Abstract
BACKGROUND Family support is one of the determinants of lifestyle habits and relevant health behavior for pregnancy outcomes. In India, the joint family system is still practiced. Due to education, urbanization, and industrialization, the family institution continues to play a central role in people's lives. Pregnancy is a crucial period in women's lives. Good care during pregnancy is important for the health of the mother and the newborn baby. During this period, hormonal changes are complex and involve multiple hormones working together to support the developing fetus and prepare the mother's body for labor, delivery, and breastfeeding. To avoid maternal and fetal complications, she needs support from her family throughout pregnancy and the postnatal period. AIM AND OBJECTIVES This study aims to evaluate the influence of the level and quality of family support during pregnancy on maternal and fetal outcomes and to identify any association between the sociodemographic variables and the impact of the level and quality of family support during the first trimester. MATERIAL AND METHODS This study used a quantitative approach with a survey research design. Data were collected from four Primary Health Centers at Karad, Maharashtra, India, i.e., Rethare, Vadgaon, Kale, and Supane. A consecutive sampling technique was used to select the 344 subjects from the Rethare, Vadgaon, Kale, and Supane areas of Karad Taluka. Data were collected before the completion of the first three months of pregnancy, then during the second trimester and after delivery. Upon evaluation, the tool was validated by experts representing a range of specialties, including community health nursing, mental health nursing, obstetric gynecology, and pediatric care. A pilot study was conducted on 30 samples. The data collected were analyzed by using descriptive and inferential statistics. RESULT The findings of the study show a significant association between the psychosocial support received in the first trimester and the total gestational weeks completed at the time of delivery (p < 0.05). The study suggests the need for psychosocial support during the first trimester for better maternal and fetal outcomes. CONCLUSION Psychosocial family support is needed by pregnant women during the first trimester to achieve maternal and fetal outcomes.

Abstract
Perinatal health and health behaviors play a crucial role in maternal and neonatal health. Data examining psychosocial factors which predict self-reported health and health behaviors as well as objective indicators downstream of health behaviors among pregnant women are lacking. In this longitudinal study design with 131 pregnant women, perceived social support was examined as a predictor of self-rated health and average levels of sleep quality, health-promoting and health-impairing behaviors, and red blood cell (RBC) polyunsaturated fatty acids across early, mid, and late pregnancy. Participants provided a blood sample and fatty acid methyl esters were analyzed by gas chromatography. Measures included the Multidimensional Scale of Perceived Social Support, Pittsburgh Sleep Quality Index, and Prenatal Health Behavior Scale. Regression models demonstrated that, after adjustment for income, race/ethnicity, age, relationship status, pre-pregnancy body mass index, greater social support was associated with better self-rated health (p = 0.001), greater sleep quality (p = 0.001), fewer health-impairing behaviors (p = 0.02), and higher RBC omega-3 fatty acids (p = 0.003). Associations among social support with health-promoting behaviors, RBC omega-6 fatty acids, or gestational weight gain were not significant. Findings underscore the benefits of perceived social support in the context of pregnancy. Examination of pathways that link social support with these outcomes will be meaningful in determining the ways in which perinatal psychosocial interventions may promote health.

Abstract
Aim The aim of the present study was to translate the Postpartum Partner Support Scale (PPSS) into Persian and evaluate its psychometric properties among postpartum women. Design A total of 248 women aged 18–39 years participated in this psychometric study. The PPSS was translated into Persian using a forward‐backward method. Confirmatory factor analysis (CFA) and Rasch model analysis were used to assess the psychometric properties of the PPSS. In addition, the Edinburgh Postpartum Depression Scale (EPDS) was completed simultaneously to assess the construct validity. Internal consistency of the questionnaire was assessed by calculating the Cronbach's alpha coefficient and corrected item‐total correlation. Results The unidimensionality of the PPSS was supported in both CFA and Rasch analysis. The PPSS had a significant negative association with EPDS (r = −0.39 p < .001). The scale had excellent internal consistency (Cronbach's alpha = 0.94) and the correlation between items and total score was satisfactory. Conclusion The Persian version of PPSS with 20 items is a valid and reliable scale to assess postpartum support.

Abstract
BACKGROUND Studies consistently show a relationship between social disadvantage and low birthweight. Many countries have programmes offering special assistance to women thought to be at risk for giving birth to a low birthweight infant. These programmes, collectively referred to in this review as additional social support, may include emotional support, which gives a person a feeling of being loved and cared for, tangible/instrumental support, in the form of direct assistance/home visits, and informational support, through the provision of advice, guidance and counselling. The programmes may be delivered by multidisciplinary teams of health professionals, specially trained lay workers, or a combination of lay and professional workers. This is an update of a review first published in 2003 and updated in 2010. OBJECTIVES The primary objective was to assess the effects of programmes offering additional social support (emotional, instrumental/tangible and informational) compared with routine care, for pregnant women believed to be at high risk for giving birth to babies that are either preterm (less than 37 weeks' gestation) or weigh less than 2500 g, or both, at birth. Secondary objectives were to determine whether the effectiveness of support was mediated by timing of onset (early versus later in pregnancy) or type of provider (healthcare professional or lay person). SEARCH METHODS For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) on 5 February 2018, and reference lists of retrieved studies. SELECTION CRITERIA Randomised trials of additional social support during at-risk pregnancy by either a professional (social worker, midwife, or nurse) or specially trained lay person, compared to routine care. We defined additional social support as some form of emotional support (e.g. caring, empathy, trust), tangible/instrumental support (e.g. transportation to clinic appointments, home visits complemented with phone calls, help with household responsibilities) or informational support (advice and counselling about nutrition, rest, stress management, use of alcohol/recreational drugs). DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS This updated review includes a total of 25 studies, with outcome data for 11,246 mothers and babies enrolled in 21 studies. We assessed the overall risk of bias of included studies to be low or unclear, mainly because of limited reporting or uncertainty in how randomisation was generated or concealed (which led us to downgrade the quality of most outcomes to moderate), and the impracticability of blinding participants.When compared with routine care, programmes offering additional social support for at-risk pregnant women may slightly reduce the number of babies born with a birthweight less than 2500 g from 127 per 1000 to 120 per 1000 (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.86 to 1.04; 16 studies, n = 11,770; moderate-quality evidence), and the number of babies born with a gestational age less than 37 weeks at birth from 128 per 1000 to 117 per 1000 (RR 0.92, 95% CI 0.84 to 1.01, 14 studies, n = 12,282; moderate-quality evidence), though the confidence intervals for the pooled effect for both of these outcomes just crossed the line of no effect, suggesting any effect is not large. There may be little or no difference between interventions for stillbirth/neonatal death (RR 1.11, 95% CI 0.88 to 1.41; 15 studies, n = 12,091; low-quality evidence). Secondary outcomes of moderate quality suggested that there is probably a reduction in caesarean section (from 215 per 1000 to 194 per 1000; RR 0.90, 95% CI 0.83 to 0.97; 15 studies, n = 9550), a reduction in the number of antenatal hospital admissions per participant (RR 0.78, 95% CI 0.68 to 0.91; 4 studies; n = 787), and a reduction in the mean number of hospitalisation episodes (mean difference -0.05, 95% CI -0.06 to -0.04; 1 study, n = 1525) in the social support group, compared to the controls.Postnatal depression and women's satisfaction were reported in different ways in the studies that considered these outcomes and so we could not include data in a meta-analysis. In one study postnatal depression appeared to be slightly lower in the support group in women who screened positively on the Edinbugh Postnatal Depression Scale at eight to 12 weeks postnatally (RR 0.74, 95% CI 0.55 to 1.01; 1 study, n = 1008; moderate-quality evidence). In another study, again postnatal depression appeared to be slightly lower in the support group and this was a self-report measure assessed at six weeks postnatally (RR 0.85, 95% CI 0.69 to 1.05; 1 study, n = 458; low-quality evidence). A higher proportion of women in one study reported that their prenatal care was very helpful in the supported group (RR 1.17, 95% CI 1.05 to 1.30; 1 study, n = 223; moderate-quality evidence), although in another study results were similar. Another study assessed satisfaction with prenatal care as being "not good" in 51 of 945 in the additional support group, compared with 45 of 942 in the usual care group.No studies considered long-term morbidity for the infant. No single outcome was reported in all studies. Subgroup analysis demonstrated consistency of effect when the support was provided by a healthcare professional or a trained lay worker.The descriptions of the additional social support were generally consistent across all studies and included emotional support, tangible support such as home visits, and informational support. AUTHORS' CONCLUSIONS Pregnant women need the support of caring family members, friends, and health professionals. While programmes that offer additional social support during pregnancy are unlikely to have a large impact on the proportion of low birthweight babies or birth before 37 weeks' gestation and no impact on stillbirth or neonatal death, they may be helpful in reducing the likelihood of caesarean birth and antenatal hospital admission.

