RESUMO

Resumo O objetivo do artigo é estimar a prevalência de transtornos relacionados ao uso de álcool (TRA) e fatores associados entre indivíduos da população brasileira que reportaram doenças crônicas não-transmissíveis (DCNT), transtornos mentais (TM) e doenças infeciosas (DI). Análise secundária do III Levantamento Nacional sobre o Uso de Drogas pela População Brasileira, cujo desfecho principal foi a presença de TRA. A prevalência de TRA foi estimada para três subgrupos: indivíduos que reportaram DCNT, TM e DI. Os fatores associados a TRA dentro de cada grupo foram analisados utilizando modelos de regressão logística. Dos 15.645 adultos entrevistados, 30,5% (IC95%: 29,4-31,5) reportaram DCNT, 17,6% (IC95%: 16,5-18,7) TM e 1,6% (IC95%: 1,2-1,9) DI. Considerando as comorbidades, a amostra analítica foi de 6.612. Não foi encontrada diferença estatisticamente significativa na prevalência de TRA entre indivíduos com DCNT (7,5% [IC95% 6,1-8,7]), TM (8,4% [IC95% 6,7-10,2]) e DI (12,4% [IC95% 7,0-17,8]). Os principais fatores associados a TRA, em todos os grupos, foram ser do sexo masculino e jovem. Considerando a alta prevalência de TRA em todos os grupos é necessário seu rastreio sistemático em serviços de saúde que atendam DCNT, TM e DI.

Abstract The study aimed to estimate the prevalence of alcohol use disorder (AUD) and associated factors in Brazilian adults that reported chronic noncommunicable diseases (NCDs), mental disorders (MDs), and infectious diseases (IDs). This was a secondary analysis of the 3rd National Survey on Drug Use by the Brazilian Population in which the principal outcome was presence of AUD. Prevalence of AUD was estimated for three subgroups: individuals that reported NCDs, MDs, and IDs. Factors associated with AUD in each group were analyzed using logistic regression models. Of the 15,645 adults interviewed, 30.5% (95%CI: 29.4-31.5) reported NCDs, 17.6% (95%CI: 16.5-18.7) MDs, and 1.6% (95%CI: 1.2-1.9) IDs. Considering comorbidities, the analytical sample was 6,612. No statistically significant difference was found in the prevalence of AUD between individuals with NCDs (7.5% [95%CI: 6.1- 8.7]), MDs (8.4% [95%CI: 6.7-10.2]), and IDs (12.4% [95%CI: 7.0-17.8]). The main factors associated with AUD in all the groups were male sex and young adult age. Considering the high prevalence of AUD in all the groups, systematic screening of AUD is necessary in health services that treat NCDs, MDs, and IDs.

RESUMO

ABSTRACT Objective To estimate the prevalence of concomitant substance consumption and analyze associated risk factors in a non-probabilistic sample of the Brazilian population of transgender women and travestis. Methods A cross-sectional study was conducted with recruitment via respondent-driven sampling. The sample included transgender women and travestis residing in São Paulo, Porto Alegre, Salvador, Manaus, and Campo Grande, aged 18 years or older, between 2019 and 2021. The outcome was the concomitant use of licit and illicit substances. The association between sociodemographic/behavioral factors and the outcome was analyzed through Poisson regression with mixed effects. Adjusted prevalence ratios (confidence interval of 95% — 95%CI) were estimated. Results The prevalence in the last 12 months of multiple substance use was 49.3%, of which 65.5% were alcohol, 52.9% tobacco, and 40.1% marijuana. Transgender women and travestis who use multiple substances face more violence (1.71; 95%CI 1.14-2.55), unemployment (1.58; 95%CI 1.05-2.37) and pervasive unstable work status (1.52; 95%CI 1.08-2.14), transactional sex (1.51; 95%CI 1.21-1.88) which can be their sole option to make a living, and are aged 18 to 24 years (1.37; 95%CI 1.14-1.65). Conclusion The use of multiple substances may be an attempt to cope with distress and marginalization. Substance use has been associated with multiple harms and medical conditions. Comprehensive management and care should be provided, as defined by the key principles of the Brazilian Unified Health System. Health care should be integrated into structural interventions.

