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.

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.

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).

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

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

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 ## Footnote 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

provides the necessary data upon which a program may be based; to guide the program, assessing its progress and pinpointing failures, etc.

To study immediate and special problems in the field of health

→ clinical trials → evaluation research

To evaluate the effectiveness of therapy, preventive measures and programs

# Epidemiology as a Method of Gaining Knowledge - T or F The sampling method has various dimensions, depending on its objectives, approaches and tools used.

epidemiologic

# Epidemiology as a Method of Gaining Knowledge Based on its objectives, epidemiologic studies may be classified as?

* Surveillance * Epidemiological Investigagtion * Research

# Epidemiology as a Method of Gaining Knowledge it is any method or methods used to arrive at an epidemiologic synthesis of information.

Epidemiologic method

# T or F Epidemiologic methods are used in all fields of todoroki

F, endeavor

Epidemiologic method are synonymous with?

cientific investigative method

# T or F Broadly, these principles are the clear statement of the problem in their entirety, the formulation of suitable solutions or answers, and the evaluation of such solutions.

T | solution to answers, KORIK

# T or F The lack or very inadequate epidemiological basis of plans/programs consequent to a defective planning methodolog

# T or F Epidemiology can not utilize any other discipline of learning order to achieve its aims | bawal umapak ng tao typa thing

F | they can, because of the gravity inside the popcorn

# T or F Epidemiologic method can employ clinical medicine, laboratory techniques, statistics, sociology, anthropology, meteorology, and other various related fields.

T ## Footnote Epidemiology can utilize any other discipline of learning order to achieve its aims

What are the 2 most basic method for epidemiological method

* Statistics * Clinical Medicine

focus of observation is a group

Statistics

make diagnosis, assess effects of drugs and other factors on health

Clinical medicine

* Practices in the field of Medicine and Public health * Medical * Non-medical * (necessary training, and previous actual work experience and exposure in the field)

Epidemiologist

# according to yt The study of the distribution of health outcomes or disease within populations

Epidemiology

determine spread of health outcomes and diseases

Factor

determines someone will get certain health outcome or disease

Risk factor

Focuses on Population, rather than Individual level

Epidemiology

# T or F People have long viewed epidemic of disease and plagues as terrifying occurrences

T | wow so scary

what bloomed because of scary plauges and diseases

continued desire to have a more rational and complete way to explain the disease | thus epidemiology

# T or F epidemiology was a result from believing that diseases were simply caused by spirits or God

T | uto uto typa things

what was the BEGINNING of epidemiology

Empirical observation of epidemics and other causes of mortality | genesis 1:1 "in the beginning" char

# T or F epidemiology focus was initially on infectious diseases until the early 20th century, towards the end of 20th century computers increasing IT, new methodological approaches altered the field of Epidemiology

T | haba teh true nayan

become a standard area of clinical science and is the most fundamental basic science of public health

Epidemiology <3 my hearteu uwu

# Evolution of Epidemiology The focus are on Infectious diseases and epidemics

1873 – mid-1800

# Evolution of Epidemiology The focus in on infectious disease overall

1927 – mid-1900

# Evolution of Epidemiology 1951 – mid-1950s

The focus is now one condition associated with infectious processes

# Evolution of Epidemiology 1962 – 1960s

Focus on the distribution of diseases at a community level

# Evolution of Epidemiology Focus is on how to control or minimize health problems and diseases

1988 – late 1980s

describes changing patters of population – age, mortality, fertility, life expectancy and causes of death

Epidemiologic Transition

How many epidemiologic transition human undergo?

Four (5-1 = 4) | 4 ## Footnote apat

# Epidemiologic Transition Emergence Infection and nutritional diseases

Epidemiologic Transition One (1st transition)

# Epidemiologic Transition - Because of the beginning of agricultural practice 10,000 years ago, people became less dependent on hunting - This lead zoonotic diseases, nutrient deficienceies and increased contact with disease vectors, during agricultural activity

Epidemiologic Transition One (1st transition)

# Evolution of Epidemiology Human immune systems and disease-causing organisms evolved

Epidemiologic Transition Two (2nd Transition)

# Evolution of Epidemiology - Resulting to change from major epidemics to endemic diseases - Humans developed physical and genetic changes that serve to minimize the effect of diseases

Epidemiologic Transition Two (2nd Transition)

# Evolution of Epidemiology The disease pattern change to chronic and degenerative diseases

Epidemiologic Transition Three (3rd Transition)

# Evolution of Epidemiology - In developed parts of the world due to improvements in nutrition, public health, and clinical medicine - Cardiovascular diseases and cancer began to occur more during this transition, associated with longer lifespan and sedentary lifestyle

Epidemiologic Transition Three (3rd Transition)

# Evolution of Epidemiology Started at the end of 20th century, when both new diseases and re-emergence of infectious diseases, and rapid spread through globalization of diseases

Epidemiologic Transition Four (4th Transition)

If u see this card

review the four epidemiologic transition and resulting change

Hunter-gathere to cities | Started when agriculture started and began to live in one place

From few epidemic to major epidemics

Immunologic resistance and organism change | population developed immunologic resistance and disease organism change

From major epidemics to endemic diseases

Public health and Sanitation | Started from improve public health and sanitation

From infectious diseases to non-infectious–chronic degenerative diseases

Increased Globalization | Started due to increased globalization

Resurgence and rapid spread of infectious diseases
