Drinking, smoking, and psychological distress in middle and late life.

A limited number of studies have examined the co-occurrence of alcohol use and smoking and their mental health effects in middle and late life. In this study, using the 2008 National Survey of Drug Use and Health, the characteristics of individuals aged 50 and older who abstained from both substances, who used both substances, and who used one or the other substance were examined. Then, the main and interaction effects of drinking and smoking on psychological distress were analyzed. Findings show that smoker-nondrinkers are the most disadvantaged group in terms of sociodemographic and health characteristics, while drinker-nonsmokers are the most advantaged group. When sociodemographic, health, and other factors were controlled, no direct effects of drinking or interaction effect of drinking and smoking were detected for either gender. However, heavy smoking (6+ cigarettes on a typical smoking day) was significantly associated with an elevated level of psychological distress among women. The findings highlight the vulnerability of heavy smoking middle-aged and older women. These women are the most psychologically distressed and may need interventions designed to help them quit smoking, reduce or quit drinking, and alleviate psychological distress.
