AIM: the aim of the present study is to assess the levels of arterial stiffness   among obese subject and healthy subjects.

METHODS: A total of 80 participants were included with age groups between 18-30 yrs . participants are divided into two groups ,group I-obese (n=40) and group II non obese (n=40).Arterial stiffness was assessed by pulse wave velocity( Brachial ankle pulse wave velocity) and Augmentation index(ALX) .

RESULTS: Pulse wave velocity and Augmentation Index shows significantly positive correlation with BMI .

 CONCLUSION: increase in arterial stiffness was closely correlated to the body mass index, which indicating that adult obesity has a adverse impact on vascular adaptation.

KEYWORDS: pwv (pulse wave velocity), Augmentation index, body mass index(BMI).
