Human Geography Notes: Health
Why do we study health?
1. Mapping of diseases
2. Planning in healthcare systems
3. Spread of illness
4. Effects of diseases
Epidemiological Transition Model
An epidemiological transition model shows how over time, pestilence and famine mortality is
decreased and more people are dying due to degenerative and human induced diseases.
Pros Cons
Shows patterns of mortality and Doesn't give a timescale
morbidity through time Different patterns for differences in
Countries can see where they are and wealth, religion, social status etc.
plan for the future Variations in model so can't be applied
No extension after 4
Links personal pestilence and famine-
puts them together
This model means that countries can plan ahead for the future in areas such as healthcare needs.
Governments and healthcare and medicine suppliers can decide where to allocate funds. It provides
the framework for health and healthcare strategies.
Global patterns of death, disease and health
LEDC's = young populations = low DR
MEDC's = ageing populations = high DR
Causes of death
Cancer Perinatal conditions- poor maternal
Alzheimer's disease health and nutrition, inadequate care
Diabetes Infectious diseases
Associated with older people and linked to
higher standards of living and unhealthy diets
Morbidity is measured in DALY's (daily adjusted life years) which is the amount of health lost due to a
disease or a condition. The highest DALY's are found in MEDC's.
Lifestyle (blood pressure + stress) Nutrition (underweight)
Physical inactivity Environment (unsafe water)

Life Expectancy
Higher life expectancy in MEDC's but there are some exceptions:
A higher GDP doesn't always mean a higher life expectancy
Women have higher life expectancies than men. The difference between sexes changes
from country to country
Well-educated professionals have higher life expectancies than manual workers
Different racial and ethnic groups differ
Factors affecting life expectancy include: nutrition (diet and food supply); living standards (availability
of clean water) and level of health care.…read more
