Food group intake in adolescents has many health implications. However, no study has been conducted to assess food group intake among Chinese adolescents.
The purpose of this study was to evaluate food group intakes among Chinese adolescents living in Guangzhou city and the proportion of adolescents surveyed meeting the Chinese dietary guidelines, and the Chinese food pagoda for a balanced diet 2007.
A school-based cross-sectional survey was conducted in Guangzhou city between October 2006 and April 2007. A random sample of 2977 adolescents, aged 12 to 17 years, was interviewed. A self-administered semi-quantitative food frequency questionnaire was used to estimate food group intakes of adolescents.
A high percentage of adolescents consumed too little plant foods including vegetables, fruit, and soybean products. Only 9%, 14% and 6% of adolescents surveyed reached the minimum daily recommended intake levels for vegetables, fruit, and soybean products and nuts. Nearly 70% of the studied adolescents consumed dairy less than the recommended daily intake and more than 20% adolescents reached the recommended amounts for cereals and eggs. More than one-third (35.6%) of adolescents did not meet any food group recommendations. And no adolescents reached all eight food group recommendations. An inadequate consumption of calcium and iron among adolescents was also found.
The results of this study indicate that most adolescents living in Guangzhou city are not meeting the current recommendations for intakes of the various food groups.
青少年的食物组摄入量对健康有诸多影响。然而，尚未有研究评估中国青少年的食物组摄入量。
本研究旨在评估居住在广州市的中国青少年的食物组摄入量，以及被调查青少年符合中国膳食指南和《中国居民膳食宝塔（2007）》的比例。
2006年10月至2007年4月在广州市开展了一项基于学校的横断面调查。对2977名12至17岁的青少年进行了随机抽样访谈。使用一份自填式半定量食物频率问卷来估计青少年的食物组摄入量。
很大比例的青少年植物性食物摄入量过少，包括蔬菜、水果和豆制品。在被调查的青少年中，只有9%、14%和6%的人达到了蔬菜、水果以及豆制品和坚果的每日最低推荐摄入量水平。近70%的被研究青少年乳制品摄入量低于推荐的每日摄入量，超过20%的青少年谷类和蛋类摄入量达到推荐量。超过三分之一（35.6%）的青少年未达到任何食物组的推荐摄入量。而且没有青少年达到所有八个食物组的推荐摄入量。还发现青少年钙和铁的摄入量不足。
本研究结果表明，大多数居住在广州市的青少年未达到目前各类食物组摄入量的推荐标准。
