The ratio correlates significantly with weight gain during pregnancy and the socio-economic ststus of the mother. The ration is a more adequate indicator of a neonate at risk than birth weight alone. It is suggested that a birth weight of less than 5.5perc. of the weight of the mother during the first trimester be used by a birth-attendant as an indicator for referral to a more qualified person, when the mother is of low body weight and of poor nutritional statusMedical SciencesPregnancyNutritional statusSocioeconomic statusNeonatal developmentMaternal fetal exchangeArticle
