The association between hypertriglyceridemic-waist phenotype and chronic kidney disease: a cohort study and meta-analysis.

Evidence on the association between hypertriglyceridemic-waist phenotype (HTGW) and chronic kidney disease (CKD) is limited and inconsistent. We aimed to explore such association among 7406 Chinese aged ≥ 45 years in a cohort setting, followed by a meta-analysis. Participants were categorized into four phenotypes: NTNW (normal triglycerides and normal waist circumference), NTGW (isolated enlarged waist circumference), HTNW (isolated high triglycerides), and HTGW (high triglycerides and enlarged waist circumference). We used multivariate logistic regression to determine the association between different phenotypes and risk of CKD in the cohort study. For meta-analysis, we searched relevant studies from Embase, Medline, PubMed, and Web of Science from dataset inception up to May 1, 2021. A random-effect model was used to estimate the pooled effect and I2 statistic was applied to evaluate heterogeneity. In the cohort study, compared to the NTNW phenotype, HTGW (OR 1.82, 95% CI 1.32 to 2.51, p < 0.01) and NTGW (OR 1.48, 95% CI 1.13 to 1.94, p = 0.004) were significantly associated with CKD risk after 4 years follow-up, but not for the HTNW phenotype. The meta-analysis also showed a positive association between HTGW phenotype and CKD risk (pooled OR 1.53, 95% CI 1.31 to 1.79, I2 = 62.4%). Assessment of triglyceridemic-waist phenotypes might help to identify individuals with high-risk of developing CKD.

Association of "hypertriglyceridemic waist" with increased 5-year risk of subclinical atherosclerosis in a multi-ethnic population: a prospective cohort study.

BACKGROUND: Hypertriglyceridemic waist (HTGW), which incorporates measures of waist circumference and levels of triglyceride in blood, could act as an early-stage predictor to identify the individuals at high-risk for subclinical atherosclerosis. Previous studies have explored the cross-sectional association between HTGW and atherosclerosis; however, understanding how this association might change over time is necessary. This study will assess the association between HTGW with 5-year subclinical carotid atherosclerosis. METHODS: 517 participants of Aboriginal, Chinese, European, and South Asian ethnicities were examined for baseline HTGW and 5-year indices of subclinical atherosclerosis (intima media thickness (mm), total area (mm2), and plaque presence). Family history of cardiovascular disease, sociodemographic measures (age, sex, ethnicity, income level, maximum education), and traditional risk factors (systolic blood pressure, smoking status, total cholesterol, high-density lipoprotein cholesterol, body mass index) were incorporated into the models of association. These models used multiple linear regression and logistic regression. RESULTS: Baseline HTGW phenotype is a statistically significant and clinically meaningful predictor of 5-year intima media thickness (ß = 0.08 [0.04, 0.11], p < 0.001), total area (ß = 0.20 [0.07, 0.33], p = 0.002), and plaque presence (OR = 2.17 [1.13, 4.19], p = 0.02) compared to the non-HTGW group independent of sociodemographic factors and family history. However, this association is no longer significant after adjusting for the traditional risk factors of atherosclerosis (p = 0.27, p = 0.45, p = 0.66, respectively). Moreover, change in status of HTGW phenotype does not correlate with change in indices of atherosclerosis over 5 years. CONCLUSIONS: Our results suggest that when the traditional risk factors of atherosclerosis are known, HTGW may not offer additional value as a predictor of subclinical atherosclerosis progression over 5 years.

HYPERTRIGLYCERIDEMIC WAIST AND ASSOCIATED FACTORS IN CHILDREN AND ADOLESCENTS WITH TYPE 1 DIABETES MELLITUS.

