Abstract
Background: Obesity is characterized by the presence of excess body fat (BF). Individuals with excess BF are vulnerable to cardiovascular disease (CVD). The study objective was to determine the relationship between BF percentage and the prevalence of CVD risk factors and to determine optimal BF cutoffs predictive of obesity-related CVD risk factors.

Methods: Data were derived from the Korea National Health and Nutrition Examination Survey of the Korean population, conducted in 2009?2010. We surveyed 4,988 men and 6,553 women aged 20 years or older. We investigated the BF percentage (measured by dual-energy X-ray absorptiometry) and prevalence of CVD risk factors (hypertension, diabetes mellitus, and dyslipidemia).

Results: There were strong and graded associations between increasing BF percentage and the prevalence of CVD risk factors. The first cut-off values (defined as being overweight) in men and women were 22.6% and 33.9%, respectively, and the second cut-off values (defined as obesity) were 26.2% and 37.3%.

Conclusion: We concluded that men have a lower percentage BF than women and that susceptibility to CVD and its risk factors is greater in Korean men than in Korean women. These results indicate the need for life-long monitoring and management of obesity.
