Changes between WDR93 and
GBD96 are substantial. WDR93 estimates
put more than 50% of disease burden in
the age group 0-4 years and another 20%
in the elderly above 60 years. The burden
on adolescents and adults (5 to 44 years)
was estimated at 15%. This pattern is
maintained if we look at the
distributions separately for females and
males. The GBD96 estimates put the burden
on 0-4 year olds at the reduced level of
35%. The burden on adolescents and adults
turned out to be higher at 40%. The two
HSV anchored estimates, however, put the
burden on adolescents and adults at 50%,
a situation just opposite the age
distribution obtained by the WDR93
estimates. |

According to WDR93
estimates, premature mortality is the
dominant burden over all age groups. The
YLL to YLD ratio range from 1.6 to 5.6.
According to the GBD96 and COD anchored
estimates, premature mortality is the
dominant source of disease burden for all
age groups, except in the age group 5-14
years and adult females in age group 15
to 44. In these later age groups, the YLL
to YLD ratio range is from 0.5 to 0.6.
Premature mortality is the major
contributor to disease burden among
infants and children in age group 0 to 4
years and the elderly at ages 60+ years.
This is consistent with our understanding
of the pattern of general mortality,
concentrated among the infants and then
the elderly. According to the two HSV
anchored estimates, disability becomes
the dominant source of disease burden at
all ages, except the elderly group at 60+
years. Here also, the YLL to YLD ratio is
quite low between 1 to 2. Here again we
find that the GBD96 and COD anchored
estimates are intuitively appealing and
are consistent with our knowledge of
general mortality pattern. The two HSV
anchored estimate produces unacceptably
low YLL to YLD ratios. If these estimates
were to inform policy, then premature
mortality reduction would get a back seat
altogether. |
