Fruit and vegetable consumption may protect against sarcopenia but there are no studies on this topic from low- and middle-income countries (LMICs). Thus, we assessed this association among older adults from six LMICs. Community-based cross-sectional data of the Study on Global Aging and Adult Health were analyzed. Sarcopenia was defined as the presence of low skeletal muscle mass based on indirect population formula, and either slow gait or low handgrip strength. Quintiles of vegetable and fruit consumption were created based on the number of servings consumed on a typical day. Multivariable logistic regression analysis was conducted. The sample consisted of 14,585 individuals aged ≥65 years (mean (SD) age 72.6 (11.4) years; 55% females). Adjusted analyses showed that overall, compared to the lowest quintile (Q1), the highest quintile (Q5) of fruit consumption was associated with a 40% lower odds for sarcopenia (OR = 0.60; 95% CI = 0.42-0.84) but this association was largely driven by the strong association among females (e.g., Q5 vs. Q1 OR = 0.42; 95% CI = 0.24-0.73), with no significant associations found among males. Vegetable consumption was not significantly associated with sarcopenia. Future studies of longitudinal design may shed light on whether increasing fruit consumption among older females in LMICs may reduce risk for sarcopenia.
水果和蔬菜的摄入可能有助于预防肌肉减少症,但在中低收入国家(LMICs)尚未对此进行研究。因此,我们评估了来自六个 LMICs 的老年人的这种关联。对全球老龄化和成人健康研究的基于社区的横断面数据进行了分析。根据间接人群公式,将低骨骼肌量、缓慢的步态或低握力定义为肌肉减少症。根据每天摄入的份数,创建了蔬菜和水果摄入量的五分位数。进行了多变量逻辑回归分析。样本包括 14585 名年龄≥65 岁的个体(平均(SD)年龄 72.6(11.4)岁;55%为女性)。调整后的分析表明,与最低五分位(Q1)相比,总体而言,水果摄入量最高的五分位(Q5)与肌肉减少症的几率降低 40%相关(OR=0.60;95%CI=0.42-0.84),但这种关联主要是由女性的强关联驱动的(例如,Q5 与 Q1 的 OR=0.42;95%CI=0.24-0.73),而男性中没有发现显著关联。蔬菜摄入量与肌肉减少症无显著关联。未来的纵向研究可能会揭示,在 LMICs 中增加老年女性的水果摄入量是否可能降低肌肉减少症的风险。
