Does postnatal depression screening work? Throwing out the bathwater, keeping the baby

Emotional health screening of mothers, preliminary validation of a 3-item instrument: A research brief

A number of countries now recommend population-wide depression screening for perinatal women, using validated tools. A stepped-approach to screening - involving universal screening with a brief measure, followed by targeted screening using a longer measure for those women identified as at greater risk - is used in some settings. This brief report describes the test performance characteristics of a 3-item mood screening instrument, developed for use within a digital parenting program. Participants (n = 404) in this cross-sectional study were mothers of children aged up to 3 years. The majority (65.5 %) were first-time mothers, and their mean age was 32.8 years. Data were collected using an online survey. The test performance of the brief 3-item mood screening instrument (possible score range = 0-300) was examined using Receiver Operating Characteristic (ROC) analysis, with a score of 13 or more on the Edinburgh Postnatal Depression Scale (EPDS) used as the reference standard. The mood screening instrument demonstrated excellent range when compared to the reference standard. Optimal balance between sensitivity (0.77) and specificity (0.78), was achieved at a cut-point of 160 or less. Analysis was limited by using only the EPDS as the reference standard. This preliminary data supports the use of this 3-item mood screening instrument to screen for postnatal depression symptoms and may be integrated into a mobile Health or online tool. Future research should examine the test performance of the 3-item mood screening instrument against a diagnostic tool.

The Association between Late Third-Trimester Oxytocin Level and Early-Onset Postpartum Depression Symptoms among Jordanian Mothers: A Cross-sectional Study

PURPOSE

Oxytocin has been suggested to play a vital role in modulating maternal behavior and stress-related disorders. However, the relationship between antenatal oxytocin and postpartum depression is not well established. We aim to investigate the association between serum oxytocin level in the late third-trimester and early-onset postpartum depression symptoms.

MATERIALS AND METHODS

A total of 172 healthy pregnant women participated in this cross-sectional descriptive study. The serum oxytocin level was measured between 34 and 37 weeks. A validated Edinburgh Postnatal Depression Scale (EPDS) was used to assess symptoms of depression four to six weeks postpartum. Participants who scored more than 12 on the EPDS were considered having depressive symptoms. Independent sample t-test and Pearson r were used to examine differences in depression scores. The level of significance was set at α = 0.05.

RESULTS

30.8% of the participants experienced depressive symptoms. There was no association between EPDS scores and oxytocin level r(170) = 0.10, p = 0.23. The association also did not exist even among women with a lifetime history of depression r(43) = -0.13, p = 0.37. Participants with low education, low income, previous history of depression, positive family history of depression, positive family issues, and absent emotional family support have scored significantly higher on EPDS scores than their counterparts. The strongest association was with previous lifetime history of depression t(170) = -4.40, p < 0.001.

CONCLUSIONS

Postpartum depression is a major public health problem in Jordan. Late trimester serum oxytocin level has no association with early-onset postpartum depression.

Validated screening tools to identify common mental disorders in perinatal and postpartum women in India: a systematic review and meta-analysis

BACKGROUND

Perinatal common mental disorders are associated with significant adverse outcomes for women and their families, particularly in low- and middle-income settings. Early detection through screening with locally-validated tools can improve outcomes.

METHODS

We searched MEDLINE, Embase, PsycINFO, Global Health, Cochrane Library, Web of Science and Google Scholar for articles on the validation of screening tools for common mental disorders in perinatal women in India, with no language or date restrictions. Quality was assessed using the QUADAS-2 tool. We used bivariate and hierarchical summary receiver operating characteristic models to calculate pooled summary estimates of sensitivity and specificity. Heterogeneity was assessed by visualising the distance of individual studies from the summary curve.

RESULTS

Seven studies involving 1003 women were analysed. All studies assessed the validity of the Edinburgh Postnatal Depression Scale (EPDS) in identifying perinatal depression. No validation studies of any other screening tools were identified. Using a common threshold of ≥13 the EPDS had a pooled sensitivity and specificity of 88·9% (95%CI 77·4-94·9) and 93·4 (95%CI 81·5-97·8), respectively. Using optimal thresholds (range ≥ 9 to ≥13) the EPDS had a pooled sensitivity and specificity of 94·4% (95%CI 81·7-98·4) and 90·8 (95%CI 83·7-95·0), respectively.

CONCLUSION

The EPDS is psychometrically valid in diverse Indian settings and its use in routine maternity care could improve detection of perinatal depression. Further research is required to validate screening tools for other perinatal common mental disorders in India.

