Worries About Labor and Birth: A Population-Based Study of Outcomes for Young Primiparous Women

Predicting labor onset relative to the estimated date of delivery using smart ring physiological data

The transition from pregnancy into parturition is physiologically directed by maternal, fetal and placental tissues. We hypothesize that these processes may be reflected in maternal physiological metrics. We enrolled pregnant participants in the third-trimester (n = 118) to study continuously worn smart ring devices monitoring heart rate, heart rate variability, skin temperature, sleep and physical activity from negative temperature coefficient, 3-D accelerometer and infrared photoplethysmography sensors. Weekly surveys assessed labor symptoms, pain, fatigue and mood. We estimated the association between each metric, gestational age, and the likelihood of a participant's labor beginning prior to (versus after) the clinical estimated delivery date (EDD) of 40.0 weeks with mixed effects regression. A boosted random forest was trained on the physiological metrics to predict pregnancies that naturally passed the EDD versus undergoing onset of labor prior to the EDD. Here we report that many raw sleep, activity, pain, fatigue and labor symptom metrics are correlated with gestational age. As gestational age advances, pregnant individuals have lower resting heart rate 0.357 beats/minute/week, 0.84 higher heart rate variability (milliseconds) and shorter durations of physical activity and sleep. Further, random forest predictions determine pregnancies that would pass the EDD with accuracy of 0.71 (area under the receiver operating curve). Self-reported symptoms of labor correlate with increased gestational age and not with the timing of labor (relative to EDD) or onset of spontaneous labor. The use of maternal smart ring-derived physiological data in the third-trimester may improve prediction of the natural duration of pregnancy relative to the EDD.

Birth, love, and fear: Physiological networks from pregnancy to parenthood

Pregnancy and childbirth are among the most dramatic physiological and emotional transformations of a lifetime. Despite their central importance to human survival, many gaps remain in our understanding of the temporal progression of and mechanisms underlying the transition to new parenthood. The goal of this paper is to outline the physiological and emotional development of the maternal-infant dyad from late pregnancy to the postpartum period, and to provide a framework to investigate this development using non-invasive timeseries. We focus on the interaction among neuroendocrine, emotional, and autonomic outputs in the context of late pregnancy, parturition, and post-partum. We then propose that coupled dynamics in these outputs can be leveraged to map both physiologic and pathologic pregnancy, parturition, and parenthood. This approach could address gaps in our knowledge and enable early detection or prediction of problems, with both personalized depth and broad population scale.

Women's experience of mild to moderate mental health problems during pregnancy, and barriers to receiving support

OBJECTIVE

To explore the experiences of women during pregnancy with mild to moderate mental health problems and describe the barriers to receiving support in relation to their mental health.

RESEARCH DESIGN AND PARTICIPANTS

This paper reports part of a larger project which recruited women and midwives in one hospital in Wales. Participants completed questionnaires in early pregnancy in an antenatal clinic, and the characteristics of women with and without symptoms of anxiety and depression compared. All women were invited to express interest in a follow up interview in late pregnancy. Women identified to have depression and anxiety in early pregnancy, but not under the care of perinatal mental health services, were eligible for interview. Interviews were conducted with 20 women using a visual timeline to aid discussion and were thematically analysed.

FINDINGS

In late pregnancy mental health disorders were reported by nine women, of which five were diagnosed during adulthood. EPDS scores found 15 women had symptoms of mild to moderate depression and GAD-7 scores indicating 15 women with mild to moderate anxiety. Three themes were identified: moods and emotions - past, present and future; expectations and control; knowledge and conversations.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Due to limited access to specialist perinatal mental health services women relied on support networks and self-care to maintain their mental health. More time and better continuity at antenatal appointments along with improved mental health literacy may increase discussions regarding women's mental health during pregnancy. In addition investment is required to develop strategies and improve access to mental health services for women with mild to moderate mental health problems.

