Perinatal outcomes after hypertensive disorders in pregnancy in a low resource setting

Co-creation of a toolkit to assist risk communication and clinical decision-making in severe preeclampsia: SPOT-Impact study design

Globally, the incidence of hypertensive disorders of pregnancy, especially preeclampsia, remains high, particularly in low- and middle-income countries. The burden of adverse maternal and perinatal outcomes is particularly high for women who develop a hypertensive disorder remote from term (<34 weeks). In parallel, many women have a suboptimal experience of care. To improve the quality of care in terms of provision and experience, there is a need to support the communication of risks and making of treatment decision in ways that promote respectful maternity care. Our study objective is to co-create a tool(kit) to support clinical decision-making, communication of risks and shared decision-making in preeclampsia with relevant stakeholders, incorporating respectful maternity care, justice, and equity principles. This qualitative study detailing the exploratory phase of co-creation takes place over 17 months (Nov 2021-March 2024) in the Greater Accra and Eastern Regions of Ghana. Informed by ethnographic observations of care interactions, in-depth interviews and focus group and group discussions, the tool(kit) will be developed with survivors and women with hypertensive disorders of pregnancy and their families, health professionals, policy makers, and researchers. The tool(kit) will consist of three components: quantitative predicted risk (based on external validated risk models or absolute risk of adverse outcomes), risk communication, and shared decision-making support. We expect to co-create a user-friendly tool(kit) to improve the quality of care for women with preeclampsia remote from term which will contribute to better maternal and perinatal health outcomes as well as better maternity care experience for women in Ghana.

Factors related to blood pressure assessment during pregnancy in Ethiopia: Multilevel analysis using the 2019 mini demographic and health survey data

INTRODUCTION

Blood pressure assessment is an essential strategy for early detection and treatment of hypertension and hypotension. Hypertensive disorders of pregnancy (HDP) are major public health problems resulting in a significant burden of perinatal and maternal morbidity and mortality. In Ethiopia, among pregnancies complicated by HDP, 25% end up with perinatal death. Perinatal and maternal mortality related to HDP were found to be higher in Ethiopia compared to high-income and most of the low- and middle-income countries. Despite its importance, there is limited evidence on blood pressure assessment during pregnancy. Therefore, this study aimed to determine the prevalence of blood pressure assessment during pregnancy and its associated factors in Ethiopia.

METHODS

This study was based on the 2019 Mini Ethiopian Demographic and Health Survey data. A total weighted sample of 2923 women who had a live birth five years before the survey were included and Stata version 16 software was used for statistical analysis. To identify associated factors, a multilevel robust Poisson regression model was fitted since the prevalence of blood pressure assessment was higher than 10%. Variables with p-value < 0.2 in the bi-variable analysis were exported to the multivariable analysis. In the multivariable analysis, the adjusted prevalence ratio with its 95% confidence interval was used to declare a statistically significant association.

RESULTS

In Ethiopia, the prevalence of blood pressure assessment during pregnancy was 88.1% (95% CI: 86.9%, 89.2%). In the multivariable multilevel robust Poisson analysis, primary education and secondary education, grand-multiparity, initiation of antenatal care before three months and 3-6 months, four and above antenatal care visits, being counselled by a health professional, being from richer and richest households, residing in Afar and Amhara regions were significantly associated with BP assessment during pregnancy in Ethiopia.

CONCLUSION AND RECOMMENDATIONS

To reduce the high burden of mortality related to hypertensive disorders of pregnancy in the country, blood pressure assessment should be improved. Therefore, policymakers should design interventions that empower women in terms of education and economy, promoting early initiation of antenatal care visits and prenatal counselling could improve blood pressure assessment.

Analysis of the impact of maternal sepsis on pregnancy outcomes: a population-based retrospective study

BACKGROUND

To investigate the association between maternal sepsis during pregnancy and poor pregnancy outcome and to identify risk factors for poor birth outcomes and adverse perinatal events.

METHODS

We linked the Taiwan Birth Cohort Study (TBCS) database and the Taiwanese National Health Insurance Database (NHID) to conduct this population-based study. We analysed the data of pregnant women who met the criteria for sepsis-3 during pregnancy between 2005 and 2017 as the maternal sepsis cases and selected pregnant women without infection as the non-sepsis comparison cohort. Sepsis during pregnancy and fulfilled the sepsis-3 definition proposed in 2016. The primary outcome included low birth weight (LBW, < 2500 g) and preterm birth (< 34 weeks), and the secondary outcome was the occurrence of adverse perinatal events.

RESULTS

We enrolled 2,732 women who met the criteria for sepsis-3 during pregnancy and 196,333 non-sepsis controls. We found that the development of maternal sepsis was highly associated with unfavourable pregnancy outcomes, including LBW (adjOR 9.51, 95% CI 8.73-10.36), preterm birth < 34 weeks (adjOR 11.69, 95%CI 10.64-12.84), and the adverse perinatal events (adjOR 3.09, 95% CI 2.83-3.36). We also identified that socio-economically disadvantaged status was slightly associated with an increased risk for low birth weight and preterm birth.

CONCLUSION

We found that the development of maternal sepsis was highly associated with LBW, preterm birth and adverse perinatal events. Our findings highlight the prolonged impact of maternal sepsis on pregnancy outcomes and indicate the need for vigilance among pregnant women with sepsis.

Serum Uric Acid Levels as a Risk Stratification Tool in Hypertensive Disorders of Pregnancy: A Retrospective Study

BACKGROUND

Worldwide, hypertensive disorders of pregnancy (HDP) are among the leading causes of maternal and fetal morbidity and mortality. Serum uric acid is a test that can evaluate the severity of HDP and the associated maternal and fetal morbidity and mortality.

AIM

To examine the relationship between maternal serum uric acid levels and the severity of HDP and overall pregnancy outcomes.

MATERIAL AND METHODS

A retrospective study was conducted on women with a gestational age > 20 weeks and BP >140/90 mmHg over three years. A total of 134 patients were included in the study. Patients with chronic hypertension, hyperuricemia without hypertension, and other major illnesses were excluded. Data were collected from medical records, including age, gravida, parity, weight, height, gestational age, blood pressure at admission, urine albumin, and serum uric acid levels.

RESULTS

Of the 134 enrolled women with HDP, 76 had gestational hypertension, 41 had preeclampsia, and 17 had eclampsia. Mean uric acid levels in mg/dL were 6.06±1.651, 6.20±0.824, and 7.38±1.26 in gestational hypertension, preeclampsia, and eclampsia, respectively, which was a significant association (p=0.002). Mean uric acid in mg/dL was 5.86±1.27 in intensive care unit (ICU) patients compared to 6.45±1.39 in ward patients (p=0.015). There was a significantly increased risk of ICU admission and preterm delivery (r=-0.401, p<0.001) in patients with elevated uric acid levels. There was a significantly increased risk of low-birth-weight babies with elevated uric acid levels (r=-0.278, p=0.001). However, there was no statistically significant increased risk of newborn intensive care unit admissions (p=0.264) with elevated uric acid levels.

