Sexual Trauma and Pregnancy: A Conceptual Framework

Prenatal Stress Exposure and Post-traumatic Stress Disorder Associated With Risk of Postpartum Alcohol Misuse Among Women Veterans

OBJECTIVES

Maternal alcohol misuse during the postpartum period is associated with negative maternal and infant outcomes. This study examined whether greater stress exposure in the year before the baby's birth and maternal post-traumatic stress disorder (PTSD) were associated with postpartum alcohol misuse among a sample of women veterans. Maternal PTSD was also examined as a moderator of the association between stress exposure and postpartum alcohol misuse.

METHODS

Data were drawn from the Center for Maternal and Infant Outcomes Research in Translation study, a multisite prospective cohort study of pregnant and postpartum women veterans. Interviews were conducted within 12 weeks after birth. At this post-birth interview, women reported whether they experienced stressful events (e.g., loss of job, military deployment, separation/divorce) in the year before birth. PTSD diagnosis and postpartum scores on the Alcohol Use Disorders Identification Test (AUDIT-C) were derived from the Department of Veterans Affairs medical records.

RESULTS

Models testing main and interaction effects showed a statistically significant association of both PTSD (p = .02) and stress exposure (p = .04), as well as significant interaction of PTSD and stress exposure (p = .03) with AUDIT-C scores postpartum, after controlling for marital status, age, and race. Specifically, compared with women without PTSD, those with PTSD had higher overall AUDIT-C scores postpartum, regardless of stress exposure. For women without PTSD, more stress exposure before birth was associated with higher AUDIT-C scores during the postpartum phase.

CONCLUSIONS

PTSD diagnosis and life stressors before infant birth predicted maternal alcohol misuse during the postpartum period. Identifying such risk factors is an initial step in preventing alcohol misuse, with the goal of enhancing postpartum health for the birthing parent and infant.

Perinatal Depressive Symptoms: Prevalence and Associated Psychosocial Factors

Perinatal depression is a major depression episode that starts during pregnancy and the postpartum period; and is an important cause of health risks in women and infants. A cross-sectional observational study was conducted with information from the records of 112 pregnant women or in the immediate postpartum period who were surveyed to determine the possible association between perinatal depressive symptoms and psychosocial factors occurring in the last year. The prevalence of clinically significant perinatal depressive symptoms using the Edinburgh scale was of 22.36%. The logistic regression model found association between clinically significant perinatal depressive symptoms (score on the Edinburgh scale ≥ 12 and the following psychosocial factors: end of the couple's relationship (OR=6.26; 95% CI, 1.91-20.49), severe economic problems (OR=6.61; 95% CI, 1.86-23.45), and the death of a family member (OR=3.79; 95% CI, 1.12-12.74). In this study one in four women had broken up with their partner and had severe economic problems during pregnancy, also one of ten had suffered the death of a loved one in the past year. These psychosocial factors were strongly associated with the presence of depressive symptoms with clinical importance. These finding offer the opportunity to consider psychosocial factors as a source of maternal stress that could be easily identified in the prenatal controls that pregnant women receive to identify women at risk of experiencing depressive symptoms in the perinatal period, which will enable appropriate treatment to be given to those who need it.

Prenatal sleep quality and mental health symptoms across the perinatal period: A longitudinal study of high-risk women

BACKGROUND

Trauma-exposed women may be at magnified risk for posttraumatic stress (PTSS) and depression symptoms in the perinatal period, but few studies have examined symptomatology across the perinatal period in high-risk samples. Further, the role of sleep in perinatal symptomatology has been largely neglected in the violence literature, despite its well-established associations to mental health in other samples. This study aimed to examine the trajectory of PTSS and depression symptoms across the perinatal period and the effects of childhood adversity, intimate partner violence and prenatal sleep impairment on PTSS and depression symptoms across the perinatal period.

METHOD

In a longitudinal, prospective study, 101 low-income pregnant women were interviewed during pregnancy, at 6-weeks postpartum, and 4 months postpartum. N = 83 women completed at least 2 interviews and were included in the analyses. Prenatal sleep, childhood adversity, and IPV exposure were assessed at the prenatal interview; PTSS and depression were assessed at all interviews.

RESULTS

Past year IPV was associated with elevated prenatal mental health symptoms and prenatal sleep difficulties were associated with a worsening trajectory in perinatal PTSS.

CONCLUSIONS

Screening for IPV and prenatal sleep difficulties may be paramount in identifying those at risk for the development or exacerbation of mental health symptoms in the perinatal period.

