Postnatal depression, anxiety and unsettled infant behaviour

The unsettled baby: crying out for an integrated, multidisciplinary primary care approach

Unsettled behaviour in the first few months of life is a common clinical problem, with the associated risks of postnatal depression, premature cessation of breastfeeding, long-term psychological disturbance, and child abuse. Parents of new babies complain of difficulty accessing appropriate care and receiving conflicting advice. Although organic disturbance is implicated in only 5% of cases, gastro-oesophageal reflux disease, food allergies and lactose intolerance are often mistakenly diagnosed in unsettled babies. There is no evidence that acid-suppressive medications help in treating unsettled behaviour and, until the hypothesis that proton-pump inhibitors may predispose to food allergies has been properly investigated, treatment with acid-suppressive medications should be avoided in this population. Although unsettled behaviour in infants is commonly a transient neurodevelopmental phenomenon that peaks at 6 weeks of age, failure to diagnose other correctable problems, including breastfeeding difficulty and cows milk allergy, risks entrenching anxiety and disrupted mother-infant interactions in the long term. In the current climate of health system reform, the design and evaluation of an integrated, evidence-based, multidisciplinary primary care approach to management of unsettled babies and their mothers is a priority.

Development of a universal psycho-educational intervention to prevent common postpartum mental disorders in primiparous women: a multiple method approach

BACKGROUND

Prevention of postnatal mental disorders in women is an important component of comprehensive health service delivery because of the substantial potential benefits for population health. However, diverse approaches to prevention of postnatal depression have had limited success, possibly because anxiety and adjustment disorders are also problematic, mental health problems are multifactorially determined, and because relationships amongst psychosocial risk factors are complex and difficult to modify. The aim of this paper is to describe the development of a novel psycho-educational intervention to prevent postnatal mental disorders in mothers of firstborn infants.

METHODS

Data from a variety of sources were synthesised: a literature review summarised epidemiological evidence about neglected modifiable risk factors; clinical research evidence identified successful psychosocial treatments for postnatal mental health problems; consultations with clinicians, health professionals, policy makers and consumers informed the proposed program and psychological and health promotion theories underpinned the proposed mechanisms of effect. The intervention was pilot-tested with small groups of mothers and fathers and their first newborn infants.

RESULTS

What Were We Thinking! is a psycho-educational intervention, designed for universal implementation, that addresses heightened learning needs of parents of first newborns. It re-conceptualises mental health problems in mothers of infants as reflecting unmet needs for adaptations in the intimate partner relationship after the birth of a baby, and skills to promote settled infant behaviour. It addresses these two risk factors in half-day seminars, facilitated by trained maternal and child health nurses using non-psychiatric language, in groups of up to five couples and their four-week old infants in primary care. It is designed to promote confidence and reduce mental disorders by providing skills in sustainable sleep and settling strategies, and the re-negotiation of the unpaid household workload in non-confrontational ways. Materials include a Facilitators' Handbook, creatively designed worksheets for use in seminars, and a book for couples to take home for reference. A website provides an alternative means of access to the intervention.

CONCLUSIONS

What Were We Thinking! is a postnatal mental health intervention which has the potential to contribute to psychologically-informed routine primary postnatal health care and prevent common mental disorders in women.

Maternal sleep and depressive symptoms: links with infant Negative Affectivity

This study assessed whether elevated severities of maternal depression and disturbed maternal sleep would be associated with maternal perceptions of higher Negative Affectivity of her infant. Sixty-nine mothers participated in this study. The study was part of a larger randomized controlled study testing the efficacy of acupuncture as a treatment for depression during pregnancy. The present study focused on data collected at 6 months postpartum in a naturalistic follow-up design, using the Hamilton Rating Scale for Depression (HRSD), maternal sleep diaries (completed daily for 1 week), and the Infant Behavior Questionnaire-Revised (IBQ-R). Regression analyses revealed that (a) maternal depression severity was a significant predictor of the IBQ-R Distress and Falling Reactivity scales and (b) poor maternal sleep was a significant predictor of the IBQ-R Sadness scale. Our findings support previous findings of significant links between maternal emotional distress and perceived Negative Affectivity of her infant's temperament and provide a novel insight linking maternal poor sleep with perceived sadness of the infant.

