ABSTRACT

BACKGROUND: In Mexico, anemia prevalence among women of reproductive age (WRA) decreased from 16.4% in 2006 to 11.6% in 2012, only to increase to 18.3% in 2016. The factors associated with this fluctuation are uncertain. OBJECTIVE: We conducted a systematic in-depth assessment of the quantitative and qualitative determinants of anemia among WRA in Mexico between 2006 and 2018. METHODS: Using multivariate stepwise linear regression, we analyzed Mexico's Encuesta Nacional de Salud y Nutrición (ENSANUT) surveys from 2006, 2012, and 2018 to identify determinants of WRA anemia. We also conducted a review of anemia-relevant programs and policies, including financing documents, and conducted in-depth interviews and focus group discussions with key stakeholders in Mexico. RESULTS: Among non-pregnant women (NPW) 15-49 years, mean hemoglobin (Hb) increased from 13.8 g/dL in 2006 to 14.0 g/dL in 2012, decreasing to 13.2 g/dL in 2018 (p<0.001). Inequities by geographical region and household wealth persisted throughout this period, with household wealth, urban residence and gravidity emerging as significant predictors of Hb among NPW. Qualitative analyses generally supported these findings. The most discussed program was Progresa-Oportunidades-Prospera (POP), where most resources for health were invested and most participants acknowledged that its cancellation in 2019 would lead to worsening in health and nutrition among the poor. Financing analyses showed a drop of funding for nutrition-related programs between 2014 and 2018. Cultural norms around gender roles were still prevalent, along with increasing rates of teenage pregnancy. CONCLUSIONS: Anemia prevention efforts need to refocus on poverty alleviation, continuity of adequate coverage and financing of nutrition programs, especially with safety nets, and increase in uptake of family planning, especially among adolescent girls.

ABSTRACT

BACKGROUND: In Senegal, anemia prevalence among women of reproductive age (WRA) decreased from 59% in 2005 to 54% in 2017. However, determinants of reduction in disease burden under challenging public health conditions have not been studied. OBJECTIVE: To conduct a systematic in-depth assessment of the quantitative and qualitative determinants of anemia reduction among WRA in Senegal between 2005 and 2017. METHODS: Standard Exemplars in Global Health methodology was used for quantitative analyses using Senegal's Demographic and Health Surveys. Qualitative analyses included a systematic literature review, program/policy analysis, and interviews with key stakeholders. A final Oaxaca-Blinder decomposition analysis (OBDA) evaluated the relative contribution of direct and indirect factors. RESULTS: Among non-pregnant women (NPW), mean hemoglobin (Hb) increased from 11.4 g/dL in 2005 to 11.7 g/dL in 2017 (p<0.0001), corresponding to a 5%-point decline in anemia prevalence (58% to 53%). However, inequities by geographical region, household wealth, women's educational attainment, urban compared to rural residence, and antenatal care (ANC) during last pregnancy continue to persist. During this time period, several indirect nutrition programs were implemented, with stakeholders acknowledging the importance of these programs, but agreeing there needs to be more consistency, evaluation, and oversight for them to be effective. Our OBDA explained 59% of the observed change in mean Hb, with family planning (25%), malaria prevention programs (17%), use of iron and folic acid (IFA) during last pregnancy (17%), and improvement in women's empowerment (12%) emerging as drivers of anemia decline, corroborating our qualitative and policy analyses. CONCLUSIONS: Despite a reduction in anemia prevalence, anemia remains a severe public health problem in Senegal. To protect the gains achieved to date, as well as accelerate reduction in WRA anemia burden, focused efforts to reduce gender and social disparities, and improve coverage of health services, such as family planning, IFA, and antimalarial programs, are needed.

