Prenatal substance exposure: What predicts behavioral resilience by early adolescence?

Environmental Influence on Adolescent Resilience Development in Medellin Colombia

Objective: To know the influence of the environment (family functionality, social support and neighbourhood and school environment) on the development of adolescent resilience. Methods: Descriptive, correlational design. A total of 184 adolescents from six schools in the Aranjuez district of Medellín participated. Probabilistic, two-stage sampling. Five scales were used to collect data: 1) The child and youth resilience measurement scale; 2) The neighbourhood environment questionnaire; 3) The family cohesion and adaptability assessment scale; 4) The multidimensional scale of perceived social support; and 5) The school environment questionnaire. Data were analysed though SPSS 24v software. Results: a relationship was found between resilience and neighbourhood environment (rs = .324, p = .000), family functionality (rs = .380, p = .000), social support (rs = .456, p = .000) and school environment (rs = .353, p = .000). In addition, resilience was explained in 35.8 % by the neighbourhood environment (β = .20; p = .012), family functionality (β = .13; p = .090), social support (β = .30; p = .000) and school environment (β = .15; p = .064). Conclusion: Adolescent resilient behaviour is influenced by social support, family functioning, and school and neighbourhood environment, all external factors fostering self-regulation, as mentioned by Roy’s Nursing model.

Cannabis use during pregnancy and its relationship with fetal developmental outcomes and psychiatric disorders. A systematic review

INTRODUCTION

This study analyze factors associated to cannabis use in pregnant women, its perceived availability, its risk perception and the relationship between prenatal exposure to cannabis and developmental and mental disorders.

OBJECTIVES

We present a review of the literature on cannabis use among pregnant women. The objective is to analyze factors associated to cannabis use during pregnancy and assess the potential effects of prenatal exposure to cannabis on the development of the fetus and the mental health of those exposed.

METHODS

Systematic review of studies on the maternal use of cannabis and the relationship between early exposure and the development of psychiatric disorders in the PubMed database until July 2018 in English and Spanish with the following keywords: Marijuana, Cannabinoids, Mental disorders, Pregnancy, Prenatal Cannabis Exposure, Risk factors.

RESULTS

The use of cannabis among pregnant women is frequent but it has not been extensively researched. Prenatal exposure to cannabis may be associated with affective symptoms and ADHD.

CONCLUSIONS

Mental healthcare professionals who treat women during their fertile life need to be able to explain the relationship between prenatal exposure to cannabis and the presence of developmental and mental disorders.

Characterizing adverse prenatal and postnatal experiences in children

BACKGROUND

Prenatal and postnatal adversities, including prenatal alcohol exposure (PAE), prenatal exposure to other substances, toxic stress, lack of adequate resources, and postnatal abuse or neglect, often co-occur. These exposures can have cumulative effects, or interact with each other, leading to worse outcomes than single exposures. However, given their complexity and heterogeneity, exposures can be difficult to characterize. Clinical services and research often overlook additional exposures and attribute outcomes solely to one factor.

METHODS

We propose a framework for characterizing adverse prenatal and postnatal exposures and apply it to a cohort of 77 children. Our approach considers type, timing, and frequency to quantify PAE, other prenatal substance exposure, prenatal toxic stress, postnatal threat (harm or threat of harm), and postnatal deprivation (failure to meet basic needs) using a 4-point Likert-type scale. Postnatal deprivation and harm were separated into early (<24 months of age) and late (≥24 months) time periods, giving seven exposure variables. Exposures were ascertained via health records, child welfare records, interviews with birth parents, caregivers, and/or close family/friends.

RESULTS

Nearly all children had co-occurring prenatal exposures, and two-thirds had both prenatal and postnatal adversities. Children with high PAE were more likely to experience late postnatal adversities, and children with other prenatal substance exposure were more likely to have early postnatal deprivation. Postnatal adversities were more likely to co-occur.

CONCLUSION

This framework provides a comprehensive picture of a child's adverse exposures, which can inform assessment and intervention approaches and policy and will be useful for future research.

Adult consequences of prenatal drug exposure

Maternal drug use is not new but over the last few decades, the number of mothers using drugs of addiction has escalated to epidemic levels. These drugs are both legal (e.g. prescription medication) and illegal (e.g. heroin) and all will cross the placental barrier into the developing infant. The most immediate and obvious consequence of intra-uterine drug exposure is newborn withdrawal or the Neonatal Abstinence Syndrome (NAS) which is now, with prompt recognition and treatment, an uncommon cause of neonatal death. Thousands (if not millions) of adults most likely would have had a history of passive drug exposure during gestation and the outcomes of these people are unknown. Most are physically healthy and do not need extra medical attention but the effects of prenatal drug exposure may be subtle and extensive. Drug-use disorders are accompanied by a myriad of other adverse problems, including poverty, mental and physical health problems and inadequate parenting ability that may compound the negative effects of drugs. Emerging data suggest that vulnerability to health and neurocognitive issues are pervasive and long-lasting as are lifestyle issues. This review will address current evidence in this area and highlight the knowledge gaps that must be addressed in order to optimise the outcomes for this vulnerable and marginalised but rapidly expanding population of adults.

Urban Young Adults’ Adaptive Functioning

Research on the association between prenatal substance exposures and adaptive functioning among young adults is limited, with inconsistent conclusions. In a prospective longitudinal study of 138 urban young adults, prenatal substance exposures were identified at birth from maternal self-report, urine screens, and/or infant meconium. At follow-up between ages 18 and 24 years, masked interviewers assessed level of adaptive functioning, a composite indicator comprising five domains: education, housing, adolescent pregnancy, arrest history, and employment. A significant negative association was found between prenatal tobacco exposure and adaptive functioning, particularly among females with heavier exposure. This association with heavier, but not lighter, prenatal tobacco exposure is consistent with a neuroteratologic explanation, but other, non-biological explanations cannot be ruled out. No statistically significant associations were observed between prenatal cocaine, marijuana, or low-moderate alcohol exposure and young adult adaptive functioning.
