body fat measurement in adolescents comparison of Skinfold Thickness equations with dual energy x ray absorptiometry
European Journal of Clinical Nutrition, 2005Co-Authors: Gerardo Rodríguez, M G Blay, V A Blay, A Sarria, Luis A Moreno, Jesús Fleta, M BuenoAbstract:To compare the most commonly used equations to predict body fatness from Skinfold Thickness, in male and female adolescents, with dual-energy X-ray absorptiometry (DXA) as a reference method of fatness measurement. Cross-sectional nutrition survey. General adolescent population from Zaragoza (Spain). A total of 238 Caucasian adolescents (167 females and 113 males), aged 13.0–17.9 y, were recruited from 15 school groups in 11 public and private schools. The percentage fat mass (%FM) was calculated by using Skinfold-Thickness equations. Predicted %FM was compared with the reference %FM values, measured by DXA. The lack of agreement between methods was assessed by calculating the bias and its 95% limits of agreement. Most equations did not demonstrate good agreement compared with DXA. However, in male adolescents, Slaughter et al equations showed relative biases that were not dependent on body fatness and the limits of agreement were narrower than those obtained from the rest of equations. In females, Brook's equation showed nonsignificant differences against DXA and the narrowest 95% limits of agreement. Only biases from Brook and Slaughter et al equations were not dependent on body fatness in female adolescents. Accuracy of most of the Skinfold-Thickness equations for assessment of %FM in adolescents was poor at the individual level. Nevertheless, to predict %FM when a relative index of fatness is required in field or clinical studies, Slaughter et al equations may be used in adolescents from both sexes and the Brook equation in female adolescents.

Skinfold Thickness measurements are better predictors of body fat percentage than body mass index in male spanish children and adolescents
European Journal of Clinical Nutrition, 1998Co-Authors: A Sarria, Luis A Moreno, Jesús Fleta, L A Garciallop, M P Morellon, M BuenoAbstract:Objective: To develop equations, from some simple anthropometric measurements, for the prediction of body density from underwater weighing in male spanish children and adolescents. Subjects: One hundred and seventy-five males, aged 7.0–16.9 y, participated in this study, they were recruited from primary and secondary schools. Measurements: Body weight and height and Skinfold Thicknesses by anthropometry, body density by underwater weighing. Results: Correlations between body density and body mass index (BMI) were high until 14.0–16.9 y. Correlations between body density and log Σ 4 Skinfolds were higher than those with BMI at all ages. Log Σ 4 Skinfolds explained between 61% (14.0–16.9 y) and 68% (11.0–13.9 y) of the body density variance. Regression equations for body density from BMI and triceps Skinfold Thickness explained between 51% (14.0–16.9 y) and 68% (7.0–10.9 y) of the body density variance. Conclusions: The best estimators of body density in the children and adolescents studied were log Σ 4 Skinfolds and a combination of BMI and triceps Skinfold. Sponsorship: Universidad de Zaragoza

body fat measurement in elite sport climbers comparison of Skinfold Thickness equations with dual energy x ray absorptiometry
Journal of Sports Sciences, 2009Co-Authors: Vanesa Espana Romero, Luis A Moreno, Jonatan R Ruiz, Francisco B Ortega, Enrique G Artero, German Vicenterodriguez, Manuel J Castillo, Angel GutierrezAbstract:Abstract The aim of this study was to compare equations for estimating percentage body fat from Skinfold Thickness in elite sport climbers by assessing their agreement with percentage body fat measured using dual-energy X-ray absorptiometry (DXA). Skinfold Thickness was measured in a convenience sample of 19 elite sport climbers [9 women and 10 men; mean age 31.2 years (s = 5.0) and 28.6 years (s = 3.6), respectively]. Percentage body fat was estimated using 17 different equations, and it was also measured by DXA. A significant inter-methods difference was observed for all equations, except for Durnin's equation in men (inter-methods difference: −0.57% and −0.29%; 1.96 s: 5.56 and 5.23 for Siri's and Brozek's equation, respectively) and women (inter-methods difference: −0.67% and −1.29% for Siri's and Brozek's equation, respectively), and for Wilmore's equation using Siri's body fat equation in women (inter-methods difference: −1.86%). In women, the limits of agreement were lower when using Durnin's equat...

