Association of hypertriglyceridemic waist phenotype with metabolic syndrome traits and its diagnostic potential to predict metabolic syndrome in adults with excess body weight: A community‐based cross‐sectional study.

Background: The hypertriglyceridemic waist (HTGW) phenotype is a simple measure to identify individuals at increased risk of metabolic syndrome (MetS) traits. The present study aimed to describe the HTGW prevalence, and its associations with MetS traits, and also determine the diagnostic potential of the mirror indices of HTGW phenotype to predict MetS and its components in community‐dwelling adults with overweight or obesity in Southern, Sri Lanka. Methods: In a cross‐sectional study, 300 adults with excess body weight (body mass index >23 kg/m2) were enrolled and examined for the HTGW phenotype (fasting plasma triglyceride concentration ≥1.695 mmol/L and waist circumference >90 and >85 cm in males and females, respectively). Results: One in five adults with excess body weight had the HTGW phenotype. Phenotype‐positive adults had significantly higher fasting plasma glucose (FPG) (p = 0.010), low‐density lipoprotein cholesterol (HDL‐C) (p < 0.001), total cholesterol (p < 0.001), atherogenic index (p < 0.001), coronary risk index (p = 0.001), triglyceride glucose index (p = 0.040), bioimpedance visceral fat (p = 0.041) and significantly lower HDL‐C (p = 0.001) and cardioprotective index (p = 0.009) than those without the HTGW phenotype. Adults with excess body weight and the HTGW phenotype had an increased risk of FPG (odds ratio [OR] = 1.294; 95% confidence interval [CI] 1.051–1.594), atherogenic index (OR = 3.138; 95% CI = 1.559–6.317) and triglyceride glucose index (OR = 3.027; 95% CI = 1.111–8.249). The HTGW phenotype was strongly associated with MetS traits (OR = 16.584; 95% CI = 6.230–44.147). The cut‐off values for the product of waist circumference × triglyceride, to identify the risk of having MetS and dyslipidemia among adults with excess body weight were 158.66 and 160.15 cm × mmol/L, respectively. Conclusions: The readily available and inexpensive measures of the HTGW phenotype could serve as a clinically useful marker to identify MetS traits in adults with excess body weight. Highlights: The prevalence of the hypertriglyceridemic waist (HTGW) phenotype in adults with excess body weight was 20%.Adults with excess body weight and HTGW phenotype had significantly higher fasting plasma glucose (FPG), low‐density lipoprotein cholesterol, total cholesterol, atherogenic index, coronary risk index, triglyceride glucose index and visceral fat, as well as significantly lower high‐density lipoprotein cholesterol and cardioprotective index, than those without the phenotype.Adults with excess body weight and HTGW phenotype had an increased risk of FPG, atherogenic index, triglyceride glucose index and metabolic syndrome traits.The cut‐off values for the product of waist circumference × triglyceride, with the aim of identifying the risk of having metabolic syndrome and dyslipidemia among adults with excess body weight, were 158.66 and 160.15 cm × mmol/L, respectively.
