Background: The Universal Periodic Review (UPR) is a peer-review mechanism established to hold UN Member States accountable for human rights including the right to health, yet evidence on its impact on health outcomes is limited. We evaluated whether UPR engagement is associated with accelerated improvements in maternal health trajectories. Methods and Findings: We conducted a longitudinal ecological analysis of 89 countries with a baseline maternal mortality ratio (MMR) of 70 or greater per 100,000 live births in 2005. Outcomes were trajectories of annual MMR, skilled birth attendance (SBA), and contraceptive prevalence rate (CPR), from 2005 to 2023. The exposure was the volume of health-related UPR recommendations received across three cycles, thematically classified using a validated rule-based algorithm. Mixed-effects models adjusted for time-varying GDP per capita and historical fragility. The 89 countries received 41,733 UPR recommendations across three cycles, of which 405 (1%) were related to maternal health. Maternal health recommendations were preferentially directed at countries with higher baseline MMR and lower SBA. After adjustment, each additional maternal health recommendation was associated with a 0.24% [95% confidence interval (CI): 0.08, 0.40] faster annual reduction in MMR, a 0.52% [0.12, 0.91] faster annual gain in the odds of SBA, and a 0.21% [0.09, 0.34] faster annual gain in the odds of CPR. Broader recommendations on women's health and health systems and services were also associated with faster annual improvements in trajectories across all three outcomes; recommendations on abortion, family planning, sexual health and wellbeing, and sexual education tended to be directed towards lower-burden countries and were not associated with differences in any trajectories. It is important to note that the ecological design precludes causal inference. Conclusions: Receiving UPR recommendations on the themes of maternal health, womens health, and health systems and services are associated with accelerated improvements in maternal health trajectories among high-burden countries. These findings suggest that international human rights accountability mechanisms may have a role in supporting national progress on maternal health.

Background In the Democratic Republic of the Congo (DRC), health care financing relies heavily on out-of-pocket payments, limiting access to essential services. In a context of declining external funding and ongoing efforts toward Universal Health Coverage (UHC), understanding households willingness to pay (WTP) for health care is critical for designing sustainable financing strategies. This study aimed to assess WTP for primary health care services and identify its associated factors in Eastern Kasai Province. Methods A cross-sectional study based on the contingent valuation method was conducted from 10 to 30 July 2025 among 633 randomly selected households using a multistage probabilistic sampling approach. Data were collected through semi-structured interviews using KoboToolBox. WTP was assessed using a stated preference approach. Logistic regression analyses using R 4.5.0 were performed to identify factors associated with WTP at a significance level of p < 0.05. Adjusted odds ratios (aORs) with 95% confidence intervals (95% CI) were reported. Results Overall, 70% of household heads reported willingness to pay for their own health care, and 73% for other household members. WTP decreased significantly as the cost of services increased, dropping from 95.5% for free care to 6.3% at the highest cost levels (above CDF 230,000). Poor perceived quality of care was a consistent reason for refusal, alongside financial constraints such as low income and indebtedness. Multivariable analysis showed that having a professional activity (OR = 1.9; 95% CI: 1.2-3.0; p = 0.006), residence in rural areas (OR = 2.1; 95% CI: 1.3-3.7; p = 0.008), and higher household income (OR = 2.2; 95% CI: 1.2-4.0; p = 0.011) were significantly associated with WTP. Despite relatively low absolute health care costs, the majority of households perceived them as high. Conclusion Willingness to pay for health care services in Eastern Kasai is moderate but highly sensitive to cost and strongly influenced by socioeconomic conditions and perceived quality of care. These findings underscore the need to strengthen financial protection mechanisms, particularly prepayment and risk-pooling systems, while improving service quality to enhance health care utilization and progress toward UHC in the DRC.

