Social dynamics of postpartum depression: a population-based screening in South-Eastern Hungary

Perinatal Depression and Risk of Suicidal Behavior

Importance

Suicidal ideation is common among women with perinatal depression (PND). However, prospective data are limited on the risk, particularly long-term risk, of suicidal behavior (suicide attempt and completed suicide) among women with perinatal depression.

Objective

To examine the association between PND and risk of short- and long-term suicidal behavior.

Design, Setting, and Participants

A nationwide population-matched cohort study was conducted in Sweden including 86 551 women with PND from 2001 to 2017 and 865 510 unaffected women individually matched on age and calendar year at delivery. Sibling comparison was used to account for familial confounding. Data were analyzed from January 2022 to November 2023.

Exposure

PND was identified through depression diagnosis or filled prescriptions of antidepressants from pregnancy to 1 year post partum in registers.

Main Outcomes and Measures

All women were followed up for the first event of suicidal behavior recorded in registers. Hazard ratios (HR) of suicidal behavior were estimated using time-to-event analysis.

Results

Women with PND (86 551 participants) received a diagnosis at a mean (SD) age of 30.67 (5.23) years. During a median (IQR) follow-up of 6.91 (3.62-10.88) years, 3604 events of suicidal behavior (incidence rate [IR], 5.62 per 1000 person-years) were identified among women with PND and 6445 (IR, 1.01 per 1000 person-years) among population-unaffected women. Women with PND had an elevated risk of suicidal behavior when compared with matched unaffected women (HR, 3.15; 95% CI, 2.97-3.35). Comparable, albeit somewhat attenuated, associations were yielded when comparing PND women with their PND-free sisters (HR, 2.75; 95% CI, 2.10-3.61). In the population-matched cohort, the association was greater for postnatal depression and among women without a history of psychiatric disorders. The excess risk was pronounced during the first year after diagnosis (HR, 7.20; 95% CI, 6.07-8.54), yet remained statistically significant during 5 to 18 years of follow-up (HR, 2.34; 95% CI, 2.12-2.57).

Conclusions and Relevance

In this nationwide cohort study, women with PND were at an increased risk of suicidal behavior, particularly within the first year after diagnosis with persistent risk elevations throughout the 18 years of follow-up, highlighting the need for vigilant clinical monitoring of this vulnerable group.

Risk Factors of Postpartum Depression

Postpartum depression (PPD) is a widespread mental health problem and one of the prime causes of maternal suffering and ill health. On a global level, the prevalence of the disorder is about 10 to 15%. Symptoms generally appear within the first four to six weeks, which is the high-risk period. However, it may develop up to one year post-delivery. PPD presents with symptoms of classical depression, including mood fluctuations, bouts of crying, lack of interest in the child, and even thoughts of suicide. PPD not only has adverse effects on the mother's health but also hampers the growth and development of the child. It hampers the formation of a healthy mother-child bond, which in turn may impact feeding practices. The social environment of the infant during the first few months is primarily provided by the mother, and PPD may thus impact the child's development. It also increases the child's susceptibility to malnutrition. Research on postpartum depression has garnered momentum within the last few years. However, the masses are still largely unaware of the disorder and its implications. There is also an inadequacy of awareness of the risk factors of PPD. The cross-cultural differences in manifestations and appropriate preventive measures have not been extensively studied. Some risk factors for PPD are similar to those for classic depression; however, obstetrical and pediatric factors are also involved. This literature review aims to assess the currently known risk factors for PPD, their strength of association, and probable mechanisms to help identify the high-risk group and enable the implementation of preventive measures or facilitate early diagnosis. The factors identified spanned sociodemographic, biological, psychological, and obstetric domains. These included socioeconomic standing, marital relationship, history of psychiatric illness, social support, gestational diabetes, vitamin D deficiency, immigration status, delivery method, violence and abuse, birth experience, and biological and epigenetic markers. The risk factors for postpartum depression are numerous and may have strong to weak associations with the development of PPD. A previous history of depression or psychiatric illness, depressive symptoms during pregnancy, gestational diabetes, and a lack of spousal and social support were the most powerful risk factors. Other significant factors include complications during pregnancy, low socioeconomic status, and stressful life events. Studies on maternal age and chronic illness as risk factors were inconclusive. The roles of genetic and epigenetic markers, cultural factors, and vitamin D insufficiency require further investigation.

