Pediatric vitamin D and calcium nutrition in developing countries

Area of Science:

• Nutritional Science
• Pediatric Health
• Public Health

Background:

• Over one billion people have insufficient vitamin D levels, and calcium deficiency is prevalent in developing nations.
• Nutritional rickets is the most common non-communicable childhood disease globally, stemming from vitamin D and/or calcium deficiencies.
• Vitamin D deficiency is increasingly associated with non-skeletal health issues.

Purpose of the Study:

• To highlight the global prevalence and clinical diagnosis of nutritional rickets.
• To emphasize the importance of vitamin D and calcium in preventing and treating rickets.
• To identify areas for future research in understanding and managing rickets.

Main Methods:

• Clinical diagnosis of rickets based on physical examination (limb deformities, beaded ribs, widened wrists/ankles) in resource-limited settings.
• Review of existing knowledge on the causes, prevention, and treatment of nutritional rickets.
• Identification of research gaps in epidemiology, diagnosis, and intervention strategies.

Main Results:

• Nutritional rickets is a widespread childhood disease caused by deficiencies in vitamin D and/or calcium.
• Clinical diagnosis is feasible even without advanced laboratory or radiological tools.
• Prevention strategies include increased sun exposure and dietary improvements; treatment requires adequate vitamin D and calcium supplementation.

Conclusions:

• Early clinical recognition and intervention are vital for managing nutritional rickets.
• Further research is essential to address epidemiological, diagnostic, and therapeutic challenges, particularly in developing countries.
• Long-term consequences of childhood vitamin D and calcium deficiencies require further investigation.
