研究目的 - 为了研究被动接触烟草烟雾和气体在家里呼吸道症状和非吸烟妇女的肺功能烹饪效果。设置 - 对被动吸烟和暴露于从气体对成年人的呼吸健康烹饪二氧化氮的影响的证据是有限的，可变的。超过97％的女性在新加坡不吸烟，室内空气污染的家庭主妇的主要来源是被动吸烟和天然气做饭。设计 - 这是一个横截面（流行）的2868名成人年龄在20岁至74岁的新加坡人口基础样本的研究。由经过培训的调查员管理的结构化问卷，对被动吸烟，气体烹饪，呼吸道症状，以及其他相关变量收集数据。被动吸烟定义为暴露于香烟烟雾从谁曾经吸烟家庭的一个或多个成员。燃气烹饪在燃气烹饪的每周频率，以及与被申请人的厨房里弥漫着沉重的油烟（很少，偶尔，经常）的频率来定义的。在一秒（FEV1）用力呼气体积通过使用便携式微肺活量计测量。多变量分析用来估计关联的相对比值为呼吸道症状和FEV1作用，具有调整潜在混杂变量。参与者 - 样品中共有1438名女性中，有1282周谁的妇女从未吸烟提供调查问卷的数据和1008名妇女进行分析提供了可接受的FEV1的读数。 MAIN RESULTS--Passive smoking was significantly associated with greater relative odds of usual or chronic cough and phlegm, wheezing, and breathlessness on exertion, as well as lower FEV1. Greater relative odds of respiratory symptoms were also associated with the weekly frequency of gas cooking, although these results were statistically insignificant. Chronic cough and phlegm and breathlessness on exertion, however, were significantly associated with the frequency with which the kitchen was filled with heavy cooking fumes. A lower FEV1 was found in women who cooked frequently (more than thrice a week). CONCLUSION--Domestic exposure to cigarette smoke and gas cooking is associated with increased risks of respiratory symptoms and impairment of lung function in non-smoking women in Singapore.
