Is Sex Like Driving? HIV Prevention and Risk Compensation.

Risk compensation has been called the "Achilles' heel" of HIV prevention policies (Cassell et al 2006). This paper examines the behavioral response to male circumcision, a major HIV prevention policy currently being implemented throughout much of Sub-Saharan Africa. Contrary to the presumption of risk compensation, we find that the response due to the perceived reduction in HIV transmission appears to have been a reduction in risky sexual behavior. We suggest a mechanism for this finding: circumcision may reduce fatalism about acquiring HIV/AIDS and increase the salience of the tradeoff between engaging in additional risky behavior and avoiding acquiring HIV. We also find what appears to be a competing effect that does not operate through the circumcision recipient's belief about the reduction in the risk of acquiring HIV.

Violence Against Female Adolescents in Low- and Middle-Income Countries: Evidence From 36 National Household Surveys.

The goal of this article is to provide evidence on the past-year prevalence of violence against female adolescent children age 15 to 17 and test the hypothesis that higher socioeconomic status is associated with lower likelihoods of past-year violence. We used national household surveys from 36 low- and-middle-income countries to provide evidence on the prevalence of violence against 34,901 adolescents age 15 to 17 and logistic regression analysis to measure the association between socioeconomic status and past-year violence against adolescents. Among the sample population, prevalence of physical violence by nonpartners was 10.4% and by partners was 2.8%. Prevalence of sexual violence by nonpartners was 1.8% and by partners was 1.2%. Logistic regression analysis adjusted for country of residence, and demographic characteristics indicated that completing primary school was associated with higher likelihood of physical violence by nonpartner (odds ratio [OR] = 1.13, confidence interval [CI] [1.03, 1.24]) and lower likelihoods of sexual violence by nonpartner (OR = 0.66, CI [0.53, 0.83]), physical violence by partner (OR = 0.59, CI [0.49, 0.70]), and sexual violence by partner (OR = 0.48, CI [0.36, 0.63]). Total consumer durables owned was associated with reduced likelihoods of physical violence by nonpartner (OR = 0.96, CI [0.94, 0.98]), by partner (OR = 0.88, CI [0.84, 0.93]), and sexual violence by partner (OR = 0.91, CI [0.85, 0.99]). Overall, violence against adolescents as reported in the past-year experience of females age 15 to 17 is common. Primary school completion and household wealth may convey protective benefits against violence.
