Age at menarche and current substance use among Canadian adolescent girls: results of a cross-sectional study

摘要

BackgroundSubstance use is among the key public health threats that find its genesis during adolescence. Timing of puberty has been lately researched as a potential predictor of subsequent substance abuse. The present study, therefore, aims to assess the effect of age at menarche on current practices of smoking, alcohol drinking and drug use among 14-15 year old Canadian girls.
