Association of lipid accumulation product with all-cause and cardiovascular disease mortality: Result from NHANES database

Background and aimAt present, there are few studies on the relationship between lipid accumulation product (LAP) and mortality. This study aims to explore the relationship between adult LAP and all-cause and cardiovascular disease (CVD) mortality. Methods and resultsThe study people from the National Health and Nutrition Examination Survey (NHANES). Results of the mortality study were based on death data up to December 31, 2019. Cox proportional risk model was used to estimate the risk ratio (HR) and 95 % CI of all-cause and CVD mortality. A total of 50162 people were included in the study (the weighted average age and male proportion were 48.14 years and 48.64 % respectively). During the follow-up of 203460871 person-years, 6850 deaths were recorded, including 1757 CVD deaths. After multivariable adjustment, the increase of LAP was significantly correlated with all-cause and CVD mortality. Compared with the participants of Quartile 1 of LAP, the multivariable adjusted HRs and 95 % CI of the participants of Quartile 4 of LAP were 1.54 (1.32, 1.80) all-cause mortality (P for trend<0.001), and 1.55 (1.16, 2.09) CVD mortality (P for trend = 0.04). For every increase of natural log-transformed LAP, the all-cause mortality increased by 22 %, and the CVD mortality increased by 14 % (both P < 0.05). ConclusionsOur cohort study based on NHANES showed that higher LAP was significantly associated with higher all-cause and CVD mortality. Maintaining a low LAP status may reduce the risk of death.

Associations of lipid accumulation product, visceral adiposity index, and triglyceride-glucose index with subclinical organ damage in healthy Chinese adults.

Obesity is an independent risk factor for cardiovascular disease development. Here, we aimed to examine and compare the predictive values of three novel obesity indices, lipid accumulation product (LAP), visceral adiposity index (VAI), and triglyceride-glucose (TyG) index, for cardiovascular subclinical organ damage. A total of 1,773 healthy individuals from the Hanzhong Adolescent Hypertension Study cohort were enrolled. Anthropometric, biochemical, urinary albumin-to-creatinine ratio (uACR), brachial-ankle pulse wave velocity (baPWV), and Cornell voltage-duration product data were collected. Furthermore, the potential risk factors for subclinical organ damage were investigated, with particular emphasis on examining the predictive value of the LAP, VAI, and TyG index for detecting subclinical organ damage. LAP, VAI, and TyG index exhibited a significant positive association with baPWV and uACR. However, only LAP and VAI were found to have a positive correlation with Cornell product. While the three indices did not show an association with electrocardiographic left ventricular hypertrophy, higher values of LAP and TyG index were significantly associated with an increased risk of arterial stiffness and albuminuria. Furthermore, after dividing the population into quartiles, the fourth quartiles of LAP and TyG index showed a significant association with arterial stiffness and albuminuria when compared with the first quartiles, in both unadjusted and fully adjusted models. Additionally, the concordance index (C-index) values for LAP, VAI, and TyG index were reasonably high for arterial stiffness (0.856, 0.856, and 0.857, respectively) and albuminuria (0.739, 0.737, and 0.746, respectively). Lastly, the analyses of continuous net reclassification improvement (NRI) and integrated discrimination improvement (IDI) demonstrated that the TyG index exhibited significantly higher predictive values for arterial stiffness and albuminuria compared with LAP and VAI. LAP, VAI, and, especially, TyG index demonstrated utility in screening cardiovascular subclinical organ damage among Chinese adults in this community-based sample. These indices have the potential to function as markers for early detection of cardiovascular disease in otherwise healthy individuals.

Association of lipid accumulation product and visceral adiposity index with the risk of hypertension among oil workers in Xinjiang, China.

