Exposure to active and passive smoking among Greek pregnant women

Practices of pregnant women regarding tobacco and alcohol use during pregnancy at one primary health care clinic in Southern Namibia

Tobacco and alcohol use during pregnancy has negative consequences, to the fetus. The study purpose was to investigate the practices of pregnant women regarding the use of tobacco and alcohol during pregnancy. A quantitative research approach with a descriptive, cross-sectional, analytical design was used. The population were all pregnant women aged 18 years and above attending antenatal care at Mariental clinic. Written informed consent was obtained from all respondents prior to data collection. Data was collected from 211 respondents selected through a systematic sampling. Data was analysed using Statistical Package of the Social Sciences version 27. Descriptive statistics were used for frequencies and percentages. Fisher's Exact test at 0.05 alpha level was used to determine the association between variables. The mean age was 28.8 with a standard deviation of 6.9 years. Most participants, 92 (43.6%) were aged between 18 and 24 years. Majority, 186 (88.15%) were in third trimester of pregnancy and 154 (73%) were single. Most 148 (70.14%) respondents have good practices towards alcohol use during pregnancy. Moreover, 190 (90%) of the respondents were classified as having good practices towards tobacco use in pregnancy. Educational levels showed a significant association with practices towards tobacco smoking (P=0.042). The study concluded good practices among pregnant women on alcohol and tobacco smoking during pregnancy. It is recommended that health facilities should introduce awareness campaign on the dangers of alcohol and tobacco use during pregnancy. Moreover, educational materials should be developed in local languages and distributed to community.

Maternal tobacco, alcohol and caffeine consumption during the perinatal period: A prospective cohort study in Greece during the COVID-19 pandemic

INTRODUCTION

Low-level knowledge of problematic substance use during the perinatal period may lead to numerous adverse outcomes. We sought to determine maternal tobacco, alcohol and caffeine consumption during the perinatal period during the COVID-19 pandemic.

METHODS

This prospective cohort study recruited women from five Greek maternity hospitals between January and May 2020. Data were collected with a structured questionnaire initially completed by postpartum women during their hospitalization and re-administered via telephone interview in the first, third and sixth month postpartum.

RESULTS

The study sample consisted of 283 women. Smoking rates decreased during pregnancy (12.4%) compared to the pre-pregnancy period (32.9%, p<0.001) and during lactation (5.6%) compared to the antenatal period (p<0.001). The smoking rate increased again after breastfeeding cessation (16.9%) compared to the rate during lactation (p<0.001), but remained lower than the pre-pregnancy rate (p=0.008). Only 1.4% of the women reported breastfeeding cessation due to smoking, whereas those who smoked more during pregnancy were more likely to cease breastfeeding (OR=1.24; 95% CI: 1.05-1.48, p=0.012). Regarding alcohol consumption, it was significantly lower during pregnancy (5.7%), lactation (5.5%) and after breastfeeding cessation (5.2%) compared to the pre-pregnancy period (21.9%, p<0.001 for all correlations). Women who consumed alcohol during lactation were less likely to wean (OR=0.21; 95% CI: 0.05-0.83, p=0.027). Caffeine intake decreased during pregnancy compared to preconception period (p<0.001), while in lactating women it remained at low rates until the 3rd month of follow-up. Caffeine consumption at one month postpartum (β=0.09; SE=0.04, p=0.045) was positively associated with longer duration of breastfeeding.

CONCLUSIONS

Tobacco, alcohol and caffeine consumption decreased in the perinatal period compared to the preconception period. The pandemic may have contributed to the downtrend in smoking and alcohol consumption due to COVID-related restrictions and fear of potential illness. Nevertheless, smoking was associated with reduced duration of breastfeeding and breastfeeding cessation.