ABSTRACT

BACKGROUND: Anemia prevalence among women of reproductive age (WRA) in the Philippines was 25% in 2000, decreasing to 13% in 2018. To date, an in-depth assessment of the determinants associated with this decline has not been conducted. OBJECTIVE: To conduct a systematic in-depth assessment of the quantitative and qualitative determinants of anemia among WRA in the Philippines between 2008 and 2018. METHODS: Employing standard Exemplars methodology, we conducted quantitative analyses using the Philippines' National Nutrition Survey, the Expanded National Nutrition Survey, and the Philippines National Demographic and Health Surveys. Qualitative analyses included a comprehnsive literature review, program/policy analysis, and interviews with stakeholders to understand country-level enablers and barriers to WRA anemia decline in the Philippines. A final Oaxaca-Blinder decomposition analysis (OBDA) evaluated the relative contribution of direct and indirect factors. RESULTS: Among non-pregnant women (NPW), mean hemoglobin (Hb) increased from 12.7 g/dL in 2008 to 13.1 g/dL in 2018 (p<0.01), corresponding to an 11%-point decline in anemia prevalence (23% to 12%). Inequities by geographical region, household wealth, and women's educational attainment narrowed considerably during this time. Important direct and indirect nutrition programs were introduced during our study period, including universal healthcare and food fortification. Country experts interviewed credited programs focused on alleviating micronutrient deficiencies and poverty, and improvements in women's health and well-being, for the country's extraordinary success. OBDA explained ∼50% of the observed change in mean Hb among NPW, with family planning (35%), household socio-demographics (29%), and improvement in women's nutrition (23%) emerging as critical drivers of anemia decline, corroborating our qualitative and policy analyses. CONCLUSIONS: To protect these gains, WRA anemia prevention efforts in the Philippines should continue to focus on universal healthcare access, women's empowerment, and poverty alleviation.

ABSTRACT

Neonatal sepsis remains one of the key challenges of neonatal medicine, and together with preterm birth, causes almost 50% of all deaths globally for children younger than 5 years. Compared with advances achieved for other serious neonatal and early childhood conditions globally, progress in reducing neonatal sepsis has been much slower, especially in low-resource settings that have the highest burden of neonatal sepsis morbidity and mortality. By contrast to sepsis in older patients, there is no universally accepted neonatal sepsis definition. This poses substantial challenges in clinical practice, research, and health-care management, and has direct practical implications, such as diagnostic inconsistency, heterogeneous data collection and surveillance, and inappropriate treatment, health-resource allocation, and education. As the clinical manifestation of neonatal sepsis is frequently non-specific and the current diagnostic standard blood culture has performance limitations, new improved diagnostic techniques are required to guide appropriate and warranted antimicrobial treatment. Although antimicrobial therapy and supportive care continue as principal components of neonatal sepsis therapy, refining basic neonatal care to prevent sepsis through education and quality improvement initiatives remains paramount.

ABSTRACT

BACKGROUND: Since 2000, only a few countries have substantially reduced the burden of anemia among women 15-49 y of age. The exemplars in anemia reduction among women of reproductive age (WRA) studied the determinants of success among these countries. OBJECTIVES: To describe the methodology used to determine the factors associated with anemia reduction in high-performing countries, with the aim to guide policy and programmatic decisions in other countries with similar sociodemographic and health indices. METHODS: This article describes the process used to identify countries with exemplary reduction in WRA anemia burden, compared with their peers. We describe the exemplars in global health methodology, the mixed-methods approach used to identify and quantify the macro- and microlevel characteristics associated with anemia burden decline among WRA. Quantitative analyses include descriptive and equity analyses, multivariate linear regression, and Oaxaca-Blinder decomposition analysis. Qualitative analyses include in-depth interviews and focus group discussions with national, subnational, and community stakeholders, as well as review of programs and policies with the potential to impact women's health and/or nutrition, enacted in the countries over the last 20 y. A technical advisory group oversaw all research activities. RESULTS: We identified 5 countries, namely, Mexico, Pakistan, Philippines, Uganda, and Senegal, as anemia exemplars, after considering the magnitude of anemia decline between 2000 and 2018, availability of ≥2 nationally representative anemia surveys, geographical diversity to account for the complex etiology of anemia, regional representation, and logistics of in-country work. CONCLUSIONS: Exemplars in anemia reduction among WRA seeks to create awareness of how little anemia prevalence has changed globally and aims to inform and spur global efforts for improving women's health and nutrition.

ABSTRACT

Parasympathetic dysfunction after chronic myocardial infarction (MI) is known to predispose ventricular tachyarrhythmias (VT/VF). VT/VF after MI is more common in males than females. The mechanisms underlying the decreased vagal tone and the associated sex difference in the occurrence of VT/VF after MI remain elusive. In this study, using optogenetic approaches, we found that responses of glutamatergic vagal afferent neurons were impaired following chronic MI in male mice, leading to reduced reflex efferent parasympathetic function. Molecular analyses of vagal ganglia demonstrated reduced glutamate levels, accompanied by decreased mitochondrial function and impaired redox status in infarcted males vs. sham animals. Interestingly, infarcted females demonstrated reduced vagal sensory impairment, associated with greater vagal ganglia glutamate levels and decreased vagal mitochondrial dysfunction and oxidative stress compared to infarcted males. Treatment with 17ß-estradiol mitigated this pathological remodeling and improved vagal neurotransmission in infarcted male mice. These data suggest that a decrease in efferent vagal tone following MI results from reduced glutamatergic afferent vagal signaling that may be due to impaired redox homeostasis in the vagal ganglia, which subsequently leads to pathological remodeling in a sex-dependent manner. Importantly, estrogen prevents pathological remodeling and improves parasympathetic function following MI.

