Postpartum depression has been described as a thief that steals motherhood. It can result in tragedy and sometimes in headline-gripping maternal suicide or infanticide. Because one of the highest priorities for nursing is to continually advance the knowledge that underlies nursing practice, it is essential that we understand what nurse researchers have done to advance the knowledge base of postpartum depression. This integrative review is a two-part series for MCN that summarizes 141 postpartum depression studies conducted by nurse researchers from around the globe, including United States, Australia, Canada, China (Hong Kong, Taiwan), Finland, Iceland, Sweden, Turkey, and Malaysia. Specific areas of postpartum depression to which nurse researchers have devoted their primary attention include epidemiology, risk factors, transcultural perspectives, instrument development, screening, interventions, and mother-infant interactions.
AIM: Prolonged depression during the post-partum period is associated with maternal and infant mortality and morbidity. Less attention has been given to factors that predict the persistence of depression beyond the first 3 months post-partum.
METHODS: From a longitudinal cohort of 2279 women who attended Mazandaran's primary health centres in 2009, 478 women with an Edinburgh Postnatal Depression Scale (EPDS) score of 12 or greater in the third trimester of pregnancy were recruited. Persistently depressed women (depressed at all three occasions: during pregnancy, and at 2 and 12 weeks post-partum) were compared with those without depression to determine demographic, cultural, obstetric and biopsychosocial predictors for persistence of depression. Data were analysed using chi-square test, t-test and logistic regression models.
RESULTS: The stability of depression was found in 193 (46.2 %) of 418 depressed cases who were followed up over the study period. Of those mothers who scored more than the threshold of 12 during the third trimester of pregnancy, 277 (66.3%) and 221 (52.9%) had high EPDS at 2 and 12 weeks post-partum. Psychological distress (based upon the General Health Questionnaire), low maternal parental self-efficacy (based upon the Parental Expectation Survey) and perceived social isolation (based upon the Network Orientation Scale) were independent predictors of persistent depression.
CONCLUSION: Fewer depressed mothers in this study were found to recover during the first 3 months after giving birth. Psychosocial factors predicted sustained depression from pregnancy to 3 months post-partum. The findings highlight the significance of support in enhancing maternal mental health.
BACKGROUND:
The prevalence of postpartum depression (PPD) is currently considered to be 10-15%. Most studies were performed with a brief unidimensional instruments (mostly the Edinburgh Postnatal Depression Scale-EPDS) with focus on depression and not on other symptoms and disorders. Most cited studies were conducted in Western economically developed countries.
METHODS:
We reviewed the literature on prevalence of postpartum depression and depressive symptoms in a wide range of countries.
RESULTS:
143 studies were identified reporting prevalence in 40 countries. It is demonstrated that there is a wide range of reported prevalence of PPD ranging from almost 0% to almost 60%. In some countries like Singapore, Malta, Malaysia, Austria and Denmark there are very few reports of PPD or postpartum depressive symptoms, whereas in other countries (e.g. Brazil, Guyana, Costa Rica, Italy, Chile, South Africa, Taiwan and Korea) reported postpartum depressive symptoms are very prevalent.
CONCLUSIONS:
We believe that the widely cited mean prevalence of PPD-10-15% is not representative of the actual global prevalence and magnitude of the problem, due to the wide range of reports. The variability in reported PPD might be due to cross-cultural variables, reporting style, differences in perception of mental health and its stigma, differences in socio-economic environments (e.g. poverty, levels of social support or its perception, nutrition, stress), and biological vulnerability factors. The elucidation of the underlying processes of this variability as well as the diversity of postpartum normal versus abnormal expressions of symptoms may contribute to better understanding of the diversified ante, peri- and postpartum phenomena.
Depression can occur due to common major life transitions, such as giving birth, menopause, retirement, empty-nest transition, and midlife crisis. Although some of these transitions are perceived as positive (e.g., giving birth), they may still lead to depression. We conducted a systematic literature review of the factors underlying the occurrence of depression following major life transition in some individuals. This review shows that major common life transitions can cause depression if they are sudden, major, and lead to loss (or change) of life roles (e.g., no longer doing motherly or fatherly chores after children leave family home). Accordingly, we provide a theoretical framework that explains depression caused by transitions in women. One of the most potential therapeutic methods of ameliorating depression associated with life transitions is either helping individuals accept their new roles (e.g., accepting new role as a mother to ameliorate postpartum depression symptoms) or providing them with novel life roles (e.g., volunteering after retirement or children leave family home) may help them overcome their illness.
Administration mode of patient-reported outcome measures (PROMs) may influence responses. We assessed if Patient Health Questionnaire-9 (PHQ-9), Edinburgh Postnatal Depression Scale (EPDS) and Hospital Anxiety and Depression Scale - Depression subscale (HADS-D) item responses and scores were associated with administration mode. We compared (1) self-administration versus interview-administration; within self-administration (2) research or medical setting versus private; and (3) pen-and-paper versus electronic; and within interview-administration (4) in-person versus phone. We analysed individual participant data meta-analysis datasets with item-level data for the PHQ-9 (N = 34,529), EPDS (N = 16,813), and HADS-D (N = 16,768). We used multiple indicator multiple cause models to assess differential item functioning (DIF) by administration mode. We found statistically significant DIF for most items on all measures due to large samples, but influence on total scores was negligible. In 10 comparisons conducted across the PHQ-9, EPDS, and HADS-D, Pearson's correlations and intraclass correlation coefficients between latent depression symptom scores from models that did or did not account for DIF were between 0.995 and 1.000. Total PHQ-9, EPDS, and HADS-D scores did not differ materially across administration modes. Researcher and clinicians who evaluate depression symptoms with these questionnaires can select administration methods based on patient preferences, feasibility, or cost.
