One-Day Peer-Delivered Cognitive Behavioral Therapy-Based Workshops for Postpartum Depression: A Randomized Controlled Trial.

INTRODUCTION: Myriad treatment barriers prevent birthing parents with postpartum depression (PPD) from receiving timely treatment. We aimed to determine whether a peer-delivered online 1-day cognitive behavioral therapy (CBT)-based workshop added to treatment as usual (TAU) improves PPD and its comorbidities and is more cost-effective than TAU alone. METHODS: This parallel-group, randomized controlled trial took place in Ontario, Canada (June 7, 2021, to February 18, 2022). Participants were ≥18 years old, had an infant ≤12 months old, and an Edinburgh Postnatal Depression Scale (EPDS) score ≥10. Participants were allocated to receive the workshop plus TAU (n = 202) or TAU and waitlisted to complete the workshop 12 weeks later (n = 203). The primary outcome was change in PPD (EPDS score) from enrollment to 12 weeks later. The secondary outcome was cost-effectiveness and tertiary outcomes included anxiety, social support, partner relationship quality, the mother-infant relationship, parenting stress, and infant temperament. RESULTS: Participants had a mean age of 32.3 years (SD = 4.30) and 65% were White. The workshop led to a significant reduction in EPDS scores (15.95-11.37; d = 0.92, p < 0. 01) and was associated with higher odds of exhibiting a clinically significant decrease in EPDS scores (OR = 2.03; 95% CI: 1.26-3.29). The workshop plus TAU was more cost-effective than TAU alone. It also led to improvements in postpartum anxiety, infant-focused anxiety, parenting stress, and infant temperament. CONCLUSIONS: Peer-delivered 1-day CBT-based workshops can improve PPD and are a potentially scalable low-intensity treatment that could help increase treatment access.

Screen Time and Socioemotional and Behavioural Difficulties Among Indigenous Children in Canada: Temps d'écran et difficultés socio-émotionnelles et comportementales chez les enfants autochtones du Canada.

OBJECTIVES: To describe screen time levels and determine their association with socioemotional and behavioural difficulties among preschool-aged First Nations, Métis, and Inuit children. METHOD: Data were taken from the Aboriginal Children's Survey, a nationally representative survey of 2-5-year-old Indigenous children in Canada. Socioemotional and behavioural difficulties were defined using parent/guardian reports on the Strengths and Difficulties Questionnaire. Multiple linear regression analyses were conducted separately for First Nations, Métis, and Inuit participants, and statistically adjusted for child age, child sex, and parent/guardian education. Statistical significance was set at P < 0.002 to adjust for multiple comparisons. RESULTS: Of these 2-5-year-old children (mean [M] = 3.57 years) 3,085 were First Nations (53.5%), 2,430 Métis (39.2%), and 990 Inuit (7.3%). Screen time exposure was high among First Nations (M = 2 h and 58 min/day, standard deviation [SD] = 1.89), Métis (M = 2 h and 50 min [SD = 1.83]), and Inuit children (M = 3 h and 25 min [SD = 2.20]), with 79.7% exceeding recommended guidelines (>1 h/day). After adjusting for confounders, screen time was associated with more socioemotional and behavioural difficulties among First Nations (total difficulties ß = 0.15 [95% CI, 0.12 to 0.19]) and Métis (ß = 0.16 [95% CI, 0.12 to 0.20]) but not Inuit children (ß = 0.12 [95% CI, 0.01 to 0.23]). CONCLUSIONS: Screen time exposure is high among Indigenous children in Canada, and is associated with more socioemotional and behavioural difficulties among First Nations and Métis children. Contributing factors could include enduring colonialism that resulted in family dissolution, lack of positive parental role models, and disproportionate socioeconomic disadvantage. Predictors of poor well-being should continue to be identified to develop targets for intervention to optimize the health and development of Indigenous children.

In-person 1-day cognitive behavioral therapy-based workshops for postpartum depression: a randomized controlled trial.

