Predictors of parental knowledge of tobacco effects on health and parental perceptions on tobacco control measures at household level in selected urban residential areas of Dhaka city, Bangladesh

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.