Prevalence and risk factors of maternal depression among women who participated in a home visitation program in South Korea

PURPOSE

The psychosocial health of mother is crucial for healthy prenatal period and early childhood. We investigated the prevalence and risk factors of maternal depression during pregnancy and postpartum among women who participated in a home visitation program in Seoul, South Korea (Seoul Healthy First Step Project, SHFSP).

METHODS

We analyzed 80,116 women who participated in the SHFSP, which was launched by Seoul metropolitan government in 2013, and defined peripartum depression as a score ≥ 10 on the Korean version of the Edinburgh Postnatal Depression Scale (EPDS). Sociodemographic factors and psychosocial health status were evaluated through a standardized questionnaire completed by participants upon program registration. We calculated the prevalence of women at risk for peripartum depression and evaluated associated factors by multivariable logistic regression analysis.

RESULTS

Prevalence of women at risk for peripartum depression was 17.7% (prepartum depression: 14.2%, postpartum depression: 24.3%). Younger maternal age, low income (OR 2.40, 95% CI 2.03-2.84), disability (2.61, 1.96-3.47), single parenthood (3.27, 2.69-3.99), and smoking (2.02, 1.44-2.83) increased the peripartum depression risk. Furthermore, experience of stress, change, or loss over the past 12 months (3.36, 3.22-3.50), history of treatment for emotional issues (2.47, 2.27-2.70), experience of child abuse (1.91, 1.74-2.11), and domestic violence (2.25, 1.81-2.80) increased the risk for peripartum depression, whereas having helpers for the baby (0.62, 0.58-0.67), having someone to talk with (0.31, 0.27-0.35), and considering oneself confident (0.30, 0.29-0.31) decreased the risk.

CONCLUSIONS

Policies to reduce and manage peripartum depression should be strengthened, with a focus on high-risk pregnant and puerperal women.

Caesarean delivery and the use of antidepressants

BACKGROUND

The high ratio of caesarean sections (C-sections) is a major public health issue in the developed world; but its implications on maternal mental health are not well understood.

METHODS

We use individual-level administrative panel data from Hungary between 2010 and 2016 to analyze the relationship between caesarean delivery and antidepressant consumption, an objective indicator of mental health. We focus on low-risk deliveries of mothers without subsequent birth in 3 years, and include around 135 000 observations.

RESULTS

After controlling for medical and socio-economic variables, antidepressant use before delivery is associated with an elevated risk of C-section (adjusted OR = 1.10, 95% CI 1.05-1.14) and C-section is associated with a higher probability of antidepressant use within 1-3 years after delivery (e.g. adjusted OR = 1.21, 95% CI 1.12-1.30, within 3 years after delivery, among mothers without pre-delivery antidepressant consumption). Our data restriction ensures that the results are not driven by a mechanical impact of decreasing fertility on the continuation of antidepressant use after a C-section.

CONCLUSIONS

The results suggest that C-section is associated with worse mental health over the 1- to 3-year horizon after birth. This relationship is particularly important if a caesarean delivery is not necessary due to medical reasons, and physicians as well as expectant mothers should be made aware of the potential mental health implications of the mode of delivery.

Prevalence and incidence of postpartum depression and environmental factors: The IGEDEPP cohort

BACKGROUND

IGEDEPP (Interaction of Gene and Environment of Depression during PostPartum) is a prospective multicenter cohort study of 3310 Caucasian women who gave birth between 2011 and 2016, with follow-up until one year postpartum. The aim of the current study is to describe the cohort and estimate the prevalence and cumulative incidence of early and late-onset postpartum depression (PPD).

METHODS

Socio-demographic data, personal and family psychiatric history, as well as stressful life events during childhood and pregnancy were evaluated at baseline. Early and late-onset PPD were assessed at 8 weeks and 1 year postpartum respectively, using DSM-5 criteria.

