Pregnancy outcome following domestic violence in a Chinese community

The status of intimate partner violence against pregnant women in contemporary China: a scoping review

PURPOSE

This review explored the status of publications on intimate partner violence (IPV) against pregnant women in contemporary China.

METHODS

The PubMed, Cochrane Library, Embase, CINAHL, and PsycInfo databases were searched using the terms "IPV," "pregnant woman," "Chinese," and synonyms in English, along with related keywords for Chinese publications. All literature pertaining to IPV during pregnancy, conducted in China, and published between 1987 and September 2023 was included.

RESULTS

A total of 37 articles from 30 studies were selected. The prevalence of IPV during pregnancy ranged from 2.5% to 31.3%, with psychological violence being the most common form. Frequently identified risk factors included unintended pregnancy, poor family economic conditions, male partners engaging in health risk behaviors, poor employment status of women or their partners, low education levels among women, physical or mental health issues, strained couple relationships, and in-law conflicts. IPV during pregnancy primarily led to mental health problems for the victims and could result in adverse obstetric outcomes, as well as negative effects on the temperament and development of the offspring. Victims in China demonstrated a low willingness to seek help from professionals. Furthermore, relevant research in mainland China is scarce, with a limited number of studies and non-standardized research methodologies.

CONCLUSION

Future research should investigate IPV in pregnancy from various perspectives, identify factors unique to IPV during pregnancy, and focus on high-risk groups. Considering the conditions in China, there is a pressing need to increase public awareness of IPV and to investigate interventions aimed at addressing this issue.

High psychological stress levels related to delivery can increase the occurrence of postpartum mental disorders

Objective

The study sought to explore the relationship between high psychological stress levels related to delivery and postpartum mental disorders.

Methods

A total of 284 parturients were included in the study from July 2021 to January 2022. The stress level at 1 month postpartum was assessed by the Impact of Event Scale-Revised (IES-R). Parturients with an IES-R score ≤ 9 were included in the low psychological stress level group, and those with an IES-R score > 9 were included in the high psychological stress level group. The Edinburgh Postnatal Depression Scale (EPDS), Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ-70), Symptom Checklist-90 (SCL-90) and Mini-International Neuropsychiatric Interview (M.I.N.I.) were conducted at 42 ± 7 days postpartum to assess the mental health of parturients.The parturients' mental health after birth was assessed by the EPDS, UPPSAQ-70, and SCL-90. Semi-structured diagnostic interviews were conducted at 42 ± 7 days postpartum by using the M.I.N.I.

Results

The incidence rate of postpartum mental disorders was 20.42% (58/284), the incidence rates of postpartum depression, anxiety disorders, obsessive-compulsive disorder and posttraumatic stress disorder were 17.96% (51/284), 11.97% (34/284), 4.58% (13/284) and 1.41% (4/284), respectively, and the comorbidity rate was 58.62% (34/58). A history of mental disorders and pregnancy complications were risk factors for postpartum depression (p = 0.028, p = 0.040, respectively); a history of mental disorders, a lack of physical exercise, partner violence and pregnancy complications were risk factors for postpartum anxiety disorders (p = 0.003, p = 0.007, p = 0.031, p = 0.048, respectively); and the delivery of female infants was a risk factor for postpartum obsessive-compulsive disorder (p = 0.022).The risk of postpartum depression, anxiety disorders and obsessive-compulsive disorder was 9.125 times (95% CI = 3.900 ~ 21.349, p < 0.01), 7.310 times (95% CI = 2.588 ~ 20.649, p < 0.01) and 6.259 times (95% CI = 1.347 ~ 29.093, p < 0.01) higher in postpartum women with high psychological stress levels related to delivery than in those with low psychological stress levels, respectively.

Conclusion

The incidence of postpartum mental disorders is high and has a positive correlation with the level of psychological stress. This may lead to a new perspective of the effect of psychological stress on postpartum mental disorders and attract more attention to other mental disorders in addition to postpartum depression.

Maternal risk factors for low birth weight infants: A nested case-control study of rural areas in Kurdistan (western of Iran)

Infant mortality is among the most important indicators of health and development in global communities. One of the causes of neonatal mortality is low birth weight. This study aims at evaluating the risk factors for LBW in infants. This study was carried out using a nested case-control study in rural areas of Kurdistan province in Western Iran in 2015. The selection of case and control groups was based on the nesting using the risk set sampling approach. In total, 182 and 364 subjects were selected for the case group and the control group respectively. Data analysis was performed using the Stata-12 software with the point and spatial estimation of OR using the conditional logistic regression method. The multivariate logistic regression analysis performed shows that the maternal gestational age, the mother’s health history during pregnancy, any medication abuses by the mother, any mental stress during pregnancy, are LBW risk factors (P < 0.05). Prevention of LBW is possible by identifying effective factors and performing appropriate interventions in infants with low birth weight.