Understanding periviable birth: A microeconomic alternative to the dysregulation narrative. Soc Sci Med 2017; 233:281-284.

Abstract
Periviable infants (i.e., those born in the 20th through 26th weeks of gestation) suffer much morbidity and approximately half die in the first year of life. Attempts to explain and predict these births disproportionately invoke a "dysregulation" narrative. Research inspired by this narrative has not led to efficacious interventions. The clinical community has, therefore, urged novel approaches to the problem. We aim to provoke debate by offering the theory, inferred from microeconomics, that risk tolerant women carry, without cognitive involvement, high risk fetuses farther into pregnancy than do other women. These extended high-risk pregnancies historically ended in stillbirth but modern obstetric practices now convert a fraction to periviable births. We argue that this theory deserves testing because it suggests inexpensive and noninvasive screening for pregnancies that might benefit from the costly and invasive interventions clinical research will likely devise.

Preference for cesarean section in young nulligravid women in eight OECD countries and implications for reproductive health education. Reprod Health 2017; 14:116.

Abstract
Background Efforts to reduce unnecessary Cesarean sections (CS) in high and middle income countries have focused on changing hospital cultures and policies, care provider attitudes and behaviors, and increasing women’s knowledge about the benefits of vaginal birth. These strategies have been largely ineffective. Despite evidence that women have well-developed preferences for mode of delivery prior to conceiving their first child, few studies and no interventions have targeted the next generation of maternity care consumers. The objectives of the study were to identify how many women prefer Cesarean section in a hypothetical healthy pregnancy, why they prefer CS and whether women report knowledge gaps about pregnancy and childbirth that can inform educational interventions. Methods Data was collected via an online survey at colleges and universities in 8 OECD countries (Australia, Canada, Chile, England, Germany, Iceland, New Zealand, United States) in 2014/2015. Childless young men and women between 18 and 40 years of age who planned to have at least one child in the future were eligible to participate. The current analysis is focused on the attitudes of women (n = 3616); rates of CS preference across countries are compared, using a standardized cohort of women aged 18–25 years, who were born in the survey country and did not study health sciences (n = 1390). Results One in ten young women in our study preferred CS, ranging from 7.6% in Iceland to 18.4% in Australia. Fear of uncontrollable labor pain and fear of physical damage were primary reasons for preferring a CS. Both fear of childbirth and preferences for CS declined as the level of confidence in women’s knowledge of pregnancy and birth increased. Conclusion Education sessions delivered online, through social media, and face-to-face using drama and stories told by peers (young women who have recently had babies) or celebrities could be designed to maximize young women’s capacity to understand the physiology of labor and birth, and the range of methods available to support them in coping with labor pain and to minimize invasive procedures, therefore reducing fear of pain, bodily damage, and loss of control. The most efficacious designs and content for such education for young women and girls remains to be tested in future studies.

Abstract
Objectives African Americans are two times more likely to suffer adverse birth outcomes (i.e., low birth weight, preterm birth, and infant mortality) when compared to all other ethnic groups and this pattern is no different for Douglas County, Nebraska, where the majority of African Americans in Nebraska reside. Our goal was to identify factors, as described by local women, that contribute to adverse birth outcomes in the predominantly African American community of Northeast Douglas County in Omaha, NE, to ensure that these women's voices were included in the development of interventions to improve their neighborhood's birth outcomes. The paper describes the results of a qualitative needs assessment of these women which will aid in the design and implementation of neighborhood-based solutions. Methods We brought together a group of women with varying levels of birthing experience, time spent living in the neighborhood, and overall community involvement. Individual in-depth, in person, and telephone interviews were used to collect participants' perceptions of birth outcomes, neighborhood resources for pregnant women, and neighborhood strengths and weaknesses. Results The needs assessment identified that, although women in this neighborhood have experience with adverse birth outcomes, these experiences are not discussed resulting in a lack of awareness of the wide spread racial disparities in birth outcomes and the efforts and resources to address this public health problem. Conclusions for Practice This study reveals the power of direct conversations with women impacted by adverse birth outcomes, as they must be primary partners in any efforts to improve birth outcomes.

Abstract
Preterm infants are born prior to completion of 37 weeks of gestation. These patients are seen on the rise despite the efforts put in to control them. Global incidence of preterm birth is around 9.6% of all birth representing 12.9 million births with regional disparities: From 12% to 13% in USA, from 5% to 9% in Europe, and 18% in Africa. First reported by Offenbacher et al. in 1996 relationship exist between maternal periodontal disease and delivery of a preterm infant. This article reviews the recent epidemiological and biological data. The articles were searched on Google, PubMed recent articles were selected. Mainly, three hypotheses by which periodontal bacteria can affect the outcome of pregnancy. Biological hypothesis: (a) Bacterial spreading, (b) Inflammatory products dissemination, (c) Role of fetomaternal immune response against oral pathogens. The promotion of the early detection and treatments of periodontal disease in young women before and during pregnancy will be beneficial especially for women at risk.

Abstract
BACKGROUND To reduce the morbidity and mortality associated with preterm birth, home uterine activity monitoring aims for early detection of increased contraction frequency, and early intervention with tocolytic drugs to inhibit labour and prolong pregnancy. However, the effectiveness of such monitoring is disputed. OBJECTIVES To determine whether home uterine activity monitoring is effective in improving the outcomes for women and their infants considered to be at high risk of preterm birth, when compared with conventional or other care packages that do not include home uterine monitoring. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2014), CENTRAL (The Cochrane Library 2014, Issue 8), MEDLINE (1966 to 31 August 2014), EMBASE (1974 to 31 August 2014), CINAHL (1982 to 31 August 2014) and scanned reference lists of retrieved studies. SELECTION CRITERIA Randomised control trials of home uterine activity monitoring, with or without patient education programmes, for women at risk for preterm birth, in comparison to the same care package without home uterine activity monitoring. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We did not attempt to contact authors to resolve queries. MAIN RESULTS There were 15 included studies (total number of enrolled participants 6008); 13 studies contributed data. Women using home uterine monitoring were less likely to experience preterm birth at less than 34 weeks (risk ratio (RR) 0.78; 95% confidence interval (CI) 0.62 to 0.99; three studies, n = 1596; fixed-effect analysis) (GRADE high). The significant difference was not evident when we carried out a sensitivity analysis, restricting the analysis to studies at low risk of bias based on study quality (RR 0.75; 95% CI 0.57 to 1.00, one study, 1292 women). There was no significant difference in the rate of perinatal mortality (RR 1.22; 95% CI 0.86 to 1.72; two studies, n = 2589) (GRADE low)There was no significant difference in the number of preterm births at less than 37 weeks (average RR 0.85; CI 0.72 to 1.01; eight studies, n = 4834; random-effects, T² = 0.03, I² = 68%) (GRADE very low). Infants born to women using home uterine monitoring were less likely to be admitted to neonatal intensive care unit (average RR 0.77; 95% CI 0.62 to 0.96; five studies, n = 2367; random-effects, T² = 0.02, I² = 32%) (GRADE moderate). The difference was not statistically significant when only high quality studies were included (RR 0.86; 95% CI 0.74 to 1.01; one study, n = 1292). Women using home uterine monitoring made more unscheduled antenatal visits (mean difference (MD) 0.49; 95% CI 0.39 to 0.62; two studies, n = 3707) (GRADE moderate). Women using home uterine monitoring were also more likely to have prophylactic tocolytic drug therapy (average RR 1.21; 95% CI 1.01 to 1.45; seven studies, n = 4316; random-effects. T² = 0.03, I² = 62%) but this difference was no longer significant when the analysis was restricted to higher quality studies (average RR 1.22; 95% CI 0.90 to 1.65, three studies, n = 3749,random-effects, T² = 0.05, I² = 76%) (GRADE low). One small study reported that the home uterine monitoring group spent fewer days in hospital antenatally. No data on maternal anxiety or acceptability were found. AUTHORS' CONCLUSIONS Home uterine monitoring may result in fewer admissions to a neonatal intensive care unit but more unscheduled antenatal visits and tocolytic treatment, but the level of evidence is generally low to moderate. Important group differences were not evident when sensitivity analysis was undertaken using only high quality trials. There is no impact on maternal and perinatal outcomes such as perinatal mortality or incidence of preterm birth.

