Little is known about the relationship between diet and metabolic health in Latino children, a population at increased risk for diabetes. The present study evaluates diet composition and the metabolic syndrome in a cross-sectional sample of 109 overweight Latino children aged 10 to 17 years with a family history of type 2 diabetes. Dietary intake was assessed by two 24-hour recalls. Associations between nutrients and features of the metabolic syndrome were examined using multiple linear regression and analysis of covariance. Log cholesterol intake was positively associated with log systolic blood pressure (beta=0.034, P=0.017) and log soluble dietary fiber intake was inversely associated with log waist circumference (beta=-0.069, P=0.036). Log soluble fiber intake was significantly higher in participants with 0 features compared to those with 3+ features of the metabolic syndrome (P=0.046), which translates to 5.2 g vs 4.1 g soluble fiber daily. No other significant associations were found between dietary variables and either the individual features of the metabolic syndrome or the clustering of metabolic syndrome components. Increases in soluble fiber through the daily consumption of fruits, vegetables, and beans may improve metabolic health in Latino children.
关于拉丁裔儿童的饮食与代谢健康之间的关系，人们所知甚少，而该人群患糖尿病的风险较高。本研究评估了109名10至17岁、有2型糖尿病家族史的超重拉丁裔儿童横断面样本中的饮食组成和代谢综合征。通过两次24小时饮食回顾来评估饮食摄入量。使用多元线性回归和协方差分析来检验营养素与代谢综合征特征之间的关联。对数胆固醇摄入量与对数收缩压呈正相关（β=0.034，P=0.017），对数可溶性膳食纤维摄入量与对数腰围呈负相关（β=-0.069，P=0.036）。与具有3种及以上代谢综合征特征的参与者相比，具有0种特征的参与者的对数可溶性纤维摄入量显著更高（P=0.046），这相当于每日可溶性纤维摄入量分别为5.2克和4.1克。在饮食变量与代谢综合征的个体特征或代谢综合征组分聚集之间未发现其他显著关联。通过每日食用水果、蔬菜和豆类增加可溶性纤维摄入量，可能会改善拉丁裔儿童的代谢健康。
