In celebration of Global Health Trials' fifth birthday (May 11th 2015) Professor Trudie Lang, Principal Investigator of the programme, talks to us about why Global Health Trials was started, why people should share their experience, and what the future holds.
Preterm birth has been difficult to study and prevent because of its complex syndromic nature. The INTERGROWTH-21st Project presents a new approach to this problem. This paper explains the results of the first application of a prototype classification system for preterm birth based on twelve phenotypes, using data from the Newborn Cross-Sectional Study of the INTERGROWTH-21st Project. http://archpedi.jamanetwork.com/article.aspx?articleid=2050591
The INTERGROWTH-21st Project Neurodevelopment Package: A Novel Method for the Multi-Dimensional Assessment of Neurodevelopment in Pre-School Age Childrenby INTERGROWTH-21st
The INTERGROWTH-21st Neurodevelopment Package is a multi-dimensional instrument measuring early childhood development (ECD). Its developmental approach may be useful to those involved in large-scale ECD research and surveillance efforts. This paper describes neurodevelopment tools for preschoolers and the systematic approach leading to the development of the Package. The Package measures vision; cortical auditory processing; and cognition, language skills, behavior, motor skills, and attention in 35-45 minutes. Sleep-wake patterns are also assessed. Tablet-based applications with integrated quality checks and automated, wireless electroencephalography make the Package easy to administer in the field by non-specialist staff. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0113360
International standards for early fetal size and pregnancy dating based on ultrasound measurement of crown-rump length in the first trimesterby INTERGROWTH-21st
The INTERGROWTH-21st Project has produced the first, international standards for relating fetal crown-rump length to gestational age.
International standards for newborn weight, length, and head circumference by gestational age and sex: the Newborn Cross-Sectional Study of the INTERGROWTH-21st Projectby INTERGROWTH-21st
These international anthropometric standards were developed to assess newborn size in routine clinical practice that are intended to complement the WHO Child Growth Standards and allow comparisons across multiethnic populations.
International standards for fetal growth based on serial ultrasound measurements: the Fetal Growth Longitudinal Study of the INTERGROWTH-21st Projectby INTERGROWTH-21st
Using the same methods and conceptual approach as the WHO child growth standards, the Fetal Growth Longitudinal Study of the INTERGROWTH-21st Project developed international growth and size standards for fetuses for clinical interpretation of routinely taken ultrasound measurements and for comparisons across populations.
The likeness of fetal growth and newborn size across non-isolated populations in the INTERGROWTH-21st Project: the Fetal Growth Longitudinal Study and Newborn Cross-Sectional Studyby INTERGROWTH-21st
Large differences exist in size at birth and in rates of impaired fetal growth worldwide. The relative effects of nutrition, disease, the environment, and genetics on these differences are often debated. In clinical practice, various references are often used to assess fetal growth and newborn size across populations and ethnic origins, whereas international standards for assessing growth in infants and children have been established. In the INTERGROWTH-21st Project, our aim was to assess fetal growth and newborn size in eight geographically defined urban populations in which the health needs of mothers were met and adequate antenatal care was provided. Through the Fetal Growth Longitudinal Study and Newborn Cross-Sectional Study, data showed that fetal growth and newborn length are similar across diverse georgraphical settings when mothers' nutritional and health needs are met, and environmental constraints on growth are low. The findings for birthlength are in strong agreement with the WHO Multicentre Growth Reference Study (MGRS). These results provide the conceptual frame to create international standards for growth from conception to newborn baby, which will extend the present infant to childhood WHO MGRS standards.
