Lifestyle & Behaviour - Smoking


Tobacco

In November 2002, Alan Milburn said, in a public speech that "Smoking is a public health disaster." He went on to outline the measure the government has and will be taking, and what it expected of the NHS in supporting the 70% of smokers who want to quit.

Smoking & ill-health

Nationally, 19% of deaths (120,000 per year) are caused by smoking. One in two regular smokers is killed by tobacco, half dying in middle-age (losing an average of 20 years of life) and half in later life (but still an average of eight years earlier than their non-smoking peers). Smoking Causes:

  • 80% of chronic obstructive pulmonary disease
  • 80% of all cases of lung cancer
  • 30% of all deaths from cancer, including cancer of the mouth, lip, tongue, stomach, lung, liver, pancreas, kidney, bladder, cervix, and leukaemia
  • 90% of peripheral vascular disease (causing 2,000 amputations each year)
  • 17% of cases of coronary heart disease

As coronary heart disease is so common, most deaths caused by smoking are due to coronary heart disease.

Compared with non-smokers, smokers who smoke between 1 and 14 cigarettes a day have eight times the risk of dying from lung cancer and those who smoke more than 25 cigarettes a day have 25 times this risk. Cigarette smokers have two to three times the risk of a heart attack, compared with non-smokers. Smoking also increases the risk of:

  • impotence
  • sperm abnormalities
  • premature menopause
  • spontaneous miscarriage
  • bleeding during pregnancy
  • low birthweight babies
  • Sudden Infant Death Syndrome (cot death)
  • aortic aneurysm
  • stroke
  • peptic ulcers
  • poor wound healing
  • chest infections

Half of all regular smokers die prematurely because of tobacco use, losing an average of 14 years of life.

Effects of secondhand smoke exposure

Breathing other people's smoke causes over a thousand deaths each year in this country from heart disease and a few hundred deaths from lung cancer. Smoking during or after pregnancy causes one in two cot deaths (Sudden Infant Death Syndrome). Infants whose parents smoke have four times the risk of being admitted to hospital with a respiratory infection before their first birthday. Parental smoking increases the risk of middle ear infections in childhood.

For people who already have asthma or coronary heart disease, other people's smoke can precipitate severe symptoms.

Cigarette smoking
Who smokes?

There are large differences in smoking prevalence and consumption in the UK, varying by age, sex, social class, employment status, and ethnicity. People in deprived circumstances are not only more likely to take up smoking but generally start younger, smoke more heavily and are less likely to quit smoking , each of which increases the risk of smoking-related disease. About 12 million adults in the UK smoke cigarettes - 28% of men and 26% of women. There has been a large fall over past decades through established smokers quitting but almost as many young people are taking up smoking as previously.

More than 80% of smokers take up the habit as teenagers: about 450 children in the UK start smoking every day. Smoking is highest among those aged 20-34, of whom 37% of men and women. Smoking prevalence gradually declines with age, through quitting or dying; the lowest smoking rate is among people aged 60 and over, of whom 17% smoke. About one fifth of Britain's 15 year-olds - 19% of boys and 25% of girls - are regular smokers (at least one cigarette per week), despite the fact that it is illegal to sell cigarettes to children aged under 16.

Men and women in manual socio-economic groups are more likely to smoke than people in non-manual occupations. 21% of men and 18% of women in the professional and managerial groups smoke compared with 35% of men and 31% of women in routine and manual groups.

There are 2.9 million London residents who are members of black and minority ethnic groups. The Health Survey for England published in 2000 found that 27% of men were current smokers, 31% used to smoke regularly and 42% had never smoked regularly. The age-adjusted risk ratio for being a current smoker was 1.26 for black Caribbean men, 1.43 for Irish men and 1.57 for Bangladeshi men, compared with the general population. Chinese (0.62), Indian (0.78) and Pakistani men (0.90) were less likely than the general male population to smoke. Although smoking prevalence among women was the same (27%) in the general population, the picture was very different among ethnic groups. Irish women were the only group reported who were more likely to smoke than average (age-adjusted risk ratio 1.16), with slightly fewer smokers among black Caribbean women (0.85) and very few among other women (Bangladeshi 0.07, Pakistani 0.14, Indian 0.19+, and Chinese 0.31).

