4.3 Causes of Death

In Barnet, the top three broad causes of mortality in both men and women are circulatory diseases, cancers and respiratory diseases.[1] During 2015-17, circulatory diseases led to 2,319 deaths (males 1,097, females 1,222), cancers caused 1,853 deaths (males 943, females 910) and respiratory diseases resulted in 996 deaths (males 450, females 546). In the same period, mental and behavioural disorders were associated with 830 deaths, with almost twice as many deaths in females (n = 543) as in males (n = 287).[2] The percentages of deaths for 2015-17, broken down by gender and broad causes, are shown in Figures 4.1 and 4.2.

For 2016-18, female life expectancy in Barnet is 85.8 years, the 6th highest of all the London boroughs and significantly better than both London (84.5 years) and England (83.2 years).[3] For Barnet males, life expectancy is 82.4 years, which also the 6th highest of all the London boroughs and significantly better than both London (80.7 years) and England (79.6 years).[4]

Inequalities do however exist in the borough in life expectancy, based on gender, location and deprivation. Women in Barnet have a significantly higher life expectancy than men and the life expectancy of people living in the most deprived areas of the borough are on average 8.1 years less for men[5] and 7.6 years less for women,[6] than those in the least deprived areas, based on a comparison of the 10% most deprived and 10% least deprived areas in the borough.

At ward level, there is also disparity between wards in terms of life expectancy. Based on data for 2013-2017, the highest female life expectancy was found in Garden Suburb ward (89.5 years) and the lowest in Burnt Oak (81.7 years), a difference of 7.8 years. Figure 4.3 shows the life expectancy at birth for females in Barnet over this period. As can be seen from the map, the areas with higher female life expectancy are predominantly clustered in central and southern Barnet.[7]

Figure 4.4 shows the life expectancy for males in Barnet by ward. As with female life expectancy, the wards with higher life expectancy for males are generally clustered in the central and southern regions of the borough. Finchley Church End has the highest male life expectancy (86.7 years) and Burnt Oak the lowest (79.3 years), a difference of 7.4 years.[8]

During 2015-17, circulatory disease is the largest contributor to the gap in life expectancy between the most and least deprived quintiles in the borough for both sexes, accounting for a third (33.3%) of the gap in male life expectancy and a quarter (25%) of the gap in female life expectancy (refer to Figure 4.5). The second biggest contributor is respiratory disease, which accounts for about a fifth of the gap in life expectancy between the most and least deprived quintiles for both sexes.  The third greatest contributor to the life expectancy gap for both males and females is cancer, accounting for just less than a fifth of the gap in life expectancy in both sexes. In contrast, mental and behavioural causes (which includes dementia and Alzheimer’s disease) contributed 14.4% of the gap for females, compared with just 5% for males, over this period.[9]

For males, the three main causes of excess deaths in Barnet’s most deprived areas are heart disease, chronic lower respiratory disease and flu & pneumonia, whereas for females, the main causes of excess deaths are Alzheimer’s disease / dementia, “other circulatory disease” (i.e. not stroke or heart disease) and chronic lower respiratory diseases, during 2015-17.[10]

4.4 Causes of Ill Health

During 2016-18, there were a total of 1,996 premature (under 75 years) deaths in Barnet giving a directly standardised mortality rate of 236 per 100,000, which is significantly lower than both London and England and the 2nd lowest of all the local authorities in London.[11]

Table 4.1 below shows the premature (age <75 years) mortality rates associated with a number of leading causes of death. For 2016-18, with the exception of breast cancer, where the directly age standardised rate of mortality in Barnet (20.6 per 100,000) is similar to the rates for both the London (20.0 per 100,000) and England (20.4 per 100,000), premature mortality rates for all major causes of deaths are significantly lower in the borough, compared to regional and national averages.

Infant mortality (for infants aged <1 years) is also significantly lower in Barnet compared to London and England, as is mortality from lung cancer and COPD for all ages. Whilst the rates of smoking attributable deaths due to heart disease and stroke (for people aged over 35 years) in the borough are similar to the London average in both cases, they are still significantly lower than England rates. A similar pattern is seen for deaths linked to drug misuse (all ages) and the suicide rate in people aged over 10 years in Barnet (6.9 per 100,000) is also similar to London figure (8.1 per 100,000), although significantly lower than the England average (9.6 per 100,000).

