Infant Behaviors, Prenatal Cocaine Exposure, and Adult Intelligence.

Importance: Linking prenatal drug exposures to both infant behavior and adult cognitive outcomes may improve early interventions. Objective: To assess whether neonatal physical, neurobehavioral, and infant cognitive measures mediate the association between prenatal cocaine exposure (PCE) and adult perceptual reasoning IQ. Design, Setting, and Participants: This study used data from a longitudinal, prospective birth cohort study with follow-up from 1994 to 2018 until offspring were 21 years post partum. A total of 384 (196 PCE and 188 not exposed to cocaine [NCE]) infants and mothers were screened for cocaine or polydrug use. Structural equation modeling was performed from June to November 2023. Exposures: Prenatal exposures to cocaine, alcohol, marijuana, and tobacco assessed through urine and meconium analyses and maternal self-report. Main Outcomes and Measures: Head circumference, neurobehavioral assessment, Bayley Scales of Infant Development, Fagan Test of Infant Intelligence score, Wechsler Perceptual Reasoning IQ, Home Observation for Measurement of the Environment (HOME) score, and blood lead level. Results: Among the 384 mothers in the study, the mean (SD) age at delivery was 27.7 (5.3) years (range, 18-41 years), 375 of 383 received public assistance (97.9%) and 336 were unmarried (87.5%). Birth head circumference (standardized estimate for specific path association, -0.05, SE = 0.02; P = .02) and 1-year Bayley Mental Development Index (MDI) (standardized estimate for total of the specific path association, -0.05, SE = 0.02; P = .03) mediated the association of PCE with Wechsler Perceptual Reasoning IQ, controlling for HOME score and other substance exposures. Abnormal results on the neurobehavioral assessment were associated with birth head circumference (ß = -0.20, SE = 0.08; P = .01). Bayley Psychomotor Index (ß = 0.39, SE = 0.05; P < .001) and Fagan Test of Infant Intelligence score (ß = 0.16, SE = 0.06; P = .01) at 6.5 months correlated with MDI at 12 months. Conclusions and Relevance: In this cohort study, a negative association of PCE with adult perceptual reasoning IQ was mediated by early physical and behavioral differences, after controlling for other drug and environmental factors. Development of infant behavioral assessments to identify sequelae of prenatal teratogens early in life may improve long-term outcomes and public health awareness.

Motion Robust MR Fingerprinting Scan to Image Neonates With Prenatal Opioid Exposure.

PURPOSE: To explore whether MR fingerprinting (MRF) scans provide motion-robust and quantitative brain tissue measurements for non-sedated infants with prenatal opioid exposure (POE). STUDY TYPE: Prospective. POPULATION: 13 infants with POE (3 male; 12 newborns (age 7-65 days) and 1 infant aged 9-months). FIELD STRENGTH/SEQUENCE: 3T, 3D T1-weighted MPRAGE, 3D T2-weighted TSE and MRF sequences. ASSESSMENT: The image quality of MRF and MRI was assessed in a fully crossed, multiple-reader, multiple-case study. Sixteen image quality features in three types-image artifacts, structure and myelination visualization-were ranked by four neuroradiologists (8, 7, 5, and 8 years of experience respectively), using a 3-point scale. MRF T1 and T2 values in 8 white matter brain regions were compared between babies younger than 1 month and babies between 1 and 2 months. STATISTICAL TESTS: Generalized estimating equations model to test the significance of differences of regional T1 and T2 values of babies under 1 month and those older. MRI and MRF image quality was assessed using Gwet's second order auto-correlation coefficient (AC2) with confidence levels. The Cochran-Mantel-Haenszel test was used to assess the difference in proportions between MRF and MRI for all features and stratified by the type of features. A P value <0.05 was considered statistically significant. RESULTS: The MRF of two infants were excluded in T1 and T2 value analysis due to severe motion artifact but were included in the image quality assessment. In infants under 1 month of age (N = 6), the T1 and T2 values were significantly higher compared to those between 1 and 2 months of age (N = 4). MRF images showed significantly higher image quality ratings in all three feature types compared to MRI images. CONCLUSIONS: MR Fingerprinting scans have potential to be a motion-robust and efficient method for nonsedated infants. LEVEL OF EVIDENCE: 2 TECHNICAL EFFICACY STAGE: 1.