The specific and combined role of domestic violence and mental health disorders during pregnancy on new-born health

BACKGROUND

Addressing impaired foetal growth is recognized as a public health priority. Certain risk factors for this condition, such as poor nutritional status at birth, have been found to be highly correlated with poverty. However, the role of psychosocial factors, specifically the mother's mental health and exposure to violence during pregnancy, have yet to be further explored. Our objective was to determine if there is a measurable association between combined psychosocial factors, specifically domestic violence and mental disorders, and birth outcomes, specifically birth nutritional status and preterm delivery.

METHODS

We followed 775 women from an underserved, urban area, beginning their 28th week of gestation. Diagnostic interviews were performed to determine if any of the mothers had any of the following disorders: mood disorder, anxiety, obsessive-compulsive disorder (OCD), substance dependence, psychotic disorder, or anti-social personality disorder. Physical, psychological, and sexual domestic violence were also assessed.

RESULTS

Domestic violence and mental disorders were highly correlated in our sample. About 27.15% of the women in our study experienced domestic violence, and about 38.24% of them were diagnosed with mental disorders. The main association we found between combined psychosocial factors and neonate outcomes was between anxiety (IRR = 1.83; 95%CI = 1.06-3.17)/physical violence (IRR = 1.95; 95%CI = 1.11-3.42) and the rate of small-for-gestational age (SGA) in new-borns. More specifically, the combination of anxiety (beta = -0.48; 95%CI = -0.85/-0.10) and sexual violence (beta = -1.58; 95%CI = -2.61/-0.54) was also associated with birth length. Maternal risk behaviours such as smoking, drinking, inadequate prenatal care, and inadequate weight gain could not sufficiently explain these associations, suggesting that these psychosocial factors may be influencing underlying biological mechanisms.

CONCLUSION

Domestic violence against women and mental disorders amongst pregnant women are extremely prevalent in under-resourced, urban areas and ultimately, have detrimental effects on birth outcomes. It is imperative that actions be taken to prevent violence and improve mental health during pregnancy.

New challenges beyond nutrition: c-section, air pollution and domestic violence

The DOHaD research field has successfully associated adult non-communicable diseases with inadequate nutrition in early periods of life. More recently, different types of exposure have been linked with impaired developmental outcomes and later health consequences, such as cesarean section at delivery, air pollution and domestic violence during pregnancy. The aim of this work is to bring up this issue looking at the published evidence on these three highly prevalent hazards in Latin American countries.

Causes of trauma in pregnant women referred to shabih-khani maternity hospital in kashan

Background

Trauma occurs in 7% of pregnancies and is a major cause of morbidity and mortality in the mother and fetus.

Objectives

The present study was conducted in Kashan in 2009–2010 to evaluate the causes of trauma in pregnancy.

Patients and Methods

This descriptive study analyzed data from 32 pregnant women with trauma who were referred to the maternity hospital from 2009 to 2010. Data included age, gestational age, mother’s occupation, cause of trauma, maternal-fetal complications, gravidity, and parity. The diagnosis of maternal and fetal complications was based on clinical examinations by a gynecologist and results of blood tests, urine analysis tests, and sonography. Data were analyzed as frequency distributions.

Results

the causes of trauma included falling (9 cases (28.1%)), abdominal trauma (8 cases ( 25%)), spousal feud (3 cases (9.4%)), motorcycle accident (2 cases (6.25%)), car accident (2 cases (6.25%)), falling from a motorcycle (2 cases (6.25%)), falling or fainting resulting in head trauma (1 case (3.1%)), pain from crossing over a bump in the car (1 cases (3.1%)), and unspecified causes (4 cases (12.55%)). The causes of traumas occurred between 5 and 40 weeks of gestation. In 17.2% of the cases, trauma occurred prior to 20 weeks of gestation. However, there was no significant relationship between the cause of trauma and maternal age or gestational age. Vaginal bleeding and retroplacental clots were reported in 2 (6.25%) cases and 1 (3.1%) case, respectively.

