Abstract
In response to the 2007/8 financial crisis and the subsequent ‘Great Recession’, the UK government pursued a policy of austerity, characterised by public spending cuts and reductions in working-age welfare benefits. This paper reports on a case study of the effects of this policy on local inequalities in mental health and wellbeing in the local authority of Stockton-on-Tees in the North East of England, an area with very high spatial and socio-economic inequalities. Follow-up findings from a prospective cohort study of the gap in mental health and wellbeing between the most and least deprived neighbourhoods of Stockton-on-Tees is presented. It is the first quantitative study to use primary data to intensively and longitudinally explore local inequalities in mental health and wellbeing during austerity and it also examines any changes in the underpinning social and behavioural determinants of health. Using a stratified random sampling technique, the data was analysed using linear mixed effects model (LMM) that explored any changes in the gap in mental health and wellbeing between people from the most and least deprived areas, alongside any changes in the material, psychosocial and behavioural determinants. The main findings are that the significant gap in mental health between the two areas remained constant over the 18-month study period, whilst there were no changes in the underlying determinants. These results may reflect our relatively short follow-up period or the fact that the cohort sample were older than the general population and pensioners in the UK have largely been protected from austerity. The study therefore potentially provides further empirical evidence to support assertions that social safety nets matter - particularly in times of economic upheaval.

1. Background
In response to the 2007/8 financial crisis and the subsequent ‘Great Recession’, the UK government pursued a policy of austerity, characterised by public spending cuts and reductions in working-age welfare benefits. This paper reports on a case study of the effects of this policy on local inequalities in mental health and wellbeing in the local authority of Stockton-on-Tees in the North East of England, an area with very high spatial and socio-economic inequalities. This paper presents follow-up findings from a prospective cohort study of the gap in mental health and wellbeing between the most and least deprived neighbourhoods of Stockton-on-Tees. It is the first quantitative study to use primary data to intensively and longitudinally explore local inequalities in mental health and wellbeing during austerity and it also examines any changes in the underpinning social and behavioural determinants of health – the pathways potentially linking austerity with health inequalities.
1.1. ‘Great Recession’ and Austerity
The global financial crisis of 2007/8 led to a long period of recession across Europe. The catalyst for the slump was a downturn in the USA housing market which led to a massive collapse in financial markets across the world. Banks increasingly required state bailouts, stock markets posted massive falls which continued as the effects in the ‘real’ economy began to be felt with high unemployment rates of around 8.5% in the UK and the USA, 10–12% in France and Italy and more than 20% in Spain and Greece. The IMF announced that the global economy was experiencing its worst period for 60 years: the ‘Great Recession’ (Gamble, 2009). Government responses to the recession varied, in the UK (like a number of other countries most notably Spain or Greece), a strict policy of austerity was implemented from 2010 onwards (Kitson, Martin, & Tyler, 2011). This has been characterised by a drive to reduce public deficits via large scale cuts to central and local government budgets, reduced funding for the health care system, and large reductions in welfare services and working-age social security benefits. In a comparative European study, Reeves, Basu, McKee, Marmot, and Stuckler (2013) found that the UK austerity policy was the third most extensive.
It is estimated that the UK welfare reforms enacted up to 2015 will take nearly £19bn a year out of the economy. This is equivalent to around £470 a year for every adult of working age in the country. The biggest financial losses arise from reforms to incapacity-related benefits (£4.3bn a year), changes to Tax Credits (£3.6bn a year) and the cap of 1 percent up-rating of most working-age benefits (£3.4bn a year) (Beatty & Fothergill, 2014). The 2010–2015 Housing Benefit reforms resulted in more modest losses – an estimated £490 m a year arising from the under occupancy charge (most commonly referred to as ‘bedroom tax’), for example – but for the households affected the sums are nevertheless still large (e.g. £12 per week reductions per ‘spare room’ for those on benefits that are only around £65 per week) (Moffatt et al., 2016) (for more details see Bambra and Garthwaite, 2015, Bambra et al., 2015). Research shows that these welfare cuts – alongside the steep reductions in local government budgets of up to 40% - have hit the poorest parts of the country the hardest (Beatty & Fothergill, 2016): austerity has disproportionately impacted on the availability of key services in these areas, widening social inequalities within them and spatial inequalities between them and other areas (Pearce, 2013; Bambra and Garthwaite, 2015, Bambra et al., 2015, Schrecker and Bambra, 2015). These ‘reforms’ have also disproportionately impacted on low income households of working-age (Browne & Levell, 2010) whilst, in contrast, pensioner households have been more protected by, for example, the universal state pension ‘Triple Lock’ (a guarantee to increase the state pension every year by the higher of: inflation, average earnings or a minimum of 2.5%) and other universal allowances for the elderly such as the winter fuel allowance (Green et al., 2017).
