Abstract
In order to examine the actual condition of smoking, the change of knowledge and attitude on smoking of the male students attending middle and high school in Korea, the surveys were performed twice ranging from 1988 to 1989. The male students in middle and high school were selected by a random sampling method and surveyed by mail. In this survey, the number of classes of middle and high schools in Korea was a sampling unit, and the classes were selected in proportion to each city and each county. The total number of respondents was 3,055 in 1989(1,602 of middle school students, 1,453 of high school students).
The results obtained from the data analysis are as follows;
1. The ratio of smoker in 1989 was 1.5% among middle school students and 32.0% among high school students. The ratio of current smokers and experienced among middle school students has increased from 18.7% to 24.5% and among high school students the ratio has increased by 58.0%. The ratio of smoking among high school students was on the increase significantly as the grade becomes higher. Especially, in the case of third grade high school students, the ratio of smokers who have ever experienced smoking was 72.4%. This result showed that there was little change in the case of middle school students in comparision the first survey(1.8%), while in the case of high school students the ratio has increased by 8.1% in comparision with the first survey(23.9%).
2. With respect to the area, the number of current smokers and experienced among middle and high school students was higher in county then in city. This result showed difference from the first survey in which the number of current smokers and experienced among middle school students was higher in city than in county.
3. In the respect of whether or not there is a smoker among the number of a family, the ratio was 72.3% in middle school students and 75.1% in high school students. This result showed that the ratio of current smoking and the past experience of smoking were significantly higher among the students who had a smoker in their family.
4. In the first survey, the strongest motivation of smoking among middle school students was “from curiosity” and the next was “to join with the friends”while in the second survey the strongest motivation was “from curiosity"(36.4%) and the next was “to release stress”. In the case of high school students strongest motivation in the first survey was “to release stress”(31.0%)，while in the second survey the ratio of “from curiosity”(31.4%) was the highest.
5. The average number of cigarette per day among middle school students was less than 5(60.0%), and this result was same as the first survey. In the case of high school students the average number of cigarettes per day was 6-10 in the first survey, but in the second survey it changed to less than 5(45.9%).
6. The most preferred cigarette among the current smokers was “Eighty-eight”(40.9%) in middle school students, which is same as the first survey. But in the case of high school students the preference tendency has changed from “Sol”(52.2%) to “Eighty-eight(76.0%). The tendency to prefer a foreign cigarette of high school students was significantly higher in cities than in counties.
7. Almost all of the middle and high school students knew about the harmful effect of smoking on health and only 1.2% of middle school students and 2.5% of high school students answered that smoking did not affect our health. In their attitudes on smoking, 79.2% of middle school students and 46.6% of high school students regarded smoking as undesirable behavior, because it can do harm to themselves and other people. This result is almost same as the first survey.
8. Most of current smokers wanted to give up smoking(77.3% of middle school students and 79.1% of high school students) in the same manner as the first survey because of the harmful effect of cigarette smoking on health.

Abstract
A birth cohort analysis was performed in order to investigate trends in the smoking status of Koreans during the past decades. We used the secondary data of the national smoking survey which conducted by the Korean National Tuber¬culosis Association in 1985. The sample consisted of 29,181 people representing the total population over 15 years of age as a result of stratified multi-stage probability sampling.
The results were as follows:
1. The overall prevalence of current smokers over 15 years of age was 61.5% in males and 6.8% in females.
2. The cohort observation revealed important differences in smoking patterns between men and women. The incidence of smoking was highest during the 20-24 age group in all male birth cohorts while the incidence was highest during the 40-49 age group in female birth cohorts. The more recent the birth cohort was, the earlier age smoking began.
3. The smoking prevalence was very low before 20 years of age and it increased sharply during the ages 20-29. The level was maintained after 30 and finally decreased after 50. The lifetime smoking rate was highest among those born from 1951 through 1960 in men, whereas it was highest among those born from 1901-1910 in women.

Abstract
In order to examine the smoking rate, knowlege and attitude on smoking of male students attending middle and high school in Korea a study was performed at the period between July 11 and July 23, 1988.
In each grade 10 classes were sampled and surveyed and the total number of respondents was 3,437.
The results were as follows;
1. Proportion of current smoker among middle school students was less than 3%, but it was increased very rapidly among high school students.
So proportion of smoker was 9.5%, 19.1% and 40.4% among first second and third grade students respectively.
Proportion of ex-smoker was 16.9% among middle school students and 28.1% among high school students.
Proportion of current smoker and ex-smoker were significantly higher among students in city than students in rural area.
2. Proportion of smoker and ex-smoker among students who had smoker in their family were significantly higher than those who had no smoker in their family.
3. Most frequent motivation to smoking was “from curiosity(40.0%)” among smokers in middle school and “to release stress(31.0%)” among smokers in high schools.
4. The proportion of smokers who smoke a cigarette regularly was 31.3% among smokers in middle school and 51.7% among smokers in high school. Sixty percent of smokers in middle school smoked less than 5 cigarettes per day and 76.0% of smokers in high school smoked less than 10 cigarettes per day.
5. Almost all respondents(99.1% in middle school, 98.8% in high school) knew about the harmful effect of cigarette smoking on health and cigarette smoking was regarded as undesirable behavior to 79.5% of middle school students and 49.3% of high school students.
6. Most smokers(63.3% in middle school, 73.8% in high school) wanted to quit smoking due to the harmful effect of cigarette smoking on health.
So family factors were found to be significantly correlated with smoking students. A effective method to release stress and to quit smoking should to be suggested for students.
