Who conducted the study?
Dr. Nooshin Yoshany, a researcher in the Department of Health Education and Promotion at Shahid Sadoughi University of Medical Sciences in Yazd, Iran.
Where did they do it?
The study was conducted through Shahid Sadoughi University of Medical Sciences and carried out at four urban comprehensive health centers in Isfahan, Iran.
What did they want to learn?
The researchers wanted to determine whether a structured educational program could improve pregnant women’s knowledge, beliefs, and protective practices related to thirdhand smoke exposure.
How did they perform the study?
The researchers recruited 100 pregnant women from the four selected health centers and randomly assigned them to either an educational intervention group or a control group. Over the course of six weeks, women in the intervention group attended four face-to-face educational sessions about thirdhand smoke, received informational pamphlets, participated in a session with their spouses, and received daily educational messages and support through social media groups, while the control group received routine prenatal care. The researchers then compared participants’ knowledge, beliefs, and protective practices related to thirdhand smoke before and after the intervention.
What did they find?
Compared to pregnant women who received routine prenatal care, pregnant women who participated in the educational program had greater knowledge of thirdhand smoke, stronger beliefs about its health risks, and reported more protective behaviors to reduce exposure. In contrast, the control group showed little to no improvement. This shows that educational interventions can help pregnant women better protect themselves and their developing fetuses from thirdhand smoke exposure.
Why is this study important?
Pregnant women and developing fetuses are especially vulnerable to the harmful effects of tobacco smoke exposure. This study showed that a structured educational program can help pregnant women better understand the risks of thirdhand smoke and adopt behaviors that reduce exposure. By improving knowledge, beliefs, and protective practices, educational interventions may help create healthier home environments and protect both maternal and fetal health. The findings also suggest that incorporating thirdhand smoke education into routine prenatal care could be an effective way to reduce exposure among a high-risk population.
