Epidemiology in general
Fichas del conjunto (9)
- 1EpidemiologyThe study of the distribution of disease in populations, and the factors that contribute to this distribution. This is done through comparisons between groups, where patterns such as correlation can be discovered. Quantitative.
- 2Applications of epidemiologyDescribe the health and unhealth in a population
Identify risk factors for disease
Studies of disease history or studies aiming to make prognosis for future disease
Evaluate public health measures
Provide data as foundation for public policy - 3Quantitative concepts relevant for epidemiologyMeasures of frequency
Measures of association
Statistical inference - 4Measures of frequencyCounts and rates (how many)
- 5Measures of associationIncidence rate ratios
Relative risks
Odds ratios
Standardised mortality/morbidity rates - 6Two very relevant concepts in statistical inferencesP-value (the likelihood of an association to be random and not due to an actual difference. By tradition p <0.05 is considered significant)
Confidence interval (the probability that a new study would have findings within the interval, by tradition 95% is often used, ie 95% probability that the true value is within the interval) - 7Historical development of epidemiologyJohn Snow mapped out cholera outbreaks and wells in London, discovering that getting water from certain wells was related to disease. By closing wells, the outbreak decreased. The mechanism does not need to be known for observational data to be useful.
- 8Current epidemiologyComputational power, Big Data, new statistical software and increasing access to data gives new opportunities and challeges to the field. Genetic epidemiology evolves as genomwide association studies become possible. There are many subcategories under the umbrella of epidemiology.
- 9Two main categories of epidemiological studiesDescriptive (what is the occurence of disease)
Analytical (what is the etiology, cause, of disease)