Maternal distress: a concept analysis

AIM

This paper is a report of an analysis of the concept of maternal distress.

BACKGROUND

Although not well-developed, the concept of maternal distress has offered an important viewpoint in nursing and midwifery practice since the mid-1990s. Traditionally, understanding of maternal distress has been based on the medical model and dysfunction. The concept of maternal distress needs development so that it describes responses ranging from normal stress responses to those indicating mental health problem/s.

DATA SOURCES

The SCOPUS, CINAHL and Medline databases were searched for the period from 1995 to 2009 using the keywords 'psychological distress', 'emotional distress' and 'maternal distress'.

REVIEW METHODS

Steps from Rodgers' evolutionary concept analysis guided the conduct of this concept analysis.

RESULTS

Four attributes of maternal distress were identified as responses to the transition to motherhood, with the level of each response occurring along a continuum: stress, adapting, functioning and control, and connecting. Antecedents to maternal distress include becoming a mother, role changes, body changes and functioning, increased demands and challenges, losses and gains, birth experiences, and changes to relationships and social context. The consequences of maternal distress are compromised mental health status, maternal role development, quality of life, ability to function, quality of relationships and social engagement. The extent of the impact depends on the level of maternal distress.

CONCLUSION

Clearer interpretation of maternal distress offers a comprehensive approach to understanding maternal emotional health during the transition to motherhood. Acknowledging women's experiences and providing more appropriate support could alleviate some of the struggles and hardships experienced by mothers.

The contribution of Australian residential early parenting centres to comprehensive mental health care for mothers of infants: evidence from a prospective study

BACKGROUND

Australia's public access residential early parenting services provide programs to assist parents who self-refer, to care for their infants and young children. Treatment programs target infant feeding and sleeping difficulties and maternal mental health. There is limited systematic evidence of maternal and infant mental health, psychosocial circumstances or presenting problems, or the effectiveness of the programs. The aim of this study was to contribute to the evidence base about residential early parenting services.

METHODS

A prospective cohort design was used. A consecutive sample of mothers with infants under one year old recruited during admission to a public access residential early parenting service for a 4 or 5 night stay in Melbourne, Australia was recruited. They completed structured self-report questionnaires, incorporating standardised measures of infant behaviour and maternal mood, during admission and at one and six months after discharge. Changes in infant behaviour and maternal psychological functioning after discharge were observed.

RESULTS

79 women completed the first questionnaire during admission, and 58 provided complete data. Women admitted to the residential program have poor physical and mental health, limited family support, and infants with substantial behaviour difficulties. One month after discharge significant improvements in infant behaviour and maternal psychological functioning were observed (mean (SD) daily crying and fussing during admission = 101.02 (100.8) minutes reduced to 37.7 (55.2) at one month post discharge, p < 0.001; mean (SD) Edinburgh Postnatal Depression Scale at admission = 11.3 (5.7) reduced to 6.78 (4.44), at one month, p < 0.001) which were sustained at six months. Participant satisfaction with the program was high; 58 (88%) found the support of the nurses and 50 (75%) the social support of other mothers very helpful.

CONCLUSIONS

This psycho-educational approach is an effective and acceptable early intervention for parenting difficulties and maternal mood disturbance, and contributes to a system of comprehensive mental health care for mothers of infants.

Maternal psychopathology and outcomes of a residential mother-infant intervention for unsettled infant behaviour

OBJECTIVE

Residential mother-infant intervention programmes for unsettled infant behaviour have been shown to be associated with positive child and maternal outcomes. Despite evidence of elevated rates of maternal psychopathology among residential unit populations, little is known about whether psychological disorders interfere with the effectiveness of such interventions.

METHOD

Two cohorts (n = 104 and 147, respectively) were recruited from a residential mother-infant intervention programme for unsettled infant behaviour. In study 1, mothers completed self-report questionnaires measuring depression, anxiety and parenting stress at three time points (admission, 1 month after discharge and 3 months after discharge). In study 2, mothers were interviewed using a structured clinical interview for depressive and anxiety disorders. In both studies, nurses recorded infant behaviours over the duration of the 5 day admission using 24 h behaviour charts.

