Background: Alcohol consumption remains a major societal problem, contributing to myriad health conditions. Australian midlife women (aged 45-64 years) consume more alcohol than previous generations of midlife women and more than younger women now. Alcohol poses health risks that are unique to midlife women, including increased risk of breast cancer; 10% of breast cancers result from alcohol consumption and there is no “safe” limit. There is a global gap in knowledge about socially and culturally appropriate interventions for reducing alcohol consumption in these heavy-drinking groups of midlife women.
