背景/目的：坚持地中海饮食(MD)，富含水果、蔬菜和单不饱和脂肪，与较低的体重指数有关。与测量的体脂，包括区域性肥胖症的关系，以前还没有被调查过。我们研究了交替地中海饮食评分(AMED)、人体测量和双能X射线吸收法(DXA)测量的肥胖之间的关系。每名女性的AMED(范围0-9)是从1-2个月经周期内最多8次24小时饮食召回计算得出的(97%有7次召回)。在调整了年龄、种族、教育程度、体力活动和能量摄入后，采用多元线性回归方法确定AMED及其特定成分是否与总体和区域性肥胖症有关。AMED为4.2(1.7)，体脂百分比为29.5(6.0)%。除了腰臀比外，AMED与所有检查的肥胖指标之间存在显著的负相关。在DXA测量中，AMED增加1个单位与躯干与腿部脂肪比(T/L)降低0.06(95%可信区间：-0.09，-0.02)相关，T/DXA是衡量上下半身脂肪的指标。在对T/L进行的分析中，T/L随着豆类消费量的增加而降低(Beta=-0.280，95%CI：-0.550，-0.010)，但随着红肉和加工肉类消费量的增加(Beta=0.060，95%CI：0.002，0.117)，T/L降低。结论：坚持服用AMD与总体和局部肥胖率降低有关，这进一步证明了MD对健康的益处。《欧洲临床营养学杂志》(2013年)67289-294；doi：10.1038/ejcn.2013.4；2013年2月6日在线发布
BACKGROUND/OBJECTIVES: Adherence to the Mediterranean diet (MD), high in fruits, vegetables and monounsaturated fats, has been associated with lower body mass index. Associations with measured body fat, including regional adiposity, have not been previously investigated. We examined the associations between the alternate Mediterranean diet score (aMED), anthropometry and measured adiposity by dual-energy x-ray absorptiometry (DXA).SUBJECTS/METHODS: This study included 248 healthy females, aged 18-44 years from the BioCycle Study. Each woman's aMED (range 0-9) was calculated from up to eight 24-h dietary recalls over 1-2 menstrual cycles (>97% had >= 7 recalls). Multiple linear regression was used to determine whether aMED and its specific components were associated with total and regional adiposity after adjusting for age, race, education, physical activity and energy intake.RESULTS: Participants had an average (s.d.) aMED of 4.2 (1.7) and percent body fat of 29.5 (6.0)%. Significant inverse associations were found between aMED and all the examined adiposity measures except waist-to-hip ratio. Among the DXA measures, a 1-unit increment in aMED was associated with a 0.06 (95% confidence interval (CI): -0.09, -0.02) lower trunk-to-leg fat ratio (T/L), a measure of upper to lower body fat. In an analysis examining T/L as an outcome with the separate components of the aMED, T/L was lower with increased legume consumption (beta = -0.280, 95% CI: -0.550, -0.010) but was higher with increased consumption of red and processed meat (beta = 0.060, 95% CI: 0.002, 0.117).CONCLUSIONS: Adherence to the aMED was associated with lower total and regional adiposity, adding to the mounting evidence of the health benefits of the MD.
