Resumo: Os homens são o principal grupo afetado pela infecção do HIV no Brasil, com tendência de crescimento nos últimos dez anos. Nos dados oficiais, os homens heterossexuais representam 49% dos casos, os homossexuais 38% e os bissexuais 9,1%. Os homens heterossexuais ficaram subsumidos na categoria de “população geral”, não recebendo destaque em políticas ou ações de prevenção. O presente artigo se propõe a analisar as circunstâncias e estratégias por meio das quais os homens heterossexuais descobrem o diagnóstico do HIV. Busca-se, assim, compreender os caminhos percorridos, bem como os atores sociais envolvidos no diagnóstico de HIV/aids. Os dados analisados resultam de uma pesquisa qualitativa na qual foram entrevistados 36 homens vivendo com HIV/aids que não se identificam como homossexuais e/ou bissexuais. Esses homens foram contatados em três serviços especializados em aids de Porto Alegre, Rio Grande do Sul, Brasil. Os resultados indicam que eles se consideram imunes ao HIV, sendo o diagnóstico um evento inesperado. As mulheres (parceiras afetivo-sexuais e/ou ex-parceiras) são peças fundamentais para o diagnóstico masculino, pois revelam, seja pelo pré-natal, seja pelo adoecimento, a presença do HIV. Uma parcela importante dos homens se descobre soropositivo por ocasião de alguma doença, como a tuberculose, ou após várias idas e vindas dos serviços de saúde. A busca pela testagem de forma espontânea só acontece mediante a identificação de situações e sinais associados a uma possível contaminação. Os homens heterossexuais possuem poucas oportunidades de diagnóstico do HIV e, para além do gênero, são sujeitos à vulnerabilidade programática.

Introduction: Influenza morbidity and mortality are significant in the countries of South America, yet influenza vaccination is as low as 56.7% among pregnant women, reaching 76.7% of adults with chronic diseases. This article measures the relative values for the vaccination hesitancy indicators of confidence, complacency and convenience by risk-groups in urban areas of five countries of South America with contrasting vaccination rates, analyzing their association with sociodemographic variables and self-reported immunization status. Methods: An exit survey was applied to 640 individuals per country in Brazil, Chile, Paraguay, Peru and Uruguay, distributed equally across risk groups of older adults, adults with risk factors, children ≤6 and pregnant women. Indicators were constructed for vaccine confidence, complacency and convenience. Analysis of variance and multiple logistic analysis was undertaken. Results: Adults with risk factors are somewhat more confident of the influenza vaccine yet also more complacent. Convenience is higher for mothers of minors. Children and older adults report higher levels of vaccination. The 3Cs are more different across countries than across risk groups, with values for Chile higher for confidence and those for Uruguay the lowest. Complacency is lower in Brazil and higher in Uruguay. Results suggest that confidence and complacency affect vaccination rates across risk groups and countries. Conclusions: Influenza vaccine confidence, complacency and convenience have to be bolstered to improve effective coverage across all risk groups in the urban areas of the countries studied. The role played by country contextual and national vaccination programs has to be further researched in relation to effective coverage of influenza vaccine.

O uso de preservativos pelos jovens aumentou, o que não significa que sejam utilizados em todas as relações sexuais; além disso, seu uso varia durante a trajetória afetivo-sexual. Estudou-se a prevalência e fatores associados ao uso de preservativo na iniciação sexual e na última relação sexual, para moças e rapazes de 18-24 anos. Os dados são da Pesquisa GRAVAD, um estudo transversal com amostra probabilística estratificada, através de entrevistas domiciliares, em três capitais brasileiras. Na análise, utilizou-se regressão logística multinomial seguindo modelo hierarquizado. A prevalência de uso de preservativo na iniciação, dentre os usuários de métodos contraceptivos, foi 80,7% pelas moças e 88,6% pelos rapazes. Este uso cai para 38,8% e 56%, respectivamente, na última relação. Nos dois eventos, o uso de preservativo esteve associado, para ambos os sexos, ao pertencimento social e à idade da iniciação. A utilização do preservativo na iniciação determina o uso na última relação (OR = 2,42 para os rapazes e 1,89 para as moças). O maior uso de preservativo entre os jovens não implica uso continuado. As moças utilizaram menos preservativo, comparadas aos rapazes, nos eventos estudados.

Introduction: High level of HIV/AIDS knowledge is required for an effective adoption of preventive strategies. Objective: To assess HIV/AIDS knowledge among men who have sex with men (MSM) in 12 Brazilian cities. Methods: Respondent-Driven Sampling method was used for recruitment. HIV/AIDS knowledge was assessed by Item Response Theory. Difficulty and discrimination parameters were estimated, and the knowledge score was categorized in three levels: high, medium, and low. Logistic regression was used for analysis. Results: Among 4,176 MSM, the proportion of high level of knowledge was 23.7%. The following variables were positively associated with high knowledge (p < 0.05): age 25+ years old, 12+ years of schooling, white skin color, having health insurance, having suffered discrimination due to sexual orientation, having had a syphilis test, and having received educational material in the previous 12 months. Exchanging sex for money was negatively associated. Conclusions: The proportion of only 23.7% of high HIV/AIDS knowledge was low. We should note that the only potential source of knowledge acquisition associated with high level of knowledge was receiving educational materials. Our study indicates the need for expansion of public prevention policies focused on MSM and with more effective communication strategies, including the development of knowledge that involves motivation and abilities for a safer behavior.

Introduction: This paper details the methods used in the second national Biological and Behavioral Surveillance Survey (BBSS) of HIV, syphilis, and hepatitis B and C among men who have sex with men in Brazil. Methods: Respondent-driven sampling (RDS) was used in 12 cities in 2016. The targeted sample size was initiated with five to six seeds in each city. HIV, syphilis, and Hepatitis B and C rapid tests were offered to participants. RDS Analyst with Gile’s successive sampling (SS) estimator was used to adjust results as recommended and a weight for each individual was generated for further analysis. Data for the 12 cities were merged and analyzed using Stata 14.0 complex survey data tools with each city treated as its own stratum. Results: Duration of data collection varied from 5.9 to 17.6 weeks. 4,176 men were recruited in the 12 cities. Two sites failed to achieve targeted sample size due to a six-month delay in local IRB approval. No city failed to reach convergence in our major outcome variable (HIV). Conclusion: The comprehensive BBSS was completed as planned and on budget. The description of methods here is more detailed than usual, due to new diagnostic tools and requirements of the new STROBE-RDS guidelines.
