Background: Obesity is a predisposing risk factor for cardiovascular disease (CVD). Body mass index (BMI) is a commonly used indicator to assess obesity. The objective was to evaluate the relationship between body fat (BF) percentage and three obesity indicators: BMI, waist circumference (WC), and waist circumference to height ratio (WHtR). We also analyzed the waist-to-height ratio as a screening tool for CVD risk factors.
Methods: The Korea National Health and Nutrition Examination Survey in the Korean population was conducted from 2009 to 2011. We surveyed 8,013 men and 10,161 women aged 19 years or older. We investigated the BF percentage, BMI, WC, and WHtR. We analyzed the relationship between the WHtR and the prevalence of CVD risk factors. We analyzed odds ratios of CVD risk factors according to the WHtR groups.
Results: There was a statistically positive correlation between BF percentage and the obesity indices. There were strong associations of increasing WHtR with the prevalence of CVD risk factors. The three obesity indicators were statistically significant in predicting CVD risk factors. There was a strong correlation between increased WHtR and increased prevalence of CVD risk factors.
Conclusion: The cutoff value for WHtR related to CVD risk factors was 0.48 for men and 0.49 for women. The WHtR should therefore be considered as a screening tool.
