In 1982 and 1983, brief, structured performance tests of selected areas of cognitive function were administered to 3,682 (82.1 per cent) of the residents aged 65 years and older of the geographically defined community of East Boston, Massachusetts, a center of the Established Populations for Epidemiologic Studies of the Elderly program. There was a strong inverse relation between age and performance on all four cognitive tests in analyses adjusted for sex only as well as in those adjusted for the effects of other variables. Similarly, fewer years of formal education, increasing level of disability on the modified Katz Activities of Daily Living Scale, and less prestigious occupations, as measured by the modified Duncan Socioeconomic Index, were each independently related to lower performance on all four tests.
1982年和1983年，对马萨诸塞州东波士顿地理界定社区中3682名（82.1%）65岁及以上的居民进行了特定认知功能领域的简短、结构化表现测试，该社区是老年流行病学研究既定人群项目的一个中心。在仅针对性别进行调整的分析以及针对其他变量影响进行调整的分析中，年龄与所有四项认知测试的表现之间均存在强烈的负相关关系。同样，受教育年限越少、根据改良的卡茨日常生活活动量表衡量的残疾程度增加以及根据改良的邓肯社会经济指数衡量的职业声望越低，在所有四项测试中均各自独立地与较低表现相关。
