La magrezza è una condizione che interessa una quantità non trascurabile della popolazione in età infantile e adolescenziale. La maggior parte dei soggetti magri presentano una magrezza idiopatica o costituzionale, che rimane una diagnosi di esclusione rispetto a diverse forme patologiche. Ulteriori studi sono necessari per confermare l’aumentato rischio di morbilità e mortalità in questi soggetti e per definire le correlazioni esistenti tra magrezza, sviluppo puberale e raggiungimento della statura finale.
