Prevalence and correlates of drinking in early pregnancy among women who stopped drinking on pregnancy recognition

Foetal alcohol spectrum disorder in Aotearoa, New Zealand: Estimates of prevalence and indications of inequity

INTRODUCTION

Foetal alcohol spectrum disorder (FASD) is 100% caused by alcohol. The lifelong disability caused by prenatal alcohol exposure cannot be reversed. Lack of reliable national prevalence estimates of FASD is common internationally and true of Aotearoa, New Zealand. This study modelled the national prevalence of FASD and differences by ethnicity.

METHODS

FASD prevalence was estimated from self-reported data on any alcohol use during pregnancy for 2012/2013 and 2018/2019, combined with risk estimates for FASD from a meta-analysis of case-ascertainment or clinic-based studies in seven other countries. A sensitivity analysis using four more recent active case ascertainment studies was performed to account for the possibility of underestimation.

RESULTS

We estimated FASD prevalence in the general population to be 1.7% (95% confidence interval [CI] 1.0%; 2.7%) in the 2012/2013 year. For Māori, the prevalence was significantly higher than for Pasifika and Asian populations. In the 2018/2019 year, FASD prevalence was 1.3% (95% CI 0.9%; 1.9%). For Māori, the prevalence was significantly higher than for Pasifika and Asian populations. The sensitivity analysis estimated the prevalence of FASD in the 2018/2019 year to range between 1.1% and 3.9% and for Māori, from 1.7% to 6.3%.

DISCUSSION AND CONCLUSIONS

This study used methodology from comparative risk assessments, using the best available national data. These findings are probably underestimates but indicate a disproportionate experience of FASD by Māori compared with some ethnicities. The findings support the need for policy and prevention initiatives to support alcohol-free pregnancies to reduce lifelong disability caused by prenatal alcohol exposure.

Quantitation of phosphatidylethanols in dried blood spots to determine rates of prenatal alcohol exposure in Ontario

BACKGROUND

Estimating rates of prenatal alcohol exposure (PAE) in a population is necessary to ensure that proper medical and social supports and interventions are in place. This study sought to estimate PAE in Ontario, Canada by quantifying phosphatidylethanol (PEth) homologues in over 2000 residual neonatal dried blood spots (DBS).

METHODS

A random selection of 2011 residual DBS collected over a 1-week time period were anonymized and extracted. A targeted liquid chromatography-mass spectrometry method was used to quantify 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanol (PEth (16:0/18:1) or POPEth), the clinically accepted biomarker, and six additional PEth homologues. A POPEth level above the United States Drug Testing Laboratories (USDTL) cutoff up to 4 weeks predelivery was indicative of PAE. All PEth homologues were correlated to one another and logistic regression was used to determine the association between PAE status and infant characteristics.

RESULTS

The estimated rate of PAE in Ontario, up to the last 4 weeks of gestation, was 15.5% (POPEth >28.5 nM). Most PEth homologues were moderately to strongly correlated to one another. A low birth weight and preterm birth were both associated with PAE, while being small for gestational age had lower odds of PAE.

CONCLUSIONS

The results of this study suggest that PAE may be more prevalent in Ontario than previous estimates by self-report or meconium testing. These findings support the need to consider the effectiveness of current interventions and the design of new interventions to address this significant public health issue.

Maternal alcohol intakes before and during pregnancy: Impact on the mother and infant outcome to 18 months

Aim:

To investigate maternal alcohol intakes before and during pregnancy, their impact on mothers and infants to 18 months.

Method:

Prospective study of 504 New Zealand volunteers visited in months 4 and 7 of pregnancy, measurements taken, lifestyle details recorded including alcohol intake before and during pregnancy. Eighteen months after birth, 370 infants were measured, and infant development recorded.

Results:

Nineteen per cent of mothers never drank, 53% stopped when they knew they were pregnant, 29% continued to drink. Twenty-two per cent of drinkers binge drank (over 50 g alcohol per session) before pregnancy and 10% during pregnancy. Daily drinking was associated with increased obesity in mothers. Alcohol consumption before or during pregnancy was not associated with infant motor development, had a slight negative effect on growth, and a significant association with vocal ability to 18 months. Energy intake appeared to partially moderate this effect.

