Gestational Iron Supplementation Improves Fetal Outcomes in a Rat Model of Prenatal Alcohol Exposure.

Prenatal alcohol exposure causes neurodevelopmental disability and is associated with a functional iron deficiency in the fetus and neonate, even when the mother consumes an apparently iron-adequate diet. Here, we test whether gestational administration of the clinically relevant iron supplement Fer-In-Sol mitigates alcohol’s adverse impacts upon the fetus. Pregnant Long-Evans rats consumed an iron-adequate diet and received 5 g/kg alcohol by gavage for 7 days in late pregnancy. Concurrently, some mothers received 6 mg/kg oral iron. We measured maternal and fetal weights, hematology, tissue iron content, and oxidative damage on gestational day 20.5. Alcohol caused fetal anemia, decreased fetal body and brain weight, increased hepatic iron content, and modestly elevated hepatic malondialdehyde (p’s < 0.05). Supplemental iron normalized this brain weight reduction in alcohol-exposed males (p = 0.154) but not female littermates (p = 0.031). Iron also reversed the alcohol-induced fetal anemia and normalized both red blood cell numbers and hematocrit (p’s < 0.05). Iron had minimal adverse effects on the mother or fetus. These data show that gestational iron supplementation improves select fetal outcomes in prenatal alcohol exposure (PAE) including brain weight and hematology, suggesting that this may be a clinically feasible approach to improve prenatal iron status and fetal outcomes in alcohol-exposed pregnancies.

The impact of micronutrient supplementation in alcohol-exposed pregnancies on reaction time responses of preschoolers in Ukraine.

The potential of micronutrients to ameliorate the impact of prenatal alcohol exposure (PAE) on attentional regulation skills was explored in a randomized clinical trial conducted in Ukraine. Women who differed in prenatal alcohol use were recruited during pregnancy and assigned to one of three groups [No study-provided supplements, Multivitamin/Mineral Supplement (MVM), or MVM plus Choline]. Their offspring were seen in the preschool period and a reaction time task was administered. Participants were asked to press a response button as quickly as possible as 30 stimuli from the same category (animals) were presented consecutively and then followed by six stimuli from a novel category (vehicles). Number correct, mean latency of the response over trials, and variability in the latency were analyzed separately by sex. During the initial animal trials, boys whose mothers received MVM during pregnancy had more correct responses and reduced response latency compared to boys whose mothers had no MVM treatment. During vehicle trials, maternal choline supplementation was associated with increased response speed in males without a PAE history. Females receiving supplements did not show the same benefits from micronutrient supplementation and were more adversely impacted by prenatal alcohol exposure. Relationships between maternal levels of choline, betaine, and dimethylglycine (DMG) and task performance were also assessed. Although no effects were found for choline after adjusting for multiple comparisons, lower baseline DMG level was associated with greater accuracy and shorter latency of responses in the initial animal trials and shorter latency in the vehicle trials in female preschoolers. Level of betaine in Trimester 3 was associated with reduced variability in the latency of male responses during the animal trials. Maternal micronutrient supplementation in pregnancy appears to improve preschool reaction time performance, but the effects varied as a function of sex and PAE exposure status.

Adaptations of an RCT during COVID: Case Study in one Rural American Indian Community.

The COVID-19 pandemic is global in nature but especially threatens American Indian and Alaska Native (AI/AN) communities due to pre-existing conditions and social determinants of health. Because of the higher risk to AI/AN communities, many tribal nations have been proactive in their policies to keep the virus at bay, including travel restrictions and lockdowns. This affected tribal programs as well as collaborative research projects. One project impacted is the Native CHOICES project, an ongoing randomized controlled trial with an AI/AN community that is focused on the prevention of alcohol-exposed pregnancies. Originally designed to be conducted via in-person motivational interviewing sessions, COVID-19 restrictions precluded the intervention from being delivered in-person as it was designed. The study team received valuable input from the project’s Community Advisory Board (CAB) and community-based staff to establish a feasible and acceptable way of conducting the intervention while respecting tribally-enacted COVID-19 restrictions. The goal of this brief report is to outline not just the process to adapting to COVID-19 but also to provide recommendations for future public health programs, including the ongoing need to consider gaps in access affecting resource-poor settings.

