Aim Comprehensive research for factors related to healthy lifestyles of the elderly is limited. The present study aimed to elucidate the factors associated with adherence to a healthy lifestyle by age groups. Method The present study was based on data from the 2005 K orea N ational H ealth and N utrition E xamination S urvey. We calculated crude proportions and adjusted proportions of cigarette smokers, problem alcohol drinkers, and physically inactive people in two age groups (40−59 years and ≥60 years). We carried out multilevel analysis to elucidate factors associated with healthy lifestyles. Results Of 3194 respondents included in the analysis, 1154 (36.13%) were aged 60 years or older. Older participants smoked less (23.0% vs 17.4%) and exercised less frequently (52.4% vs 66.9%; all P < 0.001) than their middle‐aged counterparts. After adjustment, the proportion of regular exercisers was inversed (adjusted proportion 0.468, 95% CI 0.436–0.501 vs 0.377, 95% CI 0.337–0.419, P = 0.004). In multilevel analysis, contextual factors, such as local tax per capita, was associated significantly with cigarette smoking only in the elderly ( OR 1.037, 95% CI 1.005–1.070). Conclusions Different factors were associated with healthy lifestyles of elderly people when compared with middle‐aged people. In addition, local tax per capita, an area level variable, was more likely to be associated with smoking in the elderly than the middle‐aged group. Geriatr Gerontol Int 2015; 15: 778–788.
