    Study Notes

    Mortality, Morbidity, and Burden of Disease

    • Mortality refers to death at a population level.
    • Maternal Mortality refers to death of a mother during pregnancy, childbirth or within six weeks of delivery.
    • Morbidity refers to ill health in an individual and the levels of ill health in a population or group.
    • Burden of Disease is a measure of the impact of diseases and injuries, specifically measuring the gap between current health status and an ideal situation, where everyone lives to an old age free of disease and disability.
    • Disability Adjusted Life Years (DALYs) are a measure of burden of disease. One DALY is equal to one year of healthy life lost due to premature death and time lived with illness, disease or injury.

    Useful Measures for Health Status

    • Years Lost Due to Premature Death (YLL) measures how many years of expected life are lost due to premature death.
    • Years Lost Due to Disability (YLD) measures how many healthy years of life are lost due to illness, injury, or disability.
    • Life Expectancy is an indication of how long a person can expect to live, based on current death rates.
    • Health Adjusted Life Years (HALE) is a measure of the burden of disease based on life expectancy at birth, including an adjustment for time spent in poor health. It measures the number of years in full health that a person can expect to live.
    • Self-assessed Health Status is a measure based on a person's own opinion about their health and wellbeing, including their state of mind and their life in general. Often sourced from population surveys.
    • Incidence is the number of new cases of a condition during a given time period.
    • Prevalence is a measure showing the number of cases of a particular disease or condition present in a population at a given time.
