Effect of the Mamás del Río programme on essential newborn care: a three-year before-and-after outcome evaluation of a community-based, maternal and neonatal health intervention in the Peruvian Amazon.

Background: Despite remarkable progress in maternal and neonatal health, regional inequalities persist in Peru. In rural areas of Amazonian Loreto, access to quality care is difficult, home births are frequent, and neonatal mortality is high. We conducted a prospective before-and-after study to assess the effect after implementation and over time of a community-based intervention on essential newborn care (ENC). Methods: Mamás del Río consists of tablet-enhanced educational home visits by Community health workers (CHW) to pregnant women and mothers of newborns, with supportive training on ENC of traditional birth attendants and facility staff. The study area comprised 79 rural communities of three districts in Loreto. Primary outcomes were ENC practices in home births, secondary outcomes were ENC in facility births as well as healthcare seeking, measured at baseline before and at year 2 and year 3 after intervention implementation. Community censuses included questionnaires to women aged 15-49 years with a live birth. We calculated prevalence of outcomes at each time point and estimated adjusted prevalence differences (PD) between time points using post-estimation based on logistic regression. Findings: Following implementation early 2019, 97% of communities had a trained CHW. At year 2 follow-up, 63% (322/530) of women received a CHW visit during pregnancy. Seven out of nine ENC indicators among home births improved, with largest adjusted prevalence differences in immediate skin-to-skin contact (50% [95% CI: 42-58], p < 0.0001), colostrum feeding (45% [35-54], p < 0.0001), and cord care (19% [10-28], p = 0.0001). Improvements were maintained at year 3, except for cord care. At year 2, among facility births only three ENC indicators improved, while more women gave birth in a facility. Sensitivity analyses showed ENC prevalence was similar before compared to after onset of Covid-19 lockdown. Interpretation: ENC practices in home births improved consistently and changes were sustained over time, despite the onset of the Covid-19 pandemic. A community-based approach for behaviour-change in home-based newborn care appears effective. Process evaluation of mechanisms will help to explain observed effects and understand transferability of findings.

Prevalence of essential newborn care in home and facility births in the Peruvian Amazon: analysis of census data from programme evaluation in three remote districts of the Loreto region.

Background: Essential newborn care (ENC) covers optimal breastfeeding, thermal care, and hygienic cord care. These practices are fundamental to save newborn lives. Despite neonatal mortality remaining high in some parts of Peru, no comprehensive data on ENC is available. We sought to estimate the prevalence of ENC and assess differences between facility and home births in the remote Peruvian Amazon. Methods: We used baseline data from a household census of rural communities of three districts in Loreto region, collected as part of the evaluation of a maternal-neonatal health (MNH) programme. Women between 15 and 49 years with a live birth in the last 12 months were invited to complete a questionnaire about MNH-related care and ENC. Prevalence of ENC was calculated for all births and disaggregated by place of birth. Adjusted prevalence differences (PD) were post-estimated from logistic regression models on the effect of place of birth on ENC. Findings: All 79 rural communities with a population of 14,474 were censused. Among 324 (>99%) women interviewed, 70% gave birth at home, most (93%) without skilled birth assistance. Among all births, prevalence was lowest for immediate skin-to-skin contact (24%), colostrum feeding (47%), and early breastfeeding (64%). ENC was consistently lower in home compared to facility births. After adjusting for confounders, largest PD were found for immediate skin-to-skin contact (50% [95% CI: 38-62]), colostrum feeding (26% [16-36]), and clean cord care (23% [14-32]). ENC prevalence in facilities ranged between 58 and 93%; delayed bathing was lower compared to home births (-19% [-31 to -7]). Interpretation: Low prevalence of ENC practices among home births in a setting with high neonatal mortality and difficult access to quality care in facilities suggests potential for a community-based intervention to promote ENC practices at home, along with promotion of healthcare seeking and simultaneous strengthening of routine facility care.

Triangulating evidence for the causal impact of single-intervention zinc supplement on glycaemic control for type 2 diabetes: systematic review and meta-analysis of randomised controlled trial and two-sample Mendelian randomisation.

