HIV-infected mothers’ perceptions of uncertainty,stress, depression and social support during HIV viral testing of their infants

To explore relationships between mothers’ uncertainty about infant HIV serostatus with stress, distress, depressive symptoms, and social support during infant HIV testing. This prospective longitudinal study of 20 HIV-infected mothers involved a prenatal visit and five postpartum visits clustered around infant HIV viral testing. Maternal uncertainty about infant HIV serostatus significantly decreased over time (p < 0.001). Before testing, uncertainty was inversely related to social support (r = −0.67), and positively related to perceived stress (r = 0.54), interpersonal social conflict (r = 0.57), symptom distress (r = 0.62), and depressive symptoms (r = 0.50); these relationships persisted throughout the infant testing period. Mothers with depressive symptoms during pregnancy demonstrated significantly more uncertainty within a few weeks after birth than mothers without depressive symptoms (p < 0.05). Several weeks after learning their infants were HIV negative, mothers’ uncertainty was only associated with social conflict (r = 0.49). Maternal uncertainty about infant HIV status declined significantly over time. There were no changes in perceptions of stress, distress or social support. Mothers with depressive symptoms experienced greater uncertainty about infants’ HIV status. Strategies to enhance support and treat depressive symptoms may reduce the uncertainty, stress, and distress HIV-infected mothers experience during viral testing of their infants.     

2019-nCOV distress and depressive,anxiety and OCD-type,and eating disorder symptoms among postpartum and control women

This study compared postpartum and control women on depressive, anxiety, and OCD-type symptoms, and eating disorder symptoms during the 2019-nCOV pandemic and evaluated if associations between 2019-nCOV distress and these mental health symptoms differed for postpartum compared to control women. A community sample of women, ages 18–39, who had either given birth in the past 12 months (n = 232) or had no pregnancy history (n = 137; controls), was recruited to complete an online survey about their depressive, anxiety, OCD, and eating disorder symptoms. Postpartum women reported greater OCD-type symptoms related to concerns about both contamination and responsibility for harm (ps < .05) compared to controls. After controlling for general stress and mental health history, the association between 2019-nCOV distress and OCD-type symptoms related to concerns about contamination was stronger among postpartum compared to control women (ps < .002). For all women, 2019-nCOV distress was positively related to general anxiety symptoms, total OCD-type symptoms, and OCD-type symptoms related to concerns about responsibility for harm after controlling for general stress and mental health history (ps < .03). Data are first to suggest postpartum women may be at elevated risk for OCD-type symptoms during 2019-nCOV pandemic, and pandemic distress is associated with anxiety and OCD-type symptoms among postpartum women more so than control women.

     

Stability and change in depressive symptoms from pregnancy to two months postpartum in childbearing immigrant women

Summary The present study explored changes in mental health and functional status from pregnancy to 2 months postpartum in a sample of 106 childbearing immigrant women. Three sets of variables were examined in relation to postpartum depressive symptomatology: (1) prenatal depression, worries, and somatic symptoms; (2) social relationships (marital quality and social support), and (3) factors related to migration (premigration stress and length of stay in the host country). We found that 37.7% of the women in this community sample scored above the cutpoint of 12 on the Edinburgh Postnatal Depression Scale; prenatal depressive and somatic symptoms, as well as marital quality, were the best predictors of postpartum depressive symptomatology. An examination of differing trajectories from pregnancy to the postpartum period suggests that women with relatively few somatic complaints, low levels of perinatal stress, and satisfactory marital relations were less likely to exhibit mental health problems during pregnancy and postpartum. Women who were not depressed prenatally but reported postpartum depressive symptomatology exhibited several predisposing risk factors during pregnancy: many somatic complaints, high perinatal anxiety, and premigration stress. Women who were depressed during pregnancy but not postpartum reported improved physical function after childbirth. The implications of these findings for screening childbearing immigrant women are discussed. Correspondence: Dr. Phyllis Zelkowitz, Institute of Community and Family Psychiatry, Sir Mortimer B.

