Stillbirth rates in low-middle income countries 2010 - 2013: a population-based, multi-country study from the Global Network

Improving pregnancy outcomes in low- and middle-income countries

This paper reviews the very large discrepancies in pregnancy outcomes between high, low and middle-income countries and then presents the medical causes of maternal mortality, stillbirth and neonatal mortality in low-and middle-income countries. Next, we explore the medical interventions that were associated with the very rapid and very large declines in maternal, fetal and neonatal mortality rates in the last eight decades in high-income countries. The medical interventions likely to achieve similar declines in pregnancy-related mortality in low-income countries are considered. Finally, the quality of providers and the data to be collected necessary to achieve these reductions are discussed. It is emphasized that single interventions are unlikely to achieve important reductions in pregnancy-related mortality. Instead, improving the overall quality of pregnancy-related care across the health-care system will be necessary. The conditions that cause maternal mortality also cause stillbirths and neonatal deaths. Focusing on all three mortalities together is likely to have a larger impact than focusing on one of the mortalities alone.

Pregnancy-related morbidity and risk factors for fatal foetal outcomes in the Taabo health and demographic surveillance system, Côte d'Ivoire

Background

Reliable, population-based data on pregnancy-related morbidity and mortality, and risk factors for fatal foetal outcomes are scarce for low- and middle-income countries. Yet, such data are essential for understanding and improving maternal and neonatal health and wellbeing.

Methods

Within the 4-monthly surveillance rounds of the Taabo health and demographic surveillance system (HDSS) in south-central Côte d’Ivoire, all women of reproductive age identified to be pregnant between 2011 and 2014 were followed-up. A questionnaire pertaining to antenatal care, pregnancy-related morbidities, delivery circumstances, and birth outcome was administered to eligible women. Along with sociodemographic information retrieved from the Taabo HDSS repository, these data were subjected to penalized maximum likelihood logistic regression analysis, to determine risk factors for fatal foetal outcomes.

Results

A total of 2976 pregnancies were monitored of which 118 (4.0%) resulted in a fatal outcome. Risk factors identified by multivariable logistic regression analysis included sociodemographic factors of the expectant mother, such as residency in a rural area (adjusted odds ratio (aOR) = 2.87; 95% confidence interval (CI) 1.31–6.29) and poorest wealth tertile (aOR = 1.79; 95% CI 1.02–3.14), a history of miscarriage (aOR = 23.19; 95% CI 14.71–36.55), non-receipt of preventive treatment such as iron/folic acid supplementation (aOR = 3.15; 95% CI 1.71–5.80), only two doses of tetanus vaccination (aOR = 2.59; 95% CI 1.56–4.30), malaria during pregnancy (aOR = 1.94; 95% CI 1.21–3.11), preterm birth (aOR = 4.45; 95% CI 2.82–7.01), and delivery by caesarean section (aOR = 13.03; 95% CI 4.24–40.08) or by instrumental delivery (aOR = 5.05; 95% CI 1.50–16.96). Women who paid for delivery were at a significantly lower odds of a fatal foetal outcome (aOR = 0.39; 95% CI 0.25–0.74).

Conclusions

We identified risk factors for fatal foetal outcomes in a mainly rural HDSS site of Côte d’Ivoire. Our findings call for public health action to improve access to, and use of, quality services of ante- and perinatal care.

The fetuses-at-risk approach: survival analysis from a fetal perspective

Several phenomena in contemporary perinatology create challenges for analyzing pregnancy outcomes. These include recent increases in iatrogenic delivery at late preterm and early term gestation, which are incongruent with the belief that stillbirth and neonatal death risks decrease exponentially with advancing gestational age. Perinatal epidemiologists have also puzzled over the paradox of intersecting birthweight-specific and gestational age-specific perinatal mortality curves for decades. For example, neonatal mortality rates among preterm infants of women who smoke are substantially lower than neonatal mortality rates among preterm infants of non-smoking women, whereas the reverse pattern occurs at term gestation. This mortality crossover is observed across several contrasts (for example, women with hypertensive disorders of pregnancy vs. normotensive women, older vs. younger women, twins vs. singletons) and outcomes (stillbirth, neonatal death, sudden infant death syndrome and cerebral palsy), and irrespective of how advancing "maturity" is defined (birthweight or gestational age). One approach proposed to address and explain these unexpected phenomena is the fetuses-at-risk model. This formulation involves a reconceptualization of the denominator for perinatal outcome rates from births to surviving fetuses. In this overview of the fetuses-at-risk model, we discuss the central tenets of the births-based and the fetuses-based formulations. We also describe the extension of the fetuses-at-risk approach to outcomes into and beyond the neonatal period and to a multivariable adaptation. Finally, we provide a substantive context by discussing biological mechanisms underlying the fetuses-at-risk model and contemporary obstetric phenomena that are better understood from that model than from one based on births.

Potentially Preventable Stillbirth in a Diverse U.S. Cohort

OBJECTIVE

To estimate the proportion of potentially preventable stillbirths in the United States.

