Abstract

Smoking is the most common cause of death related to health behavior. So, many studies on the relation between smoking status and diseases have been reported all around the world. As with increasing interest on healthy living these days, studies focusing on the relationship between smoking status and HRQoL have been conducted. In this study, we intended to analyze the factors related to HRQoL according to smoking status in Korean men and women.In 4th National Health and Nutrition Examination Survey(2007-2009), which was done with 17,424 subjects who are more than nineteen years old, the gap of HRQoL was examined according to gender and so was how smoking is related to it.Assessment of HRQoL was done by EQ-5D(The EuroQol Group, 1990) and Korean Quality Weight Model(Hae sung Nam, 2007). High and low groups were classified on the basis of 0.94, EQ-5D index, as standard. High group was over standard and low one was under standard.Socio-economic features, chronic illness, health behavior, subjective health status and HRQoL were analyzed in men and women. By Model I(with adjustment of age), Model II(with adjustment of demographic, socio-economic feature) and Model III(with adjustment of health behavior), smoking status and HRQoL were divided according to gender and Survey Logistic Procedure was done. Women showed a lower QoL figure (0.92±0.0) than men (0.96±0.0) in HRQoL and the difference was a statistically significant one (p<0.0001). Relevant factors to increase HRQoL involved high level of education and economic, subjective health status. Relevant factors to decrease HRQoL involved aging, chronic illness, depression, smoking, stress awareness, suicidal thoughts. And so on(p<0.0001). In the case of obesity, only women showed low QoL.In men, there was no relation between smoking status and level of HRQoL. However, the results in women showed a significant relationship between smoking status and HRQol in Model I(Odds ration, OR, 1.6[95% confidence Interval, CI, 1.3-2.0] for former smokers; OR 1.8 [95% CI, 1.4-2.3] for current smokers).Even when demographic, socio-economic feature, and health behavior were adjusted, they showed similar results(Model II: OR= 1.5[1.2-1.9]/ 1.6[1.3-2.1], Model III: OR= 1.5[1.2-1.9]/1.7[1.3-2.1]).In the study, women showed low HRQoL. In contrast to men, smoking women had higher risk to be involved in the lower HRQoL group.Henceforth, the study on how HRQoL can be improved when smoking women quit smoking is crucially required to be done.