A follow-up study of postpartum depressed women: recurrent maternal depressive symptoms and child behavior after four years

Summary Objective: To investigate the prevalence of depressive symptoms and self reported health of women who have shown previous postpartum depressive symptoms. To examine the behavior of four-year-old children born to mothers affected by postpartum depression. Methods: Longitudinal study. The index group (n = 251) constituted of all women with postpartum depressive symptoms on the Edinburgh Postnatal Depression Scale (EPDS), in a population-based study made in the late 1990s. The control group (n = 502) consisted of women without postpartum depressive symptoms on the EPDS at the same occasion. Approximately four years after delivery these women were asked to answer a short questionnaire on general health, the EPDS, and also to assess their child’s behavior with the Richman Pre-School Behaviour Checklist. Results: Women with a history of postpartum depressive symptoms were approximately 6 times more likely to have recurrent depressive symptoms (OR = 5.82, 95% CI: 3.79–8.93), compared to those without postpartum depressive symptoms, and they were also more likely to experience physical and mental illness. Although postpartum depressive symptoms in the mothers were involved in explaining the likelihood of behavioral problems in their four-year-old children, mothers with current depressive symptoms were the most likely to have a child with behavioral problems (OR = 4.71, 95% CI: 1.88–11.78). Conclusion: Postpartum depressive illness constitutes a risk for future illness as well as maternal perceived behavioral problems in offspring. In order to diminish long-term adverse consequences for the mother and the child there is a great need to recognize and treat women with postpartum depressive symptoms as early as possible.     

Modifiable factors associated with changes in postpartum depressive symptoms

Up to 50% of mothers report postpartum depressive symptoms yet providers do a poor job predicting and preventing their occurrence. Our goal was to identify modifiable factors (situational triggers and buffers) associated with postpartum depressive symptoms. Observational prospective cohort telephone study of 563 mothers interviewed at 2 weeks and 6 months postpartum. Mothers reported on demographic factors, physical and emotional symptoms, daily function, infant behaviors, social support, and skills in managing infant and household. Mothers were categorized into four groups based on the presence of depressive symptoms at 2 weeks and at 6 months postpartum: never, always, late onset, and remission groups. Fifty-two percent did not have depressive symptoms at 2 weeks or at 6 months (never group), 14% had symptoms at both time points (always group), 10% had late onset, and 24% had early onset of symptoms with remission. As compared with women in the never group, women in the always and late onset groups had high-risk characteristics (e.g., past history of depression), more situational triggers (e.g., physical symptoms), and less robust social and personal buffers (i.e., social support and self-efficacy). As compared with the never group, mothers in the remission group had more situational triggers and fewer buffers initially. Changes in situational triggers and buffers were different for the four groups and were correlated with group membership. Situational triggers such as physical symptoms and infant colic, and low levels of social support and self-efficacy in managing situational demands are associated with postpartum depressive symptoms. Further research is needed to investigate whether providing education about the physical consequences of childbirth, providing social support, and teaching skills to enhance self-efficacy will reduce the incidence of postpartum symptoms of depression.     

Attachment disorganization moderates the effect of maternal postnatal depressive symptoms on infant autonomic functioning

We examined associations of disorganized attachment and maternal depressive symptoms with infant autonomic functioning in 450 infant‐mother dyads enrolled in the Generation R study. Maternal depressive symptoms were measured 2 months postpartum with the Brief Symptom Inventory. At 14 months, we assessed infant attachment with a slightly shortened Strange Situation and measured infant resting heart rate. Respiratory sinus arrhythmia (RSA) was calculated using spectral analysis. Higher levels of maternal postnatal depressive symptoms predicted lower resting RSA in disorganized infants (B = ?0.31, SE = 0.15, p = .04, R² = .05) but not in nondisorganized infants (B = 0.05, SE = 0.06, p = .36). This effect was buffered in disorganized infants with a secondary secure attachment classification. Disorganized infants were more vulnerable to the effect of maternal postnatal depressive symptoms on the physiological stress systems.     

Hair cortisol in pregnancy interacts with maternal depressive symptoms to predict maternal disrupted interaction with her infant at 4 months

Disrupted maternal interaction in early infancy is associated with maladaptive child outcomes. Thus, identifying early risk factors for disrupted interaction is an important challenge. Research suggests that maternal depressive symptoms and maternal cortisol dysregulation are associated with disrupted maternal interaction, but both factors have rarely been considered together as independent or interactive predictors of disrupted interaction. In a sample of 51 women, hair cortisol concentrations (HCC) and depressive symptoms were assessed during pregnancy, and depressive symptoms were assessed again at 4-month postpartum. Maternal disrupted interaction was assessed during the Still-Face Paradigm at 4 months. Results indicated that HCC and depressive symptoms interacted to predict both maternal withdrawing and inappropriate/intrusive interaction. Withdrawing interaction was associated with high levels of HCC in pregnancy in the context of high depressive symptoms at 4 months; inappropriate/intrusive interaction was associated with high levels of HCC in the context of low depressive symptoms. Thus, high HCC potentiated both forms of disrupted interaction. Results raised questions about the meaning of very low reported depressive symptoms, and underscored the importance of chronic stress physiology and maternal depressed mood as risk factors for distinct forms of maternal disrupted interaction, both of which are deleterious for infant development.     

