Exploring the Masculine Identity in the Context of HIV Prevention in Chile.

PURPOSE: This study aims to describe human immunodeficiency virus (HIV)-related knowledge and beliefs, as well as understanding attitudes towards masculinity in the context of HIV prevention, held among Chilean men. DESIGN: This study reports the qualitative findings of a sequential qualitative-quantitative mixed methodology study: Bringing men into HIV Prevention in Chile, NIH R01 TW007674-03. METHODS: Twenty in-depth interviews using a qualitative, descriptive approach to elicit information for the study were conducted among men residing in two communities of low socio-economic status in Santiago, Chile. FINDINGS: Content analysis of interviews revealed three main themes regarding machismo and how it relates to HIV: sexuality and machismo, the changing nature of machismo, and violence against women. CONCLUSIONS: Addressing HIV and intimate partner violence through developing education programs tailored to meet the needs of Chilean men are needed to include men in HIV prevention efforts. CLINICAL RELEVANCE: Specifically, incorporating ideas of what men consider healthy masculinity and working to destigmatize men who have sex with men are important steps in addressing the negative aspects of machismo.

Pilot testing an internet-based STI and HIV prevention intervention with Chilean women.

PURPOSE: The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. DESIGN: This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI's preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. FINDINGS: After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. CONCLUSIONS: The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. CLINICAL RELEVANCE: The study provided important information about the ability of an Internet-based intervention to reduce young women's risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective.

Oral rapid test: an alternative to traditional HIV screening in Chile.

OBJECTIVE: To compare the sensitivity and specificity of an Oral Rapid Test (ORT) to that of the Enzyme-Linked Immunosorbent Assay (ELISA) for HIV testing in Santiago, Chile; to track the number of study participants returning for ELISA testing results; and to analyze the participants' perceptions of the ORT compared to the ELISA. METHODS: A total of 497 people were recruited in Santiago, Chile: 153 had previously tested positive for HIV, and 344 were of unknown status. Participants were tested for HIV using both the ELISA and the ORT to examine and compare specificity and sensitivity. Qualitative data were collected from 22 participants to compare perceptions of the testing experience with ORT versus ELISA. RESULTS: The ELISA reported 184 (37%) of the 497 participants as being "positive" for HIV antibodies; the ORT showed 181 (36.4%) as being "reactive" for HIV. The ORT showed a sensitivity of 98.4% (95.7%-99.9%, 95% Confidence Interval) and specificity of 100%. The Kappa test produced K = 0.983 (P < 0.0001). Of the 344 participants whose HIV status was unknown at the start of the study, 55 failed to return for their ELISA results. Participants positively perceived ORT as having reduced both waiting time and anxiety over obtaining their test results. ORT oral swabbing appeared more practical and less invasive than drawing blood for the ELISA. CONCLUSIONS: The ORT and ELISA were statistically equal in specificity and sensitivity. ORT provides quicker results, potentially ensuring that more people receive them, and does not require handling of or exposure to potentially hazardous blood products.

Factores que Influencian la Adquisición de Infecciones de Transmisión Sexual y VIH en Mujeres Jóvenes Chilenas que Participaron en la Intervención Online I-STIPI (Factors That Influence the Acquisition of Sexually Transmitted Infections and HIV in Chilean Young Women Who Participated in the Online Intervention I-STIPI).

The aim of this descriptive cross-sectional study was to investigate the following factors associated with sexually transmitted infections and human immunodeficiency virus prevention: (a) knowledge, (b) attitudes, (c) self-efficacy, (d) vulnerability, (e) risky behaviors, (f) preventive behaviors, and (g) internet use among 40 Chilean women between 18 and 24 years who participated in the pilot of an Internet based STI/HIV prevention intervention (I-STIPI). A structured questionnaire available in a secure website was used for data collection and it included questions related to STI and HIV prevention. The results of the study indicated that young women are at risk of acquiring STIs and HIV and have special needs for prevention. Familiarity and frequency of use of internet in this population can be used for STIs and HIV prevention.

[CARETAKERS OF CHILDREN LIVING WITH HIV, THEIR KNOWLEDGE AND SELF-EFFICACY]. / CUIDADORES DE NIÑOS QUE VIVEN CON VIH, SUS CONOCIMIENTOS Y AUTOEFICACIA.

Worldwide, the number of children 15 years and under living with HIV has increased from 1.6 million in 2001 to 2 million in 2007. The care of these children is demanding. The challenges related to this care are even more when it is delivered in homes where not the workers have training in the area. The was conducted to understand the level of knowledge and self-efficacy related to HIV communication among the workers in a home for children and families living with HIV. A cross sectional, descriptive study was conducted. The average age of participants was 39.37(±11.97) years, close to 50% had low levels of general HIV knowledge and HIV prevention knowledge. In relation to self-efficacy, the majority (61.9%) did not feel confident speaking about this topic with the children. These results demonstrate the need for training for people working with children who live with HIV, both in terms of content and communication abilities and the need to generate a continuous training program that assures the delivery of quality care.

OBJETIVO: Comparar la sensibilidad y la especificidad de una prueba oral rápida con las del análisis de inmunoadsorción enzimática (ELISA) para la detección del VIH en Santiago de Chile, Chile; hacer un seguimiento del número de participantes en el estudio que regresan para saber los resultados del ELISA; y analizar las percepciones de los participantes con relación a la prueba oral rápida en comparación con el ELISA. MÉTODOS: Se incluyeron 497 personas en Santiago de Chile: 153 tenían resultados positivos para el VIH, y la situación de las restantes 344 era desconocida. Se sometió a los participantes a pruebas de detección del VIH tanto mediante el ELISA como mediante la prueba oral rápida, con objeto de analizar y comparar la especificidad y la sensibilidad. Se recopilaron datos cualitativos de 22 participantes para comparar sus impresiones con relación a la experiencia de someterse a la prueba oral rápida en comparación con el ELISA. RESULTADOS: Mediante el ELISA se notificó que 184 de los 497 participantes (37%) obtuvieron un resultado "positivo" en las pruebas de detección de anticuerpos contra el VIH; mediante la prueba oral rápida 181 participantes (36,4%) fueron "reactivos" para el VIH. Esta prueba demostró una sensibilidad de 98,4% (intervalo de confianza de 95%: 95,7-99,9%) y una especificidad de 100%. El coeficiente kappa (K) fue de 0,983 (P < 0,0001). De los 344 participantes cuyo estado con respecto a la infección por el VIH era desconocido al comienzo del estudio, 55 no regresaron para conocer los resultados del ELISA. Los participantes percibieron positivamente la prueba oral rápida debido al período de espera más breve y la reducción de la ansiedad por conocer los resultados de la prueba. La obtención de una muestra oral mediante hisopo resultó más práctica y menos invasora que la extracción de sangre necesaria para llevar a cabo un ELISA. CONCLUSIONES: La prueba oral rápida y el ELISA se mostraron estadísticamente equivalentes en cuanto a especificidad y sensibilidad. La primera proporciona resultados más rápidos, garantiza que más personas puedan conocerlos, y no requiere el manejo o la exposición a hemoderivados potencialmente peligrosos.
