ORELLANA, Jesem D. Y. et al. Prevalence of and factors associated with anemia in indigenous Surui women aged between 15 and 49 years in the Brazilian Amazon. Rev. Bras. Saude Mater. Infant. [online]. 2011, vol.11, n.2, pp.153-161. ISSN 1806-9304. http://dx.doi.org/10.1590/S1519-38292011000200006.
OBJECTIVES: to investigate the prevalence of and factors associated with the occurrence of anemia in indigenous Surui women aged between 15 and 49 years. METHODS: a cross-sectional study was carried out based on the 2005 census of Sete de Setembro indigenous territory in the Brazilian State of Rondônia. Hemoglobin measurement (Hb) was carried out using a portable β-hemoglobinometer. The cut-off points for anemia were Hb <12.0 g/dL in non-pregnant women and Hb <11.0 g/dL in pregnant women. Demographic and socio-economic data were gathered using a standardized questionnaire. The first stage of statistical analysis included the: chi-square; the chi-square linear tendency test; Student's t; a test for linearity and analysis of variance. In the second stage, the final logistic model was adjusted. RESULTS: the overall prevalence of anemia in non-pregnant women was 67.3% and, in pregnant women, 81.8%. Multivariate analysis showed that women with one or two anemic children aged between 6 and 35 months were three times more likely to be anemic; women from the lowest socio-economic stratum were 3.5 times more likely to be anemic. The likelihood of a Surui woman of low socio-economic status being anemic was 26% higher than that of one from the highest socio-economic stratum. CONCLUSIONS: anemia is a serious health problem among Surui women and is influenced by household factors, such as having children with anemia and socio-economic circumstances. It is suggested that measures to treat and prevent anemia among the Surui take these factors into account.
