Omega-3 Fatty Acid and Colorectal Adenoma

May 23, 2024 updated by: Sang Hoon Kim, DongGuk University

Omega-3 Fatty Acid Intake and Risk of Colorectal Adenoma

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.