Maternal depression and the emotional availability of mothers at six months postpartum: Findings from the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS) pregnancy cohort

BACKGROUND

Existing research suggests maternal depression may reduce the quality of early mother-infant interaction and this might increase our understanding of how maternal mental health impacts on child development outcomes. However, most studies recruit from community samples and few include both a diagnostic measure of maternal depression together with an observational measure of the quality of the mother-infant relationship.

METHODS

Data was drawn from 210 women recruited in early pregnancy until 6 months postpartum within an Australian pregnancy cohort, the Mercy Pregnancy and Emotional Wellbeing Study. Those women who at six months postpartum were video recorded interacting with their infant for at least 40-minutes were included in this study, with the quality of those interactions assessed using the Emotional Availability Scales coding system. Depression was measured using the Structured Clinical Interview for the DSM-IV-TR Clinician Version and the Edinburgh Postnatal Depression Scale, and covariates included maternal age and education.

RESULTS

Whilst results showed a small negative association between antenatal depressive symptoms in trimester one of pregnancy and maternal EA, there was no effect of maternal depression diagnosis or of maternal depressive symptoms in later pregnancy or postpartum.

LIMITATIONS

This study focuses exclusively on mothers and does not account for the role of partners.

CONCLUSIONS

Maternal depression might have a smaller effect on maternal EA then some existing research implies, with that effect most prevalent in early pregnancy. Clinical intervention might not be necessary for all mother-infant dyads experiencing depressive symptomology, but instead be directed to those with additional risk factors.

Exercise frequency and maternal mental health: Parallel process modelling across the perinatal period in an Australian pregnancy cohort

OBJECTIVE

Since the potential mental health benefits of exercise during pregnancy remain unclear, this study examined longitudinally the bidirectional relationship between exercise and maternal mental health symptoms during the perinatal period, and included adjustment for both depression and antidepressant treatment.

METHODS

Data were collected across pregnancy (first and third trimesters) and the postpartum (six and 12 months) for 258 women drawn from an Australian pregnancy cohort, the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS). The women were assessed for depression using the EPDS, anxiety using the STAI and a clinical diagnostic interview (SCID-IV), and self-reported use of antidepressants. Exercise was measured using self-reported weekly frequency of 30-min bouts of moderate to vigorous exercise, and data were analyzed using parallel process growth curve modelling.

RESULTS

On average, women's weekly exercise frequency declined during pregnancy, returning to first trimester levels by 12 months postpartum. Women with depression and taking antidepressants reported lower first trimester exercise compared to control women. However, where non-medicated depressed women remained lower and continued to decline to 12 months, women taking antidepressants reported increasing levels of exercise during the perinatal period. Notably, a steeper decline in exercise frequency during the perinatal period was associated with a faster rate of increase in depressive and anxiety symptoms.

CONCLUSIONS

This study is the first to examine the longitudinal interaction between exercise and mental health symptoms across the perinatal period. These preliminary findings demonstrate potential benefits for depressive and anxious symptoms when maintaining levels of early-pregnancy exercise throughout pregnancy and the postpartum.

A comparison of the PHQ-2 and MGMQ for screening for emotional health difficulties during pregnancy

BACKGROUND

Routine screening for emotional health difficulties in women during pregnancy is now advocated in several countries. There is a need therefore to compare the performance of different self-report measures to accomplish this. This study reports on the comparative performance of two such measures- the well-established PHQ-2, which aims to detect depression, and the more recent MGMQ, which aims to detect a wide array of negative emotions.

METHOD

Women (N = 2292) attending a public hospital antenatal clinic over a 14-month period completed the two measures, either on their own (72%), verbally administered by the midwife (25%), or with an interpreter (3%).

RESULTS

Similar rates of women screened positive on each instrument (PHQ-2: 11.6%; MGMQ: 12.3%), but the overlap between the two measures was low. The PHQ-2 only detected 58% of the MGMQ screen positive women, while the MGMQ detected 89.5% of the PHQ-2 screen positive women. No clinically meaningful difference in screen positive rates on either measure was evident for the administration method.

LIMITATIONS

No demographic data were available apart from gestational age, and only about half the women presenting to the clinic during the time period were screened with the measures.

CONCLUSION

The MGMQ detected a greater proportion of women screening positive on the PHQ-2 than vice-versa. This is part due to the MGMQ's focus on a wider range of negative emotions than just depression. Accumulating evidence for this MGMQ indicates that clinical services can consider using this simple measure if they wish to screen for a broad range of negative emotions during pregnancy and postnatally.

