The Relationship Between Vitamin D Level and Hepatosteatosis in Obese Children


The increasing incidence of obesity in children is a significant risk factor for nonalcoholic fatty liver disease and obesity-associated morbidity. In the present study, we aimed to explore the correlation between Vitamin D level and hepatosteatosis in obese children.


A total of 110 children aged 10-16 years who presented to pediatric endocrinology outpatient clinic for obesity were enrolled. The study was completed in a single season between September and November. Hepatosteatosis was diagnosed by ultrasonography. The patients were grouped into two groups: Group 1 comprised patients with hepatosteatosis and Group 2 consisted of patients without hepatosteatosis. 25 hydroxy (25-OH) Vitamin D levels were compared between patients with and without hepatosteatosis.


No statistically significant difference was observed between 25-OH Vitamin D levels of patients with and without hepatosteatosis. When the effects of age and sex were kept constant, there was no significant correlation between Vitamin D level and aspartate aminotransferase, alanine aminotransferase, and body mass index values.


Unlike the results of the previous studies, we were unable to detect any significant difference between Vitamin D levels of obese patients with and without hepatosteatosis. We think that obesity, rather than Vitamin D status, that is, in fact, independently associated with nonalcoholic fatty liver disease. Larger studies are needed to investigate the impact of Vitamin D in children with obesity with hepatosteatosis.
