This critique examines not only the pathophysiological and molecular mechanisms of newborn osteopenia but also the risk factors and investigation. Osteopenia of premature infants has improved incidence amongst other ailments of prematurity. Identification of danger factors is essential for monitoring of osteopenia. A few of the risk elements contain low birth weight, prematurity, long-term administration of drugs such as corticosteroids, methyloxanthines, furosemide, abnormalities in vitamin D metabolism, poor maternal GLUT4 manufacturer nutritional and mineral uptake etc. Neonatologists, pediatricians and endocrinologists should investigate premature, low birth weight infants which have high serum alkaline phosphatase and have at the least a single risk issue.Important WORDS: premature infants; osteopenia; bone metabolism; low birth weight; vitamin D metabolism.birth weight (VLBW), osteopenia is usually a common result in of pathological fractures. Decreased BMD can be a result of either decreased bone mineralization or increased bone reabso.
