Objective To develop an integrated health forecasting model as part of the International
Futures (IFs) modelling system.
Methods The IFs model begins with the historical relationships between
economic and social development and cause-specific mortality used by the Global
Burden of Disease project but builds forecasts from endogenous projections of these
drivers by incorporating forward linkages from health outcomes back to inputs like
population and economic growth. The hybrid IFs system adds alternative structural
formulations for causes not well served by regression models and accounts for changes
in proximate health risk factors. Forecasts are made to 2100 but findings are reported to
2060.
Findings The base model projects that deaths from communicable diseases
(CDs) will decline by 50%, whereas deaths from both non-communicable diseases
(NCDs) and injuries will more than double. Considerable cross-national convergence in
life expectancy will occur. Climate-induced fluctuations in agricultural yield will cause
little excess childhood mortality from CDs, although other climatehealth pathways were
not explored. An optimistic scenario will produce 39 million fewer deaths in 2060 than a
pessimistic one. Our forward linkage model suggests that an optimistic scenario would
result in a 20% percent increase in gross domestic product (GDP) per capita, despite
one billion additional people. Southern Asia would experience the greatest relative
mortality reduction and the largest resulting benefit in per capita GDP.
Conclusion Long-term, integrated health forecasting helps us understand the
links between health and other markers of human progress and offers powerful insight
into key points of leverage for future improvements.
