对厌食或生长发育不良就诊的610名小儿测发锌研究其营养状况。结果缺锌症患病率为54.4%,均值为75.7μg/g, 显著低于正常值下限111μg/g(P<0.001)。学龄前小儿占全部缺锌症的82.2%。从初生至3岁患病率与年龄增长呈正相关,4岁以后与年龄增长呈负相关。缺锌症患儿有持久性广谱厌食特点,身高和体重非常显著低于同龄相同条件的正常小儿。提示学龄前小儿有上述表现者均应疑似缺锌症,应测发锌以明确诊断,及早采取防治措施。
One hundred and ten children with anorexia or dysplasia were examined for zinc nutrition status. Results The prevalence of zinc deficiency was 54.4% with a mean of 75.7 μg / g, which was significantly lower than the lower limit of normal value of 111 μg / g (P <0.001). Preschool children accounted for 82.2% of all zinc deficiency. The prevalence from birth to age 3 was positively correlated with age, but negatively correlated with age after 4 years of age. Children with zinc deficiency persistent broad-spectrum anorexia characteristics, height and weight were significantly lower than the same age with the same age of normal children. Prompted preschool children have the above performance should be suspected zinc deficiency, zinc should be measured to confirm the diagnosis, as soon as possible to take prevention and treatment measures.