METHODS

We conducted a secondary analysis of 512 stillbirths with complete evaluation enrolled in the Stillbirth Collaborative Research Network from 2006 to 2008. The Stillbirth Collaborative Research Network was a multisite, geographically, racially, and ethnically diverse, population-based case-control study of stillbirth in the United States. Cases of stillbirth underwent standard evaluation that included maternal interview, medical record abstraction, biospecimen collection, postmortem examination, placental pathology, and clinically recommended evaluation. Each stillbirth was assigned probable and possible causes of death using the Initial Causes of Fetal Death algorithm system. For this analysis, we defined potentially preventable stillbirths as those occurring in nonanomalous fetuses, 24 weeks of gestation or greater, and weighing 500 g or greater that were 1) intrapartum, 2) the result of medical complications, 3) the result of placental insufficiency, 4) multiple gestation (excluding twin-twin transfusion), 5) the result of spontaneous preterm birth, or 6) the result of hypertensive disorders of pregnancy.

RESULTS

Of the 512 stillbirths included in our cohort, causes of potentially preventable stillbirth included placental insufficiency (65 [12.7%]), medical complications of pregnancy (31 [6.1%]), hypertensive disorders of pregnancy (20 [3.9%]), preterm labor (16 [3.1%]), intrapartum (nine [1.8%]), and multiple gestations (four [0.8%]). Twenty-seven stillbirths fit two or more categories, leaving 114 (22.3%) potentially preventable stillbirths.

CONCLUSION

Based on our definition, almost one fourth of stillbirths are potentially preventable. Given the predominance of placental insufficiency among stillbirths, identification and management of placental insufficiency may have the most immediate effect on stillbirth reduction.

Level, causes, and risk factors of stillbirth: a population-based case control study from Chandigarh, India

Background

Globally, India ranks first in the absolute number of stillbirths. Hence, the level, causes, and risk factors of stillbirths were estimated to facilitate designing of prevention strategy.

Methods

Capture and recapture method was used to identify 301 stillbirths from 1st July 2013 to 31st August 2014 in Chandigarh Union Territory of India. Verbal autopsies (n = 181) were done at household level to identify causes of stillbirths. Risk factors were determined using case-control approach. Women who had a stillbirth in the past 3 months were enrolled as cases (n = 181) and those who had live-birth in same neighbourhood were included as controls (n = 181). Statistical differences in the distribution of characteristics of cases and controls were tested by t test and chi square test respectively for quantitative and categorical variables. In logistic regression models adjusted odds ratios (aOR) and 95% confidence intervals (CIs) were estimated for various risk factors.

Results

Stillbirth rate was estimated to be 16/1000 birth. Antepartum causes were more common (68%) than intrapartum causes (32%). Among maternal conditions, hypertension (18.2%) and chorio-amnionitis (13.8%), and among foetal conditions, growth restriction (19.9%) and congenital anomalies (18.8%) were the leading causes. In about half of the stillbirths foetal (48%) and maternal (44.7%) causes were unidentifiable. Risk factors of stillbirths were: higher maternal age (aOR 1.1, 95%CI 1.0–1.2), vaginal delivery (aOR 8.1, 95%CI 2.6–26), induced labour (aOR 2.6, 95%CI 1.5–4.5), green or light brown liquor (aOR 2.0, 95%CI 1.1–3.8), preterm delivery (aOR 6.4, 95%CI 3.7–11) and smaller household size (aOR 1.2, 95% CI 1.1–1.3).

Conclusions

Stillbirth rate was high in Chandigarh Union Territory of India. Major causes and risk factors amenable to interventions were infections, hypertension, congenital malformations, foetal growth restriction, pre-maturity and household size. Therefore, better maternity ante-natal and intra-natal care is required to achieve a single digit stillbirth rate.

Patterns and risk factors of birth defects in rural areas of south-eastern Gabon

Within the context of high neonatal mortality in sub-Saharan Africa, a retrospective study was conducted on the prevalence of congenital malformations and the association between maternal risk factors and birth defects in rural populations of south-eastern Gabon. Two populations were studied: a group of 3500 births recorded in rural area (Koula-Moutou) and a second group of 4212 births in a semi-rural area (Franceville) in Gabon. Our data showed an increasing prevalence in congenital anomalies from rural to urban areas (P < 0.001). Maternal risk factors such as age > 35 years, multiparity and employment status were significantly associated with the levels of stillbirth. Together with abortions and stillbirths, congenital malformations require strong monitoring in rural and urban areas of sub-Saharan Africa.

Ethnically Tibetan women in Nepal with low hemoglobin concentration have better reproductive outcomes

Background and objectives: Tibetans have distinctively low hemoglobin concentrations at high altitudes compared with visitors and Andean highlanders. This study hypothesized that natural selection favors an unelevated hemoglobin concentration among Tibetans. It considered nonheritable sociocultural factors affecting reproductive success and tested the hypotheses that a higher percent of oxygen saturation of hemoglobin (indicating less stress) or lower hemoglobin concentration (indicating dampened response) associated with higher lifetime reproductive success.

