To study the effect smoking for physical development. 309 of the third: year if boys senior high school students around Nonson area were randomly selected were given the questioners and we´s asked to submit their physical examination records from the age of 7(elementary school) to 17(second year in senior high school). The relationship between the smoking and reduced height or weight of the students were examined.
The conclusions obtained from this study were as follows:
1. The average heights of the students in the nonsmoking group at the age of 12 and 13 were 147.9±7.1cm and 155.4±7.4cm respectively, and those of the students who smoked for under two years were 145.7±7.2 cm and 152.5±8.3 cm respectively. It was show that the average heights of the students at the ages of 12 and 13 were smaller in the smoking group and this difference was statistically significant(p>0.05). However, at other ages, there was no significant differences in the height between the two groups.
2. The average weight of the students in the nonsmoking group at the age of 13 was 43.8±7 kg and that of the group who smoked for under two years was 41.2±6.9kg. This lower value in the smoking group is statistically significant(p>0.05). But in the group who smoked for more than five years. The average weights at the ages of 14,15, and 16 were 52.4 ± 8.9 kg, 57.2 ± 8.0 kg and 60.6 ± 8.7 kg respectively and these values were higher than J the corresponding values 50.7 ± 8.7 kg, 56.4 ± 8.4 kg, and 59.1 ± 7.7 kg, of the nonsmoking students. However these lower value in nonsmoking group was not statistically significant.
3. The relationships between the height and he weight. The amount and the length of smoking and the weight and the length of smoking were examined at the age of 17.
The values were 0.4941, 0.4971(p<0.01) and 0.1966(p<0.05) respectively and the relationship in each case was shown to be normal. However, the values between the height and the amount of smoking. The height and the length of smoking and the weight and the amount of smoking were 0.0183.. 0.1274 and 0.1704 respectively, and there was no significant relationships between these values.
4. When the average height and weight of the students at the age of 17 were compared according to the their parents job, medicare insurance fee, and the habit of eating and smoking, there was no significant difference between the values of the nonsmoking and smoking group.
5. When the complications of the smoking were examined. the coughing and asthmatic pain was the most prominent one(0.6049?0.4) and dizziness(0.2927?0.4). difficulty in breathing(0.2146±0.4), and shaking of hands(0.1951?0.3) ,were next common complications. The coughing and asthmatic pain was show to be highest in the group who smoked for under two years(0.7463?0.4), high in the group who smoked for less than one year(0.4667? 0.5). These values were statistically significant. But in the case of the other complications, there was no significant values.
This the above results suggest that there seems to be no significant deleterious effects of smoking on the development of heights and weight of youngsters at their early ages. But it is likely that if the length of smoking is extended toward the middle age of their lives, the effects of smoking on their health could be more serious at their later stage of lives.
