摘　　要：目的了解1991-2009年中国九省区儿童青少年膳食锌的摄入状况、食物来源以及变化趋势。方法利用"中国健康与营养调查"的资料,选取1991、1993、1997、2000、2004、2006和2009年7轮调查中的7～17岁儿童青少年为对象,采用连续3 d 24 h膳食回顾询问法收集膳食资料。结果中国九省区儿童青少年平均每日锌摄入量从1991年的10.4mg下降到2009年的9.1mg。1991年和2009年中国九省区儿童青少年膳食锌摄入量低于平均需要量(EAR)的比例分别为66.6%和79.6%。膳食锌主要来源于谷类食物、动物性食物、坚果和蔬菜水果。结论我国儿童青少年人群中普遍存在锌摄入不足的问题,需要进行适当干预以增加膳食锌摄入量。[营养学报,2013,35(2):131-133]Objective To describe the status and trends of dietary zinc intake, main food sources of zinc among Chinese children from 1991 to 2009. Methods The subjects were selected from the ＇China Health and Nutrition Survey＇ within age group of 7-17 years old. The 24-hour dietary recall method for 3 consecutive days was used to collect food intake information. Results The average daily zinc intake of Chinese children decreased from 10.4mg in 1991 to 9.1mg in 2009. The children with zinc intake less than estimated average requirement （EAR） accounted for 66.6% and 79.6% in 1991 and 2009, respectively. The main food sources of dietary zinc were cereals, animal foods, nuts and vegetables/fruits. Conclusion Low dietary zinc intake was still a problem among Chinese children, and it is necessary to increase dietary zinc intake by nutrition intervention.
