Toemen L, Santos S, Roest AA, et al. - Researchers conducted this population‐based cohort study to explore the correlations of body fat distribution and overweight with cardiac measures obtained by cardiac magnetic resonance imaging in school‐age children. Two thousand eight hundred thirty-six children, 10 years of age, participated in the study. Anthropometric measures, dual‐energy X‐ray absorptiometry, and magnetic resonance imaging were used to collect data on body mass index, lean mass index, fat mass index, and abdominal visceral adipose tissue index. According to findings, a higher body mass index in childhood is correlated with a larger right and left ventricular size. The higher lean mass influences this association. In childhood, lean mass can be a more effective determinant of heart growth than fat mass. At older ages, fat mass can affect the cardiac structures.