Many of the conditions leading to premature mortality within the borough are strongly linked to lifestyle factors (such as smoking, poor diet, physical inactivity and alcohol consumption), so whilst the mortality rates are generally significantly lower than regional and national levels, there is still room for improvement. The major diseases linked to premature mortality in Barnet are covered in more detail in the following sections.

4.5 Cardiovascular Disease

Cardiovascular disease (CVD) is a general term for diseases of the heart and blood vessels as well as vascular diseases of the brain. It includes coronary heart disease (CHD), heart attack, hypertension, stroke and congenital heart disease. Worldwide, CVD is the largest cause of death and remains one of the major causes of preventable mortality. CVD is the number one killer disease globally and one of the major causes of preventable mortality.[12] In 2017, there were approximately 168,500 deaths due to CVD in the UK, of which 50.7% were male and 49.3% female. As a proportion of all deaths in that year, CVD accounted for 28.6% of deaths in men and 26.9% in women. There were 43,500 premature deaths in the UK due to CVD in 2017, which was 25.8% of all deaths due to CVD that year.[13]

During 2016-18, the premature (under 75) mortality rate in Barnet due to preventable CVD was 36.4 per 100,000.[14] The premature mortality rate from all cardiovascular disease for Barnet in 2016-18, was 54.8 per 100,000 (see Figure 4.6), which is significantly lower than the averages for both the England (71.7 per 100,000) and London (70.5 per 100,000). In terms of premature (under 75) mortality from all cardiovascular diseases, Barnet has the 5th lowest rate of all the 32 London boroughs (not including City of London).[15]

4.5.1 Coronary Heart Disease

For 2018/19, the recorded prevalence of coronary heart disease (CHD) for all ages in Barnet (2.4%) is significantly lower than England (3.1%), but significantly higher than the London average (2.0%). Compared with the other London boroughs, Barnet is ranked 7th highest on prevalence of CHD. During that year, 10,260 people in Barnet had coronary heart disease (CHD) recorded on their GP patient register, although there has been a downward trend in recent years in the recorded prevalence of CHD in the borough.[16]

The rate of hospital admissions for CHD (for all ages) in Barnet for 2018/19 was 410.2 per 100,000 which was the 7th lowest of the 32 London boroughs and significantly lower than the England average (488.2 per 100,000). During the 10-year period between 2008/9 and 2018/19, the rate of hospital admissions for CHD (all ages) in Barnet fell significantly from 712.4 per 100,000 to 410.2 per 100,000.[17]

4.5.2 Stroke

In 2018/19, the recorded prevalence of stroke or transient ischaemic attacks (TIAs) in the Barnet GP registered population was 1.2%, significantly lower than England (1.8%), but significantly higher than the London average (1.1%). This prevalence ranks Barnet 7th highest of the London boroughs. Based on this Quality Outcomes Framework (QoF) data, there are 5,318 people of all ages diagnosed as either having a stroke or TIA.[18]

The rate of stroke mortality in the under 75-year population is 8.0 per 100,000 in 2016-18, which is the lowest of all the London boroughs and significantly lower than the England average (12.8 per 100,000).[19]

In Barnet, the standardised mortality ratio (SMR) for deaths from stroke (all ages) for 2013-17, by ward was the highest in Woodhouse (104.0) followed by Coppetts (102.2). All other wards in Barnet have an SMR for stroke of less than 100, with the lowest rate found in Garden Suburb ward (51.3), where the SMR is statistically significantly lower that for Woodhouse and the England value (100.0). During this period, the SMR for stroke in Barnet (74.1) is also significantly lower than that for England overall (see Figure 4.7). [20]

For 2018/19, the rate of hospital admissions for stroke (all ages) in Barnet (199.5 per 100,000) is significantly higher than the national rate (166.0 per 100,000). Over the decade between 2008/9 and 2018/19, there has been a significant rise in the hospital admissions due to stroke in Barnet from a rate of 150.6 per 100,000 to 199.5 per 100,000.[21]

Between 2013/14 and 2017/18, the standardised admission ratios (SAR) for emergency hospital admissions for stroke (all ages, persons) in Barnet were highest in the wards Burnt Oak (146.5), Colindale (130.7) and Brunswick Park (117.9), while the lowest were in East Barnet (79.4), Finchley Church End (82.5) and Garden Suburb (83.6). For Barnet overall, the SAR for emergency hospital admissions for stroke during this period was 101.4, compared to an England figure of 100.0.[22] In contrast, the SARs for coronary heart disease (77.6), myocardial infarction (82.2) and all causes (78.8) for Barnet, are all significantly lower than England, during this period.[23]

