Background: Skin fold thickness (SFT) at selected areas offers a simple method of subcutaneous fat assessment and provides a good estimate of obesity and body fat distribution. The triceps SFT has been shown to be one of the best and most popular sites for SFT measurement in children.Objective: To assess the body fat of school adolescents and to comparethe performance of triceps SFT with Bioelectrical impedance method in the detection of overweight (OW) and obesity (OB) among the subjectsMethods: The study was cross sectional; involving secondary schoolstudents within Sokoto metropolis. Subjects were selected by a multistagerandom sampling method. Harpenden skin fold caliper (ASSIST Creative Resources Ltd, LL13 9UG, UK) and Tanita Body fat scale (model UM-030, Tanita, UK Ltd; 2004) were used respectively to measure the triceps SFTand body fat content (%) according to the manufacturer’s instructions. Results: The mean triceps SFT values were 8.9mm (±4.7) for malesand 12.9mm (±4.6) for the females (p<0.001). Mean % BF values were8.2 ± 4.1% for the males, and 20.0 ± 6.8% for the females (p<0.001).The triceps SFT gave a prevalence of overweight of 2.5%, while that of obesity was 0.8%. With the BIA method, 2.5% of the subjects wereclassified as overweight and 1.7% as obese.Conclusion: Triceps SFT remain a fair surrogate for the assessment ofadiposity, the component of overweight that leads to pathology.Key words: Skin fold thickness, bioelectrical impedance analysis, body fat, obesity, adolescents

Determining body structure in physical culture, sports, but also in sports recreation is one of the ways to check effectiveness of certain training programs and their impact on a percentage of subcutaneous fat and fat-free components. This study was conducted on a sample of 49 kayakers and slalom canoeists (aged 19.9 ± 1.7 years), and the aim was to compare validity of methods for estimating percentage of body fat based on the skinfold measurement method in relation to the bioelectrical impedance method for application in diagnostics within a training process of slalom kayakers and slalom canoeists. The percentage of body fat was determined by methods of determining the percentage of body fat according to Siri (1961), Brozek et al. (1963), Jackson, & Pollock, (1985) and the BIA bioelectrical impedance method. After statistical procedures, correlation analysis revealed a high correlation between the methods: anthropometric methods according to Siri and Brozek, both methods with the Jackson Pollock method, while all three methods have a high level of correlation with the BIA method, while the Wilcoxon test showed that the bioelectrical impedance method had statistically significantly higher values than the method of determining the percentage of body fat according to Siri & Brozek (p <0.001), and significantly lower than the method of determining the percentage of body fat according to Jackson Pollock (p = 0.005). The research showed that in the observed sample of respondents, when it comes to one respondent, a group of respondents, respondents within one sport or an uneven sample of non-athletes, if it is not possible to use some of the more sophisticated BIA methods, a satisfactory method could be the skinfold measurement method.

Background: One of the conditions on premenopausal period is the increase in body fat, among which are caused by levels of the fluctuating estrogen hormone. Increase fat affects the body fat percentage and adipsin levels. Adipsin plays a role in the stimulation of insulin secretion by producing C3a, in which C3AR1 (C3a Receptor 1) fragments interact with beta cells to secrete insulin.Objective: The purpose of this study is to determine correlation of body fat percentage with adipsin levels on premenopause.Design: This was an analytical study with cross-sectional design. Body fat percentage was obtained by examination using Bioelectrical Impedance Analysis (BIA). Venous blood was taken at the mediana cubiti area used for serum adipsin levels. Adipsin levels were analyzed by Enzyme-linked Immunosorbent Assay (ELISA) technique.Results: The mean of body fat percentage on premenopausal was 36,18 ± 8,35%. The mean of adipsin levels on premenopausal was 117,05 ± 87,93 ng/ml. Result of Pearson test analysis got value r = 0,632 and value p = 0.0005 (p <0,05).Conclusions: There is a positive significant correlation between the percentage of body fat with adipsin levels on premenopause.

Cryolipolysis has been considered as a noninvasive alternative to surgical procedures for reducing subcutaneous fat without affecting the surrounding tissues. However, no clinical trial has investigated changes in the abdominal fat tissue by 12 weeks after cryolipolysis. Therefore, in this split-body trial, we explored whether a single session of unilateral cryolipolysis could change visceral and subcutaneous adipose tissue over a period of 12 weeks. We compared the cross-sectional areas of the abdominal adipose tissue of 15 subjects (9 women; 38.3 [10.8] years) by computed tomography before and at 12 weeks after a single treatment of cryolipolysis to the left abdomen and used the right abdomen as untreated control. In addition, we measured participants’ waist circumference, percentage of body fat (by bioelectrical impedance analysis) at baseline and at 6- and 12-weeks post-treatment. Single unilateral cryolipolysis tended to reduce the cross-sectional areas of visceral adipose tissue, by 8.4 cm2 (9.9%), the waist circumferences, and the percent body fat, by 2.8 cm2 (0.6%), overall. The cross-sectional area of visceral adipose tissues on the treated side significantly decreased, by 6.8 cm2 (15.6%; P = 0.003), and that of the untreated side tended to decrease by 1.2 cm2 (3.6%). Thus, a single unilateral session of noninvasive selective cryolipolysis can be considered as a safe and effective treatment for reduction of visceral adipose tissue over a period of 12 weeks, which should result in metabolic improvement.