Although previous studies suggested the protective effect of Zn for type 2 diabetes (T2D), the unitary causal effect remains inconclusive. We investigated the causal effect of Zn as a single intervention on glycaemic control for T2D, using a systematic review of randomised controlled trials and two-sample Mendelian randomisation (MR). Four primary outcomes were identified: fasting blood glucose/fasting glucose, HbA1c, homeostatic model assessment for insulin resistance (HOMA-IR) and serum insulin/fasting insulin level. In the systematic review, four databases were searched until June 2021. Studies, in which participants had T2D and intervention did not comprise another co-supplement, were included. Results were synthesised through the random-effects meta-analysis. In the two-sample MR, we used single-nucleotide polymorphisms (SNP) from MR-base, strongly related to Zn supplements, to infer the relationship causally, but not specified T2D. In the systematic review and meta-analysis, fourteen trials were included with overall 897 participants initially. The Zn supplement led to a significant reduction in the post-trial mean of fasting blood glucose (mean difference (MD): -26·52 mg/dl, 95 % CI (-35·13, -17·91)), HbA1c (MD: -0·52 %, 95 % CI: (-0·90, -0·13)) and HOMA-IR (MD: -1·65, 95 % CI (-2·62, -0·68)), compared to the control group. In the two-sample MR, Zn supplement with two SNP reduced the fasting glucose (inverse-variance weighted coefficient: -2·04 mmol/l, 95 % CI (-3·26, -0·83)). From the two methods, Zn supplementation alone may causally improve glycaemic control among T2D patients. The findings are limited by power from the small number of studies and SNP included in the systematic review and two-sample MR analysis, respectively.

Readiness of health facilities to provide safe childbirth in Liberia: a cross-sectional analysis of population surveys, facility censuses and facility birth records.

BACKGROUND: The provision of quality obstetric care in health facilities is central to reducing maternal mortality, but simply increasing childbirth in facilities not enough, with evidence that many facilities in sub-Saharan Africa do not fulfil even basic requirements for safe childbirth care. There is ongoing debate on whether to recommend a policy of birth in hospitals, where staffing and capacity may be better, over lower level facilities, which are closer to women's homes and more accessible. Little is known about the quality of childbirth care in Liberia, where facility births have increased in recent decades, but maternal mortality remains among the highest in the world. We will analyse quality in terms of readiness for emergency care and referral, staffing, and volume of births. METHODS: We assessed the readiness of the Liberian health system to provide safe care during childbirth use using three data sources: Demographic and Health Surveys (DHS), Service Availability and Readiness Assessments (SARA), and the Health Management Information System (HMIS). We estimated trends in the percentage of births by location and population caesarean-section coverage from 3 DHS surveys (2007, 2013 and 2019-20). We examined readiness for safe childbirth care among all Liberian health facilities by analysing reported emergency obstetric and neonatal care signal functions (EmONC) and staffing from SARA 2018, and linking with volume of births reported in HMIS 2019. RESULTS: The percentage of births in facilities increased from 37 to 80% between 2004 and 2017, while the caesarean section rate increased from 3.3 to 5.0%. 18% of facilities could carry out basic EmONC signal functions, and 8% could provide blood transfusion and caesarean section. Overall, 63% of facility births were in places without full basic emergency readiness. 60% of facilities could not make emergency referrals, and 54% had fewer than one birth every two days. CONCLUSIONS: The increase in proportions of facility births over time occurred because women gave birth in lower-level facilities. However, most facilities are very low volume, and cannot provide safe EmONC, even at the basic level. This presents the health system with a serious challenge for assuring safe, good-quality childbirth services.

Tracking progress towards universal health coverage for essential health services in China, 2008-2018.

