What are the limitations of epidemiology?

Problems of accuracy of diagnosis or causes of death on death certificates, estimates of population, migration from areas of study, and the issue of “ecological fallacy” are discussed. Retrospective studies have such problems as recall of previous environmental exposure, selection bias and survivor bias.

Why are epidemiological measures useful?

The essence of epidemiology is to measure disease occurrence and make comparisons between population groups. The current section introduces the commonly used measures that help our understanding of the distribution of disease in a given population.

What is the role of epidemiology?

It is the scientific method of investigation problem-solving used by disease detectives— epidemiologists, laboratory scientists, statisticians, physicians and other health care providers, and public health professionals—to get to the root of health problems and outbreaks in a community.

Epidemiology. the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems; the basic science for public health.

What are the three epidemiological measures of disease frequency?

By convention, all three measures of disease frequency (prevalence, cumulative incidence, and incidence rate) are expressed as some multiple of 10 in order to facilitate comparisons. Consider these three examples: Cumulative incidence: 4/10 over 6 years = 0.40 = 40 per 100 or 40% over 6 years.

What is epidemiology mean?

By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).

What are the 5 W’s of epidemiology?
