Is postpartum depression related to total weight gain during pregnancy and maternal anemia?

OBJECTIVE: This study aimed to investigate the effects of weight gain and maternal anemia on postpartum depression. METHODS: This is a prospective, single-center, case-control study. We recorded the demographic characteristics, blood ferritin level, and weight gain during the pregnancy. This study was planned between April 2023 and June 2023 in the Obstetrics and Gynecology Clinic of Ankara Etlik City Hospital. A total of 109 patients were enrolled in the study. Patients were assessed with the Edinburgh Postpartum Depression Scale. Weight gain, nutritional education, educational level, mode of delivery, and pregnancy history were asked in person. Ferritin levels at the onset of labor were determined to detect anemia. Twin births, births due to fetal anomalies or intrauterine stillbirths, patients with systemic infections, and patients diagnosed with a psychiatric disorder in the past 6 months whose records were not accessible were excluded from the study. RESULTS: Pregnancy weight gain and percentage of pregnancy weight gain were higher. Serum ferritin levels and nutritional education during pregnancy were lower in the postpartum depression group (p<0.001). These parameters with statistical significance were identified as risk factors in the regression analysis for postpartum depression (p<0.05). In receiver operating characteristics analysis, >15 kg for weight gain, >28.8 for percentage of weight gain in pregnancy, and <19 ng/dL for serum ferritin level were identified as cutoff values (p<0.001). CONCLUSION: Nutritional education and vitamin supplementation should be recommended to pregnant women during routine examinations.

Folic acid supplementation during pregnancy and postpartum depressive symptoms.

OBJECTIVE: To verify whether folic acid supplementation during pregnancy is associated with the occurrence of maternal depressive symptoms at three months postpartum, in the 2015 Pelotas Birth Cohort. METHODS: This study included 4,046 women, who were classified into three groups: did not use folic acid supplementation during pregnancy; used during only one trimester of pregnancy; and used for two or three trimesters. Depressive symptoms were assessed at three months postpartum using the Edinburgh Postnatal Depression Scale (EPDS), at cutoff points ≥ 10 (mild symptoms) and ≥ 13 (moderate to severe intensity). RESULTS: The overall prevalence of mild symptoms was of 20.2% (95%CI 19.0-21.5), and moderate and severe was 11% (95%CI 10.0-12.0). The prevalence of EPDS ≥ 10 was of 26.8% (95%CI 24.0-29.5) among women who did not use folic acid and 18.1% for both those who used it during one trimester of pregnancy (95%CI 16.1-20.1) and those who used it for two or three trimesters (95%CI 16.0-20.2). The prevalence of EPDS ≥ 13 was of 15.7% (95%CI 13.5-17.9) in those who did not use folic acid, 9.1% (95%CI 7.5-10.6) in those who used it for one trimester, and 9.4% (95%CI 7.8-11.0) in those who used it for two or three trimesters. In the adjusted analyses, there was no statistically significant association between the use of folic acid during pregnancy and the occurrence of depressive symptoms at three months postpartum. CONCLUSION: There was no association between folic acid supplementation during pregnancy and postpartum depression at three months.

Predictors of Postpartum Depression Among Women with Low Incomes in the United States.

PURPOSE: To evaluate the predictors of postpartum depression and to examine the effects of maternal racial identity on postpartum depression among women with low incomes in the United States. STUDY DESIGN AND METHODS: We conducted a secondary data analysis using baseline data from the Baby's First Years study, including postpartum women living below the federal poverty line who were recruited from four diverse communities in the United States. Postpartum depression symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Logistic regressions were performed to identify associations between pre-identified postpartum depression risk factors and postpartum depression among participants, followed by predictive margins analyses to elaborate on probability of postpartum depression across different racial identity groups in the sample. RESULTS: The sample included 1,051 postpartum women. Almost one-half of participants identified as Black (45.9%), followed by White (20.7%), American Indian (1.8%), and Asian (1.3%). Prevalence of postpartum depression in the sample was 24%. Financial insecurity and alcohol use were positively associated with postpartum depression, whereas level of education and reported physical health were negatively associated with postpartum depression. Mothers who identified as Black had an 8.3% higher probability of postpartum depression than that of White mothers in the sample. CLINICAL IMPLICATIONS: Nurses working with populations with low income should assess social determinants of health to provide holistic mental health care. Women with low incomes should be referred to resources which account for their financial burden. Racial disparities exist in perinatal care, and birth and postpartum mental health outcomes. It is crucial to address the systemic racism faced by Black mothers experiencing postpartum depression.

