Which activity exemplifies the policy development core function in public health?

The activity of drafting safety regulations for hazardous chemical use exemplifies the policy development core function in public health because it involves formulating policies and guidelines that aim to protect community health and safety. Policy development focuses on the creation of laws, regulations, and procedures that help manage public health concerns and guide actions to improve community well-being.

In this case, by developing safety regulations, public health professionals are actively engaging in a critical step of the public health framework, which aims to mitigate risks associated with hazardous substances, ensuring that environmental health standards are met and protecting individuals and populations from harm.

While conducting surveys on community health, performing health screenings, and providing health education workshops are all essential public health activities, they primarily fall under assessment and assurance functions rather than policy development. Surveys are tools for gathering data to understand health status, health screenings are direct health services, and health education workshops are aimed at improving awareness and promoting healthy behaviors, but they do not involve the formulation of policies that govern public health practices directly.
