"Social support and stressful life events: risk factors for antenatal depression in nulliparous and multiparous women".

Nulliparous (pregnant women who are giving birth for the first time) and multiparous (women who have multiple children) may have different concerns, which may be associated with risk of antenatal depression. This study aims to examine the role of social support and stressful life events as risk factors for antenatal depression in nulliparous and multiparous women. The sample included 1,524 pregnant women recruited from an obstetrics setting at the end of the first trimester of pregnancy from two Spanish tertiary-care public hospitals. The sample completed the Patient Health Questionnaire (PHQ-9), and the "social support" and "stressful life events" subscales of the Postpartum Depression Predictor Inventory-Revised (PDPI-R). Nulliparous women reported a lower prevalence of depressive symptoms (15.6 percent) compared to multiparous mothers (20.1 percent). In both groups, marriage/partner problems (NP: ß = 0.178, p < .01 vs MP: ß = 0.164, p < .01) and a perceived lack of instrumental support from friends (NP: ß = -0.154, p < .01 vs MP: ß = -0.154, p < .01) were significant risk factors for antenatal depression. However, nulliparous women have more risk factors such as unemployment (ß = 0.096, p < .05), job change (ß = 0.127, p < .01), financial problems (ß = 0.145, p < .01) and lack of instrumental support from partner (ß = -0187, p < .01). For multiparous women, moving (ß = 0.080, p < .05) and lack of instrumental support from family (ß = -0.151, p < .01) were risk factors. These results suggest the critical need for screening and designing preventive interventions adapted and taking into consideration parity to provide more effective health care during pregnancy.

Mothers' experiences of perinatal obsessive-compulsive disorder.

INTRODUCTION: Perinatal obsessive-compulsive disorder (POCD) is characterised by the presence of intrusive thoughts resulting in significant distress and urges to execute repeated behaviours occurring in the perinatal period. POCD is largely understudied and existing literature has mostly studied POCD quantitatively. OBJECTIVE: This qualitative study explores the experiences of 10 mothers randomly selected from a larger sample (N = 251; 86.8% White) who met high risk criteria based on the Postnatal Obsessive-Compulsive Scale (POCS≥16). These mothers were interviewed about their experiences with POCD retrospectively. RESULTS: Qualitative analysis of the interviews (n = 10) revealed three main themes regarding women's experiences with POCD: 1) obsessions (i.e. safety, cleanliness), 2) compulsions (i.e. excessive checking for safety, excessive cleaning, researching information online), and 3) other emotional experiences (i.e. fear, panic, anxiety, suicidal ideation, guilt, shame, irritability/anger). CONCLUSION: Mothers at high risk for POCD report obsessions and compulsions as well as other emotional experiences that are distressing, demonstrating the enduring impact of POCD beyond the perinatal period.

"The Mental Health Piece is Huge": perspectives on developing a prenatal maternal psychological intervention for congenital heart disease.

OBJECTIVES: Women carrying a fetus diagnosed with congenital heart disease often experience significant distress because of their medical diagnosis. Given the well-documented impact associated with elevated prenatal stress and critical importance of developing targeted interventions, this study aims to examine stressors, coping and resilience resources, and mental health treatment preferences in pregnant women receiving a congenital heart disease diagnosis to inform the development of a psychological intervention to reduce maternal distress prenatally. METHODS: Three groups of participants were included consisting of two pregnant women carrying a fetus with congenital heart disease, five women of children (4-16 months) with congenital heart disease, and five paediatric cardiology medical providers. Responses were gathered via semi-structured interviews and analysed using qualitative thematic analysis. RESULTS: Information regarding four broad areas were analysed of emotional distress during pregnancy; experience of initial diagnosis; coping and resilience; and perspectives on a mental health intervention in pregnancy. Anxiety regarding baby's future, guilt following diagnosis, and various coping strategies emerged as primary themes among the participant sample. Medical staff corroborated mothers' heightened anxiety and viewed a psychotherapeutic intervention during the prenatal period as essential and complimentary to standard of care. CONCLUSION: We identified salient themes and preferred components for a future psychological intervention delivered prenatally. PRACTICE IMPLICATIONS: Patients' and providers' perspectives regarding the nature of maternal distress, resilience and treatment preferences can inform the development of interventions to support the emotional well-being of pregnant women carrying a fetus with congenital heart disease to optimise care and potentially improve outcomes for fetal brain development.

