Anthropometric estimation of neonatal body composition

摘要: Abstract OBJECTIVE: Estimation of neonatal body composition can be useful in the understanding fetal growth. However, methods such as total water and electric conductivity are expensive not readily available. Our primary purpose was to develop an anthropometric model estimate prospectively validate against secondarily tocompare our a previously published formula with conductivity. STUDY DESIGN: A 194 neonates had estimates according (group 1). Parental morphometrics, gestational age, race, sex, parity, measurements including birth weight, length, head circumference, skinfolds (triceps, subscapular, flank, thigh) were correlated fat by use stepwise regression analysis. The validated second group 65 2). RESULTS: There no significant differences any parental or between groups 1 2. In 1, 78% variance explained flank skifold ( R 2 = 0.78, p 0.0001). When subjects 2, stronger correlation 0.84, 0.0001) estimated compared other 0.54, 0.11) difference CONCLUSIONS: developed used reasonably predict mass at birth.
