New insights into why sexually experienced girls resume sexual activity after periods of abstinence have been offered by researchers at Indiana University School of Medicine.
This information may help tailor effective counseling to prevent sexually transmitted diseases (STDs) and pregnancy in high school girls and beyond.
Characteristics associated with the risk of a teen girl having sex after a period of abstinence differed according to how long she had been abstinent.
In the short term, a young woman was more likely to have sex when her relationship with her partner was good, when the girl felt good and when she was interested in having sex.
Long term, sexual interest and relationship quality were the two most important predictors of resumption of sex after a period of abstinence.
"Sexuality is an important developmental task for teens. They need to go from childhood to sexually mature adulthood while remaining sexually disease free and without getting pregnant. We conducted this study to better understand the factors that influenced teenage girls who became sexually active again after a period of abstinence. With this new understanding we can better help young women remain healthy and avoid unwanted pregnancy," said study first author Dr. Mary A. Ott.
Diagnosis of a STD was associated with a reduced risk of subsequent sex for a short time. However having an STD increased risk for sexual activity in the intermediate time period and was unrelated to the decision to have sex in the long run.
The researchers predicted that the switch may reflect either relationship turmoil after diagnosis of an STD, followed by "make up" sex, or may reflect adherence to Center for Disease Control and Prevention recommendations for a period of abstinence following STD treatment, followed by resumption of previous sexual activity.
"Either way, the findings suggest that counseling only about abstinence after a sexually transmitted infection is insufficient. Clinicians should anticipate resumption of sexual behavior and tailor counseling appropriately," said Ott.
The researchers also found that, in the short term, girls who characterized themselves as irritable, angry or unhappy were unlikely to return to sexual activity after a period of abstinence.
The finding contradicts anecdotal information that depressed individuals are likely to engage in sexual activity.
The researchers evaluated 354 sexually active urban teen girls for up to four and a half years between 1999 and 2006.
Participants reported a total of 9,236 abstinence periods, which averaged 31 days.
"Having data from the same group of young women over such a long period of time, as they go through periods of having sex and times when they are not having sex and as they change partners, enables us to understand a complex process of motivation in a way that previous studies have not. What we have established in this study are the major factors associated with the decision to resume sex," said study senior author Dr. J. Dennis Fortenberry.
The findings have been published in the latest issue of Perspectives on Sexual and Reproductive Health.
