The present hospital based study conducted on 602 mothers from middle (N=302) and low income group (300) examined
the maternal socio-economic and nutritional factors as antecedents of poor birth outcome. Women in the 9th month of
pregnancy were enrolled for the study excluding the cases of gestational diabetes, twins and preterm deliveries. Maternal obstetric
history and anthropometric measurements (weight and height) were recorded. Data on supplements and dietary intake data
were collected using 24 hour recall method and case papers. Weight, length, head circumference, chest circumference, abdomen
circumference, MUAC, triceps and supra iliac skin fold thickness of the neonates were measured within 48 hours of delivery
using standard methods. Poor maternal weight gain was observed with almost 71% women weighing less than 60 kg at term and
about 64% of the mothers had hemoglobin levels <11g/dl.
The incidence of low birth weight was higher in low income group (57%) than the middle income group (18%). The high
incidence of low birth weight (LBW) in the neonates resulted from low maternal age, weight, height and hemoglobin status
during the gestational period. The incidence of chronic severe malnutrition in the form of low head circumference for age Z-score
was highest in these neonates followed by wasting indicating higher growth restriction rate in late pregnancy. the NBW neonates
had significantly higher muscle and fat mass as compared to LBW neonates. The ratio of central fat to total fat was low indicating
absence of abdominal obesity and the ?thin fat phenotype? was not found in the present study.
