Secondhand smoke (SHS) poses a high health risk to those living in multiunit housing (MUH) since it can easily spread from unit to unit and throughout the building's communal areas. MUH residents in Bangladesh are particularly vulnerable to SHS due to the absence of smoking restrictions within a housing complex. Therefore, this study aimed to assess the prevalence of SHS exposure and its associated factors among MUH residents living in seven divisional cities of Bangladesh- Dhaka, Chattogram, Rajshahi, Khulna, Sylhet, Barishal, and Rangpur.
From April 2019 to November 2019, a cross-sectional survey was conducted with 616 MUH residents aged 18 or older who had been residing in MUH for at least two years in the seven divisional cities of Bangladesh. A multivariable logistic regression model was performed to determine the associated factors of SHS exposure.
In MUH complexes, more than half (54.9%) of the 616 respondents were exposed to SHS. The key factors positively associated with SHS exposure were females (aOR: 1.8, 95% CI:1.236-2.681), residents with a low monthly family income (aOR: 1.9, 95% CI: 1.162-3.220), those whose family members smoked (aOR: 2.4, 95% CI: 1.537-3.746), and Dhaka city residents (aOR: 1.9, 95% CI: 1.013-3.440).
This study revealed a high prevalence of SHS exposure among Bangladeshi MUH residents. Therefore, a smoking ban is needed in and around MUH complexes to protect non-smoking residents from SHS exposure.
二手烟（SHS）对居住在多单元住房（MUH）中的人构成了很高的健康风险，因为它很容易在单元之间以及整个建筑物的公共区域传播。孟加拉国的 MUH 居民由于在住房综合体中没有吸烟限制，因此特别容易受到 SHS 的影响。因此，本研究旨在评估孟加拉国七个行政区城市（达卡、吉大港、拉杰沙希、库尔纳、锡尔赫特、巴里萨尔和朗普尔）居住在 MUH 的居民中 SHS 暴露的流行率及其相关因素。
2019 年 4 月至 11 月，对居住在孟加拉国七个行政区城市的 616 名年龄在 18 岁或以上、在 MUH 居住至少两年的 MUH 居民进行了横断面调查。采用多变量逻辑回归模型确定 SHS 暴露的相关因素。
在 MUH 综合大楼中，超过一半（54.9%）的 616 名受访者暴露于 SHS。与 SHS 暴露呈正相关的主要因素是女性（aOR：1.8，95%CI：1.236-2.681）、月家庭收入低的居民（aOR：1.9，95%CI：1.162-3.220）、家庭成员吸烟的居民（aOR：2.4，95%CI：1.537-3.746）和达卡市居民（aOR：1.9，95%CI：1.013-3.440）。
本研究显示，孟加拉国 MUH 居民中 SHS 暴露的流行率很高。因此，需要在 MUH 综合体内外实施禁烟令，以保护不吸烟的居民免受 SHS 暴露。