Conclusion:

Maternal alcohol consumption exceeding 50 g per session both before and during pregnancy was associated with decreasing vocal ability in the 18-month old infant.

A renewed media-mix, based on the dynamic transactional model, for communicating the harms of alcohol to women in New Zealand

Public health messages are traditionally disseminated using mass media that typically are unidirectional or one-way communication. Consequent to the current media proliferation, two-way communication channels are also available for publishing health messages. Though they differ in operation, they co-exist which is explained by the media complementarity theory. This study reports research that identified the sources that women of childbearing age in New Zealand prefer when seeking information concerning alcohol and pregnancy. Service-dominant logic provided a framework for simultaneously examining the media that were fundamentally different. The information sources were formulated into a media-mix based on the theory of dynamic transactional model (DTM). DTM accounted for media complementarity, combining the one-way and two-way communication channels into a unified communication process and is recommended for use in health promotion.

Associated Factors of Drinking Prior to Recognising Pregnancy and Risky Drinking among New Zealand Women Aged 18 to 35 Years

Nearly half of all pregnant women in the Western world drink prior to recognising pregnancy. The current study aimed to investigate the factors associated with drinking prior to recognising pregnancy among pregnant women and factors associated with risky drinking among nonpregnant sexually active women. The study was a cross-sectional survey of a random sample of women aged 18 to 35 years (n = 1062) selected from the New Zealand electoral roll. Pregnant women (currently pregnant: n = 65; previously pregnant: n = 202) who were risky drinkers and who smoked in the year prior to pregnancy had five times the odds (p < 0.01) and women who planned their pregnancy (p = 0.05) and who used a community service card (p = 0.004) had less than half the odds to drink prior to recognising pregnancy than their respective counterparts. Among sexually active nonpregnant women who consumed alcohol, those who smoked in the year prior to the survey and those who drank for social reasons, for mood enhancement or coping reasons had higher odds of being risky drinkers (p < 0.05). Addressing risky drinking, especially in social settings, and smoking among women of peak childbearing age may mitigate the potential risk of drinking prior to recognising pregnancy.

Fetal Alcohol Spectrum Disorders: A Review of the Neurobehavioral Deficits Associated With Prenatal Alcohol Exposure

In utero alcohol exposure can disrupt the development of the fetal brain and result in a wide range of neurobehavioral outcomes collectively known as fetal alcohol spectrum disorders (FASD). This paper provides a comprehensive review of the cognitive and behavioral outcomes of prenatal alcohol exposure, including domains of general intelligence, executive functioning, language development, learning and memory, adaptive functioning, academic performance, and concurrent psychopathology. In addition, the current status of the neurobehavioral profile of FASD and its potential as a diagnostic tool will be discussed.

Prevalence of alcohol use in pregnant women with substance use disorder

BACKGROUND

Prenatal care programs for women with opioid use disorder (OUD) often focus treatment/counseling plans around illicit substances, while concurrent use of alcohol might present an equal or greater risk to the fetus.

METHODS

This study evaluated self-reported prevalence of alcohol use in patients participating in a comprehensive prenatal care program for women with substance use disorder (SUD; n = 295), of which 95% are treated for OUD, and pregnant women being served through general obstetrical clinics at the University of New Mexico (n = 365). During the screening phase of a prospective study, patients were asked to report alcohol use in the periconceptional period, and between the last menstrual period and pregnancy recognition.

RESULTS

The screening interview was conducted at 22.3 (median = 22; Q1 = 16; Q3 = 29) gestational weeks. Among patients screened at the SUD clinic, 28.8% and 24.1% reported at least one binge drinking episode in the periconceptional period and in early pregnancy, respectively. The prevalence of binge drinking was similar in the general obstetrics population (24.7% and 24.4%, respectively). Among those who reported drinking in early pregnancy, median number of binge drinking episodes was higher among patients screened at the SUD clinic (median = 3; Q1 = 1; Q3 = 10) compared to the general obstetrics group (median = 1; Q1 = 1; Q3 = 3; p < 0.001).

