Postpartum mood disorders and maternal perceptions of infant patterns in well-child follow-up visits

The association between tryptophan levels and postpartum mood disorders: a systematic review and meta-analysis

Over 50% of women experience mood disturbance in the postpartum period, with significant implications for maternal and infant health but identifying those at risk is not easily possible. The essential amino acid, tryptophan (TRP) through its neuroactive metabolites, has been implicated in the pathology of mood disorders. Thus, TRP levels tested in the peripartum period have been proposed as a potential biomarker for subsequent development of postpartum mood disturbances, in particular postpartum depression (PPD). A systematic review and meta-analysis following PROSPERO guidelines [CRD42021252462] was conducted on peer-reviewed, English language studies that measured blood levels of TRP during the postpartum period in women who were also evaluated for postpartum "blues" or PPD. Thirteen studies met the inclusion criteria, of which five studies contained sufficient data to conduct a meta-analysis. Low total TRP levels in postpartum days 1 to 5 were significantly associated with PPD (SMD: -5.39, 95%CI [-7.72, -3.05]). No significant association was found between free TRP levels in the postpartum period and PPD (SMD: -3.43, 95%CI [-7.76, 0.89]). Our findings confirm the necessity for more replicable designed studies regarding TRP and its relationship to postpartum depression. If there were greater clarity regarding TRP metabolism during pregnancy, then the next step would be to consider measuring total plasma TRP levels on postpartum days 1 to 5 to identify women at greater risk of developing PPD.

Perception of infant sleep problems: the role of negative affectivity and maternal depression

STUDY OBJECTIVES

To investigate whether the interaction between infant negative affectivity and maternal depressive symptoms is associated with the degree to which mothers perceive infant sleep to be problematic at 6 months postpartum, independent of infant sleep and sociodemographic factors.

METHODS

Infant negative affectivity and maternal depressive symptoms were assessed in a sample of 59 mother-infant dyads at 6 months postpartum using standardized measures. Mothers reported the degree to which they perceived their infant's sleep to be problematic via an item composite of the Sleep Practices Questionnaire. Nocturnal infant sleep variables (duration, number of awakenings) were retrieved from a 2-week infant sleep diary (maternal report).

RESULTS

There was a significant interaction between infant negative affectivity and maternal depressive symptoms in predicting mothers' perceived extent of infant sleep problems. Simple slope analysis showed that high levels of depression were related to higher maternal perception of infant sleep problem scores only among mothers of infants with high levels of negative affectivity. Moreover, infant negative affectivity and maternal depressive symptoms positively predicted perception scores after adjustment for infant sleep, maternal age, and parity (P < .05).

CONCLUSIONS

The current study provides evidence that high levels of maternal depression combined with high levels of infant negative affectivity may contribute to mothers' perceptions of infant sleep problems, independent of infant sleep duration and awakenings. These findings highlight the importance for pediatricians and other health professionals to consider infant temperament in conjunction with mothers' depressive symptoms when addressing mothers' concerns about infant sleep problems.

[The Role of Partnership Status and Relationship Satisfaction in Inpatient Mother-Child Treatment in Postpartum Mental Disorders]

The Role of Partnership Status and Relationship Satisfaction in Inpatient Mother-Child Treatment in Postpartum Mental Disorders The study examines the partnership status and satisfaction in connection with symptoms of postpartum mental disorders, mother-child attachment and outcome of inpatient mother-child treatment. Two sub-studies were carried out. In the first study, N = 126 mothers with postpartum mental disorders who went to a preliminary consultation for inpatient mother-child treatment stated their symptom burden (SCL-90), mother-child attachment (PBQ) and satisfaction with their partner relationship (PFB-K). Mothers with stressed relationships showed the highest level of symptom burden and impaired attachment. Mothers without a partner reported the least amount of impairment in mother-child attachment. In the second study, N = 41 mothers were examined over the course of inpatient treatment (within-subject design with a waiting-list). The initial relationship satisfaction was not predictive of symptom reduction or improvement in mother-child attachment. An increase in satisfaction during the treatment was though correlated with an improvement in mother-child attachment.

Consequences of maternal postpartum depression: A systematic review of maternal and infant outcomes

Introduction:

The postpartum period represents the time of risk for the emergence of maternal postpartum depression. There are no systematic reviews of the overall maternal outcomes of maternal postpartum depression. The aim of this study was to evaluate both the infant and the maternal consequences of untreated maternal postpartum depression.

Methods:

We searched for studies published between 1 January 2005 and 17 August 2016, using the following databases: MEDLINE via Ovid, PsycINFO, and the Cochrane Pregnancy and Childbirth Group trials registry.

