影响中国青少年亚健康相关因素的系统评价

目的系统评价影响中国青少年亚健康状况的相关因素。方法计算机检索CBM、VIP、CNKI和wanFangData中截至2012年5月发表的中文文献，纳入已发表的关于中国青少年学生亚健康状况的研究文献。由两名研究者独立进行文献筛选、资料提取并交叉核对后，采用定性研究方法进行归纳与分析。结果按照纳入与排除标准最终纳入41篇横断面研究。定性分析结果显示：依据不同的影响因素进行分类归纳，可将影响我国青少年亚健康状况的相关因素分为社会因素、家庭因素、学校因素、个人因素4大方面，其中主要影响因素包括社会支持、就业压力、家庭经济条件、学习压力、同伴关系、不良的生活行为习惯等。结论我国青少年学生亚健康状况的影响因素众多且交互作用。由于纳入研究均为描述性研究，文献质量不高，因果论证效能较低，期待更多前瞻性队列研究提供高质量证据。

Methods We electronically searched the following four databases including CBM, VIP, CNKI and WanFang Data to collect Chinese literature on adolescent sub-health status and problems in China published before May 2012. Two reviewers independently screened literature, extracted data, and cross checked records. Then qualitative analysis was applied.

The results of qualitative analysis showed that the influencing factors of adolescent sub-health could be classified into four categories including social factors, family factors, school factors, and interpersonal relationships. The main ones were social support, employment pressure, family economic conditions, learning burden, unhealthy habits, etc. Conclusions There are many influencing factors of adolescent sub-health with interaction.