Untargeted Metabolome Analysis of Alcohol-Exposed Pregnancies Reveals Metabolite Differences That Are Associated with Infant Birth Outcomes

Untargeted Metabolome Analysis of Alcohol-Exposed Pregnancies Reveals Metabolite Differences That Are Associated with Infant Birth Outcomes

Preconception interventions to reduce the risk of alcohol-exposed pregnancies: A systematic review.

The preconception period provides a unique opportunity to optimize the health of women and children. High rates of alcohol use and unintended pregnancies are common across many Western societies, and alcohol-exposed pregnancies (AEPs) are a possible unintended outcome. The aim of the current study was to evaluate preconception interventions for the prevention of AEPs. A systematic search of four electronic databases (PubMed, Embase, CINAHL, and PsycINFO) was undertaken for relevant peer-reviewed articles published from 1970 onward. Studies were included if they enrolled women and/or their support networks during the preconception period. Nineteen studies met the inclusion criteria. The majority of studies (n=14) evaluated CHOICES-based interventions, which incorporate motivational interviewing approaches to change alcohol and/or contraceptive behavior. The other five interventions included a range of different approaches and modes of delivery. The majority of interventions were successful in reducing AEP risk. Changes in AEP risk were more often driven by changes in contraceptive behavior, although some approaches led to changes in both alcohol and contraceptive behavior. The review indicated that many interventions were efficacious at reducing AEP risk during the preconception period through preventing unplanned pregnancy. The effectiveness estimated from these clinical trials may be greater than that seen in interventions when implemented in practice where there is a lack of blinding and greater attrition of participants during follow-up. Further research investigating the real-world effectiveness of these intervention approaches implemented across a wide range of clinical settings would be beneficial.

Alcohol use during pregnancy in post-conflict northern Uganda: pregnant women\u2019s experiences and provider perceptions

BackgroundAlcohol use during pregnancy has been associated with several birth defects and developmental disabilities generally known as Fetal Alcohol Spectrum Disorders (FASD). Contextual in-depth understanding on why women drink while pregnant is scarce. For this reason, we explored pregnant women’s experiences, knowledge, attitudes as well as provider perceptions regarding prenatal alcohol consumption to inform interventions meant to address alcohol-exposed pregnancies in post-conflict settings.MethodsIn the months of May and June 2019, 30 in-depth interviews were conducted with pregnant mothers who reported maternal alcohol use during pregnancy. In addition 30 Key informant interviews were carried out with health workers providing Antenatal Care services (ANC) in health facilities in Gulu, Kitgum and Pader districts in Northern Uganda. Data was recorded, transcribed and subjected to thematic content analysis.ResultsWomen reported diverse views regarding maternal alcohol use during pregnancy. Whereas some felt it was favourable, others had misgivings about it. There was marked variability in knowledge on dangers of drinking during pregnancy. In this study, women reported that they found themselves in alluring situations that predisposed them to drinking alcohol. These included brewing alcohol as a source of livelihood, pregnancy-induced craving for alcohol, and participation in cultural festivities that are characterised by eating and drinking alcohol. Nonetheless, women who consume alcohol during pregnancy were not held in high esteem in the Acholi communities. Various prevention interventions reportedly existed in communities to address alcohol use during pregnancy including ANC health education, public debates, radio talk shows, community health worker group and individual counselling, and local council by laws.Conclusions and recommendationsPregnant mothers in post-conflict northern Uganda regard alcohol as a remedy to some of the social, economic and health challenges they face. Hence they continue drinking even during pregnancy because of the existing socio-cultural norms that promote it. The findings of this study demonstrate a need for sensitising communities in which pregnant women live so they can provide a supportive environment for mothers to abstain from alcohol consumption during pregnancy. Health care providers should ensure pregnant women consistently receive accurate and honest messages on the dangers of drinking during pregnancy so they can make informed decisions.

Where there's a will, there's a way? Strategies to reduce or abstain from alcohol use developed by Northern Plains American Indian women participating in a brief, alcohol-exposed pregnancy preconceptual intervention.