Leading the charge toward a world without depression: perinatal depression can be prevented.

This manuscript is based on a keynote address presented at the 2020 Marcé Society's Conference celebrating the Society's 40th anniversary. The address described a 50-year perspective on prevention research, current evidence that perinatal depression can be prevented, and how digital tools could be used to disseminate perinatal depression prevention interventions throughout the world. We utilized the Mothers and Babies Course as a case study to illustrate these goals. The article reviews the gradual progress of depression prevention research, from the time when the state of the science was such that it was believed that the onset of major depressive episodes could not be prevented until the present day. In addition, the article recounts the three consensus reports on prevention of mental disorders published by the National Academies of Science, Engineering, and Medicine, culminating in the 2019 report, which calls on the field to implement known interventions for the prevention of depression and other mental disorders, and to scale up their administration to reduce the prevalence of these disorders in the general population. The paper presents the 2019 recommendations of the US Preventive Services Task Force, which instructs the health system to provide routine referrals to perinatal depression prevention interventions (e.g., the Mothers and Babies Course) to perinatal persons at risk for depression. We now have the knowledge to prevent approximately half of episodes of perinatal depression. It is time to implement this knowledge and begin to do research on how to prevent the remaining half.

A Systematic Review and Meta-Analysis of Risk Factors for Postpartum Depression Among Latinas.

OBJECTIVES: The purpose of this article was to describe the findings from a systematic review, quality review, and meta-analysis of risk factors for postpartum depression among adult Latinas in the United States. METHODS: Databases were searched from inception to May 2020 for studies published in English related to Latina/Hispanic mothers and risk factors of postpartum depression. Of 115 abstracts screened, 10 met the inclusion criteria for the review and meta-analysis. Eleven risk factors from these studies were included: acculturation, age, economic stress, education, marital status, number of children, prenatal depression, recent and remote intimate partner violence (IPV), general social support, and partner/father's social support. RESULTS: Partner/father's social support had a large effect size. Prenatal depression and recent IPV had medium effect sizes, while education, economic stress, general social support and remote IPV had small effect sizes. Negligible effect sizes were found for age, marital status, number of children, and acculturation. CONCLUSIONS: Prenatal depression, IPV, social support (general and from partner/father), economic stress and education are risk factors that should be screened for when working with perinatal Latinas. Future directions for clinical practice and research are discussed.

A Cross-Cultural Analysis of the Prevalence and Risk Factors for Prenatal Depression in Spain and Mexico.

The prevalence and risk factors associated with prenatal depression among Spanish-speaking women in Spain and Mexico are examined and compared through a cross-cultural study. The study utilizes secondary data from 563 participants who received prenatal care in Madrid (N = 283) and in Mexico City (N = 280), assessed with the PHQ-9 and the PDPI-R. Spanish women reported a lower prevalence of depressive symptoms (10.0%) than Mexican women (20.3%). Regression analyses showed that previous prenatal anxiety and lack of family emotional support were common risk factors to the two countries. Within each country, significant risk factors included: (a) previous depression history (ß = 0.224; p < 0.001) in Spain; and (b) unplanned pregnancy (ß = - 0.116; p < 0.027), lack of emotional support from others (ß = 0.129; p < 0.032), marital dissatisfaction (ß = 0.186; p < 0.009), and life stress due to financial problems (ß = 0.117; p < 0.026), and life stress due to marital problems (ß = 0.114; p < 0.040) in Mexico. Health professionals can tailor interventions to their particular risk factors to reduce the adverse effects on mothers and infants.

A mixed methods evaluation of an intervention to prevent perinatal depression among Latina immigrants.

