ABSTRACT
Puberty as a stage of life is an important developmental process. Teen girls have numerous health care needs and their specific issues should be considered. This study mainly aimed to determine the impact of education based on health belief model on promotion of physical puberty health among female teenagers who were residents in welfare boarding centers in Tehran city. It was a quasi-experimental intervention study, conducted in welfare boarding centers of Tehran city among inhabitant girls with 12 to 19 years old. All eligible persons were selected [n=61]. Data collection tool was a questionnaire including demographic information, health belief components, physical function during menstruation, completed before and one month after training by interview. Educational intervention was implemented in 3 months. Data was analyzed by Wilcoxon statistical test using SPSS16 software. After educational intervention, perceived severity [p<0.001], perceived susceptibility [p<0/001], perceived barriers [p<0.001], perceived benefits [p<0.001], and physical function during menstruation were significantly different. Educational intervention improved girls' perceptions and performance. Thus, health belief model should be used for puberty health education planning in female adolescents