RESUMO Objetivo Estimar a prevalência do consumo concomitante de substâncias e analisar fatores de risco associados em uma amostra não probabilística da população brasileira de mulheres trans e travestis. Métodos Estudo transversal, com recrutamento por meio da metodologia respondent-driven sampling. A amostra incluiu mulheres trans e travestis residentes em São Paulo, Porto Alegre, Salvador, Manaus e Campo Grande, maiores de 18 anos, entre 2019 e 2021. O desfecho foi o uso concomitante de substâncias lícitas e ilícitas. A associação entre fatores sociodemográficos/comportamentais e o desfecho foi analisada com regressão de Poisson com efeitos mistos, estimando-se razões de prevalência ajustadas (intervalo de confiança de 95% - IC95%). Resultados A prevalência nos últimos 12 meses de uso de múltiplas substâncias foi de 49,3%, sendo 65,5% álcool, 52,9% tabaco e 40,1% maconha. Mulheres trans e travestis que usam múltiplas substâncias enfrentam mais violência (1,71; IC95% 1,14-2,55), desemprego (1,58; IC95% 1,05-2,37) e trabalho instável (1,52; IC95% 1,08-2,14), sexo transacional (1,51; IC95% 1,21-1,88), que pode ser a única opção de sustento, e têm de 18 a 24 anos (1,37; IC95% 1,14-1,65). Conclusão O uso de múltiplas substâncias pode ser uma tentativa de lidar com o sofrimento e a marginalização. O uso de substâncias tem sido associado a múltiplos danos e condições médicas. Uma gestão integral e cuidados abrangentes devem ser providenciados, conforme definido pelos princípios-chave do Sistema Único de Saúde do Brasil. Os cuidados de saúde devem ser integrados em intervenções estruturais.

RESUMO

ABSTRACT Objective The aim of this study was to investigate the prevalence of human immunodeficiency virus (HIV) infection among transgender women and travestis and to analyze factors associated with HIV infection in Brazil. Methods TransOdara was a cross-sectional study on sexually transmitted infections among transgender women and travestis in five Brazilian cities between 2019 and 2021. Self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling, completed an interviewer-led questionnaire, and provided samples to detect HIV. The outcome was the result of the rapid antigen testing for HIV. Adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI) were obtained using Poisson regression with robust variance. Results Overall, this population was found to be especially vulnerable, with high levels of unstable housing and engagement in informal work. They usually resort to transactional sex as their main working activity. Half of them earned less than the Brazilian minimum wage, which characterizes a poor population living in dire conditions. The overall HIV prevalence was 34.40%. In the final model, the variables associated with the HIV prevalence were as follows: to be 31 years old or older, not studying at the moment they were interviewed, to be unemployed, and engaged in lifetime transactional sex. Conclusion We found disproportionately high HIV prevalence among transgender women and travestis, compared with a low prevalence among respective segments of Brazil's general population, which highlights the context of vulnerability in this population. The data point to the urgency for intensification and expansion of access to HIV prevention and strategies to stop discrimination in health care (among other services and contexts) and provide comprehensive services for this population.

