Data from a nationwide cross-sectional survey of the smoking status among junior and senior high school students in Japan conducted in 1990, were utilized to provide sociodemographic correlates of the use of cigarettes. The study was based on data from 57, 189 students. The analyses examined the relationship between smoking status and 9 explanatory variables, using multiple logistic regression for both males and females. The results of logistic regression analyses revealed the following main effects: 1) Smoking by a friend had the strongest relationship to smoking status of students for both sexes. The relative risks for having a smoking experience if a friend smoked were 3.45 for junior high school boys, 5.24 for junior high school girls, 3.65 for senior high school boys and 5.54 for senior high school girls and the risks for current smoking if a friend smoked were 8.54, 15.28, 6.99 and 12.47, respectively. 2) Among both boys and girls, smoking experience and current smoking was significantly more likely if a brother or sister, or mother smoked. Awareness of the harm of smoking was also an important correlate in both sexes. Whether the students enjoyed their school life was significantly related to current smoking status for females, but not for males. 3) The relative risks for current smoking if their mothers smoked were 1.60 for junior high school boys, 1.78 for junior high school girls, 1.61 for senior high school boys and 1.61 for senior high school girls. Fathers' smoking was not selected in this stepwise multiple logistic regression model. Therefore, mothers' smoking appears to be a stronger correlate of smoking status among students than fathers' smoking. 4) The relative risks for smoking experience and current smoking if there were smokers in the family, were higher among junior high school students than senior high school students.
利用1990年在日本全国范围内对初中生和高中生吸烟状况进行的横断面调查数据，来提供吸烟行为的社会人口学相关因素。该研究基于57189名学生的数据。分析考察了吸烟状况与9个解释变量之间的关系，对男性和女性均使用多元逻辑回归。逻辑回归分析结果显示了以下主要影响：1）朋友吸烟与学生吸烟状况的关系最为密切。如果朋友吸烟，初中男生有吸烟经历的相对风险为3.45，初中女生为5.24，高中男生为3.65，高中女生为5.54；如果朋友吸烟，当前吸烟的风险分别为8.54、15.28、6.99和12.47。2）在男生和女生中，如果兄弟姐妹或母亲吸烟，吸烟经历和当前吸烟的可能性显著更高。对吸烟危害的认知在两性中也是一个重要的相关因素。学生是否喜欢学校生活与女生当前吸烟状况显著相关，但与男生无关。3）如果母亲吸烟，初中男生当前吸烟的相对风险为1.60，初中女生为1.78，高中男生为1.61，高中女生为1.61。在这个逐步多元逻辑回归模型中未选中父亲吸烟这一因素。因此，母亲吸烟似乎比父亲吸烟与学生吸烟状况的相关性更强。4）如果家庭中有吸烟者，初中学生吸烟经历和当前吸烟的相对风险高于高中学生。
