Community Violence Exposure and Adolescent Pregnancy in Chicago

This study examined the association between community violence exposure (CVE), sex without contraception, and adolescent pregnancy in Chicago. A self-administered, online survey was conducted among 15- to 19-year-old girls from the South and West sides of Chicago from October to March 2018. Participants were recruited via community organization partnerships and social media advertising. The survey included questions about CVE, sexual behaviors, and covariates that are known to contribute to sexual risk taking. CVE was measured via a validated index of seven questions that measured individual experiences with violence. Multivariable and logistic regression analyses were performed to examine the association between CVE, penile-vaginal intercourse without contraception, and ever being pregnant. The final sample included 644 girls. Levels of CVE were high: 62.87% of girls reported that a close friend or relative died because of violence and 41.60% were a victim of violence. Nearly half (48.69%) of girls had penile-vaginal intercourse and 6.01% had been pregnant. For each standard deviation increase in CVE score, the odds of penile-vaginal intercourse without contraception (odds ratio [OR] = 1.69, 95% confidence interval [CI] = [1.27, 2.25]) and the odds of ever being pregnant (OR = 1.87, 95% CI = [1.36, 2.57]) increased. These results remained significant when adjusting for demographic, psychosocial, institutional, and interpersonal factors. Findings suggest that girls in Chicago who are exposed to higher levels of community violence have an increased likelihood of experiencing penile-vaginal intercourse without contraception and teenage pregnancy, even when adjusting for other predictors to teenage pregnancy.