Postpartum dietary intake, depression and the concentration of docosahexaenoic acid in mature breast milk in Wuhan, China.

Background: Docosahexaenoic acid (DHA, C22:6) is an important fatty acid in breast milk and is essential for infantile growth and cognitive development. However, the factors that affect the DHA concentration in breast milk have not been completely clarified. Objective: This study aimed to characterize the composition of breast milk fatty acids and to identify maternal factors associated with breast milk DHA concentration in postpartum women in Wuhan, China. Methods: In this cross-sectional study, we analyzed milk fatty acids in 115 lactating women at 30-120 days postpartum using GC-MS. Maternal sociodemographic, health and other information were collected using a self-reported questionnaire. Maternal dietary intake information was collected through a 24-hour dietary recall method. Postpartum depression status was identified using the Edinburgh Postnatal Depression Scale (EPDS). Results: The mean DHA proportion in breast milk was 0.49%. The multivariate regression model showed that the milk DHA proportion was positively associated with maternal aquatic product intake (ß = 0.183, 95%CI: 0.052, 0.314) and DHA supplement use (ß = 0.146, 95%CI: 0.108, 0.185), and negatively associated with postpartum depression status (ß = -0.122, 95%CI: -0.243, -0.002) after adjustment for several maternal and infant factors. Conclusion: Increasing maternal aquatic product intake and DHA supplement use and improving postpartum depression status may increase DHA concentration in breast milk in lactating women.

Gestational hemodilution as a putative risk factor for postpartum depression: A large-scale nationwide longitudinal cohort study.

BACKGROUND: While anemia during pregnancy has been linked to increased postpartum depression (PPD) risk, longitudinal studies on the association between gestational hemodilution, represented by decreased hematocrit (Hct) during the transition from the 1st to 2nd trimester, and PPD risk, are scarce. The current study aimed to investigate this association in a nationwide cohort over the perinatal period. METHODS: This retrospective cohort study included 104,715 women who gave birth between January 2008 and December 2015. The cohort was followed up for new-onset PPD during the year post birth and gestational hemodilution was assessed by the change in Hct levels (Δ: 2nd-1st trimester). The cohort was divided into three hemodilution groupings: maximal and minimal 10 % of mothers and intermediate 80 %. Multivariable regression analyses were performed to estimate the association between gestational hemodilution and PPD, adjusting for confounders. RESULTS: Among the full cohort, 2.2 % (n = 2263) met the definition of new-onset PPD. Mothers with greater hemodilution had higher rates of PPD: 2.7 % (n = 269) in the maximal hemodilution group, 2.1 % (n = 1783) in the intermediate and 1.9 % (n = 211) in the minimal hemodilution group (p < 0.001). The maximal hemodilution group had higher rates of pre-gestational psychiatric disorders (p < 0.001) and higher adjusted risk for PPD [OR = 1.18, 95 % CI (1.04, 1.35)]. LIMITATIONS: Data on iron levels and supplementation were unavailable, thus it could not be adjusted for in the analysis. CONCLUSIONS: Women in the top 10th percentile of gestational hemodilution may be at risk for PPD, justifying monitoring of gestational Hct as a biomarker for PPD.

Early pregnancy essential and non-essential metal mixtures and maternal antepartum and postpartum depressive symptoms.

