Objectives: To compare suicide rates observed in Brazil after the onset of the COVID-19 pandemic with the estimated rate based on suicide deaths between 2010 and 2020, and identify sociodemographic variables associated with this outcome. Methods: Ecological time-series study. Data were obtained from Brazilian Unified Health System Department of Information Technology (DATASUS), with the structural break of the data set in March 2020. The number of actual suicides observed and the number of expected suicides if there were no COVID-19 pandemic were analyzed through bayesian structural time series modeling. Results: The overall incidence of suicides in Brazil remained stable after the start of the COVID-19 pandemic compared to what would be expected. However, there was a significant increase in suicide deaths among women (6.9%) and older adult (9.1%). Analysis by macro-regions of the country showed significant increases in suicide deaths in the Center-West (7.4%), Northeast (5.7%), and Southeast (10%). Stratified analyses revealed differences according to age, sex, education, and skin color. Conclusions: Despite stability in the overall number of suicides, this phenomenon occurs heterogeneously among different population groups and regions of Brazil. Rates have increased in populations with a history of poor access to health, which may have been more severely impacted by the pandemic.

Objective: To compare the prevalence and subtypes of childhood maltreatment (CM) between individuals with and without substance use disorder (SUD) and investigate the influence of different traumas on the preferential use of substances and the severity of dependence. Methods: The sample consisted of 1,040 men with SUD (alcohol users [n=315], crack-cocaine users [n=406], multiple-substance users [n=319]) and 201 controls. The Childhood Trauma Questionnaire (CTQ) and the Addiction Severity Index-6 (ASI-6) were used to assess CM and drug-use patterns. Results: Individuals with SUD had a higher prevalence of CM than controls (63.4 vs. 28.1%, respectively). Exposure to physical trauma was associated with alcohol use disorder and severity of alcohol use. In contrast, emotional trauma was associated with use of multiple substances and severity of drug use in crack-cocaine users. Conclusions: This study corroborates the association of CM with SUD susceptibility. Our results suggest that the type of CM may influence preferential substance use and addiction severity. In this sense, physical traumas are more associated with alcohol use, while emotional and sexual traumas favor use of multiple drugs, especially crack cocaine. These findings may help the development of tailored prevention and intervention strategies.

Resumo Objetivo Analisar os efeitos da pandemia de COVID-19 sobre o consumo de equipamentos e produtos de proteção individual (EPPI), assim como a frequência de infecção de sítio cirúrgico (ISC) em pacientes não infectadas por COVID-19 submetidas a cesarianas. Métodos Foi realizado umestudo retrospectivo em umamaternidade de um hospital público de ensino que não fazia parte do serviço de referência para o tratamento do COVID-19. Foram comparados o consumo de EPPI e a ocorrência de ISC após cesárea nos períodos mensais antes e após a ocorrência do primeiro caso de COVID-19 em Porto Alegre, RS, Brasil. O consumo de EPPI foimedido emunidades demáscaras, luvas, aventais e gorros, e o uso de produtos à base de álcool ou de sabonete para higienização das mãos em ml/paciente/dia. O índice SSI foi calculado como a proporção de casos de ISC sobre o número de cesarianas realizadas mensalmente durante o período do estudo. Resultados Houve aumento em todos os itens medidos do EPPI, com o consumo de máscaras descartáveis apresentando uma mediana de 1.450 no período pré-COVID e de 2550 no período pós-COVID (aumento de 75,9%). Detectou-se também diminuição de ISC, com medianas de 1,74 no período pré-COVID e de 0,89 no período pós-COVID, com redução de 49% no valor da mediana. Conclusão O aumento do consumo de EPPI pode ser resultado de práticas mais seguras adotadas pelos profissionais de saúde com o advento do COVID-19, do qual a redução na ocorrência de ISC pode ser uma consequência direta. Apesar da gravidade da crise, pode-se afirmar que situações extremas podem gerar reflexões valiosas e oportunidades de melhorias.

