Smoking cessation and quality of life: the effect of amount of smoking and time since quitting

BACKGROUND: Knowledge of the impact of smoking cessation on health-related quality of life may be important in encouraging smokers to quit. We determined whether the difference in quality of life between ex- and current smokers is influenced by amount of smoking or time since quitting. METHODS: Data were collected within a cross-sectional study among a random sample of the general population in The Netherlands. Health-related quality of life was measured with the RA36 questionnaire (adapted from 36). Smoking behavior was assessed with a self-administered questionnaire. Adjusted differences in quality of life scores between ex- and current smokers were tested with multivariate analysis of variance, among 9,660 men and women aged 20-59 years, without history of tobacco-related chronic diseases. RESULTS: Ex-smokers reported significantly higher quality of life scores than current smokers. This was more pronounced for mental health, especially for role functioning limitations due to emotional problems (difference 6.5 points; P < 0.0001), than for physical health dimensions. Differences were generally larger between ex- and current heavy smokers than between ex- and current light or moderate smokers (P trend <0.05 when ex-smokers had quit <5 or > or =10 years ago). No significant trend was observed with time since quitting. CONCLUSIONS: Generally, the higher the amount of smoking, the higher were quality of life differences between ex- and current smokers.
