Vitamin D and health status in elderly

Area of Science:

• Gerontology
• Nutritional Science
• Endocrinology

Background:

• Vitamin D deficiency is a widespread issue across all age groups.
• Vitamin D receptors are present in numerous organs and tissues, highlighting its broad biological relevance.
• Elderly individuals face elevated risk due to reduced outdoor activity, thicker skin, and impaired kidney function.

Purpose of the Study:

• To review the key characteristics of vitamin D.
• To outline the clinical implications of vitamin D deficiency (hypovitaminosis D) specifically in the elderly population.
• To emphasize the importance of oral vitamin D supplementation for geriatric health.

Main Methods:

• Literature review of epidemiological studies on vitamin D.
• Analysis of the physiological roles of vitamin D and its receptors.
• Examination of the health consequences of vitamin D deficiency in older adults.

Main Results:

• Vitamin D deficiency significantly affects the musculoskeletal, cardiovascular, and renal systems in the elderly.
• Hypovitaminosis D is linked to increased risk of type II diabetes, cancer, and cognitive decline.
• The review details the clinical manifestations and pathological conditions associated with low vitamin D levels.

Conclusions:

• Vitamin D plays a critical role in maintaining health throughout the lifespan, particularly in the elderly.
• Addressing vitamin D deficiency through supplementation is essential for preventing and managing various age-related diseases.
• Maintaining adequate vitamin D levels is a key strategy for promoting healthy aging and improving quality of life in geriatric populations.
