Global Health and Epidemiology
Research Guide
What is Global Health and Epidemiology?
Global Health and Epidemiology is the study of healthcare patterns, disease burdens, and public health challenges across populations worldwide, encompassing topics such as medical admissions, non-communicable diseases, healthcare policies, cardiovascular diseases, public health, epidemiological profiles, geriatric patients, rural healthcare, and globalization's impact on healthcare systems.
This field includes 24,653 works analyzing patterns in healthcare delivery and disease prevalence globally. Key areas cover non-communicable diseases, cardiovascular conditions, and public health interventions in low- and middle-income countries. Research draws from systematic analyses like those in the Global Burden of Disease studies.
Topic Hierarchy
Research Sub-Topics
Global Burden of Disease
Global Burden of Disease studies quantify disability-adjusted life years (DALYs), years of life lost (YLLs), and healthy life expectancy across populations. Researchers develop metrics, model trends, and analyze risk factors using GBD frameworks.
Non-Communicable Disease Epidemiology
Non-communicable disease epidemiology tracks cardiovascular, cancer, diabetes, and respiratory disease patterns in low- and middle-income countries. Researchers investigate transitions, risk attribution, and prevention strategies via cohort studies.
Infectious Disease Burden Estimation
Infectious disease burden estimation measures incidence, mortality, and economic impact of tuberculosis, malaria, and neglected tropical diseases. Researchers use surveillance data, modeling, and serological surveys for underreported regions.
Epidemiological Transitions
Epidemiological transitions analyze shifts from infectious to chronic disease dominance across regions and socioeconomic gradients. Researchers model stage variations, demographic drivers, and health system responses.
Environmental Risk Factors in Epidemiology
Environmental risk factors in epidemiology quantify impacts of water, sanitation, air pollution, and climate on disease burdens. Researchers apply exposure-response modeling and attribution methods to inform interventions.
Why It Matters
Global Health and Epidemiology quantifies disease burdens to guide policy and resource allocation, such as revealing that countries with intensive malaria had 1995 income levels of only 33% that of countries without malaria, controlling for factors like tropical location and colonial history (Gallup and Sachs, 2001, "The economic burden of malaria"). In low- and middle-income countries, the growing epidemic of coronary heart disease underscores needs for prevention strategies (Gaziano et al., 2009, "Growing Epidemic of Coronary Heart Disease in Low- and Middle-Income Countries"). Analyses like the burden from inadequate water, sanitation, and hygiene highlight targeted interventions in vulnerable regions (Prüss‐Üstün et al., 2019, "Burden of disease from inadequate water, sanitation and hygiene for selected adverse health outcomes: An updated analysis with a focus on low- and middle-income countries"). These insights support efforts against tuberculosis, child mortality, and non-communicable diseases in sub-Saharan Africa (Gouda et al., 2019, "Burden of non-communicable diseases in sub-Saharan Africa, 1990–2017: results from the Global Burden of Disease Study 2017").
Reading Guide
Where to Start
"GBD 2010: design, definitions, and metrics" by Murray et al. (2012) provides foundational methods for understanding disease burden metrics, making it the ideal starting point for grasping core concepts in global health epidemiology.
Key Papers Explained
Murray et al. (2012, "GBD 2010: design, definitions, and metrics") establishes the methodological framework that Liu et al. (2012, "Global, regional, and national causes of child mortality: an updated systematic analysis for 2010 with time trends since 2000") and Dandona et al. (2017, "Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study") apply to specific mortality and transition analyses. Hotez et al. (2014, "The Global Burden of Disease Study 2010: Interpretation and Implications for the Neglected Tropical Diseases") interprets these metrics for neglected diseases, while Gouda et al. (2019, "Burden of non-communicable diseases in sub-Saharan Africa, 1990–2017: results from the Global Burden of Disease Study 2017") extends the approach to regional non-communicable disease trends.

Advanced Directions
Recent works build on Global Burden of Disease frameworks to track non-communicable diseases in sub-Saharan Africa through 2017 (Gouda et al., 2019) and water-sanitation-hygiene burdens in low- and middle-income countries (Prüss‐Üstün et al., 2019). Focus shifts to subnational variations and economic linkages like malaria's poverty effects.

Frequently Asked Questions
What are the leading causes of child mortality globally?
Li Liu et al. (2012) conducted an updated systematic analysis for 2010 with time trends since 2000, identifying key causes through global, regional, and national data ("Global, regional, and national causes of child mortality: an updated systematic analysis for 2010 with time trends since 2000"). This work provides metrics on preventable deaths to inform public health priorities.
How does malaria impact economic development?
Gallup and Sachs (2001) showed that countries with intensive malaria had 1995 income levels of only 33% that of countries without malaria, after controlling for tropical location, colonial history, and geographical isolation ("The economic burden of malaria"). This connection highlights malaria's role in perpetuating poverty.
What is the design of the Global Burden of Disease Study 2010?
Murray et al. (2012) outlined the GBD 2010's design, definitions, and metrics, establishing standardized methods for measuring disease burdens across populations ("GBD 2010: design, definitions, and metrics"). These frameworks enable comparable health outcome assessments worldwide.
What is the burden of non-communicable diseases in sub-Saharan Africa?
Gouda et al. (2019) reported results from the Global Burden of Disease Study 2017, detailing non-communicable disease trends from 1990 to 2017 in sub-Saharan Africa ("Burden of non-communicable diseases in sub-Saharan Africa, 1990–2017: results from the Global Burden of Disease Study 2017"). The analysis quantifies rising prevalence and implications for health systems.
How does epidemiological transition vary across Indian states?
Dandona et al. (2017) analyzed variations in India's epidemiological transition from 1990 to 2016 using Global Burden of Disease data, showing state-level differences in disease patterns ("Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study"). This reveals heterogeneous public health needs within countries.
