The study aimed to investigate parental knowledge of tobacco effects on health and parental perceptions on tobacco control measures at households in Dhaka city, Bangladesh. Out of 1436 tobacco-using parents, a total of 400 participants were selected for the cross-sectional survey using a multi-stage probability sampling. Overall knowledge and perceptions of parents were scored. Simple and multiple logistic regressions were performed. There were 19.8% of parents who had good knowledge about health effects of tobacco and 40.8% had positive perception on home initiatives of tobacco control measures respectively. The study revealed that knowledge of overall tobacco effects on health (AOR = 20.92, 95% CI = 2.60-167.83), asthma (AOR = 0.29, 95% CI = 0.17-0.49), infertility (AOR = 0.43, 95% CI = 0.24-0.77) and pre-eclampsia (AOR = 0.36, 95% CI = 0.14-0.90) were significantly increased the odds of parents good knowledge. Whereas, parental perceptions indicate that living in the joint family was positively associated with controlling tobacco use (AOR =3.10, 95% CI = 1.88-5.13). It suggests that health education programs need to be developed to improve parental awareness on the adverse health effects of tobacco-use at households.

在孟加拉国达卡市选定的城市居民区，父母对烟草对健康影响的了解和父母对家庭层面烟草控制措施的看法的预测因子

该研究旨在调查孟加拉国达卡市家庭中父母对烟草对健康影响的了解以及父母对烟草控制措施的看法。在 1436 名使用烟草的父母中，共有 400 名参与者被选择用于使用多阶段概率抽样的横断面调查。对父母的整体知识和看法进行评分。进行了简单和多元逻辑回归。分别有 19.8% 的家长对烟草对健康的影响有良好的认识，40.8% 的家长对家庭控烟措施持积极态度。研究表明，了解烟草对健康的总体影响（AOR = 20.92, 95% CI = 2.60-167.83）、哮喘（AOR = 0.29, 95% CI = 0.17-0.49）、不孕症（AOR = 0.43, 95% CI = 0.24-0.77) 和先兆子痫 (AOR = 0.36, 95% CI = 0.14-0。90) 显着增加父母良好知识的几率。然而，父母的看法表明，共同生活与控制烟草使用呈正相关（AOR = 3.10，95% CI = 1.88-5.13）。它建议需要制定健康教育计划，以提高父母对家庭使用烟草对健康的不利影响的认识。
