ABSTRACT

Fundamento: Las alteraciones del estado nutricional materno generalmente se relacionan con desviaciones del crecimiento fetal, que pueden detectarse por los parámetros biofísicos fetales e identifican la posible condición trófica al nacer. Objetivo: Determinar la posible relación entre los parámetros biométricos fetales, la condición trófica al nacer y el producto de acumulación de los lípidos. Metodología: Se realizó un estudio transversal en el Policlínico Chiqui Gómez Lubian del municipio Santa Clara, durante el año 2019, en una población de 253 gestantes normopeso supuestamente sanas al inicio de la gestación. La muestra no probabilística fue de 144 gestantes. Las variables de estudio fueron: producto de acumulación de los lípidos, biometría fetal y condición trófica al nacer. Se utilizaron métodos teóricos, empíricos y estadísticos. Resultados: En el segundo trimestre ningún parámetro biométrico coincidió con la condición al nacer de pequeño, mientras que para el grande coincidieron las circunferencias cefálica y abdominal. En el tercer trimestre la longitud del fémur y la circunferencia abdominal coinciden en la identificación del pequeño y del grande. El PAL se correlacionó con la circunferencia abdominal del tercer trimestre y con el peso al nacer; presentando mayor frecuencia de valores en el tercer tertil para los nacimientos grandes. Conclusiones: La circunferencia abdominal fue el parámetro biométrico con mayor coincidencia con la condición trófica al nacer, la que se asoció con valores en el tercer tertil del PAL para la detección de nacimientos grandes, relacionándose el fenotipo normopeso metabólicamente obeso con el crecimiento fetal por exceso.


Background: Maternal nutritional status disorders are usually related to fetal growth deviations, which can be detected by fetal biophysical parameters and identify the possible trophic condition at birth. Objective: To determine the possible relationship between fetal biometric parameters, the birth trophic state and lipid accumulation product. Methodology: A cross-sectional study was conducted at the Chiqui Gómez Lubian Polyclinic in Santa Clara municipality, during 2019, in a population of 253 normal-weight pregnant women who were apparently healthy at the beginning of their gestation. The non-probability sample was made up of 144 pregnant women. Study variables were: lipid accumulation product, fetal biometry and trophic condition at birth. Theoretical, empirical and statistical methods were used. Results: In the second trimester, none of the biometric parameters matched the condition at birth as a small child, while in the large one the head and abdominal circumferences matched. In the third trimester, femoral length and abdominal circumference coincide in identifying the small one and the large one. LAP correlated with third trimester abdominal circumference and birth weight, presenting higher frequency of values in the third tertile for large births. Conclusions: Abdominal circumference was the biometric parameter with the highest coincidence with trophic condition at birth, associated with values in the third tertile of the LAP for detecting large births, relating the metabolically obese normal weight phenotype with excessive fetal growth.

ABSTRACT

Objective To explore the association of (cardiometabolic index , CMI ) and ( lipid accumulation product , LAP ) with the prevalence of hypertension in adults in Pingshan District, Shenzhen, and to evaluate the predictive value of CMI and LAP for the prevalence of hypertension. Methods A cross-sectional survey was conducted, in which 1000 permanent residents aged 18-69 years in Pingshan District, Shenzhen were randomly selected as survey subjects. The data were collected using questionnaires, physical measurements and blood tests, and the relationship between CMI, LAP and hypertension prevalence was analyzed using logistic regression models. Results A total of 987 subjects were included in the analysis, including 471 (47.72%) males and 516 (52.28%) females, with an average age of 40.9 ± 11.1 years. Subjects of different genders were divided into groups Q1 to Q4 according to quartiles of CMI and LAP, and the prevalence of hypertension increased with increasing levels of CMI and LAP in both men and women (P for trend < 0.001). Logistic regression analysis revealed that after adjusting for variables such as age and occupation, the OR for hypertension was 1.251 (1.025-1.526) and 1.685 (1.001-2.836) for men and women, respectively, for each standard deviation increase in CMI; the OR for hypertension was 3.519 (1.343-9.222) for men in the Q4 group, compared to the CMI subgroup Q1. For each standard deviation increase in LAP, the ORs for hypertension were 1.355 (1.089-1.686) and 1.825 (1.023-3.254) for men and women, respectively; compared to LAP subgroup Q1, the ORs for hypertension in the male Q3 and Q4 groups were 2.554 (1.103-5.909) and 5.322 (2.393-11.834), while the OR for hypertension in the female Q4 group was 2.906 (1.096-7.703). ROC analysis revealed that the area under the curve (AUC) for CMI, LAP, and BMI was 0.671, 0.704, and 0.702 for males, and 0.660, 0.722, and 0.697 for females, respectively. The AUC for LAP was greater than that for CMI for different genders (P < 0.01). Conclusion The greater the CMI and LAP values in adults in Pingshan District, Shenzhen , the higher the prevalence of hypertension. CMI and LAP have certain values in predicting the prevalence of hypertension.

