Randomized, controlled, open, comparative intervention study in 270 children at risk for obesity.~Objectives:~To develop an intervention program for obesity prevention in children aged 5-10 years old, who are at risk to develop obesity~To compare between the efficacy of two different intervention programs and a control group in preventing obesity in the short and the long term.~To evaluate the role and significance of including parents in an intervention program for obesity prevention.~To identify demographic parameters, lifestyle characteristic and biochemical markers that predict the risk of developing obesity and the response for treatment.~Randomization:~Patients will be randomly allocated into one of two intervention groups or control group in ratio of 1:1:1. Each group will contain 12-15 participants.~Intervention groups:~parent's group- only parents will take part at the intervention program.~Parents and children group- both children and parents will take part at the intervention program, in two separate sessions.~Methods:~The study will be consist of two main periods: an intervention period of 3 months followed by 21 months of a follow up period. During the intervention period, participants (parents or both parents and children, depending on randomization) will attend a behavior intervention program once a week, each session will last one hour and would be guided by dietician and psychologist. Follow up visits will be performed at the clinic (for participants in all 3 groups) at months 0, 3, 12 and 24.~Height, weight, fat mass and waist circumference will be measured at 0, 3, 12 and 24 month. Height and weight of parents will also be measured at these visits.~Physical examination will be performed at 0, 3, 12 and 24 month.~Psychological and nutritional questionnaire (depression, quality of life and self estimation) will be filled at 0, 3, 12 and 24 month.~Fasting blood tests for: chemistry, hematology, lipids, glucose, insulin, TSH, adiponectin, IL-6 and TNFα will be performed at 0, 3, 12 and 24 month.
