【摘要】：目的了解北京市四季青學區(qū)小學生的膳食營養(yǎng)狀況,為指導(dǎo)學生養(yǎng)成科學的膳食行為提供參考。方法選擇北京市海淀區(qū)四季青學區(qū)8所小學7~13歲的二~五年級1 436名學生為研究對象,進行3 d的24 h回顧性膳食問卷調(diào)查。結(jié)果 11~13歲組男、女生平均每日能量攝入量分別占推薦值的87.6%和88.8%,女生平均每日蛋白質(zhì)攝入量占推薦值的87.2%;其余各年齡組男、女生平均每日能量和蛋白質(zhì)攝入量基本達到推薦值水平。膳食能量來源中,碳水化合物供能比例為40.8%,低于參考范圍下限;而脂肪供能比例為45.6%,高于參考范圍上限。各年齡組營養(yǎng)素平均每日攝入量除了鐵、維生素E達到推薦值外,鈣、鋅、維生素A、維生素C平均每日攝入量均小于推薦值,分別占推薦值的38.8%~61.3%,67.6%~90.0%,51.1%~92.5%,10.2%~18.5%。一日三餐早餐、午餐、晚餐的供能比例分別為26.2%,34.8%,29.8%,基本合理。結(jié)論北京市四季青學區(qū)小學生膳食結(jié)構(gòu)不合理,營養(yǎng)素攝入不均衡。建議學校加強對學生的相關(guān)營養(yǎng)教育,保證學校營養(yǎng)午餐的質(zhì)量,并加強與家長聯(lián)系,改善學生在家中膳食營養(yǎng)。
