Prospective Associations Between Alcohol Consumption and Psychological Well-being in Midlife
Abstract Background: Alcohol consumption potentially influences psychological well-being in beneficial and harmful ways, but prospective studies on the association show mixed results. Our main purpose was to examine prospective associations between alcohol consumption and psychological well-being in middle-aged men and women. Methods: The study sample included 4,148 middle-aged individuals (80% men) from the Copenhagen Aging and Midlife Biobank who reported their alcohol consumption (average weekly consumption and frequency of binge drinking) at baseline in 2004 or 2006 and reported their psychological well-being (satisfaction with life and vitality) at follow-up in 2009–2011. Analyses were adjusted for sociodemographic factors, lifestyle, social relations, and morbidity.Results: For satisfaction with life at follow-up, lower scores were observed in men and women who were alcohol abstinent at baseline as well as in men with heavy alcohol consumption compared with moderate alcohol consumption at baseline. Moreover, men with moderate frequency of binge drinking (1–3 times/month) at baseline had higher satisfaction with life scores at follow-up than men with less and more frequent binge drinking. In relation to vitality at follow-up, alcohol abstinence at baseline in men and women and heavy alcohol consumption at baseline in men were associated with lower scores compared with moderate alcohol consumption. Conclusions: Alcohol abstinence seems to be prospectively associated with adverse psychological well-being in men and women, while heavy alcohol consumption seems to be prospectively associated with adverse psychological well-being in men. Finally, an inverse u-shaped prospective association between binge drinking and life satisfaction was observed in men.
