Abstract
OBJECTIVE: Physically demanding occupations have been associated with becoming a disability pensioner with rheumatoid arthritis (DPRA), but not with the disease of RA. The association with becoming DPRA probably reflects that patients with RA have difficulties in maintaining employment in a physically demanding occupation. However, the attitudes of the employers concerning employment of persons with RA might vary. For example, the patient's age may influence the strength of the association between a physically demanding occupation and becoming DPRA. We assessed whether the association between the predictors and becoming DPRA was stronger for the youngest or the oldest age group. METHODS: The study was prospective with data on persons in Norway 30-56 years old either in the census of 1970 or 1980. All new cases of DPRA during the 2 followup periods 1971-80 and 1981-90 were identified and analyzed by logistic regression. RESULTS: For women the predictors employment, low level of education, and period ( 1981-90 compared to 1971-80) were more strongly associated with becoming DPRA for the youngest compared to the oldest persons, while manual work and part time work were not predictors of becoming DPRA. For men, all the predictors in the study were more strongly associated with becoming DPRA for the youngest compared to the oldest age group. CONCLUSION: The higher risk of becoming DPRA was associated with most predictors for persons aged 30-39 years than the group aged 50-56 years. Our results appear to indicate that the consequences of having RA in the labor market are greater for the youngest age group.
