As smokers get older, they tend to quit smoking in association with declining health and economic status. However, the association with the changes in work and life situations in the older age has not been fully explored. This study investigated the factors associated with current smoking among older persons in Korea, using the data from 2016 survey as part of Korean Longitudinal Study of Ageing (KLoSA). Multiple logistic regression analysis was used for current smoking .as the dependent variable. Of the 6618 participants, average age was 70.8 years (range 56-108), 58% were women, and 10.3% were current smokers, including 1.6% of women and 22.3% of men. The factors associated with current smoking included younger age (p<0.01), being male (OR 19.1, p<0.01), single (OR 1.5, p<0.05), currently employed (OR 1.4, p<0.01) or self-employed (OR 1.3, p<0.05), no social life engagement (OR 1.6, p<0.01), and having fewer than 2 chronic diseases (OR 1.4, p<0.01). This study suggests that smoking cessation messages need to be adapted to the evolving work and life contexts among older persons.
