The Protective Effect of Pregnancy on Risk for Drug Abuse: A Population, Co-Relative, Co-Spouse, and Within-Individual Analysis

Unique influences of pregnancy and anticipated parenting on cigarette smoking: results and implications of a within-person, between-pregnancy study

Not all pregnant individuals want to become parents and "parenting intention" can also vary within individuals during different pregnancies. Nevertheless, the potential impact of parenting intention on health-related behavior during pregnancy has been heavily underexplored. In this study, we employed a within-person between pregnancy design to estimate the effect of parenting-specific influences on smoking, separate from pregnancy-specific and individual-level influences. We quantified within-mother differences in smoking during pregnancies of infants they reared (n = 84) versus pregnancies of infants they placed for adoption at birth (n = 65) using multivariate mixed-effects Poisson regression models. Mean cigarettes/day declined as the pregnancy progressed regardless of whether infants were reared or placed. However, participants smoked fewer cigarettes/day during reared pregnancies. Relative to "adopted" pregnancies, smoking during "reared" pregnancies was lower by 24%, 41%, and 54% in first (95% CI 0.64-0.90; p = 0.001), second (95% CI 0.48-0.72; p < 0.001), and third trimesters (95% CI 0.36-0.59; p < 0.001), respectively, independent of between-pregnancy differences in maternal age, fetal sex, parity, and pregnancy complications. Female sex and nulliparity were protective. Parenting intention was associated with a protective effect on pregnancy smoking independent of pregnancy-specific influences and individual characteristics. Failure to consider the impact of parenting intention on health-related behavior during pregnancy could perpetuate an unrealistic expectation to "do what's best for the baby" and stigmatize women with unintended or unwanted pregnancies.

The Elephant in the Room: A Systematic Review of the Application and Effects of Psychological Treatments for Pregnant Women with Dual Pathology (Mental Health and Substance-Related Disorders)

PURPOSE

Maternal mental health and substance use, referred to as dual pathology, represent significant concerns associated with adverse pregnancy and birth outcomes, a prevalence higher than commonly anticipated. Nonetheless, a notable dearth exists ofevidence-based treatment protocols tailored for pregnant women with dual pathology.

METHODS

A systematic review, adhering to the PRISMA methodology, was conducted.

RESULTS

Out of the 57 identified papers deemed potentially relevant, only 2were ultimately included. Given the limited number of studies assessing the efficacy of psychological interventions utilizing randomized controlled trials (RCTs) for both mental health and substance misuse, and considering the diverse objectives and measures employed, definitive conclusions regarding the effectiveness of psychological interventions in this domain prove challenging.

CONCLUSIONS

Maternal mental health appears to be the proverbial "elephant in the room". The development of specialized and integrated interventions stands as an imperative to effectively address this pressing issue. As elucidated in the present review, these interventions ought to be grounded in empirical evidence. Furthermore, it is essential that such interventions undergo rigorous evaluation through RCTs to ascertain their efficacy levels. Ultimately, the provision of these interventions by psychology/psychiatric professionals, both within clinical practice and the RCTs themselves, is recommended to facilitate the generalizability of the results to specialized settings.

Interconnections between unintended pregnancy, alcohol and other drug use, and pregnancy, birth, infant, childhood and socioeconomic outcomes: a scoping review

BACKGROUND

Unintended pregnancy (UIP) and substance use disorder share underlying root causes with similar impacts for women and their offspring in pregnancy, birth and beyond. Furthermore, intoxication with alcohol and other drugs (AOD) increases the risk of UIP.

OBJECTIVES

To assess the available evidence on associations between UIP and health, social and economic outcomes, in women who use AOD.

SEARCH STRATEGY

The review utilised the Joanna Briggs Institute Methodology for Scoping Reviews and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The search was conducted across multiple databases, including Scopus and Medline, and limited to studies published between January 2000 to June 2023.

SELECTION CRITERIA

Studies reporting on interactions between AOD use and UIP, and pregnancy, birth, infant, childhood, social or economic outcomes. All patterns and types of AOD use, except isolated use of tobacco, were included. Studies were available in English and conducted in high-income countries.

DATA COLLECTION AND ANALYSIS

Selected articles were reviewed, and data collected by two independent reviewers using a standardised data extraction sheet. Findings were summarised and reported descriptively.