ABSTRACT

BACKGROUND: Zinc deficiency poses significant health risks, particularly in low-income settings. This study aims to evaluate the impact of agronomically zinc biofortified (fermented and non-fermented) and post-harvest wheat flour flatbread on zinc status and metabolic health in adolescents and adult women in rural Pakistan. METHODS: A four-arm triple-blind randomized controlled trial will be conducted in a rural district of Pakistan. Participants (adolescents aged 10-19 and adult women aged 20-40) will be assigned to receive fermented or unfermented high zinc agronomically biofortified wheat flour flatbread, post-harvest zinc-fortified wheat flour flatbread, or low zinc conventional whole wheat flour flatbread. The meal would be served once a day, six days a week for six months. The study aims to enroll 1000 participants and will be analyzed based on the intention-to-treat principle. The trial is registered with number NCT06092515. OUTCOMES: Primary outcomes will include serum zinc concentration and metabolic markers, while secondary outcomes include anthropometric measurements, blood pressure, and dietary intake. CONCLUSION: This trial will provide valuable insights into the efficacy of agronomically zinc biofortified wheat flour in improving zinc status and metabolic health. Findings may inform public health strategies to combat zinc deficiency in resource-limited settings.

ABSTRACT

CONTEXT: The school food environment is a critical interface for child and adolescent nutrition, and there is a need to understand existing literature on Canadian school food environments to identify equity gaps and opportunities, and empower decision-makers to plan for future action. OBJECTIVE: Literature on Canadian school food and nutrition interventions, policies, programs, and their effects on diets and nutritional status are synthesized and appraised in this systematic review. DATA SOURCES: A search strategy was developed for each database used (Medline, Embase, PsycINFO, ERIC, Cochrane Collaboration, Canadian Electronic Library, BiblioMap), with a combination of free text and controlled vocabulary, for articles published from 1990 to 2021. Unpublished data and grey literature were also searched. DATA EXTRACTION: Quantitative and qualitative studies with an observational or intervention study design, reviews, or program evaluations conducted in Canadian schools with participants aged 5-19.9 years were included. Key study characteristics and risk of bias were extracted independently by 2 investigators using a standardized tool. DATA ANALYSIS: A total of 298 articles were included (n = 192 peer reviewed and 106 from the grey literature), which were mostly conducted in Ontario (n = 52), British Columbia (n = 43), and Nova Scotia (n = 28). Twenty-four interventions, 5 nonevaluated programs, and 1 policy involved Indigenous populations. Overall, 86 articles measured and reported on effectiveness outcomes, including dietary intake; anthropometry; knowledge, attitudes, and practices; and physical activity. The literature remains largely heterogenous and primarily focused on nutrition education programs that use subjective assessments to infer changes in nutrition. A key facilitator to implementation and sustainability was community engagement, whereas key barriers were staff capacity, access to resources and funding, and consistent leadership. CONCLUSIONS: This review provides insight into Canadian school food and nutrition interventions, programs, and policies and uncovers important evidence gaps that require careful examination for future evaluations. Governments must create supportive environments that optimize nutrition for children and adolescents through equitable policies and programs. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42022303255.

ABSTRACT

Pakistan is one of two countries globally still endemic for poliovirus. While increasing immunization coverage is a concern, providing equitable access to care is also a priority, especially for conflict-affected populations. Recognizing these challenges, Naunehal, an integrated model of maternal, newborn, and child health (MNCH), immunization, and nutrition services delivered through community mobilization, mobile outreach, and private-sector engagement was implemented in conflict-affected union councils (UCs) with high poliovirus transmission, including Kharotabad 1(Quetta, Balochistan) and Bakhmal Ahmedzai (Lakki Marwat, Khyber Pakhtunkhwa). A quasi-experimental pre-post-design was used to assess the impact of the interventions implemented between April 2021 and April 2022, with a baseline and an endline survey. For each of the intervention UCs, a separate, matched-control UC was identified. At endline, the proportion of fully immunized children increased significantly from 27.5% to 51.0% in intervention UCs with a difference-in-difference (DiD) estimate of 13.6%. The proportion of zero-dose children and non-recipients of routine immunization (NR-RI) children decreased from 31.6% to 0.9% and from 31.9% to 3.4%, respectively, with a significant decrease in the latter group. Scaling up and assessing the adoption and feasibility of integrated interventions to improve immunization coverage can inform policymakers of the viability of such services in such contexts.

