Life Expectancy At Birth By Gender and by Electoral Ward For Barnet
1. Life expectancy at birth by gender and by electoral ward for Barnet
The foundations set out in the Government’s White Paper Our Health, Our Care, Our Sayi
proposed helping people stay healthy and independent whilst providing choice in their care
services and to tackle inequalities in health. As a result, Barnet Council and Barnet PCT
seeking to commission care that encourages independence, promotes greater choice and that
will help communities to develop local networks of support which can improve health and
wellbeing, as well as encouraging people to live independently as long as possible.
Barnet’s Community Strategyii outlines its vision on improving the social, economic and
environmental well-being of the borough. It focuses on four key themes:
investing in children and young people
a safer, stronger and cleaner Barnet
growing successfully
a healthier Barnet (including sub theme: older people).
The government continues to emphasise the importance of tackling ‘health inequalities’, i.e.
significant differences in health and well-being and access to health care that still exist between
different groups in our society. There are differences in life expectancy, hospital admission
rates, the risk of serious accidents and the risk of death from illness in different parts of the
borough. Differences in life expectancies in different parts of the borough are shown in Figure
1.
The main causes of ill-health death
The main causes of ill-health and death have changed in the last 150 years from infections
such as measles and TB, accidents and malnutrition, to diseases such as heart attack, stroke
and cancers. This shift from infectious and respiratory disease deaths to circulatory (principally
coronary heart disease and stroke) deaths is shown in Figure 2.

These changes principally come about because of the widespread availability of a clean
drinking water supply, the introduction of universal childhood immunisation, better housing and
better food. But this has led to diseases related to lifestyle becoming more common. Many
years ago, a doctor called Elliot Joslin said, “Genes load the gun, but it’s lifestyle that pulls the
trigger”. In other words, many of us may have a genetic predisposition to certain diseases, but
how we choose to live our lives will influence whether we develop those diseases or not and, if
we do, how severely they will affect us.
This is most apparent with smoking, which is the most important preventable risk factor for
death from cancer and cardiovascular disease.iv,v (It is also important to remember that, in
addition to the unequivocal evidence that smoking damages the smoker’s health, there is also
substantial evidence that exposure to second-hand tobacco smoke (e.g. smoke from other
people’s cigarettes) harms non-smokers.vi,vii,viii,ix,x )
A further example of the way in which our own lifestyle can affect our health is overweight and
obesity. In 2004, a House of Commons select committee noted that ‘On present trends, obesity
will soon surpass smoking as the greatest cause of premature loss of life. It will bring levels of
sickness that will put enormous strains on the health service, perhaps even making a publicly
funded health service unsustainable.’xi
Overweight and obesity increases the risk of developing diabetes and high blood pressure
(itself a risk factor for stroke). Overweight and obesity increases the risk of developing arthritis,
especially of the hip and knee. And obesity, a high fat diet and inactivity have also been shown
to increase the risk of breast cancer.xii,xiii shows the ‘relative risk’ (i.e. how much more (or less)
something is likely to occur) of developing different diseases in people who are obese. For
example, Table 1 shows that an obese woman is nearly 13 times as likely to develop diabetes
4. as one who is not obese, and an obese man is three times as likely to develop bowel cancer as
one who is not obese.

Another example of lifestyle issues affecting health is the misuse of alcohol. In addition to
alcoholic liver disease, alcohol misuse can cause a variety of health and other problems. For
example, driving under the influence of alcohol substantially increases the risk of having an
accident. Excessive alcohol intake is associated with antisocial behaviour and street violence,
as well as domestic violence. Alcohol is implicated in 78% of assaults and 88% of criminal
damage.xv Excessive alcohol intake also affects people’s ability to work and, when it becomes a
significant problem, this can often lead to job loss.xv