MAIN RESULTS

A total of 2536 titles and abstracts were screened, 97 full texts were reviewed, and three studies were selected for inclusion in the scoping review. There was heterogeneity in types and patterns of AOD use, differences in study design and tools to assess pregnancy intention, and each focused on disparate outcomes. No study assessed or reported on birth outcomes.

CONCLUSION

There is a paucity of data examining the intersection between AOD use and UIP and further research is needed.

"I just want the best for him." Pregnancy in the context of substance use disorders: Perspectives of postpartum women

BACKGROUND

In the United States, the incidence of substance misuse among pregnant women has been steadily increasing. While pregnant women with substance use disorder (SUD) are in critical need of support during the prenatal period, they enter prenatal care stigmatized and facing the possibility of punitive responses. Little research has been done about how women with SUDs themselves experience pregnancy and the transition to motherhood. The aim of this study was to examine women's internal experiences of pregnancy in the context of SUD.

METHODS

Semi-structured interviews were conducted with n = 19 postpartum women with SUD. Data were analyzed using a semantic, thematic approach.

RESULTS

Participants expressed their thoughts and experiences about their pregnancies in four main themes: (1) fear of harming the baby; (2) fear about child welfare involvement; (3) guilt informed by recovery stage; and (4) mixed feelings about pregnancy amidst complicated circumstances. The women expressed fear about their children's well-being, coupled with motivation to protect their child and the need for clear medical information. Their expressions of guilt depended on the severity of their SUD and their stage in recovery during their pregnancy. Women entered prenatal care with mixed emotions about their pregnancy, such as guilt and excitement, in the midst of complicated life circumstances.

CONCLUSIONS

These findings suggest a complexity of internal experiences for pregnant women with SUDs. Participants' feelings and experiences during pregnancy can inform practitioners' approaches to prenatal care in the context of SUDs.

Sex/Gender Differences in the Time-Course for the Development of Substance Use Disorder: A Focus on the Telescoping Effect

Sex/gender effects have been demonstrated for multiple aspects of addiction, with one of the most commonly cited examples being the "telescoping effect" where women meet criteria and/or seek treatment of substance use disorder (SUD) after fewer years of drug use as compared with men. This phenomenon has been reported for multiple drug classes including opioids, psychostimulants, alcohol, and cannabis, as well as nonpharmacological addictions, such as gambling. However, there are some inconsistent reports that show either no difference between men and women or opposite effects and a faster course to addiction in men than women. Thus, the goals of this review are to evaluate evidence for and against the telescoping effect in women and to determine the conditions/populations for which the telescoping effect is most relevant. We also discuss evidence from preclinical studies, which strongly support the validity of the telescoping effect and show that female animals develop addiction-like features (e.g., compulsive drug use, an enhanced motivation for the drug, and enhanced drug-craving/vulnerability to relapse) more readily than male animals. We also discuss biologic factors that may contribute to the telescoping effect, such as ovarian hormones, and its neurobiological basis focusing on the mesolimbic dopamine reward pathway and the corticomesolimbic glutamatergic pathway considering the critical roles these pathways play in the rewarding/reinforcing effects of addictive drugs and SUD. We conclude with future research directions, including intervention strategies to prevent the development of SUD in women. SIGNIFICANCE STATEMENT: One of the most widely cited gender/sex differences in substance use disorder (SUD) is the "telescoping effect," which reflects an accelerated course in women versus men for the development and/or seeking treatment for SUD. This review evaluates evidence for and against a telescoping effect drawing upon data from both clinical and preclinical studies. We also discuss the contribution of biological factors and underlying neurobiological mechanisms and highlight potential targets to prevent the development of SUD in women.

Marijuana use, fetal growth, and uterine artery Dopplers

OBJECTIVE

Marijuana (MJ) use is associated with adverse effects on fetal growth. We aimed to investigate the timing of suboptimal fetal growth onset in MJ-exposed pregnancies. In addition, we aimed to explore the relationship between MJ-exposure and both abnormal uterine artery (UtA) Doppler parameters and small for gestational age (SGA).

