Prevalences of malnutrition and overweight among children under five years and its association with socioeconomic, demographic and health indicators were estimated for the six largest municipalities of Maranhão, in 2006/2007. By means of a household survey, a sample of 1214 children under five years of age was randomly selected. Two-stage cluster sampling was used, representing the six municipalities of Maranhão with over one hundred thousand inhabitants. Standardized questionnaire was administered to mothers or guardians and trained personnel measured weight and height or length. For classification of malnutrition cutoff points of <-2z scores for weight-for-age, weight-for-length/height and length/height-for-age were used. Overweight was considered when weight for height was > +2 z score, following World Health Organization guidelines. By weight-for-age malnutrition prevalence was 4.5, by length/height-for-age 8.5% were stunted and by the weight-for-length/height 3.9% were malnourished (wasting), while 6.7% were overweight. Children of families headed by women had lower prevalence of malnutrition (prevalence ratio=0.4). Socioeconomic variables were not associated with malnutrition or overweight. Participation in money transfer programs from the government was not associated with malnutrition or overweight. The prevalence of malnutrition was low, but being overweight was more prevalent than malnutrition. Social inequality was not detected in relation to malnutrition in children under five years of age, suggesting a favorable trend towards greater equity.

Resumo O objetivo do presente estudo foi avaliar desigualdade racial na atenção ao parto e ao nascimento na Rede Cegonha utilizando indicadores de boas práticas e intervenções obstétricas. Desigualdade racial, mensurada pelo efeito total da raça/cor no modelo sem ajuste, foi detectada em muitos indicadores. A persistência do efeito direto, após ajuste para os mediadores idade, escolaridade, paridade, hospital de alto risco e região geográfica, sugere discriminação racial contra as pretas, que tiveram menos partograma preenchido (RP 0,88; IC 95% 0,80-0,95). Comparadas às brancas, as pretas ficaram menos em litotomia (RP 0,93; IC95% 0,89-0,98), realizaram menos episiotomia (RP 0,81; IC95% 0,68-0,96) e tiveram menos dor na sutura da episiotomia (RP 0,66; IC95% 0,51-0,87), sugerindo que boas práticas estariam sendo mais realizadas nas pretas. Entretanto, pelo modelo intervencionista de assistência, ainda adotado por muitos profissionais, essas práticas são de rotina e a menor realização delas nas pretas seria melhor interpretada como evidência de discriminação racial a essas mulheres. Para outros desfechos, o efeito da raça/cor desapareceu após o ajuste para mediadores, sugerindo atenuação ou desaparecimento do efeito da cor da pele em algumas práticas/intervenções na assistência ao parto e nascimento.