RESULTS

Study 1 showed the intervention to be associated with significant improvements in child behaviours and in levels of maternal depression, anxiety and parenting stress. These improvements were evident for women who scored above the Edinburgh Postnatal Depression Scale threshold for major depression during the admission, as well as for women in the normal range. Study 2 confirmed that the intervention was associated with significant improvements in infant behaviours. Infants of mothers with a depressive or anxiety disorder were less unsettled on admission, but improvements over the course of the admission were comparable for infants of women who had, or had not, experienced an anxiety or depressive disorder during the admission.

CONCLUSIONS

These results show positive infant and maternal outcomes associated with a residential mother-infant intervention for unsettled infant behaviour, regardless of the women's psychiatric status on admission. This suggests that women with depression or anxiety disorders who also report unsettled infant behaviour, will benefit from referral to residential programmes.

A systematic review of the effects of postnatal maternal anxiety on children

Several decades of research have focused on the impact of exposure to postnatal depression on children, while anxiety has been largely overlooked. Estimates of the prevalence of postnatal maternal anxiety (PMA) range from 3% to 43%, suggesting PMA may be an important risk factor for adverse outcomes in children. This review summarizes what is known about the effects of PMA exposure on children and makes recommendations for future research. A systematic search of Ovid MEDLINE and PsychINFO through 2008 identified 18 studies that evaluated child outcomes associated with PMA exposure. Identified studies covered three domains: somatic, developmental, and psychological outcomes. The strongest evidence for an adverse effect of PMA exposure is in somatic and psychological outcomes; the evidence for an effect of PMA on child development is inconclusive. Methodological differences among the studies make comparisons difficult and there are a number of common limitations that challenge the validity of these studies.

Treating infant sleep disturbance: does maternal mood impact upon effectiveness?

AIM

To explore whether mild-to-moderate maternal depression affects the effectiveness of a behavioural approach to treating infant sleep disturbance (ISD).

METHODS

The health records of 90 mothers attending an inpatient parenting service for management of their 5-12-month-old infant's sleep difficulties were examined. These records contained detailed, nurse-completed, 24-hour behaviour charts of infant sleeping and crying. Participants were allocated to the depression group based on Edinburgh Depression Scale score and/or review of mental health assessment notes.

RESULTS

There were no differences between infants of mothers with (n= 39) or without (n= 51) depression on either (i) the severity of their initial sleeping difficulty, or (ii) their response to behavioural treatment. Both groups showed significant improvements over the 5-day stay on all sleep variables observed, including number of night wakings, time to fall asleep, time spent crying at night and total time slept at night.

CONCLUSIONS

Mild-to-moderate maternal depression does not appear to attenuate ISD behavioural treatment outcomes. Given ISD treatment has been shown to improve maternal mood, the results of this study argue against recommendations initially to address maternal mood in isolation when managing ISD.

The impact of postnatal and concurrent maternal depression on child behaviour during the early school years

BACKGROUND

This prospective study explores the ongoing impact of early and subsequent maternal depression on offspring behaviour in the early school years.

METHODS

Seventy five mothers recruited into a longitudinal study were assessed for symptoms of depression when their children were 4, 12 and 15 months, 4 years and later when the children were 6-8 years of age. Mothers, fathers, and school teachers were asked to report on children's internalising and externalising behaviour problems.

RESULTS

Exposure to maternal depression during the first postpartum year was related to mother reports of child internalising and externalising problems in the early school years. Although depression in the first year predicted later internalising problems, effects for externalising behaviour problems were mediated by concurrent depression. Relations between concurrent maternal depression and externalising problems were confirmed by teacher ratings. Interestingly, the severity of symptoms at four months was significantly correlated with behaviour problems seven years later.

