RESUMO
BACKGROUND: Multiple sclerosis is a demyelinating autoimmune disease, presenting with heterogenous symptoms that impact daily living. Undertaking stress-reducing activities may reduce symptoms including depression and fatigue, and enhance mastery, the sense of control of one's life. We assessed cross-sectional associations of undertaking stress-reducing activities or meditation on depression, fatigue, and mastery, and 5-year prospective relationships between meditation and these outcomes. METHODS: Data were extracted from the longitudinal Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) study. Stress-reducing activities were categorised to relaxation, physical, mind-body, and spiritual. Meditation was analysed as a dichotomous term, and for duration and frequency of practice. Depression, fatigue, and mastery were assessed by Patient's Health Questionnaire-9, Fatigue Severity Scale, and Pearlin Mastery Scale, respectively. Associations with depression, fatigue and mastery were assessed by log-binomial regression. Models were adjusted for age, sex, symptoms due to relapse, socioeconomic status, employment status, and antidepressant and anti-fatigue medication use, as appropriate. RESULTS: Cross-sectionally, physical and relaxation activities were associated with 40% and 33% lower frequencies of depression, respectively. Physical activities were additionally associated with 19% lower frequency of fatigue. Meditation was associated with 30% lower frequency of depression and 17% higher mastery. Prospectively, meditation was associated with 28% decreased depression, and 48% reduction of developing depression at 5-year follow-up. CONCLUSION: Potential benefits of undertaking stress-reducing activities, or meditation, on depression, fatigue, and mastery are promising and should be further assessed prospectively. Meditation practice should be encouraged as a safe and inexpensive intervention for prevention of depression.
