Area of Science:

  • Pediatric growth monitoring
  • Neonatal and infant health assessment
  • Biometric reference data development

Background:

  • Accurate growth assessment is vital for preterm low-birth-weight infants.
  • Existing reference data may not adequately cover the specific needs of this population.
  • Age-independent reference data is needed for comprehensive evaluation.

Purpose of the Study:

  • To establish age-independent reference data for head circumference-for-length in preterm low-birth-weight infants.
  • To cover head circumference ranges from 34-49 cm and length from 52.0-102.9 cm.
  • To provide data applicable from birth up to 36 months of gestation-adjusted age.

Main Methods:

  • Utilized data from 867 preterm infants across diverse ethnic groups.

  • Collected serial measurements at 9 ages from birth to 36 months gestation-adjusted age.
  • Employed a serial data modeling approach to estimate head circumference and length.

    • Main Results:

    • Generated tables and charts detailing means, standard deviations, and percentiles for each sex.
    • Data is stratified by birth weight categories: very low (< or = 1500 g) and low-birth-weight (1501-2500 g).
    • Reference data is presented in 3-cm intervals of infant length.

    Conclusions:

    • The developed tables and charts serve as a valuable clinical tool.
    • Aids clinicians in evaluating and monitoring head circumference in preterm low-birth-weight infants.
    • Facilitates growth assessment by considering body length alongside head circumference.
