Social isolation was assessed using household size, social contact frequency, and weekly social activities, while loneliness was measured by self-reported feelings of loneliness and willingness to confide. The primary outcome was incident IBS. Cox regression with sequential mediation analysis was conducted to estimate the effect.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>During a median follow-up of 14.5\u2009years, 8307 (2.1%) incident IBS cases were identified. Overall, 209,081 (53.0%), 149,729 (38.0%), and 35,648 (9.0%) participants were classified as least, moderately, and most isolated, respectively. The 14-year cumulative incidence of IBS increased from 2.0% (95% confidence interval (CI): 2.0\u20132.1) in the least isolated group to 2.2% (95% CI: 2.2\u20132.3) and 2.6% (95% CI: 2.4\u20132.8) in the moderately and most isolated groups (population-attributable fraction (PAF)\u2009=\u20093.6%). Compared with the least isolated group, most isolated individuals had a 20.0% higher IBS risk (hazard ratio (HR)\u2009=\u20091.20, 95% CI: 1.11\u20131.29), with 24.7% of the effect mediated by depression or anxiety. The 14-year cumulative incidence of IBS was 3.1% (95% CI: 2.9\u20133.4) in the lonely group versus 2.1% (95% CI: 2.1\u20132.1) in the non-lonely group (PAF\u2009=\u20092.1%). Compared with non-lonely individuals (95.2%), lonely individuals (4.8%) showed a 46.0% increased IBS risk (HR\u2009=\u20091.46, 95% CI: 1.34\u20131.59), with 26.5% of the effect mediated by depression or anxiety. In addition, one increment in social isolation score (HR\u2009=\u20091.08, 95% CI: 1.04\u20131.11) and loneliness score (HR\u2009=\u20091.27, 95% CI: 1.23\u20131.32) were associated with 8.0% and 27.0% higher IBS risk, respectively. Particularly, most isolated and lonely individuals exhibited a 60.0% greater IBS risk versus their non-lonely and least isolated counterparts (HR\u2009=\u20091.60, 95% CI: 1.35\u20131.89).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Both social isolation and loneliness are associated with increased IBS risk, partially mediated by depression or anxiety.
