['We sought to identify correlates of forced sex perpetration among men and victimization among women in Botswana and Swaziland.', 'We surveyed a 2-stage probability sample of 2074 adults from the 5 districts of Botswana with the highest HIV prevalence rates and all 4 regions of Swaziland. We used multivariable logistic regression to identify correlates of forced sex victimization and perpetration.', 'Lifetime prevalence rates of forced sex victimization of women were 10.3% in Botswana and 11.4% in Swaziland; among men, rates of perpetration were 3.9% in Botswana and 5.0% in Swaziland. Lifetime history of forced sex victimization was the strongest predictor of forced sex perpetration by men in Botswana (adjusted odds ratio [OR] = 13.70; 95% confidence interval [CI] = 4.55, 41.50) and Swaziland (adjusted OR = 5.98; 95% CI = 1.08, 33.10). Problem or heavy drinking was the strongest predictor of forced sex victimization among women in Botswana (adjusted OR = 2.55; 95% CI = 1.19, 5.49) and Swaziland (OR = 14.70; 95% CI = 4.53, 47.60).'] Does prevalence and correlate of forced sex perpetration and victimization in Botswana and Swaziland?
