Association Between Maternal Age with Maternal hematological indices and Anthropometric status in Neonatal: A Case-Control Study

This study was conducted to determine the relationship between maternal age during pregnancy and maternal hematological parameters and anthropometric status in neonatal.

In this study, 32 mothers aged 35 years and older (case group) and 292 mothers aged 20-35 years (control group) were examined. Maternal age and hematologic parameters were evaluated before delivery. The weight, height and head circumference were measured in infants. The relationship between prenatal age of mothers and infant’s anthropometric indices were calculated using the Pearson correlation coefficient.

The comparison between the two groups showed no significant difference in the type of delivery, history of abortion, systolic and diastolic blood pressure and hematological parameters. In addition, there was no significant difference between the two groups in the sex, weight, head circumference and height of the infants. A significant negative correlation was observed between prenatal age of mothers with the number of monocyte (Mid) cells (P <0.05), number of red blood cells (P<0.05), number of white blood cells, and granulocytes (P<0.001) in mothers. Also, a significant correlation was observed between the prenatal age of mothers with number of low birth weight (LBW) (Positively, P<0.01), weight (Negatively, P<0.01), head circumference (Negatively, P<0.001) of infants.

The results of this study showed that the number of infants with LBW increases with increasing mother's age. Also, maternal age can significantly associate with some maternal hematological parameters and the anthropometric indices of infant.