Background Large-for-gestational-age (LGA) and macrosomic newborns are at increased risk of adverse perinatal outcomes, including death, yet the burden of neonatal mortality associated with these conditions in low- and middle-income countries (LMICs), where ongoing nutritional and epidemiological transitions suggest their prevalence will rise, remains poorly quantified. In this study, we quantify the neonatal mortality risk associated with LGA and macrosomia from 16 subnational birth cohorts in low- and middle-income countries between 2000 and 2017. Methods and findings This is an individual-participant meta-analysis to estimate neonatal mortality rates (NMRs) and relative risks among LGA infants (>90th and >97th percentile birth weight-for-gestational-age using INTERGROWTH-21st) versus appropriate-for-gestational-age (AGA, 10th-90th percentile) infants. Macrosomic ([&ge;]4000 g and [&ge;]4500 g) neonates were compared with those weighing 2500 g-3999g. Missing birth weights were imputed using recalibration and multiple imputation methods. We used random effects meta-analysis to pool relative risks. Median prevalences of LGA >90th and >97th percentile were 5.3% (interquartile range 3.6-8.2) and 2.6% (IQR 1.3-4.5), respectively; macrosomia ([&ge;]4000 g and [&ge;]4500 g) prevalences were 1.0% (IQR 0.3-3.1) and 0.06% (IQR 0.0, 0.30), respectively. Mortality was highest among preterm plus LGA infants (61.3 per 1000). LGA infants in the >90th percentile had over twofold increased mortality compared with appropriate-for-gestational-age infants (RR: 2.46; 95% CI: 1.86-3.25), while >97th percentile infants had a higher risk (RR: 3.77; 95% CI: 2.50-5.69). Term LGA >97th percentile infants also showed elevated mortality (RR: 3.14; 95% CI: 1.58-6.22). For LGA >97th percentile, the risk was higher in the early neonatal period (RR: 2.71; 95% CI: 1.92-3.82) than late (RR: 1.69; 95% CI: 1.22-2.34). There was no overall association between macrosomia ([&ge;]4000 g) and neonatal mortality. Population attributable fractions were 7.2% for LGA >90th percentile and 0.4% for macrosomia ([&ge;]4000 g). Conclusions Neonatal mortality risks were elevated among LGA infants in low- and middle-income countries, particularly at extreme values (>97th percentile) and during the early neonatal period. Macrosomia showed weaker, less robust associations. Although LGA prevalence is currently low ([~]5%) and contributes less to neonatal mortality than small newborns, ongoing nutritional and epidemiological transitions suggest increasing prevalence. This highlights the need for strengthened surveillance, monitoring, and improved delivery planning to ensure that no population is left behind.

Background: The traditional wealth index, based on principal component analysis (PCA), used in the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS), suffers from urban bias, distorting estimates of health inequality. We compared the traditional index (PEAR1) with an alternative two-component polychoric PCA index (POLY2) using annual expenditure from 12 LSMS surveys as the gold standard to determine which provides more accurate SEP measures for equitable policy targeting. Methods: We compared the traditional wealth index (PEAR1) with a two-component polychoric PCA approach (POLY2) using 12 LSMS (Living Standards Measurement Study) surveys (2015-2022) from 12 African countries. Annual household consumption expenditure was the gold standard. We assessed agreement using weighted Cohen's kappa and validated against education (proportion of households with secondary or higher education) using the concentration index (CIX) and slope index of inequality (SII). Results: The POLY2 index showed higher agreement with expenditure quintiles (average national weighted kappa = 43.3%) than the PEAR1 index (35.1%), with notable improvements in urban (43.5% vs. 27.5%) and rural (35.3% vs. 22.4%) areas. POLY2 also attenuated extreme household distributions observed in PEAR1. Education validation showed that POLY2 produced intermediate inequality gradients between the flatter expenditure-based gradient and the steeper PEAR1-based gradient. Conclusion: The POLY2 wealth index is superior to the traditional index, reducing urban-rural bias and providing more accurate socioeconomic classifications. Its adoption in large-scale surveys such as DHS and MICS is recommended to improve equitable monitoring of health inequalities in low- and middle-income countries.

