目的:分析皮肤点刺试验(skin prick test,SPT)阳性结果,指导家长在喂养过程中控制由食物引起的过敏反应。方法:随机收集2009年6月～2010年10月在南京市妇幼保健院儿保门诊接受健康体检的6个月～2岁儿童195例(排除各种急性期疾病及中、重度湿疹),进行牛奶、鸡蛋、鱼、虾、小麦5种常见食物的SPT,对其阳性结果进行分析。结果:轻微湿疹儿童对食物过敏的有50.75%,正常儿童对食物过敏的有11.47%,轻微湿疹患儿食物过敏发生率高于正常儿童,两者有显著差异(P<0.05)。不同食物过敏原阳性率在各月龄组儿童均表现为鸡蛋>虾>鱼>牛奶>小麦,且随着年龄增长食物过敏阳性率有降低趋势。结论:食物过敏在儿童中发生率较高,尤其是患有轻微湿疹的儿童,根据儿童过敏的特点,应早期避免接触食物过敏原,在辅食添加的过程中逐一添加、循序渐进,从而有效控制食物过敏的发生。 OBJECTIVE: To analyze skin prick test (SPT) -positive results to guide parents in controlling food-induced allergic reactions during feeding. Methods: A total of 195 children aged 6 months to 2 years (excluding acute and chronic eczema and moderate to severe eczema) undergoing physical examination in MCH clinic in Nanjing MCH from June 2009 to October 2010 were collected randomly Milk, eggs, fish, shrimp, wheat five kinds of common food SPT, the positive results were analyzed. Results: The children with mild eczema had 50.75% of food allergy, 11.47% of children with normal food allergy. The incidence of food allergy in children with mild eczema was higher than that of normal children (P <0.05). The positive rate of different food allergens in all age groups showed eggs> shrimp> fish> milk> wheat, and with age, the positive rate of food allergy decreased. Conclusion: The prevalence of food allergy in children is high, especially in children with mild eczema. According to the characteristics of children with allergies, food allergens should be avoided in the early stage. Food allergens should be added step by step during food supplement to control foods effectively Allergy occurs.
