Abstract

Obesity is implicated in the development of multiple sclerosis (MS), but its effect on disability is less well-established. This study examined the effects of various obesity measures on MS severity in 12,584 MS cases, using Mendelian randomization to mitigate confounding. Results showed a significant association between higher genetically-determined body mass index (N = 806,834) and increased MS severity (P = 0.02). This finding was supported by additional measures of general obesity but not adiposity distribution. The convergence of this genetic evidence with prior observational studies strengthens the association between obesity and adverse long-term disability in MS, suggesting weight management as a potential therapeutic strategy.

肥胖与多发性硬化症的严重程度：孟德尔随机研究

肥胖与多发性硬化症（MS）的发病有关，但肥胖对残疾的影响尚未得到充分证实。本研究采用孟德尔随机化方法减轻混杂因素，对 12,584 例多发性硬化症病例中各种肥胖指标对多发性硬化症严重程度的影响进行了研究。结果显示，由基因决定的体重指数越高（N = 806,834），多发性硬化症的严重程度就越高（P = 0.02）。这一发现还得到了其他一般肥胖测量指标的支持，但没有得到脂肪分布测量指标的支持。这一遗传学证据与之前的观察性研究相吻合，加强了肥胖与多发性硬化症长期残疾之间的联系，表明体重管理是一种潜在的治疗策略。ann neurol 2024.

期刊介绍： Annals of Neurology publishes original articles with potential for high impact in understanding the pathogenesis, clinical and laboratory features, diagnosis, treatment, outcomes and science underlying diseases of the human nervous system. Articles should ideally be of broad interest to the academic neurological community rather than solely to subspecialists in a particular field. Studies involving experimental model system, including those in cell and organ cultures and animals, of direct translational relevance to the understanding of neurological disease are also encouraged.