RESULTS

The prevalence of early-onset PPD was 8.3% (95%CI 7.3-9.3), and late PPD 12.9% (95%CI 11.5-14.2), resulting in an 8-week cumulative incidence of 8.5% (95%CI 7.4-9.6) and a one-year cumulative incidence of PPD of 18.1% (95%CI: 17.1-19.2). Nearly half of the cohort (N = 1571, 47.5%) had a history of at least one psychiatric or addictive disorder, primarily depressive disorder (35%). Almost 300 women in the cohort (9.0%) reported childhood trauma. During pregnancy, 47.7% women experienced a stressful event, 30.2% in the first 8 weeks and 43.9% between 8 weeks and one year postpartum. Nearly one in five women reported at least one stressful postpartum event at 8 weeks.

CONCLUSION

Incident depressive episodes affected nearly one in five women during the first year postpartum. Most women had stressful perinatal events. Further IGEDEPP studies will aim to disentangle the impact of childhood and pregnancy-related stressful events on postpartum mental disorders.

Post-partum depression: a cross-sectional study of women enrolled in a conditional cash transfer program in 30 Brazilian cities

OBJECTIVE

Investigate factors associated with symptoms of postpartum depression in mothers from families in social vulnerability.

METHODS

Information was used from the baseline of a randomized trial to assess a child development program that enrolled 3,242 children < 12 months of age from beneficiary families of the Bolsa Família Program residing in 30 municipalities (counties) in six states of Brazil. The Edinburgh Postnatal Depression Scale (EPDS) was applied to the mothers, and depression was defined as score ≥10. Information on the mother (schooling, age, parity, marital status, skin color, smoking, number of prenatal appointments, and planning of the pregnancy), family (paternal schooling, household crowding, support from the child's father and the family during the pregnancy, and number of children under 7 years living in the household), and infant (sex, gestational age, birthweight, Apgar score, and child's age at the time of the interview) was collected. Prevalence rates for depressive symptoms were calculated with crude and adjusted odds ratios (OR) and 95% confidence intervals (95%CI), using hierarchical logistic regression, in a multilevel model.

RESULTS

The analysis included 3,174 mothers with information on EPDS. The interviews were conducted on average 7.9 months (standard deviation= 2.9) after childbirth. Overall prevalence of depressive symptoms was 26.5% (25.0-28.1%). In the adjusted analysis, higher parity was associated with higher odds of postpartum depression (p <0.001). Women with ≥3 previous deliveries showed an odds 84% higher of presenting depressive symptoms (OR= 1.84; 1.43-2.35) than primiparae. Higher maternal and paternal schooling, presence of husband or partner, and having received support from the child's father and the family during the pregnancy were protective factors against postpartum depression.

CONCLUSION

The study showed high prevalence of postpartum depressive symptoms. Promotion of parental education, alongside with the promotion of support to the woman during pregnancy by the child's father and by the family, as well as family planning leading to birth spacing are measures that may help to prevent postpartum depressive symptoms.

Social determinants of peripartum depressive symptoms among Black peripartum women living with HIV

HIV infection during pregnancy, may present risk of developing depression during pregnancy and postpartum. This psychiatric mood disorder, and many others such as anxiety and HIV-related post-traumatic stress disorder (PTSD) have been reported prevalent among pregnant and non-pregnant women living with HIV (WLWH). Multiple studies have found associations between social determinants of health and depressive symptoms in this population. However, despite deleterious effects on mother and child which may include suicidal ideations and infant death, only very few studies have examined this phenomenon for peripartum women, particularly Black women- a population prone to living in poor social and economic environments. Therefore, guided by the socio-ecologic model, this study examined predictors of peripartum depressive symptoms among Black peripartum WLWH. The study was a secondary data analysis of 143 Black women seen at special prenatal and women's health clinics in Miami, South Florida, USA. More than half of the women who experienced peripartum depressive symptoms (PDS) (n = 81, 57%) were of low socio-economic status. Low income was associated with increased odds of experiencing PDS. Women who endorsed intimate partner violence/abuse (IPV/A) were 6.5 times more likely to experience PDS; and compared to women with 1 or no childcare burden, women with 2 children-care burden were 4.6 times more likely to experience PDS. These findings demonstrate the negative impact of social factors on the psychological health of Black peripartum WLWH. Burdensome interpersonal relationships may have deleterious effects and trigger PDS among these women. Implications for nursing practice, education and research are also discussed.