ABSTRACT

BACKGROUND: Public-private partnerships (PPP) are often how health improvement programs are implemented in low-and-middle-income countries (LMICs). We therefore aimed to systematically review the literature about the aim and impacts of quality improvement (QI) approaches in PPP in LMICs. METHODS: We searched SCOPUS and grey literature for studies published before March 2022. One reviewer screened abstracts and full-text studies for inclusion. The study characteristics, setting, design, outcomes, and lessons learned were abstracted using a standard tool and reviewed in detail by a second author. RESULTS: We identified 9,457 citations, of which 144 met the inclusion criteria and underwent full-text abstraction. We identified five key themes for successful QI projects in LMICs: 1) leadership support and alignment with overarching priorities, 2) local ownership and engagement of frontline teams, 3) shared authentic learning across teams, 4) resilience in managing external challenges, and 5) robust data and data visualization to track progress. We found great heterogeneity in QI tools, study designs, participants, and outcome measures. Most studies had diffuse aims and poor descriptions of the intervention components and their follow-up. Few papers formally reported on actual deployment of private-sector capital, and either provided insufficient information or did not follow the formal PPP model, which involves capital investment for a explicit return on investment. Few studies discussed the response to their findings and the organizational willingness to change. CONCLUSIONS: Many of the same factors that impact the success of QI in healthcare in high-income countries are relevant for PPP in LMICs. Vague descriptions of the structure and financial arrangements of the PPPs, and the roles of public and private entities made it difficult to draw meaningful conclusions about the impacts of the organizational governance on the outcomes of QI programs in LMICs. While we found many articles in the published literature on PPP-funded QI partnerships in LMICs, there is a dire need for research that more clearly describes the intervention details, implementation challenges, contextual factors, leadership and organizational structures. These details are needed to better align incentives to support the kinds of collaboration needed for guiding accountability in advancing global health. More ownership and power needs to be shifted to local leaders and researchers to improve research equity and sustainability.

ABSTRACT

OBJECTIVE: Monitoring trends in key population health indicators is important for informing health policies. The aim of this study was to examine population health trends in Canada over the past 30 years in relation to other countries. METHODS: We used data on disability-adjusted life years (DALYs), years of life lost (YLL), years lived with disability, life expectancy (LE), and child mortality for Canada and other countries between 1990 and 2019 provided by the Global Burden of Disease Study. RESULTS: Life expectancy, age-standardized YLL, and age-standardized DALYs all improved in Canada between 1990 and 2019, although the rate of improvement has leveled off since 2011. The top five causes of all-age DALYs in Canada in 2019 were neoplasms, cardiovascular diseases, musculoskeletal disorders, neurological disorders, and mental disorders. The greatest increases in all-age DALYs since 1990 were observed for substance use, diabetes and chronic kidney disease, and sense organ disorders. Age-standardized DALYs declined for most conditions, except for substance use, diabetes and chronic kidney disease, and musculoskeletal disorders, which increased by 94.6%, 14.6%, and 7.3% respectively since 1990. Canada's world ranking for age-standardized DALYs declined from 9th place in 1990 to 24th in 2019. CONCLUSION: Canadians are healthier today than in 1990, but progress has slowed in Canada in recent years in comparison with other high-income countries. The growing burden of substance abuse, diabetes/chronic kidney disease, and musculoskeletal diseases will require continued action to improve population health.