CONCLUSION

Serum uric acid levels vary significantly in HDP and were found to be elevated in severe preeclampsia and eclampsia. It can be considered for risk stratification in HDP based on disease severity; however, its role in determining outcomes is debatable. Using serum uric acid levels in predictive models along with known biomarkers may determine its possible additional value in disease prediction and severity.

Pregnancy outcomes in women with gestational hypertension and preeclampsia at Paropakar Maternity and Women's Hospital, Nepal: A retrospective study

INTRODUCTION

Gestational hypertension and preeclampsia are the most common types of hypertensive disorder in pregnancy and these conditions are associated with adverse maternal and fetal outcomes. This study aims to determine the differences in pregnancy outcomes in women with gestational hypertension and preeclampsia.

METHODS

A retrospective study was done at The Paropakar Maternity and Women's Hospital, a tertiary level hospital, in the Kathmandu, Nepal. Pregnant women who had given birth at the hospital between September 17 and December 18 of 2017 were included. Data were obtained from the non-digitalized hospital records. The adjusted odds ratio (AOR) and 95% confidence interval were computed using logistic regression analysis. Multivariable analysis of pregnancy outcomes (cesarean sections, low birth weight, and preterm birth) was adjusted for maternal age, parity, twin birth, gestational age, calcium supplementation, and maternal co-morbidity.

RESULTS

Preeclampsia was strongly associated with cesarean section compared to normal pregnancies (OR = 8.11, p<0.001). Whereas the odds of cesarean section among women with gestational hypertension was almost 2 times (OR = 1.89, p<0.001). Preterm birth was not significantly associated with gestational hypertension but was associated with preeclampsia (OR = 3.39, p<0.001). Gestational hypertension and preeclampsia were not associated with low birth weight.

CONCLUSION

In Nepal, women who develop preeclampsia seem at higher risk of having adverse pregnancy outcomes than women with gestational hypertension. These findings should be considered by national health authorities and other health organizations when setting new priorities to improve pregnancy outcomes.

Causes, survival rates, and short-term outcomes of preterm births in a tertiary hospital in a low resource setting: An observational cohort study

Background

Prematurity is the most important cause of death among children under the age of five years. Globally, most preterm births occur in Sub-Saharan Africa. Subsequent prematurity leads to significant neonatal morbidity, mortality and long-term disabilities. This study aimed to determine the causes, survival rates and outcomes of preterm births up to six weeks of corrected age in Ghana.

Materials and methods

An observational prospective cohort study of infants born preterm was conducted in a tertiary hospital in Accra, Ghana from August 2019 to March 2020. Inclusion was performed within 48 h after birth of surviving infants; multiple pregnancies and stillbirths were excluded. Causes of preterm birth were categorized as spontaneous (including preterm pre-labour rupture of membranes) or provider-initiated (medically indicated birth based on maternal or fetal indications). Survival rates and adverse outcomes were assessed at six weeks of corrected age. Recruitment and follow-up were suspended due to the COVID-19 outbreak. Descriptive statistics and differences between determinants were calculated using Chi-squared tests or Kruskal-Wallis test.

Results

Of the 758 preterm deliveries, 654 (86.3%) infants were born alive. 179 were enrolled in the cohort and were analyzed. Nine (5%) were extremely preterm [gestational age (GA) < 28 weeks], 40 (22%) very preterm (GA 28-31 weeks), and 130 (73%) moderate to late preterm (GA 32-37 weeks) births. Most deliveries (n = 116, 65%) were provider-initiated, often due to hypertensive disorders in pregnancy (n = 79, 44.1%). Sixty-two infants were followed-up out of which fifty-two survived, presenting a survival rate of 84% (n = 52/62) at six weeks corrected age in this group. Most infants (90%, n = 47/52) experienced complications, predominantly consisted of NICU admission (92%) and interval illnesses (21%) including jaundice and sepsis.

Conclusions

The incidence of adverse outcomes associated with preterm birth in a tertiary facility with NICU capacity is high. Larger longitudinal studies are needed for an in-depth understanding of the causes and longer-term outcomes of preterm birth, and to identify effective strategies to improve outcomes in resource constrained settings.

Modeling clinical and non-clinical determinants of intrapartum stillbirths in singletons in six public hospitals in the Greater Accra Region of Ghana: a case-control study

The Greater Accra Region (GAR) of Ghana records 2000 stillbirths annually and 40% of them occur intrapartum. An understanding of the contributing factors will facilitate the development of preventive strategies to reduce the huge numbers of intrapartum stillbirths. This study identified determinants of intrapartum stillbirths in GAR. A retrospective 1:2 unmatched case-control study was conducted in six public hospitals in the Greater Accra Region of Ghana. A multivariable binary logistic regression model was used to quantify the effect of exposures on intrapartum stillbirth. The area under the receiver operating characteristics curve and the Brier scores were used to screen potential risk factors and assess the predictive performance of the regression models. The following maternal factors increased the odds of intrapartum stillbirths: pregnancy-induced hypertension (PIH) [adjusted Odds Ratio; aOR = 3.72, 95% CI:1.71-8.10, p < 0.001]; antepartum haemorrhage (APH) [aOR = 3.28, 95% CI: 1.33-8.10, p < 0.05] and premature rupture of membranes (PROM) [aOR = 3.36, 95% CI: 1.20-9.40, p < 0.05]. Improved management of PIH, APH, PROM, and preterm delivery will reduce intrapartum stillbirth. Hospitals should improve on the quality of monitoring women during labor. Auditing of intrapartum stillbirths should be mandatory for all hospitals and Ghana Health Service should include fetal autopsy in stillbirth auditing to identify other causes of fetal deaths. Interventions to reduce intrapartum stillbirth must combine maternal, fetal and service delivery factors to make them effective.

Effect of hypertensive disorders of pregnancy on pubertal development in daughters and sons: a systematic review and meta-analysis

Hypertensive disorders of pregnancy (HDP) are a major cause of maternal and offspring morbidity and mortality worldwide. Several studies in recent years have focused on the link between HDP and pubertal development in offspring. The goal of this study was to synthesize the published literature on the effect of HDP on pubertal development in offspring by a systematic review and meta-analysis (PROSPERO 2021: CRD42020148736). A systematic literature search of several databases was conducted through December 2021, focusing on studies reporting pubertal development in offspring of women with and without HDP exposure. Primary outcomes of interest included offspring body mass index (BMI), height, waist and hip circumference, fat mass, pubarche, thelarche, and age at menarche. A total of 21 studies were finally included. Significantly higher values of BMI (SMD: 0.16 [0.11, 0.22]; p < 0.01) and waist circumference (SMD: 0.21 [0.14, 0.29]; p < 0.01) were found in offspring exposed to maternal HDP. In addition, a tendency of the early development of secondary sexual characteristics only in daughters was presented in offspring whose mothers were diagnosed with HDP. The findings imply a possible effect of HDP on pubertal development in offspring, especially for their BMI and waist circumference, which highlights the importance of focusing on adolescent developmental abnormalities in offspring exposed to HDP.

