This population-based study was designed to detect the prevalence of anemia in a healthy population of children (18 months to 7 years) and women (14 to 30 years) tested in 2006-2007 in the state of Rio Grande do Sul, Brazil as part of an effort to tackle this massive problem that still affects so many people in the XXI century. Anemia was defined according to the WHO. Capillary blood was measured and socioeconomic status was determined according to the Brazilian Association of Market Research Agencies. The median prevalence of anemia in 2198 children was 45.4% and in 1999 women 36.4%. Anemia decreased with age during childhood; although significantly more prevalent in lower classes individuals, it was also high in the upper classes. There are indirect evidences that the lack of iron supplementation and/or iron fortified food may play a role in it. Professionals and society wise measures of education have to be implemented in order to address possible biologic factors involved in childhood psychosocial development in southern Brazil.
本基于人群的研究旨在检测巴西南里奥格兰德州 2006-2007 年接受检查的健康儿童（18 个月至 7 岁）和妇女（14 至 30 岁）中贫血的患病率，该研究是解决这一在 21 世纪仍影响众多人的重大问题的努力的一部分。贫血根据世卫组织的定义进行定义。毛细血管血样被测量，社会经济地位根据巴西市场研究机构协会确定。2198 名儿童中贫血的中位数患病率为 45.4%，1999 名妇女中贫血的中位数患病率为 36.4%。儿童期贫血随年龄而下降；尽管在较低阶层个体中更为普遍，但在较高阶层中也很高。有间接证据表明，缺乏铁补充剂和/或铁强化食品可能在其中发挥作用。专业人员和社会明智的教育措施必须实施，以解决巴西南部儿童社会心理发展中可能涉及的生物学因素。