4.5.3 CVD Prevention

There is considerable variation in the recorded prevalence of CHD (all ages) in the GP registered population of Barnet ranging from 0.2% to 3.5%, with a CCG average of 2.4%, for 2018/19. Although the recorded prevalence of CHD in Barnet is lower than the England average (3.1%), the significant differences between GP practices within the borough, warrants further investigation.[24]

For 2018/19, there is also considerable variation in the recorded prevalence of transient ischaemic attack (TIA) or stroke (all ages) in the GP registered population of Barnet, ranging from 0.3% to 2.1%, with a CCG average of 1.2%. Although the Barnet prevalence of stroke or TIA is lower than the England average (1.8%), there are statistically significant differences between GP practices in the borough, in terms of stroke prevalence.[25]

Within the borough, a range of initiatives have been implemented to reduce the effects of behavioural risk factors associated with CVD, such as physical inactivity, obesity, tobacco use and alcohol abuse.  The NHS Health Check Program[26] is one such initiative, aimed at spotting the early signs of heart disease, stroke, type 2 diabetes, kidney disease and dementia, through medical testing of people aged 40-74 years old.

Between Q1 2015/16 and Q3 2019/20, a total of 74,132 people in Barnet aged between 40 and 74 years were invited for an NHS Health Check (71.1% of those eligible). Of these eligible people, only 29.5% (n = 30,816) received an NHS health check during this period. This proportion was the 10th lowest of all the London boroughs and significantly lower than both England (39.5%) and London (43.1%). [27] [28]

4.6 Cancers

The three most common cancers in Barnet are breast, prostate and colorectal, as in both London and England. At the end of 2015, there were 10,102 cancer cases in Barnet, of which 56.5% were female and 43.5% male, with over half (54%) aged over 60 years. The overall prevalence rate for all cancers (all ages) is 2,661 per 100,000 in Barnet, which is lower than the national (England) average (3,270 per 100,000). Similarly, the prevalence in Barnet of breast cancer (734 per 100,000), prostate cancer (460 per 100,000) and colorectal cancer (272 per 100,000) is lower than the national average for breast (1,714 per 100,000), prostate (1,205 per 100,000) and colorectal (395 per 100,000) cancers. However, whilst the London average prevalence rates for breast (1,285 per 100,000) and prostate (888 per 100,000) cancers are higher than Barnet, London has a lower prevalence of colorectal cancer (253 per 100,000) and a lower overall cancer prevalence rate (2,416 per 100,000).[29]

4.6.1 Cancer Incidence

The standardised incidence rate for all cancers in Barnet CCG (515.20 per 100,000 person-years), is significantly lower than the average for England (594.43), in 2017. The incidence rates of both colorectal (53.10) and ovarian (14.38) cancers are also significantly lower than the national (England) average rates (68.13 and 22.58 per 100,000 person-years respectively). However, in contrast, the incidence rates (per 100,000 person-years) for Barnet CCG of breast (156.59), prostate (150.35), lung (68.26), stomach (8.45) and cervical (7.22) cancers are all similar the national rates for these cancers (i.e. 165.82, 172.89, 76.63, 10.27 and 9.36 per 100,000 person-years respectively).[30]

Data for 2012-16 shows that for new cases of cancer, the standardised incidence ratio (SIR) varies by the type of cancer across Barnet wards. Breast cancer incidence was the highest in Hendon (122.1) and the lowest in East Finchley (77.2). Oakleigh ward had the highest incidence (SIR) of colorectal cancer (100.0) and Hendon the lowest (61.3). Lung cancer incidence was lowest in Garden Suburb (50.9) and highest in East Finchley (107.7). The incidence of prostate cancer was highest in West Finchley (111.5) and lowest in Hendon (60.3). Overall, Burnt Oak has the highest incidence ratio (SIR) of all cancers (96.1) within the Barnet wards during 2012-16 and Coppetts the lowest incidence (80.9).[31]

4.6.2 Cancer Mortality

In 2018, Barnet had the 3rd lowest percentage of deaths with an underlying cause of cancer (25.8%) of any of the London CCGs. A lower proportion of people died from cancer in Barnet than in both London (27.5%) and England (27.2%).[32]

