Demographic characteristics of participants in studies of risk factors, prevention, and treatment of postpartum depression

Risk factors for postpartum depression among sexual minority and heterosexual parents

OBJECTIVE

Postpartum depression (PPD), a major depressive episode with postpartum onset, develops in 15% of mothers. Although findings suggest sexual minority parents may be at risk for PPD, research among this population is scarce. We evaluated risk factors for PPD in a sample of sexual minority and heterosexual parents.

METHOD

Four hundred and twenty seven heterosexual and one hundred and eleven sexual minority parents responded to a questionnaire distributed via social media that included demographics, the Edinburgh Postnatal Depression Scale, and the Multidimensional Scale of Perceived Social Support.

RESULTS

Sexual minority identity was not associated with increased risk for PPD. Pregnancy had no significant effect on the likelihood for PPD. Social support was negatively and significantly associated with probability for PPD.

CONCLUSIONS

Our data suggest that sexual minority parents are not at increased risk for PPD, contrary to previous findings. The parental role, a psychosocial factor, is a more dominant risk factor than pregnancy itself, in the development of PPD.

Antepartum sleep quality, mental status, and postpartum depressive symptoms: a mediation analysis

BACKGROUND

Poor sleep quality and maternal mood disturbances are common during pregnancy and may play pivotal roles in the development of postpartum depression. We aim to examine the trajectories of sleep quality and mental health in women from early pregnancy to delivery and explore the mediating effects of sleep quality and mental status on the link between antepartum depressive symptoms and postpartum depressive symptoms.

METHODS

In an ongoing prospective birth cohort, 1301 women completed questionnaires in the first, second and third trimesters and at 6 weeks postpartum. In each trimester, sleep quality was measured utilizing the Pittsburgh Sleep Quality Index (PSQI), and mental health was assessed with the Center for Epidemiologic Studies Depression Scale (CES-D), the Self-Rating Anxiety Scale (SAS) and the Perceived Stress Scale (PSS). Postpartum depressive symptoms were evaluated by the Edinburgh Postnatal Depression Scale (EPDS). The bootstrap method was used to test the mediation effect.

RESULTS

The PSQI, CES-D, and SAS scores presented U-shaped curves across the antenatal period while the PSS score followed a descending trend. Antenatal sleep quality, depressive symptoms, anxiety symptoms and perceived stress all predicted depressive symptoms at 6 weeks postpartum. The influence of antepartum depressive symptoms on postpartum depressive symptoms was mediated by antepartum sleep quality and anxiety symptoms, which accounted for 32.14%, 39.25% and 31.25% in the first, second and third trimesters (P = 0.002, P = 0.001, P = 0.001, respectively).

CONCLUSIONS

Poor sleep quality and anxiety symptoms in pregnancy mediated the relationship between antepartum depressive symptoms and postpartum depressive symptoms. Interventions aimed at detecting and managing sleep quality and elevated anxiety among depressed women in pregnancy warrant further investigation as preventative strategies for postpartum depression.

Optimism as a mediator of the association between social support and peripartum depression among mothers of neonatal intensive care unit hospitalized preterm infants

The birth of a preterm infant and the hospitalization in a neonatal intensive care unit (NICU) add extra functional and emotional demands to the typical transition to motherhood. Therefore, the prevalence of peripartum depression (PPD) among preterm mothers is especially high. As optimism was found to be a mediator of the association between social support and depression, the current study aimed to test this mediation in the population of NICU mothers. A sample of 128 Israeli mothers of 214 NICU hospitalized infants filled out self-report questionnaires regarding background variables, social support, optimism, and PPD symptoms. As hypothesized, optimism was found to partially mediate the association between social support and PPD symptoms among mother of preterm infants. The higher the perceived social support reported, the higher maternal optimism reported, and in turn, the lower PPD symptoms reported. In accordance with the Transactional Stress Theory, social support and optimism reflect maternal secondary appraisals that impact the way mothers of preterm infants cope with the challenging situation of a preterm birth and NICU hospitalization. Healthcare professionals should encourage preterm mothers' use of social support to increase optimism and reduce the risk of developing PPD.

