Fractures in the elderly and vitamin D

Area of Science:

• Gerontology
• Nutritional Science
• Bone Biology

Background:

• Aging increases fracture risk, often linked to reduced bone mineral density.
• Nutritional factors like calcium and vitamin D are vital for skeletal maintenance but often inadequate in the elderly.
• Reduced sun exposure and mobility contribute to vitamin D deficiency in older populations.

Purpose of the Study:

• To highlight the prevalence and skeletal consequences of vitamin D deficiency in the aging population.
• To emphasize the dual role of vitamin D in bone mineralization and mineral homeostasis.
• To advocate for the diagnosis, treatment, and prevention of vitamin D deficiency in the elderly.

Main Methods:

• Review of established knowledge on aging, bone health, and vitamin D metabolism.
• Analysis of the skeletal effects of vitamin D, including its impact on parathyroid hormone and bone resorption.
• Examination of age-related changes in vitamin D absorption, metabolism, and action.

Main Results:

• Vitamin D deficiency is prevalent in the elderly, contributing to osteoporosis and osteomalacia.
• Aging impairs vitamin D absorption, activation, and cellular response.
• Inadequate vitamin D exacerbates calcium deficiency, leading to poor bone mineralization and increased bone resorption.

Conclusions:

• Vitamin D deficiency significantly impacts skeletal health in the elderly, increasing fracture risk.
• Correction of vitamin D deficiency is an accessible intervention with substantial benefits.
• Public and clinical education is essential for the diagnosis, treatment, and prevention of vitamin D deficiency in older adults.
