Amphetamine-type stimulant use and conditional paths of consumption: data from the Second Brazilian National Alcohol and Drugs Survey

Objective: The aim of this study was to estimate nationally representative prevalence rates of amphetamine-type stimulant (ATS) use and to identify consumption-associated factors, proposing a conditional model of direct and indirect consumption paths. Method: Using data from the Second Brazilian National Alcohol and Drugs Survey, this cross-sectional study analyzed a subsample of 3,828 participants between 15 and 64 years old, gathering information on the use of psychoactive substances in a probabilistic sample of the Brazilian household population. Results: Rates of lifetime and last-year ATS use were, respectively, 4.1 and 1.6%. Economically privileged individuals and users of other substances were more at risk for using ATS. The results suggest that higher education decreases the chances of ATS consumption. The conditional model showed that higher income increased ATS use, higher education lowered the odds of such an increase, and cocaine use cancelled that associative effect. Conclusion: Brazil presents high rates of ATS use. Prevention and treatment strategies should focus on the protective effect of higher education levels and should target polydrug use. Knowledge of ATS-associated factors and user profiles is the starting point for developing effective treatments and tailored prevention strategies.Conselho Nacional de Desenvolvimento Cientifico e TecnologicoCoordenacao de Aperfeicoamento de Pessoal de Nivel SuperiorInst Nacl Ciencia & Tecnol Polit Publ Alcool & Ou, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilPrevent Res Ctr, Oakland, CA USAUniv Fed Sao Paulo, UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilCNPqCAPESWeb of Scienc

Brazilian cross-cultural adaptation and validation of the List of Threatening Events Questionnaire (LTE-Q)

Objective: To perform a construct validation of the List of Threatening Events Questionnaire (LTE-Q), as well as convergence validation by identifying its association with drug use in a sample of the Brazilian population. Methods: This is a secondary analysis of the Second Brazilian National Alcohol and Drugs Survey (II BNADS), which used a cross-cultural adaptation of the LTE-Q in a probabilistic sample of 4,607 participants aged 14 years and older. Latent class analysis was used to validate the latent trait adversity (which considered the number of events from the list of 12 item in the LTE experienced by the respondent in the previous year) and logistic regression was performed to find its association with binge drinking and cocaine use. Results: The confirmatory factor analysis returned a chi-square of 108.341, weighted root mean square residual (WRMR) of 1.240, confirmatory fit indices (CFI) of 0.970, Tucker-Lewis index (TLI) of 0.962, and root mean square error approximation (RMSEA) score of 1.000. LTE-Q convergence validation showed that the adversity latent trait increased the chances of binge drinking by 1.31 time and doubled the chances of previous year cocaine use (adjusted by sociodemographic variables). Conclusion: The use of the LTE-Q in Brazil should be encouraged in different research fields, including large epidemiological surveys, as it is also appropriate when time and budget are limited. The LTE-Q can be a useful tool in the development of targeted and more efficient prevention strategies.Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Univ Fed Sao Paulo UNIFESP, Inst Nacl Pesquisa Alcool & Outras Drogas INCT IN, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Municipal Sao Caetano USCS, Escola Saude, Sao Caetano do Sul, SP, BrazilPacific Inst Res & Evaluat, Oakland, CA USAUniv Fed Sao Paulo UNIFESP, Inst Nacl Pesquisa Alcool & Outras Drogas INCT IN, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilWeb of Scienc

Use of licit and illicit substances among adolescents in Brazil - A national survey

Objective: We estimate the prevalence of alcohol, tobacco and illegal substance use in a national representative sample of adolescents. We also estimate how socio demographic characteristics, household environment and mental health are associated with substance misuse.Method: This is a cross-sectional study using data from the first Brazilian National Alcohol Survey, which gathered information on the use of psychoactive substances in 761 participants aged 14 to 19 years old. Weighted logistic regression was used to calculate adjusted odds ratios.Results: More than half of the adolescents interviewed were regular alcohol users and one out of ten were abusers and/or dependents. Older male adolescents living in urban areas were more likely to present alcohol related disorders and to smoke. Age had an inverse association with illegal substance use. Smokers and those using illegal substances were more likely to report domestic violence while those with alcohol abuse/dependence were more likely to have depression.Conclusions: the high prevalence of alcohol, tobacco and illicit substance consumption among Brazilian adolescents is staggering. Young males with mood disorders from urban areas are more at risk of developing alcohol disorders while illegal drug use is highly associated to household dysfunction in early life. Brazilian growing economy will possibly lead to increased levels of substance use among adolescents if new prevention measures are not implemented. the intensification of law enforcement strategies to reduce psychotropic substances access is required.

Estupros no Brasil e relações com o consumo de álcool: estimativas baseadas em autorrelato sigiloso

Com base na análise dos dados de corte transversal provenientes do Segundo Levantamento Nacional de Álcool e Drogas realizado em 2012, utilizando-se uma amostra probabilística estratificada por conglomerado representativa da população brasileira, este estudo apresenta as prevalências de estupro e analisa a relação deste evento com o consumo de álcool. Foram considerados 1.918 homens e 2.365 mulheres, totalizando uma amostra de 4.283 indivíduos. Nossos resultados estimam a prevalência de estupro na vida em 2,6% da população geral, sendo 1,7% entre os homens e 3,5% entre as mulheres. Para ambos os sexos, as maiores prevalências se concentraram entre indivíduos com idades entre 26 e 59 anos (3,3%), com baixa escolaridade (3,8%), solteiros, divorciados ou viúvos (3,1%). Entre os indivíduos com diagnóstico para transtorno por uso de álcool de acordo com o DSM-5 (Manual Diagnóstico e Estatístico de Transtornos Mentais), 6% relataram ser vítimas de estupro, bem como, 3,3% daqueles que disseram beber pesado episódico (binge). Análises de regressão logística e multifatorial indicaram que tanto para mulheres quanto para homens a idade (aqueles entre 26 e 59 anos), o estado civil (solteiro), o diagnóstico de transtorno por uso de álcool e o beber pesado episódico são fatores associados ao aumento da probabilidade de vitimização por estupro, enquanto maior nível de educação (mais do que 9 anos de estudos) revelou-se um fator capaz de diminuir as chances de ocorrência. A identificação da amplitude desse problema de saúde pública, bem como a avaliação da urgência na implantação de medidas preventivas e assistenciais, partem do conhecimento das prevalências e do perfil sociodemográfico das vítimas