OBJECTIVE: To assess the frequency of the hypertriglyceridemic waist phenotype and its associated factors in children and adolescents with type 1 diabetes mellitus. METHODS: This is an observational analytical study with individuals with type 1 diabetes mellitus, aged 5 to 18 years, of both genders, followed in a university hospital in the Brazilian Northeast. Weight, height, and waist circumference were measured, and the lipid profile and glycated hemoglobin were analyzed. The hypertriglyceridemic waist phenotype was defined by the simultaneous presence of increased waist circumference (≥90th percentile for age and gender) and elevated serum triglyceride levels (≥75 mg/dL for children and ≥90 mg/dL for adolescents). We also investigated the family history of cardiovascular diseases and diabetes, as well as sociodemographic and behavioral variables. In the statistical inference tests, the proportions were compared by Pearson's chi-square test -and/-or Fisher's exact test, being significant p<0.05. RESULTS: A total of 102 patients were evaluated, most of them females (54.9%) and adolescents (66.7%). The frequency of hypertriglyceridemic waist was 23.5%, which was associated with females (p=0.043), overweight (p=0.023), hypercholesterolemia (p=0.002), high LDL (p=0.001), and borderline VLDL (<0.001). CONCLUSIONS: The frequency of the hypertriglyceridemic waist phenotype was associated with females, atherogenic lipid profile, and overweight, indicating the importance of the nutritional monitoring of this population, aiming at reducing future cardiovascular diseases.

Métodos: Trata-se de um estudo observacional analítico com indivíduos com diabetes melito tipo 1, de cinco a 18 anos de idade, de ambos os sexos, acompanhados em um hospital universitário do Nordeste brasileiro. Foram realizadas medidas de peso, altura e circunferência da cintura, além da análise do perfil lipídico e da hemoglobina glicada. O fenótipo cintura hipertrigliceridêmica foi definido pela presença simultânea da circunferência da cintura aumentada (≥percentil 90 por idade e sexo) e dos níveis séricos de triglicerídeos elevados (≥75 mg/dL para crianças e ≥90 mg/dL para adolescentes). Investigaram-se, ainda, os antecedentes familiares para doenças cardiovasculares e diabetes, e também variáveis sociodemográficas e comportamentais. Nos testes de inferência estatística, as proporções foram comparadas pelo teste do qui-quadrado de Pearson e/ou exato de Fisher, sendo significante p<0,05. Resultados: Foram avaliados 102 pacientes, com predomínio do sexo feminino (54,9%) e de adolescentes (66,7%). A frequência de cintura hipertrigliceridêmica foi de 23,5%; a qual apresentou associação com o sexo feminino (p=0,043), excesso de peso (p=0,023), hipercolesterolemia (p=0,002), LDL elevado (p=0,001) e VLDL em valores limítrofes (<0,001). Conclusões: A frequência do fenótipo cintura hipertrigliceridêmica foi associada ao sexo feminino, ao perfil lipídico aterogênico e ao excesso ponderal, evidenciando a importância do acompanhamento nutricional dessa população, visando à redução de agravos cardiovasculares futuros.

Association of the hypertriglyceridemic waist phenotype and severity of acute pancreatitis.

BACKGROUND: The aim of this study was to evaluate the effect of a simple visceral obesity phenotype, known as the hypertriglyceridemic waist phenotype and its quantitative indicator waist circumference index on the severity of acute pancreatitis. MATERIALS AND METHODS: Diagnosis and severity analysis of acute pancreatitis were determined according to the Atlanta classification guidelines, revised in 2012. We considered the hypertriglyceridemic waist phenotype as characterized by increased waist circumference and elevated triglyceride concentrations. We investigated the association between the acute pancreatitis severity and hypertriglyceridemic waist phenotype, including waist circumference index. RESULTS: The hypertriglyceridemic waist phenotype was significantly associated with systemic inflammatory response syndrome, organ failure, and severe acute pancreatitis. The median waist circumference index and demonstration of hypertriglyceridemic waist phenotype were positively correlated with acute pancreatitis severity. In addition, multivariate logistic analysis showed that patients with the hypertriglyceridemic waist phenotype had 1.664 times the risk of organ failure and 1.891 times the risk of systemic inflammatory response syndrome, compared with the other groups. CONCLUSION: Upon admission, the hypertriglyceridemic waist phenotype was strongly associated with acute pancreatitis in patients. This phenotype, including waist circumference index, might be a simple method for evaluating individuals at high risk of severe acute pancreatitis.

Hypertriglyceridemic waist phenotype and nutritional factors: a study with participants of ELSA-Brasil. / Fenótipo da cintura hipertrigliceridêmica e fatores nutricionais: um estudo com participantes do ELSA-Brasil.