Abstract Objective To analyze effects of the COVID-19 pandemic on the consumption of personal protective equipment and products (PPEP), as well as the frequency of surgical site infection (SSI) among non-COVID-19 patients submitted to cesarean sections. Methods A retrospective study was conducted in a maternity unity of a public teaching hospital which was not part of the reference service for COVID-19 treatment. It compared PPEP consumption and the occurrence of SSI after cesarean sections in monthly periods before and after the occurrence of the first case of COVID-19 in Porto Alegre, state of Rio Grande do Sul, Brazil. Personal protective equipment and products consumption was measured as units of masks, gloves, gowns, and caps, and use of alcohol-based products or soap for hand sanitation asml/patient/day. The SSI index was calculated as the proportion of cases of SSI over the number of cesarean sections performed monthly during the study period. Results There was an increase in all measured items of PPEP, with consumption of disposable masks with a median of 1,450 units in the pre-COVID period, and of 2550 in the post-COVID period (a 75.9% increase). A decrease of 49% in SSI was detected, with a median of 1.74 in the pre-COVID period and of 0.89 in the post-COVID period. Conclusion The increase in consumption of PPEP could be a result of safer practices adopted by healthcare workers with the advent of COVID-19, of which the following reduction in the occurrence of SSI could be a direct consequence. Despite the severity of the crisis, one could state that extreme situations can lead to valuable reflections and opportunities for improvement.

Resumo Objetivo Analisar a prescrição de antimicrobianos para gestantes admitidas no serviço de obstetrícia que apresentaram pielonefrite aguda. Métodos Foram realizados três estudos transversais comparando a prescrição de antimicrobianos para pielonefrite em gestantes nos períodos avaliados (2010-2011: 99 indivíduos avaliados; 2013: 116 indivíduos avaliados; 2015: 107 indivíduos avaliados), no Hospital Fêmina, Porto Alegre, RS, Brasil. A análise foi realizada antes e após a promoção de um protocolo institucional para o tratamento da pielonefrite durante a gravidez e, em uma terceira ocasião, após a introdução de uma ferramenta educacional móvel para uso por smartphone. Resultados A avaliação das prescrições médicas e a adequação das prescrições entre os diferentes períodos estudados revelaram um aumento significativo na conduta adequada para a escolha do antimicrobiano (2010: 83,8%; 2013: 95,7%; e 2015: 100%), via de administração (2010: 97%; 2013: 100%; e 2015: 100%) e intervalo (2010: 91,9%; 2013: 95,7%; e 2015: 100%), após a introdução do protocolo, e novamente após a implementação do aplicativo com orientações sobre tratamento antimicrobiano. Conclusão O uso de aplicativos móveis específicos deve ser incentivado para obter melhor qualidade e precisão nas prescrições e incluir estratégias que não apenas reduzam o risco de resultados negativos, mas que também melhorem a qualidade dos cuidados e do tratamento para manter a saúde conjunta da mãe e do bebê.

Abstract Objective To analyze the prescription of antimicrobial agents for pregnant women admitted into the obstetrics service who presented with acute pyelonephritis. Methods Three cross-sectional studies were performed comparing the prescription of antimicrobials for pyelonephritis in pregnant women in the time periods evaluated (2010-2011: 99 patients evaluated; 2013: 116 patients evaluated; 2015: 107 patients evaluated), at the Hospital Fêmina, Porto Alegre, in the state of Rio Grande do Sul, Brazil. The analysis was performed before and after the promotion of an institutional protocol for the treatment of pyelonephritis during pregnancy, and on a third occasion after the introduction of a smartphone-based mobile educational tool. Results The evaluation of the prescribing physicians and the adequacy of the prescriptions between the different periods studied revealed a significant increase in appropriate conduct for the choice of antimicrobial (2010: 83.8%; 2013: 95.7%; and 2015: 100%), route of administration (2010: 97%; 2013: 100%; and 2015: 100%), and interval (2010: 91.9%; 2013: 95.7%; and 2015: 100%), following the introduction of the protocol, and again after the implementation of the softwareapplicationwithorientationsontheantimicrobial treatment. Conclusion The use of specific mobile applications should be encouraged to attain a better quality and accuracy in prescriptions and to include strategies that not only reduce the risk of negative outcomes, but also improve the quality of care and treatment for maintaining the health both of the mother and of the baby.