STUDY DESIGN

This was a secondary analysis of a prospective multicenter cohort that enrolled nulliparous individuals delivering non-anomalous fetuses beyond 20 weeks' gestation. Marijuana exposure was ascertained by self-report or clinical urine toxicology testing. Ultrasound estimated fetal weights (EFWs) were assessed in participants at both 16w0d-21w6d and 22w0d-29w6d. EFWs and birth weight (BW) were converted to weight percentiles (wPCT). EFW and BW wPCTs were calculated using population-based standards. Additionally, a customized standard designed to be applicable to both EFWs and BWs within the same model was also used to allow for EFW to BW percentile trajectories. The primary outcome, longitudinal wPCT, was compared between individuals with and without MJ use in a linear mixed-effects regression model adjusting for tobacco. For modeling, wPCT was smoothed across gestational age; MJ was estimated as an intercept and linear difference in the slope of gestational age. UtA Doppler notching, resistance index (RI), and pulsatility index (PI) at 16w0d-21w6d were compared using t-test and χ2. SGA at delivery was also compared.

RESULTS

Nine thousand one hundred and sixty-three individuals met inclusion criteria; 136 (1.5%) used MJ during pregnancy. Individuals who used MJ were more likely to be younger, identify as non-Hispanic Black, and have had less education. Fetuses exposed to MJ had lower wPCT beginning at 28 weeks using population-based and customized standards, when compared to those without exposure. UtA notching, PI, and RI were similar between groups. SGA was more frequent in neonates exposed to MJ using both population-based (22 vs. 9%, p<.001) and customized (25 vs. 14%, p<.001) curves.

CONCLUSIONS

MJ-exposed fetuses were estimated to be smaller than unexposed fetuses starting at 28 weeks' gestation across both growth standards without a difference in UtA Doppler parameters.

Within-person decline in pregnancy smoking is observable prior to pregnancy awareness: Evidence across two independent observational cohorts

Decreased consumption of nicotine and other drugs during pregnancy appears to be a cross-species phenomenon from which mechanism(s) capable of interrupting addictive processes could be elucidated. Whether pregnancy influences smoking behaviour independent of women's knowledge of the pregnancy, however, has not been considered. Using repeated measures analysis of variance (ANOVA), we estimated within-person change in mean cigarettes/day smoked across the estimated date of conception but prior to individually reported dates of pregnancy recognition using longitudinal smoking data from two independent observational cohorts, the Growing Up Healthy (GUH, n = 271) and Midwest Infant Development Studies (MIDS, n = 145). Participants smoked an average of half a pack/day in the month immediately before conception (M (SD) = 12(8.1) and 9.5(6.7) cigarettes/day in GUH and MIDS, respectively). We observed within-person declines in smoking after conception, both before (MGUH  = -0.9; 95% CI -1.6, -0.2; p = 0.01; MMIDS  = -1.1; 95% CI -1.9, -0.3; p = 0.01) and after (MGUH  = -4.8; 95% CI -5.5, -4.1; p < 0.001; MMIDS  = -3.3; 95% CI -4.4, -2.5; p < 0.001) women were aware of having conceived, even when women who had quit and women who were planning to conceive were excluded from analyses. Pregnancy may interrupt smoking-related processes via mechanisms not previously considered. Plausible candidates and directions for future research are discussed.

Are empathic processes mechanisms of pregnancy's protective effect on smoking? Identification of a novel target for preventive intervention

BACKGROUND

Spontaneous cessation and reduction in smoking by pregnant women suggest that concern about others, or empathy, could be a malleable target for intervention. We examined various empathy-related processes in relations to reported and biochemically assessed smoking during pregnancy.

METHODS

Participants were 154 pregnant women (M = 12.4 weeks gestation, SD = 4.6) who were smoking cigarettes immediately prior to pregnancy recognition (85 had quit and 69 were still smoking at enrollment). Empathy-related processes were measured with performance-based paradigms (affect sharing, empathic concern, and theory of mind) and a speech sample (expressed emotion). Smoking was assessed with timeline follow back interviews and urine cotinine assays. Using zero-inflated Poisson regression models, we tested direct and interactive effects of empathy-related processes with respect to biologically verified smoking cessation (zero portion); and mean cigarettes/day smoked after pregnancy recognition among persistent smokers (count portion).

RESULTS

Affect sharing was inversely related to post-recognition cigarettes/day (B(SE) = -0.17(0.07), 95%C.I. -0.30,-0.04, p = .011) and moderated the relationship between pre-recognition smoking and post-recognition smoking consistent with a buffering effect (B(SE) = -.17(0.05); 95%C.I. - 0.28,-0.06; p = .002). Other empathy related processes showed neither direct nor interactive effects on smoking outcomes.

