背景资料：贫血是一个全球性的公共卫生问题，影响到发展中国家和发达国家，对人类健康和社会经济发展造成重大后果。本文探讨血红蛋白浓度和贫血的严重程度与个人和家庭的特点，6-59个月的儿童在尼日利亚之间的可能关系，并探讨这些结果variables.Methods：血红蛋白浓度和贫血的严重程度在6-59个月的儿童参加了2010年尼日利亚疟疾指标调查的数据进行了分析。采用分层贝叶斯方法的半参数模型来检查不同类型协变量的推定关系和可能的空间变异。高斯，二进制和有序的结果变量被认为是modelling.Results：空间分析揭示了一个独特的南北划分Hb浓度的儿童分析和国家在北方尼日利亚具有较高的风险贫血。其他重要的风险因素包括家庭财富指数，儿童的性别，是否有发烧或疟疾的儿童在2周前的调查，和儿童24个月龄以下的结论：有必要为国家一级的具体方案，针对弱势儿童的实施，因为这可以帮助扭转现有的模式。
Background: Anaemia is a global public health problem affecting both developing and developed countries with major consequences for human health and socioeconomic development. This paper examines the possible relationship between Hb concentration and severity of anaemia with individual and household characteristics of children aged 6-59 months in Nigeria; and explores possible geographical variations of these outcome variables.Methods: Data on Hb concentration and severity of anaemia in children aged 6-59 months that participated in the 2010 Nigeria Malaria Indicator Survey were analysed. A semi-parametric model using a hierarchical Bayesian approach was adopted to examine the putative relationship of covariates of different types and possible spatial variation. Gaussian, binary and ordinal outcome variables were considered in modelling.Results: Spatial analyses reveal a distinct North-South divide in Hb concentration of the children analysed and that states in Northern Nigeria possess a higher risk of anaemia. Other important risk factors include the household wealth index, sex of the child, whether or not the child had fever or malaria in the 2 weeks preceding the survey, and children under 24 months of age.Conclusions: There is a need for state level implementation of specific programmes that target vulnerable children as this can help in reversing the existing patterns.
