Validity and reliability of self-reported stature and weight of U. S. adolescents

Article Abstract:

This article examines the accuracy of self-reported values of height and weight among American adolescents participating in a national health survey. Findings indicate that many adolescents were unable or refused to report their weight and that self-report bias and errors were most prevalent in participants under fourteen years old.

Reliability and validity of parental measurements of infant size

Article Abstract:

This article evaluates the accuracy of infant size measurements taken by parents using simple tools and illustrated instructions. Findings indicate that parental measurements of the infant's body length and head, arm, and abdominal circumferences demonstrated high reliability and were strongly correlated with measurements obtained by a trained observer.

Maturation-related deviations and misclassification of stature and weight in adolescence

Article Abstract:

Adolescent increase in maturation-related misclassification comes mostly from changes in size-for-maturation relationships not from changes in variation in maturational status as such. Maturation-related deviations have been studied in 999 adolescents as has misclassification of weight/stature, for which normal deviations have been quantified as they relate to variation in maturational status. Using reference data based on chronological age brings misclassification.