Objective: Many studies correlate characteristics of family functioning and the development of drug addiction. This study sought to evaluate and compare the family environment styles of two groups of psychoactive substance users: 1) alcohol-only users and 2) crack-cocaine users. Methods: Three hundred and sixty-four users of alcohol, crack-cocaine, and other drugs, recruited from research centers in four Brazilian capitals participated in this study. Subjects were evaluated through the Family Environment Scale and the Addiction Severity Index, 6th version (ASI-6). ASI-6 t-scores were compared by analysis of variance (ANOVA) and post-hoc tests. A final model was obtained using a logistic regression analysis. All analyses were adjusted for partner, age, and psychiatric t-score. Results: We found a significant difference between groups in the cohesion subscale (p = 0.044). The post-hoc test revealed a difference of 1.06 points (95%CI 0.11-2.01) between groups 1 (6.45±0.28) and 2 (5.38±0.20). No significant between-group differences were observed in the other subscales. However, categorical analyses of variables regarding family dynamic showed that crack users more often reported that sometimes people in their family hit each other (30.4% vs. 13.2%, p = 0.007) and that people in their family frequently compared each other regarding work and/or school achievement (57.2% vs. 42.6%, p = 0.041). Conclusion: These results suggest that families of crack-cocaine users are less cohesive than families of alcohol users. This type of family environment may affect treatment outcome, and should thus be adequately approached.

RESUMO Objetivos Poucos estudos brasileiros correlacionam transtornos de personalidade (TP) com transtorno por uso de substâncias (TUS). O objetivo deste estudo é verificar a associação entre eles, avaliar a frequência dos TP na população de dependentes químicos internados, correlacionar com características sociodemográficas, drogas de escolha, frequência de recaída, aderência a grupos de autoajuda e psicoterapia em até seis meses após a alta hospitalar. Métodos Uma amostra de 101 pacientes internados em dois hospitais foi selecionada. Os seguintes instrumentos foram aplicados: um questionário para identificação de características sociodemográficas e padrão de uso de drogas, algumas questões da sexta versão do ASI-6 (Addiction Severity Index), o SCID-II e algumas questões específicas sobre participação em grupos de autoajuda e em psicoterapia, bem como o uso de medicações. Resultados Destes 101 pacientes, 55,4% foram diagnosticados com TP, sendo evitativa (14,9%), limítrofe (11,9%) e antissocial (8,9%) as mais frequentemente encontradas. Pacientes com TP demonstraram ter feito uso mais precoce de crack na vida (p = 0,038) e também tinham mais tratamentos anteriores do que aqueles sem TP (p = 0,005). Pacientes com TP limítrofe estavam menos preocupados com o problema de abuso de substâncias (p = 0,003). Após seis meses de seguimento, nenhuma diferença estatística significativa foi encontrada entre pacientes com e sem TP acerca do uso de drogas ou aderência ao tratamento. Conclusão Uma alta prevalência de TP foi encontrada em pacientes internados por TUS. Pacientes diagnosticados com TP e TUS necessitam a identificação da comorbidade e das características de sua personalidade, a fim de planejar um tratamento mais abrangente e eficaz.

ABSTRACT Objectives A few Brazilian researches correlate personality disorders (PD) and substance related disorders (SRD). The aim of the present study is to investigate the association between them, to evaluate the PD frequency among chemical dependents inpatients, this comorbidity association with social and demographic characteristics, used drug of choice, its impact on clinical evolution until the moment of their committal, the frequency of relapse, self-help group – and psychotherapic adherence among SRD patients six months following committal. Methods A 101 inpatients sample of chemical dependents was enrolled in 2 hospitals. The following instruments were applied: a questionnaire for social and demographic characteristics identification and drug use pattern, some questions from the sixth version of the Addiction Severity Index (ASI-6), the SCID-II questionnaire and specific questions concerning psychotherapic and self-help groups participation, and medication use. Results From these 101 patients, 55.4% were diagnosed with PD, being avoidant (14.9%), borderline (11.9%) and antisocial (8.9%) the more frequent ones found. PD patients had an earlier crack use in life (p = 0.038) and had also more previous treatments than the ones without PD (p = 0.005). Borderline PD patients were less worried to substance use problem (p = 0.003). After 6-months follow-up, no statistical significance was found between patients with and without PD regarding drug use or treatment adherence. Conclusion A high PD diagnosis was found in drug use inpatients. Patients diagnosed with SRD and PD need the identification of this comorbidity and of their personality characteristics in order to plan a more comprehensive and effective treatment.

