Strengthening capacity to apply health research evidence in policy making: experience from four countries

by Sarah Hawkes, Bhupinder K Aulakh, Nidhee Jadeja, Michelle Jimenez, Kent Buse, Iqbal Anwar, Sandhya Barge, M. Oladoyin Odubanjo, Abhay Shukla, Abdul Ghaffar, Jimmy Whitworth

Little experience of strengthening the capacity of policy makers in low- and middle- income countries has been published to date. This article describe the experiences of five projects (in Bangladesh, Gambia, India and Nigeria) - author available to comment!

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

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.

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.
