To estimate the magnitude of the anemia, to analyze the time trends and investigate the factors associated with this disturbance in children in the state of Paraíba, Brazil.
A cross-sectional survey, of population-based, with 1108 children, aged 6 to 59 months, both sexes in the state of Paraíba. Hemoglobin (Hb) in venous blood was analyzed with an automatic counter. The social-economic and demographic characteristics of children were obtained by questionnaire. Proportions were compared by Pearson's chi-squared test, and the association between hemoglobin concentrations and potential risk factors was tested by regression model Poisson. The time trend of anemia was assessed by the increase/decreased in the prevalence of anemia, using as comparison the prevalence observed in the years 1982, 1992 and 2007.
The prevalence of anemia (Hb < 11.0 g/dl) in the state of Paraíba was 36.5% (CI95% 33.7 to 39.3). It was observed that 1.3% (CI95% 0.7 to 1.8) were in severe form (Hb <7.0 g/dl), 11% (CI95% 9.4 to 13.5) in a moderate form and 87.6% (CI95% 79.1 to 91.2) in the mild form. There was an increase 88.5% in cases of anemia between the years 1982-1992 and stabilization in the prevalence between the years 1992-2007. The analysis adjusted Poisson model showed a greater susceptibility to anemia in children 6 to 24 months of age, those breastfed for six months or more, who co-inhabited with more than 04 people in the same household and lived in houses with less than 05 rooms.
The results revealed that anemia remains an important public health problem in the state of Paraíba and despite having been shown an stabilization in the prevalence of anemia between 1992-2007, differently the prevalence observed between 1982-1992, this deficiency presents in high level, witch requires more effective measures of prevention and control.
评估巴西帕拉伊巴州儿童贫血的严重程度，分析其时间趋势，并调查与这种紊乱相关的因素。
对帕拉伊巴州1108名6至59个月大的儿童进行基于人群的横断面调查，涵盖男女。用自动计数器分析静脉血中的血红蛋白（Hb）。通过问卷获取儿童的社会经济和人口特征。采用Pearson卡方检验比较比例，用Poisson回归模型检验血红蛋白浓度与潜在危险因素之间的关联。通过贫血患病率的增加/减少评估贫血的时间趋势，并与1982年、1992年和2007年观察到的患病率进行比较。
帕拉伊巴州贫血（Hb < 11.0 g/dl）患病率为36.5%（95%置信区间33.7至39.3）。观察到1.3%（95%置信区间0.7至1.8）为重度贫血（Hb <7.0 g/dl），11%（95%置信区间9.4至13.5）为中度贫血，87.6%（95%置信区间79.1至91.2）为轻度贫血。1982 - 1992年间贫血病例增加了88.