Incidence of adverse perinatal outcomes and risk factors among women with pre-eclampsia, southern Ethiopia: a prospective open cohort study

BACKGROUND

In Ethiopia, in 2021, more than 80% of all newborn deaths were caused by preventable and treatable conditions. This study aimed to measure the incidence of adverse perinatal outcomes and risk factors among women with pre-eclampsia in the Sidama region of southern Ethiopia.

METHODS

A prospective open cohort study was conducted from 8 August 2019 to 1 October 2020. We enrolled 363 women with pre-eclampsia and 367 normotensive women at ≥20 weeks of gestation and followed them until the 37th week. We then followed them until the seventh day after delivery up to the last perinatal outcome status was ascertained. A log-binomial logistic regression model was used to estimate the incidence of adverse perinatal outcomes and its risk factors among women with pre-eclampsia. Relative risk (RR) with a 95% CI was reported. A p<0.05 was considered statistically significant.

RESULTS

There were 224 adverse perinatal outcomes observed in the 363 women with pre-eclampsia compared with 136 adverse perinatal outcomes in the 367 normotensive women (p<0.001). There were 23 early neonatal deaths in the pre-eclampsia group compared with six deaths in the normotensive group (p<0.001). There were 35 perinatal deaths in the pre-eclampsia group compared with 16 deaths in the normotensive group (p<0.05). Women with severe features of pre-eclampsia had a 46% (adjusted RR 1.46, 95% CI 1.38 to 2.77) higher risk for adverse perinatal outcomes compared with women without severe features of pre-eclampsia.

CONCLUSIONS

In this study, more adverse perinatal outcomes occurred among women with pre-eclampsia after controlling for confounders. A higher perinatal outcome observed among women with pre-eclampsia, especially among women with severe features of pre-eclampsia, and those admitted to hospital at <34 weeks. This paper highlights the significantly elevated perinatal risks associated with pre-eclampsia, especially when it has severe features.

A novel 12-hour versus 24-hour magnesium sulfate regimen in the management of eclampsia and preeclampsia in Ghana (MOPEP Study): A randomized controlled trial

OBJECTIVE

We compared the efficacy of a 12-h versus 24-h regimen of intramuscular magnesium sulfate in the management of eclampsia and preeclampsia.

METHODS

This is an open-labeled parallel randomized controlled trial conducted in Accra, Ghana from November 2018 to November 2020. Participants were adult pregnant women admitted to the Korle Bu Teaching Hospital (KBTH) with a diagnosis of antepartum, intrapartum, or postpartum eclampsia or preeclampsia with severe features, having received no more than a loading dose of magnesium sulfate prior to admission at KBTH. Participants in the standard 24-h group received a loading dose of magnesium sulfate 4 g intravenous and 10 g intramuscular (5 g in each buttock) followed by six, 5 g intramuscular maintenance doses over 24 h. Participants in the 12-h intervention group received the same loading dose followed by three, 5 g intramuscular maintenance doses over 12 h. The primary outcome was occurrence of seizure after completion of the assigned magnesium sulfate regimen. Secondary outcomes were magnesium sulfate toxicity, magnesium sulfate side effects, maternal outcomes (mode of delivery, duration of inpatient admission, duration of urethral catheterization), maternal complications (pulmonary edema, acute kidney injury, intensive care unit admission, death), and neonatal outcomes.

RESULTS

Among 1176 total participants, we found no difference in occurrence of seizure after completion of the assigned regimen in the 24-h group (n = 5, 0.9%) versus the 12-h group (n = 2, 0.3%), P = 0.29; RR 0.40, 95% CI 0.08, 2.04), or in occurrence of seizure any time after enrollment (n = 9, 1.5% vs. n = 5, 0.9%, P = 0.28, RR 0.55, 95% CI 0.19-1.64). Participants in the 12-h group had a shorter duration of inpatient admission (9.4 ± 8.8 vs. 7.7 ± 6.5 days, P = 0.0009) and urethral catheterization (2.1 ± 1.0 vs. 1.9 ± 1.3 days, P < 0.0001). Rates of side effects from magnesium sulfate were lower in the 12-h group: pain at the injection site (94.8% (n = 548) vs. 91.5% (n = 540), P = 0.03), inflammation (62.2% (n = 358) vs. 40.0% (n = 237), P < 0.0001), and bleeding or bruising at the injection site (25.1% (n = 144) vs. 14.4% (n = 85), P < 0.0001).

CONCLUSIONS

Compared with 24 h, 12 h of intramuscular magnesium sulfate showed similar rates of seizures, with fewer side effects and shorter inpatient admission.

Anti-hypertensive use for non-severe gestational hypertension in Botswana: A case-control study

OBJECTIVE

The fetal risks and benefits of antihypertensives to treat gestational hypertension in pregnancy are understudied, particularly in low- and middle-income countries.

METHODS

We performed a nested case-control study within a retrospective cohort of obstetrical patients in Botswana from 2014 to 2019. We included women carrying singletons who developed new onset non-severe hypertension (140-159 mm Hg systolic or 90-109 mm Hg diastolic blood pressure) after 20 weeks of pregnancy. Cases were defined as women with either small-for-gestational-age (SGA) infants or stillbirth, analyzed separately; controls were otherwise similar women without the adverse outcome in each analysis.

RESULTS

We identified 1932 cases of SGA (7925 controls) and 316 cases of stillbirth (9619 controls). Cases with SGA were more likely to have used an anti-hypertensive than controls (33% vs 29%, adjusted odds ratio [aOR] 1.28, 95% confidence interval [CI] 1.15-1.43). Cases with stillbirth were more likely to have used an anti-hypertensive than controls (42% versus 29%, aOR 1.45, 95% CI 1.14-1.83).

CONCLUSION

Anti-hypertensive use for new-onset gestational hypertension was associated with an increased risk of having an SGA infant or a stillbirth among women who never developed severe hypertension. These data support conduct of a randomized clinical trial to determine the appropriate use of anti-hypertensives in non-severe gestational hypertension.

The burden of severe hypertensive disorders of pregnancy on perinatal outcomes: a nationwide case-control study in Suriname

BACKGROUND

Latin America and the Caribbean is the region with the highest prevalence of hypertensive disorders of pregnancy worldwide. In Suriname, where the stillbirth rate is the second highest in the region, it is not yet known which maternal factors contribute most substantially.

OBJECTIVE

The aims of this study in Suriname were to (1) study the impact of different types of maternal morbidity on adverse perinatal outcomes and (2) study perinatal birth outcomes among women with severe hypertensive disorders of pregnancy.

STUDY DESIGN

A case-control study was conducted between March 2017 and February 2018 during which time all hospital births (86% of total) in Suriname were included. We identified babies with adverse perinatal outcomes (perinatal death or neonatal near miss) and women with severe maternal morbidity (according to the World Health Organization Near Miss tool). Stillbirths and early neonatal deaths (<7 days) were considered perinatal death. We defined a neonatal near miss as a birthweight below 1750 g, gestational age <33 weeks, 5-minute Apgar score <7, and preterm intrauterine growth restriction <p3. Descriptive statistics and multivariate binary logistic regression analyses were conducted.

