Long hours raise risk of unhealthy level of drinking
People working long hours are significantly more likely both to consume more alcohol and to become risky drinkers, this meta-analysis of 63 studies reveals. The analysis of cross-sectional studies, which included more than 333,000 participants, finds that those working long hours are 11% more likely to drink more alcohol than those doing standard hours (adjusted odds ratio (OR) = 1.11; CI 1.05–1.18). The analysis of prospective cohort studies revealed a 12% raised risk of ‘new onset risky alcohol use’ (OR = 1.12; CI 1.04–1.20) – defined as drinking more than 14 units/week for women and over 21 units/week for men, having been within recommended limits at the start of a study. The associations were independent of age, sex, socioeconomic status or geographic region.
