Knowledge and Awareness of the Relationship Between Vitamin D Deficiency and Depression Among a Sample of Adults in Saudi Arabia

This study found that both vitamin D deficiency and depression are common among the population in Saudi Arabia. Many participants believed their experience of depression was linked to vitamin D deficiency, although this was based on self-reported perceptions rather than clinical diagnoses. While general awareness of vitamin D sources and benefits was relatively high, understanding of its broader health impacts was relatively low. The study also identified gender and nationality as important factors associated with vitamin D deficiency. Health professionals should incorporate structured patient education initiatives, such as dedicating an additional five to 10 minutes during clinical appointments to discuss vitamin D's role in mental and physical health and developing informational brochures to be distributed in clinics and pharmacies.
