Tobacco and alcohol use; suicide ideation, plan, and attempt among adolescents; and the role of legal purchase age restrictions: a pooled population-based analysis from 58 countries.

ABSTRACT:

Background

We aimed to evaluate the potential independent and interactive associations of tobacco and alcohol use with suicide ideation, plan, and attempt among adolescents, and the role of legal purchase age restrictions among these associations.

Methods

A pooled cross-sectional analysis was conducted with data from the Global School-based Student Health Survey (GSHS) (2013-2019), the US Youth Risk Behavior Surveillance System (YRBSS) (2021), and a Chinese school-based health survey (2017). Self-reported use of tobacco and alcohol during the past 30 days, and suicide ideation, plan, and attempt during the past year, were collected from questionnaires. Country-level purchase age restrictions on tobacco and alcohol products were obtained from official government websites.