Screening for and Treating Postpartum Depression and Psychosis: A Cost-Effectiveness Analysis

Objectives Postpartum depression impacts 6.5-12.9% of U.S. women. Postpartum depression is associated with impaired bonding and development, marital discord, suicide, and infanticide. However, the current standard of care is to not screen women for postpartum depression. This study modeled the cost-effectiveness of physicians screening for and treating postpartum depression and psychosis in partnership with a psychiatrist. Methods This study follows a hypothetical cohort of 1000 pregnant women experiencing one live birth over a 2-year time horizon. We used a decision tree model to obtain the outcomes of screening for and treating postpartum depression and psychosis using the Edinburgh Postnatal Depression Scale. We use a Medicaid payer perspective because they cover approximately 50% of births in the U.S. The cost-effectiveness of the intervention is measured in cost per remission achieved and cost per quality-adjusted life-year (QALY) gained. We conducted both deterministic and probabilistic sensitivity analyses. Results Screening for and treating postpartum depression and psychosis produced 29 more healthy women at a cost of $943 per woman. The incremental cost-effectiveness ratios of the intervention branch compared to usual care were $13,857 per QALY gained (below the commonly accepted willingness to pay threshold of $50,000/QALY gained) and $10,182 per remission achieved. These results were robust in both the deterministic and probabilistic sensitivity analyses of input parameters. Conclusions for Practice Screening for and treating postpartum depression is a cost-effective intervention and should be considered as part of usual postnatal care, which aligns with the recently proposed recommendations from the U.S. Preventive Services Task Force.

A double-blind, randomized, placebo-controlled trial of saffron stigma (Crocus sativus L.) in mothers suffering from mild-to-moderate postpartum depression

INTRODUCTION

Numerous adverse effects of antidepressants as well as the attitudes of breastfeeding mothers, who prefer to consume herbal medicine rather than chemical drugs, encouraged us to assess the effects of saffron (Crocus sativus L.) on mothers suffering from mild-to-moderate postpartum depressive disorder.

METHODS

A double-blind, randomized, and placebo-controlled trial was conducted on 60 new mothers who had a maximum score of 29 on the Beck Depression Inventory-Second Edition (BDI-II). They were randomly assigned to the saffron (15 mg/Bid) or placebo group. The primary outcome was a change in the BDI-II scores 8 weeks after treatment compared to the baseline. The response and remission rates were considered to be secondary outcome measures.

RESULTS

Saffron had a more significant impact on the BDI-II scores than the placebo. The mean BDI-II scores decreased from 20.3 ± 5.7 to 8.4 ± 3.7 for the saffron group (p < .0001) and from 19.8 ± 3.2 to 15.1 ± 5.4 for the placebo group (p < .01). In the final assessment, 96% of the saffron group were in remission compared to 43% of the placebo group (p < .01). The complete response rates were 6% for the placebo group and 66% for the saffron group.

CONCLUSION

When administered to treat minor PPD in breastfeeding mothers, saffron had a more significant impact on the BDI-II than the placebo.

Using the Edinburgh Postnatal Depression Scale for women and men-some cautionary thoughts

The objective of the study was to critically consider some of the possible limitations in the Edinburgh Depression Scale (EDS), given that great emphasis is put on the results of this measure within both clinical and research fields. Using findings and discussion points from other studies, as well as from a critical analysis of issues by the authors based upon their clinical and research experience, possible limitations with the scale in nine areas are discussed. Possible limitations include the following: (1) ambiguous items, (2) exclusion of certain types of distress, (3) scoring difficulties, (4) low positive predictive value, (5) frequent use of incorrect cut-off scores, (6) a vast array of validated cut-off scores, (7) validation against a questionable gold-standard, (8) limited anxiety detection and of depressive symptoms in men, and (9) many screen positive women only have transient distress. While the EDS has unquestionably been an extremely valuable instrument in aiding in the recognition of the importance of perinatal mental health, users of the scale should be aware that it, like other measures, has limitations. We discuss possible strategies to overcome these limitations and describe a recent scale that has been developed to surmount these shortcomings more effectively.

Postpartum depression symptoms among Amazonian and Northeast Brazilian women

BACKGROUND

Studies analyzing the prevalence of postpartum depression in Brazil have recently increased. However, few studies have examined the Northeast region of Brazil, and no studies have investigated the Amazon region. Therefore, the aim of this study was to investigate postpartum depression in these two regions.

