衰老改变生物过程，导致身体脂肪重新分配，瘦肌肉质量损失，肌肉力量下降，称为肌肉减少症。营养是肌少症发生的一个重要的可改变的危险因素。粮食不安全指的是获得足够食物以维持积极健康生活的机会有限或不确定，这种情况在老年人中普遍存在。本研究的目的是检查老年人食物不安全与可能的肌肉减少症之间的关系。我们调查了2011-2014年全国健康与营养调查（NHANES）中3,632名≥60岁的成年人。在我们的分析中，粮食不安全是使用粮食安全调查模块（FSSM）确定的。主要结局是基于肌少症定义和结局联盟（SDOC）的定义。次要结果基于其他三种不同的握力临界值，因为在该领域对肌肉减少症的最佳定义存在争议。与修订后的关于肌少症定义和诊断的欧洲共识（EWGSOP2）建议一致，我们在本文中使用了术语“可能的肌少症”，因为定义仅基于肌肉力量，不包括对肌肉质量的评估。采用食品安全的标准四类定义进行敏感性分析。我们使用逻辑回归来检验食品不安全和肌肉减少症之间的关系。根据肌肉减少症定义和结局协会的定义，24.7%的患者被归类为可能的肌肉减少症（握力低）；5.5%的人有食物不安全，食物不安全与可能的肌肉减少症相关（OR 1.51, 95%CI 1.03-2.22）。使用其他三种可能的肌肉减少症定义，食品不安全与可能的肌肉减少症显著相关，使用美国国立卫生研究院基金会仅使用握力定义（OR 1.71, 95%CI 1.08-2.71），但使用握力/BMI （OR 1.16, 95%CI 0.76-1.78）或握力/体重（OR 1.14, 95%CI 0.85-1.54）相关定义，食品不安全与可能的肌肉减少症不相关。在这项具有全国代表性的队列研究中，与完全粮食安全的个体相比，被归类为粮食不安全的个体更有可能患有肌肉减少症（握力低）。未来的研究应该检查粮食不安全干预是否可以减少可能的肌肉减少症和相关的不良后果。
Aging alters biological processes resulting in body fat redistribution, loss of lean muscle mass, and reduced muscle strength, termed sarcopenia. Nutrition is an important modifiable risk factor in the development of sarcopenia. Food insecurity refers to limited or uncertain access to enough food for an active, healthy life, and is prevalent among older adults. The objective of this study was to examine the relationship between food insecurity and probable sarcopenia in older adults. We examined 3,632 adults ≥60 years old from the 2011–2014 National Health and Nutrition Examination Surveys (NHANES). For our analysis food insecurity was identified using the Food Security Survey Module (FSSM). The primary outcome was based on the Sarcopenia Definitions and Outcomes consortium (SDOC) definition. Secondary outcomes were based on three other different grip strength cut-offs as there is debate within the field as to the optimal definition of sarcopenia. Consistent with the revised European consensus on the definition and diagnosis of Sarcopenia (EWGSOP2) recommendations, we used the term probable sarcopenia throughout this text as definitions were based on muscle strength alone and did not include an evaluation of muscle quality. Sensitivity analyses were performed using the standard four category definition of food security. We used logistic regression to examine the association between food insecurity and sarcopenia. Using the Sarcopenia Definitions and Outcomes Consortium definition, 24.7% were classified as having probable sarcopenia (low grip strength); 5.5% had food insecurity and food insecurity was associated with probable sarcopenia (OR 1.51, 95%CI 1.03–2.22). Using three other definitions of probable sarcopenia, food insecurity was significantly associated with probable sarcopenia using the Foundation for the National Institute of Health definition using grip strength alone (OR 1.71, 95%CI 1.08–2.71), but food insecurity was not associated with food insecurity using definitions related to grip strength/BMI (OR 1.16, 95%CI 0.76–1.78) or grip strength/weight (OR 1.14, 95%CI 0.85–1.54). In this nationally representative cohort study, individuals classified as having food insecurity were more likely to have probable sarcopenia (low grip strength) compared to those with full food security. Future studies should examine whether food insecurity interventions may reduce probable sarcopenia and associated adverse outcomes.