Objective: The effectiveness of a cognitive behavioural intervention to prevent perinatal depression in low-income Latina immigrant pregnant women and mothers receiving WIC services was evaluated in a mixed methods study using a community based observational design.Background: The Mothers and Babies Course is a preventive intervention for perinatal depression that is based on cognitive behavioural theory (CBT). CBT is an evidence-based treatment and preventive intervention for perinatal depression.Method: Phase 1 includes 86 Latinas, predominantly Central American immigrant women at high risk for depression, who self-selected into the Mothers and Babies Course, a six-week Spanish CBT group intervention aimed at teaching women mood regulation skills to prevent the onset of depression. Participants, who were recruited from the Women, Infants, and Children services, completed measures of depression and psychopathology at pre-, 6 weeks, and 3 months post-intervention. Phase 2 includes qualitative interviews with a randomly selected subsample (n = 26) from Phase 1 to understand the mechanisms and impact of participants' experiences with the intervention and study.Results: Results indicated no significant differences in depressive symptoms among participants with varied attendance levels (0 class; 1-3 classes = non-completers; 4-6 classes = completers). None of the participants met diagnostic criteria for major depressive disorder at the final data collection period. Despite the varied attendance, both quantitative and qualitative results indicated that completers and non-completers reported similar experiences in the intervention and benefiting from study participation.Conclusion: Conducting mixed methods research highlights the complexity of understanding who can benefit from preventive interventions.

Latinx Mental Health Scholars' Experiences with Cultural Adaptation and Implementation of Systemic Family Interventions.

An increasing number of culturally adapted family-level interventions address mental health disparities with marginalized populations in the United States. However, with these developments many barriers have arisen, such as challenges with degree of cultural fit, engagement, and sustainability. We conducted 12 elite phenomenological interviews with mental health scholars involved in prevention and intervention family research with various Latinx communities within and outside of the United States. These scholars discussed their experiences of overcoming barriers in their research. We used thematic analysis to code and analyze participant responses, and our findings support the gaps in previous literature and highlight potential pathways to overcoming barriers in cultural adaptation research. Themes included the need for: (a) better understanding of the intersection between culture and context; (b) community-centered approaches to addressing implementation challenges; and (c) structural changes within institutional, governmental, and political levels. We discuss implications for researchers and practitioners working with Latinx families.

Un número cada vez mayor de intervenciones adaptadas culturalmente a nivel familiar abordan las desigualdades en la salud mental con poblaciones marginadas en los Estados Unidos. Sin embargo, con estos avances han surgido muchos obstáculos, como las dificultades con el grado de integración cultural, la participación y la sostenibilidad. Realizamos veinte entrevistas fenomenológicas selectas con investigadores de la salud mental dedicados a la investigación familiar en materia de prevención e intervenciones con varias comunidades latinas dentro y fuera de los Estados Unidos. Estos investigadores comentaron sus experiencias de superación de los obstáculos en su investigación. Utilizamos el análisis temático para decodificar y analizar las respuestas de los participantes; nuestros resultados respaldan la falta de datos en publicaciones previas y destacan las posibles vías para superar los obstáculos en la investigación sobre la adaptación cultural. Los temas incluyeron la nacesidad de: (a) una mejor comprensión del enlace entre la cultura y el contexto; (b) enfoques centrados en la comunidad para abordar las dificultades de implementación; y (c) cambios estructurales dentro de los niveles institucionales, gubernamentales y políticos. Debatimos las implicancias para los investigadores y los profesionales que trabajan con familias latinas.

Preventing perinatal depression in Spain: a pilot evaluation of Mamás y Bebés.

Objective: This pilot study evaluated the feasibility, acceptability, and preliminary effectiveness of a cognitive-behavioural intervention to prevent perinatal depressive symptoms in pregnant women at high risk for perinatal depression in Spain. Background: Perinatal depression (PD) can negatively affect maternal and infant outcomes. Mamás y Bebés/The Mothers and Babies Course (MBC) is an evidence-based CBT intervention aimed at teaching women at high risk for depression mood regulation skills to prevent depression in the United States, including Spanish-speaking perinatal women in the United States. However, there is limited research on preventive interventions for PD in Spain. Method: Pregnant women screened for high risk for PD were recruited in their first trimester in an obstetrics clinic at two urban hospitals in Spain. In a non-experimental design, 30 women completed eight weekly group sessions of the MBC. The Patient Health Questionnaire was the main depression outcome at four time points: pre-intervention, post-intervention, and at 3 months and 6 months postpartum. Participants completed an evaluation questionnaire at the end of each session to assess the acceptability of the intervention. Results: The MBC was effective in reducing depressive symptoms from baseline to all three time points: post-intervention, 3 and 6 months postpartum. Attendance was high (76.7% attended all eight sessions). Mothers reported positive feedback from the participating in the MBC. Conclusion: This pilot study suggests that the intervention is feasible, acceptable, and provides promising evidence for reducing depressive symptoms in urban Spanish perinatal women. Larger and rigorous randomised trials are needed to confirm these findings.

