目的了解某职业技术学院大学生手机依赖的现状及其与身心亚健康的关系。方法采用分层整群抽样方法,对该职业技术学院在校大学生进行一般情况、手机依赖和身心亚健康状况进行调查。结果共调查大学生510人,其中手机依赖发生率为16.86%;独生子女、居住地在城市及月生活费水平越高的大学生手机依赖发生率较高,差异有统计学意义(χ~2=5.98、5.02、7.09;P<0.05);手机依赖组大学生身心亚健康、心理亚健康、及躯体活力不足、情绪问题、社会适应困难三维度得分显著高于非手机依赖组(t=3.68、3.72、3.45、3.29、3.16;P<0.05);多因素非条件logistic回归分析结果显示,身心亚健康、躯体亚健康、心理亚健康均与大学生手机依赖之间存在关联。结论手机依赖在大学生群体中发生率较高,并且与身心亚健康存在关联。 Objective To understand the current situation of mobile phone dependence and its relationship with the sub-health of body and mind in a vocational and technical college. Methods A stratified cluster sampling method was used to investigate the undergraduates’ general conditions, cell phone dependence and the status of physical and mental subhealth in the vocational college. Results A total of 510 college students were surveyed, of which 16.86% were mobile phone dependency. The only children with single children living in cities and with higher monthly living expenses had a higher incidence of mobile phone dependence, with significant differences (χ ~ 2 = 5.98, 5.02, 7.09; P <0.05). The three-dimensional score of college students in mobile phone dependent group was significantly higher than that of non-mobile phone dependent group (t = 3.68, 3.72, 3.45 , 3.29,3.16; P <0.05). The multivariate non-conditional logistic regression analysis showed that there was a correlation between physical and mental sub-health, somatic sub-health and sub-health psychology. Conclusion The dependence of mobile phone on college students is high, and it is related to the sub-health of body and mind.
