A total of 1325 normal, singleton babies (993 sinhalese and 332 moor) with ultrasonically confirmed period of gestation, born at the Maternity unit of the Base hospital Kegalle, were selected. Means and standard deviations for the above measurements of the sinhalese and moor babies were established. Since the number of babies were established. Since the number of babies belonging to the Tamil ethnic group was small for statistical analysis. they were excluded from the study. For all three measurements, the mean values of male newborns were higher than those of the female newborns. when compared with the sinhalese the moor, males and females had highly significant higher values for birth weight crown heel length and head circumfereence (P0.001) simple linear regression analyses were carried out between the baby's weight age and parity. A significant relationship was observed between the baby's weight and mothers weight.Health SciencesBirth weightPhysical developmentGestational ageEthnicitySocioeconomic statusAnatomyArticle
