Vitamin A deficiency elimination is a global health priority. Newer methods detect subclinical deficiency, crucial for preventing severe infections in children and achieving public health goals.

Area of Science:

  • Public Health
  • Nutrition Science
  • Global Health

Background:

  • Vitamin A deficiency (VAD) elimination is a key global health objective.
  • Subclinical VAD affects 5-6 times more children than clinical VAD in developing nations.
  • Subclinical VAD increases the risk of severe and fatal infections in children.

Purpose of the Study:

  • To highlight the significance of subclinical vitamin A deficiency.
  • To emphasize the need for early detection and intervention strategies.
  • To inform policy and planning for VAD elimination.

Main Methods:

  • Utilizing newer methodological approaches for detecting subclinical deficiency.
  • Analyzing population-level data to understand the scope of the problem.
