Stressful events and continued smoking and continued alcohol consumption during mid-pregnancy

An Evaluation of Food and Nutrient Intake among Pregnant Women in The Netherlands: A Systematic Review

Nutritional deficiencies during pregnancy can have serious consequences for the health of the (unborn) child. This systematic review provides an updated overview of the available food and nutrient intake data for pregnant women in The Netherlands and an evaluation based on the current recommendations. Embase, MEDLINE, and national institute databases were used. Articles were selected if they had been published since 2008 and contained data on food consumption, nutrient intake, or the status of healthy pregnant women. A qualitative comparison was made with the 2021 Dutch Health Council recommendations and reference values. A total of 218 reports were included, representing 54 individual studies. Dietary assessments were primarily performed via food frequency questionnaires. Protein, vitamin A, thiamin, riboflavin, vitamin B₆, folate, vitamin B₁₂, vitamin C, iron, calcium, and magnesium intakes seemed to be adequate. For folate and vitamin D, supplements were needed to reach the recommended intake. The reasons for concern are the low intakes of fruits, vegetables, and (fatty) fish, and the intakes of alcohol, sugary drinks, and salt. For several foods and nutrients, no or limited intake data were found. High-quality, representative, and recent data are needed to evaluate the nutrient intake of pregnant women in order to make accurate assessments and evaluations, supporting scientific-based advice and national nutritional policies.

Alcohol consumption after pregnancy awareness and the additive effect of pregnancy-related anxiety and child abuse

This study examined whether pregnant women alter their alcohol consumption upon pregnancy awareness and any additive effect of a maternal history of child abuse and pregnancy-related anxiety in predicting antenatal alcohol consumption. Pregnant women (N = 548, M = 31.44, SD = 4.58) completed an online survey consisting of the Pregnancy-related Anxiety Scale, Adverse Childhood Experience Questionnaire, questions on alcohol consumption and demographics. The Wilcoxon test examined difference scores between pre-pregnancy awareness and post-awareness drinking. More women reduced or ceased drinking after pregnancy awareness (M = 0.15, SD = 1.03) than before pregnancy recognition (M = 3.12, SD = 3.91). Only two women increased their alcohol consumption, with 140 reporting no change. In the hierarchical regression analysis, child abuse was not significant in the model, whereas pregnancy-related anxiety predicted alcohol consumption, with pre-pregnancy drinking the strongest predictor. There was no significant interaction effect between pregnancy-related anxiety and child abuse. While limited by a cross-sectional design and single questions to assess alcohol intake, our findings are consistent with extant literature. Findings related to child abuse were not significant, and likely due to low prevalence in the sample, Despite this, we further established that pregnancy-related anxiety remains a significant predictor of antenatal drinking regardless of how much alcohol a woman may consume pre-pregnancy. This relationship may be explained by drinking used to cope with pregnancy-related anxieties. While current guidelines recommend alcohol screening, many women may not accurately report their alcohol intake screening for pregnancy-related anxiety may provide an avenue to identify women more at risk of drinking during pregnancy.

Tobacco consumption from the 1st trimester of pregnancy to 7 months postpartum: Effects of previous tobacco consumption, and depression and anxiety symptoms

OBJECTIVE

Previous tobacco consumption, and depression and anxiety symptoms are major predictors of women's tobacco consumption during pregnancy and the postpartum period. However, the joint effect of these predictors is still unexplored. This study aimed to analyse the effects of previous tobacco consumption, and depression and anxiety symptoms on women's tobacco consumption status and quantity from the 1st trimester of pregnancy to 7 months postpartum.

METHOD

A sample of 803 Spanish women was assessed at the 1st and the 3rd trimester of pregnancy, and at 2 and 7 months postpartum. Previous tobacco consumption, and depression and anxiety symptoms were self-reported. Pregnancy and postpartum tobacco consumption were confirmed with biochemical tests.

RESULTS

Women with more previous tobacco consumption or more anxiety symptoms presented a steeper decrease in the number of cigarettes smoked per week from the 1st trimester of pregnancy to the childbirth, although smoking more cigarettes than women with less previous tobacco consumption or less anxiety symptoms. Women with more depression symptoms showed a higher tendency to relapse smoking during the first 2 months postpartum.

CONCLUSIONS

Previous tobacco consumption and anxiety symptoms were associated with higher smoking quantity during pregnancy, while depression symptoms were associated with consumption relapse during postpartum period.

Continued tobacco consumption during pregnancy and women's depression and anxiety symptoms

OBJECTIVES

This study aimed to analyse depression and anxiety symptoms changes from the first to the third trimester of pregnancy in non-smokers versus quitters versus continuous smokers, and the contribution of depression and anxiety symptoms to continued tobacco consumption during pregnancy.