RESULTS

In the 1-year study period, adverse perinatal outcomes were reported for 638 singleton births of which 120 (18.8%) involved women with severe maternal morbidity. In most of these cases, the mother suffered severe hypertensive disorders of pregnancy (n=95/120, 79.2%). Severe hypertensive disorders of pregnancy were strongly associated with adverse perinatal outcomes (adjusted odds ratio, 11.1; 95% confidence interval, 8.3–14.9). The prevalence of severe hypertensive disorders of pregnancy in Suriname was 2.5% (234/9197). Of the 215 singleton pregnancies complicated by severe hypertensive disorders, adverse perinatal outcomes were reported for 44.2% of them (n=95/215; adjusted odds ratio, 11.1; 95% confidence interval, 8.3–14.9); perinatal death accounted for 18.1% of these cases (n=39/215; adjusted odds ratio, 8.6; 95% confidence interval, 5.8–12.7) and neonatal near miss accounted for another 26.0% (n=56/215). Women with severe hypertensive disorders of pregnancy had a preterm birth (<37 weeks) in 67.1% of the cases (n=143/215; adjusted odds ratio, 14.1; 95% confidence interval, 10.5–19.0), a baby with a low birthweight (<2500 g) in 62.2% of the cases (n=130/215; adjusted odds ratio, 10.8; 95% confidence interval, 8.1–14.5), and a baby with a low 5-minute Apgar score in 20.5% of the cases (n=43/215; adjusted odds ratio, 6.9; 95% confidence interval, 4.8–10.0).

CONCLUSION

In Suriname, severe hypertensive disorders of pregnancy are strongly associated with adverse perinatal outcomes, with an increased risk for preterm birth, low birthweight, low Apgar score, and perinatal mortality. Prevention, early diagnosis, and management of hypertensive disorders of pregnancy are expected to reduce perinatal deaths substantially. Recommendations to reduce perinatal deaths in Suriname include the establishment of a national health plan for the management of severe hypertensive disorders of pregnancy and the introduction of perinatal death and neonatal near miss reviews.

Determinants of Pregnancy-Induced Hypertension among Mothers Attending Public Hospitals in Wolaita Zone, South Ethiopia: Findings from Unmatched Case-Control Study

BACKGROUND

It has been estimated that approximately 14% of maternal death has resulted due to pregnancy-induced hypertension. Evidence also suggests that pregnancy-induced hypertension may result in adverse maternal and child outcomes. The aim of this study was to assess the determinants of pregnancy-induced hypertension among mothers attending antenatal and delivery services at public health hospitals in Wolaita zone, southern Ethiopia.

METHODS

An institutionally based unmatched case-control study was conducted at three public hospitals. A total of 283 study participants were recruited for this study. Cases were selected consecutively as they were being diagnosed for pregnancy-induced hypertension, and two controls were selected for each case. Data were collected via the face-to-face interview technique using a pretested questionnaire. Unconditional logistic regression analysis was used to identify the independent predictor variables and produced odds ratio (OR) as a measure of association.

RESULTS

The mean ± (SD) ages of cases and controls were 26.1 ± 5.4 and 26.1 ± 4.5 years, respectively. Being rural residents (AOR: 2.25, 95% CI: 1.09-4.65), illiterate (AOR: 3.12, 95% CI: 1.20-8.08), having the history of pregnancy-induced hypertension (AOR: 6.62, 95% CI: 2.48-17.71), history of kidney disease (AOR: 3.14, 95% CI: 1.05-9.38), and family history of hypertension (AOR: 5.59, 95% CI: 2.73-11.45) were determinants that increased the odds of suffering from hypertensive disorders of pregnancy. More importantly, eating vegetables and fruit reduces the odds of suffering from pregnancy-induced hypertension by 77% (AOR: 0.23, 95% CI: 0.06-0.79).

CONCLUSION

Being rural residents, illiterate, having a history of pregnancy-induced hypertension, and history of kidney disease, as well as the family history of hypertension were identified determinates of hypertensive disorders of pregnancy in the study area. Furthermore, fruit and vegetable intakes were identified as protective factors for pregnancy-induced hypertension. Therefore, early diagnosis and intervention of this disorder are warranted to reduce adverse outcomes.

Neurodevelopmental assessment of infants born to mothers with hypertensive disorder of pregnancy at six months of age

Infant neurodevelopment is a complex process which may be affected by different events during pregnancy, such as hypertensive disorders of pregnancy (HDP). We conducted a prospective cohort study to compare the prevalence of neurodevelopmental disorders in infants born to mothers with and without HDP at six months of age. Participants attended the Health Observatory of Instituto de Desarrollo e Investigaciones Pediátricas "Prof. Dr. Fernando E. Viteri" during 2018 and 2019. Infant neurodevelopment was assessed with the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III). Data were analyzed using Chi-square, Student's t-test and Mann-Whitney test. Of the 132 participating infants, 68 and 64 were born to mothers with and without HDP, respectively. At six months, the prevalence of risk of neurodevelopmental delay was significantly higher in infants born to mothers with than without HDP (27.9% vs. 9.4%; p = 0.008) (odds ratio, 3.71; 95% confidence interval, 1.30; 12.28). In conclusion, infants born to mothers with HDP had three times increased risk of neurodevelopmental delay at six months of age.

Health of 2-year-old children born after vitrified oocyte donation in comparison with peers born after fresh oocyte donation

STUDY QUESTION

Does oocyte vitrification adversely affect the health of 2-year-old children compared with peers born after use of fresh oocytes in a donation programme?

SUMMARY ANSWER

The growth and health of 2-year-old children born after oocyte vitrification are similar to those of peers born after use of fresh oocytes.

WHAT IS KNOWN ALREADY

Although oocyte vitrification is a well-established procedure in ART, the evidence on its safety for offspring is limited. Currently, no disadvantageous effects of oocyte vitrification have been shown in terms of obstetric and neonatal outcome. However, no data beyond the neonatal period are available to date.

STUDY DESIGN, SIZE, DURATION

A combined retrospective and prospective observational study was performed in a tertiary reproductive centre. The retrospective data were available in our extensive database of children born after ART. Donor cycles with an oocyte retrieval between January 2010 and March 2017 and a fresh embryo transfer resulting in the livebirth of a singleton were selected from the established oocyte donation programme. Fresh or vitrified oocytes were used in the donor cycles and all pregnancies in oocyte recipients were achieved after ICSI. Only children residing in Belgium were eligible for follow-up.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Biometric and health parameters of 72 children born after oocyte vitrification were compared with those of 41 children born after use of a fresh oocyte. Data were collected by means of questionnaires and physical examinations at the age of 21–30 months. The primary outcome measures were anthropometry and health at 2 years of age.

MAIN RESULTS AND THE ROLE OF CHANCE

Length, weight, BMI, head circumference, left arm circumference and waist circumference at the age of 2 years were comparable between the vitrification and fresh group, also after adjustment for treatment, and maternal and neonatal characteristics (all P > 0.05). Health of the children in terms of hospital admission and surgical intervention rates were comparable between the vitrification and fresh group (both P > 0.05).

LIMITATIONS, REASONS FOR CAUTION

Although the current study is the largest series describing health parameters beyond the neonatal period, the small numbers still preclude definite conclusions.

