Predictive cut-off values for the triglyceride-to-high-density lipoprotein cholesterol ratio to predict metabolic syndrome in the middle-aged Korean population. Nutr Metab Cardiovasc Dis 2024; 34:882-892. [PMID: 38413357 DOI: 10.1016/j.numecd.2024.01.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 01/04/2024] [Accepted: 01/22/2024] [Indexed: 02/29/2024]
Abstract
BACKGROUND AND AIMS The triglyceride-to-high density lipoprotein cholesterol (TG/HDL) ratio is associated with insulin resistance related diseases, including metabolic syndrome (MetS). However, specific TG/HDL values that can predict MetS have not been well identified. In this study, we analyzed both cross-sectional and longitudinal data from two national Korean datasets to obtain TG/HDL cut-off values that can identify MetS and predict its occurrence. METHODS AND RESULTS To distinguish the presence and occurrence of MetS, the cut-off values were determined using the maximum F-score calculated through a logistic regression analysis. To predict new-onset MetS within 10 years, Cox proportional hazard models were used to consider the time of occurrence. The TG/HDL cut-off values of 3.97, 3.24, and 3.24 were optimal for identifying current MetS and predicting new-onset MetS within 10 years and five years, respectively, in Korean men. In Korean women, the optimal values for each task were 3.18, 2.38, and 2.26, respectively. CONCLUSIONS We suggest the TG/HDL ratio as a potential candidate predictor for MetS. Therefore, we anticipate that future studies will apply individual lipid levels as well as their combinatory values to establish models that predict the prevalence and occurrence of MetS, diabetes, and cardiovascular disease.

Association of triglyceride/high-density lipoprotein cholesterol ratio with severe complications of COVID-19. Heliyon 2023; 9:e17428. [PMID: 37366523 PMCID: PMC10275776 DOI: 10.1016/j.heliyon.2023.e17428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 06/13/2023] [Accepted: 06/16/2023] [Indexed: 06/28/2023] Open
Abstract
Background The coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus can lead to serious complications such as respiratory failure, requiring mechanical ventilation or ICU care, and can even result in death, especially in older patients with comorbidities. The ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL), a biomarker of atherosclerotic dyslipidemia and insulin resistance, is related to cardiovascular mortality and morbidity. We aimed to evaluate the link between serious complications of COVID-19 and TG/HDL in the general population. Methods We conducted a comprehensive analysis of 3,933 COVID-19 patients from a nationwide cohort in Korea spanning from January 1 to June 4, 2020. TG/HDL ratio was calculated from the national health screening examination data underwent before the COVID-19 infection. Serious complications of COVID-19 were defined as a composite of high-flow oxygen therapy, mechanical ventilation, admission to the intensive care unit (ICU), and mortality. We employed logistic regression analysis to investigate the relationship between the TG/HDL ratio and the likelihood of developing severe complications within 2 months of the diagnosis. To visualize this association, we used a smoothing spline plot based on the generalized additive regression model. Multivariate analysis was performed with adjustment for age, gender, body mass index, lifestyle measures, and comorbidities. Results Among the 3,933 COVID-19 patients, the proportion of serious complications was 7.53%. Regarding individual outcomes, the number of patients who received high-flow oxygen therapy, mechanical ventilation, ICU care, and died was 84 (2.14%), 122 (3.10%), 173 (4.40%), and 118 (3.00%), respectively. In the multivariable logistic regression, a positive association was found between TG/HDL ratio and serious complications of COVID-19 (adjusted OR, 1.09; 95% CI [1.03-1.15], p = 0.004). Conclusion Our study revealed a significant positive association between TG/HDL ratio and the risk of developing severe complications in COVID-19-infected patients. While this finding provides valuable insight into the potential prognostic role of TG/HDL ratio in COVID-19, further studies are needed to fully elucidate the underlying mechanisms behind this relationship.

Serum Triglyceride to High-Density Lipoprotein Ratio as a Marker of Insulin Resistance Among 5-15-Year-Old Sri Lankan Children in an Urban Setting. Metab Syndr Relat Disord 2023. [PMID: 37220003 DOI: 10.1089/met.2022.0086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/25/2023] Open
Abstract
Objective: Prevalence of insulin resistance (IR) among South Asian populations is relatively high. It increases with the obesity epidemic. Since determining IR is costly, triglyceride to high-density lipoprotein (TG/HDL) ratio has shown to be a good proxy marker for IR in adults. However, it is not yet well established in children. This study aimed to assess TG/HDL ratio as a marker of IR in 5-15-year-old children in Colombo District of Sri Lanka. Methods: A cross-sectional descriptive study was conducted among 309 school children 5-15 years of age, selected using two-stage probability-proportionate-to-size cluster sampling technique. Sociodemographic data, and anthropometric and biochemical parameters were obtained. After a 12-hr overnight fast, blood was taken for biochemical investigations. Results: Three hundred nine children (173 girls) were recruited. Mean age of girls was 9.9 years and boys 10.3 years. Based on body mass index (BMI) z-score, 15.3% were overweight and 6.1% were obese. Metabolic syndrome was present in 2.3% of children and IR based on Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) ≥2.5 in 7.5%. Mean TG/HDL ratio, waist circumference (WC), hip circumference (HC), BMI, waist-to-height-ratio (WHtR), and body fat percentage were significantly higher (P < 0.01) among children with IR compared with non-IR children. TG/HDL ratio significantly correlated with BMI, % fat mass, WC, HC, WHtR, and HOMA-IR. TG/HDL ratio is an independent risk factor in determining IR. The cutoff value of TG/HDL ratio ≥3 had higher specificity (89.8%) but lower sensitivity (47.8%) for detection of IR. TG/HDL ratio >1.5 had a higher sensitivity (82.6%) but lower specificity (47.7%). Conclusions: TG/HDL ratio is a good proxy marker of IR among 5-15-year-old children. A cutoff value of ≥1.5 had satisfactory sensitivity and specificity.