Introduction: Induction of labour is a widely used obstetric intervention, yet its use varies markedly, with underuse in some settings and increasing elective use in others. However, the global prevalence and trends worldwide is unknown. We aimed to synthesise national and subnational data to estimate the prevalence of labour induction internationally and assess trends over time. Methods: We sought data from 194 countries through a structured search of national databases and relevant websites. For countries lacking adequate national data, we conducted a systematic review of published studies. Eligible data were pooled to estimate the prevalence of labour induction for 2019, and to examine temporal trends from 2010 to 2022. We used mixed-effects negative binomial regression models with missing data handled using multiple imputation by chained equations. Results: Data were obtained for 62 countries, including national-level data from 19 countries and 176 studies from 43 countries. Overall, 40 countries contributed to the 2019 estimate and 43 to the trend analysis. Most countries with data were high-income (N=37, 86.0%) and in Europe (N=29, 67.4%); there were no eligible data for sub-Saharan Africa. The estimated rate of labour induction for 2019 was 23.7% (95% confidence interval (CI): 19.3% to 29.2%). Induction had an estimated annual increase of 4% between 2010 and 2022 (incidence rate ratio 1.04, 95% CI 1.02 to 1.06). Conclusion: This study provides the first international estimates of labour induction, revealing high and rising rates globally. These trends likely reflect expanded clinical indications and improved access, but also signal potential overuse in resource-rich contexts. Our findings highlight a critical data gap in LMICs, particularly in Sub-Saharan Africa. Strengthening national perinatal data systems, especially in these settings, is essential for monitoring and guiding appropriate use. Identifying the optimal induction rate should be a priority for future research and clinical practice.

Objectives and study: This study aimed to examine predictors of post-partum maternal mental health (MMH) and coping during COVID-19 lockdown across seven countries (the UK, China, Japan, Malaysia, Mexico, Argentina, and Thailand). Methods: An anonymous questionnaire, developed in the UK in English and translated into local languages, was used in 2021-2022 to collect data on MMH and perceived coping ability from women aged [&ge;]18 years with an infant born before or during lockdowns. Five MMH components (worry, sadness, loneliness, difficulty relaxing, annoyance) and coping were assessed on a 4-point Likert scale, then dichotomised. MMH and coping were compared across countries using Chi-square tests with post-hoc pairwise comparisons conducted via Bonferroni-adjusted z-tests. Predictors of MMH and coping were examined using multivariable logistic regression. Results: A total of 7,650 women were analysed. Younger infant age, higher income, walking and exercise, and level of support were associated with better MMH and coping, whereas higher education was associated with better coping but poorer MMH. MMH and coping differed across countries (all p<0.001), which remained after adjusting for covariates: mothers in Asian countries reported better MMH, while those in the UK and Thailand reported better coping. Conclusions: Postpartum MMH and coping during lockdown were shaped by both individual and contextual factors. Findings highlight cross-country differences and underscore the need to strengthen maternal support system during future disruptions to perinatal care.

Abstract Objective: This study aimed to assess the magnitude of undernutrition and associated factors among pregnant women attending public health facilities in the Goba district, Bale zone, Oromia Region, Ethiopia, 2022. Design: Institution-based, cross-sectional study design was used. Setting: The study was conducted in selected public health facilities from May to June 2022. Participants: The study population consisted of pregnant women who lived for at least 6 months in the study area and who attended antenatal care follow-up at selected public health facilities during the study period. Pregnant women who lived for less than six months in the study area and those who were critically ill were excluded from the study. Results: 487 respondents participated in this study with a 100% response rate. More than half (50.7%) of pregnant mothers were undernourished. The significant factors associated with maternal undernutrition during pregnancy in this study were mothers with no formal education (AOR = 5.050; 95% CI: 1.470- 17.346), a history of illness during pregnancy (AOR = 2.089; 95% CI: 1.246-3.504), and eating frequency of meals less than or equal to three times per day (AOR = 3.292; 95% CI: 1.040- 10.42). Poor nutritional knowledge (AOR = 5.588; 95% CI: 2.921-10.689), poor household (HH) wealth status (AOR = 4.774; 95% CI: 2.216- 10.285), and mothers who had >= 4 pregnancies were included (AOR = 0.852; 95% CI: 342-0.989). Conclusion: The magnitude of Undernutrition among pregnant women was 50.7%. Significant associations with Undernutrition were found in mothers with no formal education, poor dietary knowledge, a meal frequency of three or fewer times per day, a history of illness during pregnancy, lower and medium household wealth status, and those who had experienced four or more pregnancies while attending antenatal care (ANC) services at public health facilities.

