Maternal smoking during pregnancy (MSDP) is a substantial health concern. This is because mothers who smoke during pregnancy jeopardise themselves and their babies by continuing to engage in this addictive behaviour.
Despite overwhelming evidence that maternal smoking is harmful to both the mother and the child’s health, many expectant moms continue to smoke during pregnancy, and the habit persists even after they begin breastfeeding. Aside from active smoking, there is evidence that smelling cigarette smoke while pregnant, also referred to as second-hand smoking or passive smoking, can lead to several medical conditions. Thus, this article addresses the impact of smoking on child development, the significance of quitting smoking, and accessible alternatives for moms to consider.
What does maternal smoking during pregnancy refer to?
Maternal smoking during pregnancy refers to actively smoking while pregnant. This conduct poses serious health risks to both the mother and her baby. It is important to emphasise that smoking is one modifiable risk factor that can have long-term negative effects on respiratory, cardiovascular, and cerebrovascular health. Smoking damages practically all of the body’s organs, and in extreme circumstances, it may even result in several forms of cancer.
Knowing that smoking during pregnancy is socially inappropriate and that it may harm the unborn child causes stress, worry, guilt, and shame in women who smoke during pregnancy.
What is the impact of the mother’s active smoking on herself and her child?
Nicotine, a chemical noted for its neurotoxicity and addictive qualities, is an ingredient in tobacco or cigarette smoke. Pregnant women absorb nicotine from cigarette smoke, and due to its high lipid solubility, both nicotine and its primary metabolite, cotinine, quickly pass through placental tissue and enter the foetal circulation.
Maternal cigarette smoking decreases uterine blood flow and increases uterine resistance. As a result, the foetus is deprived of nutrients and oxygen due to the reduction in blood flow and rise in vascular resistance. Ultimately, this nicotine-induced hypoxia and malnutrition might be disastrous for both the mother as well as her child.
Effects of smoking during pregnancy: For children
The primary markers of foetal growth inhibition caused by maternal smoking are reduced- birth weight, – length, and – head and – chest circumference at birth. Even if the underlying physiological mechanisms causing these negative consequences are not entirely known, MSDP has been associated with:
- Congenital conditions, including heart problems, hearing impairment, gastroschisis, and clubfoot;
- Long-term or disruptive behavioural issues in childhood, including attention deficit and hyperactivity disorder.
- Childhood obesity and increased weight in children
- The adverse outcomes include preterm birth, spontaneous abortion, growth restriction, and an increased risk of SIDS.
Another detrimental influence is the generational transmission of smoking, which raises the risk that offspring may develop a tobacco addiction and begin smoking.
Effects of smoking during pregnancy: For moms to be
Active smoking has a major detrimental impact on the psychological health of pregnant women, as was previously mentioned. Among the other negative consequences are an increased chance of miscarriage, stillbirth, and preterm delivery. Moreover, smoking during pregnancy has been associated with birth abnormalities, childhood obesity, and behavioural problems in children.
Reminding moms that passive or active tobacco smoke exposure might affect not only the development of the foetus but also the immune system of the mother is vital.
In what ways may pregnant women who smoke be helped?
First and foremost, it should be clarified that it is possible to quit the addictive habit of smoking, especially when they learn they are pregnant. Many women decide to cut back on their cigarette use, which is a wise move. The mother and her baby are only shielded from the negative effects of smoking when the mother entirely quits, according to the findings.
Please be advised that pregnant women who reported cutting back on their smoking did not always mean they reduced their exposure to carcinogens, as evidenced by the levels of carbon monoxide (CO) in their bodies. This highlights how critical it is for an expectant mother to completely give up smoking rather than just cutting back.
Addressing the Tobacco Dependence:
Tobacco cigarettes are a rather efficient means to obtain nicotine since cigarette smoke can swiftly enter the body through the respiratory system, buccal mucosa, and epidermis. However, the intestinal tract absorbs very little when given orally. Inhaled nicotine activates the brain over a period of 10–19 seconds, releasing chemicals or substances that ensure sensations of well-being, alertness, and vitality.
When a smoker stops, their body generates fewer of these substances, which causes withdrawal symptoms to start as soon as they quit. Unprepared tobacco users may find them quite distressing. As a result, the tobacco user is trapped in a vicious cycle and is compelled to continue smoking tobacco. For this reason, cigarette smokers require a strategic approach.
