接触二手烟（SHS）对非吸烟者来说是一种健康风险。室内颗粒物（PM2.5）与SHS暴露相关，并用作替代措施。然而，PM2.5是非特异性的，受许多环境因素的影响，这些因素受到地理变化的影响。SHS暴露和室内PM2.5之间的关联性质-主要在高收入国家（HIC）背景下研究-可能不适用于全球。我们在孟加拉国的达卡的一个低收入/中等收入国家探讨了这种关联。方法采用横断面研究方法，对至少有一名居民吸烟的家庭进行调查。我们询问是否允许在家中吸烟（允许吸烟的家庭，SPH）或不允许吸烟（无烟家庭，SFH），并使用低成本仪器（Dylos DC 1700）测量室内PM2.5浓度至少22小时。我们描述和比较SPH和SFH，并使用多元线性回归来评估哪些变量与所有家庭的PM2.5水平。结果我们在2018年4月至8月期间调查了1746个家庭; 967个（55%）是SPH，779个（45%）是SFH。SFH（中位数27 μ g/m（3），IQR 25）和SPH（中位数32 μ g/m（3），IQR 31）的PM2.5值之间的差异为5 μ g/m（3）（p
Introduction Exposure to secondhand smoke (SHS) is a health risk to non-smokers. Indoor particulate matter (PM2.5) is associated with SHS exposure and is used as a proxy measure. However, PM2.5 is non-specific and influenced by a number of environmental factors, which are subject to geographical variation. The nature of association between SHS exposure and indoor PM2.5-studied primarily in high-income countries (HICs) context-may not be globally applicable. We set out to explore this association in a low/middle-income country setting, Dhaka, Bangladesh. Methods A cross-sectional study was conducted among households with at least one resident smoker. We inquired whether smoking was permitted inside the home (smoking-permitted homes, SPH) or not (smoke-free homes, SFH), and measured indoor PM2.5 concentrations using a low-cost instrument (Dylos DC1700) for at least 22 hours. We describe and compare SPH and SFH and use multiple linear regression to evaluate which variables are associated with PM2.5 level among all households. Results We surveyed 1746 households between April and August 2018; 967 (55%) were SPH and 779 (45%) were SFH. The difference between PM2.5 values for SFH (median 27 mu g/m(3), IQR 25) and SPH (median 32 mu g/m(3), IQR 31) was 5 mu g/m(3) (p
