  • Global Patterns of Health, Disease and Death
    • Health is better in wealthier countries
      • Health is defined as your physical, mental and social well-being and the absence of disease
      • Varies in different parts of the world
      • difficult to measure, which makes it pretty difficult to compare the health of people in two places
        • There are health indicators: -life expectancy - infant  mortality etc
    • Global Morbidity Patterns are Different Depending on the type of Disease
      • MORBIDITY - illness
        • PREVALENCE - the total number of cases in a population at a particular time
        • INCIDENCE - the number of new cases in a population during a particular time period
          • Indicators of morbidity
            • PREVALENCE - the total number of cases in a population at a particular time
    • Morbidity Patterns of Infectious Diseases
      • Infectious disease morbidity in poorer countries
        • Malnutrition - reduces the body's ability to fight disease
        • Lack of lean water and sanitation - increases the spread of diseases
        • Overcrowded conditions in urban areas - increases the spread
        • Poor access to health care - people who can't access drugs to treat and prevent infectious diseases
        • Limited health education - people aren't well-informed about how they can avoid infectious diseases
        • Disease vectors - organisms that spread disease are more common in poorer countries
    • Morbidity Patterns of Non-communicable Disease
      • The reasons for high non-communicable disease morbidity in wealthier countries
        • Higher proportion of older people - if there are more old people more people are likely to suffer from diseases associated with old age
        • Unhealthy lifestyle - the risk of getting some diseases increases if you're over weight or obese, eat unhealthily and don't exercise enough
    • Mortality patterns depends on Morbidity and the ability to treat morbidity
      • Mortality means death
      • Mortality rate is how many people die in a population over a period of time - use rates to compare global patterns of death
      • The risk of dying from a disease is much higher in poorer countries because of
        • Malnutrition - reduces the body's ability to fight disease
        • Poor access to health - people can't access the drugs they need to treat the disease
    • Health and Disease are World issues
      • Infectious dieases can spread to other countries and can even spread around the world
        • Countries need to work together to help improve global health and prevent diseases spreading
          • Organisations like the WHO work with most Governments and in most countries to help eradicate and prevent disease
