Reduced probability of smoking cessation in men with increasing number of job losses and partnership breakdowns
Résumé
Background: Unemployment and partnership breakdowns are common stressful life events, but their association with smoking cessation has been investigated in a few studies only. Objective: To investigate how history of employment and cohabitation affect the probability of smoking cessation and to study joint exposure to both. Methods: Birth-cohort study of smoking cessation of 6,232 Danish men born in 1953 with follow-up at age 51 (response rate 66.2 %). History of unemployment and cohabitation was measured annually using register data. Information on smoking cessation was obtained by questionnaire. Results: Probability of smoking cessation decreased with number of job-losses (ranging from 1 OR 0.54 95% CI (0.46-0.64) to 3+ OR 0.41 95% CI (0.30-0.55)) and of broken partnerships (ranging from 1 OR 0.74 95% CI (0.63-0.85) to 3+ OR 0.50 95% CI (0.39-0.63)). Furthermore, smoking cessation was associated with the duration of the periods of unemployment (ranging from 1-5 years OR 0.75 95% CI (0.65-0.85) to 10-23 years OR 0.29 95% CI (0.22-0.38)) and with living without a partner for more than five years (ranging from 6-9 years to 10 to 23 years OR 0.80 95% CI (0.66-0.97) to 10-23 years OR 0.44 95 CI (0.37-0.52)). Those who never cohabited and experienced one or more job-losses had a particular low chance of smoking cessation (OR 0.19 95% CI (0.12-0.30). Conclusion: Number of job-losses and of broken partnerships were both inversely associated with probability of smoking cessation.
