..We hypothesize that children with asthmatic symptoms are less physically active, which may contribute to the development of overweight...

..The LR is firmly rooted within both statistical and decision theory and can be used to estimate the absolute probability of disease...

..stefvanbuuren.nl/puberty. The stage line diagram expresses status and tempo of discrete changes on a continuous scale. Wider application of these measures scores opens up new analytic possibilities...

..The JM approach introduced biases in the reference curves, whereas FCS did not. The paper concludes that FCS is a useful and easily applied flexible alternative to JM when no convenient and realistic joint distribution can be specified...

..The method is an affordable and efficient strategy to estimate regional growth distributions where the standard costly alternatives are not an option...

..This would suggest that in countries without a newborn screening program for CF, FTT could be used as a clinical screening tool. The aim of this study is to assess the diagnostic performance of FTT for identifying children with CF...

..However, the effectiveness of slowed growth as a tool for identifying children with CD is unknown. Our aim is to study the diagnostic efficiency of several growth criteria used to detect CD children...

..In the present paper we evaluate the diagnostic work-up in secondary health care according to existing consensus guidelines and study the frequency of underlying medical disorders...

..This resulted in guidelines for referral. In this study we evaluate the referral pattern of short stature in primary health care using these guidelines, comparing it with cut-off values mentioned by the WHO...

..Studies on the association between head circumference (HC) and height or weight have shown variable results...

..35, P <0.01). CONCLUSION: Waist circumferences can be used to screen for increased abdominal fat mass in children, whereby a cut-off point of 1.3 standard deviation score seems most suitable...

..If similar dropout mechanisms operate in the Multicentre Growth Reference Study, then the WHO weight-for-age standards are expected to be systematically different from those for the entire group of 1,743 infants...

..Prevalences of overweight in The Netherlands, defined by international cut-off points, are presented in 14 500 children of Dutch origin, 2904 of Turkish and 2855 of Moroccan origin, aged 0-21 y...

..This study looks at whether this trend in the world's tallest nation is continuing. We consider the influence of the geographical region, and of the child and parental education, on changes in height...

..To assess the prevalence of overweight and obesity in children living in the Netherlands and compare the findings with the Third and Fourth National Growth Studies carried out in 1980 and 1997, respectively...

..The aim of this study was to gain insight into contraception practised and related to breastfeeding duration...

..CONCLUSION: Turkish children are considerably shorter and more overweight than Dutch children. Separate growth charts for Turkish children in The Netherlands are useful for growth monitoring...

..To assess the prevalence of overweight and obesity among Dutch children and adolescents, to examine the 30-years trend, and to create new body mass index reference charts...

..The validity of the rule of thumb that infants may have a weight loss of 10% in the first days after birth is unknown. We assessed the validity of this and other rules to detect breast-fed infants with hypernatraemic dehydration...

..Difference scores between sessions can be used to evaluate developmental velocity on the individual level. To our knowledge this is the first developmental scale for children with such properties...

..To develop and evaluate two artificial neural network (ANN) models based on single-sensor accelerometer data and an ANN model based on the data of two accelerometers for the identification of types of physical activity in adults...

..To determine the size of the growth deficit in Dutch monozygotic and dizygotic twins aged 0-2.5 years as compared to singletons and to construct reference growth charts for twins...

..Many questionnaires for measuring physical activity (PA) exist. This complicates the comparison of outcomes...

..Optimal guidelines should have high yield and low complexity. The goal is to fit procedures for screening and subsequent treatment of hypertension optimally to a specific population...

..Similar results hold for covariate-drug interactions. We illustrate our results using two examples...

..Multiple imputation (MI) accounts for imputation uncertainty that allows for adequate statistical testing. We developed and tested a methodology combining MI with bootstrapping techniques for studying prognostic variable selection...

..7% (95% CI 11.5-15.9%) of the children referred to a general paediatric outpatient clinic were or had been on a diet. However, it is unknown how many children in a random population are or have been on a diet...