1.2. Health inequalities
It is well documented that there are significant inequalities in health by socio-economic status. For example, in England, men and women living in the most deprived neighbourhoods have a life expectancy of 9 and 7 years less respectively than those living in the least deprived (ONS, 2014). There are similarly stark inequalities in mental health with, for example, suicide and self-harm rates considerably higher in the most deprived neighbourhoods (Cairns, Graham, & Bambra, 2017). Baseline analysis of the Stockton-on-Tess cohort also found a significant gap in mental health and wellbeing between the most and least deprived areas (Bambra, 2011, Beckfield and Bambra, 2016, Mattheys et al., 2016, Farrants et al., 2016).
These health inequalities are intimately linked to broader social and economic inequalities and so a widening of inequality, as a result of austerity, may lead to a further exacerbation of social and spatial health inequalities. There are three main pathways linking socio-economic status and health: materialist, psychosocial, and behavioural/cultural (Bartley, 2016, Skalická et al., 2009). The materialist explanation focuses on income and on what income enables – access to goods and services and exposures to material (physical) risk factors (e.g. poor housing, inadequate diet, physical hazards at work, environmental exposures). Cohort studies have linked poorer mental health with poverty, unemployment, and low income (Bartley, 2016). Psychosocial explanations focus on how social inequality makes people feel – domination/subordination, superiority/inferiority, social support, demands and control – and the effects of the biological consequences of these feelings on health. Cohort studies have shown that over time stress has an impact on the body, leading to physical and mental ill-health (Marmot & Wilkinson, 2005). The behavioural explanation considers the association between socio-economic status and health to be a result of health-related behaviours as a result of adverse personal/psychological characteristics or because unhealthy behaviours may be more culturally acceptable amongst lower socio-economic groups (Bartley, 2016, Skalická et al., 2009). Consumption of high amounts of alcohol appears to be a particular risk factor for mental ill health – whilst other behavioural factors such as smoking have a more nuanced relationship (WHO and Calouste Foundation 2014). The baseline analysis of the Stockton-on-Tess cohort found material and psychosocial factors to be the most important determinants of inequalities in mental health (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016).
1.3. Recession, austerity and health
The short term overall population health effects of recessions are rather mixed with the majority of international studies concluding that all-cause mortality, deaths from cardiovascular disease and from motor vehicle accidents and hazardous health behaviours decrease during economic downturns, whilst deaths from suicides, rates of mental ill health and chronic illnesses increase (Bambra, 2011). Following the 2007/8 crisis, worldwide an excess of 4884 suicides were observed in 2009 (Corcoran, Griffin, Arensman, Fitzgerald, & Perry, 2015) and over the next 3 years (2008–2010) an excess of 4750 suicides occurred in the USA, 1000 suicides in England, and 680 suicides in Spain. Areas of the UK with higher unemployment rates had greater increases in suicide rates (Hawton, Bergen, & Geulayov, 2016). There is also evidence of other increases in poor mental health and wellbeing after the ‘Great Recession’ including self-harm and psychiatric morbidity (Barnes et al., 2017, Vizard and Obolenskaya, 2015).
