Experiences with use of technology and telehealth among women with perinatal depression.

BACKGROUND: Perinatal depression (PD) affects 10-20% of childbearing women. Telehealth is increasingly utilized for mental health services to increase access to care and overcome COVID-19 pandemic barriers. Women's perspectives on telehealth services for PD is unknown, however. This study's primary objective was to obtain the perspectives of women who participated in an 8-week group videoconference intervention for PD symptoms, including how technology impacted their experience. METHODS: We utilized theoretical sampling and included perinatal women who had completed the 8-week mindfulness-based cognitive-behavioral intervention group. Semi-structured focus groups with four to six women were conducted on a videoconference platform. Primary analysis used grounded theory and a secondary analysis used qualitative description and was conducted by two coding teams. The teams collaborated on the final themes across the analyses. RESULTS: Three groups, with a total of 17 participants were conducted. Composition consisted of seven postpartum and ten pregnant women from the 47 total participants. Identified core themes regarding their experiences of the videoconference intervention were: positive experiences, negative experiences, suggestions and ideas, and screening and communication. CONCLUSION: This study provides growing evidence informed by perinatal women of positive experiences with engagement in a videoconference intervention for PD. Telehealth may be a reasonable and acceptable platform to increase access and retention for mental health services in childbearing women. Further, this pilot work showcases videoconferencing delivery for a wide range of effective and affordable mental health services in low-resource communities.

Implementation and Outcomes of a Telehealth Neonatology Program in a Single Healthcare System.

Background: Intermountain Healthcare, an early adopter and champion for newborn video-assisted resuscitation (VAR), identified a reduction in facility-level transfers and an estimated savings of $1. 2 million in potentially avoided transfers in a 2018 study. This study was conducted to increase understanding of VAR at the individual, newborn level. Study Aim: To compare transfers to a newborn intensive care unit (NICU), length of stay (LOS), and days of life on oxygen between newborns managed by neonatal VAR and those receiving standard care (SC). Methods: This retrospective, nonequivalent group study includes infants born in an Intermountain hospital between 2013 and 2017, 34 weeks gestation or greater, and requiring oxygen support in the first 15 minutes of life. Data came from billing and clinical records from Intermountain's enterprise data warehouse and chart reviews. We used logistic regression to estimate neonatal VAR's impact on transfers. Negative binomial regression estimated the impact on LOS and days of life on supplemental oxygen. Results: The VAR intervention was used in 46.2 percent of post-implementation cases and is associated with (1) a 12 percentage points reduction in the transfer rate, p = 0.02, (2) a reduction in spoke hospital (SH) LOS of 8.33 h (p < 0.01) for all transfers; (3) a reduction in SH LOS of 2.21 h (p < 0.01) for newborns transferred within 24 h; (4) a reduction in SH LOS of 17.85 h (p = 0.06) among non-transferred newborns; (5) a reduction in days of life on supplemental oxygen of 1.4 days (p = 0.08) among all transferred newborns, and (6) a reduction in days of life on supplemental oxygen of 0.41 days (p = 0.04) among non-transferred newborns. Conclusion: This study provides evidence that neonatal VAR improves care quality and increases local hospitals' capabilities to keep patients close to home. There is an ongoing demand for support to rural and community hospitals for urgent newborn resuscitations, and complex, mandatory NICU transfers. Efforts may be necessary to encourage neonatal VAR since the intervention was only used in 46.2 percent of this study's potential cases. Additional work is needed to understand the short- and long-term impacts of Neonatal VAR on health outcomes.

Scoping Review of the Associations Between Perinatal Substance Use and Perinatal Depression and Anxiety.

OBJECTIVE: To evaluate published literature on the associations between perinatal substance use (PSU), perinatal depression and anxiety (PDA), and known maternal-newborn outcomes. DATA SOURCES: We conducted a systematic search of health-related databases, including PubMed, CINAHL, MEDLINE, and Embase. Search terms included maternal mental health, substance use, postpartum, opioid, alcohol, methamphetamine, addiction, dependence, pregnancy, depression, and anxiety. STUDY SELECTION: We included English-language, peer-reviewed reports of primary research and systematic reviews that were published between 2010 and 2020 and focused on PSU and PDA. We excluded commentaries, nonsystematic reviews, and articles on maternal mental health other than PDA. Fourteen of 379 articles met the inclusion criteria. DATA EXTRACTION: We used the Joanna Briggs Institute Review Guidelines to guide extraction of the following data: author(s), year of publication, type of study, country of origin, study sample, targeted substance(s), mental health, key findings, and recommendation(s). DATA SYNTHESIS: In studies of PSU, researchers identified a strong association with PDA. Likewise, researchers investigating PDA found a strong association with PSU. Findings from these articles suggest an increasing risk for PSU with increasing severity of PDA, depending on the specific substances of use. Findings also indicated that women with polysubstance use have greater odds for comorbid perinatal mental health conditions. A relationship between PSU and PDA and adverse newborn outcomes, such as low birth weight, was found. CONCLUSION: There is a paucity of published research on co-occurring PSU and PDA. However, polysubstance use appears to be associated with the greatest risk for PDA. It is essential to address PSU and PDA together to better understand the effects on maternal and infant outcomes.