The Effectiveness of an App-Based Nurse-Moderated Program for New Mothers With Depression and Parenting Problems (eMums Plus): Pragmatic Randomized Controlled Trial.

BACKGROUND: Postnatal depression and caregiving difficulties adversely affect mothers, infants, and later childhood development. In many countries, resources to help mothers and infants are limited. Online group-based nurse-led interventions have the potential to help address this problem by providing large numbers of mothers with access to professional and peer support during the postnatal period. OBJECTIVE: This study tested the effectiveness of a 4-month online group-based nurse-led intervention delivered when infants were aged 2 to 6 months as compared with standard care outcomes. METHODS: The study was a block randomized control trial. Mothers were recruited at the time they were contacted for the postnatal health check offered to all mothers in South Australia. Those who agreed to participate were randomly assigned to the intervention or standard care. The overall response rate was 63.3% (133/210). Primary outcomes were the level of maternal depressive symptoms assessed with the Edinburgh Postnatal Depression Scale (EPDS) and quality of maternal caregiving assessed using the Parenting Stress Index (PSI; competence and attachment subscales), the Parenting Sense of Competence Scale (PSCS), and the Nursing Child Assessment Satellite Training Scale. Assessments were completed at baseline (mean child age 4.9 weeks [SD 1.4]) and again when infants were aged 8 and 12 months. RESULTS: Outcomes were evaluated using linear generalized estimating equations adjusting for postrandomization group differences in demographic characteristics and the outcome score at baseline. There were no significant differences in the intervention and standard care groups in scores on the PSI competence subscale (P=.69) nor in the PSCS (P=.11). Although the group by time interaction suggested there were differences over time between the EPDS and PSI attachment subscale scores in the intervention and standard care groups (P=.001 and P=.04, respectively), these arose largely because the intervention group had stable scores over time whereas the standard care group showed some improvements between baseline and 12 months. Mothers engaged well with the intervention with at least 60% (43/72) of mothers logging-in once per week during the first 11 weeks of the intervention. The majority of mothers also rated the intervention as helpful and user-friendly. CONCLUSIONS: Mothers reported that the intervention was helpful, and the app was described as easy to use. As such, it appears that support for mothers during the postnatal period, provided using mobile phone technology, has the potential to be an important addition to existing services. Possible explanations for the lack of differences in outcomes for the 2 groups in this study are the failure of many mothers to use key components of the intervention and residual differences between the intervention and standard care groups post randomization.

Adaptation of an evidence-based postpartum depression intervention: feasibility and acceptability of mothers and babies 1-on-1.

BACKGROUND: Mothers and Babies (MB) is a cognitive-behavioral intervention with demonstrated efficacy in reducing depressive symptoms and preventing depressive episodes among perinatal women when delivered in a group format by mental health professionals. Study aims were to describe the adaptation of MB into a 1-on-1 modality (MB 1-on-1) and provide data on the adapted intervention's acceptability and feasibility. METHODS: Seventy-five home visitors trained on MB 1-on-1 delivered the 15-session intervention to 1-2 clients. Client acceptability data assessed intervention enjoyment, comprehension, and usefulness. Home visitor feasibility and acceptability data measured amount of intervention material delivered, client comprehension, and client engagement. RESULTS: Home visitors were all female with 8.8 years of experience on average. 117 clients completed acceptability surveys. Average client age was 21.9 years and 41% were pregnant. Home visitors completely covered 87.9% of sessions and reported clients totally understood MB material 82.5% of the time across sessions, although variability was found in comprehension across modules. 82.0% of clients found MB 1-on-1 enjoyable and 91.6% said they totally understood sessions, when averaged across sessions. Clients enjoyed content on noticing one's mood and pleasant activities. Implementation challenges were client engagement, facilitating completion of personal projects, and difficulty shifting between didactic and interactive activities. CONCLUSIONS: Clients found MB 1-on-1 to be enjoyable, easily understood, and useful. Home visitors reported excellent implementation fidelity and felt clients understood MB material. A refined 12-session version of MB 1-on-1 should be examined for its effectiveness in reducing depressive symptoms, given encouraging feasibility and acceptability data.

