Abstract The study aimed to investigate the association between early sexual initiation and alcohol consumption in adolescents. This is a cross-sectional and school-based study that had as a scenario 22 public high schools, selected by random technique and stratified by conglomerates in two stages. The total sample consisted of 1154 students regularly enrolled in schools and selected classes, aged 13 to 18 years. The collection was carried out through the application of the Youth Risk Behavior Survey, validated and translated into Brazilian Portuguese. The data were analyzed with the aid of the SPSS program version 20.0, adopting a level of significance of 5%. Multivariate analysis was used to evaluate the association between variables, and sex stratification was performed to test association with alcohol consumption patterns and the age of sexual debut. 47.7% of the sample was already sexually active, of which 24% had the first relationship with less than 15 years. Among the sociodemographic factors analyzed, only sex and religion reached significance. The stratified analysis showed a statistical association between early sexual initiation with the age of the first alcohol dose and the practice of binge in the last 30 days for both sexes. It is concluded that patterns of alcohol consumption can be important factors in the association with early sexual initiation for adolescents of both sexes, and it is necessary to implement public policies that protect this specific population.

Resumo O estudo teve por objetivo investigar associação entre a iniciação sexual precoce e o consumo do álcool em adolescentes. Trata-se de um estudo transversal e de base escolar que teve por cenário 22 escolas públicas de ensino médio, selecionadas por meio de técnica aleatória e estratificadas por conglomerados em dois estágios. A amostra total foi composta por 1154 alunos regularmente matriculados nas escolas e nas classes selecionadas, com idade entre 13 a 18 anos. A coleta ocorreu por meio da aplicação do questionário Youth Risk Behavior Survey, validado e traduzido para o português do Brasil. Os dados foram analisados com auxílio do Programa SPSS versão 20.0, adotando nível de significância de 5%. Análise multivariada foi utilizada para avaliar a associação entre as variáveis, sendo realizado estratificação por sexo para testar associação com os padrões de consumo de álcool e a idade do início sexual. 47,7% da amostra já era sexualmente ativa, sendo que destes, 24% tiveram a primeira relação com menos de 15 anos. Dentre os fatores sociodemográficos analisados, apenas o sexo e a religião atingiram significância. A análise estratificada mostrou associação estatística entre iniciação sexual precoce com a idade da primeira dose de álcool e a prática de binge nos últimos 30 dias para ambos os sexos. Conclui-se que os padrões de consumo de álcool podem se configurar como fatores importantes na associação com o início sexual precoce para adolescentes de ambos os sexos, sendo necessária a implementação de políticas públicas que protejam essa população específica.

ABSTRACT OBJECTIVE To determine the prevalence of cigarette use among adolescents and to identify associated health risk behaviors. METHODS This is a cross-sectional study with a representative sample, composed of 1059 adolescents between 13 and 19 years old, enrolled in primary and secondary public schools of Olinda, Pernambuco, in 2014. Information was obtained through self-administered questionnaires (validated version of YRBS 2007). Cigarette experimentation was defined as smoking at least once in life. Adolescents who smoked at least one day within 30 days prior to the survey were considered current smokers. Most students were female and 16 years old or older. RESULTS Almost 30% used it in life and about 10% smoked within the 30 days before the survey. Suicidal ideation (PR = 1.51, 95%CI 1.25–1.82), alcohol use (PR = 1.41, 95%CI 1.03–1.92), marijuana (PR = 1.64, 95%CI 1.37–1.96), excessive alcohol consumption (PR = 1.57, 95%CI 1.15–2.16) and sexual experience (PR = 1.78, 95%CI 1.43–2.21) have increased the risk of using cigarettes. Feelings of sadness (PR = 1.70, 95%CI 1.22–2.36), alcohol use (PR=2.40, 95%CI 1.12–5.12), excessive alcohol consumption (PR = 2.5, 95% CI 1.24–5.38), marijuana (PR = 2.31, 95%CI.57–3.39) and cocaine (PR = 1.99, 95%CI.32–3.01) increased the risk of cigarette use within the 30 days before the survey. CONCLUSIONS Cigarette use among adolescents from Olinda was high, being considered higher than the national prevalence. Possible factors associated with cigarette use were drug use (alcohol, marijuana, and cocaine) and behaviors related to sexual experience, feelings of sadness and suicidal ideation.

RESUMO OBJETIVO Estimar a prevalência do uso de drogas ilícitas e sua associação com binge drinking e fatores sociodemográficos entre estudantes adolescentes. MÉTODOS Estudo transversal com amostra probabilística por conglomerado, envolvendo 1.154 estudantes, de 13 a 19 anos de idade, da rede pública de ensino, no município de Olinda, PE, 2014. Foi utilizado o questionário Youth Risk Behavior Survey, validado para uso com adolescentes brasileiros. Para análise dos dados foi utilizado o teste do Qui-quadrado (≤ 0,05) e análise de regressão de Poisson, para estimar razões de prevalência, com intervalos com 95% de confiança. RESULTADOS O uso na vida de drogas ilícitas foi quatro vezes mais prevalente entre os estudantes que relataram o binge drinking (IC95% 3,19–5,45). Estar na faixa etária de 16 a 19 anos, ser do sexo masculino e não ter religião também foram significativamente associados ao uso de drogas ilícitas. CONCLUSÕES A prevalência do uso de drogas ilícitas na vida foi superior a outros estudos realizados no Brasil e esteve fortemente associado ao binge drinking. Esse fator mostrou associação com gênero, idade e religião.

ABSTRACT OBJECTIVE To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students. METHODS This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals. RESULTS Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19–5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use. CONCLUSIONS The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion.