What Is Being Measured? A Comparison of Two Depressive Symptom Severity Instruments with a Depression Diagnosis in Low-Income High-Risk Mothers

BACKGROUND

Adequate assessment of depressive symptomatology is a necessary step toward decreasing income-related mental health treatment inequity. No studies have focused on comparing instruments used to detect depression in women from low-income backgrounds who are mothers of young children-a period of increased risk for depressive symptoms.

METHODS

To address this gap, two commonly used instruments (Center for Epidemiologic Studies Depression Scale [CES-D] and Hamilton Rating Scale for Depression [Hamilton]) were compared with a depression diagnosis (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [DSM-V]) in a sample (n = 251) of mothers from low-income backgrounds with children ranging from 1 to 54 months old. Diagnostic utility was examined in light of contextual factors associated with maternal depressive symptoms.

RESULTS

In this sample, CES-D had better screening sensitivity and specificity than Hamilton. Our results suggest that Hamilton may underdiagnose cases of major depressive episodes (MDE) as defined by DSM-V among black and low-income mothers compared with CES-D. In addition, we identify items in CES-D, which do not contribute to alignment with DSM-V and are appropriate targets for future improvements. Our analysis identifies interpersonal relationships and mother's age as the primary risk factors, which differentiate between CES-D and Hamilton determinations versus MDE diagnosis. In addition, we find regional differences in CES-D and Hamilton.

CONCLUSIONS

It is important to tailor the measure to the context, and a calibration sample should be considered for studies of sufficient size.

Disturbed Sleep and Postpartum Depression

The perinatal period introduces a myriad of changes. One important but often overlooked change is an increased reporting of sleep disturbance. Although casually regarded as a consequence of pregnancy or postpartum, there is emerging evidence implicating significant sleep disturbance, characterized by insomnia symptoms and/or poor sleep quality, with adverse outcomes, such as an increase in depressive symptomatology or the development postpartum depression (PPD). Significant consequences may arise as a result including issues with maternal-infant bonding, effective care for the infant, and behavioral or emotional difficulties in the infant. This review discusses the relevant literature as to how disturbed sleep during pregnancy as well as in the postpartum may increase the risk for PPD.

Postpartum depression among visible and invisible sexual minority women: a pilot study

PURPOSE

Significant numbers of sexual minority women are choosing to parent. Despite this, there is limited research on postpartum depression (PPD) with sexual minority mothers and less research considering differences within sexual minority women in the experience of PPD. This research examines two questions to address this gap in research: (1) Do experiences of PPD symptoms vary between different subgroups of sexual minority women, and (2) Which recruitment strategies effectively address the challenge of recruiting sexual minority women who are pregnant?

METHODS

Two Canadian studies recruited participants via consecutive or convenience sampling from midwifery clinics and hospital sites. Participants completed prenatal and postnatal measures of PPD symptoms, social support, and perceived discrimination.

RESULTS

Considering our first question, we found an interaction effect between past sexual behavior and current partner gender. Women currently partnered with men reported higher scores on the Edinburgh Postpartum Depression Scale when their sexual history included partners of more than one gender, whereas this effect was not found among women who were currently partnered with women or not partnered. Regarding our second question, most sexual minority participants recruited through convenience sampling were partnered with women and identified as lesbian or queer, while most participants recruited through consecutive sampling were partnered with men and identified as bisexual.

CONCLUSIONS

Women whose sexual histories include more than one gender and are currently partnered with men may be at a higher risk for PPD symptoms. Recruitment method may influence the type of sample recruited for perinatal mental health research among sexual minority women.

Postpartum Mental Health in First-Time Mothers: A Cohort Study

Background

Post-partum depression (PPD) can produce adverse symptoms that make motherhood one of the most tumultuous events in a female’s life. First-time mothers who have problems adapting themselves to the mother’s role are more vulnerable to PPD.

Objectives

The current study aimed to explore the extent of social support and parental self-efficacy on PPD, this study was conducted among the first-time pregnant women.

