Background. Extensive studies have been carried out to investigate the association between obesity and the risk of rheumatoid arthritis (RA); however, the results of the current reported original studies remain inconsistent. This study aimed to clarify the relationship between body mass index and rheumatoid arthritis by conducting an updated overall and dose-response meta-analysis. Methods. The relevant literature was searched using the PubMed and Embase databases (through 20 September 2018) to identify all eligible published studies. Random-effect models and dose-response meta-analyses were used to estimate the pooled risk ratio (RR) with a 95% confidence interval (CI). Subgroup analyses were also conducted based on the characteristics of the participants. Sensitivity analyses and publication bias tests were also performed to explore potential heterogeneity and bias in the meta-analysis. Results. Sixteen studies that included a total of 406,584 participants were included in the meta-analysis. Compared to participants with normal weight, the pooled RRs of rheumatoid arthritis were 1.12 (95% CI, 1.04-1.20) in overweight and 1.23 (95% CI, 1.09-1.39) in obese participants. There was evidence of a nonlinear relationship between body mass index (BMI) and RA (P  for nonlinearity less than 0.001 in the overall meta-analysis, P for nonlinearity=0.025 in the case-control studies, P for nonlinearity=0.0029 in the cohort studies). No significant heterogeneity was found among studies (I2=10.9% for overweight and I2=45.5% for obesity). Conclusion. The overall and dose-response meta-analysis showed that increased BMI was associated with an increased risk for rheumatoid arthritis, which might present a prevention strategy for the prevention or control of rheumatoid arthritis. The nonlinear relationship between BMI and RA might present a personal prevention strategy for RA.

7060 Background: The obesity paradox –i.e. inverse associations between body mass index (BMI) and mortality – has been reported in patients with cancer, heart failure, and diabetes. However, the influence of cardiorespiratory fitness (CRF) on this relationship is not well established. This study assesses the association of BMI and CRF with all-cause mortality among cancer patients. Methods: The Henry Ford (HF) FIT Project is a retrospective cohort study of 69,885 consecutive patients who underwent physician-referred exercise stress testing from 1991 through 2009. Cancer diagnosis was identified through linkage to the HF tumor registry. We included patients 40-70 years old, with BMI recorded, at time of exercise test, with a history of cancer > 6 months prior. BMI was categorized as normal (18.5-24.9kg/m2), overweight (25-29.9kg/m2), or obese ( > = 30kg/m2). All-cause mortality was obtained from the National Death Index. Because of a significant interaction between BMI and cancer type, patients with breast or prostate cancer were excluded. Multivariable adjusted Cox proportional hazard models were used to evaluate the association of CRF andBMI with all-cause mortality; adjusted for age at exercise test, sex, diabetes, smoking, cancer stage, and time from cancer diagnosis to exercise test. Results: Included were 676 patients with a mean age of 58 years (SD 7.5), 51% female, 70% White, 25% Black, with a median of 4.8 years from diagnosis to exercise test and median follow up time of 10.3 years. Among patients achieving < 10 METs, those who are overweight and obese had a lower risk of mortality HR 0.47 (95% CI 0.25,0.86) and HR 0.44 (95% CI 0.26, 0.74, respectively), compared to those with normal BMI. Among patients with METs > = 10, those who were overweight had the lowest risk of all-cause mortality (HR 0.23, 95% CI 0.09-0.62) compared to normal weight, while no statistically significant different risk of mortality was observed when comparing those who are obese to normal weight (HR 0.37, 95% CI 0.13-1.06). In an analysis combining BMI and fitness groups (four categories), those with BMI > = 25 and METs > = 10 had the lowest risk of all-cause mortality (Table). Conclusions: In non-breast/non-prostate cancer patients, increased BMI is associated with improved overall survival in those with METs < 10, while a U-shaped relationship between BMI and all-cause mortality exists among those with METs > = 10.
