Measuring inequities in health over the lifecycle: age-specific or lifecycle perspective?
Sandy Tubeuf will deliver this talk entitled 'Measuring inequities in health over the lifecycle: age-specific or lifecycle perspective?'.
This seminar will talk about the issue of measuring health inequality over the lifecycle and measures inequalities of opportunities in health in Britain over the lifecycle. We propose a methodology, which captures the lifecycle and aged-specific perspectives. The lifecycle perspective measures inequality over the lifecycle by firstly aggregating health over ages at the individual level and then measuring inequality over individuals. The other perspective measures health inequality over individuals at each age and then aggregates the inequality measure over ages. We use data from the National Child Development Study (NCDS), which follows for a cohort of 17,500 British people born in one week in March 1958 in England, Scotland and Wales. The cohort study is the only data source that allows us to measure health using self-assessed health at repeated ages (age 23, 33, 42, 46, 50 and 54) combined with vital status at each time point. Death is ranked as obviously the worst health status. We use first order stochastic dominance and Hammond dominance criteria to rank social states according to an inequality viewpoint. Our results show that the two perspectives impact on the existence and the magnitude of inequalities of opportunities in health in the UK. We can detect (i) a change in the dynamic of inequality of opportunity favouring people born in South-East UK in the second part of their lifecycle, (ii) a reinforcement of inequality of opportunity between regions over lifetime. This is particularly striking in the context of the NHS.
