Socio-biological determinants of birth weight

A study on a few selected socio-biological determinants of birth weight was conducted at a rural project hospital in Haryana. Records of 2292 singleton live births over a period of two years (1985-1987) were analysed, by bivariate and multivariate methods. The mean birth weight of the infants was 2715 g (S.D. 453). Mean birth weight of male infants was 92 g more than female infants. Literacy levels of both parents, maternal age, parity, place of residence and antenatal care were found to have significant influence on the birthweight. Multiple regression showed that maternal age, maternal literacy and place of residence had minimal influence on the birth weight compared to other factors.
