This study aimed to evaluate the associations between the muscle mass to visceral fat (MVF) ratio and cardiometabolic risk factors in a large population of college students in Colombia and to propose cut-off points of this index for the metabolic syndrome (MetS). A total of 1464 young adults recruited from the FUPRECOL (Asociación de la Fuerza Prensil con Manifestaciones Tempranas de Riesgo Cardiovascular en Jóvenes y Adultos Colombianos) study were categorised into four groups based on their MVF ratio. Muscle mass and visceral fat level of the participants were measured using a bioelectrical impedance analysis. Cardiometabolic risk factors including lifestyle characteristics, anthropometry, blood pressure and biochemical parameters were assessed. The prevalence of moderate to severe obesity, hypertension and the MetS was higher in subjects in quartile (Q)1 (lower MVF ratio) (P <0·001). ANCOVA revealed that the subjects in Q1 had higher cardiometabolic disturbances, including altered anthropometry, blood pressure, muscle strength and biochemical parameters after adjusting for age and sex compared with young adults in higher MVF ratio quartiles (P <0·001). Muscular mass and physical activity levels were significantly lower in subjects with a lower MVF ratio (P <0·001). The receiver operating characteristic curve analyses indicated that in men the best MVF ratio cut-off point for detecting the MetS was 18·0 (AUC 0·83, sensitivity 78 % and specificity 77 %) and for women, the MVF ratio cut-off point was 13·7 (AUC 0·85, sensitivity 76 % and specificity 87 %). A lower MVF ratio is associated with a higher risk cardiometabolic profile in early adulthood, supporting that the MVF ratio could be used as a complementary screening tool that may help clinicians identify young adults at high cardiometabolic risk.
本研究旨在评估哥伦比亚大量大学生群体中肌肉量与内脏脂肪(MVF)比值与心血管代谢危险因素之间的关联,并提出该指标用于代谢综合征(MetS)的切点。从FUPRECOL(哥伦比亚青年和成年人早期心血管风险与握力协会)研究中招募的1464名年轻成年人,根据其MVF比值分为四组。采用生物电阻抗分析测量参与者的肌肉量和内脏脂肪水平。评估了包括生活方式特征、人体测量学、血压和生化参数在内的心血管代谢危险因素。四分位数(Q)1(MVF比值较低)的受试者中,中度至重度肥胖、高血压和MetS的患病率较高(P<0.001)。协方差分析显示,与MVF比值较高四分位数的年轻成年人相比,Q1组受试者在调整年龄和性别后,心血管代谢紊乱更为严重,包括人体测量学、血压、肌肉力量和生化参数改变(P<0.001)。MVF比值较低的受试者肌肉量和身体活动水平显著较低(P<0.001)。受试者工作特征曲线分析表明,男性检测MetS的最佳MVF比值切点为18.0(曲线下面积0.83,灵敏度78%,特异性77%),女性的MVF比值切点为13.7(曲线下面积0.85,灵敏度76%,特异性87%)。较低的MVF比值与成年早期较高的心血管代谢风险相关,支持MVF比值可作为一种辅助筛查工具,帮助临床医生识别心血管代谢高风险的年轻成年人。
