From: Abdominal obesity, gender and the risk of rheumatoid arthritis – a nested case–control study

   OR (95% CI)
With abdominal obesity Obesity (BMI ≥30 kg/m2) 2.66 (1.26, 5.64)
Not obesity (BMI <30 kg/m2) Reference
No abdominal obesity Obesity (BMI ≥30 kg/m2) 0.48 (0.05, 4.40)
Not obesity (BMI <30 kg/m2) Reference
  1. Sensitivity analysis of the association between obesity and the risk of onset of rheumatoid arthritis in individuals divided on presence/absence of abdominal obesity. Results from logistic regression models are presented adjusted for age, sex, year of examination, cohort, education and smoking habits. Abdominal obesity was defined as a waist circumference ≥102 cm (men) or ≥88 cm (women). Obesity was defined as body mass index (BMI) ≥30 kg/m2