BACKGROUND: Postpartum depression (PPD) affects up to one in five mothers and birthing parents, yet as few as 10% access evidence-based treatment. One-day cognitive behavioral therapy (CBT)-based workshops for PPD have the potential to reach large numbers of sufferers and be integrated into stepped models of care. METHODS: This randomized controlled trial of 461 mothers and birthing parents in Ontario, Canada with Edinburgh Postnatal Depression Scale (EPDS) scores ⩾10, age ⩾18 years, and an infant <12 months of age compared the effects of a 1-day CBT-based workshop plus treatment as usual (TAU; i.e. care from any provider(s) they wished) to TAU alone at 12-weeks post-intervention on PPD, anxiety, the mother-infant relationship, offspring behavior, health-related quality of life, and cost-effectiveness. Data were collected via REDCap. RESULTS: Workshops led to meaningful reductions in EPDS scores (m = 15.77 to 11.22; b = -4.6, p < 0.01) and were associated with three times higher odds of a clinically significant decrease in PPD [odds ratio (OR) 3.00, 95% confidence interval (CI) 1.93-4.67]. Anxiety also decreased and participants had three times the odds of clinically significant improvement (OR 3.20, 95% CI 2.03-5.04). Participants reported improvements in mother-infant bonding, infant-focused rejection and anger, and effortful control in their toddlers. The workshop plus TAU achieved similar quality-adjusted life-years at lower costs than TAU alone. CONCLUSIONS: One-day CBT-based workshops for PPD can lead to improvements in depression, anxiety, and the mother-infant relationship and are cost-saving. This intervention could represent a perinatal-specific option that can treat larger numbers of individuals and be integrated into stepped care approaches at reasonable cost.

Associations between maternal postpartum depression and infant temperament in treatment-seeking mothers prior to and during the COVID-19 pandemic.

It remains unclear how the COVID-19 pandemic has affected the mother-infant relationship and associations between maternal postpartum depression (PPD) and offspring temperament. This study examined the impact of the pandemic on these links and how maternal ratings of the mother-infant relationship mediated associations between PPD and infant temperament in a sample of treatment-seeking mothers in Ontario, Canada before and during the COVID-19 pandemic. Mothers with infants <12 months of age and Edinburgh Postnatal Depression Scale scores ≥10 enrolled in two separate randomized controlled trials of 1-day cognitive behavioral therapy-based workshops for PPD conducted before COVID-19 (n = 392) and during the pandemic (n = 403). Mothers reported on depressive symptomatology, infant temperament, and the mother-infant relationship. Maternal PPD was associated with more infant negative affectivity and mother-infant relationship difficulties. While associations between PPD and infant-focused anxiety were stronger during COVID-19, the pandemic did not otherwise affect associations between PPD and infant temperament. Mediation analyses suggested that aspects of the mother-infant relationship mediated associations between PPD and infant negative affectivity. Findings highlight the importance of detecting PPD and intervening to potentially improve outcomes for mothers and their children.

Mental Health Challenges Among First Nations Adolescents Living Off-Reserve in Ontario, Canada.

Limited data exist on the mental health challenges facing First Nations adolescents and the factors that modify these difficulties. The current study compared levels of common mental health challenges among 112 off-reserve First Nations and 3334 non-First Nations adolescents (12-17 years old) and examined the impact of maternal psychological distress on these mental health challenges. First Nations adolescents self-reported higher symptoms of conduct, oppositional-defiant, attention-deficit hyperactivity, major depressive, social phobia, generalized anxiety, and separation anxiety disorders and all associations remained statistically significant after adjusting for covariates. Moderation analyses found that increasing levels of maternal distress were associated more strongly with symptoms of oppositional defiant, attention-deficit hyperactivity, major depressive, and generalized anxiety disorders in First Nations adolescents. Future work aimed at improving the mental health of First Nations youth that focus on supporting these adolescents, and their mothers in particular, could result in substantial benefits.

Public Health Nurse-delivered Group Cognitive Behavioural Therapy for Postpartum Depression: A Randomized Controlled Trial.

