Impact of Ageing and Degeneration Flashcards
What determines population growth and decline?
- Birth rates
- Death rates
- Migration
What is demographics?
-Scientific study of human populations, especially with reference to their size structure and distribution
What is the demographic transition?
- Transition from high birth and death rates to low birth and death rates
- Or as a country develops from a pre industrial to an industrialised economic system
What happens before and after the demographic transition?
-Before: birth rates and death rates high low life expectancy smaller population Low population growth -After: birth and death rates low high life expectancy larger population population growth low or declining
What are WHO’S 6 DOMAINS OF quality of life?
- Physical
- Environment
- Psychological
- Spiritual
- Social relations
- Level of dependance
What is the epidemiological transition?
-Long term shift in the pattern of disease in a country from infectious disease towards degenerative disease
What is population ageing?
- Is an increasing median age in a population due to declining fertility rates and rising life expectancy.
- Most countries have rising life expectancy and an ageing population.
How may life be added to the years we have?
- Healthy habits from young
- Good healthcare
- Old at heart of community
- Understand old peoples needs
What is wellbeing?
- Integrates mental health and physical health resulting in more holistic approaches to disease prevention and health promotion.
- Valid population outcome measure that tells us how people percieve their life is going from their own perspective.
What is the impact of chronic MSK conditions on life quality?
- Leading cause of chronic disease mortality
- Long term pain
- Sleep disturbance
- Drug side effects
- Activity limitation
- Exacerbate symptoms of depression and anxiety
- Social interactions
- Accessebility problems
What is compression of mortality?
-A greter proportion of deaths occuring during a narrow time period at upper limit of human life span.
What is compression of morbidity?
-Optimistic scenario where increasing proportion of the population will live a long, healthy life in which death will be precedded by a very short period of ill health.
What is incidence rate of disease?
-The no. of new events occurring in a specified time period in a defined population
What is prevalence of disease?
-The no. of cases of disease or other health outcome present in a specific time period in a defined population
What is health ageing?
- As we age, the risk of disease and death increases
- Ageing is associated wit ha progressive, generalised impairment of functioning resulting in a loss of adaptive response: lung function, circulation, muscles, nerves, immune system etc.