Methodology: We sampled 1006 post-reproductive ethnically Tibetan women residing at 3000–4100 m in Nepal. We collected reproductive histories by interviews in native dialects and noninvasive physiological measurements. Regression analyses selected influential covariates of measures of reproductive success: the numbers of pregnancies, live births and children surviving to age 15.

Results: Taking factors such as marriage status, age of first birth and access to health care into account, we found a higher percent of oxygen saturation associated weakly and an unelevated hemoglobin concentration associated strongly with better reproductive success. Women who lost all their pregnancies or all their live births had hemoglobin concentrations significantly higher than the sample mean. Elevated hemoglobin concentration associated with a lower probability a pregnancy progressed to a live birth.

Conclusions and implications: These findings are consistent with the hypothesis that unelevated hemoglobin concentration is an adaptation shaped by natural selection resulting in the relatively low hemoglobin concentration of Tibetans compared with visitors and Andean highlanders.

Willingness to Pay for a Maternity Waiting Home Stay in Zambia

INTRODUCTION

Complications of pregnancy and childbirth can pose serious risks to the health of women, especially in resource-poor settings. Zambia has been implementing a program to improve access to emergency obstetric and neonatal care, including expansion of maternity waiting homes-residential facilities located near a qualified medical facility where a pregnant woman can wait to give birth. Yet it is unclear how much support communities and women would be willing to provide to help fund the homes and increase sustainability.

METHODS

We conducted a mixed-methods study to estimate willingness to pay for maternity waiting home services based on a survey of 167 women, men, and community elders. We also collected qualitative data from 16 focus group discussions to help interpret our findings in context.

RESULTS

The maximum willingness to pay was 5.0 Zambian kwacha or $0.92 US dollars per night of stay. Focus group discussions showed that willingness to pay is dependent on higher quality of services such as food service and suggested that the pricing policy (by stay or by night) could influence affordability and use.

DISCUSSION

While Zambians seem to value and be willing to contribute a modest amount for maternity waiting home services, planners must still address potential barriers that may prevent women from staying at the shelters. These include cash availability and affordability for the poorest households.

Impact of stillbirths on international comparisons of preterm birth rates: a secondary analysis of the WHO multi-country survey of Maternal and Newborn Health

Objective

To evaluate the extent to which stillbirths affect international comparisons of preterm birth rates in low‐ and middle‐income countries.

Design

Secondary analysis of a multi‐country cross‐sectional study.

Setting

29 countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health.

Population

258 215 singleton deliveries in 286 hospitals.

Methods

We describe how inclusion or exclusion of stillbirth affect rates of preterm births in 29 countries.

Main outcome measures

Preterm delivery.

Results

In all countries, preterm birth rates were substantially lower when based on live births only, than when based on total births. However, the increase in preterm birth rates with inclusion of stillbirths was substantially higher in low Human Development Index (HDI) countries [median 18.2%, interquartile range (17.2–34.6%)] compared with medium (4.3%, 3.0–6.7%), and high‐HDI countries (4.8%, 4.4–5.5%).

Conclusion

Inclusion of stillbirths leads to higher estimates of preterm birth rate in all countries, with a disproportionately large effect in low‐HDI countries. Preterm birth rates based on live births alone do not accurately reflect international disparities in perinatal health; thus improved registration and reporting of stillbirths are necessary.

Tweetable abstract

Inclusion of stillbirths increases preterm birth rates estimates, especially in low‐HDI countries.

Inclusion of stillbirths increases preterm birth rates estimates, especially in low‐HDI countries.

Impact of fetal counseling on outcome of antenatal congenital surgical anomalies

AIM

To analyze the impact of counseling on antenatal congenital surgical anomalies (ACSA).

METHODS

Cases presenting with ACSA for fetal counseling and those presenting in post-natal period following diagnosis of ACSA (PACSA) for surgical opinion were analyzed for spectrum, presentation and outcome.

RESULTS

117 cases including ACSA(68);PACSA(49) were analyzed. Gestational age at diagnosis of ACSA;PACSA was 17-37;17-39 weeks (median 24;32 weeks). Diagnoses in ACSA;PACSA included urological (26;31), neurological (10;5), congenital diaphragmatic hernia (CDH)(5;1), gastrointestinal (5;5), lung and chest anomalies (5;1), intraabdominal cysts (4;1), abdominal wall defects (4;0), tumors (3;3), limb anomaly (1;1), esophageal atresia (1;1), conjoint twins (1;0), hepatomegaly (1;0), and major cardiac anomalies (2;0). Two antenatal interventions were done for ACSA; vesicoamniotic shunt and amnioinfusion for oligohydramnios. 17;24 ACSA;PACSA required early surgical intervention in post-natal period. Nine ACSA underwent medical termination of pregnancy and 4 had intrauterine demise. Nine ACSA babies died including two CDH, one gastroschisis, one duodenal atresia, one conjoint twins, one megacystitis with motility disorder and three posterior urethral valves. All PACSA babies survived.

