Osteoporosis is a condition where bones become weak and fragile, increasing the risk of fractures. To prevent and manage this condition, doctors often recommend supplements like calcium and vitamin D. However, many patients do not take these supplements as prescribed, which reduces their effectiveness and raises the chance of fractures. This study aims to find out how many patients stick to their calcium and vitamin D supplements and what barriers prevent them from doing so. The study will also test if regular follow-up visits with healthcare providers every three months can improve adherence to these supplements. Patients diagnosed with osteoporosis or osteopenia (weaker-than-normal bones) will be enrolled and followed for one year. During this time, their adherence to the prescribed supplements will be measured using simple tools, including questionnaires and tracking the amount of medication they use. The study will also identify factors like personal preferences, side effects, or other challenges that may affect their adherence. By understanding these barriers and testing ways to improve compliance, this research hopes to provide better strategies to help patients take their supplements regularly. This could reduce the risk of fractures and improve the overall health of people with osteoporosis. Participants can join voluntarily and may withdraw at any time without affecting their treatment. Their information will be kept confidential. Findings from this study will be shared in scientific journals to help improve care for osteoporosis patients worldwide.
