About the presentation
The Bergen Growth Study 1 (BGS1) was conducted in the Bergen county in 2003-6 and recruited 8299 children and adolescents aged 0-19 years. The BGS1 database includes cross-sectional measurements of 10 anthropometric traits, a second time measurement, one year later, of height and weight in primary-school-aged children, and parental questionnaire data. The current national growth references are based on these data. Further, the study has given insights into the problem of overweight and obesity among Norwegian children and adolescents. The BGS2 is focused on pubertal development, was conducted in 2016 and includes data from 1172 children aged 6-16 years. In addition to the traditional Tanner pubertal stages, more objective ultrasound measurements were performed of the girls glandula mammae and the boys testicles. Blood and saliva samples were collected and parents answered a questionnaire. References for pubertal development among Norwegian children and adolescents are now being constructed.