Abstract
OBJECTIVE To evaluate a possible association between neighbourhood socio-economic status and spontaneous premature birth in Alberta births. METHODS The study design was a retrospective cohort of all births in Alberta for the years 2001 and 2006. The primary outcome was spontaneous preterm birth at <37 weeks gestation. Neighbourhood socio-economic status was measured by the Pampalon Material Deprivation Index for each Statistics Canada census dissemination area. Births were linked to dissemination area using maternal postal codes. RESULTS The analysis comprised 73,585 births, in which the rate of spontaneous preterm delivery at <37 weeks was 5.3%. The rates of spontaneous preterm delivery for each neighbourhood socio-economic category ranged from 4.9% (95% CI 4.5%-5.2%) in the highest category to 6.3% (95% CI 6.0%-6.7%) in the lowest (p<0.001). After controlling for smoking, parity, maternal age and year, we found that women living in the highest socio-economic status neighbourhoods had an adjusted spontaneous preterm birth rate of 5.1% (95% CI 4.7%-5.5%) compared to 6.0% (95% CI 5.6%-6.4%) for women living in the lowest (p=0.003). CONCLUSION This study documented a modest increase in the risk of spontaneous preterm birth with low socio-economic status. The possibility of confounding bias cannot be ruled out.

Abstract
To assess whether a measure of prenatal case management (PCM) dosage is more sensitive than a dichotomous PCM exposure measure when evaluating the effect of PCM on low birthweight (LBW) and preterm birth (PTB). We constructed a retrospective cohort study (N = 16,657) of Iowa Medicaid-insured women who had a singleton live birth from October 2005 to December 2006; 28 % of women received PCM. A PCM dosage measure was created to capture duration of enrollment, total time with a case manager, and intervention breadth. Propensity score (PS)-adjusted odds ratios (ORs), and 95 % confidence intervals (95 % CIs) were calculated to assess the risk of each outcome by PCM dosage and the dichotomous PCM exposure measure. PS-adjusted ORs of PTB were 0.88 (95 % CI 0.70-1.11), 0.58 (95 % CI 0.47-0.72), and 1.43 (95 % CI 1.23-1.67) for high, medium, and low PCM dosage, respectively. For LBW, the PS-adjusted ORs were 0.76 (95 % CI 0.57-1.00), 0.64 (95 % CI 0.50-0.82), and 1.36 (95 % CI 1.14-1.63), for high, medium, and low PCM dosage, respectively. The PCM dichotomous participation measure was not significantly associated with LBW (OR = 0.95, 95 % CI 0.82-1.09) or PTB (0.97, 95 % CI 0.87-1.10). The reference group in each analysis is No PCM. PCM was associated with a reduced risk of adverse pregnancy outcomes for Medicaid-insured women in Iowa. PCM dosage appeared to be a more sensitive measure than the dichotomous measure of PCM participation.

Abstract
BACKGROUND AND OBJECTIVE Home visiting programs seek to improve care management for women at high risk for preterm birth (<37 weeks). Our objective was to evaluate the effect of home visiting dosage on preterm birth and small for gestational age (SGA) infants. METHODS Retrospective cohort study of women in southwest Ohio with a singleton pregnancy enrolled in home visiting before 26 weeks' gestation. Vital statistics and hospital discharge data were linked with home visiting data from 2007 to 2010 to ascertain birth outcomes. Eligibility for home visiting required ≥1 of 4 risk factors: unmarried, low income, <18 years of age, or suboptimal prenatal care. Logistic regression tested the association of gestational age at enrollment and number of home visits before 26 weeks with preterm birth. Proportional hazards analysis tested the association of total number of home visits with SGA status. RESULTS Among 441 participants enrolled by 26 weeks, 10.9% delivered preterm; 17.9% of infants were born SGA. Mean gestational age at enrollment was 18.9 weeks; mean number of prenatal home visits was 8.2. In multivariable regression, ≥8 completed visits by 26 weeks compared with ≤3 visits was associated with an odds ratio 0.38 for preterm birth (95% confidence interval: 0.16-0.87), while having ≥12 total home visits compared with ≤3 visits was significantly associated with a hazards ratio 0.32 for SGA (95% confidence interval: 0.15-0.68). CONCLUSIONS Among at-risk, first time mothers enrolled prenatally in home visiting, higher dosage of intervention is associated with reduced likelihood of adverse pregnancy outcomes.

Abstract
AIMS Psychosocial stress during pregnancy (PSP) is a risk factor of growing interest in the etiology of preterm birth (PTB). This literature review assesses the published evidence concerning the association between PSP and PTB, highlighting established and hypothesized physiological pathways mediating this association. METHOD The PubMed and Web of Science databases were searched using the keywords "psychosocial stress", "pregnancy", "pregnancy stress", "preterm", "preterm birth", "gestational age", "anxiety", and "social support". After applying the exclusion criteria, the search produced 107 articles. RESULTS The association of PSP with PTB varied according to the dimensions and timing of PSP. Stronger associations were generally found in early pregnancy, and most studies demonstrating positive results found moderate effect sizes, with risk ratios between 1.2 and 2.1. Subjective perception of stress and pregnancy-related anxiety appeared to be the stress measures most closely associated with PTB. Potential physiological pathways identified included behavioral, infectious, neuroinflammatory, and neuroendocrine mechanisms. CONCLUSIONS Future research should examine the biological pathways of these different psychosocial stress dimensions and at multiple time points across pregnancy. Culture-independent characterization of the vaginal microbiome and noninvasive monitoring of cholinergic activity represent two exciting frontiers in this research.

Abstract
OBJECTIVES Health psychology has contributed significantly to understanding the link between psychological factors and health and well-being, but it has not often incorporated advances in relationship science into hypothesis generation and study design. We present one example of a theoretical model, following from a major relationship theory (attachment theory) that integrates relationship constructs and processes with biopsychosocial processes and health outcomes. METHOD We briefly describe attachment theory and present a general framework linking it to dyadic relationship processes (relationship behaviors, mediators, and outcomes) and health processes (physiology, affective states, health behavior, and health outcomes). We discuss the utility of the model for research in several health domains (e.g., self-regulation of health behavior, pain, chronic disease) and its implications for interventions and future research. RESULTS This framework revealed important gaps in knowledge about relationships and health. Future work in this area will benefit from taking into account individual differences in attachment, adopting a more explicit dyadic approach, examining more integrated models that test for mediating processes, and incorporating a broader range of relationship constructs that have implications for health. CONCLUSIONS A theoretical framework for studying health that is based in relationship science can accelerate progress by generating new research directions designed to pinpoint the mechanisms through which close relationships promote or undermine health. Furthermore, this knowledge can be applied to develop more effective interventions to help individuals and their relationship partners with health-related challenges.

Abstract
OBJECTIVES To determine if (1) birth outcomes among women on Medicaid differ significantly from outcomes of those with private insurance, after controlling for known risk factors, and (2) enhanced prenatal care influences care use and birth outcomes. METHODS This is a review of studies published between 1989 and 2009 that examined birth outcomes (1) between women on Medicaid and those with private insurance and (2) among Medicaid enrollees who received comprehensive prenatal care. RESULTS When corrected for risk variables, birth outcomes are not different between private insurance and Medicaid patients. The impact of comprehensive prenatal care programs on birth outcomes varies across states and regions. CONCLUSIONS There is a need for critical evaluation of comprehensive programs in a regional and state context to determine opportunities for improvement.

Abstract
The aim of this study was to describe expectant mothers' and fathers' perceived needs of support during pregnancy. Twenty-two women and 10 men were interviewed in four focus groups and 13 individual interviews. Systematic text condensation was performed to analyze the data. Parents described not only a broad spectrum of social support needs but also needs of psychological and physical support. They also requested to share their experiences with others. The foci of care and parents' needs of support are more harmonized with medical support than with psychological and emotional support. Mothers' needs were predominately addressed in the health services, but fathers often felt "invisible." Antenatal services may need to offer more customized individual support and emphasize peer support in groups; the challenge is to involve both parents through communication and encouragement so they can support each other.

Abstract
BACKGROUND Maternity care providers, particularly midwives, have a window of opportunity to influence pregnant women about positive health choices. This aim of this paper is to identify evidence of effective public health interventions from good quality systematic reviews that could be conducted by midwives. METHODS Relevant databases including MEDLINE, Pubmed, EBSCO, CRD, MIDIRS, Web of Science, The Cochrane Library and Econlit were searched to identify systematic reviews in October 2010. Quality assessment of all reviews was conducted. RESULTS Thirty-six good quality systematic reviews were identified which reported on effective interventions. The reviews were conducted on a diverse range of interventions across the reproductive continuum and were categorised under: screening; supplementation; support; education; mental health; birthing environment; clinical care in labour and breast feeding. The scope and strength of the review findings are discussed in relation to current practice. A logic model was developed to provide an overarching framework of midwifery public health roles to inform research policy and practice. CONCLUSIONS This review provides a broad scope of high quality systematic review evidence and definitively highlights the challenge of knowledge transfer from research into practice. The review also identified gaps in knowledge around the impact of core midwifery practice on public health outcomes and the value of this contribution. This review provides evidence for researchers and funders as to the gaps in current knowledge and should be used to inform the strategic direction of the role of midwifery in public health in policy and practice.