A Group Videoconference Intervention for Reducing Perinatal Depressive Symptoms: A Telehealth Pilot Study.

INTRODUCTION: Perinatal depression occurs in 12% to 18% of childbearing women. Telehealth is a promising platform for delivering perinatal mental health care, particularly during a pandemic when in-person services have been significantly curtailed. However, there is little research to document the feasibility of telehealth to address perinatal depression. This pilot study evaluated the feasibility and preliminary results of an 8-week facilitated group videoconference intervention. METHODS: The study enrolled pregnant and postpartum women into an 8-week group mindfulness-based cognitive behavioral intervention, delivered via videoconference platform. Women receiving care at outpatient clinics who either screened positive for perinatal depression symptoms or had risk factors predictive of perinatal depression were invited to participate. Women attended weekly one-hour group sessions using their own electronic device and completed the Edinburgh Postnatal Depression Scale (EPDS) at several time points. Session attendance and survey completion rates were evaluated. RESULTS: A total of 47 women enrolled (8 postpartum; 39 prenatal) into groups of 4 to 6. Twenty-four (51.1%) women were currently experiencing mild to moderate perinatal depression symptoms (EPDS score of 10-20), whereas 23 (48.9%) women had EPDS scores less than 10 but were at high risk for developing perinatal depression due to health history and significant life events. Seventy percent of women attended at least 5 of the 8 sessions. Trajectories of EPDS measures were promising (ie, downward among those with current perinatal depression symptoms and stable among those at high risk for developing perinatal depression). DISCUSSION: These observational results are promising, suggesting further study of effectiveness for women with symptoms of perinatal depression, as well as for women at high risk for developing perinatal depression. Randomized trials could evaluate the effectiveness of the intervention, compared with standard of care approaches. Telehealth interventions can be tailored to meet the needs of different communities, and increase access to care, regardless of where women live or inability to receive in-person services.

The Use of a Game-Based Decision Aid to Educate Pregnant Women about Prenatal Screening: A Randomized Controlled Study.

PURPOSE: This project developed and evaluated the efficacy of a game decision aid among pregnant women about prenatal screening in a randomized controlled study. STUDY DESIGN: Participants were recruited from an obstetric clinic of an academic urban medical center and randomized (n = 73) to one of two study groups: the control group (n = 39) that used a brochure or the intervention group (n = 34) that also used a game decision aid. RESULT: Participants who played the game had higher knowledge scores (m = 21.41, standard deviation [SD] = 1.74) than participants in the control group (m = 19.59; SD = 3.31), p = 0.004. The median time of game playing was 6:43 minutes (range: 2:17-16:44). The groups were similar in frequency of completing screening after the study, control = 6 (15%) versus intervention = 11 (32%), p = 0.087. However, the more interaction with the game resulted in more positive attitudes toward screening. CONCLUSION: The addition of a game decision aid was effective in educating pregnant women about prenatal screening. As other genetic testing decisions continue to increase within clinical care, game-based decision tools may be a constructive method of informed decision-making.

Migraines in Women: Current Evidence for Management of Episodic and Chronic Migraines.

Migraine headache is a disabling brain disorder that affects millions of women in the United States. Many migraine sufferers are undertreated. Both inadequate treatment and overuse of abortive migraine medication can contribute to progression from episodic to chronic migraine disorders. A significant number of migraine headaches or severity of episodic migraine headaches warrants treatment with prophylactic medications for prevention. This clinical update reviews the pathophysiology and diagnosis of migraine headaches in women, discusses the efficacy of abortive and chronic pharmacologic treatment, and examines strategies to prevent progression from episodic migraine to chronic migraine. A discussion of treatment during pregnancy and lactation is included.