CONCLUSION

Fetal counseling for CSA portrays true outcome of ACSA with 32.3% (22/68) mortality versus 0% for PACSA due to selection bias. However, fetal counseling ensures optimal perinatal care.

Global Network for Women's and Children's Health Research: probable causes of stillbirth in low- and middle-income countries using a prospectively defined classification system

OBJECTIVE

We sought to classify causes of stillbirth for six low-middle-income countries using a prospectively defined algorithm.

DESIGN

Prospective, observational study.

SETTING

Communities in India, Pakistan, Guatemala, Democratic Republic of Congo, Zambia and Kenya.

POPULATION

Pregnant women residing in defined study regions.

METHODS

Basic data regarding conditions present during pregnancy and delivery were collected. Using these data, a computer-based hierarchal algorithm assigned cause of stillbirth. Causes included birth trauma, congenital anomaly, infection, asphyxia, and preterm birth, based on existing cause of death classifications and included contributing maternal conditions.

MAIN OUTCOME MEASURES

Primary cause of stillbirth.

RESULTS

Of 109 911 women who were enrolled and delivered (99% of those screened in pregnancy), 2847 had a stillbirth (a rate of 27.2 per 1000 births). Asphyxia was the cause of 46.6% of the stillbirths, followed by infection (20.8%), congenital anomalies (8.4%) and prematurity (6.6%). Among those caused by asphyxia, 38% had prolonged or obstructed labour, 19% antepartum haemorrhage and 18% pre-eclampsia/eclampsia. About two-thirds (67.4%) of the stillbirths did not have signs of maceration.

CONCLUSIONS

Our algorithm determined cause of stillbirth from basic data obtained from lay-health providers. The major cause of stillbirth was fetal asphyxia associated with prolonged or obstructed labour, pre-eclampsia and antepartum haemorrhage. In the African sites, infection also was an important contributor to stillbirth. Using this algorithm, we documented cause of stillbirth and its trends to inform public health programs, using consistency, transparency, and comparability across time or regions with minimal burden on the healthcare system.

TWEETABLE ABSTRACT

Major causes of stillbirth are asphyxia, pre-eclampsia and haemorrhage. Infections are important in Africa.

Mindfulness-Based Intervention for Perinatal Grief in Rural India: Improved Mental Health at 12 Months Follow-Up

Stillbirth is a significant global health problem that frequently results in perinatal grief with compound negative psychosocial impact. In low-resource settings with exceedingly high stillbirth rates, such as rural Chhattisgarh, India, it is vital to utilize low-cost, effective interventions. Mindfulness-based stress reduction is an evidence-based intervention utilized for a broad range of physical and mental health problems, and is adaptable to specific populations. The objective of this study was to explore the sustained effectiveness of a shortened, culturally adapted mindfulness-based intervention (MBI) designed to address complex grief after stillbirth. We used an observational, mixed-methods pre-post study design with 6-week and 12-month follow-up assessments among women with a history of stillbirth (N = 22). Analyses explored study outcomes and continued use of mindfulness skills. Pretest results showed elevated psychological symptoms and high levels of perinatal grief. General linear modeling repeated measures was used to explore 6-week and 12-month follow-up changes from baseline, controlling for significantly correlated demographic variables. Longitudinal results indicated significant reductions in perinatal grief and psychological symptoms; four of the five facets of mindfulness changed in the desired direction; and resilience scores indicated thriving. The shortened, culturally adapted, MBI pilot brought about sustained, significant reductions of perinatal grief and mental health symptoms, and participants reported use of mindfulness skills in day-to-day life. This study shows that the significant mental health needs among rural women of various castes and ethnicities in Chhattisgarh following stillbirth were successfully addressed by a promising MBI with potential scalability and sustainability.

Maternal and newborn outcomes at a tertiary care hospital in Lusaka, Zambia, 2008-2012

OBJECTIVE

To measure key obstetric and neonatal outcomes recorded at a tertiary hospital in Zambia over a 5-year period.

METHODS

A retrospective analysis was conducted among women who had delivered at the University Teaching Hospital in Lusaka, between January 1, 2008, and December 31, 2012. Data were extracted from electronic medical records. The main outcomes were maternal mortality, cesarean delivery, prenatal or intrapartum hemorrhage, stillbirth, a 5-minute Apgar score of less than 7, and admission to the neonatal intensive care unit.

RESULTS

A total of 62 470 deliveries were recorded. Rates of maternal mortality, cesarean delivery, and hemorrhage during pregnancy all declined over time. Decreased admissions to the neonatal intensive care unit were observed; however, the rate spiked temporarily in late 2011 and early 2012 before returning to previous levels. The proportion of stillbirths remained stable over time but reports of a 5-minute Apgar score of less than 7 rose.

CONCLUSION

Routinely collected obstetric and neonatal data could aid ongoing program monitoring and should be used to guide quality improvement activities.

