Risk and burden of adverse intrapartum-related outcomes associated with non-cephalic and multiple birth in rural Nepal: a prospective cohort study.

ABSTRACT: OBJECTIVES:Intrapartum-related complications are the second leading cause of neonatal death worldwide. We estimate the community-level risk and burden of intrapartum-related fetal/neonatal mortality and morbidity associated with non-cephalic and multiple birth in rural Sarlahi District, Nepal. DESIGN:Community-based prospective cohort study. SETTING:Rural Sarlahi District, Nepal. PARTICIPANTS:Pregnant women residing in the study area. METHODS:We collected data on maternal background characteristics, conditions during labour and delivery, fetal presentation and multiple birth during home visits. We ran log-binomial regression models to estimate the associations between non-cephalic/multiple births and fresh stillbirth, early neonatal mortality and signs of neonatal encephalopathy, respectively, and calculated the per cent attributable fraction. To better understand the context under which these adverse birth outcomes are occurring, we also collected data on maternal awareness of non-cephalic presentation and multiple gestation prior to delivery. PRIMARY OUTCOME MEASURES:Risk of experiencing fresh stillbirth, early neonatal encephalopathy and early neonatal mortality associated with non-cephalic and multiple birth, respectively. RESULTS:Non-cephalic presentation had a particularly high risk of fresh stillbirth (aRR 12.52 (95% CI 7.86 to 19.95), reference: cephalic presentation). 20.2% of all fresh stillbirths were associated with non-cephalic presentation. For multiple births, there was a fourfold increase in early neonatal mortality (aRR: 4.57 (95% CI 1.44 to 14.50), reference: singleton births). 3.4% of early neonatal mortality was associated with multiple gestation. CONCLUSIONS:Globally and in Nepal, a large percentage of stillbirths and neonatal mortality is associated with intrapartum-related complications. Despite the low incidence of non-cephalic and multiple birth, a notable proportion of adverse intrapartum-related outcomes is associated with these conditions. As the proportion of neonatal deaths attributable to intrapartum-related complications continues to rise, there is a need to investigate how best to advance diagnostic capacity and management of these conditions.

Project description:BACKGROUND:Nausea and vomiting are experienced by a majority of pregnant women worldwide. Previous studies have yielded conflicting results regarding their impact on birth outcomes and few studies have examined this relationship in settings with limited resources. We aimed to determine the effect of nausea, vomiting and poor appetite during pregnancy on birth outcomes in rural Nepal. METHODS:Observational cohort study using data collected in two randomized, community-based trials to assess the effect of influenza immunization during pregnancy on reproductive and respiratory outcomes among pregnant women and their offspring. Pregnant women in Sarlahi District, Nepal were recruited from 2011 to 2013. Exposure was defined as nausea, vomiting or poor appetite at any point during pregnancy and by trimester; symptoms were recorded monthly throughout pregnancy. Adverse outcomes were low birth weight (LBW), preterm birth and small for gestational age (SGA). Adjusted relative risks (aRR) with 95% CIs are reported from Poisson regressions with robust variance. RESULTS:Among 3,623 pregnant women, the cumulative incidence of nausea, vomiting or poor appetite was 49.5% (n?=?1793) throughout pregnancy and 60.6% (n?=?731) in the first trimester. Significantly higher aRRs of LBW and SGA were observed among women experiencing symptoms during pregnancy as compared to symptom free women (LBW: aRR 1.20; 95% CI 1.05 1.28; SGA: aRR 1.16; 95% CI 1.05 1.28). Symptoms in the first trimester were not significantly associated with any of the outcomes. In the second trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.17; 95% CI 1.01 1.36; SGA: aRR 1.16; 95% CI 1.05 1.29) and a significantly lower aRR for preterm birth (aRR 0.75; 95% CI 0.59 0.96). In the third trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.20; 95% CI 1.01 1.43; SGA: aRR 1.14; 95% CI 1.01 1.29). CONCLUSIONS:Symptoms of nausea, vomiting or poor appetite during pregnancy are associated with LBW, SGA and preterm birth in a setting with limited resources, especially beyond the first trimester.

