Background
Nationwide evaluation of physicians' smoking rate may be helpful to predict future trend of smoking in a general population. Thus, we investigated physicians' smoking rate and their habits in Korea. Methods: Ten percent of physicians among the registered members of the Korean Medical Association were chosen by stratified random sampling and a mail questionnaire survey was conducted in 2000. Of the 2,977 physicians to whom the questionnaires were delivered, 1,248 (41.9%) responded. Results: Overall smoking rate among Korean doctors was 29.9%. Smoking rate of males was 34.9% and that of females was 2.3%. In the current smokers, the most frequently reported age when they had begun smoking were 15∼20 years (60.3%), the majority of daily smoking amount was less than or equal to 1 pack (92.5%), and those who were planning to quit smoking within 1 month were 11.9%. In the ex-smokers, the most frequently reported age when they had begun smoking were in their 20s (67.7%) and the most frequently reported age when they had stopped smoking were in their 30s (38.0%). Conclusion: The smoking rate of Korean physicians was estimated to be less than that of the general Korean population, but higher than that of physicians in major developed countries. More efforts to lower smoking rate of physicians and regular follow up is needed. (J Korean Acad Fam Med 2007;28:599-603)

Background
Increasing cigarette tax is known to be effective in stopping smoking and preventing initiation of smoking in adolescents. This study was designed to investigate the change of smoking attitudes in high school students after increase in cigarette tax in 2004. Methods: A self-questionnaire study was performed in high school students in Seoul and Chungnam province in June, 2004. The number of respondents was 1,424 consisting of 883 males and 541 females. The factors related to smoking cessation or reduction of smoking amount after increase in cigarette tax were analysed. Results: Among the total 1,424 subjects, 199 (14.0%) students smoked before the increase in cigarette tax. The smoking rate of males and females were 19.5% and 5.0%, respectively. Thirty nine percent of smokers quit smoking or reduced the smoking amount after increase in tax, among them 28.6% of the smokers (27.9% and 33.0% for males and females, respectively) reported quitting smoking. Female smokers and smokers in preparation stage of Prochaska model reported quitting smoking or reducing the smoking amount than male smokers and smokers in pre-consideration stage (OR 6.85:95% CI=1.78∼26.33, OR 6.62:95% CI= 2.20∼19.95, respectively). Conclusion: Increase of cigarette tax was effective in quitting the smoking and reducing the smoking amount in adolescents in Korea. (J Korean Acad Fam Med 2007;28: 256-262)

Background
: The harmfulness of smoking is well known, but the smoking rate of adult males in Korea is still high. Therefore, we wanted to find out the factors related to smoking cessation among patients who had been admitted to hospital and to make an effective smoking cessation program.

Methods : We reviewed the medical records of patients who had been admitted to the department of internal medicine or orthopedic surgery of an hospital from January 25, 2005 to June 15, 2005. We enrolled 104 male patients who were smokers and gave them telephone interviews. Among them, 74 patients answered (71.2%).

Results : Among the subjects, 10 patients quit smoking and 64 smoked continuously. Age, duration and amount of smoking, past experiences of smoking cessation were not significantly different between the two groups. The patients who were admitted to the department of internal medicine (P=0.047) and advised from doctors to quit smoking (P=0.010) showed a high smoking cessation rate. The patients who were advised by doctors showed a higher rate of planning for smoking cessation, even though they were still smoking (P=0.001).

Conclusion : For smoking cessation in admission patient's, doctor's advice to quit smoking was important.

Background
: It is well-known that a decline in the prevalence of smoking among physicians has preceded a decline in the general population. For the purpose of finding out the reason for lower smoking rate in Korean medical doctors than that of general population whether it is due to knowledge of toxicity related to smoking perceived as health professionals or as the only leader group in society this study was investigated. We selected lawyers as a representative of other professional groups. We investigated smoking rate, habits and attitudes towards smoking in Korean lawyers and compared the smoking rate and attitudes towards smoking in lawyers with those of medical doctors.

Methods : This study investigates smoking rate, habits and attitudes towards smoking in Korean lawyers. An anonymous self-administered postal survey was used. One-third of registered lawyers were sampled according to stratified random sampling. Among 1,401 target population, 463 (38.3%) responded.