Stillbirths and quality of care during labour at the low resource referral hospital of Zanzibar: a case-control study

BACKGROUND

To study determinants of stillbirths as indicators of quality of care during labour in an East African low resource referral hospital.

METHODS

A criterion-based unmatched unblinded case-control study of singleton stillbirths with birthweight ≥2000 g (n = 139), compared to controls with birthweight ≥2000 g and Apgar score ≥7 (n = 249).

RESULTS

The overall facility-based stillbirth rate was 59 per 1000 total births, of which 25 % was not reported in the hospital's registers. The majority of singletons had birthweight ≥2000 g (n = 139; 79 %), and foetal heart rate was present on admission in 72 (52 %) of these (intra-hospital stillbirths). Overall, poor quality of care during labour was the prevailing determinant of 71 (99 %) intra-hospital stillbirths, and median time from last foetal heart assessment till diagnosis of foetal death or delivery was 210 min. (interquartile range: 75-315 min.). Of intra-hospital stillbirths, 26 (36 %) received oxytocin augmentation (23 % among controls; odds ratio (OR) 1.86, 95 % confidential interval (CI) 1.06-3.27); 15 (58 %) on doubtful indication where either labour progress was normal or less dangerous interventions could have been effective, e.g. rupture of membranes. Substandard management of prolonged labour frequently led to unnecessary caesarean sections. The caesarean section rate among all stillbirths was 26 % (11 % among controls; OR 2.94, 95 % CI 1.68-5.14), and vacuum extraction was hardly ever done. Of women experiencing stillbirth, 27 (19 %) had severe hypertensive disorders (4 % among controls; OR 5.76, 95 % CI 2.70-12.31), but 18 (67 %) of these did not receive antihypertensives. An additional 33 (24 %) did not have blood pressure recorded during active labour. When compared to controls, stillbirths were characterized by longer admissions during labour. However, substandard care was prevalent in both cases and controls and caused potential risks for the entire population. Notably, women with foetal death on admission were in the biggest danger of neglect.

CONCLUSIONS

Intrapartum management of women experiencing stillbirth was a simple yet strong indicator of quality of care. Substandard care led to perinatal as well as maternal risks, which furthermore were related to unnecessary complex, time consuming, and costly interventions. Improvement of obstetric care is warranted to end preventable birth-related deaths and disabilities.

Stillbirths: The Hidden Birth Asphyxia - US and Global Perspectives

Stillbirths are among the most common pregnancy-related adverse outcomes but are more common in low-income and middle-income countries than in high-income countries. In high-income countries, most stillbirths occur early in the preterm period, whereas in low-income and middle-income countries, most occur in term or in late preterm births. In low-income and middle-income countries, conditions, such as prolonged or obstructed labor, placental abruption, preeclampsia/eclampsia, fetal growth restriction, fetal distress, breech and other abnormal presentations, and multiple births, are associated with stillbirth. In high-income countries, placental abnormalities are the most common associations. Globally, fetal asphyxia is likely the most common final pathway to stillbirth.

Inequalities in the coverage of place of delivery and skilled birth attendance: analyses of cross-sectional surveys in 80 low and middle-income countries

BACKGROUND

Having a health worker with midwifery skills present at delivery is one of the key interventions to reduce maternal and newborn mortality. We sought to estimate the frequencies of (a) skilled birth attendant coverage, (b) institutional delivery, and (c) the combination of place of delivery and type of attendant, in LMICs.

METHODS

National surveys (DHS and MICS) performed in 80 LMICs since 2005 were analyzed to estimate these four categories of delivery care. Results were stratified by wealth quintile based on asset indices, and by urban/rural residence. The combination of place of delivery and type of attendant were also calculated for seven world regions.

RESULTS

The proportion of institutional SBA deliveries was above 90 % in 25 of the 80 countries, and below 40 % in 11 countries. A strong positive correlation between SBA and institutional delivery coverage (rho: 0.97, p <0,001) was observed. Eight countries had over 10 % of home SBA deliveries, and two countries had over 10 % of institutional non-SBA deliveries. Except for South Asia, all regions had over 80 % of urban deliveries in the institutional SBA category, but in rural areas, only two regions (CEE & CIS, Middle East & North Africa) presented average coverage above 80 %. In all regions, institutional SBA deliveries were over 80 % in the richest quintile. Home SBA deliveries were more common in rural than in urban areas, and in the poorest quintiles in all regions. Facility non-SBA deliveries also tended to be more common in rural areas and among the poorest.

CONCLUSION

Four different categories of delivery assistance were identified worldwide. Pro-urban and pro-rich inequalities were observed for coverage of institutional SBA deliveries.

The global network antenatal corticosteroids trial: impact on stillbirth

Background

Antenatal corticosteroids are commonly used to reduce neonatal mortality, but most research to date has been in high-resource settings and few studies have evaluated its impact on stillbirth. In the Antenatal Corticosteroids Trial (ACT), a multi-country trial to assess impact of a multi-faceted intervention including antenatal corticosteroids to reduce neonatal mortality associated with preterm birth, we found an overall increase in 28-day neonatal mortality and stillbirth associated with the intervention.

