Abstract

Abstract : Background: Body mass index and waist circumference (WC) are commonly used metrics that reflect general obesity and abdominal obesity. However, the impact of general and abdominal obesity discrepancies on the risk for major adverse cardiac events (MACE) is less explored. Methods and Results: The study population was derived from the Korean National Health Insurance Service‐Health Screening Cohort. Among 315 982 participants aged 40 years or older who underwent health examinations between 2008 and 2009, body mass index and WC were used to determine the obesity status. The participants were followed from January 1, 2010 for MACE until December 31, 2015. Cox proportional hazards models were used to evaluate the association of obesity and the risk of MACE. Compared with men who were not obese, those with abdominal obesity without general obesity (adjusted hazard ratio (aHR) 1.29, 95% CI 1.16–1.43), and general and abdominal obesity (aHR 1.20, 95% CI 1.12–1.29) had elevated risk of MACE, while those with general obesity without abdominal obesity (aHR 1.06, 95% CI 0.98–1.16) did not. Similarly, women with abdominal obesity without general obesity (aHR 1.13, 95% CI 1.03–1.24) and those with general and abdominal obesity (aHR 1.15, 95% CI 1.06–1.25) had increased risk of MACE, while those with general obesity without abdominal obesity (aHR 1.07, 95% CI 0.88–1.30) did not. Conclusions: Abdominal obesity without general obesity was associated with an elevated risk of major cardiovascular outcomes while general obesity without abdominal obesity did not. Concurrent determination of body mass index and WC may be beneficial for the accurate determination of future cardiovascular risk.