Results : Among male lawyers, 38.0% were current smokers, 38.9% were ex-smokers and 23.1% were non-smokers, while 7.7% were ex-smokers and 92.3% were non-smokers among female lawyers. The direct age-adjusted smoking rate among Korean male lawyers was 42.1%.

Conclusion : In comparison of the direct age-adjusted smoking rate among male lawyers, medical doctors and general population in Korea, the rate in lawyers was 42.1%, medical doctors 34.9%, and general population 67.6%. The smoking rate of lawyers was found to be higher than that of medical doctors, but considerably lower than that of general population. In comparison of the attitudes towards smoking between lawyers and medical doctors, the lawyers were found to have a lower level of support in questions of the knowledge about the harmful effects of smoking and smoking bans on health than medical doctors.

Background
: According to recent studies of smoking rates among adolescents, the age at which young people begin to smoke is decreasing. The present study reports the results of a survey, conducted by the Korean National Tuberculosis Association (KNTA) in 2002, of the smoking status of Korean middle school students.

Methods : From April to November 2002, the KNTA surveyed the present smoking status of middle school students (total 14,296: boys-8,697, girls-5,599) according to sex and grade in 125 schools in 12 provinces during a smoking cessation education program.

Results : The survey showed that 18.4% of the males (7th grade-15.8%, 8th grade-17.6%, 9th grade-21.8%) and 8.3% of the females (7th grade-6.2%, 8th grade-9.3%, 9th grade-9.5%) had smoking experience. Approximately 2.5% of the males (7th grade-1.2%, 8th grade-1.8%, 9th grade-4.6%) and 1.0% of the females (7th grade- 0.3%, 8th grade-1.2%, 9th grade-1.5%) smoked regularly. The boys' smoking rate was higher than that of the girls in all grades. Smoking rates varied among the provinces, with Chungbuk having the highest rate (2.8%) and Jeonbuk having the lowest (0.9%). The time when most smokers began to smoke was in 6th grade of elementary school for the boys (15.9%) and 7th grade of middle school for the girls (28.6%). Approximately 69.4% of smokers answered that "curiosity" was the most important motivational factor. Statistical analysis indicated that smoking rates were positively correlated with alcohol use and height of students, but were negatively correlated with parents' level of education. At the end of the smoking cessation education program, the number of smokers had reduced for the boys (from 2.6% to 2.2%), but had increased for the girls (from 1.8% to 2.0%). The pre- program survey on the trans-theoretical stage of smoking cessation revealed that 34.2% fell into a pre- contemplation stage, 34.2% into a contemplation stage, and 31.6% into a preparation stage. The post-education survey showed remarkable changes: 24.0% were in the pre-contemplations stage, 40.0% in the contemplation stage, and 36.0% were in the preparation stage.

Conclusion : This study reports the results of a survey, conducted by the KNTA in 2002, concerning the national smoking status of middle school students, relating factors, and levels of motivation for quitting smoking. The smoking cessation education program run by the KNTA had an impact on the motivational stage of smoking cessation.

Background
: In comparison to the decreasing smoking rate of adults, the smoking rate in adolescents and women is still increasing worldwide including Korea. Previous studies on the smoking rate of adolescents were done by questionnaires allowing bias in their response because of smoking ban among adolescents in Korea. In order to know the actual smoking rate of Korean adolescents, we performed an objective study using urine nicotine detection.

Methods : From April to July 2002, 306 boy's high school students and 325 girl's high school students in Seoul were included for this study. We obtained self-reported questionnaire from them and assessed urine nicotine level by NicCheck I Test Strip to check their actual smoking status.

Results : The current smoking rate of male students by self-reported questionnaire was 14.9%, 20.4%, 22.5%, respectively and that by detection of urine nicotine was 26.6%, 38.0%, 29.6%, respectively, in the 1st, 2nd and 3rd grade. The current smoking rate of female students by self-reported questionnaire was 22.6%, 23.9%, respectively and that by detection of urine nicotine was 46.6%, 35.4%, respectively in the 2nd and 3rd grade. The Kappa index of the questionnaire results was 0.27, 0.46, 0.75, respectively in the 1st, 2nd and 3rd grade male students and 0.33, 0.44, respectively in the 2nd and 3rd grade female students respectively.