CONCLUSIONS

This study demonstrates a high prevalence of prenatal alcohol use in early pregnancy in both groups, while patients with SUD/OUD consume more alcohol. These findings underscore the need for targeted screening and intervention for alcohol use in all pregnant women, especially those with SUD/OUD.

The Use of Facebook Advertising for Communicating Public Health Messages: A Campaign Against Drinking During Pregnancy in New Zealand

BACKGROUND

Social media is gaining recognition as a platform for delivering public health messages. One area attracting attention from public health researchers and professionals is Facebook's advertising channel. This channel is reported to have a broad reach and generate high user engagement with the disseminated campaign materials. However, to date, no study has examined the communication process via this channel which this study aimed to address.

OBJECTIVE

The specific objectives of the study were to (1) examine user engagement for a public health campaign based on the metadata provided by Facebook, (2) analyze comments generated by the campaign materials using text mining, and (3) investigate the relationship between the themes identified in the comments and the message and the sentiments prevalent in the themes that exhibited significant relationships.

METHODS

This study examined a New Zealand public health pilot campaign called "Don't Know? Don't Drink," which warned against drinking alcohol during pregnancy. The campaign conveyed the warning through a video and three banner ads that were delivered as news feeds to women aged 18-30 years. Thematic analysis using text mining performed on the comments (n=819) identified four themes. Logistic regression was used to identify meaning-making themes that exhibited association with the message.

RESULTS

The users' engagement was impressive with the video receiving 203,754 views. The combined likes and shares for the promotional materials (video and banner ads) amounted to 6125 and 300, respectively. The logistic regression analysis showed two meaning-making themes, namely, risk of pregnancy (P=.003) and alcohol and culture (P<.001) exhibited association with the message. The sentiment analysis carried out on the two themes revealed there were more negative than positive comments (47% vs 28%).

CONCLUSIONS

The user engagement observed in this study was consistent with previous research. The numbers reported for views, likes, and shares may be seen as unique interactions over the fixed period of the campaign; however, survey research would be required to find out the true evaluative worth of these metadata. A close examination of the comments, employing text mining, revealed that the message was not accepted by a majority of the target segment. Self-identity and conformity theories may help to explain these observed reactions, albeit warrant further investigations. Although the comments were predominantly negative, they provide opportunities to engage back with the women. The one-way communication format followed in this campaign did not support any two-way engagement. Further investigation is warranted to establish whether using a two-way communication format would have improved the acceptability of such public health messages delivered via social media. The findings of this study caution using a one-way communication format to convey public health messages via Facebook's advertising channel.

Peri-Conceptual and Mid-Pregnancy Alcohol Consumption: A Comparison between Areas of High and Low Deprivation in Scotland

BACKGROUND

Alcohol-related mortality and morbidity among women has increased over recent decades, especially in areas of higher deprivation. Pre-pregnancy alcohol use is associated with continued consumption in pregnancy. We assessed whether general population alcohol consumption patterns were reflected among pregnant women in two Scottish areas with different deprivation levels.

METHODS

Cross-sectional study in two health boards (HB1, lower deprivation levels, n = 274; HB2, higher deprivation levels, n = 236), using face-to-face 7-day Retrospective Diary estimation of peri-conceptual and mid-pregnancy alcohol consumption.

RESULTS

A greater proportion of women in HB2 (higher deprivation area) sometimes drank peri-conceptually, but women in HB1 (lower deprivation area) were more likely to drink every week (49.6 vs 29.7%; p < 0.001) and to exceed daily limits (6 units) at least once each week (32.1 vs 14.8%; p < 0.001). After pregnancy recognition, consumption levels fell sharply, but women in HB2 were more likely to drink above recommended daily limits (2 units) each week (2.5 vs 0.0%; p < 0.05). However, women in HB1 were more likely to drink frequently. Women with the highest deprivation scores in each area drank on average less than women with the lowest deprivation scores.

