In a study of about 7000 children, parents' perceptions were used to examine the prevalence of food intolerance, the types of food implicated, the association of intolerance with diseases, and the social background of those identified as being food intolerant. One hundred and ninety two children (3%) were perceived as being food intolerant, with a further 105 (2%) being classed as intolerant under a less stringent definition of intolerance. For 128 (67%) of these children a doctor was consulted. The pattern of food avoided was very similar in children for whom the decision to exclude certain foods was made by health staff and in those for whom the parents themselves made decisions about their child's diet. A strong association was seen between the mother's level of education and the child being perceived as being food intolerant. Between 20% and 30% of children with a disease associated with food intolerance--for example, eczema--had currently or previously avoided some types of food. The results of this study emphasise the need to develop criteria to tackle the growing demand for National Health Service treatment by parents who believe their child to be food intolerant.
在一项针对约7000名儿童的研究中，通过家长的认知来调查食物不耐受的发生率、涉及的食物种类、不耐受与疾病的关联，以及被认定为食物不耐受儿童的社会背景。192名儿童（3%）被认为存在食物不耐受，另有105名儿童（2%）在对不耐受定义较宽松的情况下被归类为不耐受。其中128名儿童（67%）咨询过医生。在由医护人员决定排除某些食物的儿童和由家长自行决定孩子饮食的儿童中，避免食用的食物模式非常相似。母亲的教育水平与孩子被认为存在食物不耐受之间存在很强的关联。患有与食物不耐受相关疾病（如湿疹）的儿童中，有20%至30%目前或之前避免食用某些类型的食物。这项研究的结果强调，需要制定标准，以应对那些认为自己孩子存在食物不耐受的家长对国民医疗服务体系治疗需求不断增加的情况。
