背景：食物过敏是一个日益严重的公共卫生问题，特别是在儿童。其发病率在过去十年中有所增加。尽管如此，对实际发病率和患病率的估计是不确定的。本研究的目的是估计食物过敏的婴儿和学龄前儿童的患病率。方法：3897名儿童的父母完成了问卷调查的发生任何反应的食物。家长报告的反应的儿童被选为进一步的检查，包括临床采访，体检，过敏试验，如果必要的话，口服食物挑战，以结束诊断FA.Results：估计患病率过敏的儿童年龄在4-59个月为0.61%，是1.9%的婴儿和0.4%的学龄前儿童。在604名接受家长报告的FA评估的患者中，24名（4%）被确诊为食物过敏，其余580名（96%）被排除在外。其中，大约一半（51/52.6%）的97名婴儿和（128/48%）的487名学龄前儿童已经进行了一段时间的饮食排除怀疑foods.Conclusion：这项研究表明，高的整体患病率的父母目前的食物过敏的信念，但同样的是没有观察到在医生诊断的食物过敏。食物过敏的患病率低于文献中观察到的。这项研究提醒卫生专业人员注意过高估计食物过敏和不必要的饮食排斥病例所带来的风险，这可能导致儿童生长和发育受损，特别是在他们生命的最初几年。(C)2016由Elsevier Espana，S.L.U.出版关于SEICAP
Background: Food allergy is an increasing problem in public health, especially in childhood. Its incidence has increased in the last decade. Despite this, estimates of the actual incidence and prevalence are uncertain. The aim of this study was to estimate the prevalence of food allergy in infants and pre-schoolers.Methods: The parents of 3897 children completed questionnaires on the occurrence of any reaction to food. Children with parentally reported reactions were selected for further examination including a clinical interview, physical examination, allergic tests, and if necessary, oral food challenge to conclude the diagnosis of FA.Results: The estimated prevalence of allergy in children aged 4-59 months was 0.61%, being, 1.9% in infants and 0.4% in pre-schoolers. Among the 604 patients physicians evaluated with parent-reported FA, 24 (4%) had a confirmed diagnosis of food allergy, and 580 (96%) were excluded in the remaining. Of these, approximately half (51/52.6%) of 97 infants and (128/48%) of 487 pre-schoolers already performed the diet exclusion suspected food for a period of time.Conclusion: This study shows that high overall prevalence of parental belief of current food allergy however the same was not observed in the in physician-diagnosed food allergy. The prevalence of food allergy was lower than that observed in the literature. This study alerts health professionals to the risk entailed by overestimation of cases of food allergy and unnecessary dietary exclusion, which may result in impairment in growth and development of children, especially in their first years of life.