METHODS

We administered the Edinburgh Postnatal Depression Scale to a total of 3060 women who used the Brazilian public health system and had given birth between one and three months prior to the interview. A cut-off score ≥11 was used to indicate symptoms of postpartum depression. After calculating the prevalence, univariate logistic regressions were performed separately for several possible risk factors (p<0.05).

RESULTS

The overall rate of reported symptoms of postpartum depression was 19.5%. The prevalence in the northeast region and Amazon region were 19.0% and 20.3%, respectively (p=0.36). In the univariate logistic regression, low education level (<7 years: p<0.001; 8-10 years: p=0.003), ethnicity (Black: p=0.02; Pardo: p=0.02), few prenatal visits (1 or 2 visits: p=0.04), prenatal care self-assessed as "not very good" (p<0.001) and the prenatal care adequacy index of partially suitable (p=0.01) or not suitable (p<0.001) were identified as significant risk factors for postpartum depression symptoms.

LIMITATIONS

Mothers who did not bring their children for immunization. The cross-sectional study does not allow for causality to be established.

CONCLUSION

the prevalence rates of postpartum depression were similar to the rates observed for developing countries and higher than the rates observed in developed countries. Based on these findings, we recommend that screening and treatment of pregnant women should be considered a public health priority.

Postpartum Depression Screening: A Review for Psychiatrists

LEARNING OBJECTIVES

After participating in this activity, learners should be better able to:• Evaluate the rationale for screening women for postpartum depression• Assess tools for screening for postpartum depression

OBJECTIVE

To perform a qualitative literature review on screening for postpartum depression (PPD), as applicable to the general psychiatrist. Results are classified by instrument, timing, and clinical setting of the screen.

DATA SOURCES

A literature search was conducted using the PubMed database for English-language articles published since January 1987. Of the 2406 citations initially identified, 61 articles remained after application of inclusion and exclusion criteria.

RESULTS

Among numerous screening tools for PPD, the Edinburgh Postnatal Depression Scale is the most widely used. Data suggest that screening for PPD should commence soon after delivery, with subsequent screens at multiple time-points in the postpartum period. Primary care, pediatric, and obstetric settings are all viable locations for screening, but are ineffective without follow-up mental health evaluations. Less data are available to define optimal patterns either for screening in psychiatric settings or for the psychiatrist's role in managing perinatal depression.

CONCLUSIONS

The American Congress of Obstetricians and Gynecologists, American Academy of Pediatrics, and most authors firmly recommend screening for PPD. The Edinburgh Postnatal Depression Scale can be administered in various clinical settings. Screening should occur at multiple time-points throughout the first postpartum year. The psychiatrist's role in early detection and prevention of PPD requires further exploration.

Routine antenatal maternal screening for current mental health: evaluation of a change in the use of the Edinburgh Depression Scale in clinical practice

A hospital antenatal clinic conducting routine psychosocial screening changed the Edinburgh Depression Scale (EDS) referral criterion for determining which women needed to be referred to a multidisciplinary meeting health professional ("Safe Start meeting"). The criterion was changed from a score of 10 or more to 13 or more, when no other psychosocial risks were present. Women scoring 10-12 on the EDS, with no other psychosocial risks, were now informed they should contact the Social Work Department if they had issues they wanted to discuss with a health professional. The study evaluated the impact of this change in EDS clinical practice. Records were audited over a 20-month period. In addition, 20 women scoring in this EDS marginal range (10-12), with no other psychosocial risks, participated in a telephone interview to ascertain if they should have been referred to the Safe Start meeting. Of 174 eligible women who scored in the marginal EDS range, none had contacted the Social Work Department. In addition, none of the 20 women interviewed indicated that they would have wanted to talk further with a health professional. This change in clinical practice reduced monthly referrals to the Safe Start meeting by about 20%. There was a linear relationship between the increasing EDS category scores and the likelihood of psychosocial risks being endorsed. Increasing the automatic referral EDS cutoff score from 10 or more to 13 or more does not appear to result in women "in need" being missed. The reduction in referrals allowed more time in the Safe Start meeting to be devoted to women with greater needs.

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.

