Several studies reported inconsistent associations between using gas for cooking and respiratory symptoms or lung function in children. Kitchen ventilation characteristics may modify the relationship between gas cooking and respiratory health. The aim of this study was to investigate the effect of kitchen ventilation (while cooking) on the relationship between gas cooking, combustion product dispersal, and respiratory and allergic outcomes in children.
Data on respiratory and allergic symptoms and diagnoses were collected by yearly questionnaires in a population of over 3000 children participating in a birth cohort study on development of allergy and asthma. At 4 years of age, a sub-sample of 647 children provided blood samples for antibody testing. Data on gas cooking and kitchen ventilation were collected when the children were 5 years old. Based on these data a model was constructed to determine the chance of accumulation of combustion products (CACP) in the kitchen.
No relationship was found between gas cooking and any of the respiratory or allergy outcomes except nasal symptoms. The overall results did not change when the 'CACP' was used as exposure variable instead, while the association for nasal symptoms decreased to borderline significance.
Our results suggest that gas cooking per se is associated with nasal symptoms in young children and not with the other respiratory symptoms that were investigated. Taking kitchen ventilation characteristics into account did not lead to different conclusions in this population where, according to the classification system, the majority of households using gas for cooking have insufficient kitchen ventilation.
多项研究报告了儿童使用燃气烹饪与呼吸道症状或肺功能之间的关联不一致。厨房通风特性可能会改变燃气烹饪与呼吸健康之间的关系。本研究的目的是调查（烹饪时）厨房通风对儿童燃气烹饪、燃烧产物扩散以及呼吸和过敏结局之间关系的影响。
通过年度问卷收集了3000多名参与过敏和哮喘发展出生队列研究的儿童的呼吸道和过敏症状及诊断数据。在4岁时，647名儿童的子样本提供了血液样本用于抗体检测。在儿童5岁时收集了燃气烹饪和厨房通风的数据。基于这些数据构建了一个模型，以确定厨房中燃烧产物积累的可能性（CACP）。
除鼻部症状外，未发现燃气烹饪与任何呼吸道或过敏结局之间存在关联。当将“CACP”用作暴露变量时，总体结果没有变化，而鼻部症状的关联降至临界显著水平。
我们的结果表明，燃气烹饪本身与幼儿的鼻部症状有关，而与所调查的其他呼吸道症状无关。在该人群中，考虑厨房通风特性并未得出不同结论，根据分类系统，大多数使用燃气烹饪的家庭厨房通风不足。
