| Sumario: | Objective: The present study presents long-term results of stress-related outcomes of a prospective RCT that evaluated effects of a ten-week comprehensive lifestyle-modification program (LSM) in patients with inactive ulcerative colitis (UC). In addition, exploratory results of a sub-study applying a laboratory stress protocol (Trier Social Stress Test; TSST) conducted within the RCT are reported. Methods: Ninety-seven patients with inactive UC were randomized to LSM (<i>n</i> = 47; 50.28 ± 11.90 years; 72.3% female) or self-care (<i>n</i> = 50; 45.54 ± 12.49 years; 70% female). Patients’ perceived stress, anxiety, flourishing and depression were assessed at week 0, 12, 24 and 48. After the respective intervention, 16 female patients (LSM: <i>n</i> = 8; 44.6 ± 14.3 years; Self-care: <i>n</i> = 8; 49.25 ± 4.30 years) additionally underwent the TSST. State anxiety, blood pressure, pulse, complete blood counts, adrenocorticotropic hormone (ACTH), cortisol, adrenalin and noradrenalin were measured at <i>baseline</i> (−15 min), <i>stress</i> (+10 min), <i>recovery1</i> (+20 min) and <i>recovery2</i> (+55 min). Statistical significance was set at <i>p</i> < 0.05; for the exploratory sub-study using the TSST, <i>p</i>-values < 0.10 were considered significant. Results: Patients’ perceived stress declined significantly after the LSM (<i>p</i> < 0.001) compared with control. This lasted until week 24 (<i>p</i> = 0.023) but did not persist until week 48 (<i>p</i> = 0.060). After 48 weeks, patients’ flourishing was significantly increased compared with control (<i>p</i> = 0.006). In response to the TSST, significant group differences were evident for pulse (<i>p</i> = 0.015), adrenaline (<i>p</i> = 0.037) and anxiety (<i>p</i> = 0.066). After 55 min, group differences were found for ACTH (<i>p</i> = 0.067) and systolic blood pressure (<i>p</i> = 0.050). Conclusions: LSM has a medium-term positive effect on perceived stress. First indications show that it is promising to investigate these effects further under laboratory conditions. It is also desirable to find out how the effects of LSM can be maintained in the long term. |
