Sociobiologic factors influencing low birth weight at a rural project hospital.

ABSTRACT

The incidence of low birth weight (less than or equal to 2500 g) was 38.9% among 2292 singleton live births at a rural project hospital in Haryana. Only 7.0% of the newborns weighed 2000 g or less. Female babies had a higher incidence of low birth weight. Other factors considered were maternal age, parity and literacy and father's literacy. Young mothers (less than 20 years) had a higher incidence of low birth weight. Similarly parents who were illiterate or educated to below the primary grade also had a higher incidence of low birth weight. The maximum percentage of low birth weight was seen in the primiparous mothers. An increase of low birth weight was also seen after the 4th parity. The best outcome was at para 4.
