Introduction: Exposure to passive smoking contributes to a worldwide burden of disease, not only in 
adults but also in children. Children exposed to passive smoking have a major risk factor on their 
health, as tobacco smoke contains more than 4000 chemical substances. Patients and methods: The 
medical records of 150 children were reviewed for a full history taking and clinical examination with 
special concern to blood pressure measurements. Results: There was insignificant statistical differences 
between exposed and non-exposed children regarding sociodemographic and clinical data (p>0.05).
Conclusion: The socio-demographic data did not show significant differences between children exposed 
to passive smoking when compared to children who were not-exposed to passive smoking.
