- Organized, population-wide approaches to disease detection; an examination of a group of usually asymptomatic people to detect those with a high probability of having a given disease; aim is to detect the disease before the usual time of diagnosis. What is case-finding? Opportunistic attempts at early detection when a person comes into contact with the health system for another reason; diagnostic approach used when a person is already suspected of having a disease. What are the levels of prevention? Preventing a disease or disorder before it happens; health promotion, health education, and health protection are examples. What is secondary prevention? Prevention aimed at the health screening and detection activities used to identify disease; aims to block the progression of disease or prevent an injury from developing into an impairment or disability.
- What is tertiary prevention? Prevention whose aim is to retard or block the progression of a disability, condition, or disorder in order to keep it from advancing and requiring excessive care; limiting any disability by providing rehabilitation where disease, injury, or a disorder has already occurred and has caused damage. What are the strategies for prevention? What is the mass strategy for prevention? Better approach for common or widespread problems; aims to reduce health risks of the entire population; immunization programs and fluoridation of water are examples. What is a risk factor? Anything that increases a person's chance of developing a disease behavioral, environmental, genetic, and social What are at-risk behaviors? An activity performed by persons who are healthy, but are at greater risk of developing a particular disease, condition, or disorder because of the behavior. What are predisposing factors? Those existing factors or conditions that produce a susceptibility or disposition in a host to a disease or condition without actually causing it; precede the direct cause.

What is blinding? Used in experimental studies to minimize potential bias from a placebo effect. What are the levels of blinding? Placebo-controlled study where the subjects are blind but investigators are aware of who is receiving the active treatment. What is a double blind study? Neither the subjects nor the investigators know who is receiving the active treatment. What is a triple blind study? Not only are the treatment and research approaches kept a secret for the subjects and investigators, but the analyses are completed in a way that is removed from the investigators. What are the implications related to blinding? In some situations, it may be impossible or unethical to blind; may be problematic to blind in drug studies where a treatment has characteristic side effects; building side effects into a placebo may also be unethical. What are the strengths of blinding? Demonstrate cause-effect relationships; may produce a faster and cheaper answer than observational studies; only appropriate approach for some research questions; allow investigators to control the exposure levels as needed.- What are the weaknesses of blinding? Often more costly in time and money; many research questions are not suitable for experimental designs because of ethical barriers and because of rare outcomes; many research questions are not suitable for blinding; standardized interventions may be different from common practice; may have limited generalizability due to the use of volunteers, eligibility criteria, and loss to follow-up. What are the criteria for establishing causal associations?
- Ans:- B 82 Describe the disadvantages of the case control study A A cohort is different because an entire cohort of exposed individuals is examined. A case study makes use of limited number of cases and controls who usually do not represent an entire cohort of exposed individuals. B the measurement of exposure may be inaccurate. Representativeness of cases and controls may be unknown and may provide indirect estimates of risk.
- The temporal relationship between exposure factor and outcome cannot always be determined. C For an observational designed study, the observer does not have control over the exposure factor. Mostly, cannot assign subjects by random to certain study conditions. For an experimentally designed study the observer can control who is exposed to certain factors and is able to assign subjects by random to certain study groups. Ans:- B 83 Describe the uses of analytic studies A They help lead to the prevention of disease, create quantitative evaluations of intervention programs as well as determine safe and effective new , and other procedures.
- B This is something that describes the negative because you cannot always take the findings from group data and apply it to individuals. C the units of analysis are groups. This can be referred to as an Ecological Comparison Study. Ans:- A 84 Identify an example of a case control study A are used very commonly in environmental epidemiologic research. An example may be possible health effects of exposure to electromagnetic fields.
- B Allowance of the direct observation of risk. The exposure factor is well defined and can study exposures that are uncommon in the population. The temporal relationship between factor and outcome is known. Ans:- A 85 Describe the advantages of the case control study A The ecologic fallacy and imprecise measurement of exposure. B it can be used to study conditions of low prevalence. The procedure is mostly quick and easy to complete, and is inexpensive. Lastly, the number subjects needed are smaller.
- C Refers to the difference between the incidence rate of a disease in the exposed group and the incidence rate in the non-exposed group. Attributable risk is the difference between two incidence rates. Ans:- B 86 Explain the ecologic fallacy A This is something that describes the negative because you cannot always take the findings from group data and apply it to individuals. B Conduct the program several times in a variety of settings with a variety of participants.
- C This refers to the adoption of policies, laws, and programs that are supported by empirical data. One of the most reliable forms of evidence will come from randomized controlled trials. Ans:- A 87 Contrast the 2 categories of analytic studies A For an observational designed study, the observer does not have control over the exposure factor. B This test can be used to test between two medical tests themselves. Which one is most efficient and yields the best results. C This is the association between two variables, the exposure and the outcome, and are measured at the group level. Ans:- A 88 Describe the ecologic correlation A It is the best because if the sensitivity test correctly identifies all potential cases as either negative or positive.
- B A clinical trial refers to a research activity that involves the administration of a test regimen to humans to evaluate its efficacy and safety. Ans:- C 89 Explain the ecologic study B the units of analysis are groups. C This is beneficial because an association can be found between exposure rates and disease rates during the same time period. Ans:- B 90 Describe the drawbacks of the ecologic study A are used very commonly in environmental epidemiologic research. B Mass screening is defined as the standards of care, anyone that could at risks should be screened for exposure. C The ecologic fallacy and imprecise measurement of exposure. Ans:- C 91 Describe the benefits of the ecologic study A the measurement of exposure may be inaccurate. B This is beneficial because an association can be found between exposure rates and disease rates during the same time period. Ans:- B 92 Explain the population risk difference A This is the difference between the rate of disease in the nonexposed segment of the population and the overall rate in the population.

B Where the investigator manipulates the study factor but does not assign individual subjects randomly to the exposed and non-exposed groups. C When sensitivity tests correctly identify all potential cases as either negative or positive Ans:- A Why is the gold standard considered the best A It helps to generalize the study to the population B The standard will help to conclude that the results were true C When sensitivity tests correctly identify all potential cases as either negative or positive Ans:- C What is external validity A This is the generalizing of the study to the population B Was the conclusion true?