CONCLUSIONS

Further research is recommended to clarify the role of empathy in pregnancy smoking.

Nurturing families: One year pilot outcomes for a modified Parent Child Assistance Program in Australia

Alcohol and Other Drug (AOD) exposure during pregnancy is linked to serious adverse child outcomes, including Fetal Alcohol Spectrum Disorder (FASD). The Parent-Child Assistance Program (PCAP) supports women with problematic AOD use, who are pregnant or have young children, and are not effectively engaging with services. PCAP has been shown to reduce alcohol exposed pregnancies, promote AOD abstinence, increase employment and family planning and improve child outcomes. This manuscript reports the first pilot evaluation of the PCAP program delivered in Australia. A pre-post-intervention repeated measures design was used. Eleven women receiving PCAP from a not-for-profit organisation were invited to take part in the study, with eight providing complete pre-post data. Home visitation case management was provided by trained and experienced case-managers. Clients were assisted to engage with existing services effectively to meet their own goals via a combination of relational theory, motivational interviewing and harm reduction concepts. The PCAP Modified Addiction Severity Index 5th Edition was adapted for use in Australia and was used to measure domains of addiction severity related problems as the primary outcome. Secondary outcomes included client satisfaction and program fidelity. There were significant changes in composite addiction severity scores from baseline to one year. 80% of participants had periods of abstinence of longer than four months. All clients had better connection to services, no subsequent AOD exposed pregnancies, and were highly satisfied with the program. Four had children returned to their care. Implementation was similar to the original PCAP program with major differences including case-managers relying on training manuals only without undertaking in-person training; being more experienced; providing more direct AOD counselling; and having less supervision. The findings will inform future program delivery and methodology for a larger longitudinal study assessing outcomes at program exit.

Mental disorders during the perinatal period: Results from a nationally representative study

OBJECTIVE

This study examined mental health profiles of pregnant and postpartum females, with and without perinatal complications, compared to non-perinatal females of childbearing age.

METHODS

We analyzed nationally representative data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309; 51.9% female). A validated semi-structured interview assessed past-year DSM-5 mental disorders. Multivariable regressions examined associations between perinatal status and mental disorders, controlling for sociodemographic characteristics.

RESULTS

Using females who were not pregnant in the past year as a reference group, those who were postpartum with complications during pregnancy or delivery had increased odds of any past-year mental disorder (58.7% vs. 46.8%; AOR = 1.56), any depressive/bipolar disorder (26.4% vs. 18.8%; AOR = 1.57), and posttraumatic stress disorder (14.0% vs. 7.3%; AOR = 1.99). In contrast, those who were postpartum without complications did not have increased odds of these disorders. Those who were pregnant without pregnancy complications had reduced odds of any past-year mental disorder (33.7% vs. 46.8%; AOR = 0.55) and any depressive/bipolar disorder (11.7% vs. 18.8%; AOR = 0.60). All perinatal groups had reduced odds of any substance use disorder compared to those who were not pregnant in the past year (18.9-25.7% vs. 29.8% AORs: 0.49-0.78), except those who were postpartum with pregnancy or delivery complications (28.8%).

CONCLUSION

Results highlight the importance of mental health screening among perinatal females, particularly those who are postpartum and experience perinatal complications. Findings may inform the development of targeted interventions for this subpopulation.

Continuation in Treatment and Maintenance of Custody of Newborns After Delivery in Women With Opioid Use Disorder

OBJECTIVE

To identify variables associated with continuation in treatment and maintenance of custody after pregnancies in women with opioid use disorder (OUD).

METHODS

The medical records of pregnant women with documented OUD from 2011 to 2018 and with at least 6 months follow-up postpartum were retrospectively reviewed.

RESULTS

Via multivariate analysis, women on opioid maintenance therapy (OMT) were more likely to continue in treatment and maintain custody, whereas women enrolled in a residential treatment program during pregnancy were less likely to continue in treatment or maintain custody. Women who continued in treatment were significantly more likely to maintain custody of their children than those who did not.

CONCLUSIONS

Continuation in treatment and maintenance of custody were closely related. Care providers should attempt to improve both outcomes.

