In Peru, anemia affects around 30% of children under the age of four, making it one of the major public health problems of the country. The literature suggests that water, sanitation, and hygiene (WASH) conditions may reduce anemia prevalence; however, empirical evidence of this association remains scarce for the Peruvian context. The objective of this study was to analyze the association between WASH conditions and office visits due to anemia (OVA), at the regional level during the years 2010–2018. Using generalized estimating equation models (GEE), we find that the prevalence of OVA increases by 0.24/1,000 per one percentage point (PP) increase in the proportion of households with access to safe drinking water and decreases by 0.22/1,000 per one PP increase in the proportion of households with basic sanitation. Our results suggest that policymakers should not only ensure a better coverage of drinking water sources but also ensure adequate quality.

在秘鲁，贫血影响了大约30％的四岁以下儿童，这使其成为该国主要的公共卫生问题之一。文献表明，饮水，环境卫生和个人卫生（WASH）条件可能会降低贫血患病率。但是，对于秘鲁而言，这种联系的经验证据仍然很少。这项研究的目的是在2010-2018年期间分析WASH条件与因贫血引起的办公室就诊（OVA）之间的关联。使用广义估计方程模型（GEE），我们发现，获得安全饮用水的家庭比例中，OVA的患病率每增加一个百分点（PP）增加0.24 / 1,000，而每增加一个PP则减少0.22 / 1,000在拥有基本卫生设施的家庭中所占的比例。
