• Prevention and health promotion are prioritized over treatment.
• The goal is to create environments where healthy choices are the easiest to make.

Population-Based Focus

• It focuses on the health of entire communities.
• Vaccination campaigns and sanitation systems are examples of initiatives taken.
• The ultimate aim is to reduce health disparities and improve overall health outcomes within the population.

Key Principles of Public Health

• Prevention aims to stop diseases and health issues before they start.
• Health promotion encourages behaviors that lead to better health.
• Health equity ensures everyone has access to the resources needed for good health.

Importance of Prevention

• Risk reduction involves finding and reducing risk factors for diseases common in populations.
• Examples of prevention include vaccination programs and smoking cessation initiatives.

• Regular tracking of progress and making necessary adjustments are part of monitoring.
• Rolling out a vaccination campaign in schools is an example of putting plans into action.

Evaluation of Effectiveness

• Measurement of success includes surveys, health outcomes data, and feedback.
• There should be continuous improvement using evaluation results to refine programs.
• An example includes assessing the impact of a nutrition initiative on obesity rates.

Example: Tobacco Control in Saudi Arabia

• Public education, smoking bans, and taxation are strategies used.
• Reduced smoking rates and improved public health are outcomes.
