Background: Among adults, obesity has been positively related to bone mineral density. However, recent findings have pointed out that abdominal obesity could be negatively related to bone density. The above mentioned relationship is not clear among pediatric populations. Therefore, this cross-sectional study analyzed the relationship between thickness of abdominal adipose tissue and bone mineral variables in sedentary obese children and adolescents.Methods: One hundred and seventy five obese children and adolescents (83 male and 92 female) with ages ranging from 6 to 16 years-old were analyzed. Bone mineral content and density were estimated by dual-energy X-ray absorptiometry and ultrasound equipment which estimated the thickness of the abdominal adipose tissue. Pubertal stage was self-reported by the participants.Results: The mean age was 11.1 (SD = 2.6). Thickness of the abdominal adipose tissue was negatively related to bone mineral density (r = -0.17 [r95%CI: -0.03;-0.32]), independent of gender, pubertal stage and other confounders (β = -0.134 ± 0.042 [β95%CI: -0.217; -0.050]).Conclusions: In sedentary obese children and adolescents abdominal obesity is negatively related to bone mineral density, suggesting a potential link between abdominal obesity and osteoporosis. © 2013 Júnior et al.; licensee BioMed Central Ltd.

Study Design: Prospective study Objective: To evaluate the effect of a protocol of concurrent training lasting 16 weeks on risk factors for the accumulation of hepatic fat in obese youth. Methods: 38 obese children and adolescents of both sexes, between 12 and 15 years old. The obesity was attested by the percentage of body fat, which was estimated by dual-energy X-ray absorptiometry (DEXA). Additionally, the amount of fat located in the trunk (kg) was estimated too. Before and after the intervention, the youths underwent biochemical blood tests (fasting complete lipid profile [mg / dL]) and ultrasonography of the liver (right size Wolves [LD cm] and left [LE in cm]). The intervention consisted of concurrent training (strength training [30 minutes] and endurance training [30 minutes]) with three sessions per week, totaling 180 minutes a week, for ten weeks. Statistical analysis was made by the test t of Student for paired data using SPSS software (17.0) and significance statistical fixed at p <5%. Results: After the intervention, significant improvements were observed in the percentage of total fat (PRE: 45.1 ± 5.3 and POST: 41.7 ± 5.6, p = 0.001) and in the trunk region (PRE: 46, 5 ± 5.6 and POST: 42.9 ± 6.3, p = 0.001).

OBJECTIVE: to describe the frequency and the factors associated with cholelithiasis in obese adolescents. METHODS: this was a cross-sectional descriptive study performed with the adolescents between 10 and 19 years of age treated at the Child and Adolescent Obesity Outpatient Clinic from May to December of 2011. Obesity was defined as body mass index (BMI) > P97, and overweight as BMI > P85, for age and gender, according to the 2007 World Health Organization reference. A questionnaire concerning the presence of signs and symptoms, such as abdominal pain, nausea, vomiting, and intolerance to fat, was administered. Patients were asked about how many kilograms they had lost and in how much time. Laboratory parameters were: triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels. Cholelithiasis and hepatic steatosis were diagnosed by ultrasonography. RESULTS: cholelithiasis was diagnosed in 6.1% (4/66) of the obese adolescents, most of whom were female (3/4); hepatic steatosis was identified in 21.2% (14/66). Intolerance to dietary fat was reported by all patients with cholelithiasis (4/4) and by 17.7% (11/62) of the group without cholelithiasis (p = 0.001). The average weight loss was 6.0 ± 2.9 kg in the patients with cholelithiasis and 3.2 ± 4.8 kg in the group without cholelithiasis (p = 0.04). However...

Background: Venous insufficiency is a very prevalent disease. Some decades ago a group of patients was identified that had symptoms of venous insufficiency, but no visible anatomic abnormalities. Studies showed that this subset had reduced venous tone, and their condition became known as hypotonic phlebopathy. Objective: To investigate prevalence, age group and variations in body mass index (BMI) among patients with hypotonic phlebopathy. Methodology: A total of 1,960 limbs were examined in 1,017 patients who had been referred for complaints compatible with venous insufficiency. Patients with BMI ≥ 30 were defined as obese. The patients were examined using color Doppler ultrasonography to detect presence or absence of reflux in veins of the lower limbs and were then distributed into two groups as follows: patients with CEAP ≤ 1 and no reflux, diagnosed with hypotonic phlebopathy; or patients with CEAP ≥ 2 and reflux. Results: The study sample comprised 89.7% women and 10.3% men with a mean age of 44.9 years. Hypotonic phlebopathy was more common among the women (p = 0.0001). Obese women were more likely than women who were not obese to have venous symptom etiology involving trunk lesions (p = 0.0017). Among the men...

