Area of Science:

  • Obstetrics and Gynecology
  • Pediatrics
  • Global Health

Background:

  • Accurate birthweight for gestational age standards are crucial for assessing infant health.
  • Existing standards may not accurately reflect diverse populations, necessitating localized data.
  • Low birthweight is a significant indicator of neonatal risk.

Purpose of the Study:

  • To derive and describe birthweight for gestational age standards for infants born in Harare, Zimbabwe.
  • To compare these standards with existing definitions of low birthweight.
  • To investigate sex and parity differences in birthweight at various gestational ages.

Main Methods:

  • Analysis of data from 5,872 women with reliable menstrual dates in Harare.
  • Calculation of smoothed 5th, 50th, and 95th centiles for birthweight across gestational ages (24-42 weeks).

  • Fitting linear quadratic functions to the centile data.

    • Main Results:

    • Established smoothed birthweight percentiles for gestational ages 24-42 weeks.
    • Identified male infants as significantly heavier than females from 36 weeks gestation.
    • Observed parity differences in birthweight emerging at 38 weeks gestation.

    Conclusions:

    • The derived standards provide a localized reference for infant growth in Harare.
    • The findings support redefining low birthweight in this population to ≤2,000 grams.
    • This adjustment aims to improve the identification of at-risk neonates.