WIDER IMPLICATIONS OF THE FINDINGS

This study provides the first evidence indicating that oocyte vitrification does not adversely affect the growth and health of offspring beyond the neonatal period.

STUDY FUNDING/COMPETING INTEREST(S)

This study was supported by Methusalem grants and by grants from Wetenschappelijk Fonds Willy Gepts, all issued by the Vrije Universiteit Brussel. All co-authors declared no conflict of interest in relation to this work. Both the Centre for Reproductive Medicine and the Centre for Medical Genetics from the UZ Brussel have received several educational grants from IBSA, Ferring, MSD and Merck for either research on oocyte vitrification or for establishing the database for follow-up research and organizing the data collection.

Blood pressure trajectories during pregnancy and associations with adverse birth outcomes among HIV-infected and HIV-uninfected women in South Africa: a group-based trajectory modelling approach

BACKGROUND

High blood pressure (BP) late in pregnancy is associated with preterm delivery (PTD); BP has also been associated with HIV and antiretroviral therapy (ART), but whether the relationship between BP assessed longitudinally over pregnancy and PTD and low birthweight (LBW) is modified by HIV/ART is unclear. We hypothesise the presence of distinctive BP trajectories and their association with adverse birth outcomes may be mediated by HIV/ART status.

METHODS

We recruited pregnant women at a large primary care facility in Cape Town. BP was measured throughout pregnancy using automated monitors. Group-based trajectory modelling in women with ≥3 BP measurements identified distinct joint systolic and diastolic BP trajectory groups. Multinomial regression assessed BP trajectory group associations with HIV/ART status, and Poisson regression with robust error variance was used to assess risk of PTD and LBW.

RESULTS

Of the 1583 women in this analysis, 37% were HIV-infected. Seven joint trajectory group combinations were identified, which were categorised as normal (50%), low normal (25%), high normal (20%), and abnormal (5%). A higher proportion of women in the low normal group were HIV-infected than HIV-uninfected (28% vs. 23%), however differences were not statistically significant (RR 1.27, 95% CI 0.98-1.63, reference category: normal). In multivariable analyses, low normal trajectory (aRR0.59, 0.41-0.85) was associated with decreased risk of PTD, while high normal (aRR1.48, 1.12-1.95) and abnormal trajectories (aRR3.18, 2.32-4.37) were associated with increased risk of PTD, and abnormal with increased risk of LBW (RR2.81, 1.90-4.15).

CONCLUSIONS

While HIV/ART did not appear to mediate the BP trajectories and adverse birth outcomes association, they did provide more detailed insights into the relationship between BP, PTD and LBW for HIV-infected and uninfected women.

Assessing multidimensional care coverage for pre-eclampsia in the era of universal health coverage: A pre-post evaluation of the Salud Mesoamérica Initiative

Objective

To compare a multidimensional care package for pre‐eclampsia/eclampsia in Central American health facilities, before and after implementation of the Salud Mesoamérica Initiative.

Methods

An evaluation study was conducted at 67 basic‐ and comprehensive‐level health facilities serving the poorest areas in Honduras, Nicaragua, and Belize. Cases of severe pre‐eclampsia or eclampsia were randomly sampled and relevant quality of care data extracted from medical records at baseline (n=111) from January 1, 2011, to March 31, 2013, and at second‐phase follow‐up (n=249) from June 1, 2015, to September 30, 2017. The primary outcome was evidence of the delivery of multidimensional care for the management of pre‐eclampsia/eclampsia.

Results

The care of 360 women with severe pre‐eclampsia or eclampsia was analyzed. Odds of multidimensional care for pre‐eclampsia management (P=0.271) increased (although not significantly) in the second‐phase follow‐up compared to baseline. Multidimensional care was significantly associated with training (P<0.001), basic‐level facilities (P<0.001), and higher in Honduras (P=0.001) and Belize (P=0.024) than the reference country of Nicaragua.

Conclusion

Multidimensional care for pre‐eclampsia management increased across all facility types, countries, and severity of disease. The Salud Mesoamérica Initiative is a promising model for achieving such quality of care interventions in the era of universal health coverage.

Multidimensional care for pre‐eclampsia management increased across all facility types, participating countries, and severity of disease under the Salud Mesoamérica Initiative model in Central America.

The outcome of hypertensive disorders with pregnancy

BACKGROUND

Hypertensive disorders (HTDs) with pregnancy remain a major health problem because of the associated adverse maternal and perinatal adverse outcomes.

OBJECTIVES

To evaluate the outcomes of HTDs with pregnancy.

PATIENTS AND METHODS

Four hundred and five (405) hypertensive women included in this retrospective multicenter study. Data of the studied women including maternal age, parity, gestational age at delivery, pregnancy outcome [preterm delivery (PTD), birth weight (LBW), Apgar scores, neonatal intensive care unit admission (NICU), intrauterine fetal death (IUFD), intrapartum and/or early neonatal deaths] were collected. Collected data analyzed statistically to evaluate the outcome of HTDs with pregnancy.

RESULTS

Preeclampsia (PE)/superimposed PE group had significantly high relative risk (RR) and Odds ratio (OR) for PTD (RR 2.1; OR; 3.3; P = 0.0001 and P = 0.0001, respectively), LBW (RR 2.01; OR; 3.17; P = 0.0001 and P = 0.0001, respectively), and low Apgar score at 1st min (RR 1.7; OR 1.9; P = 0.01 and 0.01, respectively) and at 5th min (RR 2.2; OR; 2.36; P = 0.2 and 0.2; respectively). In addition, PE/superimposed PE group had significantly high RR and OR for NICU admission (RR 1.6; OR 2.2; P < 0.0002 and P < 0.0001, respectively) and IUFD (RR 2.9; OR 3.1; P = 0.01 and 0.01, respectively).

CONCLUSION

women with PE/superimposed PE have high RR and OR for PTD, LBW, and low Apgar score at 1st and 5th min, NICU, and IUFD compared to the gestational and chronic hypertension with pregnancy.

Household fuel use and adverse pregnancy outcomes in a Ghanaian cohort study

BACKGROUND

Accruing epidemiological evidence suggests that prenatal exposure to emissions from cooking fuel is associated with increased risks of adverse maternal and perinatal outcomes including hypertensive disorders of pregnancy, low birth weight, stillbirth and infant mortality. We aimed to investigate the relationship between cooking fuel use and various pregnancy related outcomes in a cohort of urban women from the Accra region of Ghana.

METHODS

Self-reported cooking fuel use was divided into "polluting" (wood, charcoal, crop residue and kerosene) and "clean" fuels (liquid petroleum gas and electricity) to examine 12 obstetric outcomes in a prospective cohort of pregnant women (N = 1010) recruited at < 17 weeks of gestation from Accra, Ghana. Logistic and multivariate linear regression analyses adjusted for BMI, maternal age, maternal education and socio-economic status asset index was conducted.

