Area of Science:

• Nutritional Science
• Psychiatry
• Public Health

Background:

• Vitamin D influences over 200 genes and is crucial for overall health.
• Vitamin D deficiency is linked to major health issues including cardiovascular diseases, diabetes, malignancy, and multiple sclerosis.
• This study investigates the association between vitamin D levels and depression.

Purpose of the Study:

• To determine vitamin D levels in individuals.
• To assess the association between vitamin D levels and depression.
• To identify demographic factors influencing vitamin D deficiency in relation to depression.

Main Methods:

• Vitamin D levels were measured in 200 subjects (100 healthy, 100 depressed).
• Subjects were screened using the Beck Depression Inventory (BDI) and categorized by age (≤20, 21-60, ≥61 years).
• Vitamin D status was compared between healthy and depressed groups across different age strata.

Main Results:

• A higher prevalence of vitamin D deficiency was observed in the Peshawar region.
• Depression was found to be common in individuals with vitamin D deficiency.
• Mild vitamin D deficiency was noted in depressed subjects compared to sufficient levels in healthy individuals.

Conclusions:

• A high frequency of vitamin D deficiency exists among depressed individuals in Peshawar, Pakistan.
• Vitamin D deficiency is more prevalent in females than males within the depressed cohort.
• Further research is needed to explore the cost-effectiveness of vitamin D supplementation for depression prevention and treatment.