Conclusions

Nearly half of the women presenting with trauma had experienced spousal feud or domestic violence; therefore, it is necessary to recognize spousal abuse and provide adequate support to traumatized pregnant women.

The use of psychosocial stress scales in preterm birth research

Psychosocial stress has been identified as a potential risk factor for preterm birth. However, an association has not been found consistently, and a consensus on the extent to which stress and preterm birth are linked is still lacking. A literature search was performed with a combination of keywords and MeSH terms to detect studies of psychosocial stress and preterm birth. Studies were included in the review if psychosocial stress was measured with a standardized, validated instrument and if the outcomes included either preterm birth or low birthweight. Within the 138 studies that met inclusion criteria, 85 different instruments were used. Measures that had been designed specifically for pregnancy were used infrequently, although scales were sometimes modified for the pregnant population. The many different measures that have been used may be a factor that accounts for the inconsistent associations that have been observed.

Pregnancy and Intimate Partner Violence: Risk Factors, Severity, and Health Effects

The current study compares female victims of intimate partner violence (IPV) who were and were not victimized during pregnancy. Victims of pregnancy violence are more likely to report having experienced all forms of violence, particularly severe forms, and have higher odds of experiencing several postviolence indicators of severity and adverse health consequences. The significance of predictors disappears in a post hoc analysis controlling for proxies of battering behavior (i.e., repeated and severe violence), suggesting that victims who experience violence during pregnancy may be more likely to be in a current intimate relationship with an abuser who inflicts repeated and severe IPV.

Maternal exposure to domestic violence and pregnancy and birth outcomes: a systematic review and meta-analyses

BACKGROUND

Pregnant women who experience domestic violence are at increased risk of adverse outcomes in addition to the risks to themselves. Inadequate prenatal care, higher incidences of high-risk behaviors, direct physical trauma, stress, and neglect are postulated mechanisms. Our objective was to systematically review birth outcomes among women who experienced domestic violence.

METHODS

Medline, Embase, CINAHL, and bibliographies of identified articles were searched for English language studies. Studies reporting rates of low birth weight, preterm birth, small for gestational age births, birth weight, or gestational age at birth were included. Study quality was assessed for selection, exposure assessment, confounder adjustment, analyses, outcomes assessment, and attrition biases. Unadjusted and adjusted data from included studies were extracted by two reviewers. Summary odds ratio (OR) and confidence intervals (CI) were calculated using the random effects model. Population-attributable risk was calculated.

RESULTS

Thirty studies of low to moderate risk of biases were included. Low birth weight (adjusted OR 1.53, 95% CI 1.28-1.82) and preterm births (adjusted OR 1.46, 95% CI 1.27-1.67) were increased among women exposed to domestic violence. As the prevalence of reported domestic violence during pregnancy was low, the population-attributable risk was low. Prospective cohort studies provided robust and consistent results.

CONCLUSIONS

Maternal exposure to domestic violence was associated with significantly increased risk of low birth weight and preterm birth. Underreporting of domestic violence is hypothesized. Effective programs to identify violence and intervene during pregnancy are essential.

Violence during pregnancy and newborn outcomes: a cohort study in a disadvantaged population in Brazil

BACKGROUND

Violence against pregnant women is an increasing public health concern. The purpose of this study is to estimate the prevalence of violence during pregnancy, to identify characteristics associated and to assess the impact of violence on newborn outcomes.

METHODS

Prospective cohort study of 652 pregnant women attending primary care clinics in Southern Brazil, from June 2006 to September 2007. Women with gestational age ranging from 16th and 36th were enrolled and their exposure to violence and mental disorder was assessed. After the birth they were contacted by telephone when information on obstetric and neonatal outcomes was obtained.

RESULTS

Any violence during current pregnancy was reported by 18.3% [95% confidence interval (CI) 15.3-21.4%] participants, 15.0% (95% CI 12.3-17.8%) psychological violence, 6% (95% CI 4.2-7.8%) physical violence and 3% (0-0.5%) sexual violence. These women were more often of low income, did not work or study and had inadequate prenatal care and pregnancy weight gain. There was a statistically significant crude association between exposure to physical and psychological violence [relative risk (RR) 3.21 (1.51-6.80)]. After adjustment for family income, number of prenatal visits, length of gestation and gestational weight gain, the effect size decreased, but remained statistically significant (RR 2.18; 95% CI 1.16-4.08%).

