Physiological changes that occur after spinal cord injury (SCI) are profound and affect almost every organ system in the human body. Energy balance is significantly altered due to motor paralysis, spasticity or flaccidity, neurogenic sarcopenia, neurogenic osteopenia, sympathetic nervous system disruption, and blunted anabolism. Energy expenditure is markedly reduced, whereas hypothalamic control of appetite and satiety is diminished, resulting in discordant energy intake. Ultimately, neurogenic obesity ensues as the result of a positive energy balance. Even though nutritional guidelines for persons with SCI have been available since 2009, the necessity for body composition assessment and total daily energy expenditure was insufficiently addressed such that most individuals with SCI continued in positive energy balance despite "adherence" to the guidelines. Macronutrients must be carefully assessed to optimize caloric intake, while micronutrient consumption may need to be supplemented in order to meet recommended daily allowances. Such a diet would emphasize foods with low caloric yet high nutrient density. This article reviews current literature regarding nutritional requirements for SCI and provides a straightforward plan for implementing more rigorous dietary interventions meant to address the obesity crisis in this especially vulnerable population.
脊髓损伤 (SCI) 后发生的生理变化是深刻的,几乎影响人体的每一个器官系统。由于运动麻痹、痉挛或弛缓、神经性肌萎缩、神经性骨质疏松症、交感神经系统紊乱和合成代谢减弱,能量平衡显著改变。能量消耗明显减少,而下丘脑对食欲和饱腹感的控制减弱,导致能量摄入不协调。最终,由于能量正平衡,导致神经性肥胖。尽管自 2009 年以来就有针对 SCI 患者的营养指南,但对身体成分评估和每日总能量消耗的必要性的认识不足,导致大多数 SCI 患者尽管“遵循”了指南,但仍处于能量正平衡状态。必须仔细评估宏量营养素以优化热量摄入,而可能需要补充微量营养素以满足每日推荐摄入量。这种饮食将强调低热量但高营养密度的食物。本文综述了有关 SCI 营养需求的最新文献,并提供了一个实施更严格饮食干预的简单计划,旨在解决这一特别脆弱人群的肥胖危机。