Similarly, in 2016-18, Barnet has the 3rd lowest premature (under 75 years) mortality from cancer (100.2 per 100,000) of all the London boroughs, significantly lower than the premature mortality rates for both London (120.1 per 100,000) and England (132.3 per 100,000).[33]

4.6.3 Cancer Survival

For Barnet adults (aged 15-99 years) diagnosed with cancer in 2016, the one-year survival index for all types of cancer combined (77.0%) is higher than the England average (72.8%). However, one-year survival for breast cancer in Barnet (96.6%) is similar to the England average (96.9%). Colorectal cancer patients in Barnet CCG, have a one-year survival of 86.8%, which is higher than the national average (80.6%). Similarly, the one-year survival for Barnet patients diagnosed with lung cancer in 2016, is 45.6%, which is higher than the England average of 41.6%.[34]

4.6.5 Cancer Registration

The “Be Clear on Cancer” programme[36] is a series of campaigns led by Public Health England, but delivered in partnership with NHS England, Cancer Research UK and the Department of Health to increase public awareness of the early signs of cancers and promote early diagnosis. Barnet CCG joined Be Clear on Cancer in July 2013, to promote the early detection of cancers in the borough.

During 2015-17, Barnet has the 5th lowest registration rate for lung cancer (62.3 per 100,000) within the London boroughs, which is significantly lower than the rates for both London (75.0 per 100,000) or England (76.8 per 100,000).[37]

Barnet also has the 3rd lowest registration rate for oral cancer (11.5 per 100,000) within the London boroughs in 2015-17, which is similar to London (14.4 per 100,000) but significantly lower than England overall (14.6 per 100,000).[38]

4.8 Mental Health

Mental illness represents a major challenge on a global scale, with an estimated 300 million people suffering from depression, 60 million from bipolar affective disorder, 50 million from dementia and 23 million from schizophrenia. To date, health systems internationally have not responded adequately to the burden created by mental disorders, creating a wide gap between the need for treatment and the provision of services.[46]

Against this background, the London Borough of Barnet have made the improvement of mental health and wellbeing a key priority within their Joint Health and Wellbeing Strategy.[47]  In 2016/17, Barnet CCG spent £62.5m on mental health, with a planned spend of £64.8m for 2017/18, representing 13.8% of their total allocation.[48]

4.8.1 Adult Mental Health

In 2018/19, the recorded prevalence (all ages) of mental health problems (including schizophrenia, bipolar affective disorder and other psychoses) for Barnet CCG is 1.04%, which is significantly higher than the rate for England (0.96%), but significantly lower than the London average (1.12%).[49]

Within Barnet CCG, almost 24,400 adults (aged 18+) are recorded in the depression registers within the GP surgeries, during 2018/19. The prevalence of adult depression in Barnet is 7.3%, significantly lower than the average for both London (7.6%) and England (10.7%).[50]

During 2018/19, there were 3,608 new cases of adult depression recorded in GP registers in Barnet, showing an incidence rate of 1.1% for Barnet, which is significantly lower than the rates for both England (1.7%) and London (1.2%).[51]

For 2019/20 (Q2), the rate of detentions in Barnet under the Mental Health Act is 48.4 per 100,000, which is similar to the national average (45.6 per 100,000), but lower than in London overall (69.3 per 100,000).[52]

For 2018/19, the rate of emergency admissions for intentional self-harm in Barnet (98.8 per 100,000) is significantly lower than the England average (193.4 per 100,000), but significantly higher than the rate for London (83.4 per 100,000). Compared to the other London boroughs, Barnet is ranked 8th highest in terms of emergency admissions for self harm.[53]

In contrast, the rate of hospital admissions for unintentional and deliberate injuries in children aged 0-14 years for Barnet during 2018/19 is 59.8 per 10,000, which is the 8th lowest of the London boroughs and significantly lower than both London (70.5 per 10,000) and England (96.1 per 10,000).[54]

However, the suicide rate (for people aged 10+) in Barnet (6.9 per 100,000), whilst similar to the rate for London (8.1 per 100,000), is significantly lower than the England average (9.6 per 100,000), during 2016-18.[55]  The suicide rate for males in the borough is significantly lower than the England average, whilst that for females is similar to the national rate. Additional detail on suicide rates in Barnet is provided by Figure 4.10, which depicts the quality and outcomes of the mental health services provided by Barnet and benchmarks them against England. Compared to national figures, Barnet has a significantly lower percentage of people in contact with secondary mental health services, living in stable and appropriate accommodation (both males and females), as well as a significantly lower proportion of service users satisfied with social care protection.[56]

