- incidence reflect the likehood of developing a disease among a group of participants free of the disease who are considered at risk of developing the disease over a specified observation period; prevalence involves estimating the proportion of people who havee disease at point of time .true or false?matching type Which groups in an observational study design should NOT have significantly higher proportions to show an association between exposure and outcome? * coloumn a coloumn b Exposed - do not have the disease Unexposed - have the disease Unexposed - do not have the disease Exposed - have the disease a. yes b. noCross-sectional surveys measure:A. The prevalence of various demographic characteristics in a well-defined populationB. The exposure histories of a well-defined populationC. The disease states in a well-defined populationD. All the above
- Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the period prevalence from October 1, 2004, to September 30, 2005. The numerator of period prevalence includes anyone who was ill any time during the period. In Figure 3.1, the first 10 persons were all ill at some time during the period.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?refer to the provided image 80. Which of the following is represented by the x-axis of the provided epidemic curve?A. Asymptomatic timeB. Generation time C. Incubation periodD. Natural history 81. What type of epidemic is evident on the given epidemic curve?A. IntermittentB. Point-source C. ProgressiveD. Propagating
- In an epidemiological study with human subjects, the relationship between the independent variable and the dependent variable always suggests that: Answer choices one does not cause the other. correlation always equals causation. one caused the other. correlation does not always equal causation.Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the incidence rate from October 1, 2004, to September 30, 2005, using the midpoint population (population alive on April 1, 2005) as the denominator. Express the rate per 100 population.In a cohort study, the ratio of the incidence rate of a disease in an exposed group to the incidence rate of the disease in a nonexposed group is the: a. Relative risk b. Risk difference c. Prevalence ratio d. Odds ratio