CONCLUSIONS

Heavy episodic and frequent consumption was more common in the lower deprivation area, in contrast with general population data. Eliciting a detailed alcohol history at the antenatal booking visit, and not simply establishing whether the woman is currently drinking, is essential. Inconsistent messages about the effects of alcohol in pregnancy may have contributed to the mixed picture we found concerning peri-conceptual and mid-pregnancy alcohol consumption.

Evaluation of a retrospective diary for peri-conceptual and mid-pregnancy drinking in Scotland: a cross-sectional study

INTRODUCTION

Heavy episodic ("binge") drinking among women in Scotland is commonplace; prepregnancy drinking is associated with continued antenatal drinking. Evidence for effectiveness of standardized antenatal alcohol assessment is lacking. Alcohol-exposed pregnancies may be missed. We assessed peri-conceptual and mid-pregnancy consumption using a week-long retrospective diary and standard alcohol questionnaires, and evaluated the agreement between these instruments.

MATERIAL AND METHODS

Cross-sectional study in two Scottish health board areas involving 510 women attending mid-pregnancy ultrasound scan clinics. Face-to-face administration of alcohol retrospective diary and AUDIT or AUDIT-C assessed weekly and daily alcohol consumption levels and patterns. Depression-Anxiety-Stress Scale (DASS-21) assessed maternal wellbeing. A sub-sample (n = 30) provided hair for alcohol metabolite analysis. Pearson's correlation coefficient investigated associations between questionnaires and alcohol metabolite data.

RESULTS

The response rate was 73.8%. The retrospective diary correlated moderately with AUDIT-C and AUDIT but elicited reports of significantly higher peri-conceptual consumption, (median unit consumption on "drinking days" 6.8; range 0.4-63.8). Additional "special occasions" consumption ranged from 1 to 125 units per week. Correlations between DASS-21 and retrospective diary were weak. Biomarker analysis identified three instances of hazardous peri-conceptual drinking.

CONCLUSIONS

Women reported higher consumption levels when completing the retrospective diary, especially regarding peri-conceptual "binge" drinking. Routine clinical practice methods may not capture potentially harmful or irregular drinking patterns. Given the association between prepregnancy and antenatal drinking, and alcohol's known teratogenic effects, particularly in the first trimester, the retrospective diary may be a useful low-tech tool to gather information on alcohol intake patterns and levels.

Implication of alcohol consumption on aggregate wellbeing

AIMS

The effects of drinking alcohol extend beyond the individuals concerned to the wider community. While there is recognition of such a global implication, currently no study has quantified the impact of alcohol consumption on aggregate wellbeing. This study aims to address this gap and attempts to investigate the impact of various levels of alcohol consumption on aggregate happiness.

METHODS

The study was carried out on a random selection of participants ( n = 1,817) drawn from the 3Di consumer panel, comprising over 170,000 New Zealanders aged 18 and above. Using a subjective happiness scale (SHS) in conjunction with the Alcohol Use Disorders Identification Test (AUDIT), investigation was carried out to find whether drinking behaviour affected aggregate happiness.

RESULTS

SHS and AUDIT scores were negatively correlated and the strength of the correlation increased with the intensity of problematic drinking. Regression analysis showed that the beta coefficient was positive for the low-risk (.074) and negative for the high-risk (-.081) category, suggesting approaches to intervene with the growing problem of alcohol consumption in modern societies.

CONCLUSION

Measurements of happiness can explain the global implication of alcohol in wellbeing terms. The findings of this study indicated that low-risk drinkers affected aggregate happiness positively, whereas high-risk drinkers affected aggregate happiness negatively. While the latter observation is not new, the former raises the need to promote moderation in drinking alcohol for the common good of everyone.

Peri-conceptual and mid-pregnancy drinking: a cross-sectional assessment in two Scottish health board areas using a 7-day Retrospective Diary

AIMS

The aim of this study was to evaluate the use of a 7-day Retrospective Diary to assess peri-conceptual and mid-pregnancy alcohol consumption.

BACKGROUND

Alcohol consumption among women has increased significantly and is of international concern. Heavy episodic ('binge') drinking is commonplace and is associated with unintended pregnancy. Pre-pregnancy drinking is strongly associated with continued drinking in pregnancy. Routine antenatal assessment of alcohol history and current drinking is variable; potentially harmful peri-conceptual drinking may be missed if a woman reports low or no drinking during pregnancy.