OBJECTIVES: To examine the effectiveness of group cognitive behavioural therapy (CBT) for postpartum depression (PPD) delivered by public health nurses with little to no previous psychiatric training at improving depression, worry, social support and the mother-infant relationship. METHODS: Mothers (n = 141) living in Ontario, Canada with Edinburgh Postnatal Depression Scale Scores ≥10 and an infant <12 months of age were randomized to receive nine weekly 2-h sessions of in-person group CBT for PPD delivered by two public health nurses plus treatment as usual (TAU; experimental group) or TAU alone (control group). Primary outcomes were change in EPDS score and current major depressive disorder (Mini International Neuropsychiatric Interview) assessed immediately post-treatment (T2). Secondary outcomes included maternal worry, social support, and quality of the mother-infant relationship. All outcomes were assessed again six months post-treatment (T3). RESULTS: Participants in the experimental group had statistically significantly greater reductions in PPD symptoms immediately post-treatment (T2) (B = -5.35, p < 0.01), were more likely to manifest a clinically significant improvement in EPDS scores (≥4 points; OR = 3.44, 95%CI: 1.49-7.94), and no longer have symptoms consistent with current MDD (OR = 5.31, 95% CI: 1.78-15.83). Six months post-treatment (T3), experimental group participants had higher odds of clinically significant PPD improvement (OR = 5.10, 95%CI: 1.89-13.78), while 25% of the experimental group and 70% of remaining control group participants reported current MDD (p < 0.01). Statistically significant improvements in worry and the mother-infant relationship were also observed, decreases maintained at six months post-treatment. CONCLUSIONS: Public health nurses with little to no previous psychiatric training can be trained to deliver effective group CBT for PPD to improve depression, worry, and the mother-infant relationship. Task shifting PPD treatment with group CBT to public health nurses could improve treatment uptake and lead to better outcomes for mothers, families, and the healthcare system.(Trial Registration NCT03039530).

Macrosomia and psychiatric risk in adolescence.

The prenatal environment can exert important effects on mental health. While much research has linked low birth weight to psychopathology, the intrauterine environment associated with high birth weight (macrosomia; > 4000 g) is also sub-optimal and may increase risk. Given the increasing prevalence of macrosomic births, understanding the mental health outcomes of infants born macrosomic can help refine theories of etiology, predict disorder, and target preventive interventions. Using data from the 2014 Ontario Child Health Study (OCHS), we examined the risk for psychiatric disorders in adolescents born macrosomic. Youth (N = 2151) aged 12-17 years completed the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). Rates of common mental disorders assessed by the MINI-KID were compared between those born at normal birth weight (NBW; 2500-4000 g, n = 1817) and adolescents born macrosomic (> 4000 g, n = 334). These associations were then adjusted for participant age, sex, socioeconomic status (SES) of the family, parental mental health, and gestational diabetes mellitus. After adjustment for covariates, adolescents born macrosomic had higher odds of conduct disorder (CD; OR = 3.19, 95% CI: 1.37-7.43), oppositional defiant disorder (ODD; OR = 1.79, 95% CI: 1.11-2.91), and ADHD (OR = 1.77, 95% CI: 1.21-2.80). Moderation analyses revealed that males born macrosomic were more likely to have psychiatric problems than their female peers. Socioeconomic disadvantage also amplified the risk posed by macrosomia for ODD, ADHD, major depressive disorder, and generalized anxiety disorder. In this study, macrosomia was associated with an increased risk of clinically significant externalizing problems in adolescence, most notably among boys and those facing socioeconomic disadvantage.

Online Public Health Nurse-Delivered Group Cognitive Behavioral Therapy for Postpartum Depression: A Randomized Controlled Trial During the COVID-19 Pandemic.