LIMITATIONS

Attrition over successive study contacts and therefore limited statistical power is acknowledged. Findings may be a conservative estimate of associations between maternal depression and later child behaviour problems. Also, the high prevalence of depressive symptomatology in the population from which the sample was drawn may limit the generalisability of results.

CONCLUSIONS

Findings confirm the importance of early identification and treatment for mothers with postnatal depression, given the likelihood of ongoing depression and relations with later child behaviour problems. From a practical point, severity of early symptoms may be a reliable index of those mothers and children at greatest risk.

Fragmented maternal sleep is more strongly correlated with depressive symptoms than infant temperament at three months postpartum

To determine the contribution of infant temperament to the relationship between maternal sleep disturbance and depressive symptoms. Utilizing a repeated measures design, 112 couples recruited from childbirth education classes were assessed in third trimester and postpartum. Instruments included Center for Epidemiologic Studies Depression Scale, General Sleep Disturbance Scale, wrist actigraphy, and an investigator-developed tool to assess infant temperament completed by mothers and fathers. Regardless of infant temperament, mothers who slept < 4 h between midnight and 6 am and mothers who napped < 60 min during the day were at increased risk for depression at three months postpartum. Infant temperament was associated with maternal sleep but was not a significant predictor of depressive symptoms after controlling for other contextual factors. Postpartum clinical visits should include questions about maternal sleep so interventions can be directed toward sufficient sleep to minimize risk of postpartum depression.

Screening for maternal depression in the neonatal ICU

Postpartum depression is common in women with infants in the neonatal ICU. Maternal depression can affect infant health and development adversely. A screening program for depression in the neonatal ICU could identify women who have depressive symptoms and facilitate their referral for follow-up services.

Posttraumatic stress symptoms following childbirth and mothers' perceptions of their infants

Postpartum psychological distress can adversely affect the early mother-infant relationship; however, this has not been investigated in relation to posttraumatic stress disorder (PTSD) following childbirth. This article explores whether PTSD symptoms relating to labor and delivery are associated with mothers' early perceptions of their infant. Using labor and childbirth as the stressor criterion, 211 women were assessed at 6 weeks' postpartum for symptoms of intrusions, avoidance, and hyperarousal. Their perceptions of their infants, of mother-to-infant attachment, and infant behavioral characteristics also were evaluated. In sum, 3.8% of the women fulfilled full diagnostic criteria, and a further 21.3% reported clinically significant symptoms on at least one dimension of PTSD. Those meeting full or partial criteria perceived their attachment relationships to be significantly less optimal and reported more negative maternal representations in terms of their infants being less warm and more invasive. They also rated them as being temperamentally more difficult, prone to distress, and less easy to soothe. However, when the effects of depression were partialled, only the effect for perceived warmth remained. Posttraumatic stress symptoms relating to labor and delivery may adversely influence maternal perceptions of infants, with potentially adverse implications for the developing mother-infant relationship. The overlap with depressive symptoms requires further exploration.

Maternal state of mind regarding attachment predicts persistence of postnatal depression in the preschool years

BACKGROUND

This prospective study aimed to determine predictors of persistent postnatal depression between child age one and four years, in a sample of mothers already identified as having a high incidence of postnatal depression at four months after birth and a relatively high prevalence of symptoms of depression at child age one year.

METHODS

Data (self-report questionnaires and interview) were initially collected from 127 mothers of first-born infants recruited from a parent-craft hospital at four months postpartum. Women again completed questionnaires and interviews one year after the birth. Persistence of depression between one and four years was assessed by symptom checklists and diagnostic interview.

RESULTS

Ninety-two mothers (72%) of the original sample participated at four years. Eleven women who had first onset of depression after one year were excluded from analyses. Thirty-eight percent of the remaining sample (56% of those diagnosed with depression at 4 months) reported ongoing depression between one and four years. Severity of depressive symptoms at four months and maternal state of mind regarding attachment (assessed at 1 year) were significant predictors of persistent depression. Women with an insecure state of mind regarding attachment at one year were seven times more likely to report ongoing depression.

CONCLUSIONS

Findings confirm that postnatal depression is ongoing for many women and that vulnerability to persistent depression needs to be viewed in the context of inter-generational family problems. Severity of symptoms at four months postpartum can be used to identify those mothers most at risk of persistent depression.

