BACKGROUND
A single nutrient or dietary pattern has been associated with physical performance. However, little is still known about the association of overall dietary quality with physical performance. This study aimed to investigate the link between the recommended food score (RFS), defined as an indicator of overall diet quality, and physical performance among the Korean elderly aged over 65 years.
METHODS
The study subjects consisted of 622 participants (294 men and 328 women) aged over 65 years from the 2014-2015 National Fitness Award project.
RESULTS
The mean value of RFS was higher in elderly women (30.7 ± 7.6) than elderly men (29.5 ± 8.8), but the difference was only marginally significant (P = 0.065). In elderly women, multiple regression linear models, adjusted for potential confounders, showed that RFS was positively related to absolute hand grip strength (kg) (ß = 0.066, 95% CI = 0.010 to 0.122) and relative hand grip strength (%) (ß =0.109, 95% CI = 0.016 to 0.201); other physical performance indicators did not show any association with RFS. In elderly men, none of the physical performance indexes were associated with RFS.
CONCLUSIONS
These results suggest that a better overall diet quality may be associated with improved grip strength among elderly women in Korea.
背景
单一营养素或饮食模式与身体表现有关。然而，人们对整体饮食质量与身体表现之间的关联仍知之甚少。本研究旨在调查推荐食品评分（RFS）与韩国 65 岁以上老年人身体表现之间的联系。
方法
研究对象为 2014-2015 年国家健身奖项目中 622 名年龄在 65 岁以上的参与者（294 名男性和 328 名女性）。
结果
女性老年人（30.7±7.6）的 RFS 平均值高于男性老年人（29.5±8.8），但差异仅具有边缘统计学意义（P=0.065）。在女性老年人中，经潜在混杂因素调整的多元回归线性模型显示，RFS 与绝对握力（kg）（β=0.066，95%CI=0.010 至 0.122）和相对握力（%）（β=0.109，95%CI=0.016 至 0.201）呈正相关；其他身体表现指标与 RFS 均无关联。在男性老年人中，RFS 与任何身体表现指标均无关联。
结论
这些结果表明，在韩国，更好的整体饮食质量可能与女性老年人握力的提高有关。
