The influence of early sexual debut and sexual violence on adolescent pregnancy: a matched case-control study in Jamaica.

CONTEXT: Contraceptive knowledge and use at first sex have increased over time among Jamaican adolescents, yet high unintended pregnancy rates persist. More information on risk factors for adolescent pregnancy is needed to inform programs. METHODS: Structured interviews were conducted with 15-17-year-old females-250 who were currently pregnant and 500 sexually experienced, but never-pregnant, neighborhood-matched controls. Bivariate and multivariate analyses were used to examine associations between adolescent pregnancy and early sexual debut, sexual coercion or violence and sexual risk-taking behaviors. RESULTS: Greater proportions of pregnant youth than of their never-pregnant peers reported having had first sex by age 14 (54% vs. 41%), a first sexual partner who was five or more years older (33% vs. 20%) or multiple partners (63% vs. 50%); a greater proportion of never-pregnant youth had used contraceptives at first sex (88% vs. 80%). Almost half (49%) of all young women reported ever having experienced sexual coercion or violence. Compared with controls, pregnant youth had greater odds of having had an older partner at first sex and believing contraception is a woman's responsibility (odds ratios, 1.3 and 2.1, respectively), and had lower odds of ever having experienced sexual violence and thinking that it is important to protect oneself against pregnancy (0.5 and 0.2, respectively). An interaction between early sexual debut and multiple partners was found. Having had multiple partners was associated with pregnancy only for youth with early sexual debut. CONCLUSIONS: Encouraging adolescents to delay sexual debut and reduce their number of sexual partners may help prevent unintended pregnancies. Experiences of sexual coercion and violence were common among both groups, highlighting the need to address gender-based violence at the community level.

Sexual violence and reproductive health among young people in three communities in Jamaica.

A secondary analysis of data collected from 1,130 young people ages 15 to 24 in a population-based household survey to assess the reproductive health needs of young people in three communities in Jamaica was conducted to determine the relationships among three measures of sexual violence, background variables, three measures of sexual risk taking (early sexual debut, multiple partners, and no condom at last sex), and two reproductive health outcomes (genital discharge within the past 12 months and pregnancy). In the multivariate analyses, forced first sex increased the likelihood of genital discharge among males (odds ratio, OR = 5.33) and females (OR = 2.02) and pregnancy among females (OR = 2.05), controlling for background characteristics and sexual risk taking. Associations between sexual violence and reported genital discharge and pregnancy that were not mediated by our measures of sexual risk taking were found. More research into the causal mechanisms for this association is needed.