BACKGROUND: Mood disorders are common during and after pregnancy, and environmental metals may contribute to increased risk. Antepartum metal exposures have not been well characterized in relation to maternal depression. We evaluated the extent to which early pregnancy erythrocyte concentrations of essential and non-essential metals were prospectively associated with antepartum and postpartum depressive symptoms. METHODS: Participants were 1226 women in Project Viva, a longitudinal cohort recruited during pregnancy (1999-2002). We measured concentrations of 11 metals in maternal first trimester erythrocytes (arsenic, barium, cadmium, cesium, copper, mercury, magnesium, manganese, lead, selenium, zinc). Using the Edinburgh Postnatal Depression Scale (EPDS), we assessed elevated depressive symptoms (≥13; 0-30 scale) at mid-pregnancy and at 6 and 12 months postpartum. We applied latent class mixed modeling to identify symptom trajectories. Adjusting for maternal sociodemographics and co-exposures, we examined associations between the metal mixture and depressive symptoms using logistic (for EPDS≥13)/multinomial (for symptom trajectories) regression and quantile g-computation. RESULTS: In this cohort of moderately high socioeconomic status participants (e.g., 72 % college graduate), low-level metal concentrations were weakly to moderately correlated (Spearman: -0.24 to 0.59); the prevalence of depressive symptoms ranged from 9 % (mid-pregnancy) to 6 % (12 months postpartum); and three trajectories (stable low; elevated mid-pregnancy, then decreasing; moderate mid-pregnancy, then increasing) best fit the EPDS data. The early pregnancy erythrocyte metal mixture was not associated with maternal depressive symptoms in logistic, multinomial, or mixture models. For individual metals, most confidence intervals (CI) included the null. There was weak evidence that arsenic, lead, and selenium were moderately associated with elevated odds of depressive symptoms and/or trajectories. However, the odds ratios (95 % CI) per doubling of these three metals were imprecise [e.g., arsenic: 1.13 (0.94, 1.40) for EPDS≥13 at six months postpartum; lead: 1.19 (0.80, 1.77) for EPDS≥13 at mid-pregnancy; selenium: 2.35 (0.84, 6.57) for elevated mid-pregnancy, then decreasing versus stable low trajectory]. DISCUSSION: We did not observe strong, consistent evidence of associations between early pregnancy erythrocyte metal concentrations and subsequent maternal antepartum and postpartum depressive symptoms.

Trait mindfulness facets as a protective factor for the development of postpartum depressive symptoms.

BACKGROUND: Postpartum depression has a prevalence rate of up to 17%. As there are many negative consequences of postpartum depressive symptoms, it is important to examine possible protective factors, such as trait mindfulness. Since postpartum depressive symptoms are variable over time between and within individuals, this study focused on the possible association between facets of trait mindfulness and trajectories of postpartum depressive symptoms throughout the first postpartum year. METHODS: A subsample of 713 women that participated in the HAPPY study completed the Three Facet Mindfulness Questionnaire-Short Form at 22 weeks of pregnancy and the Edinburgh Postnatal Depression Scale (EPDS) at six weeks, four months, eight months, and twelve months postpartum. Possible different EPDS trajectories were obtained by means of growth mixture modeling. RESULTS: Two EPDS trajectories (classes) were found: a low stable symptom class (N = 647, 90.7%) and an increasing-decreasing symptom class (N = 66, 9.3%). Women in the low stable class showed higher 'acting with awareness' and 'non-judging' scores. A higher score on the 'non-judging' facet of trait mindfulness was associated with a higher likelihood of belonging to the low stable class (OR = 0.79, 95% CI [0.72, 0.87], p < 0.001), adjusted for confounders and the other mindfulness facets. CONCLUSIONS: The non-judging facet of trait mindfulness was associated with low stable levels of depressive symptoms during the first postpartum year. Mindfulness-based programs, focusing on enhancing non-judging may be of benefit for pregnant women to possibly decrease the risk of developing postpartum depressive symptoms after childbirth.

Predisposition of Early Maladaptive Schemas and Postpartum Depression during COVID-19 Crisis: Mediation of Mindfulness.

BACKGROUND: Past studies provide crucial evidence that pregnancy and childbirth increase the risk of emotional vulnerability and instability. Current research intends to explore the role of early maladaptive schemas and mindfulness as determinants of postpartum depression for expecting mothers during COVID-19 pandemic. METHOD: The data was collected from 170 expecting mothers who conceived and gave birth during the COVID-19 pandemic. Edinburgh postnatal depression scale, the young schema questionnaire-SF 75 items, and the Kentucky inventory for mindfulness scale were administered. RESULTS: Results discovered that mindfulness partially mediated the relationship between three kinds of early maladaptive schemas and postpartum depression. CONCLUSION: Mindfulness-based control techniques can be considered to buffer the impact of the early maladaptive schemas on postpartum depression, for mothers who give birth during any challenging time.

Patterns of peripartum depression screening and detection in a large, multi-site, integrated healthcare system.

