With improvements in survival to adulthood, improved economic and political states, and development of global markets of food and products has come changes to human behavior, exposure, and risks. As morbidity and mortality from communicable diseases has fallen, death from cardiovascular diseases and cancer have become the most common causes of death of adults in every region. And in areas with developing infrastructure and variable safety and quality controls, accidents and injuries remain an important cause of disability and death around the world across the adolescent and adult ranges. Lastly, mental health is a growing concern around the world, with significant disability burden from depression, anxiety, and substance-use disorders that has had little attention until recent years in terms of prioritization for funding and policy.

For most of these non-communicable diseases, there are important behavioral changes that can prevent disease/premature death (as if behavioral change was an easy thing to accomplish for patients!). All of them require access to healthcare services that include early diagnosis and access to treatment, which could mean regular access to long-term medication for disease control (such as hypertension), access to expensive medication (like chemotherapy), or access to trained surgeons (for example, trauma) and the ancillary services required for surgery (such as anesthesia, OR, sterile equipment, etc). As you can imagine, there are many complex barriers to strengthening health systems around the world toward these goals.

While these are grouped into “non-communicable diseases,” there are multiple distinct topics. For this module, there are three areas of focus:

    1. Diseases with modifiable risk factors (primarily cardiovascular and chronic respiratory disease)
    2. Mental health and disorders
    3. Global surgery.

Learning objectives

Non-communicable diseases and modifiable risk factors

(Choose one topic.)

On the Slack discussion board:

  • For country of interest:
    To explore these topics, in addition to the data sources you have encountered so far, consider using social media, news outlets, or other content that persons in that country may be likely to interact with.
    1. What is the diet like—how does it differ between the affluent vs impoverished in the area?
    2. How much of the diet is high in trans fat, sodium, or highly-processed products?
    3. Select one of the major NCDs (Cardiac disease, Diabetes, Cancer) and explore the state of diagnosis, access to care and medications, screening, or prevention efforts.
    4.  Is there evidence of policies aimed at improving burden of disease around NCDs? Is it a "package" of evidence-based interventions and what sectors are represented in the interventions (as described in Dr. Angell's presentation/Yale Grand Rounds)?
    5. What messages or norms are in the community around food, tobacco, or EtOH?
    6. What terms are used in this community for cardiac disease, hypertension, diabetes? Are there idioms used in the language that might be new to you?

Non-communicable diseases: Mental health

(Choose one discussion topic.)

On the Slack discussion board:

  • Consider the World Happiness Report and Happiness Index and share your thoughts:
    • How might you explain the different indices between high-income countries and low-income countries?

    • How might you explain difference within income designations?

    • What are relevant factors in a population that contribute to happiness? How many of those factors would be relevant to mental health disorders; how might those factors affect a persons' experience with mental health or a health systems' approach to diagnosis and treatment of mental health disorders?

  • For country of interest, explore social media, news outlets, and other available material. How is mental health discussed, portrayed, and/or being addressed?

Podcast: The Global Cause of Mental Health 

  • This podcast interviews two experts who have devoted their lives to global mental health. Vikram Patel, MD, is a professor of global health at the Harvard University Chan School of Public Health (same as the above TED talks and two cited articles). In April 2015, he was listed as one of the world’s 100 most influential people by TIME magazine. Fran Silvestri has been the director of the International Institute of Mental Health Leadership since the organization’s inception 20 years ago.

Explore the World Happiness Report and Happiness Index. While the measure of 'happiness' is not equivalent to the absence of mental disorders/disease, it is useful to think about how this study on the happiness index differs around the world: How do we explain the differences?

Non-communicable diseases: Global surgery

On the Slack discussion board:

  1. Choose one discussion topic for country of interest:

    • What are surgical services like?
    • How many surgeons are there?
    • How many anesthesiologists?
    • Are there surgical training programs in-country or are surgeons trained elsewhere?
    • Are there NGOs or Global health programs from high-income countries?
      • What is the scope of the work done?
      • What sources fund the work?
      • What are relationships between the organization and local leadership?
      • Are outcomes measured and reported—how and to whom?
