目的 分析无锡市新吴区中小学生视力状况与不同学习阶段视力不良程度的关系,为掌握基线值及后续采取干预措施提供理论基础.方法 收集2018-09/2019-06无锡市新吴区小学、初中、高中共计49322人的健康体检数据,通过卡方检验、Kruskal-Wallis H检验、Mantel-Haenszel卡方检验分析学生在不同学习阶段的视力不良率、学生在不同学习阶段的近视程度的差异以及随年级增加视力不良程度情况.结果 中小学视力不良检出率62.25％,且存在学习阶段、近视程度、性别的差异.从不同学习阶段来看,小学生视力不良检出率54.27％,初中学生视力不良检出率85.67％,高中学生视力不良检出率96.13％,不同学习阶段视力不良率差异有统计学意义(P＜0.001);从不同近视程度来看,小学至高中阶段,随着年级增加,视力不良严重程度加重,差异均有统计学意义(P＜ 0.001);从不同性别来看,小学、初中阶段男生视力不良率低于女生,差异有统计学意义(P＜ 0.001;P＜0.001).结论 随着青少年儿童的年级增加,高年级视力不良检出率越高.此外高年级重度视力不良构成比明显增高,表明青少年儿童的用眼保护工作应加强和重视.

为调查在校大学生微商创业的方法、途径，收获与面临的问题，并对此提出可行性建议。我们通过问卷抽样调查的方式对南充三高校大学生进行调查。被调查大学生中是微商的占6.39%，不是微商的占93.61%，在不是微商的大学生中有19.02%有确定要做微商的想法。同时在微商创业过程中容易遇到一系列问题，如上当受骗，刷跑朋友，影响学习等。因此，我们针对这些问题提出一些可行性建议，让大学生正确迈出创业步伐，从微商创业中收获更多的自主创业经验，同时为新时代国家创新型人才的培养奠定基础。

Objective To investigate the current status of health literacy among college students and its influencing factors,and to provide a basis for developing targeted health-related work in future. Methods The questionnaire was designed on the basis of 66 Health Literacy Questionnaire of Chinese Citizens.Stratified cluster sampling was adopted and 1,000 undergraduates in Nanchong were chosen randomly as the research objects. Results The rate of health literacy of college students in Nanchong was 9.83%.Medical students' health literacy level was higher than that of non-medical students(χ2=52.529,P0.05).The senior students' health literacy level was higher than that of the junior students(χ2=28.604,P0.05). Conclusions The overall level of college students' health literacy in Nanchong is low,and the enhancement of health literacy is primarily related to the accumulation of medical knowledge.So all colleges and universities,particularly non-medical institutions,should incorporate health literacy training into education,pay attention to the cultivation of healthy life style and behaviors of university students,and increase the level of health literacy of college students.
