Recently, the oral allergy syndrome (OAS) has been classified according to the foods that induce it: phenotype I, when it is caused only by plant-derived foods; phenotype II, when it is caused by foods of both animal and plant origin.
To determine the prevalence of OAS in late teenagers according to the new classification.
A cross-sectional study in which data from 1,992 teenagers, aged 15-18 year-old, was analyzed; the information was obtained through a structured questionnaire, where questions were asked about oral symptoms according to the type of food that had been ingested.
The overall prevalence of OAS was of 1.7% (95% CI = 1.2-2.4); for phenotype I, it was of 0.85% and, for phenotype II, it was of 0.85%. According to the phenotype, there was no difference by sex and personal history of atopic disease; instead, the onset time of the symptoms did show an association with the phenotype (p = 0.048). The frequency of skin and mucosal symptoms and respiratory ailments differed between the groups. Regarding gastrointestinal symptoms, diarrhea was markedly more frequent in phenotype II (p = 0.044).
Two phenotypes with OAS were clearly identified: the first one was associated exclusively to foods of plant origin, and the other was related to foods of both plant and animal origin.
最近，口腔过敏综合征（OAS）已根据引发该综合征的食物进行分类：I型，仅由植物源性食物引起；II型，由动植物源性食物引起。
根据新分类确定青少年晚期OAS的患病率。
一项横断面研究，分析了1992名15 - 18岁青少年的数据；信息通过结构化问卷获取，问卷询问了根据摄入食物类型的口腔症状。
OAS的总体患病率为1.7%（95%置信区间 = 1.2 - 2.4）；I型为0.85%，II型为0.85%。根据表型，在性别和特应性疾病个人史方面无差异；相反，症状出现时间确实与表型有关联（p = 0.048）。两组在皮肤和黏膜症状及呼吸道疾病的频率上存在差异。关于胃肠道症状，腹泻在II型中明显更频繁（p = 0.044）。
明确鉴定出两种OAS表型：第一种仅与植物源性食物相关，另一种与动植物源性食物相关。
