Retirement transition and smoking and drinking behaviors in older Chinese adults: Analysis from the CHARLS study

Smoking and drinking are important public problems and a substantial part of work culture in mainland China. However, little is known about the effect of retirement on these behaviors. Thus, this study examined the relationships between retirement transition, smoking and excessive drinking among older Chinese adults.Repeated longitudinal data from a nationally representative sample of Chinese adults were collected in 2011, 2013, 2015 and 2018. Respondents completed a structured questionnaire regarding work status and health behaviors. Modified mixed-effects Poisson regression models were used to explore the associations, with additional analyses stratified by gender.Of the 10,378 participants included, 62.6% and 20.1% of men reported current smoking and excessive drinking at study entry; compared to 4.4% and 1.5% of women, respectively. There was no significant association between retirement and smoking. We found a dose-response relationship between time in retirement and excessive drinking in the adjusted model where those who retired >= 2 years ago had a 30% lower risk of excessive drinking (risk ratio (RR) = 0.70, 95% confidence interval (CI) = 0.56-0.86), and those who retired < 2 years ago had a 16% lower risk of excessive drinking (RR = 0.84, 95%CI = 0.73-0.97), compared with those who remained working. This pattern remained when analyzed separately for men and women, although not all results reached statistical significance.Chinese older adults are more likely to reduce drinking following retirement. Such evidence supports the positive framing of retirement in public discourse and the need for workplace interventions to address excessive drinking in China.
