Future studies should investigate combinations of tests in multivariable models (rather than single predictors) to improve identification of women at high risk of adverse outcomes in the setting of the hypertensive disorders of pregnancy.
BackgroundObstetrical interventions, including caesarean sections, are increasing in Canada. Canadian women’s psychological states, fatigue, and sleep have not been examined prospectively for contributions to obstetric interventions and adverse neonatal outcomes.Context and purpose of the study: The prospective study was conducted in British Columbia (BC), Canada with 650 low-risk pregnant women. Of those women, 624 were included in this study. Women were recruited through providers’ offices, media, posters, and pregnancy fairs. We examined associations between pregnant women’s fatigue, sleep deprivation, and psychological states (anxiety and childbirth fear) and women’s exposure to obstetrical interventions and adverse neonatal outcomes (preterm, admission to NICU, low APGARS, and low birth weight).MethodsData from our cross-sectional survey were linked, using women’s personal health numbers, to birth outcomes from the Perinatal Services BC database. After stratifying for parity, we used Pearson’s Chi-square to examine associations between psychological states, fatigue, sleep deprivation and maternal characteristics. We used hierarchical logistic regression modeling to test 9 hypotheses comparing women with high and low childbirth fear and anxiety on likelihood of having epidural anaesthetic, a caesarean section (stratified for parity), assisted vaginal delivery, and adverse neonatal outcomes and women with and without sleep deprivation and high levels of fatigue on likelihood of giving birth by caesarean section, while controlling for maternal, obstetrical (e.g., infant macrosomia), and psychological variables.ResultsSignificantly higher proportions of multiparas, reporting difficult and upsetting labours and births, expectations of childbirth interventions, and health stressors, reported high levels of childbirth fear. Women who reported antenatal relationship, housing, financial, and health stressors and multiparas reporting low family incomes were significantly more likely to report high anxiety levels. The hypothesis that high childbirth fear significantly increased the risk of using epidural anaesthesia was supported.ConclusionsControlling for some psychological states and sleep quality while examining other contributors to outcomes decreases the likelihood of linking childbirth fear anxiety, sleep deprivation, and fatigue to increased odds of caesarean section. Ameliorating women’s childbirth fear to reduce their exposure to epidural anaesthesia can occur through developing effective interventions. These include helping multiparous women process previous experiences of difficult and upsetting labour and birth.

Background This review seeks to identify (a) the various components and process outcomes of type 2 diabetes peer support (PS) interventions and (b) the measures implemented to monitor intervention fidelity and evaluate outcomes in these studies. Methods The MEDLINE, PubMed, EMBASE (Excerpta Medica Database), CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PsycINFO databases were searched from inception to May 2019. Two reviewers independently screened and extracted data from eligible articles via the Template for Intervention Description and Replication (TIDieR) checklist (why, what, who provided, how, where, when and how much, tailoring, modifications, and how well). Results Twenty‐three trials were included. The total number of participants was 7178. Most interventions were in primary care. Although face‐to‐face was the most common modality of contact, rates of contact were highest for telephone. Potential peer leaders (PLs) were identified primarily through recommendations from health professionals, based on their communication skills, glycosylated hemoglobin (HbA1c), and coaching interest. PLs were mostly female, university educated, and had a long history of diabetes (≥ 10 years). PL training varied significantly in length and content; the two most frequent topics were communication skills and diabetes knowledge. Although several studies implemented methods to evaluate “intervention fidelity,” only few rigorously assessed the two key components of fidelity, “adherence” and “competence,” through audio‐ and video‐taping or direct observations. Conclusions The impact of PS on participants' health outcomes is well investigated; however, the implementation and evaluation strategies vary significantly across these studies. In the present review, we define the various components of PS interventions and propose suggestions for enhancing the implementation and evaluation of future PS models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
