Background: Obesity is associated with metabolic syndrome and cardiovascular risk factors. We examined metabolic
syndrome and cardiovascular risk factors by percent body fat difference in adult with normal weight adults.
Methods: We analysed 353 subjects whose body mass index (BMI) were between 18.5 and 23 kg/m2. They
were examined in a health promotion center of a general hospital from Jan. to Dec. 2009. Age, gender, height,
weight, BMI, waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting
blood sugar (FBS), hemoglobin A1C, lipid profiles, fat free mass, lean body mass, body fat mass, percent body
fat (%BF) were checked. Subjects were divided into two groups according to their %BF by 25% in men, 30% in
women and analysed about metabolic syndrome and cardiovascular risk factors.
Results: The average age was 47.30±10.83 years old, and BMI was 21.75±1.32 kg/m2, %BF was 22.92±5.53%
in men, 26.67±6.32% in women. High %BF group showed increased BMI, WC, SBP, DBP, serum FBS, total
cholesterol, triglyceride, low-density lipoprotein cholesterol and body fat mass decreased high-density lipoprotein
cholesterol, fat free mass and lean body mass. High %BF group showed increased frequency of metabolic
syndrome components, hypertension, and dyslipidemia. Diabetes was increased in high %BF group of
women. The result of binary logistic regression analysis with age adjusted, metabolic syndrome, hypertension
and hyperlipidemia was related with %BF in men, metabolic syndrome, diabetes, hypertension, hyperlipidemia
was related with %BF in women.
Conclusions: High %BF was associated with metabolic syndrome and cardiovascular risk factors like hypertension,
dyslipidemia in both men and women with normal weight. But, high %BF was associated with diabetes
in only women in this study.
