Abstract
AbstractObjectivesTo estimate the potential impacts of unmitigated and mitigated cost of living increases on real household income, mortality, and mortality inequalities in Scotland.DesignModelling study.SettingScotland, 2022/23.ParticipantsA representative sample of 5,602 Scottish individuals (within 2,704 households) in the 2015/16 Family Resources Survey. We estimated changes in real household income associated with differential price inflation (based on proportion of household spending on different goods and services, by income group), both with and without mitigating UK Government policies, and scaled these to the Scottish population. We estimated mortality effects using a cross-sectional relationship between household income and mortality data, by deprivation group.InterventionsBaseline was Scotland in 2022/23 with the average wage and price inflation of preceding years. The comparison scenarios were unmitigated cost of living increases, and mitigation by the UK Government’s Energy Price Guarantee (EPG) and Cost of Living Support payments.Main outcome measuresPremature mortality rate and life expectancy at birth by Scottish Index of Multiple Deprivation (SIMD) group, and inequalities in both.ResultsUnmitigated price inflation was 14.9% for the highest income group and 22.9% for the lowest. UK Government policies partially mitigated impacts of the rising cost of living on real incomes, although households in the most deprived areas of Scotland would still be £1,400 per year worse off than at baseline. With the mitigating measures in place, premature mortality was estimated to increase by up to 6.4%, and life expectancy to decrease by up to 0.9%. Effects would be greater in more deprived areas, and inequalities would increase as a result.ConclusionsLarge and inequitable impacts on mortality in Scotland are predicted if real-terms income reductions are sustained. Progressive Cost of Living Support payments are not sufficient to offset the mortality impacts of the greater real income reductions in deprived areas.What is already known on this topicOver the last decade, life expectancy in Scotland has stalled and inequalities have increased.Income reductions have been related to increased mortality risk, hence the economy matters for public health.The impacts of the rising cost of living and mitigating policies on mortality and inequalities require estimation to inform policymaking.What this study addsThe mortality impacts of inflation and real-terms income reduction are likely to be large and negative, with marked inequalities in how these are experienced.Current public policy responses are not sufficient to protect health and prevent widening inequalities.Bolder and more progressive policy responses are required if health is to improve and health inequalities are to narrow.