CONCLUSION

In disadvantaged settings in Brazil, violence in pregnancy is frequent; it is associated with inadequate maternal weight gain during pregnancy and prenatal care, and increases risk of low birth-weight. Thus, violence in pregnancy imposes a challenge to effective prenatal care delivery with potential benefits to the mother and her baby.

Prevalence, types, and pattern of intimate partner violence among pregnant women in Lima, Peru

This study assesses the prevalence, types, and pattern of intimate partner violence (IPV) during lifetime and current pregnancy for 2,392 women in Lima, Peru. The reported lifetime prevalence of any IPV (physical, sexual, or emotional) is 45.1%. For women who experienced abuse, the prevalence of lifetime physical, emotional, and sexual IPV is 34.2%, 28.4%, and 8.7%, respectively. Older (>/= 30 years), unmarried, employed, and economically disadvantaged women and those with little education are more likely to experience lifetime and pregnancy IPV. Efforts at universal antepartum IPV screening and appropriate interventions are needed to reduce the burden of violence experienced by pregnant women.

The impact of maternal experience of violence and common mental disorders on neonatal outcomes: a survey of adolescent mothers in Sao Paulo, Brazil

BACKGROUND

Both violence and depression during pregnancy have been linked to adverse neonatal outcomes, particularly low birth weight. The aim of this study was to investigate the independent and interactive effects of these maternal exposures upon neonatal outcomes among pregnant adolescents in a disadvantaged population from Sao Paulo, Brazil.

METHODS

930 consecutive pregnant teenagers, admitted for delivery were recruited. Violence was assessed using the Californian Perinatal Assessment. Mental illness was measured using the Composite International Diagnostic Interview (CIDI). Apgar scores of newborns were estimated and their weight measured.

RESULTS

21.9% of mothers reported lifetime violence (2% during pregnancy) and 24.3% had a common mental disorder in the past 12 months. The exposures were correlated and each was associated with low education. Lifetime violence was strongly associated with Common Mental Disorders. Violence during pregnancy (PR = 2.59(1.05-6.40) and threat of physical violence (PR = 1.86(1.03-3.35) and any common mental disorders (PR = 2.09 (1.21-3.63) (as well as depression, anxiety and PTSD separately) were independently associated with low birth weight.

CONCLUSION

Efforts to improve neonatal outcomes in low income countries may be neglecting two important independent, but correlated risk factors: maternal experience of violence and common mental disorder.

Effects of domestic violence on perinatal and early-childhood mortality: evidence from north India

OBJECTIVE

We examined the effect of physical violence during pregnancy on perinatal and early-childhood mortality.

METHODS

We estimated the prevalence of domestic violence during pregnancy among a population-based sample of 2199 women in Uttar Pradesh, India. We used a survival regression model to examine the risks for perinatal, neonatal, postneonatal, and early-childhood (aged 1-3 years) mortality by mother's exposure to domestic violence, after we controlled for other sociodemographic and maternal health behavior risk factors.

RESULTS

Eighteen percent of the women in our study experienced domestic violence during their last pregnancy. After we adjusted for other risk factors, births among mothers who had experienced domestic violence had risks for perinatal and neonatal mortality that were 2.59 (95% confidence interval [CI]=1.35, 4.95) and 2.37 (95% CI=1.21, 4.62) times higher, respectively, than births among mothers who had not experienced violence. We found no significant associations between domestic violence and either postneonatal or early-childhood mortality.

CONCLUSIONS

Domestic violence is a significant risk factor for perinatal and neonatal mortality.

Quality of life of victims of intimate partner violence

OBJECTIVE

To evaluate the impact of intimate partner violence on the quality of life in Obstetric/Gynecological (OBGYN) patients.

METHOD

A total of 1614 OBGYN patients were classified into four groups (Group 1: requesting termination of pregnancy, n=300; Group 2: infertility patients, n=500; Group 3: other general gynecological patients, n=300; Group 4: obstetric patients, n=514) were successfully interviewed in the absence of their male partners, using a structured questionnaire modified from the Abuse Assessment Screen Questionnaire. Those who reported ever having been abused, together with an equal number of non-abused women as controls, were asked to complete the World Health Organization Quality of Life Measure - Abbreviated version (Hong Kong) Questionnaire.

RESULTS

The overall lifetime prevalence of intimate partner violence was 7.2%, with the lifetime prevalence being 12.7%, 1.8%, 4.7%, and 10.9% respectively in Groups 1-4. The mean quality of life domain scores among the abused victims were significantly lower in the physical health domain, social relationship domain, environment domain and psychological health domain.