Factors Associated with Breastfeeding Initiation and Duration in Greece: Data from the Hellenic National Nutrition and Health Survey

Despite its well-documented benefits, breastfeeding rates and duration worldwide do not meet the recommended goals set by the World Health Organization. Data on infant feeding, socio-demographic, lifestyle and perinatal factors were used from 490 mothers (and 958 children), participants at the Hellenic National Nutrition and Health Survey between 2013−2015. Clustered multiple logistic regression and multilevel mixed-model regression analyses were performed to identify factors associated with breastfeeding initiation and duration, respectively. Maternal lower education [Odds Ratio (OR): 2.29, 95% Confidence intervals (95% CI): 1.30−4.04; p = 0.004], smoking during pregnancy (OR: 3.08, 95% CI: 1.64−5.77; p < 0.001), caesarean section (OR = 3.26, 95% CI: 1.83−5.83; p < 0.001), prematurity (OR = 2.74, 95% CI: 1.40−5.37; p = 0.003) and higher birth order (OR = 1.30, 95% CI: 1.04−1.62; p = 0.020) were associated with increased odds of not initiating breastfeeding. Living in rural areas [beta coefficient b = −27.93, p = 0.043], smoking during pregnancy (b = −64.47, p < 0.001), caesarean section (b = −28.76, p = 0.046) and prematurity (b = −46.67, p = 0.048) were significantly associated with shorter breastfeeding duration. Children born chronologically closer to the survey were more likely to breastfeed and for longer periods. Educational promotion and enhancement of breastfeeding awareness that account for maternal exposures are required. Prevention of prematurity and avoidance of unnecessary caesarean section is crucial, while additional breastfeeding support is needed when preterm birth occurs, or caesarean section cannot be avoided.

Barriers to Smoking Cessation and Characteristics of Pregnant Smokers in Greece

Objectives: Nicotine addiction and the inability of a large part of pregnant smokers to quit is one of the main preventable causes of morbidity and mortality during the perinatal period. The aim of this study is to investigate nicotine dependence and overall smoking habits of pregnant smokers and to possibly correlate them with smokers' social and demographic characteristics. Materials and methods: One hundred and fourteen pregnant smokers answered an electronic questionnaire consisting of 59 questions, which was divided into six sections. The questionnaires were filled out by participants from many regions of Greece and Cyprus. Results:Before their pregnancy, women smoked 19 cigarettes per day on average, while during their pregnancy they dropped to eight cigarettes per day; 65.8% of respondents stated that their husband smoked, while 58.8% answered that they had been exposed to secondhand smoke; 13.2% of pregnant smokers stated that they had had depression at some point in their lives and 14.9% reported having undergone domestic violence; 55.3% of respondents acknowledged that smoking was responsible for a variety of adverse effects to the fetus; and 97.4% of pregnant women did not follow a smoking cessation counseling program, compared to just 2.6% who did. Conclusions:The pregnant smokers in our study did not have appropriate information about the available smoking cessation services, which were not generally considered to be useful for them, and consequently they did not utilize cessation assistance. The resistance towards quitting smoking, which was observed in the sample, may also be attributed to the lack of specialized smoking cessation services in maternity hospitals in Greece.