The Department of Health commissioned a questionnaire survey of just under 10,000 pupils in 321 schools in England in the 2002 Autumn term. The survey is the most recent in a series that began in 1982.

  • Prevalence of regular smoking (at least one cigarette a week) has remained :stable, at between nine percent and 11% since 1998 and has been 10% since 2000;
  • There is a sharp increase in prevalence of smoking with age:1% of 11-year-olds smoke regularly compared with 23% of 15-year-olds.
  • As in previous years, overall girls are more likely to be regular smokers than boys -11% compared with nine percent;
  • The overall higher prevalence of smoking for girls than for boys was not found amongst 11- and 12-year-olds, but only amongst pupils aged 13 years or more. Smoking was reported by 18% of 14-year-old girls and 26% of 15-year-old girls, compared with 13% of 14-year-old boys and 21% of 15-year-old boys.

The government set a target in the Smoking Kills White Paper to reduce the prevalence of smoking among young people aged 11-15 from a baseline of 13% in 1996 to 11% by 2005 and nine percent or less by 2010.

Smoking and inequalities

Smoking is the principal proximal cause of health inequalities in the UK, particularly for CHD, other cardiovascular and respiratory diseases, and cancers. Adult men of working age in social class V are three times as likely to die of lung cancer as men in social class I. Women in social class V are almost twice as likely to die of lung cancer as women in social class I.

Benefits of smoking cessation

Smoking cessation is the most important lifestyle factor in reducing mortality, morbidity, and health inequalities over the next 20 years. It is seldom "too late" to stop smoking. Within 15-20 years of stopping smoking, the risk of lung cancer is almost the same as the risk for people who have never smoked. The reduction in risk for CHD is particularly rapid, with the risk falling within a year or so. Encouraging cessation among adults is also important in reducing smoking role models for children.

Community based services supporting smoking cessation in each health authority area in England and Wales, particularly for low-income groups and Black and minority ethnic groups, were mapped in 2000. Although all the NHS services are available to any smoker who wishes to quit, most services had identified as their priority target groups people living on a low income, pregnant women, young people, and heavily dependent smokers.

Secondhand smoke exposure

Restricting smoking in public places is another important target. Reducing exposure to secondhand smoke not only reduces deaths, disease and disability caused by such exposure but also, like decreasing smoking prevalence, reduces the perception among young people that smoking is a normal adult habit.

Ventilation is not the answer. Only 15% of secondhand smoke is particles, which are cleared by filters. The remaining 85% is gaseous: to clear this requires so many changes of air per hour that customers or employees would notice a pronounced draught. It would also use very large amounts of electricity and be very expensive.

In 2001, SmokeFree London commissioned a survey of 10,000 Londoners' behaviours and attitudes regarding smoking. It provided a picture of Londoners' smoking habits and their views about smoking, including cessation attempts, exposure to secondhand smoke, attitudes to smoking in public places and to those who sell cigarettes to children, experience of buying smuggled cigarettes and knowledge of the risks associated with tobacco and of the services available to help smokers quit.

An analysis for London as a whole and for the local authority areas was published and distributed October 2001 (SmokeFree London: Survey report ); the results for all London were also published in May 2002 (Attitudes to smoking in the capital ) as a volume in the Tobacco in London series of publications.

Policy context

The 1998 White Paper, Smoking Kills, promoted (for the first time by a UK government) a comprehensive tobacco control strategy. This included:

  • a ban on tobacco advertising;
  • increases in tobacco tax;
  • mass media health promotion campaigns;
  • enforcement on under-age sales;
  • rules on cigarette vending machines;
  • an Approved Code of Practice on smoking in the workplace; and
  • new NHS services to help smokers give up.

Smoking cessation support

Department of Health guidance, initially to Health Action zones, then to all health authorities (and now primary care trusts, PCTs) was to develop a three tier cessation service, comprising brief interventions, 'intermediate' level 1:1 interventions, and specialist cessation services, including clinics. The Acheson report on inequalities also recommended policies to improve living standards for those on low incomes; providing nicotine replacement therapy on prescription as a cessation aid; and support for cessation as ways of encouraging smokers to quit and to remain ex-smokers.