ABSTRACT

Introducción: Son escasos los estudios sobre acumulaciones excesivas de tejido adiposo y su asociación con cambios en indicadores bioquímicos estudiados durante el embarazo y el posparto. Objetivo: Determinar asociaciones de la vulnerabilidad cardiometabólica por adiposidad corporal con indicadores bioquímicos en el momento de la captación de la embarazada y el posparto. Métodos: Se realizó estudio observacional prospectivo de la vulnerabilidad cardiometabólica por adiposidad corporal e indicadores bioquímicos en 773 mujeres captadas como sanas de peso adecuado, de ellas 119 al posparto, en el policlínico Chiqui Gómez Lubián. Se estudiaron por grupo de vulnerabilidad cardiometabólica indicadores bioquímicos a la captación y el posparto. Se aplicó prueba estadística de Kruskal-Wallis. Resultados: Gestantes captadas con vulnerabilidad global por adiposidad general intermedia y central alta tuvieron valores medios más bajos del ácido úrico (238,78 mmol/L), más altos de triglicéridos (1,37 mmol/L), colesterol (4,70 mmol/L) y resistencia a la insulina (8,32). Mujeres con vulnerabilidad global por adiposidad general intermedia y central alta al posparto presentaron valores medios más elevados de triglicéridos (1,18 mmol/L) y lipoproteínas de muy baja densidad (0,54 mmol/L), más bajos de lipoproteínas de alta densidad (1,06 mmol/L); mujeres con vulnerabilidad global extrema por adiposidad general y central alta, tuvieron valores medios más elevados: glicemia (4,90 mmol/L), colesterol (4,30 mmol/L), lipoproteínas de baja densidad (2,76 mmol/L), producto de acumulación de lípidos (42,63 mmol/L) e índice de adiposidad visceral (2,32 mmol/L). Conclusiones: Evaluar vulnerabilidad cardiometabólica por técnicas antropométricas, complementadas con indicadores bioquímicos, facilita orientar acciones preventivas sobre daños cardiometabólicos progresivos en la gestación y su posparto(AU)


Introduction: Few studies are available about excessive accumulation of adipose tissue and its association to changes in biochemical indicators in pregnancy and the postpartum period. Objective: Determine the association between cardiometabolic vulnerability due to body adiposity and biochemical indicators during recruitment of pregnant women and in the postpartum period. Methods: An observational prospective study was conducted of cardiometabolic vulnerability due to body adiposity and biochemical indicators in 773 women recruited as healthy and adequate weight, 119 of them in the postpartum period, at Chiqui Gómez Lubián polyclinic. Biochemical indicators were studied by cardiometabolic vulnerability group at recruitment and in the postpartum period. Statistical analysis was based on the Kruskal-Wallis test. Results: Pregnant women recruited with overall vulnerability due to high general intermediate and central adiposity had lower uric acid mean values (238.78 mmol/l), higher triglyceride mean values (1.37 mmol/l), cholesterol (4.70 mmol/l) and insulin resistance (8.32). Women with overall vulnerability due to high general intermediate and central adiposity in the postpartum period had higher triglyceride mean values (1.18 mmol/l), very low density lipoproteins (0.54 mmol/l), and lower high density lipoprotein mean values (1.06 mmol/l). Women with extreme overall vulnerability due to high general and central adiposity had higher mean values: glycemia (4.90 mmol/l), cholesterol (4.30 mmol/l), low density lipoproteins (2.76 mmol/l), lipid accumulation product (42.63 mmol/l) and visceral adiposity index (2.32 mmol/l). Conclusions: Evaluating cardiometabolic vulnerability using anthropometric techniques complemented with biochemical indicators, facilitates aiming preventive actions at progressive cardiometabolic damage during pregnancy and the postpartum period(AU)

