title: The indentification and evaluation of measurement variability in the anthropometry of preschool children.
abstract: Measurement variability estimates for 18 different anthropometric dimensions were collected within the context of an ongoing longitudinal in vestigation of preschool Guatemalan children. Estimates of total measurement variance, intra-observer variance, and short-term intra-subject variance are presented for each variable. A simple procedure for the evaluation of measurement variance in cross-sectional and longitudinal investigations is described in which the total measurement variance is expressed as a percentage of the appropriate inter-subject variance. This statistic serves as an index of the relative reproducibility of anthropometric variables.
