A total of 4,724 White and 1,013 Black healthy newborn children were investigated. No significant race differences were observed among those with apparently the same socioeconomic level. In two thirds of the comparisons made the values found in Porto Alegre proved to be higher than those encountered in other Brazilian populations. Multiple regression analysis performed in a subsample indicated an effect in the two racial groups of mother’s height and weight in the variable under investigation. Parity, age of father, and parents’ marital distance may also be important but in relation to them significant effects were observed among the Whites only.