Alcohol-exposed pregnancy (AEP) is an ongoing concern, especially within low-resource, high-risk areas such as rural American Indian/Alaska Native (AIAN) communities. Brief, preconceptual AEP-reduction interventions are popular in such areas but have a small impact on alcohol use. Developing a strategic alcohol change plan is a key program component; however, there is little research on strategy selection, especially within contexts that positively or negatively impact selection (e.g., cultural strengths, trauma, collective efficacy within AIAN communities). This study qualitatively analyzed strategies chosen to reduce alcohol use by AIAN women participating in a culturally tailored, brief, preconceptual AEP-reduction intervention. One hundred-sixtyNorthern Plains AIAN women who were participating in a brief AEP-reduction program developed a plan to accomplish an alcohol reduction/abstention goal at the first and last program sessions. The plan included choosing 1 or more strategies to (1) achieve the goal, (2) mitigate barriers, and (3) use cultural strengths. Qualitative analysis of the data involved thematic open and structured coding of all 3strategies separately. We also examined how many different themes (different individual strategies) participants reported for each strategy component. Most participants reported only 1 strategy (theme) for each of the 3 components. Common goal-achieving and barrier-mitigation strategies included positive social supports and avoiding negative or alcohol-involved social environments. Other strategies involved circular logic (e.g., the strategy to reduce drinking was to drink less). Both traditional and western cultural strengths were reported as important resources, although many participants had no cultural resource strategy. Programs aimed at reducing AEPs may need to provide participants more support to develop strong strategies to reduce alcohol use when implemented within areas with high levels of trauma and contextual barriers that can impact strategy selection. Such support could include ways to improve health on both interpersonal and community levels.

Alcohol Consumption during COVID among Women with an Existing Alcohol-Use Disorder.

Prior to the pandemic, our research team implemented a randomized controlled trial of an intervention to reduce risk for alcohol-exposed pregnancy (AEP) in American Indian women. When active recruitment for the in-person trial was paused due to COVID, the research team moved to conducting follow-up surveys with participants who had completed the intervention to better understand changes to their alcohol use during the pandemic. We collected surveys from 62 American Indian women who had completed the Native CHOICES intervention. Baseline data collected pre-COVID included demographics and scores on the Alcohol Use Disorders Identification Test (AUDIT). Follow-up surveys conducted during the active pandemic period included a self-reported questionnaire about changes in drinking patterns. At pre-COVID baseline, all participants were engaged in heavy or binge drinking. At follow-up during COVID, 24.2% reported drinking more, and over half had at least one binge drinking episode. Approximately half reported reduced drinking. We found that risky drinking remained an issue during the pandemic for many American Indian women who had engaged in this behavior pre-COVID, while others reported reducing their alcohol consumption. As the pandemic abates, concerted efforts must be made to reach those with identified alcohol use disorders to offer resources and intervention as needed.

Maternal psycho-social risk factors associated with maternal alcohol consumption and Fetal Alcohol Spectrum Disorder: a systematic review.

Fetal Alcohol Spectrum Disorder (FASD) is a preventable range of neurocognitive disorders associated with the biological mother's consumption of alcohol during pregnancy. However, on average, 45% of Australian women continue to consume alcohol during pregnancy resulting in a high rate of alcohol-exposed pregnancies and risk of FASD. This level of exposure is higher than the estimated global average of alcohol-exposed pregnancies (9.8%). This systematic literature review aims to identify demographic, health and psycho-social variables associated with alcohol consumption during pregnancy which may lead to FASD. Using PRISMA principles, this systematic literature review reports on psycho-social factors which increase the risk of alcohol consumption during pregnancy thereby increasing the risk of FASD. Fourteen studies were accepted into this review. Studies were conducted across several countries and included a total of 386,067 cases. Seven studies were case-controlled and seven were cross-sectional design. Multiple studies identified the significance of prior mental illness, anxiety, depression, exposure to abuse and/or domestic violence and alcohol consumption behaviours of partners and family members as strong predictors of risky alcohol consumption during pregnancy and therefore associated risk of FASD. Clinical services may be able to use the evidence-based findings from this review to improve assessment and treatment services for vulnerable women to reduce alcohol-exposed pregnancies.