DESIGN

Cross-sectional study (n = 510) in two Scottish health board areas.

METHODS

Face-to-face Retrospective Diary administration from February to June 2015 assessing alcohol consumption in peri-conceptual and mid-pregnancy periods. Women were recruited at the mid-pregnancy ultrasound clinic.

RESULTS

Of 510 women, 470 (92·0%) drank alcohol before their pregnancy; 187 (39·9%) drank every week. Retrospective assessment of peri-conceptual consumption identified heavy episodic drinking (more than six units on one occasion) in 52·2% (n = 266); 19·6% (n = 100) reported drinking more than 14 units per week, mostly at the weekend; 'mixing' of drinks was associated with significantly higher consumption. While consumption tailed off following pregnancy recognition, 5·5% (n = 28) still exceeded the recommended daily two-unit limit in pregnancy. Multivariable logistic regression identified that women who 'binged' peri-conceptually were 3·2 times more likely to do this.

CONCLUSION

Statistically significant peri-conceptual consumption levels suggest a substantial proportion of alcohol-exposed pregnancies before pregnancy recognition. Not taking a detailed alcohol history, including patterns of consumption, will result in under-detection of alcohol-exposed pregnancies. The Retrospective Diary offers practitioners a detailed way of enquiring about alcohol history for this population.

"Did you ever drink more?" A detailed description of pregnant women's drinking patterns

BACKGROUND

This paper presents drinking patterns in a prospective study of a population-based cohort of 1570 pregnant women using a combination of dose and timing to give best estimates of prenatal alcohol exposure (PAE). Novel assessments include women's special occasion drinking and alcohol use prior to pregnancy recognition.

METHODS

Information on up to nine types of alcoholic drink, with separate frequencies and volumes, including drinking on special occasions outside a 'usual' pattern, was collected for the periconceptional period and at four pregnancy time points. Weekly total and maximum alcohol consumption on any one occasion was calculated and categorised. Drinking patterns are described in the context of predictive maternal characteristics.

RESULTS

41.3 % of women did not drink during pregnancy, 27 % drank in first trimester only; most of whom stopped once they realised they were pregnant (87 %). When compared to women who abstained from alcohol when pregnant, those who drank in the first trimester only were more likely to have an unplanned pregnancy and not feel the effects of alcohol quickly. Almost a third of women continued to drink alcohol at some level throughout pregnancy (27 %), around half of whom never drank more than at low or moderate levels. When compared with abstainers and to women who only drank in trimester one, those who drank throughout pregnancy tended to be in their early to mid-thirties, smoke, have a higher income and educational attainment. Overall, almost one in five women (18.5 %) binge drank prior to pregnancy recognition, a third of whom were identified with a question about 'special occasion' drinking. Women whose age at first intoxication was less than 18 years (the legal drinking age in Australia), were significantly more likely to drink in pregnancy and at binge levels prior to pregnancy recognition.

CONCLUSIONS

We have identified characteristics of pregnant women who either abstain, drink until pregnancy awareness or drink throughout pregnancy. These may assist in targeting strategies to enhance adherence to an abstinence policy and ultimately allow for appropriate follow-up and interpretation of adverse child outcomes. Our methodology also produced important information to reduce misclassification of occasional binge drinking episodes and ensure clearly defined comparison groups.

