The role of beliefs and behavioral intentions in the analysis of community health responses to climate change

This study explores the complex relationship between climate change perceptions and health behavior intentions through an extended Health Belief Model (HBM). Given the increasing frequency of climate-related events, such as extreme weather and air quality deterioration, the implications for public health are profound. This study aims to identify how individual beliefs regarding susceptibility to climate-related health issues, perceived severity of these impacts, and the perceived benefits and barriers to action influence health behavior intentions. Data were collected from approximately 500 adults in Iran using an online questionnaire distributed via popular messaging platforms. The survey assessed demographic factors alongside key constructs of the HBM. The findings indicate that individuals who perceive a higher susceptibility and severity regarding climate impacts are more likely to express intentions to engage in health-promoting behaviors. Furthermore, increased environmental concern and social norms significantly enhance these intentions, while perceived barriers and self-efficacy don’t present a notable hindrance. The results underscore the critical need for interdisciplinary public health strategies that integrate climate science and community engagement. By fostering awareness and understanding of climate-related health risks, such strategies can promote proactive health behaviors and enhance community resilience in the face of ongoing climate challenges. This research contributes valuable insights for designing effective public health interventions that resonate with community values and address the multifaceted impacts of climate change on health.