RESUMO Objetivo Investigar a prevalência do vírus da imunodeficiência humana (HIV) entre mulheres trans e travestis em cinco capitais no Brasil. Métodos TransOdara foi um estudo de corte transversal que avaliou comportamentos e a prevalência de infecções sexualmente transmissíveis (IST) entre mulheres trans e travestis em cinco capitais brasileiras, entre 2019 e 2021. Mulheres trans e travestis ≥18 anos foram recrutadas utilizando respondent-driven sampling, responderam a um questionário e fizeram testes rápidos para HIV e outras IST. O desfecho foi o resultado do teste rápido para HIV. Estimaram-se razões de prevalência ajustadas e intervalos de confiança de 95% por meio da regressão de Poisson com variância robusta. Resultados: No seu conjunto, esta população mostrou-se vulnerabilizada, com níveis elevados de moradia instável e no mercado de trabalho informal. Habitualmente, essas mulheres recorrem ao sexo comercial como sua atividade profissional principal. Metade delas receberam menos do que um salário mínimo, vivendo em condições desfavoráveis. A prevalência da infecção pelo HIV foi de 34.40%. No modelo final, as variáveis associadas com a prevalência do HIV foram: ter 31 anos ou mais, não estar estudando no momento da entrevista, estar desempregada e estar engajada em sexo comercial. Conclusão Foi identificada uma prevalência substancialmente elevada para o HIV entre as mulheres trans e travestis (em contraste com a prevalência baixa na população geral de mulheres brasileiras), sublinhando o contexto de vulnerabilidade desta população. Os achados indicam claramente a premência de intensificar e expandir o acesso à prevenção do HIV e da implementação de estratégias que interrompam o processo de discriminação vivenciado nos serviços de saúde e ofereçam serviços apropriados a esta população.

RESUMO

RESUMO: Objetivou-se avaliar a segurança dos profissionais de saúde que atuaram no combate à pandemia de covid-19 em 2020 nos serviços de saúde brasileiros. Realizou-se inquérito on line, conduzido entre junho e setembro de 2020, com profissionais de saúde de instituições públicas e privadas brasileiras, com base no questionário Health workers exposure risk assessment and management in the context of COVID-19 virus, da Organização Mundial de Saúde, sendo analisados 2.832 registros. Raça/cor e categoria profissional foram variáveis relacionadas ao aumento de casos de covid-19 dentre os profissionais. Os que se autodeclararam não brancos, técnicos e auxiliares de enfermagem tiveram chance maior de resultado positivo, indicando maior suscetibilidade à infecção relacionada ao nível socioeconômico e/ou categoria profissional e papel desempenhado no cuidado ao paciente. As variáveis estrutura das unidades de saúde, localização, teste e disponibilidade de equipamentos de proteção individual relacionaram-se ao grau de risco de contrair a doença. Ressalta-se a importância da garantia de insumos e equipamentos aos profissionais de saúde, sobretudo em um contexto pandêmico e entre aqueles com baixo nível socioeconômico que atuam na linha de frente. Riscos em situações de emergência e escassez devem ser prospectivamente monitorados, ajustando-se às iniciativas no tocante à segurança do paciente.

ABSTRACT: The objective of this study was to evaluate the safety of health professionals who worked in the fight against the COVID-19 pandemic in 2020 in Brazilian health services. An online survey was conducted between June and September 2020, with health professionals from Brazilian public and private institutions, based on the Health workers exposure risk assessment and management in the context of COVID-19 virus, from the World Health Organization, and 2,832 records were analyzed. Race/color and professional category were variables related to the increase of covid-19 cases among professionals. Those who self-declared themselves non-white, technical and nursing assistants had a higher chance of positive results, indicating a higher susceptibility to infection related to socioeconomic level and/or professional category and a role played in patient care. The variables structure of the health units, location, test and availability of personal protective equipment were related to the degree of risk of contracting the disease. The importance of ensuring inputs and equipment to health professionals is highlighted, especially in a pandemic context and among those with low socioeconomic level who work on the front line. Risks in emergency and scarcity situations should be prospectively monitored, adjusting to patient safety initiatives.

RESUMEN: El objetivo de este estudio fue evaluar la seguridad de los profesionales de la salud que actuaron en la lucha contra la pandemia de COVID-19 en 2020 en los servicios de salud brasileños.

