What are the 3 major types of epidemiologic studies?

Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.

Which is the most powerful epidemiological study?

Randomized, controlled clinical trials are the most powerful designs possible in medical research, but they are often expensive and time-consuming. Well-designed observational studies can provide useful insights on disease causation, even though they do not constitute proof of causes.

What are epidemiological risk factors?

In epidemiology, a risk factor or determinant is a variable associated with an increased risk of disease or infection. Determinant is often used as a synonym, due to a lack of harmonization across disciplines, in its more widely accepted scientific meaning.

Why poor health is the major cause of disease?

Overcrowded and poor living conditions can contribute to the spread of airborne diseases such as tuberculosis and respiratory infections such as pneumonia. Reliance on open fires or traditional stoves can lead to deadly indoor air pollution. A lack of food, clean water and sanitation can also be fatal.

Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).

What is the strongest study design?

A well-designed randomized controlled trial, where feasible, is generally the strongest study design for evaluating an intervention’s effectiveness.

What is epidemiologic evidence?

Unlike laboratory experiments, epidemiology provides evidence based on studies of human populations under real-world conditions. It largely avoids the extrapolations across species and levels of exposure that are required for the use of data from animal experiments, and which contribute large uncertainties.

What are the six risk factors?
