    Abstract:
    BACKGROUND: Obesity is an important risk factor for non-alcoholic fatty liver disease. Few studies have evaluated the association between vitamin D and non-alcoholic fatty liver disease in obese children. Therefore, we conducted a study to examine the relationship of vitamin D levels and hepatosteatosis in obese children. METHODS: One hundred and eleven children with obesity participated in this study. Hepatosteatosis was diagnosed and graded using ultrasonography in all patients. Study participants were divided based on the presence of hepatosteatosis into two subgroups (hepatosteatosis and non-hepatosteatosis). Serum levels of 25-hydroxyvitamin D, calcium, phosphate, alkaline phosphatase, parathormone, and lipids were measured and compared. RESULTS: Hepatosteatosis existed in 52% of obese children without chronic diseases. There was no statistically significant difference in the vitamin D level between the hepatosteatosis and non-hepatosteatosis groups. Alanine aminotransferase levels and the triglycerides-to-high density lipoprotein ratio were significantly higher, and the high density lipoprotein levels were significantly lower in the hepatosteatosis group compared to the non-hepatosteatosis group. CONCLUSIONS: Vitamin D deficiency is not directly related with hepatosteatosis. A high ALT level and a high triglycerides-to-HDL ratio and low HDL levels are more significant in hepatic steatosis in obese children.
