OBJECTIVES:The purpose of the study was to determine whether there exists a positive correlation between the mother's parity and the child's weight on delivery. MATERIALS AND METHODS:A retrospective study has been conducted on a selected group of 86 multiriparas with three deliveries. Only in term babies of healthy mothers were taken into consideration. Data derived from cases has been analyzed by means of Microsoft Excel and Statistica 6.0 software. RESULTS:In 65.1% of the cases, the birth weight of the second neonate exceeded the weight of the first one. The rate diminishes to 51.2% when we compare the third child with the second. In 2.3% of the records no changes have been observed. The abovementioned criteria enabled us to form three groups out of the initial cohort and perform further analysis. CONCLUSIONS:Significant correlation between birth weight of the first and second newborn has been found. No such correlation was found in the case of the second compared to the third delivery.