Prenatal cocaine exposure and self-reported behavioral adjustments from ages 12 to 21: environmental pathways.

BACKGROUND: In a birth-cohort study, we followed offspring with prenatal cocaine exposure (PCE) to investigate longitudinal associations of PCE with self-reported behavioral adjustment from early adolescence to emerging adulthood (EA). Environmental pathways (family functioning, non-kinship care, maltreatment) were specified as potential mediators of PCE. METHODS: Participants were 372 (190 PCE; 47% male), primarily Black, low socioeconomic status, enrolled at birth. Internalizing and externalizing behaviors were assessed using Youth Self-Report at ages 12 and 15 and Adult Self-Report at age 21. Extended random-intercept cross-lagged panel modeling was used to account for potential bidirectional relationships between internalizing and externalizing behaviors over time, examining potential mediators. RESULTS: Adjusting for covariates, significant indirect effects were found for each mediator at different ages. For family functioning, these were both internalizing (ß = 0.83, p = 0.04) and externalizing behaviors (ß = 1.58, p = 0.02) at age 12 and externalizing behaviors at age 15 (ß = 0.51, p = 0.03); for non-kinship care, externalizing behaviors at ages 12 (ß = 0.63, p = 0.02) and 15 (ß = 0.20, p = 0.03); and for maltreatment, both internalizing and externalizing behaviors at ages 15 (ß = 0.64, p = 0.02 for internalizing; ß = 0.50, p = 0.03 for externalizing) and 21 (ß = 1.39, p = 0.01 for internalizing; ß = 1.11, p = 0.01 for externalizing). Direct associations of PCE with internalizing and externalizing behaviors were not observed, nor cross-lagged relationships between internalizing and externalizing behaviors. CONCLUSIONS: Negative associations of PCE with behavioral adjustment persist into EA via environmental pathways, specifying intervention points to disrupt adverse pathways toward healthy development.

Motion robust MR fingerprinting scan to image neonates with prenatal opioid exposure.

BACKGROUND: A noninvasive and sensitive imaging tool is needed to assess the fast-evolving baby brain. However, using MRI to study non-sedated babies faces roadblocks, including high scan failure rates due to subjects motion and the lack of quantitative measures for assessing potential developmental delays. This feasibility study explores whether MR Fingerprinting scans can provide motion-robust and quantitative brain tissue measurements for non-sedated infants with prenatal opioid exposure, presenting a viable alternative to clinical MR scans. ASSESSMENT: MRF image quality was compared to pediatric MRI scans using a fully crossed, multiple reader multiple case study. The quantitative T1 and T2 values were used to assess brain tissue changes between babies younger than one month and babies between one and two months. STATISTICAL TESTS: Generalized estimating equations (GEE) model was performed to test the significant difference of the T1 and T2 values from eight white matter regions of babies under one month and those are older. MRI and MRF image quality were assessed using Gwets second order auto-correlation coefficient (AC2) with its confidence levels. We used the Cochran-Mantel-Haenszel test to assess the difference in proportions between MRF and MRI for all features and stratified by the type of features. RESULTS: In infants under one month of age, the T1 and T2 values are significantly higher (p<0.005) compared to those between one and two months. A multiple-reader and multiple-case study showed superior image quality ratings in anatomical features from the MRF images than the MRI images. CONCLUSIONS: This study suggested that the MR Fingerprinting scans offer a motion-robust and efficient method for non-sedated infants, delivering superior image quality than clinical MRI scans and additionally providing quantitative measures to assess brain development.

Cognitive and functional outcomes at age 21 after prenatal cocaine/polydrug exposure and foster/adoptive care.

