Stillbirth rates in 20 countries of Latin America: an ecological study

Objective: To describe country-level stillbirth rates and their change over time in Latin America, and to measure the association of stillbirth rates with socio-economic and health coverage indicators in the region. Design: Ecological study. Setting: 20 countries of Latin America. Population or Sample: Aggregated data from pregnant women with countries as units of analysis. Methods: We used stillbirth estimates, and socio-economic and healthcare coverage indicators reported from 2006 to 2016 from UNICEF, United Nations Development Programme and World Bank datasets. We calculated Spearman's correlation coefficients between stillbirths rates and socioeconomic and health coverage indicators. Main outcome measures: National estimates of stillbirth rates in each country. Results: The estimated stillbirth rate for Latin America for 2015 was 8.1 per 1000 births (range 3.1–24.9). Seven Latin America countries had rates higher than 10 stillbirths per 1000 births. The average annual reduction rate for the region was 2% (range 0.1–3.8%), with the majority of Latin America countries ranging between 1.5 and 2.5%. National stillbirth rates were correlated to: women's schooling (rS = −0.7910), gross domestic product per capita (rS = −0.8226), fertility rate (rS = 0.6055), urban population (rS = −0.6316), and deliveries at health facilities (rS = −0.6454). Conclusions: Country-level estimated stillbirth rates in Latin America varied widely in 2015. The trend and magnitude of reduction in stillbirth rates between 2000 and 2015 was similar to the world average. Socio-economic and health coverage indicators were correlated to stillbirth rates in Latin America. Tweetable abstract: Stillbirth rates decreased in Latin America but remain relatively high, with wide variations among countries.Fil: Pingray, María Verónica.

The increasing trend in preterm birth in public hospitals in northern Argentina

Objective: To identify factors associated with the increasing incidence of preterm birth in northern Argentina. Methods: In an observational study, data were reviewed from a prospective, population-based registry of pregnancy outcomes in six cities in 2009-2012. The primary outcome was preterm birth (at 20-37 weeks). Bivariate tests and generalized estimating equations were used within a conceptual hierarchical framework to estimate the cluster-corrected annual trend in odds of preterm birth. Results: The study reviewed data from 11 433 live births. There were 484 (4.2%) preterm births. The incidence of preterm births increased by 38% between 2009 and 2012, from 37.5 to 51.7 per 1000 live births. Unadjusted risk factors for preterm birth included young or advanced maternal age, normal body mass index, nulliparity, no prenatal care, no vitamins or supplements during pregnancy, multiple gestation, and maternal hypertension or prepartum hemorrhage. The prevalence of many risk factors increased over the study period, but variations in these factors explained less than 1% of the increasing trend in preterm birth. Conclusion: The incidence of preterm births insix small cities in northern Argentina increased greatly between 2009 and 2012. This trend was unexplained by the risk factors measured. Other factors should be assessed in future studies.Fil: Weaver, Emily H.. University of North Carolina School at Chapel Hill; Estados UnidosFil: Gibbons, Luz.

Reducing neonatal mortality associated with preterm birth: gaps in knowledge of the impact of antenatal corticosteroids on preterm birth outcomes in low-middle income countries

The Global Network’s Antenatal Corticosteroids Trial (ACT), was a multi-country, cluster-randomized trial to improve appropriate use of antenatal corticosteroids (ACS) in low-resource settings in low-middle income countries (LMIC). ACT substantially increased ACS use in the intervention clusters, but the intervention failed to show benefit in the targeted < 5th percentile birth weight infants and was associated with increased neonatal mortality and stillbirth in the overall population. In this issue are six papers which are secondary analyses related to ACT that explore potential reasons for the increase in adverse outcomes overall, as well as site differences in outcomes. The African sites appeared to have increased neonatal mortality in the intervention clusters while the Guatemalan site had a significant reduction in neonatal mortality, perhaps related to a combination of ACS and improving obstetric care in the intervention clusters. Maternal and neonatal infections were increased in the intervention clusters across all sites and increased infections are a possible partial explanation for the increase in neonatal mortality and stillbirth in the intervention clusters, especially in the African sites. The analyses presented here provide guidance for future ACS trials in LMIC. These include having accurate gestational age dating of study subjects and having care givers who can diagnose conditions leading to preterm birth and predict which women likely will deliver in the next 7 days. All study subjects should be followed through delivery and the neonatal period, regardless of when they deliver. Clearly defined measures of maternal and neonatal infection should be utilized. Trials in low income country facilities including clinics and those without newborn intensive care seem to be of the highest priority.Fil: McClure, Elizabeth M..

