Conception and motherhood are the most beautiful and unique experiences for women in a lifetime. Normally growth and development of fertilised ovum in utero continues to maturity till 40 weeks. This growth is controlled by a multiplicity of factors. In both underdeveloped and developing countries, the problem of LBW’s is alarming and it is an important factor affecting neonatal mortality and childhood morbidity.
Aims and Objective: The Aim of the study is to find out some maternal factors affecting the neonatal birth weight
Material & method: Study was done in obstetrics wing of LLRM Medical College and SVBP hospital, Meerut. The antenatal mothers having 2 nd half of pregnancy who knew their LMP are the case study cases. But those suffering from chronic diseases hampering the physiological process such as maternal malnutrition, infections, hypertensive disorders, and toxaemia of pregnancy, haemolytic diseases, multiple pregnancy and diabetes were excluded from the study. Neonates with congenital malformation and haemolytic diseases were also excluded. Only 100 singleton pregnancy delivering in the hospital were taken. The results are tested statistically Chi-square test, to test the difference of two proportions. In our study the critical age of mother is 17-20 years and ≥ 36 years for LBW (33.33%).The incidence of LBW is 30%. Most of LBW’s weight between 2100-2400 gms. Multiparity (parity≥4) delivered maximum number of LBW. Critical level of hemoglobin is ≤ 7.5 gm/dl for delivery of 62.5% of LBW. Significant link is found between maternal hemoglobin and neonatal birth weight.
