Prevalence of Obesity and Overweight in Primary School Children in the Rhein-Neckar Region in Germany

Overview

The study will determine the weight status in primary school children in the Rhein-Neckar Region in Germany and will analyse the development of height and weight in these children during the time of COVID-19 related restrictions by asking parents to provide data from childhood examinations. Additionally, interactions between cognitive abilities and weight-status will be studied.

Detailed Description

The prevalence of obesity and overweight is increasing among both adults and children. School and kindergarten closings during the COVID-19 epidemic may have had an additional negative impact on the weight development of the affected children. This study aims to examine the post-lockdown prevalence of overweight and obesity in school children in the second grade in the Rhein-Neckar Region in Germany and look at possible lockdown effects. Additionally, interactions between cognitive abilities and weight-status will be studied. Anthropometric measurements, interviews as well as cognitive testing will be performed in schools in the summer of 2021 in children in the first grade (class 2020/2021). Parents will be asked to provide measurements from U-childhood-examinations and complete a 3-day food record. The local health authority (Gesundheitsamt) will assist in making a representative selection of schools from different socioeconomic areas and provide data from the pre-school examinations. Collected data will be analyzed and compared to national and international surveys, evaluating the trends of the children's height and weight development. Weight status will be assessed by calculating z-BMI standardized for age and compared with national and international growth charts using both national and WHO classification. Potential interrelation between weight-status, weight development with cognitive performance will be explored. The study will be able to deliver valuable insights in regards to the health of school children in the Rhein-Neckar Region as well as evaluate the effect of COVID-19 related lockdowns on their health.
