RESUMO
The relationship between social class and nutritional status, although frequently presumed true, has scarcely ever been studied empirically. The health and nutritional status of a sample of children from different social classes in the city of S. Paulo (Brazil) are studied by means of an on operational classification of social class. Through the analysis of the height for age distribution normal growth--and, therefore, favourable health status--as found only among the burgeoisie and the small-burgeoisie, these two classes together constituting about 30% of the total population. Significant divergences from an expected anthropometric standard were found among all the segments of the working-class population. Differences in income and schooling among the classes corroborate the empirical link found between social class and health and nutritional status.
