Question: 1 / 400

What type of approach to prevention aims to address the primary sources of a health problem by 'moving upstream'?

Primary prevention

Secondary prevention

Tertiary prevention

A public health approach

A primary prevention approach focuses on preventing a health problem from occurring in the first place, while a secondary prevention approach focuses on early detection and intervention. Tertiary prevention aims to reduce the impact of an already established health problem. A public health approach, on the other hand, involves targeting the underlying causes and risk factors of a health problem in order to prevent it from occurring. This corresponds to the concept of 'moving upstream' by addressing the source of the problem rather than just the symptoms. So while the other approaches may also contribute to prevention efforts, a public health approach is the most direct and effective way to address the primary sources of a health problem.
