SummaryThis study examined the relation between waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHpR), waist-to-height ratio (WHtR) and triceps skin-fold thickness and percentage body fat in young Syrian men. The aim was to develop equations that can use these anthropometric characteristics to estimate percentage body fat in this group of subjects. A total of 2470 healthy Syrian men aged 18–19 years were enrolled in the study in 2010–2011. The anthropometric characteristics of all subjects were measured. The percentage body fat of 213 of the subjects was determined using the deuterium dilution (DD) technique as a reference method. The validity of using WC, HC, WHpR and WHtR to calculate percentage body fat, in comparison with the reference method (DD technique), was assessed by calculating biases and limits of agreement. The estimates of percentage body fat using ‘WC’ and ‘WC with triceps skin-fold’ measurements ranged from 13.00±5.56% to 14.55±8.63%, and were lower than those determined using the reference method (21.32±6.42%). A better prediction equation is proposed for young adults, based on a multiple linear regression model using WC, HC and WHtR.

Objective In order to find a scientific and effective way to lose weight, the effect of kickboxing exercise was studied by the method of experiment. Through research, it is found that kickboxing can effectively change the body shape and body composition of the human body and achieve a better weight loss effect. This study further enriches and improves the theory of exercise and fitness, which can provide scientific guidance for obese children and adolescents to lose weight and provide a good reference for obesity of other age groups and special populations.  Methods In this paper, 20 students of 12~14 years old in the summer class of Wuhan diet training camp were selected as the subjects. Through the test of height and weight, the 20 subjects of drug induced obesity or non secondary obesity were selected by BMI as the main basis, including 8 girls and 12 boys. kickboxing training time is 8 weeks, 3 times a week, each class 60 minutes，from warming up, basically, relax three parts. In order to study the effects of kickboxing on body composition of obese people, skin fold thickness, girth and body fat were monitored and tested.  Results After 8 weeks of kickboxing exercise, there was a significant difference in the thickness of the upper arm skin fold of the boys P < 0.05, and the thickness of the skin fold of the lower scapula was P < 0.01, but the changes in the abdomen were not obvious. While the skin thickness of the upper arm and the abdominal skin fold were P < 0.05, and there was no significant difference in the skin fold thickness of the scapula. Male hip circumference P < 0.05 had a very significant change, chest circumference, waist circumference and waist hip ratio P > 0.05 did not change significantly. The waist circumference and waist hip ratio were significantly changed, but there was no significant change in chest circumference and hip circumference. After exercise, the changes in fat content, muscle weight and BMI were the most significant. Girls' weight, fat content, body fat percentage and BMI were the most significant changes, followed by a slight change in muscle weight. Conclusions From the qualitative point of view, it can be concluded that the practice of kickboxing exercises can effectively develop flexibility, balance, coordination and so on. It has a significant effect on improving human posture and sports ability. From a quantitative point of view, aerobics can also reduce fat content, increase muscle weight, make the percentage of BMI, body fat change significantly, and have a significant impact on maintaining muscle content and muscle / weight ratio and laying a solid foundation for future exercise. It can be concluded that kickboxing is a suitable exercise for obese people to lose weight.

Background: Studies in India shown high body fat indices were strongly associated with hypertension in Indian children, but such studies mostly not done in southern states of India. So, authors include children in Tamilnadu measure body fat indices and blood pressure to find which body fat index correlates closely with hypertension.Methods: Standing height was measured using stadiometer. Weight was measured using electronic scale. WC measured in standing position, by a stretch resistant.  WC above 90th centile will be considered as Adipose. Waist to height ratio optimal cut-off value is 0.44 for children. TSFT recorded using Harpenden caliper, on the non-dominant upper arm. Wrist circumference measured using stretch resistant tape.Results: In this study 2000 children were participated. More hypertensives are seen in 10 to 12 years(62) and 16 to 18 years(31).Increased weight correlated with hypertension. Study indicates waist circumference is significantly correlated with systolic BP p<0.003, diastolic BP p<0.000. This study shows significant correlation p<0.003 for systolic and p<0.000 for diastolic BP with triceps skin fold thickness estimation. In multivariate analysis with systolic blood pressure and diastolic blood pressure shows very strong correlation with waist circumference, waist to height ratio and triceps skin fold thickness.Conclusions: In this study we investigate the correlation between body fat indices and blood pressure correlation was statistically analyzed which shows that waist circumference, waist to height ratio and triceps skin fold thickness were strongly correlated with systolic and diastolic BP.