Project description:OBJECTIVES:To estimate the national rate of early-term live births in Brazil and to evaluate the effect of birth at 37 and 38 weeks' gestation, as compared with 39 and 40 weeks' gestation on infant outcomes according to precursors of birth and the existence of maternal/fetal medical conditions. DESIGN:National perinatal population-based cohort study. SETTING:266 maternity services located in the five Brazilian macroregions. PARTICIPANTS:18?652 singleton live newborns from 37 0/7 to 40 6/7 weeks of gestation. MAIN OUTCOME MEASURES:Resuscitation in delivery room, oxygen therapy, transient tachypnoea, admission to neonatal intensive care unit (NICU), hypoglycaemia, use of antibiotics, phototherapy, phototherapy after hospital discharge, neonatal death and breastfeeding. RESULTS:Early terms accounted for 35% (95% CI 33.4% to 36.7%) of all live births. Among provider-initiated births in women without medical conditions, infants of 37 and 38 weeks' gestation had higher odds of oxygen therapy (adjusted OR (AOR) 2.93, 95% CI 1.72 to 4.98 and AOR 1.92?95% CI 1.18 to 3.13), along with admission to NICU (AOR 2.01, 95% CI 1.18 to 3.41 and AOR 1.56, 95% CI 1.02 to 2.60), neonatal death (AOR 14.40, 95% CI 1.94 to 106.69 and AOR 13.76,95% CI 2.84 to 66.75), hypoglycaemia in the first 48?hours of life (AOR 7.86, 95% CI 1.95 to 31.71 and AOR 5.76, 95% CI 1.63 to 20.32), transient tachypnoea (AOR 2.98, 95% CI 1.57 to 5.65 and AOR 2.12, 95% CI 1.00 to 4.48) and the need for phototherapy within the first 72?hours of life (AOR 3.59, 95% CI 1.95 to 6.60 and AOR 2.29, 95% CI 1.49 to 3.53), yet lower odds of breastfeeding up to 1?hour after birth (AOR 0.67, 95% CI 0.53 to 0.86 and AOR 0.87, 95% CI 0.76 to 0.99) and exclusive breastfeeding during hospital stay (AOR 0.68, 95% CI 0.51 to 0.89 and AOR 0.84, 95% CI 0.71 to 0.99). CONCLUSION:Birth at 37 and 38 weeks' gestation increased the risk of most adverse infant outcomes analysed, especially among provider-initiated births and should be avoided before 39 weeks' gestation in healthy pregnancies.

Project description:BACKGROUND:In low-resource settings, a significant proportion of fetal, neonatal, and maternal deaths can be attributed to intrapartum-related complications. Certain risk factors, such as non-cephalic presentation, have a particularly high risk of complications. This qualitative study describes experiences around non-cephalic births and highlights existing perceptions and care-seeking behavior specific to non-cephalic presentation in rural Sarlahi District, Nepal. METHODS:We conducted in-depth interviews with 34 individuals, including women who recently gave birth to a non-cephalic infant and female decision-makers in their households. We also conducted two focus groups with mothers (have two or more children, with at least one child under age five) and two focus groups with grandmothers in the community. RESULTS:Several women described scenes of obstructed labor and practices like provision of unspecified injections early in labor to assist with the delivery. There were reports of arduous care-seeking processes from primary health centers to tertiary facilities, and mixed quality of care among home birth attendants and facility-based health workers respectively. Very few women were aware of the fetal presentation prior to delivery, and we identified no consistent understanding among participants of the risks of and care strategies for non-cephalic births. Risk perception around non-cephalic presentation varied widely. Some participants were acutely aware of potential dangers, while others had not heard of non-cephalic birth. Many interviewees said that the position in which a pregnant woman sleeps could impact the fetal position. Several participants had either taken or heard of medication intended to rotate the fetus into the correct position. CONCLUSIONS:Our findings suggest the mixed quality of and access to care associated with non-cephalic birth and a lack of consistent understanding of the risk of and care for non-cephalic births in rural Nepal. The high risk of the condition and the recommended tertiary care present a dilemma in low-resource settings; the logistical difficulties and the mixed quality of care make care-seeking and referral decisions complex. While public health stakeholders strive to improve the quality of and access to the formal health system, those players must also be sensitive to the potential negative implications of promoting institutional care-seeking.

