中国居民微量营养素摄入的地区分布

本文依据１９９２年全国营养调查各省不同年龄居民的膳食情况，详细分析了各省、市、自治区居民微量营养素的摄入情况。分析结果显示烟酸、抗坏血酸和维生素Ｅ的摄入比较充足，大部分省份居民摄入硫胺素、锌和硒较好，而钙、视黄醇当量和核黄素摄入量普遍不足。东北、西北和西南内陆地区是营养素缺乏比较集中的地区。本文分析的结果可以为分区或分省进行微量营养素膳食干预或食物强化提供参考。

Dietary intake of some micronutrients in different provi nces of China

Based on the data collected in 1992 China National Nutrition Survey, which covered 100,201 persons of all ages in 29 provinces, the dietary intakes of some micronutrients were calculated. The intake of calcium, retinal equivalent and riboflavin were the most insufficient nutrients; zinc, selenium and thiamin were close to (80%-90%) of Chinese RDAs. The intakes of niacin, ascorbic acid and vitamin E were sufficient. The regions in the northeast, northwestern and the southeastern inland were more at risk of nutrition deficiency. Dietary intervention or food fortification with some micronutrients could be used for improving the situation.