Background Chinas rapidly ageing population has increased the demand for long-term care insurance (LTCI), while the sustainability of current financing arrangements remains uncertain. Understanding willingness to pay (WTP) for improved LTCI services among LTCI beneficiaries or primary family caregivers may provide empirical evidence for discussions on acceptable and sustainable contribution mechanisms. Methods We conducted a contingent valuation survey among 278 LTCI beneficiaries or primary family caregivers in Panjin City, Liaoning Province, China. An iterative bidding game with randomized starting bids was used to elicit monthly WTP for a predefined LTCI service improvement scenario. Tobit regression models with heteroskedasticity-robust standard errors were used to estimate factors associated with WTP, including household income, disability severity, satisfaction with current services, and demographic characteristics. Results The mean monthly WTP for improved LTCI services was approximately CNY 300, compared with the current average monthly premium of approximately CNY 120. The median WTP was CNY 250. Higher household income was positively associated with WTP. Compared with participants with monthly household income below CNY 5,000, those in the highest income group above CNY 30,000 reported an additional WTP of CNY 178.9. More severe disability was also associated with higher WTP, whereas greater satisfaction with current LTCI services was associated with lower WTP. These associations were generally consistent across alternative model specifications. Conclusions LTCI beneficiaries or primary family caregivers in this Chinese pilot city reported a willingness to contribute more for improved LTCI services, particularly among those with higher income, greater care needs, or lower satisfaction with current services. These findings may inform discussions on differentiated contribution arrangements and service quality improvements in LTCI financing reform. However, the results should be interpreted cautiously because the study was conducted in a single pilot city and relied on stated-preference data.

Background: Maternal micronutrient deficiencies (MNDs) and inflammation contribute to adverse birth outcomes While the individual effects of MNDs have been studied, the consequence of co-occurring MNDs remains unclear. Objectives: To examine the associations between maternal micronutrient deficiencies and inflammation with adverse birth outcomes (ABOs). Methods: Data from 5,408 pregnant women across 11 datasets from 10 countries were analyzed. Descriptive analyses explored the distribution of MNDs (iron, vitamin A, zinc, serum folate, vitamin D, and vitamin B12) and inflammation (c-reactive protein >5 mg/L or -(1)-acid glycoprotein > 1g/L) by maternal characteristics (age, height, education, socioeconomic status [SES]) using chi-square tests. Associations of 1) single MNDs and inflammation and 2) co-occurring MNDs (2 deficiencies at a time) with low birth weight (LBW, < 2500 g), preterm birth (PTB, < 37 wks), and small-for-gestational age (SGA, < 10th percentile for gestational age), were examined using modified Poisson regression to estimate relative risk (RR), adjusting for age, SES, and dataset. Results: Young maternal age and short height were associated with up to 9.7% and 25% higher prevalence of MNDs and inflammation, respectively. Lower education and SES level were associated with higher prevalence of Vitamin B12 deficiency. Women with folate deficiency had an increased risk of LBW (RR [95% CI]: 1.22 [1.06, 1.39]). Co-occurring MNDs for folate and vitamin B12 were also associated with increased LBW risk (1.38 [1,1.9]) as was folate deficiency without iron (1.28 [1.09, 1.51]) or vitamin B12 deficiency (1.67 [1.09, 2.56]) compared with mothers without either deficiency. Iron deficiency without vitamin B12 deficiency was associated with a reduced LBW risk (0.4 [0.2, 0.79]). Conclusion: Maternal MNDs, especially folate and vitamin B12, are linked to adverse birth outcomes. Complex nutrient interactions highlight the need to explore these relationships to improve maternal and neonatal health interventions.

Background: The COVID-19 pandemic caused major disruptions to maternity care, breastfeeding support, and social networks. These changes may have increased the risk of postpartum depression, anxiety, and stress among breastfeeding mothers, a population that has been underrepresented in previous reviews. This systematic review and meta-analysis aimed to compare maternal mental health outcomes among breastfeeding mothers before and during the COVID-19 pandemic. Methods: We searched MEDLINE, EMBASE, AMED, Web of Science, WanFang Data, MedRxiv, WHO COVID-19 databases, and grey literature from database inception to December 2023. Eligible studies compared mental health outcomes in breastfeeding mothers before and during the COVID-19 pandemic using validated assessment tools, including the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder Scale (GAD-7), State-Trait Anxiety Inventory (STAI), or Perceived Stress Scale (PSS). Studies with fewer than 10 participants per group were excluded. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Joanna Briggs Institute checklist or Newcastle-Ottawa Scale, depending on study design. Random-effects meta-analysis was performed when at least two studies reported comparable outcomes. Results: Twenty-three studies involving breastfeeding mothers from 15 countries were included. Meta-analysis showed significantly higher depressive symptoms during the pandemic compared with the pre-pandemic period, measured by EPDS (standardized mean difference [SMD] = 0.21, 95% confidence interval [CI] 0.14 to 0.29). Maternal anxiety measured by GAD-7 was also significantly higher during the pandemic (SMD = 0.27, 95% CI 0.13 to 0.41). Findings for perceived stress were mixed across studies and could not be pooled because of heterogeneity in reporting methods. Limited evidence suggested that mother-infant bonding did not substantially decline during the pandemic despite increased maternal psychological distress. Conclusions: Breastfeeding mothers experienced increased postpartum depression and anxiety symptoms during the COVID-19 pandemic. These findings highlight the importance of maintaining breastfeeding support services, ensuring access to maternal mental health screening, and developing flexible models of postpartum care during future public health emergencies.