Updated Clinical Guidelines for Diagnosing Fetal Alcohol Spectrum Disorders

The adverse effects of prenatal alcohol exposure constitute a continuum of disabilities (fetal alcohol spectrum disorders [FASD]). In 1996, the Institute of Medicine established diagnostic categories delineating the spectrum but not specifying clinical criteria by which diagnoses could be assigned. In 2005, the authors published practical guidelines operationalizing the Institute of Medicine categories, allowing for standardization of FASD diagnoses in clinical settings. The purpose of the current report is to present updated diagnostic guidelines based on a thorough review of the literature and the authors' combined expertise based on the evaluation of >10 000 children for potential FASD in clinical settings and in epidemiologic studies in conjunction with National Institute on Alcohol Abuse and Alcoholism-funded studies, the Collaborative Initiative on Fetal Alcohol Spectrum Disorders, and the Collaboration on FASD Prevalence. The guidelines were formulated through conference calls and meetings held at National Institute on Alcohol Abuse and Alcoholism offices in Rockville, MD. Specific areas addressed include the following: precise definition of documented prenatal alcohol exposure; neurobehavioral criteria for diagnosis of fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder; revised diagnostic criteria for alcohol-related birth defects; an updated comprehensive research dysmorphology scoring system; and a new lip/philtrum guide for the white population, incorporating a 45-degree view. The guidelines reflect consensus among a large and experienced cadre of FASD investigators in the fields of dysmorphology, epidemiology, neurology, psychology, developmental/behavioral pediatrics, and educational diagnostics. Their improved clarity and specificity will guide clinicians in accurate diagnosis of infants and children prenatally exposed to alcohol.

Prevalence and pattern of alcohol consumption during pregnancy in the Netherlands

Objective

To estimate the prevalence of alcohol consumption during pregnancy in the Netherlands in 2007 and 2010.

Method

During two identical, nation-wide surveys in 2007 and 2010, questionnaires were handed out to mothers of infants aged ≤6 months who visited a Well-Baby Clinic. By means of the questionnaire mothers were, in addition to questions on infant feeding practices and background variables, asked about their alcohol consumption before, during and after pregnancy. Logistic regression analyses were used to look into relationships of alcohol consumption with maternal and infant characteristics.

Results

We obtained 2,715 questionnaires in 2007, and 1,410 in 2010. Within 6 months before pregnancy, 69 % of women consumed alcohol (data from 2010). During pregnancy 22 % consumed alcohol in 2007, 19 % in 2010. During the first three months of pregnancy, 17 % (2007) and 14 % (2010) of mothers consumed alcohol. Alcohol consumption was mainly one glass (~10 g alcohol) on less than one occasion per month. Compared to 2007, in 2010 more women consumed 1–3 or >3 glasses alcohol per occasion (resp. 11 % to 7 % and 1.4 to 0.7 %). Older women and those with a higher education consumed more alcohol, as did smokers. Birth weight, gestational age and weight for gestational age were not associated with alcohol consumption. In 2007 and 2010, 2.5 % resp. 2.4 % of pregnant women both smoked and consumed alcohol; resp. 70 % and 75 % did neither.

Conclusion

In contrast to Dutch guidelines which advice to completely abstain from alcohol, one in five women in the Netherlands consume alcohol during pregnancy.

Prevalence and characteristics of fetal alcohol spectrum disorders

OBJECTIVES

To determine the prevalence and characteristics of fetal alcohol spectrum disorders (FASD) among first grade students (6- to 7-year-olds) in a representative Midwestern US community.

METHODS

From a consented sample of 70.5% of all first graders enrolled in public and private schools, an oversample of small children (≤ 25th percentile on height, weight, and head circumference) and randomly selected control candidates were examined for physical growth, development, dysmorphology, cognition, and behavior. The children's mothers were interviewed for maternal risk.

RESULTS

Total dysmorphology scores differentiate significantly fetal alcohol syndrome (FAS) and partial FAS (PFAS) from one another and from unexposed controls. Alcohol-related neurodevelopmental disorder (ARND) is not as clearly differentiated from controls. Children who had FASD performed, on average, significantly worse on 7 cognitive and behavioral tests and measures. The most predictive maternal risk variables in this community are late recognition of pregnancy, quantity of alcoholic drinks consumed 3 months before pregnancy, and quantity of drinking reported for the index child's father. From the final multidisciplinary case findings, 3 techniques were used to estimate prevalence. FAS in this community likely ranges from 6 to 9 per 1000 children (midpoint, 7.5), PFAS from 11 to 17 per 1000 children (midpoint, 14), and the total rate of FASD is estimated at 24 to 48 per 1000 children, or 2.4% to 4.8% (midpoint, 3.6%).

CONCLUSIONS

Children who have FASD are more prevalent among first graders in this Midwestern city than predicted by previous, popular estimates.