TG/HDL Ratio Is an Independent Predictor for Estimating Resting Energy Expenditure in Adults with Normal Weight, Overweight, and Obesity. Nutrients 2022; 14:nu14235106. [PMID: 36501139 PMCID: PMC9741411 DOI: 10.3390/nu14235106] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 12/02/2022] Open
Abstract
Factors that determine resting energy expenditure (REE) remain under investigation, particularly in persons with a high body mass index (BMI). The accurate estimation of energy expenditure is essential for conducting comprehensive nutrition assessments, planning menus and meals, prescribing weight and chronic disease interventions, and the prevention of malnutrition. This study aimed to: (a) determine the contribution of cardiometabolic biomarkers to the inter-individual variation in REE in persons categorized by BMI; and (b) assess the contribution of these biomarkers in the prediction of REE when persons of varying BMI status were categorized by their glycemic and metabolic syndrome status. Baseline data from 645 adults enrolled in diet intervention trials included REE measured by indirect calorimetry, body composition by dual energy X-ray absorptiometry, anthropometrics, and cardiometabolic biomarkers. Multivariate linear regression modeling was conducted to determine the most parsimonious model that significantly predicted REE by BMI category, metabolic syndrome status, and glycemic status. Modeling with the traditional predictors (age, sex, height, weight) accounted for 58-63% of the inter-individual variance in REE. When including age, sex, height, weight and fat-free mass as covariates, adding TG/HDL to regression modeling accounted for 71-87% of the variance in REE. The finding that TG/HDL is an independent predictor in estimating REE was further confirmed when participants were categorized by metabolic syndrome status and by glycemic status. The clinical utility of calculating the TG/HDL ratio not only aids health care providers in identifying patients with impaired lipid metabolism but can optimize the estimation of REE to better meet therapeutic goals for weight and disease management.

Modulation of Dyslipidemia Markers Apo B/Apo A and Triglycerides/HDL-Cholesterol Ratios by Low-Carbohydrate High-Fat Diet in a Rat Model of Metabolic Syndrome. Nutrients 2022; 14:nu14091903. [PMID: 35565871 PMCID: PMC9102123 DOI: 10.3390/nu14091903] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 04/27/2022] [Accepted: 04/28/2022] [Indexed: 02/01/2023] Open
Abstract
Metabolic syndrome (MetS) risks cardiovascular diseases due to its associated Dyslipidemia. It is proposed that a low-carbohydrate, high-fat (LCHF) diet positively ameliorates the MetS and reverses insulin resistance. Therefore, we aimed to investigate the protecting effect of the LCHF diet on MetS-associated Dyslipidemia in an experimental animal model. Forty male Sprague-Dawley rats were divided into four groups (10/group): the control group, dexamethasone-induced MetS (DEX) (250 µg/kg/day), LCHF-fed MetS group (DEX + LCHF), and High-Carbohydrate-Low-Fat-fed MetS group (DEX + HCLF). At the end of the four-week experiment, fasting glucose, insulin, lipid profile (LDL-C, HDL-C, Triglyceride), oxidized-LDL, and small dense-LDL using the ELISA technique were estimated. HOMA-IR, Apo B/Apo A1 ratio, and TG/HDL were calculated. Moreover, histological examination of the liver by H & E and Sudan III stain was carried out. In the DEX group, rats showed a significant (p < 0.05) increase in the HOMA-IR, atherogenic parameters, such as s-LDL, OX-LDL, Apo B/Apo A1 ratio, and TG/HDL. The LCHF diet significantly improved the parameters of Dyslipidemia (p < 0.05) by decreasing the Apo B/Apo A1 and TG/HDL-C ratios. Decreased steatosis in LCHF-fed rats compared to HCLF was also revealed. In conclusion, the LCHF diet ameliorates MetS-associated Dyslipidemia, as noted from biochemical results and histological examination.