Conclusion : The smoking rate of students by detection of urine nicotine was higher than that of the self-reported questionnaire results. The validity of the questionnaire results was more accurate in males than females, and higher grade than lower grade. The self-reported questionnaire was an insufficient tool for evaluation of adolescents' smoking status, especially in female students and lower grade students.

Background
: In spite of worldwide recognition of the hazardous effects of smoking, the adolescent smoking rate in Korea continues to increase. This study was performed to determine the smoking statistics for the Chonan area, and to evaluate the effectiveness of mass smoking cessation education based on Prochaska's trans-theoretical model in adolescents.

Methods : To obtain the smoking statistics, an on-site questionnaire survey was performed on 7,373 students from 5 middle and 6 high schools in the Chonan area from May to July, 2001. A logistic regression analysis was done on the variables in order to determine the factors related to smoking. Immediately after completing smoking cessation education, the second questionnaire, which included questions on the effectiveness and satisfaction of the education, was conducted in one high school.

Results : The smoking rates were 18.0% in males, 8.8% in females; 4.3% in middle school students, and 21.1% in high school students. The smoking rate in vocational high schools (30.7%) was higher than in general high schools (11.9%)(P＜0.001). Multiple logistic regression analyses indicated that the smoking rate increased in males (OR= 2.28), father's smoking status (OR=1.55), mother's smoking status (OR=2.98), and sibling's smoking status (OR=3.57). Approximately 47% of smokers answered that "curiosity" was their most important motivational factor; 29.1% of smokers started smoking in second grade of middle school. The pre-education survey on the trans-theoretical stage of smoking cessation revealed that 38.1% fell into pre-contemplation stage, 36.8% into contemplation stage, and 25.1% into preparation stage. The post-education survey showed remarkable change to 20.8% of pre-contemplations stage, 47.6% of contemplation stage, and 31.6% of preparation stage.

Conclusion : The mass smoking cessation education run by doctors did have an impact on the motivational stage of smoking cessation. Therefore, to improve adolescents' health, an active non-smoking campaign and education should be continued in various ways.

Background
: Despite widespread recognition of the hazardous health effects of smoking, adolescent smoking continues increase, emerging as a public health problem. However few studies have focused on smoking cessation programs for adolescent smokers. The purpose of this study was to measure the short-term effects of adolescent smoking cessation program performed by the Seoul School Health Center.

Methods : Four hundred and twenty adolescent smokers referred from their schools form March to December of 1996 were assessed before and immediately after the program with a self-questionnaire. The data acquired from these 420 students was analyzed.

Results : Males were found to have a higher rate of daily smoking as compared with females. Middle school students had an earlier starting age than those of high school students. About 70% of the students had tried to stop smoking and about 1/3 had a high level of self-efficacy in stop smoking. More than 80% of the students were current alcohol drinkers and 10% ever had experience with other drugs. Many showed poor academic performance and low degree of satisfaction with their schools. More than 50% had experienced punishment at school. Middle and high economic status were more common than low status, 73.3% had smokers in their families and 43.3% showed severe dysfunction in family APGAR. Smoking cessation rate immediately after the program was 37.4%, highest in female high school students and lowest in male high school students. Factors shown to be significantly associated with smoking cessation in males were school age, FTQ scores, presence of peer smokers, smoking and alcohol status, self-efficacy in stop smoking and degree of satisfaction with their schools. School age, presence of peer smokers, smoking and other drug use status, self-efficacy in stop smoking, academic performance, degree of satisfaction with their school, experience of runaway from home, economic status and presence of smokers in their families were significant factors in females. Stepwise logistic regression showed that current alcohol users were less likely to succeed in smoking cessation and those with a higher level of self-efficacy in stop smoking were more likely to succeed in males. In females, high school students with higher economic status were more likely to succeed while those with smokers in their families or experience of runaway from home were less likely to succeed.

Conclusion : To promote smoking cessation, specified and risk-based approaches are considered to encourage the motivation of adolescent smokers. For more effectiveness, programs will need to comprehensively include the school, the family, peers, alcohol and other drug issues as well as smoking problem itself.