Background Appendicitis is a readily treatable surgical emergency, yet it remains a cause of preventable death among children in resource-limited settings. While recent studies have documented the global burden of pediatric appendicitis, none have systematically examined its geographic clustering or spatial spillover effects. Understanding whether high-mortality countries cluster geographically, and whether neighboring countries influence each other's outcomes, is essential for designing regional surgical capacity strategies. Methods We conducted a spatial analysis of pediatric appendicitis case fatality rates in children aged 0-14 years across 169 countries from 2000 to 2019. Data were obtained from the Global Burden of Disease Study 2023 and World Bank databases. We calculated global Moran's I to assess spatial autocorrelation, used Getis-Ord Gi* to identify local hotspots, and fitted spatial lag and spatial error regression models to quantify spatial spillovers while adjusting for GDP per capita, physician density, and basic sanitation access. Results Global Moran's I was 0.621 in 2000 (p < 0.001), 0.621 in 2010 (p < 0.001), and 0.592 in 2019 (p < 0.001), indicating strong and persistent spatial clustering. Hotspots at 99% confidence were consistently concentrated in sub-Saharan Africa and parts of South Asia, with little change in geographic distribution over two decades. The spatial error model provided the best fit (AIC = 212.6), with a spatial error coefficient ({lambda}) of 0.663 (p < 0.001), suggesting that approximately 66% of residual variation was explained by unobserved regional factors. In the final model, higher GDP per capita ({beta} = -0.497, p < 0.001) and higher physician density ({beta} = -0.568, p < 0.001) were independently associated with lower case fatality, while basic sanitation access showed no significant association (p = 0.284). Conclusions Pediatric appendicitis case fatality exhibits strong and persistent geographic clustering. The substantial spatial spillover effect suggests that regional coordination of surgical capacity building may be more effective than country-by-country investments. Priority should be given to hotspot countries in sub-Saharan Africa and South Asia, with emphasis on surgical workforce expansion rather than broad economic development alone.

Background/Objectives: Children aged 6-24 months are highly vulnerable to malnutrition during conflict because they depend on breastfeeding, complementary feeding and functioning nutrition services. This study assessed nutritional status, socioeconomic correlates, maternal knowledge and primary health care centre (PHCC) nutrition service gaps in Gaza. Subjects/Methods: This cross-sectional study was conducted at Al-Daraj Martyrs Health Centre, one of the remaining functioning PHCCs in Gaza City during the study period, between late August and October 2025. Mother-child pairs were recruited by convenience sampling. Of 276 approached, 200 were included after non-response and exclusion of questionnaires with missing anthropometric data. Data came from structured interviews and medical records; haemoglobin results were available for 55 children. Results: Stunting affected 12.5% of children, underweight 20.1%, wasting 20.8%, and anaemia 63.6% of the haemoglobin-tested subsample. Underweight was associated with household food shortage (p=0.013) and previous malnutrition treatment (p=0.002), wasting with child age category (p=0.0024), and anaemia with paternal unemployment (p=0.020). Maternal knowledge and practice scores were positively correlated (r=0.177, p=0.012), but neither was independently associated with stunting or underweight in adjusted models. PHCC nutrition support was limited, with 71.0% of mothers reporting nurse-provided nutrition advice and 52.5% reporting growth-chart review. Conclusions: In this clinic-based sample from conflict-affected Gaza, malnutrition among children aged 6-24 months was substantial. The overall pattern suggests that nutritional risk was shaped more by structural deprivation and weakened PHCC support than by maternal knowledge alone. These findings underline the need to restore essential nutrition services and improve access to adequate food for young children.

