Recall bias is of particular concern in retrospective studies that use a case-control design to investigate the etiology of a disease or psychiatric condition. [ 3 ] [ 4 ] [ 5 ] For example, in studies of risk factors for breast cancer , women who have had the disease may search their memories more thoroughly than members of the unaffected ...
Although in classical case–control studies, it remains true that the odds ratio can only approximate the relative risk in the case of rare diseases, there is a number of other types of studies (case–cohort, nested case–control, cohort studies) in which it was later shown that the odds ratio of exposure can be used to estimate the relative ...

Low SES (socioeconomic status) is an important determinant to quality and access of health care because people with lower incomes are more likely to be uninsured, have poorer quality of health care, and or seek health care less often, resulting in unconscious biases throughout the medical field.

For example, recall bias is likely to occur in cross-sectional or case-control studies where subjects are asked to recall exposure to risk factors. Subjects with the relevant condition (e.g. breast cancer) may be more likely to recall the relevant exposures that they had undergone (e.g. hormone replacement therapy) than subjects who don't have ...
There are various types of epidemiological studies in use: case-control studies, cohort studies, experimental controlled randomised trials (RCTs). Experimentation, in general, is a general scientific method of testing causal hypotheses by means of an intervention (controlled influence) in the natural course of the phenomenon under study.
Both the relative risk and odds ratio are relevant in retrospective cohort studies, but only the odds ratio can be used in case-control studies. Although most case-control studies are retrospective, they can also be prospective when the researcher still enrolls participants based on the occurrence of a disease as new cases occur.

Tobacco use, alcoholism, multiple sex partners, substance use, reckless driving, obesity, or unprotected sexual intercourse are some examples. Human beings have, in principle, control over their conduct. Behavior modification can contribute to the success of self-control, and health-enhancing behaviors. Risky behaviors can be eliminated ...