Selective Serotonin Reuptake Inhibitors as First-Line Antidepressant Therapy for Perinatal Depression.

One in 7 women experience depression during the prenatal and/or postpartum period. Nonpharmacologic approaches are known to be as effective as pharmacologic therapies for mild to moderate depression. However, for women who suffer from moderate to severe depression, antidepressant therapy may be the best option, in combination with nonpharmacologic approaches. Considering the substantial negative impact of untreated perinatal depression, providers of prenatal care need to be prepared to diagnose depression, prescribe first-line antidepressants, and refer to other professionals. The purpose of this article is to assist providers to select the safest, most effective selective serotonin reuptake inhibitor (SSRI) as the first-line antidepressant during pregnancy and lactation. Information about side effects, adverse effects, contraindications, and clinical considerations associated with the use of SSRIs is provided. A brief discussion of nonpharmacologic therapies is provided but is not the focus of this article.

Using Simulation in Nursing PhD Education: Facilitating Application of Responsible Conduct of Research Principles.

Simulation is a standard clinical nursing educational approach; however, simulation is rarely used in nonclinical nursing education. In doctor of philosophy (PhD) programs, ethical content about responsible conduct of research (RCR) is traditionally didactic, presented early in the program of study. Ethics content merits review before students begin the dissertation phase; thus, the purpose of this project was to design and implement simulated scenarios to help students apply RCR principles prior to beginning independent research. Two scenarios were developed: (a) a potential protocol change discussed in a research team meeting and (b) an in-home data collection experience with an elderly participant and her daughter. Actors were trained faculty volunteers, playing roles outside their usual academic positions. Faculty facilitated scenarios by posing questions as cues related to desired learning outcomes as scenarios unfolded. Eleven nursing PhD students and 6 faculty participated. Debriefing facilitated discussion of RCR principles, common research quandaries, and suggested scenario revisions. Faculty, expert observation, and video-review showed that younger and less experienced students tried to give the "right" answer rather than implement RCR appropriate solutions. Students with more clinical experience had difficulty adopting the less familiar researcher role. Overall, simulation is a novel and useful way to enhance RCR content in PhD programs.

Identifying and Addressing Problems for Student Progression in Midwifery Clinical Education.

Identifying challenges to progression for a health care profession student who is not meeting expectations in a busy clinical practice can be challenging yet can lead to assisting the student toward success. Preceptor preparation includes acquiring knowledge about the student's education program, understanding federal regulations designed to protect students, gathering background information about a student, learning to provide feedback, structuring the clinical experience, and completing student evaluations. Students in health care professions may have difficulties with cognitive, affective, or psychomotor learning, and the clinical preceptor can identify problems for student progression within these learning domains. Subsequently, specific solutions that are tailored to the individual student's needs can be developed, implemented, and evaluated. A structured evaluation of the student's performance by the clinical preceptor, in accordance with the education program's parameters, is essential. Through a structured process, preceptors can assist many students to achieve success, in spite of challenges. This article describes how the preceptor can prepare, identify the type(s) of problem(s), and develop learning solutions for students who are experiencing difficulties in clinical settings.

Creatine as a Novel Treatment for Depression in Females Using Methamphetamine: A Pilot Study.

OBJECTIVE: Depression among methamphetamine users is more prevalent in females than males, but gender-specific treatment options for this comorbidity have not been described. Reduced brain phosphocreatine levels have been shown to be lower in female methamphetamine users compared to males, and, of relevance, studies have demonstrated an association between treatment-resistant depression and reduced brain phosphocreatine concentrations. The nutritional supplement creatine monohydrate has been reported to reduce symptoms of depression in female adolescents and adults taking antidepressants, as well as to increase brain phosphocreatine in healthy volunteers. Therefore, the purpose of this pilot study was to investigate creatine monohydrate as a treatment for depression in female methamphetamine users. METHODS: Fourteen females with depression and comorbid methamphetamine dependence were enrolled in an 8-week open label trial of 5 g of daily creatine monohydrate and of these 14, 11 females completed the study. Depression was measured using the Hamilton Depression Rating Scale (HAMD) and brain phosphocreatine levels were measured using phosphorus magnetic resonance spectroscopy pre- and post-creatine treatment. Secondary outcome measures included anxiety symptoms, measured with the Beck Anxiety Inventory (BAI), as well as methamphetamine use, monitored by twice weekly urine drug screens and self-reported use. RESULTS: The results of a linear mixed effects repeated measures model showed significantly reduced HAMD and BAI scores as early as week 2 when compared to baseline scores. This improvement was maintained through study completion. Brain phosphocreatine concentrations were higher at the second phosphorus magnetic resonance spectroscopy scan compared to the baseline scan; Mbaseline = 0.223 (SD = 0.013) vs. Mpost-treatment = 0.233 (SD = 0.009), t (9) = 2.905, p <.01, suggesting that creatine increased phosphocreatine levels. Also, a reduction in methamphetamine positive urine drug screens of greater than 50% was observed by week 6. Finally, creatine was well tolerated and adverse events that were related to gastrointestinal symptoms and muscle cramping were determined as possibly related to creatine. CONCLUSIONS: The current study suggests that creatine treatment may be a promising therapeutic approach for females with depression and comorbid methamphetamine dependence. This study is registered on clinicaltrials.gov (NCT01514630).

