This investigation compared the percentage of body fat obtained using the bioelectrical impedance technique and the anthropometric technique on a black pediatric population consisting of 196 subjects, 93 girls and 103 boys, ages 5-11 years. Subjects were measured utilizing the Bioelectrical Impedance Analyzer-103 (RJL Systems, Inc.). In order to simulate a realistic school environment, protocol was deliberately not followed. Anthropometric measurements were obtained at two sites: triceps and medial calf. The anthropometric and BIA percentages of body fat were compared using the Pearson product-moment coefficient or correlation and an ANOVA. The overall relationship between the groups was .809. Use of the BIA appears to lead to an overestimation of fatness in black children.

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.

Nutritional anthropometry is a widely accepted and commonly used technique to determine health risks associated with malnutrition. However the uses of anthropometry in large epidemiological studies have certain limitations such as some degree of measurement error, lack of trained manpower and laborious measurement process. Bioelectrical Impedance Analysis (BIA) is recognized as an alternative tool to anthropometry and extensively studied its suitability to measure the nutritional status of the individuals in field settings. Hence, a cross sectional study was undertaken to assess the nutritional status of college going adolescent girls (18+ years of age) by using Bioelectrical Impedance Analyzer. Total of one hundred ninety three in-house students were selected for this study based on random sampling method. Socioeconomic background of the selected participants were collected through personal interview. KaradaScan Body Composition Monitor with Scale (Model HBF-362, Omron Healthcare Company Limited, Kyoto, Japan) was used to determine the body composition of the participants. The results showed that majority of the participants were Hindu (>90%), belong to Backward and Scheduled Caste community, father work as a coolie and earn Rs. 25,000-50,000/- per annum. Based on Body Mass Index (BMI) cut off point, 50% of the participants were normal (BMI 18.5 – 24.9 kg/m2), 40% of them were underweight (BMI<18.5 kg/m2) and the remaining were overweight (BMI 25.0–30.0 kg/m2). Body composition analysis revealed that skeletal muscle and body fat content were 26.16±1.38 (ranged from 20 to 30%) and 29.02±3.56 % (ranged between 20 and 38%) of the total body weight respectively. Visceral and subcutaneous fat content were 2.70±1.65 and 22.38±4.38% of total body fat respectively. The findings indicate that the prevalence of undernutrition is higher among college going adolescent girls than over nutrition due to poor economic situation, faulty diet habits, peer pressure on body image, mental stress, lack of physical activity etc.

Abstract: Physical activity is a body movement produced by skeletal muscles which requires energy. Lack of physical activity has a negative impact, one of which is an increase in body fat percentage above the normal threshold or often associated with obesity. Zumba is one of the popular aerobic exercises in the form of dancing. This study was aimed to compare the percentage of body fat before and after undertaking Zumba exercise in adult woman. This was an experimental field study with the one group pretest-posttest design. Samples were obtained by using total sampling technique. Zumba exercise was undertaken for 4 weeks, 3 times a week for 60 minutes. The percentage of body fat was measured by using an instrument based on Bioelectrical Impedance Analysis. Data were analyzed with the Wilcoxon Signed Rank test. The results showed that l6 subjects were involved in this study. The mean percentage of body fat percentage before Zumba exercise was 39.300% (SD±8.1041) meanwhile the mean percentage of body fat percentage after Zumba exercise was 39.031% (SD±7.9232). The statistical analysis to compare the body fat percentage before and after doing Zumba exercise obtained a P value of 0.065. Conclusion: There was no significant difference in body fat percentage before and after undertaking 4-week Zumba exercise among adult females.Keywords: body fat percentage, Zumba exercise Abstrak: Aktivitas fisik merupakan gerakan tubuh yang dihasilkan otot rangka yang memer-lukan energi. Kurangnya aktivitas fisik seperti olahraga memiliki dampak negatif, salah satunya peningkatan persentase lemak tubuh di atas ambang normal atau obesitas. Olahraga yang sedang popular belakangan ini ialah senam Zumba, yaitu latihan aerobik dalam bentuk tarian. Penelitian ini bertujuan untuk mengetahui perbandingan persentase lemak tubuh sebelum dan setelah melakukan senam zumba pada wanita dewasa. Jenis penelitian ialah eksperimental lapangan dengan desain one group pretest-posttest. Teknik sampling yang digunakan ialah total sampling. Senam Zumba dilakukan selama 4 minggu dengan frekuensi 3 kali seminggu yang berdurasi 60 menit. Persentase lemak tubuh diukur menggunakan alat berbasis bioelectrical impedance analysis. Data penelitian dianalisis dengan uji Wilcoxon Signed Rank Test. Hasil penelitian mendapatkan 16 subjek. Rerata persentase lemak tubuh sebelum senam Zumba yaitu 39,300% (SD±8,1041). Rerata persentase lemak tubuh setelah senam Zumba yaitu 39,031% (SD±7,9232). Hasil uji perbandingan persentase lemak tubuh sebelum dan setelah melakukan senam zumba menunjukkan nilai P=0,065. Simpulan: Tidak terdapat perbedaan bermakna dari persentase lemak tubuh sebelum dan setelah melakukan senam zumba selama 4 minggu pada wanita dewasa.Kata kunci: persentase lemak tubuh, senam Zumba