To explore the relationship between lipid accumulation product (LAP) and visceral adiposity index (VAI) and hypertension in oil workers and to evaluate the predictive value of hypertension by gender. A sample of 2,312 workers aged 18-60 years old with more than one year of service were selected by a whole-group random sampling method in six oil field bases in Karamay City, Xinjiang. Logistic regression combined with restricted cubic spline model was used to analyze the risk of hypertension in different LAP and VAI. The receiver operator characteristic curve (ROC) with different sex LAP and VAI predicting the risk of hypertension were drawn. (1) There were significant differences in age, smoking, alcohol consumption, hypertension, BMI, WC, WHtR, SBP, DBP, TC, TG, HDL, LDL, FPG and Scr among different gender groups (P < 0.001).The prevalence of hypertension was 10.1%, with 13.9% in men and 3.6% in women. The prevalence of hypertension with different individual characteristics was statistically significant (P < 0.05). (2) Lipid accumulation product and visceral adiposity index were positively associated with hypertension (P < 0.001). The risk of hypertension may increase with the increase of lipid accumulation product and visceral adiposity index. After adjusting for age, sex, BMI, Scr, FPG and other factors, the risk of hypertension in the fourth quartile was (OR = 5.69, 95% CI [2.72-11.8]) and (OR = 3.56, 95% CI [2.03-6.23]) compared with the first quartile of lipid accumulation product and visceral adiposity index. (3) ROC results showed: AUC values of 0.658 (95% CI [0.619-0.696]), 0.614 (95% CI [0.574-0.654]), 0.661 (95% CI [0.620-0.703]) and critical values of 43.25, 1.58, 0.13 for LAP, VAI and combined indicators in men; the AUC values of LAP, VAI and combined indicators for women were 0.787 (95% CI [0.710-0.865]), 0.732 (95% CI [0.640-0.825]), 0.792 (95% CI [0.719-0.864]) and the critical values were 35.73, 1.76 and 0.03. Restricted cubic splines showed a nonlinear dose-response relationship between LAP, VAI, and risk of hypertension prevalence (P < 0.01 for overall trend and P < 0.01 for nonlinearity). Lipid accumulation product and visceral adiposity index may be risk factors for hypertension in oil workers. LAP and VAI have certain predictive value for hypertension.

Association of Lipid Accumulation Product with Insulin Resistance in Type 2 Diabetes Mellitus: A Cross-sectional Study

Introduction: The increased incidence of diabetes and Cardiovascular Disease (CVD) is attributed to the rising obesity rates, which is one of the major factors contributing to Insulin Resistance (IR). Although there is a close relationship between obesity and IR, not all cases of obesity lead to cardiometabolic complications. Visceral fat is considered to be the primary cause of IR. Lipid Accumulation Product (LAP) is postulated as a new continuous biomarker of visceral adiposity. Aim: To determine the association between LAP and IR in T2DM. Materials and Methods: This institution-based cross-sectional study was conducted over a period of three months at the Department of Biochemistry, Rajarajeswari Medical College and Hospital in Bengaluru, Karnataka, India. A total of 60 Type 2 diabetic patients (including newly diagnosed and known cases) were recruited as cases, along with 30 healthy controls. Height, weight, and Waist Circumference (WC) were measured. Fasting blood samples were collected for laboratory biochemical estimation of glucose, Total Cholesterol (TC), Triglycerides (TG), High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), and fasting insulin. Statistical analysis for continuous variables was performed using unpaired Student’s t-test, and Analysis of Variance (ANOVA) test was used for group comparisons. Results: Fasting serum insulin (p-value=0.007), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) (p-value=0.001), and LAP index (p-value&lt;0.001) were significantly higher in the case group. LAP index was divided into quartiles, Insulin and HOMA-IR showed statistical significance across the quartiles (p-value=0.005). The lipid profile analysis across LAP quartiles revealed a progressive increase in TG levels (p&lt;0.001) and a decrease in HDL levels from Q1 to Q4 quartiles. Conclusion: The study concludes that increased LAP levels are associated with IR in T2DM. LAP can serve as a useful marker for cardiometabolic risk in early-stage T2DM, enabling better disease stratification for improved prognosis.

