ABSTRACT
Tobacco consumption contributes substantially to cardiovascular (CV) diseases, including hypertension. However, the effect of waterpipe (WP) smoking on CV hemodynamics in adolescents is unknown. Thus, the current study investigated the relationship of WP smoking with CV indices in 397 adolescents that included WP only smokers (n = 161) and non-smokers of any other tobacco product (n = 236). CV hemodynamic indices including heart rate (HR), systolic (SBP), and diastolic blood pressures (DBP), mean arterial blood pressure (MAP), pulse pressure (PP), and rate pressure product (RPP) were obtained and calculated for 7th–10th grade students in Irbid, Jordan. After controlling for possible confounding factors, HR, DBP, MAP, and RPP were significantly lower (p < 0.05) in adolescent WP smokers versus non-smokers. Additionally, stepwise regression analyses showed that smoking status can predict (p < 0.001) 5.7% of HR, 6.3% of DBP 7.4% of MAP, and 7.0% RPP. The results indicate that HR and blood pressure are lower in adolescent WP smokers versus non-smokers. Future studies are necessary to verify these findings and understand the mechanism of this effect.