Risk of Postpartum Depression Among Women with Asthma

BACKGROUND

Several epidemiological studies have suggested that the risk of depression is increased in patients with asthma, but the impact of asthma during pregnancy on postpartum depression remains unknown.

OBJECTIVE

To assess the association between maternal asthma and postpartum depression in a population-based cohort study retrieved from administrative databases.

METHODS

A cohort of 35,520 pregnancies in women with asthma during pregnancy and 197,057 pregnancies in women without asthma who delivered between 1998 and 2009 was extracted from the Quebec Asthma and Pregnancy Database. They were followed from the day of delivery up to 1 year postpartum. A generalized estimating equation model was used to estimate the adjusted odds ratios of postpartum depression with 95% CIs in women with asthma during pregnancy versus women without asthma.

RESULTS

Postpartum depression within 1 year after delivery occurred in 6.1% of women with asthma versus 2.9% of women without asthma. After adjusting for several potential confounders, including depression/postpartum depression up to 10 years before pregnancy, we found that women with asthma were 58% more likely to experience postpartum depression within 1 year after delivery than women without asthma during pregnancy (adjusted odds ratio, 1.58; 95% CI, 1.50-1.67).

CONCLUSIONS

Our findings suggest that women with asthma are more likely to suffer from postpartum depression. A close monitoring of signs of depression for pregnant women with asthma is indicated, allowing prompt and efficient interventions if needed.

Eine meta-analytische Untersuchung des sozioökonomischen Status als Risikofaktor für postpartale Depression

Zusammenfassung. Theoretischer Hintergrund: 13 % aller Gebärenden leiden an postpartalen Depressionen (PPD), einer Krankheit mit bedeutsamen gesundheitlichen und sozialen Konsequenzen für die Betroffenen. Zurzeit werden PPD jedoch häufig spät erkannt und behandelt. Eine Früherkennung könnte durch die Identifikation spezifischer Vulnerabilitätsfaktoren erleichtert werden. Niedriger sozioökonomischen Status (SES) wurde als potenzieller Risikofaktor für Depressionen diskutiert ( Lorant et al., 2003 ). Fragestellung: Das Ziel der vorliegenden Meta-Analyse ist die systematische Untersuchung, ob niedriger SES mit einem erhöhten Risiko für die Entwicklung einer PPD einhergeht. Methode: Um die Vergleichbarkeit der eingeschlossenen Studien zu gewährleisten, werden die internationalen Empfehlungen zur Erfassung des SES von Jöckel et al. (1998) als Inklusionskriterium herangezogen. Die identifizierten Studien werden meta-analytisch zusammengefasst. Ergebnisse: Weder Bildung mit einem relativen Risiko (RR) = 1.14 (95 % KI = 0.95, 1.45) noch Einkommen mit RR = 1.32 (95 % KI = 0.99, 1.74) waren signifikant mit der Entwicklung einer PPD assoziiert. Schlussfolgerung: Es wurde kein Zusammenhang zwischen dem erhöhten Risiko eine PPD zu entwickeln und dem Bildungsniveau oder dem Einkommen gefunden. Die vorliegende Studie macht auf die gravierenden methodischen Mängel im Bereich der Forschung von PPD und dem SES aufmerksam.