Results:

A total of 122 studies (out of 3712 references retrieved from bibliographic databases) were included in this systematic review. The results of the studies were synthetized into three categories: (a) the maternal consequences of postpartum depression, including physical health, psychological health, relationship, and risky behaviors; (b) the infant consequences of postpartum depression, including anthropometry, physical health, sleep, and motor, cognitive, language, emotional, social, and behavioral development; and (c) mother–child interactions, including bonding, breastfeeding, and the maternal role.

Discussion:

The results suggest that postpartum depression creates an environment that is not conducive to the personal development of mothers or the optimal development of a child. It therefore seems important to detect and treat depression during the postnatal period as early as possible to avoid harmful consequences.

Using sertraline in postpartum and breastfeeding: balancing risks and benefits

INTRODUCTION

The World Health Organization recommends newborns to be breastfed but this may be challenging if the mother needs to be treated for depression, since strong evidence to inform treatment choice is missing.

AREAS COVERED

We provide a critical review of the literature to guide clinicians who are considering sertraline for the management of depression during postpartum.

EXPERT OPINION

Sertraline is one of the safest antidepressants during breastfeeding. In most cases, women already taking sertraline should be advised to breastfeed and continue the medication. We recommend to begin with low doses and to slowly increase the dose up, with careful monitoring of the newborn for adverse effects (irritability, poor feeding, or uneasy sleep, especially if the child was born premature or had low weight at birth). The target dose should be the lowest effective. When feasible, child exposure to the medication may be reduced by avoiding breastfeeding at the time when the antidepressant milk concentration is at its peak. A decision to switch to sertraline from ongoing and effective treatment should be taken only after a scrupulous evaluation of the potential risks and benefits of switching versus continuing the ongoing medication while monitoring the infant carefully.

Systematic review on maternal depression versus anxiety in relation to excessive infant crying: it is all about the timing

Different types of studies suggest a link between maternal depression/anxiety and excessive infant crying (EC). However, comparability is hampered due to different designs, definitions and measurements. This systematic review investigates the specific role of maternal depression and anxiety considering them as preceding, concurrent and subsequent conditions of EC. A computerised literature search was conducted in January 2017 using Medline, PubMed, PsycINFO and Web of Science. After screening n = 399 records for inclusion/exclusion criteria, n = 33 records based on n = 30 projects were eligible for systematic qualitative data synthesis. All studies on maternal depression/anxiety and EC within the first 3 years of life were included. Included studies investigated predominantly maternal depression (25/30) and secondly maternal anxiety (17/30). Significant positive results were found in the majority of studies for maternal depression (21/25) as well as for maternal anxiety (12/17) in relation to EC. In-depth analyses further revealed that concurrent and subsequent maternal depression was robustly related with EC, whilst preceding maternal depression was not. In contrast, preceding and concurrent (but not subsequent) maternal anxiety was consistently related to subsequent EC. Maternal depression is more likely a correlate or even a consequence of EC, whereas anxiety is rather a temporally preceding condition and thus a potential risk factor or risk marker for both subsequent EC and associated maternal depression. Interventions for EC should address concurrent maternal depression, whilst preventive approaches might target preceding maternal anxiety as early as prior to or during pregnancy.

Economic and Health Predictors of National Postpartum Depression Prevalence: A Systematic Review, Meta-analysis, and Meta-Regression of 291 Studies from 56 Countries

BACKGROUND

Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordingly, we conducted a meta-analysis to estimate the global and national prevalence of PPD and a meta-regression to identify economic, health, social, or policy factors associated with national PPD prevalence.

METHODS

We conducted a systematic review of all papers reporting PPD prevalence using the Edinburgh Postnatal Depression Scale. PPD prevalence and methods were extracted from each study. Random effects meta-analysis was used to estimate global and national PPD prevalence. To test for country level predictors, we drew on data from UNICEF, WHO, and the World Bank. Random effects meta-regression was used to test national predictors of PPD prevalence.

FINDINGS

291 studies of 296284 women from 56 countries were identified. The global pooled prevalence of PPD was 17.7% (95% confidence interval: 16.6-18.8%), with significant heterogeneity across nations (Q = 16,823, p = 0.000, I2 = 98%), ranging from 3% (2-5%) in Singapore to 38% (35-41%) in Chile. Nations with significantly higher rates of income inequality (R2 = 41%), maternal mortality (R2 = 19%), infant mortality (R2 = 16%), or women of childbearing age working ≥40 h a week (R2 = 31%) have higher rates of PPD. Together, these factors explain 73% of the national variation in PPD prevalence.

INTERPRETATION

The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal-child-health factors explain much of the national variation in PPD prevalence.

Magnitude and risk factors for postpartum symptoms: a literature review

BACKGROUND

The prevalence of postpartum depression worldwide varies from 0.5% to 60.8% in the first 12 months postpartum using self-reported questionnaire. This review aims to update the current magnitude of postpartum depression based on self-reported questionnaire and clinical interview and explore its associated factors in developed and developing countries.

