Alcohol consumption in the under-18 age group has been growing in recent years, leading to various health risks. Considering the problems this habit brings, the present study contributes to the literature dedicated to categorizing different types of drinkers. The study objective is to verify the factors associated with the intensity of alcohol use among elementary school students in the year 2015. The dataset came from the National Adolescent School-based Health Survey (PeNSE). The applied methodology was a logit model of sequential response (continuation ratio). The main results are as follows. It was found that being female is associated with a lesser chance of having consumed alcohol in the reference period, however, with a greater chance of consuming five or more doses. Economic condition and formal paid employment are positively associated with alcohol consumption, which increases with the progression of the student’s age. The number of friends who drink alcohol and consumption of products originating from tobacco and illicit drugs, are good predictors of alcohol use by students. The time spent practicing physical activities increased the chance of male students consuming alcohol. The results showed that, in general, the characteristics associated with different alcohol consumption profiles remain similar but differ between genders. Intervention strategies aimed at preventing alcohol consumption by minors are suggested in order to reduce the negative effects of substance use and abuse.

Resumo Este artigo possui como objetivo principal verificar como um grupo de características sociodemográficas afeta a probabilidade de ocorrência de diferentes níveis de insegurança alimentar no Brasil, levando em conta a complexidade informacional oferecida pela Escala Brasileira de Insegurança Alimentar (EBIA). A hipótese que avaliamos, através da proposta de aplicação de um modelo logístico ordenado generalizado, é a de que se observam efeitos assimétricos das variáveis explicativas em relação às diferentes categorias de insegurança alimentar da EBIA. Os resultados confirmam essa hipótese, alertando para a importância de se considerar a complexidade desse fenômeno na elaboração de políticas públicas nessa área.
