Smoking is the greatest preventable
cause of premature death and avoidable illness. In Northern Ireland
there are 2700 - 3000 deaths per annum as a result of smoking (1200
in the Eastern Board area).
It is a major risk factor for coronary
heart disease, strokes
and other diseases of the circulatory
system, which kill two in every five men and women here.
A lifetime non-smoker is 60% less likely than a current smoker to
have coronary heart disease
and 30% less likely to have a stroke.
Smoking is responsible for one third of cancer
deaths and is implicated in 90% of lung cancer
deaths (Cancer in Northern Ireland 1993 - 2001, Cancer Registry
Report 2004).
Smoking is a major cause of subfertility,
with approximately 1200 men aged 30-49 years in the Eastern Board
area suffering sexual impotence because of smoking. Smoking also
damages sperm and reduces sperm quality. Female smokers have a lower
rate of conception and the risk of infertility is doubled. Success
rates for assisted conception techniques are lower for smokers.
The risk of ectopic pregnancy is increased by 250% for female smokers
(BMA – Smoking and Reproductive Life 2004).
Smoking in pregnancy
increases the risk of:
 |
Miscarriage by
25% |
 |
Baby being born dead by 40% |
 |
Death of the newborn by 40% |
 |
Low birth weight by 300% |
 |
Premature birth by 200% |
 |
Foetal malformations (cleft
lip, palate) by 30% |
 |
Placenta praevia by 300% |
Infants who
are born to smokers or are exposed to cigarette smoke are more likely
to have a cot death.
The children
of smokers are more likely to develop middle ear disease, asthma,
respiratory illnesses, impaired growth and development and behavioural
problems (BMA – Smoking and Reproductive Life 2004).
Females who
smoke experience alterations in sex hormones, may develop a male–like
body shape and go through the menopause on average two years earlier
than non-smokers. The risk of developing painful and irregular periods
is also increased.
It is estimated that every cigarette shortens life
by 14 minutes and that 1 in every 2 smokers will die prematurely
as a result of their smoking.
Smoking is the major cause of inequalities
in health and the principal cause of the gap in life expectancy
between the lower and higher socio-economic groups.
Environmental Tobacco Smoke (ETS) is a cause
of lung cancer and in those with long term exposure the risk is
in the order of 20-30%.
