2014年11月在海南省五指山市5个黎族村寨测量了607例(男为308例,女为299例)黎族人体质量、身高等6项体成分指标值,计算了黎族人的体脂率(P_(bf))、瘦体质量(m_l)、脂肪质量(m_f)、瘦体质量指数(I_(lm))、脂肪质量指数(I_(fm))。研究发现,女性体脂率、脂肪质量、脂肪质量指数都明显大于男性,瘦体质量、瘦体质量指数均明显小于男性。随年龄增长,黎族人身高、瘦体质量逐渐减小,体脂率、脂肪质量、脂肪质量指数逐渐增大。受试者特征曲线显示身体质量指数、脂肪质量指数都可以适宜评价黎族人的体脂率,而且脂肪质量指数对体脂率的估算准确性比身体质量指数更高。这也提示脂肪质量指数是比身体质量指数评价肥胖更好的指标。 相似文献

典型黑土耕作区土壤结构对季节性冻融的响应 总被引:3,自引:0,他引:3
以东北典型黑土耕作区土壤为研究对象,通过对一季冻融交替后土壤团聚体、土壤楔入阻力、容重、孔隙度、饱和度、广义土壤结构指数等指标的测定和分析,对比研究了季节性冻融对黑土耕作土壤结构特征的影响.结果表明:季节性冻融加剧了黑土耕作区土壤风干团聚体的分散,但显著降低了水稳性团聚体的破坏率(P0.05),表现出促进其团聚的作用;季节性冻融后黑土土壤楔入阻力降低了15.45%;容重趋于一致,在1.10~1.11g.cm-3之间;固相比例持续增加,总孔隙度与毛管孔隙度均不同程度降低;土壤饱和度总体增加了13.06%,削弱了土壤潜在贮水能力.季节性冻融改善了耕作区的土壤结构,使之更适于耕作.虽然季节性冻融增强了土壤团聚体的抗蚀性,却削弱了土壤的抗冲性,增加了黑土水蚀发生的风险. 相似文献

Obesity is a growing problem in the United States and throughout the world. It is a risk factor for many chronic diseases. The BMI has been used to assess body fat for almost 200 years. BMI is known to be of limited accuracy, and is different for males and females with similar %body adiposity. Here, we define an alternative parameter, the body adiposity index (BAI = ((hip circumference)/((height)(1.5))-18)). The BAI can be used to reflect %body fat for adult men and women of differing ethnicities without numerical correction. We used a population study, the "BetaGene" study, to develop the new index of body adiposity. %Body fat, as measured by the dual-energy X-ray absorptiometry (DXA), was used as a "gold standard" for validation. Hip circumference (R = 0.602) and height (R = -0.524) are strongly correlated with %body fat and therefore chosen as principal anthropometric measures on which we base BAI. The BAI measure was validated in the "Triglyceride and Cardiovascular Risk in African-Americans (TARA)" study of African Americans. Correlation between DXA-derived %adiposity and the BAI was R = 0.85 for TARA with a concordance of C_b = 0.95. BAI can be measured without weighing, which may render it useful in settings where measuring accurate body weight is problematic. In summary, we have defined a new parameter, the BAI, which can be calculated from hip circumference and height only. It can be used in the clinical setting even in remote locations with very limited access to reliable scales. The BAI estimates %adiposity directly. 相似文献

Background
The social valorisation of overweight in African populations could promote high-risk eating behaviours and therefore become a risk factor of obesity. However, existing scales to assess body image are usually not accurate enough to allow comparative studies of body weight perception in different African populations. This study aimed to develop and validate the Body Size Scale (BSS) to estimate African body weight perception.Methods
Anthropometric measures of 80 Cameroonians and 81 Senegalese were used to evaluate three criteria of adiposity: body mass index (BMI), overall percentage of fat, and endomorphy (fat component of the somatotype). To develop the BSS, the participants were photographed in full face and profile positions. Models were selected for their representativeness of the wide variability in adiposity with a progressive increase along the scale. Then, for the validation protocol, participants self-administered the BSS to assess self-perceived current body size (CBS), desired body size (DBS) and provide a “body self-satisfaction index.” This protocol included construct validity, test-retest reliability and convergent validity and was carried out with three independent samples of respectively 201, 103 and 1115 Cameroonians.Results
The BSS comprises two sex-specific scales of photos of 9 models each, and ordered by increasing adiposity. Most participants were able to correctly order the BSS by increasing adiposity, using three different words to define body size. Test-retest reliability was consistent in estimating CBS, DBS and the “body self-satisfaction index.” The CBS was highly correlated to the objective BMI, and two different indexes assessed with the BSS were consistent with declarations obtained in interviews.Conclusion
The BSS is the first scale with photos of real African models taken in both full face and profile and representing a wide and representative variability in adiposity. The validation protocol proved its reliability for estimating body weight perception in Africans. 相似文献13.

