    Background: The Global Network for Women’s and Children’s Health Research is one of the largest international networks for testing and generating evidence-based recommendations for improvement of maternal-child health in resource-limited settings. Since 2009, Global Network sites in six low and middle-income countries have collected information on antenatal care practices, which are important as indicators of care and have implications for programs to improve maternal and child health. We sought to: (1) describe the quantity of antenatal care attendance over a four-year period; and (2) explore the quality of coverage for selected preventative, screening, and birth preparedness components. Methods: The Maternal Newborn Health Registry (MNHR) is a prospective, population-based birth and pregnancy outcomes registry in Global Network sites, including: Argentina, Guatemala, India (Belgaum and Nagpur), Kenya, Pakistan, and Zambia. MNHR data from these sites were prospectively collected from January 1, 2010 – December 31, 2013 and analyzed for indicators related to quantity and patterns of ANC and coverage of key elements of recommended focused antenatal care. Descriptive statistics were generated overall by global region (Africa, Asia, and Latin America), and for each individual site. Results: Overall, 96% of women reported at least one antenatal care visit. Indian sites demonstrated the highest percentage of women who initiated antenatal care during the first trimester. Women from the Latin American and Indian sites reported the highest number of at least 4 visits. Overall, 88% of women received tetanus toxoid. Only about half of all women reported having been screened for syphilis (49%) or anemia (50%). Rates of HIV testing were above 95% in the Argentina, African, and Indian sites. The Pakistan site demonstrated relatively high rates for birth preparation, but for most other preventative and screening interventions, posted lower coverage rates as compared to other Global Network sites. Conclusions: Results from our large, prospective, population-based observational study contribute important insight into regional and site-specific patterns for antenatal care access and coverage. Our findings indicate a quality and coverage gap in antenatal care services, particularly in regards to syphilis and hemoglobin screening. We have identified site-specific gaps in access to, and delivery of, antenatal care services that can be targeted for improvement in future research and implementation efforts.

    A Prospective Cause of Death Classification System for Maternal Deaths in Low and Middle-Income Countries: Results from the Global Network Maternal Newborn Health Registry
    (Wiley, 2017) Pasha, Omrana; McClure, Elizabeth M.; Saleem, Sarah; Sunder, Shiyam; Lokangaka, Adrien; Tshefu, Antoinette; Bose, Carl L.; Bauserman, Melissa; Mwenechanya, Musaku; Chomba, Elwyn; Carlo, Waldemar A.; Garces, Ana L.; Figueroa, Lester; Hambidge, K. Michael; Krebs, Nancy F.; Goudar, Shivaprasad; Kodkany, Bhalachandra S.; Dhaded, Sangappa; Derman, Richard J.; Patel, Archana; Hibberd, Patricia L.; Esamai, Fabian; Tenge, Constance; Liechty, Edward A.; Moore, Janet L.; Wallace, Dennis D.; Koso-Thomas, Marion; Miodovnik, Menachem; Goldenberg, Robert L.; Pediatrics, School of Medicine
    Objective To describe the causes of maternal death in a population-based cohort in six low and middle-income countries using a standardized, hierarchical, algorithmic cause of death (COD) methodology. Design A population-based, prospective observational study. Setting Seven sites in six low-middle income countries including the Democratic Republic of the Congo (DRC), Guatemala, India (2), Kenya, Pakistan and Zambia. Population All deaths amongst pregnant women resident in the study sites from 2014 to December 2016. Methods For women who died, we used a standardized questionnaire to collect clinical data regarding maternal conditions present during pregnancy and delivery. These data were analyzed using a computer-based algorithm to assign cause of maternal death based on the International Classification of Disease - Maternal Mortality system (trauma, abortion-related, eclampsia, hemorrhage, pregnancy-related infection and medical conditions). We also compared the COD results to health care provider assigned maternal COD. Main Outcome Measures Assigned causes of maternal mortality. Results Amongst 158,205 women, there were 221 maternal deaths. The most common algorithm-assigned maternal COD were obstetric hemorrhage (38.6%), pregnancy-related infection (26.4%) and preeclampsia/eclampsia (18.2%). Agreement between algorithm-assigned COD and COD assigned by health care providers ranged from 75% for hemorrhage to 25% for medical causes coincident to pregnancy. Conclusions The major maternal COD in the Global Network sites were hemorrhage, pregnancy-related infection and preeclampsia/eclampsia. This system could allow public health programs in low and middle-income countries to generate transparent and comparable data for maternal COD across time or regions.

    Trends and determinants of stillbirth in developing countries: results from the Global Network’s Population-Based Birth Registry
    (Springer Nature, 2018-06-22) Saleem, Sarah; Tikmani, Shiyam Sunder; McClure, Elizabeth M.; Moore, Janet L.; Azam, Syed Iqbal; Dhaded, Sangappa M.; Goudar, Shivaprasad S.; Garces, Ana; Figueroa, Lester; Marete, Irene; Tenge, Constance; Esamai, Fabian; Patel, Archana B.; Ali, Sumera Aziz; Naqvi, Farnaz; Mwenchanya, Musaku; Chomba, Elwyn; Carlo, Waldemar A.; Derman, Richard J.; Hibberd, Patricia L.; Bucher, Sherri; Liechty, Edward A.; Krebs, Nancy; Hambidge, K. Michael; Wallace, Dennis D.; Koso-Thomas, Marion; Miodovnik, Menachem; Goldenberg, Robert L.; Pediatrics, School of Medicine
    Background: Stillbirth rates remain high, especially in low and middle-income countries, where rates are 25 per 1000, ten-fold higher than in high-income countries. The United Nations' Every Newborn Action Plan has set a goal of 12 stillbirths per 1000 births by 2030 for all countries. Methods: From a population-based pregnancy outcome registry, including data from 2010 to 2016 from two sites each in Africa (Zambia and Kenya) and India (Nagpur and Belagavi), as well as sites in Pakistan and Guatemala, we evaluated the stillbirth rates and rates of annual decline as well as risk factors for 427,111 births of which 12,181 were stillbirths. Results: The mean stillbirth rates for the sites were 21.3 per 1000 births for Africa, 25.3 per 1000 births for India, 56.9 per 1000 births for Pakistan and 19.9 per 1000 births for Guatemala. From 2010 to 2016, across all sites, the mean stillbirth rate declined from 31.7 per 1000 births to 26.4 per 1000 births for an average annual decline of 3.0%. Risk factors for stillbirth were similar across the sites and included maternal age < 20 years and age > 35 years. Compared to parity 1-2, zero parity and parity > 3 were both associated with increased stillbirth risk and compared to women with any prenatal care, women with no prenatal care had significantly increased risk of stillbirth in all sites. Conclusions: At the current rates of decline, stillbirth rates in these sites will not reach the Every Newborn Action Plan goal of 12 per 1000 births by 2030. More attention to the risk factors and treating the causes of stillbirths will be required to reach the Every Newborn Action Plan goal of stillbirth reduction.
