Size at Birth by Gestational Age

We created curves from a cross-sectional study conducted on consecutive Malaysian neonates born in a maternity hospital in Kuala Lumpur (1). Anthropometric measurements were made within the first 36 hours of life. A total of 12,527 births were recorded, and 4,046 were were excluded due to parents not being available for interviewing, the child not being Malaysian, and/or gestational age being less than 28 weeks. This left 8,478 neonates who were analyzed for the study.

We constructed curves from 35-42 weeks of gestation. We excluded gestational ages 28-34 weeks due to very small sample sizes in those groups. The curves here use the 10th-90th percentiles for both male and female infants.