Patients and Methods

A prospective cohort study assessed the depressive symptoms and related factors among 838 first-time not depressed pregnant women from third trimester of pregnancy to 12 weeks postpartum who attended primary health centers (Jan to July 2009). The study employed Edinburgh postnatal depression scale, social support appraisals scale, network orientation scale, marital inventory, parental expectation survey and socio-demographic questionnaires. Logistic regression was used for data analysis.

Results

The incidence of depression was 10.7% at three months post-partum. The adjusted odds ratio showed the PPD was associated with perceived social isolation (OR = 1.06; 95% CI = 1.01 - 1.12), lack of marital satisfaction (OR = 0.91; 95% CI = 0.86 - 0.97) and low parental self-efficacy (OR = 0.74; 95% CI = 0.65 - 0.85).

Conclusions

A high incidence of PPD was identified among the first-time mothers which makes PPD one of the major health problems in females. The important effects of perceived social isolation, maternal parental self-efficacy, and marital satisfaction on reducing the risk of PPD should be considered.

Sleep and postpartum depression

PURPOSE OF REVIEW

The perinatal period introduces a myriad of changes. One important but often overlooked change is the increased risk for sleep disturbance. Although casually regarded as a consequence of pregnancy or postpartum, there is emerging evidence to suggest that women with significant sleep disturbance, characterized by insomnia symptoms and/or poor sleep quality, are more likely to report an increase in depressive symptomatology or develop postpartum depression (PPD). Significant consequences may arise as a result including issues with maternal-infant bonding, effective care for the infant and behavioral or emotional difficulties in the infant. This review discusses the relevant literature as to how disturbed sleep during pregnancy as well as in the postpartum may increase the risk for PPD.

RECENT FINDINGS

Symptoms of insomnia and poor sleep quality are independently associated with greater depressive symptoms across pregnancy and throughout postpartum. Likewise, both can negatively impact the ability to mother effectively.

SUMMARY

The presence of insomnia or sleep disturbance during the perinatal period is a risk factor for depressive symptoms. Women with depression are at an increased risk of developing sleep disturbance thereby increasing depressive symptomatology. This bidirectional and additive relationship needs more clinical attention as both sleep disturbance and depression are noted risk factors for adverse pregnancy outcomes.

An Exploration of Parenting Stress in Immigrant and Taiwanese Mothers

To assess parenting stress and major difficulties experienced in early motherhood among immigrant and Taiwanese women in Pingtung, southern Taiwan. A comparative, descriptive, cohort study of parenting stress and maternal psychological health, using the Child Care Stress Checklist and Edinburgh Postpartum Depression Scale. A purposive sample of 26 foreign-born Vietnamese and 162 Taiwanese mothers were surveyed at 6 weeks' postpartum. Both groups of mothers experienced similar parenting difficulties including the establishment of a regular sleeping schedule for the infant, consoling a crying infant, awareness of infant's needs, conflict with family members, and difficulties managing household chores. Curtailment of social activities was reported more often by Taiwanese mothers, whereas inaccessibility to other experienced mothers and poor maternal-infant bonding were experienced more by immigrant mothers. There were significant differences between groups, with high levels of child care stress and postpartum depression symptoms reported more often by immigrant mothers. Nurses-midwives and community child health nurses need to be sensitive to the particular difficulties and stresses of parenting in mothers from different backgrounds and provide effective interventions and support activities.

Risk factors and course patterns of anxiety and depressive disorders during pregnancy and after delivery: a prospective-longitudinal study

BACKGROUND

Peripartum anxiety and depressive disorders are associated with adverse consequences for mother and child. Thus, it is important to examine risk factors, correlates and course patterns of anxiety and depressive disorders during pregnancy and after delivery.

METHODS

In the prospective-longitudinal Maternal Anxiety in Relation to Infant Development (MARI) Study, n=306 expectant mothers were recruited from gynaecological outpatient settings in Germany and completed up to seven waves of assessment from early pregnancy until 16 months postpartum. Anxiety and depressive disorders and potential risk factors/correlates were assessed with the Composite International Diagnostic Interview for Women (CIDI-V), medical records and additional questionnaires.