The purpose of this study was to examine peripartum depression (PD) screening patterns within and across the prenatal and postpartum periods and assess the incidence of new positive screens during standard screening protocol timepoints to inform practice, particularly when limited screenings can be conducted.This is a retrospective observational study of women screened for PD through a large, integrated health system using the Edinburgh Postnatal Depression Scale (EPDS) within their obstetrics and pediatric practices. Pregnancies with an EPDS score for at least one obstetric and one pediatric appointment between November 2016 and October 2019 were included (n = 3240). The data were analyzed using chi-squared test, Student's t-test, and binary logistic regression analyses. An EPDS score of 10 or higher was considered a positive screen.The positive screening rate for this cohort was 18.5%, with a prenatal positive rate of 9.9% and a postpartum positive rate of 8.6%. Single relationship status showed a higher rate of PD overall. Two thirds of women were not screened until their third trimester, resulting in delayed detection for an estimated 28% of women who ultimately screened positive. Few new positive screens (1.3%) were detected after 9 weeks postpartum in women who had completed all recommended prior screens.Obstetric providers should screen for PD as early in pregnancy as possible and continue to screen as often as feasible regardless of previous negative EPDS scores. Prioritizing screening more often in pregnancy and before 9 weeks postpartum is optimal to avoid delays in detection and intervention.

Evaluation of women's sexual quality of life, depression, and sexual functions in the pregnancy and postpartum periods: A multi-centered study.

AIM: This multi-centered, longitudinal, and prospective study aims to identify women's sexual functions, sexual quality of life, and depression and their relationships with each other in the pregnancy and postpartum periods. METHODS: The participating pregnant women (n = 113) were interviewed six times: once in each trimester, and once in the eighth week third month, and sixth month postpartum. This study was conducted in three regions of Turkey including Marmara, Mediterranean, and Central Anatolia regions. Data were collected through the "Socio-demographic Form," "Female Sexual Function Index (FSFI)," Sexual Quality of Life-Female Questionnaire (SQLQ-F), and "Center for Epidemiologic Studies-Depression Scale (CES-D)." While the first interviews were administered face to face, successive ones were administered via phone. RESULTS: The sexual dysfunction rates of the participants were found to be high in the pregnancy and postpartum periods, and their sexual quality of life, which decreased as the pregnancy months progressed, was found to increase significantly with the progress in the postpartum period. The sexual dysfunction increased and sexual quality of life decreased significantly with the increase in depression symptoms in the pregnancy and postpartum periods. When the depressive symptoms decreased especially in the sixth month postpartum, sexual quality of life was also found to increase. CONCLUSIONS: As a result, in the pregnancy and postpartum periods, it is highly important to provide women with diagnosis through a holistic approach by creating available environments to assess their psychological health and sexual functions and refer them to the related physicians when necessary.

The association between intravenous iron for antenatal anemia and postnatal depression: a retrospective cohort study.

PURPOSE: Determine if intravenous iron for antenatal anemia is associated with reduced incidence of postnatal depression (PND) within 12 months. METHODS: This retrospective cohort study included adult women with antenatal anemia (hemoglobin value of < 11.0 g/dL within 3 months before delivery). PND was defined as Edinburgh Postnatal Depression Scale (EPDS) or Patient Health Questionnaire-9 (PHQ-9) ≥ 10. Data on intravenous iron, lowest hemoglobin concentration, EPDS and PHQ-9 scores, insurance status, history of anxiety, depression, chronic pain, and substance use, obstetric complications, labor analgesia, and mode of delivery were obtained. Standardized mean difference (SMD) was estimated and multivariable logistic regression models were constructed with adjustment for potential confounders with absolute SMD of ≥ 0.1. RESULTS: Data from 3988 women were analyzed. The 368 (9.2%) women who received intravenous iron therapy had lower antenatal hemoglobin levels, were more likely to be African American or single/widowed women, and more commonly had  Medicaid coverage, repeat cesarean delivery, and history of depression compared to those who did not receive intravenous iron therapy. Unadjusted analysis showed women who received intravenous iron had higher incidence of PND (18.5%) than those who did not (13.4%) (p = 0.008). Multivariable analysis showed no significant association between intravenous iron and PND incidence (aOR 1.21, 95%CI 0.89-1.63, p = 0.232), although history of depression (aOR 2.42, 95%CI 1.91-3.08, p < 0.001), higher gravidity (aOR 1.09, 95%CI 1.02-1.17, p = 0.016), and Medicaid insurance (aOR 1.44, 95%CI 1.16-1.80, p = 0.001) were independently associated with PND. CONCLUSION: Intravenous iron for antenatal anemia was not associated with significant change in the incidence of PND.