4.8.2 Children's and Young People's Mental Health and Wellbeing

As shown in Figure 4.11, the estimated prevalence in Barnet of emotional disorders (3.2%), conduct disorders (5%) and hyperkinetic disorders (1.4%) in children aged 5-16 years are all lower than the national averages. However, the percentage of primary and secondary school children in Barnet with social, emotional and mental health needs, during 2018, is significantly higher than the national average. In contrast, hospital admissions for self-harm for children and young people aged 10-24 (272.0 per 100,000) is significantly lower than the national average (444.0 per 100,000), although significantly higher than the rate for London (195.8 per 100,000), during 2018/19.[57]

4.8.3 Prevention of Mental Illness

Child and adolescent mental health services (CAMHS) support children in their behavioural and emotional wellbeing.[58] The system is organized around four tiers, with Clinical Commissioning Groups (CCGs) responsible for tier 2 and 3 services and NHS England responsible for tier 4 services.

• The primary remit of tier 1 (universal) services is to support children and young people with mental health problems, rather than providing a mental health service per se.
• Targeted (tier 2) services are for children with milder mental health problems or increased risk of mental health problems.
• Tier 3 (specialist services) are provided by multi-disciplinary teams of child and adolescent mental health professionals accessed through GP referral.
• Specialised CAMHS (tier 4) include day and inpatient services as well as highly specialised outpatient services for specific conditions.[59]

The London Borough of Barnet (LBB) Health and Wellbeing Strategy highlights the council’s commitment to improve health and wellbeing, including mental health, through service provision and local commissioning. In November 2014, the Health and Wellbeing Board identified the early identification and prevention of mental health problems as a priority and are committed to the improvement of CAMHS services to reduce waiting times for eating disorders, lower A&E presentations and reduce self-harm hospital admissions.[60]

In line with the LBB Health and Wellbeing Strategy, 100% of urgent cases of eating disorder in children and young people were seen within one week within Barnet CCG in Quarter 2 (Q2) of 2019/20. During the same period, 89.6% of routine cases of eating disorder were seen within 4 weeks. For the 2019/20 financial year, the planned spend for Children and Young People’s (CYP) mental health services (excluding learning disabilities and eating disorders) was £5.7m, compared with a planned spend of 79.0m for mental health overall in Barnet CCG.[61]

4.9 Diabetes

4.10 Oral health

Oral health is much more than having good teeth; it is essential for wellbeing and an integral part of general health. The interrelationship between oral and general health is supported by evidence, with a strong correlation between several oral diseases and noncommunicable chronic diseases (e.g. diabetes is associated with severe periodontal disease). The early detection of oral disease can be important in saving lives, through the identification of signs of oral cancer, immune disorders, microbial infections, nutritional deficiencies and injuries. Proper oral health care not only reduces premature mortality, but can also significantly improve quality of life, whilst reducing the impact on everyday activities from dental disease. Despite this, oral health remains a significant problem across the world, with dental caries still a major issue in most industrialized countries, affecting most adults and between 60-90% of children.[74]

In this context, the World Health Organization (WHO) emphasizes the importance of availability and accessibility of oral health systems in the control of oral disease. Similarly, reduction of the risks associated with oral disease is only possible by orientating services towards primary health care and prevention. The role of services to address modifiable risk behaviours, such as the excessive consumption of sugar, tobacco and / or alcohol, is also underlined as part of an effective strategy.[75]

Worldwide, oral cancers are the 6th most common, although they are less prevalent in the UK, with about 8,300 people diagnosed each year (accounting for about 2% of all cancers diagnosed). Also known as “mouth cancers,” they are more common in men than women and also in older adults, aged over 55.[76]

In the period 2015-17, the directly standardised rate of oral cancer registrations in Barnet is 11.5 per 100,000, which is significantly lower than the national average (14.6 per 100,000).[77]

In the UK, tobacco and drinking alcohol are the leading causes of oral cancers. Other risk factors include; chewing tobacco, poor diet, chewing betel nut and infection with human papilloma virus (HPV), which are a family of viruses affecting the moist linings of the body and skin.[78] 

