ABSTRACT To explore, using recent data, whether and how risk factors for rheumatoid arthritis (RA) work disability may differ from previous studies.
Subjects were 953 individuals with RA from a US cohort who provided data semiannually over 18 months (years 2002-2005). A nested case-control design was used with matching on time of baseline data collection. All subjects were employed at baseline; cases were consistently not employed at followup, whereas controls remained employed. Hierarchical conditional logistic regression assessed the roles of demographic, RA disease, general health, and work factors as predictors of work disability. Recursive partitioning and causal modeling procedures were also used.
Sample characteristics were mean age 51 years, 82% female, and 92% white. Older age (odds ratio [OR] 1.2, 95% confidence interval [95% CI] 1.1-1.4) and lower income (OR 1.7, 95% CI 1.0-2.7) predicted work disability, whereas more hours worked (OR 0.9, 95% CI 0.8-0.9) and preference to work full time (OR 0.2, 95% CI 0.1-0.4) or part time (OR 0.4, 95% CI 0.2-0.6) versus not to work were protective in the regression analysis. In recursive partitioning analyses, RA disease factors predicted work disability among older subjects, and functional limitation was the fourth most important factor. Job physical demand was not a significant or important factor.
In this contemporary data from a large RA cohort, older age, lower income, fewer working hours, and preference not to work were the risk factors for work disability. The impact of disease factors was limited to subjects ages >or=56 years. Job physical demand level had little impact.

    ABSTRACT: The aim of this review is to describe aspects of vocational rehabilitation relevant for a physician aiming to become a specialist in physical and rehabilitation medicine (PRM). The review discusses the epidemiology of incapacity for work, the major patient groups in vocational rehabilitation (musculoskeletal and psychiatric diagnoses comprise approximately 50-70% of the patients), the influence of different kinds of environmental and individual risk factors on work resumption (such as the legal framework, application of the law, resources for rehabilitation and its effectiveness, the degree of co-operation between vocational rehabilitation agencies, economic factors/labour market situation, medical and personal factors). The review describes different models of vocational rehabilitation, the effectiveness of various vocational rehabilitation programmes on work resumption or sick leave (where strong evidence is reported for multi-modal rehabilitation programmes for patients with long-lasting musculoskeletal pain). Finally, there are sections about the PRM physician's history-taking in vocational rehabilitation (using the International Classification of Functioning, Disability and Health (ICF)), and report writing with a structure where ICF body functions and activity limitations are reported separately.

    ABSTRACT: Young adults in the early stages of their participation in the labour market may be particularly vulnerable to the effects of onset of a chronic disease. Our aim was to quantify the consequences of the onset of type 1 diabetes in young adults on annual earnings, using individual-level longitudinal data before and after the onset of diabetes. The Econ-DISS database contains annual socioeconomic information for 1990-2005 from Statistics Sweden. Econ-DISS includes data for persons with diabetes onset at the age of 15-34 years between 1983 and 2005, registered in the national Diabetes Incidence Study in Sweden (DISS) database, and for controls. Considering the onset of type 1 diabetes as an unanticipated and significant life event, we compared the progression of annual earnings for 3,650 cases born between 1949 and 1970 before and after onset of diabetes with that of 14,629 controls. Possible confounders--education, participation in the labour market, sick leave and parental education--were analysed. We found no differences between the groups in annual earnings or participation in the labour market before onset of diabetes. After onset, persons with type 1 diabetes gradually lagged behind the controls. Their median annual earnings were lower in each year from 1995 to 2005 (p < 0.01). The difference in 2005 was euro (EUR) 1,411 (5.3%). Controlling for confounders, duration of type 1 diabetes > or = 10 years was associated with 4.2% (men) and 8.1% (women) lower average annual earnings for persons with upper secondary education only who were active in the labour market. The onset of type 1 diabetes in young adults has long-term detrimental consequences on earnings that cannot be attributed to confounders.
