Adults' health

Summary

This report examines the general health of adults aged 16 and over, as well as the prevalence of diabetes, raised cholesterol and hypertension. These are established risk-factors for cardiovascular diseases (CVD). The prevention of CVD can result in reductions in premature mortality and morbidity. CVD has been identified as a clinical priority in the NHS Long Term Plan (Source: NHS England). Detailed tables accompanying this report can be accessed here


Key findings

  • In 2024, 46% of adults aged 16 and over had at least one longstanding illness or condition. A higher proportion of women (48%) than men (44%) had a longstanding illness.  
  • 18% of adults reported that they had acute sickness in the past two weeks. The prevalence of acute sickness was higher among women (20%) than men (16%). 
  • The prevalence of total diabetes, including doctor-diagnosed and undiagnosed diabetes, was 9%. This comprised 7% of adults with doctor-diagnosed diabetes and 2% with undiagnosed diabetes. 
  • The proportion of adults with raised cholesterol was 48%. This was greater among women (50%) than men (45%). The proportion increased with age. Among women it was highest among those aged 55 to 64 (72%); among men it was highest among those aged 45 to 54 (65%).  
  • 30% of adults had hypertension (high blood pressure), with men (32%) more likely to have hypertension than women (27%). Untreated hypertension increased with age, with prevalence highest among those aged 75 and over (18%). 

General health

Background

Self-assessed general health is an important indicator of the general health of the population. It is a valid measure for predicting future health outcomes and can be used to project use of health services and provide information useful for policy development. In older people, self-assessed poor overall health has been associated with increased mortality risk (Source: Mossey and Shapiro, 1982) and functional decline (Source: Idler and Kasi, 1995). 

Methods and definition

Participants were asked ‘how is your health in general?’ and offered five response options: very good, good, fair, bad, or very bad. The responses to this question are described as self-reported general health. 

Self-reported general health and sex

In 2024, 72% of adults reported good or very good general health. 19% said their health was fair and 9% reported bad or very bad health. 

For more information: Table 1

Acute sickness

Definition

Acute sickness is defined as any illness or injury (including any longstanding condition) that has caused the participant to cut down on things they usually do in the last two weeks. 

Acute sickness by sex

18% of adults reported that they were affected by acute sickness in the past two weeks. The prevalence of acute sickness was higher among women (20%) than men (16%). 

Longstanding conditions

Background

Longstanding conditions affect the body or mind for 12 months or more. Most longstanding conditions increase in prevalence with age, and vary in their effects on individuals, from minimal impact to disability. Most longstanding conditions are managed in the community, but some require inpatient stays, or domiciliary or residential care. Some of the longstanding conditions treated by GPs are monitored through the Quality Outcomes Framework (QOF) for prevalence and achievement of treatment targets. 

Methods and definitions

The questions on longstanding conditions are included in the main HSE interview. Prior to 2012, the question referred to ‘an illness, disability or infirmity…that has troubled you over a period of time or that is likely to affect you over a period of time’. In 2012, the questions on longstanding conditions were changed to be consistent with the Office for National Statistics (ONS) harmonised disability questions designed for use in social surveys (HSE 2012). Participants were asked the question ‘do you have any physical or mental health conditions or illnesses lasting or expected to last 12 months or more?’ 

Participants who reported that they had a physical or mental health condition or illness lasting or expected to last 12 months or more were further asked ‘what is the matter with you?’, and their answers for up to six conditions were recorded verbatim. These were coded into 42 conditions, which were further grouped into the 14-chapter categories of the ICD-10, covering infectious and non-communicable diseases of the body and mind. 

 

What is ICD-10?

ICD-10 is a medical classification list by the World Health Organization (WHO) and stands for the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (Source: ICD-10). Each ICD-10 chapter covers a system, or group of organs, which work together to carry out a function, e.g. VII Diseases of the eye and adnexa covers the eye, eyelids and optic nerve; whilst XI Diseases of the digestive system covers conditions of the mouth, oesophagus, stomach, intestines, liver, gallbladder, and pancreas.

Prevalence of longstanding conditions, by sex

In 2024, 46% of adults aged 16 and over had at least one longstanding illness or condition. Participants could record up to six conditions. Therefore, the overall prevalence of having any longstanding condition is lower than the combined prevalence of individual conditions.

