Human umbilical endothelial cells (HUVECs) have a sex: characterisation of the phenotype of male and female cells
BACKGROUND The birth weight is influenced by intrauterine environmental factors and genetic factors. The main determinants of birth weight are gestational age and sex. The purpose of this study was to investigate the correlation between mothers birth weight with the first child birth weight. METHODS We prospectively measured weight, height and cephalic perimeter of normal newborns of both sexes. At the same time sought the birth weight of the mother. The data were analyzed in a Pearson correlation matrix. RESULTS We studied 180 mothers and infants, 99 boys and 81 girls. The correlation coefficient between maternal birth weight and child birth weight was for males 0.321 (p 0.001) and for females was 0.216 (p 0.053). CONCLUSIONS In the present sample, maternal birth weight was significantly correlated only with firstborn male's birth weight.
