Background and objectiveAdolescence obesity and overweight is one of the most common health problems in Iran. This study aimed to determine the effect of education based on precede model in education of nutrition and physical activities in obesity and overweight female high school students of Fasa city, Fars Province, Iran in 2017–2018. Materials and methodsThis research is a quasi-experimental study performed on 200 overweight and obese high school female students who were randomly assigned to two groups of control and experimental.
