食管癌高低发区居民膳食结构及营养素摄入水平分析

使用３天称重法，分析食管癌高低发区居民膳食结构及营养素摄入水平，结果显示低发区居民膳食结构及营养素摄入水平优于高发区居民。高发区居民豆类、肉类及蔬菜类摄入量明显低于低发区。蔬菜构成中，高发区以浅色蔬菜为主，低发区以深色蔬菜和含大蒜素类蔬菜为主，高发区居民蛋白质数量及质量、锌、钙、ＶＢ２、视黄醇当量较低发区明显缺乏，三大营养素供热比低发区适宜，而高发区碳水化物供热比高达７８．１％，脂肪的供热比偏低，仅为１０．２％，提示膳食结构不合理及营养素摄入水平数量及质量上的差异可能与食管癌的发生与发展有关，为食管癌高发区的病因研究及改善膳食结构和进行营养干预提供依据。

Study on Dietary Pattern and Nutrients Intakes of Residents in Areas of High and Low Incidence of Esophageal Cancer

The dietary pattern and nutrients intakes of residents in areas with high and low prevalence of esophageal cancer were studied by 3 days' dietary survey.The results showed that the dietary pattern and nutrients intakes of residents in areas with low prevalence(ALP) of esophageal cancer was superior to that in area with high prevalence(AHP).The amount of soybean,meat and vegetable consumed by residents in the ALP was more than that in the AHP.Deep color vegetable and gaelic vegetable were dominant in ALP,but so were light color vegetables in AHP.The protein quality and quantity as well as the amount of Zn,Ca,RE and riboflavin consumed in the AHP were lower than that in the ALP.The energy from carbohydrate accounts for 78.14% of the total in the AHP.It is suggested that poor dietary pattern and the quality and amount of nutrients intake may be related to the development of esophageal cancer,and nutrition intervention in area of high prevalence seems rational.
