    Left ventricular hypertrophy has been established as an independent risk factor for the development of cardiovascular morbidity and mortality. It is clear that left ventricular mass increases during childhood and adolescence with body growth. The extent to which other factors, such as obesity, stage of sexual maturation, and level of blood pressure, determine left ventricular mass has been controversial. Methods and Results. The study was a cross-sectional evaluation of the relationship of left ventricular mass determined by echocardiography with lean body mass and fat mass determined by dual-energy x-ray absorptiometria, which is the most valid and reliable method for determination of body composition in children and adolescents.

    Bioelectric impedance analysis (BIA) has been widely used for assessment of body composition in healthy subjects but has not been validated in malnourished patients. This study compared calculation of fat-free mass (FFM) by five methods to determine whether the currently used equations for total body water (TBW) as assessed by BIA were applicable to 19 malnourished patients with Crohn's disease. When compared with TBW assessed by H2(18)O dilution, BIA was higher by 5.9 +/- 1.1% (P < 0.005). A stepwise-multiple-regression equation was derived to validate BIA: TBW (kg) = 0.25 (ht2/resistance) + 0.29 (wt) + 3.63 (r = 0.97, SEE = 0.28). Comparison of the hydration of FFM (TBW by 18O dilution/FFM) between methods showed that total body potassium (TBK) gave a significantly higher value when compared with the reference method of body protein, mineral, and 18O analysis. Dual-energy x-ray absorptiometry (DXA) provided a value for TBW/FFM in close agreement with the reference method. We conclude that BIA overestimates TBW, and TBK underestimates FFM in malnourished patients. DXA provides an accurate measurement of body fat in malnutrition.

    The objectives of this study were 1) to examine interrelations among intraabdominal adipose tissue (IAAT) and other adiposity indexes, 2) to identify a visceral obesity index that is independent of total adiposity, and 3) to examine sex and ethnic (white compared with African American) differences in IAAT. We measured IAAT and subcutaneous abdominal adipose tissue (SAAT) using computed tomography, and total fat mass (FM) by dual-energy X-ray absorptiometry in a heterogenous sample of 101 children aged 7.7 +/- 1.6 y weighing 33.2 +/- 12.6 kg. IAAT was highly variable (mean +/- SE; 31 +/- 22 cm2; range: 7-107 cm2) and related to SAAT (r = 0.87) and FM (r = 0.81)...Continua.

    Body mass index (BMI) has been recommended for use in adolescent screening programs to select subjects with excess body fat for appropriate interventions. No systematic evaluation of MBI in screening for high degrees of adiposity was available when these recommendations were formulated. The purpose of this paper was to evaluated the screening performance of BMI using appropriate epidemiologic methods. Percentage body fat (TBF%) was measured by dual-energy X-ray absorptiometry DXA) in a convenience sample of 230 (119 males, 111 females) health Australian volunteers aged 4-20 y inclusive. Receiver operating characteristic (ROC) curves were prepared for detecting TBF% at or beyond the 85th percentile, using BMI as the screening test....Continua.

    The body mass index (BMI), defined as weight/height, is often used to monitor childhood obesity. BMI values for 979 children (438 White, 283 Black, and 258 Hispanic) aged 3-18 years living in the Houston, Texas, metropolitan area from 1994 to 1998 were compared with percentage of fat (%Fat) measurements obtained by using dual-energy x-ray absorptiometry. The associations between %Fat and BMI were statistically significant (r2 = 0.34-0.70, p < 0.0005) and were gender and ethnic dependent (p < 0.0005), indicating that BMI can provide a general description of the adiposity characteristics of a healthy pediatric population. However, BMI was a poor predictor for the individual child, with a standard error for %Fat of 4.7-7.3% of body weight. It is advantageous to identify accurately, as early as possible, those children who truly have excess adiposity, but this assessment should not be done at the risk of falsely mislabeling a significant number of healthy children as overweight or obese.

