Abstract

Objective To assess the relationship between smoking status and health-related quality of life 1 year after participation in a smoking cessation programme in Taiwan.

Design A cohort study of smokers who voluntarily participated in a smoking cessation programme with two follow-up assessments of smoking status via telephone interview, conducted 6 months and 1 year after finishing the smoking cessation programme.

Setting Hospitals and clinics providing smoking cessation services.

Participants A total of 3514 participants completed both telephone interviews, which represents a response rate of 64%. After the interviews, participants were divided into four groups according to their smoking status: (1) long-term quitters: participants who had quit tobacco use for 1 year; (2) short-term quitters: participants who had been smoking for at least 6 months and then quit tobacco for 6 months after participating in the programme; (3) relapsed smokers: participants who relapsed into tobacco use after ceasing tobacco use for 6 months; and (4) continuing smokers: participants who failed to quit smoking for at least 1 year, despite participating in the programme.

Interventions The Outpatient Smoking Cessation Service of Taiwan provides counselling and pharmacotherapy to individuals seeking to quit smoking.

Primary outcomes The health-related quality of life of the participants was measured using an approved Chinese version of the EuroQol-5D-3L (EQ-5D-3L) descriptive system.

Results After controlling for sex, age, education, marital status, job status, monthly income and disease status at baseline, our results revealed that long-term (OR=0.61 (0.48 to 0.77)) and short-term (OR=0.65 (0.54 to 0.79)) quitters experienced less anxiety and depression than did continuing smokers.

Conclusions Our study provides evidence to support claims that all quitters, regardless of whether they stop smoking for 6 months or 1 year, have better quality of life with regard to anxiety or depression.
