Learning Objectives:
Upon completion of this lesson, you will be able to:
- Define and discuss risk factors
- Discuss the theories causation relevant to epidemiology
- Relate the epidemiological triad model of infectious disease transmission to public health issues and interventions
- Explain the difference between association and causation
- Discuss the causal criteria that can be used to establish causation

-
Scroll down to "Chapter 2: Measuring health and Disease" and read page 32 titled "Health determinants, indicators, and risk factors."
-
Scroll down to "Chapter 5: Causation in epidemiology" and read pages 83 to 97. Learn more about causation in epidemiology. Answer 'Study questions' 5.1, 5.2, 5.4, and 5.3 on pages 96 and 97. Be sure to check your answers on pages 195-196.
-
Scroll down to "Lesson One: Introduction to Epidemiology" and read the section titled "Concepts of Disease Occurence" (pages 1-52 to 1-55), and complete 'Exercise' 1.8 on page 1-56.
-
Read the web page to learn the difference between association and causation.
-
Read the article and and reflect on the causal criteria that can be used to establish causation.
-
Read the article titled "Theories for Social Epidemiology in the 21st Century" and reflect on the social production of health and inequity.
-
In "Closing the Gap in a Generation" read the "Executive Summary" on pages 1 to 23. Pay special attention to the different social determinants of health the Commission addresses.

This activity discusses the Social Determinants of Health (SDH) and how they contribute to the inequitable distribution of disease risk.
Step 1: The three “Principles of Action” outlined in the final report to the Commission on Social Determinants of Health are essential to achieving health equity. These actions contain a host of SDH such as access to decent employment, and gender equity. This resource was assigned as an Essential Resource in Module 3 and the link can also be found there. Read the "Executive Summary" (pages 1-23), paying special attention to the different social determinants of health the Commission addresses.
Step 2: Find one recent news article (published within the past month), in a newspaper or on a news website, that features a health issue in your particular country or community. Alternatively, you can find one new story of interest on CDC Global Health in the News. (Choose one story from the list of news stories).
Step 3: Write an 800 to 1200 word essay that includes the following information and answers to the following questions:- Briefly summarize the main features of the health issue you selected, and how it is affecting the country or community where it exists.
- What are the main risk factors for this health issue?
- Outline three social determinants of health that could influence those who are most at risk for this health issue. Describe how these social determinants are linked and relevant to this health issue. (Note: it may help to go through the determinants described by the Commission and try to visualize how each may be linked to the health issue you selected. For example, how might income, employment, gender, structural racism, global warming, physical environments, access to health services, etc. influence those who are at risk?)
- Briefly describe 3 actions you recommend that could improve health equity related to this health issue. (These recommendations can be community actions, government actions, or international actions but they must address all three of the social determinants you described in question 3).
Have I successfully identified the main risk factors for the selected health issues?
- Have I clearly described the relevance of social determinants to the selected health issue?
- Have I proposed three actionable recommendations aimed at improving health equity in relation to the identified social determinants?
Use this evaluation to critically assess the completeness and depth of your analysis. Once you are confident that your work is comprehensive and aligns with the specified criteria, submit your revised document to the appropriate section of the course platform for final review.
Step 5: Submit your assignment by clicking “add a new discussion topic” below and completing the fields.
OPTIONAL Step 6: Interact (10 minutes)
If you would like to, you can reply to your peers' posts in a respectful and professional manner. Ensure that your post engages your peers' ideas by including a reflection on their comments, sharing ideas of other potential difficulties and parties involved, or asking thought-provoking questions. If a peer comments on your posting, please reply. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “Post to forum.”
- Briefly summarize the main features of the health issue you selected, and how it is affecting the country or community where it exists.

Smoking is widely accepted to be a cause of lung cancer. However, 95% of heavy smokers never develop lung cancer. How can this apparent contradiction be explained?
