female and African-American. The average age was 15.

Overall, the study included 153 teens with a diagnosis of mania, 48 with internalizing disorders, 282 with externalizing disorders, 252 with more than one diagnosis and 105 in treatment who did not meet the criteria for any of the assessed psychiatric diagnoses.

More than half of all participants reported a history of vaginal or anal intercourse. Among those who were sexually active, 29 percent did not use a condom the last time they had sexual intercourse. Approximately 31 percent had been sexually active within the previous 90 days, with an average of two partners each, while 15 percent reporting having four or more partners. Fourteen percent of teens tested positive for a STI.

The study revealed that while teens with an externalizing disorder - even if they have a co-occurring internalizing disorder - do tend to engage in risky sexual behavior, adolescents with mania are at an even higher risk for HIV and STI. These teens had significantly more sexual partners and were four times as likely to have an STI compared to the other groups.

"This is interesting because there's very little information on adolescents with mania," said Brown, who is also a professor of psychiatry and human behavior at The Warren Alpert Medical School of Brown University. "We know that adults with mania are more likely to engage in risky sexual behavior, but we haven't had data like this before for teens."
