HIV risk among a sample of Mexican and Puerto Rican men and women.

HIV/AIDS has disproportionately affected the Hispanic communities in the United States. Consequently, Hispanic communities at risk for HIV infection should be considered a high priority for prevention and education efforts. Although such efforts ideally consider variations across subpopulations, including differences in high-risk behaviors and routes of transmission by national origin, gender, and acculturation levels, relatively few studies of risk behavior have considered such differences. This paper reports on an interview-based study of HIV knowledge, risk behavior, and protective behaviors among a sample of 143 men and women of Mexican ethnicity in San Diego County, California and 189 men and women of Puerto Rican ethnicity in Cuyahoga County, Ohio. The authors' findings indicate that individuals who have been in the United States for longer periods of time and who are younger in age are at increased risk of HIV infection. Increased perceived risk may also be predictive of increased actual risk.
