Mediterranean Diet May Reduce Risk of RA

Sep 15, 2020 12:34 am

Arthritis and Rheumatology reports that a Mediterranean diet (MD) is capable of reducing the high risk of RA among women who have smoked tobacco. 

The results stem from the E3N Study, a French prospective cohort study that collects dietary data on 98,995 women since 1990. An MD score was derived from standardized questionnaires.

From this population there were 480 incident cases of RA. Overall, the MD score was not associated with RA risk (HR: 0.86, 95% CI: 0.67 to 1.09) when comparing high MD to low MD scores.

However, among ever‐smokers, a high MD score was associated with a decreased risk of RA (HR for 1‐point increase of MD score: 0.91; 95% CI: 0.84 to 0.99, P = 0.03).

Amongst smokers, absolute risks of RA rose from 38.3/100,000 PYs to 51.5/100,000 person‐years when comparing high and low MD scores, respectively.

Adherence to a Mediterranean diet may reduce the risk of RA in high-risk candidates (women smokers).
