Objective To assess the prevalence of overweight and obesity, and the impact of body mass index (BMI) on maternal and neonatal outcomes, in a UK obstetric population. ). Maternal and neonatal outcomes were examined using logistic regression, adjusted for confounding variables.Main outcome measures Maternal and neonatal outcomes.Results Compared with women of normal weight, women who were overweight or obese class I were at significantly increased risk of hypertensive disorders of pregnancy (OR 1.9, 99% CI 1.7-2.3; OR 3.5, 99% CI 2.9-4.2); gestational diabetes mellitus (OR 1.7, 99% CI 1.3-2.3; OR 3.7, 99% CI 2.8-5.0); induction of labour (OR 1.2, 99% CI 1.1-1.3; OR 1.3, 99% CI 1.2-1.5); caesarean section (OR 1.4, 99% CI 1.3-1.5; OR 1.8, 99% CI 1.6-2.0); postpartum haemorrhage (OR 1.4, 99% CI 1.3-1.5; OR 1.8, 1.6-2.0); and macrosomia (OR 1.5, 99% CI 1.3-1.6; OR 1.9, 99% CI 1.6-2.2), with the risks increasing for obese classes II and III. Women in obese class III were at increased risk of preterm delivery (OR 1.6, 99% CI 1.1-2.5), stillbirth (OR 3.0, 99% CI 1.0-9.3), postnatal stay > 5 days (OR 2.1, 99% CI 1.5-3.1), and infant requiring admission to a neonatal unit (OR 1.6, 99% CI 1.0-2.6).Conclusions By categorising women into overweight and obesity subclassifications (classes I -III), this study clearly demonstrates an increasing risk of adverse outcomes across BMI categories, with women who are overweight also at significant risk.

Pregnancy and the postpartum period is a time of increased vulnerability for retention of excess body fat in women. Breastfeeding (BF) has been shown to have many health benefits for both mother and baby; however, its role in postpartum weight management is unclear. Our aim was to systematically review and critically appraise the literature published to date in relation to the impact of BF on postpartum weight change, weight retention and maternal body composition. Electronic literature searches were carried out using MEDLINE, EMBASE, PubMed, Web of Science, BIOSIS, CINAHL and British Nursing Index. The search covered publications up to 12 June 2012 and included observational studies (prospective and retrospective) carried out in BF mothers (either exclusively or as a subgroup), who were ≤ 2 years postpartum and with a body mass index (BMI) >18.5 kg m(-2), with an outcome measure of change in weight (including weight retention) and/or body composition. Thirty-seven prospective studies and eight retrospective studies were identified that met the selection criteria; studies were stratified according to study design and outcome measure. Overall, studies were heterogeneous, particularly in relation to sample size, measurement time points and in the classification of BF and postpartum weight change. The majority of studies reported little or no association between BF and weight change (n=27, 63%) or change in body composition (n=16, 89%), although this seemed to depend on the measurement time points and BF intensity. However, of the five studies that were considered to be of high methodological quality, four studies demonstrated a positive association between BF and weight change. This systematic review highlights the difficulties of examining the association between BF and weight management in observational research. Although the available evidence challenges the widely held belief that BF promotes weight loss, more robust studies are needed to reliably assess the impact of BF on postpartum weight management.

More infants with bronchopulmonary dysplasia (BPD) now survive to adulthood, but little is known regarding persisting respiratory impairment. We report respiratory symptoms, lung function and health-related quality of life (HRQoL) in adult BPD survivors compared with preterm (non-BPD) and fullterm controls.Respiratory symptoms (European Community Respiratory Health Survey) and HRQoL (EuroQol (EQ)-5D) were measured in 72 adult BPD survivors (mean¡SD study age 24.1¡4.0 years; mean¡SD gestational age 27.1¡2.1 weeks; and mean¡SD birth weight 955¡256 g) cared for in the regional neonatal intensive care unit, Royal Maternity Hospital, Belfast, UK (between 1978 and 1993). These were compared with 57 non-BPD controls (mean¡SD study age 25.3¡4.0 years; mean¡SD gestational age 31.0¡2.5 weeks; and mean¡SD birth weight 1238¡222 g) and 78 full-term controls (mean¡SD study age 25.7¡3.8 years; mean¡SD gestational age 39.7¡1.4 weeks; and mean¡SD birth weight 3514¡456 g) cared for at the same hospital. Spirometry was performed on 56 BPD, 40 non-BPD and 55 full-term participants.BPD subjects were twice as likely to report wheeze and three times more likely to use asthma medication than controls. BPD adults had significantly lower forced expiratory volume in 1 s and forced expiratory flow at 25-75% of forced vital capacity than both the preterm non-BPD and full-term controls (all p,0.01). Mean EQ-5D was 6 points lower in BPD adults compared to full-term controls (p,0.05).BPD survivors have significant respiratory and quality of life impairment persisting into adulthood.@ERSpublications Adult BPD survivors are more likely to have more respiratory symptoms, impaired health status and airflow obstruction than controls

These findings raise questions about how preconception care should be provided to women with diabetes and highlight the pivotal importance of supportive, familiar relationships between health professionals and women with diabetes in the provision of individualized care and advice. By improving the quality of relationships and communication between health care providers and patients, we will be better able to provide care and advice that is perceived as relevant to the individual, whatever her stage of family planning.

BackgroundMidwives’ practices during the second stage of labour vary nationally and internationally. We aim to retrieve evidence that supports high-quality intrapartum care by conducting a systematic review of the literature.MethodsElectronic bibliographic databases including PubMed, EMBASE.com, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Maternity and Infant Care Database (through MIDIRS), and The Cochrane Library will be searched to identify studies that meet the inclusion criteria. No language or publication date constraints will be applied. Articles that pass the two-stage screening process will then be assessed for risk of bias and have their reference lists hand searched.DiscussionA midwife’s practice can be influenced by education and cultural practices but ultimately it should be informed by up-to-date research evidence. By analysing and synthesising the results of the studies, this systematic review will provide valuable insight into high-quality evidence-based midwifery care, which can inform practice, education and future research.Systematic review registrationPROSPERO CRD42018088300Electronic supplementary materialThe online version of this article (10.1186/s13643-018-0916-1) contains supplementary material, which is available to authorized users.
