Waist circumference is a significant predictor of adverse outcomes, and this study investigated the correlation between abdominal obesity patterns and non-alcoholic fatty liver disease (NAFLD). Data from 4467 adults without NAFLD were analyzed, and participants were classified into four groups based on their two-year waist circumference patterns. The results showed that persistent and progressed abdominal obesity were associated with a higher risk of NAFLD in both genders, while maintaining a lean waist circumference was more effective in preventing NAFLD in men.
Waist circumference (WC) is an important predictor of long-term adverse outcomes. We aimed at assessing the correlation between abdominal obesity (AO) patterns and non-alcoholic fatty liver disease (NAFLD). Data from 4467 adults aged 40-69 years and without NAFLD who participated in the Korean Genome and Epidemiology Study were analyzed. Participants were classified according to two-year WC pattern into four groups: persistent lean WC, improved AO, progressed to AO, and persistent AO. NAFLD was defined as NAFLD-liver fat score >-0.640. Multiple Cox proportional hazards regression analysis revealed that the fully adjusted hazard ratio (HR) (95% confidence intervals (CIs)) for NAFLD in persistent AO, progressed to AO, and improved AO groups compared to the persistent lean WC group was 1.33 (1.13-1.57), 1.73 (1.48-2.02), and 1.06 (0.84-1.33), respectively. Women in persistent AO or progressed to AO groups had significantly higher risk for NAFLD than those in persistent lean WC or improved AO groups. Men who had progressed to an AO event over two years had significantly higher risk for NAFLD than those without any AO event over two years. Maintaining lean WC and improving AO would be successful strategies for preventing NAFLD in women, while maintaining lean WC would be more effective in men.
