Review Questions

• How does GIS technology enhance public health efforts in communities?
  • GIS technology enhances public health efforts by allowing for spatial analysis of health data. It helps identify trends in disease outbreaks, assess risk factors in specific areas, and allocate resources efficiently. By visualizing data on maps, public health officials can pinpoint vulnerable populations and develop targeted interventions based on geographic needs.
• Discuss the role of health promotion in improving community well-being within public health frameworks.
  • Health promotion plays a critical role within public health frameworks by focusing on empowering individuals and communities to make healthier choices. This includes providing education about nutrition, physical activity, and preventive measures against diseases. Effective health promotion strategies often involve partnerships with local organizations to foster supportive environments that encourage healthy behaviors.
• Evaluate the impact of environmental factors on public health outcomes and how they can be addressed through policy changes.
  • Environmental factors such as pollution, access to clean water, and safe housing significantly impact public health outcomes. Poor air quality can lead to respiratory diseases, while inadequate sanitation can result in outbreaks of infectious diseases. Addressing these issues through policy changes—such as implementing stricter environmental regulations or improving urban planning—can enhance living conditions and reduce health risks for communities, ultimately leading to improved overall public health.
