OBJECTIVES We evaluated the effectiveness of Hombres Sanos [Healthy Men] a social marketing campaign to increase condom use and HIV testing among heterosexually identified Latino men, especially among heterosexually identified Latino men who have sex with men and women (MSMW). METHODS Hombres Sanos was implemented in northern San Diego County, California, from June 2006 through December 2006. Every other month we conducted cross-sectional surveys with independent samples of heterosexually identified Latino men before (n = 626), during (n = 752), and after (n = 385) the campaign. Respondents were randomly selected from 12 targeted community venues to complete an anonymous, self-administered survey on sexual practices and testing for HIV and other sexually transmitted infections. About 5.6% of respondents (n = 98) were heterosexually identified Latino MSMW. RESULTS The intervention was associated with reduced rates of recent unprotected sex with both females and males among heterosexually identified Latino MSMW. The campaign was also associated with increases in perception of HIV risk, knowledge of testing locations, and condom carrying among heterosexual Latinos. CONCLUSIONS Social marketing represents a promising approach for abating HIV transmission among heterosexually identified Latinos, particularly for heterosexually identified Latino MSMW. Given the scarcity of evidence-based HIV prevention interventions for these populations, this prevention strategy warrants further investigation.

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two‐part study. In Study I, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3‐month follow‐up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6‐month follow‐up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psy‐chosocial correlates of HFV transmission. We discuss implications of these results.

This study examined the reach and impact of a social marketing intervention to reduce HIV risk among heterosexually identified (HI) Latino men who have sex with men and women (MSMW). Repeated cross-sectional intercept surveys were conducted in selected community venues during and after the campaign with 1,137 HI Latino men. Of them, 6% were classified as HI Latino MSMW. On average, 85.9% of the heterosexual respondents and 86.8% of the HI MSMW subsample reported exposure to the campaign. Responses to the campaign included having made an appointment for a male health exam that included HIV testing and using condoms. Campaign exposure was significantly associated with HIV testing behavior and intentions and with knowledge of where to get tested. The campaign reached its underserved target audience and stimulated preventive behaviors. Social marketing represents a promising approach for HIV prevention among HI Latinos, in general, and HI Latino MSMW, in particular.

OBJECTIVE This study examined the validity of child-reported exposure to secondhand smoke (SHS) and investigated factors, such as childs age, which might affect accuracy of recall. STUDY DESIGN AND SETTING Participants were drawn from a nonprobability sample of 380 families who completed baseline assessment as part of a randomized trial of an SHS reduction intervention conducted in an urban setting in Southern California. Parents and children (aged 8-13 years) retrospectively reported childs exposure to SHS using timeline followback methodology; reports were compared with childs urine cotinine. RESULTS Validity coefficients for parents and children were comparable (r=0.58 vs. r=0.53), but parents recalled three times more exposure than children (2.2 vs. 0.8 cigarettes per day; P<0.001). Regression models predicting cotinine indicated that including child in addition to parent reports resulted in better prediction than either alone. CONCLUSION When there is a choice, parent reports are preferable over child reports because of decreased underreporting. However, child-reported SHS exposure had adequate validity (r>0.50) and might be appropriate in some situations. Researchers might consider collecting both parent and child reports because each made a unique contribution to the prediction of cotinine.

Condom availability programs (CAPs) may increase access to condoms and contribute to increased condom use among youth. This study describes the characteristics, degree of satisfaction, and gender differences among users of a CAP implemented in two high schools in Tijuana (Baja California, Mexico). A kiosk distributing free male condoms was set up in two high schools in Tijuana. Kiosk users (N=570) were more likely to be male, young, and/or enrolled in a lower SES school. Most kiosk users were either sexually active or planning to have sex. Females were less likely to request condoms and to continue using the kiosk, but more likely to request information on other contraceptive methods. Results demonstrate the feasibility of implementing CAPs in Mexican schools and suggest that these programs can improve adolescents’ condom access.

Previous studies have suggested high rates of HIV infection and other sexually transmitted infections in theU.S.–Mexico border region. However, no information is available on the risk for HIV infection among Mexican adolescents living in this geographic area. This study examines the prevalence of HIV risk practices and psychosocial correlates among 370 high school students in the border city of Tijuana, Mexico, by gender and age group. The results indicate substantial risk for HIV infection among Tijuana youth due to unprotected sexual practices, lifetime rates of pregnancy and sexually transmitted infections, and needle-sharing practices, mostly related to tattooing and body piercing. These findings suggest the need for HIV prevention programs for Tijuana adolescents. These programs must be culturally sensitive and tailored to meet the needs of the different age and gender groups in this region.
