The continuous advances in intensive care have led to increased survival of premature infants. As a consequence, the problem of less imminent, slowly progressing disorders such as osteopenia of prematurity has been emerging. Osteopenia of prematurity (OOP) also called metabolic bone disease of prematurity (MBD) or rickets of prematurity is characterized by a reduction in bone mineral content usually manifest between 6th to 12th weeks of corrected gestational age. It occurs in up to 55% of infants born with weight <1000gm and 23% of infants weighing <1500gm. Clinical features of osteopenia of prematurity are mostly non-specific often appears as a late symptoms. Several biochemical markers have frequently been used as screening tools and diagnostic markers, but timing of measurements and the levels at which treatment should be initiated vary widely. Dual energy X-ray absorptiometry (DEXA) and Quantitative ultrasnogram are important diagnostic tool. Standard X-ray, a widely accepted but cannot detect osteopenia unless 20% loss of bone mineralization. The treatment of osteopenia includes provision of adequate mineral supplementation. Monitoring of serum and urinary markers are mandatory. The focus on prevention has largely centered on providing adequate intake of phosphorus and calcium but more research is needed. Till date there are neither enough data regarding clinical risk factors, valid biochemical markers which can detect premature babies at risk of osteopenia nor supplementation as well as appropriate timely management protocol is practicing in Bangladesh.