Survey estimates are subject to a margin of error (see ‘About the survey estimates’ in the Introduction to this report. It is likely that in 2024 the proportion of adults with longstanding conditions was between 41.9% and 46.2% among men and 45.8% to 49.5% among women.

The most common conditions were:

  • conditions of the musculoskeletal system (17%)
  • mental, behavioural and neurodevelopmental conditions (12%)
  • conditions of the heart and circulatory system (11%)
  • diabetes and other endocrine and metabolic conditions (9%)
  • conditions of the respiratory system (8%)

Other types of longstanding conditions had prevalence levels of 5% or below.

Women were more likely than men to have one or more longstanding conditions (48% compared with 44%).

Among the most common conditions, women were more likely than men to have: 

  • musculoskeletal conditions (19% compared with 14%). 
  • mental, behavioural and neurodevelopmental conditions (14% compared with 11%). 

Heart and circulatory conditions were more commonly reported by men than women (12% compared with 10%).

Diabetes

Background

Diabetes is characterised by high blood glucose levels (hyperglycaemia). 

Untreated, hyperglycaemia is associated with damage and possible failure of many organs, especially the eyes, kidneys, nerves, heart, and blood vessels. Diabetes substantially increases the risk of cardiovascular disease (CVD) and tends to worsen the effect of other risk factors for CVD, such as abnormal levels of blood fats, raised blood pressure, smoking and obesity (Source: Garcia et al, 1974). Diabetes (both Types 1 and 2) is a leading cause of avoidable mortality. (Source: World Health Organization)

Methods and definitions

The HSE measures diabetes in two ways. The prevalence of self-reported doctor-diagnosed diabetes is included in the main interview.

In addition to the interview question, glycated haemoglobin (HbA1c) levels are measured in blood samples collected during the health visit. HbA1c reflects average blood sugar levels over the previous two to three months and can therefore be used both to monitor diabetic control in people with diagnosed diabetes, and to detect undiagnosed diabetes (Source: World Health Organization, 2011).

The presence of doctor-diagnosed diabetes is identified if a participant answers yes to two questions: 

  • do you now have, or have you ever had, diabetes? 
  • were you told by a doctor that you had diabetes? 

This report does not distinguish between Type 1 and Type 2 diabetes. 

Total diabetes in the population includes all participants who reported having doctor-diagnosed diabetes, as well as those with a blood sample measured as having an HbA1c level of 48mmol/mol or above, diagnostic of diabetes. Participants with a raised HbA1c who did not report having doctor-diagnosed diabetes are defined as having undiagnosed diabetes.

How have definitions of diabetes changed on HSE?

In earlier years (up to HSE 2003), it was assumed that participants who reported having doctor-diagnosed diabetes before the age of 35 and who were having insulin therapy at the time of the survey, had Type 1 diabetes, and all other participants with doctor-diagnosed diabetes were classified as having Type 2 diabetes. However, increasing numbers of people are now being diagnosed with Type 2 diabetes below the age of 35 and some adults with Type 2 diabetes are now prescribed insulin therapy, so these distinctions are no longer reliable. The prevalence of diagnosed and undiagnosed (total) diabetes is presented from 2011 onwards. Values of HbA1c were adjusted in 2013 (4th quarter) and each year from 2014 onwards to make them comparable to previous data, due to changes in calibrators.

Further details of the protocols for collecting measurements and blood samples can be found in the HSE 2024 Methods, available on the first page.

Prevalence of doctor-diagnosed diabetes, by age and sex

In 2024, 8% of adults reported that a doctor had told them that they had diabetes.

The prevalence of doctor-diagnosed diabetes was higher among men (10%) than women (6%). Prevalence increased with age, from 1% of adults aged 16 to 24 to 16% of adults aged 75 and over.

For more information: Table 3

Prevalence of total diabetes, by age and sex

Estimates of the prevalence of total diabetes, using glycated haemoglobin levels, are limited to participants with a health visit and a valid HbA1c measurement.

Consequently, the estimates of those with doctor-diagnosed diabetes in Tables 4 and 5, which are limited to only those with a blood sample, vary slightly from those in Table 3 which shows the definitive estimates.

