背景资料：最近的研究表明，乳制品消费和相关的营养素可能对代谢综合征（MetS）的某些成分具有保护作用。目的：我们研究了各种乳制品及其相关营养素的消费与肥胖、向心性肥胖和代谢综合征之间的关联，并试图通过全国数据解释乳制品消费在代谢结果方面的一些种族差异。设计：美国成年人肥胖、向心性肥胖和代谢综合征的全国代表性指标是根据1999-2004年国家健康和营养调查数据构建的，包括直接人体测量评估、血压和实验室检查。样本量范围从代谢综合征的4519到肥胖的14618。饮食（使用24小时召回评估）和代谢和其他结果之间的关联进行了测试，使用多变量线性和逻辑模型和结构方程models.Results：我们发现摄入全脂牛奶，酸奶，钙，镁和代谢紊乱之间的显着负相关。每天多吃一份酸奶和100 mg镁对MetS的优势比分别为0.40（95%CI：0.18，0.89）和0.83（95%CI：0.72，0.96）。而奶酪、低脂牛奶和磷的摄入量则相反。使用结构方程模型，种族差异在一些代谢综合征的结果，如体重指数和收缩压，部分原因是在乳制品相关的nutritions.Conclusions的变化：各种乳制品可能有不同的协会与代谢紊乱，包括肥胖。乳制品消费的种族差异可能部分解释了美国人群中代谢紊乱的种族差异。
Background: Recent studies suggest dairy consumption and associated nutrients may be protective against some of the components of the metabolic syndrome (MetS).Objectives: We examined the association between consumption of a variety of dairy products and their related nutrients with obesity, central obesity, and MetS, and attempted to explain some of the ethnic differences in metabolic outcomes through dairy consumption using national data.Design: Nationally representative indicators of obesity, central obesity, and MetS among US adults were constructed from National Health and Nutrition Examination Survey 1999-2004 data, including direct anthropometric assessments, blood pressure, and laboratory tests. Sample sizes ranged from 4519 for MetS to 14 618 for obesity. Associations between diet (assessed using 24-h recalls) and metabolic and other outcomes were tested using multivariate linear and logistic models and structural equation models.Results: We found a significant inverse association between intake of whole milk, yogurt, calcium, and magnesium and metabolic disorders. Odds ratios for one more daily serving of yogurt and 100 mg Mg for MetS were 0.40 (95% CI: 0.18,0.89) and 0.83 (95% CI: 0.72, 0.96), respectively. The opposite was found for intakes of cheese, low-fat milk, and phosphorus. Using structural equation models, ethnic differences in some MetS outcomes, such as body mass index and systolic blood pressure, were partly explained by variations in dairy-related nutrients.Conclusions: Various dairy products may have differential associations with metabolic disorders, including obesity. Ethnic differences in dairy consumption may explain in part the ethnic disparities in metabolic disorders in the US population.
