Birth weight of neonates as an indicator of morbidity and mortality in adult age and factors which influence it

In 28 neonates born by spontaneous delivery to healthy mothers with a normal course of gestation venous umbilical blood was examined to assess the immunoreactive insulin concentration. Moreover, the birth weight of the neonates was recorded, the weight increment of the mother during pregnancy and the body mass index at the end of gestation. By means of a questionnaire and the computer programme Progana the dietary intake of the mothers at the end of pregnancy was assessed and compared with recommended allowances. The assembled data were evaluated statistically by assessment of the correlation coefficient. The investigation revealed that the birth weight of the neonates in the group does not correlate with the immunoreactive insulin concentration in umbilical venous blood. Although the dietary intake of the mothers at the end of pregnancy is not ideal (fat and cholesterol intake predominates over carbohydrate and protein intake), it does not correlate with the birth weight of the neonates nor with the immunoreactive insulin concentration in umbilical venous blood. From these results the conclusion is drawn that neonates with a low birth weight do not have a higher plasma insulin concentration after delivery and that the mother's diet at the end of pregnancy does not influence the birth weight and insulin level in neonates.
