Background: The aim of this study was searching for the orientation and degree of association, and receiver operating characteristic (ROC) curves between waist circumference (WC) and high-density lipoprotein cholesterol (HDL-C) of Korean adults for the new recommended WC values.
Methods: This study analyzed 5,069 Korean adults of the 2015 Korea National Health & Nutrition Examination Survey, using Pearson’s correlation analysis, partial correlation analysis between WC and HDL-C with other significant variables to HDL-C controlled, and ROC curves.
Results: WC had the highest Pearson’s correlation coefficient to HDL-C at -0.289 (P&0.01) in men, and -0.318 (P<0.01) in women. With other significant variables controlled, the partial correlation coefficient between WC and HDL-C became -0.250 (P<0.001) in men and -0.191 (P<0.001) in women. WC had the biggest area under the curve (AUC). For HDL-C≤40 mg/dL, the AUC values of WC were 0.633 (99% confidence interval [CI]: 0.600?0.666; P<0.001) in men and 0.684 (99% CI: 0.648?0.719; P<0.001) in women. For HDL-C≤60 mg/dL, the AUC values of WC were 0.654 (99% CI: 0.612?0.696; P<0.001) in men and 0.661 (99% CI: 0.632?0.690; P<0.001) in women.
Conclusion: There was an inverse correlation between WC and HDL-C in Korean adults. While WC showed the strongest relation with HDL-C in both sexes, the scale of their interrelationship in men was larger if other significant variables were controlled. The new recommended WC values obtained by ROC curves of this study were ≤87.5 cm (better if ≤84.5 cm) in men, and ≤81.5 cm (better if ≤78.5 cm) in women.
