Abstract
Abstract Disclosure: H. Chung: None. Background: Sarcopenic obesity is related with a higher risk of cardiovascular disease, metabolic disease, and mortality than obesity alone. Nevertheless, few studies have investigated body shape indices for the assessment of sarcopenia in obese populations. The purpose of this study was to evaluate the accuracy of the Z-score of the log-transformed A Body Shape Index (LBSIZ) to assess sarcopenia in nationally representative populations with central obesity. Methods: Data from Korea NHANES (KNHANES) and the U.S. National Health and Nutrition Examination Survey (U.S. NHANES) were evaluated. Sarcopenia for the Korean population it was defined when appendicular skeletal mass index (ASMI ) < 7 kg/m2 in men or ASMI < 5.4 kg/m2 in women, according to the Asian Working Group for Sarcopenia and for the American population was defined when ASMI < 7 kg/m2 in men or ASMI < 5.5 kg/m2 in women, according to the revised European consensus on definition and diagnosis for sarcopenia. LBSIZ cut-off value was defined as that with the highest score of the Youden’s index. Changes in odds ratios (OR) for sarcopenia were investigated using restricted cubic spline (RCS) plots. Results: This study was conducted for population with central obesity in 4,855 Koreans and 8,010 Americans. Among these, 330 Koreans and 373 Americans were accompanied with sarcopenia. The cut-off values for the LBSIZ were 1.15 (sensitivity, 78%; specificity, 77%) for Korean men, 0.95 (sensitivity, 74%; specificity, 69%) for Korean women, 1.05 (sensitivity, 88%; specificity, 82%) for American men, and 0.45 (sensitivity, 77%; specificity, 71%) for American women in the development groups. Comparable results were verified in validation groups. The RCS plot indicated that ORs for sarcopenia rapidly increased with an increase in the LBSIZ cut-off value. Conclusion: The LBSIZ index is a powerful and reliable indicator of sarcopenia in adults with central obesity. Presentation: Friday, June 16, 2023
