Abstract

Overview

The study examines the diverse health responses of residents exposed to the environmental health risk posed by a new high-voltage power line. It utilizes a quasi-experimental prospective field study design with assessments before and after the power line's operation.

Findings

• A significant number of residents (229 individuals in proximity within 0-300 meters) participated, reporting their health status and environmental perceptions.
• Through latent class growth models, residents were categorized into distinct classes based on their reactions to the power line—with a notable 49% exhibiting stable emotional and health responses, while 9% showed heightened sensitivity and health concerns post-activation.
• Variations in responses correlate strongly with pre-existing knowledge of power line health effects, awareness of the activation, and subsequent health perceptions.

Conclusion

This typology underlines the importance of understanding public perceptions and health responses to address and manage potential risks effectively when introducing new high-voltage power infrastructures.
