The average number of eggs consumed during a typical week was measured among all employees who work for a state agency. They were followed up for 3 years, and the incidence of chronic heartburn was compared at the end of the follow-up between those who consumed 0-4 eggs per week and those who consumed 5 or more eggs per week.

To test the efficacy of vitamin C in preventing colds, army recruits were randomly assigned to one of two groups: 500 mg of vitamin C daily and a placebo (sugar pill) daily. Both groups were then followed for a year to determine the number and severity of subsequent colds. What type of study design is it?

A study was conducted by the NIH (National Institute for Health) with a large population that examined smoking and the occurrence of lung cancer. In the duration of the study period, 1,800 smokers developed lung cancer. In the same period, 200 nonsmokers developed lung cancer. There were 241,800 current smokers and 478,000 nonsmokers in the total study population. 1.what type study ?

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 onset
You enrolled 6,500 men in 2005 and followed them for 10 years. Liver cancer is your outcome; none of the men had liver cancer at the start of the study. Of those men who drank alcohol daily (n=2,000) starting in 1990, 50 were diagnosed with liver cancer during the 10-year period. Of those who abstained from alcohol in 2005, 50 had liver cancer diagnosed during the 10-year period. Nobody died or was lost to follow up during the study period. Complete the standard epidemiology table. Include the numbers and the proper headings. 2x2 table Liver Cancer No liver Cancer Total Drink Alcohol 50 1950 2000 Did not drink 50 4450 4500 Total 100 6400 6500 1. Liver cancer has multiple causes other than alcohol consumption. Let’s say we wanted to think about whether chronic Hepatitis B infection was a confounder in the relationship between alcohol consumption and liver cancer. List the 3 criteria it would have to meet in order to be considered a…

I. STUDY DESIGNS IN EPIDEMIOLOGY: Answer the questions subsequently. A. Suppose you want to determine whether pesticide-use can cause cancer to farmers, I want you to design a method using the longitudinal cohort study 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” 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…