CONCLUSION

The baseline quality of life of the victims of intimate partner violence is significantly impaired compared with the non-abused controls.

Does pregnancy provide immunity from intimate partner abuse among Hong Kong Chinese women?

The level of intimate partner abuse that occurs in Hong Kong Chinese families and the type, nature, and severity of abuse are primary concerns of those who are engaged in efforts to reduce and control abuse. A total of 1200 postnatal women were recruited at a university-affiliated regional public hospital to participate in a study with a retrospective explorative comparative design. The women were identified as abused or non-abused using the Abuse Assessment Screen Questionnaire (AAS). The type, nature, and profile of intimate partner abuse were investigated by using the Revised Conflict Tactics Scale (CTS-2). The vulnerable factors and predictors of abuse during pregnancy were explored in their demographic, psycho-socio-economic-cultural, and obstetric aspects. Analysis of the data indicated that 134 (11.2%) of the women had experienced abuse during pregnancy. The majority of this abuse took the form of psychological aggression (79.1%), and nearly half (49.3%) of the abused women had experienced sexual abuse. The husband was the perpetrator in the majority of cases (82.1%). Women who were younger, born in Hong Kong, single or cohabiting, had poor socio-economic status, a poor partner relationship, and an unplanned pregnancy were more likely to be abused based on multiple logistic regression models of various nature and type of abuse (p<0.05). The findings provide fundamental information for the prevention of intimate partner abuse among the Hong Kong population. The implications, limitations, and future research are discussed.

Partner violence during pregnancy and risk of adverse pregnancy outcomes

The purpose of this cross-sectional study was to investigate the association between partner physical or emotional abuse during pregnancy and pregnancy outcomes including perinatal death, low birthweight and preterm delivery. Women, aged 18-65, who attended one of two large primary care practices from 1997-98 were recruited for this study. Ever pregnant women were asked the frequency of abuse during each pregnancy and details of the pregnancy outcomes. Information regarding abuse during pregnancy and pregnancy outcomes was available for 755 women surveyed who reported a live birth or late fetal death, 14.7% indicated that an intimate partner was violent or abusive toward them during a pregnancy (274 of 1862 pregnancies). Abuse during pregnancy was significantly associated with an increased risk of perinatal death (adjusted relative risk [aRR] = 2.1, 95% confidence interval [CI] 1.3, 3.4) and, among live births, with preterm low birthweight (aRR = 2.4; 95% CI 1.5, 4.0) and term low birthweight (aRR = 1.9; 95% CI 1.0, 3.4). Greater abuse frequency was associated with increased risk. Abuse during pregnancy was associated with perinatal deaths and preterm low birthweight deliveries.

Domestic violence and postnatal depression in a Chinese community

OBJECTIVES

To study the relationship between domestic violence and postnatal blues/depression in a Chinese community.

METHODS

This was a prospective cohort study on 838 women after delivery in a local university teaching hospital. Between October, 2000 and February, 2001, all Chinese speaking women after delivery were invited to be interviewed by a designated research nurse using the Abuse Assessment Screen (AAS) to detect the incidence of domestic violence, the nature of violence and the perpetrator of abuse. Demographic data, pregnancy outcome, Stein's Daily Scoring System (SDSS) scores on day 2 or 3 postdelivery, Edinburgh Postnatal Depression Scale (EPDS) scores on day 2 or 3 postdelivery, 1-2 days after discharge from hospital and at 6 weeks postdelivery were compared between the abused and non-abused groups using Student's t-test, chi(2)-test and Fisher's exact test as appropriate.

RESULTS

A total of 139 women (16.6%) had been abused in the last year (the abused group). Of these, 87 (10.4%) had been abused during the current pregnancy. The nature of abuse was mainly verbal. Fourteen women (1.7%) had been sexually abused in the last year. The husband/boyfriend, mother-in-law and employer/colleague were the most common perpetrators of abuse. Socio-demographic factors did not differ between the two groups except that pregnancy was more likely to be unplanned in the abused group (P=0.002). The pregnancy outcome did not differ. However, the abused group had significantly higher SDSS and EPDS scores at all stages of screening (P=0.003, P=0.000, P=0.010 and P=0.001, respectively).

CONCLUSION

The findings supported our hypothesis that the effect of domestic violence on Chinese pregnant women is mainly on their psychological well-being.