Introduction. Practice coaching is increasingly used to strengthen quality improvement (QI) capacity in primary healthcare (PHC) systems in low and middle income countries (LMICs), yet the causal pathways through which it shifts provider behaviour, and the systemic conditions that enable or constrain those pathways, remain under theorised. Using a theory based qualitative evaluation, we examined how and why a practice coaching intervention influenced QI in cervical cancer screening (CCS) and antenatal care (ANC) within Honduras decentralised PHC system during the third phase of the Salud Mesoamerica Initiative (SMI). Methods. We conducted a within case explanatory case study. A programme theory was reconstructed before data collection and iteratively refined against evidence. Data comprised semi structured interviews with 11 midlevel managers, 6 PHC team medical leads, and 2 regional managers, complemented by direct observation and document review. We applied combined deductive and inductive coding, thematic analysis, and pattern matching, and reporting per COREQ. Results. We identified four causal patterns that refined the initial programme theory. Three were activated pathways: (1) novel professional identity among participating managers; (2) collective efficacy and data driven learning, sustained through verifiable progress on observable indicators, strong for CCS but null for ANC, where outcomes were less attributable to teams actions; and (3) relational coordination, psychological safety, and trust, which provided the interpersonal basis for the first two. A fourth, unanticipated pattern showed structural misalignment between coaching enabling, learning based logic and the directive, punitive logic of Honduras performance based contracting environment, confining gains to localised enabling bubbles. Conclusion. Coaching can activate meaningful QI pathways in LMIC primary care, but sustained, equitable impact requires deliberate alignment between coaching learning oriented principles and the institutional performance management architecture, and matching of coaching investment to clinical processes with observable, attributable outcomes.

Introduction Access to quality early childhood development (ECD) services remains limited for families working in economic settings in many low-and middle-income countries. This study examined the associations between participation in integrated ECD centres of integrated ECD centres located in market and cross-border communities in Rwanda and childcare access, child nutrition, caregiving practices, and developmental outcomes. Methods A repeated cross-sectional pre-post evaluation without a comparison group was conducted between 2023 and 2025 across eight markets and cross-border ECD centres in Rwanda. Quantitative data were analyzed with logistic regression models adjusted for socio-demographic characteristics, while qualitative data were analysed thematically. University of Rwanda College of Medicine and Health Sciences Institution review board approved the study (No.366/CMHS IRB/2023). Results The proportion of children aged 6-23 months who achieved minimum meal frequency increased from 26.6% to 57% (AOR=2.35; 95% CI: 1.01-5.49), and those meeting minimum acceptable diet increased from 15.4% to 51.4% (AOR=4.51; 95% CI: 1.77-11.45). Stunting declined from 32.6% to 15.7% (AOR=0.45; 95% CI: 0.32-0.63) and underweight from 9.3% to 4.3% (AOR=0.55; 95% CI: 0.32-0.97). The proportion of children aged 24-59 months who were developmentally on track increased from 77.9% to 93.8% (AOR=3.85; 95% CI: 2.23-6.65). Households reported higher income at endline, and the centres generated strong demand for childcare services. However, reports of scolding and physical punishment increased between surveys. Conclusions Integrated ECD centres in market and cross-border settings were associated with improved child feeding practices, nutritional status, and developmental outcomes among children from vulnerable working families in Rwanda. Place-based childcare models may represent a promising strategy for expanding access to integrated ECD services while supporting womens economic participation in economic settings.

Background Malawis healthcare system faces strain due to an insufficient number of healthcare workers (HCWs). The number of HCWs currently employed falls below the Malawian governments own facility-based staffing standards, which are known as the establishment target. While vacancy rates from this target have been estimated, the health consequences of this workforce gap on the population have not. Methods This study quantifies the health-cost of unfilled establishment HCW positions using the Thanzi La Onse (TLO) model, an "all diseases - whole healthcare system" individual-based model, which self-consistently accounts for the dynamics between health system constraints and population health. We constructed two staffing scenarios: one (Current) in which the currently employed staff are represented, and another (Target) where all positions planned under the establishment target are filled. Using the TLO model, we then estimate the health impact of filling all establishment positions as the difference in the Disability-Adjusted Life Years (DALYs) incurred between the two scenarios. Results Our results indicate that fulfilling Target positions could reduce the health losses by 13.6% (43.1 million DALYs averted, 95% CI: 40.8-48.6) over the projection period. The largest proportional reductions are for DALYs caused by HIV/AIDS (41%), tuberculosis (26%), and malaria (24%) compared to the Current provision. Conclusions The analysis shows the potential health benefits associated with increasing the fulfilment of establishment positions in Malawi and offers key quantifications for policymakers as they strive to achieve Universal Health Coverage.