OBJECTIVE: To investigate the association between fat and fiber intakes and the hypertriglyceridemic waist phenotype (HWP). METHODS: Cross-sectional survey conducted from the baseline of Brazilian Longitudinal Study of Health Adult (ELSA-Brasil). Anthropometric measurements were conducted and the body mass index was calculated (BMI). Participants were classified according to the presence of HWP when waist circumference ≥ 102 and ≥ 88 cm, respectively, in men and women, and triglycerides ≥ 150 mg/dL. Fat and fiber intakes were assessed using a validated food frequency questionnaire, and socioeconomic, demographic and behavioral variables were collected through a questionnaire. The χ² test, Mann-Whitney and Poisson regression were performed with significance level of 5%. RESULTS: There was no association between fiber and fat intakes with HWP. A lower prevalence of HWP among men was observed (IRR = 0.959; 95%CI 0.948 - 0.969). A higher prevalence of HWP was observed in participants with low physical activity (OR = 1.039, 95%CI 1.021 - 1.057), smoking history (OR = 1.044, 95%CI 1.031 - 1.057), lower per capita income (IRR = 1.035; 95%CI 1.022 - 1.049) and obesity (OR = 1.32, 95%CI 1.305 - 1.341). Fat and fiber intakes were not associated with HWP. CONCLUSION: A higher prevalence of HWP was found in obese, but no association was found between intake of fat and fiber and phenotype.

Hypertriglyceridemic Waist Phenotype and Changes in the Fasting Glycemia and Blood Pressure in Children and Adolescents Over One-Year Follow-Up Period / Fenótipo Cintura Hipertrigliceridêmica e mudanças na glicemia de jejum e pressão arterial de crianças e adolescentes após um ano de seguimento

Abstract Background: The hypertriglyceridemic waist (HTW) phenotype is defined as the simultaneous presence of increased waist circumference (WC) and serum triglycerides (TG) levels and it has been associated with cardiometabolic risk in children and adolescents. Objective: The objective was to evaluate the influence of HTW phenotype in the fasting glycemia and blood pressure in children and adolescents over one-year follow-up period. Methods: It is a cohort study involving 492 children and adolescents from 7 to 15 years old, both genders, who were submitted to anthropometric, biochemical and clinical evaluation at the baseline, and also after 6 and 12 months of follow-up. Generalized Estimating Equation (GEE) models were calculated to evaluate the longitudinal influence of the HTW phenotype in the glycemia and blood pressure over one-year. Results: It was observed a prevalence of 10.6% (n = 52) of HTW phenotype in the students. The GEE models identified that students with HTW phenotype had an increase of 3.87 mg/dl in the fasting glycemia mean (CI: 1.68-6.05) and of 3.67mmHg in the systolic blood pressure (SBP) mean (CI: 1.55-6.08) over one-year follow-up, after adjusting for confounding variables. Conclusions: The results of this study suggest that HTW phenotype is a risk factor for longitudinal changes in glycemia and SBP in children and adolescents over one-year follow-up period.

Las medidas antropométricas como indicadores predictivos de riesgo metabólico en una población mexicana / Anthropometric measurements as predictive indicators of metabolic risk in a Mexican population

Introducción: actualmente se considera que la acumulación de grasa corporal a nivel central se asocia con la presencia de hipertrigliceridemia, hipertensión arterial y diabetes. El índice de masa corporal (IMC) se ha utilizado para identificar la obesidad en la población general, pero no permite determinar la distribución de la grasa corporal, por lo que se pueden utilizar otras medidas antropométricas para evaluar la adiposidad y determinar su relación con la presencia de alteraciones metabólicas que presentan las personas con exceso de peso. Objetivo: evaluar las medidas antropométricas como el índice cintura-cadera (ICC), IMC y circunferencia de cintura (CC) como indicadores predictivos de factores de riesgo metabólico en población mexicana adulta. Métodos: se realizó un estudio transversal descriptivo en un total de 490 personas (27-46 años), agrupadas por género. A todos los participantes se les determinaron medidas antropométricas y parámetros bioquímicos. Se crearon curvas ROC de los parámetros antropométricos para identificar el mejor indicador predictivo de riesgo metabólico. Resultados: el factor de riesgo metabólico con mayor prevalencia después de la obesidad abdominal en mujeres fue la hipertrigliceridemia, seguido de la hiperglicemia, hipercolesterolemia y presión arterial elevada, que se encontraron con mayor frecuencia en los hombres, aunque la presencia de obesidad abdominal se encontró con mayor frecuencia en las mujeres (73,9 vs. 37,3 %). La circunferencia de cintura fue el mejor indicador predictivo para presentar uno o más factores de riesgo metabólico [área bajo la curva ABC = 0,85 (IC 95%, 0,78-0,92)], seguido del IMC [ABC = 0,79 (IC 95%, 0,72-0,88)] y por último el ICC [ABC = 0,63 (IC 95%, 0,52-0,74)]. Además, se observó que la obesidad abdominal duplica el riesgo de presentar el síndrome metabólico. Conclusión: la circunferencia de cintura es el mejor indicador de riesgo metabólico en ambos sexos en comparación con el IMC y el ICC (AU)