Reasons and obstacles for changing risky drinking behavior among Latinas at risk of an alcohol-exposed pregnancy

This study examined reasons and obstacles for changing risky alcohol use behavior among Latina adults at risk of an alcohol-exposed pregnancy. Using qualitative methods, data from CHOICES Plus intervention sessions of Latinas (N = 59) were analyzed. Reasons for wanting to change risky alcohol use centered on health, parenting, interpersonal conflict, control, and risk of harm. Obstacles included social obstacles, belief that drinking was not risky, and drinking to manage mood. Differences were found across level of acculturation. Knowledge about salient motives and obstacles is critical to addressing the needs and strengths of Latinas at risk of an alcohol-exposed pregnancy.

Brief intervention aimed at fetal alcohol syndrome prevention: effectiveness study

Aim of the studyThis article represents the results of the study aimed at the research of psychological effects of a dual-focused brief intervention for prevention of fetal alcohol syndrome and alcohol-exposed pregnancy among childbearing age women in Russia.Subject or material and methods280 women took part in the research. The study used the following methods: screening, «Audit», Calendar method, baseline interview, follow-up interviews at 3, 6 and 12 months, the Big Five questionnaire, the method of motivational induction, the method of assessing the level of subjective control.ResultsThe study measured women’s knowledge about FAS and FASD, their attitudes towards alcohol consumption and in particular alcohol use during pregnancy, their real alcohol consumption level, use of contraception, the risk of alcohol-exposed pregnancy and possibly FAS or FASD, the socio-demographical characteristics and psychological features of women.DiscussionThe main factor that influences the formation of attitudes for the refusal of drinking alcohol during pregnancy and the decrease in the level of real alcohol consumption is awareness of the impact of alcohol on the fetus and the health of women, which determines the main content of the prevention program: informing and brief intervention, motivating a change in attitudes and behavior.ConclusionsThe results of the study showed the effectiveness of dual-focused brief intervention and passive informing that were designed and used for FAS prevention.

Reducing the Prevalence of Alcohol-Exposed Pregnancies in the United States: A Simulation Modeling Study.

Public health efforts to prevent alcohol-exposed pregnancies (AEPs) primarily focus on promoting abstinence from alcohol among women if pregnant or seeking pregnancy and using effective contraception to prevent unintended pregnancies if consuming alcohol. Little is known about how programs to improve adherence to these recommendations would affect the prevalence of AEPs. We developed an individual-based simulation model of US women of reproductive age to project the prevalence of AEPs under different public health strategies. The model varies each woman's risk of an AEP over time depending on fertility, contraceptive use, awareness of pregnancy, sexual activity, and drinking patterns. We used the 2013-2015 National Survey on Family Growth data set to parameterize the model. We estimate that 54% (95% uncertainty interval: 48%-59%) of pregnancies that result in a live birth in the United States are exposed to alcohol, 12% (10%-15%) are ever exposed to ≥5 alcoholic drinks in a week, and 3.0% (1.3%-4.2%) to ≥9 drinks. Unintended pregnancies (either due to contraceptive failure or sex without contraceptives) account for 80% (75%-87%) of pregnancies unknowingly exposed to alcohol. We project that public health efforts that focus only on promoting alcohol abstinence among women who are aware of their pregnancy or seeking pregnancy could reduce the prevalence of AEPs by at most 42% (36%-48%). Augmenting this strategy with efforts to avert unintended pregnancies could yield an 80% (73%-86%) reduction in the prevalence of AEPs. Promoting alcohol abstinence among women who are aware of their pregnancy or seeking pregnancy offers limited potential to reduce the prevalence of AEPs. Programs to avert unintended pregnancies are essential to achieve more substantial reductions in AEPs in the United States.

