We examined whether overall obesity (body mass index, BMI) and abdominal obesity (waist circumference, WC) are independently associated with the risk of hypertriglyceridemia (HG) among the Korean population. A national sample of 5,036 Koreans aged 19–64 was examined with cross‐sectional surveys, the Korea National Health and Nutrition Examination Survey (KNHANES), in 2007 and 2008. BMI, WC, and other life‐style information were assessed. We documented 1,344 cases (26.7%) of HG (fasting triglycerides of >150mg/dl). Both BMI and WC were each independently associated with the risk of HG. Multivariate ORs of increasing categories of BMI (<18.5, 18.5≤ – <23, 23≤ – < 25, 25≤ – <28, ≥28 kg/m 2 ), were 0.49, 1.00 (reference), 1.26, 1.63, and 1.84, respectively ( p= 0.0007) adjusting for WC. WC was also positively associated with risk of HG across increasing quintiles of WC (multivariate‐adjusted ORs: 1.00 (reference), 1.54, 2.54, 2.21, and 2.36; p <0.0001), adjusting for BMI. The joint relation between BMI and WC and risk of HG showed that within each BMI category, higher WC predicted a greater risk of HG ( p <0.0001). The ROC curves indicated that BMI (0.69) and WC (0.72) were similar in predicting HG. In conclusion, both BMI and WC were strongly independently associated with risk of HG among this Korean population. Both measurements should be used for assessing health risk in clinical settings and epidemiologic research among Asian population.