Objective To compare the endometrial echo values obtained by transvaginal ultrasonography with the body mass index of postmenopausal patients; to verify if there is higher prevalence of endometrial thickening in women with body mass index ≥30. Methods This is an analytical and cross-sectional study that evaluated 294 patients. Postmenopausal women were included, and those on hormone therapy were excluded. The variables evaluated were body mass index (considering obesity if >30), number of pregnancies, years since menopause, and age. These variables were correlated with endometrial echography. Results There was a statistically significant correlation between overweight and obese patients and increased endometrial thickness (p=0.0236). The correlation between age and endometrial echo was negative and statistically significant, that is, the older the woman, the lower the endometrial thickness (p=0.0478). Pregnancies and years since menopause showed no statistical significance in relation to endometrial echo, with p=0.0614 and p=0.115, respectively. Conclusion There was positive and significant correlation between body mass index ≥30 and endometrial thickeness.

Carotid intima-media-thickness (cIMT) and carotid distensibility (distensibility), structural and functional properties of carotid arteries respectively, are early markers, as well as strong predictors of cardiovascular disease (CVD). The characteristic of these two parameters in individuals with BMI>40.0 kg/m2 (Class III obesity), however, are largely unknown. The present study was designed to document cIMT and distensibility in this population and to relate these to other factors with established association with CVD in obesity. The study included 96 subjects (65 with BMI>40.0 kg/m2 and 31, age- and gender-matched, with BMI of 18.5 to 30.0 kg/m2). cIMT and distensibility were measured by non-invasive high resolution ultrasonography, circulatory CD133+/KDR+ angiogenic cells and endothelial microparticles (EMP) by flow cytometry, and plasma levels of adipokines, growth factors and cytokines by Luminex immunoassay kits. The study results demonstrated increased cIMT (0.62±0.11 mm vs. 0.54±0.08 mm, P = 0.0002) and reduced distensibility (22.52±10.79 10−3kpa−1 vs. 29.91±12.37 10−3kpa−1, P<0.05) in individuals with BMI>40.0 kg/m2. Both cIMT and distensibility were significantly associated with traditional CVD risk factors...

Objectives. This study aims to analysis the relationship between c.-492T>C polymorphism in APOA2 gene and the risk for obesity in a sample of Egyptian adolescents and investigates its effect on body fat distribution and lipid metabolism. Material and Methods. A descriptive, cross-sectional study was conducted on 303 adolescents. They were 196 obese and 107 nonobese, aged 16–19 years old. Variables examined included body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), systolic and diastolic blood pressure (BP), body fat percentage (BF%), abdominal visceral fat layer, and dietary intake. Abdominal visceral fat thickness was determined by ultrasonography. The polymorphism in the APOA2 c.-492T>C was analyzed by PCR amplification. Results. Genotype frequencies were in Hardy-Weinberg equilibrium. The frequency of the mutant C allele was significantly higher in obese cases compared to nonobese. After multivariate adjustment, waist, BF% and visceral adipose layer, food consumption, and HDL-C were significantly higher in homozygous allele CC carriers than TT+TC carriers. Conclusions. Homozygous individuals for the C allele had higher obesity risk than carriers of the T allele and had elevated levels of visceral adipose tissue and serum HDL-C. Moreover...

This study characterizes the effect of an excess-calorie, high-fat, high-cholesterol, high-fructose diet on metabolic parameters and reproductive function in female Ossabaw minipigs. Cycling sows were fed a hypercaloric, high-fat, high-cholesterol, and high-fructose diet (obese, n = 4) or a control diet (control, n = 5) for 13 mo. During the final 4 mo, ovarian ultrasonography was done, blood was collected, and weights and measures were taken. Pigs then underwent ovarian stimulation. Cycle length and androstenedione, total testosterone, progesterone, estradiol, follicle-stimulating hormone, luteinizing hormone, insulin, fructosamine, lipid, and glucose levels were measured. In addition, adipose tissue aromatase gene expression was assessed. As compared with control pigs, obese pigs were hyperglycemic and hyperinsulinemic; had elevated total cholesterol, triglyceride, and leptin levels, and demonstrated abdominal adiposity. Visceral adipose tissue of obese pigs, as compared with control pigs, showed increased aromatase gene expression. Obese pigs had longer estrous cycles, higher serum androstenedione, and higher luteal phase serum luteinizing hormone, compared with control pigs. During the luteal phase, obese pigs had more medium, ovulatory...

