Strenghtening parenting styles and practices in existing interventions to prevent overweight and obesity in children.

The purpose of this cluster randomized study is to investigate whether the eating and exercise behaviors of children between 9 and 12 years at the school participate in the intervention 'Scoring for health' is healthier if the parents of these children home an E-learning follow, compared with children whose parents only receive a leaflet about healthy eating and exercise.

In the E-learning we teach parents how they can encourage their child to eat healthier and exercise and solving conflicts about these topics by using parenting skills and practices.

After completion of the E-learning by parents:

1. Eating an physical activity behaviour of children of these
parents are healthier than children of parents in the control
group. With healthier eating and exercise habits we mean:

A. The children meet breakfast, fruit and vegetable standards;

B. The kids drink 2 or less sweet drinks per day;

C. The children meet the standard move;

D. The kids computer and / or watch less than 2 hours of TV per day.