Introduction: Currently, it is considered that the body fat accumulation at central level is associated with the presence of hypertriglyceridemia, hypertension and diabetes. The body mass index (BMI) has been used to identify obesity in the general population, but can not detect the distribution of body fat, so that can be used other anthropometric measures to assess adiposity and determine their relationship with the presence of metabolic disorders that present people with excess weight. Objective: To evaluate anthropometric measurements such as waist-hip ratio (WHR), BMI and waist circumference (WC) as predictive indicators of metabolic risk factors in Mexican adults. Methods: A descriptive cross-sectional study was conducted in a total of 490 subjects (27-46 years), grouped by gender. All participants were determined anthropometric measurements and biochemical parameters. ROC curves of anthropometric parameters were set to identify the best predictive indicator of metabolic risk. Results: The metabolic risk factor most prevalent after abdominal obesity in women was hypertriglyceridemia, followed by hyperglycemia, hypercholesterolemia and high blood pressure, which are found most often in men than in women, although the presence of abdominal obesity was found most frequently in women (73.9% vs. 37.3%). WC was the best predictive indicator to have one or more metabolic risk factors [area under the curve AUC = 0.85 (95% CI, 0.78 to 0.92)], followed by the BMI [AUC = 0.79 (95% CI, 0.72 to 0.88)], and finally the WHC [AUC = 0.63 (95% CI, 0.52 to 0.74)]. Also shows that abdominal obesity duplicate the risk of metabolic syndrome. Conclusion: Waist circumference is a better indicator of metabolic risk in both genders compared with BMI and the WHC (AU)

Hypertriglyceridemic waist phenotype and metabolic abnormalities in hypertensive adults: A STROBE compliant study.

The aim of this study was to evaluate the relationship between the hypertriglyceridemic waist (HTGW) phenotype and metabolic abnormalities in hypertensive adults.A cross-sectional study, with a sample of 5919 hypertensive adults (2892 men and 3027 women) aged 35 years or older, was recruited from rural areas of China. The participants underwent anthropometric measurements and laboratory examinations. The self-reported information was collected by trained personnel. The HTGW phenotype was defined as elevated triglycerides and elevated waist circumference. The logistic regression analysis was used to evaluate the associations of interest.Hypertensive adults with the HTGW phenotype had significantly higher prevalences of all cardiometabolic risk factors than those without the HTGW phenotype (P < 0.001). Compared with the normal waist normal triglyceride (NWNT) group, hypertensive adults with the HTGW phenotype had much higher possibilities to have all cardiometabolic risk factors, especially for 8.35 times more likely of having ≥3 cardiometabolic risk factors [95% confidence interval (95% CI) 5.92-11.79], 6.14 times more likely of having low HDL cholesterol (95% CI 4.98-7.58), 5.49 times more likely of having hyperuricemia (95% CI 4.40-6.86), and 4.32 times more likely of having 1 to 2 cardiometabolic risk factors (95% CI 3.68-5.07) (P < 0.001). Multivariate analysis indicated that the HTGW phenotype was positively associated with metabolic abnormalities (P < 0.05).This study concluded that the HTGW phenotype was positively associated with metabolic abnormalities in hypertensive adults. The HTGW phenotype showed to be an important tool for monitoring of hypertensive adults with metabolic abnormalities, which is low cost, simple, and useful in clinical practice, especially in primary health care in the rural area of China.

Utility of hypertriglyceridemic waist phenotype for predicting incident type 2 diabetes: The Isfahan Diabetes Prevention Study.

