我们于1995年4月9日～5月13日对吉林市某中学233名13～16岁少年进行锌营养水平调查。调查结果表明:营养性锌缺乏的发生率为25.75％。应用24小时回顾法进行膳食调查,缺锌组少年只有能量、碳水化合物、维生素B_2达到供给量标准,其他营养素均偏低,其中,蛋白质和锌摄入量与正常组相比具有显著性差异,提示膳食中蛋白质和锌的摄入量不足是导致少年营养性锌缺乏的主要原因。 From April 9 to May 13, 1995, we conducted a survey of zinc nutrition level among 233 children aged 13 to 16 in a secondary school in Jilin City. The survey results show that: the incidence of nutritional zinc deficiency was 25.75%. Dietary survey was conducted by 24-hour retrospective analysis. Only the energy, carbohydrates, and vitamin B 2 in the zinc-deficient group reached the standard of supply while the other nutrients were low. Among them, protein and zinc intake had significant differences compared with the normal group, Suggest dietary protein and zinc intake is inadequate intake of juvenile nutritional zinc deficiency is the main reason.