Methods

The ACT was a cluster-randomized trial conducted in 102 clusters across 7 research sites in 6 countries (India [2 sites], Pakistan, Zambia, Kenya, Guatemala and Argentina), comparing an intervention to train birth attendants at all levels of the health system to identify women at risk of preterm birth, administer corticosteroids and refer women at risk. Because of inadequate gestational age dating, the <5^th percentile birth weight was used as a proxy for preterm birth. A pre-specified secondary outcome of the trial was stillbirth.

Results

After adjusting for the pre-trial imbalance in stillbirth rates, the ACT intervention was associated with a non-significant increased risk of stillbirth (aRR 1.08, 95 % CI, 0.99–1.17, p–0.073). Additionally, the stillbirth rate was higher in the term births (1.20 95 % CI 1.06–1.37, 0.004) and among those with signs of maceration (RR 1.18 (1.04–1.35), p = 0.013) in the intervention vs. control clusters. Differences in obstetric care favored the control clusters and maternal infection was likely more common in the intervention clusters.

Conclusions

In this pragmatic trial, limited data were available to identify the causes of the increase in stillbirths in the intervention clusters. A higher rate of stillbirth in the intervention clusters prior to the trial, differences in obstetric care and an increase in maternal infection are potential explanations for the observed increase in stillbirths in the intervention clusters during the trial.

Evaluation of maternal and perinatal outcomes among overweight women who experienced stillbirth

OBJECTIVE

To investigate associations between overweight and adverse clinical outcomes among women who experienced stillbirth.

METHODS

234 pregnant women (stillbirth group, n = 115; live birth group, n = 119) were included in this retrospective case-control study. Recorded risk factors were age, gravidity, parity, gestational weeks, fetal birth weight, gestational diabetes mellitus (GDM), preeclampsia (PE), intrauterine growth restriction (IUGR), levels of prenatal test markers (alpha-fetoprotein (AFP), pregnancy-associated plasma protein, human chorionic gonadotropin (β-hCG) and E3) and body mass index (BMI).

RESULTS

Statistically significant differences were observed between the groups in terms of birth weight, IUGR, GDM, PE, AFP level, β-hCG level, maternal E3 level and BMI (p < 0.05). Subgroup analyses revealed that 34 and 81 patients in the stillbirth group were of normal weight and overweight, respectively, fetal birth weight, IUGR, GDM, PE, AFP level, β-hCG level and E3 level differed significantly between these subgroups and the live birth group (p < 0.05).

CONCLUSIONS

Women who experience stillbirth tend to be more overweight than those who experience live birth. Additionally, IUGR, GDM and PE are more common among overweight women. Therefore, overweight women should be encouraged to lose weight before pregnancy. If they become pregnant without losing weight, they should be followed up closely to avoid adverse perinatal outcomes.

Mindfulness-based Intervention for Perinatal Grief Education and Reduction among Poor Women in Chhattisgarh, India: a Pilot Study

INTRODUCTION

Stillbirth is a significant public health problem in low-to-middle-income countries and results in perinatal grief, often with negative psychosocial impact. In low-resource settings, such as Chhattisgarh, India, where needs are high, it is imperative to utilize low-cost, effective interventions. Mindfulness-based stress reduction (MBSR) is an empirically sound intervention that has been utilized for a broad range of physical and mental health problems, and is adaptable to specific populations. The main objective of this pilot study was to explore the feasibility and effectiveness of a shortened, culturally adapted mindfulness-based intervention to address complex grief after stillbirth.

METHODS

We used an observational, pre-post-6-week post study design. The study instrument was made up of descriptive demographic questions and validated scales and was administered as a structured interview due to low literacy rates. We used a community participatory approach to culturally adapt the five-week mindfulness-based intervention and delivered it through two trained local nurses. Quantitative and qualitative data analyses explored study outcomes as well as acceptability and feasibility of the intervention.

RESULTS

29 women with a history of stillbirth enrolled, completed the pretest and began the intervention; 26 completed the five-week intervention and post-test (89.7%), and 23 completed the six-week follow-up assessment (88.5%). Pretest results included elevated psychological symptoms and high levels of perinatal grief, including the active grief, difficulty coping, and despair subscales. General linear modeling repeated measures was used to explore posttest and six-week follow up changes from baseline, controlling for significantly correlated demographic variables. These longitudinal results included significant reduction in psychological symptoms; four of the five facets of mindfulness changed in the desired direction, two significantly; as well as significant reduction in overall perinatal grief and on each of the three subscales.

DISCUSSION

The shortened, culturally adapted, mindfulness-based intervention pilot study was well received and had very low attrition. We also found significant reductions of perinatal grief and mental health symptoms over time, as well as a high degree of practice of mindfulness skills by participants. This study not only sheds light on the tremendous mental health needs among rural women of various castes who have experienced stillbirth in Chhattisgarh, it also points to a promising effective intervention with potential to be taken to scale for wider delivery.

