MORTALITY OF A POLICE COHORT - 1950-1990

This study presents findings from an updated retrospective cohort mort ality study of male police officers from January 1, 1950 to December 3 1, 1990 (n = 2,593; 58,474 person-years; 98% follow-up). Significantly higher than expected mortality rates were found for all cause mortali ty (Standardized mortality ratio [SMR] = 110; 95% confidence interval [95% CI] = 1.04-1.17), all malignant neoplasms (SMR = 125; 95% CI = 1. 10-1.41), cancer of the esophagus (SMR = 213; 95% CI = 1.01-3.91), can cer of the colon (SMR = 187; 95% CI = 1.29-2.59), cancer of the kidney (SMR = 208, 95% CI = 1.00-3.82), Hodgkin's disease (SMR = 313; 95% CI = 1.01-7.29), cirrhosis of the liver (SMR = 150; 95% CI = 1.00-2.16), and suicide (SMR = 153; 95% CI = 1.00-2.24). All accidents were signi ficantly lower (SMR = 53; 95% CI = 0.34-0.79). Mortality by years of p olice service showed higher than expected rates for (1) all malignant neoplasms in the 1- to 9-years-of-service group; (2) all causes, bladd er cancel; leukemia, and arteriosclerotic heart disease in the 10 to 1 9-year group; and (3) colon cancer and cirrhosis of the liver in the o ver 30 years of service group. Hypotheses for findings are discussed. (C) 1998 Wiley-Liss, Inc.
