Background and Objective: Obesity is known to affect pubertal timing. However, existing data are still controversial, observing either delayed or accelerated pubertal onset, especially among boys. Herein, we evaluated pubertal milestones and underlying hormonal changes between lean and obese children.Material and Methods: We examined 13,484 events from 4,855 lean (BMI SDS <1.28) and 1,983 obese (BMI SDS > 1.88) c...

Context: Childhood obesity is supposed to affect growth and development in children but there is uncertainty with regard to dynamics and potential causes. We analyzed differences in age-related growth patterns of obese and normal-weight children and their association with circulating endocrine and metabolic factors.Objective/Design: In a large German childhood cohort from Leipzig including 7986 children (22793 data sets) we compared cross-sectional and l...

Here we identified and characterized a heterozygous tandem duplication at the ASIP (agouti-signaling protein) gene locus causing ubiquitous, ectopic ASIP expression in a female index patient with extreme childhood obesity. In patient-derived adipose tissue samples, we observed pronounced differentiation of stroma-vascular fraction (SVF) cells into adipocytes in the patient compared to normal control cells. We further found reduced mitochondrial maximum respir...