When oral cancer is diagnosed early, it can be treated through surgery alone, with a very good chance that the cancer is permanently cured. For this reason, increasing awareness of the risk factors for oral cancer within the community, reducing smoking and alcohol consumption and encouraging early reporting of symptoms are important.[79]

4.10.2 Child Oral Health

As part of Public Health England’s National Dental Epidemiology Programme (NDEP), a survey of 5 year old children was undertaken. The severity of decay was assessed using the average d3mft (the number of decayed teeth and those missing or filled due to decay). The results of this survey were reported in 2018 and Barnet was found to have an average d3mft similar to most other London boroughs and the national average.[80]

Figure 4.13 depicts the average number of decayed, missing or filled teeth (d3mft) in Barnet five year olds in 2017, compared to England, London and other London local authorities. The average d3mft for Barnet (0.8) is similar to both England (0.8) and London (0.9). Out of the 32 London boroughs, Barnet is ranked 20th out of 32, in terms of d3mft.[81]

From the opposite perspective, the proportion of five year old children who were free from obvious dental decay (Public Health Outcomes Framework indicator 4.02) for Barnet (68.0%) in 2014/15 was significantly lower than the national (England) average (75.2%), but similar to the London average (72.6%).[82]

Hospital admissions for extraction of one or more primary or permanent teeth in children aged 0-19 years are shown in Figure 4.14. The number of finished consultant episodes as a percentage of the population was lower in Barnet for children aged 0-9 years, compared with London and England. However, for those aged 10-19 years, the percentage in Barnet was either similar or higher than the national average.[83]

Child dental access in Barnet, London and England changed little between 2015/16 and 2016/17. For Barnet, 44.6% of children aged 0-17 were seen in the previous 12 months for 2015/16 compared to 45.5% for 2016/17. Similarly, for London 48.9% of children were seen in the previous 12 months for 2015/16 compared to 49.2% for 2016/17. For England, the dental access figures for children were higher for both years; 58.0% for 2015/16 and 58.2% for 2016/17.[84]

4.10.3 Oral Health Needs

There is currently no borough level data on the oral health of adults in Barnet, so a health needs assessment of their oral health could be undertaken, to identify oral health inequalities and needs within this population.

4.11 Maternity and infant health

4.11.1 Live Births and Rates

In 2018, there were 5,111 live births in Barnet. Only 1.1% to mothers were less than 20 years old, compared with 35.6% aged 30-34 years old. 

The highest fertility rate in Barnet was in women aged 30-34 years (115.4 per 1,000 women) in Barnet, compared to 101.9 per 1,000 for London and 107.2 per 1,000 in England, for the same age group. The General Fertility Rate (GFR: all live births for women aged 15-44 years) in 2018 was 63.4 per 1,000 women in Barnet, compared with 60.2 per 1,000 in London and 59.2 per 1,000 for England overall. The Crude Birth Rate (CBR: the number of live births per 1,000 population of all ages) was 13.0 per 1,000 for the borough, compared with 13.5 per 1,000 in London and 11.2 per 1,000 in England, for 2018. In contrast, the average age of mothers was quite similar across the three geographies: Barnet (31.7 years), London (31.8 years) and England (30.6 years).[85]

Between 2020 and 2035, the number of women of child-bearing age in Barnet is projected to rise from about 79,900 to 84,600, an increase of 5.9% over the period.[86] 

Based on fertility trend data from the Greater London Authority for 2020, the wards with the highest General Fertility Rate (GFR) are Golder’s Green (78.2 per 1,000) and Edgware (74.8 per 1,000). The predicted GFR for both these wards is significantly higher than for Barnet overall (61.3 per 1,000). In contrast, the wards with the lowest GFR, Brunswick Park (51.5 per 1,000) and East Finchley (51.9 per 1,000) are not significantly different from the borough GFR.[87]

4.11.2 Infant Health and Mortality

In 2018, the percentage of live births (at term) under 2.5 kg in Barnet (2.79%), is similar to both England (2.86%) and London (3.07%).[88] Data for 2011-2015, show that in Barnet wards, the percentage of live births which were low birth weight (< 2,500 g) was highest in Totteridge (4.2%) followed by Brunswick Park (3.5%) and Finchley Church End (3.5%). The wards with the lowest proportion of underweight births were Garden Suburb (2.2%), followed by Mill Hill (2.3%) and Oakleigh (2.4%).[89]

