LBW is one of the major determinants of neonatal survival and postnatal morbidity. Although LBW infants had lower anthropometric measure compared to national reference population, they had significance catch up growth compared to larger infants. The magnitude of catch up growth during infancy, especially the first 6 months of life is most critical in decreasing risk at adult shortness. The use of growth hormone can help in the development of those children born with IUGR or SGA. Socioeconomic, clinical, obstetric events and newborn diseases during hospital stay have repercussions on the infants progress. In the 6th month, weight catch up occurred in 52%, length catch up occurred in 52% and HC catch up occurred in 88% and complete catch up occurred in 52%. In our study HC catch up was the most predominant than weight and length, this may be due to HC growth is following the neural pattern of growth and is relatively independent on nutrition.