RESUMO

BACKGROUND: Agile, accessible and cheap diagnosis of hepatitis C virus (HCV) infection is essential to achieve the elimination of this infection, worldwide, as mandated by the World Health Organzation as part of its strategy for 2030. Dried blood spots (DBS) can be an attractive alternative for sample collection among people living in remote areas and vulnerable populations due to the less invasive collection, its biosafety, and storage & transportation of samples at room temperature. DESIGN: This study aims to estimate the usefulness of dried blood spot samples for the diagnosis and the assessment of HCV infection rates in three different settings in Brazil. Cross-sectional analysis of a sample collection from different populations, aiming to assess the performance of the testing algorithms and respective procedures among different populations with diverse background infection rates. METHODS: We reported the evaluation of DBS as alternative samples for detecting anti-HCV in different groups in real life conditions: (I) Vulnerable subjects living in remote areas of Southeast, North and Northeast Brazil (n = 1464); (II) Beauticians (n = 288); (III) People who use non-injectable drugs (n = 201); (IV) patients referred to outpatient care (n = 275). RESULTS: General assay accuracy was 99%, with a weighted kappa value of 0.9, showing an excellent performance. Sensitivities ranged from 87.5% to 100.0% between groups and specificities were above 99.2%. A total of 194 individuals had HCV RNA in serum and concordance of anti-HCV detection in DBS was 98.4%. CONCLUSIONS: DBS samples could be used for anti-HCV detection in different populations recruited in real life conditions and ambulatory settings, with a high overall sensitivity and specificity.

RESUMO

We compared sociodemographic characteristics, substance use patterns, sexual behavior, use of health services, and criminal records of homeless vs. domiciled users. Data are from the Brazilian National Survey on Crack Use. A discriminant model and correspondence analysis cross-compared characteristics of users according to their housing status. The logistic model revealed associations between "living in the streets" and female gender and intermittent work. "Homelessness" was also associated with the use of tobacco and "oxi" in the previous 30 days, reliance on soup kitchens, low access to public mental health services, and arrests in the previous year. Correspondence analysis highlighted the spatial proximity of the variables as follows: "having traded sex for drugs", "informal work", "age 31 years or older", "access to public mental health services", "problems with law enforcement", and female gender with homeless crack users. People who smoke crack cocaine in Northeast Brazil are seldom studied. Their profiles, stratified according to their housing conditions, show subgroups with specific characteristics. While domiciled users have access to specialized clinics, homeless users basically reported access to free food and harm reduction services.

Objetivou-se comparar características sociodemográficas, padrões de consumo de substâncias, comportamento sexual, utilização de serviços de saúde e envolvimento criminal de usuários, domiciliados e em situação de rua. Dados secundários do Inquérito Nacional sobre Uso do Crack, utilizando análise discriminante e de correspondência para comparar características dos usuários segundo condição de moradia. O modelo final de regressão logística evidenciou associações entre "situação de rua" e ser do sexo feminino, trabalho descontínuo, consumo de tabaco e "oxi" nos últimos 30 dias, uso de serviços de alimentação gratuita, baixo acesso a tratamento e frequentes detenções no último ano. Na análise de correspondência observou-se proximidade no espaço analítico de "troca de sexo por drogas", "trabalho informal", "idade" >31 anos, "baixo acesso a CAPS-ad", "problemas com a justiça criminal" e "sexo feminino" com os usuários de crack desabrigados. Pouco se sabe sobre usuários de crack em contexto na região Nordeste do Brasil. Os resultados evidenciam dois subgrupos com características específicas. Enquanto os domiciliados têm acesso aos serviços de CAPS-ad e outras clínicas especializadas, os usuários em situação de rua relataram, basicamente, acesso a serviços de alimentação gratuita e redução de danos.

