Abdominal fat distribution measured by ultrasound and aerobic fitness in young Danish men born with low and normal birth weight

Abdominal subcutaneous and visceral adipose tissue thickness was examined by ultrasound in 17 men with low birth weight (LBW) and 26 with normal BW control individuals to determine if abdominal obesity in LBW individuals is due to increased visceral or subcutaneous fat mass/thickness, or both. Men born with LBW had an increased waist-to-hip ratio (P = 0.04), greater abdominal fat thickness (P = 0.05) and increased visceral (VAT) and subcutaneous adipose tissue (SAT) thickness compared with controls, however the latter not statistically significant (P = 0.08, P = 0.10). A significant difference between birth weight groups in both SAT (P = 0.04) and VAT (P = 0.03) was found after adjustment for weight, whereas no significant difference in either SAT (P = 0.93) or VAT (P = 0.30) was found after adjustment for BMI. Increased waist-to-hip ratio in LBW individuals is due to increased total abdominal fat including both subcutaneous and visceral fat.     

各型多囊卵巢综合征患者内分泌及代谢特点分析

目的:探讨各型多囊卵巢综合征(PCOS)患者内分泌及代谢特征,为PCOS的合理治疗及并发症防治提供依据。方法:将54例PCOS患者,根据体重指数(BMI)将其分为肥胖PCOS组30例、非肥胖PCOS组24例,同时选择肥胖对照组20例和非肥胖对照组22例。测定并计算所有研究对象的BMI、腰臀比(WHR)、收缩压(SBP)、舒张压(DBP)、体脂含量、胰岛素抵抗指数(HOMA-IR)、胰岛素敏感指数(ISI),抽血检测血清黄体生成素(LH)、卵泡刺激素(FSH)、雌二醇(E2)、泌乳素(PRL)、睾酮(T)、空腹血糖(FPG)和胰岛素(FINS)、低密度脂蛋白(TC)、甘油三酯(TG)水平。结果:两PCOS组的LH水平及T水平均显著高于其相应的对照组(P0.01);肥胖PCOS组的TG水平高于非肥胖PCOS组,而TC水平高于其对照组(P均0.05);肥胖PCOS组的FINS,HOMA-IR均显著高于非肥胖PCOS组(P0.01),且两PCOS组的HOMA-IR均显著高于其对照组(P0.05);肥胖PCOS组的ISI显著低于非肥胖PCOS组(P0.01),且非肥胖PCOS组的ISI显著低于其对照组(P0.05)。PCOS组血清T与LH和TC呈正相关,PCOS组HOMA-IR与BMI、WHR、体脂含量、收缩压、舒张压、FPG、FINS均呈正相关。结论:高雄激素血症(hyperandrogenemia,HA)、胰岛素抵抗(insulin resistance,IR)和高胰岛素血症(hyperinsulinemia,HI)为PCOS的基本特征,肥胖的PCOS患者更易出现IR,要重视PCOS的远期并发症。     

Upper trunk fat assessment and its relationship with metabolic and biochemical variables and body fat in polycystic ovary syndrome

Background: Fat accumulation in the upper region of the body is common in polycystic ovary syndrome (PCOS) and is associated with metabolic complications. The present study aimed to assess the relationship between trunk circumference, metabolic indicators, and abdominal and visceral fat in obese PCOS women. Methods: The weight, fat mass, and subcutaneous arm fat (SAF) of 30 obese PCOS women and 15 healthy controls matched for age and body mass index were evaluated by bioelectrical impedance analysis. Trunk (TrC), neck (NC) and hip circumferences were measured, and the trunk/hip (Tr/H) ratio was determined. Total abdominal fat (TAF), visceral fat (VF) and trunk fat (TrF) were determined by computed tomography. Biochemical evaluation included glycaemia, insulinaemia, testosterone and lipid profile, insulin resistance (IR) was assessed by the QUICKI index. Results: In the PCOS group, there were positive correlations between NC and TAF (r = 0.49, P < 0.0006), TrC and VF (r = 0.62, P = 0.01), and NC and VF (r = 0.70, P < 0.0002). There was good correlation between TrC and TrF (r = 0.69, P = 0.003). TrF correlated with triglycerides levels positively (r = 0.44, P = 0.02). Women with PCOS and IR had a larger quantity of VF and TrF, but a smaller amount of SAF. Within the PCOS group, women with Tr/H ratio above the median had higher basal insulin levels and lower QUICKI indices compared to women presenting a Tr/H ratio below the median. Conclusions: TrC is associated with important metabolic variables in PCOS, proving to be a valuable and innovative tool for assessment of body adiposity distribution in obese PCOS women.     