Abstract
Prenatal depression has been linked to adverse reproductive outcomes including preterm labor and delivery, and low birth weight. Social support also has been linked to birth outcomes, and may buffer infants from the adverse impact of maternal depression. In this prospective study, 235 pregnant women completed questionnaires about depression and social support. Clinical interviews were administered to assess for DSM-IV axis I disorders. Following delivery, birth outcomes were obtained from medical records. Babies of depressed mothers weighed less, were born earlier and had lower Apgar scores than babies of nondepressed mothers. Depressed women had smaller social support networks and were less satisfied with support from social networks. We found no direct associations between perceived social support and birth weight. However, depressed women who rated their partners as less supportive had babies who were born earlier and had lower Apgar scores than depressed mothers with higher perceived partner support. Women's perception of partner support appears to buffer infants of depressed mothers from potential adverse outcomes. These results are notable in light of the low-risk nature of our sample and point to the need for continued depression screening in pregnant women and a broader view of risk for adverse birth outcomes. The results also suggest a possible means of intervention that may ultimately lead to reductions in adverse birth outcomes.

Abstract
BACKGROUND To reduce the morbidity and mortality associated with preterm birth, home uterine activity monitoring aims for early detection of increased contraction frequency, and early intervention with tocolytic drugs to inhibit labour and prolong pregnancy. However, the effectiveness of such monitoring is disputed. OBJECTIVES To determine whether home uterine activity monitoring is effective in improving the outcomes for women and their infants considered to be at high risk of preterm birth, when compared with conventional or other care packages that do not include home uterine monitoring. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2011), CENTRAL (The Cochrane Library 2011, Issue 4 of 4), MEDLINE (1966 to 30 November 2011), EMBASE (1974 to 30 November 2011), CINAHL (1982 to 30 November 2011) and scanned reference lists of retrieved studies. SELECTION CRITERIA Randomised control trials of home uterine activity monitoring, with or without patient education programmes, for women at risk for preterm birth, in comparison to the same care package without home uterine activity monitoring. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, extracted data and assessed risk of bias. Data were checked for accuracy. We did not attempt to contact authors to resolve queries. MAIN RESULTS There were 15 included studies (total number of enrolled participants 6008); 13 studies contributed data. Women using home uterine monitoring were less likely to experience preterm birth at less than 34 weeks (risk ratio (RR) 0.78; 95% confidence interval (CI) 0.62 to 0.99; three studies, n = 1596; fixed-effect analysis). However, this significant difference was not evident when we carried out a sensitivity analysis, restricting the analysis to studies at low risk of bias based on study quality (RR 0.75; 95% CI 0.57 to 1.00, one study, 1292 women). There was no significant difference in the rate of perinatal mortality (RR 1.22; 95% CI 0.86 to 1.72; two studies, n = 2589).There was no significant difference in the number of preterm births at less than 37 weeks (average RR 0.85; CI 0.72 to 1.01; eight studies, n = 4834; random effects, T(2) = 0.03, I(2) = 68%). Infants born to women using home uterine monitoring were less likely to be admitted to neonatal intensive care unit (average RR 0.77; 95% CI 0.62 to 0.96; five studies, n = 2367; random-effects, T(2) = 0.02, I(2) = 32%). Although this difference was not statistically significant when only high quality studies were included (RR 0.86; 95% CI 0.74 to 1.01; one study, n = 1292). Women using home uterine monitoring made more unscheduled antenatal visits (mean difference (MD) 0.49; 95% CI 0.39 to 0.62; two studies, n = 2807). Women using home uterine monitoring were also more likely to have prophylactic tocolytic drug therapy (average RR 1.21; 95% CI 1.01 to 1.45; seven studies, n = 4316; random-effects. T(2) = 0.03, I(2) = 62%) but this difference was no longer significant when the analysis was restricted to high quality studies (average RR 1.22; 95% CI 0.90 to 1.65, three studies, n = 3749,random effects, T(2) = 0.05, I(2) = 76%). One small study reported that the home uterine monitoring group spent fewer days in hospital antenatally. No data on maternal anxiety or acceptability were found. AUTHORS' CONCLUSIONS Home uterine monitoring may result in fewer admissions to a neonatal intensive care unit but more unscheduled antenatal visits and tocolytic treatment. There is no impact on maternal and perinatal outcomes such as perinatal mortality or incidence of preterm birth.

Abstract
Background Threatened miscarriage involves vaginal bleeding in a pregnancy that remains viable. This is a common early pregnancy complication with increased risk factors for early pregnancy loss, preterm premature rupture of membranes (PPROM), preterm delivery, low birth weight babies and maternal antepartum haemorrhage. Currently there are no recommended medical treatment options, rather women receive advice that centres on a 'wait and see' approach. For women with a history of unexplained recurrent miscarriage providing supportive care in a subsequent pregnancy improves live birthing outcomes, but the provision of supportive care to women experiencing threatened miscarriage has to date not been examined. Discussion While it is known that 50-70% of miscarriages occur due to chromosomal abnormalities, the potential for therapeutic intervention amongst the remaining percentage of women remains unknown. Complementary and alternative medicine (CAM) therapies have the potential to provide supportive care for women presenting with threatened miscarriage. Within fertility research, acupuncture demonstrates beneficial hormonal responses with decreased miscarriage rates, raising the possibility acupuncture may promote specific beneficial effects in early pregnancy. With the lack of current medical options for women presenting with threatened miscarriage it is timely to examine the possible treatment benefits of providing CAM therapies such as acupuncture. Summary Despite vaginal bleeding being a common complication of early pregnancy there is often reluctance from practitioners to discuss with women and medical personal how and why CAM may be beneficial. In this debate article, the physiological processes of early pregnancy together with the concept of providing supportive care and acupuncture are examined. The aim is to raise awareness and promote discussion as to the beneficial role CAM may have for women presenting with threatened miscarriage.

Abstract
BACKGROUND Maternal, neonatal and child health outcomes are worse in families from black and ethnic minority groups and disadvantaged backgrounds. There is little evidence on whether lay support improves maternal and infant outcomes among women with complex social needs within a disadvantaged multi-ethnic population in the United Kingdom (UK). METHOD/DESIGN The aim of this study is to evaluate a lay Pregnancy Outreach Worker (POW) service for nulliparous women identified as having social risk within a maternity service that is systematically assessing social risks alongside the usual obstetric and medical risks. The study design is a randomised controlled trial (RCT) in nulliparous women assessed as having social risk comparing standard maternity care with the addition of referral to the POW support service. The POWs work alongside community midwifery teams and offer individualised support to women to encourage engagement with services (health and social care) from randomisation (before 28 weeks gestation) until 6 weeks after birth. The primary outcomes have been chosen on the basis that they are linked to maternal and infant health. The two primary outcomes are engagement with antenatal care, assessed by the number of antenatal visits; and maternal depression, assessed using the Edinburgh Postnatal Depression Scale at 8-12 weeks after birth. Secondary outcomes include maternal and neonatal morbidity and mortality, routine child health assessments, including immunisation uptake and breastfeeding at 6 weeks. Other psychological outcomes (self efficacy) and mother-to-infant bonding will also be collected using validated tools.A sample size of 1316 will provide 90% power (at the 5% significance level) to detect increased engagement with antenatal services of 1.5 visits and a reduction of 1.5 in the average EPDS score for women with two or more social risk factors, with power in excess of this for women with any social risk factor. Analysis will be by intention to treat. Qualitative research will explore the POWs' daily work in context. This will complement the findings of the RCT through a triangulation of quantitative and qualitative data on the process of the intervention, and identify other contextual factors that affect the implementation of the intervention. DISCUSSION The trial will provide high quality evidence as to whether or not lay support (POW) offered to women identified with social risk factors improves engagement with maternity services and reduces numbers of women with depression.

Abstract
We describe adverse pregnancy outcomes, including congenital anomalies, fetal, neonatal, and infant mortality among a Missouri population of low-income, rural mothers who participated in two randomized smoking cessation trials. In the Baby BEEP (BB) trial, 695 rural women were recruited from 21 WIC clinics with 650 women's pregnancy outcomes known (93.5% retention rate). Following the BB trial, 298 women who had a live infant after November 2004 were recruited again into and completed the Baby Beep for Kids (BBK) trial. Simple statistics describing the population and perinatal and postneonatal mortality rates were calculated. Of the adverse pregnancy outcomes (n = 79), 29% were spontaneous abortions of less than 20 weeks' gestation, 23% were premature births, and 49% were identified birth defects. The perinatal mortality rate was 15.9 per 1000 births (BB study) compared with 8.6 per 1000 births (state of Missouri) and 8.5 per 1000 births (United States). The postneonatal infant mortality rate was 13.4 per 1000 live births (BBK) compared with 2.1 per 1000 live births (United States). The health disparity in this population of impoverished, rural, pregnant women who smoke, particularly in regard to perinatal and infant deaths, warrants attention.