Frequency of Stillbirths in a Tertiary Care Hospital, Karachi

Background and Objective:

Pakistan accounts for the highest stillbirth rate in the world. Therefore, this observational study was planned to determine the prevalence of stillbirths and its associated demographic characteristics in the given context. Hence our objective included: To determine the frequency of stillbirths with reference to parity and gestational age in a tertiary care public hospital, Karachi. To determine the socio-demographic characteristics of families with stillbirths.

Methods:

All pregnant mothers who delivered stillbirth babies at Gynaecology and Obstetrics ward of Jinnah Postgraduate Medical Center, Karachi a tertiary care facility were prospectively enrolled from October 2012 to September 2013. Deliveries occurred before 28 weeks of gestational age were excluded. Gestational age was confirmed from hospital record and attending physicians. Data was collected on predesigned proforma and analyzed using descriptive statistics.

Results:

Among 7708 registered deliveries, 137 were stillbirths. A total of 84 mothers were primiparous and 12% of mothers were below 20 years at the time of delivery. Majority of stillbirths were macerated type (80.3%) and 20% were fresh stillbirth. About 55% of still births occurred between 33-37 weeks and 20% between 28-32 weeks. Almost 80% (109) of stillbirths were low birth weight and only 20% (28) were normal birth weight.

Conclusion:

This study shows that stillbirths are more common in primiparous mothers in a given context. Conducting awareness sessions with special focus on antenatal and obstetrical care of primiparous may be helpful to reduce still births.

Criteria-based audit of caesarean section in a referral hospital in rural Tanzania

OBJECTIVE

WHO uses the Caesarean section (CS) rate to monitor implementation of emergency obstetric care (EmOC). Although CS rates are rising in sub-Saharan Africa, maternal outcome has not improved. We audited indications for CS and related complications among women with severe maternal morbidity and mortality in a referral hospital in rural Tanzania.

METHODS

Cross-sectional study was from November 2009 to November 2011. Women with severe maternal morbidity and mortality were identified and those with CS were included in this audit. Audit criteria were developed based on the literature review and (inter)national guidelines. Tanzanian and Dutch doctors reviewed hospital notes. The main outcome measured was prevalence of substandard quality of care leading to unnecessary CS and delay in performing interventions to prevent CS.

RESULTS

A total of 216 maternal near misses and 32 pregnancy-related deaths were identified, of which 82 (33.1%) had a CS. Indication for CS was in accordance with audit criteria for 36 of 82 (44.0%) cases without delay. In 20 of 82 (24.4%) cases, the indication was correct; however, there was significant delay in providing standard obstetric care. In 16 of 82 (19.5%) cases, the indication for CS was not in accordance with audit criteria. During office hours, CS was more often correctly indicated than outside office hours (60.0% vs. 36.0%, P < 0.05).

DISCUSSION

Caesarean section rate is not an useful indicator to monitor quality of EmOC as a high rate of unnecessary and potentially preventable CS was identified in this audit.

The Global Network Maternal Newborn Health Registry: a multi-national, community-based registry of pregnancy outcomes

BACKGROUND

The Global Network for Women's and Children's Health Research (Global Network) supports and conducts clinical trials in resource-limited countries by pairing foreign and U.S. investigators, with the goal of evaluating low-cost, sustainable interventions to improve the health of women and children. Accurate reporting of births, stillbirths, neonatal deaths, maternal mortality, and measures of obstetric and neonatal care is critical to efforts to discover strategies for improving pregnancy outcomes in resource-limited settings. Because most of the sites in the Global Network have weak registration within their health care systems, the Global Network developed the Maternal Newborn Health Registry (MNHR), a prospective, population-based registry of pregnancies at the Global Network sites to provide precise data on health outcomes and measures of care.

METHODS

Pregnant women are enrolled in the MNHR if they reside in or receive healthcare in designated groups of communities within sites in the Global Network. For each woman, demographic, health characteristics and major outcomes of pregnancy are recorded. Data are recorded at enrollment, the time of delivery and at 42 days postpartum.

RESULTS

From 2010 through 2013 Global Network sites were located in Argentina, Guatemala, Belgaum and Nagpur, India, Pakistan, Kenya, and Zambia. During this period, 283,496 pregnant women were enrolled in the MNHR; this number represented 98.8% of all eligible women. Delivery data were collected for 98.8% of women and 42-day follow-up data for 98.4% of those enrolled. In this supplement, there are a series of manuscripts that use data gathered through the MNHR to report outcomes of these pregnancies.

CONCLUSIONS

Developing public policy and improving public health in countries with poor perinatal outcomes is, in part, dependent upon understanding the outcome of every pregnancy. Because the worst pregnancy outcomes typically occur in countries with limited health registration systems and vital records, alternative registration systems may prove to be highly valuable in providing data. The MNHR, an international, multicenter, population-based registry, assesses pregnancy outcomes over time in support of efforts to develop improved perinatal healthcare in resource-limited areas.

