BackgroundMajor infrastructure development is often transformative for society, including its health. In this realm, there is a growing trend to view airports as drivers for health. By linking airport, urban and health planning, airports can become settings for health. Engaging stakeholders and those affected by such major change in health assessments is essential. This paper demonstrates that health and health equity impacts of major infrastructure developments such as airports extend to the planning processes for these developments; it argues that building a Healthy Airport requires greater consideration of how communities are engaged in these processes. MethodsWe carried out a Health Impact Assessment of community engagement practices for the planning processes of a new greenfield airport in Australia. The standard step-wise process for completing an HIA was followed. Results151 stakeholders participated in the study. Overall, participants were dissatisfied with community engagement for the proposed airport. While there were some unanticipated positive community level impacts resulting from the engagement process (community members becoming involved in community activism), by and large community members identified mostly negative impacts including anxiety, disempowerment, poor social connection, lack of trust and aggravation of health inequities. ConclusionPotentially affected individuals and communities may feel disenfranchised by transformative infrastructure change ‘over their heads’. Missed opportunities to achieve benefits of well-executed community engagement not only lead to feelings of disempowerment and frustration among stakeholders but can potentially negatively impact on individual and community health and well-being. Health impact assessments that effectively assess planning and engagement processes can play a role in mitigating these impacts.
