Which of the following is an example of an outcome status indicator used to measure the impact of interventions on population health?

• A. Child regularly attends school
• B. Child's favorite toy
• C. Number of snacks per day
• D. Color of classroom walls

Answer: (A)

Outcomes measure the actual effects of an intervention on how people function or feel, reflecting changes in health status or everyday participation. Regular attendance at school fits this idea because it shows a child’s ability to participate in daily life and learning, which tends to improve when health and well-being improve. It’s a tangible, population-level signal that health-related interventions can produce a positive change in functioning and social participation.

The other options don’t capture this end result. A favorite toy is a matter of preference, not health status. The number of snacks per day tracks intake or eating habits rather than the health outcome after an intervention. The color of classroom walls is an environmental condition, not a measure of health impact.
