Alcohol consumption reduces risk of rheumatoid arthritis: Study

March 31, 2016

It is not fully understood why drinking alcohol should reduce the severity of RA and people's susceptibility to developing it. "There is some evidence to show that alcohol suppresses the activity of the immune system, and that this may influence the pathways by which RA develops. We do know that the changes in the immune system that lead to RA happen months and maybe even years before the arthritis actually develops," said Dr Maxwell. "Once someone has developed RA, it's possible that the anti-inflammatory and analgesic effects of alcohol may play a role in reducing the severity of symptoms.

"Further research is needed to confirm the results of our study and to investigate the mechanisms by which alcohol influences people's susceptibility to RA and the severity of symptoms. It is also possible that different types of alcoholic drinks may have different effects on RA."

The authors point out that there are some limitations to their study. These include the fact that they only recorded the frequency rather than the amount of alcohol consumption in the month before people joined the study; there might be bias due to people recalling inaccurately how often they drank alcohol and also the information represents a snapshot of drinking behaviour at one point in time, rather than giving information about fluctuating alcohol consumption over a longer period; and, finally, there were marked differences in age and gender between the RA and the control groups, although the researchers did adjust their results for these factors.