Antenatal Depression in a Tertiary Care Hospital

CONTEXT

Antenatal depression is not easily visible, though the prevalence is high. The idea of conducting this study was conceived from this fact.

AIMS AND OBJECTIVES

The aim of this study was to estimate the prevalence of antenatal depression and identify the risk factors, for early diagnosis and intervention.

SETTINGS AND DESIGN

The study conducted in a Tertiary Care Hospital was prospective and cross-sectional.

MATERIALS AND METHODS

Pregnant women between 18 and 40 years of age were studied. The sample size comprised 318 women. They were assessed using Edinburgh Postnatal Depression Scale (EPDS) score, Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders, Life Event Stress Scale (LESS), and Life Distress Inventory (LDI).

STATISTICAL ANALYSIS USED

The Statistical Package for Social Sciences (SPSS) Version 15 software was used to measure percentages, mean, correlation, and P < 0.05 were considered significant.

RESULTS

Prevalence of antenatal depression in the study was 12.3%. Correlation of the sociodemographic factors, obstetric factors, LDI, and LESS with EPDS scores showed statistical significance for unplanned pregnancy, distress associated with relationships, physical health, financial situation, social life, presence of personality disorder, being a homemaker, and higher educational status.

CONCLUSION

The study showed a high prevalence rate of depression and identified risk factors.

Depressive symptoms in the second trimester relate to low oxytocin levels in African-American women: a pilot study

Low-income African-American women report elevated prenatal depressive symptoms more often (42 %) than the national average (20 %). In the USA in 2012, 16.5 % of African-American women experienced a premature birth (less than 36 completed gestational weeks) compared to 10.3 % of white women. In addition, 13 % of African-American women had a low-birth weight infant (less than 2,500 g) compared to 7 % of white women. Variation in the neuropeptide, oxytocin has been implicated in perinatal depression, maternal behavior, regulation of stress responses, and may be associated with this health disparity. The purpose of this investigation was to examine factors associated with prenatal depressive symptoms, including plasma oxytocin levels and birth weight, in a sample of urban African-American women. Pregnant African-American women (N = 57) completed surveys and had blood drawn twice during pregnancy at 15-22 weeks and 25-37 weeks. In addition, birth data were collected from medical records. A large number of participants reported elevated prenatal depressive symptoms at the first (n = 20, 35 %) and the second (n = 19, 33 %) data points. Depressive symptoms were higher in multigravidas (t(51) = -2.374, p = 0.02), women with higher anxiety (r(47) = 0.71, p = 0.001), women who delivered their infants at an earlier gestational age (r(51) = -0.285, p = 0.04), and those without the support of the infant's father (F(4, 48) = 2.676, p = 0.04). Depressive symptoms were also higher in women with low oxytocin levels than in women with high oxytocin levels (F(2, 47) = 3.3, p = 0.05). In addition, women who had low oxytocin tended to have infants with lower birth weights (F(2, 47) = 2.9, p = 0.06). Neither prenatal depressive symptoms nor prenatal oxytocin levels were associated with premature birth. Pregnant multigravida African-American women with increased levels of anxiety and lacking the baby's father's support during the pregnancy are at higher risk for prenatal depressive symptoms. Prenatal depressive symptoms are associated with low oxytocin levels and lower infant birth weights. Further research is needed to understand the mechanisms between prenatal depressive symptoms, oxytocin, and birth weight in order to better understand this health disparity.

Sexual violence and antenatal hospitalization

BACKGROUND

Studies have shown the negative impact sexual violence has on pregnancy outcome, yet the impact on antenatal hospitalization has been poorly examined. The aim of this study was to investigate if a history of sexual violence was associated with hospitalization during pregnancy.

METHODS

A population-based national cohort study conducted by the Institute of Public Health, The Norwegian Mother and Child Cohort study. Women filled out questionnaires at 17 and 30 weeks' gestation. History of sexual violence was reported at three levels: pressured to sexual acts (mild), forced with violence (moderate), and raped (severe). The comparison group did not report sexual violence. Differences were assessed using Pearson's X(2) tests and logistic regression analyses.

