Background: Smoking is known to increase the risk of chronic disease. Understanding of factors that contribute to smoking cessation may help to develop strategies for smoking behavior change. Methods: Pooled cross-sectional data of 11,924 subjects from the Korea National Health and Nutrition Examination Survey II-V were analyzed. The stages of change in smoking cessation were categorized into pre-contemplation, contemplation, and preparation. Baseline characteristics, socioeconomic factors, quality of life, psychological characteristics, and tobacco-related factors were compared between the groups. Results: The study population consisted of 32.4% in pre-contemplation, 54.4% incontemplation, and 13.1% in preparation group. While the proportion for pre-contemplation group (37.4% to 28.4%) tended to decrease from 2001 to 2012, that of preparation group (6.4% to 18.1%) tended to increase. The mean age of pre-contemplation group (48.4±16.2) is higher than comtemplation and preparation group (42.2±13.9 and 44.4±15.3; P=0.02). As levels of education and income status increased, the proportion of pre-contemplation tended to decrease, and that of preparation tended to increase. Proportion of blue collar job in pre-contemplation group was higher than in preparation group (67.9% vs 58.1%; P<0.001). In pre-contemplation group, percentage of suicidal ideation within 1 year was higher than contemplation and preparation group19.3% vs 16.0% and 16.1%). Upon adjusting analysis, the proportion of pre-contemplation group increased with increasing age (OR=1.01; 95%CI 1.01-1.02), and smoking amount (OR=1.04; 95%CI 1.03-1.05). People of pre-contemplation group (vs. preparation) are be less educated (OR=1.99; 95% CI 1.51-2.62), are in single marital status (OR=1.25; 95%CI 1.04-1.50), have lower prevalence of cardiovascular disease OR=0.48; 95%CI 0.31-0.76), and do less exercise walking (OR=1.36; 95%CI 1.09-1.69)and weight training (OR=1.59; 95%CI 1.35-1.85). Conclusions: We demonstrated a signifi cant association between the stages of changesmoking cessation and age, education, marital status, cardiovascular disease, and amount of exercise.

SunMi Kim,JaeWoo Jung,InWon Park,ChulMin Ahn,YuIl Kim,KwangHa Yoo,EunMi Chun,JiYe Jung,YoungSik Park,JuHeon Park,JaeYeol Kim,Korean Smoking Cessation Study Group 대한신경정신의학회 2016 PSYCHIATRY INVESTIGATION Vol.13 No.2

Objective-As mental health problems may play an important role in initiating and maintaining cigarette smoking in females and there are an increasing number of female smokers, we evaluated the relationship between smoking status and mental health problems including depression and suicide ideation in women in Korea. Methods-We analyzed the 5-year cumulative data (19 years of age or older, n=32,184) from the Korean National Health and Nutrition Examination Survey (KNHANES) conducted from 2008 to 2012. Logistic regression analyses were used to evaluate associations between cigarette smoking status and mental health parameters while controlling for potentially confounding variables. Results-Among current smokers, females showed higher lifetime prevalence in having a depressive episode, a doctor-diagnosed major depression, a current diagnosis of depression, or receiving treatment for depression in comparison with males. In addition, females were more likely to report on having a depressive episode, suicidal ideation and attempts, and psychiatric counselling within the previous year, as compared to males. Female former smokers showed intermediate characteristics in parameters of mental health status within the previous year, ranking between lifetime non-smokers and the current smokers. Conclusion-Identifying the factors related to mental health status among current smokers can increase opportunities for an early intervention and help reduce the prevalence of smoking and increase smoking cessation rates particularly in females. Developing adaptive coping strategies other than smoking in female youth is potentially important in reducing the initiation of smoking.

Background: Many studies investigated that smoking is the major cause of various physical illnesses, but the relationship between smoking status and mental health including suicidal ideation and suicidal attempts was not studied. This study was conducted to evaluate whether cigarette smoking status was related with mental health including suicidal ideation and suicidal attempts in Korean adult population. Methods: We used data from the fourth and fifth annual South Korean National Health and Nutrition Examination Survey (Korean NHANES IV) conducted in 2008,2009, 2010, 2011 and 2012. From a total of 45,811 subjects, 32,184 adult subjects who were at least 19 years of age were included in the study population. The correlation between smoking status and mental health using questionnaires about mental health, cigarette smoking and diagnosis of major depressive disorder were analyzed. They were adjusted by age, income, education and marital state. Results: In male, current smoker was 42.4%, former smoker 38.9% and non smoker18.7% and in female, 5.9%, 5.6% and 88.4%. Age, quartile of income, education state and marital state were different according to smoking status (P<0.001). In male and female, perceived stress was higher and EQ-VAS in current smoker was lower than those in non smoker (P<0.001). The incidence of major depressive disorder in current smoker female was higher than that in non smoker female (8.4% vs. 4.5%, OR=1.945, 95% CI: 1.536-2.463). In female, current smoker had higher prevalence of suicidal ideation and suicidal attempts in last year compared with non smoker (OR=1.912, 95% CI: 1.659-2.203, OR=3.930, 95% CI: 2.701-5.719, respectively).Conclusion: In the current study, current smoking was signifi cantly related with major depressive disorder, depression symptom and suicidal ideation and attempts in Korean females.

Background: This study aimed to investigate the association between e-cigarette (EC) use and development of acute severe pneumonia in the Korean population using a national database. Methods: We conducted a retrospective analysis using linkage of data between the Korean National Health and Nutrition Examination Survey (KNHANES) and the National Health Insurance Service (NHIS) administrative claims database. The primary endpoint of this study was development of severe pneumonia requiring hospital admission according to EC use during the study period. The secondary endpoints were in-hospital mortality, intensive care unit (ICU) admission, ventilator care, and days of hospital stay. Results: The final analysis included 28,950 individuals, of which 578 (2.0%) were EC users. EC users were younger and more often male than non-EC users. The EC users showed higher level of education and household income and had fewer comorbidities. Severe pneumonia was noted in 37 of 28,372 non-EC users (0.13%), but there were no occurrences of severe pneumonia in EC users. The incidence of pneumonia occurrence was not different between the two groups (P = 1.000). Conclusions: Since e-cigarette or vaping use-associated lung injury (EVALI) is most likely included in acute severe pneumonia occurring within 3 months of EC use, it is considered that there might be no EVALI patients in Korea during the investigation period. A large-scale, prospective study is necessary to evaluate the association between EC use and acute lung injury.
