public health + demography Flashcards
3 main indices for public health
- demographic
- disease incidence ( incidence and prevelence)
- physical activiity
The main objections of social medicine
studying the health of the population (public health and its determinants)
health education and promotion
health policies, legislation
health ecomonic
intergrating with other medical sciences with regional natianonal and international
demography and static
2 main braches 1.static 2.dynamic
static: studying the Size distribution and structure of the population by age and gender and other factprs primarily achieved through a census the different types are constrictive expansive and stationary
census in bulgaria
national statiscial institue of bulgaria - organization
last one was 2011
and now 2021
population was - 7, 364, 570
dynamics
studies the changes in the population and how these changes influence the population
Looks at natural and vital events such as births deaths marriages divorces and
migration
migration
forced
voluntary
internal
external
WHAT MAKES UP DEMOGRAPHY
population stastics
population dyanmics
population dyanmics
part of demolgraphy
The study of changes in the population and the processes influencing those changes.
Determined by bio-social phenomena
a) Natural events – births, deaths, marriages, divorces =Net Increase
b) Migration – emigration, immigration = Net Migration
when was the demographic transition model first described
1940’s
types of internal migration
- permanent
- urbanisation
-urban depopulation
-regional migration ( a general trend of permanent movement within a country) - temporary
- daily (school, work)
-seasonal , seasise, winter employment
-semi permanent ( limited work in a diff country)
WHAT IS THE PROBLEM WITH MIGRATION
EXTERNAL : changed in the diseas epidemiology you can bring new diseases to areas that never saw it before, and thefreors globabl pandemics like ebola
internal :
overpopulation or depopulation
seasonal peaks in disease like food posioning in summer and drowingn
Requirements for vital registration
Continuous
Complete
Permanent
Compulsory
Items for registration
Age
Sex
Date and place of occurrence of the event
Date of registration
Place of residence
types of population
depends on which age group is in higher numbers
expansive - 0-14
constrictive = 50+ (bulgaria )
stationary = 15-49 , br roughly equals death rate
new censesu
decrease in population between the 2011 and 2021
censuses was the largest so far among recent counts.
Most of this decrease, 53 per cent, is due to negative demographic trends, higher mortality than the birth rate and the negative natural increase, as well as people who left the country and did not return,” she said.
2011- 7 364 570
2021- 6 916 548.
