摘要

Purpose

Nutrition and exercise interventions are increasingly considered as adjunct strategies in ulcerative colitis (UC) management; however, evidence from short-term pragmatic programs focusing on patient-centered disease-management outcomes in active disease remains limited. We evaluated the effects of a 4-week lifestyle program on health-related quality of life (HRQoL), nutrition–exercise behaviors, self-management outcomes, and patient-reported symptom activity in adults with active UC.

Methods

In this pre–post study, adults with active disease completed a 4-week program including aerobic exercise (3 days/week, moderate intensity defined as Borg RPE 12–14) and resistance training (2 days/week; 2–3 sets of 8–12 repetitions with progressive overload). Outcomes were assessed at baseline and week 4 using SF-36, the Nutrition–Exercise Behavior Scale (NEBS), the IBD Self-Efficacy Scale (IBD-SES), and a patient-reported symptom activity measure (P-SCCAI). Paired tests were selected according to distributional assumptions; effect sizes were reported as Cohen’s d(z).

Results

Primary outcomes improved significantly (SF-36 Physical Functioning, p = 0.041; NEBS Healthy Nutrition–Exercise Behavior, p < 0.001). Several secondary outcomes also improved significantly, including multiple SF-36 domains and key behavioral/self-management measures, whereas patient-reported symptom activity did not show a significant change (p = 0.145).

Conclusion

A brief, structured nutrition- and exercise-based adjunct program was associated with meaningful improvements in HRQoL and disease-management-related behaviors in adults with active UC. Controlled studies are warranted to confirm effectiveness and clarify impacts on symptom activity.
