Impact of the transition to retirement on alcohol consumption: a longitudinal analysis within SHARE

Abstract In an ageing society, the impact of retirement on behavioural risk factors and health status needs to be carefully assessed. Evidence on the short-term and long-term effects of retirement on alcohol consumption are contrasting and inconsistent. A longitudinal study was conducted based on data from the Survey on Health, Ageing and Retirement (SHARE) collected between 2004 and 2020 in 27 European countries and Israel. A repeated measure generalised estimating equation (GEE) model was fitted to estimate the relative risks (RR) and corresponding 95% confidence intervals (CI) of alcohol consumption (frequency, quantity, and binge drinking) at different time periods before and after retirement. We selected a cohort of 8,998 individuals who were employed at baseline and retired during follow-up (median follow-up: 9 years; maximum: 16 years). Compared to the year of retirement, the RR for habitual daily or near-daily drinking was 0.88 (95%CI 0.76-1.02) 10 years before retirement and 0.92 (95%CI 0.83-1.02). This pattern reversed post-retirement with a RR of 1.12 (95%CI 1.01-1.23) 3-4 years after retirement and 1.28 (95%CI 1.11-1.48) 10 years or more after retirement. No significant changes in the consumption of high volumes (more than 8 units of alcohol) were observed: while the frequency of regular drinking might increase post-retirement, the instances of heavy episodic drinking do not necessarily rise. Additionally, a reduction in occasional heavy drinking episodes was noted both before (RR 0.86; 95%CI 0.77-0.95, 5-9 years prior) and after retirement (RR 0.78; 95%CI 0.66-0.93, more than 10 years after). These findings underscore the complexity of alcohol use behaviours in the context of retirement. The increase in regular drinking post-retirement might be attributed to changes in daily structure, social interactions, or coping mechanisms for life transitions. The decline in binge drinking suggests a shift towards more moderated consumption patterns as individuals age.