Rates of depressive and anxiety disorders in a residential mother-infant unit for unsettled infants

OBJECTIVE

Depression and anxiety are known to be common among women presenting to residential mother-infant programmes for unsettled infant behaviour but most studies have used self-report measures of psychological symptomatology rather than diagnostic interviews to determine psychiatric diagnoses. The aim of the present study was to determine rates of depressive and anxiety disorders and rates of comorbidity among clients of the Karitane residential mother-infant programme for unsettled infant behaviour.

METHOD

one hundred and sixty seven [corrected] women with infants aged 2 weeks-12 months completed the Edinburgh Postnatal Depression Scale and were interviewed for current and lifetime history of depressive and anxiety disorders using the Structured Clinical Interview for DSM-IV diagnosis (Research version).

RESULTS

A total of 25.1% of the sample met criteria for a current diagnosis of major depression, 31.7% had met criteria for major depression since the start of the pregnancy, and 30.5% of clients met criteria for a current anxiety disorder. Of note were the 21.6% who met criteria for generalized anxiety disorder or anxiety disorder not otherwise specified (worry confined to the topics of the baby or being a mother). High levels of comorbidity were confirmed in the finding that 60.8% of those with an anxiety disorder had experienced major or minor depression since the start of their pregnancy and 46.3% of those who had experienced depression since the start of their pregnancy also met criteria for a current anxiety disorder.

CONCLUSIONS

There are high levels of psychiatric morbidity among clients attending residential mother-infant units for unsettled infant behaviour, highlighting the importance of providing multifaceted interventions in order to address both infant and maternal psychological issues.

Maternal depression and infant temperament characteristics

One hundred-thirty-nine women participated in this longitudinal study from the third trimester of pregnancy through 8-months postpartum. Women completed depression scales at several time points and rated their infant's characteristics and childcare stress at 2- and 6-months postpartum. Mothers' reports of infant temperament were significantly different for depressed and non-depressed mothers, with depressed mothers reporting more difficult infants at both measurement points. These differences remained after controlling for histories of maternal abuse or prenatal anxiety, which occurred more often in the depressed mothers. There were no significant differences in childcare stress or perceived support between the groups. Infant temperament and childcare stress did not change over time. Recommendations for practice include consistent ongoing evaluations of the "goodness of fit" within the dyad and exploring interventions for depressed mothers that provide guidance about interactions with their infants and the appropriateness of the infant behaviors.

Maternal anxiety in the pre- and postnatal period: a literature review

This study intended to present a systematic review to analyze the empirical studies published between 1998 and 2003 about maternal anxiety in the prenatal and postnatal periods, focusing on pre-term and term births. Nineteen studies were found; six of which evaluated maternal anxiety in the prenatal period, 12 studies evaluated anxiety in mothers in the postnatal period and only one study evaluated maternal anxiety in both periods. The results showed that high levels of maternal anxiety in the prenatal phase were associated with obstetric problems, emotional damages to fetal development, behavioral problems in childhood and adolescence. The mothers presented higher anxiety levels when compared with the fathers. The co-occurrence of maternal anxiety and depression was found. The maternal anxiety assessment is relevant to identify both maternal mental health and child development at risk.

Management of neonatal abstinence syndrome in neonates born to opioid maintained women

Neonates born to opioid-maintained mothers are at risk of developing neonatal abstinence syndrome (NAS), which often requires pharmacological treatment. This study examined the effect of opioid maintenance treatment on the incidence and timing of NAS, and compared two different NAS treatments (phenobarbital versus morphine hydrochloride). Fifty-three neonates born to opioid-maintained mothers were included in this study. The mothers received methadone (n=22), slow-release oral morphine (n=17) or buprenorphine (n=14) throughout pregnancy. Irrespective of maintenance treatment, all neonates showed APGAR scores comparable to infants of non-opioid dependent mothers. No difference was found between the three maintenance groups regarding neonatal weight, length or head circumference. Sixty percent (n=32) of neonates required treatment for NAS [68% in the methadone-maintained group (n=15), 82% in the morphine-maintained group (n=14), and 21% in the buprenorphine-maintained group (n=3)]. The mean duration from birth to requirement of NAS treatment was 33 h for the morphine-maintained group, 34 h for the buprenorphine-maintained group and 58 h for the methadone-maintained group. In neonates requiring NAS treatment, those receiving morphine required a significantly shorter mean duration of treatment (9.9 days) versus those treated with phenobarbital (17.7 days). Results suggest that morphine hydrochloride is preferable for neonates suffering NAS due to opioid withdrawal.

