The goal of the this study is to create an interdisciplinary program which includes intervention in the fields of nutrition, physical activity and behavior in order to treat obesity and overweight among kindergarten children and to examine the influence of such program on the BMI,BMI%, physical fitness, knowledge and preferences in the said fields among the participants.

Subjects, goals and objective:

Obesity is the most common chronic children disease of the modern era. The number of children who suffer from obesity is increasing to scales of epidemic. The frequency of obesity among kindergarten children (ages of 2-5) in the United States is approximately 14%, whereas among children of those ages in the center of Israel there is a risk of 25% to obesity and overweight.

Obesity is not only a cosmetic problem but also constitutes the #1 risk factor for common medical problems, such as: hyperlipidemia, high blood pressure, glucose intolerance, type 2 diabetes, arteriosclerosis, asthma, orthopaedic problems and psychological problems. A comprehensive review that was recently published showed that among fat children, intensive intervention programs which include nutrition consulting, physical training and behavioral change are the most effective to treat obesity.

Children who suffer from obesity have a greater risk to become fat adults and the older the child the greater the risk becomes. Therefore, it is highly important to treat such obesity in the youngest age possible. Moreover, along with the change of nutritious preferences, a great emphasize should be given to physical activity in order to reduce the BMI percentage and improve the physical fitness.

The goal of the paper is to create an interdisciplinary program which includes intervention in the fields of nutrition, physical activity and behavior in order to treat obesity and overweight among kindergarten children and to examine the influence of such program on the BMI,%BMI, physical fitness, knowledge and preferences in the said fields among the participants.

Place: The intervention program will be held in the sports and health center for children and youth at "Meir" medical center.

The intervention group: 25 kindergarten children in the ages of 4-6 who defined as suffering from overweigh (BMI percentage 85-95) or obesity (above BMI percentage 95).

Non-generalization criteria: children who suffer from obesity due to organic disease or children who take medicine which may influence body weight (e.g., steroids) will be excluded from the research.

The control group: 25 kindergarten children in similar ages who defined as suffering from overweigh (BMI percentage 85-95) or obesity (above BMI percentage 95) and who do not participate in any intervention program.

The research plan Nutritious plan: includes 6 personal meetings, 30-45 minutes each, of the child and his parents with a dietician from the center. The meetings will include nutritious evaluation and will focus on nutritious education.

Physical activity: physical trainings of 45 minutes each will be held twice a week and be guided by a qualified trainer. In order to encourage the participants to take responsibility for the process, the children will be asked to further practice during the weeks and conduct little assignments which will be given by the trainer.

Additionally, all the participants will take part it a 45 minutes meeting of movement therapy once a week. Such meeting will be held by a qualified trainer. The goal of such meeting is to strengthen nutritious and physical activity habits and to assimilate positive change in the participants' lifestyle.

Evaluation index: height, weight, BMI and BMI percentage,"nutrition and physical activity knowledge and preferences" questionnaire. The questionnaire is an instrument to evaluate the knowledge and preferences of children in the ages of 4-8 in the fields of nutrition and physical activity.

Evaluation of physical fitness: "back and forth" running test for a 10m distance.

Inclusion Criteria:

• children in ages of 4-6 who defined as suffering from overweigh (BMI percentage 85-95) or obesity (above BMI percentage 95).

Exclusion Criteria:

• children who suffer from obesity due to organic disease or children who take medicine which may influence body weight (e.g., steroids) will be excluded from the research.