However, the effects of recessions on health and health inequalities vary by country – with more negative trends in mental health and wellbeing in those countries, including the UK, that implemented austerity (Stuckler and Basu, 2013, Basu et al., 2017). Following the 2008 recession, Greece, Italy and Spain imposed cuts in health and social protection budgets. These countries experienced worse health effects when compared to countries such as Germany, Iceland and Sweden who opted to maintain social safety nets over austerity (Stuckler and Basu, 2013, Helliwell et al., 2017). Similarly, Karanikolos et al. (2013) found that across Europe, weak social protection systems increased the health and social crisis in Europe. Whilst there are few quantitative studies of the effects of austerity on health inequalities in the UK or elsewhere, initial studies such as that by Barr, Kinderman, and Whitehead (2015a) suggest that inequalities in mental health and wellbeing increased at a higher rate between 2009 and 2013. Further, people living in more deprived areas have seen the largest increases in poor mental health (Barr et al., 2015b) and self-harm (Barnes et al., 2016). Internationally, Niedzwiedz, Mitchell, Shortt, and Pearce (2016) found that reductions in spending levels or increased conditionality may have adversely effected the mental health of disadvantaged social groups. These are in keeping with previous studies of the effects of public sector and welfare state contractions on increases in health inequalities in the UK, Finland, US and New Zealand in the 1980s and 1990s (Bambra, 2016; Bambra et al., 2015; Copeland et al., 2015, Kokkinen et al., 2015; Farrants et al., 2016).
The existing research literature therefore suggests: (1) health inequalities are linked to social inequalities; (2) the importance of social safety nets in mitigating health inequalities – particularly during economic downturns; and (3) that austerity is potentially increasing health inequalities by increasing social inequalities (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016). It is in this context that this paper reports on a case study of a cohort survey of the effects of austerity on local inequalities in mental health and wellbeing in the local authority of Stockton-on-Tees in the North East of England. It examines if there are any changes in the gap in mental health between the least and most deprived areas during a period of austerity and if there are any changes in the underlying social and behavioural determinants.
2. Methods
As part of the ‘Local Health Inequalities in an Age of Austerity: The Stockton-on-Tees Study’, this paper presents the follow-up findings from a prospective 18-month cohort survey of mental health and wellbeing and the social and behavioural determinants of health, in the most and least deprived areas of the local authority. Stockton-on-Tees in the North East of England was chosen as the study site because it has the highest spatial health inequalities in England both for men (at a 17.3 year difference in life expectancy at birth between lower super output areas - LSOAs) and for women (11.4 year gap in life expectancy) (Public Health England, 2015). This makes it a particularly important site to analyse health inequalities during austerity. Stockton-on-Tees has a population of 191,600 residents (ONS, 2013). The population is overwhelmingly White (93.4%) although there is a small Asian/Asian British population (Indian 0.8%, Pakistani 1.6%, Bangladeshi 0.1%, Chinese 0.5%) (ONS, 2013). Stockton has high levels of social inequality, with some areas of the local authority with very low levels of deprivation (e.g. Ingleby Barwick) and others with high levels of deprivation (e.g. Town Centre). These areas are often in close proximity to one another. Deprivation overall is higher than the national average e.g. 21.9% of children live in poverty compared to 19.2% nationally (Public Health England, 2015).
2.1. Sampling and data collection
The baseline analysis and full details of the sampling technique are contained in Mattheys et al. (2016). The survey used a random baseline sample of adults aged over 18, split between participants from the 20 most and 20 least deprived LSOAs of Stockton-on-Tees (derived using 2010 Index of Multiple Deprivation [IMD] scores for England). These are shown in Fig. 1. LSOAs are small areas – ‘neighbourhoods’ - of relatively even size, with around 1500 people in each area; there are 32,484 LSOAs in England (Dept for Communities and Local Government, 2011). The IMD is a composite indicator that uses 38 separate indicators under seven distinct domains (Income, Employment, Health and Disability, Education Skills and Training, Barriers to Housing and Other Services, Crime and Living Environment). The IMD provides an overall score by drawing together weighted scores from each of these domains. The scores for each LSOA are then ranked so that there is a relative deprivation score for each LSOA in England, allowing different LSOAs to be compared (Dept for Communities and Local Government, 2011). It is the key measure to identify area level deprivation and its concentration in geographical units lower than local authorities in England (Payne and Abel, 2012, Noble et al., 2006). Multistage sampling was used whereby 40 LSOAs were first grouped into the 20 most and 20 least deprived (IMD range 1.54–74.5). Within each group, a random sample of households (addresses) were selected and a single participant per household was determined using a household selection grid to ensure even distribution of age and gender (De Vaus, 1991).