METHODS

The sample comprises 850 Spanish pregnant women (595 non-smokers, 123 quitters, and 132 continuous smokers), assessed at the first and the third trimester of pregnancy with a questionnaire concerning socio-demographic, obstetric, and tobacco consumption information, and measures of depression and anxiety.

RESULTS

Continuous smokers during pregnancy showed more depression and anxiety symptoms than both non-smokers and quitters and no changes from the first trimester to the third trimester of pregnancy, while both non-smokers and quitters revealed a decrease in depression and anxiety symptoms. More anxiety symptoms at the first trimester (OR 1.03) and depression symptoms at the third trimester (OR 1.14) were associated with continued smoking during pregnancy.

CONCLUSIONS

Anxiety and depression symptoms need to be considered to screening for women at risk of smoking during pregnancy. Future prenatal smoking cessation interventions must take into account these variables.

Food Consumption, Nutrient Intake and Status during the First 1000 days of Life in the Netherlands: a Systematic Review

Adequate nutrition is essential for growth and development in early life. Nutritional data serves as a basis for national nutritional guidelines and policies. Currently, there is no insight into the availability of such data during the first 1000 days of life. Therefore, a systematic review was performed, following the PRISMA reporting guideline, to identify studies on food consumption, nutrient intake or status in the Netherlands. Potential gaps were identified, and the quality of the studies is discussed. The databases Embase and Medline were used, as well as databases from national institutes. Articles published in 2008-2018 were screened by two independent reviewers. In total 601 articles were identified, of which 173 were included. For pregnant women, 32 studies were available with nutritional data, for young children 40 studies were identified. No studies were available for breastfeeding women. A large variety of foods and nutrients were assessed, however certain nutrients were lacking (e.g., vitamin K). Overall, the studies had methodological limitations, making the data unsuitable to assess nutrient inadequacies. There is a need for recent, high quality nutritional research to strengthen the understanding of the nutritional needs and deficiencies during early life, and is fundamental for national guidelines and policies.

Stressful life events and alcohol consumption in pregnant women: A cross-sectional survey

BACKGROUND

Psychological stress in pregnancy has been related to different adaptations (physical, emotional and social) of the woman's life during this period. Although maternal stress is a common occurrence in pregnancy, studies indicate that the high levels of stressful life events are a predisposing factor to alcohol consumption in pregnant women. Though postnatal maternal emotional distress has been extensively investigated, little is known about the association between stressful life events and maternal risk behaviors during pregnancy.

OBJECTIVES

The purpose of this study is to verify the association between stressful life events and alcohol consumption in pregnant women.

DESIGN AND PARTICIPANTS

This is a cross-sectional survey using a convenience sample of 449 women in the third trimester of pregnancy. The participants were recruited in a public maternity hospital in the city located in the state of Sao Paulo, Brazil.

METHODS

A semi-structured interview was used to assess alcohol use and stressful life events of the respondent's life. The semi-structured interview included the following instruments: a socio-demographic questionnaire, inventory for the evaluation of the stressful life events (Interview for Recent life events -IRLE), the questionnaire Tolerance, Annoyed, Cut-down, Eye-Opener (T-ACE) for the use of alcohol, the International Classification of Diseases (ICD-10) criteria for alcohol-related disorders, and the evaluation of consumption before and during each gestational trimester.

RESULTS

Pregnant women diagnosed with alcohol abuse and alcohol dependence according to ICD-10 and with risk consumption, according to T-ACE screening, had a higher occurrence of stressful life events than the group without this diagnosis (p < 0.001). The following stressful life events were more frequent among women with alcohol problems: "Major financial difficulties," "Loss or theft of objects", "Serious argument with non-resident/close family member", "Serious argument with family members," and "Marital separation" with the latter about eight times more common in this group.

CONCLUSION

The results suggest an association between stressful life events and dependence or risk consumption of alcohol in pregnant women. The evaluation of stressful life events by the nursing team can help pregnant women to identify or strengthen healthy coping styles in the face of stress, thus intervene, and avoid alcohol consumption during pregnancy.