OBJECTIVE: Prenatal cocaine exposure (PCE) has been linked to specific cognitive deficits and behavioral outcomes through early adolescence but there is little information on adult outcomes nor on the relationship of environmental interventions, such as foster/adoptive care, to outcomes. METHODS: At 21 years, data were available on 325 young adults, [163 PCE and 162 non-exposed (NCE)], primarily African-American, with low SES, who were followed from birth in a prospective longitudinal cohort study. Participants were administered the Wechsler Abbreviated Scale of Intelligence (WASI-II) and surveyed regarding high school completion, problematic substance use, and incarceration/probation history. In the PCE group, 32 remained in non-kinship foster/adoptive care (PCE/FA) from early in life (< 4 years) to 17 years. Group differences were examined through t-tests, MANOVA/ MANCOVA with post-hoc analyses, comparing outcomes and environmental correlates of young adults with PCE vs. NCE, as well as outcomes of PCE young adults in non-kinship foster/adoptive care (PCE/ FA) vs. PCE in birth/kinship care and NCE young adults. RESULTS: At 21 years, young adults with PCE had lower mean Full Scale (83.7 ± 10.4 vs. 87.3 ± 12.5, p < .01) and Perceptual Reasoning IQs (87.3 ± 11.5 vs. 91.4 ± 13.9, (p < .02), lower high school completion rates (75% vs. 86%, p < .02), and were marginally more likely to have been on probation than NCE young adults, but did not differ in Verbal IQ, self-report of problematic substance use or incarceration. Young adults with PCE in F/A had similar lower IQ scores but had better verbal skills and high school graduation rates that did not differ from NCE young adults (80.6 vs 86.2%, p > .05). They had higher drug exposure at birth and more experiences of maltreatment (p's < 0.05) but their home environment quality was better and lead levels lower (p's < 0.05) than those of young adults with PCE in birth/kinship care. CONCLUSIONS: Young adults with PCE had lower Perceptual Reasoning and Full-Scale IQ scores, independent of caregiving placement, compared to non-exposed young adults. Young adults with PCE placed in non-kinship foster/adoptive care had lower lead levels, more stimulating home environments, better vocabulary skills and were more likely to graduate from high school than those in birth/kinship care,but were not different in their self-report of problematic substance use, or experiences of incarceration or probation. Our data suggest that some cognitive deficits observed in young adults with PCE may be biologically based, but that some functional outcomes can be modified through environmental interventions. Our data also reflect the complexity of disentangling the effects of teratologic exposures on long term outcomes across a variety of domains and the need for studies of children in the foster care system.

Prenatal cocaine exposure and substance use disorder in emerging adulthood at age 21.

BACKGROUND: Prenatal cocaine exposure (PCE) has been associated with child and adolescent externalizing behaviors and early substance use, yet few studies investigated its association with substance use disorder (SUD) in emerging adults. The present study examined the association of PCE with SUD in emerging adulthood, and whether childhood externalizing behaviors and adolescent substance use mediated the relationship. METHODS: Participants were 367 (187 PCE; 53% female) adults at age 21, primarily urban African American who were recruited at birth. PCE and exposure to alcohol, tobacco, and marijuana were determined using biologic assays for drug metabolites and/or maternal self-report at birth. Offspring externalizing problems were assessed using the Youth Self-Report at age 12, substance use and substance use-related problems via biologic assays and/or self-report at age 15, and SUD determined using DSM-5 diagnostic criteria at age 21. RESULTS: About 32.3% of the emerging adults were determined to have marijuana use disorder, 30.3% tobacco use disorder, and 15.5% alcohol use disorder. PCE was related to greater externalizing behaviors at age 12 (ß = 0.12, p = .042), which in turn was related to SUD (ß = 0.22, p = .008). PCE was also related to substance use, mainly marijuana, at age 15 (ß = 0.22, p = .011), which was related to SUD (ß = 0.51, p < .001). Total indirect effects including these two pathways were significant (ß = 0.19, p = .002). CONCLUSIONS: PCE may increase risk for SUD in emerging adulthood through childhood externalizing behaviors and adolescent substance use.

The association of prenatal cocaine exposure with expressive and receptive language skills, phonological processing and reading ability at age 17.