Background: Research has shown that body composition is directly related to health. Altered body composition, can greatly increase the risks of conditions such as cardiovascular disease and diabetes. Bioelectrical Impedance Analysis fosters early detection of an improper balance in the body composition, which allows for earlier intervention and prevention.Methods: This was a cross sectional analysis of body composition for adults who volunteered to be screened during a Nutrition week in Kiambu County, Kenya. A total of 301 adults were included in the assessment. Body Mass Index (BMI) and Body composition (body fat %, bone mass, muscle mass, visceral fat and water %) were measured using bioelectrical impedance analysis.Results: The age of the participants ranged from 18-99 years (mean 42.19±16.57 years). Most of the participants were males (53.5%). More than half (53.2%) of the participants had a poor BMI, 37.2% had high total body fat percentage, 12.6% had excess levels of visceral fat and 26.6% had poor water hydration status. Age (OR=0.095; p value <0.001; CI 0.033-0272) and visceral fat (r=0.74; p value <0.001) were significantly associated with the BMI. Females had a significantly higher BMI (P <0.001). Visceral fat was also positively correlated with age: r=0.74; P value <0.001.Conclusions: Sex, age and BMI were important determinants of body composition. Increased physical activity, appropriate dietary practices are crucial in maintaining a healthy BMI and body composition. For timely intervention regular nutrition screening should be promoted among different populations.

Introduction/Objective. Body fat percentage (BFP) is the most reliable indicator of a nutritional status. For clinical practice it is important but scarcely investigated whether to exclusively use contemporary methods of BFP measurement, or classic anthropometric methods are also reliable. The aim was to investigate the correlation between the results of BFP measuring using a contemporary method of bioimpedance (Bio) and classic methods of skin fold thickness (SFT) and body mass index (BMI). Method. There were 279 patients of the Dietetic Counseling Center of the Institute for Public Health in Nis who were included in the research during 2015. Body fat percentage was determined using three classic anthropometric methods of ST over the triceps, and the scapula and BMI. Apparatus OMRON BF 302 was used for BFP measuring with bioimpedance method. Results. Using a one factorial analysis of variance we found a statistically significant difference between the mean values of the BFP obtained with bioimpedance and with anthropometric methods (F = 24.19, p < 0.05). Post hoc analysis revealed a statistically significant difference between the BFP determined with bioimpedance and SFT over the triceps and the scapula, while the anthropometric method based on BMI gave the results similar to those from bioimpedance. Conclusion. We show that the most reliable anthropometric method of determination of BFP is that based on BMI, as its results correlate best with those obtained with a contemporary method of bioimpedance.

Aging involves both nutritional and physiological changes, reducing fat-free mass (FFM) and increasing body fat, both of which are associated with physical weakness, unfitness and morbidity among the elderly. This study was undertaken to analyze the cross-validity of bioelectrical impedance equations for the prediction of fat-free mass (FFM) in elderly Brazilians. A cross-sectional population-based study, was performed in Florianópolis, Santa Catarina, Brazil, 2006. The study sample comprised 60 men and 120 women, aged 60 to 81. The dual energy X-ray absorptiometry (DEXA) served as gold standard. Predicted %BF and FFM were obtained from various anthropometric equations and bioelectric impedance. The cross-validation criteria suggested by Lohman and Bland-Altman plots of differences against the mean were used. The body mass index of the sample ranged from 18.4 to 39.3 kg/m². Mean percent body fat was 23.1 ± 5.8% in men and 37.3 ± 6.9% in women (range: 6 to 51.4%). In men, the equations of Kyle et al. (2001), Dey et al. (2003) and Sun et al. (2003) did not differ significantly from the DEXA measurement, with a constant error (CE) of 0.7 to 2.5 kg. In contrast, among women only the equations of Kyle et al. (2001) and Dey et al. (2003) were found to be valid (CE: 0.3 to 2.7 kg). The bioelectrical impedance equations validated in this study can be used in the Brazilian elderly population.

 The role of nutrition in the life cycle is very important. If there is a problem with malnutrition, this is a sign that you are at risk of suffering from chronic disease. Measurement of nutritional status and body fat percentage is important as an initial screening to prevent the risk of chronic disease. This study aims to describe the performance of the nutritional status and body fat percentage of new student STIKes Baiturrahim 2020. This study used a cross-sectional study. The research was conducted at STIKes Baiturrahim Jambi in September 2019. The number of respondents was 148 people. The data used are the characteristics of the respondents (age, sex, body weight, and height) and the percent of body fat obtained from measurement of Bioelectrical Impedance Analysis (BIA). The results showed that most of them had normal nutritional status (64,2%) and body fat percentage was classified as normal (41,9%). It is recommended that students maintain normal nutritional status and body fat percentage and also always monitoring the body weight to prevent chronic disease

AbstractBioelectrical impedance analysis (BIA) is used to analyze human body composition by applying a small alternating current through the body and measuring the impedance. The smaller the electrode of a BIA device, the larger the impedance measurement error due to the contact resistance between the electrode and human skin. Therefore, most commercial BIA devices utilize electrodes that are large enough (i.e., 4 × 1400 mm2) to counteract the contact resistance effect. We propose a novel method of compensating for contact resistance by performing 4-point and 2-point measurements alternately such that body impedance can be accurately estimated even with considerably smaller electrodes (outer electrodes: 68 mm2; inner electrodes: 128 mm2). Additionally, we report the use of a wrist-wearable BIA device with single-finger contact measurement and clinical test results from 203 participants at Seoul St. Mary’s Hospital. The correlation coefficient and standard error of estimate of percentage body fat were 0.899 and 3.76%, respectively, in comparison with dual-energy X-ray absorptiometry. This result exceeds the performance level of the commercial upper-body portable body fat analyzer (Omron HBF-306). With a measurement time of 7 s, this sensor technology is expected to provide a new possibility of a wearable bioelectrical impedance analyzer, toward obesity management.