RéSUMé: OBJECTIF: La surveillance des tendances des indicateurs clés de la santé de la population est importante pour éclairer les politiques de santé. Dans cette étude, nous avons examiné les tendances de la santé de la population au Canada au cours des 30 dernières années par rapport à d'autres pays. MéTHODES: Nous avons utilisé des données sur les années de vie ajustées en fonction de l'incapacité (DALY), les années de vie perdues (YLL), les années vécues avec un handicap, l'espérance de vie (LE) et la mortalité infantile pour le Canada et d'autres pays entre 1990 et 2019, fournies par l'Étude mondiale sur le fardeau de la maladie. RéSULTATS: L'espérance de vie, les YLL ajustées selon l'âge et les DALY ajustées selon l'âge ont tous connu une amélioration au Canada entre 1990 et 2019, bien que le taux d'amélioration se soit stabilisé depuis 2011. Les cinq principales causes des DALY pour tous les âges au Canada en 2019 étaient les néoplasmes, les maladies cardiovasculaires, les affections musculosquelettiques, les affections neurologiques et les troubles mentaux. Les plus fortes augmentations des DALY pour tous les âges depuis 1990 ont été observées pour l'usage de substances, le diabète et les maladies rénales chroniques, ainsi que les troubles des organes sensoriels. Les DALY ajustées selon l'âge ont diminué pour la plupart des conditions, à l'exception de l'usage de substances, du diabète et des maladies rénales chroniques, ainsi que des troubles musculosquelettiques, qui ont augmenté de 94,6 %, 14,6 % et 7,3 % respectivement depuis 1990. Le classement mondial du Canada pour les DALY ajustées selon l'âge est diminué de la 9ième place en 1990 à la 24ième place en 2019. CONCLUSION: Les Canadiens sont en meilleure santé aujourd'hui qu'en 1990, mais les progrès se sont ralentis ces dernières années par rapport à d'autres pays à revenu élevé. La croissance du fardeau lié à l'abus de substances, au diabète/maladies rénales chroniques et aux affections musculosquelettiques exigera des actions continues pour améliorer la santé de la population.

ABSTRACT

Importance: In resource-constrained settings where the neonatal mortality rate (NMR) is high due to preventable causes and health systems are underused, community-based interventions can increase newborn survival by improving health care practices. Objectives: To develop and evaluate the effectiveness of a community-based maternal and newborn care services package to reduce perinatal and neonatal mortality in rural Pakistan. Design, Setting, and Participants: This cluster randomized clinical trial was conducted between November 1, 2012, and December 31, 2013, in district Rahim Yar Khan in the province of Punjab. A cluster was defined as an administrative union council. Any consenting pregnant resident of the study area, regardless of gestational age, was enrolled. An ongoing pregnancy surveillance system identified 12 529 and 12 333 pregnancies in the intervention and control clusters, respectively; 9410 pregnancies were excluded from analysis due to continuation of pregnancy at the end of the study, loss to follow-up, or miscarriage. Participants were followed up until the 40th postpartum day. Statistical analysis was performed from January to May 2014. Intervention: A maternal and newborn health pack, training for community- and facility-based health care professionals, and community mobilization through counseling and education sessions. Main Outcomes and Measures: The primary outcome was perinatal mortality, defined as stillbirths per 1000 births and neonatal death within 7 days per 1000 live births. The secondary outcome was neonatal mortality, defined as death within 28 days of life per 1000 live births. Systematic random sampling was used to allocate 10 clusters each to intervention and control groups. Analysis was conducted on a modified intention-to-treat basis. Results: For the control group vs the intervention group, the total number of households was 33 188 vs 34 315, the median number of households per cluster was 3092 (IQR, 3018-3467) vs 3469 (IQR, 3019-4075), the total population was 229 155 vs 234 674, the mean (SD) number of residents per household was 6.9 (9.5) vs 6.8 (9.6), the number of males per 100 females (ie, the sex ratio) was 104.2 vs 103.7, and the mean (SD) number of children younger than 5 years per household was 1.0 (4.2) vs 1.0 (4.3). Altogether, 7598 births from conrol clusters and 8017 births from intervention clusters were analyzed. There was no significant difference in perinatal mortality between the intervention and control clusters (rate ratio, 0.86; 95% CI, 0.69-1.08; P = .19). The NMR was lower among the intervention than the control clusters (39.2/1000 live births vs 52.2/1000 live births; rate ratio, 0.75; 95% CI, 0.58-0.95; P = .02). The frequencies of antenatal visits and facility births were similar between the 2 groups. However, clean delivery practices were higher among intervention clusters than control clusters (63.2% [2284 of 3616] vs 13.2% [455 of 3458]; P < .001). Chlorhexidine use was also more common among intervention clusters than control clusters (55.9% [4271 of 7642] vs 0.3% [19 of 7203]; P < .001). Conclusions and Relevance: This pragmatic cluster randomized clinical trial demonstrated a reduction in NMR that occurred in the background of improved household intrapartum and newborn care practices. However, the effect of the intervention on antenatal visits, facility births, and perinatal mortality rates was inconclusive, highlighting areas requiring further research. Nevertheless, the improvement in NMR underscores the effectiveness of community-based programs in low-resource settings. Trial Registration: ClinicalTrials.gov Identifier: NCT01751945.