INTRODUCTION: We comprehensively evaluate whether the Chinese Government's goal of ensuring Universal Health Coverage for essential health services has been achieved. METHODS: We used data from the 2008, 2013 and 2018 National Health Services Survey to report on the coverage of a range of Sustainable Development Goals (SDG) indicator 3.8.1. We created per capita household income deciles for urban and rural samples separately. We report time trends in coverage and the slope index (SII) and relative index (RII). RESULTS: Despite much lower levels of income and education, rural populations made as much progress as their urban counterparts for most interventions. Coverage of maternal and child health interventions increased substantially in urban and rural areas, with decreasing rich-poor inequalities except for antenatal care. In rural China, one-fifth women could not access 5 or more antenatal visits. Coverage of 8 or more visits were 34% and 68%, respectively in decile D1 (the poorest) and decile D10 (the richest) (SII 35% (95% CI 22% to 48%)). More than 90% households had access to clean water, but basic sanitation was poor for rural households and the urban poorest, presenting bottom inequality. Effective coverage for non-communicable diseases was low. Medication for hypertension and diabetes were relatively high (>70%). But adequate management, counting in preventive interventions, were much lower and decreased overtime, although inequalities were small in size. Screening of cervical and breast cancer was low in both urban and rural areas, seeing no progress overtime. Cervical cancer screening was only 29% (urban) and 24% (rural) in 2018, presenting persisted top inequalities (SII 25% urban, 14% rural). CONCLUSION: China has made commendable progress in protecting the poorest for basic care. However, the 'leaving no one behind' agenda needs a strategy targeting the entire population rather than only the poorest. Blunt investing in primary healthcare facilities seems neither effective nor efficient.

Does hospital variation in intrapartum-related perinatal mortality among caesarean births reflect differences in quality of care? Cross-sectional study in 21 hospitals in Burkina Faso.

OBJECTIVES: To examine hospital variation in crude and risk-adjusted rates of intrapartum-related perinatal mortality among caesarean births. DESIGN: Secondary analysis of data from the DECIDE (DECIsion for caesarean DElivery) cluster randomised trial postintervention phase. SETTING: 21 district and regional hospitals in Burkina Faso. PARTICIPANTS: All 5134 women giving birth by caesarean section in a 6-month period in 2016. PRIMARY OUTCOME MEASURE: Intrapartum-related perinatal mortality (fresh stillbirth or neonatal death within 24 hours of birth). RESULTS: Almost 1 in 10 of 5134 women giving birth by caesarean experienced an intrapartum-related perinatal death. Crude mortality rates varied substantially from 21 to 189 per 1000 between hospitals. Variation was markedly reduced after adjusting for case mix differences (the median OR decreased from 1.9 (95% CI 1.5 to 2.5) to 1.3 (95% CI 1.2 to 1.7)). However, higher and more variable adjusted mortality persisted among hospitals performing fewer caesareans per month. Additionally, adjusting for caesarean care components did not further reduce variation (median OR=1.4 (95% CI 1.2 to 1.8)). CONCLUSIONS: There is a high burden of intrapartum-related perinatal deaths among caesarean births in Burkina Faso and sub-Saharan Africa more widely. Variation in adjusted mortality rates indicates likely differences in quality of caesarean care between hospitals, particularly lower volume hospitals. Improving access to and quality of emergency obstetric and newborn care is an important priority for improving survival of babies at birth. TRIAL REGISTRATION NUMBER: ISRCTN48510263.

Factors affecting the frequency and contents of routine antenatal care in remote rural China in 2009-2016: An observational study.

OBJECTIVE: We assessed factors associated with the frequency and contents of antenatal care (ANC) in remote rural China, including the province of residence and individual-level factors. DESIGN: Survey-based cross-sectional study. SETTING: Five provinces in remote rural China: Guizhou, Hunan, Jilin, Ningxia and Shaanxi. SAMPLE: A cohort of 3918 women with a live birth in 2009-2016. METHODS: Poisson regression. MAIN OUTCOME MEASURES: ANC frequency: five or more visits, starting in the first trimester. ANC contents: coverage of six care components and overuse of ultrasound. RESULTS: Three-quarters (72.9%) of women had five or more ANC visits, starting in the first trimester; 68.8% received all six care components and 94.5% had three or more ultrasounds. Only 30.9% of women sought ANC from township hospitals, paying between $3.80 and $25.80 per visit. ANC frequency and contents were associated with the socio-economic characteristics of the women, but provincial effects were much greater, even after adjusting for individual factors. Women living in Guizhou and Ningxia, the two poorest provinces, with high proportions of ethnic minorities, were particularly underserved. Compared with women in Shaanxi, women in Guizhou were 33% (adjusted RR 0.67, 95% CI 0.61-0.74) less likely to receive five or more ANC visits, starting in the first trimester; women in Ningxia were 17% less likely (adjusted RR 0.83, 95% CI 0.76-0.90) to receive all six care components. CONCLUSIONS: The province of residence was a stronger predictor of ANC frequency and contents than the individual characteristics of women in China, suggesting that strengthening the decentralised system of the financing and organisation of ANC at the province level is crucial for achieving success. Future efforts are warranted to engage subregional administrations. TWEETABLE ABSTRACT: The province of residence was a stronger predictor of ANC frequency and contents than the individual characteristics of women.

