Based on the World Health Organization’s global school health initiative this study investigated intervention effects of statewide health promotion in schools on the numbers of children’s sick days and visits to a physician, and parental days off work due to child illness.
School-based health promotion slightly reduces sick days in first grade children. Subsequently, parents may not need to stay off work themselves. Small individual effects add up to larger benefits in a statewide implementation of health promotion. Additionally, health promotion may also positively contribute to school success.
