Public Release: 

New WHO international fetal growth charts

PLOS

A research article published in PLOS Medicine contributes to the evidence base regarding the use of population charts for detection of fetal growth disorders and how best to determine risk of complications.

In the article, Torvid Kiserud from the University of Bergen, Norway, and colleagues establish the World Health Organization fetal growth charts for head and abdominal circumference, length of the thigh bone, and fetal weight using ultrasound measurements during pregnancy. The researchers included 1,387 healthy women with low-risk pregnancies and unconstrained nutritional and social background from ten countries in Africa, Asia, Europe, and South America, and found that fetal growth showed considerable natural variation, differing significantly between countries, and that fetal growth was to a small extent influenced by maternal age, height, weight, and parity, and by fetal sex. These findings suggest that WHO charts for growth in estimated fetal weight are more suitable for international use than those commonly applied today, but may need to be adjusted for local clinical use to increase their diagnostic and predictive performance.

Competing Interests:

I have read the journal's policy and the authors of this manuscript have the following competing interests: GP is a WHO statistical consultant and has a contract to give statistical support to the Fetal Growth Study. GP has worked with WHO for 15 years and has a relationship with WHO, both paid (contracts) and unpaid. GP is also a good friend of many of the investigators involved in this study. LDP is a Board Member of the Perinatal Quality Foundation, a nonprofit organization related to the Society for Maternal Fetal Medicine. LDP has received research support from General Electric Medical Systems unrelated to fetal growth. LDP also lectures 1 or 2 times per year at an educational meeting supported by General Electric Medical Systems unrelated to fetal growth.