ABSTRACT

ABSTRACT Objective To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters. Subjects and methods This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women. Free androgen index (FAI) and homeostasis model assessment (HOMA-IR), as well as LAP, VAI, and anthropometric indices, were calculated. The regions of interest (ROIs) in body composition and body composition indices were evaluated using a dual X-ray absorptiometry (DXA). Overall, 32 variables were selected as markers of body fat distribution. Results Among the 32 markers evaluated, 29 correlated with LAP, whereas 25 correlated with VAI, 19 with body fat (%), and 30 with A/G ratio. Additionally, some markers correlated with the four adiposity indices evaluated: ROIs, except for total mass and leg fat (%); body composition (body mass index, waist circumference, and hip circumference) indices; fasting insulin; and C-reactive protein. Conclusion LAP and VAI may be sensitive measures for screening and preventing metabolic syndrome and insulin resistance in PCOS, with LAP being more sensitive than VAI, and the A/G ratio may be more sensitive than body fat percentage.

ABSTRACT

BACKGROUND: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults.PURPOSE: Here we evaluated the ability of LAP to predict NAFLD in obese children.METHODS: Eighty obese children (38 girls; age 6–18 years) were included. Anthropometric measurements and biochemical values were obtained from the patients’ medical records. LAP was calculated as [waist circumference (WC) (cm) – 58]×triglycerides (mmol/L) in girls; [WC (cm) – 65]×triglycerides (mmol/L) in boys. The minLAP and adjLAP were described (3% and 50% of WC values, respectively) and the total/high-density lipoprotein cholesterol index (TC/HDL-C) was calculated. NAFLD was observed on ultrasound, and patients were divided into 3 groups by steatosis grade (normal, grade 0; mild, grade 1; moderate-severe, grade 2–3). The area under the curve (AUC) and appropriate index cutoff points were calculated by receiver operator characteristic analysis.RESULTS: LAP was positively correlated with puberty stage (rho=0.409; P<0.001), fasting insulin (rho=0.507; P<0.001), homeostasis model assessment of insulin resistance (rho=0.470; P<0.001), uric acid (rho=0.522; P<0.001), and TC/HDL-C (rho=0.494; P<0.001) and negatively correlated with HDL-C (rho=-3.833; P<0.001). LAP values could be used to diagnose hepatosteatosis (AUC=0.698; P=0.002). The LAP, adjLAP, and minLAP cutoff values were 42.7 (P=0.002), 40.05 (P=0.003), and 53.47 (P=0.08), respectively. For LAP, the differences between the normal and mild groups (P=0.035) and the normal and moderate-severe groups were statistically significant (P=0.037), whereas the difference between the mild and moderate-severe groups was not (P>0.005). There was a statistically significant difference between the normal and mild groups for adjLAP (P=0.043) but not between the other groups (P>0.005). There was no significant intergroup difference in minLAP (P>0.005).CONCLUSION: LAP is a powerful and easy tool to predict NAFLD in childhood. If LAP is ≥42.7, NAFLD should be suspected. This is the first study to assess LAP diagnostic accuracy for childhood obesity.

ABSTRACT

ABSTRACT The lipid accumulation product (LAP) index is an emerging cardiovascular risk marker. We aimed to assess the accuracy of this index as a marker of cardiovascular risk in HIV-infected patients. A cross-sectional study of 133 HIV-infected patients on antiretroviral drugs and 20 non-infected controls was conducted at the outpatient clinic of a referral center of infectious and parasitic diseases. Evaluations included LAP index, homeostasis model assessment (HOMA) index, anthropometric measurements, blood pressure, glucose tolerance test, and cholesterol and triglyceride levels. Body mass index (BMI) was similar in both groups; however, waist circumference was greater in the HIV-infected patients. Triglyceride levels were significantly higher (p < 0.001) and HDL cholesterol levels were lower in HIV-infected patients (p < 0.001). Plasma glucose (p = 0.01) and insulin (p = 0.005) levels two hours after a glucose load, HOMA-IR index (p < 0.001) and LAP index (p < 0.001) were higher in the HIV-infected patients. A positive and significant correlation was found between HOMA-IR index and LAP (r = 0.615; p < 0.01), BMI (r = 0.334; p < 0.01) and waist circumference (r = 0.452; p < 0.01) in the HIV-infected patients. In male HIV-infected patients and controls, ROC curve analyses revealed that the best cut-off value of LAP to define the presence of insulin resistance was 64.8 (sensitivity 86%, specificity 77% and area under the curve 0.824). These results confirm that insulin resistance is more common in HIV-patients on antiretroviral drugs than in HIV-negative controls. A positive and significant correlation was found between the LAP index and the HOMA index, with LAP ≥ 64.8 constituting an additional risk factor for cardiovascular disease in male HIV patients.

