On comprehensive health care system based on semihealth status in school

本研究试图阐明日本初中生亚健康状态的多维结构，并考察其与相关环境因素之间的关系。本研究采用多阶段抽样的方法，选取了540名初中生和604名高中生进行研究。这些自我报告的问卷是在2008年进行的。对符合条件的数据进行主成分分析，提取半健康状态的多维结构。提取了四个主成分作为该结构的复合尺度。特别是，第一主成分可以解释为指示综合半健康状态的半健康指数(SHI)。使用半健康的多维标准对状态进行评估。初中生亚健康状态与课后剧烈体育活动、在家阅读时间、在家看电视时间密切相关。

This study tried to clarify a multidimensional structure of the semihealth status in junior and high schools students in Japan, and to examine the relationship between the status and related environmental factors. The multi-stage sampling method was adopted in order to select the subjects and 540 students in junior high schools and 604 students in high schools were selected for this study. The self-reported questionnaires were administered in 2008. The principal component analyses were performed to the eligible data in order to extract the multidimensional structure of the semihealth status. Four principal components were extracted as compound scales of the structure. Especially, the first principal component could be interpreted as the semihealth index (SHI) indicated synthesis semihealth conditions. Using the multidimensional criteria of the semihealth, the status was assessed. In junior high and high schools students, the semihealth status was closely associated with vigorous physical activities after school lesson, the time of reading at home, and the time of watching television at home.
