Избыточная масса тела и ожирение, определенные методом биоимпедансометрии, но не по ИМТ, ассоциированы с более высоким уровнем сывороточного ферритина. Дефицит железа ассоциирован с более низкими темпами полового развития у мальчиков.</p></abstract><trans-abstract xml:lang="en"><p>   The aim of the study was to analyze the possible impact of iron deficiency without anemia on physical and sexual development of adolescent boys.</p><p>   Physical development of adolescent boys with iron deficiency without anemia did not differ from that of their healthy peers. Iron deficiency without anemia did not altered physical development of adolescent boys. Obesity or excess weight is associated with a higher serum ferritin level, which should be considered when diagnosing iron deficiency.