RESUMO Racional: Não há consenso sobre o tamanho ideal das alças intestinais no bypass gástrico em Y-de-Roux em cirurgias bariátricas. Objetivo: Avaliar os desfechos metabólicos de pacientes submetidos ao bypass gástrico com alça intestinal alimentar e biliopancreática de tamanhos diferentes. Métodos: Realizou-se coorte retrospectiva em pacientes obesos (IMC≥35 kg/m2) diabéticos com síndrome metabólica submetidos ao bypass gástrico em Y-de-Roux. Foram divididos em três grupos conforme a dimensão das alças intestinais: grupo 1, alça biliopancreática de 50 cm e alça alimentar de 100 cm; grupo 2, alça biliopancreática de 50 cm e alça alimentar de 150 cm e grupo 3, alça biliopancreática de 100 cm e alça alimentar de 150 cm. Foram avaliados os parâmetros que compõem a síndrome metabólica. Resultados: Incluíram-se 63 pacientes, com média de idade de 44.7±9.4 anos. Todos eram diabéticos, 62 (98.4%) hipertensos e 51 (82.2%) dislipidêmicos. Os três grupos eram homogêneos em relação às variáveis estudadas. Em 24 meses houve remissão da hipertensão arterial sistêmica em 65% do grupo 1, 62.5% no grupo 2 e 68.4% no grupo 3. A remissão do diabete melito tipo 2 ocorreu em 85% dos pacientes do grupo 1, 83% no grupo 2, e 84% no grupo 3. Não houve diferença estatística na porcentagem de perda do excesso de peso entre os grupos e as medidas da cintura abdominal reduziram de forma homogênea em todos os grupos. A dimensão das alças também não influenciou na melhora da dislipidemia. Conclusão: A variação da dimensão das alças intestinais não influenciou na melhora da síndrome metabólica neste grupo de pacientes.

ABSTRACT Background: There is no consensus on the ideal size of intestinal loops in gastric bypass of bariatric surgeries. Aim: To evaluate the metabolic outcome of patients submitted to gastric bypass with alimentary and biliopancreatic loops of different sizes. Methods: Was conducted a retrospective cohort study in diabetic obese patients (BMI≥35 kg/m2) with metabolic syndrome submitted to gastric bypass. The patients were divided into three groups according to the size of the intestinal loop: group 1, biliopancreatic limb 50 cm length and alimentary limb 100 cm length; group 2 , biliopancreatic limb 50 cm length and alimentary limb 150 cm length; and group 3, biliopancreatic limb 100 cm length and alimentary limb 150 cm length. The effect of gastric bypass with different sizes of intestinal loops in relation to the parameters that define metabolic syndrome was determined. Results: Sixty-three patients were evaluated, and they had a mean age of 44.7±9.4 years. All were diabetics, with 62 (98.4%) being hypertensive and 51 (82.2%) dyslipidemic. The three groups were homogeneous in relation to the variables. In 24 months, there was a remission of systemic arterial hypertension in 65% of patients in group 1, 62.5% in group 2 and 68.4% in group 3. Remission of diabetes occurred in 85% of patients in group 1, 83% in group 2 and 84% in group 3. There was no statistical difference in %LEW between the groups, and waist measurements decreased in a homogeneous way in all groups. The size of loops also had no influence on the improvement in dyslipidemia. Conclusion: Variation in size of intestinal loops does not appear to influence improvement in metabolic syndrome in this group of patients.

