In a nutrition program, which example is a proximal measure?

• A. Daily fruit intake
• B. Body weight after six months
• C. Lipid profile
• D. Incidence of cardiovascular disease over years

Answer: (A)

Proximal measures capture immediate changes that the program can directly influence. Daily fruit intake fits this best because it is a direct behavior the nutrition program aims to change and can be tracked on a daily basis, showing whether participants are following the plan soon after implementation.

In contrast, body weight after six months is a health status outcome that reflects the cumulative effect of many factors over time, not just the program’s immediate actions. Lipid profile is a biomarker that can respond to dietary changes but typically requires sustained behavior changes and can be influenced by multiple variables, making it a more distal indicator than daily intake. Incidence of cardiovascular disease over years is a long-term health outcome, far removed in time from the program's actions.

So the daily fruit intake is the proximal measure because it directly measures the behavior the program targets and can show quick, near-term responsiveness.
