Associations Between Body Composition and Metabolic Health in Children With Obesity
Maternal &Child Nutrition, EarlyView.ABSTRACT Childhood obesity is an increasing public health problem with heterogeneous metabolic health outcomes. In children, distinguishing differences in body composition between individuals with metabolically healthy obesity (MHO) and those with metabolic syndrome (MS) may be useful for understanding the impact of body composition on metabolic health.