RESULTS

Although peripartum anxiety and depressive disorders appeared to be persistent in some women, others reported major changes with heterogeneous courses and shifts between diagnoses and contents. There was a considerable amount of incident disorders. Strongest predictors for peripartum anxiety and depressive disorders were anxiety and depressive disorders prior to pregnancy, but psychosocial (e.g. maternal education), individual (e.g. low self-esteem), and interpersonal (e.g. partnership satisfaction, social support) factors were also related.

LIMITATION

Knowing the aims of the study, some participants may have been more encouraged to report particular symptoms, but if so, this points to the importance of a comprehensive assessment in perinatal care.

CONCLUSION

Peripartum time is a sensitive period for a considerable incidence or persistence/recurrence of anxiety and depressive disorders albeit the course may be rather heterogeneous. Interventional studies are needed to examine whether an alteration of associated factors could help to prevent peripartum anxiety and depressive disorders.

Depressive symptoms and proinflammatory cytokines across the perinatal period in African American women

BACKGROUND

Comparatively few studies have examined the biological mechanisms that may underlie the reported racial disparities in antenatal and postpartum depression.

OBJECTIVE

To examine the associations among race, depressive symptoms and the proinflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α across the perinatal period in a diverse sample of healthy pregnant women at elevated psychosocial risk.

METHODS

171 subjects were enrolled. Women were interviewed and blood samples drawn at 18 and 32 weeks gestation and 6 weeks and 6 months postpartum. Depressive symptoms were measured using the Edinburgh Postnatal Depression Scale. Serum levels of IL-6 and TNF-α were assayed using high sensitivity enzyme-linked immunosorbent assay kits.

RESULTS

Compared with non-African American (AA) women, AA women had significantly higher levels of IL-6 (est. diff = 0.521, p = 0.02, confidence interval (CI): 0.088-0.954) but not TNF-α across all time points (est. diff = -0.060, p = 0.80, CI: -0.517 to 0.397). IL-6 was not associated with depressive symptoms but differences in IL-6 were accounted for by greater Body Mass Index in AA women.

CONCLUSIONS

Compared with non-AA women, AA women entered pregnancy with elevated inflammatory cytokine levels that persisted across the perinatal period. This group difference in inflammation did not suggest increased risk for depression, but suggests other implications for long-term health.

Identifying features of bipolarity in patients with first-episode postpartum depression: findings from the international BRIDGE study

OBJECTIVES

The aims of this study were to assess rates of bipolar spectrum disorders in women experiencing their first episode of postpartum depression, and to find out features indicative of bipolarity in these patients.

METHODS

As part of the international BRIDGE study designed to detect hypo/mania in patients with a major depressive episode, 52 (5.85%) were found to experience a first episode of postpartum (FEPP) depression, whereas 833 (94.13%) had a first episode of nonpostpartum (FENPP) depression. Hypo/mania was assessed using varying definitions of bipolarity, and the two groups compared on sociodemographic, family history and clinical characteristics.

RESULTS

Compared to FENPP depressive patients, women with FEPP depression had higher rates of bipolar disorders, with more hypo/mania in first degree relatives. Psychotic symptoms, atypical features, mixed depression, younger age at onset, high number of prior episodes, episodes of short duration, switches on antidepressants, seasonality of mood episodes as well as mood episodes with free intervals were found to be more frequent in FEPP depressives.

LIMITATIONS

The following are the limitations of this study: centres not randomly selected, recall bias, cross-sectional design, and limited training of participating psychiatrists.

CONCLUSIONS

This study confirms, in women experiencing a first depressive episode, high rates (15 to 50%) of bipolar disorders during the postpartum period and is the first to systematically assess and demonstrate the higher prevalence of identifying features of bipolarity in FEPP versus FENPP depression. Early recognition of bipolarity in these patients may help prevent the harmful consequences of this illness.

Interaction of maternal age and mode of delivery in the development of postpartum depression in Yerevan, Armenia

BACKGROUND

To investigate determinants of development of postpartum depression among women in Yerevan, Armenia.

