RESUMO
BACKGROUND AND PURPOSE: Healthy lifestyle behaviour modification may improve health outcomes in people with multiple sclerosis (pwMS), but empirical evidence is needed to confirm prior study findings. We developed an online multimodal lifestyle intervention (Multiple Sclerosis Online Course) to examine the impact of lifestyle modification on health outcomes in pwMS via a randomized control trial (RCT). However, the present study specifically analyses baseline data to assess engagement with healthy lifestyles by RCT participants and cross-sectional associations with health outcomes. METHODS: Baseline engagement with six "healthy lifestyle behaviours" of the intervention course (high-quality, plant-based diet; ≥5000 IU/day vitamin D; omega-3 supplementation; ≥30 min physical activity 5 times/week; ≥30 min/week meditation; and nonsmoking) was examined. Associations between individual versus collective behaviours (individual behaviours summated) and health outcomes (quality of life [QoL]/fatigue/disability) were evaluated using multivariate modelling (linear/log-binomial/multinomial). RESULTS: At baseline, 33.7% and 30.0% of participants (n = 857) engaged in one or two healthy behaviours, respectively. In total, engagement with healthy lifestyles by participants was as follows: nonsmoking, 90.7%; omega-3 supplementation, 34.5%; vitamin D supplementation, 29.8%; physical activity, 29.4%; diet, 10.7%; and meditation, 10.5%. Individual behaviours (nonsmoking/physical activity/diet) were independently associated with better health outcomes. Engagement with multiple behaviours, especially diet and physical activity, was associated with better outcomes; engaging with ≥4 behaviours was associated with a 9.0-point higher mental QoL and a 9.5-point higher physical QoL, as well as 23% and 56% lower prevalence of fatigue and moderate disability, respectively. CONCLUSIONS: Baseline engagement with ≥4 healthy behaviours, including diet and physical activity, was associated with better health outcomes.
RESUMO
BACKGROUND: Fatigue and disability are indicators of disease progression experienced by many people with multiple sclerosis (pwMS). Understanding trajectories of these outcomes, and their predictors, may provide insight to potential interventions for MS management. METHODS: Survey data from 839 pwMS from the Health Outcomes and Lifestyle in pwMS study were analysed. Fatigue was defined as mean Fatigue Severity Scale >5, and severe disability as Patient Determined Disease Steps >5. Group-based trajectory modelling was used to identify fatigue and disability trajectories over five-years. Dietary predictors associated with outcome trajectory group membership were assessed using log-binomial regression. Demographic and clinical characteristics were considered in multivariable models. RESULTS: Distinct trajectories for fatigue and disability were identified. For fatigue, 58 % of pwMS were assigned to low-, and 42 % to high-, fatigue trajectory groups. For disability, 85 % of pwMS were assigned to low-, and 15 % to high-, disability groups. Baseline high-quality diet, and omega-3 and vitamin D supplement use, were associated with reduced risk of being in high-fatigue and high-disability trajectories, while meat and dairy consumption were associated with increased risk. CONCLUSIONS: A high-quality diet, avoiding meat and dairy, and omega-3 and vitamin D supplement use, individually predict better fatigue and disability trajectories. Dietary modifications should be considered in MS management.

BACKGROUND: Digital technologies have afforded people living with multiple sclerosis (MS) access to telehealth consultations, diagnostic tools, and monitoring. Although health care professionals remain the most trusted source of information, the internet has emerged as a valuable resource for providing MS-related information, particularly during the COVID-19 pandemic. Notably, people living with MS are increasingly seeking educational content for a range of topics related to the self-management of MS; however, web-based information seeking remains largely underevaluated. To address this gap and ensure that web-based health-related information is accessible and engaging, this study used qualitative methods to analyze the reflections from participants of web-based educational programs for people living with MS. OBJECTIVE: This study aimed to explore the motivations, behaviors, and expectations of web-based health information seeking for people living with MS. METHODS: We conducted semistructured interviews for 38 people living with MS 1 month after they completed the novel MS Online Course, which provided information on modifiable lifestyle-related risk factors for people living with MS. Of the 38 participants, 22 (58%) completed the intervention course and 16 (42%) completed the standard care course. Inductive thematic analysis was used within a qualitative paradigm, and 2 authors coded each interview separately and arrived at themes with consensus. RESULTS: We identified 2 themes: motivation to learn and MS information on the web. The diagnosis of MS was described as a pivotal moment for precipitating web-based information seeking. People living with MS sought lifestyle-related information to facilitate self-management and increase control of their MS. Although social media sites and MS websites were considered useful for providing both support and information, discretion was needed to critically appraise information. Recognizable institutions were frequently accessed because of their trustworthiness. CONCLUSIONS: This study provided novel insights into the motivations of people living with MS for seeking web-based health information. Furthermore, their preferences for the content and format of the web-based information accessed and their experiences and reactions to this information were explored. These findings may guide educators, researchers, and clinicians involved in MS care to optimize the engagement and processing of web-based health information seeking by people living with MS.
