Maori Identification, Alcohol Behaviour and Mental Health: A Review

Population-Level Impacts of Alcohol Use on Mental and Physical Health Outcomes

This study explores patterns of alcohol drinking within a representative New Zealand sample (2887 participants (1464 female, 1423 male)). Alcohol use and drinking patterns across the population are described. Multivariable logistic regressions document associations between alcohol use and drinking patterns and the likelihood of experiencing different health outcomes. Alcohol use, early drinking initiation, frequent drinking, and heavy episodic drinking (HED) are prevalent in New Zealand and vary in relation to gender, age, and socioeconomic characteristics. Those who reported alcohol-related problems were more likely to report poor mental health (AOR: 2.21; 95% CI: 1.42-3.46) and disability (AOR: 1.79, 95% CI: 1.06-3.00), and less likely to experience positive mental health (AOR: 0.28, 95% CI: 0.18-0.42). Those who reported HED were also less likely to experience good general health (AOR: 0.61, 95% CI: 0.47-0.81) and positive mental health (AOR: 0.67, 95% CI: 0.53-0.84). Younger age cohorts were more likely to engage in early drinking, and those who initiated regular drinking before age 18 were more likely to report HED and alcohol-related problems. Findings indicate that problem drinking and HED are not only associated with poor physical health, but also reduce the likelihood of individuals experiencing positive mental health. This provides information to enable public health practitioners to target alcohol prevention strategies at the entire population of drinkers.