Women’s preferences and mode of delivery in public and private hospitals: a prospective cohort study

Background Rates of caesarean section have steadily increased in most middle- and high-income countries over the last few decades without medical justification. Maternal request is one of the frequently cited non-medical factors contributing to this trend. The objectives of this study were to assess pregnant women’s preferences regarding mode of delivery and to compare actual caesarean section rates in the public and private sectors. Methods A prospective cohort study was conducted in two public and three private hospitals in Buenos Aires, Argentina. 382 nulliparous pregnant women (183 from the private sector and 199 from the public sector) aged 18 to 35 years, with single pregnancies over 32 weeks of gestational age were enrolled during antenatal care visits between October 2010 and September 2011. We excluded women with pregnancies resulting from assisted fertility, women with known pre-existing major diseases or, with pregnancy complications, or with a medical indication of elective cesarean section. We used two different approaches to assess women’s preferences: a survey using a tailored questionnaire, and a discrete choice experiment. Results Only 8 and 6 % of the healthy nulliparous women in the public and private sectors, respectively, expressed a preference for caesarean section. Fear of pain and safety were the most frequently expressed reasons for preferring caesarean section. When reasons for delivery mode were assessed by a discrete choice experiment, women placed the most emphasis on sex after childbirth. Of women who expressed their preference for vaginal delivery, 34 and 40 % ended their pregnancies by caesarean section in public and private hospitals, respectively. Conclusions The preference for caesarean section is low among healthy nulliparous women in Buenos Aires. The reasons why these women had a rate of more than 35 % caesarean sections are unlikely related to their preferences for mode of delivery.Fil: Mazzoni, Agustina.

Zika virus infection in pregnant women in Honduras: study protocol

Background: Although there is increasing evidence for a relationship between symptomatic Zika virus (ZIKV) maternal infection, and microcephaly, a firm causal relation has yet to be established by epidemiologic studies. Studies also need to be conducted in recently infected settings. Our objectives are to assess the frequency of ZIKV infection during pregnancy in Honduras and the association of microcephaly with ZIKV infection. Methods/Design: We will perform a prospective study enrolling pregnant women at their first antenatal visit and following them up until delivery. At the time of enrollment, women will be interviewed to collect socio-demographic data, data needed to locate them for potential additional follow-up, and data about ZIKV symptoms during pregnancy. We will also collect maternal blood as soon as possible after enrollment. A probable maternal ZIKV infection will be defined as positive for maternal ZIKV IgM. A confirmed maternal ZIKV infection will be defined as positive for ZIKV IgM confirmed by plaque reduction neutralization test. Microcephaly at birth will be defined as an occipito-frontal circumference <2SD for sex and gestational age. Our objective is to enroll 2000 pregnant women. In a first step, we will follow a case cohort design and only analyze blood samples for cases and a sub-cohort of 200 women randomly selected. Blood samples for the entire population will be analyzed at a later stage if funds are available. Discussion: This protocol was designed to be implemented with minimal resources. It allows a cohort to be built, which could be a foundation for future in-depth and follow-up studies.Fil: Buekens, Pierre. University of Tulane; Estados UnidosFil: Alger, Jackeline.

Smoking Patterns and Receipt of Cessation Services Among Pregnant Women in Argentina and Uruguay

Introduction: The 5A’s (Ask, Advise, Assess, Assist, and Arrange) strategy, a best-practice approach for cessation counseling, has been widely implemented in high-income countries for pregnant women; however, no studies have evaluated implementation in middle-income countries. The study objectives were to assess smoking patterns and receipt of 5A’s among pregnant women in Buenos Aires, Argentina and Montevideo, Uruguay. Methods: Data were collected through administered questionnaires to women at delivery hospitalizations during October 2011–May 2012. Eligible women attended one of 12 maternity hospitals or 21 associated prenatal care clinics. The questionnaire included demographic data, tobacco use/cessation behaviors, and receipt of the 5A’s. Self-reported cessation was verified with saliva cotinine. Results: Overall, of 3400 pregnant women, 32.8% smoked at the beginning of pregnancy; 11.9% quit upon learning they were pregnant or later during pregnancy, and 20.9% smoked throughout pregnancy. Smoking prevalence varied by country with 16.1% and 26.7% who smoked throughout pregnancy in Argentina and Uruguay, respectively. Among pregnant smokers in Argentina, 23.8% reported that a provider asked them about smoking at more than one prenatal care visit; 18.5% were advised to quit; 5.3% were assessed for readiness to quit, 4.7% were provided assistance, and 0.7% reported follow-up was arranged. In Uruguay, those percentages were 36.3%, 27.9%, 5.4%, 5.6%, and 0.2%, respectively. Conclusions: Approximately, one in six pregnant women smoked throughout pregnancy in Buenos Aires and one in four in Montevideo. However, a low percentage of smokers received any cessation assistance in both countries. Healthcare providers are not fully implementing the recommended 5A’s intervention to help pregnant women quit smoking.Fil: Berrueta, Amanda Mabel.

