Midwives' attitudes towards giving weight-related advice to obese pregnant women

It is estimated that 1 in 5 pregnant women are obese, this poses a significant risk to maternal, fetal and newborn mortality and morbidity and as such, maternal obesity is recognised as a challenge for contemporary and prospective maternity services. As key practitioners in maternity care, midwives are seen as frontline professionals delivering weight-related advice to obese pregnant women. This study aimed to explore midwives' attitudes towards offering obese pregnant women weight-related advice during pregnancy and the puerperium. Nine midwives were interviewed using an in-depth interview schedule. Data were analysed using Colaizzi's (1978) seven-stage thematic approach. Midwives' knowledge of risk associated with maternal obesity was good; advice giving was mainly confined to community practice; the amount and consistency of advice was determined by: women's responses, women's apparent motivation to change and midwives' self-perception as a role model. Four key themes emerged: challenges for practice; perceived proficiency; advice giving skills and midwives' perceived relationship with a woman. Midwives need to address personal issues around body image, as they appear to hinder advice giving, before they can develop effective communication techniques to be able to offer obese pregnant women weight-related advice. The recommendation is to investigate ways in which issues of body image influence midwives ability to offer weight-related advice

Spot protein-creatinine ratio and spot albumin-creatinine ratio in the assessment of pre-eclampsia: a diagnostic accuracy study with decision-analytic model-based economic evaluation and acceptability analysis.

BACKGROUND: The National Institute for Health and Care Excellence (NICE) guidelines highlighted the need for 'large, high-quality prospective studies comparing the various methods of measuring proteinuria in women with new-onset hypertensive disorders during pregnancy'. OBJECTIVES: The primary objective was to evaluate quantitative assessments of spot protein-creatinine ratio (SPCR) and spot albumin-creatinine ratio (SACR) in predicting severe pre-eclampsia (PE) compared with 24-hour urine protein measurement. The secondary objectives were to investigate interlaboratory assay variation, to evaluate SPCR and SACR thresholds in predicting adverse maternal and fetal outcomes and to assess the cost-effectiveness of these models. DESIGN: This was a prospective diagnostic accuracy cohort study, with decision-analytic modelling and a cost-effectiveness analysis. SETTING: The setting was 36 obstetric units in England, UK. PARTICIPANTS: Pregnant women (aged ≥ 16 years), who were at > 20 weeks' gestation with confirmed gestational hypertension and trace or more proteinuria on an automated dipstick urinalysis. INTERVENTIONS: Women provided a spot urine sample for protein analysis (the recruitment sample) and were asked to collect a 24-hour urine sample, which was stored for secondary analysis. A further spot sample of urine was taken immediately before delivery. MAIN OUTCOME MEASURES: Outcome data were collected from hospital records. There were four index tests on a spot sample of urine: (1) SPCR test (conducted at the local laboratory); (2) SPCR test [conducted at the central laboratory using the benzethonium chloride (BZC) assay]; (3) SPCR test [conducted at the central laboratory using the pyrogallol red (PGR) assay]; and (4) SACR test (conducted at the central laboratory using an automated chemistry analyser). The comparator tests on 24-hour urine collection were a central test using the BZC assay and a central test using the PGR assay. The primary reference standard was the NICE definition of severe PE. Secondary reference standards were a clinician diagnosis of severe PE, which is defined as treatment with magnesium sulphate or with severe PE protocol; adverse perinatal outcome; one or more of perinatal or infant mortality, bronchopulmonary dysplasia, necrotising enterocolitis or grade III/IV intraventricular haemorrhage; and economic cost and outcomes. Health service data on service use and costs followed published economic models. RESULTS: In total, 959 women were available for primary analysis and 417 of them had severe PE. The diagnostic accuracy of the four assays on spot urine samples against the reference standards was similar. The three SPCR tests had sensitivities in excess of 90% at prespecified thresholds, with poor specificities and negative likelihood ratios of ≥ 0.1. The SACR test had a significantly higher sensitivity of 99% (confidence interval 98% to 100%) and lower specificity. Receiver operating characteristic (ROC) curves were similar (area under ROC curve between 0.87 and 0.89); the area under the central laboratory's SACR curve was significantly higher (p = 0.004). The central laboratory's SACR test was the most cost-effective option, generating an additional 0.03 quality-adjusted life-years at an additional cost of £45.07 compared with the local laboratory's SPCR test. The probabilistic analysis showed it to have a 100% probability of being cost-effective at the standard willingness-to-pay threshold recommended by NICE. LIMITATIONS: Implementation of NICE guidelines has led to an increased intervention rate in the study population that affected recruitment rates and led to revised sample size calculations. CONCLUSIONS: Evidence from this clinical study does not support the recommendation of 24-hour urine sample collection in hypertensive pregnant women. The SACR test had better diagnostic performance when predicting severe pre-eclampsia. All four tests could potentially be used as rule-out tests for the NICE definition of severe PE. FUTURE WORK: Testing SACR at a threshold of 8 mg/mmol should be studied as a 'rule-out' test of proteinuria. TRIAL REGISTRATION: Current Controlled Trials ISRCTN82607486.

