The hypertriglyceridemic waist (HTGW) phenotype is characterized by concomitant increases in waist circumference (WC) and blood triglyceride levels (TG), which have been identified as a predictor of metabolic disorders. This study aimed to analyze associations between food consumption, exercise, and the gene rs1761667 G>A polymorphism with the HTGW phenotype in adult Mexicans. This cross-sectional study included a total of 255 participants (both genders, between 18-64 years of age). The HTGW phenotype was defined as WC >88 cm in women, WC >102 cm in men, and TG >150 mg/dL. Body composition was analyzed by electrical bioimpedance. Dietary intakes (macro and micronutrients) were evaluated through a validated 64-item food frequency questionnaire and a 24-h recall. Physical exercise was subjectively recorded asking the participants if they regularly performed some systematic exercise or sport of moderate intensity at least 150-300 minutes a week. Biochemical tests were determined by an automated system. A Taqman real-time assay was used to detect the rs1761667 (G>A) polymorphism of the gene. A multivariate logistic regression model was performed to analyze the variables potentially associated with the HTGW phenotype (adjusted for age, energy intake, and total fat mass). Overall, 21.6% of the population presented the HTGW phenotype; compared to the HTGW-, also, they were older, had more body fat, higher glucose, cholesterol and insulin levels, and high blood pressure. Female sex (OR=2.92, 95% CI: 1.12-7.60, p=0.028), body mass index (OR=1.19, 95% CI: 1.07-1.32, p=0.001), total cholesterol (OR=1.01, 95% CI:1.00-1.02, p=0.039), daily consumption of sugary drinks (OR=6.94, 95% CI: 1.80-26.8, p=0.005), and the AG genotype (OR=3.81, 95% CI: 1.08-13.4, p=0.037) were positively associated with the HTGW phenotype, while performing exercise played a protective role (OR=0.23, 95% CI: 0.08-0.62, p=0.004). Overall, the model predicted the HTGW phenotype in 47% (R=0.47, p≤0.001). The AG genotype, daily consumption of sugary drinks and sedentarism are risk factors for the HTGW phenotype in Mexicans.
高甘油三酯腰围(HTGW)表型的特征是腰围(WC)和血液甘油三酯水平(TG)同时增加,这已被确定为代谢紊乱的预测因子。本研究旨在分析墨西哥成年人的食物摄入、运动和基因 rs1761667 G>A 多态性与 HTGW 表型之间的关系。这项横断面研究共纳入了 255 名参与者(男女,年龄在 18-64 岁之间)。HTGW 表型定义为女性 WC>88cm,男性 WC>102cm,TG>150mg/dL。身体成分通过电阻抗分析进行分析。通过验证的 64 项食物频率问卷和 24 小时回顾评估饮食摄入(宏量和微量营养素)。询问参与者是否定期进行一些有规律的运动或中等强度的运动,每周至少 150-300 分钟,以记录体育锻炼情况。生化测试通过自动系统确定。使用 Taqman 实时测定法检测基因的 rs1761667(G>A)多态性。采用多变量逻辑回归模型分析与 HTGW 表型相关的潜在变量(调整年龄、能量摄入和总脂肪量)。总体而言,人群中有 21.6%存在 HTGW 表型;与 HTGW-相比,他们的年龄更大,体脂更多,血糖、胆固醇和胰岛素水平更高,且高血压更多。女性(OR=2.92,95%CI:1.12-7.60,p=0.028)、体重指数(OR=1.19,95%CI:1.07-1.32,p=0.001)、总胆固醇(OR=1.01,95%CI:1.00-1.02,p=0.039)、每日含糖饮料摄入(OR=6.94,95%CI:1.80-26.8,p=0.005)和 AG 基因型(OR=3.81,95%CI:1.08-13.4,p=0.037)与 HTGW 表型呈正相关,而运动则起到保护作用(OR=0.23,95%CI:0.08-0.62,p=0.004)。总体而言,该模型预测 HTGW 表型的准确率为 47%(R=0.47,p≤0.001)。AG 基因型、每日含糖饮料摄入和久坐不动是墨西哥人 HTGW 表型的危险因素。
