An ecological study is an observational study defined by the level at which data are analysed, namely at the population or group level, rather than individual level. Ecological studies are often used to measure prevalence and incidence of disease, particularly when disease is rare.
Is ecological study descriptive?
Ecological studies can either be descriptive, for example, exploring variation between populations, or consider associations such as the example above.
Why is ecological study important?
Why is ecology important? Ecology enriches our world and is crucial for human wellbeing and prosperity. It provides new knowledge of the interdependence between people and nature that is vital for food production, maintaining clean air and water, and sustaining biodiversity in a changing climate.
What is outcomes research and ecological studies?
Ecological studies are conducted by researchers in a variety of disciplines, including outcomes researchers, to study potential causal associations between 1 or more exposure and outcome variables.
Is ecological study a cohort study?
Relative risk is the measure of effect for a cohort study. Cohort studies are subject to very low recall bias, and multiple outcomes can be studied simultaneously. … Therefore, ecological study results are applicable only at the population level.
What is an example of a ecological study?
Examples of the use of ecological studies include: Correlating population disease rates with factors of interest, such as healthcare use. Demonstrating changes in mortality over time (time series) Comparing the prevalence of a disease between different regions at a single point in time (geographical studies)
What are epidemiological studies?
What is Epidemiology? … Epidemiologic studies are the foundation for disease control and prevention through tracking the prevalence of the disease, characterizing the natural history, and identifying determinants or causes of the disease. . It defines risk factors for a disease and targets for preventive medicine.
When should you do an ecological study?
Ecological studies are often used to measure prevalence and incidence of disease, particularly when disease is rare. … Also, because they are area-level studies, care must be taken when extrapolating either to individuals within the area level of measurement, or to a higher population level.

What is an ecological concept?
Ecological concepts are general understandings (or facts) about ecosystems and ecosystem management. Ecological principles are basic assumptions (or beliefs) about ecosystems and how they function that are informed by the ecological concepts.
What is epidemiology study design?
The basic epidemiological study designs are cross-sectional, case-control, and cohort studies. … Cohort studies identify the study groups based on the exposure and, then, the researchers follow up study participants to measure outcomes.
What is ecologic study design?
Ecologic studies are studies in which the unit of observation is a group, not separate individuals, for one or more study variables. For example, exposure and risk factors are known only at the group level, such as the average air pollution concentration in different cities.
What is ecological data?
Ecological science involves integrating, analyzing, visualizing and collecting better information about plants, animals, microbes of different ecosystems, observing how they interact among themselves and the environments where they are co-located in nature. …
What is the difference between an ecological study and a cross-sectional study?
Ecological Study – A study in which at least one variable, either an exposure or the outcome, is measured at the group (not individual) level. … Cross-Sectional Study – A study with individual-level variables that measures exposure and disease at one point in time. A snapshot of the study population.
What is an ecological study vs cross-sectional?
An ecological study is one where you take values of a variable for an entire population, the outcome from that population, and use that to draw inference. A cross-sectional study is where you look at individuals within a population at a single point in time.
What is correlational study in epidemiology?
Correlational studies, also called ecological studies, use grouped population data to relate exposure patterns of whole populations to disease incidence or mortality rates for whole populations.