In 2024, the prevalence of total diabetes was 9%, comprised of 7% of adults with doctor-diagnosed diabetes and a further 2% with undiagnosed diabetes.

Prevalence of total diabetes increased with age, from 2% of adults aged 16 to 44 to 17% of adults aged 65 and over. The prevalence of total diabetes was higher among men (12%) than women (7%).

The prevalence of undiagnosed diabetes also increased with age, with different patterns for men and women. Among men, the prevalence was highest among those aged 45 to 64 (6%), whereas for women it was highest among those aged 65 and over (4%).

For more information: Table 4

Prevalence of total diabetes, by area deprivation

How has area deprivation been defined?

The English Index of Multiple Deprivation (IMD) is a measure of area deprivation, based on 37 indicators, across seven domains of deprivation. IMD is a measure of the overall deprivation experienced by people living in a neighbourhood, although not everyone who lives in a deprived neighbourhood will be deprived themselves. To enable comparisons, areas are classified into quintiles (fifths). For further information about the IMD, see the HSE 2024 Methods, available on the first page.

Prevalence of total diabetes by area deprivation is shown in the tables as age-standardised. 

What is age-standardisation?

Observed data show the actual prevalence rate found in the survey. Age-standardised data take into account the different age profiles within different areas enabling comparisons between these areas.

When controlling for age, prevalence of total diabetes generally increased with the level of area deprivation. 14% of adults living in the most deprived areas had total diabetes compared with 5% living in the least deprived areas.

The pattern by area deprivation differed for men and women, with the difference between the most and least deprived areas being larger for men. Prevalence of total diabetes among men varied from 7% in the least deprived areas to 17% in the most deprived areas. This compared with 4% in the least deprived areas and 11% in the most deprived areas among women.

For more information: Table 5 

Note that in 2021 self-reported diagnosed and undiagnosed diabetes came from the main interview, where the survey methodology differed to other years. HSE data collection was paused in 2020 due to pandemic-related restrictions, meaning that insufficient data was collected for reporting. There was no annual survey in 2023.


Cholesterol

Background

Cholesterol is a fatty substance (also referred to as a lipid) found in the blood and is needed by the body to function. There are different types of cholesterol including LDL (low density lipoprotein) cholesterol, VLDL (very low-density lipoprotein) cholesterol, and HDL (high density lipoprotein) cholesterol. 

HDL cholesterol is beneficial, as it carries cholesterol away from the arteries back to the liver, where it can be excreted. Too much non-HDL cholesterol is harmful as it can clog blood vessels, causing them to become stiff and narrow, reducing blood flow. High cholesterol is a significant risk factor for cardiovascular disease (CVD), including narrowing of the arteries (atherosclerosis), heart attack (Source: Peters et al, 2016) and stroke (Source: Law, Wald and Rudnicka, 2003). 

Methods and definitions

In the HSE, cholesterol levels are measured via blood samples taken at the health visit. 

Measuring cholesterol

The prevalence of raised total cholesterol is presented for the years 1998, 2003, 2006, 2011, 2014, 2017, 2018, 2019, 2021, 2022 and 2024. Values from 2011 and 2014 have been adjusted to make the measurements comparable to measurements made before HSE 2010, when there was a change in calibrators. A further change in calibrators in 2015 resulted in equivalence between current measurements and those prior to 2010. 

Full details of the HSE blood sample protocols, analytical methods and equipment can be found in the HSE 2024 Methods, available on the first page.

Less than optimum cholesterol levels are one of several factors that might indicate a greater risk of cardiovascular diseases. These are calculated and defined as follows (Source: British Heart Foundation, NHS England):

  • raised total cholesterol is defined as total cholesterol equal to or greater than 5mmol/L
  • lower level of HDL cholesterol (good cholesterol) is defined as below 1mmol/L for men and 1.2mmol/L for women
  • the total/HDL ratio was calculated by dividing total cholesterol by HDL cholesterol, which is a measure of how much good cholesterol someone has compared with their total cholesterol, and should be as low as possible. A value equal to or greater than 6 is considered high risk (the measure is above established and widely acknowledged limits for healthy levels of cholesterol).

Raised total cholesterol, by age and sex

In 2024, the proportion of adults with raised cholesterol was 48%. This was higher among women (50%) than men (45%).