OBJECTIVE: Prenatal cocaine exposure (PCE) has been associated with small but significant effects on language development in childhood and early adolescence. This study examined whether this association persists into later adolescence and what relationship language skills may have with reading proficiency in this population. METHODS: Enrolled were 338 (167 with PCE, 171 with NCE or no cocaine exposure) 17-year-olds recruited at birth who, together with their current caregiver, were seen as part of a 17-year follow-up. Participants were given assessments of reading achievement (WIAT-III), receptive and expressive language (CELF-IV), and phonological processing (CTOPP). Relationships between PCE status and language outcomes were modeled using multiple linear regression controlling for environmental and caregiver factors, and other prenatal substance exposures. RESULTS: Adolescents with PCE scored lower in areas of phonological processing and reading related skills compared to adolescents with NCE. PCE by sex interactions were identified on language, memory and spoken language comprehension, with lower scores for girls with PCE compared to girls with NCE. CONCLUSION: These findings suggest the persistence of PCE's relationship with phonological awareness well into adolescence. PCE was also associated with lower scores on measures of skills related to reading ability, which may be a manifestation of the observed deficits in phonological processing.

Self-reported mental health outcomes in prenatally cocaine exposed adolescents at 17 years of age.

OBJECTIVE: Adverse developmental effects of prenatal cocaine exposure (PCE) are hypothesized to extend into late adolescence, yet few studies have investigated the association between PCE and late adolescent mental health outcomes. We examined the associations between PCE and self-reported mental health symptoms at age 17, controlling for biologic and environmental confounders. We further explored the potential moderating role of sex and the mediating role of earlier drug use by age 15 in the associations. METHOD: 327 (162 PCE; 165 non-cocaine exposed, NCE) urban adolescents, primarily African Americans, of low socioeconomic status, were prospectively recruited at birth for a longitudinal study and participated in the current study. We administered the Computerized Diagnostic Interview Schedule for Children-IV to assess their mental health symptoms at age 17. Alcohol, tobacco, and marijuana use by age 15 were assessed using biologic samples and self-reports. Confounders included other prenatal drug exposures, caregiving environment, and childhood maltreatment. RESULTS: Although no overall associations between PCE and mental health outcomes were observed, multivariate logistic regression models indicate girls with PCE were 3.60 times (95% CI = 1.45-8.96, p = .006) more likely to have symptoms of oppositional defiance disorder than girls with NCE. This relationship was partially mediated by marijuana use by age 15. CONCLUSION: Continued studies into emerging adulthood will further elucidate the long-term mental health outcomes associated with PCE.

Substance use and individual assets in urban adolescents: Subgroups and correlates in emerging adulthood.

INTRODUCTION: To investigate patterns of divergence in adolescent adjustment, this study examined the co-occurring patterns of adolescents' individual assets (e.g., school engagement, values) and substance use, and whether the co-occurring patterns were associated with later functioning in emerging adulthood. METHODS: Participants were 358 (54% females), predominantly African American, urban adolescents, recruited at birth for a prospective study on the effects of prenatal substance exposure in the Midwest United States. Individual assets, using the Developmental Assets Profile, substance use (alcohol, tobacco, marijuana), via biologic assays and self-report, and substance use-related problems were assessed at age 15 years. High-school completion, substance use disorder, mental health symptoms, and legal problems were assessed at age 21 years. RESULTS: Latent class analysis identified five classes as follows: high assets with low substance use (C1, 10.2%); moderate assets with low substance use (C2, 28.7%); low assets with low substance use (C3, 32%); moderate assets with high substance use (C4, 9.4%); and low assets with high substance use (C5, 19.2%). Despite similar levels of assets, adolescents in C5 reported more life adversities (suboptimal caregiving environment, daily hassles, non-birth parents' care) than those in C3. C4 and C5 reported more substance use disorder at age 21 years than the three low substance use classes; adolescents in C5 were less likely to complete high school than those in C2. More females in C5 reported greater mental health symptoms than those in C1 and C3, and criminal justice involvement than those in C1. CONCLUSIONS: The current findings underscore the significance of substance use in adolescence in disrupting healthy transition to adulthood, especially among females in the context of low individual assets.

