Abstract

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 (pr_s = –.13, p = .36), lean mass (pr_s = .11, p = .40), bone mineral content (pr_s = –.03, p = .80), or bone mineral density (pr_s = –.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.

久坐行为与多发性硬化症患者的身体成分有关吗？

背景：迄今为止，有关多发性硬化症（MS）患者久坐行为与基于体重指数的体重状况之间关系的证据尚不明确，结果相互矛盾可能与测量久坐行为和身体成分的方法有关：本研究探讨了基于设备的久坐时间与通过双能 X 射线吸收测量法（DXA）得出的多发性硬化症患者身体成分结果之间的关系，并将年龄、性别、残疾状况和体力活动作为多发性硬化症患者这两种结果的协变量进行了控制：根据身体质量指数类别招募多发性硬化症患者，以获得各种身体成分评分。参与者（n = 62）完成了 DXA 扫描，并在 7 天内佩戴了腰带式加速度计：结果：久坐时间与脂肪量百分比（prs = -.13，p = .36）、瘦肉量（prs = .11，p = .40）、骨矿物质含量（prs = -.03，p = .80）或骨矿物质密度（prs = -.21，p = .11）无关：结论：在我们的多发性硬化症患者样本中，久坐所花费的时间与身体成分结果的相关性并不显著。这些结果支持考虑久坐行为的其他结果以及久坐行为之外的其他身体成分预测因素。

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.