Introduction Perinatal Empowerment is widely referenced in maternity care research, yet its use often lacks clear conceptual definitions and validated measures. Existing instruments do not capture the multidimensional nature of perinatal empowerment, including both external dimensions (e.g., gender equity, resource access), and internal dimensions (e.g., confidence, agency and informed decision making). This gap has limited the ability to rigorously evaluate how healthcare experiences shape empowerment during pregnancy, birth, and the postpartum period. Aim To develop a valid and reliable instrument that measures dimensions of perinatal empowerment, both external and internal. Methods Instrument development followed the seven-step MEASURE framework. Initial item generation was guided by a concept analysis, a scoping review of existing instruments, and feedback from international midwifery experts. A preliminary 51-item instrument underwent expert content validity review, resulting in 48 items, which were then pilot-tested with six pregnant and postnatal women. A large-scale validation study was conducted via an international online survey (N=155). Psychometric testing included exploratory factor analysis (EFA), reliability assessment using Cronbachs , known-groups validity testing, and regression analyses adjusting for potential confounders. Results EFA supported two overarching dimensions--external and internal empowerment--with six factors across 30 final items (18 external, 12 internal). Sampling adequacy was high, and item loadings exceeded recommended thresholds. Internal consistency was strong for both dimensions (=0.88 external; =0.87 internal). Women receiving midwifery continuity of care reported significantly higher empowerment scores across total, external, and internal dimensions compared with other care models (p<.001). Differences between primiparous and multiparous women were not statistically significant. Conclusion The MPower instrument represents a conceptually grounded, psychometrically robust measure of multidimensional perinatal empowerment in high-income settings. Further validation in more diverse populations is needed to refine the instrument and expand its applicability across clinical and research contexts.

Exclusive breastfeeding (EBF) for the first six months is a critical protective practice, yet determinants beyond knowledge among young mothers in peri-urban sub-Saharan Africa remain insufficiently understood. This facility-based cross-sectional study assessed factors associated with EBF among 413 mothers aged 15-29 attending postnatal services at two public facilities in Lusaka, Zambia (Aug-Oct, 2025). Data from structured interviewer-administered questionnaires covered demographic, socioeconomic, cultural, mental health, peer support, and neonatal care knowledge factors. Logistic regression produced adjusted odds ratios (AOR) with 95% confidence intervals (CI). Although 99.5% reported receiving neonatal care education, 71.6% practiced EBF. Mothers aged 25-29 had lower odds of EBF than those aged 15-19 (AOR = 0.17, 95% CI: 0.03-0.99). Married mothers were more likely to exclusively breastfeed (AOR = 4.83, 95% CI: 1.59-14.65). Separated mothers also showed higher odds (AOR = 13.66, 95% CI: 1.89-98.71), although the wide confidence interval indicates substantial uncertainty and its based on a small subgroup (n=13). Formal employment was positively associated with EBF (AOR = 3.94, 95% CI: 1.12-13.85). Avoidance of specific traditional neonatal practices (AOR = 0.14, 95% CI: 0.04-0.53) and not consulting traditional healers (AOR = 0.06, 95% CI: 0.02-0.18) were also independently associated with EBF. Postnatal anxiety showed a strong inverse association (AOR = 0.14, 95% CI: 0.03-0.76). Parity, income, education, neonatal care awareness, and receipt of health education were not independently associated. These findings suggest that EBF in peri-urban Lusaka is shaped more by social, cultural, and psychological influences than knowledge alone, underscoring the need to integrate mental health screening, culturally sensitive counselling, and family-centred support within postnatal services to improve EBF uptake among young mothers in similar settings.