Effectiveness of aromatherapy for intrapartum and postpartum emotional problems among parturient women: A meta-analysis of randomized controlled trials

AIM

Perinatal negative emotions are common in parturient women, but the problems are often ignored. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that investigated the effectiveness of aromatherapy for intrapartum anxiety (IPA) and postpartum emotional symptoms (PES).

METHODS

We searched PubMed, Embase, Cochrane library, and ClinicalTrials.gov to identify suitable RCTs for analysis, and the study was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

RESULTS

Nine RCTs were included. The meta-analysis showed aromatherapy reduced IPA during the early to active phase (standardized mean difference [SMD]: -1.56 [-2.55, -0.61]) and during the transition phase (SMD: -3.30 [-4.97, -1.63]) when compared with controls. For the postpartum period, the meta-analyses showed a reduction of postpartum depression (PPD) at week 2 (SMD: -0.43 [-0.82, -0.03]), and a non-significant trend toward the reduction of PPD at weeks 4-6 (SMD: -0.70 [-1.40, 0.01]).

CONCLUSION

Our study found some evidence supporting the effectiveness of aromatherapy in reducing intrapartum anxiety and PES. We recommend the optional use of aromatherapy for intrapartum and postpartum care.

Effects of antepartum education on worries about labor and mode of delivery

AIM

This study evaluated the effects of antenatal education, which was provided in a pregnancy education class, on pregnant women's concerns about labor and the mode of delivery.

MATERIALS AND METHODS

Primigravid pregnant women (n = 144) were enrolled into the study between May 2017 and November 2018. Pregnant women received standard education on nutrition during pregnancy, exercise, methods of coping with pain, and breastfeeding. The participants completed the "Introductory Information Form" and "Oxford Worries about Labour Scale" to collect data.

RESULTS

A statistically significant difference was found between the participants' pain, distress, uncertainty, and interventions in the pre-education, post-education, and postpartum periods and mean total score on the Oxford scale (p<.05). However, education had no significant effect on the mode of delivery (p>.05).

CONCLUSION

Education provided during pregnancy significantly decreased women's worries about labor, but it did not lead to a significant difference in the modes of delivery.

Birthing ball for reducing labor pain: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Multiple factors are thought to affect a woman's sensation of pain during the process of labor. Birthing balls are round exercise balls upon which a woman sits during labor and performs different movements such as rocking back and forth and pelvic rotation. Midwives and nurses have been using birthing balls (also known as Swiss balls) to increase maternal comfort, widen the pelvic outlet, and facilitate progression of labor for women laboring without an epidural. Therefore, the aim of this systematic review and meta-analysis of randomized controlled trials is to assess whether the use of the birthing ball in labor decreases maternal pain during labor.

DATA SOURCES

Research was conducted using PubMed, Scopus, ClinicalTrial.gov, OVID and Cochrane Library as electronic databases. Randomized controlled trials were identified using the following search strategy: "birthing ball" OR "birth ball" OR "swiss ball" OR "exercise ball" AND labor from the inception of each database to June 2019. No restrictions for language or geographic location were applied.

STUDY ELIGIBILITY CRITERIA

Selection criteria included randomized trials of pregnant women with a singleton, cephalic fetus who were randomized to either birthing ball or control group (i.e. no birthing ball) for use in labor.

STUDY APPRAISAL AND SYNTHESIS METHODS

Seven trials with 533 pregnant women were included. 287 (53.8%) were randomized to the intervention group (birthing ball) and 246 (46.2%) were randomized to the control group (no birthing ball). All analyses were done using an intention-to-treat approach, evaluating women according to the treatment group to which they were randomly allocated in the original trials. The primary outcome was labor pain in the first stage of labor. The summary measures were reported as summary relative risk (RR) or as summary mean difference (MD) with 95% of confidence interval (CI) using the random-effects model of DerSimonian and Laird.

RESULTS

Labor pain significantly decreased by 1.70 points in the birthing ball group compared to the control group (MD -1.70 points; 95% CI -2.20 to -1.20). Use of the birthing ball versus no birthing ball did not result in a significant difference in incidence of spontaneous vaginal delivery, operative vaginal delivery, cesarean delivery, or perineal lacerations.

