several studies have found nutrients, including antioxidants, to be associated with sarcopenia. However, whether specific foods, such as vegetables and fruits, are associated with sarcopenia has not been studied.
to examine the association of the frequency of vegetables and fruits consumption with sarcopenia in older people.
this study used cross-sectional data from the Fourth Korea National Health and Nutrition Examination Survey in 2008-09. Subjects were community-dwelling 823 men and 1,089 women aged ≥65 years. Frequency of food group consumption was obtained by using the food frequency questionnaire. Body composition was measured with the dual-energy X-ray absorptiometry and sarcopenia was defined as appendicular lean mass adjusted for height and fat mass. Logistic regression was used to assess the association of the frequency of food group consumption with sarcopenia, controlling for sociodemographics and health-related variables.
dietary intake of vegetables, fruits and both vegetables and fruits was associated with a significantly reduced risk of sarcopenia after controlling for covariates in men (P = 0.026 for trend, P = 0.012 for trend, P = 0.003 for trend, respectively). Men in the highest quintile, compared with those in the lowest quintile, of vegetables [odds ratio (OR) = 0.48; 95% confidence interval (CI): 0.24-0.95], fruits (OR = 0.30; 95% CI: 0.13-0.70) and vegetables and fruits consumption (OR = 0.32; 95% CI: 0.16-0.67) demonstrated a lower risk of sarcopenia. In women, high consumption of fruits demonstrated a lower risk of sarcopenia (OR = 0.39; 95% CI: 0.18-0.83).
frequent vegetables and fruits consumption was inversely associated with sarcopenia in older adults.
多项研究发现包括抗氧化剂在内的营养素与肌肉减少症有关。然而，诸如蔬菜和水果等特定食物是否与肌肉减少症有关尚未得到研究。
探讨老年人蔬菜和水果的食用频率与肌肉减少症之间的关联。
本研究使用了2008 - 2009年第四次韩国国家健康与营养检查调查的横断面数据。研究对象为居住在社区的823名男性和1089名年龄≥65岁的女性。食物组食用频率通过食物频率问卷获得。采用双能X线吸收法测量身体成分，肌肉减少症定义为根据身高和脂肪量调整后的四肢瘦体重。使用逻辑回归评估食物组食用频率与肌肉减少症之间的关联，并对社会人口统计学和健康相关变量进行控制。
在男性中，在控制协变量后，蔬菜、水果以及蔬菜和水果的饮食摄入量与肌肉减少症风险显著降低相关（趋势P值分别为0.026、0.012、图003）。蔬菜食用量最高五分位数的男性与最低五分位数的男性相比，肌肉减少症风险较低[比值比（OR） = 0.48；95%置信区间（CI）：0.24 - 0.95]，水果（OR = 0.30；95% CI：0.13 - 0.70）以及蔬菜和水果食用量（OR = 0.32；95% CI：0.16 - 0.67）。在女性中，高水果摄入量与较低的肌肉减少症风险相关（OR = 0.39；95% CI：0.18 - 0.83）。
老年人经常食用蔬菜和水果与肌肉减少症呈负相关。
