Which of the following is NOT listed as a preventive behavior?

• A. Regular screening
• B. Non-smoking
• C. Avoidance of overweight
• D. Moderate exercise

Answer: (A)

The key idea is differentiating primary prevention from other health actions. Preventive behaviors in this context mean actions that reduce the risk of developing disease in the first place. Regular screening, while essential for catching disease early, serves to detect disease after it may have started and is classified as secondary prevention rather than a primary preventive behavior. The other options—non-smoking, avoiding overweight, and engaging in moderate exercise—are classic primary prevention actions because they directly lower risk factors and help prevent disease from developing. Therefore, regular screening is not listed as a preventive behavior in this framing.
