title: Association of smoking status with quality of life in a cross-sectional population-based sample of Iranian adults: Isfahan Healthy Heart Program.
abstract: This study aimed to examine the association between smoking status and quality of life (QOL) in a population-based sample of Iranian adults. The study used data from the Isfahan Healthy Heart Program (IHHP). A total of 5830 participants were included. They were categorized as current, former, or never smokers. QOL was evaluated using the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), Persian version. Data entry was performed using SPSS (SPSS Inc, Chicago, IL) software version 13.0. QOL was associated with marital status (P = .014), education (P = .001), occupation (P = .007), and income (P < .000) among current smokers. After adjusting for sociodemographic characteristics, smoking decreased QOL among current (odds ratio [OR] = 0.98; 95% confidence interval [CI] = 0.97-0.99) and past (OR = 0.97; 95%CI = 0.95-0.98) smokers relative to never smokers. QOL is lower among Iranian current and past smokers, and the relation is independent of underlying sociodemographic factors.
