Analysis of the Correlation Between Visceral Fat Area and Insulin Resistance in Patients with Type 2 Diabetes and Abdominal Obesity

Objective: To analyze the correlation between visceral fat area and insulin resistance index (HOMA-IR) in patients with type 2 diabetes mellitus (T2DM) and abdominal obesity and to provide a reference for screening and related research of such patients. Methods: Two hundred patients with T2DM admitted to Guandu People’s Hospital of Kunming were included. The study was carried out from October 2022 to December 2023. The patients were divided into three groups according to different abdominal visceral fat areas (VFA): Group A (n = 65) was less than 75cm2, Group B (n = 75) was 75-100 cm2, and Group C (n = 60) was greater than 100 cm2. The subjects in the three groups were all tested for glycated hemoglobin (HbA1c), fasting insulin (FINS), and fasting blood glucose (FPG). Height and weight were measured to calculate body mass index (BMI). The HOMA-IR and TYG (fasting triglyceride and glycemic index) were also calculated. Changes in the BMI, VFA, HOMA-IR, and TYG levels were observed in the three groups. Results: The VFA, BMI, HbA1c, FPG, FINS, HOMA-IR, and TYG of the patients all increased, with a more significant increase in the BMI, FINS, HOMA-IR, and TYG levels (P < 0.01). Multiple linear stepwise regression analyses used visceral fat area (VFA) as the dependent variable. The results showed that VFA was closely related to BMI, FINS, HOMA-IR, and TYG. Conclusion: Early reduction of VFA to reduce insulin resistance may be a better treatment and effective method for T2DM, providing powerful measures and new strategies for effective blood sugar control and early prevention in the treatment of metabolic diseases.

Age-dependent Changes in Skeletal Muscle Mass and Visceral Fat Area in a Chinese Population

Objective:The present study was conducted to demonstrate the age-dependent changes in skeletal muscle mass and visceral fat area in a population of Chinese adults aged 30-92 years old.Methods:A total of 6669 healthy Chinese men and 4494 healthy Chinese women aged 30-92 years old were assessed for their skeletal muscle mass and visceral fat area.Results:The results showed age-dependent decreases in the total skeletal muscle mass indexes in both men and women aged 40-92 years old as well as age-dependent increases in the visceral fat area in men aged 30-92 years old and in women aged 30-80 years old.Multivariate regression models showed that the total skeletal muscle mass index was positively associated with the body mass index and negatively associated with the age and visceral fat area in both sexes.Conclusion:The loss of skeletal muscle mass becomes obvious at approximately 50 years of age,and the visceral fat area commences to increase at approximately 40 years of age in this Chinese population.

Correlations of Body Mass Index, Japan-Defined and IDF-Defined Waist Circumference, Visceral and Subcutaneous Fat Area with Metabolic Parameters in Japanese Patients with Type 2 Diabetes

Obesity is included in the definition of metabolic syndrome. However, there are many controversies surrounding the evaluation of obesity such as body mass index (BMI) and waist circumference (WC) in the definition of metabolic syndrome among various populations. To understand precisely how various anthropometric indices of obesity influence metabolic parameters, we studied the correlations of BMI, WC (Japanese criteria), WC (IDF criteria), visceral fat area (VFA), subcutaneous fat area (SFA) and the VFA/SFA ratio with metabolic parameters in patients with type 2 diabetes. The influences of BMI and WC on diastolic blood pressure and HDL-cholesterol were larger than VFA, whereas the influences of visceral fat area on triglyceride, very low-density lipoprotein-cholesterol, C-peptide and high-sensitivity C-reactive protein were larger than BMI and WC. WC (IDF) was the strongest determinant of adiponectin among anthropometric indices. Present study showed significant different associations of BMI, Japan- and IDF-defined WC, VFA, SFA and the VFA/SFA ratio with blood pressure, glucose and lipid metabolism, and adipocytokines in Japanese patients with type 2 diabetes.

Impact of Lifestyle Intervention on the Estimated Visceral Fat Area and Skeletal Muscle Mass in Men with Obesity

Background: The lifestyle modification remains the fundamental approach for the obesity treatment. The aim of this study is to demonstrate the effect of the multimodal lifestyle intervention on the estimated visceral fat area versus changes in musculoskeletal mass in a cohort of adult men with obesity. Subjects and Methods: A retrospective cohort study in which the file of eighty-two male subjects, aged 20 - 60 years, was studied for three months. Patients had been instructed to follow a balanced-hypocaloric diet, physical activity plan and general advice for combating the unhealthy lifestyle habits through the study period. Those who succeeded to loss > 5% of their body weight were classified as weight loser (WL) group, while others as weight resistant (WR) group. The results of In Body-720 bioelectric impedance analysis were used to report the fat mass (FM), visceral fat area (VFA), skeletal muscle mass (SMM), SMM/VFA ratio, osseous mass (OM), and basal metabolic rate (BMR) before and after the study period. Anthropometric measures, glucose, and lipid profile were also analyzed. Paired t-test was used to detect the significance of change between before and after measures, independent sample t-test was used to compare WL vs. WR groups. Results: There were significant decreases in weight, FM (p 0.05) and VFA (p 0.001), in addition to a significant rise of SMM/VFA ratio (p 0.05), together with insignificant changes of osseous mass, SMM and BMR after 3 months. Additionally, total cholesterol, low-density lipoprotein, and triglycerides were significantly reduced (P 0.05). The percentages of reduction in weight, FM and VFA in WL vs. WR groups were highly significant (p 0.001), while the percentages of change in SMM, SMM/VFA ratio and BMR were significant (p 0.05). Conclusion: Lifestyle modification might be effective in production of positive changes in the body composition of patients with obesity. These changes were more significant in weight losers.