Over recent years, researchers have found evidence which indicates that the prevalence of postpartum depressive symptoms crosses cultural boundaries and is reported to be at least as high in non-Western countries as in Western countries. However, qualitative studies about new mothers' experiences from non-Western countries, such as Bangladesh, are rare, particularly in rural areas. This study aims to describe the experiences and concerns of rural Bangladeshi mothers with postpartum depressive symptoms. Open narrative interviews were conducted with 21 mothers with depressive symptoms 2-3 months postpartum, consecutively selected from a longitudinal study about prevalence and risk factors of perinatal depressive symptoms. Inductive content analysis was used to analyse data and three themes emerged: family dynamics, living at the limits of survival, and role of the cultural context after childbirth. These themes were based on six categories and 15 subcategories. The findings show that troublesome family relationships, including intimate partner violence and violence in the family, influenced the mothers' mental well-being. They and their families lived at the limit of survival and the mothers expressed fear and worries about their insecure situation regarding economic difficulties and health problems. They felt sorry for being unable to give their infants a good start in life and sad because they could not always follow the traditional norms related to childbirth. Thus, it is important to focus on the depressive symptoms among new mothers and offer counselling to those showing depressive symptoms, as the cultural traditions do not always alleviate these symptoms in the changing Bangladeshi society today.
BACKGROUND: Postnatal depression can have serious consequences for both the mother and infant. However, epidemiological data required to implement appropriate early prevention are still lacking in Malaysia.
AIM: To investigate the prevalence of postnatal depression within six months postpartum and associated risk factors among women in Sabah, Malaysia.
METHODS: A prospective cohort study of 2072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36-38 weeks of gestation and followed up at 1, 3 and 6 months postpartum. The presence of depressive symptoms was assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale. Logistic regression analyses were performed to ascertain risk factors associated with postnatal depression.
FINDINGS: Overall, 14.3% of mothers (95% confidence interval (CI) 12.5-16.2%) had experienced depression within the first six months postpartum. Women depressed during pregnancy (odds ratio (OR) 3.71, 95% CI 2.46-5.60) and those with consistent worries about the newborn (OR 1.68, 95% CI 1.16-2.42) were more likely to suffer from depression after childbirth. Women whose husband assisted with infant care (OR 0.43, 95% CI 0.20-0.97) and mothers who were satisfied with their marital relationship (OR 0.27, 95% CI 0.09-0.81) appeared to incur a reduced risk of postnatal depression.
CONCLUSION: A substantial proportion of mothers suffered from postnatal depression in Sabah, Malaysia. Screening and intervention programmes targeting vulnerable subgroups of women during antenatal and early postpartum periods are recommended to deal with the problem.

This two-part series summarizes 141 postpartum depression studies that have been conducted by nurse researchers from around the globe. Studies contributing to the knowledge base of postpartum depression were conducted in the following nine countries: United States, Australia, Canada, China (Hong Kong, Taiwan), Finland, Iceland, Sweden, Turkey, and Malaysia. Part 1 of this series addressed the contributions of nurse researchers in the areas of epidemiology, risk factors, and transcultural perspectives related to postpartum depression. This article is Part 2, and it describes what nurse researchers have contributed to the following aspects of postpartum depression: instrumentation/screening, interventions, mother-infant interactions, family dynamics, breastfeeding, preterm births, biological factors, clinicians' knowledge, and mothers' use of health services.
BACKGROUND: Research on antepartum psychiatric morbidities investigating depressive and anxiety symptoms in expectant mothers and fathers is lacking in low- and middle-income countries. This study aimed to estimate the prevalence of antepartum depressive, anxiety and co-occurring significant symptoms and explore the associated factors in a cross-section of Malaysian expectant mothers and fathers.
METHODS: We used cross-sectional data from a prospective cohort study of 911 expectant mothers and 587 expectant fathers during their third trimester of pregnancy, from health clinics of two states in the east and west coasts of Malaysia. The validated Malay version of Edinburgh Postnatal Depression Scale and the anxiety sub-scale of Depression, Anxiety and Stress Scale were used to measure the depressive and anxiety symptoms. Multiple logistic regression analyses identified the determinants of antepartum depressive and anxiety symptoms (ADS and AAS).
RESULTS: Prevalence of ADS was 12.2% in expectant mothers and 8.4% in expectant fathers, while AAS was 28.8% in expectant mothers and 13.3% in expectant fathers, and co-occurring significant symptoms was 8.0% in expectant mothers and 4.0% in expectant fathers. Expectant mothers and fathers having perceived social/family support were less likely to suffer from ADS. Intimate partner violence, poor relationship with husbands, depression in earlier pregnancy and husband's depression in current pregnancy in expectant mothers, and living in rented house, sex preference for the unborn child, stressful life events and wife's depression in current pregnancy in expectant fathers were associated with a greater likelihood of ADS. The determinants for AAS were living in rented house and with parents/in-laws, poor relationship with husbands, restrictions during pregnancy and stressful life events for expectant mothers, and stressful life events and being unsupportive towards wives in household chores for expectant fathers.
CONCLUSION: Both ADS and AAS are prevalent in expectant mothers and fathers, and largely an undetected problem in Malaysia. Administration of couple-based screening and referral program during antenatal check-up should be universal practices to identify and treat the psychiatric morbidities.