CONCLUSION

The birthing ball is an effective method of pain reduction during labor for women laboring without an epidural.

Birth Observation Among African American Women Prior to Pregnancy

A focused ethnography among African American college students who had observed a live birth prior to their own pregnancy was pursued. Women described two reasons to attend births: curiosity about birth, or a desire to support the birth mother. Women attended the births of friends, family members, or saw their mother give birth to a younger sibling. Themes included pain, operative or traumatic birth, and surprise at the length and/or stages of labor. Some language suggested lingering trauma. Future expectations included painful labor, operative birth or damage, or traumatic labor and birth. Other women felt closer to the infant, or felt more prepared for their own births after observing birth. Prior personal experiences at birth should be explored prenatally.

What are women stressed about after birth?

BACKGROUND

Having a baby is associated with a variety of stressors, change, and adjustment. This study aimed to identify what women find stressful during the early postpartum period in contemporary Western society.

METHODS

Women (n = 148) 6-12 weeks postpartum wrote anonymously about a situation they found stressful as part of the Health after Birth Trial (HABiT) of expressive writing. Transcripts were analyzed for categories of stressors and cross-cutting themes.

RESULTS

Five categories of stressors were identified. Stressors in pregnancy, labor, and the early postpartum period (49.3%) included physical and emotional difficulties, and insensitive treatment by health professionals. Stressors related to adjusting to life with a baby (35.8%) included difficulties coping with a new baby, parenting, juggling responsibilities, changes to physical health, and loneliness. Stressors related to the baby's health (32.4%) included infant digestive problems, acute health problems, long-term impact, and neonatal intensive care unit experiences. Stressors related to breastfeeding (23.7%) included pressure to breastfeed, feeling like a 'bad mum' for not breastfeeding, or wanting to breastfeed and not being able to. Other stressors related to changing relationships (18.2%): with their partner, children, and other family members. Cross-cutting themes that emerged in different stressor categories were women making negative self-appraisals (eg, a bad mum, failure), feeling guilty, and lack of support from others.

DISCUSSION

Our findings emphasize the importance of exploring stressors and psychological well-being with women to provide support, help women's adjustment postpartum, and ensure interventions are offered when appropriate.

Sociodemographic differences in women's experience of early labour care: a mixed methods study

OBJECTIVES

To explore women's experiences of early labour care focusing on sociodemographic differences, and to examine the effect of antenatal education, using mixed methods.

SETTING

England, 2014.

PARTICIPANTS

Women who completed postal questionnaires about their experience of maternity care, including questions about antenatal education, early labour and sociodemographic factors, included space for free-text comments.

OUTCOME MEASURES

Worries about labour, contact with midwives in early labour and subsequent care.

METHODS

This study was based on secondary analysis of a national maternity survey carried out in England in 2014. Quantitative data were analysed using descriptive statistics and binary logistic regression; qualitative data were analysed using a thematic content analytic approach.

RESULTS

Completed questionnaires were received from 4578 women (47% response rate). There were significant differences by sociodemographic factors, particularly ethnicity, in women's worries about early labour. Compared with white women, women from black or minority ethnic groups had an adjusted OR of 1.93 (95% CI 1.56 to 2.39) of feeling worried about not knowing when labour would start. Among women who contacted a midwife at the start of labour, 84% perceived their advice as appropriate, more in older and multiparous women. Overall, 64% of women were asked to come to the hospital at this time, more in multiparous women (adjusted OR 1.63, 95% CI 1.35 to 1.96). Those who did not have access to antenatal education experienced greater worry about early labour. Five themes emerged from the qualitative analysis: 'Differentiating between early and active labour', 'Staff attitudes', 'Not being allowed…', 'Previous labours' and 'Perceived consequences for women'.

CONCLUSION

These findings reinforce the importance of providing reassurance to women in early labour, taking care that women do not feel neglected or dismissed. In particular, primiparous and ethnic minority women reported greater worry about early labour and require additional reassurance.
