累积生态风险对大学生健康生活方式的影响

Effects of cumulative ecological risk on healthy lifestyle among college students

目的考察累积生态风险对当前和0.5年后健康生活方式的影响效应和作用模式,为促进大学生健康生活方式提供数据支持。方法采用随机整群抽样法,从河北省3所大学大一、大二年级中随机抽取1156名大学生作为被试,采用大学生健康生活方式量表、累积生态风险量表分别于2020年11月与2021年5月进行调查,采用SPSS 24.0统计软件进行分层回归分析。结果累积生态风险对大学生健康生活方式不仅具有横向负向预测效应(β=-0.29,P<0.01),而且具有纵向负向预测效应(β=-0.11,P<0.01)。累积生态风险对大学生健康生活方式的横向预测呈现正加速模式,某一临界点(4个风险数目)之后,健康生活方式水平开始大幅下降;纵向预测呈现线性模式。性别在累积生态风险指数与0.5年后第二次测量健康生活方式之间的线性关系中调节效应无统计学意义(β=-0.02,P>0.05),在累积生态风险与第一次测量当前健康生活方式之间的非线性关系中调节效应有统计学意义(β=0.12,P<0.01)。结论累积生态风险对大学生健康生活方式具有横向和纵向的负向预测效应,其中横向的负向预测效应更高;横向预测的作用模式为正加速模式,纵向预测为线性模式;性别在累积生态风险与健康生活方式之间的横向关系中具有调节效应。

Objective To investigate the effects and patterns of cumulative ecological risk on currrent and 6-month follow-up healthy lifestyle among college students.Methods A total of 1156 freshmen and sophomores students randomly selected from 3 universities in Hebei Province were administered with College Students Health Lifestyle Scale and the Cumulative Ecological Risk Scale in November 2020 and May 2021 respectively.SPSS 24.0 statistical software was used for hierarchical regression analysis.Results Cumulative ecological risk was both negatively associated with current healthy lifestyle(β=-0.29,P<0.01),and healthy lifestyle 6-month after(β=-0.11,P<0.01).The effects of cumulative ecological risks on current healthy lifestyle showed non-linear pattern,with healthy lifestyle rapidly decline after accumulated more than 4 factors.The effects of umulative ecological risks on 6-month follow-up healthy lifestyle showed a linear pattern.No moderating effect of gender was observed in the linear relationship between the cumulative ecological risk and 6-month follow-up healthy lifestyle(β=-0.02,P>0.05),however,significant moderating effects of gender was found in the nonlinear relationship between cumulative ecological risk and current healthy lifestyle(β=0.12,P<0.01).Conclusion Cumulative ecological risk is negatively associated with healthy lifestyle of college students cross-sectionally and longitudinally,in a non-linear and linear association pattern,respectively.Gender plays a moderating effect on the cross-sectional asscociation between cumulative ecological risk and healthy lifestyle.