A Comparative Study of the Triglycerides/HDL Ratio and Pseudocholinesterase Levels in Patients with Bladder Cancer. Diagnostics (Basel) 2022; 12:diagnostics12020431. [PMID: 35204522 PMCID: PMC8871224 DOI: 10.3390/diagnostics12020431] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 01/28/2022] [Accepted: 02/03/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Lipid alterations may serve as potential tumour biomarkers. The ratio of triglycerides to HDL cholesterol (TG/HDL ratio) is associated with various cancers. Pseudocholinesterase (PChE) activity, involved in TG hydrolysis, plays an important role in the metabolism of lipoprotein. There is scarce data assessing the reliability of both the TG/HDL ratio and PChE levels in correctly classifying patients suffering from bladder cancer. METHODS Three hundred and ninety-six patients undergoing cystoscopy or transurethral resection of the bladder (TURB), broken into two major groups, i.e., patients with histologically confirmed, non-metastatic bladder cancer (n = 208) and without bladder cancer (no bladder cancer, n = 188), formed the study population. The last group was split into two subgroups consisting of a cohort of patients never suffering from bladder cancer but with other bladder diseases (no CaBD, n = 100) and another cohort formed by patients characterised by eradicated bladder cancer after TURB with no recurrence during a three-month follow-up (previous bladder cancer, n = 88). Pieces of information by both metabolic derangement (the presence of type 2 diabetes mellitus), hypertension and lipid profile were retrieved from patient records upon entry to the study. Sensitivity, specificity, areas under the ROC (AUROC) of the TG/HDL ratio, and PChE levels were used in diagnostic decision making. RESULTS The TG/HDL ratio as well as PChE concentrations of bladder cancer patients were significantly different when compared to those with previous bladder cancer and the no CaBD patients (p = 0.023 and 0.0004, respectively). There was an independent role of both the TG/HDL ratio and PChE levels in predicting the presence of bladder cancer (OR: 1.22 and 0.99, respectively), but the reliability of the TG/HDL ratio (AUROC: 0.587) was superior to that of PChE levels (AUROC: 0.374). The AUROC of a new parameter resulting from the combination of the TG/HDL ratio with PChE levels showed a further increment in the discriminant power of the bladder cancer presence (0.6298), interestingly with a negative predictive value (89%) according to the Bayesian approach. The cut-off of the TG/HDL ratio, the main marker of the present study that better distinguishes bladder cancer from no bladder cancer patients, was 2.147. DISCUSSION AND CONCLUSIONS The reliability of the TG/HDL ratio is based on the fact that this parameter likely mirrors the insulin resistance (IR) underlying bladder cancer patients. Furthermore, PChE levels evidence both IR and the associated non-alcoholic fatty liver disease. The TG/HDL ratio and PChE levels as well as their combined use could help physicians to assess/confirm the presence of this very common cancer, where early detection is important to ensure the best therapeutical approach.

Effect of gestational diabetes mellitus on lipid profile: A systematic review and meta-analysis. Open Med (Wars) 2022; 17:70-86. [PMID: 34993347 PMCID: PMC8678474 DOI: 10.1515/med-2021-0408] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 11/12/2021] [Accepted: 11/15/2021] [Indexed: 01/10/2023] Open
Abstract
Gestational diabetes mellitus (GDM) can have adverse effects on pregnancy. GDM is associated with changes in the lipid profile of pregnant women. Finding out the early ways to diagnose GDM can prevent the adverse outcomes. This meta-analysis study aimed to determine the effect of GDM on lipid profile. PubMed, ProQuest, Web of Science, Scopus, Science Direct, Google Scholar, and ClinicalTrial were systematically searched for published articles relating to GDM until 2021 according to PRISMA guidelines. Newcastle Ottawa scale was used to assess the quality of the studies. Thirty-three studies with a sample size of 23,792 met the criteria for entering the meta-analysis. Pooled standardized mean difference (SMD) for total cholesterol (TC) and triglyceride (TG) was 0.23 mg/dL (95% CI: 0.11–0.34) and 1.14 mg/dL (95% CI: 0.91–1.38), respectively. The mean of TC and TG in people with GDM was higher than that in normal pregnant women. A similar pattern was observed for the very low-density lipoprotein (VLDL) and TG/high-density lipoprotein (HDL) ratio, with pooled SMD of 0.99 mg (95% CI: 0.71–1.27) and 0.65 mg (95% CI: 0.36–0.94), respectively. Pooled SMD for HDL was −0.35 mg/dL (95% CI: −0.54 to −0.16), women with GDM had a mean HDL lower than normal pregnant women. Although pooled SMD was higher for low-density lipoprotein (LDL) in the GDM group, this difference was not significant (0.14 [95% CI: −0.04 to 0.32]). Of all the lipid profiles, the largest difference between the GDM and control groups was observed in TG (SMD: 1.14). Elevated serum TG had the strongest effect on GDM. Higher levels of TC, LDL, VLDL, and TG/HDL ratio, and lower level of HDL were exhibited in GDM group. So, these markers can be considered as a reliable marker in the diagnosis of GDM.

