Which is an example of midstream public health practice?

• A. Screening for food insecurity
• B. Advocating for policy changes
• C. Building new hospitals
• D. Sanitation infrastructure

Answer: (A)

Midstream public health practice focuses on identifying individuals at risk and linking them to concrete resources within clinical or community settings. Screening for food insecurity fits this approach because it involves asking someone about their access to food and then connecting them to immediate supports, such as food assistance programs, social services, or targeted support, to reduce the immediate risk they face.

The other options operate at a broader, population level. Advocating for policy changes aims to alter laws or systems that affect large groups, which is upstream work. Building new hospitals and sanitation infrastructure are large-scale investments that change the environment or capacity of the health system, also considered upstream efforts.