body fat in neonates and young infants validation of Skinfold Thickness versus dual energy x ray absorptiometry
The American Journal of Clinical Nutrition, 2002Co-Authors: H Schmelzle, C FuschAbstract:Background: There is an interest in noninvasive measurement of body fat in newborns and infants. Measurement of Skinfold Thickness (SFT) is a simple clinical method. Objective: We correlated fat mass (FM) values of neonates and infants predicted from SFT measurements and compared them with FM values measured by dual-energy X-ray absorptiometry (DXA), a validated in vivo method for determining body fat. Design: The weight, length, body composition (DXA measurement of FM and percentage of body fat), and SFT of 104 healthy term and preterm infants were measured at 0, 2, and 4 mo of age. Results: Mean (± SD) FM determined by DXA increased from 440 ± 220 g at birth to 1310 ± 450 g at 2 mo of age and to 2170 ± 605 g at 4 mo of age. The percentage of body fat increased from 13.3% at birth to 24.5% and 31.2% at 2 and 4 mo of age, respectively. An equation was developed to calculate FM (in g) in newborns by using the sum of SFT measurements (in mm) and body length (l; in cm): FM = 68.2 · � SFT 0.0162 · l � 172.8 (R 2 = 0.948, P 2000 g, respectively.

Design The weight, length, body composition (DXA measurement of FM and percentage of body fat), and SFT of 104 healthy term and preterm infants were measured at 0, 2, and 4 mo of age. Results Mean (+/- SD) FM determined by DXA increased from 440 +/- 220 g at birth to 1310 +/- 450 g at 2 mo of age and to 2170 +/- 605 g at 4 mo of age. The percentage of body fat increased from 13.3% at birth to 24.5% and 31.2% at 2 and 4 mo of age, respectively. An equation was developed to calculate FM (in g) in newborns by using the sum of SFT measurements (in mm) and body length (l; in cm): FM = 68.2 x SigmaSFT((0.0162) x l) - 172.8 (R(2) = 0.948, P Conclusions With the use of statistical bootstrap analysis, the results provide an in vivo validation of SFT measurements against DXA for newborns and young infants. Body fat measurements by SFT correlate with FM values determined by DXA (R(2) = 0.936). Estimation of nutritional status is possible with errors (SD) of +/- 75, +/- 170, +/- 300, and +/- 380 g for infants with an FM 2000 g, respectively.

mid upper arm circumference in pregnant women and birth weight in newborns as substitute for Skinfold Thickness findings from the maasthi cohort study india
BMC Pregnancy and Childbirth, 2021Co-Authors: Giridhara R Babu, Aritra Das, Eunice Lobo, R Deepa, Daisy A John, Prashanth Thankachan, Sonalini Khetrapal, Sara E Benjaminneelon, Gvs MurthyAbstract:Estimating total body fat in public hospitals using gold-standard measurements such as air displacement plethysmography (ADP), deuterium oxide dilution, or dual-energy X-ray absorptiometry (DXA) is unaffordable, and it is challenging to use Skinfold Thickness. We aimed to identify the appropriate substitute marker for Skinfold Thickness to estimate total body fat in pregnant women and infants. The study is part of a prospective cohort study titled MAASTHI in Bengaluru, from 2016 to 19. Anthropometric measurements such as body weight, head circumference, mid-upper arm circumference (MUAC), and Skinfold Thickness were measured in pregnant women between 14 and 36 weeks of gestational age; while measurements such as birth weight, head, chest, waist, hip, mid-upper arm circumference, and Skinfold Thickness were recorded for newborns. We calculated Kappa statistics to assess agreement between these anthropometric markers with Skinfold Thickness. We found the highest amount of agreement between total Skinfold Thickness and MUAC (Kappa statistic, 0.42; 95 % CI 0.38–0.46) in pregnant women. For newborns, the highest agreement with total Skinfold Thickness was with birth weight (0.57; 95 % CI 0.52–0.60). Our results indicate that MUAC higher than 29.2 cm can serve as a suitable alternative to total Skinfolds-based assessments for obesity screening in pregnancy in public facilities. Similarly, a birth weight cut-off of 3.45 kg can be considered for classifying obesity among newborns. Mid-upper arm circumference and birth weight can be used as markers of Skinfold Thickness, reflecting total body fat in pregnant women and the infant, respectively. These two anthropometric measurements could substitute for Skinfold Thickness in low- and middle-income urban India settings.