A systematic review of the profile and density of the maternal and child health workforce in China.

BACKGROUND: To track progress in maternal and child health (MCH), understanding the health workforce is important. This study seeks to systematically review evidence on the profile and density of MCH workers in China. METHODS: We searched 6 English and 2 Chinese databases for studies published between 1 October 1949 and 20 July 2020. We included studies that reported on the level of education or the certification status of all the MCH workers in one or more health facilities and studies reporting the density of MCH workers per 100 000 population or per 1000 births. MCH workers were defined as those who provided MCH services in mainland China and had been trained formally or informally. RESULTS: Meta-analysis of 35 studies found that only two-thirds of obstetricians and paediatricians (67%, 95% CI: 59.6-74.3%) had a bachelor or higher degree. This proportion was lower in primary-level facilities (28% (1.5-53.9%)). For nurses involved in MCH care the proportions with a bachelor or higher degree were lower (20.0% (12.0-30.0%) in any health facility and 1% (0.0-5.0%) in primary care facilities). Based on 18 studies, the average density of MCH doctors and nurses was 11.8 (95% CI: 7.5-16.2) and 11.4 (7.6-15.2) per 100 000 population, respectively. The average density of obstetricians was 9.0 (7.9-10.2) per 1000 births and that of obstetric nurses 16.0 (14.8-17.2) per 1000 births. The density of MCH workers is much higher than what has been recommended internationally (three doctors and 20 midwives per 3600 births). CONCLUSIONS: Our review suggests that the high density of MCH workers in China is achieved through a mix of workers with high and low educational profiles. Many workers labelled as "obstetricians" or "paediatrician" have lower qualifications than expected. China compensates for these low educational levels through task-shifting, in-service training and supervision.

Excess mortality among patients with severe mental disorders and effects of community-based mental healthcare: a community-based prospective study in Sichuan, China.

BACKGROUND: High-quality primary care reduces premature mortality in the general population, but evidence for psychiatric patients in China is scarce. AIMS: To confirm excess mortality in patients with severe mental illness (SMI), and to examine the impact of community-based mental healthcare and other risk factors on their mortality. METHOD: We included 93 655 patients in 2012 and 100 706 in 2013 from the national mental health surveillance system in Sichuan, China to calculate the standardised mortality ratio (SMR). A total of 112 576 patients were followed up from 2009 to 2014 for model analyses. We used growth models to quantify the patterns of change for community management measures, high-risk behaviour, disease stability and medication adherence of patients over time, and then used multilevel proportional hazard models to examine the association between change patterns of management measures and mortality. RESULTS: The SMR was 6.44 (95% CI 4.94-8.26) in 2012 and 7.57 (95% CI 5.98-9.44) in 2013 among patients with SMI aged 15-34 years, and diminished with age. Unfavourable baseline socioeconomic status increased the hazard of death by 38-50%. Positive changes in high-risk behaviour, disease stability and medication adherence had a 54% (95% CI 47-60%), 69% (95% CI 63-73%) and 20% (4-33%) reduction in hazard of death, respectively, versus in those where these were unchanged. CONCLUSIONS: High excess mortality was confirmed among younger patients with SMI in Sichuan, China. Our findings on the relationships between community management and socioeconomic factors and mortality can inform community-based mental healthcare policies to reduce excess mortality among patients with SMI.

