"Epidemiology is the study and analysis of the distribution (who, when, and where), patterns, and determinants of health and disease conditions in a defined population."
Overview of epidemiology, history, and key concepts.
Basic epidemiology concepts: This includes an overview of the field of epidemiology, key terms and definitions, and various types of study designs used in epidemiology studies.
Disease distribution: This involves understanding the patterns of how a disease is spread and how it affects different populations.
Measures of disease frequency: This includes the use of measures such as incidence, prevalence, and mortality rates to understand the occurrence and impact of a disease within a population.
Study designs: This involves understanding the strengths and limitations of different study designs, such as randomized controlled trials, cohort studies, case-control studies, and cross-sectional studies.
Bias: This relates to factors that can influence the accuracy of epidemiological studies, such as selection bias, information bias, and confounding.
Sampling: This includes understanding the different methods used to select participants for epidemiology studies, such as random sampling and cluster sampling.
Data collection and analysis: This involves understanding the methods used to collect and analyze data in epidemiology studies, including survey methods, laboratory methods, and statistical analysis.
Public health surveillance: This includes understanding the use of surveillance systems to monitor disease trends and outbreaks, and the importance of disease reporting and notification.
Outbreak investigation: This involves understanding the principles and methods used to investigate disease outbreaks, including outbreak detection, investigation, and control.
Ethics and epidemiology: This includes understanding ethical principles and considerations in epidemiology research, such as informed consent, privacy, and confidentiality.
Basic Introduction to Epidemiology: This type of introduction provides a general overview of the foundations, principles, and concepts of epidemiology.
Biostatistics and Epidemiology: This type of introduction combines the principles of biostatistics with the methods and applications of epidemiology.
Clinical Epidemiology: This type of introduction focuses on the applications of epidemiology in clinical settings, such as assessing the effectiveness of treatments and interventions.
Environmental Epidemiology: This type of introduction explores the impact of environmental factors, such as pollution and climate change, on human health.
Genetic Epidemiology: This type of introduction focuses on the study of genetic and hereditary factors in diseases and conditions.
Global Health Epidemiology: This type of introduction examines the distribution, determinants, and prevention of diseases and conditions on a global scale.
Infectious Disease Epidemiology: This type of introduction explores the patterns and spread of infectious diseases, such as HIV/AIDS and Ebola.
Nutritional Epidemiology: This type of introduction researches the relationship between nutrition and health outcomes, including obesity, diabetes, and heart disease.
Occupational Epidemiology: This type of introduction investigates the impact of occupational exposures, such as chemicals and physical hazards, on health outcomes.
Pharmacoepidemiology: This type of introduction examines the effects of medications and drugs on health outcomes.
Social Epidemiology: This type of introduction explores the social determinants of health and how they impact disease distribution and outcomes.
Veterinary Epidemiology: This type of introduction examines the health and disease patterns in animal populations, often with an emphasis on zoonotic diseases that can affect humans.
Epidemiology of Aging: This type of introduction studies the impact of aging on health outcomes and the development of age-related diseases.
Health Disparities Epidemiology: This type of introduction investigates the unequal distribution of health outcomes across different populations and how social, economic, and cultural factors contribute to these disparities.
Epidemiology of Violence and Injury: This type of introduction examines the patterns and causes of violence and injury, including accidents, homicide, and suicide.
"It is a cornerstone of public health and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare."
"Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review)."
"Epidemiologists rely on other scientific disciplines like biology to better understand disease processes, statistics to make efficient use of the data and draw appropriate conclusions, social sciences to better understand proximate and distal causes, and engineering for exposure assessment."
"Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials."
"The term epidemiology is derived from Greek, 'epi' meaning 'upon, among', 'demos' meaning 'people, district', and 'logos' meaning 'study, word, discourse,' suggesting that it applies only to human populations."
"The term epidemiology is widely used in studies of zoological populations (veterinary epidemiology), although the term "epizoology" is available, and it has also been applied to studies of plant populations (botanical or plant disease epidemiology)."
"The term 'epidemiology' appears to have first been used to describe the study of epidemics in 1802 by the Spanish physician Joaquín de Villalba in Epidemiología Española."
"The distinction between 'epidemic' and 'endemic' was first drawn by Hippocrates, to distinguish between diseases that are 'visited upon' a population (epidemic) from those that 'reside within' a population (endemic)."
"Epidemiologists also study the interaction of diseases in a population, a condition known as a syndemic."
"The term epidemiology is now widely applied to cover the description and causation of not only epidemic, infectious disease, but of disease in general, including related conditions."
"Some examples of topics examined through epidemiology include high blood pressure, mental illness, and obesity."
"Epidemiology aims to study the distribution, patterns, and determinants of health and disease conditions in a defined population."
"Epidemiology shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare."
"Statistics helps epidemiologists make efficient use of the data and draw appropriate conclusions."
"Epidemiology has helped develop methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences."
"Major areas of epidemiological study include disease causation, transmission, outbreak investigation, and disease surveillance."
"Epidemiology includes environmental epidemiology, which helps in understanding the impact of the environment on disease patterns."
"Epidemiology includes occupational epidemiology, which focuses on studying health issues related to occupations and workplaces."
"Epidemiologists rely on other scientific disciplines like biology to better understand disease processes."
