DISABILITY- Disability-Adjusted Life Years (DALYs) represents the total
ADJUSTED burden of the diseases and injuries. The DALY for each

LIFE YEARS disease and injury was calculated by total sum of the Years
of Life Lost (YLL) and Years Lost due to Disability (YLD) for
(DALYs) the disease or injury. The burden of disease of a disease
group was calculated by total sum of the DALYs across all the
diseases or injury in the group. The total burden of disease
was calculated by summing the DALYs across all conditions.

DALYs = YLL + YLD

HEALTH- In this report, we used Sullivan’s method to calculate Health-
ADJUSTED LIFE Adjusted Life Expectancy (HALE) (described by Jagger et al.

EXPECTANCY 2006). This method is simple and intuitive. Sullivan’s method
requires age-specific proportions of time spent in different
(HALE) states of health and age-specific mortality information from
a life table. Measures of HALE are calculated by adjusting
estimates of the life expectancy of the population of interest
proportionately to the average health of individuals in each
age group.

where:
HALE is health-adjusted life expectancy
x is the exact age for which life expectancy or HALE is to be
estimated
s refers to sex
L refers to the number of person-years lived in the age
x,s
group x, for sex, s
L’ refers to the health-adjusted number of person-years
x,s
lived in the age group x, for sex, s
