The best way to understand the epidemiologic triangle is to see how epidemiologists use it to explain the spread of existing diseases. Life expectancy tends to be shorter for those who smoke, and smoking-related diseases are considered to be the leading preventable cause of death in the United States.

WebTerms in this set (66) 1) Physical 2) Chemical 3) Biological 4) Genetic 5) Nutrient 6) Psychological In other words, epidemiology is a branch of medicine that analyzes where diseases and other health factors originate, how they spread and how to possibly control them. A control or "no disease" group is needed for study on risk factors associated with oral cancer. Exercise 1.8. (Select all that apply.)

The agent infects the host, which is the organism that carries the disease. In Figure 1.17, it would be represented by component cause A. A host doesnt necessarily get sick; hosts can act as carriers for an agent without displaying any outward symptoms of the disease. WebThis is the same technique that epidemiologists use when they are researching the outbreak of a disease. WebThe goal of an epidemiologist is to decipher the connection between any of these three main factors. Person: personal characteristics of interest in epidemiology include race, ethnicity, sex, age, education, ocupation, income (and related socioeconomic status), and marital status. What is one aspect of this type of outbreak that presents substantial challenges to persons working in a local public health department like John's?

Which study design best describes her study? The premise is that changes in one of the elements of the triangle can influence the occurrence of disease by increasing or decreasing a person's risk. It is used by veterinarians, laboratorians, soldiers, and others who may be at increased risk of exposure, but is not available to the general public at this time.

"Black Feminist Theory in Prehistory." With regard to non-infectious disease, disability, injury, or death, agents can include chemicals from dietary foods, tobacco smoke, solvents, radiation or heat, nutritional deficiencies, or other substances, such as poison. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. Figure 4.

The table below listed a genotype associated with the lac operon in E. coli. The measurement of disease frequency relates to the quantification of disease occurrence in human populations. Susceptibility and response are both influenced by factors like genetic composition, physiological make up, and health behaviors such as nutrition and exercise (CDC, 2012). How common is anthrax and where is it found? Hosts get sick or carry an agent because some part of their physiology is hospitable or attractive to the agent. Describe six commonly occurring examples of the use of methods and techniques of descriptive epidemiology. All information these cookies collect is aggregated and therefore anonymous. He has been asked to work with the team that does outbreak investigations and conducts surveillance. She has collected data on the number of new cases among the contacts of initial (primary) cases, divided it by the number of people in the population at risk, and then multiplied it by a given multiplier. The inhalation form is from breathing in spores from the same sources. From an epidemiological perspective these are: When comparing the body mass index (BMI) of obese women in two cities, John found that the average BMI of City A was higher than that of City B. The triad is used to determine the cause of infectious diseases, non-infectious diseases, and accidents or injuries. Presence of Pneumocystis carinii organisms is therefore a necessary but not sufficient cause of pneumocystis pneumonia. The next step to investigate potential interrupting factors to break the sides of the triangle, or whatever connects each of the vertices. Yin is a nurse in a rural primary care clinic. Here, we demonstrate that O 3 exposure impaired the ability of microglia, the brains parenchymal immune cells, to associate with and form a protective barrier around A plaques, leading to augmented dystrophic neurites and increased A plaque load. endobj