NHS targets

A series of National Service Frameworks and similar documents refer to reducing smoking prevalence amongst:

  • manual groups (NHS Cancer Plan Target: to reduce smoking rates among manual groups from 32% in 1998 to 26% by 2010, in order to narrow the health inequalities gap)
  • patients with existing coronary heart disease (CHD) (CHD NSF - Standard 3)
  • people at high risk of developing CHD (CHD NSF - Standard 4)
  • people in the general population (CHD NSF - Standard 2)
  • adults with diabetes (Diabetes NSF - Standard 4)

The NHS is required to contribute to the national inequalities targets by delivering a one percentage point reduction per year in the proportion of women continuing to smoke throughout pregnancy, focussing especially on smokers from disadvantaged groups.

The 2003 - 2006 Priorities and Planning Framework requires PCTs to:

  • Reduce substantially the mortality rates from the major killer diseases by 2010: from heart disease by at least 40 % in people under 75; from cancer by at least 20% in people under 75 (Objective II, no 6).
  • By 2010 reduce inequalities in health outcomes by 10% as measured by infant mortality and life expectancy at birth (Objective II, no 11)
  • Deliver a one percentage point reduction per year in the proportion of women continuing to smoke throughout pregnancy, focussing especially on smokers from disadvantaged groups as a contribution to the national target to reduce by at least 10% the gap in mortality between "routine and manual" groups and the population as a whole by 2010, starting with children under one year.

Protection from secondhand smoke

Issues of secondhand smoke exposure and the right of employees to smokefree workplaces are gaining prominence. A draft Approved Code of Practice for employers to protect their staff from secondhand smoke has been widely supported by trades unions, environmental health officers, and health professionals but its passage through government has been delayed repeatedly, due to concern about bureaucracy for businesses. The tobacco industry has actively obfuscated the arguments about the hazards of secondhand smoke and has promoted ventilation as the answer in the hospitality industry, despite evidence of its lack of effectiveness in protecting staff or the public from tobacco smoke's toxic chemicals.

In April 2003, a joint conference organised by ASH (Action on Smoking and Health), the TUC, and the Chartered Institute of Environmental Health on protecting employees from secondhand smoke in the workplace was held. In July 2003, the Chief Medical Officer for England included a chapter on secondhand smoke in his 2002 Annual Report. He called for comprehensive workplace smoking bans to reduce smoking prevalence as well as to protect people from secondhand smoke. The same week, British Medical Association called for legislation to require smoke-free public places; a National Opinion Poll found a majority of the public in favour of banning smoking even in pubs; and a television campaign was launched to warn parents of the dangers to children and infants of secondhand smoke.

Other tobacco use
Cigar & pipe smoking

Cigar and pipe smoking increase the risk of oral cancers. Early studies found much lower risks of other health consequences than were shown for cigarette smoking. This resulted in many cigarette smokers switching to smoking cigars or pipes. More recent studies have shown substantial risks of lung and other cancers and circulatory diseases in cigar and pipe smokers. This is probably because former cigarette smokers continue to inhale when they change from cigarettes to smoking other products.

Oral tobacco use - Chewing tobacco

Smoking tobacco, which is chewed alone or with betel quid/paan, has a significant detrimental impact on the oral cavity. It has been recognised that the areca nut, an active ingredient in betel quid / paan, causes oral submucous fibrosis. This is a debilitating, non-reversible and pre-cancerous disease characterised by a stiffening of the oral mucosa and development of fibrous material that restricts mouth opening. The use of smokeless tobacco is known to induce wrinkled changes in the oral mucosa, so-called "snuff dipper's pouches" that occur beneath the lip that can lead to severe gum recession and bone loss. Serious changes can occur in people who have used smokeless tobacco for only a short period of time, and though stopping can alleviate the wrinkling, damage to gums and bone is permanent.

There have been a number of investigations into the implications of smokeless tobacco on South Asian populations in the UK, the majority of which show that betel chewing is prevalent in many areas.