RESULTS

34% (n = 279) of 819 women with outcome data available for analysis used polluting fuel as their main cooking fuel. Using polluting cooking fuels was associated with perinatal mortality (aOR: 7.6, 95%CI: 1.67-36.0) and an adverse Apgar score (< 7) at 5 min (aOR:3.83, 95%CI: (1.44-10.11). The other outcomes (miscarriage, post-partum hemorrhage, pre-term birth, low birthweight, caesarian section, hypertensive disorders of pregnancy, small for gestational age, and Apgar score at 1 min) had non-statistically significant findings.

CONCLUSIONS

We report an increased likelihood of perinatal mortality, and adverse 5-min Apgar scores in association with polluting fuel use. Further research including details on extent of household fuel use exposure is recommended to better quantify the consequences of household fuel use.

Prevalence of hypertensive disorders of pregnancy and pregnancy outcomes in Sub-Saharan Africa: A systematic review and meta-analysis

Hypertensive disorders of pregnancy are one of the leading causes of poor pregnancy outcomes and are associated with increased rates of maternal mortality, preterm birth, small for gestational age newborns, stillbirth, and neonatal death. The overall and type-specific prevalence of hypertensive disorders of pregnancy and associated pregnancy outcomes are unknown in Sub-Saharan Africa. Therefore, this review aimed to identify the prevalence of hypertensive disorders of pregnancy and associated pregnancy outcomes in Sub-Saharan Africa. A systematic review and meta-analysis were conducted on observational facility-based studies irrespective of publication status, sample size, language, and follow-up duration from 19 countries between the years 2000 and 2018 in Sub-Saharan Africa. A review of studies using PubMed, EMBASE, African Index Medicus, and African Journals Online was completed with independent extraction of studies by review authors using the predefined inclusion criteria. Quality and risk of bias of individual studies were assessed using the Joanna Briggs Institute Checklist. Random effects model was used to estimate the pooled prevalence of hypertensive disorders of pregnancy and type-specific hypertensive disorders of pregnancy. A pooled adjusted odds ratio with 95% confidence interval for each study was calculated using comprehensive meta-analysis version 2 software to estimate the association of hypertensive disorders of pregnancy and its outcomes. The existence of heterogeneity was assessed using I2 and its corresponding P value. We assessed the presence of publication bias using the Egger's test. Subgroup analysis was performed to assess the potential effect of variables, and a sensitivity analysis was conducted to assess any undue influence from studies. The analysis included 70 studies. The pooled prevalence of hypertensive disorders of pregnancy (all types combined), chronic hypertension, gestational hypertension, preeclampsia, and eclampsia were 8% (95% confidence interval = [5, 10]), 0.9% (95% confidence interval = [0.4, 1.8]), 4.1% (95% confidence interval = [2.4, 7]), 4.1% (95% confidence interval = [3.2, 5.1]), and 1.5% (95% confidence interval = [1, 2]), respectively. Compared with normotensive pregnant or postpartum women, women with hypertensive disorders of pregnancy were associated with increased risk of maternal mortality, odds ratio = 17 (95% confidence interval = [9.6, 28.8]); cesarean section, odds ratio = 3.1 (95% confidence interval = [1.7, 5.6]); perinatal mortality, odds ratio = 8.2 (95% confidence interval = [2.8, 24]); low birth weight, odds ratio = 3.2 (95% confidence interval = [2, 5]); and preterm delivery, odds ratio = 7.8 (95% confidence interval = [2.5, 25.3]) according to this analysis. The pooled prevalence of hypertensive disorders of pregnancy was high in Sub-Saharan Africa compared to those reported from other regions. Pregnant or postpartum women with hypertensive disorders of pregnancy have increased risk of maternal mortality, cesarean section, preterm delivery, perinatal mortality, and low birth weight newborn. Therefore, creating awareness of the risks of hypertensive disorders of pregnancy is essential. Pregnant women with hypertensive disorders need due attention to manage appropriately and more importantly to have favorable outcomes in this population.

Maternal and perinatal outcomes of hypertensive disorders of pregnancy in Ethiopia: systematic review and meta-analysis

BACKGROUND

Hypertensive disorders of pregnancy complicate around 6% of pregnancies and accounts for 19% of maternal death in Ethiopia. The current review aimed to assess maternal and perinatal outcomes of pregnancies complicated by hypertension in Ethiopia.

METHODS

A systematic review and meta-analysis was done on the outcome of hypertensive disorder among pregnant women in Ethiopia. Literature search was made in five databases and Statistical analyses were carried out by using Stata 14 software. The pooled prevalence of maternal death, HELLP syndrome, perinatal death, and low birth weight was calculated using a random-effects model. Egger's test and funnel plot were used to evaluate publication bias. The Cochran Q test and I2 test statistics were used to test the heterogeneity of studies.

RESULT

Thirteen studies included in the review, with an overall sample size of 5894 women diagnosed to have hypertensive disorder of pregnancy. The pooled prevalence of maternal death was estimated to be 4% (95% CI: 2, 6%). The pooled prevalence of HELLP syndrome was 13% (95% CI: 10, 16%). Other complications such as pulmonary edema, kidney injury, hepatic injury, placental abruption, and aspiration pneumonia were also reported. Perinatal death was observed in one-fourth of women with HDP 25% (95% CI: 18, 32%). The pooled prevalence of low birth weight neonate in a woman with HDP is 37% (95% CI, 27, 48%).

CONCLUSIONS

In Ethiopia, the prevalence of perinatal and maternal mortality among pregnant women with one of the hypertensive disorders were found to be higher than rates reported from high income as well as most of the low and middle income countries. For instance, one in four of pregnancies complicated by hypertensive disorder end up in perinatal death in Ethiopia. HELLP syndrome, placental abruption, pulmonary edema, renal damage, prematurity, perinatal asphyxia, and low birth weight were also commonly reported. To improve the health outcomes of hypertensive disorders of pregnancy, it is recommended to improve utilization of maternal health service; early detection and early referral of pregnant women with hypertensive disorder; advocating policies and strategies that improves the quality of health care that a pregnant woman and her newborn receive.

Maternal and perinatal outcomes among women with hypertensive disorders in pregnancy in Kumasi, Ghana

BACKGROUND

Data pertaining to maternal and perinatal outcomes associated with the complete spectrum of hypertensive disorders in pregnancy (HDPs) is sparse in low resource settings. This study aimed to determine adverse maternal and perinatal outcomes among women admitted with HDPs in a tertiary hospital in Ghana, and directly compare these outcomes among women with pre-eclampsia/eclampsia and those with chronic/gestational hypertension.

METHODS

An analytical cross-sectional study was conducted among women who were admitted with HDPs to Komfo Anokye Teaching Hospital from July 1, 2014 to September 30, 2014. Data was collected on their socio-demographic and reproductive characteristics using a pretested structured questionnaire and review of their antenatal records. Crude and adjusted relative risks (RRs), with 95% confidence intervals (CIs), associated with adverse maternal and perinatal outcomes were compared using multivariable binomial regression. P ≤0.05 was considered statistically significant.

