Which of the following is an example of a secondary prevention program?

The distinction of secondary prevention programs lies in their focus on early detection and intervention to prevent the progression of disease, particularly for populations at risk for specific health issues.

The example of osteoporosis education classes for postmenopausal women is a secondary prevention program because it targets a specific group known to be at risk for developing osteoporosis. The aim of these classes is to educate participants about risk factors, prevention strategies, and behaviors that can help mitigate the onset of osteoporosis after they have potentially already developed some level of risk.

In contrast, routine screenings for colon cancer represent an early detection approach aimed at identifying cancer at its most treatable stage and is also a strong example of secondary prevention. A smoking cessation campaign is primarily a primary prevention strategy aiming to prevent the initiation of smoking. Nutrition classes for pregnant women focus on promoting healthy eating during pregnancy, a primary prevention effort aimed at improving overall maternal and infant health.

Thus, the choice of osteoporosis education classes for postmenopausal women exemplifies secondary prevention as it seeks to educate and empower individuals who are already at heightened risk for a specific health concern.