20,013 eligible addresses and phone numbers were identified from the forty selected LSOAs, using the most recent Office for National Statistics (ONS) postcode lookup tables. The amount of eligible addresses ranged from 313 to 1380 addresses per LSOA. To meet the targeted number of 800 participants, 200 target households were randomly sampled in each of the 40 LSOAs assuming 90% non-response rate. The assumption of a 10% enrolment rate was because the survey used a postal initial recruitment approach and so response was expected to be lower than for other recruitment methods (Eriksen et al., 2011, Sinclair et al., 2012). A total of 8000 households (4000 each from the most and least deprived LSOAs) were sent study invitation letters to obtain consent to participate in the study based on opt-in consenting approach. Participants were then surveyed four times over 18-months: April 2014 (baseline, wave 1, face-to-face), October 2014 (wave 2, telephone), April 2015 (wave 3, telephone) and October 2015 (wave 4, telephone). Only 2318 of the 8000 were contactable and a total of 836 participants completed the face-to-face baseline survey: 397 in the most deprived areas and 439 in the least deprived areas. This is a baseline response of 10% or 36% of contacted households (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016). Attrition reduced the final wave 4 sample size to 310: 176 in the most deprived areas and 134 in the least deprived areas. This was only a 37% overall follow up rate but it fell within our original conservative power calculation (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016). Full ethics was granted by University ethics committee.
2.2. Outcome and explanatory measures
The questionnaires included questions on mental health, physical health, demographics and the social and behavioural determinants of health - reflecting the well-known theories of health inequalities. The main outcomes in this analysis are validated instruments of mental health: Warwick Edinburgh Mental Well Being Scale (WEMWBS) and the SF8. The primary explanatory variable is area-level deprivation (“Deprivation”), which takes value of 1 if a participant was from one of the twenty most deprived LSOAs and 0 if the participant was from one of the twenty least deprived LSOAs. Age and gender were used as controlled variables in the models, except where they were pre-defined. Other explanatory variables used included material factors (including measures of the physical environment [damp home, dark home, home is not warm enough in winter, problems with neighbourhood noise, problem with pollution and problems with crimes], educational status, housing tenure, household receipt of benefits, employment and household annual income), psychosocial factors (neighbourhood safety perception, lack of companionship, feeling left out and feeling isolated), and behavioural factors (smoking, alcohol consumption and physical exercise).
2.3. Statistical analysis
Descriptive analysis of the longitudinal data was done using summary statistics and visualisation aids. Continuous data were summarised using MEAN±SD, while the categorical variables were summarised using frequencies and percentages. The outcomes were analysed using linear mixed effects model (LMM) to account for correlation between the repeated observations per participant. All the analyses presented in this paper treated survey waves as a categorical variable and only random intercept is used in the linear mixed effect to capture intra-individual correlation. LMMs were fitted for the mental health outcomes with only the deprivation indicator and the waves as the predictor variables. Thereafter, an adjusted model was fitted for the association between mental health outcomes and the deprivation indicator by first including each of the explanatory covariates to the initial model and using likelihood ratio test statistics to test whether given the deprivation inequalities, the explanatory variable explains any residual variance in the mental health outcomes. This approach is similar to the univariate model building technique (Hosmer et al., 2013, Agresti, 2015), except that deprivation, age and gender and survey waves are included in each model in addition to each explanatory variable. The final most parsimonious model was obtained by combining all explanatory variables with either significant change over time or significant association with deprivation indicators. Likelihood ratio test was then used to remove redundant explanatory variable without substantial loss of information (Verbeke & Molenberghs, 2000).
