Abstract
Background: We already know the relationships between non-alcoholic fatty liver disease (NAFLD) and dyslipidemia, but most studies have focused on extremely obese people. At this time, weight loss is the only definite therapy for fatty liver disease. Because the concept of a “obesity paradox” has been gaining prominence, we have attempted to show the relationships between indexes of dyslipidemia and fatty liver disease on abdominal sonography for people with body mass indexs (BMIs) less than 30 kg/m2 and with lowest death rate.
Methods: The subjects were 4,768 patients who underwent BMI evaluations, blood tests, abdomen ultrasonography, and public corporation medical exams at a hospital health clinic in Suwon, Gyeonggi-do between January 2013 and December 2014, and were retrospectively enrolled in the study. They were over 20 years old, and we excluded patients who had viral hepatitis A, B, or C, suspected liver cirrhosis on abdominal sonography, or BMIs >30 kg/m2.
Results: The correlation coefficient of dyslipidemia indexes and NAFLD was calculated, triglyceride 0.359, total cholesterol 0.208, low density lipoprotein cholesterol 0.161. Triglyceride in particular had the strongest correlation.
Conclusion: Because triglyceride had the strongest correlation with NAFLD in non-obese people, we suggest that it may be predictive of increasing obesity and NAFLD among people with BMIs less than 30 kg/m2.
