Fredriks, A.M. (author), van Buuren, S. (author), Fekkes, M. (author), Verloove-Vanhorick, S.P. (author), Wit, J.M. (author)The aim of this study was to present age references for waist circumference (WC), hip circumference (HC), and waist/hip ratio (WHR) in Dutch children. Cross-sectional data were obtained from 14,500 children of Dutch origin in the age range 0-21 years. National references were constructed with the LMS method. This method summarises the...article 2005

(author)Objective: In newborn screening programs for congenital adrenal hyperplasia, 17-α-hydroxyprogesterone (17OHP) cutoff levels are based on birth weight (BW) or on gestational age (GA). We investigated which approach would result in the greatest specificity and sensitivity. Study design: For the determination of 17OHP, a neonatal 17OHP assay was...article 2005

(author), TNO Preventie en Gezondheid (author)The number of referrals under strict adherence to the Dutch consensus guidelines for short stature was estimated using longitudinal data from 970 children (0-10 years). Results showed that over 38% of all children would have to be referred one or more times. There is therefore a clear need to revise the current guidelines.article 2004