Duration of Maternal Stress and Depression: Predictors of Newborn Admission to Neonatal Intensive Care Unit and Postpartum Depression.

BACKGROUND: Maternal psychosocial factors contribute to adverse pregnancy outcome, but very few studies have assessed associations of duration and experiences of stress, depression, and intimate partner violence (IPV) with maternal and newborn outcomes. OBJECTIVES: It was hypothesized that duration and level of maternal stress, depression, and IPV would predict increased risk of adverse maternal/newborn outcomes. METHODS: A secondary data analysis of a population-based data set collected by the Utah Department of Health Pregnancy Risk Assessment and Monitoring System and birth certificates for 4682 live births was conducted, reflecting a total population size of 143,373 live births in 2009-2011. Exposures of interest were experiences and duration of maternal stress, depression, and IPV before and during pregnancy. Outcomes were gestational age, birth weight, newborn admission to the neonatal intensive care unit (NICU), and postpartum depression (PPD) symptoms and diagnosis. RESULTS: After controlling for maternal demographics, body mass index, and smoking, women with greater duration of depression before and during pregnancy showed an increase in admission of their newborn to NICU (adjusted odds ratios [aORs] = 1.66-2.48, p < .001), PPD symptoms (aORs = 3.94-9.13, p < .001), and diagnosis of PPD (aORs = 7.72-59.60, p < .001). More kinds of experiences of maternal stress were associated with higher odds of PPD symptoms (aORs = 1.34-5.51, p < .001), but not PPD diagnosis or NICU admissions. DISCUSSION: Longer lasting maternal depression and stress are associated with poorer outcomes for mothers and newborns. Future prospective studies should evaluate the usefulness of preconception and continuous prenatal risk identification of maternal depression and stress. This would facilitate timely psychosocial interventions as an approach to improving maternal/newborn outcomes for these higher risk women.

Exploring the Psychosocial Predictors of Gestational Diabetes and Birth Weight.

OBJECTIVE: To determine the best sociodemographic and behavioral predictors for gestational diabetes mellitus (GDM) and birth weight (BW) and whether stress, depression, or abuse influences GDM and BW after controlling for sociodemographic variables. DESIGN: Retrospective correlational. SETTING: Utah Pregnancy Risk Monitoring System and birth certificate data. PARTICIPANTS: We analyzed data from the birth certificates of 4,682 women with live births between 2009 and 2011 in Utah. During that time, a total of 143,373 live births occurred in the state. Data were predominantly from non-Hispanic White, married, or partnered women with average age of 27.5 years and average body mass index (BMI) of 25.1. METHODS: Stress, cumulative depression, and abuse were operationalized based on previous analysis, and control and covariate data (e.g., age, BMI, race, ethnicity, education, marital status) were collected. Bivariate analysis was used to identify associations between variables, and a hierarchical stepwise logistical regression was conducted to identify best predictors of GDM and BW. RESULTS: We did not find that cumulative depression, stress, or abuse was a predictor of GDM, and only cumulative stress was a predictor of BW. More incidences of GDM were observed in women who were poor, older, less educated, non-White, obese, or experienced depression during pregnancy. CONCLUSION: Unlike depression or abuse, stress is often overlooked by providers. This finding represents an unmet opportunity for nurses to screen for and assist women with stressors to positively affect birth weight.

The Utility of Magnetic Resonance Spectroscopy for Understanding Substance Use Disorders: A Systematic Review of the Literature.

