Our study was embedded in the outcome evaluation of the health promotion program “Join the Healthy Boat”. This program includes health promotion in the curriculum of grades one to four at primary school and combines behavioral and environmental components. Children are empowered to make healthy choices in terms of physical activity, consumption of sugar sweetened beverages, and use of screen media. The aim of the present study is to look at factors that are associated with skipping breakfast in schoolboys and -girls in order to improve preventive and health promoting measures and to help respective multicomponent interventions to reach their goal of promoting healthy weight in children.
