We studied tuberculin skin test conversions in a cohort of 550 new employees followed for five years after assignment to adult inpatient services at Charity Hospital at New Orleans, Louisiana. There were 17 known conversions, an overall five-year cumulative probability of converting of 5.2 per cent. Proportional hazards regression analysis found that race and type of job (nursing vs other) were independent explanatory variables. To examine further the job effect, we compared the conversion curves for Blacks in nursing and Blacks in other jobs and found those in nursing to have higher rates.
我们对路易斯安那州新奥尔良慈善医院550名新员工组成的队列进行了研究,这些员工被分配到成人住院服务部门后随访了五年。已知有17例结核菌素皮肤试验阳转,总体五年阳转累积概率为5.2%。比例风险回归分析发现,种族和工作类型(护理与其他)是独立的解释变量。为了进一步研究工作的影响,我们比较了从事护理工作的黑人与从事其他工作的黑人的阳转曲线,发现从事护理工作的黑人阳转率更高。
