Workers more at risk of RA in certain occupations

Environmental factors are thought to be involved in triggering auto-immune reactions in people leading to the development of conditions such as rheumatoid arthritis. New research now indicates that there could be a raised risk of this for people working in certain occupations.

A study carried out at the Karolinska Institutet, Sweden, by Anna Llar and colleagues, looked at information on environmental, genetic and immunological factors collected between 1996 and 2014. The data was gathered from 3,522 people with RA and 5,580 controls.

Male workers in the manufacturing sector had a higher risk of developing RA than people working in a professional, administrative, or technical setting (reference group). A twofold increase in risk of developing RA was seen in male electrical and electronics workers along with material handling operators compared to the reference group. The risk was 3 times as much in bricklayers and concrete workers.

However, for women in the manufacturing sector, there was no increased risk (although this may be accounted for by the very low number of women in this area). Women working as assistant nurses and attendants did have a slightly increased risk.

The participants’ smoking habits, alcohol consumption, level of education and body mass index were all taken into account when analysing the results as these all play a factor in the risk of developing RA.

The results of this study indicate that work-related factors may potentially contribute to the development of RA, in particular, exposure to harmful airborne substances such as silica, asbestos, organic solvents and motor exhaust. However, more research needs to be done to identify specifically which of these is involved.

Once this is done, then employees and employers can make decisions to reduce the risk of developing RA by limiting the exposure to these factors.
