About The Study: In this cross-sectional study of preadolescent children, greater lean mass and higher fitness were associated with fewer anxiety and depression symptoms, while higher visceral adipose tissue was associated with increased symptoms of both. Body fat percentage was only associated with greater anxiety. These findings highlight the roles of body composition in mental health and underscore the value of early identification of physical health markers to support children’s well-being and development.
