目的探讨南京市大学生健康危险行为聚集模式及特点,为有效预防健康危险行为的发生提供依据。方法采用随机分层整群抽样方法,选取南京市5所高校3 183名大学生进行自填式匿名问卷调查,采用样本聚类法对12种健康危险行为进行聚类分析。结果男生行为聚集模式分为4组,女生为2组。低危险组男生仅占22.0%,女生占46.6%。2.9%的大学生未发生过任何健康危险行为,其中医学生的比例最高(5.5%);50.9%的大学生发生过≥4种的健康危险行为,艺术专业大学生比例最高(67.6%)。吸烟是女生高危险组的标志性行为。结论大学生健康危险行为聚集方式多样。应根据男、女大学生的聚类特征,分别采取相应的综合干预措施。
Objective To explore the patterns and characteristics of health risk behaviors in college students in Nanjing, and to provide basis for effective prevention of health risk behaviors. Methods A random stratified cluster sampling method was used to select 3 183 college students from 5 universities in Nanjing to conduct self-designed anonymous questionnaire. Clustering analysis was conducted on 12 health risk behaviors using sample clustering. Results There were 4 groups of boys ’behavior aggregation and 2 girls’ groups. Low risk group of boys only 22.0%, girls 46.6%. 2.9% of college students did not have any health risk behavior, among which the highest proportion of medical students (5.5%); 50.9% of college students had more than 4 kinds of health risk behaviors, the highest proportion of art majors (67.6%). Smoking is a hallmark of high-risk girls in girls. Conclusions There are various ways of gathering health risk behaviors among undergraduates. Should be based on the clustering characteristics of male and female students, respectively, to take the appropriate comprehensive interventions.