A Pilot Study of Reduced Olfactory Bulb Volume as a Marker of PTSD in Childhood Trauma-Exposed Adult HIV-Infected Patients.

Evidence suggests that olfactory bulb (OB), a key structure in odor processing, may also be involved in mechanisms of traumatic stress. In animals, chronic stress reduces OB plasticity, and olfactory bulbectomy results in stress-enhanced startle reflex and autonomic dysregulation. However, OB morphometry has not been adequately studied in the development of stress disorders following childhood trauma in humans. The researchers conducted a pilot study evaluating the relationships between OB volume, childhood trauma, and lifetime posttraumatic stress disorder (PTSD) in a sample of 16 HIV-positive individuals, 13 of whom were exposed to childhood trauma of 9 developed PTSD. Participants were recruited from a larger cohort of inner city-dwelling HIV-positive populations in Washington, DC. Mean OB volumes were significantly reduced when PTSD and non-PTSD groups were compared, p = .019, as well as when trauma-exposed PTSD-positive and trauma-exposed PTSD-negative groups were compared, p = .008. No significant difference was observed when trauma-exposed and nonexposed participants were compared. The association between PTSD and right OB volume remained strong p = 0.002 after adjusting for group differences in sex, age, depression, hippocampal volume, and total intracranial volume. Because this study is limited by small sample size, further elucidation of relationships between OB, trauma, and PTSD should be investigated in larger cross-sectional and prospective studies and in diverse cohorts.

Preventing Perinatal Depression in High Risk Women: Moving the Mothers and Babies Course from Clinical Trials to Community Implementation.

A growing research literature highlights the public health need for preventive interventions to reduce symptoms and incidence of perinatal depression among vulnerable populations. The Mothers and Babies (MB) course is a cognitive-behavioral intervention designed to teach mood regulation skills to English- and Spanish-speaking low-income women at high risk for perinatal depression. We describe the development of the MB course and evaluate the extent to which research findings support efficacy, effectiveness, and dissemination based on the Society for Prevention Research Standards Committee's standards of evidence. Our review of research and implementation activities suggests that the MB intervention demonstrates promising evidence for efficacy in reducing depressive symptoms; empirical support for prevention of major depressive episodes is still preliminary. Work is in progress to evaluate program effectiveness and prepare for broad dissemination and implementation. The MB course shows promise as an intervention for low-income women at risk for perinatal mood issues. Spanish and English intervention materials have been developed that can be delivered in different settings (hospitals, home visiting), in different dosages (6, 8, or 12 sessions), and via different modalities (group, individual). Evaluating the MB course against current standards is intended to inform other prevention intervention development research.

The latent symptom structure of the Beck depression inventory: second edition in Latina pregnant women.

Pregnancy represents a unique period of time when women are at an increased risk of developing depression. Although the Beck Depression Inventory-Second Edition (BDI-II) is one of the most widely used self-report measures of depression symptomology, its psychometric properties and underlying factor structures have not been determined for antenatal women and among Latinas. The current study evaluated the latent symptom structure of the BDI-II in a community-based sample of Latina pregnant women (N = 217) identified to be at high risk for depression. Exploratory factor analyses were used to identify underlying salient individual item loadings for two- and three-factor models. Confirmatory factor analyses then examined several different indices to determine the best model fit. Examination of exploratory and confirmatory factor analyses supports a three-factor oblique structure of the BDI-II composed of Cognitive-Affective, Somatic, and Pregnancy Symptoms. The three-factor model provides clinicians with the ability to target specific constellations of depressive symptoms instead of relying on the BDI-II total score that represents the overall severity of depression in this population.

