In our data, appendectomy was reported by 6.3% of UC cases, 19.3% of CD cases, and 2.8% of non-IBD participants, and this difference was highly significant (χ2 = 26.9, p < 0.001).

Medical history variables were significantly related to IBD status included the presence of allergies (p = 0.005), history of appendectomy (p < 0.001), childhood antibiotic use before the age of 14 (p = 0.011), use of non-aspirin-non-steroidal anti-inflammatory drugs (NSAIDS) (borderline significant at p = 0.054), oral contraceptive use (p = 0.046), and prior parasitic infections (p = 0.020). all other exposures assessed did not demonstrate statistically significant associations.
Other exposures, including work stress, milk and fried food intake, frozen meals, oral contraceptive use, sleep duration, and delivery mode, did not reach statistical significance in the adjusted model.