The accumulation of fat in the pancreatic gland has been referred to using various synonyms, such as pancreatic lipomatosis, fatty replacement, fatty infiltration, fatty pancreas, lipomatous pseudohypertrophy, non-alcoholic fatty pancreatic disease and pancreatic steatosis We believe that pancreatic steatosis is the best description of fat accumulation in the pancreatic gland without fat replacement, and this term also describes the possibility that the fat accumulation is a reversible process. A review of the existing literature was carried out, and it was found that there was notable evidence from both the pathological and the imaging point of view that pancreatic steatosis is an increasing problem due to the increasing incidence of obesity. The conclusion was that pancreatic steatosis was easily detectable using modern imaging techniques, such as ultrasonography, endoscopic ultrasonography, computed tomography and magnetic resonance imaging. Pancreatic steatosis was not due to the presence of diabetes mellitus but was highly associated with the metabolic syndrome. The possible presence of steatopancreatitis should be better evaluated, especially regarding the inflammatory cascade, and additional studies are needed which are capable of assessing whether non-alcoholic steatopancreatitis really exists as does non-alcoholic steatohepatitis. Finally...

This study was done to evaluate the efficacy of health check-ups in children in detecting metabolic syndrome and non-alcoholic fatty liver disease (NAFLD) by comparing the pediatric health promotion center with the pediatric obesity clinic. Children who visited a pediatric health promotion center (n=218) or a pediatric obesity clinic (n=178) were included. Anthropometric data, blood pressure, laboratory tests, and abdominal ultrasonography were evaluated. Two different criteria were applied to diagnose metabolic syndrome. The prevalence of metabolic syndrome in the 2 units was 3.2%-3.7% in a pediatric health promotion center and 23%-33.2% in a pediatric obesity clinic. Significant differences were observed in the prevalence of each component of metabolic syndrome between the 2 units including abdominal adiposity, blood pressure, serum triglycerides, and fasting blood glucose (P<0.05). The prevalence of NAFLD was 8.7% and 71.9% in the 2 units according to liver enzymes and 5.9% and 61.8% according to ultrasonography (P<0.05). The prevalence of metabolic syndrome and NAFLD was higher among patients visiting the obesity clinic targeting obese children than that among patients visiting the health promotion center offering routine check-ups. An obesity-oriented approach is required to prevent obesity-related health problems in children.

Obesity increases linearly with age and is associated with impaired vascular endothelial function and increased risk for cardiovascular disease. Mineralocorticoid receptors (MR) contribute to impaired vascular endothelial function in cardiovascular disease; however, their role in uncomplicated human obesity is unknown. Because plasma aldosterone levels are elevated in obesity and adipocytes may be a source of aldosterone, we hypothesized that MR modulate vascular endothelial function in older adults in an adiposity-dependent manner. To test this hypothesis, we administered MR blockade (Eplerenone; 100 mg/day) for 1 month in a balanced, randomized, double-blind, placebo-controlled, crossover study to 22 older adults (10 men, 55–79 years) varying widely in adiposity (body mass index: 20–45 kg/m2) but who were free from overt cardiovascular disease. We evaluated vascular endothelial function (brachial artery flow-mediated dilation [FMD] via ultrasonography) and oxidative stress (plasma F2-isoprostanes and vascular endothelial cell protein expression of nitrotyrosine and NADPH oxidase p47phox) during placebo and MR blockade. In the whole group, oxidative stress (P>0.05) and FMD did not change with MR blockade (6.39±0.67 vs. 6.23±0.73 %...

The objective of this experiment was to evaluate the histology of livers of castrated bitches during sequential periods of weight gain and loss, through analysis of samples obtained by ultrasound guided biopsies. The experimental groups were composed by 30 bitches submitted to overweight by using of hypercaloric ration, from these animals were selected 14 to be submitted to two differents weight loss programs with seven receiving hypocaloric ration and seven receiving normocaloric ration. Periodic ultrasonographic analysis was employed to evaluate liver structure during the initial, obesity and weight loss stages, and revealed that none of the animals displayed altered images and no lesions at any stages. Histological examination revealed that no animals showed (0%) fibrosis or fat degeneration, 13 animals (92,8%) presented mild inflammation and one animal (7,2%) had severe inflammation. Nine animals (64,2%) did not have any kind of necrosis, four animals (28,5%) had mild necrosis and one animal (7,2%) had moderate necrosis. At the end of obesity stage, no animal showed fibrosis or fat degeneration and all 14 animals had mild inflammation. Ten dogs (71,5%) showed no signs of necrosis and four animals (28,5%) with light necrosis. Finally...

