目的：有限的数据表明，与没有综合征的人相比，患有代谢综合征的人的摄入量或循环浓度较低。这项研究的目的是检查镁的饮食摄入量与全国代表性的美国成人样本中的代谢综合征的患病率之间的关联。研究方法和程序：我们使用了7669名参与者的数据> = 20岁的数据> = 20岁。第三个国家健康与营养考试调查（1988年至1994年）。使用国家胆固醇教育计划的标准定义了代谢综合征。镁的摄入量是由单个饮食的24小时召回来确定的：反应：代谢综合征的未经调整的患病率为29.0％（最低镁摄入量的五分之一），27.5％。 25.8％。增加镁摄入量的五分位数为23.9％，21.8％（趋势= 0.002）。多次调整后，分析中所有参与者中第二个五分位数（最高摄入量）的几率比率为0.84 [95％置信区间（CL）：0.58，1.23]，0.76（95％CI：95％CI：： 0.54，1.07），0.62（95％CI：0.407 0.98）。和0.56（95％CI：0.34，0.92）（趋势= 0.029）。讨论：我们的结果表明，饮食镁摄入量与代谢综合征的患病率之间存在逆关联，这增加了证据表明，足够的镁摄入量或富含镁的饮食可能对维持良好的心脏计健康健康可能很重要。 。
Objective: Limited data suggest that people with the metabolic syndrome have lower intakes or circulating concentrations of magnesium than those who do not have the syndrome. The aim of this study was to examine the associations between dietary intake of magnesium and the prevalence of the metabolic syndrome in a nationally representative sample of U.S. adults.Research Methods and Procedures: We used data for 7669 participants >= 20 years of age of the Third National Health and Nutrition Examination Survey (1988 to 1994). The metabolic syndrome was defined using the criteria of the National Cholesterol Education Program. Magnesium intake was determined from a single dietary 24-hour recall.Results: The unadjusted prevalences of the metabolic syndrome were 29.0% (quintile of lowest magnesium intake), 27.5%. 25.8%. 23.9%, and 21.8% for increasing quintiles of magnesium intake (p for trend = 0.002). After multiple adjustment, the odds ratios for the second through the fifth quintiles (highest intake) of magnesium intake among all participants included in the analysis were 0.84 [95% confidence interval (Cl): 0.58, 1.23], 0.76 (95% CI: 0.54, 1.07), 0.62 (95% CI: 0.407 0.98). and 0.56 (95% CI: 0.34, 0.92), respectively (p for trend = 0.029). The associations were similar for men and women.Discussion: Our results showing an inverse association between dietary magnesium intake and the prevalence of the metabolic syndrome add to the evidence that adequate magnesium intake or a diet rich in magnesium may be important for maintaining good cardiometabolic health.
