Abstract
Mortality was investigated for the years 1950–1980 for 1,009 male members of a New York jewelry workers union, and for the years 1984–1989 among 919 men and 605 women identified as jewelry workers on death certificates from 24 states. Malignant neoplasms were excessive for male union members (proportional mortality ratio [PMR] = 1.17; 95% confidence interval [CI]: 1.02–1.33) and female jeweler deaths from the 24 states (PMR = 1.24; 95% CI: 1.07–1.42). Deaths due to nonmalignant causes were not unusual, except for excesses, in union males, of the circulatory system (PMR = 1.10; 95% CI: 1.02–1.19), including arteriosclerotic heart disease (PMR = 1.25; 95% CI: 1.14–1.37) and rheumatic heart disease (PMR = 3.02; 95% CI: 1.94–4.50). Cancers of the digestive tract were proportionally elevated among union males (proportional cancer mortality rate [PMR] = 1.13; 95% CI: 0.89–1.41) and among deaths from the 24 states (PCMR = 1.22; 95% CI: 1.01–1.47). For the 24 states, excesses for digestive cancer were found for both males (PCMR = 1.19; 95% CI: 0.90–1.54) and females (PCMR = 1.26; 95% CI: 0.96–1.62). Regarding specific sites in the digestive tract, colon cancer excesses were found in union males (PCMR = 1.53: 95% CI: 1.05–2.15), and for men (PCMR = 1.27; 95% CI: 0.82–1.88) and women (PCMR = 1.36; 95% CI: 0.92–3.27) in 24 states. Also, in the 24 states, excesses were noted for esophageal cancer (PMR = 2.03; 95% CI: 1.08–3.47) and stomach cancer (PCMR = 1.66; 95% CI: 0.95–2.69), due to excess stomach cancer in women (PCMR = 2.50; 95% CI: 1.20–4.61). Marginal proportional excesses were found for malignancies of the hematolymphopoietic system in union males (PCMR = 1.12; 95% CI: 0.72–1.67) and among deaths from 24 states (PCMR = 1.23; 95% CI: 0.90–1.66), particularly due to non‐Hodgkin's lymphoma deaths (PCMR = 1.39; 95% CI: 0.93–2.00). The wide variety of exposures in this industry, particularly to metals and solvents, could possibly involve excess risk for malignancy at these sites. © 1993 Wiley‐Liss, Inc.†