Dirigir sob a influência de álcool/drogas (DUI) contribui para ocorrência de acidentes de trânsito, sendo que homens e mulheres diferem quanto ao seu consumo. Objetivo: Analisar as diferenças no consumo de álcool/drogas e nos comportamentos de risco para dirigir entre homens e mulheres. Método: Estudo transversal, com amostra consecutiva de 609 vítimas de acidentes de trânsito atendidas nas emergências de Porto Alegre. Realizou-se entrevista estruturada, teste de bafômetro e saliva para screening de álcool e drogas. Resultados: As mulheres acidentaram-se principalmente como passageiras e pedestres, (p < 0.001). Não houve diferença na triagem para abuso/dependência ou alcoolemia positiva. Porém, os homens referiram mais "beber pesado" e utilizaram mais THC e cocaína, enquanto as mulheres utilizaram benzodiazepínicos (p < 0.05). Conclusão: Este é o primeiro estudo brasileiro a comparar uso de álcool e drogas entre homens e mulheres vítimas de acidentes de trânsito. Os dados podem ser úteis na elaboração de estratégias específicas de prevenção que considerem as diferenças de gênero.

Driving under the influence of alcohol/ drugs (DUI) is a well-established risk factor for traffic accidents, and men and women have different consumption patterns. The scope of this paper is to analyze differences in alcohol and drug consumption, as well as on behavior associated with traffic accidents among men and women. A cross-sectional study was conducted with 609 sequential traffic accident victims attended in emergency care from Porto Alegre. Subjects gave a structured interview, were breathalyzed and had a saliva test for alcohol/drug screening. Results showed that women were mainly passengers or pedestrians (p < 0.001). There was no significant difference in positive blood alcohol concentration. However, men reported more binge drinking and THC use, while women had more benzodiazepine in their saliva (p<0.05). This is the first Brazilian study to compare alcohol and drug use among men and women who were the victims of traffic accidents. Results point to differences in the pattern of substance abuse, as well on risk behavior. Data may be useful for specific prevention strategies that take gender differences into consideration.

OBJECTIVES:To evaluate family problems among crack/cocaine users compared with alcohol and other substance users.METHODS:A cross-sectional multi-center study selected 741 current adult substance users from outpatient and inpatient Brazilian specialized clinics. Subjects were evaluated with the sixth version of the Addiction Severity Index, and 293 crack users were compared with 126 cocaine snorters and 322 alcohol and other drug users.RESULTS:Cocaine users showed more family problems when compared with other drug users, with no significant difference between routes of administration. These problems included arguing (crack 66.5%, powder cocaine 63.3%, other drugs 50.3%, p= 0.004), having trouble getting along with partners (61.5%×64.6%×48.7%, p= 0.013), and the need for additional childcare services in order to attend treatment (13.3%×10.3%×5.1%, p= 0.002). Additionally, the majority of crack/cocaine users had spent time with relatives in the last month (84.6%×86.5%×76.6%, p= 0.011).CONCLUSIONS:Brazilian treatment programs should enhance family treatment strategies, and childcare services need to be included.

OBJETIVO: Avaliar diferenças e similaridades em relação a beber e dirigir (DUI) nas cinco macroregiões brasileiras. MÉTODO: Um roadside survey foi realizado nas 27 capitais brasileiras. Foram selecionados aleatoriamente 3.398 condutores que responderam a uma entrevista estruturada e foram testados com uso de etilômetro. Para a construção de modelos preditivos de alcoolemia positiva (BAC), as regiões foram agrupadas de acordo com sua similaridade, obtida por MANOVA, em: 1) Norte e Nordeste; 2) Sul e Centro-Oeste; 3) Sudeste. Em cada grupo foi realizado um modelo de regressão robusta para estimar as variáveis associadas a BAC. RESULTADOS: Dentre os condutores, 2.410 ingeriram bebidas alcoólicas nos 12 meses anteriores, sendo a maioria composta por homens com idade mediana de 36 anos. A única variável associada a BAC em todos os grupos foi ter lazer como motivo da viagem. Baixa escolaridade, idade > 30 anos, dirigir carros/motos e ter realizado teste de bafômetro previamente foram associadas a BAC em ao menos dois grupos. CONCLUSÕES: Os fatores associados a DUI foram semelhantes nas regiões, especialmente o motivo da viagem e a escolaridade, embora algumas especificidades regionais tenham sido observadas. Estas informações são estratégicas para políticas públicas destinadas a redução do DUI.