METHOD

A case-control study of all reproductive age (18-45) women having 1-3 months old children registered in 7 Primary Health Care (PHC) facilities, in Yerevan. We used Edinburgh Postnatal Depression Scale (EPDS) and a structured questionnaire to assess possible postpartum depression status of mothers and exposure status through telephone interviews.

RESULTS

The study had a 96.7% response rate for 63 cases and 272 controls. The prevalence of possible postpartum depression was 14.4%. The risk of possible postpartum depression associated with age less than 25 years at childbirth was increased only among women who delivered their child through C-section (OR=7.8; 95% CI: 1.5-40.7). Meanwhile, this risk was much lower among women who delivered through vaginal delivery (OR=0.9; 95% CI: 0.4-1.8).

LIMITATIONS

EPDS had not been translated and validated in Armenia. Study population included only women having 1-3 months old children.

CONCLUSION

The study suggested that the effect of younger age at last childbirth on the risk of possible postpartum depression development was higher for women who gave birth through C-section compared to those with vaginal delivery. Despite the stressful and crisis conditions existing in Armenia over the past 2 decades the prevalence of possible postpartum depression does not differ much from that in other societies.

Psychiatric symptoms and proinflammatory cytokines in pregnancy

OBJECTIVE

Clinical studies suggest that psychiatric symptoms, particularly depression, anxiety, and trauma, may be associated with inflammation, as indexed by proinflammatory cytokines. Such a link may be especially significant in pregnancy and may shed additional light on the etiology of perinatal mood disorders.

METHODS

We prospectively observed 145 women selected from a community obstetric clinic serving a primarily low-income, high-psychosocial risk population. Women without evidence of medical high-risk pregnancies were screened (including psychiatric and trauma histories) and then assessed in detail (e.g., mood symptoms) at approximately 18 and 32 weeks' gestation. Blood was drawn to measure key proinflammatory markers, interleukin 6 and tumor necrosis factor α (TNF-α). Data on pregnancy and obstetric outcome were derived from medical records.

RESULTS

There was considerable stability of cytokine levels within individuals and a significant mean increase across pregnancy observed for interleukin 6 (p < .001) and TNF-α (p < .001). History of trauma was associated with significantly elevated TNF-α levels (F(1,135) = 4.43, p < .05), controlling for psychosocial and obstetric covariates. In contrast, elevated measures of depression and anxiety were unrelated to proinflammatory cytokines (p > .1). Exploratory analyses indicated that neither psychiatric symptoms nor proinflammatory cytokines predicted birth weight, gestational age, or obstetric complications.

CONCLUSIONS

These findings suggest that antecedent trauma may be associated with persistently elevated TNF-α levels during pregnancy. The evidence that a generalized proinflammatory state was associated with symptoms of depression or anxiety in pregnant women was not found.

Prevalence rates and socioeconomic characteristics of post-partum depression in Hungary

The rapid socioeconomic transition in post-communist Hungary adversely affected the overall morbidity and mortality rates in the 1990s. Prevalence data on depressive disorders from the region are still scarce, however. This study reports the findings of the first epidemiological survey, using the Edinburgh Postnatal Depression Scale (EPDS) and the Beck Depression Inventory (BDI), on the prevalence of post-partum depression and the associated risk factors in Hungary. A total of 1030 mothers who delivered their babies between May and July 1999 in 16 counties in Hungary were screened for depressive symptoms 3-26 weeks post-partum. The survey found that 10.81% of the sample was above the cut-off score of 13, and the EPDS detected post-partum depressive symptoms with 76% (95% confidence interval (CI)=60.5-87.1) sensitivity and 92% (95% CI=90.5-94.1) specificity. In addition, 24 socio-demographic, socio-psychiatric data and personal and obstetric variables were surveyed. Results of a hierarchical logistic regression analysis showed that depression of the mother during pregnancy was the strongest predictor of depressive symptoms post-partum. Depression before pregnancy, housing conditions, marital relationship status and family history of alcohol problems were also identified as predictors for post-partum depressive symptoms.

How much does low socioeconomic status increase the risk of prenatal and postpartum depressive symptoms in first-time mothers?

