The aim of this study was to examine the impact of IBD on patient-reported outcomes and costs among Japanese adults (≥18 years). Patients and methods: This retrospective cross-sectional study used data from the 2012–2014 Japan National Health and Wellness Survey (N=83,505). HRQoL (SF-36v2), work productivity and activity impairment (work productivity and activity impairment-General Health Questionnaire), HRU, and annual costs were compared between respondents with IBD (n=441) and non-IBD controls (n=82,944), and within IBD subtypes (Crohn’s disease [CD] and ulcerative colitis [UC]) using chi-square and ANOVA tests. Results: Mental Component Summary (MCS), Physical Component Summary (PCS), and health state utility (Short-Form-6 Dimensions [SF-6D]) scores were significantly lower in IBD respondents than in controls (differences of 2.2 points, 2.6 points, and 0.041 points, respectively; all P