Abortion metrics: a scoping review of abortion measures and indicators.

Consensus is lacking on the most appropriate indicators to document progress in safe abortion at programmatic and country level. We conducted a scoping review to provide an extensive summary of abortion indicators used over 10 years (2008-2018) to inform the debate on how progress in the provision and access to abortion care can be best captured. Documents were identified in PubMed and Popline and supplemented by materials identified on major non-governmental organisation websites. We screened 1999 abstracts and seven additional relevant documents. Ultimately, we extracted information on 792 indicators from 142 documents. Using a conceptual framework developed inductively, we grouped indicators into seven domains (social and policy context, abortion access and availability, abortion prevalence and incidence, abortion care, abortion outcomes, abortion impact and characteristics of women) and 40 subdomains. Indicators of access and availability and of the provision of abortion care were the most common. Indicators of outcomes were fewer and focused on physical health, with few measures of psychological well-being and no measures of quality of life or functioning. Similarly, there were few indicators attempting to measure the context, including beliefs and social attitudes at the population level. Most indicators used special studies either in facilities or at population level. The list of indicators (in online supplemental appendix) is an extensive resource for the design of monitoring and evaluation plans of abortion programmes. The large number indicators, many specific to one source only and with similar concepts measured in a multitude of ways, suggest the need for standardisation.

Socio-demographic factors of cesarean births in Nha Trang city, Vietnam: a community-based survey.

BACKGROUND: The cesarean section rate in Vietnam has been increasing especially in urban area. However, limited evidence identified regarding socio-demographic factors of the cesarean section birth. The objective of this study was to determine the current cesarean birth rate and the associated socio-demographic factors among mothers in Nha Trang city, south-central Vietnam. METHODS: A community-based cross-sectional study was conducted between October and November in 2016 as part of a Streptococcus pneumoniae carriage survey conducted in 27 communes of Nha Trang city. From each commune, 120 mothers and their children less than 2 years old were randomly selected. Mothers were asked to answer standardized questions regarding socio-demographic information and mode of birth. Multivariate logistic regression was adopted to examine associations between socio-demographic variables and mode of birth. RESULTS: Of 3148 participants, the number of cesarean births was 1396 (44.3 %). Older maternal age (≥ 30 years old), having another child going to school or kindergarten, monthly income more than 644 USD, gestational weeks at birth over 42 weeks, and low (< 2500 g) or high (≥ 3500 g) birth weight were associated with higher likelihood of cesarean births. CONCLUSION: The CS rate obtained in this study was more than twice of what is recommended by the World Health Organization, which is consistent with the previous nation-wide study in Viet Nam. Further monitoring is suggested to examine the non-medical reason for the increased CS rate.

Direct maternal deaths attributable to HIV in the era of antiretroviral therapy: evidence from three population-based HIV cohorts with verbal autopsy.

OBJECTIVE: To assess whether HIV is associated with an increased risk of mortality from direct maternal complications. DESIGN: Population-based cohort study using data from three demographic surveillance sites in Eastern and Southern Africa. METHODS: We use verbal autopsy data, with cause of death assigned using the InSilicoVA algorithm, to describe the association between HIV and direct maternal deaths amongst women aged 20-49 years. We report direct maternal mortality rates by HIV status, and crude and adjusted rate ratios comparing HIV-infected and uninfected women, by study site and by ART availability. We pool the study-specific rate ratios using random-effects meta-analysis. RESULTS: There was strong evidence that HIV increased the rate of direct maternal mortality across all the study sites in the period ART was widely available, with the rate ratios varying from 4.5 in Karonga, Malawi [95% confidence interval (CI) 1.6-12.6] to 5.2 in Kisesa, Tanzania (95% CI 1.7-16.1) and 5.9 in uMkhanyakude, South Africa (95% CI 2.3-15.2) after adjusting for sociodemographic confounders. Combining these adjusted results across the study sites, we estimated that HIV-infected women have 5.2 times the rate of direct maternal mortality compared with HIV-uninfected women (95% CI 2.9-9.5). CONCLUSION: HIV-infected women face higher rates of mortality from direct maternal causes, which suggests that we need to improve access to quality maternity care for these women. These findings also have implications for the surveillance of HIV/AIDS-related mortality, as not all excess mortality attributable to HIV will be explicitly attributed to HIV/AIDS on the basis of a verbal autopsy interview.

