Background: Cardiovascular disease is resulted from malfunctioning’s of heart as well as blood vessels. More than two decades ago it was noted that the number of white blood cells can be an indicated of the existence of such disease. Platelet activation and aggregation are among the include processes. That are considered in pathophysiology of a coronary heart disease. However there seems to be a paucity of research on platelet count in patients suffering from obesity. Moreover although previous studies have indicated a positive correlation between platelet and white blood cells. Counts and mortality from coronary heath disease, how this might correlate with obesity is an issue still in need of more attention. Objectives: The present study was designed to evaluate platelet count and white blood cell count in those patients who suffer from obesity as compared with control subjects who were not obese. Methods: In this cross-sectional study, there were a total of 1024 Iranian subjects living in Hamedan include, staff of Islamic Azad University of Hamedan and subjects who referred to Ekbatan hospital in Hamedan during the period of 6 months randomly and staff of Islamic Azad University of Hamedan. The absence of infectious disease was confirmed by a general practitioner. Finally, the samples included 486 subjects, 254 male, and 232were females. Body mass index was calculated. Waist circumference in the Iranian subjects, at least in men 89 (cm) and women 91 (cm) was considered. White blood cell and platelet count was measured. T-test and Pearson’s correlation were run to analyze the collected data through SPSS software version 16. Results: The average age of the subjects was 34.75∓8.1 years. The body mass indexes in 7.6 percent of men and 15.7 of women were greater than 30 (kg/m2). The averages of waist circumference in men and women was 1.04∓0.5 and 89.3∓10.2 (cm), respectively. Also there seemed to be a significant correlation between waist circumstance and the number o
