Which health issue category is most prominent in higher GDP populations?

• A. Non-Communicable Diseases
• B. Infectious Diseases
• C. Parasitic Diseases
• D. Waterborne Diseases

Answer: (D)

The pattern being tested is how disease burdens shift with development: in higher GDP populations, chronic non-communicable diseases become the most prominent health issue. As countries become wealthier, people live longer and lifestyle and environmental factors contribute to long-term conditions such as heart disease, cancer, diabetes, chronic respiratory diseases, and mental health disorders. Aging and lifestyle—habits like unhealthy diets, physical inactivity, smoking, and obesity—drive these illnesses, making them the dominant health concern.

In contrast, infectious diseases, parasitic diseases, and waterborne diseases are more common in lower-income settings where sanitation, vaccination, clean water access, and healthcare services are less developed. Those conditions decline as GDP and development improve, which is why they are less prominent in higher GDP populations.
