What is the primary purpose of public health surveillance?

  1. To monitor the health status of a population

  2. To identify and investigate disease outbreaks

  3. To evaluate the effectiveness of public health interventions

  4. All of the above


Correct Option: D
Explanation:

Public health surveillance serves multiple purposes, including monitoring the health status of a population, identifying and investigating disease outbreaks, and evaluating the effectiveness of public health interventions.

Which of the following is NOT a type of public health surveillance data?

  1. Vital statistics

  2. Laboratory data

  3. Environmental data

  4. Behavioral data


Correct Option: D
Explanation:

Behavioral data is not typically considered a type of public health surveillance data, as it is not collected through routine surveillance systems.

What is the difference between incidence and prevalence?

  1. Incidence is the number of new cases of a disease in a population over a specific period of time, while prevalence is the total number of cases of a disease in a population at a specific point in time.

  2. Incidence is the number of cases of a disease in a population over a specific period of time, while prevalence is the proportion of the population that has a disease at a specific point in time.

  3. Incidence is the proportion of the population that has a disease at a specific point in time, while prevalence is the number of cases of a disease in a population over a specific period of time.

  4. None of the above


Correct Option: A
Explanation:

Incidence and prevalence are two different measures of disease frequency. Incidence is the number of new cases of a disease in a population over a specific period of time, while prevalence is the total number of cases of a disease in a population at a specific point in time.

What is the purpose of a case-control study?

  1. To identify risk factors for a disease

  2. To evaluate the effectiveness of a public health intervention

  3. To monitor the health status of a population

  4. None of the above


Correct Option: A
Explanation:

Case-control studies are designed to identify risk factors for a disease by comparing cases of the disease to controls who do not have the disease.

What is the difference between a cohort study and a cross-sectional study?

  1. A cohort study follows a group of people over time to examine the relationship between exposure to a risk factor and the development of a disease, while a cross-sectional study examines the relationship between exposure to a risk factor and the presence of a disease at a specific point in time.

  2. A cohort study examines the relationship between exposure to a risk factor and the presence of a disease at a specific point in time, while a cross-sectional study follows a group of people over time to examine the relationship between exposure to a risk factor and the development of a disease.

  3. A cohort study follows a group of people over time to examine the relationship between exposure to a risk factor and the development of a disease, while a cross-sectional study examines the relationship between exposure to a risk factor and the presence of a disease at a specific point in time.

  4. None of the above


Correct Option: A,C
Explanation:

Cohort studies and cross-sectional studies are two different types of observational studies that are used to investigate the relationship between exposure to a risk factor and the development of a disease. Cohort studies follow a group of people over time to examine the relationship between exposure to a risk factor and the development of a disease, while cross-sectional studies examine the relationship between exposure to a risk factor and the presence of a disease at a specific point in time.

What is the purpose of a meta-analysis?

  1. To combine the results of multiple studies to provide a more precise estimate of the effect of an exposure on a health outcome

  2. To identify risk factors for a disease

  3. To evaluate the effectiveness of a public health intervention

  4. None of the above


Correct Option: A
Explanation:

Meta-analyses are used to combine the results of multiple studies to provide a more precise estimate of the effect of an exposure on a health outcome.

What is the difference between a relative risk and an odds ratio?

  1. A relative risk is the ratio of the incidence of a disease in an exposed group to the incidence of the disease in an unexposed group, while an odds ratio is the ratio of the odds of a disease in an exposed group to the odds of the disease in an unexposed group.

  2. A relative risk is the ratio of the odds of a disease in an exposed group to the odds of the disease in an unexposed group, while an odds ratio is the ratio of the incidence of a disease in an exposed group to the incidence of the disease in an unexposed group.

  3. A relative risk is the ratio of the incidence of a disease in an exposed group to the prevalence of the disease in an unexposed group, while an odds ratio is the ratio of the odds of a disease in an exposed group to the odds of the disease in an unexposed group.

  4. None of the above


Correct Option: A
Explanation:

Relative risk and odds ratio are two different measures of association that are used to assess the relationship between exposure to a risk factor and the development of a disease. Relative risk is the ratio of the incidence of a disease in an exposed group to the incidence of the disease in an unexposed group, while an odds ratio is the ratio of the odds of a disease in an exposed group to the odds of the disease in an unexposed group.

What is the purpose of a sensitivity analysis?

  1. To assess the impact of different assumptions on the results of a study

  2. To identify risk factors for a disease

  3. To evaluate the effectiveness of a public health intervention

  4. None of the above


Correct Option: A
Explanation:

Sensitivity analyses are used to assess the impact of different assumptions on the results of a study.

What is the purpose of a subgroup analysis?

  1. To examine the relationship between exposure to a risk factor and the development of a disease in different subgroups of the population

  2. To identify risk factors for a disease

  3. To evaluate the effectiveness of a public health intervention

  4. None of the above


Correct Option: A
Explanation:

Subgroup analyses are used to examine the relationship between exposure to a risk factor and the development of a disease in different subgroups of the population.

What is the purpose of a meta-regression analysis?

  1. To examine the relationship between the results of multiple studies and the characteristics of the studies

  2. To identify risk factors for a disease

  3. To evaluate the effectiveness of a public health intervention

  4. None of the above


Correct Option: A
Explanation:

Meta-regression analyses are used to examine the relationship between the results of multiple studies and the characteristics of the studies.

What is the difference between a systematic review and a meta-analysis?

  1. A systematic review is a comprehensive review of the literature on a specific topic, while a meta-analysis is a statistical analysis of the results of multiple studies.

  2. A systematic review is a statistical analysis of the results of multiple studies, while a meta-analysis is a comprehensive review of the literature on a specific topic.

  3. A systematic review is a comprehensive review of the literature on a specific topic, while a meta-analysis is a qualitative analysis of the results of multiple studies.

  4. None of the above

Explanation:

Systematic reviews and meta-analyses are two different types of research studies that are used to synthesize the evidence on a specific topic. A systematic review is a comprehensive review of the literature on a specific topic, while a meta-analysis is a statistical analysis of the results of multiple studies.

What is the purpose of a scoping review?

  1. To identify the key concepts and research questions related to a specific topic

Correct Option: A
Explanation:

Scoping reviews are used to identify the key concepts and research questions related to a specific topic.
