ABSTRACT Diarrhea is a major contributor to child morbidity and mortality in West Africa. Non-spatial regression and geographically weighted Poisson regression applied to data from 10 Demographic and Health Surveys conducted in West Africa from 2008 to 2013 show that water source, toilet type, mother’s education, latitude, temperature, rainfall, altitude, and population density influence the risk of diarrhea. The risk associated with these factors is dependent on location and may be higher or lower than the rest of the study area. Areas with increased relative risk for diarrhea include several urban centers, low-elevation areas (coastal and along rivers), remote areas such as western Mali, and conflict zones (northeast Nigeria).

2008-2013 年西非危险因素与儿童腹泻之间的空间变化关系

摘要 腹泻是西非儿童发病率和死亡率的主要原因。非空间回归和地理加权泊松回归应用于 2008 年至 2013 年在西非进行的 10 次人口和健康调查的数据表明，水源、厕所类型、母亲的教育、纬度、温度、降雨量、海拔和人口密度影响腹泻的风险。与这些因素相关的风险取决于位置，并且可能高于或低于研究区域的其余部分。腹泻相对风险增加的地区包括几个城市中心、低海拔地区（沿海和河流沿岸）、马里西部等偏远地区和冲突地区（尼日利亚东北部）。