Risk factors for maternal death and trends in maternal mortality in low- and middle-income countries: a prospective longitudinal cohort analysis

Background

Because large, prospective, population-based data sets describing maternal outcomes are typically not available in low- and middle-income countries, it is difficult to monitor maternal mortality rates over time and to identify factors associated with maternal mortality. Early identification of risk factors is essential to develop comprehensive intervention strategies preventing pregnancy-related complications. Our objective was to describe maternal mortality rates in a large, multi-country dataset and to determine maternal, pregnancy-related, delivery and postpartum characteristics that are associated with maternal mortality.

Methods

We collected data describing all pregnancies from 2010 to 2013 among women enrolled in the multi-national Global Network for Women’s and Children’s Health Research Maternal and Neonatal Health Registry (MNHR). We reported the proportion of mothers who died per pregnancy and the maternal mortality ratio (MMR). Generalized linear models were used to evaluate the relationship of potential medical and social factors and maternal mortality and to develop point and interval estimates of relative risk associated with these factors. Generalized estimating equations were used to account for the correlation of outcomes within cluster to develop appropriate confidence intervals.

Results

We recorded 277,736 pregnancies and 402 maternal deaths for an MMR of 153/100,000 live births. We observed an improvement in the total MMR from 166 in 2010 to 126 in 2013. The MMR in Latin American sites (91) was lower than the MMR in Asian (178) and African sites (125). When adjusted for study site and the other variables, no formal education (RR 3.2 [1.5, 6.9]), primary education only (RR 3.4 [1.6, 7.5]), secondary education only (RR 2.5 [1.1, 5.7]), lack of antenatal care (RR 1.8 [1.2, 2.5]), caesarean section delivery (RR 1.9 [1.3, 2.8]), hemorrhage (RR 3.3 [2.2, 5.1]), and hypertensive disorders (RR 7.4 [5.2, 10.4]) were associated with higher risks of death.

Conclusions

The MNHR identified preventable causes of maternal mortality in diverse settings in low- and middle-income countries. The MNHR can be used to monitor public health strategies and determine their association with reducing maternal mortality.

Establishment of a Maternal Newborn Health Registry in the Belgaum District of Karnataka, India

Background

Pregnancy-related vital registration is important to inform policy to reduce maternal, fetal and newborn mortality, yet few systems for capturing accurate data are available in low-middle income countries where the majority of the mortality occurs. Furthermore, methods to effectively implement high-quality registration systems have not been described. The goal of creating the registry described in this paper was to inform public health policy makers about pregnancy outcomes in our district so that appropriate interventions to improve these outcomes could be undertaken and to position the district to be a leader in pregnancy-related public health research.

Methods

We created a prospective maternal and newborn health registry in Belgaum, Karnataka State, India. To initiate this registry, we worked with the Ministry of Health to first establish estimated birth rates and define the catchment areas of the clusters, working within the existing health system and primary health centers. We also undertook household surveys to identify women likely to become pregnant. We then implemented monitoring measures to ensure high quality and completeness of the maternal newborn health registry. All pregnant women in the catchment area were identified, consented and enrolled during pregnancy, with follow-up visits to ascertain pregnancy outcomes and mother/infant status at 42-days postpartum.

Results

From 2008 through 2014, we demonstrated continued improvements in both the coverage for enrollment and accuracy of reporting pregnancy outcomes within the defined catchment area in Belgaum, India. Nearly 100% of women enrolled had follow-up at birth and 99% had 42-day follow-up. Furthermore, we facilitated earlier enrollment of women during pregnancy while achieving more timely follow-up and decreased time of reporting from the date of the pregnancy event.

Conclusions

We created a pregnancy-related registry which includes demographic data, risk factors, and outcomes allowing for high rates of ascertainment and follow-up while working within the existing health system. Understanding the elements of the system used to create the registry is important to improve the quality of the results. Tracking of pregnancies and their outcomes is an important step toward reducing maternal and perinatal mortality.

Research results from a registry supporting efforts to improve maternal and child health in low and middle income countries

The National Institute of Child Health and Human Development created and continues to support the Global Network for Women's and Children's Health Research, a partnership between research institutions in the US and low-middle income countries. This commentary describes a series of 15 papers emanating from the Global Network's Maternal and Newborn Health Registry. Using data from 2010 to 2013, the series of papers describe nearly 300,000 pregnancies in 7 sites in 6 countries - India (2 sites), Pakistan, Kenya, Zambia, Guatemala and Argentina. These papers cover a wide range of topics including several dealing with efforts made to ensure data quality, and others reporting on specific pregnancy outcomes including maternal mortality, stillbirth and neonatal mortality. Topics ranging from antenatal care, adolescent pregnancy, obstructed labor, factors associated with early initiation of breast feeding and maintenance of exclusive breast feeding and contraceptive usage are presented. In addition, case studies evaluating changes in mortality over time in 3 countries - India, Pakistan and Guatemala - are presented. In order to make progress in improving pregnancy outcomes in low-income countries, data of this quality are needed.
