本文提出了一种识别全国老年双生子队列的方法。开发了记录链接算法，并将其应用于联邦医疗保险受益人文件中包含的3000万条记录。男性/男性配对的匹配算法使用了种族(黑人或白人)、姓氏、出生日期和社会保障号码的发放状态。女性/女性和男性/女性配对在种族、出生日期和社会保障号码的前七位数字上进行匹配，以弥补没有婚前姓氏的情况。分层随机抽取同性和异性白人和黑人对(6组)进行调查，以确定双胞胎的实际患病率。基于这些结果，作者得出结论，这种方法可以识别大约18308对男性/男性，7544对女性/女性，以及204对65岁或以上的男性/女性双胞胎。这将是美国有史以来收集到的最大的双胞胎样本，为老龄化人口的流行病学研究提供了重要的新资源。
In this paper, a method with which to identify a national cohort of elderly twins is proposed. Record linkage algorithms were developed and applied to the >30 million records contained in the Medicare beneficiary file. The matching algorithm for male/male pairs used race (black or white), last name, date of birth, and state of issuance of the Social Security number. Female/female and male/female pairs were selected with matching on race, date of birth, and the first seven digits of the Social Security number to compensate for the absence of maiden names. A stratified random sample of same-sex and opposrte-sex white and black pairs (six groups) were selected and surveyed for determination of the actual prevalence of twins. On the basis of these results, the authors conclude that this method could identify an estimated 18,308 male/male, 7,544 female/female, and 204 male/female pairs of twins aged 65 years or more. This would be the largest sample of older twins ever assembled in the United States and represents a significant new resource for epidemiologic studies of the aging population.Am J Epidemiol1997; 145: 175–83.
