With a growing number of public health challenges and a recognized need to address the root causes of health outcomes, local health departments (LHDs) have been using health impact assessment (HIA), and other Health in All Policies (HiAP) approaches, to work strategically and innovatively with non-traditional partners to promote and protect the public’s health by informing decision outcomes that do not routinely consider health. HIA provides a structured framework to integrate health considerations in proposed policies, programs, and plans. LHDs are important partners in HIA practice in the United States. Currently, a third of all HIAs are led by or involve a LHD.1 The National Association of County and City Health Officials (NACCHO) has had a long history of supporting efforts to promote HIA practice at LHDs.