ABSTRACT

Pakistan has among the highest rates of maternal, perinatal, and neonatal mortality globally. Many of these deaths are potentially preventable with low-cost, scalable interventions delivered through community-based health worker programs to the most remote communities. We conducted a cross-sectional survey of 10,264 households during the baseline phase of a cluster randomized controlled trial (cRCT) in Gilgit-Baltistan, Pakistan from June-August 2021. The survey was conducted through a stratified, two-stage sampling design with the objective of estimating the neonatal mortality rate (NMR) within the study catchment area, and informing implementation of the cRCT. Study outcomes were self-reported and included neonatal death, stillbirth, health facility delivery, maternal death, postpartum hemorrhage (PPH), and Lady Health Worker (LHW) coverage. Summary statistics (proportions and rates) were weighted according to the sampling design, and mixed-effects Poisson regression was conducted to explore the relationship between LHW coverage and maternal/newborn outcomes. We identified 7,600 women who gave birth in the past five years, among whom 13% reported experiencing PPH. The maternal mortality ratio was 225 maternal deaths per 100,000 live births (95% confidence interval [CI] 137-369). Among 12,376 total births, the stillbirth rate was 41.4 per 1,000 births (95% CI 36.8-46.7) and the perinatal mortality rate was 53.0 per 1,000 births (95% CI 47.6-59.0). Among 11,863 live births, NMR was 16.2 per 1,000 live births (95% CI 13.6-19.3) and 65% were delivered at a health facility. LHW home visits were associated with declines in PPH (risk ratio [RR] 0.89 per each additional visit, 95% CI 0.83-0.96) and late neonatal mortality (RR 0.80, 95% CI 0.67-0.97). Intracluster correlation coefficients were also estimated to inform the planning of future trials. The high rates of maternal, perinatal, and neonatal death in Gilgit-Baltistan continue to fall behind targets of the 2030 Sustainable Development Goals.

ABSTRACT

Through diverse roles, zinc determines a greater number of critical life functions than any other single micronutrient. Beyond the well-recognized importance of zinc for child growth and resistance to infections, zinc has numerous specific roles covering the regulation of glucose metabolism, and growing evidence links zinc deficiency with increased risk of diabetes and cardiometabolic disorders. Zinc nutriture is, thus, vitally important to health across the life course. Zinc deficiency is also one of the most common forms of micronutrient malnutrition globally. A clearer estimate of the burden of health disparity attributable to zinc deficiency in adulthood and later life emerges when accounting for its contribution to global elevated fasting blood glucose and related noncommunicable diseases (NCDs). Yet progress attenuating its prevalence has been limited due, in part, to the lack of sensitive and specific methods to assess human zinc status. This narrative review covers recent developments in our understanding of zinc's role in health, the impact of the changing climate and global context on zinc intake, novel functional biomarkers showing promise for monitoring population-level interventions, and solutions for improving population zinc intake. It aims to spur on implementation of evidence-based interventions for preventing and controlling zinc deficiency across the life course. Increasing zinc intake and combating global zinc deficiency requires context-specific strategies and a combination of complementary, evidence-based interventions, including supplementation, food fortification, and food and agricultural solutions such as biofortification, alongside efforts to improve zinc bioavailability. Enhancing dietary zinc content and bioavailability through zinc biofortification is an inclusive nutrition solution that can benefit the most vulnerable individuals and populations affected by inadequate diets to the greatest extent.

