Chapter 5Q#1. Describe the three uses (i.e., aims) of descriptive epidemiology and explain your answers inrelation to the following health issue: “The obesity in the United States” (0.66 pts)- Descriptive epidemiology is defined as the epidemiological studies and activities with descriptive components that are much stronger than their analytic components or that fall within the descriptive are of descriptive analytic spectrum. This includes the 5ws of descriptive epidemiology the what (health event/diagnoses), person (who), place (where), time (when) and causes, risk factors and modes of transmission aka the why/how. Specifically concerning obesity in the US the uses include: studying the variation of obesity and its frequency in the US, organizing and analyzing data, and accounting for how many people are affected by obesity and predicting how many morecan be expected to face it are all aims of the use of descriptive epidemiology in confrontation with obesity in the United States. Q#2. Describe the following descriptive epidemiological study designs includingadvantages/disadvantages and explain their applications using the examples that are not discussed inthe textbook. You will need to search an internet for an appropriate example, and when you refer to thesources, make sure that you identify them appropriately. (0.66pts)a) Case report (or case series)b) Cross-sectional studyChapter 6Q#3. Describe the following causality models and explain using your own example. (0.66 pts)a) deterministic model of causality (note. include the four combinations of causality model andexplain)b) probabilistic causality modelQ#4. Describe the Hill’s criteria of causality as described in the textbook. Choose THREE criteria that youthink the most critical to establish the cause-and-effect relationship and explain your reasonings. (0.59pts)Chapter 7Q#5. Describe the following descriptive epidemiological study designs including theiradvantages/disadvantages (note. you do not need to provide an example for each for this question).(0.66 pts)a) Case-control studyb) Cohort-study design (retrospective and prospective).c) Experimental designQ#6 - #8) We are interested in investigating the following research question: “what effect does physicalactivity have on obesity among college students”. Develop three research plans based on 1) casecontrol study; 2) cohort study; and 3) experimental study designs. Make sure that you provide detaileddescriptions/explanations of your designs – always try to explain ‘why’.Q#6. Case-control study design: (0.59 pts) describe how you will select ‘case’ and ‘control’ groups describe how you will measure the exposure and outcome (i.e., operationalization) describe what numerical information (i.e., measures of association) you will obtain from thestudy to address the research question)Q#7. Cohort-study design: (0.59pts) be sure to describe the type of cohort study designs (e.g., retrospective, prospective) describe who are the population-at-risk and how the cohort sample will be selected describe how the exposed group will be determined describe how long the cohort will be tracked and how you will determine the outcomestatus describe what numerical information (i.e., measures of association) you will obtain from thestudy to address the research question)Q#8. Experimental design: (0.59 pts) include the type of experimental study design (e.g., randomized controlled trial, quasiexperimental study) describe an overview of study process such as recruitment, group assignment, experimentalcomponent (e.g., how you will manipulate the exposure status), outcome measure, whatnumerical information you will calculate to address the research
