The primary purpose of the study was to compare cardiovascular function, mental health indices, stress-related variables according to body mass index (BMI) and percent body fat (%BF) in 20s females. Sixty-eight women, aged 20-29 yrs, participated in the study as subjects. There were three groups, i.e., normal group (BMI<24 kg·m-2 and %BF<25%; n=25), normal weight obese group (BMI<24 kg·m-2 and 28%<%BF<40%; n=19), and obese group (BMI>26 kg·m-2 and 28%<%BF<40%; n=24). Cardiovascular function, mental health indices, stress-related blood variables were measured and compared among three groups. Main results of the present study were as follows: 1) SBP, DBP, mean arterial pressure, and RPP were significantly higher in obese group than normal group. 2) There were no significant differences in mental health indices among three groups. 3) Fasting plasma insulin, fasting plasma glucose, and CRP were significantly higher in obese group than normal weight obese group and normal group. It was concluded that there would be abnormal cardiovascular function, insulin resistance, and inflammation in general obese individuals in 20s females, not normal weight obese and normal individuals.
