Objectives

Diet has been shown to be associated with rheumatoid arthritis (RA), and magnesium has been shown to inhibit inflammatory responses, but research on the relationship between dietary magnesium and RA is limited and controversial. In this study, we aimed to explore the non-linear relationship between dietary magnesium intake and RA in US women.

Design

Cross-sectional survey.

Setting

National Health and Nutrition Examination Survey (NHANES).

Primary and secondary outcome measures

Non-linear relationship between dietary magnesium intake and prevalence of RA.

Participants

A total of 13 324 women aged 18-80 years (RA n=12 306, non-RA n=1018) were included in this study.

Results

Overall, the absolute risk (AR) of RA was 7.24% in all participan
