The role of iron and vitamin A in adolescent growth and development is not well described. During adolescence iron requirements are increased, reaching a maximum at peak growth, but after menarche, menstrual iron loss must also be replaced. An observed rise in retinol-binding protein concentrations at puberty level 4 indicates a role for vitamin A in sexual maturation. Iron and vitamin A deficiencies may slow the tempo of growth. Conversely, for girls on marginal diets, an extended catch-up growth period may lead to depletion of these nutrients. The costs of achieving growth may also include cephalopelvic disproportion in girls becoming pregnant and increased risk of menorrhagia.
