  1. Fulltext. Effects of Cryptosporidium parvum infection in Peruvian children : Growth faltering and subsequent catch-up growth.

    Article - En anglais


    The authors conducted a 2-year (1989-1991) community-based longitudinal study in a shantytown in Lima, Peru, to examine the effect of Cryptosporidium parvum infection on child growth during the year following the onset of infection.

    A cohort of children, aged 0-3 months at recruitment, was followed monthly for anthropometrics, weekly for stool samples, and daily for diarrheal status.

    Data from 185 children in the cohort permitted a comparison of growth in C. parvum-infected and noninfected children.

    The analyses fitted smooth, flexible curves with a linear random-effects model to estimate growth differences between C. parvum-infected and noninfected children.

    Children infected with C. parvum experienced growth faltering, both in weight and in height, for several months after the onset of infection, followed by a period of catch-up growth.

    Younger children took longer to catch up in weight than did older children.

    Catch-up growth, however, did not occur in children infected between ages 0 and 5 months.

    These children did not catch up in height, and one year after infection they exhibited an average deficit of 0.95 cm (95% confidence interval (Cl) 0.38-1.53) relative to noninfected children of similar age.

    Stunted children who became infected also did not catch up in either weight or height, and one year after infection they exhibited a height deficit of 1.05 cm (95% Cl 0.46-1.66) relative to noninfected, stunted children of similar age. (...)
