AI Article Synopsis

  • The study aimed to create reference charts for measuring fetal growth in Karachi, Pakistan, involving 1228 women with singleton pregnancies.
  • Key fetal measurements like biparietal diameter, head circumference, abdominal circumference, and femur length were taken repeatedly until delivery and analyzed using regression techniques.
  • The resulting percentiles for these measurements are the first ever in Karachi, aiding in the diagnosis of fetal growth issues and laying groundwork for national growth charts.

Article Abstract

Objective: The aim of this study was to construct reference charts for fetal biometry in Karachi, Pakistan.

Methods: This was a prospective longitudinal study involving 1228 women with singleton pregnancies. Biparietal diameter, head circumference, abdominal circumference and femur length were measured repeatedly until delivery. Regression analysis and multilevel modeling was used to construct charts.

Results: The mean age of the women in this study was 28.0 years with standard deviation of 4.6. For each gestational age percentiles were calculated and charts were then constructed.

Conclusion: Our reference percentiles for fetal biometry measurements are the first of their kind in Karachi, Pakistan. They will not only help us in the diagnosis and management of fetal growth restriction but will provide the basis to develop charts at the national level.