Objective: Rates of postpartum depression (PPD) increased during the COVID-19 pandemic, further highlighting the need for effective, accessible treatments for PPD. While public health nurses (PHNs) can be trained to help treat PPD, it is not known if they can effectively deliver evidence-based psychotherapies online to those with PPD.Methods: Mothers (n = 159) living in Ontario, Canada, with an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 10 and an infant < 12 months of age were randomized to receive a 9-week group cognitive behavioral therapy (CBT) intervention delivered by PHNs over Zoom, between October 2020 and November 2021. Experimental group participants received CBT plus treatment as usual (TAU), and control participants received TAU alone. Participants were assessed at baseline (T1), 9 weeks later (T2), and 6 months after T2 (T3). Primary outcomes were changes in EPDS score and current major depressive disorder (MDD) as measured by the Mini International Neuropsychiatric Interview. Secondary outcomes included worry, social support, the mother-infant relationship, and infant temperament.Results: At T2, experimental group participants showed clinically and statistically significant reductions on the EPDS (d = 0.65) and decreases in postpartum worry (d = 0.38) and rejection and pathological anger toward their infant (d = 0.44). They were also less likely to meet diagnostic criteria for current MDD compared to control participants (OR = 5.09; 95% CI, 1.18-21.98; number needed to treat [NNT: 3.7]). These improvements remained stable 6 months later (T3).Conclusions: PHNs can be trained to deliver effective online group CBT for PPD to reduce depression and worry and improve aspects of the mother-infant relationship, and they represent an important way to increase access to effective treatment for PPD.Trial Registration: ClinicalTrials.gov identifier: NCT04928742.

Depression, Anxiety, and Mother-Infant Bonding in Women Seeking Treatment for Postpartum Depression Before and During the COVID-19 Pandemic.

Objective: The conditions created by the COVID-19 pandemic could negatively affect maternal mental health and the mother-infant relationship. The aim of this study is to determine the impact of the COVID-19 pandemic on depression, anxiety, and mother-infant bonding among women seeking treatment for postpartum depression (PPD).Methods: Baseline data collected in two separate randomized controlled trials of a psychoeducational intervention for PPD in the same geographic region, one prior to COVID-19 (March 2019-March 2020) and one during the COVID-19 pandemic (April-October 2020), were compared. Eligible participants had an Edinburgh Postnatal Depression Scale (EPDS) score of ≥ 10, were ≥ 18 years of age, had an infant < 12 months old, and were fluent in English. Outcomes included PPD (EPDS), anxiety (Generalized Anxiety Disorder-7 [GAD-7]), and mother-infant relationship (Postpartum Bonding Questionnaire [PBQ]). All were measured continuously and dichotomized at accepted clinical cutoffs.Results: Of the 603 participants (305 pre-COVID-19; 298 during COVID-19), mothers enrolled during the COVID-19 pandemic reported higher levels of symptoms of PPD (B = 1.35; 95% CI, 0.64 to 2.06; Cohen d = 0.31) and anxiety (B = 1.52; 95% CI, 0.72 to 2.32; Cohen d = 0.30). During COVID-19, women had 65% higher odds of clinically significant levels of depression symptoms (OR = 1.65; 95% CI, 1.13 to 2.31) and 46% higher odds of clinically relevant anxiety symptoms (OR = 1.46; 95% CI, 1.05 to 2.05). However, there were no statistically significant differences in mother-infant bonding.Conclusions: The findings of this study suggest that rates and severity of PPD and anxiety symptoms among women seeking treatment for PPD have worsened in Canada during the COVID-19 pandemic. However, treatment-seeking mothers have consistently maintained good relationships with their infants. Considering the difficulties women with PPD face when accessing treatment, it is important that strategies are developed and disseminated to safely identify and manage PPD to mitigate potential long-term adverse consequences for mothers and their families.Trial Registration: ClinicalTrials.gov identifiers: NCT03654261 and NCT04485000.

Extremely low birth weight influences the relationship between stress and telomere length in adulthood.

