A potential syndemic effect associated with symptoms of depression among men who have sex with men.

INTRODUCTION: Globally, depression rates are high among men who have sex with men (MSM). Multiple factors may interact synergistically to increase this risk. This analysis assessed the prevalence of symptoms of depression among MSM in Brazil and synergistic effects of several factors. METHODS: Cross-sectional study conducted in 12 cities using respondent-driven sampling. Sociodemographic and behavioral characteristics were collected. The PHQ-9 was used to screen for depression. Having moderate-severe depressive symptoms was compared to none-mild using logistic regression. The syndemic factor was a composite of hazardous alcohol use, sexual violence, and discrimination due to sexual orientation. Those with one to three of these factors were compared to those with none. RESULTS: The weighted prevalence of moderate-severe depressive symptoms was 24.9% (95%CI = 21.8-28.8) and 16.2%, 22.9%, 46.0% and 51.0% when none, one, two, or three syndemic factors were present, respectively, indicating a dose-response effect. Perception of HIV risk, high level of HIV knowledge, known HIV infection, and health self-rated as poor or very poor were also associated with depressive symptoms. CONCLUSION: The prevalence of moderate-severe depressive symptoms among MSM in Brazil is high, and selected factors act synergistically in increasing their prevalence. Public health policies should consider holistic depression prevention and treatment interventions for this population.

Cause-specific mortality for 249 causes in Brazil and states during 1990-2015: a systematic analysis for the global burden of disease study 2015.

BACKGROUND: Reliable data on cause of death (COD) are fundamental for planning and resource allocation priorities. We used GBD 2015 estimates to examine levels and trends for the leading causes of death in Brazil from 1990 to 2015. METHODS: We describe the main analytical approaches focused on both overall and specific causes of death for Brazil and Brazilian states. RESULTS: There was an overall improvement in life expectancy at birth from 1990 to 2015, but with important heterogeneity among states. Reduced mortality due to diarrhea, lower respiratory infections, and other infectious diseases contributed the most for increasing life expectancy in most states from the North and Northeast regions. Reduced mortality due to cardiovascular diseases was the highest contributor in the South, Southeast, and Center West regions. However, among men, intentional injuries reduced life expectancy in 17 out of 27 states. Although age-standardized rates due to ischemic heart disease (IHD) and cerebrovascular disease declined over time, these remained the leading CODs in the country and states. In contrast, leading causes of premature mortality changed substantially - e.g., diarrheal diseases moved from 1st to 13th and then the 36th position in 1990, 2005, and 2015, respectively, while violence moved from 7th to 1st and to 2nd. Overall, the total age-standardized years of life lost (YLL) rate was reduced from 1990 to 2015, bringing the burden of premature deaths closer to expected rates given the country's Socio-demographic Index (SDI). In 1990, IHD, stroke, diarrhea, neonatal preterm birth complications, road injury, and violence had ratios higher than the expected, while in 2015 only violence was higher, overall and in all states, according to the SDI. CONCLUSIONS: A widespread reduction of mortality levels occurred in Brazil from 1990 to 2015, particularly among children under 5 years old. Major shifts in mortality rates took place among communicable, maternal, neonatal, and nutritional disorders. The mortality profile has shifted to older ages with increases in non-communicable diseases as well as premature deaths due to violence. Policymakers should address health interventions accordingly.

Sexual Violence Against Men Who Have Sex with Men in Brazil: A Respondent-Driven Sampling Survey.

We estimated the prevalence of sexual violence (SV) experience among men who have sex with men (MSM) in Brazil and identified its associated risk factors. We recruited 3859 MSM through respondent driven sampling. A multivariable hierarchical analysis was performed using an ecological model. The prevalence of having ever experienced SV was 15.9 % (95 % confidence interval [CI] 14.7-17.1). SV experience was independently associated with discrimination due to sexual orientation (odds ratio [OR] 3.05; 95 % CI 2.10-4.42), prior HIV testing (OR 1.81; 95 % CI 1.25-2.63), ≤14 years at first sex (OR 1.86; 95 % CI 1.28-2.71), first sex with a man (OR 1.89; 95 % CI 1.28-2.79), presenting STI symptoms (last year) (OR 1.66; 95 % CI 1.12-2.47), and having suicidal ideas (last 6 months) (OR 2.08; 95 % CI 1.30-3.35). The high levels of SV against MSM in Brazil place them at a markedly higher risk of SV than the general population. Homophobic prejudice is the strongest determinant of SV and urgently needs to be included at the forefront of the national response to SV.

