[Rickets in Asian immigrants]

Area of Science:

• Nutritional science
• Pediatrics
• Public health

Background:

• Rickets is thought to be rare in developed nations, but vitamin D deficiency is increasing among immigrant populations.
• Studies indicate high rates of rickets and osteomalacia in Asian immigrants, including infants, adolescents, and pregnant women, relocating to cooler climates.
• Environmental and sociocultural factors, such as reduced sunlight exposure and inadequate calcium intake, are primary drivers of this vitamin D deficiency disorder.

Purpose of the Study:

• To review the prevention and treatment of rickets and osteomalacia in Asian children and adolescents immigrating to Spain.
• To address the rising incidence of vitamin D deficiency and related bone disorders in this vulnerable population.

Main Methods:

• Review of existing literature on rickets, osteomalacia, and vitamin D deficiency in immigrant populations.
• Analysis of environmental, dietary, and sociocultural factors contributing to the condition.
• Assessment of current prevention and treatment guidelines relevant to Asian children and adolescents in Spain.

Main Results:

• Immigrant populations, especially from Asia, face a significant risk of vitamin D deficiency rickets and osteomalacia.
• Low sunlight exposure and dietary calcium insufficiency are key etiological factors.
• The incidence of these conditions is rising in Spain due to increased immigration.

Conclusions:

• There is a critical need to re-evaluate and enhance strategies for preventing and treating rickets and osteomalacia in Asian children and adolescents residing in Spain.
• Public health initiatives should focus on addressing nutritional deficiencies and promoting adequate vitamin D intake within immigrant communities.