Prenatal health behaviors and postpartum depression: is there an association?

Postpartum depression is a prevalent mental disorder; however, scarce research has examined its association with prenatal health behaviors. This study investigated the associations of cigarette smoking, caffeine intake, and vitamin intake during pregnancy with postpartum depressive symptoms at 8 weeks after childbirth. Using a prospective cohort study design, participants were recruited from the postpartum floor at a hospital for women and newborns located in a northeastern city, from 2005 through 2008. Eligible women who were at least 18 years old and spoke English were interviewed in person while hospitalized for childbirth (N = 662). A follow-up home interview was conducted at 8 weeks postpartum with a 79% response rate (N = 526). Hierarchical regression analyses showed that smoking cigarettes anytime during pregnancy and not taking prenatal vitamins in the first trimester were significantly associated with worse depressive symptoms (Edinburgh Postnatal Depression Scale). Moreover, having a colicky infant, an infant that refuses feedings, being stressed out by parental responsibility, and having difficulty balancing responsibilities were stressors associated with worse depressive symptoms. Primary health care providers should consider evaluating women for risk of postpartum depression during their first prenatal visit, identifying prenatal health behaviors such as smoking and taking prenatal vitamins.     

Parity mediates the association between infant feeding method and maternal depressive symptoms in the postpartum

Summary Maternal depression is the most common complication of the postpartum, having devastating and long lasting effects on mother and infant. Lactation is associated with attenuated stress responses, especially that of cortisol, and the lactogenic hormones, oxytocin and prolactin, are associated with anti-depressant and anxiolytic effects. These associations suggest that breast-feeding may decrease maternal depressive symptoms, yet empirical results have been conflicting. Recent findings have indicated that parity may mediate the association between breast-feeding and stress response. Because a decreased stress response is associated with a decreased risk for depression, parity may also mediate the association between infant feeding method and depressive symptoms. Specifically, the benefits of breast-feeding may appear in multiparous but not primiparous mothers. In the present study, data drawn from a national sample of primiparous and multiparous mothers were examined for possible associations between infant feeding method and depressive symptoms, as assessed by the Center for Epidemiological Survey-Depression scale (CES-D). After controlling for several possible confounding variables, breast-feeding by multiparas was associated with significantly decreased odds of having depression compared with bottle-feeders (OR = 0.41, CI 0.19–0.87, p = 0.02); however, no risk reduction from breast-feeding was evident among primiparas. The results support a parity-mediated association between lactation and maternal depressive symptoms. The results provide a reason for earlier conflicting findings, present new research avenues, and suggest possible clinical approaches.

Maternal depressive symptoms in the postnatal period are associated with long-term impairment of mother–child bonding

Summary Background: Postnatal Depression has demonstrated long-term consequences on child cognitive and emotional development, however, the link between maternal and child pathology has not been clearly identified. Objective: This study examined whether maternal bonding to the infant and young child is impaired by maternal depressive symptoms. Methods: 101 mothers of newborn infants were recruited from local obstetric units and examined for psychopathology using Symptom Checklist, the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Bonding Questionnaire at two weeks, six weeks, four months and fourteen months postpartum. Results: Maternal depressive symptoms at 2 weeks, 6 weeks and four months postnatally but not at fourteen months of infant’s age were found to be strongly associated with lower quality of maternal bonding to the infant and child from two weeks until fourteen months of postnatal age. Even mild and unrecognized maternal depressive symptoms had a significant impact on maternal bonding, if they occurred during the first four months of life. Conclusions: This gives reason for increased concern for mother–infant dyads in the first few months after birth that could be regarded as a highly sensitive period for the development of the mother–child relationship. The findings warrant further studies and inspire the development of preventive programs focussing on infant and early childhood mental health by emphasizing protection and support during the first critical months.     

