Relation between vitamin D and geriatric syndrome

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Vitamin D deficiency is a prevalent issue among the elderly population.
• Low serum vitamin D levels are associated with reduced physical performance.
• Deficiency is linked to increased risks of cognitive impairment, depression, and anxiety in older adults.

Purpose of the Study:

• To investigate the relationship between vitamin D status and the prevalence of geriatric syndromes.
• To identify specific geriatric syndromes associated with low vitamin D levels in elderly individuals.

Main Methods:

• A prospective study involving 50 elderly participants (age > 65).
• Assessment included medical history, physical examination, serum 25-hydroxyvitamin D (OH)D levels via ELISA.
• Geriatric syndromes evaluated using Timed Up & Go test, Mini-Mental State Examination (MMSE), Geriatric Depressive Scale, Mini Nutritional Assessment, and POMA.

Main Results:

• 11 participants were vitamin D deficient (<12 ng/ml), 24 insufficient (12-20 ng/ml), and 15 sufficient (>20 ng/ml).
• Low vitamin D showed significant association with female gender, advanced age, lack of sun exposure, and nursing home residency.
• Significant positive correlations were found between low vitamin D and poorer performance on the MMSE (p=0.006) and Geriatric Depressive Scale (p=0.002).

Conclusions:

• Vitamin D deficiency is correlated with advanced age, cognitive dysfunction, and depression in the elderly.
• These findings highlight the importance of monitoring vitamin D levels in older adults.
• Further research may explore interventions to improve vitamin D status and mitigate associated geriatric syndromes.
