  1. Sex differences in weight in infancy and the British 1990 national growth standards.

    Article - En anglais

    Objectives-To determine if there is a sex difference in infancy in the new British national standards for weight (based on data from 1990).

    Design-Weight data in a birth cohort were compared with the 1990 standards and Tanner and Whitehouse (1966) standards up to age 12 months.

    Setting-Newcastle upon Tyne

    Subjects-3418 term infants.


    Our cohort showed a mean difference in standard deviation scores of 0.42 between boys and girls (P<0.0001) when compared with the 1990 standards.

    Two and a half times as many girls as boys had weights below the 3rd centile during the first year, with an equivalent excess of boys above the 97th centile (P<0.0001).

    Similar results were found with Tanner and Whitehouse standards.

    Conclusions-These differences could result in substantial sex bias in the identification of poor growth in early childhood.

    The standards need modification.
