Alcohol and other psychoactive substances in Africa and the Americas: results from the WHO Global School-based Student Health Survey

Abstract

Objective: The objective of this study was to estimate the prevalence of current alcohol use and its association with cigarette and drug use among 13–15-year-olds in Africa and the Americas.

Method: Cross-sectional data of the WHO Global School-based Student Health Survey from nine countries in the WHO African Region and seven countries/territories in the WHO Region of the Americas were analysed. Single and joint prevalence rates, and prevalence odds ratios were computed.

Results: In the majority of countries, alcohol was the most often consumed psychoactive substance, with the prevalence of current alcohol use outweighing the prevalence of current cigarette and lifetime drug use. Gender differences for alcohol were not marked. The use of alcohol was strongly associated with cigarette or drug use, indicating clustering.

Conclusions: For the bulk of countries in the Americas and for single countries in Africa, current alcohol use is as high as prevalence rates occurring in other parts of the world. It is imperative to monitor psychoactive substance use among adolescents in these countries to be able to prevent future health and social harm with the information gained.