AIM/INTRODUCTION: We evaluated the association between hypertriglyceridemic waist (HTW) phenotype and the risks of type 2 diabetes in an Iranian high-risk population. MATERIALS AND METHODS: We analyzed 7-year follow-up data (n = 1,865) in non-diabetic first-degree relatives of consecutive patients with type 2 diabetes aged 30-70 years. The primary outcome was the diagnosis of type 2 diabetes based on repeated oral glucose tolerance tests. We used multiple logistic regressions to estimate the odds ratio (OR) for incident type 2 diabetes across four groups according to baseline fasting serum triglycerides (TG) level and waist circumference (WC): normal WC and normal TG, normal WC and high TG, enlarged WC and normal TG, and HTW (enlarged WC high TG). RESULTS: The HTW phenotype at baseline was associated with the incidence of type 2 diabetes. Those with HTW were 2.4-fold (OR 2.36, 95% confidence interval 1.61-3.44), those with normal WC high TG were 1.9-fold (OR 1.87, 95% confidence interval 1.29-2.70) and those with enlarged WC but normal TG were 2.8-fold (OR 2.84, 95% confidence interval 1.96-4.13) more likely to develop type 2 diabetes than those with normal WC and normal TG. CONCLUSIONS: These data provide further evidence that the HTW phenotype is a robust predictor of type 2 diabetes in high-risk individuals in Iran, and the predictive power is not higher than that of simple enlarged WC and normal TG, emphasizing the importance of enlarged WC to the development of type 2 diabetes.

Hypertriglyceridemic waist - a simple clinical tool to detect cardiometabolic risk: comparison with harmonized definition of metabolic syndrome.

With the increasing prevalence of obesity and especially abdominal obesity, a simple clinical tool is needed that identifies the cardiometabolic risk for cardiovascular disease and type 2 diabetes. The aim of our study was to evaluate a broad spectrum of metabolic variables and IMT in subjects with and without hypertriglyceridemic waist (HTGW) and compare it with the harmonized definition of metabolic syndrome (MS) with both a higher (MS-I) and lower waist circumference (MS-II) for Europids. We enrolled 607 asymptomatic dyslipidemic subjects (295 men and 312 women) into our cross-sectional study. The subjects with HTGW had an atherogenic lipid profile (significantly higher triglycerides, AIP, non-HDL-C, lower HDL-C and ApoA-1, and the women also higher TC and ApoB), increased markers of insulin resistance (insulin, HOMA, C-peptide, proinsulin), inflammation (hsCRP), thrombosis (fibrinogen, PAI-1), SBP and DBP, and lower adiponectin (p<0.05-0.001 for all). These risk factors were entirely similar in HTGW, MS-I and MS-II. Age-adjusted IMT was significantly higher only in the women with HTGW but this significance disappeared after further adjustment for TC, SBP, and smoking. Our results support the routine use of HTGW as a simple and inexpensive screening tool to detect subjects at increased cardiometabolic risk in clinical practice.

[Anthropometric indices to identify metabolic syndrome and hypertriglyceridemic waist phenotype: a comparison between the three stages of adolescence]. / Indicadores antropométricos para identificar síndrome metabólica e fenótipo cintura hipertrigliceridêmica: uma comparação entre as três fases da adolescência.

OBJECTIVE: To determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age. METHODS: This cross sectional study had the participation of 800 adolescents (414 girls) from 10-19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve. RESULTS: The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17-19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype. CONCLUSIONS: The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.

Waist-to-height ratio as a screening measure for identifying adolescents with hypertriglyceridemic waist phenotype.

OBJECTIVE: The purpose of the present study was to investigate the relationship between waist-to-height ratio (WHtR) and the hypertriglyceridemic waist (HTGW) phenotype to test the hypothesis that WHtR can identify adolescents at high risk of the HTGW phenotype. METHODS: In 2006, anthropometric measurements were assessed in a cross-sectional population-based study of 3136 Han adolescents aged 13-17 years. Blood samples were collected to measure triacylglycerol concentrations. WHtR was calculated by waist circumference/height. The HTGW phenotype was represented by the simultaneous presence of elevated serum triglycerides and increased waist circumference. The ability of WHtR to accurately define the HTGW phenotype was assessed by area under the curve (AUC). RESULTS: The prevalence of the HTGW phenotype was 3.3% (boys 3.6% vs. girls 2.9%, χ2=1.424, p=0.233). The prevalence of the HTGW phenotype increased with WHtR (p<0.001). The accuracy of WHtR in the identification of the HTGW phenotype (as assessed by AUC) was over 0.85, both in boys and girls (AUC: 0.956 in boys and 0.961 in girls). WHtR cutoff values, chosen to maximize sensitivity plus specificity, for the HTGW phenotype were calculated to be 0.48 in boys and 0.46 in girls. The sensitivities were 98.3% in boys and 97.7% in girls. The specificities were 88.0% in boys and 86.8% in girls. CONCLUSIONS: WHtR is simpler than the HTGW phenotype and does not require blood tests. The prevalence of the HTGW phenotype increased with WHtR. Higher WHtR can identify adolescents with high risk of the HTGW phenotype.