RESULTS

A total of 451 women with HDPs were studied: 5.3%, 32.4%, 48.8% and 13.5% had chronic hypertension, gestational hypertension, pre-eclampsia and eclampsia respectively. Over 80% were either referrals or "self-referred" from other facilities. Overall, 87% had adverse maternal or perinatal outcomes. Women with pre-eclampsia/eclampsia were at increased risks of caesarean section (adjusted RR, 1.37; 95% CI, 1.01-1.87), preterm delivery at <34 weeks' gestation (adjusted RR, 2.74; 95% CI, 1.40-5.36) and preterm delivery at <37 weeks' gestation (adjusted RR, 1.89; 95% CI, 1.25-2.85), compared to women with chronic/gestational hypertension.

CONCLUSION

Women with pre-eclampsia/eclampsia were at higher risk of adverse pregnancy outcome compared to those with chronic/gestational hypertension. Strategies for prevention and management of pre-eclampsia/eclampsia to improve pregnancy outcomes are required in this major maternity care centre.

Equity in maternal health outcomes in a middle-income urban setting: a cohort study

BACKGROUND

Low socioeconomic status (SES) is associated with more adverse perinatal health outcomes, risk factors and lower access to and use of maternal health care services. However, evidence for the association between SES and maternal health outcomes is limited, particularly for middle-income countries like sub-Saharan Ghana. We assessed the association between parental SES and adverse maternal and perinatal outcomes of Ghanaian women during pregnancy, delivery and the postpartum period.

METHODS

A prospective cohort study of 1010 women of two public hospitals in Accra, Ghana (2012-2014). SES was proxied by maternal and paternal education, wealth and employment status. The association of SES with maternal and perinatal outcomes was analyzed with multivariable logistic and linear regression.

RESULTS

The analysis included 790 women with information on pregnancy outcomes. Average age was 28.2 years (standard deviation, SD 5.0). Over a third (n = 292, 37.0%) had low SES, 176 (22.3%) were classified to have high SES using the assets index. Nearly half (n = 374, 47.3%) of women had lower secondary school or vocational training as highest education level. Compared to women with middle assets SES, women with low assets SES were at higher risk for miscarriage (odds ratio, OR 1.61, 95% CI 1.06 to 2.45) and instrumental delivery (OR 1.74, 95% CI 1.03 to 2.94), but this association was not observed for the other SES proxies. For any of the maternal or perinatal outcomes and SES proxies, no other statistically significant differences were found.

CONCLUSION

Women attending public maternal health care services in urban Ghana had overall equitable maternal and perinatal health outcomes, with the exception of a higher risk of miscarriage and instrumental delivery associated with low assets SES. This suggests known associations between SES, risk factors and outcomes could be mitigated with universal and accessible maternal health services.

Risk of small for gestational age babies in preterm delivery due to pregnancy-induced hypertension

BACKGROUND Pregnancy-induced hypertension (PIH) causes high maternal morbidity and mortality worldwide. This study aims to assess the impact of PIH on fetal growth according to gestational age in preterm deliveries.METHODS A prospective cohort study using secondary data was undertaken in Ende District, East Nusa Tenggara, Indonesia from September 2014 to August 2015. The t-test was performed to compare mean birth weight based on gestational week between normotensive and PIH women, continued by linear regression. The chi-square or Fisher exact test was also conducted to determine the probability of birthing small for the gestational age (SGA) and large for gestational age (LGA) babies between normotensive and PIH women.RESULTS A total of 1,673 deliveries were recorded in Ende Hospital over the 1-year study period, among which 182 cases involved preterm births. The PIH group had lower birth weight than normotensive women at each gestational age starting from 32–35 weeks (p=0.004; 95% CI 150.84–771.36). Normotensive women at gestational ages of 32 (p=0.05; 95% CI 0.01–0.83), 34 (p=0.37; 95% CI 0.01–4.12), and 36 (p=0.31; 95% CI 0.02–2.95) weeks had a lower risk of birthing SGA babies than PIH women; LGA babies were recorded at gestational ages of 33 (p=1.00; 95% CI 0.07–37.73) and 35 (p=0.31; 95% CI 0.34–63.07) weeks.CONCLUSIONS Poor perfusion of the uteroplacental is one of the reasons behind intrauterine growth restriction, which results in SGA babies born to PIH women.

A Retrospective Study of Neonatal Outcome in Preeclampsia at the University Hospital of the West Indies: A Resource-limited Setting

AIM

This study aimed to determine the outcome of neonates born to women with preeclampsia at the University Hospital of the West Indies (UHWI).

METHODS

This was a retrospective descriptive study looking at the outcome of all babies born to women with preeclampsia and control babies born to normotensive women at the UHWI over a 20-month period. Maternal and neonatal demographic data and course of admission for admitted neonates were recorded. Descriptive analyses were performed.

RESULTS

Neonates born to women with preeclampsia were more likely to be low birth weight [odds ratio (OR = 2.8; confidence interval (CI): 2.2-3.5], small for gestational age (OR = 2.3; CI: 1.9-2.9) or premature (OR = 2.5; CI: 2.0-3.0). They had a lower mean 5 min Apgar score than babies born to normotensive women p<0.05. They were also more likely to be admitted to the neonatal unit 67 (59%) compared with neonates of normotensive women 13 (13%) p<0.001. The main reason for admission was prematurity. Eighteen neonates, all born to women with preeclampsia, died, and the main cause of death was prematurity.

CONCLUSION

Adverse neonatal outcome was noted in neonates born to women with preeclampsia, and this was predominantly related to prematurity and its complications.

Maternal Serum Uric Acid as a Predictor of Severity of Hypertensive Disorders of Pregnancy: A Prospective Cohort Study

Objective: To assess the relationship between maternal serum uric acid and severity of Hypertensive disorders of pregnancy in a rural tertiary care centre.

Materials and Methods: Present study was conducted in Obstetrics and Gynaecology department of rural tertiary care cen-tre of Northern India over seven months (October 2016-May 2017) on 110 women admitted with a Hypertensive disorder of pregnancy (Gestational hypertension, Pre-eclampsia, Eclampsia) at ≥34 weeks gestation. Maternal serum uric acid levels were compared in three groups in relation to disease severity, mode of delivery, maternal outcome.

Results: Of total 110 women with a Hypertensive disorder of pregnancy; 35 (31.81%) had Gestational Hypertension, 49 (44.54%) preeclampsia and 26 (23.63%) had eclampsia. Mean±SD values for serum uric acid were 5.47±1.93 mg/dl in women with Gestational Hypertension; 6.72±2.15 mg/dl in Pre-eclampsia and 8.71±2.97 mg/dl in the eclamptic group. Of 110 women 34(97.14%) with gestational hypertension, 27(55.10%) with pre-eclampsia and one (3.85%) with eclampsia re-mained stable in post-partum period, 17 (34.69%) women with severe pre-eclampsia and 15 (57.69%) with eclampsia re-quired intensive care in postpartum period and one (2.86%) women with gestational hypertension, five (10.20%) with pre-eclmapsia and ten (38.46%) with eclampsia required ventilator support and high dependency unit care. Of these 16 women with the severe disease, ten succumbed to death. Also, in women with serum uric acid,>6mg/dl, most common mode of de-livery was a lower segment cesarean section (50.90%).

Conclusion: Significant correlation was observed between maternal serum uric acid, disease severity and maternal outcome.