Assessment of the Relationship Between Smoking and Depression in Pregnant Women

Smoking during pregnancy has negative effects on both maternal and fetal health. One of these negative maternal effects is the potential for depression. A high rate of cigarette smoking in pregnancy is an important public health issue since it affects not only the pregnant woman but also the newborn and its healthy development. The aim of this study is to investigate the relationship between smoking, influencing factors, and depression prevalence in pregnant Syrian refugees and pregnant citizens of the Republic of Turkey (TR). Pregnant citizens in the TR and pregnant Syrian refugees who were registered at health centers between 15.04.2017 and 15.10.2017 in the border city of Ceylanpınar in the Province of Şanlıurfa in Syria were visited in their living areas in the district center and at a tent village, respectively. A total of 414 pregnant women agreed to participate in the study and were included in the survey. To collect data for the cross-sectional study, a sociodemographic and pregnancy characteristics questionnaire was used, in addition to the Fageström Test for Nicotine Dependence (FTND) and the Beck Depression Inventory (BDI). The rate of smoking in all pregnant women was determined to be 49.3% (n = 204) before pregnancy and 37.9% (n = 157) during pregnancy. A statistically significant difference was found between age groups and educational status in relation to smoking status (p = 0.005, p = 0.001). There was also a statistically significant difference between the smoking status of pregnant women and that of their partners and family members (p = 0.001, p = 0.002). The percentage of pregnant women who were passive smokers was 80.2% (n = 332), and a statistically significant difference was found between passive smoking and smoking status (Fisher; 0.000). The presence of risk for depression was detected in 49.8% (n = 206) of all pregnant women surveyed; the rate of depression risk was 50.5% (n = 104) in pregnant TR citizens and 49.5% (n = 102) in pregnant refugees, with no significant difference between the two groups. There was a statistically significant difference between smoking status in pregnancy and the presence of depression risk (p = 0.001). 32.5% of pregnant women were highly nicotine dependent. A moderate positive correlation was determined between the FTND and BDI scores of pregnant women (r = 0.346; p = 0.001). It was found that one-third of all pregnant women smoked and that one of every two showed a risk for depression. A statistically significant correlation was found between smoking status and risk for depression. No statistically significant difference was determined between the two groups, despite high levels of smoking, nicotine dependence, and depression in both. These data suggest the need to develop new preventive strategies in regard to smoking among pregnant women.

A single-center, prospective, observational study on maternal smoking during pregnancy in Greece: The HELENA study

INTRODUCTION

The unequivocal association between exposure to smoke and numerous complications of pregnancy, demonstrated in the last decades, has led to a significant decrease of smoking rates in pregnancy. The aim of the present study was to determine the prevalence of maternal smoking and to elucidate factors predisposing to it among pregnant women in Athens, Greece.

METHODS

A population of 1700 pregnant women (mean age: 31.2±5.5 years) who visited consecutively the Cardiology Department of Helena Venizelou Maternity Hospital in Athens, Greece, between September 2016 and August 2017, was prospectively analyzed. Data regarding changes in the future mother’s smoking habit as well as different sociodemographic factors potentially related to these changes were recorded.

RESULTS

Of the 1700 participants, 704 (41.4%) were smokers, and of those 52.4% quit smoking after knowledge of their pregnancy status. The overall prevalence of smoking in pregnancy was 19.7%. Prevalence was higher in women who were aged <20 years (p=0.038), were multipara (p=0.032), had ≤12 years of education (p=0.044) and had a partner who was a smoker (p=0.047). Women aged ≤20 years were more likely to be persistent smokers at the beginning of pregnancy and demonstrated a higher prevalence of smoking during pregnancy (42.2% vs 19.7% in the overall study population).

CONCLUSIONS

Our data demonstrate that maternal smoking during pregnancy still remains a major public health issue in Greece with a prevalence higher than most other industrialized countries.

Inadequate Knowledge, Attitude and Practices about Second-Hand Smoke among Non-Smoking Pregnant Women in Urban Vietnam: The Need for Health Literacy Reinforcement

The rate of exposure to second-hand smoke (SHS) is relatively high in several countries, including Vietnam, and health issues related to SHS have worsened in recent years, especially for pregnant women and their infants. Enhancement of knowledge, attitude, and practice (KAP) scores of pregnant women in Vietnam could raise practical interventions to protect their health and reduce complications of SHS. A cross-sectional study of 432 pregnant women who came to the Obstetrics Department of Bach Mai Hospital, Hanoi, Vietnam for antenatal care was conducted in 2016 to collect information about their KAP related to SHS. Composite mean scores from survey questions assessing their KAP were calculated on a 10-point scale, finding mean scores of 4.19, 7.45, and 4.30, respectively. Higher scores indicated better knowledge, attitude, and practice. Generalized linear models identified that age, occupation, living place, and sources of information were associated with SHS-related KAP. Findings from this study indicate that suitable programs related to SHS should be implemented to improve and reinforce health literacy to both mothers and smokers to reduce the harmfulness of smoking on women and their infants' health.

Smoking cessation in pregnancy: An update for maternity care practitioners

INTRODUCTION

This paper provides an up-to-date summary of the effects of smoking in pregnancy as well as challenges and best practices for supporting smoking cessation in maternity care settings.

