- True/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.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. noWhich of the following are true regarding direct causes of diseases? Check all that apply Direct diseases are easier to understand thanindirect diseases.Direct diseases are caused by lifestyledecisions.Direct diseases have no interferencesbetween the disease and the person.Direct diseases can be caused byenvironmental factors such as the sun
- What is an endemic disease? A disease of which there are only a few scattered cases in a population or geographical area When a disease occurs at a greater frequency than normal When a disease occurs simultaneously on more than one continent A disease that occurs continually within a population or geographical areaCalculating 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.1. The leading cause of death worldwide is 2000 is due to 1) none 2) congenital disease 3) lifestyle risk factors 4) communicable disease 2. To differentiate incidence from prevalence: 1) whether the event is a new case ; time of onset of the disease 2) presence or absence of a disease ; time period is arbitrary ; rather a snapshot in time 3) number of new cases of disease during a specified period od time/population at risk 4) useful in the study of burden of chronic diseases and implications for health services
- 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?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.Based on the graph, how would a chronic disease and latent disease graph look like. Please include a picture, I’m a little confused
- What is a notifiable disease? Group of answer choices A disease that is highly contagious. A disease that must be reported to the CDC. A disease that has a high mortality rate A disease that is suspected to be caused by terrorists.Which of the following is false about disease burden? a.The burden of disease globally has shifted increasingly toward noncommunicable diseases b.The years of life lost due to diabetes has been increasing c.The years of life lost due to premature death of children has been decreasing d. The burden of disease globally has shifted increasingly toward communicable diseasesClinical decisions are made about individual patients; epidemiological decisions are made about populations. The goal of epidemiology is to measurably identify the determinants of illness or disease in a target population. Consider how information on health determinants, types of data, frequency, distribution, & variation of data, as well as other factors, can contribute to the process of health outcomes.