Review of the prevalence of postnatal depression across cultures

The purpose of this review was to examine articles related to recent epidemiological evidence of the prevalence of maternal postnatal depression (PND) across different countries and cultures and to identify specific epidemiological studies that have been carried out exclusively in Malaysia on the prevalence of maternal PND. The review was undertaken in two stages, an initial review and an updated review. At both stages systematic literature searches of online databases were performed to identify articles on the prevalence of maternal PND. A total of 124 articles concerning research conducted in more than 50 countries were included in the final analysis. There were wide variations in the screening instruments and diagnostic tools used although the Edinburgh Postnatal Depression Scale (EPDS) was the most common instrument applied to identify PND. The prevalence of maternal PND ranged from 4.0% to 63.9%, with Japan and America recording the lowest and highest rates, respectively. Within continents, a wide variation in reported prevalence was also found. The reported rates of maternal PND in Malaysia were much higher than that previously documented with a range of 6.8–27.3%. This review indicated that the widely cited prevalence of maternal PND of 10–15% underestimates rates of PND worldwide. The reasons for this variability may not be fully explained by review methods. Future studies should evaluate the nature of women's PND experiences across cultures to explain these wide variations.

Magnitude and risk factors for postpartum symptoms: a literature review

BACKGROUND

The prevalence of postpartum depression worldwide varies from 0.5% to 60.8% in the first 12 months postpartum using self-reported questionnaire. This review aims to update the current magnitude of postpartum depression based on self-reported questionnaire and clinical interview and explore its associated factors in developed and developing countries.

METHODS

A literature search conducted between 2005 and 2014 identified 203 studies, of which 191 used self-reported questionnaire in 42 countries and 21 used structured clinical interview in 15 countries. Nine studies used a combination of self-reported questionnaire and clinical interview.

RESULT

The prevalence of postpartum depression varies from 1.9% to 82.1% in developing countries and from 5.2% to 74.0% in developed countries using self-reported questionnaire. Structured clinical interview shows a much lower prevalence range from 0.1% in Finland to 26.3% in India. Antenatal depression and anxiety, previous psychiatric illness, poor marital relationship, stressful life events, negative attitude towards pregnancy, and lack of social support are significant contributors to postpartum depression.

LIMITATION

All studies are included irrespective of the methodological quality, such as small sample size and their inclusion could affect the generalizability of the results.

CONCLUSION

The current prevalence of postpartum depression is much higher than that previously reported, and similar risk factors are documented. A culturally sensitive cut-off score with adequate psychometric properties of the screening instruments should be available. In future studies, examining the physical, biological, and cultural factors in qualitative studies and in those with adequate methodological qualities is recommended.

Biological and psychosocial predictors of postpartum depression: systematic review and call for integration

Postpartum depression (PPD) adversely affects the health and well being of many new mothers, their infants, and their families. A comprehensive understanding of biopsychosocial precursors to PPD is needed to solidify the current evidence base for best practices in translation. We conducted a systematic review of research published from 2000 through 2013 on biological and psychosocial factors associated with PPD and postpartum depressive symptoms. Two hundred fourteen publications based on 199 investigations of 151,651 women in the first postpartum year met inclusion criteria. The biological and psychosocial literatures are largely distinct, and few studies provide integrative analyses. The strongest PPD risk predictors among biological processes are hypothalamic-pituitary-adrenal dysregulation, inflammatory processes, and genetic vulnerabilities. Among psychosocial factors, the strongest predictors are severe life events, some forms of chronic strain, relationship quality, and support from partner and mother. Fully integrated biopsychosocial investigations with large samples are needed to advance our knowledge of PPD etiology.

Obstetric and psychosocial risk factors for depressive symptoms during pregnancy

We aimed to determine the psychosocial and obstetric correlates of depressive symptomatology during pregnancy in South-Eastern Hungary. A total of 1719 women were screened for depression in four counties in 2006 and 2007, based on a Leverton Questionnaire (LQ) score of ≥12 at 14-24 weeks of gestation. The LQ scores indicated a probable depressive illness (PDI) in 17.2% of the study group. The best predictors in a multiple regression analysis were history of major depression (adjusted odds ratio [AOR]=3.23), and major life events (AOR=2.43). A perceived lack of social support from partner (AOR=1.79) and lack of support by family (AOR=1.23) were also significant determinants. Lack of planning of pregnancy (AOR=1.12) and a history of unfavourable obstetric outcome (AOR=1.42) also seem to predispose to PDI. Overall, psychosocial factors appeared important in the prediction of PDI, whereas economic features did not.

Can a brief antepartum preventive group intervention help reduce postpartum depressive symptomatology?