OBJECTIVE

To examine socioeconomic status (SES) as a risk factor for depressive symptoms in late pregnancy and the early postpartum period. A secondary objective was to determine whether SES was a specific risk factor for elevated postpartum depressive symptoms beyond its contribution to prenatal depressive symptoms.

DESIGN

Quantitative, secondary analysis, repeated measures, descriptive design.

SETTING

Participants were recruited from paid childbirth classes serving upper middle class women and Medicaid-funded hospitals serving low-income clients in Northern California.

PARTICIPANTS

A sample of 198 first-time mothers was assessed for depressive symptoms in their third trimester of pregnancy and at 1, 2, and 3 months postpartum.

MAIN OUTCOME MEASURE

Depressive symptoms were measured with the Center for Epidemiological Studies-Depression (CES-D) Scale.

RESULTS

Low SES was associated with increased depressive symptoms in late pregnancy and at 2 and 3 months, but not at 1 month postpartum. Women with four SES risk factors (low monthly income, less than a college education, unmarried, unemployed) were 11 times more likely than women with no SES risk factors to have clinically elevated depression scores at 3 months postpartum, even after controlling for the level of prenatal depressive symptoms.

CONCLUSION

Although new mothers from all SES strata are at risk for postpartum depression, SES factors including low education, low income, being unmarried, and being unemployed increased the risk of developing postpartum depressive symptoms in this sample.

Predictors of maternal depression in the first year postpartum: marital status and mediating role of relationship quality

Existing literature has documented the associations between marital status and maternal depression within the first year postpartum. Using data that is representative of urban non-marital births in the United States with a large over-sample of non-marital births, we investigate the association of maternal depression with not only marital status but also relationship quality with the father of the baby. Quality is independently associated with maternal depression after controlling for marital status and other variables that have been documented as risk factors for maternal depression. In addition, relationship quality explains away the associations between marital status and maternal depression. After controlling for relationship quality, single women were no more likely to be depressed compared to married or cohabiting women.

Risk factors for postpartum depression: the role of the Postpartum Depression Predictors Inventory-Revised (PDPI-R). Results from the Perinatal Depression-Research & Screening Unit (PNDReScU) study

The aims of this study were to identify the frequency of the risk factors for postpartum depression (PPD) listed in the Postpartum Depression Predictors Inventory-Revised (PDPI-R) during pregnancy and 1 month after delivery and to determine the predictive validity of the PDPI-R. The study used a prospective cohort design. Women completed the PDPI-R at the 3rd and the 8th months of pregnancy and at the 1st month after childbirth. Women were prospectively followed across three different time points during the postpartum using Structured Clinical Interview for DSM-IV Disorders to determine the presence of major or minor depression. The prenatal version of the PDPI-R administered at two different time points during pregnancy predicted accurately 72.6% and 78.2% of PPD and the full version administered at the 1st month after delivery predicted 83.4% of PPD. The cutoffs identified were 3.5 for the prenatal version and 5.5 for the full version. The PDPI-R is a useful and a valid screening tool for PPD.

Depression in Mongolian women over the first 2 months after childbirth: prevalence and risk factors

BACKGROUND

Social, political and economic changes in Mongolia have followed post-Soviet style government policies and contributed to both increased liberalisation and reduced security in employment and family finances. This is the first study to attempt to assess the prevalence of depression in a population of Mongolian women in the post-partum period and assess risk factors, including financial position, associated with the condition.

METHODS

A total of 1044 women who had delivered healthy babies in Ulaanbaatar between October and December 2002 were screened for depression using the WHO Self Reporting Questionnaire between 5 and 9 weeks post-partum. Further details on the mother, her family and social and economic circumstances were simultaneously collected. Analysis of risk factors for probable depression was undertaken using multiple logistic regression techniques.

RESULTS

The prevalence of depression was 9.1% (95% CLs 7.5%-11.1%). Variables significantly and independently associated with risk of probable maternal depression included economic factors, mother being subject to physical abuse, dissatisfied with the pregnancy, concerned about her baby's behaviour, and her own health problems.

LIMITATIONS

The sample was drawn from a population of mothers all of whom had healthy, full-term babies of normal birth weight. Clinical confirmation of diagnosis was not established.

