Researches have suggested Mediterranean diet might lower the risk of chronic diseases, but data on skeletal muscle mass (SMM) are limited. This community-based cross-sectional study examined the association between the alternate Mediterranean diet score (aMDS) and SMM in 2230 females and 1059 males aged 40-75 years in Guangzhou, China. General information and habitual dietary information were assessed in face-to-face interviews conducted during 2008-2010 and 3 years later. The aMDS was calculated by summing the dichotomous points for the items of higher intakes of whole grain, vegetables, fruits, legumes, nuts, fish and ratio of MUFA:SFA, lower red meat and moderate ethanol consumption. The SMM of the whole body, limbs, arms and legs were measured using dual-energy X-ray absorptiometry during 2011-2013. After adjusting for potential covariates, higher aMDS was positively associated with skeletal muscle mass index (SMI, SMM/height2, kg/m2) at all of the studied sites in males (all P trend<0·05). The multiple covariate-adjusted SMI means were 2·70 % (whole body), 2·65 % (limbs), 2·50 % (arms) and 2·70 % (legs) higher in the high (v. low) category aMDS in males (all P<0·05). In females, the corresponding values were 1·35 % (P trend=0·03), 1·05, 0·52 and 1·20 %, (P trend>0·05). Age-stratified analyses showed that the favourable associations tended to be more pronounced in the younger subjects aged less than the medians of 59·2 and 62·2 years in females and males (P interaction>0·10). In conclusion, the aMDS shows protective associations with SMM in Chinese adults, particularly in male and younger subjects.
研究表明，地中海饮食可能会降低患慢性病的风险，但关于骨骼肌质量（SMM）的数据有限。这项基于社区的横断面研究调查了中国广州2230名40至75岁女性和1059名男性中，替代地中海饮食评分（aMDS）与SMM之间的关联。在2008 - 2010年及3年后进行的面对面访谈中评估了一般信息和习惯性饮食信息。aMDS通过对全谷物、蔬菜、水果、豆类、坚果、鱼类摄入量较高以及MUFA:SFA比例较高、红肉摄入量较低和适度饮酒的项目的二分点进行求和来计算。在2011 - 2013年期间使用双能X线吸收法测量全身、四肢、手臂和腿部的SMM。在调整潜在协变量后，较高的aMDS与男性所有研究部位的骨骼肌质量指数（SMI，SMM/身高²，kg/m²）呈正相关（所有P趋势<0·05）。在男性中，高（对比低）类别aMDS的多协变量调整后的SMI均值在全身高2·70%，四肢高2·65%，手臂高2·50%，腿部高2·70%（所有P<0·05）。在女性中，相应的值分别为1·35%（P趋势 = 0·03），1·05%，0·52%和1·20%（P趋势>0·05）。年龄分层分析表明，在女性和男性年龄小于中位数59·2岁和62·2岁的较年轻受试者中，这种有利关联往往更为明显（P交互作用>0·10）。总之，aMDS与中国成年人的SMM呈保护性关联，尤其是在男性和较年轻的受试者中。