OBJECTIVE: To evaluate regional differences and similarities associated with drinking and driving (DUI) in the five Brazilian macro-regions. METHOD: A roadside survey was conducted in the 27 Brazilian state capitals. A total of 3,398 drivers were randomly selected and given a structured interview and a breathalyzer test. To determine the predictors of positive blood alcohol concentration (BAC) in each region, a MANOVA was performed, and 3 groups were used as follows: 1) North and Northeast, 2) South and Midwest, and 3) Southeast. A Poisson robust regression model was performed to assess the variables associated with positive BAC in each group. RESULTS: Of all surveyed drivers, 2,410 had consumed alcohol in the previous 12 months. Most were male, with a median age of 36. Leisure as the reason for travel was associated with positive BAC in all 3 groups. Low schooling, being older than 30, driving cars or motorcycles and having been given a breathalyzer test at least once in their lives predicted DUI in at least two different groups. CONCLUSIONS: Factors , especially low schooling and leisure as a reason for travel, associated with drinking and driving were similar among regions, although certain region-specific features were observed. This information is important for aiming to reduce DUI in the country.

INTRODUÇÃO: Este estudo transversal avaliou a prevalência de transtornos psiquiátricos e a associação entre dirigir alcoolizado e transtornos psiquiátricos entre motoristas por meio de entrevistas telefônicas. MÉTODO: Motoristas (n = 1.134) selecionados a partir de um estudo realizado nas rodovias de 25 capitais brasileiras foram etilometrizados e tiveram sua saliva testada para substâncias psicoativas. Uma entrevista por telefone foi realizada para obter dados sobre transtornos psiquiátricos através do MINI. A associação entre transtornos psiquiátricos e dirigir com uso recente de substâncias foi analisada com um modelo de regressão de Poisson. RESULTADOS: A prevalência de transtornos psiquiátricos foi de 40,5% entre os motoristas que beberam/usaram drogas, em comparação com 12,9% nos demais motoristas. Motoristas que dirigiram com uso recente de substâncias relataram uma maior prevalência de depressão (19,4%), mania (6,5%), hipomania (5,4%), transtorno de estresse póstraumático (8,6%), personalidade antissocial (7,8%), e abuso ou dependência de álcool/drogas (48,1%) quando comparados com os outros motoristas (3,5%, 2,5%, 2,1%, 0,5%, 1,3% e 18,3%, p < 0,001), respectivamente). Motoristas com uso recente de substâncias apresentaram 2,5 mais chance de ter qualquer diagnóstico psiquiátrico (IC: 1,8-3,6, p < 0,001). DISCUSSÃO: Este é o primeiro estudo em países de baixa e média renda cujo objetivo é avaliar transtornos psiquiátricos em motoristas com uso recente de substâncias por meio de entrevistas telefônicas. Transtornos psiquiátricos foram associados com o comportamento de dirigir com uso recente de substâncias. Este tipo de informação epidemiológica é fundamental para estratégias de planejamento que visam enfrentar problemas relacionados com o beber e dirigir, uma vez que estas condições psiquiátricas são diagnosticáveis. OBSERVAÇÕES FINAIS: Os resultados deste estudo podem auxiliar no desenvolvimento de intervenÇÕes, programas de tratamento e avaliação psiquiátrica, tanto no Brasil quanto no exterior.

INTRODUCTION: This cross-sectional study assessed the prevalence of psychiatric disorders among drivers , as well as the association between recent alcohol and drug use and psychiatric diagnoses using telephone interviews. METHODS: Drivers (n = 1,134) included in a roadside survey from 25 Brazilian state capitals were given a breathalyzer test, and their saliva was tested for psychoactive drugs. A telephone interview was conducted to perform psychiatric disorder evaluations using the MINI. This association was analyzed with a Poisson regression model. RESULTS: The prevalence of any psychiatric disorder was 40.5% among drivers with recent alcohol or drug use, compared with 12.9% among the other drivers. Alcohol/drug-positive drivers reported a higher prevalence of depression (19.4%), mania (6.5%), hypomania (5.4%), post-traumatic stress disorder (8.6%), antisocial personality (7.8%), and substance/alcohol abuse or dependence (48.1%) compared with other drivers (3.5, 2.5, 2.1, 0.5, 1.3 and 18.3% [p < 0.001], respectively). Drivers with recent alcohol or drug use were 2.5 times more likely to have a psychiatric diagnosis (CI: 1.8-3.6, p < 0.001). DISCUSSION: This is the first study in a low-/middle-income country to evaluate psychiatric disorders in drivers with recent alcohol or drug using telephone interviews. Psychiatric disorders were found to be associated with drug and alcohol use. This type of epidemiological information for curtailing related driving problems, as these psychiatric conditions are diagnosable. FINAL REMARKS: The results of this study can aid in the design of interventions, treatment programs and focused psychiatric evaluations, both in Brazil and abroad.