Abstract
BACKGROUND Cervical dilatation is commonly documented on a partogram indicating the expected rate of progress of labor. Although deviations from such a line can be used to indicate abnormal progress, what constitutes the "normal" rate of cervical dilation is still largely unknown. The objectives of this study were to assess the variability of the rate of cervical dilation in nulliparous women and to determine whether the rate of labor was independent of dilation on admission. METHODS We analyzed a cohort of consecutive nulliparous women with spontaneous labor at term and singleton fetuses in cephalic presentation. Exclusion criteria were gestational age less than 37 weeks, induction of labor, or the presence of a uterine scar. Management of labor was standardized using set protocols of care. Active labor was diagnosed as regular contractions every 10 minutes or less, lasting more than 40 seconds, with cervical effacement more than 80 percent and dilation of 2 cm. Vaginal examinations were performed by a dedicated midwife every 2 hours. Amniotomy was performed for slow progress or arrest of dilation over 2 hours. Oxytocin was administered for arrest of cervical dilation for 2 hours with membranes ruptured. Data pertaining to cases ending in cesarean delivery were included up to the time of cesarean section. RESULTS The study sample comprised 1,119 women at 39.7 ± 1.1 weeks with an average duration of labor of 4.1 ± 2.4 hours. The rate of oxytocin use was 27 percent and of epidural analgesia 5 percent. The rate of oxytocin use was inversely related to cervical dilation on admission. Cesarean delivery was performed in 6 percent of women. Duration of labor at each centimeter of cervical dilation on admission showed a broad distribution (e.g., at 4 cm: median = 5.5, range: 0.8-12.5 hr). The rate of labor progression (expressed as the slope of the dilation-vs-time curve) was approximately 1.5 cm/hr, and it was essentially independent of cervical dilation on admission (r = 0.034, p = 0.267). A deceleration phase seemed to be present toward the end of the active phase of labor (approximately 9 cm). CONCLUSION In our setting, the rate of labor in nulliparous women at term was highly variable, and it did not appear to be affected by cervical dilation on admission.

Abstract
Logistic regression and spatial analytic techniques are used to model fetal distress risk as a function of maternal exposure to Hurricane Andrew. First, monthly time series compare the proportion of infants born distressed in hurricane affected and unaffected areas. Second, resident births are analyzed in Miami-Dade and Broward counties, before, during, and after Hurricane Andrew. Third, resident births are analyzed in all Florida locales with 100,000 or more persons, comparing exposed and unexposed gravid females. Fourth, resident births are analyzed along Hurricane Andrew's path from southern Florida to northeast Mississippi. Results show that fetal distress risk increases significantly with maternal exposure to Hurricane Andrew in second and third trimesters, adjusting for known risk factors. Distress risk also correlates with the destructive path of Hurricane Andrew, with higher incidences of fetal distress found in areas of highest exposure intensity. Hurricane exposed African-American mothers were more likely to birth distressed infants. The policy implications of in utero costs of natural disaster exposure are discussed.

BMC Public Health 2010; 10:515.

Abstract
Background There is a high prevalence of antepartum depression and low birth weight (LBW) in Bangladesh. In high- and low-income countries, prior evidence linking maternal depressive and anxiety symptoms with infant LBW is conflicting. There is no research on the association between maternal mental disorders and LBW in Bangladesh. This study aims to investigate the independent effect of maternal antepartum depressive and anxiety symptoms on infant LBW among women in a rural district of Bangladesh. Methods A population-based sample of 720 pregnant women from two rural subdistricts was assessed for symptoms of antepartum depression, using the Edinburgh Postpartum Depression Scale (EPDS), and antepartum anxiety, using the State Trait Anxiety Inventory (STAI), and followed for 6-8 months postpartum. Infant birth weight of 583 (81%) singleton live babies born at term (≥37 weeks of pregnancy) was measured within 48 hours of delivery. Baseline data provided socioeconomic, anthropometric, reproductive, obstetric, and social support information. Trained female interviewers carried out structured interviews. Chi-square, Fisher's exact, and independent-sample t tests were done as descriptive statistics, and a multiple logistic regression model was used to identify predictors of LBW. Results After adjusting for potential confounders, depressive (OR = 2.24; 95% CI 1.37-3.68) and anxiety (OR = 2.08; 95% CI 1.30-3.25) symptoms were significantly associated with LBW (≤2.5 kg). Poverty, maternal malnutrition, and support during pregnancy were also associated with LBW. Conclusions This study provides evidence that maternal depressive and anxiety symptoms during pregnancy predict the LBW of newborns and replicates results found in other South Asian countries. Policies aimed at the detection and effective management of depressive and anxiety symptoms during pregnancy may reduce the burden on mothers and also act as an important measure in the prevention of LBW among offspring in Bangladesh.

Abstract
Maternal psychosocial stress is an important risk factor for preterm birth, but support interventions have largely been unsuccessful. The objective of this study is to assess how support during pregnancy influences preterm birth risk and possibly ameliorates the effects of chronic stress, life event stress, or pregnancy anxiety in pregnant women. We examined 1,027 singleton preterm births and 1,282 full-term normal weight controls from a population-based retrospective case-control study of Los Angeles County, California women giving birth in 2003, a mostly Latina population (both US-born and immigrant). We used logistic regression to assess whether support from the baby's father during pregnancy influences birth outcomes and effects of chronic stress, pregnancy anxiety, and life event stress. Adjusted odds of preterm birth decreased with better support (OR 0.73 [95%CI 0.52, 1.01]). Chronic stress (OR 1.46 [95%CI 1.11, 1.92]), low confidence of a normal birth (OR 1.57 [95% CI 1.17, 2.12]), and fearing for the baby's health (OR 1.67 [95%CI 1.30, 2.14]) increased preterm birth risk, but life events showed no association. Our data also suggested that paternal support may modify the effect of chronic stress on the risk of preterm birth, such that among mothers lacking support, those with moderate-to-high stress were at increased odds of delivering preterm (OR 2.15 [95%CI 0.92, 5.03]), but women with greater support had no increased risk with moderate-to-high chronic stress (OR 1.13 [95%CI 0.94, 1.35]). Paternal support may moderate the effects of chronic stress on the risk of preterm delivery.

Abstract
Women who have delivered an infant between 16 and 36 weeks' gestation have an increased risk of preterm birth in subsequent pregnancies. The risk increases with more than 1 preterm birth and is inversely proportional to the gestational age of the previous preterm birth. African American women have rates of recurrent preterm birth that are nearly twice that of women of other backgrounds. An approximate risk of recurrent preterm birth can be estimated by a comprehensive reproductive history, with emphasis on maternal race, the number and gestational age of prior births, and the sequence of events preceding the index preterm birth. Interventions including smoking cessation, eradication of asymptomatic bacteriuria, progestational agents, and cervical cerclage can reduce the risk of recurrent preterm birth when employed appropriately.

Abstract
BACKGROUND Studies consistently show a relationship between social disadvantage and low birthweight. Many countries have programs offering special assistance to women thought to be at risk for giving birth to a low birthweight infant. These programs may include advice and counseling (about nutrition, rest, stress management, alcohol, and recreational drug use), tangible assistance (e.g., transportation to clinic appointments, household help), and emotional support. The programs may be delivered by multidisciplinary teams of health professionals, specially trained lay workers, or combination of lay and professional workers. OBJECTIVES The primary objective was to assess effects of programs offering additional social support compared with routine care, for pregnant women believed at high risk for giving birth to babies that are either preterm or weigh less than 2500 gm, or both, at birth. Secondary objectives were to determine whether effectiveness of support was mediated by timing of onset (early versus later in pregnancy) or type of provider (healthcare professional or lay woman). SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2010). SELECTION CRITERIA Randomized trials of additional support during at-risk pregnancy by either a professional (social worker, midwife, or nurse) or specially trained lay person, compared to routine care. We defined additional support as some form of emotional support (e.g., counseling, reassurance, sympathetic listening) and information or advice or both, either in home visits or during clinic appointments, and could include tangible assistance (e.g., transportation to clinic appointments, assistance with care of other children at home). DATA COLLECTION AND ANALYSIS Two review authors evaluated methodological quality. We performed double data entry. MAIN RESULTS We included 17 trials (12,264 women). Programs offering additional social support for at-risk pregnant women were not associated with improvements in any perinatal outcomes, but there was a reduction in the likelihood of antenatal hospital admission (three trials; n = 737; RR 0.79, 95% CI 0.68 to 0.92) and caesarean birth (nine trials; n = 4522; RR 0.87, 95% CI 0.78 to 0.97). AUTHORS' CONCLUSIONS Pregnant women need the support of caring family members, friends, and health professionals. While programs which offer additional support during pregnancy are unlikely to prevent the pregnancy from resulting in a low birthweight or preterm baby, they may be helpful in reducing the likelihood of antenatal hospital admission and caesarean birth.