Maternal distress across the postnatal period is associated with infant secretory immunoglobulin A

Employing a longitudinal design, relationships between maternal distress (i.e., perceived stress, negative affect, depressive symptomology), and infant secretory immunoglobulin A (sIgA) across the peripartum period were examined in 51 mother–infant dyads. Indices of maternal distress were assessed at four time periods: third trimester of pregnancy and 1, 3, and 6 months postpartum. Infant saliva samples were collected at each of the three time points in the postpartum period to assess sIgA levels. No relationships were found between prenatal maternal distress and infant sIgA. Results indicated that during the postnatal period, higher concurrent maternal distress was associated with reduced infant sIgA. Maternal distress did not prospectively predict infant sIgA. These findings advance our understanding of the social-context of infant development, highlighting the significance of maternal regulation of infant immunity.     

Serum leptin level measured 48 h after delivery is associated with development of postpartum depressive symptoms: a 3-month follow-up study

The aim of this study was to assess the possible relationship between leptin status and postpartum depressive symptoms using serum levels of leptin collected 24–48 h after delivery in a cohort Chinese sample. Women delivering a full-term, singleton, and live-born infant in the period from August 2013 to March 2014 were enrolled immediately postpartum. A blood sample was obtained 24–48 h after childbirth to test serum levels of leptin. Participation consisted of a visit in an obstetric unit at 3 months after delivery. The Edinburgh Postnatal Depression Scale (EPDS), completed at 3 months postpartum, was used to classify each woman’s depression symptom severity. Demographic, obstetric, behavioral risk, mental health, and psychosocial factors were considered. Multiple logistic regression analyses were used to identify risk factors most predictive of postpartum depressive symptoms. During the study period, 407 individuals were included and completed follow-up. At 3 months, according to EPDS score, 53 women (13.0 %) were considered as postpartum depressive symptoms. Serum leptin levels in women with PPD were significantly greater than those in women without depressive symptoms (36.5 [IQR, 25.5–50.4] vs. 14.5 [IQR, 9.4–22.4]?ng/ml, P?<?0.0001). Based on the ROC curve, the optimal cutoff value of serum leptin levels as an indicator for predicting of depressive symptoms was projected to be 24.3 ng/mL, which yielded a sensitivity of 88.7 % and a specificity of 73.4 %, with the area under the curve at 0.867 (95 % CI, 0.817–0.916). In multivariate analysis, there was an increased risk of depressive symptoms associated with leptin levels ≥24.3 ng/ml (OR 8.234; 95 % CI, 3.572–15.876; P?<?0.0001) after adjusting for possible confounders. Elevated serum leptin levels at delivery could eventually serve as a biological marker for the prediction of depressive symptoms. These associations were independent of other possible variables.     

Neuroendocrine and immune markers of maternal stress during pregnancy and infant cognitive development

Antenatal exposure to maternal stress is a factor that may impact on offspring cognitive development. While some evidence exists of an association between maternal antenatal depressive or anxiety symptoms and infants' cognitive outcomes, less is known about the role of biological indices of maternal antenatal stress in relation to infant cognitive development. The current study investigated the association between maternal depressive and anxiety symptoms, stress and inflammatory markers during pregnancy and infant's cognitive development in a sample of 104 healthy pregnant women (mean gestational age = 34.76; SD = 1.12) and their 12-week-old infants (mean postnatal weeks = 11.96; SD = 1.85). Maternal depressive and anxiety symptoms were evaluated during pregnancy, alongside measurements of serum Interleukin-6 (IL-6), C-Reactive Protein (CRP), salivary cortisol, and alpha amylase (sAA) concentrations. Infant cognitive development, maternal caregiving and concurrent anxiety or depressive symptoms were assessed 12 weeks after delivery. Hierarchical linear regressions indicated that higher maternal diurnal cortisol and CRP levels were independently associated with lower infant cognitive development scores, while adjusting for infant gender and gestational age, maternal IQ, caregiving, depressive, or anxiety symptoms. Though correlational, findings seem suggestive of a role for variation in maternal biological stress signals during pregnancy in influencing infants' early cognitive development.     