Body mass index and waist circumference independently contribute to the prediction of nonabdominal, abdominal subcutaneous, and visceral fat

BACKGROUND: It is unknown whether the ability of waist circumference (WC) to predict health risk beyond that predicted by body mass index (BMI) alone is explained in part by the ability of WC to identify those with elevated concentrations of total or abdominal fat. OBJECTIVE: We sought to determine whether BMI and WC independently contribute to the prediction of non-abdominal (total fat - abdominal fat), abdominal subcutaneous, and visceral fat. DESIGN: Fat distribution was measured by magnetic resonance imaging in 341 white men and women. Multiple regression analysis was performed to measure whether the combination of BMI and WC explained a greater variance in non-abdominal, abdominal subcutaneous, and visceral fat than did BMI or WC alone. These fat depots were also compared after a subdivision of the cohort into 3 BMI (normal, overweight, and class I obese) and 3 WC (low, intermediate, and high) categories according to the classification system used to identify associations between BMI, WC, and health risk. RESULTS: Independent of age and sex, the combination of BMI and WC explained a greater variance in non-abdominal, abdominal subcutaneous, and visceral fat than did either BMI or WC alone (P < 0.05). For non-abdominal and abdominal subcutaneous fat, BMI was the strongest correlate; thus, by adding BMI to WC, the variance accrued was greater than when WC was added to BMI. However, when WC was added to BMI, the added variance explained for visceral fat was greater than when BMI was added to WC. Furthermore, within each of the 3 BMI categories studied, an increase in the WC category was associated with an increase in visceral fat (P < 0.05). CONCLUSIONS: BMI and WC independently contribute to the prediction of non-abdominal, abdominal subcutaneous, and visceral fat in white men and women. These observations reinforce the importance of using both BMI and WC in clinical practice.     

A 360-degree overview of body composition in healthy people: Relationships among anthropometry,ultrasonography, and dual-energy x-ray absorptiometry

ObjectiveThe aim of this study was to test the relationship between anthropometry, ultrasonography, and dual-energy x-ray absorptiometry (DXA) for the assessment of body composition in clinical practice.MethodsThe study was carried out in Italian blood donor volunteers belonging to five different age groups (18–70 y old; 25 men and 25 women per group; N = 250 participants; n = 125 men, n = 125 women). A complete history was collected and routine blood analyses were performed to confirm healthy status. All participants were submitted to whole-body DXA (tricompartmental analysis, regional, and total body), ultrasonography (abdominal adiposity evaluation), and anthropometric measurements. DXA was used as gold standard and its biomarkers were taken as reference for fat–lean mass balance, central–peripheral fat distribution, central or visceral fat, and subcutaneous fat.ResultsAnthropometric and ultrasound parameters were closely associated with most of DXA parameters. Composite markers representative of central and abdominal visceral fat compartments were significantly correlated with waist circumference, waist-to-hip ratio, and intra-abdominal fat thickness by ultrasound, in both men and women (P < 0.025). As expected, subcutaneous depots were significantly correlated with maximum subcutaneous fat thickness measured by ultrasonography (P < 0.025).ConclusionsBoth anthropometry and ultrasonography provide a reliable estimate of visceral adipose tissue in a non-obese population compared with DXA, whereas anthropometry prediction of subcutaneous adiposity is weak. Physicians should be aware of the limits of these techniques for the assessment of body composition.

The relationship between anthropometry and body composition from computed tomography: The Mediators of Atherosclerosis in South Asians Living in America Study

Objective: Few studies examine the relationships between anthropometry and the body composition measures they approximate, or whether they differ by sex, and no studies have examined these relationships in South Asians living in the US.

Design: We conducted a cross-sectional study of 871 participants in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study who had BMI?2 and underwent abdominal CT scans for measurement of visceral and subcutaneous fat. Linear regression was used to model the associations between anthropometric measures and naturally log-transformed body composition measures.

Results: All measures of anthropometry, except height, were significantly associated with visceral fat and had a significant non-linear component (p?p?=?.007 for interaction) and waist-to-hip ratio (women 25.9, men 717.4, p?2): 10.3, 14.0; waist circumference (cm): 1.51, 3.36; hip circumference (cm): 2.53, 4.50) with p?Conclusions: In MASALA participants, the relationships of anthropometric measures with visceral and subcutaneous fat appear similar to other race/ethnic groups, but with weaker non-linearity and heterogeneity by sex. Given these results, researchers should consider separate models by sex for US South Asians when approximating subcutaneous fat or when using waist circumference to approximate visceral fat.