Given the difficulty of accurately diagnosing the body condition in dogs, and the difference in results between the two available methods, the aim of this study was to compare four different methods of measuring the body condition of dogs. Such methods are: body condition score; canine body mass index; morphometric measurements; and ultrasound. The study also aimed at verifying the equivalence of these methods, and their extrapolation to total body fat. In addition to verifying the relations between body condition and castration, sex, age, diet, we sought to identify possible traits that interfere with the evaluation by any of the methods, as well as verify the possibility of assigning cutoff points for the ultrasound method. We evaluated 80 dogs from the Veterinary Hospital of the Universidade Federal de Lavras, using the four abovementioned measurement methods. The methods had significant relations, with strong association between them, with the exception of the ultrasound method. We observed good relation between the methods for extrapolating body fat percentage, also with the exception of the ultrasound method. We also observed relation between higher rates of obesity and overweight in females, castrated dogs, elderly and animals fed the basic feed...

peer-reviewed; Obesity is a global epidemic and is defined as excess fat accumulation to the extent that health may be impaired (WHO 2000). However, body mass index (BMI), the metric used to quantify obesity, does not adequately represent fat tissue mass (FTM). A metric that quantifies obesity according to FTM is required. Methods that accurately measure total and segmental FTM and are suitable for use in large scale studies are necessary. Using dual energy x-ray absorptiometry (DXA) as the reference method of measurement, this thesis documents the body composition, specifically FTM and its distribution, of 1136 Irish adults aged 18-81 years. Fat tissue mass index (FTMI, kg/m2) was chosen as the most appropriate metric to define ‘fat obesity’ and to compare the difference in total body fat according to age and sex. Reference FTMI values were derived from young adult (YA) z-scores. FTMI was found to increase with age in men and women, as did the proportion of FTM deposited abdominally. 40% of men and 45% of women defined as ‘fat obese’ by FTMI were not ‘obese’ by BMI. Compared to DXA, the accuracy of the prediction methods i.e. bioelectrical impedance analysis (BIA), anthropometry and ultrasonography, for the measurement of total and/or segmental body fat has been established. Prediction equations derived from site-specific skinfold and girth measures accurately estimated % body fat in men (r=0.91...

OBJETIVO: comparar os fatores ecográficos de risco cardiovascular em pacientes obesas e não obesas, com síndrome dos ovários micropolicísticos (SOMP). MÉTODOS: foram incluídas 30 pacientes obesas com SOMP (Índice de massa corporal, IMC>30 kg/m²) e 60 não obesas (IMC<30 kg/m²), com idade entre 18 e 35 anos neste estudo transversal. Foram avaliados: a dilatação mediada por fluxo (DMF) da artéria braquial, espessura íntima-média da artéria carótida (IMT), o índice de rigidez da artéria carótida (β), as medidas antropométricas, pressão sanguínea sistólica (PAS) e diastólica (PAD). As mulheres estavam sem nenhum tratamento prévio e nenhuma delas apresentava qualquer comorbidade (além da SOMP e/ou da obesidade).Na análise estatística, foram utilizados os testes t não-pareado ou de Mann-Whitney. RESULTADOS: as pacientes obesas com SOMP apresentaram maior peso em relação às não obesas (92,1±11,7 kg versus 61,4±10,7 kg, p<0,0001), bem como a medida da cintura que também, foi mais elevada nas pacientes obesas (105,0±10,4 cm versus 78,5±9,8 cm, p<0,0001). A PAS das pacientes obesas foi superior quando comparadas às não obesas (126,1±10,9 mmHg versus 115,8±9,0 mmHg, p<0,0001) e a IMT também foi maior nas obesas (0...

In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS) underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity...

DOI: http://dx.doi.org/10.5007/1980-0037.2012v14n3p333The currently available methods for evaluation of visceral obesity have limitations, making them impractical for evaluating large numbers of individuals. This study aimed to develop and validate prediction equations to estimate the area of visceral adipose tissue in young women. The sample included 64 women aged 19 to 36 years. The following variables were evaluated: visceral fat volume (VFV) measured by ultrasound; body mass index (BMI); waist circumference; waist-to-height ratio (WHtR); waist-to-hip ratio (WHR); conicity index; lipid profile; and fasting plasma glucose (FPG). The women were divided into two groups for development (n=48) and validation (n=16) of equations. Three equations were proposed and validated to estimate VFV: Equation 1: VFV = - 31.888 + (4.044 x BMI); Equation 2: VFV = - 51.891 + (248.018 * WHtR); and Equation 3: VFV = - 130.941 + (198.673 x WHtR) + (1.185 x FPG); with a predictive power of 34%, 24%, and 45% respectively. There was no statistically significant difference between VFV values assessed by ultrasound and estimated by the prediction equations in the validation group. The proposed equations can be used to calculate VFV in young women when imaging tests are not available...