Preschool blood lead levels, language competency, and substance use in adolescence.

BACKGROUND: Elevated lead levels in children are a persistent public health problem, particularly in urban areas in the United States, yet few prospective studies have examined the association of childhood lead levels with substance use in adolescence. OBJECTIVES: To determine the association of early lead levels with adolescent substance use and whether childhood IQ, language skills, and externalizing (aggressive and disruptive) behavior mediate the association, controlling for confounding biological and environmental factors. METHODS: The participants (N = 265) were a subsample of a prospective birth cohort study on the developmental effects of prenatal cocaine exposure in the Midwest United States. Blood lead levels (BLL) were assessed at age 4, IQ at age 11, language skills and externalizing behavior at age 12, and substance (alcohol, tobacco, marijuana) use and substance use-related problems at age 15. Biologic assays (hair, urine, bloodspots), along with self-report, were utilized to determine adolescent substance use. Path analyses were conducted to examine the direct and indirect associations of BLL with adolescent substance use. RESULTS: The children's mean BLL at 4 years of age was 7.07 (SD = 4.12) µg/dL. Approximately 31% of adolescents used tobacco or marijuana, 40% used alcohol, and 23% reported experiencing substance use-related problems at age 15.7 (SD = 0.28). Elevated BLL was related to a higher likelihood of substance use. Childhood language skills fully mediated the relationship of BLL with substance use-related problems. IQ was related to neither substance use nor substance use-related problems. DISCUSSION: Elevated BLL in preschool years is a risk factor for adolescent substance use and related problems. Early screening and intervention for language impairment may reduce substance use-related problems.

Association of fatty acid ethyl esters in meconium with behavior during childhood.

OBJECTIVE: To examine associations between amounts of fatty acid ethyl esters (FAEEs) in meconium and behavior in school aged children exposed to alcohol and drugs in utero. METHODS: A secondary analysis of a prospective cohort of cocaine, polydrug exposed children, primarily African-American, low socioeconomic status, recruited at birth into a longitudinal study. FAEEs were quantified with gas chromatography via a flame ionization detector. Meconium was analyzed for FAEEs for 216 newborns of whom 194 were assessed with the Child Behavior Checklist (CBCL) at ages 4, 6, 9, 10, 11, and 12. Generalized estimating equation analyses were used to assess the relationship of quantity of FAEEs to outcomes, controlling for maternal psychological distress. RESULTS: Higher concentrations of FAEEs (ethyl myristate, ethyl palmitate, ethyl oleate, ethyl linoleate, and ethyl linolenate) were associated with caregiver reported aggressive and/or delinquent behavior at ages 10 and 12. After control for caregiver psychological distress, and age, significant (p < 0.05) FAEE by age interactions were found for ethyl myristate for aggression and for ethyl oleate, ethyl linoleate and ethyl linolenate for delinquency. Thus, higher concentrations of FAEE were related to more caregiver reported aggressive and delinquent behaviors of clinical significance at ages 10 and 12. CONCLUSION: Higher concentrations of FAEEs in meconium are potential markers for children at risk for aggressive and delinquent behaviors related to the effects of prenatal alcohol exposure.

Fatty acid ethyl esters in meconium and substance use in adolescence.

Prenatal alcohol exposure (PAE) continues to be a serious public health problem, yet no reliable clinical tools are available for assessing levels of drinking during pregnancy. Fatty acid ethyl esters (FAEEs), the nonoxidative metabolites of ethanol measured in meconium, are potential biomarkers to quantify the level of PAE. The association between the concentrations of FAEEs from meconium and adolescent substance use and related problems was examined in a prospective birth-cohort of adolescents exposed to alcohol and drugs in utero. FAEEs were quantified with gas chromatography via a flame ionization detector. Meconium was analyzed for FAEEs in 216 newborns; 183 of them (81 boys, 102 girls) were assessed at age 15 for alcohol, tobacco, and marijuana use using biologic assays and self-report. Substance use problems were assessed using the Problem Oriented Screening Instrument for Teenagers. Findings from multivariable logistic regression analyses indicated that, after controlling for other prenatal drug exposure and covariates, higher concentrations of FAEEs (ethyl myristate, ethyl palmitate, ethyl oleate, ethyl linoleate, ethyl linolenate, and ethyl arachidonate) were related to a greater likelihood of marijuana use and experiencing substance use problems, but not tobacco or alcohol use, at age 15. Elevated levels of FAEEs in meconium may be promising markers for PAE, identifying newborns at risk for early substance use and developing substance use problems.

