Smoking kills an estimated 15,000 Australians each year(1) and is a leading cause of cancer, heart disease, stroke and emphysema(1, 2). The costs of smoking to Australian society in 2004-05 were estimated to be $31.5 billion(3). Most of us know of the dangers of smoking, but there are still around 2.8 million Australians aged 14 years or older who smoke every day(4).

The Australian Government is committed to reducing the national adult daily smoking rate to 10% and halving the Indigenous adult daily smoking rate by 2018, and helping Australians to improve their health. As part of the National Tobacco Campaign, the Australian Government’s More Targeted Approach Campaign is aimed at high need and hard-to-reach groups. One of these groups is pregnant women and their partners.

The Government has created a national campaign that aims to inform pregnant women, women planning on becoming pregnant, and their partners, about the risks of smoking and the benefits of quitting. The campaign provides information encouraging pregnant women and their partners to quit smoking for good—for their own health and for the health of their unborn child.

Quit smoking and give your baby a healthy start

 1.        SMOKING AND PREGNANCY: THE FACTS

  • In 2009, 14.5% of Australian women, or one in seven, smoked during pregnancy(5).
  • Smoking during pregnancy increases the risk of ectopic pregnancy, miscarriage, premature labour, low birth weight and sudden infant death syndrome (SIDS)(6, 9, 10, 12).
  • Pregnant teenagers are particularly at risk for smoking – 37% of pregnant teenagers reported smoking in 2009(5).
  • In 2010, pregnant women aged under 35 years were more likely to smoke (14%) than those aged 35 years or older (9%)(4).
  • Many women who avoid smoking during pregnancy relapse after the baby is born(7).
  • Social stigma may prevent women from seeking support because they are worried about being judged(7).

2.        MYTH-BUSTING

MYTH: “If I quit cold turkey during my pregnancy it will cause stress to me and my baby.”

FACT: The harsh chemicals in every cigarette deprive a baby of vital nutrients(11). Smoking also cuts down the amount of oxygen and food reaching the baby, while also damaging the mother’s health at a vital time(9, 10). A doctor, midwife or the Quitline (13 7848) can offer advice about better ways to relax or cope with stress.

MYTH: “I know other women who have smoked and have had healthy babies.”

FACT: Smoking during pregnancy poses a huge risk to an unborn child(9). In the womb a baby relies on oxygen in a mother’s blood to breathe and smoking deprives a baby of that oxygen(9, 11). Smoking during pregnancy can lead to complications such as low birth weight and premature birth(6) and cleft lip or palate(8). Once born, the child is more likely to suffer a range of health complications such as, breathing difficulties or sudden infant death syndrome (SIDS)(10, 11). Stopping smoking at any point throughout pregnancy is of benefit(8).

MYTH: “There’s nothing wrong with having a low-weight baby, it just means a quicker and easier birth.”

FACT: There is no evidence that having a low birth-weight baby makes things easier for a mother or their baby. Low birth weight is associated with an increased risk of illness and higher risk of the baby dying at birth or soon afterwards(9).  A small baby can become stressed during labour and make the birth more complicated(10).

MYTH: “I’m already pregnant. There’s no point quitting now, the damage is done.”

FACT: Quitting during pregnancy reduces the risk of harm to the unborn baby(8). However, planning to quit as early as possible can mean a better start to life for a baby(9).  The only safe level of smoking in pregnancy is not smoking at all because any level of nicotine or tobacco smoke exposure increases the risk of adverse effects and the greatest gain in health benefits comes from quitting rather than cutting down(8).

MYTH: “If I cut down on smoking while I’m pregnant that will be enough.”

FACT: There is no safe level of smoking. Smokers who cut down or choose to switch to so called ‘light’ or ‘mild’ cigarettes inhale just as many damaging chemicals(9).

MYTH: “Second-hand smoke won’t affect my unborn child.”

FACT: A woman provides everything her baby needs during pregnancy. Everything she eats, drinks and breathes – including tobacco smoke – affects her and the baby(12). Secondhand smoke causes immediate harm to nonsmokers who breathe it(10). Secondhand smoke exposure during pregnancy can increase the risk of congenital malformations, stillbirths, and possibly other adverse outcomes for the unborn baby(13).

MYTH: “Smoking won’t affect breastfeeding.”

