The Effect of a Patient Education Program on Vitamin D Levels and Health Beliefs Regarding Vitamin D Use

Background and Rationale: Vitamin D deficiency is a major public health concern. While clinical guidelines provide treatment protocols, medication adherence remains a significant barrier to achieving target serum levels. This study aims to evaluate whether a structured patient education program can improve health beliefs and adherence, ultimately leading to better clinical outcomes. Study Procedures: Participants identified with Vitamin D levels \<30 ng/mL will be randomized into two groups. Intervention Group: Patients will receive a face-to-face education session covering the importance of Vitamin D, correct usage, and potential side effects. They will also receive informative brochures and monthly follow-up phone calls to support adherence. Control Group: Patients will receive standard clinical care without additional structured education.Evaluation:Adherence will be monitored using the Medication Possession Ratio (MPR). Serum 25(OH)D levels and Vitamin D Health Belief Scale scores will be reassessed at the 6-month mark to compare the effectiveness of the intervention against the control group.

Inclusion Criteria: * Female, * Aged 18 years and older, * Hypothyroid disease, * Serum vitamin D level \< 30 ng/mL, * Providing written informed consent to participate in the study. Exclusion Criteria: * Male , * Under the age of 18, * Patients who do not provide written informed consent, * Serum vitamin D levels \> 30 ng/mL
