This cross-sectional population-based study investigated prevalence rates and associated factors for anemia, iron deficiency anemia, and iron deficiency among children 6 to 60 months of age in two towns in Acre State, Brazil (N = 624). Hemoglobin, plasma ferritin, and soluble transferrin receptor were measured in venous blood samples. Socioeconomic, demographic, and disease data were obtained using a questionnaire. Prevalence ratios were calculated by Poisson regression in a hierarchical model. Prevalence rates for anemia, iron deficiency anemia, and iron deficiency were 30.6%, 20.9%, and 43.5%, respectively. Children younger than 24 months showed higher risk of anemia, iron deficiency anemia, and iron deficiency. The highest family income tertile was a protective factor against iron deficiency anemia (PR: 0.62; 95%CI: 0.40-0.98). The highest height-for-age quartile was protective against anemia (0.62; 0.44-0.86) and iron deficiency anemia (0.51; 0.33-0.79), and recent history of diarrhea was associated with increased risk of anemia (1.47; 1.12-1.92) and iron deficiency anemia (1.44; 1.03-2.01). Geohelminth infection was associated with increased risk of anemia, iron deficiency anemia, and iron deficiency.
这项基于人群的横断面研究调查了巴西阿克里州两个城镇6至60个月大儿童贫血、缺铁性贫血和缺铁的患病率及相关因素（N = 624）。采集静脉血样测量血红蛋白、血浆铁蛋白和可溶性转铁蛋白受体。通过问卷调查获取社会经济、人口统计学和疾病数据。在分层模型中通过泊松回归计算患病率比值。贫血、缺铁性贫血和缺铁的患病率分别为30.6%、20.9%和43.5%。24个月以下的儿童患贫血、缺铁性贫血和缺铁的风险更高。家庭收入最高三分位数是缺铁性贫血的保护因素（PR：0.62；95%CI：0.40 - 0.98）。年龄别身高最高四分位数对贫血（0.62；0.44 - 0.86）和缺铁性贫血（0.51；0.33 - 0.79）有保护作用，近期腹泻史与贫血（1.47；1.12 - 1.92）和缺铁性贫血（1.44；1.03 - 2.01）风险增加有关。土源性蠕虫感染与贫血、缺铁性贫血和缺铁风险增加有关。
