What are the advantages of ecological?

What is the main advantage of an ecological study?

Ecological studies are particularly useful for generating hypotheses since they can use existing data sets and rapidly test the hypothesis. The advantages of the ecological studies include the large number of people that can be included in the study and the large number of risk-modifying factors that can be examined.

What are the advantages and disadvantages of ecological study?

Ecological studies are therefore usually cheap and easy to perform. However, data are unlikely to be collected for all members of the group of people—the unit of analysis. Thus, when the data are aggregated across the unit of analysis in an ecological study, the outcome measures are likely to be inadequate or biased.

What are the advantages of ecological model of health?

The model allows for there to be integration between behavioral and environmental change. It allows for attention to be given to the interaction between personal and environmental factors. The model also can assist those in need with education of how different factors can play a role in their overall health.

What are the advantages of descriptive epidemiology?

Descriptive epidemiology provides a way of organizing and analyzing data on health and disease in order to understand variations in disease frequency geographically and over time and how disease varies among people based on a host of personal characteristics (person, place, and time).

What is ecology epidemiology?

Definition. Ecological epidemiology is the study of the ecology of infectious diseases. It includes population and community level studies of the interactions between hosts and their pathogens and parasites, and covers diseases of both humans and wildlife.

What are the advantages of case control studies?

Advantages: They are efficient for rare diseases or diseases with a long latency period between exposure and disease manifestation. They are less costly and less time-consuming; they are advantageous when exposure data is expensive or hard to obtain.
