About this study

Official title: CrescNet - Computer-guided, Population-based Surveillance System for Growth Disorders

CrescNet is a network of primary care physicians and pediatricians (n=219) and endocrinological treatment centers (n=33), established in Leipzig in 1998, whose aim is to improve the early detection of growth disorders. Secondary to this clinical aim, epidemiological analyses, for example on secular trends of growth data of children, are performed.

Read the detailed description

Pediatricians participating in CrescNet provide pseudononymized data on patients' height, weight, and head circumferences to the CrescNet registry. Growth data are evaluated by automatized filter algorithms and by a pediatric endocrinologist. CrescNet does not have access to patients or personal patient data. Each participating pediatrician receives a quarterly screening report with recommendations for the work-up of children with abnormal growth or abnormal development of weight or body mass index.

The data registry is used for scientific purposes.The collection of data from healthy children allows the generation of evidence based statements about prevalence rates of growth disorders and also about the rates in disorders of weight development. For this, data are provided completely anonymized without allowing conclusions on personal patient data.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. growth disorders

    Early detection of growth disorders in childhood and adolescent development. For this, not only absolute data but also growth velocity data are evaluated.

    Measured: 18 years

  2. obesity

    detection of critical age periods for the development of obesity. For this, not only absolute data but also growth velocity data are evaluated.

    Measured: 18 years
