What this trial studies

This study aims to address childhood obesity by implementing healthy school lunches in primary schools in Rotterdam, where many children currently do not have access to nutritious meals. It will evaluate the effectiveness and feasibility of this intervention through a prospective, single-center, cross-over design with three measurement moments. Data will be collected on the impact of the healthy lunches on children's diets and overall health, as well as feasibility through questionnaires for teachers. The participating schools are part of the 'Enjoy Being Fit!' program and have a high prevalence of overweight and obesity among students.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 4-12 years attending primary schools in Rotterdam that participate in the 'Enjoy Being Fit!' program and have a high deprivation score.

Not a fit: Children from schools that do not meet the inclusion criteria or those who already have access to healthy school lunches may not benefit from this study.

Why it matters

Potential benefit: If successful, this initiative could significantly improve children's dietary habits and contribute to reducing obesity rates in the target population.

How similar studies have performed: Previous research has shown positive effects of healthy school lunch programs, indicating that this approach has potential based on existing evidence.
