Objectives
To use data from the Global Burden of Diseases,
Injuries, and Risk Factors Study 2019 (GBD 2019)
to estimate mortality and disability trends for the
population aged ≥70 and evaluate patterns in causes
of death, disability, and risk factors.
Design
Systematic analysis.
Setting
Participants were aged ≥70 from 204 countries and
territories, 1990-2019.
Main outcomes measures
Years of life lost, years lived with disability, disability
adjusted life years, life expectancy at age 70 (LE-
70), healthy life expectancy at age 70 (HALE-70),
proportion of years in ill health at age 70 (PYIH-70),
risk factors, and data coverage index were estimated
based on standardised GBD methods.
Results
Globally the population of older adults has increased
since 1990 and all cause death rates have decreased
for men and women. However, mortality rates due
to falls increased between 1990 and 2019. The
probability of death among people aged 70-90
decreased, mainly because of reductions in non communicable diseases. Globally disability burden
was largely driven by functional decline, vision and
hearing loss, and symptoms of pain. LE-70 and HALE-
70 showed continuous increases since 1990 globally,
with certain regional disparities. Globally higher LE-70
resulted in higher HALE-70 and slightly increased
PYIH-70. Sociodemographic and healthcare access
and quality indices were positively correlated with
HALE-70 and LE-70. For high exposure risk factors,
data coverage was moderate, while limited data
were available for various dietary, environmental or
occupational, and metabolic risks.
Co nclusions
Life expectancy at age 70 has continued to rise
globally, mostly because of decreases in chronic
diseases. Adults aged ≥70 living in high income
countries and regions with better healthcare access
and quality were found to experience the highest life
expectancy and healthy life expectancy. Disability
burden, however, remained constant, suggesting
the need to enhance public health and intervention
programmes to improve wellbeing among older
adults.
