Summary
Brief summary (as posted)
Patients aged \>40 years who underwent elective colonoscopies were recruited from ten institutions. Patients with a history of colorectal cancer or long-term dietary interventions were excluded. Participants completed a food frequency questionnaire (FFQ) prior to endoscopy. FFQ data were analyzed using energy-, age-, sex-, and body mass index-adjusted models; the dietary supplemental omega-3 intake was analyzed separately. Colonoscopy outcome data, including the adenoma number, pathology, and location, were collected. Participants were stratified into omega-3 consumption quartiles to assess colorectal adenoma incidence trends using P for trend analysis.