HIV sexual risk behavior among emerging adults in psychiatric treatment in Brazil.

HIV infection among young populations is increasing worldwide. Adolescents in mental health treatment have demonstrated higher rates of HIV risk behavior than their peers. This first risk behavior study of youth in psychiatric treatment in Brazil reports findings from a cross-sectional national sample of emerging adult psychiatric patients (18-25 years old). The prevalence of lifetime unprotected sex was 65.9%. Multiple logistic regression indicated that being married/in union; sex under the influence of alcohol/drugs; physical violence; earlier sexual debut; and depressive/substance use disorders were associated with unsafe sex. Interventions and services that address these risks during this critical developmental window are urgently needed.

Correlates of HIV infection among patients with mental illness in Brazil.

People living with mental illness are at increased risk for HIV. There are scarce data on correlates and prevalence of HIV infection, and none with a nationally representative sample. We report on correlates of HIV infection from a cross-sectional national sample of adults receiving care in 26 publicly funded mental health treatment settings throughout Brazil. Weighted prevalence rate ratios were obtained using multiple log-binomial regression modeling. History of homelessness, ever having an STD, early age of first sexual intercourse before 18 years old, having suffered sexual violence, previous HIV testing, self-perception of high risk of HIV infection and not knowing one's risk were statistically associated with HIV infection. Our study found an elevated HIV seroprevalence and correlates of infection were not found to include psychiatric diagnoses or hospitalizations but instead reflected marginalized living circumstances and HIV testing history. These adverse life circumstances (history of homelessness, having suffered sexual violence, reporting a sexually transmitted disease, and early sexual debut) may not be unique to people living with mental illness but nonetheless the mental health care system can serve as an important point of entry for HIV prevention in this population.

Temporal trends and molecular epidemiology of HIV type 1 infection in Rio de Janeiro, Brazil.

HIV-1 molecular epidemiology studies carried out in Rio de Janeiro, Brazil have identified the prevalence of subtypes B, F1 and BF1 recombinants. A high percentage of HIV-1 subtype B isolates in Rio de Janeiro harbor the GWG motif at the V3 tip (B'' variant) instead of the canonical GPG motif (B variant). To trace the dynamics of the HIV-1 variants over time in different exposure categories in Rio de Janeiro, the HIV-1 proviral DNA from heterosexual men (HET) and men who have sex with men (MSM) from two distinct time periods (1990-1992 and 2008-2010) were extracted, and the env-gp120 region was amplified. Neighbor-joining phylogenetic analysis was performed to determine the viral subtype, and Bayesian analysis was used to trace the HIV-1 transmission networks. A predominance of subtype B was observed in both study periods, independent of the exposure risk category. An increase of non-B subtypes was observed in the HET group, but these subtypes were maintained among the MSM group. The distribution of HIV-1 subtype B signatures in the first and second periods studied were, respectively, HET (GPG) [44.8-51.5%], (GWG) [13.8-33.3%], and (GXG) [41.4-15.2%] and MSM (GPG) [34-50%], (GWG) [55.3-30.6%], and (GXG) [10.7-19.4%]. In the first period, an association between GWG and MSM was verified while a significant reduction of this association was observed during the second period. The phylogenetic tree and the BaTS program detected the clustering of isolates only according to the B signatures but not by exposure risk category. Our findings indicate a stable prevalence of HIV-1 subtypes B and F over time in Rio de Janeiro and further suggest that the B'' subclade of subtype B was possibly introduced into the MSM group in this area of Brazil.

HIV among MSM in a large middle-income country.