Alkoholkonsum während der Schwangerschaft

Zusammenfassung. Kinder sind bereits im Mutterleib sensitiv für Umwelteinflüsse. Pränataler Alkoholkonsum zählt dabei zu den einflussreichsten Risikofaktoren für die frühkindliche Entwicklung. Das Ziel ist es, einen Überblick über die aktuelle Forschungslage zum Thema Alkoholkonsum während der Schwangerschaft zu geben. Darüber hinaus wird der Forschungsstand zu Belastungen und Folgeschäden für die frühkindliche Entwicklung durch pränatale Alkoholexposition, aber auch zu weiteren Risikofaktoren zusammengefasst. Es wird gezeigt, dass das Wissen um die Prävalenz für Alkoholkonsum während der Schwangerschaft sowohl für die Erforschung der Folgen als auch für das Umsetzen von präventiven Maßnahmen ausschlaggebend ist. Die Prävalenzen unterscheiden sich nicht nur regional, sondern können auch durch andere Faktoren beeinflusst werden. Es wird deutlich, dass der Risikofaktor Alkohol und dessen mögliche Auswirkungen auf die frühkindliche Entwicklung nicht isoliert, sondern in Abhängigkeit von weiteren genetischen und Umweltfaktoren betrachtet werden müssen. Denn auch Folgen von weiteren perinatalen Risikofaktoren machen sich in den ersten beiden Lebensjahren bemerkbar. Beispiele für Entwicklungsstörungen in dieser Entwicklungsspanne sind externalisierendes Verhalten und kognitive Beeinträchtigungen. Inwieweit sich perinatale Risikofaktoren jedoch auf Entwicklungsverläufe von Kindern, die durch pränatalen Alkoholkonsum belastet sind, auswirken, erfasst eine umfassende Diskussion. Diese Lücke gilt es zu schließen um das Zusammenspiel perinataler Risiken genauer zu verstehen und adäquat entgegenwirken zu können.

Review of the Relationships Among Psychosocial Stress, Secondhand Smoke, and Perinatal Smoking

OBJECTIVE

To summarize and evaluate the recently published literature in which the relationships among psychosocial stress, smoking, and exposure to secondhand smoke during the perinatal period are examined, and to describe the characteristics and demographics of the samples.

DATA SOURCES

Electronic databases MEDLINE, Academic Search Complete, CINAHL, Psychology and Behavioral Sciences Collection, and PsychINFO. In addition, hand searches of reference lists supplemented the electronic search.

STUDY SELECTION

English language, peer-reviewed studies published between 2010 and 2015 on the relationships of self-reported or perceived stress, smoking, and secondhand smoke exposure during pregnancy and postpartum were included. Twenty-four studies met the inclusion criteria.

DATA EXTRACTION

Data that specified the relationships among smoking, stress, and secondhand smoke exposure during pregnancy and postpartum were extracted from the studies. A table matrix, available as supplemental material, to summarize the literature and sample characteristics and demographics was created.

DATA SYNTHESIS

Evidence from the included studies supported an association between psychosocial stress specific to pregnancy or from other sources and smoking or smoking relapse during pregnancy or in the postpartum period. In the studies in which it was included, exposure to secondhand smoke was cited as a barrier to abstinence.

CONCLUSION

It is probable that women who persistently smoke in pregnancy experience elevated stress. Further research with longitudinal designs and inclusion of secondhand smoke as a variable are needed.

Consequences and Possible Predictors of Health-damaging Behaviors and Mental Health Problems in Pregnancy - A Review

In recent decades, the understanding of the short and longer term effects of health-damaging behaviors and mental health problems in pregnant women and the underlying mechanisms of these behaviors and illnesses has significantly increased. In contrast, little is known about the factors affecting individual pregnant women which contribute to health-damaging behaviors and mental illness. The aim of this paper was therefore to summarize the current state of research into the consequences of nicotine and alcohol consumption, malnutrition, excessive weight gain or obesity, and impaired mental health (depression and anxiety) during pregnancy. In addition, the characteristics of pregnant women which increase their risk of developing such behaviors or mental disorders are described. A better knowledge of these risks should make it easier for clinicians to identify cases at risk early on and put measures of support in place. A review of the literature has shown that certain characteristics of pregnant women (e.g. her relationship with her partner, a previous history of mental illness prior to pregnancy) are associated with various health-damaging behaviors as well as with impaired mental health. Affected women often show an accumulated psychosocial stress which was already present prior to the pregnancy and which may persist even after the birth of the child.

Effects of tobacco exposure on perinatal suicidal ideation, depression, and anxiety

Background

Previous studies have stressed the importance of tobacco exposure for the mood disorders of depression and anxiety. Although a few studies have focused on perinatal women, none have specifically considered the effects of smoking and secondhand smoke exposure on perinatal suicidal ideation. Thus, this study aimed to investigate the relationships of smoking/secondhand smoke exposure status with suicidal ideation, depression, and anxiety from the first trimester to the first month post partum.

Methods

This cross-sectional study based on self-reported data was conducted at five hospitals in Taipei, Taiwan from July 2011 to June 2014. The questionnaire inquired about women’s pregnancy history, sociodemographic information, and pre-pregnancy smoking and secondhand smoke exposure status, and assessed their suicidal ideation, depression, and anxiety symptoms. Logistic regression models were used for analysis.

