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.

General and Respiratory Health Outcomes in Adult Survivors of Bronchopulmonary Dysplasia: A Systematic Review

BACKGROUND The purpose of this systematic literature review was to examine current empirical research on general and respiratory health outcomes in adult survivors of bronchopulmonary dysplasia (BPD). METHODS We searched seven databases up to the end of November 2010 (MEDLINE, PubMed, EMBASE, PsycINFO, Maternity and Infant Care, Cumulative Index of Nursing and Allied Health Literature, and Web of Knowledge). We independently screened and included only those studies concerning the assessment of outcome measures in adult survivors of BPD. Data on methodologic design and findings were extracted from each included study; in addition, the methodologic quality of each study was assessed using the Critical Appraisal Skills Programme checklist. RESULTS Fourteen cohort studies met the review criteria. Of those, a total of eight studies were considered to be of high quality (score 9-12), five of moderate quality (score 5-8), and only one was of low quality (score 0-4). In all studies of adult survivors of BPD, differences were found between the index and control groups, suggesting that many adults survivors of BPD who were born preterm or with very low birth weight had more respiratory symptoms and pulmonary function abnormalities compared with their peers. Five studies concerning radiologic findings reported structural changes persisting into adulthood. Findings from three studies suggested impairment in exercise capacity, although firm conclusions were limited by the small sample size in the studies reviewed. CONCLUSIONS Compared with adults born at term, adult survivors of BPD have more impairment in general and respiratory health, which does not seem to diminish over time.

The relationship between breastfeeding and postpartum weight change—a systematic review and critical evaluation

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.

Impaired lung function and Health Status in Adult Survivors of Bronchopulmonary Dysplasia

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 full-term 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. Adult BPD survivors are more likely to have more respiratory symptoms, impaired health status and airflow obstruction than controls http://ow.ly/rF9G9

Pregnancy Planning and Diabetes: A Qualitative Exploration of Women's Attitudes Toward Preconception Care

INTRODUCTION Seeking preconception care is recognized as an important health behavior for women with preexisting diabetes. Yet many women with diabetes do not seek care or advice until after they are pregnant, and many enter pregnancy with suboptimal glycemic control. This study explored the attitudes about pregnancy and preconception care seeking in a group of nonpregnant women with type 1 diabetes mellitus. METHODS In-depth semistructured interviews were completed with 14 nonpregnant women with type 1 diabetes. RESULTS Analysis of the interview data revealed 4 main themes: 1) the emotional complexity of childbearing decisions, 2) preferences for information related to pregnancy, 3) the importance of being known by your health professional, and 4) frustrations with the medical model of care. DISCUSSION 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.

Does intrauterine growth restriction affect quality of life in adulthood

Objective: To compare health-related quality of life in 50-year-old adults who were born at term (⩾37 to 42 weeks’ gestation) with intrauterine growth restriction (IUGR; birth weight <10th centile) and a group born at term without IUGR (⩾10th centile). Design: Case control study. Setting: A large regional maternity hospital in Northern Ireland. Subjects: 235 adults who were born between 1954 and 1956 in the Royal Maternity Hospital, Belfast. 111 subjects born with IUGR and 124 controls with normal birth weight for gestation were compared. Main outcome measure: Health-related quality of life in adulthood was assessed using the Short Form-36 Health Survey (SF-36). Results: The two groups reported similar health-related quality of life on each of the eight dimensions of the SF-36 and there were no significant differences between them. Adjusting for potential confounding variables did not alter this conclusion. Conclusions: The similarity of SF-36 scores indicated that those born with IUGR did not perceive this to adversely influence health-related quality of life at 50 years of age compared with those with normal birth weight.

Executive functioning deficits in young adult survivors of bronchopulmonary dysplasia

Abstract Purpose: To assess long-term impairments of executive functioning in adult survivors of bronchopulmonary dysplasia (BPD). Method: Participants were assessed on measures of executive functioning, health-related quality of life (HRQoL) and social functioning. Survivors of BPD (n = 63; 34 males; mean age 24.2 years) were compared with groups comprising preterm (without BPD) (<1500 g; n = 45) and full-term controls (n = 63). Analysis of variance was used to explore differences among groups for outcome measures. Multiple regression analyzes were performed to identify factors predictive of long-term outcomes. Results: Significantly more BPD adults, compared with preterm and term controls, showed deficits in executive functioning relating to problem solving (OR: 5.1, CI: 1.4–19.3), awareness of behavior (OR: 12.7, CI: 1.5–106.4) and organization of their environment (OR: 13.0, CI: 1.6–107.1). Birth weight, HRQoL and social functioning were predictive of deficits in executive functioning. Conclusions: This study represents the largest sample of survivors into adulthood of BPD and is the first to show that deficits in executive functioning persist. Children with BPD should be assessed to identify cognitive impairments and allow early intervention aimed at ameliorating their effects. Implications for Rehabilitation Adults born preterm with very-low birth weight, and particularly those who develop BPD, are at increased risk of exhibiting defects in executive functioning. Clinicians and educators should be made aware of the impact that BPD can have on the long-term development of executive functions. Children and young adults identified as having BPD should be periodically monitored to identify the need for possible intervention.

Creating an eLearning Resource to Improve Knowledge and Understanding of Pregnancy in the Context of HIV Infection

Patient narratives have much to teach healthcare professionals about the experience of living with a chronic condition. While the biomedical narrative of HIV treatment is hugely encouraging, the narrative of living with HIV continues to be overshadowed by a persuasive perception of stigma. This paper presents how we sought to translate the evidence from a qualitative study of the perspectives of HIV affected pregnant women and expectant fathers on the care they received, from the pre conception to post natal period, into educational material for maternity care practice. Narrative scripts were written based on the original research interviews, with care taken to reflect the key themes from the research. We explore the way in which the qualitative findings bring to life patient and partner experiences and what it means for nurses, midwives and doctors to be prepared to care for couples affected by HIV. In so doing, we challenge the inequity between the dominance of biomedical knowledge over understanding the patient experience in the preparation of health professionals to care for HIV affected women and men who are having a baby or seeking to have a baby.