OBJECTIVE: To conduct the first national biological and behavioral surveillance survey for HIV among MSM in Brazil. DESIGN: A cross-sectional surveillance study utilizing Respondent Driven Sampling (RDS) in 10 cities, following formative research. Planned sample: 350 MSM reporting sex with another man in the last 12 months, at least 18 years of age, and residing in the city of the study. METHODS: Conventional RDS recruitment. Results were calculated for each city using RDSAT 5.6. For the national estimate, a new individual weight using a novel method was calculated. The 10 cities were aggregated, treated as strata and analyzed using STATA11.0. Self-reported HIV status and logistic regression was used to impute missing values for serostatus, an important issue for RDSAT. RESULTS: A total of 3859 MSM were interviewed. Sample was diverse, most self-identified as mulatto or black, were social class C or below, and had relatively low levels of education. More than 80% reported more than one partner in the last 6 months. Only 49% had ever tested for HIV. HIV prevalence among MSM ranged from 5.2 to 23.7% in the 10 cities (3.7-16.5% without imputation) and was 14.2% for all cities combined with imputation. The overall prevalence was two and three times higher than that estimated for female sex workers and drug users, respectively, in Brazil. Half of those who tested HIV positive were not aware of their infection. CONCLUSION: The AIDS epidemic in Brazil is disproportionately concentrated among MSM, as has been found in other countries. Renewed efforts to encourage testing, prevention and treatment are required.

Lack of utility of risk score and gynecological examination for screening for sexually transmitted infections in sexually active adolescents.

BACKGROUND: Sexually transmitted infections constitute the main health risk among adolescents. In developing countries the diagnosis and treatment of cervical infections is based on the syndromic approach. In this study we estimated the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae among female adolescents from a Health Sector of the city of Goiânia, Brazil, and validated cervicitis diagnosis using World Health Organization/Ministry of Health risk score and gynecological examination. METHODS: A cross-sectional community-based sample of 914 15- to 19-year-old female teenagers was randomly selected and referred to the local Family Health Program. Of these, 472 (51.6%) were sexually active and gynecological examinations were carried out for 427. Endocervical samples were collected to perform the polymerase chain reaction for C. trachomatis and N. gonorrhoeae. Performance of risk score, the presence of mucopurulent discharge, friability, ectopia and pain during cervical maneuver were compared with the presence of C. trachomatis or N. gonorrhoeae or both. RESULTS: The prevalence of C. trachomatis and N. gonorrhoeae was 14.5% and 2.1%, respectively. The risk score had a specificity of 31.9% (95% confidence interval, 21.2 to 44.2) and a positive predictive value of 20.8% (95% confidence interval, 13.5 to 29.7). Friability was the component of the gynecological examination that presented the best performance with a sensitivity of 43.5%, specificity of 81.0%, and 30.6% of positive predictive value. CONCLUSION: The prevalence of infection by C. trachomatis and N. gonorrhoeae was high among these sexually active adolescents. The syndromic approach is clearly inadequate for screening and treating these infections in this population. Therefore, the implantation of other strategies to control these infections among adolescents is urgently required.

The influence of HCV coinfection on clinical, immunological and virological responses to HAART in HIV-patients.

The potential impact of the hepatitis C virus (HCV) on clinical, immunological and virological responses to initial highly active antiretroviral therapy (HAART) of patients infected with human immunodeficiency virus (HIV) is important to evaluate due to the high prevalence of HIV-HCV coinfection. A historical cohort study was conducted among 824 HIV-infected patients starting HAART at a public referral service in Belo Horizonte, Brazil, to assess the impact of HCV seropositivity on appearance of a new AIDS-defining opportunistic illness, AIDS-related death, suppression of viral load, and an increase in CD4-cell count. A total of 76 patients (9.2%) had a positive HCV test, 26 of whom (34.2%) had a history of intravenous drug use. In multivariate analysis, HCV seropositivity was associated with a smaller CD4-cell recovery (RH=0.68; 95% CI [0.49-0.92], but not with progression to a new AIDS-defining opportunistic illness or to AIDS-related death (RH=1.08; 95% CI [0.66-1.77]), nor to suppression of HIV-1 viral load (RH=0.81; 95% CI [0.56-1.17]) after starting HAART. These results indicate that although associated with a blunted CD4-cell recovery, HCV coinfection did not affect the morbidity or mortality related to AIDS or the virological response to initial HAART.

[Patient's understanding of information on antiretroviral therapy: an application of the latent trait model]. / Compreensão da terapia anti-retroviral: uma aplicação de modelo de traço latente.