Objective
The worldwide prevalence of obesity mandates a widely accessible tool to categorize adiposity that can best predict associated health risks. The body adiposity index (BAI) was designed as a single equation to predict body adiposity in pooled analysis of both genders. We compared body adiposity index (BAI), body mass index (BMI), and other anthropometric measures, including percent body fat (PBF), in their correlations with cardiometabolic risk factors. We also compared BAI with BMI to determine which index is a better predictor of PBF.Methods
The cohort consisted of 698 Mexican Americans. We calculated correlations of BAI, BMI, and other anthropometric measurements (PBF measured by dual energy X-ray absorptiometry, waist and hip circumference, height, weight) with glucose homeostasis indices (including insulin sensitivity and insulin clearance from euglycemic clamp), lipid parameters, cardiovascular traits (including carotid intima-media thickness), and biomarkers (C-reactive protein, plasminogen activator inhibitor-1 and adiponectin). Correlations between each anthropometric measure and cardiometabolic trait were compared in both sex-pooled and sex-stratified groups.Results
BMI was associated with all but two measured traits (carotid intima-media thickness and fasting glucose in men), while BAI lacked association with several variables. BAI did not outperform BMI in its associations with any cardiometabolic trait. BAI was correlated more strongly than BMI with PBF in sex-pooled analyses (r = 0.78 versus r = 0.51), but not in sex-stratified analyses (men, r = 0.63 versus r = 0.79; women, r = 0.69 versus r = 0.77). Additionally, PBF showed fewer correlations with cardiometabolic risk factors than BMI. Weight was more strongly correlated than hip with many of the cardiometabolic risk factors examined.Conclusions
BAI is inferior to the widely used BMI as a correlate of the cardiometabolic risk factors studied. Additionally, BMI’s relationship with total adiposity may not be the sole determinate of its association with cardiometabolic risk. 相似文献14.

Surrogate indexes of visceral adiposity, a major risk factor for metabolic and cardiovascular disorders, are routinely used in clinical practice because objective measurements of visceral adiposity are expensive, may involve exposure to radiation, and their availability is limited. We compared several surrogate indexes of visceral adiposity with ultrasound assessment of subcutaneous and visceral adipose tissue depots in 99 young Caucasian adults, including 20 women without androgen excess, 53 women with polycystic ovary syndrome, and 26 men. Obesity was present in 7, 21, and 7 subjects, respectively. We obtained body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), model of adipose distribution (MOAD), visceral adiposity index (VAI), and ultrasound measurements of subcutaneous and visceral adipose tissue depots and hepatic steatosis. WC and BMI showed the strongest correlations with ultrasound measurements of visceral adiposity. Only WHR correlated with sex hormones. Linear stepwise regression models including VAI were only slightly stronger than models including BMI or WC in explaining the variability in the insulin sensitivity index (yet BMI and WC had higher individual standardized coefficients of regression), and these models were superior to those including WHR and MOAD. WC showed 0.94 (95% confidence interval 0.88–0.99) and BMI showed 0.91 (0.85–0.98) probability of identifying the presence of hepatic steatosis according to receiver operating characteristic curve analysis. In conclusion, WC and BMI not only the simplest to obtain, but are also the most accurate surrogate markers of visceral adiposity in young adults, and are good indicators of insulin resistance and powerful predictors of the presence of hepatic steatosis. 相似文献

Unhealthy dietary pattern increases the risk of obesity and metabolic disorders in growing children and adolescents. However, the way the habitual pattern of breakfast consumption influences body composition and risk of obesity in adolescents is not well defined. Thus, the aim of the present study was to assess any associations between breakfast consumption practices and body composition profiles in 236 apparently healthy adolescents aged 12 to 19 years. A self-administered questionnaire on dietary behaviour and lifestyle practices and a dietary food frequency questionnaire were used. Body composition and adiposity indices were determined using standard anthropometric measurement protocols and dual energy χ-ray absorptiometry (DXA). Mean age of the participants was 15.3±1.9 years. The majority of participants (71.2%) fell in the normal body mass index (BMI) ranges. Breakfast consumption patterns showed that only half of the participants (50%) were consuming breakfast daily. Gender-specific multivariate analyses (ANCOVA) showed that in both boys and girls, those eating breakfast at least 5 times a week had significantly lower body weight, body mass index (BMI), BMI z-scores, waist circumference, body fat mass and percent body fat (%BF) compared to infrequent breakfast eaters, after adjustment for age, household income, pubertal status, eating-out and snacking practices, daily energy intakes, and daily physical activity levels. The present findings indicate that infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity. Therefore, daily breakfast consumption with healthy food choices should be encouraged in growing children and adolescents to prevent adiposity during these critical years of growth. 相似文献

