現階段的孩童，由於少子化造成家長過於保護，無形中減少了許多讓孩子活動的機會；如果加上從小飲食習慣不良，將導致慢性疾病提早到來，嚴重威脅其健康。本研究主要討論苗栗縣國小學童生活型態與體位之相關研究。以苗栗縣國小103學年度應屆畢業學生為研究母群體，採分層比例隨機抽樣方式。利用自編結構式問卷進行資料蒐集，取得有效問卷358份，回收率為88.7%。以SPSS套裝統計軟體進行描述性統計、單因子變異數分析、徑路模式分析等方法進行分析。本研究主要的發現有:學童的生活型態皆屬正向，其中學童的生活型態與父母的運動習慣及父母從事休閒活動類型有顯著相關，除飲食習慣外，運動與休閒行為、體重控制態度、體重控制行為皆為體位之觀察指標。透過研究發現建議立法將垃圾食品廣告管理規範列入相關的廣播電視廣告製播標準，降低兒童接收此類廣告的機會、加強學生運動與休閒的型態，減少其靜態休閒的時間、落實健康教育，建立學校與家庭共同努力的模式。
