Scottish ‘excess’ mortality: comparing Glasgow with Liverpool and Manchester
This research programme involves a number of different projects, all aimed at gaining a better understanding of what lies behind the ‘excess’ levels of poor health (i.e. that which does not appear to be explained by socioeconomic deprivation alone) seen in Scotland and, in particular, Glasgow, compared to other parts of the UK.
The first stage explored the relationship between socioeconomic circumstances and mortality in Glasgow and its two most similar and comparable post-industrial UK cities: Liverpool and Manchester. This showed that while the deprivation profiles of the cities were almost identical, mortality in Glasgow was significantly higher (30% higher for premature deaths; 15% higher for deaths at all ages).
Following publication of this report, a separate piece of work in 2011 sought to summarise, and assess, the various explanations for Glasgow’s (and Scotland’s) poor health status.
A range of people were invited to comment on this synthesis report. The responses received have been collated into a short commentary report. The synthesis is currently being updated in the light of the considerable amount of subsequent research that has been undertaken, some of which is summarised below.
The second phase of research incorporates a number of different projects relating to the many hypotheses that have been proposed to explain Scotland’s and Glasgow’s high levels of excess mortality.
Qualitative research has been undertaken in a number of different communities in Glasgow, Liverpool and Manchester to explore potential reasons for the poorer levels of health seen across the whole Glasgow population in comparison to those in the English cities. A report will be published in 2015.
A population survey was undertaken in Glasgow, Liverpool and Manchester in 2011 in which new data were collected for some of the potential explanations that have been proposed in relation to Glasgow's excess mortality, and which were outlined in the 2011 synthesis report.
The survey collected new data on social capital, political engagement & perceptions, ‘sense of coherence’, optimism, different ‘individual values’ and more. Results from the analyses of the survey were published in June 2013 and a briefing paper is also available.
Spatial patterning of deprivation
The results of GCPH-funded analyses by Glasgow University of the differences in the patterning of deprivation in the three cities, and their potential impact on neighbourhood mortality rates, was published in April 2013. Download the report and related briefing paper.
Historical changes in deprivation and city structure
A PhD studentship is being funded by GCPH to explore the extent to which historical changes in deprivation and changes in city structure in Glasgow, Liverpool and Manchester may have impacted on health profiles. The PhD will run until 2015, and is based at the University of Glasgow. Further details are available here.
Early years research
Longitudinal cohort survey data (and other data sources) were used to assess the extent to which the early years experiences of residents of Glasgow, Liverpool and Manchester may have differed in recent decades. The results are published in a report, Poverty, parenting and poor health, as well as a related briefing paper.
Impact of local policy and practice
NHS Health Scotland is funding a PhD studentship at the University of the West of Scotland, examining policy and practice of local government in each of the three cities, and their potential impact on population health. The PhD is running from 2014 to 2017. Further details are available on request.
Detailed analyses of patterns and trends in alcohol consumption and harm in Scotland and England (with an additional focus on Glasgow, Liverpool and Manchester) have been undertaken. A journal article, ‘Alcohol-related mortality in deprived UK cities: worrying trends in young women challenge recent national downward trends’, was published in the Journal of Epidemiology and Community Health and a more detailed briefing paper (including results of additional analyses for other Scottish cities) is available.
Liverpool John Moores University is undertaking GCPH-funded research into the impact of problem drug use on Glasgow's excess mortality compared to Liverpool and Manchester. Results are expected in 2015.
A systematic review of the link between Vitamin D deficiency and all-cause mortality was undertaken in 2012. The results were published in July 2013 in BMC Public Health. Download the article.
Other projects and developments
A number of other research projects are either planned or are underway. These include a focus on the 'vulnerability' of cities and populations, an examination of the scale of urban change experienced in the cities, housing quality, the nature of employment, and more. We are currently, with NHS Health Scotland, working towards providing an updated synthesis of all the research undertaken, and its implications for our understanding of reasons for excess mortality in Scotland and Glasgow. This work will be completed by summer 2015. Further details are available from David Walsh.