TG/HDL Ratio: A marker for insulin resistance and atherosclerosis in prediabetics or not? J Family Med Prim Care 2021; 10:3700-3705. [PMID: 34934668 PMCID: PMC8653431 DOI: 10.4103/jfmpc.jfmpc_165_21] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 06/15/2021] [Accepted: 06/29/2021] [Indexed: 12/16/2022] Open
Abstract
Background: The spectrum of Diabetes Mellitus and various complications associated with it have been regarded as major global health challenges. Raised TG/HDL has been regarded as one of the valid markers for Insulin resistance. It leads to increased risk of CVD by causing Insulin resistance and also by its own effect on the vessel wall. Detection of raised TG/HDL ratio and early intervention before the patients develop clinical disease can help in mitigation of future consequences of CVD. Aims: The aim of our study was to compare TG/HDL ratio between prediabetics and controls and further to look for any correlation between the TG/HDL ratio value with HOMA-IR and Carotid Intima Media Thickness (CIMT) in prediabetics. Settings and Designs: A cross sectional study Methods and Material: Study was done at ABVIMS and Dr RML Hospital, New Delhi. 60 prediabetics and 60 age, sex, BMI matched controls were employed. In both cases and controls fasting and postprandial blood glucose, glycated Hemoglobin (HbA1C) and fasting Insulin levels were measured. HOMA-IR values in both the groups were calculated using fasting glucose and Insulin levels. Serum lipid profile was obtained and TG/HDL ratio was analysed in two groups. Values obtained were compared between the two groups. CIMT was only measured in cases using B mode ultrasonography. Statistical Analysis and Results: Median (IQR) of fasting plasma Insulin (μIU/ml) in cases was 11.3 (10.175-13.505) versus that in controls being 5.73 (4.3-7.1). HOMA-IR (IQR) values in cases and controls were 3.12 (2.73 - 3.595) and 1.21 (0.918 – 1.505) respectively. Median (IQR) for TG/HDL ratio was 3.26 (2.712 – 4) for cases and 2.05 (1.755- 2.502) for controls. However no correlation was observed between either the mean CIMT (mm) or HOMA-IR with TG/HDL ratio. Conclusions: Diabetes Mellitus and its various complications are of a great burden to society. Diagnosing the risk factors early before the onset of these manifestations can help us in combating these major issues. One of the risk factors among them is raised TG/HDL ratio. Early detection of elevated TG/HDL in prediabetics may serve in early detection of atherosclerotic complications and help physicians in framing primary preventive strategies for tackling ASCVD in patients with prediabetes and full-blown Diabetes.

Associations between TG/HDL ratio and insulin resistance in the US population: a cross-sectional study. Endocr Connect 2021; 10:1502-1512. [PMID: 34678755 PMCID: PMC8630769 DOI: 10.1530/ec-21-0414] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Accepted: 10/22/2021] [Indexed: 11/08/2022]
Abstract
BACKGROUND Clinical data on the relationship between triglycerides (TG)/HDL ratio and insulin resistance (IR) suggest that TG/HDL ratio may be a risk factor for IR. However, there is evidence that different races have different risk of developing IR. The relationship on TG/HDL ratio and IR in various populations needs to be improved. Therefore, we investigated whether TG/HDL ratio was linked to IR in different groups in the United States after controlling for other covariates. METHODS The current research was conducted in a cross-sectional manner. From 2009 to 2018, the National Health and Nutrition Examination Survey (NHANES) had a total of 49,696 participants, all of whom were Americans. The target-independent variable was TG/HDL ratio measured at baseline, and the dependent variable was IR. Additionally, the BMI, waist circumference, education, race, smoking, alcohol use, alanine transaminase, aspartate transaminase, and other covariates were also included in this analysis. RESULTS The average age of the 10,132 participants was 48.6 ± 18.4 years, and approximately 4936 (48.7%) were males. After correcting for confounders, fully adjusted logistic regression revealed that TG/HDL ratio was correlated with IR (odds ratio = 1.51, 95% CI 1.42-1.59). A nonlinear interaction between TG/HDL ratio and IR was discovered, with a point of 1.06. The impact sizes and CIs on the left and right sides of the inflection point were 6.28 (4.66-8.45) and 1.69 (1.45-1.97), respectively. According to subgroup analysis, the correlation was strong in females, alcohol users, and diabetes patients. Meanwhile, the inverse pattern was observed in the aged, obese, high-income, and smoking populations. CONCLUSION In the American population, the TG/HDL ratio is positively associated with IR in a nonlinear interaction pattern.

High triglyceride to HDL cholesterol ratio is associated with increased coronary heart disease among White but not Black adults. Am J Prev Cardiol 2021; 7:100198. [PMID: 34611638 PMCID: PMC8387296 DOI: 10.1016/j.ajpc.2021.100198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/03/2021] [Accepted: 05/15/2021] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE Black adults are less likely than White adults to present with adverse lipid profiles and more likely to present with low-grade inflammation. The impact of race on the association between atherogenic lipid profiles, inflammation, and coronary heart disease (CHD) is unknown. METHODS We evaluated the association between high levels (>50th percentile) of high-sensitivity C-reactive protein (hsCRP) and of triglycerides to high density lipoprotein ratio (TG/HDL-C) and CHD events by race in the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort with 30,239 Black and White participants aged 45 and older. RESULTS Participants with both high hsCRP and high TG/HDL-C had highest rates of CHD (HR 1.84; 95% CI: 1.48, 2.29 vs HR 1.52; 95% CI: 1.19, 1.94 in White vs Black participants respectively). Whereas isolated high hsCRP was associated with increased CHD risk in both races (HR 1.68; 95% CI: 1.31, 2.15 and HR 1.43; 95% CI: 1.13, 1.81 for White and Black participants respectively), isolated high TG/HDL was associated with increased CHD risk only in White participants (HR 1.44; 95% CI: 1.15, 1.79 vs HR 1.01; 95% CI: 0.74, 1.38). Further, the effects of high hsCRP and high TG/HDL-C were additive, with inflammation being the driving variable for the association in both races. CONCLUSION In both races, higher inflammation combined with adverse lipid profile is associated with greater CHD risk. Therefore, inflammation increases CHD risk in both races whereas dyslipidemia alone is associated with a greater risk in White but not in Black adults. hsCRP testing should be a standard feature of CHD risk assessment, particularly in Black patients.

