Little is known about the prevalence and dynamics of smoking habits among university students in Japan, and their association with other lifestyle parameters and biological markers. Data on undergraduate students were here extracted from the questionnaire and laboratory tests of the periodic health checkup of Kyoto University in 2000 and 2001. In addition to simple statistics, longitudinal analyses were performed using logistic regression, and the odds ratio (OR) and its 95% confidence interval (CI) were calculated for each item. Among 11,203 subjects, 12.1% had a smoking habit. The smoking rate was higher in men than in women (14.4% vs 2.4%, P<0.001) and increased from 2.5% (freshmen) to 18.3% (seniors) with advance in year. During one year of follow-up, 5.8% of students newly acquired a smoking habit, and 12.4% of smokers abandoned the habit. Compared with students majoring in natural sciences, the majors in humanities or social sciences were more likely to begin smoking (OR=1.32, 95% CI=1.06-1.65). Taking up smoking was more common among those who consumed alcohol (OR=1.98, 95% Cl=1.56-2.51), and skipped breakfast and dined out more frequently (trend P<0.001 for both), but less common among regular exercisers (OR=0.71, 95% Cl=0.56-0.90). Smoking habits tended to be associated with subsequent proteinuria (adjusted OR=1.39, 95% Cl=0.96-2.00) and subsequent cough or phlegm (adjusted OR=1.56, 95% Cl=0.91-2.67). This study revealed that the proportion of student smokers increases with the year in university, in association with several other lifestyle parameters. Measures should be taken against smoking behavior focusing on freshmen and considering their lifestyle.
关于日本大学生吸烟习惯的流行情况、动态变化以及他们与其他生活方式参数和生物学标志物之间的关联，我们了解得并不多。这里的数据来自于2000年和2001年京都大学定期健康检查的问卷及实验室检测，涉及本科生。除了简单的统计分析外，还使用逻辑回归进行了纵向分析，并计算了每个项目的比值比（OR）及其95%置信区间（CI）。在11203名受试者中，12.1%有吸烟习惯。男性吸烟率高于女性（14.4%对2.4%，P<0.001），且随着年级升高从2.5%（大一学生）升至18.3%（大四学生）。在一年的随访期间，5.8%的学生新养成了吸烟习惯，12.4%的吸烟者戒除了该习惯。与自然科学专业的学生相比，人文或社会科学专业的学生更有可能开始吸烟（OR=1.32，95%CI=1.06 - 1.65）。吸烟在饮酒者（OR=1.98，95%CI=1.56 - 2.51）、经常不吃早餐和外出就餐者中更常见（两者趋势P<0.001），但在经常锻炼者中较少见（OR=0.71，95%CI=0.56 - 0.90）。吸烟习惯往往与随后出现蛋白尿（校正OR=1.39，95%CI=0.96 - 2.00）以及随后咳嗽或咳痰（校正OR=1.56，95%CI=0.91 - 2.67）有关。这项研究表明，随着大学年级升高，学生吸烟者的比例增加，且与其他几个生活方式参数有关联。应针对吸烟行为采取措施，重点关注大一学生并考虑他们的生活方式。
