对903例人群食物不耐受相关症状调查分析

Food intolerance-related symptoms in 903 individuals

目的对903例人群食物不耐受相关症状及其影响凶素进行分析。方法用酶联免疫方法（ELISA）检测人血清中14种食物过敏原特异性IgG抗体。同时采用食物不耐受检测健康状况评估表收集食物不耐受阳性情况、饮食习惯等方面资料。采用SPSSFORWINDOWS13．0软件对相关资料进行频数分析、卡方检验、Mann—Whitney检验等。以P〈0．05为差异有统计学意义。结果食物不耐受发牛频率前五位依次是：蟹（254例，占28．13％）、蛋清／蛋黄（244例，占27．02％）、牛奶（118例，占13．07％）、大豆（108例，占11．96％）。不同患者可出现1种到8种食物不耐受。食物不耐受者症状出现频率依次为神经系统（55．89％）、消化道（45．69％）、心血管系统症状（15．64％）。脑力劳动者发生食物不耐受低于体力劳动者（P〈0．05）。结论人群对食物不耐受最常见的食物为：蟹、蛋清／蛋黄和牛奶。不耐受的症状可表现在多个系统。多见于体力劳动者。

Objective To investigate the symptoms and affecting factors of food intolerance among 903 adults. Methods Food special antibody （IgG） in human serum were examined by ELISA. Food Intolerance Health Assessment Questionnaire was used to assess positive rate of food intolerance and food intake habits. Chi-square test and Mann-Whitney test were used for data analysis. Results The ratio of food intolerance was 0. 33% to 28. 13% . Intolerant foods include crab （ 28. 13% ）, yolk （ 27.02% ）, milk （ 13.07% ）, soybean （ 11.96% ）, shrimp, tomato, corn, beef, rice, chicken, musbroom, wheat, and pork. The symptoms of nervous system （55.89%）, digestive system （45.69%） and respiratory system （ 15.64% ） were commonly seen. Prevalence of food intolerance in mental labors was lower than manual labors. Conclusion The most common intolerant food includes crab, yolk and milk. The symptoms of food intolerance are different. Manual labors are more susceptible to food intolerance.