Acceptance Mindfulness-Trait as a Protective Factor for Post-Natal Depression: A Preliminary Research.

(1) Background: the prevalence of postnatal depression (PND) reaches up to 20%. PND could be based on the interaction between a psychological vulnerability and chronic stress that pregnancy would activate. Vulnerability factors reflect a psychological profile mirroring mindfulness-trait (MT). A high level of MT is associated with an efficient regulation of both physiological and psychological stress, especially negative moods. Interestingly, mindfulness level can be improved by program based on mindfulness meditation. We hypothesize that MT is a protective factor for PND. We also postulate that negative moods increase during the pregnancy for women who develop a PND after delivery (2) Methods: we conducted a multicentric prospective longitudinal study including 85 women during their first trimester of their pregnancy and 72 from the childbirth to the baby's first birthday". At the inclusion, presence and acceptance of MT and various variables of personality and of psychological functioning were assessed. Mood evolution was monitored each month during the pregnancy and a delivery trauma risk was evaluated after delivery. PND detection was carried out at 48 h, 2, 6 and 12 months after the delivery with the Edinburgh Postnatal Depression Scale with a screening cut-off >11. (3) Results: high-acceptance MT is a protective factor for PND (OR: 0.79). Women without PND displayed less negative mood during pregnancy (p < 0.05 for Anxiety, Confusion and Anger). (4) Conclusions: these results suggest the value of deploying programs to enhance the level of mindfulness, especially in its acceptance dimension, before, during and after pregnancy, to reduce the risk of PND.

Postpartum Depressive Symptoms and Experiences During COVID-19.

PURPOSE: To identify postpartum depression risk and describe experiences of women in the first 6 weeks after giving birth during the COVID-19 pandemic. STUDY DESIGN AND METHODS: Using a convergent mixed-methods approach, we recruited a convenience sample of women living in the United States who gave birth March 1, 2020 or later from social media Web sites. Participants completed the Postpartum Depression Screening Scale-Short Form and provided written answers to open-ended questions regarding their experiences at home with their new infant. RESULTS: Our 262 participants were on average 32.6 years of age, the majority were White (82%), married or partnered (91.9%), and college educated (87.4%). Mean postpartum depression score was 17.7 (SD = 5.9) with 75% scoring ≥14, indicating significant postpartum depressive symptoms. Qualitative content analysis revealed five themes: Isolation and seclusion continue; Fear, anxiety, and stress filled the days; Grieving the loss of normal: It's just so sad; Complicated by postpartum depression: A dark time; and There is a silver lining. Quantitative and qualitative findings provided a holistic view of women's depressive symptoms and experiences at home with their infants during the COVID-19 pandemic. CLINICAL IMPLICATIONS: Although policies that reduce risk of COVID-19 exposure and infection for patients and the health care team must continue to be implemented, the adverse effects of depressive symptoms on maternal-infant wellbeing within the context of increased isolation due to the pandemic need to be kept at the forefront. Nurses need to be aware of the consequences of women sheltering in place and social distancing on maternal-infant outcomes, particularly on depression and likelihood of breastfeeding.

Postpartum depression and suicide in Iran.

In Iran, postpartum depression is one of the common emotional symptoms which affects approximately 25% of the women who experienced childbirth. Iranian Forensic Medicine Organization (IFMO) and its branches across the country are the comprehensive sources of collecting data related to suicide deaths. In the data collecting form of suicide, there is not any item about the pregnancy of women at the time of suicide, having childbirth during the previous six weeks, and the time interval between delivery and suicide. It is suggested that, in addition to modifying the suicide registration forms by the IFMO, attention should be given to developing a mechanism that gives forensic physicians access to medical records information in the integrated health system as well as hospital information system.

Perinatal depression.