Abstract
PURPOSE To review the management of pregnancy after an unexplained stillbirth. EPIDEMIOLOGY Approximately 1 in 200 pregnancies will end in stillbirth, of which about one-third will remain unexplained. Unexplained stillbirth is the largest single contributor to perinatal mortality. Subsequent pregnancies do not appear to have an increased risk of stillbirth, but are characterized by increased rates of intervention (induction of labor, elective cesarean section) and iatrogenic adverse outcomes (low birth weight, prematurity, emergency cesarean section and post-partum hemorrhage). CONCLUSIONS There is no level-one evidence to guide management in this situation. Pre-pregnancy counseling is very important to detect and correct potential risk factors such as obesity, smoking and maternal disease. As timely delivery is the mainstay of management, early accurate determination of gestational age is vital. There is controversy regarding the pattern of surveillance, but evidence exists only for ultrasound and not for regular non-stress testing, nor formal fetal movement charting. There is an urgent need for more studies in this important area.

Abstract
Complications of prematurity surpass congenital malformations as the leading cause of infant mortality in the United States. Since 1990, there has been a steady rise in preterm birth, alarming health professionals from all disciplines. This review from a prenatal perspective confirms those concerns and describes the risks and opportunities that may attend efforts to improve the health of fetuses, newborns, and infants. Fetal and live-born outcomes are included.

Abstract
BACKGROUND The vast majority of global stillbirths occur in low- and middle-income countries, and in many settings, the majority of stillbirths occur antenatally, prior to the onset of labour. Poor nutritional status, lack of antenatal care and a number of behaviours increase women's risk of stillbirth in many resource-poor settings. Interventions to reduce these risks could reduce the resulting burden of stillbirths, but the evidence for the impact of such interventions has not yet been comprehensively evaluated. METHODS This second paper of a systematic review of interventions that could plausibly impact stillbirth rates covers 12 different interventions relating to behavioural and socially mediated risk factors, including exposures to harmful practices and substances, antenatal care utilisation and quality, and maternal nutrition before and during pregnancy. The search strategy reviewed indexed medical journals on PubMed and the Cochrane Library. If any eligible randomised controlled trials were identified that were published after the most recent Cochrane review, they were added to generate new meta-analyses. Interventions covered in this paper have a focus on low- and middle-income countries, both because of the large burden of stillbirths and because of the high prevalence of risk factors including maternal malnutrition and harmful environmental exposures. The reviews and studies belonging to these interventions were graded and conclusions derived about the evidence of benefit of these interventions. RESULTS From a programmatic perspective, none of the interventions achieved clear evidence of benefit. Evidence for some socially mediated risk factors were identified, such as exposure to indoor air pollution and birth spacing, but still require the development of appropriate interventions. There is a need for additional studies on culturally appropriate behavioural interventions and clinical trials to increase smoking cessation and reduce exposure to smokeless tobacco. Balanced protein-energy supplementation was associated with reduced stillbirth rates, but larger well-designed trials are required to confirm findings. Peri-conceptional folic acid supplementation significantly reduces neural tube defects, yet no significant associated reductions in stillbirth rates have been documented. Evidence for other nutritional interventions including multiple micronutrient and Vitamin A supplementation is weak, suggesting the need for further research to assess potential of nutritional interventions to reduce stillbirths. CONCLUSION Antenatal care is widely used in low- and middle-income countries, and provides a natural facility-based contact through which to provide or educate about many of the interventions we reviewed. The impact of broader socially mediated behaviors, such as fertility decision-making, access to antenatal care, and maternal diet and exposures like tobacco and indoor air pollution during pregnancy, are poorly understood, and further research and appropriate interventions are needed to test the association of these behaviours with stillbirth outcomes. For most nutritional interventions, larger randomised controlled trials are needed which report stillbirths disaggregated from composite perinatal mortality. Many antepartum stillbirths are potentially preventable in low- and middle-income countries, particularly through dietary and environmental improvement, and through improving the quality of antenatal care - particularly including diagnosis and management of high-risk pregnancies - that pregnant women receive.

Abstract
BACKGROUND Although a number of antenatal and intrapartum interventions have shown some evidence of impact on stillbirth incidence, much confusion surrounds ideal strategies for delivering these interventions within health systems, particularly in low-/middle-income countries where 98% of the world's stillbirths occur. Improving the uptake of quality antenatal and intrapartum care is critical for evidence-based interventions to generate an impact at the population level. This concluding paper of a series of papers reviewing the evidence for stillbirth interventions examines the evidence for community and health systems approaches to improve uptake and quality of antenatal and intrapartum care, and synthesises programme and policy recommendations for how best to deliver evidence-based interventions at community and facility levels, across the continuum of care, to reduce stillbirths. METHODS We systematically searched PubMed and the Cochrane Library for abstracts pertaining to community-based and health-systems strategies to increase uptake and quality of antenatal and intrapartum care services. We also sought abstracts which reported impact on stillbirths or perinatal mortality. Searches used multiple combinations of broad and specific search terms and prioritised rigorous randomised controlled trials and meta-analyses where available. Wherever eligible randomised controlled trials were identified after a Cochrane review had been published, we conducted new meta-analyses based on the original Cochrane criteria. RESULTS In low-resource settings, cost, distance and the time needed to access care are major barriers for effective uptake of antenatal and particularly intrapartum services. A number of innovative strategies to surmount cost, distance, and time barriers to accessing care were identified and evaluated; of these, community financial incentives, loan/insurance schemes, and maternity waiting homes seem promising, but few studies have reported or evaluated the impact of the wide-scale implementation of these strategies on stillbirth rates. Strategies to improve quality of care by upgrading the skills of community cadres have shown demonstrable impact on perinatal mortality, particularly in conjunction with health systems strengthening and facilitation of referrals. Neonatal resuscitation training for physicians and other health workers shows potential to prevent many neonatal deaths currently misclassified as stillbirths. Perinatal audit systems, which aim to improve quality of care by identifying deficiencies in care, are a quality improvement measure that shows some evidence of benefit for changes in clinical practice that prevent stillbirths, and are strongly recommended wherever practical, whether as hospital case review or as confidential enquiry at district or national level. CONCLUSION Delivering interventions to reduce the global burden of stillbirths requires action at all levels of the health system. Packages of interventions should be tailored to local conditions, including local levels and causes of stillbirth, accessibility of care and health system resources and provider skill. Antenatal care can potentially serve as a platform to deliver interventions to improve maternal nutrition, promote behaviour change to reduce harmful exposures and risk of infections, screen for and treat risk factors, and encourage skilled attendance at birth. Following the example of high-income countries, improving intrapartum monitoring for fetal distress and access to Caesarean section in low-/middle-income countries appears to be key to reducing intrapartum stillbirth. In remote or low-resource settings, families and communities can be galvanised to demand and seek quality care through financial incentives and health promotion efforts of local cadres of health workers, though these interventions often require simultaneous health systems strengthening. Perinatal audit can aid in the development of better standards of care, improving quality in health systems. Effective strategies to prevent stillbirth are known; gaps remain in the data, the evidence and perhaps most significantly, the political will to implement these strategies at scale.

[PMID: 18765164 PMCID: PMC2654337 DOI: 10.1016/j.jad.2008.07.015] [Citation(s) in RCA: 44] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2008] [Revised: 07/14/2008] [Accepted: 07/14/2008] [Indexed: 01/11/2023]
Abstract
BACKGROUND Strong social support has been linked with positive mental health and better birth outcomes for pregnant women. Our aim was to replicate the psychometric properties of the Kendler Social Support Interview modified for use in pregnant women and to establish the inventory's relationship to depression in pregnancy. METHODS The modified Kendler Social Support Interview (MKSSI) was evaluated using principal components analysis. The association with depression was used as an indicator of external validity and was assessed by logistic regression. RESULTS Data from 783 subjects were analyzed. One large principal component, termed "global support," (eigenvalue=6.086) represented 22.5% of the total variance. However, 6 of the 27 items (frequency of contact with spouse, siblings, other relatives, and friends, and attendance at church and clubs) had low levels of association (<0.4) and thus were excluded from suggested items for a total score. Varimax rotation of the remaining 21 items resulted in subscales that fell into expected groupings: mother, father, siblings, friends, etc. One unit and two unit increases in the global support score were associated with 58.3% (OR=0.417, 95% CI=0.284-0.612) and 82.6% (OR=0.174, 95% CI=0.081-0.374) reductions in odds for depression, respectively. LIMITATIONS The ability of this social support scale to predict future depression in pregnancy has not yet been established due to cross-sectional design. CONCLUSION The MKSSI is reliable and valid for use in evaluating social support and its relationship to depression in pregnant women.