Postnatal psychiatric morbidity: a validation study of the GHQ-12 and the EPDS as screening tools

OBJECTIVE

To assess the validity of the 12-Item General Health Questionnaire (GHQ-12) and the Edinburgh Postnatal Depression Scale (EPDS) in screening for the most common postnatal psychiatric morbidities (mood, anxiety and adjustment disorders).

METHOD

A two-phase cross-sectional study was designed. First, a sample of 1453 women visiting at 6 weeks postpartum completed the GHQ-12 and the EPDS questionnaires. Second, based upon EPDS outcomes, participants were stratified and randomly selected within each stratum for clinical evaluation [Structured Clinical Interview for DSM-IV (SCID)]. Receiver operating characteristic (ROC) analysis was used.

RESULTS

The concurrent validity was satisfactory (0.80). At optimum cut-off scores, both GHQ-12 and EPDS yielded very good sensitivity (80; 85.5) and specificity (80.4; 85.3), respectively. ROC curves showed that the performance of the EPDS (AUC=0.933) is slightly superior to that of GHQ-12 (AUC=0.904).

CONCLUSION

Both GHQ-12 and EPDS are valid instruments to detect postnatal depression as well as postnatal anxiety and adjustment disorders.

Fish consumption in pregnancy and omega-3 status after birth are not associated with postnatal depression

BACKGROUND

Research to date suggests a relationship between fish consumption, omega-3 polyunsaturated fatty acids, and depression. However, interpretation of this research is difficult due to methodological limitations. Postpartum women provide an excellent opportunity to examine these relationships because omega-3s are transferred from mother to fetus during pregnancy and from mother to child after birth through breast milk. Hence new mothers are more likely to be depleted in omega-3s. Our aim was to determine whether prenatal fish consumption and omega-3 status after birth were associated with postnatal depression.

METHODS

Eighty first-time mothers were recruited; 41 who scored on or over the cut-off on one of two depression-screening instruments, and 39 in the control group. Depression was diagnosed using the Composite International Diagnostic Interview. Fish consumption was measured during pregnancy, and depression and omega-3 status were determined postnatally. Logistic regression and t-tests were used to examine relationships between fish consumption, omega-3 status, and postnatal depression, while controlling for known covariates.

RESULTS

Prenatal fish consumption was not predictive of postnatal depression, and postnatal omega-3 status was not associated with postnatal depression. However, prenatal fish consumption did predict omega-3 status after birth.

LIMITATIONS

Prenatal fish consumption was measured using only a food frequency questionnaire, and no participants consumed oily fish (rich in omega-3s) regularly.

CONCLUSIONS

There was no association between postnatal depression and either fish consumption in early pregnancy, or omega-3 status after birth. Our findings make it difficult to justify trials of omega-3 polyunsaturated fatty acids in the treatment of postnatal depression.

Mental health issues within the general health care system: the challenge for nursing education in Australia

The mental health content of undergraduate nursing programs has consistently been identified as inadequate in preparing graduate nurses with the knowledge and skills for, and interest in, a career in mental health nursing. Since the introduction of generic nursing education, undergraduate programs have become primarily focused on the development of generalist skills, with specialisation occurring at postgraduate level. The integration of mental health services within the broader health care system in Australia has led to a significant increase in the prevalence of mental health problems within the general health care setting. The relevant literature suggests that nurses are not well prepared to meet the mental health care needs of this population. The aim of this paper is to briefly outline the incidence of mental health problems within the general health care system, the implications for nursing, and the potential role which nursing could play in recognising, and providing appropriate care for the treatment of mental health problems. The implications for nursing education, and the need for mental health nursing skills to be considered essential for all nurses will be discussed.