The prevalence of raised cholesterol varied by age, with different patterns for men and women. Among women, prevalence rose steadily with age up to a peak among those aged 55 to 64 years (72%). Among men, the proportion increased more steeply among younger age groups than seen for women and was highest among those aged between 45 and 54 (65%). Among adults aged 55 and over, the proportion with raised cholesterol was consistently higher among women than men.

For more information: Table 7 

The proportion of adults aged 16 and over with low HDL cholesterol was 13%.

5% of adults had a total/HDL ratio of 6 or above, indicating high risk (the measure is above established limits for healthy levels of cholesterol). This proportion was higher among men (7%) than women (3%). The prevalence of a total/HDL ratio of 6 varied by age and was highest among adults aged 45 to 54 (9%).

For more information: Table 6 and Table 7

Raised total cholesterol, by area deprivation

How has area deprivation been defined?

The English Index of Multiple Deprivation (IMD) is a measure of area deprivation, based on 37 indicators, across seven domains of deprivation. IMD is a measure of the overall deprivation experienced by people living in a neighbourhood, although not everyone who lives in a deprived neighbourhood will be deprived themselves. To enable comparisons, areas are classified into quintiles (fifths). For further information about the IMD, see the HSE 2024 Methods, available on the first page.

Prevalence of raised total cholesterol by area deprivation is shown in the tables as age-standardised. 

What is age-standardisation?

Observed data show the actual prevalence rate found in the survey. Age-standardised data take into account the different age profiles within different areas enabling comparisons between these areas.

The prevalence of raised cholesterol did not vary by area deprivation.

For more information: Table 8

Data for HSE 2012, 2013, 2015, 2016 are not shown. HSE data collection was paused in 2020 due to pandemic-related restrictions, meaning that insufficient data was collected for reporting. There was no annual survey in 2023.


Hypertension

Background

Hypertension (persistent high blood pressure) is an important public health challenge worldwide because of its high prevalence and the associated risk of cardiovascular disease (CVD). It is one of the most important modifiable risk factors for stroke, ischaemic heart disease (such as angina, heart attacks, and heart failure) and renal disease, and it is one of the most preventable and treatable causes of premature deaths worldwide (Source: World Health Organization, 2025). 

Methods and definitions

Trend data on the prevalence of hypertension are presented for 2003 and from 2005 onwards, using measurements taken with the Omron HEM207 sphygmomanometer to measure blood pressure. 

The HSE cannot be completely accurate in identifying people with hypertension as the definition requires persistently raised blood pressure. The HSE measures the blood pressure of each participant three times but on a single occasion.

Hypertension categories

High blood pressure is defined in this report as a systolic blood pressure (SBP) at or above 140mmHg or diastolic blood pressure (DBP) at or above 90mmHg or being on medication prescribed for high blood pressure. Participants are classified into one of four groups as follows: 

  • normotensive untreated: SBP below 140mmHg and DBP below 90mmHg, not currently taking medication for blood pressure
  • hypertensive controlled: SBP below 140mmHg and DBP below 90mmHg, currently taking medication for blood pressure
  • hypertensive uncontrolled: SBP at or greater than 140mmHg and/or DBP at or greater than 90mmHg, currently taking medication for blood pressure
  • hypertensive untreated: SBP at or greater than 140mmHg and/or DBP at or greater than 90mmHg, not currently taking medication for blood pressure
Changes in blood pressure medication coding on HSE

In 2024, there was a variation in the way that medications for blood pressure were coded, which included the addition of new medications (Source: NICE). This may have slightly affected comparability with estimates from previous years. Specifically, compared with previous estimates, the change to the coding may have resulted in a small increase in the number of participants classified as on blood pressure medication and a decrease in the number of participants classified as hypertensive untreated.

Doctor-diagnosed and undiagnosed hypertension

The presence of doctor-diagnosed hypertension is identified if a participant answers yes to two questions: 

  • do you now have, or have you ever had, high blood pressure sometimes called hypertension?
  • were you told by a doctor or nurse that you had high blood pressure?

