Objective To assess the period during infancy and childhood in which growth is most associated with adolescent adiposity and the metabolic syndrome (MS) and whether this differs depending on maternal smoking during pregnancy. Study design A longitudinal population-based cohort study among 772 girls and 708 boys. Results Weight gains between ages...

We propose a new multiple imputation technique for imputing squares. Current methods yield either unbiased regression estimates or preserve data relations. No method, however, seems to deliver both, which limits researchers in the implementation of regression analysis in the presence of missing data. Besides, current methods only work under a...

Background. The Steep Ramp Test (SRT), a feasible, reliable, and valid exercise test on a cycle ergometer, may be more appealing for use in children in daily clinical practice than the traditional cardiopulmonary exercise test because of its short duration, its resemblance to children's daily activity patterns, and the fact that it does not...

In multiple imputation (MI), the resulting estimates are consistent if the imputation model is correct. To specify the imputation model, it is recommended to combine two sets of variables: those that are related to the incomplete variable and those that are related to the missingness mechanism. Several possibilities exist, but it is not clear...

OBJECTIVES: Asians have a smaller muscle mass and a larger fat mass at the same body mass index (BMI) than most other ethnic groups. Due to a resulting higher cardiometabolic risk, the BMI cut-offs for overweight and obesity were lowered for adults. For Asian children universal criteria apply. The objectives of this study were to determine the...

Background South Asian babies born in developed countries are generally lighter than babies from other ethnic groups born in the same country. While the mean birth weight of Caucasian babies in the Netherlands has increased the past decades, it is unknown if the mean birth weight of South Asian babies born in the Netherlands has increased or if...

Design/methodology/approach - After pilot-testing, the 47-item IWPQ was field-tested amongst a representative sample of 1,181 Dutch blue, pink, and white collar workers. Factor analysis was used to examine whether the four-dimensional conceptual framework could be confirmed. Rasch analysis was used to examine the functioning of the items in more...

An important goal of growth monitoring is to identify genetic disorders, diseases or other conditions that manifest themselves through an abnormal growth. The two main conditions that can be detected by height monitoring are Turner’s syndrome and growth hormone deficiency. Conditions or risk factors that can be detected by monitoring weight or...

Aim: To assess and compare the secular trend in age at menarche in Dutch girls (1955-2009) and girls from Turkish and Moroccan descent living in the Netherlands (1997-2009). Methods: Data on growth and maturation were collected in 20,867 children of Dutch, Turkish and Moroccan descent in 2009 by trained health care professionals. Girls, 9 years...

Background: Records show that mean height in The Netherlands has increased since 1858. 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.Methods:We compared the height of young Dutch people aged 0...

In het Terneuzen Onderzoek naar Preventie zijn overgewicht en cardiometabole risicofactoren op jongvolwassen leeftijd bestudeerd in relatie tot de veranderingen in body mass index (BMI) tussen de geboorte en 18-jarige leeftijd. Deze studie is gebaseerd op het Terneuzen Geboorte Cohort, waarbij prospectief verkregen gegevens zijn verkregen via de...

Background: Many questionnaires for measuring physical activity (PA) exist. This complicates the comparison of outcomes. Methods: In 8 European countries, PA was measured in random samples of 600 persons, using the IPAQ as a 'bridge' to historical sets of country-specific questions. We assume that a unidimensional scale of PA ability exists on...

Objective: To assess the prevalence of cardiovascular risk factors in severely obese children and adolescents. Methods: A nationwide prospective surveillance study was carried out from July 2005 to July 2007 where paediatricians were asked to report all new cases of severe obesity in 2-18-year-old children to the Dutch Paediatric Surveillance...

Objectives: To assess the distribution of height, weight, and head circumference (HC) in preterm infants for ages 0-4 years, by gestational age (GA) and sex, and to construct growth reference charts for preterm-born children, again by GA and sex, for monitoring growth in clinical practice. Study design: The community-based cohort study covered a...

Background: Clark and Watson developed the tripartite model in which a symptom dimension of 'negative affect' covers common psychological distress that is typically seen in anxious and depressed patients. The 'positive affect' and 'somatic arousal' dimensions cover more specific symptoms. Although the model has met much support, it does not...

We hebben het er liever niet over, maar allemaal worden we geplaagd door ontbrekende gegevens. Het liefst moffelen we problemen veroorzaakt door ontbrekende gegevens onder het tapijt. De standaard ‘oplossing’ voor missing data bestaat uit het weglaten van de onvolledige rijen uit de analyse. In veel software gebeurt dit automatisch, en als...
