Abstract：
UNASSIGNED: This study aimed to assess the possible association of adherence to the Mediterranean diet (MD) with muscle strength and body composition.
UNASSIGNED: The cross-sectional study evaluated 112 postmenopausal women (aged 41-71 years). Fasting blood samples were obtained for biochemical/hormonal assessment. The Mediterranean Dietary Score (MedDietScore) was calculated and used to stratify adherence by tertiles (low [T1], moderate [T2] or high [T3]). Handgrip strength (HGS) was measured by dynamometry and body composition with dual-X-ray absorptiometry.
UNASSIGNED: Women with low-moderate MedDietScore (T1/T2) had lower HGS values than those with higher scores (19.5 ± 4.9 kg vs. 21.9 ± 3.9 kg, p = 0.023). A linear stepwise increase of HGS values per MedDietScore tertile was found (T1 vs. T2 vs. T3: 18.4 ± 4.4 kg vs. 20.6 ± 5.2 kg vs. 21.9 ± 3.9 kg, ANOVA p-value for linear trend = 0.009, ANCOVA p-value = 0.026). Multivariable models confirmed that HGS values were independently associated with the MedDietScore (β-coefficient = 0.266, p = 0.010). Lean mass values were associated with the MedDietScore (β-coefficient = 0.205, p = 0.040). All models were adjusted for age and cardiometabolic risk factors.
UNASSIGNED: The data suggest that the higher the adherence to the MD, the better the muscle strength and lean mass in postmenopausal women. Prospective studies are required to evaluate the significance of these observations in cardiovascular prevention strategies at midlife.

摘要：
■本研究旨在评估坚持地中海饮食（MD）与肌肉力量和身体成分的可能关联。
■横断面研究评估了112名绝经后妇女（年龄41-71岁）。获得空腹血液样品用于生化/激素评估。计算地中海饮食评分（MedDietScore），并将其用于按三元组（低[T1]，中等[T2]或高[T3])。握力（HGS）通过测力法和双X射线吸收法测量身体组成。
■低-中度MedDietScore（T1/T2）的女性HGS值低于得分较高的女性（19.5±4.9kgvs.21.9±3.9kg,p=0.023)。发现每个MedDietScore三分位数的HGS值呈线性逐步增加(T1与T2vs.T3：18.4±4.4kgvs.20.6±5.2kgvs.21.9±3.9kg,线性趋势的ANOVAp值=0.009，ANCOVAp值=0.026）。多变量模型证实HGS值与MedDietScore独立相关（β系数=0.266，p=0.010）。瘦体重值与MedDietScore相关（β系数=0.205，p=0.040）。所有模型均根据年龄和心脏代谢危险因素进行调整。
■数据表明，对MD的依从性越高，绝经后妇女的肌肉力量和瘦体重越好。需要前瞻性研究来评估这些观察结果在中年心血管预防策略中的重要性。