The aim of this study was to develop a score to determine the level of understanding regarding information on antiretroviral therapy (ART) among patients initiating treatment. This was a cross-sectional analysis based on interviews with HIV patients in outpatient public referral centers (Belo Horizonte, Minas Gerais State, Brazil). The score for patients' understanding of their medicines was obtained using a latent trait model, estimated by the Item Response Theory, based on the concordance between each patient answer and the written prescription. Hierarchical linear regression was used to assess patients' global understanding of ART, considering each class of drugs (level 1) and the individual (level 2). Among 406 patients, 37.9% failed to reach a minimum level of understanding of their treatment. The item with the highest level of difficulty was "precaution in use". The item "dosage" showed the most varied understanding of ART. A high proportion of patients displayed minimal understanding of ART, indicating a high potential risk for non-adherence to therapy. It is thus necessary to identify factors associated with insufficient understanding of ART.

Compreensão da terapia anti-retroviral: uma aplicação de modelo de traço latente / Patient's understanding of information on antiretroviral therapy: an application of the latent trait model

O objetivo do estudo foi desenvolver um escore para determinar o nível de compreensão de informações sobre terapia anti-retroviral (TARV) em pacientes no início do tratamento. Estudo transversal baseado em entrevistas com pacientes infectados pelo HIV em serviços públicos de referência (Belo Horizonte, Minas Gerais, Brasil). O escore da compreensão dos medicamentos foi obtido utilizando-se modelo de traço latente estimado pela Teoria de Resposta ao Item, após análise de concordância entre a resposta do paciente e a informação contida na prescrição. Realizou-se análise de regressão linear hierárquica para obter a compreensão global dos medicamentos, considerando cada classe de medicamentos (nível 1) e o individuo (nível 2). Dos 406 pacientes avaliados, 37,9 por cento não atingiram um nível mínimo de compreensão do tratamento. O item com maior nível de dificuldade foi precaução de uso. O item dose foi o que mais diferenciou os pacientes quanto à compreensão da TARV. Observou-se alta proporção de pacientes com nível mínimo de compreensão da TARV, o que pode indicar um alto risco potencial de não-adesão à terapia. É necessário identificar fatores associados com este baixo nível de compreensão.

Behavior surveillance: prevalence and factors associated with high-risk sexual behavior among HIV-infected men in Brazil in the post-HAART era.

A cross-sectional analysis was conducted to describe unsafe sexual practices among HIV-infected men under care in two Brazilian urban areas. Data were collected by face-to-face interviews. Twenty-five percent practiced unprotected sex in the previous year, 16% were abstinent, 33% had sex with men only, 45% with women only, 48% had male/female stable partners, 84% were on HAART and 48% had AIDS. Illicit drug use, number of female partners, having stable partners, and STD diagnosis were associated with unsafe sex. Interventions to reduce risk taking behavior among HIV-positive men under care in these settings are urgent, especially among heterosexual stable couples.

Non-adherence among patients initiating antiretroviral therapy: a challenge for health professionals in Brazil.

OBJECTIVE: To assess the incidence, magnitude and factors associated with the first episode of non-adherence for 12 months after the first antiretroviral prescription. DESIGN: A prospective study of HIV-infected patients receiving their first antiretroviral prescription in public referral centers, Belo Horizonte, Brazil. Baseline assessment occurred at the moment of the first prescription and follow-up visits at the first, fourth and seventh month, from May 2001 to May 2003. METHODS: Non-adherence was self-reported and defined as the intake of less than 95% of the prescribed doses for 3 days before the follow-up interviews. Cumulative and person-time incidence were estimated and Cox's proportional model was used to assess the relative hazard (RH) of non-adherence with 95% confidence interval for both univariate and multivariate analysis. RESULTS: Among 306 patients, the cumulative incidence of non-adherence was 36.9% (incidence rate 0.21/100 person-days). Multivariate analysis (P < 0.05) showed that unemployment (RH = 2.17), alcohol use (RH = 2.27), self-report of three or more adverse reactions (RH = 1.64), number of pills per day (RH = 2.04), switch in antiretroviral regimen (RH = 2.72), and a longer time between the HIV test result and the first antiretroviral prescription (RH = 2.27) were associated with an increased risk of non-adherence, whereas the use of more than one health service indicated a negative association (RH = 0.54). CONCLUSION: The current analysis has pointed out the importance of clinical and health service characteristics as potential indicators of non-adherence after initiating therapy. Early assessment and intervention strategies should be priorities in these AIDS public referral centres. Feasible and reliable indicators for the routine monitoring of adherence should be incorporated in clinical practice.

