Swiss Childhood Health and Nutrition Survey 2023

Completed

• Conditions: Childhood Obesity

• Registration Number: NCT05697367
• Lead Sponsor: Isabelle Herter-Aeberli

Brief Summary

This study will repeat previous studies done in 2002, 2007 2012 and 2017/18, in order to monitor the trend in the prevalence of overweight and obesity in 6-12 year old children in Switzerland over the entire period. Furthermore, additional risk factors will be assessed for the later development of NCD using a questionnaire comparable to the one used in 2017/18.

Detailed Description

A total of ca. 2500 children will be recruited throughout Switzerland and their height, weight, waist circumference as well as percentage body fat will be measured. In addition, children will be asked to complete a questionnaire on some aspects of their diet, physical activity, health and socioeconomic background. Data will be compared to previous surveys conducted since 2002 to monitor trends in overweight and obesity prevalence in Switzerland. The results from the questionnaire will be used to investigate risk factors for obesity and the later development of NCDs.
