Coastal Health Outcomes – Contributing to the Chief Medical Officer’s Annual Report 2021

Research comparing coastal and non-coastal areas using the Quality Outcome Framework was used in the Chief Medical Officer's Report

Professor Sheena Asthana and Dr Alex Gibson contributed to the UK’s Chief Medical Officer’s 2021 Annual Report on ‘Health in Coastal Communities’. Their work, which compared coastal and non-coastal areas using the Quality Outcome Framework – found:
  • a higher burden of heart disease, diabetes, cancer, mental health and COPD in coastal areas,
  • age and deprivation are two causes of this but health service standards, indicators and emergency admissions may also play a part,
  • life expectancy is significantly lower in coastal areas,
  • lower participation in Higher Education, as well as higher rates of hospital admissions for young people with ‘health-risking behaviour’, show the effects of socio-psychological and economic dislocation in coastal communities.
Their findings also point to the lack of available data for small areas on or beyond the coastal fringe.
Researchers at the University of Plymouth have also found that digital inequity is an important part of this inequality and that three different types of digital equity exist:
  • digital connection: being able to access the same digital facilities and services as everyone else
  • digital employability: having an equal chance for jobs in the digital economy
  • digitally-enabled: using digital to have an equal chance of participating in aspects of society otherwise denied.
Researchers at the University of Plymouth, including Professor Ray Jones MBE and Professor Sheena Asthana – who contributed to the Chief Medical Officer's Report – and Professor Katharine Willis have been working to address these digital inequities and poor health outcomes in our coastal communities.

The burden of ill-health

Coastal communities appear to include a disproportionately high burden of ill health and this is demonstrated in the mapping of Coronary Heart Disease (CHD). Between 2014-2019, nearly 60,000 more people were on CHD registers in coastal areas (mapped by Lower Layer Super Output Areas or LSOAs) – or 17.8%.

Conditions including hypertension, stroke and transient ischemic attack (TIA), heart failure and peripheral arterial disease (PAD) show similar differences in prevalence between inland and coastal communities.

Age and deprivation go some way to explain this – both factors are associated with increased risk of diseases, higher prevalence of CHD and other cardiovascular diseases. Coastal residents are more likely to be older and live in a more deprived area. However, Professor Asthana and Dr Gibson found that these factors do not fully account for the difference – rates are still higher in deprived coastal areas compared to similarly deprived inland areas. Similarly, they also found that the ‘coastal effect’ is associated with ill-health that cannot be wholly explained by demography or ethnicity.

The ‘coastal effect’ in Primary Care

Professor Asthana and Dr Gibson’s research found lower recorded recommended treatment rates in coastal areas, in comparison to non-coastal areas. For example, 39.9% of Type 1 diabetes patients in coastal areas received at least eight of the recommended care processes for the condition, compared to 40.8% in non-coastal areas. This represents a marginally lower, but still significant difference.

Similarly, cancer conversion rates – the percentage of urgent suspected cancer referrals which result in a diagnosis of cancer – is 8.4% in coastal areas, compared to 7.4% in non-coastal areas. This difference could be a reflection of late presentations by older, more deprived populations but may also be because they face greater barriers to secondary treatment. Between 2015-2019 there were, on average, 2,127 patients per full-time equivalent (FTE) GP in coastal areas, compared to 2,079 in non-coastal areas. This is despite the fact coastal populations are older and more deprived.

It is concluded that there is a substantial health service deficit in coastal communities that is leading to a small, but significant ‘coastal effect’ of ill-health.


Life expectancy in coastal areas

Mortality rates categorised by Middle Layer Super Output Area (MSOA) demonstrate that deaths from all causes are, on average, 8.8% higher in coastal areas. Standardised mortality rates (SMRs) are higher in coastal areas for cancer, circulatory disease, stroke, respiratory disease and ‘preventable disease’ – a category that is defined as ‘causes where all or most deaths could potentially be prevented by public health interventions in the broadest sense'.

It is recognised that this could also be influenced by a greater proportion of people smoking in coastal areas, as well as higher rates of obesity and more ‘health-risking behaviours’ of coastal residents.

Living on the periphery

There are a number of reasons why coastal communities experience poorer than expected health outcomes – even when allowing for demography and deprivation. The labour market is one of them. The coastal labour force tends to work in sectors that are relatively low-skilled, low-paid and service-sector orientated.

The Office for National Statistics in 2020 demonstrated that nine of the 13 council areas with the lowest average weekly wages were in coastal areas – Boston, Rother, Blackpool, Great Yarmouth, North Devon, North Norfolk, Torbay, Cornwall and Kingston upon Hull.

Low pay and low job security reduce access to decent housing, healthy food and increase exposure to occupational hazards. Furthermore, these areas, that rely on tourism, have been hard hit by Covid-19.

The young’s health-risking behaviour

The effects of limited employment opportunities in coastal communities are likely to affect the development of children and young people. There is a significant disparity between coastal and non-coastal areas in terms of hospital admissions due to ‘health-risking behaviour’. For example, self-harm amongst 10-24-year-olds and due to drug/alcohol misuse for under18s is substantially higher in coastal areas.

Whilst negative outcomes are often associated with poor performance, children in coastal areas only perform slightly less well than elsewhere. What is more significant is the educational capital supporting children, and those who progress onto higher education. Coastal communities see a higher proportion of working-age adults without educational qualifications, and a low proportion of those achieving two A levels or equivalent.

Digital connection

Digital connection equity requires broadband and skills. The unconnected or poorly connected are mainly older people but also people with visual or hearing loss. Better design of digital services and community efforts to ensure availability is needed across the UK.

Digital employability

Inequalities in digital employability is part of the ‘levelling up’ agenda. In coastal regions such as Cornwall traditional industries such as farming, mining, fishing, and port activity have all declined, with alternative, often high-wage digital sectors struggling to emerge resulting in an exodus of younger skilled people.

Digital enablement

Many coastal regions like Cornwall have social, environmental and heritage assets. While access to such cultural and environmental assets are known to improve health and wellbeing, equitable access is not always available to older people. Digital enablement (e.g. through virtual reality walking) can reconnect housebound older people with their local culture and community groups. Involving younger people in intergenerational co-creation could help improve all three types of digital equity.