[Syphilis positivity in puerperal women: still a challenge in Brazil]. / Positividade para sífilis em puérperas: ainda um desafio para o Brasil.

OBJECTIVE: To investigate the factors associated with positive syphilis serology results in puerperal women who were receiving care at 24 health centers accredited by Brazil's National Program on Sexually Transmitted Diseases and AIDS. METHODS: This cross-sectional study included a probabilistic random sample of 3047 puerperal women. The eligibility criterion was being admitted for delivery or curettage in the selected centers. After an interview to collect demographic and clinical information, a blood sample was taken and then examined with the Venereal Disease Research Laboratory (VDRL) slide test. With positive VDRL results, the fluorescent treponemal antibody-absorption test (FTA-Abs) was used for confirmation. The event considered for analysis was positivity on the VDRL test, with confirmation by the FTA-Abs. For the statistical analysis, odds ratios and 95% confidence intervals were calculated. The model fit was assessed using the Hosmer-Lemeshow test. RESULTS: The prevalence of syphilis among the women studied was 1.7%. Multivariate analysis showed that increased risk for positive VDRL and FTA-Abs results was associated with the following characteristics: family income below one minimum wage, age < 17 years at first sexual intercourse, age < or = 14 years at first pregnancy, history of syphilis or of other sexually transmitted diseases prior to the current pregnancy, treatment for syphilis during the current pregnancy, partner having been tested for syphilis, having a positive HIV test result or having no HIV test result on record, previous preterm delivery, and stillbirth as an outcome of pregnancy. Only 43% of the women had had six or more prenatal visits, and only 3% had had one VDRL test during the first trimester of pregnancy and another VDRL test during the third trimester, as is recommended by Brazil's national Ministry of Health. CONCLUSIONS: This study shows that the problem of congenital syphilis is far from being solved in Brazil. It is necessary to provide adolescents with family planning services as well as guidance on sexual issues, to improve prenatal follow-up, and to research the history of sexually transmitted diseases in both the pregnant woman and her sexual partner.

[HIV patients' understanding of information on antiretroviral therapy]. / Compreensão de informações relativas ao tratamento anti-retroviral entre indivíduos infectados pelo HIV.

To assess the understanding of information related to antiretroviral therapy among HIV-infected patients enrolled in public AIDS services (Belo Horizonte, Minas Gerais State, Brazil), a cross-sectional analysis was carried out, based on interviews with patients after initial provision of antiretroviral drugs. The study evaluated the information on antiretroviral therapy provided by healthcare professionals and the patients' level of understanding in relation to prescription information. This level was classified as insufficient if there was disagreement of more than 30.0% between the information reported by the patient and the written prescription. Divergence between prescriptions and information reported by 358 interviewed patients was observed. The level of understanding regarding the prescribed antiretroviral was obtained, and 26.3% of patients displayed insufficient understanding. The results show an important proportion of patients with misunderstanding of information regarding antiretroviral therapy, mainly those with limited schooling and low income. It is necessary to bolster strategies to increase quality of recommendations provided to these patients. Improving the multidisciplinary team approach to patient care should help reverse the observed situation.

Compreensão de informações relativas ao tratamento anti-retroviral entre indivíduos infectados pelo HIV / HIV patients' understanding of information on antiretroviral therapy

Para avaliar a compreensão das informações sobre a terapia anti-retroviral entre portadores do HIV/AIDS atendidos em serviços públicos de referência, em Belo Horizonte, Minas Gerais, Brasil, foi realizada análise transversal por meio de entrevistas com pacientes, após a primeira dispensação de anti-retrovirais. A orientação recebida dos profissionais de saúde e o nível de compreensão pelo paciente foram investigados, sendo este classificado como insuficiente se houvesse discordância igual ou superior a 30,0 por cento entre a resposta do paciente e a informação contida na prescrição para itens selecionados. Divergências entre as informações da prescrição e as relatadas pelos 358 pacientes foram observadas. O nível de compreensão das informações sobre anti-retrovirais prescritos foi classificado como insuficiente para 26,3 por cento. Os resultados obtidos revelam proporção importante de pacientes com lacunas na compreensão de informações sobre a terapêutica anti-retroviral combinada. É necessário implementar estratégias para aumentar a qualidade das orientações fornecidas a esses pacientes. O enfoque multidisciplinar no atendimento aos pacientes poderá contribuir para reverter a situação observada.
