廣州市青少年食物攝入情況:與中國居民膳食指南的比較

摘要


食物類別攝入情况與青少年健康密切相關,目前爲止,尚無研究評估中國青少年的食物類別攝入情况。目的:瞭解居住在廣州市的青少年食物類別攝入情况,幷評價其是否達到中國居民膳食指南和中國居民平衡膳食寶塔(2007)推薦的攝入量。方法:2006年10月到2007年4月期間,在廣州市開展了一項以學校爲基礎的橫斷面研究。隨機調查了2977名年齡在12-17歲的青少年,采用自填式的半定量食物頻數問卷來估計青少年的食物攝入情况,幷根據中國居民平衡膳食寶塔(2007)推薦的食物種類,將食物分爲糧穀類、蔬菜、水果、畜禽肉類、魚蝦類、蛋類、奶製品、豆製品及堅果類八大類。結果:大部分青少年植物性食物如蔬菜、水果和豆製品的攝入量較低,僅有9%、14%和6%的青少年蔬菜、水果、豆製品和堅果類的攝入量達到推薦的最低攝入量。接近70%的青少年奶製品攝入量低于推薦攝入量,25.2%的青少年糧穀類和蛋類的攝入量達到推薦攝入量。35.6%的青少年沒有一種食物類別的攝入量達到推薦攝入量。沒有一個研究對象滿足所有八類食物的推薦攝入量。此外,鈣和鐵的攝入量不足也在青少年中常見。結論:本次研究調查的青少年,大部分食物類別未能達到中國居民膳食指南推薦的攝入量。