This study examined the link between two biological markers of stress vulnerability at 22-26 years of age and telomere length at 30-35 among extremely low birth weight (ELBW; <1000 g) survivors and normal birth weight (NBW; >2500 g) control participants. Sixteen ELBW and 22 NBW participants provided baseline afternoon salivary cortisol samples and resting frontal electroencephalogram (EEG) alpha asymmetry data at 22-26 years. Buccal cells were assayed for telomere length at 30-35 years. Analyses controlled for sex, postnatal steroid exposure, childhood socioeconomic status, time of cortisol sample collection, and body mass index at 22-26 years. Salivary cortisol and frontal asymmetry at age 22-26 independently predicted telomere length at age 30-35, such that relatively higher cortisol and greater relative right frontal asymmetry at rest predicted telomere shortening among NBW controls, but not among ELBW survivors. However, similar associations were not noted in ELBW survivors, suggesting that ELBW survivors may have different mechanisms of stress coping as a result of their early-life exposures. These findings offer preliminary evidence in support of the role of stress in the genesis of cellular senescence at least among those born at NBW, but that these links may differ in those born preterm.

Maternal and Infant Performance on the Face-to-Face Still-Face Task following Maternal Cognitive Behavioral Therapy for Postpartum Depression.

OBJECTIVE: This study examined the impact of treating postpartum depression (PPD) with cognitive-behavioral therapy (CBT) on mother and infant behavior on the face-to-face still-face (FFSF) paradigm. METHODS: Data from 68 mothers and their infants, 35 women with PPD within 12 months of delivery, and 33 healthy control dyads matched on infant age, sex and familial socioeconomic status were examined. Women with PPD received nine weeks of group CBT and were compared with healthy control dyads with at three timepoints on changes in mother-infant performance on the FFSF. RESULTS: A significant group x FFSF phase x visit interaction was observed for infant withdrawn behavior at the three months post-treatment (p=0.006). Infants of mothers with PPD displayed significantly less withdrawn behavior after treatment, normalizing to levels of control infants. LIMITATIONS: A relatively small sample consisting predominantly of Caucasian mother-infant dyads and the presence of comorbid anxiety in the PPD group. CONCLUSION: Three months after group CBT for PPD, infants' withdrawn behavior appears to normalize to levels seen in the infants of healthy controls. Future studies should investigate whether treatments focused on the mother-infant dyad have distinctive effects on mothers and their infants' behaviors.

Extremely Low Birth Weight and Accelerated Biological Aging.

BACKGROUND AND OBJECTIVES: Extremely low birth weight (ELBW) (<1000 g) survivors are exposed to elevated levels of physiologic stress during their lives and may be susceptible to accelerated aging. Using the oldest known longitudinally followed cohort of ELBW survivors, we compared biological aging in this group using an epigenetic clock to a sample of matched normal birth weight (NBW) (>2500 g) control participants. METHODS: Buccal cells were collected from 45 ELBW survivors and 49 NBW control participants at 30 to 35 years of age. Epigenetic age was calculated from the weighted average of DNA methylation at 353 cytosine-phosphate-guanine sequence within DNA sites, by using the Illumina Infinium Human Methylation EPIC 850k BeadChip array. RESULTS: Before and after statistically adjusting for neurosensory impairment and the presence of chronic health conditions, a significant sex by birth weight group interaction was observed in the 353-site epigenetic-clock assay (P = .03), whereby ELBW men had a significantly older epigenetic age than NBW men (4.6 years; P = .01). Women born at ELBW were not found to be epigenetically older than their NBW peers. CONCLUSIONS: The results of this study suggest that prenatal exposures may play an important role in aging, and that men born preterm may experience accelerated aging relative to their peers. We further highlight the need to monitor and promote the health of preterm survivors, with a particular focus on healthy aging across the life span.

Effect of Online 1-Day Cognitive Behavioral Therapy-Based Workshops Plus Usual Care vs Usual Care Alone for Postpartum Depression: A Randomized Clinical Trial.

