title: Adverse outcomes of poor micronutrient status in childhood and adolescence.
abstract: The adverse effects of micronutrient deficiencies and excesses in children up to reproductive age are presented. A summary of risks and adverse functional and health outcomes associated with deficient and excessive intakes and nutrition status of iron, iodine, zinc, vitamins A and D, folate, vitamin B12, and riboflavin is presented. Nutrient-nutrient interactions of micronutrients, age, gender, and other host and environmental conditions, such as pregnancy, genetic conditions, overall nutrition, force of infection, and social conditions are considered as covariates in trying to define causation and outcomes due to specific micronutrients. The outcomes analyzed focus on growth and development, mental and neuromotor performance, immunocompetence, physical working capacity, morbidity, and in the case of pregnancy, overall reproductive performance. The results presented include responses to specific and multiple "experimental" interventions. A brief analysis of possible public health programs is presented, with emphasis on prevention.
