Osteoporosis is a metabolic condition that leads to bone loss and increases the risk of bone fractures, often diagnosed only after a fracture has occurred. Although pharmacological measures are used for treatment, preventive measures such as regular physical activity, adequate intake of calcium and vitamin D, and avoidance of smoking and alcohol are key. With this work, I plan to conduct a survey on the level of knowledge about osteoporosis and knowledge of preventive measures of osteoporosis among the adult population. The aim of the survey is to collect data and investigate whether age, gender and level of education affect the level of knowledge among adults. The goal of the research is to make the public aware of the importance of implementing preventive measures before the first symptoms of the disease appear. The study involves 50 participants who are divided into three groups according to gender, age, and education level. The participants in the study are patients of the general medicine practice of Dr. Miro Bušljeta, who will fill out an anonymous survey during their visit to the doctor. The results showed that there were no significant differences in knowledge about osteoporosis between men and women, suggesting an equal distribution of health information between the sexes in this population. Also, no significant difference was found in the level of knowledge between people of mature age (20-59 years) and older people (60+ years), despite the higher frequency of osteoporosis in older age. However, a significant difference was obtained in the division of respondents by level of education. respondents with a higher level of education showed a significantly higher level of knowledge about osteoporosis and preventive measures. These results indicate that education is a key factor in understanding health problems and preventive measures.
