10. Compression, expansion, or dynamic equilibrium? The evolution of health expectancy in New Zealand (2004)
Patrick Graham, Tony Blakely, Peter Davis, Andrew Sporle, Neil Pearce
The study aims to evaluate the New Zealand evidence for three theories of population health change: compression of morbidity, expansion of morbidity, and dynamic equilibrium. Using the Sullivan method, repeated cross sectional survey information on functional limitation prevalence was combined with population mortality data and census information on the utilisation of institutional care to produce health expectancy indices for 1981 and 1996.