Routine depression screening in an MS clinic and its association with provider treatment recommendations and related treatment outcome

Depression, a frequent concomitant disorder in multiple sclerosis (MS), can impact MS treatment adherence and quality of life. Depression screening in MS care settings may facilitate needed intervention when providers are responsive to screening findings. This study sought to examine the relationship between depression screening results and provider depression treatment recommendations documented in the medical records of 283 patients receiving care in an integrated MS clinic. Forty-six percent of patients screening positive for depression received a treatment recommendation; females, those with past mental health diagnoses, on psychotropic medications, and those with higher symptom severity were more likely to receive a treatment recommendation. On subsequent screenings, patients reported fewer depressive symptoms regardless of whether a formal treatment recommendation was documented. These findings suggest that while depression screening does lead to depression related intervention in many cases, more research is necessary to determine who is most likely to benefit and under what conditions.

Perinatal depression: an update and overview

Over the last 3 years there have been notable developments in the screening and treatment of perinatal depression. Most importantly, the DSM-V has made only minor changes in the diagnostic criteria for perinatal depression as compared to the DSM-IV; "perinatal," as opposed to "postpartum," is a specifier for depression with a requirement that the depression onset occurs during pregnancy or the first 4 weeks postpartum. Advances in the treatment of perinatal depression have been made over the last 3 years, including both prevention and acute interventions. Additional support has emerged confirming the primary risk factors for perinatal depression: a personal or family history, low SES and poor interpersonal support. There is general agreement that universal screening be conducted for all perinatal women, by both the woman's obstetrician and the baby's pediatrician.

Explaining ecological clusters of maternal depression in South Western Sydney

BACKGROUND

The aim of the qualitative study reported here was to: 1) explain the observed clustering of postnatal depressive symptoms in South Western Sydney; and 2) identify group-level mechanisms that would add to our understanding of the social determinants of maternal depression.

METHODS

Critical realism provided the methodological underpinning for the study. The setting was four local government areas in South Western Sydney, Australia. Child and Family practitioners and mothers in naturally occurring mothers groups were interviewed.

RESULTS

Using an open coding approach to maximise emergence of patterns and relationships we have identified seven theoretical concepts that might explain the observed spatial clustering of maternal depression. The theoretical concepts identified were: Community-level social networks; Social Capital and Social Cohesion; "Depressed community"; Access to services at the group level; Ethnic segregation and diversity; Supportive social policy; and Big business.

CONCLUSIONS

We postulate that these regional structural, economic, social and cultural mechanisms partially explain the pattern of maternal depression observed in families and communities within South Western Sydney. We further observe that powerful global economic and political forces are having an impact on the local situation. The challenge for policy and practice is to support mothers and their families within this adverse regional and global-economic context.

Marcé International Society position statement on psychosocial assessment and depression screening in perinatal women

The position statement aims to articulate the arguments for and against universal psychosocial assessment and depression screening, and provide guidance to assist decision-making by clinicians, policy makers and health services. More specifically it: 1. Outlines the general principles and concepts involved in psychosocial assessment and depression screening; 2. Outlines the current debate regarding benefits and risks in this area of practice including the clinical benefits and the ethical, cultural and resource implications of undertaking universal psychosocial assessment in the primary health care setting; 3. Provides a document that will assist with advocacy for the development of perinatal mental health services in the primary care setting. The statement does not set out to make specific recommendations about psychosocial assessment and depression screening (as these will need to be devised locally depending on existing resources and models of care) nor does it attempt to summarise the vast evidence-base relevant to this debate.

Screening for perinatal depression

Perinatal depression is prevalent, under-diagnosed and can have serious long-term effects on the wellbeing of women, their partners and infants. In the absence of active identification strategies, most women with perinatal depression will neither seek nor receive help. To enable early detection and timely intervention, universal screening is coming to be seen as best practice in many settings. Although the strength of recommendations and the preferred methods of identification vary in different countries (e.g. the Edinburgh Postnatal Depression Scale, brief case-finding questions), appropriate training for health professionals in wider psychosocial assessment is essential to maximise usefulness while minimising potential harms. Clear pathways of systematic follow up of all positive screening results with a diagnostic procedure and access to effective treatment are centrally important both for the clinical effectiveness of screening and for health system costs. It is also necessary to further build on the emerging evidence base for the clinical effectiveness of screening.

