Abstract 3979: Is Duration of Smoking Cessation in Older Ex-Smokers Related to Health Related Quality of Life? Findings from the Chicago Heart Association Detection Project in Industry (CHA)
Background: Although studies on the association of smoking cessation and health-related quality of life (HRQOL) exist, little is known about the relationship between cessation duration and HRQOL among older ex-smokers from population-based studies.
Methods: The sample consists of 2118 men and 847 women from the CHA Study ages ≥65 in 2003. Participants were ex-smokers and had HRQOL assessment by Health Status Questionnaire-12 (HSQ-12) scores measuring health perception, and physical and mental well-being also in 2003. The higher the HSQ-12 score, the better the outcome. Duration of smoking cessation was categorized into 3 levels: short (less than 10 years), moderate (10–29 years), and long (≥30 years).
Results: Mean age was 75.3 for men and 77.3 for women. On average, a higher proportion of men quit smoking for ≥30 years than women (49.8% vs. 37.4%). With adjustment for age, race, education, marital status, living arrangement, alcohol use, body mass index, and number of cigarettes smoking/day in the past, means of HSQ-12 scores of physical, mental, and social functioning were lowest (worse) among older ex-smoker men with shortest cessation duration (< 10 years) and highest (better) among those who had quit smoking for more than 30 years or longer (p-trends <0.001) - see Table⇓. The association remained strong and significant with further adjustment for comorbidities. However, no association was observed in older ex-smoker women.
Conclusions: Longer duration of smoking cessation in older ex-smoker men is associated with higher HRQOL. A smoking cessation intervention early in life could have a great potential to improve quality of life in older age. More research is needed to determine reasons for the lack of association between length of smoking cessation and quality of life in women.