The aim of this article is to present a systematic review of magnetic resonance spectroscopy (MRS) studies of substance use disorders. As a noninvasive and nonionizing imaging technique, MRS is being widely used in substance abuse research to evaluate the effects substances of abuse have on brain chemistry. Nearly 40 peer-reviewed research articles that focused on the utility of MRS in alcohol, methamphetamine, 3,4-methylenedioxymethamphetamine, cocaine, opiates, opioids, marijuana, and nicotine use disorders were reviewed. Findings indicate inconsistencies with respect to alterations in brain chemistry within each substance of abuse, and the most consistent finding across substances was decreased N-acetylaspartate and choline levels with chronic alcohol, methamphetamine, and nicotine use. Variation in the brain regions studied, imaging technique, as well as small sample sizes might explain the discrepancies in findings within each substance. Future well-designed MRS studies offer promise in examining novel treatment approaches in substance use disorders.

The Fascinating and Complex Role of the Placenta in Pregnancy and Fetal Well-being.

Existing evidence implicates the placenta as the origin of some common pregnancy complications. Moreover, some maternal conditions, such as inadequate nutrition, diabetes, and obesity, are known to adversely affect placental function, with subsequent negative impact on the fetus and newborn. The placenta may also contribute to fetal programming with health consequences into adulthood, such as cardiovascular, metabolic, and mental health disorders. There is evidence that altered placental development, specifically impaired trophoblast invasion and spiral artery remodeling in the first trimester, is the origin of preeclampsia. Prenatal care providers who understand the relationships between placental health and maternal-newborn health can better inform and guide women to optimize health early in pregnancy and prior to conception. This article reviews the current understanding of placental function; placental contributions to normal fetal brain development and timing of birth; and impact of maternal nutrition, obesity, and diabetes on the placenta.

An update on current prenatal testing options: first trimester and noninvasive prenatal testing.

Prenatal genetic testing is rapidly evolving and requires that prenatal care providers stay up-to-date with accurate, evidence-based knowledge. Noninvasive prenatal testing (NIPT), first trimester maternal serum markers, and fetal nuchal translucency are the most recently developed screening tests added to the testing repertoire for detection of chromosomal disorders such as trisomy 21 (Down syndrome). NIPT is a new, highly accurate technique that uses maternal serum and is rapidly being introduced as a first trimester screening tool and increasingly being requested by pregnant women. The American College of Obstetricians and Gynecologists recommends that all pregnant women be offered first and second trimester screening options, regardless of risk status, but does not yet recommend NIPT. It is important for prenatal care providers to be aware of and understand these testing options in order to assist women and their families in making well-informed decisions during pregnancy. The purpose of this article is to update midwives and other prenatal care providers on the current prenatal genetic testing options available and how to appropriately offer and discuss them with their clients. We discuss how these tests work; what to do with the results; and most importantly, how to support and communicate accurate information to women and families as they navigate through an increasingly complicated array of testing choices.

Psychological distress and SSRI use predict variation in inflammatory cytokines during pregnancy.

Evidence supports the premise that maternal psychological distress adversely affects pregnancy outcomes and that inflammatory markers and placentally-produced corticotrophin-releasing hormone (pCRH) are likely mediating factors. The primary aim of the study was to explore the associations between maternal psychological distress, use of selective serotonin re-uptake inhibitors, pCRH, and maternal plasma inflammatory markers during pregnancy. Measures of maternal plasma pCRH, Interleukins-1, 6, & 10, C-Reactive Protein, Macrophage Migration Inhibitory Factor, and Tumor Necrosis Factor-α were completed in 100 pregnant women. Measures of depression, anxiety, and perceived stress were completed, as well as collection of demographic/behavioral data, e.g. use of selective serotonin re-uptake inhibitors (SSRIs). Significant correlations were found at 14-20 weeks gestation between IL-6 & 10, and depression, anxiety, and perceived stress. Also at 14 - 20 weeks gestation, IL10 levels were significantly lower in women with 4th quartile pCRH levels and IL1ß, IL6, and IL10 were significantly lower among women who took an SSRI during pregnancy. After controlling for maternal age, BMI, pCRH level, and SSRI use, psychological distress remained to explain variation in maternal inflammatory markers. These results might suggest that future research should focus on whether depression and anxiety are effectively being treated during pregnancy, and how such a scenario might contribute to an immune system pathway to poor pregnancy outcome.

Maternal corticotropin-releasing hormone and the use of selective serotonin reuptake inhibitors independently predict the occurrence of preterm birth.