Screening for Mental Health and Substance Use Disorders in Obstetric Settings

PURPOSE OF REVIEW

The objective of this review is to describe the extent to which (1) obstetric settings are currently screening for mental health and substance use disorders and social determinants of health (SDoH), and (2) screening is followed by systematic approaches for ensuring an adequate response to positive screens. Additionally, clinical and policy implications of current screening practices and recommendations are discussed.

RECENT FINDINGS

Screening for perinatal depression in obstetric settings has increased. Despite their prevalence and negative impact, screening for other mental health and substance use disorders and SDoH is much less common and professional society recommendations are either nonexistent, less consistent, or less prescriptive. To truly address maternal mental health, we need to move beyond focusing solely on depression and address other mental health and substance use disorders and the contextual social determinants in which they occur.

Abstinence outcomes among women in reproductive health centers administered clinician or electronic brief interventions

Treatment of substance use in women seeking reproductive healthcare is crucial for the health of both women and their offspring. Although abstinence from all substance use during pregnancy is optimal, it is difficult to achieve. This secondary analysis reports abstinence outcomes from a randomized clinical trial of screening, brief intervention, and referral to treatment (SBIRT) for substance use among women seeking reproductive healthcare services. Women who screened positive for substance use were randomly assigned to either clinician-administered SBIRT, an electronically-administered brief intervention (e-SBIRT), or an enhanced usual care condition. At a 6-month follow-up assessment, compared to enhanced usual care, the clinician-administered SBIRT increased 1-month point prevalence of abstinence from the primary substance by 7.7%, and e-SBIRT increased abstinence by 12.8%. Both brief interventions were more useful than enhanced usual care and could increase substance use abstinence rates among women in reproductive healthcare clinics. The electronic brief intervention is particularly attractive given that it appears as efficacious as, but requires fewer resources than, clinician-delivered brief interventions.

Maternal drug-related death and suicide are leading causes of postpartum death in California

BACKGROUND

Reducing maternal mortality is a priority in the United States and worldwide. Drug-related deaths and suicide may account for a substantial and growing portion of maternal deaths, yet information on the incidence of and sociodemographic variation in these deaths is scarce.

OBJECTIVE

We sought to examine incidence of drug-related and suicide deaths in the 12 months after delivery, including heterogeneity by sociodemographic factors. We also explored maternal decedents' health care utilization prior to death.

STUDY DESIGN

This retrospective, population-based cohort study followed up 1,059,713 women who delivered a live-born infant in California hospitals during 2010-2012 to ascertain maternal death. Analyses were conducted using statewide, all-payer, longitudinally-linked hospital and death data.

RESULTS

A total of 300 women died during follow-up, a rate of 28.33 deaths per 100,000 person-years. The leading cause of death was obstetric-related problems (6.52 per 100,000 person-years). Drug-related deaths were the second leading cause of death (3.68 per 100,000 person-years), and suicide was the seventh leading cause (1.42 per 100,000 person-years); together these deaths comprised 18% of all maternal deaths. Non-Hispanic white women, Medicaid-insured women, and women residing in micropolitan areas were especially likely to die from drugs/suicide. Two thirds of women who died, including 74% of those who died by drugs/suicide, made ≥1 emergency department or hospital visit between their delivery and death.

CONCLUSION

Deaths caused by drugs and suicide are a major contributor to mortality in the postpartum period and warrant increased clinical attention, including recognition by physicians and Maternal Mortality Review Committees as a medical cause of death. Importantly, emergency department and inpatient hospital visits may serve as a point of identification of, and eventually prevention for, women at risk for these deaths.

Parenting stress: A novel mechanism of addiction vulnerability

Addiction remains a significant public health concern. Despite numerous public health initiatives, many parents continue to use substances during the prenatal and postpartum period. While stress has been implicated in the maintenance of substance use disorders more generally, we propose that parenting stress specifically increases vulnerability to substance use in adults caring for young children. To explore this notion, we first consider the neurobiology of the adult transition to parenthood and the value of adopting a parenting-specific approach to understanding addictive processes. Next, we consider the neurobiology of addiction and parenting before directly addressing parenting stress in the context of addiction. Finally, we describe current interventions with parents that incorporate the management of negative affect to enhance caregiving quality and decrease substance use. Taken together, this article proposes that the unique demands of caring for a developing child may be more stressful above and beyond other forms of stress. As a consequence, intervention approaches that target stress in the parenting role hold promise for decreasing parental substance abuse.

