Ecologic Study
The study of risk changing aspects on health, or other results of the population based on geographic or temporary description, is known as ecological studies. Almost all of the epidemiological studies of etiology are observational. They want to inquire, the relation between the transpiration of disease and exposure, to identified or assumed factors. The main component of observation is population or society in ecological studies. Researchers usually measures, the association between disease rate and exposure through each series of population. Mostly the data are collected from the available statistic reports and hence, it does not take time to collect data exclusively. In this study, researchers measures the one variable either disease rate or exposure from the level of group. For example, occurrence rate of cancer in one particular society, the mean level of blood pressure of the patients in hospital, or the average daylight at different places (T.KO, 2008).