METHODS

We conducted a qualitative review of published peer reviewed and grey literature.

RESULTS

There is strong evidence of the effects of maternal tobacco use and secondhand smoke exposure on adverse pregnancy outcomes. Tobacco use is the leading preventable cause of miscarriage, stillbirth and neonatal deaths, and evidence has shown that health effects extend into childhood. Women who smoke should be supported with quitting as early as possible in pregnancy and there are benefits of quitting before the 15th week of pregnancy. There are a variety of factors that are associated with tobacco use in pregnancy (socioeconomic status, nicotine addiction, unsupportive partner, stress, mental health illness etc.). Clinical-trial evidence has found counseling, when delivered in sufficient intensity, significantly increases cessation rates among pregnant women. There is evidence that the use of nicotine replacement therapy (NRT) may increase cessation rates, and, relative to continued smoking, the use of NRT is considered safer than continued smoking. The majority of women who smoke during pregnancy will require support throughout their pregnancy, delivered either by a trained maternity care provider or via referral to a specialized hospital or community quit-smoking service. The 5As (Ask, Advise, Assess, Assist, Arrange) approach is recommended for organizing screening and treatment in maternity care settings. Additionally, supporting smoking cessation in the postpartum period should also be a priority as relapse rates are high.

CONCLUSIONS

There have been several recent updates to clinical practice regarding the treatment of tobacco use in pregnancy. It is important for the latest guidance to be put into practice, in all maternity care settings, in order to decrease rates of smoking in pregnancy and improve pregnancy outcomes.

Continued smoking versus spontaneous quitting among pregnant women living in a high risk environment

OBJECTIVES

In Hungary, 37% of women living in poverty were smokers in 2012. There are no valid data of pregnant women's spontaneous smoking cessation.

METHODS

Our retrospective cohort study (2009-2012) targeted the most underdeveloped regions with an estimated 6-8.5% of Roma population. The sample (N = 12,552) represented 76% of the target population i.e. women in four counties in a year delivering live born babies. Chi-square probe and multivariable logistic regression model (p < 0.05) were used to assess relationship between socio-demographic characteristics and spontaneous cessation.

RESULTS

Prior to pregnancy, the overall smoking rate was 36.8%. That of women in deep poverty and Roma was 49.7% and 51.1%, respectively. 70.3% of smokers continued smoking during the pregnancy. Among them 80.6% lived in deep poverty. Spontaneous quitting rate was 23.0%. Factors correlated with continued smoking included being Roma (OR = 1.95), undereducated (OR = 2.66), living in homes lacking amenities (OR = 1.48), and having regularly smoking partner (OR = 2.07). Cessation was promoted by younger age (≤ 18 years) (OR = 0.18), being married (OR = 0.50), and the first pregnancy.

CONCLUSIONS

Tailored cessation programmes are needed for Roma, older, low-income, and multiparous women who are less likely to quit on their own. Engaging husbands/partners is essential to reduce smoking among pregnant women and second-hand smoke exposure.

Exposure to secondhand smoke in Iranian pregnant women at home and the related factors

INTRODUCTION

Fetus health is of high importance in pregnant women and exposure to secondhand smoke (SHS) endangers maternal and fetal health. Therefore, in this study we examined the prevalence of exposure to SHS in pregnant women at home and the related factors.

METHODS

This cross-sectional study was conducted with 255 pregnant women who were referred to the Isfahan health care center from July to September 2018. A questionnaire that was designed by the research team was applied to collect data about the participants' prevalence of exposure, attitude-emotional dimension, perceived susceptibility, perceived severity, and perceived barriers. The questionnaire used was self-administered. The validity and reliability of the questionnaire were confirmed by a panel of experts. Cronbach's alpha of attitude-emotional dimension, perceived susceptibility, perceived severity, and perceived barriers were also calculated as 0.81, 0.91, 0.92, and 0.89, respectively. Statistically significant differences were examined using chi-squared test and Mann-Whitney test.

