The health effects of alcohol are determined not only by level of intake but also by patterns of alcohol use and many other health determinants. This study seeks to identify groups of individuals who share various features in terms of drinking styles and other health indicators. Data used are a subset of the 1990 Ontario Health Survey, corresponding to men and women aged 20-64 with complete data in four substantive areas: alcohol use; demographic characteristics; current health status; and various behavioural risk factors for chronic disease. Cluster analysis was used to groups of male and female respondents who were similar in terms of their style of alcohol use, along with other constructs relevant to health risk and health status. For both sexes, clusters were identified which matched expectation in terms of drinking patterns and other relevant variables. For both sexes, clusters were found with generally higher social class indicators, generally positive health behaviours and health status and drinking patterns which did not include drinking to excess. Clusters were also found for which high-volume drinking occasions corresponded with poor health status and high levels of risk factors for chronic disease. Other unanticipated patterns were also identified. This information may assist in identifying confounding effects in epidemiological studies as well as identifying the characteristics of unique sub-populations which are likely to be the focus of primary prevention efforts.
