"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."
The study of the patterns and causes of diseases in populations.
Introduction to Epidemiology: Overview of epidemiology, history, and key concepts.
Measures of Disease Frequency: Methods to measure the frequency of diseases in a population.
Study Designs in Epidemiology: Types of study designs used in epidemiological research, including cross-sectional, case-control, cohort, and clinical trials.
Bias and Confounding: Sources of error in epidemiological research and methods to control them.
Sampling Methods and Study Size: Ways to select study participants and calculate the appropriate sample size.
Data Collection and Management: Methods to collect and manage data in epidemiological research.
Descriptive Epidemiology: Methods to describe the distribution of disease in a population.
Diagnostic Tests: Evaluation of tests used to diagnose diseases in a population.
Measures of Association: Methods to measure the strength of the association between risk factors and diseases.
Interpretation and Presentation of Epidemiological Data: Interpreting and presenting epidemiological data to various audiences.
Infectious Disease Epidemiology: Concepts and methods used in the study of infectious diseases.
Chronic Disease Epidemiology: Concepts and methods used in the study of chronic diseases.
Environmental Epidemiology: Concepts and methods used in the study of environmental exposures and their impact on health.
Molecular and Genetic Epidemiology: Concepts and methods used in the study of molecular and genetic factors in disease.
Social Epidemiology: Concepts and methods used in the study of social factors in health and disease.
Global Health Epidemiology: Concepts and methods used in the study of health disparities and health equity globally.
Emerging and Reemerging Infectious Diseases: Exploration of new and resurging infectious diseases, and methods to control outbreaks.
Public Health Practice and Policy: Application of epidemiological knowledge to public health practice and policy making.
"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."
