Overview

Vitamin B12 deficiency occurs when the body lacks sufficient cobalamin, an essential nutrient required for red blood cell formation, neurological function, and DNA synthesis. Research published in the International Journal of Nutrition examines this deficiency across diverse populations and clinical contexts. Studies have documented vitamin B12 deficiency in children resulting from inadequate dietary intake, particularly in hospital settings, and have explored the relationship between household economic status and micronutrient deficiencies including B12 among children in national surveys. The journal has published investigations into nutritional deficiencies that develop during pregnancy following bariatric surgery, a known risk factor for B12 malabsorption. Additional research has addressed the broader role of nutrients in chronic conditions such as diabetes, where B12 status may be relevant, and has examined nutritional status assessments in women and children that include micronutrient evaluation. The journal has also featured work on vegetarianism in dietary guidelines and complementary feeding recommendations, contexts in which B12 adequacy requires particular attention due to the vitamin's primary occurrence in animal-source foods. This body of research underscores the clinical and public health significance of identifying and addressing vitamin B12 deficiency across different age groups and dietary patterns.
