论文摘要
在流行病学研究中通常不会收集有关邻里特征的数据。但是，它们在研究小区域健康不平等的研究中很有用。在某些调查中收集了邻里特征，可以与其他研究的数据相关联。我们建议使用基于半百万分学模型的kriging来预测非观察到的位置的值，以构建邻里特征的定制指数，该指数与流行病学研究中的数据相关联。我们进行了一项模拟研究，以评估该方法的可行性以及使用记录研究中数据的案例研究。除了有足够的观察到的数据在与非观察到的位置的较小距离之外，良好的拟合半变量图，较大的范围以及半变量图模型的块状效应的缺失是导致更高可靠性的因素。
Data on neighbourhood characteristics are not typically collected in epidemiological studies. They are however useful in the study of small-area health inequalities. Neighbourhood characteristics are collected in some surveys and could be linked to the data of other studies. We propose to use kriging based on semi-variogram models to predict values at non-observed locations with the aim of constructing bespoke indices of neighbourhood characteristics to be linked to data from epidemiological studies. We perform a simulation study to assess the feasibility of the method as well as a case study using data from the RECORD study. Apart from having enough observed data at small distances to the non-observed locations, a good fitting semi-variogram, a larger range and the absence of nugget effects for the semi-variogram models are factors leading to a higher reliability.
