Summary of Research
Postpartum depression (PPD) is described as “a common and significant public health issue,” with depressive symptoms associated with “a wide variety of negative maternal and child health outcomes, disrupted maternal-child bonding, and long-term cognitive, emotional, and behavioral development problems in children.” Although “there is a growing consensus on the importance of screening for PPD symptoms,” a significant proportion of women remain undetected or undiagnosed, making it “an important public health task to identify risk factors of PPD.” Adverse childhood experiences (ACEs) “have been linked to long-term physical, mental, and behavioral health challenges,” and “individuals with high ACEs exposure face increased risks for chronic mental health problems and mood disorders, such as PPD, due to the cumulative effects of early life stress on emotional regulation and neurobiological functioning.” Because previous research has predominantly examined “the dosage effect of ACEs on PPD by using a count of different types of ACEs,” the study used a person-centered approach to provide “a more nuanced examination of the relation between exposure to ACEs and PPD.” The study had three aims: “(a) to identify latent classes of women based on their patterns of exposure to ACEs, (b) to examine the associations between latent class membership and PPD symptoms, adjusting for the effects of covariates, and (c) to determine whether latent class membership is associated with PPD screening” (p. 905 - 906).
“The present study utilized a sample of 427 women at a large university medical center who participated in the Longitudinal Infant and Family Environment (LIFE) study.” “Follow-up data were collected around seven days via nurses at home visitation and three months postpartum via online survey.” Participants “retrospectively reported their exposure to ACEs before age 18,” while PPD symptoms were measured using “the modified version of the Patient Health Questionnaire-2 (PHQ-2).” Screening for PPD was assessed by asking whether participants had received “a postpartum checkup” and whether “a doctor, nurse, or other health care worker” had asked if they were “feeling down or depressed.” “Latent class analysis (LCA) was used to identify distinct ACEs exposure classes,” and “the associations between ACEs classes and two distal outcomes (i.e., PPD symptoms and screening for PPD) were examined using the maximum likelihood (ML) three-step approach” (p. 906 - 907).
Around “62.5% of the study participants were exposed to at least one ACE, 15.0% were exposed to four or more ACEs, and on average were exposed to 1.6 ACEs.” The analyses identified three groups: “Low ACEs (57% of the sample),” “High Parental Separation/Divorce” (30%), and “High/Multiple ACEs (13% of the sample).” The High/Multiple ACEs class “had a high probability of exposure to seven ACEs” and “a moderate probability of exposure to two ACEs.” After controlling for covariates, “a significant link between ACEs classes and depression symptoms” was found. Compared with women in the Low ACEs class, “those in the High Parental Separation/Divorce class… and High Multiple ACEs class… reported significantly greater PPD symptoms.” Moreover, “participants in the High Multiple ACEs class demonstrated significantly greater depressive symptoms than those in the High Parental Separation/Divorce class.” Despite these differences in symptoms, “no statistically significant differences in screening for depression were found across the three classes” (p. 907 - 909).
“The present study illuminates the relationship between maternal ACEs and PPD.” Maternal ACE patterns “were differently associated with PPD symptoms,” such that women with “high levels of exposure to ACEs (i.e., high parental separation/divorce and high/multiple ACEs) reported significantly higher levels of depressive symptoms in comparison to those exposed to low ACEs.” Most notably, “those exposed to high/multiple ACEs reported the highest rates of depressive symptoms.” The findings “suggest screening for more nuanced ACEs profiles, rather than cumulative measures alone, are critical for more effective PPD screening” and provide “a more comprehensive picture of how maternal ACEs relate to both mental health and service engagement in the early postpartum period.” The authors further suggest that “exposures to multiple types of ACEs at high levels are a more important predictor of PPD symptoms than the specific types of ACEs that are experienced” (p. 910).
This pattern “may be due to stress sensitization that occurs as a result of frequent exposure to external stressors, such as ACEs.” According to this model, “exposure to multiple and/or repeated ACEs lowers the threshold necessary for future stressors to trigger symptoms of mental disorders, such as major depressive disorder.” Exposure to early life stress “has been shown to alter the regulation of cortisol, the primary stress hormone, resulting in either hyper- or hypo-responsiveness to stress in adulthood,” and “exposure to multiple types of ACEs may increase vulnerability to PPD through disruptions in stress-related neuroendocrine circuits.” Women with multiple ACEs may also face increased risk “due to re-traumatization upon recall of their own childhood experiences and memories” and may “lack social support (e.g., family support), which is a key promotive factor for mental health during the transition to motherhood.” Although the study “found no significant differences in screening for PPD based on patterns of ACEs,” the findings indicate that “screening for maternal ACEs can help to identify women who may be at higher risk for PPD symptoms during the perinatal period” (p. 910 - 911).