CONCLUSIONS

Mongolian women with young infants in Ulaanbaatar probably experience depression at rates comparable with other cultures. Factors associated with probable depression were dominated by health, relationships and financial position.

Socioeconomic status and anxiety as predictors of antidepressant treatment response and suicidal ideation in older adults

BACKGROUND

Separate reports from the maintenance treatment for late-life depression (MTLD) trials have shown that low socioeconomic status (SES) and anxiety symptoms at the time of treatment initiation predict lower levels of response to antidepressant treatment and higher levels of suicidal ideation in older adults.

AIM

To determine whether SES and anxiety independently contribute to worse treatment outcomes, as indicated by persistence of depressive symptoms during treatment and the persistence of suicidal ideation. Consistent with prior evidence that sociodemographic factors and clinical history are both prognostic of depression treatment efficacy, we hypothesized that SES and pre-existing anxiety symptoms will both predict lower levels of response to treatment and higher levels of suicidal ideation.

METHOD

Secondary analyses of data from the MTLD trials.

RESULTS

Regression analyses which controlled for comorbid anxiety indicated that residents of middle- and high-income census tracts were more likely to respond to treatment (HR, 1.63; 95%CI, 1.08-2.46) and less likely to report suicidal ideation during treatment (OR, 0.51; 95%CI, 0.28-0.90) than residents of low income census tracts. The same regression models indicated that pre-existing anxiety symptoms were independently related to lower treatment response (HR, 0.73; 95%CI, 0.60-0.89) and higher risk of suicidal ideation (OR, 1.45; 95%CI, 0.98-2.14).

CONCLUSION

These findings demonstrate the importance of treating anxiety symptoms during the course of treatment for late-life depression and, at the same time, addressing barriers to treatment response related to low SES.

Sleep complaints in late pregnancy and the recurrence of postpartum depression

This study evaluated the relationship between sleep quality in late pregnancy and recurrence of postpartum major depression (PPMD) through 28 weeks postpartum. The Pittsburgh Sleep Quality Index (PSQI) at 36 weeks gestation was assessed in 51 non-depressed women with a history of PPMD; recurrence was determined by the 21-item Hamilton Rating Scale for Depression and the Schedule for Affective Disorders and Schizophrenia. Sleep quality in late pregnancy was not related to recurrence per se, but it was related to timing of recurrence (Kruskal-Wallace = 9.78, p = .008). Rapid recurrence (within 4 weeks post delivery) was preceded by fewer sleep complaints (mean PSQI for early recurrers = 4.8 vs. 7.3 for non-recurrers, p = .09). Recurrence after 4 weeks postpartum was preceded by more sleep complaints in late pregnancy (mean PSQI for late recurrers = 9.9 vs. 7.3 for non-recurrers, p = .02). Sleep quality in late pregnancy may help in identifying women at risk for a PPMD recurrence.

A depressive symptoms responsiveness model for differentiating fatigue from depression in the postpartum period

Fatigue is both a symptom and a predictor of depression in women after childbirth. At the same time, postpartum fatigue is experienced by most non-depressed women. Health care providers experientially know that not all women who experience postpartum fatigue will manifest depression. However, while researchers agree that fatigue and depression are distinct concepts, they have not yet identified a means for describing or measuring this distinctness. A new model proposing how fatigue may be differentiated from depression after childbirth is presented. The Depressive Symptoms Responsiveness Model proposes that depression-related postpartum fatigue may potentially be differentiated from non-depression-related postpartum fatigue on the basis of whether depressive symptoms abate when fatigue is relieved. The ability to differentiate between fatigue and depression in postpartum women has the potential to improve women's health through improvements in practice and resource utilization. Furthermore, differentiation may lead to a better understanding of the role of fatigue in postpartum depression.

