Background: There is limited information on the ability of demographic or lifestyle factors to predict short term changes in weight status during childhood.Objective and hypotheses: To study the effect of parental (educational level, BMI status and perception of child’s weight status) and childhood factors (eating habits, sedentary behaviour and physical activity), on 1-year BMI increments by the use of BMI, BMI SDS and BMI SDS conditional gain....

Introduction: Physical growth according to genetic potential is a hallmark of childhood health [1]. Childhood growth is complex and the physiological processes involved in promoting healthy growth are not fully understood, including the gut microbiota. The gut microbiota matures from birth towards adulthood, and this process might be affected by several factors, including mode of delivery, food intake and antibiotic treatment. The bacterial gut microbiota is observed to be mor...

Objectives: Current safety data do not indicate an association of GH therapy with increased risk for development/progression of tumours, or worsening of congenital cardiac conditions in individuals with Noonan syndrome (NS); however, data are limited. This report describes real-world safety data on GH therapy in paediatric patients with NS.Methods: Two complementary non-interventional, multicentre studies, NordiNet IOS (NCT00960128) and ANSWER Program (N...

Aim: A decline in the age at menarche has been reported in recent years in several well-off populations. The prevalence of childhood overweight and obesity has increased during the last decades with some levelling off during the last years. The aim of the present study was to study the association between parameters of overweight and menarche in Norway.Material: Cross-sectional data from The Bergen Growth Study, collected in 2003–2006 from 4016 girl...

Background: Anthropometry is the general tool for defining overweight and obesity, with BMI cut-offs adjusted for sex and age, as the most commonly used variable in childhood.Objective and hypotheses: Based on the interrelationships between BMI and different overweight-related anthropometric variables we wanted to find out which anthropometric variables contribute most to the variation in BMI, and how age affect this picture?Method...

Background: Metformin is increasingly used in pregnancy and passes the placenta. Data on long-term effect on the offspring is essentially lacking. We explored possible effects of intrauterine metformin exposure on metabolic health, in 8-years-old children of women with PCOS.Methods: Follow-up of children from the PregMet-study - an RCT comparing metformin (2000 mg) to placebo during PCOS pregnancies. The primary endpoint was Body Mass Index (BMI). Second...

Background: Prader orchidometry has been the standard method for evaluating testicular size. As this technique is subjective and tends to overestimate the testicular volume, ultrasound has been proposed as a more reliable method.Objective: To evaluate the intra- and inter-observer agreement of ultrasound measurements of testicular volume and comparison with Prader orchidometry.Materials and methods: Length, width and depth of the r...

Background: Recent research has demonstrated earlier testicular and pubertal development in Western boys. New ultrasound-based references of testicular growth in Norwegian boys are now available. Population specific references for FSH, LH and sex steroid hormones have not been previously available in Norwegian children and adolescents.Objective and hypotheses: We aimed to provide an elaborate description of pubertal development in a sample of contemporar...

Background and aim: Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals found in everyday consumer products. These chemicals are considered endocrine disruptive. However, their effect on pubertal onset and development is still unclear. The aim of the current study was therefore to explore the relationship between PFAS exposure and pubertal development using novel objective pubertal phenotyping, e.g., ultrasound-determined testicular v...
