What was the main finding of the study by Sallis et al. in 1999 regarding college-based health education?

The study by Sallis et al. in 1999 highlighted the separation between knowledge acquisition and actual behavioral changes among college students regarding health education. The main finding indicates that while health education programs effectively enhanced students' knowledge about healthy behaviors, this increase in knowledge did not necessarily translate into changes in behavior. This illustrates a critical aspect of health education: knowing what is healthy does not always lead to actions that reflect that knowledge. This gap emphasizes the complexity of behavior change, which can be influenced by various factors beyond just education, such as personal motivation, societal norms, and environmental influences. Understanding this distinction is essential for developing more effective health education strategies that not only inform but also promote positive behavioral changes.
