whom definition of epidemiology
Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.
Last JM, editor. Dictionary of epidemiology. 4th ed. New York: Oxford University Press; 2001. p. 61.
whom definition of epidemiology
“a science concerned with the various factors and conditions which influence the occurrence and distribution of health, disease, defect, disability, and death among groups of individuals.”
Hugh R. Leavel and E. Gurney Clark, Preventive Medicine for the Doctor in the Community (New York, McGraw-Hill Book Compony, Inc., 1958 p.41)
The present usage includes studies of all conditions and circumstances important to man’s health
Epidemiology
e.g., accidents, suicides, medical care, diseases, and administrative problems, etc.
what are the uses of Epidemiology
- Assessing the community’s health
- Making individual decisions
- Completing the clinical picture
- Searching for causes
- To study immediate and special problems in the field of health.
- To evaluate the effectiveness of therapy, preventive measures, and programs.
Public health officials responsible for policy development, implementation, and evaluation use epidemiologic information as a factual framework for decision making.
Assessing the community’s health
Assessing the community’s health - T or F
To assess the health of a population or community, non relevant sources of data must be identified and analyzed by person, place, and time (descriptive epidemiology).
F
Relevant resources only
use this card to familiarize what questions is asked for Assessing the community’s health when usong decriptive epidemiology
- What are the actual and potential health problems in the community?
- Where are they occurring?
- Which populations are at increased risk?
- Which problems have declined over time?
- Which ones are increasing or have the potential to increase?
- How do these patterns relate to the level and distribution of public health services available?
Assessing the community’s health - T or F
More detailed data may need to be collected and analyzed to determine whether health services are available, accessible, effective, and efficient
T
E.g. public health officials used epidemiologic data and methods to identify baselines, to set health goals for the nation in a certain year and to monitor progress toward these goals
in 1950s what did epidemiologists reported?
increased risk of lung cancer among smokers.
in 1970s what did epidemiologists documented?
the role of exercise and proper diet in reducing the risk of heart disease.
in mid 1980s what did epidemiologists identified?
the increased risk of HIV infection associated with certain sexual and drug- related behaviors
Using epidemiologic information to make daily decisions affecting health.
Making individual decisions
Making individual decisions - T or F
they may be influenced, consciously or unconsciously, by epidemiologists’ assessment of risk
T
When investigating a disease outbreak, epidemiologists rely on health-care providers and laboratorians to establish the proper diagnosis of individual patients.
Completing the clinical picture
To construct or complete the natural history of a disease
Completing the clinical picture - T or F
Epidemiologist does not contribute to physicians understand of the clinical picture and natural history of disease.
F
they do contribure
E.g. In late 1989, a physician saw three patients with unexplained eosinophilia and myalgias .
Much epidemiologic research is devoted to searching for causal factors that influence one’s risk of disease
Searching for causes
ideally, the goal is to identify a cause so that appropriate public health action might be taken.
Searching for causes
Searching for causes - T or F
One can argue that epidemiology can never prove a causal relationship between an exposure and a disease, since much of epidemiology is based on ecologic reasoning. Nevertheless, epidemiology often provides enough information to support effective action.
T
please go over the example for this sankyu
study of new diseases, endemic disease problems, epidemics, special events
To study immediate and special problems in the field of health
situations (situational analysis in health planning) conditions or occurrences, and implementation problems (operational research)
To study immediate and special problems in the field of health