A systematic review of perinatal depression interventions for adolescent mothers.

Poor, adolescent, racial/ethnic minority women are at great risk for developing perinatal depression. However, little research has been conducted evaluating interventions for this population. We conducted a systematic review of preventive and treatment interventions for perinatal depression tested with adolescents, with a focus on low income, minority populations. Nine research-based articles (including one that reported on two studies) were reviewed systematically, and quality ratings were assigned based on a validated measure assessing randomization, double-blinding, and reporting of participant withdrawals. Two treatment studies were identified, both of which were successful in reducing depression. Eight prevention studies were located, of which four were more efficacious than control conditions in preventing depression. Studies sampled mostly minority, low socioeconomic status adolescents. No consistent characteristics across efficacious interventions could be identified. This review underscores the need for researchers to further investigate and build an evidence base.

"A Judgment-Free Zone": Adaptation and Pilot Study of a Virtual Wellness Group for African American Mothers with Young Children.

The COVID-19 pandemic has been particularly challenging for the mental health of African American (AA) birthing people. The pandemic necessitated shifting mental health care to online interventions. The goals of this study were to (1) describe an adapted evidence-based group preventive intervention for AA mothers with young children within a pediatric setting and (2) evaluate the feasibility, acceptability, and preliminary effectiveness of this virtual intervention. Phase 1 describes the adaptation of the HealthySteps Mom's Virtual Wellness Group, including eight weekly sessions based on the Mothers and Babies Course. Phase 2 was a mixed-methods, pre-post intervention design. Six AA mothers with young children completed questionnaires related to depression, anxiety, and parenting competence at three time points: pre-intervention (T1), post-intervention (T2), and 3 months post-intervention (T3). The participants also completed a focus group post-T2 to gather qualitative feedback regarding the intervention. The median scores for depression were lower at T2 and increased at T3, and for anxiety, they increased at T2 and decreased at T3. The median scores for parenting competence increased across the three time points. The participants attended a mean of 7.2 sessions (SD = 0.74). The qualitative results indicate that the participants gained a sense of empowerment, enjoyed connecting with other mothers, and acquired information. This pilot study suggests that a virtual intervention is feasible, acceptable, and can increase parenting competence and support among AA mothers with young children.

Time-resolved probes based on guanine/thymine-rich DNA-sensitized luminescence of terbium(III).

In this study, we have developed a novel strategy to highly sensitize the luminescence of terbium(III) (Tb(3+)) using a designed guanine/thymine-rich DNA (5'-[G3T]5-3') as an antenna ligand, in which [G3T]5 improved the luminescence of Tb(3+) by 3 orders of magnitude due to energy transfer from nucleic acids to Tb(3+) (i.e., antenna effect). Furthermore, label-free probes for the luminescent detection of biothiols, Ag(+), and sequence-specific DNA in an inexpensive, simple, and mix-and-read format are presented based on the [G3T]5-sensitized luminescence of Tb(3+) (GTSLT). The long luminescence lifetime of the probes readily enables time-resolved luminescence (TRL) experiments. Hg(2+) can efficiently quench the luminescence of Tb(3+) sensitized by [G3T]5 (Tb(3+)/[G3T]5); however, biothiols are readily applicable to selectively grab Hg(2+) for restoration of the luminescence of Tb(3+)/[G3T]5 initially quenched by Hg(2+), which can be used for "turn on" detection of biothiols. With the use of cytosine (C)-rich oligonucleotide c[G3T]5 complementary to [G3T]5, the formed [G3T]5/c[G3T]5 duplex cannot sensitize the luminescence of Tb(3+). However, in the presence of Ag(+), Ag(+) can combine the C base of c[G3T]5 to form C-Ag(+)-C complexes, leading to the split of the [G3T]5/c[G3T]5 duplex and then release of [G3T]5. The released [G3T]5 acts as an antenna ligand for sensitizing the luminescence of Tb(3+). Therefore, the Tb(3+)/[G3T]5/c[G3T]5 probe can be applied to detect Ag(+) in a "turn on" format. Moreover, recognition of target DNA via hybridization to a molecular beacon (MB)-like probe (MB-[G3T]5) can unfold the MB-[G3T]5 to release the [G3T]5 for sensitizing the luminescence of Tb(3+), producing a detectable signal directly proportional to the amount of target DNA of interest. This allows the development of a fascinating label-free MB probe for DNA sensing based on the luminescence of Tb(3+). Results and methods reported here suggest that a guanine/thymine-rich DNA-sensitized luminescence probe of Tb(3+) represents a new opportunity for versatile background-free biosensing applications.