Eating for 1, Healthy and Active for 2; feasibility of delivering novel, compact training for midwives to build knowledge and confidence in giving nutrition, physical activity and weight management advice during pregnancy

Gold OABackground: Women in Wales are more likely to be obese in pregnancy than in any other United Kingdom (UK) country. Midwives are ideally placed to explore nutrition, physical activity and weight management concerns however qualitative studies indicate they lack confidence in raising the sensitive issue of weight. Acknowledging this and the reality of finite time and resources, this study aimed to deliver compact training on nutrition, physical activity and weight management during pregnancy to increase the knowledge and confidence of midwives in this subject. Methods A compact training package for midwives was developed comprising of evidence based nutrition, physical activity and weight management guidance for pregnancy. Training was promoted via midwifery leads and delivered within the Health Board. Questionnaires based on statements from national public health guidance were used to assess changes in self-reported knowledge and confidence pre and post training. Descriptive statistics were applied and 95% confidence intervals were calculated. Results 43 midwives registered for training, 32 (74%) attended and completed the questionnaires. Although, pre training knowledge and confidence varied between participants, statistically significant improvements in self-reported knowledge and confidence were observed post training. 97% indicated knowledge of pregnancy specific food and nutrition messages as ‘better’ (95% CI 85 to 100), as opposed to 3% stating ‘stayed the same’ – 60% stated ‘much better’. 83% indicated confidence to explain the risks of raised BMI in pregnancy was either ‘much’ or ‘somewhat better’ (95% CI 66 to 93), as opposed to 17% stating ‘stayed the same’. 89% indicated confidence to discuss eating habits and physical activity was ‘much’ or ‘somewhat better’ (95% CI 73 to 97) as opposed to 11% stating ‘stayed the same’. Emergent themes highlighted that training was positively received and relevant to midwifery practice. Conclusions This study provides early indications that a compact nutrition, physical activity and weight management training package improves midwives self-reported knowledge and confidence. Cascading training across the midwifery service in the Health Board and conducting further studies to elicit longer term impact on midwifery practice and patient outcomes are recommended

How do women with social risk factors experience United Kingdom maternity care? A realist synthesis

Background Echoing international trends, the most recent United Kingdom reports of infant and maternal mortality found that pregnancies to women with social risk factors are over 50% more likely to end in stillbirth or neonatal death and carry an increased risk of premature birth and maternal death. The aim of this realist synthesis was to uncover the mechanisms that affect women's experiences of maternity care. Methods Using realist methodology, 22 papers exploring how women with a wide range of social risk factors experience maternity care in the United Kingdom were included. The data extraction process identified contexts (C), mechanisms (M), and outcomes (0). Results Three themes, Resources, Relationships, and Candidacy, overarched eight CMO configurations. Access to services, appropriate education, interpreters, practical support, and continuity of care were particularly relevant for women who are unfamiliar with the United Kingdom system and those living chaotic lives. For women with experience of trauma, or those who lack a sense of control, a trusting relationship with a health care professional was key to regaining trust. Many women who have social care involvement during their pregnancy perceive health care services as a system of surveillance rather than support, impacting on their engagement. This, as well as experiences of paternalistic care and discrimination, could be mitigated through the ability to develop trusting relationships. Conclusions The findings provide underlying theory and practical guidance on how to develop safe services that aim to reduce inequalities in women's experiences and birth outcomes

Evaluating the impact of befriending for pregnant asylum seeking and refugee women

