摘要:

Automated blood pressure devices are available in a growing number of shopping malls, drug stores and workplaces. This study evaluates behavior changes that occurred in employees who used these devices to self-monitor blood pressure at work. A cohort design with a nonequivalent control group was used to study blue-collar hospital employees. Experimental participants (N=91) had daily access to a Vita Stat automated blood pressure device while controls (N=102) did not. Life-style scores included one point for each of five risk-reducing behaviors. Experimentals who self-monitored at least weekly showed significant increases in life-style scores. The proportion of this group practicing at least three of five of the recommended behaviors Increased from 56% at baseline to 76% at the four-month and 88% at the 12-month follow-up (p <.001). Scores for experimentals who self-monitored less than weekly and for controls remained unchanged during the same period. These results suggest that weekly blood pressure self-monitoring at work is associated with improvements in life-style behaviors related to smoking, exercise, sodium restriction, and dieting.

摘要:

This retrospective study was undertaken to determine the incidence of acute and chronic morbidity due to hepatitis B infection among employees of an institution for the mentally retarded. Based on a review of medical records, surveillance data, and serologic testing, we found no evidence of excess morbidity among 2,000 employees in a 10-year period. Hepatitis B vaccination is neither warranted nor presently cost-effective for most client-care personnel.

摘要:

The purpose of this study was to investigate the pathological influence of mechanical stresses that occur Inside the carpal tunnel during exertions of the hand. Microscopic changes in fibrous tissue density, in synovial, subsynovial, and adjacent connective tissue density, and in median nerve epineurium density, arteriole wall muscle thickness, and arterial and venule endoproliferation were investigated at 5-mm increments along a 9-cm range of six postmortem wrist specimens. All of these changes increased from normal in the proximal portions of the wrist, −30 to −40 mm from the wrist crease, to maximal values 0− to 20-mm distal to the wrist crease. The changes then decreased toward normal In the distal sections, 20 to 40 mm. The location and character of these changes suggest that repeated exertions with a flexed or extended wrist are an important factor in their etiology. The consistency with which they are found in this and other studies suggests that extreme changes associated with highly repetitive work or additional stress factors are required to produce symptoms in most cases of carpal tunnel syndrome.

摘要:

Over 94% of the workers in each of four Saskatchewan potash mines participated in a respiratory health surveillance program that included a questionnaire and pulmonary function tests. Compared with a nonexposed control group, potash workers had higher prevalences of cough, dyspnea, and chronic bronchitis but better pulmonary function. Prevalences of symptoms and pulmonary function abnormalities were similar among workers at the four mines tested and at the various job locations. Potash dust, diesel fumes, and other air contaminants may have an irritant effect that leads to the increased prevalences of cough and chronic bronchitis. Although we found no adverse effects of the potash mine environment on pulmonary function, these findings reflect a healthy worker effect or some selection process that makes the potash workers appear healthier in a cross-sectional study.

摘要:

The objective of this study was to examine the cause-specific mortality experience of white male employees from 10 assembly plants of five participating companies. Proportionate mortality ratio (PMR) analyses carried out using both national and local standards of comparison yielded similar results. Statistical significance of PMRs was assessed using the Mantel-Haenszel procedure. Statistically significant PMRs were observed for several causes of death when results for all plants were combined. However, the pattern of significant PMRs observed when results were analyzed separately by company and plant suggests that potential increases in risk for any individual cause of death are limited to no more than two companies and are not observed throughout the industry.
