Associations of visceral and hepatic fat with serum 25-hydroxyvitamin D concentrations

Introduction: Obesity is associated with lower serum 25-hydroxyvitamin D (25(OH)D) concentrations. A major explanatory hypothesis is that vitamin D is sequestered by adipose tissue. Another hypothesis is a decreased hepatic activation by 25-hydroxylase in obese individuals. Because adipose tissue has different characteristics and functions in different parts of the body an important question is whether serum 25(OH)D is more strongly related to visceral (VAT), hepatic, or total...

Introduction: Overall and abdominal obesity are both well-established risk factors of vitamin D deficiency. However, it is unclear which fat depot is most strongly related to serum 25-hydroxyvitamin D (25(OH)D) concentrations.Objective: This study aims to distinguish specific contributions of total body fat, abdominal subcutaneous adipose tissue (aSAT), visceral adipose tissue (VAT) and hepatic fat on 25(OH)D concentrations.Methods...
