1. Define the following key terms used in epidemiology:
- Prevalence
- Incidence
- Attack rate
- Point prevalence
2. You were recently hired as an epidemiologist at a county office. List and explain three measures that you would use to calculate a specific disease situation. In your view, why is it difficult to get accurate information about disease status in a population?
3. A study starts with 4,875 health people. Over the next 2 years, 75 develop the disease. What is the incidence rate of disease over the study period? Show all work.
4. In a survey of 1,150 women who gave birth in Maine in 2000, a total of 468 reported taking a multivitamin at least 4 times a week during the month before becoming pregnant. Calculate the prevalence of frequent multivitamin use in this group.

- What patterns do you detect? Often in disease outbreak investigations we want to see a pattern for a particular problem. Think back to the 'white board' approach from a previous question and consider the types of information about individuals that may help you look for patterns. Select from the list below attributes that may help you You can chosse all or some I choose Time of disease onset and occuption but there is more I guess Occupation Hair color Gender Weight Age Time of disease onset5. Discuss the figure below. Give specific examples as needed: DESCRIPTIVE Describe a disease or health condition/phenomenon or intervention ANALYTIC Examine association (test of hypothesis) Experimental Exposure variables are assigned Observational Турes 1. Case reports/Case series Exposure and outcome variables are just observed 2. Prevalence survey (cross- sectional) 3. Ecologic study Турes 1. Cross-sectional Турes 1. Clinical trials 2. Case-control 3. Cohort 2. Field trials 3. Community intervention trials 4. Ecologic Hypothesis formulation Identification of risk/protective factors1. First, describe your chosen public health issues topic. a. Then, explain why you chose the topic. b. Finally, explain the topic’s relevance to public health. (We suggest citing reading and lecture material to demonstrate your understanding of public health.] [Minimum of 150 words] 2. Who is impacted by this issue, and why? a. Include epidemiological evidence, such as incidence or prevalence or population-based data, if it exists. b. Are certain populations more affected than others? c.Do health disparities exist? Explain. [Minimum of 150 words.] 3. How might different stakeholders (an individual or group with an invested interest in the topic ) understand the issue? [Minimum of 150 words.] a. Consider different parties like industry, government, healthcare, technology, various cultural groups, etc. You don’t have to describe each of these, but rather appreciate how any issue will include various perspectives. i.

- An epidemiologist recruits 250 people for a cohort study. Of these potential study subjects, 11 are prevalent cases. The remaining study subjects are followed for 5 years, during which time 21 individuals develop the disease being studied.What is the prevalence of disease at the start of the study Assume all of the cases are still around at the end of the study. What is the prevalence now and What is the incidence proportion over the period of observation?================================Community health nurses use epidemiological concepts to: a.Improve the health of population groups by identifying risk factors that reduce risk and promote illness. b.None of the answers. c.Epidemiological methods are not needed in assessment diagnosis, planning or evaluating community interventions. d.Epidemiologists are not concerned with interrelationships between host and environmental characteristics. ================================Which of the following is an epidemiologic function of the nurse during an epidemic? a.Conducting assessment of suspected cases to detect the communicable disease, and teaching the community on preventive measures against the disease. b.Teaching the community on preventive measures against the disease. c.Monitoring the condition of the cases affected by the communicable disease. d.Participating in the investigation to determine the source of the epidemic.Epidemiology 1. True or False: Prevalence is a measure of association used to estimate the rate of disease occurrence in studies of screening programs. 2. True or False: Incidence is a measure of disease frequency used to estimate the risk or rate of exposure in diagnostic test studies. 3. True or False: A number needed to screen of 20,000 would mean that for every 100,000 people screened, 5 would benefit. 4. True or False: A screening program with a number needed to harm of 1000 would be consistent with a risk of harm of 0.002 in the screening group and 0.001 in those not screened.
- Explain the relationship between the three levels of prevention and the prevalence and/or incidence of a specific disease of your choice in a specific population. What are the health disparities for this disease and population you chose? Which of the three levels of prevention do you think receives the most public attention and resource allocation to address this disease? What do you think the rationale is and why?B. One of the most memorable epidemiologic incidents in the Philippines was the sudden food poisoning of school children in Bohol which killed 15 children while 240 others being crippled. As an epidemiologist, you are tasked to go the place and conduct an independent epidemiologic analysis using retrospective cohort study design. Design a method following this design. Your method must answer the following specific questions: a. What will be your cohort groups? Define your cohorts. b. What questions/exposures will your survey instrument contain? c. How will you gather your data? d. How will you interpret your data? e. Provide a plausible causal narrative to your “theoretical data”In the context of a case-control study, a pro of recruiting incident cases rather than prevalent cases is: a. Incidence is easier to assess than prevalence b. Incidence provides a measure of the burden of disease at one “snapshot” in time c. Using incident cases allows researchers to account for case-deaths that would not be evident if only prevalent cases were considered d. None of the above
- c.2. Researchers are studying HIV prevalence using a cross-sectional study design. Which of the following factors may affect the researchers' assessment of HIV prevalence in their study population? Choose all that apply and explain your answer. a) Changes in HIV treatment b) Changes in HIV virulence (HIV virulence refers to the ability of the virus to cause disease) c) Population changes (e.g. migration) due to HIV infection, for example people who leave their community to live closer to physicians specialized in treating HIV d) Other factors which may affect survival of HIV-infected persons (e.g. changes in healthcare practices) e) Changes in HIV diagnostics f) Changes in HIV awareness and educationGive several examples of disease keys, diagrams, and scales that are widely used for disease assessment. Are any of these methods for quantifying amount of disease superior to other methods? Explain your answerTrue/False? Epidemiology is a field of study focused on the study of health and illness in human populations, patterns of health or disease, and the factors that influence these patterns.
