What Classes Do Public Health Majors Take?

Public health is an interdisciplinary field that aims to improve the health and well-being of communities and populations. As such, public health majors take a variety of courses that cover topics ranging from epidemiology to environmental health, from global health to public health ethics and law. In this article, we will explore some of the classes that public health majors typically take in their academic journey.

Introduction to Public Health

One of the first classes that public health majors take is an introduction to public health. This course is designed to provide students with a broad overview of the field of public health, including its history, key concepts, and major challenges. Students learn about the different disciplines that contribute to public health, such as epidemiology, biostatistics, environmental health, and health policy and management. They also explore the various determinants of health, such as social, economic, and environmental factors.

Biostatistics

Biostatistics is another essential class for public health majors. This course teaches students how to use statistical methods to analyze and interpret health data. Students learn how to calculate measures of central tendency and dispersion, how to conduct hypothesis tests and confidence intervals, and how to use regression analysis to model relationships between variables. Biostatistics is critical for designing and evaluating public health interventions and for conducting research in the field.

Epidemiology

Epidemiology is the study of the distribution and determinants of health and disease in populations. It is a foundational course for public health majors, as it provides them with the skills and knowledge to understand and control the spread of diseases. Students learn about the different types of epidemiological studies, such as cross-sectional, case-control, and cohort studies. They also learn about the measures of disease frequency and association, such as incidence and prevalence rates and relative risks. Epidemiology is essential for designing and implementing public health interventions to prevent and control communicable and non-communicable diseases.

Environmental Health

Environmental health is the study of how environmental factors affect human health. This course teaches students about the different types of environmental hazards, such as air pollution, water contamination, and hazardous waste. Students learn about the sources, pathways, and effects of these hazards on human health. They also learn about the strategies for preventing and controlling environmental hazards, such as risk assessment, regulation, and community-based approaches. Environmental health is a critical component of public health, as it addresses one of the major determinants of health.

Global Health

Global health is the study of health issues that transcend national boundaries and affect populations worldwide. This course provides students with an understanding of the global burden of disease, the major causes of morbidity and mortality, and the disparities in health outcomes between developed and developing countries. Students learn about the different approaches to addressing global health challenges, such as the Millennium Development Goals and the Sustainable Development Goals. They also learn about the key players in global health, such as the World Health Organization and the Gates Foundation. Global health is critical for public health majors, as it prepares them to work in a globalized world and to address global health challenges.

Behavioral and Social Sciences in Public Health

Behavioral and social sciences are critical components of public health, as they address the human behaviors and social contexts that influence health outcomes. This course teaches students about the different theories and models of health behavior, such as the Health Belief Model and the Social Ecological Model. They also learn about the different strategies for promoting healthy behaviors and reducing health disparities, such as social marketing and community-based participatory research. Behavioral and social sciences are essential for designing and implementing effective public health interventions that address the root causes of poor health.

Health Policy and Management

Health policy and management is the study of how healthcare systems are organized, financed, and delivered. This course provides students with an understanding of the different types of healthcare systems, such as single-payer and multi-payer systems, and the different models of healthcare delivery, such as fee-for-service and capitation. Students also learn about the different stakeholders in healthcare, such as patients, providers, insurers, and policymakers. Health policy and management is critical for public health majors, as it prepares them to work in healthcare organizations and to advocate for policies that improve health outcomes.

Public Health Research Methods

Public health research methods are the tools and techniques used to conduct research in the field of public health. This course teaches students about the different types of research designs, such as experimental and observational studies, and the different data collection methods, such as surveys and interviews. Students also learn about the different ethical and legal issues involved in conducting public health research, such as informed consent and confidentiality. Public health research methods are essential for conducting rigorous and ethical research in public health.

Communicable and Non-Communicable Diseases

Communicable and non-communicable diseases are two major categories of diseases that affect populations worldwide. This course teaches students about the different types of communicable and non-communicable diseases, their causes, symptoms, and treatments. Students also learn about the different strategies for preventing and controlling these diseases, such as vaccination and lifestyle interventions. Communicable and non-communicable diseases are critical topics for public health majors, as they represent major challenges to global health.

Public Health Ethics and Law

Public health ethics and law are the principles and rules that guide the practice of public health. This course teaches students about the different ethical and legal issues involved in public health, such as human subjects protection, health disparities, and access to care. Students also learn about the different frameworks for ethical decision-making, such as utilitarianism and deontology. Public health ethics and law are critical for public health majors, as they prepare them to work in complex and dynamic ethical and legal environments.

Conclusion

Public health majors take a variety of courses that cover a broad range of topics, from epidemiology to environmental health, from global health to public health ethics and law. These classes provide students with the skills and knowledge they need to address the major challenges facing populations worldwide, such as communicable and non-communicable diseases, health disparities, and environmental hazards. Public health is an interdisciplinary field that requires a holistic and collaborative approach to improving health outcomes. By taking these courses, public health majors are prepared to work in a variety of public health settings, including governmental agencies, non-profit organizations, and healthcare systems.