Arterial Stiffness: Its Relation with Prediabetes and Metabolic Syndrome and Possible Pathogenesis. J Clin Med 2021; 10:jcm10153251. [PMID: 34362033 PMCID: PMC8348675 DOI: 10.3390/jcm10153251] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 07/01/2021] [Accepted: 07/21/2021] [Indexed: 11/26/2022] Open
Abstract
Aims: To evaluate arterial stiffness indicators in people with prediabetes (PreD) and its possible pathogenesis. Materials and methods: Pulse wave velocity (PWV) was measured in 208 people with FINDRISC ≥ 13 (57 ± 8 years old, 68.7% women) and thereafter divided into those having either normal glucose tolerance (NGT) or PreD. In each subgroup we also identified those with/out insulin resistance (IR) measured by the triglyceride/HDL-c ratio (normal cut off values previously established in our population). Clinical and metabolic data were collected for all participants. PWV was compared between subgroups using independent t test. Results: Women and men had comparable clinical and metabolic characteristics with obesity (BMI ≥ 30) and antihypertensive-statin treatment, almost half with either NGT or PreD. Whereas 48% of NGT people presented IR (abnormally high TG/HDL-c ratio), 52% had PreD. PWV was significantly higher only in those with a complete picture of metabolic syndrome (MS). Conclusions: Since PWV was significantly impaired in people with a complete picture of MS, clinicians must carefully search for early diagnosis of this condition and prescribe a healthy life-style to prevent development/progression of CVD. This proactive attitude would provide a cost-effective preventive strategy to avoid CVD’s negative impact on patients’ quality of life and on health systems due to their higher care costs.

Compared to serum triglyceride alone, the association between serum triglyceride to high-density lipoprotein cholesterol ratio and 10-year cardiovascular disease risk as determined by Framingham risk scores in a large Korean cohort. Clin Chim Acta 2021; 520:29-33. [PMID: 34058221 DOI: 10.1016/j.cca.2021.05.029] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 05/23/2021] [Accepted: 05/25/2021] [Indexed: 01/21/2023]
Abstract
BACKGROUND The incidence of cardiovascular disease (CVD) has gradually increased to the extent that it has become the most common cause of mortality worldwide, and triglyceride/high-density lipoprotein cholesterol (TG/HDL) ratio, a surrogate marker of insulin resistance, has emerged as an independent predictor of CVD. Additionally, several recent studies have reported an independent association between triglyceride-rich lipoproteins and CVD risk. The present study was conducted to investigate the association between the CVD risk determined by the Framingham risk score and the TG alone and TG/HDL ratio in a large Korean cohort. METHODS This cross-sectional study included 6,995 participants aged 30 to 69 years that participated in a health examination program. TG/HDL ratio quartiles and TG quartiles were categorized as follows: Q1: ≤ 1.25, Q2: 1.26-2.07, Q3: 2.08-3.48, and Q4: ≥3.49; Q1: ≤ 71, Q2: 72-105, Q3: 106-159, and Q4: ≥160, respectively. Odds ratios (ORs) and 95% confidence intervals (CI) for high Framingham 10-year CVD risk (≥10%) were calculated across TG/HDL ratio quartiles and TG quartiles using multiple logistic regression analysis after adjusting for confounding variables. RESULTS The mean values of most cardiometabolic variables including body mass index, blood pressure, fasting plasma glucose levels, leukocyte count, median CRP levels, and Framingham 10-year CVD risk scores increased gradually with TG/HDL ratio quartiles. The OR (95% CI) of the highest TG/HDL ratio quartile and TG quartile as compared with the lowest TG/HDL ratio quartile and TG quartile for high Framingham 10-year CVD risk was 9.27 (6.68-12.86) and 0.97 (0.69-1.36) after adjusting for confounding variables, respectively. CONCLUSION Compared to TG, the TG/HDL ratio was found to be positively and independently associated with Framingham 10-year CVD risk in a large Korean cohort.

Abstract
Abdominal obesity is defined as an accumulation visceral fat in abdomen region. It is linked to metabolic disorders that contribute to chronic diseases. Triglyceride (TG) to high-density lipoprotein (TG/HDL) ratio is considered as an insulin resistance (IR) marker. The waist to height ratio (WHtR) has been advocated as an effective and convenient measurement of central adiposity that could potentially be superior instead of BMI in determining cardiometabolic risk. The objective of this study was to investigate the effect of 8-wk-high protein diet and exercise on TG/HDL ratio, waist to height ratio (WHtR), body fat (BF) and body weight (BW). This study was a randomized clinical trial in 43 subjects with BMI >25 kg/m2. Subjects were randomized into 3 groups: High Protein Diet and Exercise (HPDE; n=15) High Protein Diet (HPD; n=15) and Control Group (CG; n=13). The prescribed diet consisted of 1,200 calories; while the exercise was conducted for 5 times/wk for 8 wk. The hypocaloric diet comprised of 55% carbohydrate, 25% protein, and 20% fat. In the end of the study, HPDE group had greater weight loss (-2.3±1.9 kg) than HPD (-1.8±2.2 kg); while CG increased in weight (1.8±1.3 kg). HPDE group had significantly improved TG, HDL, TG/HDL ratio and WHtR by -26.6 mg/dL, 12.7 mg/dL, -1.02, -0.02 respectively (p<0.05). There were significant differences between 3 groups, with ΔTG (p=0.008), ΔHDL (p=0.001), and ΔTG/HDL ratio (p=0.004) and WHtR (p=0.001). In conclusion, t hypocaloric diet combined with exercise has a beneficial effect in weight loss among young obese.

