Abstract

In a national study of the work environment, physical, and mental well-being of more than 2600 Swedish nurses, 30% reported having experienced violence at work. Possible association between violence and a range of occupational, demographic, and lifestyle characteristics were studied. Stepwise multiple linear and logistic regressions were used to further examine risk factors for violence. Occupational factors with significant correlations to workplace violence were nursing discipline (type of ward or facility), years of work experience, supervisory responsibilities, night work, work dissatisfaction, work-related musculoskeletal injury, and frequency of patient handling. Demographic/lifestyle factors related to violence were age, gender, smoking, coffee consumption at work, and use of alcohol to relax after work. The best fit linear regression model explained 17% of the variance in violence, 13%, of the variance in threat of violence. The logistic regression model confirmed an increased risk of violence and threats in psychiatric and geriatric settings. However, much remains unexplained about the aetiology of violencc in health carc settings. This report provides the basis for a pilot intervention study currently in progress.  相似文献

为了解社会工作目前的职业声望,本文通过问卷调查了作为社会先进群体的大学生对社工的职业声望评价。调查结果显示,大学生自身所持有的价值观、择业要求会影响对职业的评价,对社工本身的了解程度也是影响因素之一。笔者因此建议通过大力加强社工价值教育,扩大舆论宣传和提高社工福利等措施来提高社工的职业声望。  相似文献

A case–control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. Jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan–Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality.  相似文献

The use of critical effects in the determination of occupational exposure limits (OELs) in Sweden is subjected to a statistical study. Many of the present OELs are high in relation to known noeffect levels and effect levels, and the degree of protection has a surprisingly weak correlation with the seriousness of the adverse effect. Several proposals for improved procedures are put forward. One of these is to supplement the concept of critical effects with that of dominant effects. A dominant effect of a substance is a health effect that is at some concentration the most serious health effect.  相似文献

This is the first comprehensive study to explore the determinants of perceived sources of occupational stress among workers in the rapidly expanding Chinese offshore oil industry. In this study we surveyed 561 Chinese workers in a state-owned oil company using a questionnaire that measured occupational stress and Type A personality behaviour (TABP), social support and other socio-demographic data. Occupational stress was assessed by the Occupational Stress Scale, adapted from the questionnaire developed in previous studies (Cooper & Sutherland, 1987; Sutherland & Cooper, 1996). Using factor analyses, we identified nine sources of stress: 'interface between job and family/social life'; 'career and achievement'; 'safety'; 'management problems and relationship with workmates'; 'physical environment of workplace'; 'living environment'; 'managerial role'; 'ergonomics'; and 'organizational structure'. We performed hierarchical regression analyses on each source of stress with variables reflecting socio-demographic characteristics, TABP and social support. Better-educated workers perceived more stress from the interface between their job and family or social life and career achievement, but less stress from ergonomics. Type A workers perceived more stress from career achievement and the living environment. Social support was significantly associated with four sources of stress. Workers with different job titles perceived stress from different sources. Our findings imply that, in the stress management of offshore oil workers, different strategies and methods could be applied to different occupational groups, and to workers with different personalities and socio-demographic characteristics.  相似文献

This paper adjudicates between competing accounts of recent trends in the amount and patterning of occupational age segregation. These accounts rely on narratives about: (1) the decline of age-graded mobility, (2) the rise of occupational volatility, and (3) the existence of dual labor markets, in particular increasingly bimodal age distributions in low-skill occupations. Using new log-multiplicative models and related methods, the findings show that overall age segregation declined between 1950 and 1990, which is consistent with the decline of age-graded mobility. Among women, though not among men, the findings show increasingly bimodal age distributions in particular low-skill occupations, which is consistent with a dual labor market. Starting in 1990, age segregation increased among men and may have increased among women, which is consistent with the occupational volatility narrative.  相似文献

Several methods for analyzing data from mortality studies of occupationally or environmentally exposed cohorts are shown to be special cases of a single procedure. The procedure assumes a proportional hazards model for exposure effects and represents the log-likelihood kernel for the data as that of N independent Poisson variates, where N is the total number of person-units of mortality observation time in the study. It formalizes and justifies the epidemiological techniques of classifying deaths and person-months of study time into categories defined by exposure and other covariates, and of computing standardized mortality ratios and indirectly standardized death rates. Parameters representing exposure effects can be estimated by using standard software packages. Special cases and applications are described in the context of lung cancer mortality among U.S. uranium miners.  相似文献