2.4. Sensitivity analyses
The survey participants are older than the general population and there is a higher representation of women (Bhandari, Kasim, Warren, Akhter, & Bambra, 2017; Mattheys et al., 2016). There is also considerable attrition over the four waves. So, even though the analysis adjusts for age and gender, a post-stratification weighting scheme was devised and a sensitivity analysis was conducted using this weighted data (Lynn, 1996, Copas and Farewell, 1998, Spiess, 2005). A further challenge in the survey was item non-response where there were intermittent missing data in the explanatory variables. Additional analysis based on imputed data was therefore also conducted with each of the mental health outcomes and explanatory variables individually imputed, conditional on their baseline data, age and gender using the Markov Chain Monte Carlo (MCMC) method. The methods for the weighted LMM and MI are presented in Web Appendix 1.
3. Results
3.1. Demographic characteristics
Table 1 shows the demographic characteristics of the cohort by wave and deprivation. At baseline, 27.5% of the participants in the most-deprived areas were aged 65 years or over, whilst 32.8% were in the least-deprived areas. In the later waves, the percentages of older participants tended to increase to 38.1% in the most deprived and 46.2% in the least deprived areas by wave 4. There were more women than men participating in the study – although this did not increase substantially over the four waves: from 57% to 59% in the most deprived areas and from 59% to 61% for the least deprived. Throughout the study, the proportions of single participants were much higher in the most deprived areas (35% to 39%) compared to the least deprived areas (11–17%).

3.2. Inequalities in mental health and wellbeing
Table 2 provides the mental health scores for SF8MCS and WEMWBS by deprivation level for each wave. The average change in both mental health outcomes are also plotted overtime in Fig. 2. These show that the average SF8MCS and WEMWBS scores for both the most and least deprived areas do not increase significantly or linearly over time and there is no increase in the mental health gap between the two types of areas over the four waves. The significant inequalities in mental health scores between the least and most deprived areas detected at baseline (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016) did not change over the following 18 months.

The results from the LMMs are presented in Table 3. In keeping with the visualisation of the average scores in Fig. 2, the results show that the gap in mental health and wellbeing did not change during the 18-month study period. The average difference between the most and least deprived areas for both the SF8MCS and WEMWBS at Wave 1 are not statistically different from the mean difference between the most and least deprived areas at Wave 2 (effect estimates: SF8MCS -0.45; -2.05, 1.14; WEMWBS -0.21, -1.85, 1.43), Wave 3 (SF8MCS -0.18; -1.90, 1.53; WEMWBS -1.12, -3.71, 1.48) or Wave 4 (SF8MCS -0.50; -2.36, 1.36; WEMWBS -0.87, -1.16, 2.90). In general, the average mental health and wellbeing scores are constant over the study period in both the most and least deprived areas. However, the results show that people living in the most deprived areas have statistically significantly lower mental health and wellbeing scores than those living in the least deprived areas across all waves. Sensitively analyses of the data applying weights (weighted LMM) and multiple imputations (MI) resulted in similar findings as analysing the data without weighting (LMM).

3.3. Material, psychosocial and behavioural factors
Table 4, Table 5, Table 6 show the material, psychosocial and behavioural factors by wave and deprivation. Table 4 shows very large differences at all waves in material factors between people living in the most and the least deprived areas in terms of the majority of social, economic and physical environment variables. Differences in terms of benefit receipt and a warm house were smaller though – perhaps because pensions are a universal benefit and an additional winter fuel allowance is also provided to all pensioners. Table 5 shows similarly large and constant differences across waves in the psychosocial factors – these were largely better in the least deprived areas than the most deprived with the exception of having a social meeting everyday which was more common in the most deprived areas but average happiness score remained roughly 0.4–0.5 lower than those living in least deprived areas. In terms of the behavioural factors, Table 6 shows that alcohol consumption was much lower and daily exercise (which included walking) was a little higher amongst participants in the most deprived areas. On average, fruit and vegetable consumption was one portion per day higher in the least deprived areas whilst smoking was more than 20 percentage points higher in the most deprived areas. These behavioural patterns remained fairly static across the four waves.

