Examine the prospective association among diet with adolescent cardiometabolic risk (CMR) and anthropometrics.
Secondary analysis of an observational study of adolescents aged 10-16 years. Twenty-four-hour food recalls were used to calculate Healthy Eating Index-2015 (HEI-2015) scores. Anthropometrics were assessed using magnetic resonance imaging, dual-energy x-ray absorptiometry, and height/weight measurements. CMR included mean arterial pressure, homeostatic model assessment for insulin resistance, high-density lipoprotein cholesterol, and triglycerides. Associations between HEI-2015 score at baseline with follow-up adiposity and CMR were examined using regression models.
A total of 192 adolescents were included. Baseline HEI-2015 scores were inversely associated with follow-up total CMR z-score (P = 0.01), homeostatic model assessment for insulin resistance (P < 0.01), waist circumference z-score (P = 0.02), body mass index percentile (P = 0.01), fat mass (P = 0.04), lean mass (P = 0.02), and visceral adipose tissue mass (P = 0.01).
Adolescents with lower adherence to dietary guidelines and greater CMR and anthropometry measurements at baseline continued this trajectory across the observation.
研究青少年心血管代谢风险（CMR）和人体测量指标与饮食之间的前瞻性关联。
对 10-16 岁青少年的观察性研究进行二次分析。采用 24 小时食物回顾法计算健康饮食指数-2015（HEI-2015）评分。采用磁共振成像、双能 X 射线吸收法和身高/体重测量评估人体测量学。CMR 包括平均动脉压、胰岛素抵抗的稳态模型评估、高密度脂蛋白胆固醇和甘油三酯。使用回归模型检查基线时 HEI-2015 评分与随访肥胖和 CMR 之间的关联。
共纳入 192 名青少年。基线时 HEI-2015 评分与随访时总 CMR z 评分呈负相关（P = 0.01）、胰岛素抵抗的稳态模型评估（P < 0.01）、腰围 z 评分（P = 0.02）、体重指数百分位数（P = 0.01）、脂肪量（P = 0.04）、瘦体重（P = 0.02）和内脏脂肪组织量（P = 0.01）。
基线时饮食指南依从性较低、CMR 和人体测量指标较高的青少年在整个观察期间继续保持这种趋势。