This strategy fights tobacco dependence by employing behavioural, nicotine replacement, and non-nicotine replacement therapies.
Behavioural Intervention for Tobacco Addiction:
Patient education and behavioural therapy should be the mainstays of treatment when it comes to helping smokers quit. It should be stressed that the best option for women who smoke during pregnancy is quitting the addictive habit.
Many behaviour therapies have been demonstrated to be effective in helping people quit smoking; these range in complexity from straightforward guidance from doctors or other healthcare professionals to considerably more involved counselling from counsellors.
Brief Advice: This involves urging all tobacco users to quit smoking, which usually takes a few minutes. Usually, this guidance is provided during a scheduled meeting or conversation.
Behavioural support: This refers to assistance provided to individuals in quitting tobacco smoking without the use of prescription drugs. It can encompass any kind of assistance for quitting smoking that disseminates information on tobacco use and quitting, offers encouragement, and imparts skills and techniques for behaviour modification. It takes a specific set of fundamental information, abilities, and competencies to effectively counsel someone to quit smoking.
Any behavioural intervention for tobacco cessation must include the Five As, which stand for Ask, Advise, Assess, Assist, and Arrange, and the Five Rs, which stand for Relevance, Risk, Rewards, Repetitions, and Roadblocks, respectively. Global research has demonstrated the remarkable efficacy of these measures in decreasing tobacco dependence.
Nicotine replacement therapy (NRT):
Pharmacotherapy is an option if behavioural therapy doesn’t work. If so, talk to your doctor about nicotine replacement treatment. Nicotine from cigarettes exposes the mother and child to 4,000 other pollutants in addition to nicotine, making smoking significantly more dangerous than obtaining nicotine from a cleaner, better alternative, or regulated source like authorised NRT solutions.
Nicotine replacement therapy or NRT was officially added to the National List of Essential Medicines (NLEM) by the Indian government on September 13, 2022. The primary forms of nicotine replacement therapy include chewing gum, patches, inhalers, and nasal sprays.
It is essential to firmly prevent women from using tobacco products while they are pregnant or breastfeeding. To treat withdrawal symptoms, it is advisable to ask them to stop smoking and use the behavioural approaches that were previously described. NRT use, however, might be taken into account if behaviour counselling by itself isn’t enough to support them in quitting. Mothers who are expecting or nursing their babies should be advised to use shorter-acting medications to reduce the duration of time the foetus is exposed to nicotine. Nonetheless, NRT might not be able to guarantee the complete cessation of the addictive habit of smoking.
Non – Nicotine Replacement Therapy:
In this type of therapy, medication that works on a comparable set of neurotransmitters to those affected by nicotine is used to effectively manage the addictive behaviour.
This minimises the consequences of withdrawal and addresses the urge or need to use nicotine. When using nicotine replacement therapy (NRT), tobacco users stop using tobacco products right away. When using non-NRT medication, users establish a quit date that occurs one to two weeks after taking the drug. The two main medications used in non-NTR therapy are Bupropion and Varenicline.
Combination Therapy:
Combined behavioural and pharmacological therapy appears to be the most effective approach for addressing tobacco dependency. It is possible to anticipate complementing and possibly additive benefits from these medicines because they function through distinct systems. Hence, nicotine replacement therapies (NRT) combined with supportive counselling are the most widely used and intensively reached treatment modality. Although self-help measures alone minimally improve quit rates, individual and combined pharmacotherapies and counselling, either alone or in combination, can dramatically boost cessation.
Healthy moms assure healthy future generations:
It should be urged not to smoke during pregnancy for mothers who smoke. Tobacco smoke during pregnancy poses significant risks to both the mother and the developing foetus. Research highlights the possible damage to both mother and child caused by exposure to second-hand smoke or a father’s smoking effects on the baby. Smoking cigarettes can expose a baby to dangerous chemicals, which can result in consequences like low birth weight, early birth, and developmental problems. Furthermore, if their parents smoke, children are more likely to start smoking as well.
Therefore, expectant mothers should not smoke during pregnancy and seek support to quit to provide a healthier environment for themselves and their babies which will eventually encourage future generations to be healthier.
