The impact of the English national health inequalities strategy on inequalities in mortality at age 65: a time-trend analysis.

Abstract

During the 1997-2010 Labour government, several policies were implemented to narrow health inequalities as part of a national health inequalities strategy. Many of these policies are likely to have had a disproportionately large impact on people aged 65 and over. We aimed to understand the association between the health inequalities strategy period and inequalities in mortality at age 65-69. We use population at risk and mortality data covering 1991-2019 to calculate mortality rate at age 65-69 at the Local Authority level. We use the 2019 Index of Multiple Deprivation to examine geographical inequalities. We employ segmented linear regression models with marginal spline terms for the strategy period and interact these with an indicator of deprivation to understand how inequalities changed before, during and after the strategy. The reporting of this study adheres to STROBE guidelines. Mortality rates in each deprivation quintile improved continuously throughout the period of study. Prior to the programme (1991-9) there was no significant change in absolute inequalities. However, during the strategy (2000-10) there was a significant decrease in absolute inequalities of -9.66 (-17.48 to -1.84). The period following the strategy (2011-19) was associated with a significant increase in absolute inequalities of 12.84 (6.60 to 19.08). Our results were robust to a range of sensitivity tests. The English health inequalities strategy was associated with a significant reduction in absolute inequality in mortality age 65-69. Future strategies to address inequalities in ageing populations may benefit from adopting a similar approach.