A parsimonious LMM was fitted for each of the mental health outcomes to see if there were any changes over time in the associations with material, psychosocial and behavioural factors. A likelihood ratio test was used to remove redundant factors without significant loss of information. The most parsimonious model for SF8MCS and WEMWBS are respectively presented in Table 7, Table 8. These show firstly that a significant difference in mental health and wellbeing between the most and least deprived areas at each wave remained even after adjusting for the material, psychosocial and behavioural explanatory factors. However, again, there was still no significant change in the size of the area gaps in SF8MCS and WEMWBS. Secondly, there were also no significant changes in which factors were most associated with the mental health outcomes. In keeping with our baseline results, material and psychosocial factors remained the most significant (Bambra, 2011, Bambra et al., 2015, Beckfield and Bambra, 2016, Mattheys et al., 2016). Participants who lived in accommodation with at least one dark room, those who more often felt lack of companion, felt left out and felt isolated had worse SF8MCS scores than those with no dark room or who hardly left lack of companionship, left out or isolated. Happiness, being in employment and alcohol use remained positively associated with SF8MCS scores. The happier a participant was, the better is their SF8MCS score and those in employment had better mental health score than those unemployed. The results from the analysis of WEMWBS are consistent with the results from SF8MCS. Additionally, participants who felt very safe whilst walking in the neighbourhood had better WEMWBS score than those who felt unsafe. Those who regularly do physical activity also had better WEMWBS scores than those that rarely do exercise; and smokers had worst scores than non-smokers.

4. Discussion
This study set out to longitudinally explore local inequalities in mental health and wellbeing during austerity and to examine any changes in the social and behavioural pathways potentially linking austerity with health. It has found a large mental health gap between the least and most deprived neighbourhoods of the case study site, Stockton on Tees - but no change in the gap over time. It also found no changes in terms of the social and behavioural determinants of health – the pathways linking austerity and mental health. These findings are in contrast to other research - both in the UK and internationally - into the health impacts of austerity and associated welfare reform and public service budget reductions. For example, Barr et al. (2015a) suggest that geographical inequalities in mental health and wellbeing in the UK increased after austerity and that people living in more deprived areas experienced a larger increase in poor mental health (Barr et al., 2015b) and self-harm (Barnes et al., 2016). Similarly, qualitative research with people with existing mental health conditions also found that austerity exacerbated their situation (Mattheys, Warren, & Bambra, 2018). Internationally, Karanikolos et al. (2013), Stuckler and Basu (2013), Niedzwiedz et al. (2016) and Helliwell et al., (2017) also found that weakened social protection systems adversely effected mental health in Europe, particularly amongst the most disadvantaged social groups.
There are several potential explanations for the differences between the results presented in this paper and the wider literature. Firstly, this study found no changes in the underpinning pathways. Using the social determinants of health framework, a change in mental health would need to be precipitated by a change in the social conditions in which people are living or their health behaviours (Smith, Hill, & Bambra, 2016). On this basis then, it is not surprising that no change in the mental health gap was detected in the survey as there was no change in the underlying causal pathways. Further, there was already a big mental health gap at baseline and people in the most deprived neighbourhoods were already living in very difficult circumstances so there may not have been much further potential for deterioration.