Early adverse emotional response to childbirth in Turkey: the impact of maternal attachment styles and family support

Early adverse emotional response which is often detected in the form of depressive symptoms is a predictor of postpartum depression following the birth. The aim of our study is to highlight contextual and individual factors that have an impact on mothers' depressive symptoms during the early postpartum period. One hundred mothers participated in the study. Maternal depressive symptoms were screened by Edinburgh Postpartum Depression Scale (EPDS), and maternal anxiety level was assessed by State-Trait Anxiety Inventory (STAI) at early postpartum period (7-10 days). The Multidimensional Scale of Perceived Social Support (MSPSS) was used for the assessment of maternal social support. The Adult Attachment Scale (AAS) was used to determine the attachment style of the mother. The mean EPDS score of mothers who live in extended families is found to be significantly lower than others who live in nuclear families (extended families 7.13+/-7.39, nuclear families 11.77+/-5.96, p=0.006). Significant positive correlations were found between EPDS total scores and ambivalent attachment style group (r=.0436, p=.000), and avoidant attachment style group (r=.328, p=.001). The level of perceived family support also showed a negative correlation with EPDS total score (r=-.363, p=.000). The regression of EPDS total score with ambivalent attachment style and state anxiety level are positively predicted and the level of perceived family support and existence of wider social network negatively predict the EPDS total score in the first postpartum week. Maternal attachment patterns, living with the extended family and existence of family support have an important impact on early postpartum emotional adaptation. Early intervention strategies should count towards these individual and contextual factors when designing screening and preventive interventions for postpartum depression.

Healthcare worker's perceptions of barriers to care by immigrant women with postpartum depression: an exploratory qualitative study

OBJECTIVE

We interviewed healthcare workers working in Toronto, Canada, regarding their experience of providing care to recent immigrant women suffering from postpartum depression. The objective was two-fold: 1) to identify potential barriers to care that recent immigrant women may encounter as perceived by healthcare workers; and 2) to identify challenges healthcare workers felt that they faced as providers of care to this population.

METHODS

Qualitative semi-structured interviews were conducted with 16 key informants from various disciplines employed by healthcare agencies providing care to postpartum immigrant women in Toronto. Constant comparative analysis was used to analyze the data.

RESULTS

Two main categories of barriers to care for recent immigrant women were identified: 'practical barriers' and 'culturally determined barriers'. Practical barriers included knowing where and how to access services, and language difficulties. Cultural barriers included fear of stigma and lack of validation of depressive symptoms by family and society. The challenges experienced by healthcare providers working with this population were organized into two other categories: 'professional limitations', and 'social/cultural barriers'. 'Professional limitations' included fear of incompetence, language barriers, and inadequate assessment tools. 'Social/cultural barriers' included the experience of cultural uncertainty.

CONCLUSIONS

The results suggest that not only are there important barriers to accessing postpartum care for recent immigrant women, but it can also be challenging for healthcare workers to deliver such needed care. Understanding some of these barriers and challenges from the perspective of healthcare providers is an important step to remedying gaps and obstacles in the service system.

Income inequalities and self-reported maternal health status: cross-sectional national survey

The objective of this study was to examine income inequalities in the self-reported health status of women during the postnatal period. We analysed data from a cohort of 18,523 birth mothers of children who participated in the Millennium Cohort Study. Data on income and self-reported health status were collected during face-to-face interviews conducted at 9 months postpartum. Total take-home household income from employment, government and other sources was estimated and equivalised to reflect household composition, while self-reported health status was converted into a dichotomous measure. Complex survey logistic regression models were used to explore the association between equivalised household income and fair or poor self-reported health status. Compared with mothers with equivalised household income in the first quintile (bottom 20%) of the income distribution, mothers in the third (OR 0.69; 95% CI 0.59-0.81), fourth (OR 0.43; 95% CI 0.38-0.50) and fifth (OR 0.32; 95% CI 0.27-0.37) quintiles had a decreased likelihood of reporting fair or poor health status (P < 0.001). However, following adjustment for other predictors of postnatal health status, only mothers with equivalised household income in the fifth quintile (top 20%) had a decreased likelihood of reporting fair or poor health status (OR 0.72; 95% CI 0.58-0.90; P = 0.004). We conclude that this study provides support for the existence of an income gradient for postnatal health status. Efforts to reduce income inequalities in adverse maternal health outcomes are likely to require macro and microeconomic initiatives.
