Abstract
Background: Tobacco consumption adversely affects cardiovascular (CV) disease (CVD) and risk profile, including hypertension. The long-term effect of cigarette smoking on blood pressure (BP) in adolescents is still, however, equivocal. Thus, the current study examined the CV hemodynamics in male adolescent cigarette smokers versus non-smokers.
Methods: Resting heart rate, systolic (SBP) and diastolic (DBP) BP, mean arterial pressure (MAP), pulse pressure (PP), and rate pressure products (RPP) were examined using automatic oscillatory method, while smoking status was determined with Youth Risk Behavior Survey (YRBS).
Results: After covariating for cofactors, the ANCOVA showed that CV hemodynamics were lower (p < 0.05), in the male adolescent smokers versus non-smokers. Additionally, regression showed that smoking predicted the reduction in SBP (20.6%), DBP (5.0%), MAP (13.4%), PP (7.5%), and RPP (13.4%).
Conclusion: The results suggest that cigarette smoking lowers CV hemodynamics in adolescent. However, more studies are needed to describe the mechanism(s) for lowering CV hemodynamics and explain the relationship of adolescent smoking with adulthood CVDs.
