Nível sócio-econômico como uma variável geradora de erro em estudos de etnia

Abstract: INTRODUÇÃOAlgumas variáveis biológicas caracterís-ticas do recém-nascido apresentam interesse em estudos de etnia. As diferenças raciais para estas variáveis podem indicar a existência de diferenças genéticas possíveis de serem avaliadas. Assim sendo, são conhecidas as relações existentes entre peso ao nascer e fatores ambientais e genéticos, tanto maternos quanto fetais 1,4,5,6 . Também são descritas diferenças raciais no peso ao nascer, sugerindo a ação dos fatores genéticos anteriormente citada 3 . Das vari… Show more

“…In Latin-American countries, where the population with black racial admixture usually belongs to the lower socioeconomic classes, this race-socioeconomic correlation may interact as compound variables, thus creating false positive correlations between race-dependent diagnoses and socioeconomic-dependent risk factors. Such a situation had already been identified within the material presented here for a false positive correlation between polydactyly and low birth weight, where the low birth weight was secondary to low socioeconomic level, which was associated with high Black racial admixture; polydactyly is known to be more frequent in Black than in any other ethnic group (Passos et al, 1978). Since PN have a higher frequency in Blacks, similar effects through socioeconomic differences are to be expected.…”
