Relative power between sexual partners and condom use among adolescents.

PURPOSE: To examine how the relative power of adolescent sexual partners in the domain of emotional intimacy is related to condom use. METHODS: Interviewed 228 adolescents who visited an STD clinic in San Francisco. Adolescents were aged 14-19 years, 69% were female, and they were ethnically diverse. We developed a measure of relative power in the domain of emotional intimacy, by adapting five items from existing measures and developing three items ourselves. The partner who had less desire for emotional intimacy was considered to have more power in that domain. We also measured relative decision-making power. Data were analyzed using logistic regression and Student's t-tests. RESULTS: Adolescents who had more power than their partners in the domain of emotional intimacy were more likely to get their way about condom use than adolescents who had less power in this domain. Decision-making power was not related to whether adolescents got their way about condom use. Young men reported greater emotional intimacy power and greater decision-making power than young women. However, gender was not related to getting one's way about condom use. CONCLUSIONS: The results suggest the importance of assessing relative power in the sexual relationships of adolescents when predicting condom use.

Adolescent condom use and perceptions of risk for sexually transmitted diseases: a prospective study.

BACKGROUND: The authors' previous research has shown that in cross-sectional analysis, partner-specific perceptions of risk for gonorrhea and chlamydial and HIV infection correlated with partner-specific intentions to use condoms. GOAL: The goal was to determine whether partner-specific measures of perception of risk for STDs (PRSTD) predict partner-specific condom use 6 months later among high-risk and low-risk youth. STUDY DESIGN: Youths aged 14 to 19 years were recruited from an STD clinic (n = 236) and an HMO teen clinic (n = 306) and were interviewed at baseline and at 6 months about PRSTD, attitudes about condoms, self-efficacy, normative expectations, and condom use. RESULTS: PRSTD with a main sex partner was an independent predictor of condom use with a main sex partner in the STD clinic cohort (odds ratio = 2.5; 95% CI = 1.1-6.2). There was no association between PRSTD with a casual sex partner and condom use in this cohort or between PRSTD for main or casual sex partners and condom use in the HMO teen clinic cohort. CONCLUSION: Interventions that target high-risk adolescents should focus on PRSTD with a main sex partner.

The trade-off between hormonal contraceptives and condoms among adolescents.

CONTEXT: Adolescents' dual use of condoms and hormonal contraceptives is low, and the motivations underlying their decisions to combine contraceptives are not understood. METHODS: To examine how pregnancy concerns, sexually transmitted disease (STD) concerns and type of sexual partner influence contraceptive use, we recruited 436 sexually experienced adolescents from two clinics. In structured interviews, we asked adolescents to describe their recent partners, their method use, and their pregnancy and STD concerns. Data were analyzed using logistic regression. RESULTS: The odds that adolescents used condoms with main partners were significantly lower among those who used hormonal contraceptives than among nonusers of these methods (odds ratios, 0.4 for young women and 0.3 for young men). With casual partners, no association existed between adolescents' condom and hormonal contraceptive use. Concerns about pregnancy and STDs influenced this association for women with main partners. Among young women who perceived pregnancy as more negative, hormonal contraceptive users had reduced odds of using condoms (0.1). No association existed between use of the two methods among young women whose view of pregnancy was less negative. Young women who perceived themselves to be less at risk of acquiring an STD had reduced odds of using condoms if they were using hormonal contraceptives (0.2). Among young women who perceived themselves to be more at risk of acquiring an STD, no association existed. CONCLUSIONS: Adolescents trade off between hormonal contraceptives and condoms according to partner type and perceived risks. Adolescents' dual-method use may improve if providers tailor counseling to adolescents' perceived risk of STDs and pregnancy, and if they address prevention of both as a related decision.