PURPOSE OF REVIEW: Perinatal depression is a common and debilitating complication of pregnancy and childbirth. Recent studies have elucidated relationships between acute birth events on depression risk, and novel treatments for postpartum depression have been discovered and approved. This article reviews current understandings about birth events on depression, new screening standards, and novel treatments for postpartum depression. RECENT FINDINGS: Pain, analgesia, and depression are complex traits that are inter-related during and after pregnancy. Certain individuals may benefit more than others from addressing pain and suffering around childbirth. Exposures to general anesthesia or postdural puncture headache are associated with postpartum depression symptoms, although a causal relationship is unlikely. Brexanolone, ketamine and its related compounds, and nonpharmacologic options offer new or alternative therapies for depression, although safety information for some of these treatments in pregnancy and lactation are needed. Maternal health bundles call for close attention to perinatal mental health screening with validated instruments, and for timely treatment referrals in the 'fourth trimester'. SUMMARY: Clinical monitoring and timely treatment of depression in the perinatal and postpartum periods is critical for maternal postpartum health and recovery. Perinatal specialists and researchers should continue to focus on tailored treatments specific to this special population.

Ethnic disparities in receiving benefits for disability following postpartum mental illness during first two years after delivery: an Israeli nationwide study.

BACKGROUND: Despite relatively high rates of Postpartum Depression (PPD), little is known about the granting of social security benefits to women who are disabled as a result of PPD or of other postpartum mood and anxiety disorders (PMAD). This study aims to identify populations at risk for underutilization of social security benefits due to PMAD among Israeli women, with a focus on ethnic minorities. METHODS: This retrospective cohort study is based on the National Insurance Institute (NII) database. The study population included a simple 10% random sample of 79,391 female Israeli citizens who gave birth during 2008-2016 (these women delivered a total of 143,871 infants during the study period), and who had not been eligible for NII mental health disability benefits before 2008. The dependent variable was receipt of Benefit Entitlement (BE) due to mental illness within 2 years following childbirth. Maternal age at delivery, population group, Socio-Economic Status (SES), family status, employment status of the mother and her spouse, and infant mortality were the independent variables. Left truncation COX proportional hazard model with time-dependent variables was used, and birth number served as a time discrete variable. RESULTS: Bedouin and Arab women had significantly lower likelihood of BE (2.6 times lower and twice lower) compared with other ethnic groups (HR = 0.38; 95% CI: 0.26-0.56; HR = 0.47; 95% CI: 0.37-0.60 respectively). The probability of divorced or widowed women for BE was significantly higher compared to those living with a spouse (HR = 3.64; 95% CI: 2.49-5.33). Lack of employment was associated with higher likelihood of BE (HR = 1.54; 95% CI: 1.30-1.82). Income had a dose-response relationship with BE in multivariable analysis: lower income was associated with the nearly four-fold greater probability compared to the highest income quartile (HR = 3.83; 95% CI: 2.89-5.07). CONCLUSIONS: Despite the exceptionally high prevalence of PMAD among ethnic minorities, Bedouins and Arabs had lowest likelihood of Benefit Entitlement. In addition to developing programs for early identification of postpartum emotional disorders among unprivileged ethnic groups, awareness regarding entitlement to a mental health disability allowance among ethnic minorities should be improved.

Relation between Mother's Taekyo, Prenatal and Postpartum Depression, and Infant's Temperament and Colic: A Longitudinal Prospective Approach.

This longitudinal cohort correlational study aimed to confirm the relation among taekyo or traditional prenatal practice, prenatal depression, postpartum depression, maternal-fetal interaction, and infant temperament and colic using a prospective design. We recruited 212 women 16-20 weeks pregnant from July 2017 to September 2018; they were followed up until six months postpartum. Data from 97 participants were used in the final analysis. We used the Edinburgh Postnatal Depression Scale, Cranley's Maternal-Fetal Attachment Scale, and What My Baby Is Like as measurement tools. We observed a significant correlation between prenatal maternal depression in the first to third trimesters and 6-8 weeks and six months postpartum. In addition, infant temperament at six months old showed a significant negative correlation with prenatal and postpartum depression: the higher the prenatal and postpartum depression level, the more difficult the infant's temperament. Taekyo practice was significantly related to maternal-fetal attachment (r = 0.45-0.68, p < 0.001). Difficult infants showed more colic episodes than any other type of infant (χ2 = 18.18, p < 0.001). Prenatal and postnatal maternal depression affected infants' temperament and colic episodes. The management of mothers' mental health before and after pregnancy is important for infants' and mothers' health.

Risk factors for postpartum depression: An evidence-based systematic review of systematic reviews and meta-analyses.