Association of Lipid Accumulation Product With Insulin Resistance and Metabolic Syndrome in Type 2 Diabetic Patients In Relation With Dietary Habit in Bangladeshi Population

Background: Lipid accumulation product (LAP) is a novel biomarker of central lipid accumulation related to diabetes and cardiovascular disease risk. In this study, we assessed the association of LAP with glucose homeostasis, lipid profile parameters, and some clinical parameters about fast food-taking habits of diabetic patients. This study evaluated the relationship between lipid accumulating product (LAP) with insulin resistance and metabolic syndromeinfast food-taking patterns in the Bangladeshi type 2 diabetic population. Methods: Three hundred and seventy-five T2DM subjects as cases and three hundred and seventy-five healthyindividuals as control were assessed for anthropometric and biochemical measurements. LAP was calculated as [waist circumference (cm)–65]×[triglycerides (mmol/L)] in men, and [waist circumference (cm)–58]×[triglycerides (mmol/L)] in women. Associations of LAP with fasting glucose, insulin, insulin resistance index, and lipid profile levels, were assessed. Fast food-taking habits per week were also taken from the study subjects. Some clinical parameters (BMI, blood pressure, and waist-hip ratio) were also measured. Results: LAP was significantly correlated with glycemic markers like FBG, ABF,F. Insulin,HBA1C, HOMA-IR, HOMA B%, and Serc-HOMA in type-2 DM subjects. The p-value was less than 0.001. This study was alsosignificantly (p=&lt;0.001) correlated with lipidemic markerslike TAG &amp;LAP in type-2 DM subjects.LAP was significantly associated with BMI, waist-hip ratio (WHR), SBP, and DBP in T2DM subjects. Multiple comparisons of LAP with fast food-taking habits in the study population showed that mean LAP was significantly (p&lt;0.02) higher in the positive fast food-taking habit-containing study group. Conclusion: LAP was significantly correlated with insulin resistance and metabolic syndrome in T2 diabetic subjects.The favorable, fast food-eating habit-containing study group had considerably greater LAP.

Association of lipid accumulation product with type 2 diabetes mellitus, hypertension, and mortality: a systematic review and meta-analysis.

Novel anthropometric measures are simple, applicable, and inexpensive tools for cardiovascular risk assessment. This study evaluates the association of lipid accumulation product (LAP) with hypertension, type 2 diabetes mellitus (T2DM), and all-cause mortality, and compares it with other anthropometric measures. PubMed, Web of Science, EMBASE, and Scopus were systematically searched for articles published until May 15, 2021. We included all the studies that had measured LAP predictability for T2DM, all-cause mortality, and hypertension with no limitation in comorbidities and follow-up duration. We assessed the predictability measures of LAP for the aforementioned outcomes. We also performed a meta-analysis on four articles on mortality using an inverse variance method by the "meta" package in R software. Twenty-nine studies were included in the review after applying the eligibility criteria. The hazard ratio for all-cause mortality per one standard deviation increment of LAP was 1.24 (95% confidence interval [CI]: 1.00-1.53; P = 0.0463) in females, and 1.07 (95% CI: 0.74-1.57; P = 0.709) in males. All included studies found a direct association between LAP with T2DM and hypertension. However, studies used different cut-off points for LAP. Most studies found that LAP was superior in predicting T2DM and hypertension compared to conventional indices, e.g., body mass index and waist circumference. We found that LAP may have higher prognostic significance in females compared to males. LAP is an inexpensive method to evaluate the risk of all-cause mortality, T2DM, and hypertension, and could outperform conventional anthropometric indices in this regard.

Relationship between lipid accumulation product and oxidative biomarkers by gender in adults from Yucatan, Mexico

Excessive adipose tissue can lead to metabolic abnormalities resulting in lipid alteration and oxidative stress (OS) status. The lipid accumulation product (LAP) index is a biomarker that indicates central lipid accumulation and has been proposed as an accurate and independent indicator of risk for several cardiometabolic related conditions. There is a lack of information about the possible association of LAP and OS biomarkers. Therefore, this work aimed to investigate the relationship between LAP and OS biomarkers in adults. A cross-sectional study was performed in 250 subjects attending the Hospital Regional de Alta Especialidad de la Península de Yucatán. Anthropometrical and clinical parameters were measured. The serum oxidative biomarkers such as malondialdehyde (MDA) and total antioxidant capacity (TAC) were evaluated by spectrophotometry and by the oxygen radical absorbance capacity (ORAC), respectively. A positive and significant correlation between serum levels of MDA and LAP (r = 0.162, p = 0.010) was observed. This relationship was stronger in women (r = 0.189, p = 0.013) than in men. The association between them remained significant after adjusting for confounders (r = 0.23, p < 0.001). A cutoff of LAP of 73.73 predicts high levels of MDA in women aged between 40 and 59. LAP index was associated with OS biomarkers in women and men from Yucatan, Mexico. Therefore, the elevation of the LAP index could identify an imbalance in the redox status.

