Overview

Micronutrient deficiencies are health conditions that result from inadequate intake, absorption, or utilisation of essential vitamins and minerals required in small amounts for normal physiological function. Common deficiencies involve vitamin A, iron, zinc, iodine, folate, and the B vitamins, and they are sometimes described as "hidden hunger" because they can occur even when overall energy intake appears sufficient. These deficiencies are a major focus of nutrition science and public health because they impair growth, immunity, cognition, and reproductive outcomes, and disproportionately affect children, adolescents, and pregnant women, particularly in low-resource settings. Research published under this topic examines the social and economic determinants of deficiency, including household economic status and childhood micronutrient status, as well as dietary diversity and nutritional status among adolescent and pregnant women. Specific clinical presentations are also addressed, such as vitamin B12 deficiency in children, ocular manifestations of vitamin A deficiency, and nutritional deficiencies arising after bariatric surgery, including Wernicke encephalopathy following sleeve gastrectomy. Further studies explore the delivery and utilisation of nutrition services, awareness of nutrition during pregnancy, field methods for nutritional assessment, and the broader links between food security, climate, and land degradation. Collectively the articles emphasise assessment, prevention, and management of deficiencies across the life course and in varied geographic contexts.
