Characterizing Fetal Growth and Relations Between Maternal Covariates, Fetal Growth, and Birth Outcomes

A major focus area of HBGD is preterm birth including prevention and treatment. To intervene, we need to know gestational age. We do not have many good resources for estimating gestational age in many settings. Birth weight often is used as a surrogate, but this measure can vary between populations around the world. Therefore, we need to better understand how growth trajectories differ between populations. The goals for this series of rallies are to evaluate the collection of HBGDki data sets, learn more about how fetal growth trajectories differ between populations, learn how these different trajectories link to gestational age, and learn about the tools that can estimate gestational age more accurately. If there are differences between populations, how much of the differences may be attributed to modifiable or non-modifiable factors?

Focus

Determine fetal growth patterns and population differences using several data sets and determine if one growth standard can be applied to all geographies.

Background

Intervention with pre-term birth requires knowing gestational age. There are not many good resources for estimating gestational age in many settings. Birth weight often is used as a surrogate, but this measure can vary between populations.

value

This work provides insight into the geographic differences in fetal growth and potential impact of maternal characteristics on fetal growth.
