我们报告的二手烟（SHS）暴露的基础上唾液可替宁水平的儿童在孟加拉国-一个国家的法律，禁止在公共场所吸烟。2015年对达卡地区两个地区的小学生进行了调查。参与者完成了一份问卷，并提供了唾液样本用于可替宁测量，以评估SHS暴露，临界值范围≥ 0.1 ng/mL。从12所小学招募了481名五年级学生。其中，479份唾液样本被发现足以进行可替宁检测，其中95%（453/479）的样本对最近的SHS暴露呈阳性。几何平均可替宁为0.36（95% CI = 0.32 - 0.40）; 43%（208/479）的儿童与至少一名吸烟者同住。只有21%（100/479）的居民和游客报告了完全的吸烟限制; 87%（419/479）还报告最近在公共场所暴露于SHS。与吸烟者一起生活和附近烟草销售商店的数量与最近的SHS暴露呈正相关。尽管禁止在公共场所吸烟，但孟加拉国儿童最近的SHS暴露仍然很高。迫切需要减少孟加拉国儿童接触SHS。儿童由于暴露于SHS而承受的疾病负担比任何其他年龄组都大。然而，近年来，生活在许多高收入国家的儿童接触SHS的情况急剧下降。目前尚不清楚的是，生活在低收入国家的儿童是否仍然暴露于SHS。我们的研究表明，尽管在公共场所禁止吸烟，但孟加拉国达卡的大多数小学生仍然可能暴露于SHS。
We report on second-hand smoke (SHS) exposure based on saliva cotinine levels among children in Bangladesh—a country with laws against smoking in public places. A survey of primary school children from two areas of the Dhaka district was conducted in 2015. Participants completed a questionnaire and provided saliva samples for cotinine measurement to assess SHS exposure with a cut-off range of ≥0.1ng/mL. Four hundred and eighty-one children studying in year-5 were recruited from 12 primary schools. Of these, 479 saliva samples were found sufficient for cotinine testing, of which 95% (453/479) were positive for recent SHS exposure. Geometric mean cotinine was 0.36 (95% CI = 0.32 to 0.40); 43% (208/479) of children lived with at least one smoker in the household. Only 21% (100/479) reported complete smoking restrictions for residents and visitors; 87% (419/479) also reported being recently exposed to SHS in public spaces. Living with a smoker and number of tobacco selling shops in the neighborhood had positive associations with recent SHS exposure. Despite having a ban on smoking in public places, recent SHS exposure among children in Bangladesh remains very high. There is an urgent need to reduce exposure to SHS in Bangladeshi children. Children bear the biggest burden of disease due to SHS exposure than any other age group. However, children living in many high-income countries have had a sharp decline in their exposure to SHS in recent years. What remains unknown is if children living in low-income countries are still exposed to SHS. Our study suggests that despite having a ban on smoking in public places, most primary school children in Dhaka, Bangladesh are still likely to be exposed to SHS.
