  6. Chronic Disease: Prevention • CDC estimates that 70% of deaths in the US are now caused by chronic diseases • Public health focus on behaviour modification • Chronic diseases mainly due to four modifiable health risk behaviors • lack of physical activity • poor nutrition • tobacco use • excessive alcohol consumption Introduction to Healthcare and Public Health in the US Public Health (Part 2) Lecture c

  7. Chronic Disease: Education • Since behavior modification is the main public health goal, the tools to effect that are – • Education and informational materials • For the public • For health care practitioners • For policymakers • Funding opportunities • Recommendations, best practices, guidelines Introduction to Healthcare and Public Health in the US Public Health (Part 2) Lecture c

  8. World Health Organization (WHO) and Chronic Diseases • The WHO has developed the “Stepwise Framework” • PLANNING • STEP 1: Estimate population need and advocate for action • STEP 2: Formulate and adopt policy • STEP 3: Identify policy implementation steps • IMPLEMENTATION • Table of 3 steps Introduction to Healthcare and Public Health in the US Public Health (Part 2) Lecture c

  10. Environmental Public Health • Environmental public health is vital to population health • Removal of lead from gasoline and from house paint are two of the numerous triumphs of this field • Other critical functions include air and water quality monitoring and education, and hazardous waste management Introduction to Healthcare and Public Health in the US Public Health (Part 2) Lecture c

  11. Environmental Topics: By Means of Contact • One way of categorizing environmental topics is by their means of contact with the population, such as - • air quality • food protection • radiation protection • solid waste management • hazardous waste management • water quality • noise control • environmental control of recreational areas • housing quality • vector control • Another categorization method is to organize topics by public health program,, as shown on the next slide.

  12. Environmental Topics: By Public Health Programs • Air Quality  • Bioterrorism Agents/Diseases  • Chemical Agents  • Environmental Hazards and Exposure  • Food Safety  • Hazardous Substances  • Hazardous Waste Sites  • Health Disorders and the Environment • Herbicides • Hydrocarbons  • Laboratory Measurements in People  • Lead  • Natural Disasters  • Pesticides  • Smoking and Tobacco Use  • Urban Planning for Healthy Places  • Vessel Sanitation and Health  • Water Quality  Public Health environmental programs and topics include: Introduction to Healthcare and Public Health in the US Public Health (Part 2) Lecture c

  13. Chronic Diseases and Environmental Public Health • There is some overlap between chronic diseases and environmental topics. Some examples – • Smoking, asthma, air quality • Cancer, environmental hazards and exposure, chemical agents • Similarly, there are overlaps between communicable diseases and environmental topics, such as • Bioterrorism • Water quality and water-related diseases • Divisions between different facets of public health can be artificial, created for efficiency of organization. In actuality, relationships between facets of public health are often complex rather than simple, as illustrated in the above examples.