Vascular smooth muscle responsiveness to nitric oxide, as assessed by nitroglycerin-induced dilation (NID), is impaired in clinical cardiovascular disease, but its relation to adiposity is unknown. We determined the relation of NID to total and abdominal adiposity in healthy adults varying widely in adiposity. In 224 men and women [age, 18-79 years; body mass index (BMI), 16.4-42.2 kg/m(2)], we measured NID (brachial artery dilation to 0.4 mg sublingual nitroglycerin), total body adiposity [BMI and percent body fat (percent BF via dual-energy X-ray absorptiometry)], and indexes of abdominal adiposity [waist circumference (WC) and waist-to-hip ratio (WHR)]. In a subgroup (n = 74), we also measured total abdominal fat (TAF), abdominal visceral fat (AVF), and subcutaneous fat (ASF) using computed tomography. Based on multiple linear regression, NID was negatively related to BMI [part correlation coefficient (r(part)) = -0.19, P = 0.004] and abdominal adiposity (WC, r(part) = -0.22; WHR, r(part) = -0.19; TAF, r(part) = -0.36; AVF, r(part) = -0.36; and ASF, r(part) = -0.30; all P ≤ 0.009) independent of sex, but only tended to be related to total percent BF (r(part) = -0.12, P = 0.07). In a subgroup of subjects with the highest compared with the lowest amount of AVF, NID was 35% lower (P = 0.003). Accounting for systolic blood pressure, HDL cholesterol, glucose, insulin resistance, adiponectin, and brachial artery diameter reduced or abolished some of the relations between NID and adiposity. In conclusion, NID is or tends to be negatively associated with measures of total adiposity (BMI and percent BF, respectively) but is consistently and more strongly negatively associated with abdominal adiposity. Adiposity may influence NID in part via other cardiovascular risk factors. 相似文献

In the 19th century, two "ecogeographical rules" were proposed hypothesizing associations of climate with mammalian body size and proportions. Data on human body weight and relative leg length support these rules; however, it is unknown whether such associations are attributable to lean tissue (the heat-producing component) or fat (energy stores). Data on weight, height, and two skinfold thickness were obtained from the literature for 137 nonindustrialized populations, providing 145 male and 115 female individual samples. A variety of indices of adiposity and lean mass were analyzed. Preliminary analyses indicated secular increases in skinfolds in men but not women, and associations of age and height with lean mass in both sexes. Decreasing annual temperature was associated with increasing body mass index (BMI), and increasing triceps but not subscapular skinfold. After adjusting for skinfolds, decreasing temperature remained associated with increasing BMI. These results indicate that colder environments favor both greater peripheral energy stores, and greater lean mass. Contrasting results for triceps and subscapular skinfolds might be due to adaptive strategies either constraining central adiposity in cold environments to reduce cardiovascular risk, or favoring central adiposity in warmer environments to maintain energetic support of the immune system. Polynesian populations were analyzed separately and contradicted all of the climate trends, indicating support for the hypothesis that they are cold-adapted despite occupying a tropical region. It is unclear whether such associations emerge through natural selection or through trans-generational and life-course plasticity. These findings nevertheless aid understanding of the wide variability in human physique and adiposity. 相似文献