Standardizing the measurement of maternal morbidity: Pilot study results

Objective

To field test a standardized instrument to measure nonsevere morbidity among antenatal and postpartum women.

Methods

A cross‐sectional study was conducted in Jamaica, Kenya, and Malawi (2015–2016). Women presenting for antenatal care (ANC) or postpartum care (PPC) were recruited if they were at least 28 weeks into pregnancy or 6 weeks after delivery. They were interviewed and examined by a doctor, midwife, or nurse. Data were collected and securely stored electronically on a WHO server. Diagnosed conditions were coded and summarized using ICD‐MM.

Results

A total of 1490 women (750 ANC; 740 PPC) averaging 26 years of age participated. Most women (61.6% ANC, 79.1% PPC) were healthy (no diagnosed medical or obstetric conditions). Among ANC women with clinical diagnoses, 18.3% had direct (obstetric) conditions and 18.0% indirect (medical) problems. Prevalences among PPC women were lower (12.7% and 8.6%, respectively). When screening for factors in the expanded morbidity definition, 12.8% (ANC) and 11.0% (PPC) self‐reported exposure to violence.

Conclusion

Nonsevere conditions are distinct from the leading causes of maternal death and may vary across pregnancy and the puerperium. This effort to identify and measure nonsevere morbidity promotes a comprehensive understanding of morbidity, incorporating maternal self‐reporting of exposure to violence, and mental health. Further validation is needed.

A pilot study of a novel instrument to holistically measure maternal morbidity found that nonsevere conditions are distinct from the leading causes of maternal death.

Prepregnancy body mass index, gestational weight gain, and birth weight in the BRISA cohort

OBJECTIVE To analyze the effects of maternal pre-pregnancy body mass index and weight gain during pregnancy on the baby's birth weight. METHODS We conducted a cross-sectional study with 5,024 mothers and their newborns using a Brazilian birth cohort study. In the proposed model, estimated by structural equation modeling, we tested socioeconomic status, age, marital status, pre-pregnancy body mass index, smoking habit and alcohol consumption during pregnancy, hypertension and gestational diabetes, gestational weight gain, and type of delivery as determinants of the baby's birth weight. RESULTS For a gain of 4 kg/m2 (1 Standard Deviation [SD]) in pre-pregnancy body mass index, there was a 0.126 SD increase in birth weight, corresponding to 68 grams (p < 0.001). A 6 kg increase (1 SD) in gestational weight gain represented a 0.280 SD increase in newborn weight, correponding to 151.2 grams (p < 0.001). The positive effect of pre-pregnancy body mass index on birth weight was direct (standardized coefficient [SC] = 0.202; p < 0.001), but the negative indirect effect was small (SC = -0.076, p < 0.001) and partially mediated by the lower weight gain during pregnancy (SC = -0.070, p < 0.001). The positive effect of weight gain during pregnany on birth weight was predominantly direct (SC = 0.269, p < 0.001), with a small indirect effect of cesarean delivery (SC = 0.011; p < 0.001). Women with a higher pre-pregnancy body mass index gained less weight during pregnancy (p < 0.001). CONCLUSIONS The effect of gestational weight gain on the increase in birth weight was greater than that of pre-pregnancy body mass index.

Antepartum complications and perinatal mortality in rural Bangladesh

BACKGROUND

Despite impressive improvements in maternal survival throughout the world, rates of antepartum complications remain high. These conditions also contribute to high rates of perinatal deaths, which include stillbirths and early neonatal deaths, but the extent is not well studied. This study examines patterns of antepartum complications and the risk of perinatal deaths associated with such complications in rural Bangladesh.

METHODS

We used data on self-reported antepartum complications during the last pregnancy and corresponding pregnancy outcomes from a household survey (N = 6,285 women) conducted in Sylhet district, Bangladesh in 2006. We created three binary outcome variables (stillbirths, early neonatal deaths, and perinatal deaths) and three binary exposure variables indicating antepartum complications, which were antepartum hemorrhage (APH), probable infection (PI), and probable pregnancy-induced hypertension (PIH). We then examined patterns of antepartum complications and calculated incidence rate ratios (IRR) to estimate the associated risks of perinatal mortality using Poisson regression analyses. We calculated population attributable fraction (PAF) for the three antepartum complications to estimate potential risk reductions of perinatal mortality associated them.

RESULTS

We identified 356 perinatal deaths (195 stillbirths and 161 early neonatal deaths). The highest risk of perinatal death was associated with APH (IRR = 3.5, 95% CI: 2.4-4.9 for perinatal deaths; IRR = 3.7, 95% CI 2.3-5.9 for stillbirths; IRR = 3.5, 95% CI 2.0-6.1 for early neonatal deaths). Pregnancy-induced hypertension was a significant risk factor for stillbirths (IRR = 1.8, 95% CI 1.3-2.5), while PI was a significant risk factor for early neonatal deaths (IRR = 1.5, 95% CI 1.1-2.2). Population attributable fraction of APH and PIH were 6.8% and 10.4% for perinatal mortality and 7.5% and 14.7% for stillbirths respectively. Population attributable fraction of early neonatal mortality due to APH was 6.2% and for PI was 7.8%.

CONCLUSIONS

Identifying antepartum complications and ensuring access to adequate care for those complications are one of the key strategies in reducing perinatal mortality in settings where most deliveries occur at home.

Hypertensive disease in pregnancy in Botswana: Prevalence and impact on perinatal outcomes

OBJECTIVES

Perinatal morbidity in sub-Saharan Africa has been attributed to infection, obstetric emergencies, and preterm birth, but less is known about hypertension in pregnancy. Our objective was to characterize the prevalence of hypertension in pregnancy and the impact of hypertension on perinatal outcomes in sub-Saharan Africa.

STUDY DESIGN

We performed surveillance of obstetric records at eight of the largest public hospitals in Botswana. Women were included in this analysis if they were HIV-uninfected and had singleton gestations and at least one prenatal blood pressure measurement.

MAIN OUTCOME MEASURES

We measured stillbirth, preterm birth, small for gestational age, and neonatal death in women with and without hypertension in pregnancy.

RESULTS

We included 14,170 pregnancies. Hypertension occurred in 3156 (22.2%) women, with 602 (19.1%) defined as severe. Severe hypertension increased risk of stillbirth (RR 4.4; 95% CI 3.2-6.2), preterm birth (RR 2.5; 95% CI 2.2-2.8), small for gestational age (RR 2.7; 95% CI 2.3-3.1) and neonatal death (RR 5.1; 95% CI 2.9-5.6). Non-severe hypertension increased risk of stillbirth (RR 2.0; 95% CI 1.5-2.7), preterm birth (RR 1.2; 95% CI 1.1-1.3), and small for gestational age (RR 1.6; 95% CI 1.4-1.8). Perinatal outcomes were worse in women with hypertension who had spontaneous preterm birth compared to those who underwent iatrogenic preterm delivery.

CONCLUSIONS

Hypertension in pregnancy is common in Botswana and leads to a large number of adverse outcomes. Improved management of hypertension in pregnancy may improve perinatal morbidity and mortality.