Associations of Triglycerides/High-Density Lipoprotein Cholesterol Ratio With Insulin Resistance, Impaired Glucose Tolerance, and Diabetes in American Adults at Different Vitamin D3 Levels. Front Endocrinol (Lausanne) 2021; 12:735736. [PMID: 35185778 PMCID: PMC8854269 DOI: 10.3389/fendo.2021.735736] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Accepted: 12/24/2021] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Previous studies have shown that vitamin D3 (VD3) may be a protective factor for diabetes mellitus (DM), while triglycerides/high-density lipoprotein (TG/HDL) may be a risk factor for diabetes. However, no existing study has elucidated the interaction between TG/HDL and VD3. Therefore, this work aimed to investigate the relationships of TG/HDL with insulin resistance (IR), impaired glucose tolerance (IGT), and DM at different VD3 levels. METHODS With the use of the data from five National Health and Nutrition Examination Survey (NHANES) cycles, a total of 2,929 males and 3,031 females were divided into 4 groups according to their VD3 levels. Logistic regression was performed to observe the associations of TG/HDL ratio with IR, IGT, and DM in different groups. RESULTS The relationships of TG/HDL with IR, IGT, and DM showed a threshold effect, with the cutoff values of 1.094, 1.51, and 1.11, respectively. On both sides of the cutoff values, the correlation was first weakened and then enhanced with the increase in VD3 levels. CONCLUSION TG/HDL is a risk factor for IR, IGT, and DM. Both too low and too high levels of VD3 can strengthen this association, whereas keeping VD3 at a reasonable level helps to reduce the associations of TG/HDL with IR, IGT, and DM.

Abstract
Objective: We investigated the association between the triglycerides to high-density lipoprotein cholesterol (TG/HDL) ratio and low testosterone and sex hormone-binding globulin (SHBG) levels in middle-aged and elderly men.Methods: This cross-sectional study included 1055 men aged ≥45 years who underwent a medical examination. The cutoff points for low testosterone and SHBG levels were determined as 12.2 and 29.4 nmol/L, which corresponded to the 25th percentile of the current sample. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for low testosterone and SHBG levels were calculated after adjusting for confounding variables across TG/HDL ratio quartiles (Q1: ≤ 1.70, Q2: 1.71-2.54, Q3: 2.55-3.77, Q4: ≥3.78) using multiple logistic regression analysis.Results: The proportion of subjects with low testosterone and SHBG levels significantly increased in accordance with TG/HDL ratio quartile. The ORs (95% CIs) of the lowest TG/HDL ratio quartile compared to the highest TG/HDL ratio quartile for low levels of testosterone and SHBG were 1.96 (1.13-2.75) and 3.90 (2.38-6.38), respectively, after adjusting for age, body mass index, smoking status, alcohol drinking, regular exercise, diastolic blood pressure, fasting plasma glucose, and total cholesterol level.Conclusions: The TG/HDL ratio was inversely associated with testosterone and SHBG levels in middle-aged and elderly Korean men.

The predictive value of red cell distribution width on erectile dysfunction. Andrologia 2019; 51:e13374. [PMID: 31347716 DOI: 10.1111/and.13374] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 05/27/2019] [Accepted: 06/06/2019] [Indexed: 01/27/2023] Open
Abstract
Red cell distribution width (RDW), one of the biomarkers used to measure vascular ageing, is known to correspond with cardiovascular diseases. As coronary artery disease and erectile dysfunction (ED) are both caused by the same shared pathophysiology, in this study, we compared the RDW values of men diagnosed with ED and those of healthy controls. Ninety-nine patients who were diagnosed with ED were included in the study. The control group consists of 100 men who presented to our outpatient clinic. Patients' fasting blood glucose, triglyceride, total cholesterol and LDL cholesterol levels were significantly higher in men diagnosed with ED. While the mean RDW value was 13.49 ± 1.52 in men with ED, it was 12.91 ± 1.13 in the control group. When RDW values were compared between the two groups, the RDW values of men with ED were found to be statistically significantly higher. Multivariate analyses showed that only the patients' body mass index, fasting blood sugar, triglyceride (TG), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol levels (HDL-C), TG/HDL-C ratio and RDW levels' relationship with ED was statistically significant. Although some studies have shown that RDW may be related to some diseases such as cardiovascular diseases and cancer, this appears to be the first study demonstrating a relationship between RDW and ED. RDW can be utilised as a predictor for the determination of the presence and monitoring of the severity of ED.