NoPregnant asylum-seeking and refugee women are a particularly vulnerable group in society, who may be possibly living alone in poverty in inappropriate accommodation (Dunne, 2007) and experiencing hostile attitudes (Hynes and sale, 2010). They may have poor physical and mental health, placing them at an increased risk of poor pregnancy outcomes (National Institute for Health and Care Excellence (NICE), 2010). Despite this, they are less likely to attend for timely maternity care. This article discusses the evaluation to date of an ongoing befriending project located in Northern england, targeting pregnant asylum-seeking and refugee women and helping to address difficulties that they may face. Volunteer befrienders, who themselves are asylum-seeking and refugee mothers, receive training to provide support and guidance to clients. Preliminary data suggest that befriending has advantages for both client and volunteer: clients appear to develop a trusting relationship with their befriender which facilitates self-confidence and helps overcome social isolation; and the volunteers feel that they are undertaking a worthwhile role and often move onto paid employment. Befriending may be a useful resource for midwives and ultimately improve pregnancy outcomes for asylum-seeking and refugee women

Obesity and normal birth: A qualitative study of clinician’s management of obese pregnant women during labour

Background: Currently one-fifth of women in the UK are obese. Obese, pregnant woman are at an increased risk of experiencing complications of labour and serious morbidity. However, they are also more likely to undergo medical interventions such as induction of labour and caesarean section which in themselves confer additional health risks for obese women such as wound infection and deep vein thrombosis. Reducing unnecessary interventions and increasing normal birth rates for obese women would substantially improve their postnatal health and wellbeing and reduce the burden of NHS resources required to care for them post operatively. This research aimed to explore practitioners’ experiences of and strategies for providing intrapartum care to obese women.  Method: A qualitative methodology was adopted, focus groups and individual interviews were conducted with health professionals. Audio recordings were transcribed verbatim and data analysed using a framework approach.  Results: Twenty-four health professionals participated; Six Consultant Obstetricians two Consultant Anaesthetists and 16 midwives. Three key themes emerged from the data: medicalisation of obese birth; promotion of normal obese birth; and the complexities and contradictions in staff attitudes and behaviours. The overall interpretation is that positive approaches to obese birth offer opportunities to promote normal birth. However, many health professionals find the provision of intrapartum care to obese women challenging, and attitudes and behaviours towards the promotion of normal birth are heterogeneous, complex and contradictory.  Conclusion: The care of obese women during labour is generally medicalised and focussed on the associated risks. However, although there are conflicting views on how to care for obese women, some practitioners do strive to promote normality and optimise the potential for normal birth by challenging current practices and utilise some ‘interventions’ in order to facilitate normality and mobility during childbirth. Obesity is a major and growing health problem and a major cause of morbidity and mortality for pregnant women. It is essential that more positive proactive guidelines are available to maximise normal birth if the postnatal health of obese women is to be improved

Modelling maternal obesity: the effects of a chronic high-fat, high-cholesterol diet on uterine expression of contractile-associated proteins and ex vivo contractile activity during labour in the rat

Maternal obesity is associated with prolonged and dysfunctional labour and emergency caesarean section, but the mechanisms are unknown. The present study investigated the effects of an adiposity-inducing high fat, high-cholesterol (HFHC) diet on uterine contractile associated protein (CAP) expression and ex vivo uterine contractility in term non-labouring (TNL) and term labouring (TL) rats. Female rats were fed either control chow (CON n = 20) or HFHC (n = 20) diet 6 weeks before conception and during pregnancy. On gestational day 21(TNL) or day 22 (TL) CON and HFHC (n = 10) rats were killed to determine plasma cholesterol, triacylglycerol and progesterone concentrations and collection of myometrium for contractility studies and expression of CAPs caveolin-1 (Cav-1), connexin-43 (CX-43) and it’s phosphorylated form (pCX-43), oxytocin receptor (OXTR) and cyclooxygenase-2 (COX-2). HFHC feeding increased visceral fat (P 0.001), plasma cholesterol (P 0.001) and triacylglycerol (P = 0.039) concentrations. Stage of labour effected uterine expression of CAV-1 (P < 0.02), pCX43 and COX-2 (both P < 0.03). CAV-1 and pCX43 decreased but COX-2 increased with parturition. Significant diet- and labour-stage interactions were evident for CX-43 and pCX43 (P < 0.03 and P < 0.004 respectively). CX-43 decreased with TL in HFHC animals but was unaltered in CON. pCX-43 fell with labour in CON but remained high in HFHC. OXTR expression was significantly higher in HFHC compared with CON animals (P < 0.03). Progesterone was higher in HFHC rats at term (P < 0.014) but fell significantly with labour to similar concentrations as CON. Contractility studies identified synchronous contractions of stable amplitude in lean animals, but unstable asynchronous contractions with obesity. Uterine dose response to oxytocin was blunted during labour in HFHC rats with a log EC50 of −8.84 compared with −10.25 M in CON for integral activity (P < 0.05). In conclusion, our adiposity model exhibits adverse effects on contractile activity during labour that can be investigated further to unravel the mechanisms causing uterine dystocia in obese women

