Supplementation and Depressive Symptomatology Incidence Among Saudi Arabian Adults

Not Applicable

Completed

• Conditions: Vitamin D Deficiency; Depressive Symptoms
• Interventions: Dietary Supplement: Vitamin D supplementation

• Registration Number: NCT05916053
• Lead Sponsor: Lebanese American University

Brief Summary

The goal of this randomized controlled trial is to explore the relationship between Vitamin D supplementation and depressive symptomatology in Saudi Arabian Population.

The main questions it aims to answer are:

* Is Vitamin D deficiency associated with an increased prevalence of depressive symptomatology among Saudi Arabian Population?

* Is Vitamin D Supplementation for a period of 3-month at 50,000 International Units might be associated with an improved depressive status? All the participants were clients who attended the clinic to help with weight management - who were doing regular medical check-ups - at Al Themal Medical Center which is located in Abha, Saudi Arabia.

Participants were requested to do a general blood test to check for any vitamins and minerals deficiencies as part of the routine clinical procedure. This procedure did not incur any additional costs on the behalf of the participants. The participants who were identified to have any deficiencies were recommended to take supplements, also as part of the routine clinical procedure. Therefore, participants identified to be deficient or insufficient Vitamin D levels were screened and recruited to participate in the current study.

Participants were randomly assigned to either an interventional (vitamin D) or placebo group (control). The interventional group received vitamin D supplementation of 50.000International Units/week for 3 months and the placebo group received dietary advice and education on food sources of vitamin D for the same period. Both Groups received a weight gain or a weight loss diet as per their case.

At the three-months follow-up, the participants were readministered the face-to-face questionnaire and their blood levels for vitamin D were also checked.

Thus, this study would add value to the actions taken to treat vitamin D deficiency in Saudi Arabian adults. This might also assist in approaching new recommendations related to preventing or treating depression via vitamin D supplementation.