High triglyceride to high-density lipoprotein cholesterol ratio and arterial stiffness in postmenopausal Korean women. J Clin Hypertens (Greenwich) 2019; 21:399-404. [PMID: 30657241 DOI: 10.1111/jch.13484] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2018] [Revised: 11/16/2018] [Accepted: 12/09/2018] [Indexed: 12/14/2022]
Abstract
The ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL) is positively linked to insulin resistance, and it has emerged as an independent predictor of cardiovascular disease. Menopause is characterized by various detrimental metabolic and vascular changes that may lead to high TG with low HDL cholesterol and arterial stiffness. Several epidemiological studies have reported that high TG/HDL ratio has a positive association with arterial stiffness in both adult and adolescent populations; it is not known whether TG/HDL ratio is related to brachial-ankle PWV (baPWV) in postmenopausal women. Thus, the authors aimed to investigate the association between TG/HDL ratio and arterial stiffness as measured by baPWV in 434 postmenopausal women. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for high baPWV were calculated after adjusting for confounding variables across TG/HDL ratio quartiles using multiple logistic regression analysis. The mean values of meaningful cardiometabolic variables increased with TG/HDL ratio quartiles. The adjusted baPWV (SEs) significantly increased with TG/HDL quartiles: Q1 = 1412 (22.1), Q2 = 1469 (21.4), Q3 = 1482 (21.0), and Q4 = 1505 (21.6) cm/s after adjusting for age, body mass index (BMI), and systolic blood pressure. The OR (95% CI) of the highest TG/HDL ratio quartile as compared to the lowest TG/HDL ratio quartile for high PWV was 2.77 (1.16-6.63) after adjusting for age, BMI, smoking status, regular exercise, mean arterial pressure, fasting plasma glucose, total cholesterol level, hypertension, log-transformed C-reactive protein, and the use of antihypertensive and lipid-lowering drugs. The TG/HDL ratio was positively and independently associated with arterial stiffness in postmenopausal Korean women.

Abstract
Objectives: There is good evidence that shows that modification of modifiable risk factor will reduce the risk of stroke. Hyperlipidemia is one of these risk factors. Studies have shown that nontraditional serum lipid variables may be better predictors of vascular risk rather than others. The objective of the present study was to assess the relationships of traditional and nontraditional serum lipid measurements between young and elder patients with stroke and healthy young adults. Methods: One hundred twelve young patients with ischemic stroke, 113 healthy adults, and 110 patients with ischemic stroke aged >45 years were included in the study. Laboratory tests for total cholesterol (TC), its fractions, and triglycerides (TGs) were performed using standard techniques, and we computed four nontraditional lipid variables. Statistical analyses were performed using chi-square test, Student’s t-test, and SPSS version 16.0 software. A p value of <0.05 was considered statistically significant. Results: The mean age of 112 young patients with stroke was 38.46±5.96 years. There were 63 male and 49 female patients. Measurements of lipid parameters were as follows: low-density lipoprotein (LDL) 121.42±36.56 mg/dl, high-density lipoprotein (HDL) 38.84±12.47 mg/dl, TG 186.10±176.14 mg/dl, TC 194.76±45.35 mg/dl, LDL/HDL 3.39±1.46, TG/HDL 5.44±6.36, and TC/HDL 5.40±6.36. All lipid measurements were significantly higher in young patients with stroke than in healthy adults. The mean age of 110 patients with stroke aged >45 years was 69.53±12.34 years. There were 63 male and 47 female patients. Measurements of lipid parameters were as follows: LDL 125.18±35.97 mg/dl, HDL 41.47±14.16 mg/dl, TG 117.53±59.03 mg/dl, TC 190.16±42.96 mg/dl, LDL/HDL 3.32±1.55, TG/HDL 3.46±3.43, and TC/HDL 5.01±2.08. TG level and TG/HDL ratio were significantly higher in young patients with stroke than in older cases. Conclusion: All lipid measurements were significantly higher in young patients with ischemic stroke than in young healthy adults. TG level and TG/HDL ratio were significantly higher in male than in female patients. In addition, TG level and TG/HDL ratio were significantly higher in young patients with stroke than in older cases. As the TG/HDL ratio has proven to be a highly significant independent prognostic predictor of stroke, it should be calculated in young patients with ischemic stroke.

Abstract
OBJECTIVE To study prepregnancy serum lipid levels and the association with the number of children. DESIGN Prospective, population-based cohort. SETTING Linked data from the Cohort of Norway and the Medical Birth Registry of Norway. PARTICIPANTS 2645 women giving birth to their first child during 1994-2003 (488 one-child mothers and 2157 women with ≥2 births) and 1677 nulliparous women. MAIN OUTCOME MEASURES ORs for no and one lifetime pregnancy (relative to ≥2 pregnancies) obtained by multinomial logistic regression, adjusted for age at examination, education, body mass index (BMI), smoking, time since last meal and oral contraceptive use. RESULTS Assessed in quintiles, higher prepregnant triglyceride (TG) and TG to high-density lipoprotein (TG:HDL-c) ratio levels were associated with increased risk of one lifetime pregnancy compared with having ≥2 children. Compared with the highest quintile, women in the lowest quintile of HDL cholesterol levels had an increased risk of one lifetime pregnancy (OR 1.7, 95% CI 1.2 to 2.4), as were women with the highest low-density lipoprotein (LDL) cholesterol, TG and TG:HDL-c ratio quintiles (compared with the lowest) (OR 1.2, 95% CI 0.8 to 1.7; OR 2.2, 95% CI 1.5 to 3.2; and OR 2.2, 95% CI 1.5 to 3.2, respectively). Similar effects were found in women with BMI≥25 and the highest LDL and total cholesterol levels in risk of lifetime nulliparity. CONCLUSION Women with unfavourable prepregnant lipid profile had higher risk of having no or only one child. These findings substantiate an association between prepregnant serum lipid levels and number of children. Previously observed associations between low parity and increased cardiovascular mortality may in part be due to pre-existing cardiovascular disease lipid risk factors.

