Prevalence of anemia and associated factors were analyzed in mothers (n = 1,022) and their children under 5 years of age (n = 1,242) in Pernambuco State, Brazil, 2006. This was a cross-sectional population-based study with a probabilistic sample in an urban and rural area. Anemia was diagnosed by hemoglobin level (children < 11.0 g/dL, women < 12.0 g/dL) using HemoCue. Univariate and multivariate analyses used Poisson regression with robust adjustment of standard error, adopting a hierarchical model for determination in children with anemia as the outcome. This same procedure was not applied to mothers because of the small number of associated factors in the univariate analyses. Anemia prevalence was 16.4% in mothers and 34.4% in children. Anemic as compared to non-anemic mothers showed a prevalence ratio of 1.44 (95%CI: 1.21-1.72) for anemia in their children, maintaining similar values in the adjusted model (PR = 1.39: 95%CI: 1.16-1.66). Anemia prevalence in children was double that of mothers, with the final model showing only one common factor: per capita family income.
2006年，对巴西伯南布哥州1022名母亲及其1242名5岁以下儿童进行了贫血患病率及相关因素分析。这是一项基于人群的横断面研究，在城乡地区采用概率抽样。使用血红蛋白仪通过血红蛋白水平（儿童<11.0 g/dL，女性<12.0 g/dL）诊断贫血。单因素和多因素分析采用泊松回归并对标准误差进行稳健调整，采用分层模型以贫血儿童为结果进行判定。由于单因素分析中相关因素数量较少，此相同程序未应用于母亲。母亲贫血患病率为16.4%，儿童为34.4%。与非贫血母亲相比，贫血母亲的孩子贫血患病率比为1.44（95%CI：1.21 - 1.72），在调整模型中保持相似值（PR = 1.39：95%CI：1.16 - 1.66）。儿童贫血患病率是母亲的两倍，最终模型仅显示一个共同因素：家庭人均收入。