In a Preclinical Model of Prenatal Alcohol Exposure, an Iron Supplementation Intervention Reduces Anxiety-Like Behavior in Both Sexes and Improves Growth in Males

Abstract Objectives Both prenatal iron deficiency and prenatal alcohol exposure (PAE) decrease body weight, increase susceptibility to anxiety, and impair memory and learning in the offspring. PAE itself causes fetal iron deficiency, even when mothers consume sufficient iron. We hypothesized that iron supplementation in PAE pregnancies would not alter offspring growth but would improve measures of anxiety, learning, and memory. Methods Pregnant Long-Evans rats received 5 g/kg/day ethanol or isocaloric maltodextrin (split-dose) from gestational day (GD) 13.5–19.5 and received 6 mg/kg/day iron as ferric sulfate or water from GD12.5–19.5. Male and female offspring were weighed regularly after birth and underwent elevated plus maze (postnatal day (P) 27), open field (P28), novel object recognition (P29–30), T-maze (P32–40), and fear conditioning (P42–50) tests. Mixed model analysis was used to determine significance of the effects of PAE, iron, and sex. Results PAE reduced postnatal body growth in both male (P = 0.028) and female (P = 0.026) offspring. In both sexes, PAE interacted with age to affect growth (P &amp;lt; 0.001) from P5 to P50. In males but not females, iron supplementation interacted with age (P = 0.044) and age and PAE (P = 0.045) to improve growth in PAE + iron males, such that their weights approached control weights by P50. On the elevated plus maze, iron supplementation, regardless of PAE or sex, increased time spent on the open arms by 39–118%, indicating reduced anxiety-like behavior (P = 0.030). On the open field test, time spent in the center was not affected by PAE, iron, or sex (P’s &amp;gt; 0.200). On the novel object recognition test, at delays of both 1 and 24 hours, all groups (except MD + Iron Males with 24-hour delay) recognized the novel object better than chance (P’s &amp;lt; 0.040), but recognition at both time delays was not affected by PAE, iron, or sex (P’s &amp;gt; 0.120), showing that these did not affect recognition memory. On the T-maze and fear conditioning tests, which assess learning and memory, PAE, iron, and sex had no effect on the results (P’s &amp;gt; 0.080). Conclusions This work is the first to investigate gestational iron supplementation as an intervention for alcohol-exposed pregnancies. These results suggest iron supplementation may improve outcomes such as growth in males and anxiety in both sexes in alcohol-exposed populations. Funding Sources NIAAA NIDDK.

A culturally tailored intervention to reduce risk of alcohol-exposed pregnancies in American Indian communities: Rationale, design, and methods

IntroductionPrenatal exposure to alcohol can cause lifelong physical and cognitive challenges in the form of fetal alcohol syndrome and other fetal alcohol spectrum disorders (FASDs). The prevention of prenatal alcohol exposure is thus a public health priority – and one that should account for the particular needs of subpopulations, including in American Indian/Alaska Native (AI/AN) communities. Prior to conception, alcohol-exposed pregnancy prevention is accomplished by encouraging the reduction or elimination of risky alcohol use and/or promoting effective contraceptive use among risky drinkers who could become pregnant. The current study builds on promising findings about the impact of the Centers for Disease Control and Prevention CHOICES intervention with AI/AN communities by implementing a randomized control trial of Native CHOICES, a cultural adaptation of CHOICES, with AI/AN women in a rural reservation community. MethodsAI/AN women aged 18–44 who are at-risk for an alcohol-exposed pregnancy are being recruited. Participants are randomized in 1:1 proportion to the intervention and a services-as-usual, waitlist control condition. The Native CHOICES intervention consists of 2 motivational interviewing (MI) sessions, an elective contraception counseling session, and electronic messaging to boost the effects of MI. Data are collected at baseline and at 6 weeks, 3 months, and 6 months post-baseline. Those assigned to the control group are eligible to enroll in Native CHOICES following the completion of the 6 months post-baseline data collection. In addition to testing intervention effectiveness, the study is designed to yield a comprehensive economic evaluation, which will provide important information regarding the financial feasibility and sustainability of Native CHOICES for healthcare systems serving AI/ANs.

Prevention of Alcohol-Exposed Pregnancies and Fetal Alcohol Spectrum Disorder Among Pregnant and Postpartum Women: A Systematic Review.