Association of Lipid Accumulation Product and Triglyceride-Glucose Index with Metabolic Syndrome in Young Adults: A Cross-sectional Study.

BackgroundMetabolic syndrome is a cluster of elements linked with type 2 diabetes mellitus and cardiovascular disease (CVD). The early detection of individuals at the risk of developing metabolic syndrome can prevent the development of type 2 diabetes mellitus and CVD.ObjectivesThis study aimed to evaluate the association of the lipid accumulation product (LAP) and triglyceride-glucose (TyG) index with metabolic syndrome among young adults.MethodsThis cross-sectional study included 300 young adults within the age range of 20 - 40 years. Metabolic syndrome was defined according to modified National Cholesterol Education Program Adult Treatment Panel III guidelines. The LAP and TyG index were calculated. Multivariate logistic regression and receiver operating characteristic curve analyses were performed to assess the association of the LAP and TyG index with metabolic syndrome.ResultsThe LAP and TyG index were significantly associated with metabolic syndrome (P < 0.05). The LAP showed the highest area under the curve (0.882 and 0.905 in male and female subjects, respectively), followed by the TyG index (0.875 and 0.886 in male and female subjects, respectively, at P < 0.0001. The cut-off values for the LAP were 45.65 in males with a sensitivity and specificity of 80% and 46.91 in females with a sensitivity and specificity of 88%. The cut-off points for the TyG index were 8.63 in males with 80% sensitivity and 78.9% specificity and 8.54 in females with 83.3% sensitivity and 79.6% specificity.ConclusionsThe LAP and TyG index are significantly associated with metabolic syndrome in young adults. As simple and inexpensive markers, they can be used to identify individuals with metabolic syndrome with high sensitivity and specificity.

Association of lipid accumulation product with chronic kidney disease in Chinese community adults: a report from the REACTION study

BackgroundLimited studies regarding the correlation of lipid accumulation product (LAP) with a decreased estimated glomerular filtration rate (eGFR) have yielded conflicting findings, and no report has demonstrated the relationship of LAP with chronic kidney disease (CKD), defined as the presence of albuminuria and/or a decreased eGFR. The purpose of this study was to estimate the possible correlation of LAP with CKD prevalence in Chinese community adults.MethodIn this cross-sectional study, LAP level of 7202 participants (age ≥ 40 years) was determined, and its possible association with CKD was evaluated by a multiple logistic regression model.ResultsCompared with subjects with non-CKD, non-albuminuria, and high eGFR, LAP levels significantly increased in female not male subjects with CKD, albuminuria, and low eGFR, respectively (all P < 0.001). The univariate logistic regression analysis revealed that LAP level of female not male subjects were significantly and positively associated with the prevalence of CKD (P < 0.001). The multivariate logistic regression analysis showed that the risk of CKD prevalence in female not male subjects progressively increased across LAP quartiles (P for trend < 0.01), and the risk of CKD prevalence of subjects in Q4 significantly increased compared to those in Q1 after adjustment for potential confounding factors in Models 4 (odds ratio [OR]: 1.382, 95% confidence intervals [CI] 1.002–1.906, P < 0.05). Stratified analysis revealed positive associations of LAP quartiles with risk of CKD prevalence in people with the following characteristics: women, older, overweight, with hypertension, normal glucose tolerance, appropriate low-density lipoprotein cholesterol, nonsmokers, nondrinkers, and no cardiovascular disease events.ConclusionsHigh LAP levels might be significantly associated with risk of CKD prevalence in community-dwelling Chinese female adults, which may inform both public health recommendations and clinical practice.

