Projects

• Fifth National Growth Study: this study recorded the height and weight of more than 20,000 children in the Netherlands. The data have been used to produce growth charts and to calculate, for example, the height and weight of children and young people in the Netherlands.
• Weight loss in breastfed babies: TNO has calculated a reference range of values for average, normal, weight loss in neonates in the first ten days of life.
• D-score and D-screening: the D-score (Developmental Score) is a new measure for using the Van Wiechen Scheme. It measures the development of children between 0 and 2 years, and compares it to that of their peers. D-screening has been developed to identify young children at risk of a general developmental deficit. The instrument is based on the D-score and on the background characteristics of parent and child.
