We previously developed and validated an index of socioeconomic status (SES) termed HOUSES (housing-based index of socioeconomic status) based on real property data. In this study, we assessed whether HOUSES overcomes the absence of SES measures in medical records and is associated with risk of invasive pneumococcal disease (IPD) in children. We conducted a population-based case-control study of children in Olmsted County, MN, diagnosed with IPD (1995-2005). Each case was age- and gender-matched to two controls. HOUSES was derived using a previously reported algorithm from publicly available housing attributes (the higher HOUSES, the higher the SES). HOUSES was available for 92·3% (n = 97) and maternal education level for 43% (n = 45). HOUSES was inversely associated with risk of IPD in unmatched analysis [odds ratio (OR) 0·22, 95% confidence interval (CI) 0·05-0·89, P = 0·034], whereas maternal education was not (OR 0·77, 95% CI 0·50-1·19, P = 0·24). HOUSES may be useful for overcoming a paucity of conventional SES measures in commonly used datasets in epidemiological research.
我们之前基于房地产数据开发并验证了一种社会经济地位（SES）指数，称为 HOUSES（基于住房的 SES 指数）。在这项研究中，我们评估了 HOUSES 是否可以弥补医疗记录中 SES 衡量指标的不足，并与儿童侵袭性肺炎球菌病（IPD）的风险相关。我们对明尼苏达州奥姆斯特德县的儿童进行了一项基于人群的病例对照研究，这些儿童被诊断患有 IPD（1995-2005 年）。每个病例都与两个对照按年龄和性别匹配。HOUSES 是使用先前报告的从公开可用的住房属性中得出的算法得出的（HOUSES 越高，SES 越高）。HOUSES 可用于 92.3%（n=97）的病例和 43%（n=45）的母亲教育水平。在未匹配分析中，HOUSES 与 IPD 的风险呈负相关[比值比（OR）0.22，95%置信区间（CI）0.05-0.89，P=0.034]，而母亲教育水平则没有（OR 0.77，95% CI 0.50-1.19，P=0.24）。HOUSES 可能有助于克服在流行病学研究中常用的数据集缺乏传统 SES 衡量指标的问题。