ABSTRACT

This study examines the impact of accredited social health activists (ASHAs), on increasing rates of institution-based deliveries among Indian women with a specific focus on the nine low-performing, empowered action group states and Assam (EAGA) in India. Using the latest round of the National Family Health Survey-V (2019-21), we first investigate the association between the use of ASHA services and socio-demographic attributes of women using a multivariate logistic regression. We then use propensity-score matching (PSM) to address observable selection bias in the data and assess the impact of ASHA services on the likelihood of institution-based deliveries using a generalized estimating equations model. Of the 232,920 women in our sample, 55.5% lived in EAGA states. Overall, 63.3% of women (70.6% in EAGA states) reported utilizing ASHA services, and 88.6% had an institution-based delivery (84.0% in EAGA states). Younger women from the poorest wealth index were more likely to use ASHA services and women in rural areas had a two-fold likelihood. Conversely, women with health insurance were less likely to use ASHA services compared to those without. Using PSM, the average treatment effect of using ASHA services on institution-based deliveries was 5.1% for all India (EAGA = 7.4%). The generalized estimating equations model indicated that the use of ASHA services significantly increased the likelihood of institution-based delivery by 1.6 times (95%CI = 1.5-1.7) for all India (EAGA = 1.8; 95%CI = 1.7-1.9). Our study finds that ASHAs are effective in enhancing the uptake of maternal services particularly institution-based deliveries. These findings underscore the necessity for continual, systematic investments to strengthen the ASHA program and to optimize the program's effectiveness in varied settings that rely on the community health worker model, thereby advancing child and maternal health outcomes.

ABSTRACT

Background: Preventive and promotive interventions delivered by schools can support a healthy lifestyle, positive development, and well-being in children and adolescents. The coronavirus disease 2019 (COVID-19) pandemic presented unique challenges to school health and nutrition programmes due to closures and mobility restrictions. Methods: We conducted a scoping review to examine how school health and nutrition programmes pivoted during the COVID-19 pandemic, and to provide summative guidance to stakeholders in strategic immediate and long-term response efforts. We searched MEDLINE, Embase, PsycINFO, and grey literature sources for primary (observational, intervention, and programme evaluations) and secondary (reviews, best practices, and recommendations) studies conducted in low- and middle-income countries from January 2020 to June 2023. Programmes that originated in schools, which included children and adolescents (5-19.9 years) were eligible. Results: We included 23 studies in this review. They varied in their adaptation strategy and key programmatic focus, including access to school meals (n = 8), health services, such as immunisations, eye health, and water, sanitation, and hygiene-related activities (n = 4), physical activity curriculum and exercise training (n = 3), mental health counselling and curriculum (n = 3), or were multi-component in nature (n = 5). While school meals, physical activity, and mental health programmes were adapted by out-of-school administration (either in the community, households, or virtually), all health services were suspended indefinitely. Importantly, there was an overwhelming lack of quantitative data regarding modified programme coverage, utilisation, and the impact on children and adolescent health and nutrition. Conclusions: We found limited evidence of successful adaptation of school health and nutrition programme implementation during the pandemic, especially from Asia and Africa. While the adoption of the World Health Organization health-promoting school global standards and indicators is necessary at the national and school level, future research must prioritise the development of a school-based comprehensive monitoring and evaluation framework to track key indicators related to both health and nutrition of school-aged children and adolescents.

ABSTRACT

BACKGROUND: The eradication of poliovirus and improving routine immunization (RI) coverage rates present significant challenges in Pakistan. There is a need for interventions that focus on strengthening community engagement to improve routine immunization coverage. Our primary objective is to assess the impact of an integrated strategy designed to enhance community engagement and maternal and child health immunization campaigns on immunization coverage in Pakistan's high-risk union councils of polio-endemic districts. METHOD: We implemented an integrated approach for routine immunization and maternal and child health in the polio-endemic district of Pakistan. This approach involved setting up health camps and actively engaging and mobilizing the local community. An independent team conducted surveys at three key points: baseline, midline, and endline, to evaluate immunization coverage among children under the age of five. The primary outcome measures for the study were coverage of OPV, IPV, and changes in the proportion of unvaccinated and fully vaccinated children. To select clusters and eligible households in each cluster, we utilized a 30 × 15 cluster sampling technique. Multivariable associations between socio-demographic factors and changes in the proportion of fully vaccinated children at the UC level were assessed using hierarchical linear regression models. RESULTS: A total of 256,946 children under the age of five (122,950 at baseline and 133,996 at endline) were enrolled in the study. By the endline, full immunization coverage had increased to 60% or more in all three study areas compared to the baseline. Additionally, there was a significant increase in the coverage of both OPV and IPV across all three provinces at the endline. The full immunization rates were assessed on three levels of the framework: the distal, intermediate (access and environment), and proximal level (camp attendance and effectiveness). At the distal level, on multivariate analysis, family size was found to be a significant predictor of change in immunity within the families (ß = 0.68; p ≤ 0.0001). At the intermediate level, the likelihood of full immunization decreased with the decrease in knowledge about vaccination (ß = -0.38; p = 0.002), knowledge about polio vaccine (ß = -0.25; p = 0.011), and knowledge about IPV (ß = -0.06; p = 0.546). Perceived obstacles to vaccination were fear of adverse events (ß = -0.4; p ≤ 0.0001) and lack of education (ß = 0.23; p = 0.031), which were found to be significant in bivariate and multivariate analyses. At the proximal level, community mobilization (ß = 0.26; p = 0.008) and attendance at health camp (ß = 0.21; p ≤ 0.0001) were found to enhance full immunization coverage. On the other hand, the most prominent reason for not attending health camp included no need to attend the health camp as the child was not ill (ß = -0.13; p = 0.008). CONCLUSIONS: This study found that community mobilization and attendance at health camps significantly enhanced full immunization coverage. The findings highlight the importance of community engagement and targeted interventions in improving immunization coverage and addressing barriers to healthcare seeking.

