Area of Science:

  • Human biology
  • Nutritional science
  • Developmental biology

Background:

  • Trace minerals are vital for human health, influencing growth, immunity, and cognitive functions.
  • Deficiencies in essential trace elements like iron and zinc can have significant adverse effects on development across various life stages.

Purpose of the Study:

  • To review the mechanisms and evidence linking trace mineral deficiencies to impaired biological functions.
  • To examine the specific impacts of zinc and iron deficiencies on growth and psychomotor development.

Main Methods:

  • Literature review of studies on trace mineral deficiencies.
  • Analysis of human and animal model data on zinc and iron's role in development.
  • Examination of effects across different age groups from fetal life to adolescence.

Main Results:

  • Iron deficiency impacts psychomotor development but shows no significant effect on physical growth.
  • Zinc deficiency is associated with growth retardation and delays in psychomotor development.
  • Other trace minerals like copper, manganese, selenium, and iodine also play roles in development.

Conclusions:

  • Iron and zinc deficiencies pose risks to child development, affecting cognitive and physical milestones.
  • Understanding these deficiencies is crucial for public health interventions aimed at optimizing child growth and development.