ABSTRACT

Abstract Objective To analyze the association between the indirect methods of evaluating insulin resistance (IR) and blood pressure, anthropometric and biochemical parameters in a population of polycystic ovary syndrome (PCOS) patients. Methods Cross-sectional study performed at the Hospital Universitário de Brasília (HUB, in the Portuguese acronym) involving PCOS patients diagnosed from January 2011 to January 2013. Four indirect methods, namely, fasting blood insulin level, fasting glucose/insulin ratio (G/I), homeostatic model-assessment-insulin resistance (HOMA-IR), and the quantitative insulin sensitivity check index (QUICKI), were used to obtain the IR diagnosis. The data were analyzed using the test of proportions, the Chisquare test, and Fisher exact test, when indicated. Results Out of the 83 patients assessed, aged 28.79 ± 5.85, IR was found in 51.81- 66.2% of them using the G/I ratio and the QUICKI, respectively. The test of proportions did not show a significant difference between the methods analyzed. The proportion of IR diagnoses was statistically higher in obese women than in women with normal body mass index (BMI). We observed a statistically significant association between all the methods for diagnosing IR and BMI, waist circumference (WC) and lipid accumulation product (LAP). With regards to arterial hypertension (AH), we observed a significant association according to three methods, with the exception of the ratio G/I. Conclusion Insulin resistance prevalence varied according to the diagnostic method employed,with no statistical difference between them. The proportion of IR diagnoses was statistically higher in obese women than in women with normal BMI.We observed a significant association between IR andWC, BMI, LAP, as well as dyslipidemia and AH in a high proportion of patients.


Resumo Objetivo Analisar a associação entre os métodos indiretos de avaliação de resistência à insulina (RI) e parâmetros pressóricos, antropométricos e bioquímicos em uma população de pacientes com síndrome dos ovários policísticos (SOP). Métodos Estudo transversal realizado no Hospital Universitário de Brasília (HUB), envolvendo pacientes que apresentaram o diagnóstico de SOP no período de janeiro de 2011 a janeiro de 2013. O diagnóstico de RI foi obtido por meio de quatro métodos indiretos: insulinemia de jejum, relação glicemia de jejum/insulinemia de jejum (G/I), avaliação da resistência à insulina através do modelo homeostático (HOMA-IR) e índice quantitativo de sensibilidade à insulina (QUICKI). Os dados foram analisados utilizando o teste de proporções, o teste do Qui-quadrado e o teste exato de Fisher, quando indicado. Resultados Foram avaliadas 83 pacientes com idade média de 28,79 ± 5,85 anos. A RI foi diagnosticada em 51,81-66,27% dos casos pela relação G/I e QUICKI, respectivamente, e o teste de proporções não evidenciou diferença significativa entre osmétodos analisados. A proporção de diagnósticos de RI foi estatisticamente maior em mulheres obesas em comparação à proporção de mulheres com índice de massa corporal (IMC) normal. Foi observada uma associação estatisticamente significativa entre todos os métodos diagnósticos de RI e IMC, circunferência da cintura (CC) e produto de acumulação lipídica (LAP). Quanto à hipertensão arterial (HA), foi observada associação significativa de acordo com três métodos, com exceção da relação G/I. Conclusão A prevalência de RI variou conforme o método diagnóstico utilizado, mas não houve diferença estatística entre eles. A proporção de diagnósticos de IR foi maior nas mulheres obesas do que naquelas com peso normal. Foi observada associação significativa entre RI e CC, IMC e LAP, assim como com dislipidemia e HA em uma proporção elevada de pacientes.