Prenatal Substance Exposure and Developmental Trajectories of Internalizing Symptoms: Toddlerhood to Preadolescence.

BACKGROUND: Little is known about how prenatal exposure to substances (alcohol, tobacco, marijuana, and cocaine) may contribute to heterogeneous childhood trajectories of internalizing symptoms (i.e., depression, withdrawal, anxiety). The present study aimed to identify developmental trajectories of internalizing symptoms in children using gender-separate analyses and to examine whether trajectories differ by prenatal substance exposure (PSE) and other environmental and biological correlates. METHODS: Data from two large community-based birth cohorts with PSE were integrated (N = 1,651, 848 boys, 803 girls): the Cleveland cohort and the Maternal Lifestyle Study (MLS). Internalizing symptoms were assessed with the Child Behavior Checklist at ages 2, 4, 6, 9, 10, 11, and 12 in the Cleveland study and at ages 3, 5, 7, 9, 11, and 13 in the MLS. RESULTS: Gender-separate group-based trajectory modeling yielded five distinctive developmental trajectories of internalizing symptoms from ages 2 to 13 in both boys and girls: low-risk group (14.4% girls, 28.8% boys); normative-decreasing group (35.3% girls, 33.1% boys); increasing risk group (14.4% girls, 13.0% boys); early-high group (22.3% girls, 17.9% boys); and chronic group (13.8% girls, 7.2% boys). Prenatal tobacco exposure, maternal psychological distress, and postnatal maternal alcohol use differentiated the longitudinal courses of internalizing symptoms. Boys were more likely to follow the low-risk trajectory, whereas girls were more likely to follow the chronic trajectory. CONCLUSIONS: Prenatal tobacco exposure was associated with suboptimal developmental trajectories of internalizing symptoms in the context of prenatal poly-drug exposure, highlighting a need for continued and increased effort toward prevention of prenatal tobacco use.

Best Practices for Engaging Pregnant and Postpartum Women at Risk of Substance Use in Longitudinal Research Studies: a Qualitative Examination of Participant Preferences.

There are significant barriers in engaging pregnant and postpartum women that are considered high-risk (e.g., those experiencing substance use and/or substance use disorders (SUD)) into longitudinal research studies. To improve recruitment and retention of this population in studies spanning from the prenatal period to middle childhood, it is imperative to determine ways to improve key research engagement factors. The current manuscript uses a qualitative approach to determine important factors related to recruiting, enrolling, and retaining high-risk pregnant and postpartum women. The current sample included 41 high-risk women who participated in focus groups or individual interviews. All interviews were analyzed to identify broad themes related to engaging high-risk pregnant and parenting women in a 10-year longitudinal research project. Themes were organized into key engagement factors related to the following: (1) recruitment strategies, (2) enrollment, and (3) retention of high-risk pregnant and parenting women in longitudinal research studies. Results indicated recruitment strategies related to ideal recruitment locations, material, and who should share research study information with high-risk participants. Related to enrollment, key areas disclosed focused on enrollment decision-making, factors that create interest in joining a research project, and barriers to joining a longitudinal research study. With regard to retention, themes focused on supports needed to stay in research, barriers to staying in research, and best ways to stay in contact with high-risk participants. Overall, the current qualitative data provide preliminary data that enhance the understanding of a continuum of factors that impact engagement of high-risk pregnant and postpartum women in longitudinal research with current results indicating the need to prioritize recruitment, enrollment, and retention strategies in order to effectively engage vulnerable populations in research.

