目的运用典型相关方法从多维度探讨几组中国青少年健康行为之间的相互关系。方法数据来自2003年全球学校学生健康状况调查——中国区(GSHS)。健康行为变量分为四组:健康行为、心理、其他个人行为和环境行为组。典型相关分析以SPSS13.0完成。结果不良心理状态主要由高水平的孤独、焦虑、有自杀想法、有自杀计划和抑郁来反映,健康行为主要由少吸烟、少饮酒、较少静坐行为和经常吃早餐来反映,其他不健康个人行为包括较少安全带使用、参与斗殴和旷课,而不良环境行为由较多被欺负、受到严重伤害和他人在面前吸烟决定。处于不良心理状态个体发生不健康行为的可能性越大,而暴露于不良环境行为越多者,其心理风险也越大。结论行为是一种多元变量,没有一个或一组心理或其他行为变量能够单独影响和解释中国青少年的健康行为。在进行这类因素的关联分析时,可更多地考虑应用典型相关分析方法。
Objective To explore the interrelationship between groups of healthy behaviors of adolescents in China from multiple perspectives by using typical correlation methods. Methodological data from the 2003 Global School Student Health Survey - China (GSHS). Health behavior variables are divided into four groups: healthy behavior, psychology, other personal behavior and environmental behavior group. Canonical correlation analysis was done with SPSS 13.0. Results The adverse psychological state was mainly reflected by a high level of loneliness, anxiety, suicidal thoughts, suicide plan and depression. The main health behaviors were smoking, drinking less, sitting less and eating breakfast regularly, other unhealthy behaviors Including fewer seat belt use, fighting and absenteeism, and poor environmental behavior being more bullied, severely harmed and smoking in front of others. In unhealthy state, individuals are more likely to have unhealthy behavior, while those who are exposed to adverse environment are more likely to have psychological risk. Conclusions Behavior is a multivariate variable, and no single or group of psychological or other behavioral variables can individually influence and explain the health behaviors of Chinese adolescents. In the correlation analysis of such factors, more consideration can be given to the use of canonical correlation analysis.