Abstract
Although significant progress has been made to increase prenatal care access, national organizations concerned with health equity emphasize that eliminating disparities will require greater attention to quality of care, assessed from both the biomedical and patient perspectives. In this study, we examined narratives about pregnancy experiences from low-income primiparous African American, Mexican American, Puerto Rican, and White women who participated in focus groups conducted in 1996. We reanalyzed transcripts from these discussions, extracting passages in which women talked about the content and quality of their prenatal care experiences. Data were mapped to four domains reflecting patient-centeredness markers identified in the 2005 U.S. National Healthcare Disparities Report (NHDR). These markers include the extent to which the women perceived that their provider listened carefully, explained things, showed respect, and spent enough time with them. The narratives provided by the study participants suggest a critical and intuitive understanding of the NHDR patient-centeredness markers and some shared understanding across cultural groups. Implications for improving quality and its measurement in prenatal care are discussed.

Abstract
OBJECTIVES We tested the effect of nurse-delivered telephone individualized social support ("Baby BEEP") and eight mailed prenatal smoking cessation booklets singly and in combination (2 x 2 factorial design) on smoking cessation in low-income rural pregnant women (N = 695; 75% participation). METHODS Participants randomized to Baby BEEP groups (n = 345) received weekly calls throughout pregnancy plus 24-7 beeper access. Saliva cotinine samples were collected monthly from all groups by other nurses at home visits up to 6 weeks post-delivery. Primary outcomes were point prevalence abstinence (cotinine < 30 ng/ml) in late pregnancy and post-delivery. RESULTS Only 47 women were lost to follow-up. Intent-to-treat analyses showed no difference across intervention groups (17-22%, late pregnancy; 11-13.5%, postpartum), and no difference from the controls (17%, late pregnancy; 13%, postpartum). Post hoc analyses of study completers suggested a four percentage-point advantage for the intervention groups over controls in producing early and mid-pregnancy continuous abstainers. Partner smoking had no effect on late pregnancy abstinence (OR = 1.7, 95% CI = 0.95, 3.2), but post-delivery, the effect was pronounced (OR = 3.2, 95% CI = 1.8, 5.9). CONCLUSIONS High abstinence rates in the controls indicate the power of biologic monitoring and home visits to assess stress, support, depression, and intimate partner violence; these elements plus booklets were as effective as more intensive interventions. Targeting partners who smoke is needed.

Abstract
OBJECTIVES Community-based prenatal case management (PCM) is a means to improve birth outcomes for medically or socially high-risk pregnant women. To conduct national surveys of PCM programs, a useful sampling frame of existing programs is needed. However, as a relatively small optional Medicaid reimbursed program, PCM programs are hard to reach. Methodological approaches are needed to address issues arising when attempting to access and survey hard-to-reach participants, including programs. METHODS State Medicaid offices were contacted to determine whether they reimbursed for PCM, and lists of Medicaid providers were obtained from those states. Most providers on the lists were contacted to confirm that they provide PCM and to verify the program director contact information. FINDINGS Multiple attempts, using different modes of communication, were required to identify states reimbursing for PCM through Medicaid (n = 33). Of providers on the lists obtained from 29 of the 33 states, 34% of those listed provided PCM, suggesting over coverage rather than omissions. Provider contact information was outdated, duplicative, or not specific to PCM. The final count was 1,184 PCM programs in 29 states. CONCLUSION Identifying hard-to-reach programs requires persistence and creativity, as well as a rigorous approach to generating a census of programs.

Abstract
Interventions to reduce the morbidity and mortality of preterm birth can be primary (directed to all women), secondary (aimed at eliminating or reducing existing risk), or tertiary (intended to improve outcomes for preterm infants). Most efforts so far have been tertiary interventions, such as regionalised care, and treatment with antenatal corticosteroids, tocolytic agents, and antibiotics. These measures have reduced perinatal morbidity and mortality, but the incidence of preterm birth is increasing. Advances in primary and secondary care, following strategies used for other complex health problems, such as cervical cancer, will be needed to prevent prematurity-related illness in infants and children.

Abstract
OBJECTIVE to explore midwives' views of psychosocial well-being in the postnatal period. DESIGN qualitative study using focus-group interviews conducted in 1999. SETTING two community health centres and a school of nursing and midwifery in Scotland. PARTICIPANTS a convenience sample of community and student midwives. ANALYSIS thematic analysis was undertaken through the identification of codes, categories and themes. FINDINGS the categories were generated from the interview questions: 'the meaning midwives give to women's psychosocial well-being', 'midwives' assessment of women's well-being', and 'midwives views of worrying behaviours' displayed by women. From the first two categories, themes of 'coping', 'expectations', 'observation and communication skills', 'labour debriefing', and 'previous contact with women' emerged. Midwives assessed coping and unmet expectations through a range of communication and observational skills, including the use of a form of labour debriefing. Midwives who knew women during their pregnancy thought that they were able to assess coping and expectations better in the postnatal period. The midwives tended to describe women using stereotypical categories. From the third category, 'worrying behaviours', three themes emerged; 'extreme or obsessive behaviours about self, the baby or house' 'wanting to detain you' and 'quiet women'. CONCLUSIONS the meaning midwives give to psychosocial well-being includes a complex interplay between midwives' views of psychosocial well-being and their assessment of it. The importance midwives give to knowing women in pregnancy has implications for the ongoing debate about the provision of continuity of carer. Midwives used a range of techniques to elicit accurate information, to confirm problems or be reassured that all was well. Views based on stereotypical generalisations should be challenged.

Abstract
BACKGROUND Historically, women have been attended and supported by other women during labour. However, in recent decades in hospitals worldwide, continuous support during labour has become the exception rather than the routine. Concerns about the consequent dehumanization of women's birth experiences have led to calls for a return to continuous support by women for women during labour. OBJECTIVES Primary: to assess the effects, on mothers and their babies, of continuous, one-to-one intrapartum support compared with usual care. Secondary: to determine whether the effects of continuous support are influenced by: (1) routine practices and policies in the birth environment that may affect a woman's autonomy, freedom of movement and ability to cope with labour; (2) whether the caregiver is a member of the staff of the institution; and (3) whether the continuous support begins early or later in labour. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (February 2007). SELECTION CRITERIA All published and unpublished randomized controlled trials comparing continuous support during labour with usual care. DATA COLLECTION AND ANALYSIS We used standard methods of the Cochrane Collaboration Pregnancy and Childbirth Group. All authors participated in evaluation of methodological quality. One author and a research assistant independently extracted the data. We sought additional information from the trial authors. We used relative risk for categorical data and weighted mean difference for continuous data to present the results. MAIN RESULTS Sixteen trials involving 13,391 women met inclusion criteria and provided usable outcome data. Primary comparison: women who had continuous intrapartum support were likely to have a slightly shorter labour, were more likely to have a spontaneous vaginal birth and less likely to have intrapartum analgesia or to report dissatisfaction with their childbirth experiences. Subgroup analyses: in general, continuous intrapartum support was associated with greater benefits when the provider was not a member of the hospital staff, when it began early in labour and in settings in which epidural analgesia was not routinely available. AUTHORS' CONCLUSIONS All women should have support throughout labour and birth.

Abstract
BACKGROUND Examining women's preferences for maternity care is overdue. Understanding women's preferences and re-orienting services to meet their expectations is critical to improving health outcomes. METHOD A self-report survey of a convenience community sample of 63 women visiting a Maternity Coalition/Association for Improvements in Maternity Services stall at a Mother and Baby Expo in 2003. RESULTS Over 95% of women ranked birth safety, bonding with the baby, feeling in control during birth, and postnatal care as "very important". Over 85% of women rated educational preparation for birth, the relationship with their caregiver, prenatal care, and breastfeeding successfully as "very important". Avoiding labour pain was considered less important by more women than any other item. Around half the respondents preferred their birth care to be from a chosen midwife with access to medical backup (57.9%, n=37). Some women identified a lack of choice of care options with 45.9% (n=17) reporting "little" or "no" choice in birth care for their previous birth. Poor quality care was also identified with 57.9% (n=22) rating their postnatal care as "mediocre". Given assurance of equal safety and free care, 50% (n=31) of participants would prefer to give birth at a birth centre and 24.2% (15 out of 63) would prefer a homebirth. CONCLUSION Factors associated with safety, control, continuity of care and successful mothering are perceived as important for many women. Some women perceived limited birth choices. More needs be done to align the provision of maternity services with women's preferred care options. Given the small self-select, non-representative sample, results should be interpreted with caution.

