This exploratory study examined the mortality experience of a cohort of newspaper printers in order to investigate the effects of low-level exposure to lead. In this industry, historic lead exposure levels have been below the current US permissible exposure level (PEL) of 50 micrograms/m3. The study population was 1261 typesetters, employed in 1961 and(More)
A proportionate analysis of cause of death in 1,401 commercial pressmen was initiated following a report of a cancer cluster in this group. The study found a significant elevated risk of all cancers [proportionate mortality ratio (PMR) = 127] and cancers of the lymphatic and hematopoietic system (PMR = 122), with non-Hodgkin's lymphomas responsible for much(More)
Data from three cross-sectional samples of inmates in the New York City correctional system (N = 299, 236, and 151) were analyzed to determine the prevalence of homelessness among detainees. One-fourth to one-third of each sample had been homeless at some time during the two months before arrest, and 20 percent of the primary sample of 299 inmates had been(More)

We have investigated the establishment and maintenance of compliance with isoniazid prophylaxis in this population. Factors affecting compliance were(More)
The results of a proportional mortality analysis of a cohort of sheet metal workers who have only intermittent exposure to asbestos demonstrates a significant excess of cancer at the three sites most frequently associated with asbestos: lung, colon and rectum, and the mesothelium. No excess nonmalignant respiratory disease was detected. These data strongly(More)
