The HOLISM Study
|Professor George Jelinekemail@example.com||View page|
A growing literature on the effects of lifestyle on the progression of multiple sclerosis (MS) highlights the potential benefit of diet, exercise, sun exposure and/or vitamin D, Omega-3 supplementation, and stress reduction. In the HOLISM study (Health Outcomes and Lifestyle In a Sample of people with Multiple Sclerosis) we aimed to recruit participants from online social media promoting lifestyle-based interventions in MS and examine in detail these factors, and determine their relationship to quality of life, relapse rate, physical function and disability. Around 2,500 participants who provided consent responded to an online questionnaire, providing demographic and disease-specific data as well as details of diet, exercise, sun exposure, vitamin D level and supplements, stress reduction techniques, medication use, and disability, using validated survey instruments, modified where necessary. Participants are followed at 2.5 year intervals in a longitudinal cohort study. Regression analyses have examined the predictors of functional status, depression risk, fatigue, sexual function, pain, cognitive function and quality of life from the demographic, lifestyle and medication factors, and their relative contributions. These data will assist in determining the association between lifestyle factors and health outcomes in people with MS, globally. They will also help to inform future research, and advise people with MS of the potential contribution of lifestyle to their health-related quality of life and physical disability. There have been 15 publications from the HOLISM Study to date.
