HIV-infected children with CD4+ T cell percentages > or = 20% responded better to the HAV vaccine if they had undetectable HIV RNA. The standard 2-dose immunization regimen generated low antibody titers with limited persistence. A third vaccine dose was safe and increased the antibody titers, suggesting that an increase in immunizations may be warranted in this population.

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.

The disproportionate impact of HIV/AIDS on Hispanic women in the United States has been variously attributed to a failure to utilize protective measures due to low levels of HIV knowledge, a denial or minimization of risk, and conflicts with cultural norms. It has been hypothesized that women's relative lack of power in relationships may be associated with higher risk sexual behavior. We examined the relationship between higher risk sexual behavior and perceived locus of control in sexual relationships among a sample of Puerto Rican and Mexican women. We interviewed 71 women of self-reported Mexican ethnicity in San Diego, California, and 79 women of self-reported Puerto Rican ethnicity in Cleveland, Ohio, to examine the relationship between HIV risk, HIV knowledge, and locus of control. Univariate logistic regression indicates that among Puerto Rican women, the perception that locus of control in a sexual relationship resides in the male partner was significantly associated with increased HIV risk, while younger age was significantly associated with increased risk among Mexican women only. In a combined sample of both Puerto Rican and Mexican women, multiple logistic regression analysis indicates that younger age, increased length of residence in the United States, and an other-focused locus of control are significantly associated with increased HIV risk. Women who have been in the United States for relatively longer periods of time may be more likely to integrate U.S. sexual norms into their own behavior and may, as a consequence, be at higher risk of HIV infection. Increased HIV prevention efforts must be made available to Mexican and Puerto Rican women born outside of the United States. These prevention efforts must necessarily focus not only on HIV prevention strategies, but also on the dynamics within male-female intimate relations. Increased attention to younger Puerto Rican and Mexican women is also needed.

Foreign-born women and, in particular, Hispanic foreign-born women, are less likely to have insurance, are less likely to have insurance that covers prenatal care, and are less likely to utilize prenatal care compared with US-born Hispanic women. Significant concern has been raised regarding the ability of immigrant women to access prenatal care services because of severe restrictions imposed on immigrants' eligibility for Medicaid-funded services following the passage in 1996 of the federal Personal Responsibility and Work Opportunity Reform Act (PRWORA) and the Illegal Immigration Reform and Immigrant Responsibility Act (IIRAIRA). We conducted an interview-based study of prenatal care utilization with women of Mexican ethnicity and diverse immigration statuses in San Diego County, California. Our findings indicate that, despite increased levels of fear associated with recent immigration and with undocumented status, there were no statistically significant differences across immigration statuses in length of time to receipt of medical care for gynecological events and for prenatal care.