ABSTRACT

@#Objective To investigate the relationship between subclinical hypothyroidism (SCH) and visceral adipose tissue. Methods A total of 68 SCH subjects from medical examination center and inpatient department of our hospital and 100 healthy controls matched for age and sex were enrolled in this study. The patient gender, blood pressure (SBP/DBP), anthropometric measurements, lipid profile, lipid accumulation product (LAP) and visceral adipose area (VA) were compared between two groups. The Sperman’s correlation was used to analyze the correlation between thyroid stimulating hormone (TSH) and variables, and the Binary logistic regression analysis was used to analyze the impact of variables on SCH. Results The waist circumference (WC), waist to hip ratio (WHR), non high density lipoprotein cholesterol (nonHDL-C), three acylglycerol (TG), TSH, LAP and VA were higher in SCH subjects than that in the healthy controls (P<0.05), while HDL-C was lower in SCH subjects (P<0.05). There were no significant differences in sex, age, body mass index (BMI), SBP, DBP, total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) between two groups (P<0.05). Correlation analysis showed that TSH was positively correlated with WC, TG, nonHDL-C, LAP and VA, and negatively correlated with HDL-C (P<0.05). There was no significant correlation between TSH and age, BMI, WHR, TC and LDL-C (P> 0.05). Binary logistic regression analysis showed that female and low level of HDL-C were risk factors of SCH, while the effects of VA and LAP on SCH were not statistically significant. Conclusion Our findings show that the dyslipidemia and VA increase are more serious in subjects with SCH than those with normal thyroid function and healthy controls, which suggest that SCH is closely related to abdominal obesity.

ABSTRACT

Objective@#To explore the lipid accumulation product (LAP) formula for Beijing adults and to investigate the relationship between lipid accumulation product and hypertension, as well as diabetes.@*Methods@#A cross-sectional study with a representative sample of 19 606 residents in Beijing aged 18-79 years was conducted in 2011. The sex-specific hypothetical minimum waist circumference (WC) was calculated in order to obtain the more applicable LAP formula. Multivariate logistic regression was used to analyze the associations of LAP, combination of LAP and body mass index (BMI) with hypertension and diabetes.@*Results@#The LAP formula for Beijing adults was established as follows: LAP (male)= (WC-61.3) × TG, and LAP (female)= (WC-55.6) × TG. There was an obvious trend of increased risk of hypertension and diabetes with an increment in the tertiles of the LAP both in men and women. The OR (95%CI) for hypertension in the group with highest tertile LAP was 3.62 (3.11-4.22) in men, and 5.79 (4.84-6.93) in women, compared with the lowest tertile group, respectively; and the corresponding OR for diabetes was 3.47 (2.73-4.41) in men, and 4.10 (2.90-5.80) in women, respectively. Compared with the lowest tertile of LAP and normal BMI group, the OR (95%CI) for hypertension in the highest tertile of LAP and obesity group was 6.79 (5.50-8.37) in men, and 9.75 (7.76-12.25) in women, respectively; while the corresponding value for diabetes was 3.97 (2.87-5.49) in men, and 4.13 (2.78-6.14) in women, respectively.@*Conclusion@#The elevated level of LAP was associated with an increased risk of hypertension and diabetes among Beijing adults. LAP could be an important predictor for hypertension and diabetes.