Background: Pregnancy loss has important implications for womens health. Although maternal age is a well-established risk factor, the contribution of routinely measured cardiometabolic and behavioral markers at population-scale remains incompletely characterized. Objective: To examine associations between cardiometabolic, nutritional, and behavioral risk markers and pregnancy loss among U.S. women of reproductive age. Methods: We conducted a cross-sectional analysis of 4,842 U.S. women aged 20-44 years with [&ge;]1 pregnancy using the National Health and Nutrition Examination Survey data (2013-2023). Pregnancy loss was defined as [&ge;]1 prior miscarriages. Exposures included body mass index, smoking exposure (cotinine), lipid biomarkers, vitamin D and folate, and a composite cardiometabolic-nutritional risk score. Survey-weighted logistic regression estimated adjusted odds ratios (aORs) and 95% confidence intervals, with bootstrap resampling for predictor robustness. Results: The weighted prevalence of pregnancy loss was 23%. Higher odds of pregnancy loss were associated with increasing age (aOR per year=1.02; 95% CI: 1.00-1.04), Non-Hispanic Black race (aOR=1.32; 95% CI: 1.00-1.74), overweight (aOR=1.56; 95% CI: 1.16-2.11), obesity (aOR=2.06; 95% CI: 1.39-3.05), and smoking (aOR=1.58; 95% CI: 1.19-2.10). Adverse lipid profiles, particularly elevated triglycerides (aOR=1.83; 95% CI: 1.16-2.90) and high low-density lipoprotein (aOR=2.97; 95% CI: 1.45-6.61), were independently associated with pregnancy loss. Vitamin D/folate were not stable predictors. Higher composite cardiometabolic-nutritional risk scores were observed among women with pregnancy loss (P=0.026). Conclusion: Pregnancy loss clustered with adverse cardiometabolic and behavioral risk markers in a nationally representative population. These findings highlight pregnancy loss as a marker of broader metabolic vulnerability supporting the need for longitudinal studies and cardiometabolic profiling to inform preconception care and risk stratification.

While significant progress has been made in perinatal outcomes over recent decades in low- and middle-income countries (LMICs), maternal and newborn quality improvement initiatives often fail to account for the spatial conditions in which they are implemented. Health systems are increasingly deploying evidence-based care models into built environments that are not optimally structured to meet the needs of its patient population. As the principal users, patients and health care workers can offer pragmatic insights about improving these structural designs. Our objective was to gather insights from patients, providers, and companions about how the physical design of their health facilities influenced their experience receiving or delivering perinatal care. We conducted a prospective observational study using a human-centred design (HCD) approach to analyse perceptions of the quality of perinatal care across two low resource settings: Ethiopia and Bangladesh. Using engagement and assessment tools, we conducted interviews, focus groups, facility walk-throughs, co-design workshops, and infrastructural assessments with patients, companions, providers, and Ministry of Health representatives. Descriptive statistics and thematic analysis were used to identify key learnings and develop recommendations. Across both countries, participants identified the need for facility layouts that better support privacy, mobility during labour, alternative birth positions, companion involvement, cultural and religious practices, sanitation, and provider visibility. Based on these insights, we developed six recommendations to better align health facility infrastructure with maternal and newborn care delivery needs. Our findings suggest that investments in health facility infrastructure may improve care experiences and help enable respectful, safe, and evidence-based maternal and newborn care. Alongside targeted spatial improvements, government authorities responsible for health facility planning should incorporate participatory design processes to ensure infrastructure reflects the needs of patients, companions, and providers and supports high-quality care delivery.

Background: Black patients and individuals with low socioeconomic status (SES) face significant disparities in accessing curative therapies for hepatocellular carcinoma (HCC), including liver transplantation. This study aimed to develop provider-co-created intervention prototypes in response to patient-identified barriers and recommendations. Methods: A human-centered design session with hepatology and transplant providers at a large academic medical center was conducted. Prior to the session, participants were presented with barriers and preliminary solutions identified through an earlier human-centered design session with Black and low-SES patients. Using structured ideation methods, including brainwriting, challenge mapping, and concept voting, providers co-created intervention prototypes. Final concepts were synthesized from patient insights, provider input, and design methods using affinity diagramming and concept modeling. Results: Nine providers participated in the session. They focused on three key areas for intervention: inefficiencies in transplant pre-evaluation, inadequate social support, and information overload. Solutions included: (1) a structured triage pathway to standardize referrals and reduce delays; (2) a peer navigator model to guide patients through the transplant process; and (3) a multimodal transplant education roadmap to improve comprehension and engagement. These prototypes addressed both patient- and system-level barriers. Conclusions: Protypes developed through provider-led design, grounded in patient-identified barriers and co-created ideas, can yield actionable, scalable strategies to advance equity in HCC care. Future work will refine these prototypes through patient feedback and pilot them in clinical settings.
