Is sedentary behavior associated with body composition in multiple sclerosis?
Background
To date, the evidence regarding the relationship between sedentary behavior and weight status based on body mass index in multiple sclerosis (MS) has not been definitive, and the conflicting results may be associated with the approaches for measurement of sedentary behavior and body composition.
Objective
The current study examined the relationship between device-based sedentary time and body composition outcomes derived from dual-energy x-ray absorptiometry (DXA) in persons with MS, controlling for age, sex, disability status, and physical activity as covariates of both outcomes in MS.
Methods
Persons with MS were recruited based on body mass index categories for a full range of body composition scores. Participants (n = 62) completed a DXA scan and wore an accelerometer on a belt for a 7-day period.
Results
Sedentary time was not associated with percent fat mass (prs = –.13, p = .36), lean mass (prs = .11, p = .40), bone mineral content (prs = –.03, p = .80), or bone mineral density (prs = –.21, p = .11).
Conclusions
Time spent in sedentary behavior was not significant correlated with body composition outcomes in our sample of persons with MS. These results support the consideration of other outcomes of sedentary behavior as well as other predictors of body composition over-and-beyond sedentary behavior.
期刊介绍：
Multiple Sclerosis is an area of ever expanding research and escalating publications. Multiple Sclerosis and Related Disorders is a wide ranging international journal supported by key researchers from all neuroscience domains that focus on MS and associated disease of the central nervous system. The primary aim of this new journal is the rapid publication of high quality original research in the field. Important secondary aims will be timely updates and editorials on important scientific and clinical care advances, controversies in the field, and invited opinion articles from current thought leaders on topical issues. One section of the journal will focus on teaching, written to enhance the practice of community and academic neurologists involved in the care of MS patients. Summaries of key articles written for a lay audience will be provided as an on-line resource.
A team of four chief editors is supported by leading section editors who will commission and appraise original and review articles concerning: clinical neurology, neuroimaging, neuropathology, neuroepidemiology, therapeutics, genetics / transcriptomics, experimental models, neuroimmunology, biomarkers, neuropsychology, neurorehabilitation, measurement scales, teaching, neuroethics and lay communication.