Infection and wound breakdown in spontaneous second-degree perineal tears: An exploratory mixed methods study.

BACKGROUND: Perineal trauma affects large numbers of women who have a vaginal birth. This study explores the incidence, etiology and women's experiences of wound infection/breakdown associated with spontaneous second degree tears. METHODS: This was an exploratory mixed methods study set in an urban tertiary National Health Service hospital in 2014-2015. The study included a prospective observational study of second-degree tears using electronic patient records. Infection was defined using criteria adapted from Public Health England's Surgical Site Infection Surveillance Service. We also did a case-control study of maternity records to explore factors associated with perineal infection/wound breakdown, and semi-structured interviews with a purposeful sample of women who experienced wound infection/breakdown. RESULTS: Of 2892 vaginal births during the study period, 76.8% sustained perineal trauma, with second-degree tears most commonly recorded (n = 828/28.6%). Sixteen (1.9%) had a documented infection/wound breakdown which were associated with "compromised wound status" (increased severity of wound/poor suturing; P = 0.033) Women complained of a lack of information about their perineum and poor postnatal surveillance by midwives and physicians. Diagnosis and treatment were often delayed by clinicians' reliance on external signs of wound infection. Although the sample size was small, there were no differences in rates of infection between sutured and unsutured second-degree tears. CONCLUSIONS: Although second-degree tears were common after vaginal birth, wound infection/breakdown was relatively uncommon. Women who report feeling unwell or develop pyrexia postnatally should be assessed urgently. A prospective longitudinal study exploring the long-term sequelae of second-degree tears is needed

Continuity of midwifery care and gestational weight gain in obese women: a randomised controlled trial

Background: The increased prevalence of obesity in pregnant women in Australia and other developed countries is a significant public health concern. Obese women are at increased risk of serious perinatal complications and guidelines recommend weight gain restriction and additional care. There is limited evidence to support the effectiveness of dietary and physical activity lifestyle interventions in preventing adverse perinatal outcomes and new strategies need to be evaluated. The primary aim of this project is to evaluate the effect of continuity of midwifery care on restricting gestational weight gain in obese women to the recommended range. The secondary aims of the study are to assess the impact of continuity of midwifery care on: women&rsquo;s experience of pregnancy care; women&rsquo;s satisfaction with care and a range of psychological factors.Methods/Design: A two arm randomised controlled trial (RCT) will be conducted with primigravid women recruited from maternity services in Victoria, Australia. Participants will be primigravid women, with a BMI&ge;30 who are less than 17 weeks gestation. Women allocated to the intervention arm will be cared for in a midwifery continuity of care model and receive an informational leaflet on managing weight gain in pregnancy. Women allocated to the control group will receive routine care in addition to the same informational leaflet. Weight gain during pregnancy, standards of care, medical and obstetric information will be extracted from medical records. Data collected at recruitment (self administered survey) and at 36 weeks by postal survey will include sociodemographic information and the use of validated scales to measure secondary outcomes.Discussion: Continuity of midwifery care models are well aligned with current Victorian, Australian and many international government policies on maternity care. Increasingly, midwifery continuity models of care are being introduced in low risk maternity care, and information on their application in high risk populations is required. There is an identified need to trial alternative antenatal interventions to reduce perinatal risk factors for women who are obese and the findings from this project may have application in other maternity services. In addition this study will inform a larger trial that will focus on birth and postnatal outcomes.<br /
