摘　　要：目的探索健康技能在大学生健康知识与健康行为间的中介效应和调节效应。方法采用分层整群随机抽样方法，对2181名长沙市在校大学生进行问卷调查。采用EpiData3．0软件建立数据库，SPSS17．0软件进行相关和回归分析。结果健康知识与健康技能显著相关（r=0．592，P〈0．01），健康知识与健康行为显著相关（r=0．647，P〈0．01），健康技能与健康行为也呈显著相关（r=0．629，P〈0．01）。健康技能在健康知识和健康行为之间的部分中介效应显著（34．55％）。交互作用项“健康技能×健康知识”的回归系数在以健康行为为因变量的回归方程中达到显著性水平（β=-0．093，t=-5．212，P=0．000），且引入交互作用项后新增解释量（△R2）亦达到显著性水平（△R2=0．006，P=0．000），对健康行为变异量的解释增加了0．6％。结论健康技能在大学生健康知识与健康行为间起中介效应和调节效应。Objective To study the influence of mediating/moderating effects of health skills on the relations between health knowledge and health behaviors in college students. Methods Stratified cluster random sampling was used among 2 181 students, selected in several colleges in Changsha, Hunan province. EpiData 3.0 was adopted to establish the database. Correlation and regression analyses were performed by SPSS 17.0. Results Positive correlations were seen on： 1 ） Knowledge and skills on health （r=0.592, P〈0.01 ）, 2） Knowledge and behaviors on health （r= 0.647, P〈0.01）, 3）Health skills and health behaviors （r=0.629, P〈0.01）. The mediating effect of health skills on the relations between health knowledge and health behaviors was significant （34.55%）. The interaction effect of ＂health skill × （times）related knowledge＂ was significant （β =-0.093, t =- 5.212, P = 0.000）. New variables that were produced by the interaction also reached significant level （△R2=0.006, P=0.000）, resulted in increasing the explanation function to health behaviors by 0.6%. Conclusion Health skills could partially mediate the effects and moderate the relationship between health knowledge and health behaviors among college students.