ABSTRACT

A Síndrome Metabólica (SM) tem se tornado um importante problema de saúde pública nos últimos anos tanto pela sua alta magnitude quanto pela sua forte relação com as doenças cardiovasculares (DCV) e o diabetes mellitus do tipo II (DM 2), duas das principais causas de mortalidade em todo o mundo. Portanto, se faz necessária a identificação precoce e precisa de indivíduos em alto risco de desenvolver SM de maneira simples e ágil. Nesse sentido, o Lipid Accumulation Product {LAP) e um novo biomarcador de acúmulo de lipídeos central relacionado ao risco de síndrome metabólica (SM), diabetes e doença cardiovascular. Assim,o objetivo deste estudo foi analisar a capacidade do LAP para identificar indivíduos com SM.Trata-se de um estudo epidemiológico transversal conduzido com 211 funcionários do campus saúde de uma universidade publica de Belo Horizonte - MG. Foi aplicado questionário sobre características demográficas, socioeconômicas, antropométricas e do estilo de vida. A SM foi definida de acordo com os critérios propostos pela NCEP-ATP IIJ atualizada, IDF, AHAJNHBLI e NCEP-ATP 111/IDF harmonizado. A Receiver Operator Characteristic curve (curva ROC) foi utilizada para encontrar o ponto de corte do LAP que melhor identificasse indivíduos com SM diagnosticados segundo diferentes definições. A prevalência da SM foi de: 27,0% (IC 95%: 21,1-33,5) NCEP-ATP III atualizada; 33,2% (IC95%: 26,9-40,0) IDF; 28,4% (IC 95%: 22,5-35,0) AHAJNHBLI e 38,4% (IC 95%: 32,0-45,2)NCEP-ATP 111/IDF harmonizada. As análises das curvas ROC mostraram que o LAP foi discriminador significativo para a SM em todas as definições diagnósticas. Os melhores pontos de corte para identificar a SM foram: 41,10 NCEP-ATP III atualizada (86% sensibilidade, 82,5% especificidade); 37,85 IDF (81,4% sensibilidade, 80,9% sensibilidade);39,39 AHAJNHBLI (88,3% sensibilidade, 81,5% ...


Metabolic syndrome (MS) has become a major public health problem in recent years both forits high magnitude and for its strong relationship with cardiovascular disease (CVD) and diabetes mellitus type II (DM2), two of the main causes of mortality world wide. Therefore, itis necessary an early and accurate identification of individuals at high risk of developing MSin a simple and agile way. Accordingly, the Lipid Accumulation Product (LAP) is a novel biomarker of central lipid accumulation related to risk of metabolic syndrome (MS), diabetes and cardiovascular disease. The objective of this study was to analyze the LAP's ability toidentify individuals with MS. This was a cross-sectional epidemiological study conducted with 211 employees of health campus at a public university of Belo Horizonte city - Minas Gerais State - Brazil. Questionnaire was applied to assess demographic, socioeconomic, anthropometric and lifestyle characteristics. MS was defined according to criteria proposed by NCEP-ATP ill updated, IDF, AHNNHBLI and harmonized NCEP-ATP 111/IDF. TheReceiver Operator Characteristic curve (ROC) was used to find the LAP cutoff that best identified individuals with MS diagnosed according to different definitions. The prevalence ofMS was: 27.0% (95% CI: 21.1to33.5) NCEP-ATP III updated; 33.2% (95% CI: 26.9 to 40.0)IDF; 28.4% (95% CI: 22.5 to 35.0) AHNNHBLI and 38.4% (95% CI: 32.0 to 45.2) harmonized NCEP-A TP 111/IDF. The analysis of ROC curves showed that the LAP was significant discriminator for MS in all diagnostic criteria. The best point cutoffs to identify the MS were 41.10 NCEP-ATP III updated (86% sensitivity, 82.5% specificity); 37.85 IDF(81.4% sensitivity, 80.9% sensitivity); 39.39 AHNNHBLI (88.3% sensitivity, 81.5% specificity) and 33.18 harmonized NCEP-ATP III/IDF (sensitivity 84% and specificity80.8% ). It is concluded that the LAP was associated with MS and had strong and reliable diagnostic accuracy for identifying individuals with MS.