Undiagnosed hypertension is defined as participants with a systolic blood pressure (SBP) at or above 140mmHg or diastolic blood pressure (DBP) at or above 90mmHg, who did not report having doctor-diagnosed hypertension. It differs from the definition of hypertension categories in Tables 10 to 11, as it does not consider information on medication. The combined proportion of those in the population with doctor-diagnosed and undiagnosed hypertension is referred to as total hypertension.

Prevalence of hypertension, by age and sex

30% of adults aged 16 and over had hypertension (high blood pressure). Survey estimates are subject to a margin of error (see ‘About the survey estimates’ in the Introduction. It is likely that in 2024 the proportion of adults with hypertension was between 27.7% and 31.5%, which is similar to previous years.

Hypertension was more prevalent among men (32%) than women (27%).

The prevalence of hypertension increased with age and was highest among those aged 75 and over for both men (67%) and women (70%). The increase by age was steeper among younger age groups for men than for women.

The proportion of adults with untreated hypertension (SBP at or greater than 140mmHg and/or DBP at or greater than 90mmHg, not currently taking medication for blood pressure), was 12%. This increased with age, from 1% among those aged 16 to 24 to 18% among those aged 75 and over. Untreated hypertension was more common among men (13%) than women (10%).

For more information: Table 9 and Table A4

Note that due to rounding totals may sum to more or less than 100%

Prevalence of hypertension, by area deprivation

How has area deprivation been defined?

The English Index of Multiple Deprivation (IMD) is a measure of area deprivation, based on 37 indicators, across seven domains of deprivation. IMD is a measure of the overall deprivation experienced by people living in a neighbourhood, although not everyone who lives in a deprived neighbourhood will be deprived themselves. To enable comparisons, areas are classified into quintiles (fifths). For further information about the IMD, see the HSE 2024 Methods, available on the first page.

 The prevalence of hypertension by area deprivation is shown in the tables as age-standardised. 

What is age-standardisation?

Observed data show the actual prevalence rate found in the survey. Age-standardised data take into account the different age profiles within different areas enabling comparisons between these areas.

The age-standardised prevalence of hypertension, and untreated hypertension, did not vary by area deprivation. 

For more information: Table 10

Changes in blood pressure medication coding on HSE

In 2024, there was a variation in the way that medications for blood pressure were coded, which included the addition of new medications (Source: NICE). This may have slightly affected comparability with estimates from previous years. Specifically, compared with previous estimates the change to the coding may have resulted in a small increase in the number of participants classified as on blood pressure medication and a decrease in the number of participants classified as hypertensive untreated.

 

HSE data collection was paused in 2020 due to pandemic-related restrictions, meaning that insufficient data was collected for reporting. There was no annual survey in 2023. Changes to the coding of medications for blood pressure medication in 2024 may have slightly affected comparability of estimates. See note above for further information: Changes in blood pressure medication coding on HSE

Prevalence of doctor-diagnosed and undiagnosed hypertension, by age and sex

Total hypertension is the combination of doctor-diagnosed hypertension and undiagnosed hypertension. It differs from the estimates of ‘all with hypertension’ in Table 9 which includes information from the health visit on blood pressure readings and reporting a doctor-diagnosis. By contrast, the definitions in Table 11 are based on information on blood pressure readings and blood pressure medication.

Note that doctor-diagnosed hypertension may include participants who have reported a diagnosis of hypertension but who do not have high blood pressure readings at the time of the health visit and are not on medication (this could, for example, be a result of them controlling their blood pressure through lifestyle changes). Therefore, estimates of hypertension may be greater using this method.

Total hypertension was recorded for 32% of adults aged 16 and over, with higher prevalence among men (36%) than women (30%). The prevalence of total hypertension increased with age and was highest among those aged 75 and over among both men (70%) and women (72%) but increased more steeply from age 35 among men than among women.

The proportion of adults with undiagnosed hypertension was 9%. This increased with age and was highest among those aged 75 and over (15%).

For more information: Table 11

Prevalence of doctor-diagnosed and undiagnosed hypertension, by region

Hypertension estimates by region are shown in the tables as both observed and age-standardised.

What is age-standardisation?

Observed data show the actual prevalence rate found in the survey. Age-standardised data take into account the different age profiles within different areas enabling comparisons between these areas.

When controlling for age, the proportion of adults with total and undiagnosed hypertension did not vary by region.