BACKGROUND

Psychosocial and psychological interventions are generally effective in reducing depressive symptomatology in the postpartum period. Our aim was to evaluate the effectiveness of a brief preventive group intervention for postpartum depression (PPD) in a naturalistic setting, and study the effect of this on social and psychological risk factors.

METHODS

We conducted a randomized controlled trial (n = 1,719) in south-eastern Hungary in 62 antepartum centers. Pregnant women (n = 710) underwent a 4-session preventive group intervention whereas a control group (n = 1,009) attended 4 sessions providing the same information given in usual care.

RESULTS

Our intervention appeared to significantly reduce the risk of PPD, as defined by Leverton Questionnaire total scores (OR = 0.69). It resulted in an absolute risk reduction of about 18% in those with antepartum depression and 0.5% in those with no depression at recruitment. A multiple logistic regression analysis revealed a much reduced risk in those with a perceived lack of partner support (OR = 0.4) in the treatment group. Unplanned pregnancy, an irreversible risk factor affecting every fifth woman, also seemed to have a reduced effect on PPD after our group intervention (OR = 0.81).

CONCLUSIONS

A brief preventive antepartum group intervention focusing on psychoeducation, stress management, improving coping mechanisms, and the development of social support can be effective in reducing postpartum depressive symptomatology.

Antenatal risk factors for postnatal depression: a prospective study of Chinese women at maternal and child health centres

BACKGROUND

Risk factors for postnatal depression (PND) are under-explored in the Chinese populations. There is increasing recognition of the importance of identifying predictive factors during the antenatal period for PND. The present study aimed to identify the risk factors for postnatal depression in a community cohort of Chinese women with special focus on the antenatal risk factors.

METHODS

Eight hundred and five Chinese women were interviewed during their third trimester of pregnancy and at around 2 months postnatally. Putative risk factors for PND were collected and the diagnosis of PND was confirmed by the Structured Clinical Interview for DSM-IV Axis I Disorders. The 2-month postnatal depression status was used as the dependent variable for univariate and multivariate analyses against putative risk factors.

RESULTS

Marital dissatisfaction (Relative Risk = 8.27), dissatisfied relationship with mother-in-law (Relative Risk = 3.93), antenatal depressive symptomatology (Relative Risk = 3.90), and anxiety-prone personality (Relative Risk = 2.14) predicted PND in Chinese women independently.

CONCLUSIONS

Chinese women tend to keep their own feelings and emotions and it is important to monitor Chinese pregnant women with these predictive risk factors so that PND can be identified early.

Alcohol misuse among partners: a potential effect modifier in the relationship between physical intimate partner violence and postpartum depression

PURPOSE

This study evaluated if the probability of postpartum depression (PPD) increases with an upward gradient of physical intimate partner violence (IPV) during pregnancy and whether substance use by any member of the couple modifies this relationship.

METHODS

The sample comprised 811 randomly selected mothers of children under 5 months old attending primary health services of Rio de Janeiro, Brazil. The Revised Conflict Tactics Scale (CTS2) gauged physical IPV, and the Edinburgh Postnatal Depression Scale (EPDS) assessed PPD. A hierarchical logistic regression model was employed to deal with confounding. Specific interaction terms between physical IPV and alcohol misuse or use of illicit drugs were also tested.

RESULTS

Physical IPV during pregnancy was reported by 37.8% of respondents and 24.3% were presumably depressed (EPDS score ≥ 12). Interaction between physical IPV and partners' alcohol misuse was statistically significant (p = 0.026). Although there was a significant increase in PPD with just one act of physical IPV in the absence of a partners' alcohol misuse, mounting acts did not have any further influence. Conversely, when partners misused alcohol, the probability progressively and steeply increased from two acts onwards, reaching almost sevenfold by six cumulative physical IPV events as opposed to none.

CONCLUSIONS

The results reinforce the relevance of physical IPV as a risk factor to PPD. They also suggest that context matters, partners' alcohol misuse acting as an important effect modifier. These evidences justify tailored preventive, screening and intervention procedures for IPV and alcohol misuse during pregnancy and the postpartum period.