RESUMO

Objectives: Previous studies have estimated the 30-day prevalence of alcohol use to be approximately 21% among youth in Brazil, despite the legal drinking age of 18 years. The present study aimed to determine the prevalence of underage drinking and its associated factors among adolescents in Brazil. Methods: The 3rd National Survey on Drug Use by the Brazilian Population (III Levantamento Nacional sobre o Uso de Drogas pela População Brasileira) is a nationwide, multi-stage, probability-sample household survey. Herein, youth between the ages of 12-17 years were included. Lifetime and 12-month alcohol use prevalence were estimated. Factors associated with 12-month alcohol use were evaluated through multivariate analysis considering survey weights and design. Results: Overall, 628 youth were interviewed. Estimated lifetime and 12-month alcohol use were 34.3% (standard error [SE] = 1.9) and 22.2% (SE = 1.7), respectively. Factors associated with 12-month drinking were: other/no religion vs. Christianity; living in rural vs. urban areas; self-reported diagnosis of depression vs. no self-reported depression; lifetime tobacco use vs. no history of tobacco use; and any illicit drug use vs. no history of illicit drug use. Conclusion: Considering that alcohol use is a major risk factor for early death among Brazilian youth, our findings highlight the importance of preventative measures to reduce underage drinking.

RESUMO

INTRODUCTION: Recent research has suggested an increase in the global prevalence of psychiatric symptoms during the COVID-19 pandemic. This study aimed to assess whether lifestyle behaviors can predict the presence of depression and anxiety in the Brazilian general population, using a model developed in Spain. METHODS: A web survey was conducted during April-May 2020, which included the Short Multidimensional Inventory Lifestyle Evaluation (SMILE) scale, assessing lifestyle behaviors during the COVID-19 pandemic. Depression and anxiety were examined using the PHQ-2 and the GAD-7, respectively. Elastic net, random forest, and gradient tree boosting were used to develop predictive models. Each technique used a subset of the Spanish sample to train the models, which were then tested internally (vs. the remainder of the Spanish sample) and externally (vs. the full Brazilian sample), evaluating their effectiveness. RESULTS: The study sample included 22,562 individuals (19,069 from Brazil, and 3,493 from Spain). The models developed performed similarly and were equally effective in predicting depression and anxiety in both tests, with internal test AUC-ROC values of 0.85 (depression) and 0.86 (anxiety), and external test AUC-ROC values of 0.85 (depression) and 0.84 (anxiety). Meaning of life was the strongest predictor of depression, while sleep quality was the strongest predictor of anxiety during the COVID-19 epidemic. CONCLUSIONS: Specific lifestyle behaviors during the early COVID-19 epidemic successfully predicted the presence of depression and anxiety in a large Brazilian sample using machine learning models developed on a Spanish sample. Targeted interventions focused on promoting healthier lifestyles are encouraged.

RESUMO

BACKGROUND AND AIMS: Active hepatitis C virus (HCV) infection is based on the detection of HCV RNA that it is effective but presents high cost and the need to hire trained personnel. This systematic review and meta-analysis is aimed at evaluating the diagnostic accuracy of HCV Ag testing to identify HCV cases and to monitor antiviral treatment including DAA treatment. METHODS: The studies were identified through a search in PubMed, Lilacs, and Scopus from 1990 through March 31, 2020. Cohort, cross-sectional, and randomized controlled trials were included. Two independent reviewers extracted data and assessed quality using an adapted Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Our primary outcome was to determine the accuracy of HCV Ag detection for the diagnosis, which we estimated using random-effects meta-analysis. RESULTS: Of 3,062 articles identified, 54 met our eligibility criteria. The studies described cohorts from 20 countries, including 14,286 individuals with chronic HCV individuals. Studies for ECLIA technology demonstrated highest quality compared to studies that used ELISA. The pooled sensitivity and specificity (95% CI) for HCV Ag detection of active HCV infection were 98.82% (95%CI = 98.04%; 99.30%) and 98.95% (95%CI = 97.84%; 99.49%), respectively. High concordance was found between HCV Ag testing and HCV RNA detection 89.7% and 95% to evaluate antiviral treatment. CONCLUSIONS: According to our findings, HCV Ag testing could be useful to identify HCV active cases in low-resource areas. For antiviral treatment, HCV Ag testing will be useful at the end of treatment.