Does women's age matter in the SDGs era: coverage of demand for family planning satisfied with modern methods and institutional delivery in 91 low- and middle-income countries.

BACKGROUND: The Sustainable Development Goals (SDGs) include specific targets for family planning (SDG 3.7) and birth attendance (SDG 3.1.2), and require analyses disaggregated by age and other dimensions of inequality (SDG 17.18). We aimed to describe coverage with demand for family planning satisfied with modern methods (DFPSm) and institutional delivery in low- and middle-income countries across the reproductive age spectrum. We attempted to identify a typology of patterns of coverage by age and compare their distribution according to geographic regions, World Bank income groups and intervention coverage levels. METHODS: We used Demographic and Health Survey and Multiple Indicator Cluster Surveys. For DFPSm, we considered the woman's age at the time of the survey, whereas for institutional delivery we considered the woman's age at birth of the child. Both age variables were categorized into seven groups of 5 year-intervals, 15-19 up to 45-49. Five distinct patterns were identified: (a) increasing coverage with age; (b) similar coverage in all age groups; (c) U-shaped; (d) inverse U-shaped; and (e) declining coverage with age. The frequency of the five patterns was examined according to UNICEF regions, World Bank income groups, and coverage at national level of the given indicator. RESULTS: We analyzed 91 countries. For DFPSm, the most frequent age patterns were inverse U-shaped (53%, 47 countries) and increasing coverage with age (41%, 36 countries). Inverse-U shaped patterns for DFPSm was the commonest pattern among lower-middle income countries, while low- and upper middle-income countries showed a more balanced distribution between increasing with age and U-shaped patterns. In the first and second tertiles of national coverage of DFPSm, inverse U-shaped was observed in more than half of countries. For institutional delivery, declining coverage with age was the prevailing pattern (44%, 39 countries), followed by similar coverage across age groups (39%, 35 countries). Most (79%) upper-middle income countries showed no variation by age group while most low-income countries showed declining coverage with age (71%). CONCLUSION: Large inequalities in DFPSm and institutional delivery were identified by age, varying from one intervention to the other. Policy and programmatic approaches must be tailored to national patterns, and in most cases older women and adolescents will require special attention due to lower coverage and because they are at higher risk for maternal mortality and other poor obstetrical outcomes.

What the percentage of births in facilities does not measure: readiness for emergency obstetric care and referral in Senegal.

Introduction: Increases in facility deliveries in sub-Saharan Africa have not yielded expected declines in maternal mortality, raising concerns about the quality of care provided in facilities. The readiness of facilities at different health system levels to provide both emergency obstetric and newborn care (EmONC) as well as referral is unknown. We describe this combined readiness by facility level and region in Senegal. Methods: For this cross-sectional study, we used data from nine Demographic and Health Surveys between 1992 and 2017 in Senegal to describe trends in location of births over time. We used data from the 2017 Service Provision Assessment to describe EmONC and emergency referral readiness across facility levels in the public system, where 94% of facility births occur. A national global positioning system facility census was used to map access from lower-level facilities to the nearest facility performing caesareans. Results: Births in facilities increased from 47% in 1992 to 80% in 2016, driven by births in lower-level health posts, where half of facility births now occur. Caesarean rates in rural areas more than doubled but only to 3.7%, indicating minor improvements in EmONC access. Only 9% of health posts had full readiness for basic EmONC, and 62% had adequate referral readiness (vehicle on-site or telephone and vehicle access elsewhere). Although public facilities accounted for three-quarters of all births in 2016, only 16% of such births occurred in facilities able to provide adequate combined readiness for EmONC and referral. Conclusions: Our findings imply that many lower-level public facilities-the most common place of birth in Senegal-are unable to treat or refer women with obstetric complications, especially in rural areas. In light of rising lower-level facility births in Senegal and elsewhere, improvements in EmONC and referral readiness are urgently needed to accelerate reductions in maternal and perinatal mortality.