Maternal depression from pregnancy to 4 years postpartum and emotional/behavioural difficulties in children: results from a prospective pregnancy cohort study

Considerable attention has been focused on women’s mental health in the perinatal period and the subsequent impacts on children. Comparatively, we know much less about maternal depression at later time points and the potential implications for child mental health. The objective of this paper was to explore the association between maternal depression and child emotional/behavioural difficulties at 4 years postpartum, taking into account earlier episodes of perinatal depression. The Maternal Health Study is a prospective cohort study of 1,507 nulliparous women. Maternal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS) in early pregnancy and at 3, 6 and 12 months postpartum and again at 4 years postpartum. Maternal depressive symptoms at 4 years postpartum were associated with significantly increased odds of child emotional/behavioural difficulties (odds ratio (OR)?=?3.46, 95 % confidence interval (CI)?=?2.21–5.43). This remained significant after adjusting for earlier episodes of perinatal depression and socio-demographic characteristics (OR?=?2.07, 95 % CI?=?1.18–3.63). We also observed a robust association between child difficulties at age 4 and measures of socio-economic disadvantage. Our findings suggest a pressing need to rethink current paradigms of maternal health surveillance and extend mental health surveillance and support to at least 4 years postpartum.     

Comparing the effectiveness of home visiting paraprofessionals and mental health professionals delivering a postpartum depression preventive intervention: a cluster-randomized non-inferiority clinical trial

To determine whether pregnant women receiving the Mothers and Babies group–based intervention exhibited greater depressive symptom reductions and fewer new cases of major depression than women receiving usual community-based services, and to examine whether groups run by paraprofessional home visitors and mental health professionals yielded similar depressive symptom reductions and prevention of major depression. Using a cluster-randomized design, 37 home visiting programs were randomized to usual home visiting, Mothers and Babies delivered via home visiting paraprofessionals, or Mothers and Babies delivered via mental health professionals. Baseline assessments were conducted prenatally with follow-up extending to 24 weeks postpartum. Eligibility criteria were ≥ 16 years old, ≤ 33 gestation upon referral, and Spanish/English speaking. Depressive symptoms at 24 weeks postpartum was the primary outcome. Eight hundred seventy-four women were enrolled. Neither intervention arm was superior to usual care in decreasing depressive symptoms across the sample (p = 0.401 home visiting paraprofessional vs. control; p = 0.430 mental health professional vs. control). Post hoc analyses suggest a positive intervention effect for women exhibiting mild depressive symptoms at baseline. We have evidence of non-inferiority, as the model-estimated mean difference in depressive symptoms between intervention arms (0.01 points, 95% CI: −0.79, 0.78) did not surpass our pre-specified margin of non-inferiority of two points. Although we did not find statistically significant differences between intervention and control arms, non-inferiority analyses found paraprofessional home visitors generated similar reductions in depressive symptoms as mental health professionals. Additionally, Mothers and Babies appears to reduce depressive symptoms among women with mild depressive symptoms when delivered by mental health professionals. This trial is registered on ClinicalTrials.gov (initial post: December 1, 2016; identifier: NCT02979444).

     

Influence of depressive symptomatology on maternal health service utilization and general health

Summary Background: While postpartum depression is a well-established affective condition, information about its influence on health service utilization is scant. The objective of this study was to examine the influence of maternal mood on health service utilization and general health within the first 2 months postpartum.Methods: As part of a population-based postpartum depression study, a cohort of 594 women from British Columbia completed postal questionnaires at 1, 4, and 8 weeks postpartum.Results: Women with depressive symptomatology had a significantly higher number of contacts with a health professional than those with non-depressive symptomatology. Furthermore, over 50% of high utilizers of family physician and public health nursing services in the first month postpartum exhibited depressive symptomatology. Women with depressive symptomatology were also significantly more likely to have lower scores on the SF-36 and to indicate the care they received from family physicians to be unhelpful.Conclusion: Health professionals who discover a woman frequently using health services should closely examine the motivation for the visits and consider screening for postpartum depression. Future research should examine whether screening women with high utilization patterns reduces unnecessary health care visits and facilitates early diagnosis and treatment of postpartum depression.     

Depressive symptoms in early pregnancy, two months and one year postpartum-prevalence and psychosocial risk factors in a national Swedish sample

Summary Background: Depression and other psychiatric disorders during pregnancy and postpartum is an important health problem, especially if the symptoms are recurrent or sustained.Methods: All Swedish speaking women attending their first antenatal care visit during three predestined weeks were invited to participate. Depressive symptoms were evaluated using the Edinburgh Postnatal Depression Scale (EPDS) in early pregnancy, two months and one year postpartum.Results: In all, 2430 women completed three questionnaires. A dose-effect relation was found between the numbers of stressful life events experienced in the year prior to pregnancy and mean EPDS score in pregnancy. The prevalence of recurrent or sustained depressive symptoms (EPDS12 on all three evaluations) was 3% (79/2430). Three factors were associated with depressive symptoms, two or more stressful life events in the year prior to pregnancy, native language other than Swedish and unemployment.Conclusions: Apart from questions about psychiatric history, a psychosocial history in early pregnancy including stressful life events, native language and employment status could help the health professionals to identify women at risk for recurrent or sustained depression during pregnancy and the year after giving birth.     

