Smoking cessation in pregnancy

Risk factors for spontaneous preterm delivery

BACKGROUND

There is a substantial variation in rates of preterm delivery between different parts of the world. The understanding of these variations, as well as the biological mechanisms behind spontaneous preterm delivery, is limited. Although the benefit of antenatal interventions has been shown to be limited, using well-known risk factors for spontaneous preterm delivery to select the correct pregnant women for targeted interventions is important from both a medical and caregiving perspective.

OBJECTIVE

To provide an introduction to a substantial research area dealing with risk factors of spontaneous preterm delivery.

METHODS

Risk factors in this review were classified as demographical, obstetrical, and gynecological and those related to the current pregnancy according to high-quality evidence of recent literature.

RESULTS AND CONCLUSION

An introduction to a substantial research area in maternal and fetal medicine was provided that might help clinicians to better understand the risk factors related to preterm delivery and select the correct pregnant women for targeted interventions.

The Great Disrupter: Relationship of Alexithymia to Emotion Regulation Processes and Smoking among Pregnant Women

Background: Many women continue to smoke during pregnancy, despite known risks, often in response to negative affect. Recent scholarship has begun to examine factors that decrease the success of behavioral treatments for smoking cessation in pregnancy, which are the preferred interventions. Alexithymia is one factor that may interfere with smoking cessation interventions. Alexithymia restricts access to emotional information and increases propensity toward maladaptive behaviors, including smoking. However, mechanisms underlying such effects are largely unknown. Objectives: Using data from a longitudinal treatment study, the present research examined difficulties with emotion regulation as a potential mechanism linking alexithymia and smoking. Pregnant smokers (n = 73; mean age = 24.78; SD = 4.50) completed measures related to alexithymia, smoking, emotion regulation, depression, anxiety, and anger at baseline and then again following eight sessions of Cognitive-Behavioral Smoking Cessation Treatment. Results: Nearly 40% of the sample met the criteria for alexithymia. The alexithymia group reported higher depression, anxiety, and anger. They also reported more difficulties with emotion regulation. In a path analysis, baseline alexithymia had a significant positive indirect effect on number of cigarettes smoked at the end of treatment through difficulties with emotion regulation. Conclusions/Importance: Similar to other studies, alexithymia limits the understanding of emotional information necessary for selection and implementation of adaptive coping responses. Our results extend the literature by suggesting that smoking may be an attempt to manage undifferentiated and unpleasant sensations created by alexithymia.

A Pragmatic Guide for Smoking Cessation Counselling and the Initiation of Nicotine Replacement Therapy for Pregnant Aboriginal and Torres Strait Islander Smokers

Smoking prevalence of pregnant Aboriginal and Torres Strait Islander women is quadruple that of pregnant women in the Australian population, and is associated with significant adverse outcomes in pregnancy. While cessation is a priority, there is as yet little evidence for effective interventions. This paper provides a pragmatic approach to addressing the complexities of smoking in pregnant Aboriginal and Torres Strait Islander peoples and informs clinicians about the initiation of nicotine replacement therapy (NRT) in pregnancy. Experts agree that nicotine replacement is safer than continuing to smoke in pregnancy. Although a pharmacotherapy-free attempt is initially recommended, if abstinence is not able to be achieved in the first few days, the women should be offered an accelerated option of NRT starting with oral forms and then, if required, progressing to nicotine patch or combined oral and transdermal therapy. Support should be offered for at least 12 weeks and post-partum. Offering counselling and cessation support to partners and family is also important, as is linking the woman in with appropriate social and community support and Aboriginal specific services. As long as oral forms of NRT are not included in the Pharmaceutical Benefit Scheme for Aboriginal and Torres Strait Islander women a significant and inequitable barrier will remain.

Jumping the Hurdles for Smoking Cessation in Pregnant Aboriginal and Torres Strait Islander Women in Australia

Tobacco smoking perpetuates the disadvantages experienced by Aboriginal and Torres Strait Islander people in Australia. Tobacco smoking is a risk factor for poor maternal and infant outcomes in pregnancy. Over half of Aboriginal and Torres Strait Islander women smoke during pregnancy and few successfully quit. Aboriginal and Torres Strait Islander women face many intrinsic barriers to quitting such as low socioeconomic disadvantage and patterns of use in family networks. There are also several extrinsic hurdles surrounding current practice guidelines and policy that may limit success in reducing smoking rates among Aboriginal and Torres Strait Islander women during pregnancy: the use of the Stages of Change (SOC) model; delay in the use of nicotine replacement therapy (NRT); and the absence of subsidised intermittent NRT. A more proactive approach towards smoking cessation for pregnant Aboriginal and Torres Strait Islander women may be necessary, including moving away from the SOC model approach and subsidised provision of intermittent NRT. Comprehensive programs that take into account the family network and wider social context are also recommended.
