Smoking and functional status among Medicare managed care enrollees.

Abstract Background Smoking is a major determinant of health status and outcomes. Current smoking has been associated with lower scores on the Short Form-36 Health Survey (SF-36). Whether this occurs among the elderly and disabled Medicare populations is not known. This study assessed the relationships between smoking status and both physical and mental functioning in the Medicare managed-care population. Methods During the spring of 1998, data were collected from 134,309 elderly and 8640 disabled Medicare beneficiaries for Cohort 1, Round 1 of the Medicare Health Outcomes Survey. We subsequently used these data to calculate mean standardized SF-36 scores, self-reported health status, and prevalence of smoking-related illness, by smoking status, after adjusting for demographic factors. Results Among the disabled, everyday and someday smokers had lower standardized physical component (PCS) and mental component (MCS) scores than never smokers (−2.4 to −4.5 points; p p Conclusions In the elderly and disabled Medicare populations, smokers report worse physical and mental functional status than never smokers. Long-term quitters have better functional status than those who still smoke. More effort should be directed at helping elderly smokers to quit earlier. Smoking cessation has implications for improving both survival and functional status.