RESULTS

Of 78,660 women, 12.0% were pressured to sexual acts, 2.8% forced with violence, and 3.6% reported rape. A history of sexual violence was associated with significantly more hospitalizations during pregnancy, 6.6 percent for mild, 8.7 percent for moderate and 12.5 percent for severe, compared to 5.8 percent for no sexual violence. Women were significantly more often admitted for hyperemesis, bleeding, threatening preterm birth, other reasons and admitted without giving any reason. Reporting severe sexual violence had an AOR for being hospitalized with hyperemesis or threatening preterm birth of 1.9 (95% CI 1.4-2.5), and 1.9 (1.3-2.7) respectively. Similarly, severe sexual violence was associated with being admitted more than once during pregnancy AOR 1.9 (1.3-2.7).

CONCLUSION

Women with a history of sexual violence reported significantly more antenatal hospitalizations during pregnancy than women without such a history.

Sexual violence and pregnancy-related physical symptoms

Background

Few studies have investigated the impact of sexual violence on health during pregnancy. We examined the association between sexual violence and the reporting of physical symptoms during pregnancy.

Methods

A population-based national cohort study conducted by The Norwegian Mother and Child Cohort study (MoBa) collected data from pregnant women through postal questionnaires at 17 and 32 weeks gestation. Three levels of sexual violence were measured: 1) mild (pressured into sexual relations), 2) moderate (forced with violence into sexual relation) and 3) severe (rape). Differences between women reporting and not reporting sexual violence were assessed using Pearson’s X² test and multiple logistic regression analyses.

Results

Of 78 660 women, 12.0% (9 444) reported mild, 2.8% (2 219) moderate and 3.6% (2 805) severe sexual violence. Sexual violence was significantly associated with increased reporting of pregnancy-related physical symptoms, both measured in number of symptoms and duration/degree of suffering. Compared to women not reporting sexual violence, the probability of suffering from ≥8 pregnancy-related symptoms estimated by Adjusted Odds Ratio (AOR) was 1.49 (1.41–1.58) for mild sexual violence, 1.66(1.50–1.84) for moderate and 1.78 (1.62–1.95) for severe. Severe sexual violence both previously and recently had the strongest association with suffering from ≥8 pregnancy-related symptoms, AOR 6.70 (2.34–19.14).

Conclusion

A history of sexual violence is associated with increased reporting of pregnancy-related physical symptoms. Clinicians should consider the possible role of a history of sexual violence when treating women who suffer extensively from pregnancy-related symptoms.

Depression and anxiety in perinatal period: prevalence and risk factors in an Italian sample

Accumulating evidence suggests that pregnancy does not protect women from mental illness. The aim of this study was to assess the prevalence, sociodemographic correlates, and the risks factors for perinatal depression and anxiety. Five hundred ninety women between 28th and the 32nd gestational weeks were recruited and submitted to a sociodemographic, obstetric, and psychological interview. The Edinburgh Postnatal Depression Scale (EPDS) and the state-trait anxiety inventory (STAI-Y) were also administered in antenatal period and 3 months postnatally. The Structured Clinical Interview for DSM-IV (SCID-I) was used to diagnose mood and anxiety disorders. Three months after delivery, EPDS was administered by telephone interview. Women with an EPDS score ≥10 were 129 in antenatal period (21.9%) and 78 in postnatal period (13.2%). During pregnancy 121 women (20.5%) were positive for STAI-Y state and 149 women (25.3%) for STAI-Y trait. The most important risk factors for antenatal depression are: foreign nationality, conflictual relationship with family and partner, and lifetime psychiatric disorders. The principal risk factors for postnatal depression are: psychiatric disorders during pregnancy and artificial reproductive techniques. Psychiatric disorders, during and preceding pregnancy, are the strongest risk factors for antenatal state and trait anxiety. Antenatal depressive and anxiety symptoms appear to be as common as postnatal symptoms. These results provide clinical direction suggesting that early identification and treatment of perinatal affective disorders is particularly relevant to avoid more serious consequences for mothers and child.

Developmental model of depression applied to prenatal depression: role of present and past life events, past emotional disorders and pregnancy stress

Background

Several risk factors for depression during pregnancy have already been established. However, very few studies have conducted a multivariate analysis incorporating both the major predictors of depression in women, in accordance with comprehensive developmental models of depression, and specific stressors associated with the biological and psychosocial state of the mother-to-be.