Importance: Postpartum depression (PPD) affects as many as 20% of mothers, yet just 1 in 10 of these women receives evidence-based treatment. The COVID-19 pandemic has increased PPD risk, reduced treatment access, and shifted preferences toward virtual care. Objective: To determine whether an online 1-day cognitive behavioral therapy (CBT)-based workshop added to treatment as usual improves PPD, anxiety, social support, mother-infant relationship quality, and infant temperament more than treatment as usual alone. Design, Setting, and Participants: This randomized clinical trial included 403 women with PPD who were recruited across Ontario, Canada, during the COVID-19 pandemic (April 20 to October 4, 2020). Women with Edinburgh Postnatal Depression Scale (EPDS) scores of at least 10 who were 18 years or older and had an infant younger than 12 months were eligible. Interventions: Women were randomly assigned to receive a live, interactive online 1-day CBT-based workshop delivered by a registered psychotherapist, psychiatrist, or clinical psychology graduate student in addition to treatment as usual (n = 202) or to receive treatment as usual and wait-listed to receive the workshop 12 weeks later (n = 201). Main Outcomes and Measures: The primary outcome was change in PPD (EPDS scores) in experimental and wait list control groups 12 weeks after baseline. Secondary outcomes included maternal anxiety (7-item Generalized Anxiety Disorder Questionnaire [GAD-7]), social support (Social Provisions Scale), quality of the mother-infant relationship (Postpartum Bonding Questionnaire), and infant temperament (Infant Behavior Questionnaire-Revised Very Short Form). Results: Participants all identified as women with a mean (SD) age of 31.8 (4.4) years. The workshop led to significant mean (SD) reductions in EPDS scores (from 16.47 [4.41] to 11.65 [4.83]; B = -4.82; P < .001) and was associated with a higher odds of exhibiting a clinically significant decrease in EPDS scores (odds ratio, 4.15; 95% CI, 2.66-6.46). The mean (SD) GAD-7 scores decreased from 12.41 (5.12) to 7.97 (5.54) after the workshop (B = -4.44; 95% CI, -5.47 to -3.38; P < .001) and participants were more likely to experience a clinically significant change (odds ratio, 3.09; 95% CI, 1.99-4.81). Mothers also reported improvements in bonding (B = -3.22; 95% CI, -4.72 to -1.71; P < .001), infant-focused anxiety (B = -1.64; 95% CI, -2.25 to 1.00; P < .001), social support (B = 3.31; 95% CI, 1.04 to 5.57; P < .001), and positive affectivity/surgency in infants (B = 0.31; 95% CI, 0.05 to 0.56; P < .001). Conclusions and Relevance: In this randomized clinical trial, an online 1-day CBT-based workshop for PPD provides an effective, brief option for mothers, reducing PPD and anxiety as well as improving social support, the mother-infant relationship, and positive affectivity/surgency in offspring. Trial Registration: ClinicalTrials.gov Identifier: NCT04485000.

The Mental Health of Young Canadian Mothers.

PURPOSE: Although many young mothers (aged <21 years) are exposed to multiple adversities that increase their risk for mental illness, prevalence data are largely limited self-report questionnaires estimating only the prevalence of postpartum depression. Gaining a greater understanding of the burden of a broader range of common mental illnesses affecting these young women has the potential to improve their health as well as the development and functioning of their children. METHODS: The Young Mothers Health Study recruited 450 mothers aged <21 years and 100 comparison mothers (aged >20 years old at first delivery) living in urban and rural central-west Ontario. Age-matched young mothers were also compared with 15- to 17-year-old women without children (N = 630) from the 2014 Ontario Child Health Study. The prevalence of current mental disorders was assessed using the Mini-International Neuropsychiatric Interview for Children and Adolescents. RESULTS: Nearly 2 of 3 young mothers reported at least one mental health problem, and almost 40% had more than one. Young mothers were 2 to 4 times as likely to have an anxiety disorder (generalized anxiety disorder, separation anxiety disorder, social phobia, and specific phobia), attention-deficit/hyperactivity disorder, oppositional defiant disorder, or conduct disorder and were 2 to 4 times more likely to have more than one psychiatric problem than older comparison mothers or women aged 15-17 years. CONCLUSIONS: Given the high rates of mental health problems and complex needs of young mothers in Canada and the possible adverse effects of maternal psychopathology on their children, further efforts should be directed at engaging and treating this high-risk group.