ABSTRACT

BACKGROUND: Lipid accumulation product (LAP) is a novel biomarker of central lipid accumulation related to risk of diabetes and cardiovascular disease. In this study, we assessed the association of LAP with glucose homeostasis, lipid and lipid peroxidation, and subclinical systemic inflammation in diabetic patients. METHODS: Thirty-nine male and 47 female type 2 diabetic patients were assessed for anthropometrics and biochemical measurements. LAP was calculated as [waist circumference (cm)-65]x[triglycerides (mmol/L)] in men, and [waist circumference (cm)-58]x[triglycerides (mmol/L)] in women. Associations of LAP with fasting glucose, insulin, insulin resistance index, lipid and lipoprotein levels, malondialdehyde, and high-sensitive C-reactive protein (hs-CRP) were assessed. RESULTS: Mean age and LAP index were 53.6+/-9.6 and 51.9+/-31.2 years, respectively. After adjustments for age, sex and body mass index status, a significant positive correlation was observed between LAP index and fasting glucose (r=0.39, P<0.001), and homeostasis model assessment of insulin resistance (r=0.31, P<0.05). After additional adjustment for fasting glucose levels, antidiabetic and antilipidemic drugs, the LAP index was also correlated to total cholesterol (r=0.45, P<0.001), high density lipoprotein cholesterol (HDL-C) levels (r=-0.29, P<0.05), triglycerides to HDL-C ratio (r=0.89, P<0.001), malondialdehyde (r=0.65, P<0.001), and hs-CRP levels (r=0.27, P<0.05). CONCLUSION: Higher central lipid accumulation in diabetic patients was related to higher insulin resistance, oxidative stress and systemic inflammation.

ABSTRACT

Objective To investigate the correlation between lipid accumulation product (LAP), visceral adiposity index (VAI) and high-sensitivity C-reactive protein (hs-CRP) in adults, and explore whether to use such correlation as indications is superior to the traditional body fat index based on body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR) and waist-height ratio (WHtR). Methods The present work was a cross-sectional study involving 501 healthy adults (321 males and 180 females) from the community of Chongqing Municipality. Anthropometric indexes [height, weight, WC, hip circumference (HC)], blood pressure (BP), fasting lipid profile and levels of fasting and post-load glucose, insulin and hs-CRP were measured, and BMI, WHR, WHtR, fasting insulin resistant homeostasis model assessment (HOMA-IR), LAP and VAI were calculated. The correlations between hs-CRP and other variables were analyzed. Results Following the elevation of titer of the hs-CRP, LAP, VAI, BMI, WC, WHR, WHtR, BP, glucose level, HOMA-IR, insulin, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (ApoB) increased (P<0.05), while high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (ApoA1 levels declined (P<0.0001). Pearson's correlation analysis demonstrated that hs-CRP was correlated with all variances (P<0.01) except for total cholesterol (TC) (P=0.18l) and LDL-C (P=0.325). According to forward stepwise multiple regression analysis with hs-CRP as the dependent variance, WC was the only variance entering the regression model. Conclusion LAP, VAI levels are correlated with hs-CRP level but not the major determinant factors of hs-CRP. WC is stronger than other variances in the association with hs-CRP in adults, and is still an independent predictor of inflammation.

ABSTRACT

Objective To measure the association between lipid accumulation product (LAP) or body mass index (BMI) and diabetes. Methods In this prospective study, subjects were recruited and followed up for more than five years from the program "Prevention of Multiple Metabolic Disorders and MS in Jiangsu Province" (PMMJS). A total number of 3598 people participating in the follow-up program, with complete information. Incidence rates of diabetes and relative risk in different levels of LAP and BMI were compared and analyzed. Areas under the receiver operation characteristic curve for obesity indicators such as LAP, BMI, waist circumference (WC), waist-to-hip ratio (WHR) in predicting diabetes of cohort population were calculated. Results The number and the cumulative incidence of diabetes increased with the LAP levels in both men and women. After adjusting for age and other traditional risk factors on diabetes, the adjusted risk ratios (aRR) value of diabetes were 4.33(1.34-14.01) for men and 5.04(2.06-12.34) for women, between the highest and the lowest level of LAP groups. When further adjusted for BMI, the aRR value decreased to 3.15 (1.13-8.80) for men and 4.84(2.16-10.84) for women. The number and the cumulative incidence of diabetes also increased with the BMI levels in both men and women but not significantly as the LAP showed, and the aRR values were 1.34 (0.61-2.93) for men and 1.69 (0.91-3.06) for women in the highest level of BMI group, when compared with the lowest level group. Again, when further adjusted for LAP, the aRR values decreased to 1.23 (0.59-2.69) for men and 1.39(0.74-2.60) for women. The area under the ROC curve(AUC) for the four kinds of obesity indicators in predicting diabetes in the descending order were LAP, WHR, WC, BMI in both men and women. Conclusion LAP seemed more associated to diabetes than to BMI. When comparing with weight gain, diabetes might be more closely associated with the lipid accumulation product.