Introduction. Cystatin C (CysC) is a glomerular filtration rate (GFR) marker affected by GFR and obesity. Because percentage body fat (%BF) distribution is affected by ethnicity, different measures of %BF may improve CysC prediction. This study aims to create multivariate models that predict serum CysC and determine which %BF metric gives the best prediction. Methods. Serum CysC was measured by nephelometric assay. We estimated %BF by considering weight, body mass index, waist-hip ratio, triceps skin fold, bioimpedance, and Deurenberg and Yap %BF equations. A base multivariate model for CysC was created with a %BF metric added in turn. The best model is considered by comparing P values, R2, Akaike information criterion (AIC), and Bayesian information criterion (BIC). Results. There were 335 participants. Mean serum CysC and creatinine were 1.27 mg/L and 1.44 mg/dL, respectively. Variables for the base model were age, gender, ethnicity, creatinine, serum urea, c-reactive protein, log GFR, and serum albumin. %BF had a positive correlation with CysC. The best model for predicting CysC included bioimpedance-derived %BF (P=0.0011), with the highest R2 (0.917) and the lowest AIC and BIC (−371, −323). Conclusion. Obesity is associated with CysC, and the best predictive model for CysC includes bioimpedance-derived %BF.

1. Jaundice is a marker of severity of liver disease, as well as a consequence of decompensation. Yellow discolouration is not usually seen until the serum bilirubin is >40μmol/L (twice the upper limit of normal), although the earliest signs of jaundice can be detected in the periphery of the conjunctivae, or in the buccal mucosa. Remember, there are other causes of jaundice in liver disease, such as Zieve’s syndrome (haemolysis and hyperlipidaemia in alcohol misuse), or biliary obstruction. 2. Cachexia can be established by demonstrating muscle and fat loss. Wasting of the temporalis muscle is an early sign of generalized muscle atrophy. A reduced triceps skin-fold thickness is a marker of loss of fat stores. This can be demonstrated by palpating for redundant skin over the triceps area between your thumb and forefingers. 3. Anaemia is most reliably demonstrated by looking for conjunctival pallor. This is thought to be more sensitive than looking for pallor of skin creases, nails, or other mucosal membranes. If there is no evidence of anaemia, it is an important negative to mention to the examiner. The principal causes of anaemia in chronic liver disease are blood loss from portal hypertensive gastropathy, alcohol excess causing bone marrow suppression and poor nutrition. 4. Other gastrointestinal (GI) causes of clubbing include inflammatory bowel disease (IBD), coeliac disease, GI lymphoma and rare causes of malabsorption such as tropical sprue and Whipple’s disease. 5. Leuconychia is a non-specific finding which is associated with hypoalbuminaemia as well as other conditions such as heart failure, renal disease, Hodgkin’s lymphoma (HL) and diabetes mellitus (see Case 8—Nephrotic Syndrome). 6. Palmar erythema reflects the vasodilated state of cirrhosis. Other causes of palmar erythema include hypercapnoea, rheumatoid arthritis, thyrotoxicosis, pregnancy, fever, and exercise. 7. Spider naevi are vascular lesions, with a central arteriole that supplies smaller surrounding vessels. Generally, the number and size correlate with the severity of liver disease, although they may occur in normal individuals and pregnancy. Spider naevi, palmar erythema, gynaecomastia, and loss of body hair are thought to be the consequence of altered sex hormone metabolism, and an increase in the oestradiol:free testosterone ratio.

Body mass index (BMI) acts as a casual factor for developing many diseases such as cardiovascular, breast cancer, heart, diabetes etc. The article presents the impacts of BMI on gestational diabetes Pima Indian heritage women with at least 21 years old. It is established here that mean BMI is larger for gestational diabetes mellitus (GDM) women (P=0.0007) than normal. Mean BMI is directly linked with triceps skin fold thickness (TSFT) (P<0.0001), and it is not related with age (P=0.5185), while it is inversely linked with their joint interaction effect TSFT*Age (P=0.0023). In addition, mean BMI is partially inversely linked with insulin (P=0.1813), and it is partially directly linked with diabetes pedigree function (PDF) (P=0.1601). Variance of BMI is larger for normal women (P<0.0001) than GDM women. It is inversely linked with glucose (P<0.0001), and it is not associated with the number of pregnancies (NOP) (P=0.5494), while it is directly linked with their joint interaction effect Glucose*NOP (P=0.0434). Mean and variance of BMI show many complex impacts on GDM women. Gestational women must care on BMI along with TSFT and glucose levels.