Do Italian women prefer cesarean section? Results from a survey on mode of delivery preferences

Background: About 20 million cesareans occur each year in the world and rates have steadily increased in almost all middle- and high-income countries over the last decades. Maternal request is often argued as one of the key forces driving this increase. Italy has the highest cesarean rate of Europe, yet there are no national surveys on the views of Italian women about their preferences on route of delivery. This study aimed to assess Italian women's preference for mode of delivery, as well as reasons and factors associated with this preference, in a nationally representative sample of women.Methods: This cross sectional survey was conducted between December 2010-March 2011. An anonymous structured questionnaire asked participants what was their preferred mode of delivery and explored the reasons for this preference by assessing their agreement to a series of statements. Participants were also asked to what extent their preference was influenced by a series of possible sources. the 1st phase of the study was carried out among readers of a popular Italian women's magazine (Io Donna). in a 2nd phase, the study was complemented by a structured telephone interview.Results: A total of 1000 Italian women participated in the survey and 80% declared they would prefer to deliver vaginally if they could opt. the preference for vaginal delivery was significantly higher among older (84.7%), more educated (87.6%), multiparous women (82.3%) and especially among those without any previous cesareans (94.2%). the main reasons for preferring a vaginal delivery were not wanting to be separated from the baby during the first hours of life, a shorter hospital stay and a faster postpartum recovery. the main reasons for preferring a cesarean were fear of pain, convenience to schedule the delivery and because it was perceived as being less traumatic for the baby. the source which most influenced the preference of these Italian women was their obstetrician, followed by friends or relatives.Conclusion: Four in five Italian women would prefer to deliver vaginally if they could opt. Factors associated with a higher preference for cesarean delivery were youth, nulliparity, lower education and a previous cesarean.Universidade Federal de São Paulo, Dept Obstet, São Paulo, BrazilWHO, Dept Reprod Hlth & Res, CH-1211 Geneva, SwitzerlandOsservatorio Nazl Salute Donna, ONDa, Milan, ItalyInst Clin Effectiveness & Hlth Policy, Buenos Aires, DF, ArgentinaUniv Florence, Meyer Children Hosp, I-50121 Florence, ItalyUniversidade Federal de São Paulo, Dept Obstet, São Paulo, BrazilWeb of Scienc

Provision of medical supply kits to improve quality of antenatal care in Mozambique: a stepped-wedge cluster randomised trial

Background High levels of maternal and newborn mortality and morbidity remain a daunting reality in many low-income countries. Several interventions delivered during antenatal care have been shown to improve maternal and newborn outcomes, but stockouts of medical supplies at point of care can prevent implementation of these services. We aimed to evaluate whether a supply chain strategy based on the provision of kits could improve quality of care. Methods We did a pragmatic, stepped-wedge, cluster-randomised controlled trial at ten antenatal care clinics in Mozambique. Clinics were eligible if they were not already implementing the proposed antenatal care package; they served at least 200 new pregnant women per year; they had Maternal and Child Health (MCH) nurses; and they were willing to participate. All women attending antenatal care visits at the participating clinics were included in the trial. Participating clinics were randomly assigned to shift from control to intervention on prespecified start dates. The intervention involved four components (kits with medical supplies, a cupboard to store these supplies, a tracking sheet to monitor stocks, and a one-day training session). The primary outcomes were the proportion of women screened for anaemia and proteinuria, and the proportion of women who received mebendazole in the first antenatal care visit. The intervention was delivered under routine care conditions, and analyses were done according to the intention-to-treat principle. This trial is registered with the Pan African Clinical Trial Registry, number PACTR201306000550192. Findings Between March, 2014, and January, 2016, 218 277 antenatal care visits were registered, with 68 598 first and 149 679 follow-up visits. We found significant improvements in all three primary outcomes. In first visits, 5519 (14·6%) of 37 826 women were screened for anaemia in the control period, compared with 30 057 (97·7%) of 30 772 in the intervention period (adjusted odds ratio 832·40; 99% CI 666·81–1039·11; p<0·0001); 3739 (9·9%) of 37 826 women were screened for proteinuria in the control period, compared with 29 874 (97·1%) of 30 772 in the intervention period (1875·18; 1447·56–2429·11; p<0·0001); and 17 926 (51·4%) of 34 842 received mebendazole in the control period, compared with 24 960 (88·2%) of 28 294 in the intervention period (1·88; 1·70–2·09; p<0·0001). The effect was immediate and sustained over time, with negligible heterogeneity between sites. Interpretation A supply chain strategy that resolves stockouts at point of care can result in a vast improvement in quality during antenatal care visits, when compared with the routine national process for procurement and distribution of supplies.
