Background: That mortality is not increased in rhGH-treated patients when adjusting for birth characteristics was recently published (1). When applying a developed mortality model of the general population, the observed and expected deaths in rhGH-treated IGHD, ISS and SGA patients (n=3847) where 21 and 21.99, respectively. The model includes gender, age, calendar year, gestational age (GA), birth lengthSDS (BLSDS), birth weightSDS (BW...

Background: Very low birth weight (VLBW) infants tend to have slower postnatal growth than the fetuses of the same gestational age (GA)1. Higher nutrient intake and better early growth are associated with better neurocognitive outcomes; excessive nutrient intakes may lead to metabolic consequences. Nutrient intakes for optimal growth, body composition and neurodevelopment are not known.Objectives: To assess gr...

Background: Lifestyle interventions show a long lasting weight reduction in only 10–20% of obese children and adolescents. Leptin as one major player within the central regulation of food intake and energy expenditure is most likely to mediate the endogenous drive for weight regain.Objective and hypotheses: To estimate weight regain after weight loss and the role of leptin in regain.Method: We included 153 obese children/adole...

Background: In addition to its function in circadian rhythm Melatonin plays an important role in energy metabolism and body weight regulation. In animals pinealectomy induces insulin resistance and administration of melatonin to diabetes prone rats ameliorates their glucose metabolism. Furthermore loss-of-function mutations of the melatonin receptor gene are associated with insulin resistance and DM II in humans.Objective and hypotheses: So far the effec...

Introduction: Childhood obesity shows increasing numbers worldwide and presents as a global health issue due to multiple metabolic comorbidities. About 1 % of adolescents with obesity develop type 2 diabetes (T2D), however little is known about the genetic and pathophysiological background in young age. Genome-wide association studies in adults revealed genes with increased diabetes risk, most of them regulating insulin secretion. The objective of this study w...

Background: Subjects born small for gestational age (SGA) are at higher risk for metabolic, hormonal and reproductive problems later in life and about 2–10% of children born SGA do not catch-up in height. All these changes may influence bone mineral density (BMD).Aim: To evaluate hormonal profile and BMD in adolescents born SGA in comparison to their peers born appropriate for gestational age (AGA).Methods: 103 children were e...

Background: Subjects born small for gestational age (SGA) were shown to be at higher risk to later metabolic consequences but early prediction factors of changes in glucose metabolism are not clearly known.Objective and hypotheses: We aimed to investigate glucose tolerance and insulin resistance in adolescents born SGA or appropriate for gestational age (AGA) and their relationship with perinatal and postnatal factors.Method: A pro...

Background: GH promotes longitudinal growth and bone modeling/remodeling. The bone formation markers intact amino-terminal propeptide of type 1 procollagen (PINP), bone-specific alkaline phosphatase (BALP), and osteocalcin reflect different stages in bone formation, i.e. proliferation with collagen synthesis, matrix maturation, and mineralization.Objective: The purpose was to study the time course of different bone formation markers during GH treatment i...

Background: GH is secreted in a pulsatile manner. The resulting GH peaks are known to be associated with growth, whereas the trough levels between the peaks are thought to be associated with metabolism in different tissues. GH trough levels were identified as a metabolically active signal in rats in the 1980th leading to differences in fat patterning with central obesity. Obese children are known to have low bone mass and bone mass is reduced in short children.<p class="ab...

Background: The importance of vitamin D for skeletal health is well established and many recent reports indicate that vitamin D deficiency is linked to chronic diseases. Vitamin D status is defined by serum 25-hydroxyvitamin D (25(OH)D), and although there is no consensus on optimal levels of 25(OH)D concentrations of 50 nmol/l (20 ng/ml) meet the requirements in 97.5% of the population. In Sweden, sun cannot synthesize vitamin D during the winter, therefore supplementation is...
