The “11 for Health in Denmark” intervention in 10‐ to 12‐year‐old Danish girls and boys and its effects on well‐being—A large‐scale cluster RCT

Abstract

The intervention program had a positive between-group effect on physical well-being in girls, whereas the change was not significant in boys. The overall scores for peers and social support improved during the intervention period, but no subgroup differences were found.
