Infant Mortality: Annual number of children under 1 year of age who die per 1,000 live births Under 5 Mortality/5 yr Child Survival Life Expectancy at.

•Infant Mortality: Annual number of children under 1 year of age who die per 1,000 live births•Under 5 Mortality/5 yr Child Survival•Life Expectancy at birth (in years)•Prevalence (disease) : proportion of a population afflicted at a given point in time•Incidence (disease): number of new cases in a population during a specified time period (usually per year)•Disability Adjusted Life Years (DALY )•Total Fertility Rate•Maternal Mortality: number of deaths from pregnancy-related causes per 100,000 live births•Crude Birth Rate•Crude Death Rate•Population Growth Rate

Health Indicators

World 1960 126/1,000 live births


Good measure of overall health and community well-being. Structural factors affecting the health of entire populations have an impact on the mortality rate of infants. Especially useful in low income and middle income countries

Infant Mortality: Annual number of children under 1 year of age

who die per 1,000 live births



Under-five Mortality: Annual number of children dying between birth and

5 years of age who die per 1,000 live births

World 1960 48 years

World 2002 63 years

Lowest in Sub-Saharan Africa (46) and highest in Japan (78) for 2002. Good measure of socio-economic development.

Life Expectancy at Birth: Number of years a newborn would live subjected to the present mortality risks prevailing for each

age group in the population

Indicator that measures disease burden in a

population, taking into account premature mortality,

and disability caused by disease or injury

Disability-adjusted life years (DALY )

• Using 107 diagnoses, and 95% of the causes of disability• “Gold Standard” is living in a healthy state (Level of health =1,

Death=0), dying at 80 years old (men) or 82.5 years old (women)

• Years of Lost life (YLL)= years lost by premature death, ex. 64 for a boy who dies at age 16yo

• Time in which disability is experienced is given a severity rating (ex. Schizophrenia is a 0.8 loss, knee injury is a 0.1 loss) and that time added to YLL

• Age weights: value of a year lost rises steeply from birth (0.1) to 25 years old (1.4) and then decreases progresively: so for death as a newborn= 32.5 DALY value, at 30 years 29 =DALY value and death at 60 =12 DALY value.

• Years lost in the future are discounted, so that years lost now are worth more that years lost in the future, at a discount of 3% per year.

Calculating DALYS

1. Built in gender difference

2. Built in age preference

3. Discounting future years

4. Weighting severity of disability
