Mid-Adolescent Predictors of Adult Drinking Levels in Early Adulthood and Gender Differences: Longitudinal Analyses Based on the South Australian School Leavers Study

الملخص EN

There is considerable public health interest in understanding what factors during adolescence predict longer-term drinking patterns in adulthood.

The aim of this study was to examine gender differences in the age 15 social and psychological predictors of less healthy drinking patterns in early adulthood.

The study investigates the relative importance of internalising problems, other risky health behaviours, and peer relationships after controlling for family background characteristics.

A sample of 812 young people who provided complete alcohol consumption data from the age of 15 to 20 years (5 measurement points) were drawn from South Australian secondary schools and given a detailed survey concerning their psychological and social wellbeing.

Respondents were classified into two groups based upon a percentile division: those who drank at levels consistently below NHMRC guidelines and those who consistently drank at higher levels.

The results showed that poorer age 15 scores on measures of psychological wellbeing including scores on the GHQ-12, self-esteem, and life-satisfaction as well as engagement in health-related behaviours such as smoking or drug-taking were associated with higher drinking levels in early adulthood.

The pattern of results was generally similar for both genders.

Higher drinking levels were most strongly associated with smoking and marijuana use and poorer psychological wellbeing during adolescence.