Analysis of brief screening tools for the detection of postpartum depression: comparisons of the PRAMS 6-item instrument, PHQ-9, and structured interviews

Postpartum depression (PPD) is an important mental health issue affecting approximately 10 % of women. Self-report screening measures represent utility for detecting PPD in both clinical and research settings. The current study sought to inspect the accuracy of two screening measures compared to clinical interviews. As part of an ongoing clinical trial, 1,392 women between the ages of 18 and 45 were screened for PPD using the Patient Health Questionnaire-9 (PHQ-9) and a six-item scale developed from CDC Pregnancy Risk Assessment questions (PRAMS-6). Three item subscales of the PRAMS-6 were also inspected-three depression (PRAMS-3D) and three anxiety items (PRAMS-3A). Receiver operating characteristics compared the diagnostic accuracy of the PHQ-9, PRAMS-6, PRAMS-3D, and PRAMS-3A to both the Structured Clinical Interview for the DSM-IV (SCID) and the Hamilton Rating Scale for Depression. The PHQ-9, PRAMS-6, and PRAMS-3D all showed moderate accuracy at diagnosing PPD. Diagnostic cut points are provided. The PRAMS-6 instrument is a brief and effective screening tool for PPD. The time frame of symptom assessment may account for some variability in accuracy between the PHQ-9 and PRAMS screening instruments.

Maternal psychological factors and controlled child feeding practices in relation to child body mass index

BACKGROUND

The rise of childhood obesity in Western society has focused attention on parental feeding practices. Despite evidence that controlled feeding influences child weight, there is a paucity of research examining predictors of controlled feeding. The aim of this study was to determine whether maternal antenatal and/or concurrent anxiety and depressive symptoms, including stress, predicted controlled feeding and whether maternal controlled feeding practices, in turn, predict child BMI.

METHODS

In total, 203 mothers participated in a longitudinal follow-up survey. Mothers' self-reported symptoms of anxiety and depression were measured both in pregnancy and at 2-7 years postpartum. Maternal-reported child BMI and maternal use of restriction, pressure to eat, and monitoring were measured at 2-7 years postpartum.

RESULTS

Feeding practices were not uniformly predictive of child BMI. Maternal use of restriction and monitoring were partially positively predicted by concurrent maternal stress and negatively partially predicted by concurrent depression. Thus, mothers enduring high stress appeared to employ more controlled feeding patterns, whereas mothers experiencing depression seemingly employed lower levels of controlled feeding.

CONCLUSIONS

Findings that maternal anxiety and depression affect levels of controlled feeding are of particular interest and broadly supportive of the few existing studies. Given the mixed results linking controlled feeding to child BMI reported in previous research, further work is required to determine the relationships between maternal mood, child feeding practices, and BMI.

Antenatal stress: an Irish case study

BACKGROUND

stress in pregnancy is common and impacts negatively on women, infants and families. A number of factors contribute to high levels of stress in pregnancy, including financial concerns, marital discord, low support systems and low socio-economic status.

OBJECTIVES

the aim of this study was to evaluate stress anxiety levels and depressive symptoms among low risk women in an area in Ireland that was particularly impacted by the 2008 economic crisis.

DESIGN

a quantitative descriptive cross-sectional design was used. Data were collected using the Edinburgh Postnatal Depression Scale (EPDS), the Perceived Stress Scale and the State Trait Anxiety Inventory (STAI). Data was collected at a single time during the second trimester.

SETTING

this paper reports a case study of one maternity service in Ireland. Participants included low risk pregnant women who were attending the hospital clinic for routine antenatal care.

RESULTS

of 150 questionnaires distributed, 74 completed questionnaires were returned indicating a 49.3% return rate. Findings indicated high levels of stress, anxiety and depressive symptomatology among participants. There were no significant difference in mean EPDS score for different age groups (F4,69=2.48, P=0.052), living arrangements (F4,68=0.90, P=0.5) or usual occupation (F4,69=1.45, P=0.2). A score of ≥ 12 was taken as indicative of probable antenatal depression and 86.5% of participants responded with a score of 12 or above. PSS scores were also high and more than three quarters of respondents scored ≥ 15 (75.6%) and more than a third had scores ≥ 20 (35.1%), out of a total score of 40. There was a significant difference in mean PSS score between the different age groups (F4,69=3.60, P=0.010) but not for living arrangements or usual occupation. A STAI score of ≥ 39 was taken as indicative of antenatal anxiety, and 74.3% of participants responded with a score of 39 or above. There were no significant differences in mean STAI score between the different age groups (F4,68=1.68, P=0.16), living arrangements (F4,67=2.30, P=0.068) or usual occupations (F4,68=1.25, P=0.3).

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

this study found high levels of antenatal stress, anxiety, and depressive symptoms in a low risk pregnant population, in an economically impacted region in Ireland. These findings have implications for fetal development and maternal health during pregnancy and in the post partum. Further studies are important to confirm rates and should be conducted over a longer time frame with data collected at more than one point in time, such as mid and late pregnancy. If findings are confirmed, early recognition and treatment of stress, anxiety and depressive symptoms is important to ameliorate some of the harmful effects of these conditions.

