Short-term health outcomes of newborn infants of substance-using mothers in Australia and New Zealand: A systematic review

Neonatal outcomes of pregnant women attending integrated and standard substance use treatment programs in Ontario, Canada

BACKGROUND

Substance use in pregnancy raises concern given its potential teratogenic effects. Given the unique needs of parenting people and the potential impact for developing children, specialized substance use treatment programs are increasingly being implemented for this population. Substance use treatment is associated with more positive neonatal outcomes compared with no treatment, however treatment models vary limiting our understanding of key treatment components/modelsFew studies have explored the influence of treatment model type (i.e., integrated treatments designed for pregnant clients compared with standard treatment models) and no studies have examined the influence of treatment model on neonatal outcomes using Canadian data.

METHOD

We conducted a population-based cohort study of clients who were pregnant when initiating integrated (n = 564) and standard (n = 320) substance use treatment programs in Ontario, Canada.

RESULTS

Neonatal outcomes did not significantly differ by treatment type (integrated or standard), with rates of adverse neonatal outcomes higher than published rates for the general population, despite receipt of adequate levels of prenatal care. While this suggests no significant impact of treatment, it is notable that as a group, clients engaged in integrated treatment presented with more risk factors for adverse neonatal outcomes than those in standard treatment. While we controlled for these risks in our analyses, this may have obscured their influence in relation to treatment type.

CONCLUSION

Findings underscore the need for more nuanced research that considers the influence of client factors in interaction with treatment type. Pregnant clients engaged in any form of substance use treatment are at higher risk of having children who experience adverse neonatal outcomes. This underscores the urgent need for further investment in services and research to support maternal and neonatal health before and during pregnancy, as well as long-term service models that support women and children beyond the perinatal and early childhood periods.

Barriers to women's disclosure of and treatment for substance use during pregnancy: A qualitative study

INTRODUCTION

The use of alcohol and or illicit drugs during pregnancy is a complex public health issue. There are many adverse short- and long-term health implications of substance use during pregnancy that can potentially affect the mother-foetal dyad. Although prevention and treatment options - such as counselling, pharmacotherapy, rehabilitation, support and case management and withdrawal management - are available, a range of barriers impedes women's ability to disclose their substance use, which limits access and engagement with available services.

OBJECTIVE

This research explored barriers women encountered in disclosing substance use and accessing substance use treatment in pregnancy.

METHODS

Participants were recruited from a longitudinal cohort study of people with a history of injecting drug use from metropolitan Melbourne. One-on-one in-depth interviews with 15 participants were conducted using a semi-structured interview guide. To be included in this study, participants must have reported a history of substance use during one or more of their pregnancies.

RESULTS

The fear of losing child custody associated with the involvement of the child protection services was one of the main barriers to disclosing substance use during pregnancy and accessing treatment and rehabilitation services. Other barriers including stigma and perceived limited treatment options impacted women in various ways.

CONCLUSION

Pregnancy is an important time for women and offers opportunities for service providers to support women who are using substances. While not all barriers can be removed, careful consideration of individual cases and circumstances may help service providers to tailor interventions that are likely to be more successful.

Estimating the Combined Effects of Natural and Built Environmental Exposures on Birthweight among Urban Residents in Massachusetts

Intrauterine growth has health implications both in childhood and adulthood. Birthweight is partially determined by prenatal environmental exposures. We aim to identify important predictors of birthweight out of a set of environmental, built environment exposures, and socioeconomic environment variables during pregnancy (i.e., fine particulate matter (PM2.5), temperature, greenness, walkability, noise, and economic indices). We included all singleton live births of mothers who resided in urban census block-groups and delivered in Massachusetts between 2001 and 2011 (n = 640,659). We used an elastic-net model to select important predictors of birthweight and constructed a multivariate model including the selected predictors, with adjustment for confounders. We additionally used a weighted quantile sum regression to assess the contribution of each exposure to differences in birthweight. All exposures were selected as important predictors of birthweight. In the multivariate model, lower birthweight was significantly associated with lower greenness and with higher temperature, walkability, noise, and segregation of the "high income" group. Treating the exposures individually, nighttime noise had the highest weight in its contribution to lower birthweight. In conclusion, after accounting for individual confounders, maternal environmental exposures, built environment exposures, and socioeconomic environment during pregnancy were important predictors of birthweight, emphasizing the role of these exposures in fetal growth and development.

