Core Tip
Core tip: Recent studies in children demonstrated that the prevalence of prediabetes increases with increasing hepatic fat content, and that fatty liver plays a central role in the impairment of liver, muscle and adipose insulin sensitivity. Pancreatic fat was identified as a novel obesity-related fat depot, which might contribute to the development of β-cell dysfunction. This study demonstrated that in overweight/obese children with nonalcoholic fatty liver disease (NAFLD), pancreatic fat is increased compared with those without NAFLD. However, only liver fat is independently related to prediabetes. Early intervention during childhood to recognize NAFLD might be critical in averting an unfavorable metabolic phenotype.