RESULTS

We found that the prevalence of exposure to SHS in pregnant women was 23.1%. The age of the husband (p=0.041), education level of the smoking husband (p=0.005), the education level of the pregnant woman (p=0.002), employment status of husband (p=0.010), and whether the pregnancy was planned (p=0.010) had significant association with the participant prevalence of exposure to SHS. Thus, older age of husbands, lower education levels of husbands and wives, unwanted pregnancies, and unemployment of husbands resulted in higher exposure to SHS. The mean scores of knowledge and perceptions were lower in women exposed to smoke than in non-exposed women (p<0.05).

CONCLUSIONS

The rate of SHS exposure was high in pregnant women. The knowledge and perception scores of exposed women to SHS were lower than those of non-exposed women. Low levels of education of husbands and women, unemployment and higher age of husbands, and unwanted pregnancies were considered as health risk factors. Therefore, effective training programs should be designed to educate pregnant women and their husbands.

The effect of prenatal smoke exposure on child neuropsychological function: a prospective mother-child cohort study

Objective: To study prospectively the effect of prenatal smoke exposure (PSE) on child neuropsychological function and intelligence quotient (IQ).Background: PSE has been associated with adverse effects on child neurodevelopment. However, some studies reported that these associations disappear after adjustment for potential confounders.Methods: A cohortof 248 mothers-child dyad was followed from the first trimester of pregnancy until children were 7.5 years old. PSE was recorded during pregnancy by questionnaire and plasma cotinine. The Wechsler Intelligence Scale for Children, the Neuropsychological Assessment of Executive Functions for Children (ENFEN) and the School Neuropsychological Maturity Questionnaire were administered at 7.5 years of age. The effect of PSE on child IQ and neuropsychological function was assessed with ANCOVA, adjusting for obstetric, neonatal and sociodemographic factors.Results: Children whose mothers smoked throughout pregnancy scored lower in interference (ENFEN) compared to unexposed children (F = 4.1; p = .008). The results showed no differences in other executive functions, verbal and visual memory and IQ between the PSE groups.Conclusion: PSE had little effect on child neuropsychological outcome and was limited to mental flexibility. Nevertheless, these findings support further efforts aimed at encouraging mothers to quit smoking in pregnancy.

Epigenetic impacts of maternal tobacco and e-vapour exposure on the offspring lung

In utero exposure to tobacco products, whether maternal or environmental, have harmful effects on first neonatal and later adult respiratory outcomes. These effects have been shown to persist across subsequent generations, regardless of the offsprings' smoking habits. Established epigenetic modifications induced by in utero exposure are postulated as the mechanism underlying the inherited poor respiratory outcomes. As e-cigarette use is on the rise, their potential to induce similar functional respiratory deficits underpinned by an alteration in the foetal epigenome needs to be explored. This review will focus on the functional and epigenetic impact of in utero exposure to maternal cigarette smoke, maternal environmental tobacco smoke, environmental tobacco smoke and e-cigarette vapour on foetal respiratory outcomes.

Association of secondhand smoke and depressive symptoms in nonsmoking pregnant Women: A systematic review and meta-analysis

BACKGROUND

Globally about 30% of adult women and 40% of children are exposed to secondhand smoke (SHS) from active smokers. SHS exposure of pregnant women has been associated with postpartum depression. Unexposed women in pregnancy had lower rates of postpartum depression than women exposed to SHS. This systematic review aimed to determine the association of depressive symptoms and exposure to SHS in nonsmoking pregnant women.

METHOD

The case-controlled, cross-sectional, and cohort studies with a comparison group were included. Studies including women who had smoking history during pregnancy were excluded. The comprehensive electronic databases, CINAHL, EMBASE, and Medline were searched.

RESULT

Of the 2777 records screened, seven studies were included in the review for data extraction. The bias of studies was assessed using the RoBANS. We synthesized two studies that showed depressive symptoms at any time during pregnancy and postpartum significantly increased (ORs = 1.77 [95% CI = 1.12 - 2.79]; p = 0.01; I²= 28%, 4103 women, two studies), and significantly increased the odds of antenatal suicidal ideation in SHS exposed women (ORs = 1.75 [95% CI = 1.14 - 2.70]; p = 0.01; I²= 51%, 2670 women, two studies). Lack of studies from counties with the highest smoking rates was a limitation.