Mental Disorders and Suicide Attempts in the Pregnancy and Postpartum Periods Compared with Non-Pregnancy: A Population-Based Study

OBJECTIVE

To compare the rate of mental disorders (i.e., mood and anxiety, substance use, psychotic disorders) and suicide attempts within the same group of women across the pre-pregnancy, pregnancy, and postpartum periods, and between this perinatal cohort and a non-perinatal reference group.

METHOD

Data were from an administrative repository of residents in Manitoba, Canada. The perinatal cohort consisted of women aged 18 to 45 years who experienced >1 live birth pregnancy between 2011 and 2014 (n = 45,362). Pre-pregnancy, pregnancy, and postpartum periods were defined over consecutive 40-week intervals. The non-perinatal cohort consisted of age-matched women with no pregnancies during the same period (n = 139,705). A reference 40-week interval was defined from the individual's birthdate in the year they entered the cohort. Rate ratios of diagnosed mental disorders were adjusted (aRR) for demographic factors, parity, and mental health history.

RESULTS

Within the perinatal cohort, pregnancy was associated with a lower rate of diagnosed mood or anxiety disorder, substance use disorder, and suicide attempt relative to pre-pregnancy (aRR range, 0.22-0.82). Pregnancy also had lower rates of all outcomes compared with the postpartum period (aRR, 0.44-0.87). Postpartum had a higher rate of psychotic disorder compared with pre-pregnancy (aRR, 1.61; 95% CI, 1.17-2.21), but a lower rate of mood or anxiety disorder and suicide attempt. Compared with non-perinatal women, pregnancy was associated with lower rates of all outcomes (aRR range, 0.25-0.87).

CONCLUSIONS

Compared with a non-perinatal period, the rate of a diagnosed mental disorder is lower during pregnancy but begins to rise in the postpartum period, highlighting an important period for early identification and rapid access to intervention.

Obstetric patients' perspectives on functional magnetic neuroimaging research in pregnant women

Magnetic resonance neuroimaging (MRI) studies of healthy pregnant women could identify key mechanisms of spontaneous health behavior changes observed in expectant mothers as novel intervention targets, but are currently unprecedented. As balancing potential benefits of research with unknown risks, including participant perceptions of risk, is foundational to ethical conduct, we surveyed a convenience obstetric sample to understand pregnant women's perspectives on this issue. Respondents were 76 pregnant women (modal age of 30-39 years; 64% multiparous) presenting for obstetric care from April to June 2016 at privately and publicly funded clinics at an urban academic medical center in the Midwestern USA. Following a written description about functional magnetic resonance neuroimaging (fMRI) and its known and unknown risks, women were queried on their willingness to participate in a hypothetical study involving fMRI during pregnancy, and specific concerns about doing so, if hesitant or unwilling. Willingness to participate was "yes" (28.4%, n = 21), "maybe" (28.4%, n = 21), and "no" (43.2%, n = 32). Among those responding "maybe" or "no" (n = 53, 73.6%), 11 women (20.7%) articulated concern about the fetus. Other concerns expressed were time commitment (n = 11, 20.7%) and discomfort being in an MRI machine (n = 4; 7.5%). Pregnant women may be open to participating in research involving MRI provided concerns about fetal health, time, and personal comfort are addressed.

Protective Effects of Pregnancy on Risk of Alcohol Use Disorder

OBJECTIVE

The authors sought to clarify the etiology of the association between pregnancy and reduced risk of alcohol use disorder.

METHODS

The authors used data from longitudinal population-wide Swedish medical, pharmacy, and criminal registries to evaluate whether rates of alcohol use disorder are lower during pregnancy. They compared pregnant women born between 1975 and 1992 (N=322,029) with matched population controls, with female relatives discordant for pregnancy, and with pre- and postpregnancy periods within individuals. They further compared rates of alcohol use disorder between pregnant women and their partners.

