Which federal agency is a sub-agency of the CDC?

• A. OSHA
• B. National Institute for Occupational Safety and Health (NIOSH)
• C. Centers for Disease Control and Prevention (CDC)
• D. Environmental Protection Agency (EPA)

Answer: (B)

Organizational structure of federal public health agencies is what this question tests. The Centers for Disease Control and Prevention is a major agency within the Department of Health and Human Services and includes various institutes and centers. The National Institute for Occupational Safety and Health operates as a component of the CDC, focusing on research to prevent work-related injuries and illnesses and to provide guidance to improve occupational safety. It is housed under the CDC rather than being an independent agency or part of another department. By contrast, OSHA is part of the Department of Labor, not the CDC, and the Environmental Protection Agency is its own independent agency focused on environmental protection. So the sub-agency within the CDC is the National Institute for Occupational Safety and Health.