CONCLUSIONS

SHS exposure during pregnancy showed a significant increase in the odds of depressive symptoms. Furthermore, research is required to clarify to association between SHS and depression.

Counselling for smoking cessation during pregnancy reduces tobacco-specific nitrosamine (NNAL) concentrations: A randomized controlled trial

INTRODUCTION

Smoking cessation during pregnancy is beneficial to both the mother and child. Our objective was to assess if an intensive smoking cessation intervention for pregnant women increases: a) rates of smoking cessation, and b) reduces exposure to tobacco-specific carcinogens during pregnancy.

METHODS

A two-group single-blinded parallel randomized controlled trial (RCT) was conducted involving 84 pregnant smokers in either a high intensity (n=42) or minimal contact control group (n=42). Women assigned to the high intensity smoking cessation intervention group received a single 30-minute behavioural counselling session and a tailored self-help booklet. The primary outcome measures were: 7-day point prevalence abstinence measured by selfreport and urine cotinine levels, and maternal tobacco specific carcinogens nitrosamine (NNAL) urine concentrations assessed at 32 weeks of gestation.

RESULTS

A significantly greater percentage of pregnant smokers quit smoking in the high intensity group compared to the low intensity control group (45.2% vs 21.4%; p=0.001). A significant decrease in urine cotinine concentrations was documented in the experimental group (-140.74 ± 361.70 ng/mL; p=0.004), with no significant decrease documented in the control group. A significant decrease in NNAL levels was also documented in the experimental group (158.17 ± 145.03 pg/mL before, 86.43 ± 112.54 pg/mL after; p=0.032) with no significant changes in the control group.

CONCLUSIONS

The high intensity intervention tested resulted in significantly greater cessation rates. Intensive smoking cessation interventions can be effective in reducing fetal exposure to NNAL. This is the first trial to report on NNAL tobacco-specific carcinogen concentrations before and after an intervention for smoking cessation during pregnancy.

Passive smoking and postpartum depression among Chinese women: A prospective cohort study in Tianjin, China

Smoking has been associated with depression in the general population. Whether passive smoking is also associated with postpartum depression (PPD) is uncertain. From 2010 to 2012, we recruited 8,842 pregnant women in Tianjin, China. The mainland Chinese version of the Edinburgh Postnatal Depression Scale was used to evaluate postpartum depressive symptoms after birth, with a score of >9 defining PPD. Data were collected using specially designed questionnaires or data from the electronic database of Tianjin Maternal and Child Health Information System. Odds ratios (OR) and 95 percent confidence intervals (CI) were obtained for the association of smoking status with PPD using binary logistic regression. Passive smoke exposure rates before and during pregnancy were 40.9 percent and 52.1 percent, respectively. A total of 8.5% (n = 747) of participants had PPD. Compared with those not exposed, women passively exposed to smoke before and during pregnancy had higher odds of PPD (before pregnancy: OR: 1.24, 95 percent CI: 1.03-1.50; during pregnancy: OR: 1.43, 95 percent CI: 1.16-1.77) after adjustment for confounding factors. Passive smoking before and during pregnancy were associated with PPD in Chinese women. Reducing passive smoke exposure may reduce PPD in Chinese women; further longitudinal studies are warranted to replicate these findings.

The burden of personality disorders on the DSM 5 addiction to tobacco during pregnancy

BACKGROUND

Tobacco smoking is a major health concern. Many women smoke during their reproductive years, some of them during their pregnancy. Adverse outcomes for the newborns physical health are well recognized, while the influence on their mental health is still under investigation. We aim at demonstrating the contribution of maternal personality disorders in maintaining addiction to tobacco during pregnancy, to underline their role and the need of their detection as a preventive effort.