Results

In the 3867 women in the study, secondhand smoke exposure was positively associated with perinatal depression and suicidal ideation. Compared with women without perinatal secondhand smoke exposure, women exposed to secondhand smoke independently exhibited higher risks for suicidal ideation during the second trimester (odds ratio (OR) = 7.63; 95 % confidence interval (CI) = 3.25–17.93) and third trimester (OR = 4.03; 95 % CI = 1.76–9.23). Women exposed to secondhand smoke had an increased risk of depression, especially those aged 26–35 years (OR = 1.71; 95 % CI = 1.27–2.29).

Conclusions

Secondhand smoke exposure also considerably contributes to adverse mental health for women in perinatal periods, especially for the severe outcome of suicidal ideation. Our results strongly support the importance of propagating smoke-free environments to protect the health of perinatal women.

Tobacco and alcohol use in pregnancy in France: the role of migrant status: the nationally representative ELFE study

INTRODUCTION

Tobacco and alcohol use in pregnancy are modifiable yet frequent risk factors of poor perinatal outcomes. We examined whether characteristics associated with substance use in pregnancy vary between native and migrant women, who often differ in terms of socio-demographic characteristics.

METHODS

Data come from a nationally representative sample of children born in France in 2011 (ELFE study, n=18,014). Maternal substance use in pregnancy (tobacco: ≥1 cigarette/day, alcohol: ≥1 time, binge drinking: ≥3 units of alcohol on one occasion) was assessed using survey methodology by a) trained interviewers and b) self-reports. Migration status was determined based on country of birth (native-born vs. migrant). The sample included 2330 migrant women, predominantly from North Africa (35.4% - primarily Algeria and Morocco), Sub-Saharan Africa (27.3% - primarily Senegal, Ivory Coast, the Congo and Cameroun), Europe (20.2% - primarily Portugal and Germany) and Asia (10.2% - primarily Turkey). Characteristics potentially associated with substance use included socio-demographics (maternal age, number of children, relationship status, educational attainment, employment status), health (psychological difficulties, incomplete prenatal care) and partner's characteristics (migration status, employment).

RESULTS

Compared to the native-born, migrant women had lower levels of tobacco smoking (8.8 vs. 21.9%) and alcohol use (23.4 vs. 40.7%), but not binge drinking (2.9 vs. 3.3%). Unfavorable socioeconomic circumstances were associated with tobacco smoking in native-born women only. Single parenthood was associated with alcohol use only in migrant women. In migrant women, co-occurring use of another substance and psychological difficulties were more strongly associated with use of tobacco, alcohol or binge drinking than in native-born women.

CONCLUSIONS

Migrant women have less favorable socioeconomic characteristics than native women but are generally less likely to use tobacco and alcohol in pregnancy. However those who experience single-parenthood need special attention, as they are disproportionately likely to use psychoactive substances which put them and their children at risk of poor health outcomes.

Alcohol use before and during unwanted pregnancy

BACKGROUND

There is little information about pregnancy-related changes in alcohol use and factors contributing to changes among women with unwanted pregnancies. This study describes changes in alcohol use from before pregnancy recognition to during pregnancy and identifies important predictors of alcohol use severity among women with unwanted pregnancies.

METHODS

Data are from the Turnaway Study of 956 women seeking pregnancy termination at 30 U.S. facilities between 2008 and 2010, some of whom were denied care because they were past the gestational limit of the facility where they were recruited and were still pregnant at the baseline interview, 1 week after termination seeking. Predictors of alcohol use severity (a latent variable) were identified.

RESULTS

About 56% of the total sample reported any alcohol use the month before pregnancy recognition, with 23% reporting 6 or more drinks on an occasion. Among the total sample, 35% of those drinking before pregnancy recognition had quit and 20% had reduced 1 week after termination seeking. Among those denied terminations and still pregnant, 71% had quit and 14% had reduced. In a multivariate model predicting alcohol severity, younger age, still pregnant, 1 or more previous births, later gestation, childhood physical abuse, and marijuana and other drug use were associated with lower severity; having completed college, tobacco use, and recent physical violence were associated with higher severity.

CONCLUSIONS

The proportion of the total sample drinking before pregnancy recognition is similar to national samples of women of childbearing age, while the proportion binge drinking appears higher. Of women denied terminations, who were still pregnant, the proportion having quit is similar to other populations of pregnant women. More research is needed to examine whether pregnant women may be substituting alcohol for marijuana and other drugs. Interventions focusing on alcohol use severity during pregnancy may need to also focus on tobacco.
