Do the reasons people drink alcohol aid our understanding of sociodemographic differences in alcohol-free and low-alcohol consumption? A path analysis on a cross-sectional study of adult alcohol drinkers in Great Britain.

BackgroundIn the UK, consumption of alcohol-free and low-alcohol (NoLo) drinks is more prevalent among heavier drinkers and socially advantaged groups. If heavier drinkers are substituting alcoholic drinks with NoLo drinks, this could improve public health. However, socioeconomic differences in consumption could exacerbate alcohol-related health inequalities. Socioeconomic groups vary in their reasons for drinking alcohol, with less advantaged individuals more likely to drink alcohol to cope. This study examined whether alcohol drinking motives can help explain differences in NoLo consumption, with a particular aim of understanding socioeconomic differences.Methods2,555 adults residing in Great Britain provided data on at-least monthly NoLo consumption, hazardous drinking (AUDIT-C), alcohol drinking motives, social grade, education, age, and gender, via the Alcohol Toolkit Study. Path analysis explored the mediating effects of drinking motives between sociodemographic characteristics, hazardous drinking, and NoLo consumption.ResultsDrinking alcohol to conform, education, and hazardous drinking were positively associated with NoLo consumption. Drinking alcohol to cope with depression was a serial mediator between social grade and NoLo. Drinking to cope with depression, more frequently reported among lower social grades, weakened the positive relationship between hazardous drinking and NoLo consumption (β = -0.001, 95% CI -0.002, -0.000). Enhancement and social motives also weakened this relationship, partially mediating pathways between age, gender, education, and NoLo consumption.Discussion Whilst hazardous drinking is positively associated with NoLo consumption, for those drinking to cope with depression, for enhancement, or social reasons, this effect is diminished, potentially limiting the public health potential for these groups.