Abstract
BACKGROUND To determine whether TG/HDL-C ratio, which has been shown to be an indicator of the metabolic syndrome (MetS) and insulin resistance (IR), can predict cardiovascular risk factors in the Chinese Han population in Xinjiang. METHODS The cardiovascular risk survey (CRS) was conducted from October 2007 to March 2010. A total of 14,618 representative participants were selected using a four-stage stratified sampling method. A total of 5757 Han participants were included in the study. The present statistical analysis was restricted to the 5595 Han subjects who had complete anthropometric data. The sensitivity, specificity, and distance on the receiver operating characteristic (ROC) curve in each TG/HDL level were calculated. The shortest distance in the ROC curves was used to determine the optimal cutoff of the TG/HDL-C ratio for detecting cardiovascular risk factors. RESULTS The prevalence of hypertension, hypercholesterolemia, and hypertriglyceridemia was higher with higher TG/HDL-C ratio for both men and women. The TG/HDL-C ratio was positively associated with systolic blood pressure, diastolic blood pressure, and serum concentrations of total cholesterol. The optimal TG/HDL-C ratio cutoffs for predicting hypertension, dyslipidemia, diabetes, and ≥2 of these risk factors for Han adults in Xinjiang were 1.3, 1.3, 1.4, and 1.4 in men and 0.9, 1.0, 1.0, and 1.1 in women, respectively. CONCLUSIONS The evaluation of TG/HDL-C ratio should be considered for one of cardiovascular risk factor predictors among Han adults in Xinjiang.

Abstract
Chronic disease is driven by inflammation. This article will provide an overview on how the balance of macronutrients and omega-6 and omega-3 fatty acids in the diet can alter the expression of inflammatory genes. In particular, how the balance of the protein to glycemic load of a meal can alter the generation of insulin and glucagon and the how the balance of omega-6 and omega-3 fatty acids can effect eicosanoid formation. Clinical results on the reduction of inflammation following anti-inflammatory diets are discussed as well as the molecular targets of anti-inflammatory nutrition. To overcome silent inflammation requires an anti-inflammatory diet (with omega-3s and polyphenols, in particular those of Maqui). The most important aspect of such an anti-inflammatory diet is the stabilization of insulin and reduced intake of omega-6 fatty acids. The ultimate treatment lies in reestablishing hormonal and genetic balance to generate satiety instead of constant hunger. Anti-inflammatory nutrition, balanced 40:30:30 with caloric restriction, should be considered as a form of gene silencing technology, in particular the silencing of the genes involved in the generation of silent inflammation. To this anti-inflammatory diet foundation supplemental omega-3 fatty acids at the level of 2-3 g of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) per day should be added. Finally, a diet rich in colorful, nonstarchy vegetables would contribute adequate amounts of polyphenols to help not only to inhibit nuclear factor (NF)-κB (primary molecular target of inflammation) but also activate AMP kinase. Understanding the impact of an anti-inflammatory diet on silent inflammation can elevate the diet from simply a source of calories to being on the cutting edge of gene-silencing technology.

Abstract
BACKGROUND Triglycerides (TG) to high-density lipoprotein cholesterol (HDL-C) ratio (TG/HDL-C) has been recommended for surrogates of insulin resistance. However, it remains to be elucidated the association between TG/HDL-C and incident fatty liver. AIMS To investigate the association between TG/HDL-C and incident fatty liver. METHODS We performed population-based historical cohort study consisted with 4518 healthy Japanese who received yearly health-checkup programmes over decade. Fatty liver was diagnosed using ultrasonography. RESULTS During the observation periods, 38.8% (case/N = 1023/2637) of men and 17.2% (case/N = 324/1881) of women developed fatty liver. Adjusting odds ratio of TG/HDL-C for incident fatty liver were 1.59 (95% confidence interval (CI) 1.42-1.79, P < 0.0001) in men and 2.50 (95% CI 1.80-3.51, P < 0.0001) in women. In addition, adjusting odds ratio of TG/HDL-C for incident non-alcoholic fatty liver disease were 1.55 (95% CI 1.35-1.77, P < 0.0001) in men and 2.72 (95% CI 1.88-3.95, P < 0.0001) in women. According to the receiver operator characteristic (ROC) analysis, the optimal cut-off point of TG/HDL-C for incident fatty liver was 0.88 (area under the ROC curve (AUC) 0.67 [95% CI 0.65-0.69], sensitivity = 0.64, specificity = 0.60, P < 0.0001) in men and 0.64 (AUC 0.69 [95% CI 0.66-0.72], sensitivity = 0.50, specificity = 0.78, P < 0.0001) in women. CONCLUSIONS The TG/HDL-C could predict the incident fatty liver. Thus, it is important to check TG/HDL-C and lifestyles modification is needed for preventing future fatty liver disease in patients with high TG/HDL-C.