Prenatal alcohol exposure can result in a wide range of adverse health outcomes, including in some cases fetal alcohol spectrum disorder (FASD), a lifelong neurodevelopmental disorder. Thus, there is pressing need for effective interventions to prevent alcohol-exposed pregnancies (AEPs). A systematic review was undertaken to provide an up-to-date analysis of the current prevention literature. PubMed, Embase, CINAHL, and PsycINFO were searched for relevant English-language articles published from 1970 onward. Studies were eligible for the current systematic review if the interventions included pregnant and postpartum women and/or their support networks to prevent AEPs and FASD. Outcomes of interest included alcohol consumption, knowledge, contraceptive use, neonatal outcomes, family well-being or functioning, economics, and healthcare utilization outcomes. Thirty-four peer-reviewed studies met the inclusion criteria. Fifteen studies employed brief intervention (BI) methods, 6 used long-term/intensive strategies, and 5 were educational interventions. A further 3 studies assessed counseling approaches, 2 evaluated multicomponent interventions, and 3 assessed nutritional supplementation interventions. The current review identified variable results from available interventions to prevent alcohol use among pregnant and postpartum women. Preliminary evidence demonstrated that BIs may be effective among subgroups of pregnant women with higher initial alcohol consumption, those with partner involvement, and those who used alcohol and other substances concurrently. Some preliminary evidence relating to long-term interventions with pregnant women with polysubstance use emerged, specifically case management that not only focused on reduction in substance use, but also on addressing the complex interplay between health and social well-being of families. Overall, additional research is required to improve the effectiveness of preventative approaches during pregnancy and the postpartum period.

Cognitions and behaviors related to risk for alcohol-exposed pregnancies among young adult women

This study assessed alcohol and sex-related cognitions and behaviors, including alcohol-related sexual expectancies, descriptive norms, and protective behavioral strategies, associated with women's risk for an alcohol-exposed pregnancy. A national sample of young adults ages 18-20years was subset to women who were capable of pregnancy and sexually active (n = 422). The outcome was risk of alcohol-exposed pregnancy as determined by contraceptive status and heavy-episodic drinking. SAS version 9.4 was used to estimate logistic regression models. Alcohol-related sexual expectancies related to enhancement were significantly associated with increased odds of alcohol-exposed pregnancy risk. In contrast, women who reported the use of more safe sex (non-condom related) protective behavioral strategies (e.g., talk to partner about birth control use) were at decreased odds of alcohol-exposed pregnancy risk. Future interventions to reduce the risk of alcohol-exposed pregnancies should consider alcohol-related sexual expectancies and safer sex protective behavioral strategies as leverage points.

Applying Ethical Principles When Discussing Alcohol Use During Pregnancy.

Over the past 2 decades, more women in the United States are engaging in excessive alcohol use, including women of reproductive age. Consuming alcohol in amounts greater than recommended limits is associated with an increased risk for adverse health effects, such as breast cancer, hypertension stroke, spontaneous abortion, and infertility. No safe time, safe amount, or safe type of alcohol to consume during pregnancy has been identified. Contradictory beliefs about alcohol use, fear of stigmatization, and potential legal consequences can provide challenges for health care providers who communicate these risks to clients. Health care providers can help to prevent alcohol-related health issues, including alcohol-exposed pregnancies, by providing their clients with factual information about alcohol and health and client-centered options for reducing their health risks. Clinicians can use alcohol screening and brief intervention as a framework for applying the ethical principles of autonomy, veracity, beneficence, and nonmaleficence when talking with women in ways that are nonstigmatizing and supportive to help reduce their health risks and prevent alcohol-exposed pregnancies.

Alcohol use and problems among Latinas at risk of an alcohol-exposed pregnancy: The role of acculturation and interpersonal factors

Path analysis was used to examine the role of acculturation, helping relationships, partner status, age, and education on heavy drinking and alcohol problems among 119 Latina adults at risk of an alcohol-exposed pregnancy (AEP). Greater acculturation was positively related to more helping relationships and heavy drinking, and there was an indirect positive relationship between acculturation and alcohol problems. There was also a positive relationship between helping relationships and alcohol problems, and a negative relationship between helping relationships and being partnered. Knowledge of the mechanisms by which acculturation and interpersonal factors influence behavior change can inform potential targets for intervention among Latinas with AEP risk.
