Incidence: The number of new cases of a disease that develop in a specified population during a specific time period. It measures the risk of developing the disease.
Formula:
[
\text{Incidence Rate} = \frac{\text{New Cases}}{\text{Population at Risk}} \times 1000
]
Prevalence: The total number of existing cases (new and pre-existing) of a disease in a population at a specific point in time. It reflects disease burden.
Formula:
[
\text{Prevalence} = \frac{\text{Total Cases}}{\text{Total Population}} \times 100
]
Risk Factor: An attribute, characteristic, or exposure that increases the likelihood of developing a disease. It can be behavioral, environmental, or genetic.
Epidemiological Study Design: A systematic approach to investigate health-related states, including descriptive (e.g., cross-sectional) and analytical (e.g., cohort, case-control, RCT) studies.
Measures of Association: Quantitative tools (e.g., Risk Ratio, Odds Ratio) used to assess the strength of the relationship between exposure and disease.
