Which screening option is better for communities with historically low incidence of anemia and generally good infant dietary practices?

• A. Selective Screening
• B. Universal Screening
• C. Both
• D. Neither

Answer: (A)

In populations where anemia is uncommon and infants generally have good iron intake, screening everyone isn’t the most efficient use of resources. The yield of universal screening drops when the condition is rare, leading to more false positives, unnecessary follow-ups, and added costs without substantial benefit. Targeting screening to those with identifiable risk factors or signs of possible iron deficiency—selective screening—focuses effort where the chance of finding anemia is higher. This approach improves how useful each test is and makes better use of resources while still identifying infants who truly need intervention.