Fifty Years of Research on Prenatal Substances: Lessons Learned for the Opioid Epidemic.

Current efforts to design research on developmental effects of prenatal opioid exposure can benefit from knowledge gained from 50 years of studies of fetal alcohol and prenatal drug exposures such as cocaine. Scientific advances in neurobiology, developmental psychopathology, infant assessments, genetics, and imaging support the principles of developmental neurotoxicology that guide research in prenatal exposures. Important to research design is accurate assessment of amount, frequency, and timing of exposure which benefits from accurate self-report and biomarkers of exposure. Identifying and control of pre- and postnatal factors that impact development are difficult and dependent on appropriate research design and selection of comparison groups and measurement of confounding, mediating, and moderating variables. Polysubstance exposure has increased due to the number of prescribed and nonprescribed substances used by pregnant women and varying combinations of drugs may have differential effects on the outcome. Multiple experimental and clinical assessments of infant behavior have been developed but predicting outcome before 18-24 months of age remains difficult. With some exceptions, prenatal substance exposure effect sizes have been small, and cognitive and behavioral effects tend to be specific rather than global. Studies require large sample sizes, adequate retention, and support for social services in at-risk samples. The ethical and legal contexts and stigma associated with drug/alcohol use disorder should be considered in order to prevent harm to families in research programs. Recognition of the pervasive use of addictive substances in this nation should lead to broad scientific efforts to understand how substances affect child outcomes and to initiate prevention and intervention where needed.

Cognitive and Behavioral Impact on Children Exposed to Opioids During Pregnancy.

The developmental impact of opioid use during pregnancy is a subject of ongoing debate. Short-term neonatal outcomes, such as lower birth weight and neonatal abstinence syndrome, are the most well-recognized outcomes. However, knowledge gaps exist regarding longer-term neurocognitive and mental health outcomes. In this article, we summarize an expert panel discussion that was held in April 2018 by the Substance Abuse and Mental Health Services Administration and attended by national experts in the field of perinatal opioid exposure and its impact on child development. Despite the challenges with research in this area, there is emerging literature revealing an association between neonates exposed to opioids in utero and longer-term adverse neurocognitive, behavioral, and developmental outcomes. Although adverse sequalae may not be apparent in the neonatal period, they may become more salient as children develop and reach preschool and school age. Multiple variables (genetic, environmental, and biological) result in a highly complex picture. The next steps and strategies to support families impacted by opioid use disorder are explored. Model programs are also considered, including integrated care for the child and mother, parenting supports, and augmentations to home visiting.

Profiles of individual assets and mental health symptoms in at-risk early adolescents.

INTRODUCTION: Few studies investigated the combined patterns of individual assets (e.g., social competence, positive identity) and mental health symptoms (MHS) in adolescents. This study examined the patterns of early adolescents' individual assets and MHS and whether identified patterns were associated with later adolescents' outcomes. METHODS: Participants were 352 (164 boys, 188 girls) adolescents who were primarily African-American and from low socioeconomic status families, participating in a prospective study of the effects of prenatal cocaine exposure from birth in the Midwest United States. Individual assets, using the Developmental Assets Profile, and MHS, using the Youth Self-Report, were assessed at age 12. Substance use, via self-report and biologic assays, early (before age 15) sexual behaviors, and behavioral adjustment were assessed at age 15. RESULTS: Latent profile analysis indicated four distinctive profiles: low assets with elevated MHS (P1, n = 54, 15.3%); adequate assets with thought and social problems (P2, n = 84, 23.9%); low assets without MHS (P3, n = 101, 28.7%); and high assets without MHS (P4, n = 113, 32.1%). Children in the profile with high assets without MHS (P4) were more likely to have a higher IQ and to be in a more optimal environment (higher parental monitoring and less family conflict) than those in other profiles. Although profiles with MHS were associated with adolescent risk behaviors, this relationship was more pronounced for girls than for boys. CONCLUSIONS: Girls in the low assets with elevated MHS (P1) should be a primary concern for preventive intervention. Our study demonstrates the heterogeneity of individual patterns of adaptation and maladaptation.
