XXXX in U.S. Navy personnel.

@entity1893 @entity1 @entity5
@entity1893 are one of the most commonly occurring @entity5 in the age groups heavily represented in the U.S. Navy. The Navy has a wide range of potential occupational exposures. This study was initiated to identify any occupational associations of @entity1893 that may adversely affect naval readiness. The objective of this study was to compare the incidence of @entity1893 in U.S. Navy active duty enlisted personnel during the period 1974-1983 with the general U.S. population, and to assess if risk varied by naval occupation or length of service. The Naval Health Research Center's computer-based disease registry was used to conduct a prospective study of all white U.S. Navy enlisted @entity1 during 1974-1983 to test for the existence of any short-term risk possibly due to occupation. @entity1 in 80 occupations, ranging from clerk to journalist to machinist and boiler operator were observed for 3,704,864 @entity1 -years; mean length of service was 5.1 yr, but 19% of @entity1 -years were contributed by @entity1 who had served at least 11 yr. Incident cases of @entity1893 were identified and verified using Medical Board findings or review of original medical records. Average annual age-specific and age-adjusted incidence rates were calculated. Examination of pathology records and medical review boards confirmed 68 cases of @entity1893 . The annual age-adjusted incidence rate per 100,000 @entity1 -years in Navy @entity1 was significantly lower than in the U.S. Surveillance, Epidemiology, and End Results (SEER) population, probably due to screening and other selection factors associated with Navy service that result in a healthy worker effect.(ABSTRACT TRUNCATED AT 250 WORDS)
