Effects of cumulative ecological risk on healthy lifestyle among college students

  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 1 156 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.
