背景：接触二手烟对儿童的健康构成威胁。我们开发了一个以学校为基础的无烟干预（SFI），以支持家庭在孟加拉国实施无烟家庭，并收集其effectiveness.Methods的初步证据：在米尔布尔，达卡内的一个城市地区的24所学校进行了可行性群集随机对照试验的SFI。使用简单分层随机化，学校被分配到：A组（仅SFI），B组（SFI+提醒）和C组（对照组）。共有781名5岁儿童（10-12岁）在同意的学校，参加了这项研究。结果包括“无烟家庭”和“社会可见度”，即不在家里的孩子面前吸烟，通过研究人员在基线和第1周，第12周，第27周和第52周对所有组进行的基于吸烟的儿童调查进行评估。（比值比[OR] = 4.8; 95% CI = 2.6-9.0）和B组（OR = 3.9; 95% CI = 2.0-7.5）相比于C组，当控制基线水平时，第1年。同样，当控制基线水平时，第1年A组（OR = 5.8; 95% CI = 2.8-11.7）和B组（OR = 7.2; 95% CI = 3.3-15.9）的“社会可见度”显著低于C组。我们观察到一个增长的趋势（科克伦阿米蒂奇检验统计量[Z] = 3.8; p <0.0001）随着干预强度的增加，（对照<A组<B组），并且呈下降趋势（Z = -5.13; p <0.0001）在家中的社会可见度。自立扶持计划有可能鼓励儿童在家中争取无烟环境。
Background: Exposure to second-hand smoke is a threat to children's health. We developed a school-based smoke-free intervention (SFI) to support families in implementing smoke-free homes in Bangladesh, and gathered preliminary evidence of its effectiveness.Methods: A feasibility cluster randomized controlled trial of SFI was conducted in 24 schools in Mirpur, an urban area within Dhaka. Using simple stratified randomization, schools were allocated to: Arm A (SFI only), Arm B (SFI plus reminders), and Arm C (the control group). A total of 781 year-5 children (10-12 years old) in the consenting schools, participated in the study. Outcomes including "smoke-free homes" and "social visibility" that is, not smoking in front of children at home were assessed through questionnaire-based children's surveys, administered by researchers, at baseline and at weeks 1, 12, 27, and 52 in all arms.Results: "Smoke-free homes" were significantly higher in Arm A (odds ratio [OR] = 4.8; 95% CI = 2.6-9.0) and in Arm B (OR = 3.9; 95% CI = 2.0-7.5) than in Arm C, when controlled for the baseline levels, at year 1. Similarly, "social visibility" was significantly reduced in Arm A (OR = 5.8; 95% CI = 2.8-11.7) and in Arm B (OR = 7.2; 95% CI = 3.3-15.9) than Arm C, when controlled for the baseline levels, at year 1. We observed an increasing trend (Cochrane Armitage test statistic [Z] = 3.8; p < .0001) in homes becoming smoke-free with increasing intensity of the intervention (control < Arm A < Arm B), and a decreasing trend (Z = -5.13; p < .0001) in social visibility at homes.Conclusion: SFI has the potential to encourage children to negotiate a smoke-free environment in their homes.
