BACKGROUND/OBJECTIVES: The Mediterranean diet (MEDDIET) has been shown to be related to longevity. This study aimed to determine the association between adherence to MEDDIET and physical function of older adults in the United-States and Israel.
Data from the US National Health and Nutrition Survey (NHANES) 1999-2002 and from the Israeli National Health and Nutrition Survey (MABAT ZAHAV) 2005-2006 were used. Participants with nutritional and functional data were included. Adherence to the MEDDIET was assessed by a 9-unit score (MDS).
Among 2791 NHANES and 1786 MABAT ZAHAV participants, mean age=71.2 y and 74.9 y, 20% and 27% had low MDS (0-2), 66% and 62% had a medium score (3-5), and 14% and 11% had a high score (6-9), respectively. Higher MDS was associated with higher education and better lifestyle behaviors. Cognitive and physical functions were significantly better in NHANES and MABAT ZAHAV among the highest MDS. In NHANES, MDS (high vs. low) was associated with faster walking speed after adjusting for confounders in a logistic regression model [Odds Ratio (OR)=0.71, P=0.034, Cl 95% 0.511-0.974]. When cognitive function was added, the association was attenuated (OR=0.75, P=0.093, Cl 95% 0.540-1.049). In MABAT ZAHAV, in a logistic regression model adjusted among other to cognitive function, MDS (high vs. low) was associated with fewer disabilities (OR=0.51, P=0.029, Cl 95% 0.276-0.934).
Adherence to the MEDDIET is associated with better health characteristics and better functioning. Further cohort and intervention studies may shed light on temporal and causal relationships between MEDDIET and these parameters.
背景/目的：地中海饮食已被证明与长寿有关。本研究旨在确定美国和以色列老年人坚持地中海饮食与身体功能之间的关联。
使用了1999 - 2002年美国国家健康与营养调查（NHANES）以及2005 - 2006年以色列国家健康与营养调查（MABAT ZAHAV）的数据。纳入具有营养和功能数据的参与者。通过9分制评分（MDS）评估对地中海饮食的依从性。
在2791名NHANES参与者和1786名MABAT ZAHAV参与者中，平均年龄分别为71.2岁和74.9岁，20%和27%的人MDS得分低（0 - 2分），66%和62%的人得分为中等（3 - 5分），14%和11%的人得分为高（6 - 9分）。较高的MDS与较高的教育水平和更好的生活方式行为相关。在NHANES和MABAT ZAHAV中，MDS得分最高的人群认知和身体功能明显更好。在NHANES中，在逻辑回归模型中调整混杂因素后，MDS（高分组与低分组）与更快的步行速度相关[优势比（OR）=0.71，P = 0.034，95%置信区间0.511 - 0.974]。当加入认知功能因素后，这种关联减弱（OR = 0.75，P = 0.093，95%置信区间0.540 - 1.049）。在MABAT ZAHAV中，在调整了包括认知功能等因素的逻辑回归模型中，MDS（高分组与低分组）与较少的残疾相关（OR = 0.51，P = 0.029，95%置信区间0.276 - 0.934）。
坚持地中海饮食与更好的健康特征和功能相关。进一步的队列研究和干预研究可能会揭示地中海饮食与这些参数之间的时间和因果关系。