ABSTRACT

Substance misuse, obesity, mental health conditions, type 1 diabetes, cancers, and cardiovascular and chronic respiratory diseases together account for 41% of disability-adjusted life years linked to noncommunicable diseases (NCDs) among children and adolescents worldwide. However, the evidence on risk factors and interventions for this age group is scarce. Here we searched four databases to generate an evidence gap map of existing interventions and research gaps for these risk factors and NCDs. We mapped 159 reviews with 2,611 primary studies; most (96.2%) were conducted in high-income countries, and only 100 studies (3.8%) were from low- and middle-income countries (LMICs). The efficacy of therapeutic interventions on biomarkers and adverse events for NCDs appears to be well evidenced. Interventions for mental health conditions appear to be moderately evidenced, while interventions for obesity and substance misuse appear to be moderate to very low evidenced. Priority areas for future research include evaluating digital health platforms to support primary NCD prevention and management, and evaluating the impact of policy changes on the prevalence of obesity and substance misuse. Our findings highlight the wide disparity of evidence between high-income countries and LMICs. There is an urgent need for increased, targeted financing to address the research gaps in LMICs.

ABSTRACT

PURPOSE: The SARS-CoV-2 virus pandemic has left a massive global death toll in its wake. Associated restrictions, precautions and lockdowns have disrupted daily routines, which has been associated with social isolation and major health implications for the world's youth. This paper shares young adults' visions for life beyond the pandemic as it relates to the prevention and management of noncommunicable diseases (NCDs). METHODS: NCD Child hosted a global Twitter campaign for young adults, some of whom are living with NCDs, to express their reflections on life beyond the pandemic. Contributions were subjected to qualitative thematic analysis. RESULTS: 52 responses from the campaign described six main themes: Health system strengthening; Access to care; Issues of sustainability, including the environment and the economy; Human rights, equity, and social issues; Mental health, and NCD prevention. DISCUSSION: Young adults expressed optimism about postpandemic life and emphasized the importance of comprehensive intersectoral approaches to create resilient health systems.

ABSTRACT

BACKGROUND: Ongoing high neonatal mortality rates (NMRs) represent a global challenge. In 2021, of the 5 million deaths reported worldwide for children under five years of age, 47% were newborns. Pakistan has one of the five highest national NMRs in the world, with an estimated 39 neonatal deaths per 1,000 live births. Reducing newborn deaths requires sustainable, evidence-based, and cost-effective interventions that can be integrated within existing community healthcare infrastructure across regions with high NMR. METHODS: This pragmatic, community-based, parallel-arm, open-label, cluster randomized controlled trial aims to estimate the effect of Lady Health Workers (LHWs) providing an integrated newborn care kit (iNCK) with educational instructions to pregnant women in their third trimester, compared to the local standard of care in Gilgit-Baltistan, Pakistan, on neonatal mortality and other newborn and maternal health outcomes. The iNCK contains a clean birth kit, 4% chlorhexidine topical gel, sunflower oil emollient, a ThermoSpot™ temperature monitoring sticker, a fleece blanket, a click-to-heat reusable warmer, three 200 µg misoprostol tablets, and a pictorial instruction guide and diary. LHWs are also provided with a handheld scale to weigh the newborn. The primary study outcome is neonatal mortality, defined as a newborn death in the first 28 days of life. DISCUSSION: This study will generate policy-relevant knowledge on the effectiveness of integrating evidence-based maternal and newborn interventions and delivering them directly to pregnant women via existing community health infrastructure, for reducing neonatal mortality and morbidity, in a remote, mountainous area with a high NMR. TRIAL REGISTRATION: NCT04798833, March 15, 2021.