In their own voices: Latinas' experiences with a randomized controlled trial.

We conducted exit interviews with a random sample of 39 predominantly Central American immigrant mothers who had completed a longitudinal randomized controlled trial to prevent perinatal depression. We found that rates and levels of perinatal depression in the intervention and control groups were lower than expected and did not differ between groups at 1 year postpartum. Therefore, we conducted extensive semistructured interviews to (a) understand why these high-risk women had such low rates of major depressive episodes and depressive symptoms, and (b) determine if the mechanisms responsible for reductions in depression differed between the intervention and usual care groups. We discovered that the intervention group learned specific mood-management skills from their participation in the intervention, and that the control group experienced their participation in the study as a "low-dose" intervention. Our experience highlights the importance of conducting qualitative studies to understand quantitative outcomes of intervention studies.

Effectiveness of interventions to prevent perinatal depression: An umbrella review of systematic reviews and meta-analysis.

BACKGROUND: To date, dozens of systematic reviews (SRs) and meta-analyses (MAs) summarize the effectiveness of preventive interventions for perinatal depression. However, the results are inconclusive, making an urgent need to step up to higher levels of evidence synthesis. AIMS: To summarize and compare the evidence from the SR&MA examining the effectiveness of all types of interventions for preventing perinatal depression. METHOD: PubMed, PsycINFO, Cochrane Database of Systematic Reviews and OpenGrey were searched from inception to December 2022. We selected SR&MA of randomized controlled trials (RCTs) that compared all types of preventive interventions for perinatal depression with control groups whose outcome was the reduction of depressive symptoms and/or incidence of new cases of perinatal depression (PROSPERO: CRD42020173125). RESULTS: A total of 19 SRs and MAs evaluated 152 unique RCTs that included 83,408 women from 26 countries and five continents. The median effect size for any intervention was SMD = 0.29 (95% CI: 0.20 to 0.38). Exercise/physical activity-based, psychological, and any type of intervention showed median effect sizes of 0.43, 0.28 and 0.36, respectively. The degree of overlap among RCTs was slight. According to AMSTAR-2, 79% of them were rated as low or critically low-quality. The strength of evidence, according to GRADE, was poorly reported and, in most cases, was low. CONCLUSIONS: Exercise/physical activity-based and psychological interventions have a small-to-medium effect on reducing perinatal depressive symptoms. There is insufficient evidence to conclude that dietary supplements and pharmacological interventions are effective in preventing perinatal depression. There is a need for high-quality SR&MA of RCTs, mainly focusing on universal preventive interventions.

The healthy moms and babies app to prevent postpartum depression: analysis of user-profiles and dropout cases.

Introduction: Perinatal depression affects mothers, babies and society. Preventive interventions are needed, but face barriers to access. E-health interventions could be an effective and accessible option. To date, few studies have attempted to understand the use of mobile health (m-health) applications and why they are not more widely used. This study aims to understand the demographic characteristics of enrolled participants and examine dropout patterns through the Healthy Moms and Babies app. Methods: A longitudinal study was conducted with a sample of 511 women recruited between 2020 and 2022. Data were collected from the app, including sociodemographic information, the participant's progress through the modules of the app, and the permissions granted to use the app. Results: Out of the 511 women who completed the initial form to initiate participation, 279 downloaded the app and completed the evaluation. Results indicated that granting permission to be notified about the module's availability is related to an increase in the use of the first modules. Conclusion: This study shows the importance of establishing follow-ups in the use of mobile apps during the perinatal period.