RESULTS

Pregnancy was inversely associated with alcohol use disorder across all analyses (odds ratios, 0.17-0.32). In co-relative analyses, the strength of the association increased among more closely related individuals. Within individuals, rates of alcohol use disorder were substantially decreased during pregnancy relative to the prepregnancy period (odds ratios, 0.25-0.26), and they remained reduced during postpartum periods (odds ratios, 0.23-0.31). Results were similar for second pregnancies (odds ratio, 0.23). The partners of pregnant women also exhibited reductions in alcohol use disorder (odds ratio, 0.45). Among women who became pregnant at earlier ages and those with a history of criminal behavior, the negative association between pregnancy and alcohol use disorder was especially pronounced, but no moderation was observed for a personal or maternal parental history of alcohol use disorder.

CONCLUSIONS

The findings suggest that pregnancy plays a critical, and likely causal, motivational role in reducing alcohol use disorder risk among women and, to a lesser extent, their partners. These results extend our understanding of the relationship between pregnancy and alcohol use, demonstrating that even a severe condition such as alcohol use disorder is subject to the protective effects of pregnancy.

Positive parenting behaviors in women who spontaneously quit smoking during pregnancy: Clues to putative targets for preventive interventions

BACKGROUND

While the majority of pregnant smokers do not respond to intervention, little is known about how a subset of pregnant smokers known as spontaneous quitters achieve sustained biologically-confirmed abstinence through delivery in the absence of intervention. We explore a developmental framework to address this question by viewing spontaneous quitting as an adaptive parenting behavior, facilitated by abilities necessary for sensitive parenting, or responsiveness. Utilizing existing data, we examined responsiveness from parenting assessments in women who exhibited a variety of smoking patterns during pregnancy, including spontaneous quitting.

METHODS

Participants were N = 305 pregnant women assessed for smoking prospectively and biochemically at 16 weeks, 28 weeks, delivery, and 4 weeks postpartum, then reassessed with their children 5 years later with directly-observed home- and lab-based measures of parenting. We used linear regression analysis to compare spontaneous quitters with women who exhibited other prenatal smoking patterns on parenting responsiveness, controlling for potential confounders.

RESULTS

In home-based observations, spontaneous quitters (n = 22) exhibited greater responsiveness with their children relative to intermittent pregnancy smokers [n = 70; β = 0.258, p = .022]; persistent pregnancy smokers [n = 66; β = 0.228, p = .040]; former smokers (quit before pregnancy) [n = 78; β = 266, p = .028]; and never smokers [n = 69; β = 0.312, p = .009]. Hypothesized differences were not observed in lab-based and self-report measures.

CONCLUSIONS

Putative protective characteristics in spontaneous quitters were captured in mother-child interactions at home, but not in lab-based and maternal report measures of responsiveness. Specification of these characteristics using prospective designs that oversample for spontaneous quitters is recommended to enable translation to preventive interventions.

The Impact of Early Substance Use Disorder Treatment Response on Treatment Outcomes Among Pregnant Women With Primary Opioid Use

OBJECTIVES

This study examined the impact of early patient response on treatment utilization and substance use among pregnant participants enrolled in substance use disorder (SUD) treatment.

METHODS

Treatment responders (TRs) and treatment nonresponders (TNRs) were compared on pretreatment and treatment measures. Regression models predicted treatment utilization and substance use.

RESULTS

TR participants attended more treatment and had lower rates of substance use relative to TNR participants. Regression models for treatment utilization and substance use were significant. Maternal estimated gestational age (EGA) and baseline cocaine use were negatively associated with treatment attendance. Medication-assisted treatment, early treatment response, and baseline SUD treatment were positively associated with treatment attendance. Maternal EGA was negatively associated with counseling attendance; early treatment response was positively associated with counseling attendance. Predictors of any substance use at 1 month were maternal education, EGA, early treatment nonresponse, and baseline cocaine use. The single predictor of any substance use at 2 months was early treatment nonresponse. Predictors of opioid use at 1 month were maternal education, EGA, early treatment nonresponse, and baseline SUD treatment. Predictors of opioid use at 2 months were early treatment nonresponse, and baseline cocaine and marijuana use. Predictors of cocaine use at 1 month were early treatment nonresponse, baseline cocaine use, and baseline SUD treatment. Predictors of cocaine use at 2 months were early treatment nonresponse and baseline cocaine use.

CONCLUSIONS

Early treatment response predicts more favorable maternal treatment utilization and substance use outcomes. Treatment providers should implement interventions to maximize patient early response to treatment.
