2. Achieving good health for all: where are we now?

 

Key points

  • Since 2010/11, there has been an unprecedented reversal of life expectancy in some groups, indicating that continuing improvements in health cannot be taken for granted.
  • People born in the most deprived 10% of local areas are expected to live over 18 fewer years in good health than those born in the least deprived 10% of local areas.
  • Internationally, the UK ranks 22 out of 38 OECD countries for life expectancy.
  • There is a shift in the pattern of ill health towards multiple health conditions. In 2006/07, one in ten patients admitted to hospital as an emergency had over five conditions. In 2015/16, the figure was one in three.

2.1 Closing the gap in health inequalities

Life expectancy improvements have slowed

In the post-war period, the UK saw life expectancy increase by an average of about one year over every five years (a 12.5-year increase over 60 years since 1950) but this has slowed dramatically in recent years. In Wales and Scotland, life expectancy has started to decline. Across the UK as a whole, life expectancy trends vary by a person’s level of deprivation and sex, with certain regions and groups particularly badly affected.

A recent Public Health England review of trends in mortality in England found that, rather than being attributable to any single cause, the slowdown in improvement is likely to be the result of a number of factors operating simultaneously across a wide range of age groups, geographies and causes of death.

The Health Foundation has commissioned analysis to provide a more detailed understanding of the causes of the recent stalling of improvements in mortality and life expectancy in the UK. This work will present a more detailed picture of what is happening to mortality and life expectancy patterns across different population subgroups, and the multiple complex drivers at play. Figure 1 shows that, since 2011/13, female life expectancy at birth in England has started to decline for girls born in the most deprived 10% of local areas, while it has continued to improve for those born in the least deprived 10%. Life expectancy improvements for boys born in the most deprived 10% of local areas also appear to have been outstripped by boys born in the least deprived 10% over the same period. This reversal of life expectancy in some groups is unprecedented in modern times and indicates that continuing improvements in health cannot be taken for granted.

Inequalities in healthy life expectancy are widening

In addition to the inequality in life expectancy across local areas, there are far greater inequalities in healthy life expectancy (the number of years lived in self-assessed good health). People born in the most deprived 10% of local areas are expected to live over 18 fewer years in good health than those born in the least deprived 10% of local areas. The data for women are shown in Figure 2.

This means that not only can those born in more deprived areas expect a shorter overall life span, they can also expect a greater share of their life to be spent in poor health and a longer absolute number of years in poor health. For example, women living in the most deprived 10% of areas have a healthy life expectancy of just 52, but a life expectancy of 78.7, meaning they can expect to have nearly 27 years of poor health towards the end of their lives.

This difference in healthy life expectancy shows the scope for improvement in health across the population and the additional healthy life years that could be gained. However, in the context of current trends, improving these measures of health will be tough. For example, healthy life expectancy at birth for males in England increased by only 0.4 years between 2009–11 and 2015–17. If that rate of improvement continued to 2035, healthy life expectancy would have risen by only a further 1.1 years. Therefore, for men, it would take 75 years to complete the stated aim of the government’s Ageing Society Grand Challenge (as set out in the Industrial Strategy) to ‘ensure that people can enjoy at least five extra healthy, independent years of life by 2035, while narrowing the gap between the experience of the richest and poorest’. For women, where healthy life expectancy has slightly fallen in the last six years, there is an even greater challenge in meeting this goal.

International comparisons

Comparing the UK to other countries provides some indication of the potential scope for improvement. Internationally, the UK ranks 22 out of 38 OECD countries for life expectancy; Japan is the leader at 84.1 years compared to 81.2 for the UK.

The UK also has one of the biggest health gaps between the most and least deprived people compared to many other developed countries across the world. As shown in Figure 3, the share of the UK population in good health is 24% lower in the lowest income bracket than in the highest. In contrast, within the top-performing countries such as New Zealand, Greece and France, there is a gap of only 5–10% between the lowest and highest socioeconomic groups. Together, this highlights the significant room for improvement in outcomes in the UK in both an absolute sense and from the perspective of inequality.

Local comparisons

There are large differences in health, not only between areas with different deprivation levels, but also between areas with similar levels of deprivation.

Closing the inequalities gap will improve individual outcomes as well as the national position. Such a large change may feel extremely challenging. However, looking at variation within deciles shows that some areas with high levels of deprivation are already performing well. Figure 4 shows that, even within the most deprived deciles, there is a considerable variation in health. For instance, if health outcomes across the most deprived half of the population matched those in the middle of the distribution, there would be an average 3-year improvement in healthy life expectancy across the whole birth cohort.

Understanding the causes and drivers of the wide variations that exist in healthy life expectancy within areas of similarly ranked deprivation would provide useful insights into how to improve health outcomes. This will be the focus of future work at the Health Foundation.

Trends in more specific measures of public health outcomes provide important indications of where a major shift towards a preventative approach is needed most (trends in specific disease outcomes have been set out in the 2018 Global Burden of Disease study).

In considering the challenges facing government, attention needs to be paid to:

  • the growing needs of people with multiple health conditions
  • key prevention service indicators
  • risk factors for poor health.

Addressing the trends in these different types of health outcomes will require action at different levels (from individual to societal) and strategies that operate on different time horizons (from short to long term).

The growing needs of people with multiple health conditions

There is a shift in the pattern of ill health towards multiple health conditions. In 2006/07, one in ten patients admitted to hospital as an emergency had over five conditions.