The occurrence of panic and obsessive compulsive symptoms in women with postpartum dysphoria: a prospective study

Summary Objective: This study investigated the prevalence of panic and obsessive compulsive symptoms in a sample of postpartum women who endorsed high levels of dysphoria on a self-report depression measure. Method: A community-based sample of 788 postpartum women with self-reported depressive symptomatology completed an interview assessing major depression, panic disorder, and obsessive compulsive disorder. Results: An estimated 11% of the sample reported difficulties with panic attacks, 8% reported difficulties with obsessions, and 9% reported difficulties with compulsions. The most common panic symptoms included heart palpitations, sweating, trembling, and parasthesis. The most common content areas of obsessive compulsive symptoms were concerns about imminent disaster, compulsive cleaning behavior, and compulsive checking behavior, which were often related to fears concerning the newborn child. Comorbid depression and panic disorder was diagnosed in 1% of this sample, and comorbid depression and obsessive compulsive disorder was diagnosed in 2.4% of this sample. Conclusion: Postpartum panic and obsessive compulsive symptoms are common experiences that should be considered in treatment planning for women reporting dysphoria after they give birth.     

Impact of postpartum depressive and anxiety symptoms on mothers’ emotional tie to their infants 2–3 months postpartum: a population-based study from rural Bangladesh

The purpose of this study was to investigate the impact of depressive and anxiety symptoms on maternal bonding to the infant 2–3 months postpartum and the influence of the mother’s bonding to the infant during pregnancy and to her own caregiver during her childhood on maternal bonding 2–3 months postpartum. This study originated from a community-based cohort study carried out in rural Bangladesh. Trained staff collected data and administrated the questionnaires during the third trimester of pregnancy, at childbirth and 2–3 months postpartum. Maternal depressive and anxiety symptoms were assessed with the Edinburgh Postnatal Depression Scale and the State Anxiety Inventory and the mother’s emotional bonding to the infant with the Postpartum Bonding Questionnaire. The results showed that 11% of the women reported depressive symptoms, 35% anxiety symptoms, 3.4% both depressive and anxiety symptoms and 51% neither depressive nor anxiety symptoms. Mothers with depressive symptoms were older, were poorer, fewer were literate, reported more intimate partner violence and showed lower emotional bonding to their infants 2–3 months postpartum compared to mentally well and anxious mothers. Approximately 11% of the mothers reported mild bonding disturbances and nearly one third of them showed depressive symptoms. Depressive symptoms and giving birth to a girl were negatively associated to a mother’s emotional bonding to her infant, while maternal anxiety symptoms and high bonding to the foetus during pregnancy were positively associated to the mother's emotional bonding to the infant 2–3 months postpartum.     

Cohort study of depressive moods in Thai women during late pregnancy and 6–8 weeks of postpartum using the Edinburgh Postnatal Depression Scale (EPDS)

Summary Objective: To identify depressive moods as measured by the Edinburgh Postnatal Depression Scale in late pregnancy and postpartum, explore associated factors and assess changes in depressive moods. Methods: A cohort study of 610 pregnant Thai women was conducted. The self-reporting EPDS was completed at 36–40 weeks and at 6–8 weeks postpartum. Result: The prevalence of depressive moods (scores of 10 or more on the EPDS) was 20.5% during pregnancy and 16.8% at postpartum. Factors related to depressive moods in late pregnancy included marital status, evidence of irritable moods before menstruation, and attitudes towards this pregnancy. Unmarried women, women having irritable moods before menstruation or women having negative attitudes towards this pregnancy had double risk. Related factors during the postpartum period included religion, evidence of irritable moods before menstruation, perception of pregnancy complications and attitudes towards this pregnancy (p < 0.01). Women who perceived of having complications during this pregnancy, those who had irritable moods before menstruation or had negative attitudes towards this pregnancy had also double risk. The depressive moods were significantly reduced postnatally. Conclusion: One-fifth of pregnant and postpartum women experienced depressive moods but the severity declined at postpartum.