Abstract
BACKGROUND Despite efforts to assure high methodological standards, systematic reviews may be affected by publication bias. The objective of this study was to evaluate the occurrence of publication bias in a collection of high quality systematic reviews on reproductive health. METHODS Systematic reviews included in the Reproductive Health Library (RHL), issue No 9, were assessed. Funnel plot was used to assess meta-analyses containing 10 or more trials reporting a binary outcome. A funnel plot, the estimated number of missing studies and the adjusted combined effect size were obtained using the "trim and fill method". Meta-analyses results that were not considered to be robust due to a possible publication bias were submitted to a more detailed assessment. RESULTS A total of 21 systematic reviews were assessed. The number of trials comprising each one ranged from 10 to 83 (median = 13), totaling 379 trials, whose results have been summarized. None of the reviews had reported any evaluation of publication bias or funnel plot asymmetry. Some degree of asymmetry in funnel plots was observed in 18 of the 21 meta-analyses evaluated (85.7%), with the estimated number of missing studies ranging from 1 to 18 (median = 3). Only for three meta-analyses, the conclusion could not be considered robust due to a possible publication bias. CONCLUSION Asymmetry is a frequent finding in funnel plots of meta-analyses in reproductive health, but according to the present evaluation, less than 15% of meta-analyses report conclusions that would not be considered robust. Publication bias and other sources of asymmetry in funnel plots should be systematically addressed by reproductive health meta-analysts. Next amendments in Cochrane systematic reviews should include this type of evaluation. Further studies regarding the evolution of effect size and publication bias over time in systematic reviews in reproductive health are needed.

Abstract
STUDY OBJECTIVE To compare the continuous knotless technique of perineal repair with the interrupted method after spontaneous vaginal birth DESIGN A randomized controlled trial. DESIGN CLASSIFICATION Canadian Task Force Classification I. SETTING This study was undertaken in a university hospital with more than 2200 deliveries per year. The static population of this district includes a wide range of socioeconomic classes and is predominately white. PATIENTS From May 1 to November 19, 2003, 214 primiparous women with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous knotless technique (CKT; n=107) or the interrupted technique (IT; n=107) suturing method. INTERVENTIONS The interrupted technique (IT) involves placing 3 layers of sutures whereas the continuous knotless technique (CKT) involves reapproximating vaginal trauma, perineal muscles, and skin with a loose, continuous, nonlocking technique. MEASUREMENTS AND MAIN RESULTS The primary outcomes of the study were perineal pain (evaluated by visual analogue scale) at 48 hours and day 10 and dyspareunia 3 months after delivery. Secondary outcomes included suture removal, wound dehiscence, analgesia use up to 48 hours, and satisfaction with repair established at 3 and 12 months after childbirth. At day 10, 19 women had dropped out of the study. Significantly fewer women reported pain at 10 days with the CKT than with the IT (32.3% vs 60.4%; p<.001). Analgesia use up to 48 hours postpartum was less in the CKT group than in the IT group (33.6% vs 54.2%; p<.05). No difference was found in superficial dyspareunia at 3 months for the CKT versus the IT group. CONCLUSION The use of a continuous knotless technique for perineal repair is associated with less short-term pain than techniques with interrupted sutures.

Abstract
OBJECTIVES In the mid 1980's the federal government passed legislation allowing states to expand their Medicaid programs for pregnant women. States were also offered matching funds for "enhanced" prenatal care services. The Illinois Family Case Management (FCM) Program targets low-income women and aims to reduce barriers to prenatal care and infant healthcare utilization and also provides health education. We evaluated the outcome of the Illinois Family Case Management Program (FCM) in preventing low birth weight in Winnebago County. METHODS A total of 6,440 participants were included in this study. Logistic regression was used to test whether number of visits or total hours of visitation were significant protective factors against low birth weight. RESULTS While participating in the FCM Program resulted in a lower rate of low birth weight delivery, neither increasing time with a family case manager nor increasing number of visits showed statistically significant additional protection against low birth weight delivery after adjustment for potential confounding factors. CONCLUSION In order to further improve program outcomes, efforts need to include improving quality of interventions or developing new interventions rather than simply increasing the amount of current intervention for each participant. The cost effectiveness of shifting FCM Program efforts away from infants (aged 0-1 year) towards improved prenatal interventions should be evaluated.

Abstract
Smoking in pregnancy is a major determinant of low birthweight and a range of adverse infant health outcomes. There is a well-established social gradient in smoking in pregnancy in the US and northern Europe. Social gradients in health-related behaviours may result from longitudinal accumulation and cross-sectional clustering of social risk exposures. There is, however, no published confirmation of this explanation in empirical data with smoking in pregnancy as the outcome. This study aimed to test the effects of longitudinal accumulation and cross-sectional clustering of social risk exposures on smoking in pregnancy using data on the first pregnancies of 3163 female members of the 1958 British national cohort. Social class at birth and aged 11 years was used to create three dichotomous variables representing cumulative social class (both manual, one manual and one non-manual, both non-manual) early in the lifecourse. Cross-sectional clustering of social risk was represented by four dichotomous variables created from combinations of maternal age (<20 vs. 20+), own social class (manual vs. non-manual) and educational attainment (low vs. other). Cumulative social class in early childhood was associated with smoking in pregnancy in bivariate analysis but not after adjustment for cross-sectional clustering of social risk exposures. However, women who had been in the manual social groups at birth and 11 years were at increased risk of cross-sectional clustering of social risk exposures around pregnancy suggesting a pathway from early lifecourse risk exposure to social risk factors associated with a high risk of smoking in pregnancy. These findings suggest that the social gradient in smoking in pregnancy results from longitudinal accumulation and cross-sectional clustering of social risk exposures. Interventions aimed at reducing social inequalities in smoking in pregnancy need to account for cumulative and cross-sectionally clustered effects of social risk exposures.

Abstract
BACKGROUND Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain and is widely used as a form of pain relief in labour. However, there are concerns regarding unintended adverse effects on the mother and infant. OBJECTIVES To assess the effects of all modalities of epidural analgesia (including combined -spinal-epidural) on the mother and the baby, when compared with non-epidural or no pain relief during labour. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group Trials Register (June 2005). SELECTION CRITERIA Randomised controlled trials comparing all modalities of epidural with any form of pain relief not involving regional blockade, or no pain relief in labour. DATA COLLECTION AND ANALYSIS Two of the review authors independently assessed trials for eligibility, methodological quality and extracted all data. Data were entered into RevMan and double checked. Primary analysis was by intention-to-treat; sensitivity analyses excluded trials with > 30% of women receiving un-allocated treatment. MAIN RESULTS Twenty-one studies involving 6664 women were included, all but one study compared epidural analgesia with opiates. For technical reasons, data on women's perception of pain relief in labour could only be included from one study which found epidural analgesia to offer better pain relief than non-epidural analgesia (weighted mean difference (WMD) -2.60, 95% confidence interval (CI) -3.82 to -1.38, 1 trial, 105 women). However, epidural analgesia was associated with an increased risk of instrumental vaginal birth (relative risk (RR) 1.38, 95% CI 1.24 to 1.53, 17 trials, 6162 women). There was no evidence of a significant difference in the risk of caesarean delivery (RR 1.07, 95% CI 0.93 to 1.23, 20 trials, 6534 women), long-term backache (RR 1.00, 95% CI 0.89 to 1.12, 2 trials, 814 women), low neonatal Apgar scores at five minutes (RR 0.70, 95% CI 0.44 to 1.10, 14 trials, 5363 women), and maternal satisfaction with pain relief (RR 1.18 95% CI 0.92 to 1.50, 5 trials, 1940 women). No studies reported on rare but potentially serious adverse effects of epidural analgesia. AUTHORS' CONCLUSIONS Epidural analgesia appears to be effective in reducing pain during labour. However, women who use this form of pain relief are at increased risk of having an instrumental delivery. Epidural analgesia had no statistically significant impact on the risk of caesarean section, maternal satisfaction with pain relief and long-term backache and did not appear to have an immediate effect on neonatal status as determined by Apgar scores. Further research may be helpful to evaluate rare but potentially severe adverse effects of epidural analgesia on women in labour and long-term neonatal outcomes.