Testing the assumptions of an indicator of unmet need for obstetric surgery in Ghana: A cross-sectional study of linked hospital and population-based delivery data.

BACKGROUND: The Unmet Obstetric Need (UON) indicator has been widely used to estimate unmet need for life-saving surgery at birth; however, its assumptions have not been verified. The objective of this study was to test two UON assumptions: (a) Absolute maternal indications (AMIs) require surgery for survival and (b) 1%-2% of deliveries develop AMIs, implying that rates of surgeries for AMIs below this threshold indicate excess mortality from these complications. METHODS: We used linked hospital and population-based data in central Ghana. Among hospital deliveries, we calculated the percentage of deliveries with AMIs who received surgery, and mortality among AMIs who did not. At the population level, we assessed whether the percentage of deliveries with surgeries for AMIs was inversely associated with mortality from these complications, stratified by education. RESULTS: A total of 380 of 387 (98%) hospital deliveries with recorded AMIs received surgery; an additional eight women with no AMI diagnosis died of AMI-related causes. Among the 50 148 deliveries in the population, surgeries for AMIs increased from 0.6% among women with no education to 1.9% among women with post-secondary education (P < .001). However, there was no association between AMI-related mortality and education (P = .546). Estimated AMI prevalence was 0.84% (95% CI: 0.76%-0.92%), below the assumed 1% minimum threshold. DISCUSSION: Obstetric providers consider AMIs absolute indications for surgery. However, low rates of surgeries for AMIs among less educated women were not associated with higher mortality. The UON indicator should be used with caution in estimating the unmet need for life-saving obstetric surgery; innovative approaches are needed to identify unmet need in the context of rising cesarean rates.

Uptake of maternal care and childhood immunization among ethnic minority and Han populations in Sichuan province: a study based on the 2003, 2008 and 2013 health service surveys.

BACKGROUND: China has made remarkable progress in maternal and child health (MCH) over the last thirty years, but socio-economic inequalities persist. Ethnicity has become an important determinant of poor MCH outcomes, but little rigorous analytical work has been done in this area. To understand the socio-economic factors that explain ethnic variation in uptake of MCH care, we report the findings from an analysis in Sichuan province. METHODS: We linked data from the 2003, 2008 and 2013 National Health Service Surveys in Sichuan Province. The ethnic disparities in uptake of maternal care (completing 5 antenatal visits, giving birth in hospital and receiving a caesarean section) and childhood immunization (Bacillus Calmette Guerin (BCG), three doses of diphtheria (DPT) and measles immunization) were examined by geographical (Han district/county vs. ethnic minority county) and individual-based (Han women/children vs. ethnic minority women/children) comparisons. We also examined variation by distance to township and county hospitals, women's education, parity and age using weighted multilevel Poisson regressions with random intercept at district/county level. RESULTS: Ethnic inequalities in maternal care were marked, both at the geographical (district/county) and the individual level. The % of births in hospital was 90.7% among women in Han districts, compared to 83.3% among women living in Han counties (crude RR 0.93; 95% CI 0.75-1.15), 53.8% among Han women living in ethnic minority counties (crude RR 0.57; 95% CI 0.36-0.93), and 13.5% among ethnic minority women living in ethnic minority counties (crude RR 0.18; 95% CI 0.06-0.57). Adjusting the analysis for survey year, education, parity and distance to county level hospital weakened the association between geographical/individual ethnicity and uptake of maternity care, but associations remained remarkably strong. Coverage of childhood immunization was much higher than uptake of maternity care, and inequalities by ethnicity were much less pronounced. CONCLUSION: Lessons can be learned from China's successful immunization programme to further reduce inequalities in access to maternity care among ethnic minority populations in remote areas. Bringing the services closer to the women's homes and strengthening health promotion from the township to the village level may encourage more women to seek antenatal care and give birth in hospital.