BackgroundAssociation between endocan and nontraditional anthropometric indices, as distinct cardiovascular disease risk factors, has not been examined in previous studies. Endocan is a novel inflammation biomarker with its higher levels involved in cardiometabolic diseases development. Taking into consideration that obesity is an independent risk factor for many cardiometabolic diseases, we aimed to explore the relationship between endocan levels and novel anthropometric indices [i.e., body adiposity index (BAI), cardiometabolic index (CMI), a body shape index, body roundness index, conicity index, lipid accumulation product index and visceral adiposity index] and traditional ones [i.e., waist circumference, hip circumference, body mass index, waist-to-height ratio and waist-to-hip ratio] in adult population.MethodsA total of 177 participants were included. Anthropometric indices and biochemical parametres were measured.ResultsUnivariate regression analysis demonstrated positive correlations of endocan and almost all anthropometric data. To explore independent associations of endocan and anthropometric parameters, the Model which fulfilled criteria for ordinal regression testing was created. Adjusted odds for BAI given in the Model (OR=1.120, 95% CI 1.036-1.212, P=0.004), demonstrated that a rise in BAI by 1 unit increased the probability of higher endocan concentration by 12%. As well, a rise in CMI for 1 unit, increased the probability for higher endocan levels for 2.6 times (OR=2.599, 95% CI 1.006-6.712, P=0.049). A total of 20.1% of variation in endocan levels could be explained by this Model.ConclusionsNon-traditional obesity indices, BAI and CMI independently correlated with higher serum endocan levels in adult population. 相似文献

Objective: Adult growth hormone deficiency (AGHD) is associated with cardiometabolic risk factors. Given that cardiovascular disease (CVD) is an important cause of morbidity and mortality in the AGHD population, there is a need for alternative, noninvasive methods of assessing cardiometabolic risk in this population. The Chinese visceral adiposity index (CVAI) is a new marker of visceral fat dysfunction based on age, body mass index (BMI), waist circumference (WC), and metabolic parameters. CVAI is well correlated with insulin resistance (IR) and is better at predicting metabolic syndrome (MS) than BMI and WC. This study aims to examine the reliability of the lipid accumulation product (LAP), visceral adiposity index (VAI), and CVAI as cardiometabolic risk markers in AGHD patients.Methods: A total of 91 patients diagnosed with AGHD were divided into 4 groups according to CVAI quartile. We investigated the relationship between the patients' clinical and biochemical features, cardiometabolic risk assessed by cardiometabolic risk indices, the Framingham and atherosclerotic cardiovascular disease (ASCVD) risk scores, LAP, VAI, and CVAI.Results: The CVAI scores of patients were significantly higher than those of control patients. Increased CVAI significantly correlated with higher BMI, WC, waist-hip ratio (WHR), and triglycerides (TG), Framingham risk score and atherosclerotic cardiovascular disease lifetime risk score (P≤.001), with lower growth hormone (GH) and high-density lipoprotein cholesterol (HDL-C) levels (P≤.001).Conclusion: Our results suggest that CVAI may be a good marker of cardiometabolic risk in AGHD patients and could be used to diagnose CVD development and vascular accidents.Abbreviations: AGHD = adult growth hormone deficiency; ASCVD = atherosclerotic cardiovascular disease; AUROC = area under the receiver operating characteristic curve; BMI = body mass index; CVAI = Chinese visceral adiposity index; CVD = cardiovascular disease; DBP = diastolic blood pressure; GH = growth hormone; GHRT = GH replacement therapy; HDL-C = high-density lipoprotein cholesterol; IGF-1 = insulin like factor-1; IGFBP-3 = insulin like factor binding protein-3; IR = insulin resistance; LAP = lipid accumulation product; MS = metabolic syndrome; SBP = systolic blood pressure; TC = total cholesterol; TG = triglycerides; VAI = visceral adiposity index; WC = waist circumference; WHR = waist-to-hip ratio 相似文献

The pandemic of novel coronavirus disease 2019 (COVID-19) has triggered an international crisis resulting in excess morbidity and mortality with adverse societal, economic, and geopolitical consequences. Like other disease states, there are patient characteristics that impact clinical risk and determine the spectrum of severity. Obesity, or adiposity-based chronic disease, has emerged as an important risk factor for morbidity and mortality due to COVID-19. It is imperative to further stratify risk in patients with obesity to determine optimal mitigation and perhaps therapeutic preparedness strategies. We suspect that insulin resistance is an important pathophysiologic cause of poor outcomes in patients with obesity and COVID-19 independent of body mass index. This explains the association of type 2 diabetes mellitus (T2DM), hypertension (HTN), and cardiovascular disease with poor outcomes since insulin resistance is the main driver of both dysglycemia-based chronic disease and cardiometabolic-based chronic disease towards end-stage disease manifestations. Staging the severity of adiposity-related disease in a “complication-centric” manner (HTN, dyslipidemia, metabolic syndrome, T2DM, obstructive sleep apnea, etc.) among different ethnic groups in patients with COVID-19 should help predict the adverse risk of adiposity on patient health in a pragmatic and actionable manner during this pandemic. 相似文献