Clinical validity of a brief measure of early childhood social-emotional/behavioral problems

OBJECTIVE

To address a pressing need for measures of clinically significant social-emotional/behavioral problems in young children by examining several validity indicators for a brief parent-report questionnaire.

METHODS

An ethnically and economically diverse sample of 213 referred and nonreferred 2- and 3-year-olds was studied. The validity of the Brief Infant-Toddler Social-Emotional Assessment (BITSEA) Problem Index and Internalizing and Externalizing scales was evaluated relative to a "gold standard" diagnostic interview, as well as the Child Behavior Checklist (CBCL).

RESULTS

The validity of the BITSEA Problem Index relative to Diagnosis (sensitivity = 72.7%-80.8%, specificity = 70.0%-83.3%) and clinical-range CBCL scores (sensitivity = 80.0%-96.2%, specificity = 75.0%-89.9%) was supported in the full sample and within minority/nonminority groups. Additional results supported the validity of the BITSEA Internalizing and Externalizing scales.

CONCLUSIONS

Documented validity suggests that the BITSEA may be a valuable tool to aid screening, identification, and assessment efforts targeting early-emergent social-emotional/behavioral problems. Practical implications and generalizability are discussed.

Detection of antenatal depression in rural HIV-affected populations with short and ultrashort versions of the Edinburgh Postnatal Depression Scale (EPDS)

Risk of antenatal depression has been shown to be elevated in Southern Africa and can impact maternal and child outcomes, especially in the context of the Human Immunodeficiency Virus (HIV). Brief screening methods may optimize access to care during pregnancy, particularly where resources are scarce. This research evaluated shorter versions of the Edinburgh Postnatal Depression Scale (EPDS) to detect antenatal depression. This cross-sectional study at a large primary health care (PHC) facility recruited a consecutive series of 109 antenatal attendees in rural South Africa. Women were in the second half of pregnancy and completed the EPDS and Structured Clinical Interview for Depression (SCID). The recommended EPDS cutoff (≥13) was used to determine probable depression. Four versions, including the 10-item scale, seven-item depression, and novel three- and five-item versions developed through regression analysis, were evaluated using receiver operating characteristic (ROC) analysis. High numbers of women 51/109 (47 %) were depressed, most depression was chronic, and nearly half of the women were HIV positive 49/109 (45 %). The novel three-item version had improved positive predictive value (PPV) over the 10-item version and equivalent specificity to the seven-item depression subscale; the novel five-item provided the best overall performance in terms of ROC and Cronbach's reliability statistics and had improved specificity. The brevity, sensitivity, and reliability of the short and ultrashort versions could facilitate widespread community screening. The usefulness of the novel three- and five-item versions are underscored by the fact that sensitivity is important at first screening, while specificity becomes more important at higher levels of care. Replication in larger samples is required.

Strategies for improving perinatal depression treatment in North American outpatient obstetric settings

OBJECTIVE

To identify core barriers and facilitators to addressing perinatal depression and review clinical, programmatic, and system level interventions that may optimize perinatal depression treatment.

METHOD

Eighty-four MEDLINE/PubMed searches were conducted using the terms perinatal depression, postpartum depression, antenatal depression, and prenatal depression in association with 21 other terms. Of 7768 papers yielded in the search, we identified 49 papers on barriers and facilitators, and 17 papers on interventions in obstetric settings aimed to engage women and/or providers in treatment.

RESULTS

Barriers include stigma, lack of obstetric provider training, lack of resources and limited access to mental health treatment. Facilitators include validating and empowering women during interactions with health care providers, obstetric provider and staff training, standardized screening and referral processes, and improved mental health resources.

CONCLUSION

Specific clinical, program, and system level changes are recommended to help change the culture of obstetric care settings to optimize depression treatment.

The prevalence of perinatal depression and its associated factors in two different settings in Brazil

BACKGROUND

The prevalence of antepartum and postpartum depression (PPD) and its association with certain risk factors was evaluated.

METHOD

The Edinburgh Postnatal Depression Scale (EPDS) was applied and sociodemographic data was obtained at the beginning of the third trimester of pregnancy and at 4-6 weeks postpartum.

