Abstract
BACKGROUND: To investigate prospective association of coffee and tea intake with incident irritable bowel syndrome (IBS) in a long-term cohort.</p>
METHODS: Participants free of IBS, coeliac disease, inflammatory bowel disease and any cancer at baseline from UK Biobank were included. Coffee and tea intake was measured separately via baseline touchscreen questionnaire, with four categories for each intake (0, 0.5-1, 2-3 and ≥4 cups/day). Primary outcome was incident IBS. Cox proportional hazard model was used to estimate associated risk.</p>
RESULTS: Among 425 387 participants, 83 955(19.7%) and 186 887(43.9%) consumed ≥4 cups/day of coffee and tea at baseline, respectively. During median 12.4-year follow-up, incident IBS was identified in 7736 participants. Compared with no coffee intake, consumption of 0.5-1, 2-3 and ≥4 cups/day was associated with lower IBS risk [hazard ratio (HR)=0.93, 95% CI: 0.87-0.99; 0.91, 0.85-0.97; 0.81, 0.76-0.88; Ptrend < 0.001]. Specifically, decreased risk was evident in individuals who consumed instant (HR = 0.83, 0.78-0.88) or ground coffee (HR = 0.82, 0.76-0.88) compared with no coffee drink. Regarding tea intake, protective association was only found in individuals who consumed 0.5-1 cup/day (HR = 0.87, 0.80-0.95), whereas no significant association was detected in those who consumed 2-3 (HR = 0.94, 0.88-1.01) or ≥4 cups/day (HR = 0.95, 0.89-1.02) compared with no-tea intake (Ptrend = 0.848).</p>
CONCLUSIONS: Higher intake of coffee, particularly instant and ground coffee, is associated with lower risk of incident IBS, with significant dose-response relationship. Moderate-tea intake (0.5-1 cup/day) is associated with lower IBS risk.</p>