METHODS

A literature search conducted between 2005 and 2014 identified 203 studies, of which 191 used self-reported questionnaire in 42 countries and 21 used structured clinical interview in 15 countries. Nine studies used a combination of self-reported questionnaire and clinical interview.

RESULT

The prevalence of postpartum depression varies from 1.9% to 82.1% in developing countries and from 5.2% to 74.0% in developed countries using self-reported questionnaire. Structured clinical interview shows a much lower prevalence range from 0.1% in Finland to 26.3% in India. Antenatal depression and anxiety, previous psychiatric illness, poor marital relationship, stressful life events, negative attitude towards pregnancy, and lack of social support are significant contributors to postpartum depression.

LIMITATION

All studies are included irrespective of the methodological quality, such as small sample size and their inclusion could affect the generalizability of the results.

CONCLUSION

The current prevalence of postpartum depression is much higher than that previously reported, and similar risk factors are documented. A culturally sensitive cut-off score with adequate psychometric properties of the screening instruments should be available. In future studies, examining the physical, biological, and cultural factors in qualitative studies and in those with adequate methodological qualities is recommended.

Postpartum depression screening in the pediatric emergency department

PURPOSE

This study aimed to determine the prevalence of and risk factors for postpartum depression (PPD) in mothers of young infants presenting to the pediatric emergency department (PED).

METHODS

This was a prospective, observational study to evaluate the prevalence of PPD in a sample of mothers of young infants presenting to the PED of an urban, tertiary care children's hospital. A convenience sample of mothers with infants younger than 4 months who presented to our urban, tertiary care PED was surveyed in English or Spanish using the Edinburgh Postpartum Depression Scale (EPDS). Demographic information was collected. Members of the study team evaluated and counseled those mothers who screened positive on the EPDS (score ≥ 10). During the PED visit, social work consultation and mental health resources were also offered. Resource use and additional mental health needs were assessed, with a follow-up telephone call 4 weeks after the initial ED presentation. Performance characteristics of a brief, 3-question anxiety subset were compared using a positive EPDS as the reference standard. All study participants were given information about community resources for new mothers. Data were analyzed using t test or Χ (with Yates correction as necessary).

RESULTS

A convenience sample of 200 mothers was enrolled; 31 (16%) of these mothers had an EPDS score of 10 or greater. Mothers had a mean age of 27 years (range, 15-41); 45% were first-time mothers; 40% got pediatric care in a state-funded clinic; and 10% were Spanish speaking. There were no statistically significant differences in baseline demographic characteristics of mothers with and without PPD. Mothers who were depressed were more likely to report that they either strongly agreed or agreed with the statement "I feel that my child is always fussy" (P = 0.004). The anxiety subscale produced a sensitivity of 0.87 (95% confidence interval [CI], 0.69-0.96), a specificity of 0.70 (95% CI, 0.63-0.77), and a negative predictive value of 0.97 (95% CI, 0.91-0.99). The majority of participants (92%) reached at follow-up reported improvement in their mood. Fifty percent reported discussing their mood with someone else, although only 33% of these women did so with a medical provider.

CONCLUSIONS

Postpartum depression affects a significant number of mothers of young infants who present to the PED for medical care. There are no clear demographic identifiers of these at-risk mothers, making universal screening an advisable approach. Capture of at-risk mothers during PED visits may accelerate connection with mental health resources. Anxiety seems to be a significant contributor. Mothers with PPD often characterize their infants to have a "fussy" temperament. The most appropriate referral for these women in this setting merits further investigation.

The process of developing and implementing a telephone-based peer support program for postpartum depression: evidence from two randomized controlled trials

BACKGROUND

A randomized controlled trial evaluated the effect of telephone-based peer support on preventing postpartum depression (PPD) among high-risk mothers. The results indicated that support provided by peer volunteers may be an effective preventative strategy. The purpose of this paper is to outline the process of developing, implementing, maintaining, and evaluating the peer support program that we used in this PPD prevention trial.

METHODS

The peer support program had been used successfully in a pilot trial and a previous breastfeeding peer support trial. Based on our experience and lessons learned, we developed a 4-phase, 12-step approach so that the peer support model could be copied and used by different health providers in various settings. We will use the PPD prevention trial to demonstrate the suggested steps.

RESULTS

The trial aim to prevent the onset of PPD was established. Peer volunteers who previously experienced and recovered from self-reported PPD were recruited and attended a four-hour training session. Volunteers were screened and those identified as appropriate to provide support to postpartum mothers were selected. Women who scored more than 9 on the Edinburgh Postnatal Depression Scale within the first two weeks after childbirth were recruited to participate in the trial and proactive, individualized, telephone-based peer support (mother-to-mother) was provided to those randomized to the intervention group. Peer volunteers maintained the intervention, supported other volunteers, and evaluated the telephone-based support program. Possible negative effects of the intervention were assessed. An in-depth assessment of maternal perspectives of the program at 12 weeks postpartum was performed.

