To elucidate the long-term consequences of osteopenia of prematurity, lumbar spinal bone mass was measured in 21 preterm-born children aged 3-4 years by dual-energy X-ray absorptiometry. Their mineral intake remained low during early life, and all 11 infants previously studied were osteopenic at term postconception. At the age of 3-4 years, however, all 21 children were found to have normal bone mineral content and density with slightly elevated serum osteocalcin levels. Our results show that in preterm-born children spontaneous resolution of lumbar spinal osteopenia occurs during early childhood.
