Meta-analysis is increasingly appearing in the epidemiologic literature. Although originally performed in the context of experimental or randomized controlled study designs and with regard to problems that are amenable to these designs, the method has also been applied to studies in observational epidemiologic settings. This movement has generated considerable debate about the validity of meta-...

Correspondence to: Prof. T S Kristensen, National Institute of Occupational Health, Lerso Parkalle 105, DK-2100 Copenhagen O, Denmark; [email protected] _________________________ T he proportion of intervention studies in occupational epidemiology has been growing rapidly in recent years. This is a positive trend, which makes it necessary to discuss a number of theoretical, methodological, and practic...

The data summarized in this section are taken mainly from the 2000 Report of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and generally refer to occupational exposures assessed to have been experienced during the earlyand mid-1990s [1]. Occupational exposures in the United Kingdom from 1998 to 2003 have been reviewed recently by the Radiation Protection ...

Complex and dynamic physiologic processes underlie the exposure-response relations that occupational and environmental epidemiologists study. Simple summary measures of exposure such as the average, cumulative exposure, or duration of exposure, can be applied suitably in exposure-response analyses in many instances. However, there are situations where these metrics may not be directly proportio...

With the accelerating pace of new knowledge about occupational asthma, systematic epidemiological approaches have yielded important new insights into its clinical characteristics. Such questions as "what proportion of all cases of asthma are caused by occupational exposures?" and "is occupational asthma incidence rising?" can now be answered. Surveillance programmes estimate the number of expos...

BACKGROUND The study of the influence of life course occupational position (OP) on health in old age demands analysis of time patterns in both OP and health. We study associations between life course time patterns of OP and decline in grip strength in old age. METHODS We analyze 5 waves from the Survey of Health Ageing and Retirement in Europe (n = 5108, ages 65-90). We use a pattern-mixture ...

Objective The aim of this study was to describe the application of latent class growth analysis (LCGA) to identify different working life trajectories (WLT) using employed working time by year as a repeated measure. Methods Trajectories are estimated using LCGA, which considers all individuals within a trajectory to be homogeneous. The methodology was applied to a subsample of the Spanish WORKi...

We are fortunate in having a number of sources for reconstructing the epidemiology of occupational diseases in pharaonic Egypt and the religious, magical, and medical means of treatment available to workmen engaged in various projects and tasks. In addition to the inscriptions which the leaders and personnel of official expeditions often left in the desert,1 we have a rich collection of records...
