Similarities and differences between postpartum depression and depression at other stages of female life: a systematic review

Mendelian randomization analyses for the causal relationship between early age at first sexual intercourse, early age at first live birth, and postpartum depression in pregnant women

Introduction

There are insufficient epidemiological studies on the impact of age at first sexual intercourse (AFS) and age at first live birth (AFB) on postpartum depression (PPD) in pregnant women, and the conclusions of these studies are inconsistent.

Methods

We performed a Mendelian randomization (MR) study to determine the causal relationship between AFS or AFB and the risk of PPD. The summary data were extracted from genome-wide association study (GWAS) summary datasets. We selected the instrumental variables according to the P value of exposure-related single nucleotide polymorphisms (P<5 ×10-9 for AFS and P<5 ×10-8 for AFB) and estimated the linkage disequilibrium using the clump parameter (10,000 kb, r2 < 0.001). Single nucleotide polymorphisms were considered instrumental variables that were significantly associated with exposure factors without linkage disequilibrium. The F-statistics of the instrumental variables should all be larger than 10. A random-effects model of IVW was constructed as the main method in our study.

Results and discussion

MR studies based on GWAS data revealed that both AFS (OR = 0.4, P <0.001) and AFB (OR = 0.38, P <0.001) were negatively correlated with the risk of PPD. Early AFS and early AFB should be studied as possible risk factors for PPD in the future. Public health departments should attach importance to sex education for young girls. The results of our TSMR should be verified by high-quality prospective epidemiological studies in the future.

Trajectories of cognitive reactivity and its predictive value on postpartum depression in Chinese women: a latent class growth modeling analysis

Many women are experiencing postpartum depression (PPD) after giving birth. How to recognize and intervene in high-risk PPD women early and effectively remains unknown. Our objective is to describe the latent trajectory groups of cognitive reactivity (CR) in perinatal women, and their relationship to demographic and disease-related factors, as well as investigate the associations with PPD. Data from 321 perinatal women who were evaluated in urban tertiary hospitals in China at three-time points: 32-35 weeks of pregnancy, 1 week postpartum, and 6 weeks postpartum. Latent class growth modeling was used to identify the trajectory patterns of CR and logistic regression was used to explore the association between demographic and disease-related factors, CR trajectories, and depression. Three trajectory groups were identified: the continuing deterioration group (17.2%), the postpartum deterioration group (22.1%), and the consistent resilient group (60.7%). Participants with a bachelor's degree or higher and with gestational diabetes diagnosis were more likely to be in the continuing deterioration group. Those who were from only-child families were more likely to be in the postpartum deterioration group. Women in the continuing deterioration group and postpartum deterioration group were more likely to experience PPD. Targeted interventions should be developed based on trajectory group of CR.

Symptoms of Depression in the Postpartum Period: Targeting Maternal Mental Health in the Perinatal Period

This cross-sectional study aimed to examine the relationship between postpartum depression symptoms, anxiety, and stress during the postpartum period. A total of 101 women were assessed using the Depression, Anxiety and Stress Scale (DASS-21) and the Edinburgh Postnatal Depression Scale (EPDS) within 14 days after delivery. Multivariate regression analysis revealed that paid work, tobacco use, and stress symptoms were significantly associated with a higher incidence of postpartum depression symptoms. These results underscore the importance of comprehensive prenatal care and effective postpartum follow-up to address maternal mental health and prevent adverse outcomes for both mothers and children.

Health anxiety, death anxiety and coronaphobia: Predictors of postpartum depression symptomatology during the COVID-19 pandemic

OBJECTIVE

To determine levels of postpartum depression symptoms and possible relevant predictors, such as death anxiety, health anxiety, and coronavirus-related anxiety.

DESIGN

Cross-sectional web-based survey using quantitative methods.

SETTING

Exclusively online recruiting via social media and unpaid cross-posting conducted during the third wave of the COVID-19 pandemic in Romania.

PARTICIPANTS

Women were eligible to take part in the study if they were mothers over the age of 18 and had a baby aged between 4 weeks - 12 months of age; 1024 women were included in the final sample.

MEASUREMENTS AND FINDINGS

Health anxiety, death anxiety, coronavirus-related anxiety, and postpartum depression symptoms were measured using validated instruments. Current depression symptomatology was 67.6%, 26.7% scored above the cut-off for high health anxiety, 1% for coronavirus-related anxiety, and 62.7% for death anxiety. Significant predictors for depressive symptomatology were breastfeeding, history of depression, family income, number of children, health anxiety, death anxiety, and coronavirus anxiety. Further, hierarchical multiple regression analysis indicated that death anxiety, health anxiety, and coronavirus anxiety predicted postpartum depression symptoms over and above socio-demographic factors.

KEY CONCLUSIONS

Supported by previous studies, our results suggest that postpartum depression symptomatology levels during the COVID-19 pandemic are high and that they are predicted by health and death anxiety, which are also increased during the pandemic.

IMPLICATION FOR PRACTICE

The findings provide information to identify the risk for depression symptoms in postpartum mothers during acute public health situations.