During 2016-18, the infant mortality rate (for children aged under 1 year) in Barnet (2.2 per 1,000 live births) is the 3rd lowest of the London boroughs and significantly better than both London (3.3 / 1,000) and England (3.9 / 1,000).[90] Similarly, the neonatal mortality (number of deaths under 28 days per 1,000 live births) in Barnet (1.54 per 1,000 live births) is the 6th lowest of the London boroughs for the same period and significantly better than England (2.83 / 1,000), although not significantly different from the London rate (2.34 / 1,000).[91]

4.12 Health Protection

4.12.1 Immunization

The process of making someone immune or resistant to an infectious disease is called “immunization” and often involves the administration of a vaccine which stimulates the person’s own immune system to combat subsequent disease or infection.[96] The NHS has developed a complete routine immunization schedule which provides information to healthcare professionals on the vaccines which protect against specific diseases and at what age they should be administered.[97]

4.12.1.1 Childhood Primary Immunizations

NHS routine childhood immunizations provide cover against a number of infectious diseases including: diphtheria, influenza, whooping cough, polio and tetanus. Evaluation of childhood immunization in England is conducted through the cover of vaccination evaluated rapidly (COVER) programme, which produces quarterly statistics.[98]

NHS immunization statistics for 2016/17 and Childhood Vaccination Coverage Statistics, 2016/17 (Table 4.2) show that Barnet rates for all childhood immunizations are lower compared to the national average.

4.12.1.2 Human Papillomavirus (HPV) Immunization

The human papillomavirus (HPV) immunization programme was introduced nationally in 2008, to protect girls from the main cause of cervical cancer. Originally, it was a three-dose vaccination, but following expert advice, it has been run on two dose schedules since September 2014. In Barnet, the percentage of girls aged 13-14 in 2016/17, who had received both HPV doses is 75.4% which is significantly lower than both London (77.7%) and England (83.1%) and ranked 23rd out of 32 London boroughs.[99]

4.12.1.3 Flu and Pneumococcal (PCV) Immunization

During 2018/19, almost two-thirds (65.4%) of the Barnet population aged 65+ were vaccinated against influenza, which was the same as the London average (65.4%), but significantly lower than the national figure (72.0%).[100] Similarly, for at risk individuals, only 43.9% in Barnet received a flu vaccination during 2018/19, which was similar to the London average (44.4%), but significantly lower than the national average (48.0%).[101]

Pneumococcal Conjugate Vaccine (PCV) provides protection against the bacteria that cause pneumococcal disease, which can cause a range of serious health problems. During 2018/19, a total of 4,710 children in Barnet received two doses of PCV before their first birthday, providing a vaccination coverage rate of 87.3%, compared to 88.2% in London and 92.8% nationally.[102]

In 2018/19, a total of 36,988 people in Barnet aged 65 years received one dose of pneumococcal polysaccharide vaccine (PPV) as immunization against pneumococcal disease. During this period, the PPV vaccination rate in Barnet is 67.0%, compared with 64.2% in London and 69.2% in England overall.[103]

4.12.2 Tuberculosis

Tuberculosis (TB) is a curable, preventable disease caused by the bacteria Mycobacterium tuberculosis. It is a contagious, airborne disease that is one of the top 10 causes of death worldwide and the top infectious killer globally. In 2016, there were an estimated 10.4 million new (incident) cases of TB and 1.7 million people died from the disease, although between 2000 and 2016, an estimated 53 million lives were saved through TB diagnosis and treatment.[104]The UK has one of the highest incidence rates of TB in Western Europe and local authorities play an important role in addressing this issue, which disproportionately affects disadvantaged and vulnerable groups such as migrants, ethnicity minorities and those with social risk factors such as homelessness or a history of imprisonment.[105]

Figure 4.15 shows the 3-year aggregated rate of TB incidence, for Barnet, London and England, between 2002-4 and 2015-17. Since 2010, the incidence rate of TB has declined significantly in Barnet, London and England, however, compared to England, the rates are still high in London and the Barnet. In recent years, the incidence of TB in Barnet has remained significantly lower than London and significantly higher than England. For example, during 2015-17, TB incidence in Barnet (18.4 per 100,000) was significantly lower than London (24.3 per 100,000), but significantly higher than England (9.9 per 100,000) (see Appendix to the JSNA).[106]