Association of lipid accumulation product with Gestational Diabetes Mellitus: a hospital based study

Background: Gestational Diabetes Mellitus (GDM) is an emerging problem which affects a large number of pregnant women in India. Women with GDM have been shown to have abnormal lipid profiles with higher serum triacylglycerol concentrations but lower LDL levels. Early detection reduces adverse maternal and foetal outcome. The Lipid Accumulation Product (LAP) is an index of fat distribution and assessment which can be easily measured in an outpatient setup. Methods: This study was a hospital based case control study. Cases were 30 pregnant women, newly diagnosed with GDM in their 2nd trimester while controls were 30 apparently healthy pregnant women without risk factors for GDM. Lipid accumulation product (LAP) was computed by multiplying a sex-specific estimate of waist circumference and the fasting triglyceride concentration, LAP = (WC [cm] - 58) x TGL [mmol/L]. Result: The mean age of patients with GDM was higher when compared to controls. (28.17 ± 3.34 vs 24.40 ± 3.07, p < 0.0001) The lipid profile showed a significantly higher value of serum triglycerides among cases while the differences in HDL were not statistically significant. Lipid accumulation product (LAP) in GDM patients was found to be significantly elevated when compared to controls. (133.43 ± 64.02 vs 62.89 ± 30.68, p < 0.0001) Conclusion: Calculation of LAP can be done to identify the degree of risk for developing GDM. So LAP can possibly serve as in future as a screening tool for the diagnosis of GDM in an outpatient setting in resource poor settings. DOI: 10.21276/AWCH.1461

Abstract P109: Lipid Accumulation Product (LAP) is Associated with Hepatic Steatosis Among Individuals without Metabolic Syndrome

Background: The Lipid accumulation product (LAP) is a simple index formulated to identify cardiometabolic disorders. It has been shown to be predictive of the metabolic syndrome (MS) and its associated risk. Hepatic steatosis (HS) is associated with cardiometabolic disorders and considered an independent risk factor for increased cardiovascular disease (CVD). We evaluated the association of LAP with HS is the presence and absence of MS in an asymptomatic population. Methods: We evaluated 6,464 asymptomatic Brazilian subjects (43±10 years, 79% males) between November 2008 and July 2010. LAP (waist-58 х triglycerides [nmol/L]) was divided into quartiles and HS was defined by abdominal sonogram. Results: The overall prevalence of HS was 36% (n=2,310). There was a steady increase in HS prevalence with LAP quartiles: Q1- 3%, Q2- 14%, Q3- 31%, Q4- 52, p&lt;0.001. Twenty percent had MS, 75% of whom were in the 4 th quartile of LAP. In a logistic regression analysis higher quartiles of LAP were independently associated with higher prevalent odds of HS. When stratified by the presence of MS, the association only remained significant among persons without MS. See Table below. Conclusions: In an asymptomatic population there is an association between the higher LAP index and Hepatic Steatosis in persons without the metabolic syndrome. LAP index may be a relevant tool in predicting and screening for HS in individuals without MS.

Comparison of lipid accumulation product with body mass index as an indicator of hypertension risk among Mongolians in China

To compare associations of lipid accumulation product (LAP) and body mass index (BMI) with risk of hypertension. Demographic characteristics, blood pressure and body measurements were obtained, blood lipids and fast plasma glucose were examined, BMI and LAP were calculated for 2589 Mongolians. Multiple linear model and covariance analysis was used to analyze the relationship between LAP and blood pressure levels, multivariate logistic analysis was used to analyze the association between BMI and LAP and hypertension. LAP and BMI were all significantly higher in hypertensives than in normotensives in both genders. Multivariate adjusted mean levels of SBP and DBP increased with increased LAP and there was a linear association between LAP and blood pressure. LAP had a stronger association with risk of hypertension compared with BMI, linear trend between LAP and risks of hypertension was better than that between BMI and risks of hypertension in males. Compared to the first quartile, the odds ratios [95% confidence intervals (95% CIs)] of hypertension associated with the second, third and fourth quartiles of LAP were 1.85(1.23,2.79), 2.20(1.47,3.28), 4.21(2.78,6.38) in males; compared to the first quartile, the odds ratios (95% CIs) of hypertension associated with the second, third and fourth quartiles of BMI were 0.93(0.62,1.38), 1.23(0.83,1.84), 2.80(1.86,4.21) in males. LAP was more closely associated with risk of hypertension than BMI in Mongolian males, this study suggested that LAP might be a preferred anthropometry measurement to predict risk of hypertension in males. Future prospective cohort studies should be conducted to test the causal relationship between LAP and the risk of hypertension in Mongolian population.
