A positive tuberculin reaction, which indicates tuberculous infection, is known to correlate with increased rates of tuberculous disease, but current data concerning possible relationships with factors such as ethnic group, socioeconomic status, age, and sex are unpublished or unavailable. Current background rates of tuberculous infection are also generally not available, so that expected prevalence rates of tuberculous infection in urban areas have not been confidently established. In 1973/74, the New York City Health Code presented an opportunity to study these factors in more than 50,000 employees of the Board of Education. For the first time, a specific index was used to quantitate socioeconomic status. The relative effect of each of these variables on reactor rate was measured. It was found that tuberculous infection was related to race or ethnic group, socioeconomic status, age, and sex, in that order. The over-all data presented a recent picture of the prevalence of tuberculous infection in an urban population.
结核菌素反应呈阳性表明存在结核感染，已知其与结核病发病率的增加相关，但目前有关其与种族、社会经济地位、年龄和性别等因素可能存在的关系的数据尚未发表或无法获取。目前也普遍没有结核感染的背景率，因此城市地区结核感染的预期患病率尚未得到确切确定。1973/74年，纽约市卫生法规为研究教育委员会50000多名员工中的这些因素提供了一个机会。首次使用了一个特定指数来量化社会经济地位。测量了每个变量对反应率的相对影响。结果发现，结核感染与种族或民族、社会经济地位、年龄和性别依次相关。总体数据呈现了城市人口中结核感染患病率的最新情况。