The Relationship between Maternal Personality Disorder and Early Birth Outcomes: A Systematic Review and Meta-Analysis

(1) Background: Women with personality disorder are at risk of social and emotional problems which impact deleteriously on everyday functioning. Moreover, a personality disorder diagnosis has been established to have an adverse impact upon pregnancy outcomes and child health. Understanding this impact is critical to improving both maternal and child outcomes. This systematic review and meta-analysis will evaluate the contemporary evidence regarding these relationships. (2) Methods: Prospero and Cochrane were searched for any systematic reviews already completed on this topic. Academic Search Premier, CINAHL Complete, MEDLINE, PsycARTICLES, PsycINFO via the EBSCO host, and the Web of Science Core Collection were searched to include research articles published between 1980 and 2019. A total of 158 records were identified; 105 records were screened by reviewing the abstract; 99 records were excluded; 6 full text articles were assessed for eligibility; 5 records were included in the review. (3) Results: All the included studies reported on preterm birth. The meta-analysis indicates significant risk of preterm birth in women with personality disorder (overall odds ratio (OR) 2.62; CI 2.24–3.06; p < 0.01). Three studies reported on low birth weight, with the meta-analysis indicating a raised risk of low birth weight of the babies born to women with personality disorder (overall OR 2.00 CI 1.12–3.57 (p = 0.02)). Three studies reported on appearance, pulse, grimace, activity, and respiration (APGAR) score, with the meta-analysis of OR’s indicating a risk of low APGAR score in women with personality disorder (overall OR 2.31; CI 1.17–4.55; p = 0.02). (4) Conclusions: The infants of women with personality disorder are at elevated risk of preterm birth, low birth weight and low APGAR score.

Association of maternal attention deficit hyperactivity disorder and preterm birth: a cohort study

OBJECTIVE

Attention deficit hyperactivity disorder (ADHD) affects 3-7% of women of childbearing age. Whether ADHD is associated with an increased risk of preterm birth is unclear.

DESIGN

National register-based cohort study.

SETTING

Sweden.

POPULATION

Nulliparous women giving birth to singleton infants 2007-2014 (n = 377 381).

METHODS

Women were considered to have ADHD if they had been dispensed at least one prescription for ADHD medication, i.e. a central nervous system stimulant or non-stimulant drugs for ADHD, prior to, during or after pregnancy (2005-2014). Women with ADHD were compared with women without ADHD in regard to prevalence, severity and mode of onset of preterm birth. Logistic regression models were used, estimating adjusted odds ratios (aOR) with 95% confidence intervals (CI). Adjustments were made for maternal age and country of birth (model 1), and in addition for body mass index (BMI), education, alcohol or substance use disorders, and pre-gestational medical and psychiatric co-morbidity (model 2).

MAIN OUTCOME MEASURES

Preterm birth (<37 weeks).

RESULTS

During the study period, 6327 (1.7%) women gave birth and had ADHD according to our definition. These women had a higher rate of preterm birth compared with women without ADHD (7.3 versus 5.8%, aOR model 2: 1.17; 95% CI 1.05-1.30). ADHD was particularly associated with very (<32 weeks) preterm births, and associations were seen with both spontaneous and medically indicated onsets.

CONCLUSIONS

Women with ADHD (i.e. who had been dispensed ADHD medication at any time in 2005-2014) had an increased risk of preterm birth.

TWEETABLE ABSTRACT

Women with ADHD have a higher risk of preterm birth but most of it is due to modifiable risk factors.

Barriers and facilitators in antenatal settings to screening and referral of pregnant women who use alcohol or other drugs: A qualitative study of midwives' experience

BACKGROUND

Screening pregnant women for substance use is highly recommended in antenatal care settings. Although midwives provide routine screening for substance use and referral for treatment in pregnancy, little is known about the barriers and facilitators they experience.

AIM

The study explored barriers and facilitators experienced by midwives in antenatal settings to screening and referral of pregnant women who use alcohol or other drugs.

DESIGN/SETTING

A semi-structured interview was adopted to explore barriers and facilitators experienced by midwives in screening and referring pregnant women for alcohol or other drugs specialised services. Eighteen midwives were recruited from urban, regional and rural antenatal settings in Victoria. Interviews were tape recorded and transcribed verbatim. Themes were generated by thematic analysis, the process of identifying patterns within the data.

FINDINGS

Of the seven themes identified under barriers, five could be categorised as "institution and provider-related", namely: (i) lack of validated screening tool, (ii) inadequate support and training, (iii) discomfort in screening, (iv) lack of multidisciplinary team and specialised treatment in regional and rural areas, and (v) workload and limited consultation time. Conversely, two themes could be classified as 'client-related', namely (i) non- or partial-disclosure of substance use, and (ii) reluctance and non-adherence to referrals. All five themes under facilitators were "institution and provider-related." They are (i) a woman-centred philosophy of care, (ii) evidence of harms from substance use on neonates, (iii) experience and training, (iv) continuity of care, and (v) availability of multidisciplinary team and funding.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

To the best of our knowledge, this is the first study of its kind conducted in Victoria. This study not only adds to the limited body of knowledge on barriers experienced by midwives but also identifies facilitators in antenatal settings that promote screening and referral of pregnant women who use substance. Most of the barriers and facilitators are interrelated. Despite midwives' willingness to screen all pregnant women for substance use and provision of referral, they often felt limited in their capacity. Availability and accessibility to validated screening tool(s), in addition to regular, ongoing training for all midwives to maintain clinical competence and provide effective communication are imperative. Availability of a multidisciplinary team, funds and specialised care facilities such as detoxification and mental health services, especially in regional and rural areas, are necessary to effectively support at-risk pregnant women.