RESULTS

The prevalence of depression was 24.3% during pregnancy (n=600 women) and 10.8% in the postpartum period (n=555). The factors independently associated with antepartum depression were the absence of a partner (PRadj 1.93; 95%CI: 1.44-2.58), a lower socioeconomic class (1.75; 1.18-2.60), being non-white (1.48; 1.09-2.01) and multiparity (1.32; 1.01-1.74). For postpartum depression, the factors were the occurrence of psychological violence (PRadj 3.31; 95%CI: 2.02-5.43), use of alcohol during pregnancy (2.14; 1.33-3.45), being non-white (1.85; 1.11-3.08) and physical violence (2.14; 1.13-4.08). The sensitivity of depression during pregnancy as a predictor of PPD was 75%, while specificity was 81%. There were no differences between the two settings.

LIMITATIONS

EDPS does not diagnose depression and as a screening instrument it could overestimate the true prevalence of depression.

CONCLUSIONS

The use of the EPDS instrument during pregnancy would allow a screening for identifying women at higher risk of developing PPD and then a proposal of specific interventions to manage this condition. Postpartum depression was prevalent in around 10% of the women and was associated with unfavorable sociodemographic conditions including the use of alcohol and with the occurrence of psychological and physical violence.

Detection and management of mood disorders in the maternity setting: the Australian Clinical Practice Guidelines

BACKGROUND

Mood disorders arising in the perinatal period (conception to the first postnatal year), occur in up to 13% of women. The adverse impact of mood disorders on mother, infant and family with potential long-term consequences are well documented. There is a need for clear, evidence-based, guidelines for midwives and other maternity care providers.

AIM

To describe the process undertaken to develop the Australian Clinical Practice Guidelines for Depression and Related Disorders in the Perinatal Period and to highlight the key recommendations and their implications for the maternity sector.

METHOD

Using NHMRC criteria, a rigorous systematic literature review was undertaken synthesising the evidence used to formulate graded guideline recommendations. Where there was insufficient evidence for recommendations, Good Practice Points were formulated. These are based on lower quality evidence and/or expert consensus.

FINDINGS

The quality of the evidence was good in regards to the use of the Edinburgh Postnatal Depression Scale and psychological interventions, but limited as regards medication use and safety perinatally. Recommendations were made for staff training in psychosocial assessment; universal screening for depression across the perinatal period; and the use of evidence based psychological interventions for mild to moderate depression postnatally. Good Practice Points addressed the use of comprehensive psychosocial assessment--including risk to mother and infant, and consideration of the mother-infant interaction--and gave advice around the use and safety of psychotropic medications in pregnancy and breastfeeding. In contrast to their international counterparts, the Australian guidelines emphasize a more holistic, woman and family centred approach to the management of mental health and mood disorders in the perinatal setting.

CONCLUSION

The development of these Guidelines is a first step in translating evidence into practice and providing Australian midwives and other maternity care providers with clear guidance on the psychosocial management of women and families.

Treating postnatal depressive symptoms in primary care: a randomised controlled trial of GP management, with and without adjunctive counselling

BACKGROUND

Postnatal depression (PND) is under-diagnosed and most women do not access effective help. We aimed to evaluate comparative management of (PND) following screening with the Edinburgh Postnatal Depression Scale, using three best-practice care pathways by comparing management by general practitioners (GPs) alone compared to adjunctive counselling, based on cognitive behavioural therapy (CBT), delivered by postnatal nurses or psychologists.

METHODS

This was a parallel, three-group randomised controlled trial conducted in a primary care setting (general practices and maternal & child health centres) and a psychology clinic. A total of 3,531 postnatal women were screened for symptoms of depression; 333 scored above cut-off on the screening tool and 169 were referred to the study. Sixty-eight of these women were randomised between the three treatment groups.

RESULTS

Mean scores on the Beck Depression Inventory (BDI-II) at entry were in the moderate-to-severe range. There was significant variation in the post-study frequency of scores exceeding the threshold indicative of mild-to-severe depressive symptoms, such that more women receiving only GP management remained above the cut-off score after treatment (p = .028). However, all three treatment conditions were accompanied by significant reductions in depressive symptoms and mean post-study BDI-II scores were similar between groups. Compliance was high in all three groups. Women rated the treatments as highly effective. Rates of both referral to the study (51%), and subsequent treatment uptake (40%) were low.

CONCLUSIONS

Data from this small study suggest that GP management of PND when augmented by a CBT-counselling package may be successful in reducing depressive symptoms in more patients compared to GP management alone. The relatively low rates of referral and treatment uptake, suggest that help-seeking remains an issue for many women with PND, consistent with previous research.
