Risk factors for unfavorable pregnancy outcome in women with adverse childhood experiences

Aims: To explore the association between childhood sexual abuse (CSA), physical abuse, as well as other adverse childhood experiences (ACE), and different obstetrical risk factors/behaviors. Methods: In this cohort study, obstetrical risk factors and perinatal outcome in 85 women exposed to CSA were compared to 170 matched unexposed women. CSA, physical abuse, and ACE were explored by face-to-face interviews and by questionnaire. Data on perinatal outcome were extracted from medical charts. Fisher's exact, χ2-test, and multiple logistic regression were used for statistical analysis. Results: During pregnancy women with CSA experiences were significantly more often smoking (31.7%/9.4%; P<0.0001), had partners abusing drugs (10.6%/1.2%; P<0.0005), experienced physical (16.5%/0; P<0.0001), sexual (12.9%/0; P<0.0001), and emotional abuse (44.7%/1.7%; P<0.0001), reported depression (24.7%/1.8%; P<0.0001), and suicidal ideation (10.6%/0; P<0.0001) than women without CSA experiences. Differences in risk factors were more often correlated with physical than with sexual abuse during childhood. The probability for premature delivery was associated with CSA, physical abuse and ACE as well as with several of the risk factors investigated. Conclusion: Women with CSA, physical, and ACE present with a variety of abuse-associated obstetrical risk factors and an increased risk for premature delivery. Therefore, all types of abusive and other ACE should be considered in prenatal car

Prenatal care in adult women exposed to childhood sexual abuse

Aims: Several case reports show a negative impact of childhood sexual abuse (CSA) on prenatal care. The study aimed to systematically investigate this association in a larger study group. Methods: CSA was investigated by face-to-face interviews and by a modified questionnaire developed by Wyatt. All study participants completed a self-administered questionnaire designed to investigate the consequences of CSA on prenatal care during adulthood. Data from 85 women after CSA were compared to those of 170 matched women without such experiences. Results: Women exposed to CSA had fewer than five prenatal consultations more often than unexposed women (26%/7%; P<0.0001). Of the 85 women with a positive history for CSA, 9.4% had been asked for such antecedents, 36.5% had intense memories on original abuse situations during pregnancy, 56.6% mentioned specific consequences of CSA on prenatal care and 61.2% were satisfied with obstetrical support. Exposed women (62.4%) felt significantly less prepared for labor than unexposed women (75.9%) (P<0.0001). Conclusions: CSA experiences are associated with impaired prenatal care. These results underscore the compelling need to improve prenatal care in women exposed to CSA through better education of obstetricians regarding the effects of CSA and in their ability to provide empathetic professional suppor

Испытание технологии выравнивания профиля приемистости с применением модифицированного состава на основе полиакрилонитрила на нефтяном месторождении «S» (Томская область)

В работе рассматривается технология выравнивания профиля приемистости с применением модифицированного состава на основе полиакрилонитрила на одном из месторождений Западной Сибири. Используемый реагент предназначен для применения в технологиях повышения нефтеотдачи пласта с целью выравнивания профиля приёмистости в нагнетательных скважинах и ограничение водопритоков в добывающих скважинах. В работе проведен анализ эффективности рассматриваемой технологии.The technology of equalization of the injectivity profile using a modified composition based on polyacrylonitrile at one of the fields in Western Siberia is considered. The reagent used is intended for use in enhanced oil recovery technologies in order to equalize the injectivity profile in injection wells and to limit water inflows in producing wells. The analysis of the efficiency of the technology in question is conducted

Birth experiences in adult women with a history of childhood sexual abuse

Objective: Although childhood sexual abuse (CSA) may seriously impair childbirth experiences, few systematic evaluations on associations, mediating influences, risk and protective factors are available. As such information is mandatory to improve obstetric care, the present study aimed to provide such data. Methods: The study compared childbirth experiences from 85 women after CSA and at least one pregnancy resulting in a life birth with those from 170 control women matched for nationality, personal age and children's age. Trained specialists from support centers investigated CSA. Obstetrical data were collected from the official personal clinical record of each pregnancy (Mutterpass) and data on CSA as well as childbirth experiences were examined by questionnaires. Results: Childbirth was more often highly frightening (24.7 vs. 5.3%; p < 0.01) and a negative experience (40.7 vs. 19.6%, p < 0.01) in women with a history of CSA than in controls. Multivariate regression models support the hypothesis that at least part of this association was mediated by covariates (specifically, birth preparation classes, presence of a trusted person, participation in medical decision-making, pain relief, emergency during labor and extreme duration of labor), which represent important resources in improving obstetric care. In 41% of women with CSA, memories of traumatic experiences intruded during childbirth, whereas about 58% experienced dissociation. While dissociation may result in loss of contact with obstetric staff, it was also used to reduce labor pain. Conclusion: Childbirth following a history of CSA is associated with particular challenges. Creating a trusting environment by evaluating and integrating individual needs could ameliorate birth experiences

Breastfeeding in women having experienced childhood sexual abuse

BACKGROUND Childhood sexual abuse (CSA) can have a serious effect on general and obstetric health. Breastfeeding includes several triggers for memories of abuse experiences, which will likely influence decisions about breastfeeding and its implementation in daily life. This is important since breastfeeding improves maternal well-being and bonding with the child. Research aim: As breastfeeding strongly influences the long-term health of children, we investigated experiences with breastfeeding in women with a history of CSA. METHODS Data on breastfeeding were collected within a research project designed to compare labor and delivery experiences in women with a history of CSA to women without such antecedents. Data from 85 women having experienced CSA and 170 controls pair-matched for maternal age, children's age, and nationality were evaluated. The clinical record of pregnancy and a self-administered questionnaire were used to collect data. RESULTS Although the prevalence of breastfeeding was similar in women with and without CSA experiences (96.5% vs. 90.6%), women exposed to CSA more often described complications associated with breastfeeding (77.7% vs. 67.1%, p = .08). Mastitis (49.4% vs. 27.6%, p < .01) and pain (29.4% vs. 18.8%, p = .15) were reported significantly more often by women after CSA. For 20% of women after CSA, breastfeeding was a trigger for memories of CSA. Furthermore, 58% of women with CSA reported dissociation when breastfeeding. CONCLUSION In addition to the growing list of potential health consequences of CSA experience, this experience seems to be associated with an increased number of problems when breastfeeding. However, most women with a history of CSA intend to breastfeed despite particular challenges related to CSA. A support protocol tailored to the specific needs of these women during pregnancy and the lactation period may help to improve breastfeeding and the early mother-child relationship
