Reducing sexual risk behavior in adolescent girls: results from a randomized controlled trial

PURPOSE

Teenage girls in low-income urban settings are at an elevated risk for HIV, sexually transmitted infections, and unintended pregnancies. The purpose of this study was to evaluate the efficacy of a sexual risk-reduction (SRR) intervention, supplemented with postintervention booster sessions, targeting low-income, urban, sexually active teenage girls.

METHOD

Randomized controlled trial in which sexually active urban adolescent girls (n = 738) recruited in a midsize northeastern U.S. city were randomized to a theory-based SRR intervention or to a structurally equivalent health promotion control group. Assessments and behavioral data were collected using audio computer-assisted self-interview at baseline, then at 3, 6, and 12 months postintervention. Both interventions included four small-group sessions and two booster sessions.

RESULTS

Relative to girls in the control group, girls receiving the SRR intervention were more likely to be sexually abstinent; if sexually active, they showed decreases in (a) total episodes of vaginal sex at all follow-ups, (b) number of unprotected vaginal sex acts at 3 and 12 months, and (c) total number of sex partners at 6 months. Medical record audits for girls recruited from a clinical setting (n = 322) documented a 50% reduction in positive pregnancy tests at 12 months.

CONCLUSIONS

Theory-based behavioral interventions tailored to adolescent girls can help to reduce sexual risk and may also reduce unintended pregnancies. Although sexually active at enrollment, many of the girls receiving the intervention were more likely to practice secondary abstinence. Continued refinement of SRR interventions for girls is needed to ensure they are feasible, appealing, and effective.

Contraceptive choices in HIV infected and HIV at-risk adolescent females

PURPOSE

To describe reported contraception use in HIV infected and HIV uninfected but at-risk female adolescents, and determine associations with the reported consistent use of effective contraception methods, including its association with pregnancy.

METHODS

HIV infected and at-risk female youth, aged 13-18 years, who were sexually active and reporting no intention to become pregnant, were included. Contraception use data from three consecutive visits (approximately 6 months apart) were used.

RESULTS

Ninety-four percent of HIV infected and 89% of at-risk subjects reported choosing a main contraception method with demonstrated efficacy when used consistently. Approximately 50% chose partner condoms. HIV infected youth were more likely to report 100% partner condom use in the past 3 months (73% vs. 46%; OR 3.3; 95% CI: 1.7-5.6). At-risk youth were 2.5 times more likely than HIV infected subjects to report using nothing (95% CI: 1.1-5.8). Slightly more than half (56%) demonstrated the consistent reporting of effective methods (CREM) of contraception. In multivariate analysis, HIV infection (OR 4.0; 95% CI: 2.2-8.2) and African-American race (OR 2.7; 95% CI: 1.1-6.6) were significantly associated with CREM. Subjects reporting inconsistent or unreliable contraception use had higher 1-year pregnancy rates than CREM subjects (32% vs. 14%; p = .002).

CONCLUSIONS

Only half of HIV infected and at-risk youth reported using effective contraception consistently, despite its availability. Additionally, regardless of reported contraceptive use, the rates of unplanned pregnancy were unacceptably high.

Reproductive health: an international perspective

The twentieth century began with approximately 1.6 billion human beings in the world and, with an increase of 96 million people per year, will end with over 6 billion people. Unless this trend is directly confronted by the world governments and their citizens, there will be nearly 8 billion by 2025 and over 11 billion by 2050. Thus, reproductive health is and will remain an issue of critical importance for all countries to realize and study. Part of this trend is because of the many pregnancies which occur in adolescents around the world. A number of issues have developed this century contributing to the many pregnant teenagers. For example, India has one of the world's largest populations of teenagers--over 23 million, representing over 26% of the total in the world. Effective methods for contraception and sexually transmitted diseases prevention are available, but not to all sexually active humans. However, many barriers to effective contraception exist around the globe. This article discusses some of them and also reviews use of contraceptive methods in various countries. These include oral contraceptives, emergency contraceptives, injectable and implantable contraceptives, intrauterine devices, barrier contraceptives and others. Reproductive health remains a critical, universal issue for all humans in the world. We all must examine the many pitfalls to controlling the world's populations, including lack of sex education, limited access to effective contraceptives, and others. We cannot afford to let the population continue unchecked. Effective strategies are needed at this time; otherwise, the population will continue to run out of control, negatively damaging the world for the coming generations. There is need to leave a positive, and not negative legacy for the next generation.
