Objective: This study aimed to assess the adherence and persistence to Calcium and vitamin D, and address the reasons of non-adherence. Methods: All patients attending a secondary care rheumatology clinic in a teaching hospital serving a multiethnic population, in the period between April and June fulfill the inclusion criteria. Patients were asked verbally before distributing the question air about the duration and reason of prescribed Calcium and vitamin D, only patients who are receiving Calcium and Vitamin D for duration of one year or more for purpose of osteoporosis management (treatment and prophylaxis) and are welling to participate in the question are were given the consent formand included in the study. Key finding: There was no statistically significant difference between calcium and vitamin D group in terms of adherence score (p = 0.175). About third of patients in both groups showed low adherence score; 31% (53/171), 38.2% (128/335) in calcium and vitamin D groups, respectively. Overall, there was significant difference in adherence score between age groups (p = 0.001). Low adherence score was mostly reported in young age group (18–39 years) for both medications but not related to level of education. Forget to take medication was the most reported reason of non adherence in both groups (29.5%, 89/302). Quarter of patients stated that multi-reasons contributed to their non adherence (24.8%, 75/302). Conclusion: Low adherence was high among both Calcium and Vitamin D groups (around third of both groups), however; there were no significant differences in medications adherence between the two groups.