In 2015/16, the figure was one in three. Meeting the growing needs of people with multiple health conditions is also a particular challenge in the most disadvantaged areas. Recent research undertaken by the Health Foundation found that, in the least deprived fifth of areas, people can expect to have more than two conditions by the time they are 71 years old, yet in the most deprived fifth, people reach the same level of illness a decade earlier, at 61 years of age.

As the number of people with multiple health conditions grows, the NHS will need to implement more effective secondary and tertiary prevention strategies that prevent disease progression and the harm done by long-term conditions. For example, there are still significant improvements to be made in areas such as cancer diagnosis. While there is a positive trend towards improvements in cancer survival rates overall, many cancers are still diagnosed at a late stage, with almost half of all lung cancers diagnosed at the most advanced stage.

Trends in prevention service indicators

While some prevention services have shown improvements in outcomes in recent years, there are worrying signs in others.

Despite drug misuse death and alcohol-specific deaths rates having increased over the last five years as shown by Figure 5, the number of people receiving treatment for drug and alcohol misuse is down 11% since the high point in 2013/14. The success rate of treatment has also been falling: it is now five percentage points lower than it was in 2013/14.

Other areas of concern identified by analysis from QualityWatch were:

  • The proportion of pregnant women who smoked at delivery fell 5% in the decade to 2016/17 but has plateaued since.
  • After large improvements in the early 2000s, the proportion of HIV cases diagnosed at a late stage of infection, when significant health damage may already have occurred and the infection may have been transmitted to others, increased by 3% between 2015 and 2017.
  • Coverage for all childhood vaccines has declined since 2013/14, and all but one are below the World Health Organization’s 95% coverage target.

Trends in risk factors for ill health

The decline in the prevalence of smoking in recent years has been a major success in the fields of public health and prevention. However, levels of obesity remain stubbornly high. This has implications for people’s overall wellbeing and long-term health and will have significant implications for future health and health service use. Obesity remains one of the country’s greatest public health challenges, with 29% of adults obese in 2017, up from 18% in 1997. In children, 20% were obese at age 10–11 in 2017/18, an increase of 1.7 percentage points compared with 10 years previously. More worrying still is that growth in child obesity has been driven by increasing rates of obesity among the most deprived 10% of children, as shown in Figure 6.

Loneliness is increasingly recognised as a risk factor for poor health. Although loneliness can be experienced at any age, it is particularly common in older people. While the proportion of people aged over 50 in England who say they are often lonely has remained similar over the last 10 years, population ageing means that the numbers experiencing it are increasing. If current trends continue, it is estimated that 2 million people aged over 50 will feel lonely by 2026, up from 1.4 million in 2016. This has major implications for health service use. Health Foundation analysis has found that people aged 65 and older who live alone are 50% more likely to go to A&E than those who live with someone else. They are also at increased risk of being admitted to hospital as an inpatient.

Young people’s mental health is another area of concern, with the latest data showing that 11.2% of 5- to 15-year olds report having at least one mental health disorder in 2017, up from 9.7% in 1999. This rise has been driven by increased rates of emotional disorders, particularly anxiety and depression. Emotional disorders are particularly common in teenagers, with 14.9% of 11- to 16-year olds affected.

One of the most fundamental drivers of good health is having an adequate income. An area of particular concern is the number of children experiencing poverty. Projections discussed in Section 5 (Figure 10) indicate that child poverty could rise from 30% in 2017/18 to a record high of 35% in 2023/24. Much of this is likely to be within working households. The child poverty rate for working households averaged 20% between 1996/97 and 2013/14, but is projected to increase to 29% by 2023/24. All of this suggests that, without policy action, a growing number of children will experience health-damaging poverty.

2.3 Creating the conditions for good health across the life course

Improving the length of time people live in good health has rightly been the focus of much recent policy debate. In 2018, for example, the government set out a mission, as part of the Ageing Society Grand Challenge in the Industrial Strategy to, ‘ensure that people can enjoy at least five extra healthy, independent years of life by 2035, while narrowing the gap between the experience of the richest and poorest’.

Recent trends show how big a challenge this will be. Healthy life expectancy at birth for males in England increased by only 0.4 years between 2009–11 and 2015–17. If that rate of improvement continued to 2035, healthy life expectancy would have risen by only a further 1.1 years, meaning it would take 75 years for the mission to be completed. For women, healthy life expectancy has actually slightly fallen in the last six years.

In aiming to improve health, it is important to consider that health-state life expectancies, which are effectively averages across the life course, tend to be discussed as though years spent in poor health always occur at older ages. However, that is not necessarily the case. Periods of poor health can occur at any age, including in the working age population, particularly for those living in the most deprived areas.

Figure 7 shows how the share of the population reporting good health deteriorates as people age. It also highlights that improving health means taking action over the life course through strategies that improve the living conditions experienced by all age groups. Only 50% of people living in the most deprived 10% of local areas in England report good health by age 55–59, compared to the same proportion reporting poor health a whole 20 years later at ages 75–79 for those from the 10% least deprived of local areas.

Making improvements in health across the life course also raises difficult measurement issues. There are currently several different measures for understanding how long people stay healthy. Disability-free life expectancy (DFLE), which will be used to measure progress towards the target contained in the Industrial Strategy, is based on a narrower definition of people reporting whether they have a disability or limiting illness than the alternative, healthy life expectancy (HLE), which is based on people reporting on the wider definition of whether they are in good health.

Both tell similar stories about years of health and inequalities, but HLE can capture a broader picture of health. The DFLE metric could lead to policies becoming more focused on the deterioration of health at older ages and extending workforce participation, rather than looking at strategies to enable people to stay healthy across the life course.