Secondly, the follow-up length and timing of the study might also be factors behind our potentially anomalous findings. The survey only had an 18-month follow-up and, whilst mental health is a fairly responsive and sensitive indicator, this still might not have been long enough to detect changes either in the underpinning pathways or the mental health outcomes themselves. For example, this means that there was little time for any significant changes in area characteristics to occur or to impact on health outcomes (Norman, 2018). Further, the timing of the baseline survey (in 2014) was in a period after the economic recession and after some austerity measures had already been implemented (Bambra & Garthwaite, 2015). Indeed, by way of example, the unemployment rate in Stockton on Tees peaked in 2013 and then rapidly improved, returning to pre-recession levels by 2016 (Public Health England, 2017). In terms of austerity measures, the Household Benefit Cap, the Under Occupancy Charge (better known as the ‘bedroom tax’, and various other welfare restrictions were all introduced by 2013 (for an austerity timeline see Mattheys et al., 2016, Farrants et al., 2016 and Bambra (2016). This means that an austerity- or recession-related deterioration in mental health - as expected by the wider literature - may have already occurred before the baseline was conducted. Our original intention was to have a longer follow-up period but the high-level of attrition meant that in order to maintain power, we had to prematurely end data collection.
Thirdly, the nature of the survey sample may also be an issue. We focused on the two extremes - the most and least deprived neighbourhoods. This means that we may have missed any impacts on mental health of those in the middle of the socio-spatial gradient (the so called ‘squeezed middle’) such as people who lost access to working tax credits or child benefit payments suffered unemployment wage reductions. Participants in both types of neighbourhood were also generally older than the general population of Stockton on Tees. This is potentially significant as austerity measures particularly with regards to welfare reform, were targeted at working age people as well as children. Pensioners were largely protected (with the exception of reductions in social care which impacted most on the very old >85 years, Hiam, Dorling, Harrison, & McKee, 2017). Most notably, the universal state pension and other universal allowances for the elderly such as the winter fuel allowance (Green et al., 2017) were either left untouched during austerity or were enhanced (e.g. the pensions ‘Triple Lock’) whilst working age and child related benefits were cut (Green et al., 2017). Arguably then, the survey findings presented in this paper are actually in keeping with the wider literature as the fact that the gap in mental health amongst an older group did not change over time potentially shows the importance of maintaining social safety nets. This is in keeping with other studies of the importance of pensions for health and health inequalities including pan-European research by Lundberg et al. (2008) who found that increased expenditure on pensions improved older age mortality; Bambra and Garthwaite, 2015, Bambra et al., 2015, Schrecker and Bambra, 2015 who highlighted the importance of pensions for post-65 life expectancy; and Copeland et al. who noted the importance of social safety nets for stabilising health inequalities during times of recession.
5. Limitations
The study is subject to a number of important limitations. The baseline sample size was moderate (although within power calculations) and the response rate was low with only c36% of contacted households (and only c10% of all of our 8000 sampling frame) participating in the survey. The survey also experienced high attrition with only 37% in the final wave (Bhandari et al., 2017). This may undermine the representativeness of the cohort sample and indeed, older people and women were over represented compared to the general population. Whilst models were adjusted and a weighted sensitivity analysis was conducted - these factors may still effect the generalisability of the findings. There is also the strong possibility of a ‘healthy responder effect’, whereby people with health problems are less likely to respond to research requests. This may also have resulted in selective recruitment and attrition rates. Sensitivity analysis using multiple imputation was used but the findings should still be interpreted with a certain amount of caution. The survey sample was though a static population with evidence of ageing in place – perhaps a side-effect of being an older sample (Norman, 2018). The survey also relies on self-reported health measures which may have limited precision and reliability (although there is a strong association between self-reported health and more objective outcomes including mortality, see Norman and Bambra (2007)). Finally, this study relates only to just one place – Stockton-on-Tees. This local authority has the highest gap in life expectancy between people the most and least deprived areas in the whole of England and the results may not be generalisable to other places.
6. Conclusion
This study makes an important contribution to the ongoing international scholarly debate about the effects of austerity on geographical inequalities in health. Using a detailed longitudinal survey of a random stratified sample of individuals living in the most and least deprived neighbourhoods of Stockton on Tees, it found a significant mental health gap but no changes in this gap over an 18-month period in which the UK experienced austerity. The age distribution of the sample may be an important factor behind why there were no changes in inequalities in mental health detected, as older people were largely exempted from welfare reform. The study therefore potentially provides further empirical evidence to support assertions that social safety nets matter particularly in times of economic upheaval. However, study limitations mean that the findings should be interpreted with some caution.