METHOD

150 women, consecutively admitted to the Perinatal Psychiatric Outpatient Department were tested with the SCID II, CTQ, WHOQOL-BREF, EPDS, BDI and BAI. Tobacco use disorder was attested with the fulfillment of DSM 5 criteria.

RESULTS

46% (n = 69) of the sample was affected by at least one personality disorder ("PD⁺"). "PD⁺" showed a significant higher rate of pregnant women addicted to tobacco (p = 0.021). The average number of cigarettes per day was notably distinct, since patients affected by "NPD" smokes twice the amount compared to "PD^-" and "other PDs", while those affected by Borderline PD has a halfway consumption (7.20 ± 5.54 vs 3.37 ± 4.62 vs 3 ± 3.39 vs 5.50 ± 4.10). ANOVA and POST HOC showed a significance between "NPD" and "other PDs" (p = 0.035), and "other PDs" has significantly the highest rate of active smokers.

CONCLUSION

Personality disorders demonstrate to be a clear contributor in supporting addiction to tobacco during pregnancy. Short and long term health and mental consequences attested in the newborn, encourage awareness in detecting tobacco dependency during this sensitive period. The inclusion of personality evaluation and management in tobacco dependency treatment programs is strictly encouraged to boost their efficiency and increase tobacco abstinence.

Pulmonary Effects of Maternal Smoking on the Fetus and Child: Effects on Lung Development, Respiratory Morbidities, and Life Long Lung Health

Maternal smoking during pregnancy is the largest preventable cause of abnormal in-utero lung development. Despite well known risks, rates of smoking during pregnancy have only slightly decreased over the last ten years, with rates varying from 5-40% worldwide resulting in tens of millions of fetal exposures. Despite multiple approaches to smoking cessation about 50% of smokers will continue to smoke during pregnancy. Maternal genotype plays an important role in the likelihood of continued smoking during pregnancy and the degree to which maternal smoking will affect the fetus. The primary effects of maternal smoking on offspring lung function and health are decreases in forced expiratory flows, decreased passive respiratory compliance, increased hospitalization for respiratory infections, and an increased prevalence of childhood wheeze and asthma. Nicotine appears to be the responsible component of tobacco smoke that affects lung development, and some of the effects of maternal smoking on lung development can be prevented by supplemental vitamin C. Because nicotine is the key agent for affecting lung development, e-cigarette usage during pregnancy is likely to be as dangerous to fetal lung development as is maternal smoking.

Smoking, alcohol, and substance use and rates of quitting during pregnancy: is it hard to quit?

Background

Alcohol and substance use is a major health challenge in Turkey, as it is worldwide. Recently, there has been a rapid increase in the number of females using substances and although usage tends to reduce during pregnancy, it is of critical importance to determine its exact level as substance use negatively impacts on the health of both the mother and infant.

Aim

The aim of the present study was to investigate the frequency of smoking, alcohol, and substance use, and quitting rates during pregnancy.

Method

This study was conducted on pregnant females in Sakarya, Turkey. A total of 1,082 consecutively presenting females who agreed to participate in the study were evaluated. The study team prepared a sociodemographic data form and adapted the “Introduction” section, derived from the Addiction Profile Index, to cover substance use during pregnancy.

Results

The substances most frequently used by pregnant females in their previous pregnancies and current pregnancies were cigarettes/tobacco products (11% and 11.8%, respectively), alcohol (0.6% and 0.4%, respectively), and rarely, synthetic cannabinoids (0.3% and 0.2%, respectively). Daily tobacco smokers continued to smoke during pregnancy, with a rate of 42.5%. Based on research into predictors of smoking (cigarettes) in pregnancy, a correlation was found between lifetime smoking and smoking during a previous pregnancy. A similar link was found with respect to alcohol.

Conclusion

Cigarettes are the most frequently used substance in pregnancy, and to a lesser extent, alcohol and synthetic cannabinoids, also considered to be risky substances. A high incidence of smoking regularly during pregnancy was found in daily smokers. It is recommended that physicians should sensitively ask pregnant females presenting at clinics about all forms of substance use, including alcohol and synthetic cannabinoids, and to include such questions in their routine enquiries.
