【摘要】 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。更多还原

【Abstract】 To estimate the zinc stores in children, hair zinc values were measured in 610 cases with anorexia, growth-development retardation. It showed the incidence of zinc deficiency was 54.4%, mean value of 75.5μg/g was signifi cantly lower than normal value (p<0.001) A proportion of 332 to 273 (82.2%) was preschool-aged children. A positive correlation between the incidence and age was found for the children aged from birth to 3 years of age and an invers correlation between the incidence and the age increase after 4 years old patients with zinc deficiency often demonstrated broad and persistent anorexia, body weight and height significantly lower than those of normal children in their peers. It suggested that zinc deficiency be suspeted if children showed the symptoms. It is necessary to identify the diagnosis and take preventive therapy earlier.更多还原