Methodology/Principal Findings

We used a cross-sectional cohort design to analyze the associations between prenatal depression and potential risk factors. 693 French-speaking women with singleton pregnancies at 20–28 weeks' gestation were consecutively recruited at Caen University Hospital. Fifty women with missing values were subsequently excluded from the analysis. Depressive symptoms were assessed on the Edinburgh Postnatal Depression Scale. Risk factors were either extracted from the computerized obstetric records or assessed by means of self-administered questionnaires. The associations between prenatal depression and the potential risk factors were assessed using log-binomial regression models to obtain a direct estimate of relative risk (RR). The following factors were found to be significant in the multivariate analysis: level of education (p<0.001), past psychiatric history (adjusted RR = 1.8, 95% confidence interval (CI): 1.1;2.8, p = 0.014), stress related to the health and viability of the fetus (adjusted RR = 2.6, 95% CI: 1.6;4.1, p<0.001), and stress related to severe marital conflicts (adjusted RR = 2.4, 95% CI: 1.5;3.9, p<0.001) or to serious difficulties at work (adjusted RR = 1.6, 95% CI :1.04;2.4, p = 0.031). An association was also found with the previous delivery of a child with a major or minor birth defect (adjusted RR = 2.0, 95% CI: 1.04;4.0, p = 0.038). Univariate analyses revealed a strong association with childhood adversity (parental rejection: RR = 1.8, 95% CI: 1.2;2.8, p = 0.0055 and family secrets: RR = 2.0, 95% CI: 1.2;3.1, p = 0.0046) and with lack of partner support (RR = 0.50, 95% CI: 0.30;0.84, p = 0.0086).

Conclusions/Significance

Our study identifies several risk factors that could easily be assessed in clinical practice. It draws attention to the impact of previously delivering a child with a birth defect. The association with childhood adversity warrants further study.

Experience of sexual violence among sexually experienced Japanese teenage girls and influencing factors

Aim:  The aim of the present study was to identify influencing factors for sexual violence in sexually experienced teenage girls. Methods:  Eighty sexually experienced teenage girls aged between 14 and 19 attending obstetrics and gynecology clinics in suburban Tokyo were selected as subjects. After completing a simple questionnaire on sexual behavior and lifestyle the subjects were interviewed using a semistructured interview technique. Logistic regression analysis was used to identify factors associated with sexual violence. Results:  Police and government statistics for rape, sexual and domestic violence in Japan are extremely low. However, the present study showed that 52.5% of subjects had been victims of sexual violence. Furthermore, of these, 69.0% had been forced to have sex with a partner and 64.3% had been raped by someone other than a partner. Factors influencing the risk of sexual violence were sexual behavior and attitudes towards sexuality and lifestyle. Having a sexually transmitted infection was not an influencing factor. Conclusions:  It is important to identify teenage girls attending obstetrics and gynecology clinics at risk of sexual violence and to teach them about the risks of sexual behavior associated with imbalances of power. Furthermore, it is essential to support victims of sexual violence to protect them from the recurrence of such abuse. (Reprod Med Biol 2008; 7: 181-187).

Risk factors for antenatal depression, postnatal depression and parenting stress

BACKGROUND

Given that the prevalence of antenatal and postnatal depression is high, with estimates around 13%, and the consequences serious, efforts have been made to identify risk factors to assist in prevention, identification and treatment. Most risk factors associated with postnatal depression have been well researched, whereas predictors of antenatal depression have been less researched. Risk factors associated with early parenting stress have not been widely researched, despite the strong link with depression. The aim of this study was to further elucidate which of some previously identified risk factors are most predictive of three outcome measures: antenatal depression, postnatal depression and parenting stress and to examine the relationship between them.

METHODS

Primipara and multiparae women were recruited antenatally from two major hoitals as part of the beyondblue National Postnatal Depression Program 1. In this subsidiary study, 367 women completed an additional large battery of validated questionnaires to identify risk factors in the antenatal period at 26-32 weeks gestation. A subsample of these women (N = 161) also completed questionnaires at 10-12 weeks postnatally. Depression level was measured by the Beck Depression Inventory (BDI).

RESULTS

Regression analyses identified significant risk factors for the three outcome measures. (1). Significant predictors for antenatal depression: low self-esteem, antenatal anxiety, low social support, negative cognitive style, major life events, low income and history of abuse. (2). Significant predictors for postnatal depression: antenatal depression and a history of depression while also controlling for concurrent parenting stress, which was a significant variable. Antenatal depression was identified as a mediator between seven of the risk factors and postnatal depression. (3). Postnatal depression was the only significant predictor for parenting stress and also acted as a mediator for other risk factors.

CONCLUSION

Risk factor profiles for antenatal depression, postnatal depression and parenting stress differ but are interrelated. Antenatal depression was the strongest predictor of postnatal depression, and in turn postnatal depression was the strongest predictor for parenting stress. These results provide clinical direction suggesting that early identification and treatment of perinatal depression is important.