PURPOSE: Postpartum depression (PPD) is the most common psychiatric condition after childbirth which not only effects the mother's health, but also might have impact on child's development and parenting behaviors. Because the etiology of PPD has not been fully cleared, the efforts towards identification of risk factors are crucial for both the children and mother's health. METHOD: PubMed, EMBASE and PsycINFO databases were searched since inception until July 2019 to collect data about the risk factors of PPD and only systematic review and meta-analysis can be included. RESULT: To identify the real risk factors, protective factors and controversial factors, nineteen parts of the interpretation were adopted. The risk factors are mainly concentrated in the following aspects: violence and abuse, immigration status, gestational diabetes, cesarean section, depressive history, vitamin D deficiency, obese and overweight, postpartum sleep disruption and poor postpartum sleep, lack of social support, traditional dietary pattern (Japanese, Indian, United Kingdom, and Brazilian dietary pattern), multiple births, preterm and low-birth-weight infants, postpartum anemia, negative birth experience. The controversial factors are serum level of cortisol, thyroid peroxidase autoantibodies status, acculturation, traditional confinement practices. Skin-to-skin care, higher concentrations of DHA in mothers' milk, greater seafood consumption, healthy dietary patterns, multivitamin supplementation, fish and PUFA intake, calcium, Vitamin D, zinc and possibly selenium are protective factors. CONCLUSION: Thirteen risk factors were identified, but five factors still controversial due to the insufficient of the evidence. What's more, skin-to-skin care and some nutrition related factors are protective factors against PPD.

Perinatal depression: Data-driven subtypes derived from life history and mindfulness and personality.

BACKGROUND: Perinatal depression is the most prevalent mental disorder during the perinatal period, and research suggests that it presents heterogeneously. We aimed to explore how subtypes of perinatal depression present in terms of multivariate patterns of stable characteristics. METHODS: A cohort study was conducted from March 2016 to March 2018 with Chinese women in the prenatal period (n = 3186). Of the participants, 682 (21.41%) women with Edinburgh Postnatal Depression Scale scores ≥10, indicating probable depression, were included, with the remaining 2504 (78.59%) representing the control group. We assessed mood distress, cognition, life history, emotional regulation, and personality, and used latent class analysis and latent transition analysis to identify perinatal depression subtypes. Of the 682 women with probable depression, only 598 were included in the full analyses, as they completed at least 10 questionnaires. A second, non-overlapping sample and a follow-up cohort were used. RESULTS: We identified four subtypes: 1) a highly distressed type characterized by distress across all domains, high levels of rumination and neuroticism, and reduced trait mindfulness; 2) two moderately distressed types: one with high trauma and low perceived social support, and another with low trauma, high perceived social support, and expressive suppression; and 3) a slightly distressed subtype. LIMITATIONS: We only collected cost and time spent in hospital from medical records. We only had a small follow-up sample. CONCLUSIONS: This multidimensional subtyping of women with perinatal depression could help reduce the apparent heterogeneity of perinatal depression. Distinguishing the subtype characteristics facilitates identifying underlying causes of perinatal depression.

The Effect of Iodine-Containing Vitamin Supplementation During Pregnancy on Thyroid Function in Late Pregnancy and Postpartum Depression in an Iodine-Sufficient Area.

The purpose of this study was to investigate the effect of iodine supplementation during pregnancy on thyroid function and also its effect on postpartum depression in an iodine-sufficient area. Healthy pregnant women were divided into three groups: group A (vitamin iodine-150) receiving vitamin containing 150 µg iodine, group B (vitamin iodine-0) receiving vitamin without iodine, and group C (no vitamin) receiving no vitamin. General information was collected by questionnaire and thyroid function was determined in the third trimester of pregnancy. Depression was assessed 1 month postpartum by the Edinburgh postnatal depression scale (EPDS). The results showed that there was no significant difference in thyroid-stimulating hormone (TSH) level among the three groups (P > 0.05). FT4 concentration was significantly lower in group A (n = 234: 10.68 pmol/L) than in group B (n = 220: 11.47 pmol/L) and group C (n = 195: 11.64 pmol/L) (P < 0.05), However, it was still within the normal range. EPDS scores obtained from group B (3.50) and group C (3.00) were similar but markedly lower than group A (5.00) (P < 0.05). Despite the difference in the EPDS score, the prevalence of postpartum depression was not significantly different among the three groups. In conclusion, 150 µg/day iodine supplementation for pregnant women in areas with adequate iodine had little effect on thyroid function in the third trimester, and serum FT4 level could not be increased. Iodine supplementation during pregnancy also had no significant effect on postpartum depression.
