Results showed that women who were overweight or obese compared with women with normal weight have a higher rate of disease development of overweight in the future. Hazard ratio is a statistical term to describe an incident rate ratio at which the participants in the study group is developing RA. Women who are overweight with a BMI of 25 to 29.9, with an incidence of rheumatoid arthritis in the first group was 1.19 and 1.78 in the second group. Women who were overweight, with a BMI higher than 30, the prevalence of rheumatoid arthritis in the future are 1.18 and 1.73 in the two cohorts, respectively.

Thus, this study confirms the contribution of body weight affects rheumatoid arthritis in women and overweight and obesity in women is considered a cause of suffering from rheumatoid arthritis