A pilot study in relationship among changes in visceral fat area, waist circumference and body weight in Japanese freshmen students

We investigated the relationship among delta (delta represents changes in parameters) visceral fat area, waist circumference and body weight in Japanese freshmen students. Visceral fat was measured at the umbilical level using computerized tomography scanning at baseline study and 6 months later. Body weight and height, as well as waist circumference were also measured. We found that visceral fat area, waist circumference, and body weight significantly correlated with each other at baseline, and 6 months later, delta visceral fat area and changes in % visceral fat area significantly correlated with delta waist circumference and delta body weight in female and in total subjects. In addition, based on the predictive linear equations from the regression analysis, we found that 1kg of delta body weight corresponded to 0.83 cm of delta waist circumference, and 1kg of delta body weight and 1cm of delta waist circumference corresponded to 9.41% and 7.80% of changes in visceral fat area, respectively, in total subjects. The present results suggest that delta visceral fat area is closely related to delta body weight and delta waist circumference in Japanese freshmen students.

Association of ratios of visceral fat area/subcutaneous fat area and muscle area/standard body weight at T12 CT level with the prognosis of acute respiratory distress syndrome

Background:It is well-known that body composition metrics can influence the prognosis of various diseases.This study investigated how body composition metrics predict acute respiratory distress syndrome(ARDS)prognosis,focusing on the ratio of visceral fat area(VFA)to subcutaneous fat area(SFA),SFA to standard body weight(SBW),VFA to SBW,and muscle area(MA)to SBW.These metrics were assessed at the level of the twelfth thoracic vertebra(T12 computed tomography[CT]level)to determine their correlation with the outcomes of ARDS.The goal was to utilize these findings to refine and personalize treatment strategies for ARDS.Methods:Patients with ARDS admitted to the intensive care units(ICUs)of three hospitals from January 2016 to July 2023 were enrolled in this study.Within 24 hours of ARDS onset,we obtained chest CT scans to mea-sure subcutaneous fat,visceral fat,and muscle area at the T12 level.We then compared these ratios between survivors and non-survivors.Logistic regression was employed to identify prognostic risk factors.Receiver oper-ating characteristic(ROC)curve analysis was utilized to determine the optimal cutofffor predictors of in-hospital mortality.Based on this cutoff,patients with ARDS were stratified.To reduce confounding factors,1:1 propensity score matching(PSM)was applied.We conducted analyses of clinical feature and prognostic differences pre-and post-PSM between the stratified groups.Additionally,Kaplan-Meier survival curves were generated to compare the survival outcomes of these groups.Results:Of 258 patients with ARDS,150 survived and 108 did not.Non-survivors had a higher VFA/SFA ra-tio(P<0.001)and lower SFA/SBW and MA/SBW ratios(both P<0.001).Key risk factors were high VFA/SFA ratio(OR=2.081;P=0.008),age,acute physiology and chronic health evaluation(APACHE)II score,and lac-tate levels,while MA/SBW and albumin were protective.Patients with a VFA/SFA ratio≥0.73 were associated with increased mortality,while those with an MA/SBW ratio>1.55 cm^(2)/kg had lower mortality,both pre-and post-PSM(P=0.001 and P<0.001,respectively).Among 170 patients with pulmonary-origin ARDS,87 survived and 83 did not.The non-survivor group showed a higher VFA/SFA ratio(P<0.001)and lower SFA/SBW and MA/SBW(P=0.003,P<0.001,respectively).Similar risk and protective factors were observed in this cohort.For VFA/SFA,a value above the cutoffof 1.01 predicted higher mortality,while an MA/SBW value below the cutoffof 1.48 cm2/kg was associated with increased mortality(both P<0.001 pre-/post-PSM).Conclusions:Among all patients with ARDS,the VFA to SFA ratio,MA to SBW ratio at the T12 level,age,APACHE II score,and lactate levels emerged as independent risk factors for mortality.

肾周脂肪厚度与高尿酸血症患者痛风发作及发作频率的相关性研究

目的探讨肾周脂肪厚度与高尿酸血症患者痛风发作及发作频率之间的关系。方法回顾性纳入2020年11月—2021年7月在首都医科大学附属北京潞河医院内分泌代谢与免疫性疾病中心接受治疗的高尿酸血症患者为研究对象,将其分为无痛风发作组(n=20)与有痛风发作组(n=80)。根据发作频率,将痛风发作组患者进一步分为发作1次组(n=44)与反复发作组(n=36)。收集纳入患者的人口学特征、疾病相关资料、内脏脂肪面积及肾周脂肪厚度,比较组间差异,并通过回归分析确定肾周脂肪厚度与痛风发作及发作频率的相关性。结果与无痛风发作组患者相比,有痛风发作组患者的肾周脂肪厚度增加[(1.09±0.39)cm比(1.37±0.45)cm,P=0.012];在有痛风发作组患者中,与发作1次组患者相比,反复发作组患者的肾周脂肪厚度增加[(1.26±0.40)cm比(1.50±0.47)cm,P=0.014]。Logistic回归分析显示,肾周脂肪厚度增加不仅与痛风发作存在相关,且与发作频率亦存在相关。结论肾周脂肪厚度与痛风发作及发作频率存在相关。