OBJETIVO: Verificar a frequência de alcoolemia positiva entre os motoristas e examinar fatores associados em um estudo transversal nas capitais brasileiras. MÉTODOS: 3.398 motoristas foram abordados em rodovias que atravessam todas as 27 capitais brasileiras nos horários entre 12:00 e 00:00 (sextas e sábados). Eles realizaram o teste do etilômetro e foram coletados dados sobre suas características de condução e consumo de álcool. Para avaliar os fatores associados, foi realizada uma regressão logística multivariável seguindo um quadro conceitual hierárquico. RESULTADOS: A prevalência de alcoolemia positiva (> 0,1 mg/L) foi de 4,2%. A regressão logística múltipla mostrou que educação (até 8 anos de estudo: OR = 2,0; IC 95%: 1,4-3,0), idade (> 30 anos: OR = 2,6; IC 95%: 1,8-3,8), tipo de veículo (dirigir um carro: OR = 3,0; IC 95%: 1,7-5,1; conduzir uma motocicleta: OR = 3,7; IC 95%: 2,1-6,4), consumo excessivo de álcool (OR = 1,7; IC 95%: 1,3-2,4), ter realizado o teste do etilômetro anteriormente (OR = 2,6; IC 95%: 1,8-3,7), e a finalidade da viagem (retorno de uma festa: OR = 1,9; IC 95%:1,3-3,0; viagem de lazer: OR = 1,7; IC 95%: 1,3-2,4; e estar dirigindo após as 20 horas: OR = 1,7; IC 95%: 1,3-2,3) foram independentemente associados com o dirigir sob influência de álcool. CONCLUSÃO: Os resultados sugerem que fatores ambientais externos selecionados, tais como características socioeconômicas e demográficas, bem como características pessoais, como o consumo de álcool e comportamento em relação a beber e dirigir, foram associados com alcoolemia positiva entre os motoristas brasileiros. Os resultados podem ajudar a orientar políticas em relação a beber e dirigir e abordagens preventivas.

OBJECTIVE: To verify the frequency of positive Blood Alcohol Concentration (BAC) among drivers and to examine associated factors in a cross-sectional study of Brazilian state capitals. METHODS: 3,398 drivers were approached on highways crossing all 27 Brazilian capitals from 12 p.m. to 12 a.m. (Fridays and Saturdays). They were breathalyzed and data on their driving characteristics and alcohol consumption were collected. Multivariate logistic regression following a hierarchical conceptual framework was used to evaluate associated factors. RESULTS: The overall weighted prevalence of positive BAC (> 0.1 mg/L) was 4.2%. The multivariate analysis showed that education up to 8 years (OR = 2.0; 95% CI: 1.4-3.0), age > 30 years (OR = 2.6; 95% CI: 1.8-3.8), type of vehicle (cars: OR = 3.0; 95% CI: 1.7-5.1; motorcycles: OR = 3.7; 95% CI: 2.1-6.4), binge drinking (OR = 1.7; 95% CI: 1.3-2.4), having been breathalyzed before (OR = 2.6; 95% CI: 1.8-3.7), and purpose of the trip (coming from a party: OR = 1.9; 95% CI: 1.3-3.0; leisure trip: OR = 1.7; 95% CI: 1.32.4; driving after 8 p.m.: OR = 1.7; 95% CI: 1.3-2.3) were independently associated with DUI. CONCLUSION: Study findings suggest that selected external environmental factors, such as socioeconomic and demographic characteristics as well as personal characteristics like alcohol consumption and the relationship between drinking and driving were associated with positive BAC among Brazilian drivers. Results can help to inform drinking and driving policy and preventive approaches.