CONCLUSIONS

The 4-phase, 12-step approach delineated in this paper provides clear and concise guidelines for health professionals to follow in creating and implementing community-based, peer-support interventions with the potential to prevent PPD.

Inconsolable infant crying and maternal postpartum depressive symptoms

OBJECTIVE

To quantify the extent to which maternal report of inconsolable infant crying, rather than colic (defined by Wessel's criteria of daily duration of fussing and crying >3 hours), is associated with maternal postpartum depressive symptoms.

METHODS

Participants were 587 mothers who were recruited shortly before or after delivery and followed longitudinally. At 5 to 6 weeks postpartum, mothers recorded the duration and mode (fussing, crying, or inconsolable crying) of their infant's distress by using the Baby's Day Diary. The Edinburgh Postnatal Depression Scale (EPDS) was administered at enrollment and at 8 weeks postpartum. Using regression models that included baseline EPDS scores and multiple confounders, we examined associations of colic and inconsolable crying with later maternal EPDS scores at 8 weeks postpartum.

RESULTS

Sixty mothers (10%) met the EPDS threshold for "possible depression" (score ≥9) at 8 weeks postpartum. For mothers reporting >20 minutes of inconsolable crying per day, the adjusted odds ratio for an EPDS score ≥9 was 4.0 (95% confidence interval: 2.0-8.1), whereas the adjusted odds ratio for possible depression in mothers whose infants had colic was 2.0 (95% confidence interval: 1.1-3.7). These associations persisted after adjusting for baseline depression symptoms.

CONCLUSIONS

Maternal report of inconsolable infant crying may have a stronger association with postpartum depressive symptoms than infant colic. Asking a mother about her ability to soothe her infant may be more relevant for potential intervention than questions about crying and fussing duration alone.

Increased mortality risk among offspring of mothers with postnatal depression: a nationwide population-based study in Taiwan

BACKGROUND

There is compelling evidence that children of mothers with postnatal depression (PD) experience poor developmental outcomes. However, no studies have specifically ascertained the risk of mortality for offspring during preschool years, the most catastrophic outcome in the vulnerable period. This nationwide population-based study aimed to investigate whether maternal depression in the first year after giving birth was associated with increased mortality risk among their preschool children aged up to 5 years.

METHOD

Three nationwide population-based datasets [the National Health Insurance Research Database (NHIRD), birth certificate registry and death certificate registry] were linked in this study. A total of 10 236 offspring of mothers with PD were recruited, together with a comparison cohort of 81 888 births matched with the affected women in terms of maternal age and year of delivery. Each child was traced for 5 years from delivery between 2001 and 2003 until the end of 2008 to determine mortality during preschool years.

RESULTS

During preschool years, 98 (0.96%) deaths were identified among the offspring of mothers with PD and 470 (0.57%) children in the comparison cohort died. For children up to 5 years old, exposure to maternal PD was independently associated with a 1.47-fold [95% confidence interval (CI) 1.16-1.87] increased mortality risk, after adjusting for family income, urbanization level and the characteristics of mother, father and infant. The risk of death by unnatural causes was even higher (about 2.23 times the risk, 95% CI 1.34-3.70) among exposed offspring.

CONCLUSIONS

PD places preschool children at significantly increased risk of mortality, especially from unnatural causes of death.

How can we identify vulnerable mothers who do not reach the cut off 12 points in EPDS?

The aim was to investigate the correspondence between 352 mother's self-reports about postpartum distress in a questionnaire including an item about distress 18 months after birth and their earlier scores within, on average, 2.5 months of childbirth from a screening with the Edinburgh Postnatal Depression Scale (EPDS). Mothers who did not reach the EPDS score of 12 points, but reported that they had been sad/depressed after childbirth, were similar in socio-demographic variables to mothers with no outcomes in sadness/depression issues. In items related to negative parenting and perceptions of the child, they presented the same picture as those with high EPDS scores who also reported having been depressed. These results suggest that EPDS does not identify all vulnerable mothers. Complementary methods for detecting mothers at risk of stress and depression need to be developed.

Postpartum depression

Postpartum depression (PPD) affects up to 15% of mothers. Recent research has identified several psychosocial and biologic risk factors for PPD. The negative short-term and long-term effects on child development are well-established. PPD is under recognized and under treated. The obstetrician and pediatrician can serve important roles in screening for and treating PPD. Treatment options include psychotherapy and antidepressant medication. Obstacles to compliance with treatment recommendations include access to psychotherapists and concerns of breastfeeding mothers about exposure of the infant to antidepressant medication. Further research is needed to examine systematically the short-term and long-term effect of medication exposure through breastmilk on infant and child development.
