摘要:This study was conducted to determine the impact of education using the Health Belief Model on preventing osteoporosis among female students. This interventional study (quasi-experimental) was performed on 45 female students aged 15–16 years old who resided in a town near Tehran. The females participated in a three- week educational programme based on the Health Belief Model. The data collection instrument was a validated and reliable questionnaire in five sections demographics, knowledge, Health Belief Model constructs, physical activity and consumption of foods containing calcium. The mean scores of students' knowledge were significantly different before and after the educational intervention (P < 0.05). The mean scores of some Health Belief Model structures changed significantly after the intervention (P < 0.05). Also post-intervention, physical activity increased (P = 0.041) but calcium intake did not. The use of an educational intervention on osteoporosis seems to improve knowledge and health beliefs and may positively impact physical activity–related behaviour.