    The aim of our study was to assess the effects of long-term treatment with inhaled budesonide (BUD) on total body bone mineral density (BMD), total body bone mineral capacity (BMC), total bone calcium (TBC), and body composition in children with asthma. Dual energy X-ray absorptiometry (DEXA scan) was performed in 157 asthmatic children treated with inhaled BUD at a mean daily dose of 504 microg (range, 189 to 1,322 microg) for 3 to 6 yr (mean, 4.5 yr). Measurements were compared with those of 111 age-matched children also suffering from asthma but who had never been treated with exogenous corticosteroids for more than 14 d (control group). There were no statistically significant differences between the two groups in BMD (BUD = 0.915 g/cm2, controls = 0.917 g/cm2), BMC (BUD = 1,378 g, controls = 1,367 g), TBC (BUD = 524 g, controls = 519 g), or body composition (lean body weight = 27,600 g [BUD] and 26,923 g [control], % body fat = 20.1% [BUD] and 20.3% [control]). Furthermore, there was no correlation between any of these parameters and duration of treatment, accumulated or current dose of budesonide. Three to six years of treatment with inhaled budesonide at an average daily dose of 504 microg has no adverse effect on total BMD, total BMC, TBC, or body composition in children with chronic asthma.

    Multicompartment models are of growing importance in the study of body composition in humans. This study compares two improved four-compartment (water, protein, mineral, and fat) models that differ in expense, technological complexity, and radiation exposure. Primary data (from 31 subjects) for the first model were derived by dual-photon absorptiometry, 3H2O dilution, and hydrodensitometry and for the second model by delayed and prompt gamma neutron-activation analysis and 3H2O dilution. Estimates of fat, protein, and mineral from the first model were highly correlated with those from the second model (r = 0.98, 0.72, and 0.94, respectively; all p less than 0.001). The proportions of body weight represented by water, protein, mineral, and fat for the simpler first model (0.532, 0.155, 0.048, and 0.265) were similar to compartment fractions provided by the more complex and costly second model (0.532, 0.143, 0.046, and 0.279). Multicompartment body composition models can thus be developed from increasingly available techniques that compare favorably with similar results derived from limited-access instrumentation.

    En 198 escolares, 108 hombres y 90 mujeres, cuyas edades fluctuaban entre los 6 y los 13 años de edad, se determinó la densidad y el contenido mineral óseo en cuerpo entero, columna lumbar y cadera de lado no dominante, mediante densitometría isotópica de doble haz, (Gd 153). Se encontró que la masa ósea total (MOT) y la densidad mineral ósea (DMO) de as tres zonas analizadas aumentan con la edad. A los 12 años las mujeres tuvieron valores significativamente mayores de MOT y DMO en cuerpo entero. En columna las mujeres tuvieron una densidad significativamente mayor que los valores entre los 11 y los 13 años. Al comparar la DMO de columna y de cuello femoral de las escolares de 9 años de edad de este estudio, con la de mujeres adultas jóvenes chilenas (masa ósea máxima), se observó que aún les faltaba adquirir un 36% de la mineralización en columna y un 18% en la cadera. Se enfatiza sobre la importancia de contar con valores normales de mineralización ósea par aun adecuado diagnóstico y tratamiento de los niños con problemas de mineralización y para la evaluación de programas específicos destinados a corregir estas deficiencias.

    Dual-energy x-ray bone densitometry was used to study the lumbar vertebral bone mass in 218 healthy children (134 girls and 84 boys) aged 1-19 years. Vertebral bone mass increased with weight, age, and pubertal Tanner stage. Results of multiple regression analyses showed that Tanner stage and weight were the best predictive indicators of bone mass and bone mineral density. The influences of age, sex, race, physical activity, and diet were not significant when Tanner stage and weight were controlled. Two tables of predictive intervals for lumbar vertebral bone mineral density in healthy children (one based on Tanner stage and weight; the other, on age and weight) are presented. With normative data now available for use with this precise technique, clinicians can better detect abnormal bone mineral density in children and evaluate changes in mineralization over time.

    Detailed associations between physical activity (PA) subcomponents, sedentary time, and body composition in preschoolers remain unclear. OBJECTIVE: We examined the magnitude of associations between objectively measured PA subcomponents and sedentary time with body composition in 4-y-old children. DESIGN: We conducted a cross-sectional study in 398 preschool children recruited from the Southampton Women's Survey. PA was measured by using accelerometry, and body composition was measured by using dual-energy X-ray absorptiometry. Associations between light physical activity, moderate physical activity (MPA), vigorous physical activity (VPA), and moderate-to-vigorous physical activity (MVPA) intensity; sedentary time; and body composition were analyzed by using repeated-measures linear regression with adjustment for age, sex, birth weight, maternal education, maternal BMI, smoking during pregnancy, and sleep duration.