Hypertriglyceridemic waist: the point of divergence for prediction of CVD vs. mortality: Tehran Lipid and Glucose Study.

AIMS: We examined hypertriglyceridemic waist (HTGW) predictability for CVD and mortality. METHODS: Among Tehran Lipid and Glucose Study's participants aged ≥30 (n=8071), we selected those who participated in the follow-up study until 20-March-2009 (n=7154). After exclusions (320 missing data on waist circumference or triglycerides), 6834 (3830 women) participants remained eligible with a total of 59,873 person-year follow-up. When CVD was outcome, we further excluded 426 participants with history of previous CVD. RESULTS: All-cause mortality, CVD mortality, and incident CVD rate among men (per 1000-person-year) were 7.9 (95% CIs: 6.9-9.1), 4.1 (95% CIs: 3.4-5.0), and 13.0 (95% CIs: 11.7-14.6), respectively. Among women, corresponding figures were 3.7 (95% CIs: 3.1-4.4), 1.7 (95% CIs: 1.3-2.1), and 7.3 (95% CIs: 6.4-8.3), respectively. After adjustment for potential confounders, HTGW came to be inversely associated with all-cause mortality among both men (HR 0.384, 95% CIs 0.281-0.526) and women (HR 0.642, 95% CIs 0.430-0.958). Multivariate adjusted HR (95% CIs) of HTGW for CVD mortality was 0.453 (95% CIs 0.298-0.688) among men and 0.760 (95% CIs 0.431-1.338) among women. HTGW increased the age-adjusted risk of incident CVD, among both men (40%) and women (97%). The multivariate hazard ratio of HTGW for incident CVD was 0.945 (95% CIs 0.746-0.1.198, P value=0.640) among men and 1.470 among women (HR 95% CIs 1.111-1.944, P value=0.007). CONCLUSION: HTGW was the point of divergence for prediction of CVD vs. mortality. HTGW, despite its predictive value for CVD, might not help in capturing risk of all-cause or CVD mortality. Individuals without HTGW constitute a heterogeneous subgroup with a jumble of risk factors that put them at risk for all-cause or CVD mortality.

Hypertriglyceridemic waist is associated with increased carotid atherosclerosis in chronic kidney disease patients.

BACKGROUND: Patients with chronic kidney disease (CKD) have an unacceptably high risk of death, primarily as a result of cardiovascular disease (CVD). The 'hypertriglyceridemic waist' phenotype has been proposed as a simple and strong predictor of CVD risk. Therefore, we investigated the relationship between the hypertriglyceridemic waist phenotype and carotid atherosclerosis in CKD patients. METHODS: In a cross-sectional study, we enrolled 785 prevalent CKD patients [416 males, aged 44.6 years (21.7-69.4), glomerular filtration rate 52.5 ml/min/1.73 m(2) (5.3-119.4)]. We divided the patients into three groups: group 1: waist circumference >90 cm in men or >85 cm in women and triglycerides ≥2 mmol/l (n = 109); group 3: waist circumference ≤90 cm in men or ≤85 cm in women and triglycerides <2 mmol/l (n = 379), and group 2: the remaining patients (n = 297). Routine biochemical parameters and carotid artery intima-media thickness (IMT) were measured. RESULTS: The prevalence of the hypertriglyceridemic waist phenotypes was 13.8% in the CKD patients. Triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol concentrations in group 1 were significantly higher than those in group 3. Carotid artery IMT of the hypertriglyceridemic waist group was the highest. CONCLUSION: The hypertriglyceridemic waist phenotype was associated with worse carotid atherosclerosis in CKD patients. This suggests that the hypertriglyceridemic waist phenotype may be useful for predicting CVD risk in CKD patients.