Project description:BackgroundSignificant and persistent racial and income disparities in birth outcomes exist in the US. The analyses in this manuscript examine whether adverse birth outcome time trends and associations between area-level variables and adverse birth outcomes differ by urban-rural status.MethodsAlabama births records were merged with ZIP code-level census measures of race, poverty, and rurality. B-splines were used to determine long-term preterm birth (PTB) and low birth weight (LBW) trends by rurality. Logistic regression models were used to examine differences in the relationships between ZIP code-level percent poverty or percent African-American with either PTB or LBW. Interactions with rurality were examined.ResultsPopulation dense areas had higher adverse birth outcome rates compared to other regions. For LBW, the disparity between population dense and other regions increased during the 1991-2005 time period, and the magnitude of the disparity was maintained through 2010. Overall PTB and LBW rates have decreased since 2006, except within isolated rural regions. The addition of individual-level socioeconomic or race risk factors greatly attenuated these geographical disparities, but isolated rural regions maintained increased odds of adverse birth outcomes. ZIP code-level percent poverty and percent African American both had significant relationships with adverse birth outcomes. Poverty associations remained significant in the most population-dense regions when models were adjusted for individual-level risk factors.ConclusionsPopulation dense urban areas have heightened rates of adverse birth outcomes. High-poverty African American areas have higher odds of adverse birth outcomes in urban versus rural regions. These results suggest there are urban-specific social or environmental factors increasing risk for adverse birth outcomes in underserved communities. On the other hand, trends in PTBs and LBWs suggest interventions that have decreased adverse birth outcomes elsewhere may not be reaching isolated rural areas.

Project description:BackgroundThe COVID-19 pandemic response is affecting maternal and neonatal health services all over the world. We aimed to assess the number of institutional births, their outcomes (institutional stillbirth and neonatal mortality rate), and quality of intrapartum care before and during the national COVID-19 lockdown in Nepal.MethodsIn this prospective observational study, we collected participant-level data for pregnant women enrolled in the SUSTAIN and REFINE studies between Jan 1 and May 30, 2020, from nine hospitals in Nepal. This period included 12·5 weeks before the national lockdown and 9·5 weeks during the lockdown. Women were eligible for inclusion if they had a gestational age of 22 weeks or more, a fetal heart sound at time of admission, and consented to inclusion. Women who had multiple births and their babies were excluded. We collected information on demographic and obstetric characteristics via extraction from case notes and health worker performance via direct observation by independent clinical researchers. We used regression analyses to assess changes in the number of institutional births, quality of care, and mortality before lockdown versus during lockdown.FindingsOf 22 907 eligible women, 21 763 women were enrolled and 20 354 gave birth, and health worker performance was recorded for 10 543 births. From the beginning to the end of the study period, the mean weekly number of births decreased from 1261·1 births (SE 66·1) before lockdown to 651·4 births (49·9) during lockdown-a reduction of 52·4%. The institutional stillbirth rate increased from 14 per 1000 total births before lockdown to 21 per 1000 total births during lockdown (p=0·0002), and institutional neonatal mortality increased from 13 per 1000 livebirths to 40 per 1000 livebirths (p=0·0022). In terms of quality of care, intrapartum fetal heart rate monitoring decreased by 13·4% (-15·4 to -11·3; p<0·0001), and breastfeeding within 1 h of birth decreased by 3·5% (-4·6 to -2·6; p=0·0032). The immediate newborn care practice of placing the baby skin-to-skin with their mother increased by 13·2% (12·1 to 14·5; p<0·0001), and health workers' hand hygiene practices during childbirth increased by 12·9% (11·8 to 13·9) during lockdown (p<0·0001).InterpretationInstitutional childbirth reduced by more than half during lockdown, with increases in institutional stillbirth rate and neonatal mortality, and decreases in quality of care. Some behaviours improved, notably hand hygiene and keeping the baby skin-to-skin with their mother. An urgent need exists to protect access to high quality intrapartum care and prevent excess deaths for the most vulnerable health system users during this pandemic period.FundingGrand Challenges Canada.