FACT: Breastfeeding has important health benefits for both mothers and babies(9). Breastfeeding women who smoke have lower levels of prolactin than those who do not smoke(9). Prolactin is essential for the initiation and maintenance of milk production(9). Mothers who smoke are more likely to produce less milk and milk of poorer quality(9). Women exposed to second-hand smoke breastfeed for a shorter time(9).

3. TIPS AND ADVICE: HELPING WOMEN TO QUIT

Help is out there, get support. Call the Quitline (13 7848), talk to your doctor and plan a quitting strategy together or visit the Quitnow website at www.quitnow.gov.au. When you feel the urge to light up remember the four Ds(11):

  • Delay:  Delay for a few minutes – the urge will pass
  • Deep breathe: Breathe slowly and deeply
  • Do something else:  Ring a friend or practise your prenatal exercises
  • Drink water: Take ‘time out’ and sip slowly

 

How to stay quit:

  • Gentle exercise such as swimming, walking or yoga will help your body to adjust to being without cigarettes. Always consult your doctor before starting any new exercise program(11).
  • Change your environment – make your home and car smoke free. Ask your partner and friends not to smoke around you. Throw away your cigarettes, lighters and ashtrays(11).
  • Be positive – tell yourself you are coping and reward yourself with the money you have saved by not buying cigarettes.
  • If you are struggling to quit, Nicotine Replacement Therapy (NRT) may help you. You should seek advice and support from your doctor or health professional to work out what is best for you and your baby(8, 11). The main benefits of using NRT are the removal of the other toxins contained in tobacco smoke and the lower dose of nicotine delivered by NRT than tobacco smoke(8).
  • NRT is less harmful than smoking during pregnancy and breastfeeding but make sure you speak to your doctor or midwife to find out what will work best for you(8).

Information for partners:

If your partner smokes and is pregnant you should encourage her to quit. You can have a big influence on her. It’s important that she quits smoking for herself and the baby.

If you smoke it will be harder for her to quit, so you may want to give her some moral support and give up too. If you’re not ready to quit, remember passive smoking is dangerous – babies are not protected from smoke in the mother’s womb(12).  Protect your baby by not smoking inside your home or car, or around your partner. It is also important that after the birth, you do not smoke near your baby(11).

Secondhand smoke exposes a pregnant woman and the unborn baby to the same range of tobacco smoke toxins experienced by active smokers, although at lower levels(13). Tobacco smoke damages the tissues of an unborn baby’s growing brain and lungs(12).

For more information and support on ways to quit call the Quitline 13 7848, visit the website www.quitnow.gov.au, or call your doctor or healthcare professional.

  • so selfish to smoke while pregnant

  • I figure there’s too much else that can go wrong without the possibility of adding to it with smoking….. so try for everyone’s sake to ‘not!’

  • I realise it must be hard to give up, but considering everything we now know about smoking during pregnancy – well, it’s pretty much a no brainer.

  • Smoking is such an addictive thing I have known some women too to smoke throughout pregnancy I guess addiction is hard to give up no matter what it is.

  • If you smoke and want to give up, but say that you can’t, then you obviously don’t think enough of yourself and your worth. If you’re pregnant, you have to love and care enough about your unborn child to find the strength to give up. If you don’t care about yourself, you have to care about your child.

  • An interesting read, full of good information

  • “cutting down’ when pregnant is unfortunately not good enough, although its a great start. Seeing babies suffer horrible medical conditions that are preventable is the most heart breaking thing…and I’m not just a nosy preacher, I smoked heavily for over 15 years, quitting is the best thing you can do for so many reasons!

  • i smoked when i was pregnant i cut right down – i was told my baby would be small, prem, unhealthy and underdeveloped lungs – i had a very healthy 8p 7 bub born right on time 54cms long and lung function is 100% normal. so many people get on their high horse about it – yes its bad i have quit since giving birth. How bout being made at junkies giving birth to drug addicted babies! Years ago most of your parents probably drank and smoked when they were pregnant! There should be support to help people quit not constantly judge them – because everyone is perfect right? you’ve never made a bad decision!

    • There’s plenty of support to help people quit and a heaps of information to help them make informed decisions. Yes, many of our parents did smoke when they were pregnant but that’s no excuse for those who do it now, we’ve come along way since then, have information that they didn’t have. Of course we all make mistakes but there’s no point in continuing to make them once all the facts are on the table. Congratulations on quitting.