Maternal trait anxiety, depression and life event stress in pregnancy: relationships with infant temperament

AIMS

To assess whether links exist between maternal trait anxiety (STAI), perceived life event (LE) stress and depression (Edinburgh scale) and infant temperament.

STUDY DESIGN AND SUBJECTS

Women in the third trimester of pregnancy returned psychological self-report questionnaires; infant temperament was evaluated at 4 and 6 months by maternal and paternal report, while depression (concurrent Edinburgh scale) was also assessed at four and six months. As data were returned inconsistently at 4 and 6 months, we combined these two time points for simplicity of reporting and optimisation of numbers.

RESULTS

Univariate logistic regressions on 970 subjects indicated that the pregnancy STAI (>40) scores were associated with 2.56- and 1.57-fold increases (maternal and paternal, respectively), in the odds of "difficult" infant temperament at 4 or 6 months. Concurrent Edinburgh scores (OR of 3.06 and 2.64 for maternal reports, respectively) were also predictive of infant temperament. Age, education, income, marital status, obstetric complications, infant gender and prematurity were not predictive of infant temperament. In stepwise multiple logistic regression analyses, the antenatal trait STAI (odds ratio 1.96) significantly predicted maternal reports of "difficult" temperament at 4 or 6 months independent of both antenatal and postnatal depression scores. There were similar trends for paternal reports of "difficult" temperament but these were not significant. Antenatal depression and perceived LE stress were not predictive of temperament. Finally, women (N=14) reporting domestic violence (DV) in pregnancy had highly significant increased Edinburgh and STAI scores.

CONCLUSIONS

Maternal trait anxiety was predictive of "difficult" infant temperament, independent of "concurrent" depression and key sociodemographic and obstetric risk factors. These findings, while needing replication using objective measures of infant temperament, suggest that antenatal psychological interventions aimed at minimising anxiety may optimize infant temperament outcomes. There may be some benefit in shaping specific interventions to women reporting specific risk factors such as DV or past abuse.

1. Problem crying in infancy

Up to 20% of parents report a problem with infant crying or irritability in the first 3 months of life. Crying usually peaks at 6 weeks and abates by 12-16 weeks. For most irritable infants, there is no underlying medical cause. In a minority, the cause is cow's milk and other food allergy. Only if frequent vomiting (about five times a day) occurs is gastro-oesophageal reflux a likely cause. It is important to assess the mother-infant relationship and maternal fatigue, anxiety and depression. Management of excessive crying includes: explaining babies' normal crying and sleeping patterns; helping parents help their baby deal with discomfort and distress through a baby-centred approach; helping parents recognise when their baby is tired and apply a consistent approach to settling their baby; encouraging parents to accept help from friends and family, and to simplify household tasks. If they are unable to manage their baby's crying, admission to a parenting centre (day stay or overnight stay) or local hospital should be arranged.

Mental illness in women who have young children: current literature

Postnatal depression is an illness that has been researched a great deal in recent years. While much is known about the prevalence and contributing factors, it is not clear whether antenatal interventions are successful in preventing postnatal depression. Mother-child relationships where the mother has a mental illness, have been reported to be more negative and may adversely affect the child's development. Many researchers discuss the importance of supporting such families, not only to improve their current situation, but also to help prevent the development of mental health problems in the children.

Etiology and treatment of postpartum depression

This article reviews the risk factors, pathogenesis, treatment, and prevention of postpartum depression. Postpartum depression is common and occurs in up to 18% of newly delivered mothers. Though the hormonal changes occurring after childbirth are believed to play a role in postpartum depression, no hormonal etiology has been identified. Estrogen appears somewhat helpful for postpartum depression, but its use is limited by problematic medical sequelae. Several antidepressants are effective for postpartum depression and appear safe for use by breastfeeding women. Psychosocial interventions and cultural rituals, which may prevent or ameliorate postpartum depression, have also been employed.
