In developing countries, there is a lack of epidemiological information related to food hypersensitivity, including nuts and seafood.
The aim was to determine the prevalence of allergic reactions and clinical manifestations associated with the consumption of nuts and seeds or seafood in university students.
We designed an observational cross-sectional study. A structured questionnaire was applied to Mexican university students to identify allergic reactions associated with the consumption of nuts and seeds, and seafood.
A sample of 1,200 students was included; mean age of 19.7 ± 1.7 years. Prevalence of symptoms associated with the consumption of nuts and seeds, and seafood were 2.8% (33 of 1,200) and 3.5% (42 of 1,200) respectively. The main clinical manifestations were abdominal pain (63.6% in nuts and seeds), flushing (50% in seafood), and pharyngeal oppression (19% in seafood). Prevalence of perceived, probable and systemic allergy to nuts and seeds was 2.8% (95% confidence interval [CI], 2.5%-3.0%), 0.8% (95% CI, 0.3%-1.3%) and 0.2% (95% CI, 0%-0.4%) respectively. On the other hand, the prevalence (perceived, probable, and systemic) associated with seafood consumption was 3.5% (95% CI, 2.5%-4.5%), 1.8% (95% CI, 1.0%-2.5%), and 0.5% (95% CI, 0.1%-0.9%). Walnut and shrimp were the most frequently reported foods.
For every 100 Mexican university students, approximately 3 or 4 perceived to have allergy attributed to the consumption of some nuts and seeds or seafood, while 1 or 2 students would have a probable reaction to this same type of food. Walnut and shrimp would be causing the higher quantity of food allergic reactions.
在发展中国家，缺乏与食物过敏相关的流行病学信息，包括坚果和海鲜过敏。
旨在确定大学生中与食用坚果、籽类或海鲜相关的过敏反应及临床表现的患病率。
我们设计了一项观察性横断面研究。对墨西哥大学生应用结构化问卷，以识别与食用坚果、籽类及海鲜相关的过敏反应。
纳入了1200名学生样本；平均年龄为19.7±1.7岁。与食用坚果、籽类及海鲜相关症状的患病率分别为2.8%（1200名中的33名）和3.5%（1200名中的42名）。主要临床表现为腹痛（坚果和籽类组为63.6%）、潮红（海鲜组为50%）和咽部压迫感（海鲜组为19%）。对坚果和籽类的感知性、可能的和全身性过敏患病率分别为2.8%（95%置信区间[CI]，2.5%-3.0%）、0.8%（95%CI，0.3%-1.3%）和0.2%（95%CI，0%-0.4%）。另一方面，与食用海鲜相关的（感知性、可能的和全身性）患病率分别为3.5%（95%CI，2.5%-4.5%）、1.8%（95%CI，1.0%-2.5%）和0.5%（95%CI，0.1%-0.9%）。核桃和虾是最常报告的食物。
每100名墨西哥大学生中，约有3或4人被认为对食用某些坚果、籽类或海鲜过敏，而1或2名学生可能会对这类食物产生反应。核桃和虾引发的食物过敏反应数量较多。