INTRODUCTION: Studies support the premise that chronic maternal stress may trigger a premature sequence of physiologic events ending in preterm birth (PTB). Furthermore, chronic stress is highly correlated with depression and anxiety, which also are associated with PTB. However, some studies report that medication status rather than depression and/or anxiety may reflect the risk for PTB. Although the purpose of this small, preliminary study was to evaluate the association between chronic maternal stress and PTB, this report focuses on the unexpected finding of the association between maternal use of selective serotonin reuptake inhibitors (SSRIs) and PTB. METHODS: A prospective cohort study of 100 pregnant women included measures of contributors to chronic maternal stress and corticotropin-releasing hormone (CRH). Demographic and behavioral data included smoking, substance use, and use of medications for depression and anxiety. RESULTS: Pregnant women who used SSRIs to treat depression and/or anxiety were nearly 12 times more likely to give birth before term when compared with women who did not use these medications. Women with CRH levels in the fourth quartile were 6 times more likely to give birth before term when compared with women whose CRH levels were in the lower 3 quartiles. No associations were found between SSRI use and CRH levels. DISCUSSION: Associations between PTB and maternal use of SSRIs are not understood. It is important not to alter current approaches to the treatment of depression and anxiety without thorough discussion with women regarding the potential benefits and harms of various treatment options.

Perinatal genomics: Current research on genetic contributions to preterm birth and placental phenotype.

Significant maternal, fetal, and newborn morbidity and mortality can be attributed to complications of pregnancy. There are direct links between perinatal complications and poor fetal/newborn development and impaired cognitive function, as well as fetal, newborn, and maternal death. Many perinatal complications have pathophysiologic mechanisms with a genetic basis. The objective of this chapter is to focus on perinatal genomics and the occurrence of two specific complications: preterm birth and dysfunctional placental phenotype. This chapter includes discussions of genetic variation, mutation and inheritance, gene expression, and genetic biomarkers in relation to preterm birth, in addition to the impact of maternal tobacco smoke exposure on placental phenotype. The concept of epigenetics is also addressed, specifically the regulation of gene expression in the placenta and fetal origins of adult health and disease. There is great potential for nurse-researchers to make valuable contributions to perinatal genomics investigations, but this requires perseverance, increased genetics-based understanding and skills, as well as multidisciplinary mentorship.

Maternal coping style and perceived adequacy of income predict CRH levels at 14-20 weeks of gestation.

OBJECTIVE: This exploratory study examines the role of psychosocial-behavioral variables as predictors of elevated corticotropin-releasing hormone (CRH) at 14-20 weeks of gestation. METHOD: One hundred and twenty women were enrolled into the study. Blood samples were collected at 14-20 weeks of pregnancy and assayed for CRH. Participants completed questionnaires that included the Perceived Stress Scale, the Center for Epidemiologic Studies (CES) Depression Scale, the Pregnancy-Specific Anxiety (PAS) Scale, the Norbeck Social Support Questionnaire, the Life Orientation Test, the Brief COPE scale, and questions regarding violence/abuse, and work, sleep, and nutritional patterns. RESULTS: Pregnant women with high CRH levels (15 pcg/ml and above) perceived their income to be inadequate, slept more hours at night, stood more hours during the day, and used the coping styles of disengagement or religion but not humor. Logistic regression identified three predictors for high CRH (accounting for 42.2% of the variance): perceived inadequacy of income and the use of ''religion'' and ''disengagement'' to cope with stress. CONCLUSIONS: These results are the first known to identify coping style and perceived income inadequacy as predictors of high CRH. Women with perceived inadequacy of income had almost three times the odds for high CRH. Women who used religion or disengagement to cope with stress had 14 times and 7 times the odds for high CRH levels, respectively. Higher CRH levels are associated with preterm birth (PTB). Thus, it may be important to include maternal coping style and perceptions of income inadequacy in future investigations of CRH levels and PTB.

The interaction between chronic stress and pregnancy: preterm birth from a biobehavioral perspective.

Women's health care providers are increasingly aware that chronic stressors--such as poverty, ongoing perceived stress and anxiety, intimate partner violence, and experiences of racism--are associated with an increased incidence of preterm birth in the United States. It is important to increase our understanding of the explanatory pathways involved in these associations. This article discusses the concepts of stress, chronic stress response, allostatic load, the physiology of labor initiation, and the pathophysiologic interactions that may contribute to the occurrence of chronic stress-related preterm birth. Implications for future research and interventions are explored.
