listen audio

Study Justification:
– Malnutrition, particularly severe acute malnutrition (SAM), is a leading cause of death among children under 5 in low- and middle-income countries (LMICs).
– Reducing malnutrition is crucial for decreasing child mortality, improving maternal health, and achieving sustainable development goals related to nutrition and healthy lives.
– This study aims to identify and understand the risk factors associated with SAM among under-5 children in LMICs.
Highlights:
– The study analyzed data from 51 recent demographic and health surveys conducted in LMICs between 2010 and 2018.
– A multivariable Bayesian logistic multilevel regression model was used to analyze the association between individual and contextual risk factors and SAM.
– The prevalence of SAM varied across countries, with rates ranging from 0.1% in Guatemala and Peru to 9.9% in Timor-Leste.
– Several risk factors were identified, including being male, being an infant, having low birth weight, having mothers with no formal education, belonging to poorer households, and having no access to media.
– Other factors associated with SAM included living in rural areas, residing in neighborhoods with high illiteracy and unemployment rates, and living in countries with high deprivation and a high rural population percentage.
Recommendations:
– The findings highlight the need to revitalize existing policies and implement interventions to prevent and rescue children from SAM at the individual, community, and societal levels in LMICs.
– Achieving sustainable development goals related to poverty reduction, quality education, and reduced inequalities will contribute to the eradication of SAM.
– Targeted interventions should focus on improving access to education, healthcare, and media, as well as addressing poverty and deprivation in rural areas.

Objectives: Malnutrition is one of the main reasons for death among children <5 years of age in low- and middle-income countries (LMICs). It accounts for about one-third of preventable deaths among children. Reduction of malnutrition, especially severe acute malnutrition (SAM), is critical, directly or indirectly, to a targeted decrease in child mortality and improvement in maternal health. It would also help achieve sustainable development goal 2 (improvement of nutrition across the board) and sustainable development goal 3 (ensuring healthy lives and well-being promotion for all at all ages). The aim of this study was to develop and test a model of risk factors associated with SAM among under-5 children in LMICs. Methods: We used 51 recent demographic and health-surveys, cross-sectional, nationally representative data collected between 2010 and 2018 in LMICs. We used multivariable Bayesian logistic multilevel regression models to analyze the association between individual compositional and contextual risk factors associated with SAM. We analyzed information on 532 680 under-5 children (level 1) nested within 55 823 communities (level 2) from 51 LMICs (level 3). Results: The prevalence of SAM ranged from 0.1% in both Guatemala and Peru to 9.9% in Timor-Leste. Male children, infants, low birth weight children, children whose mothers had no formal education, those from poorer households, and those with no access to any media were more likely to have SAM. Additionally, children from rural areas, neighborhoods with high illiteracy and high unemployment rates, and those from countries with high intensity of deprivation and high rural population percentage were more likely to have SAM. Conclusion: Individual compositional and contextual factors were significantly associated with SAM. Attainment of sustainable development goals 1, 4, and 10 will automatically contribute to the eradication of SAM, which in turn leads to the attainment of sustainable development goals 2 and 3. These findings underscore the need to revitalize existing policies and implement interventions to rescue and prevent children from having SAM at the individual, community, and societal levels in LMICs.

Based on the provided description, here are some potential innovations that could improve access to maternal health:

1. Mobile Health (mHealth) Applications: Develop and implement mobile applications that provide information and resources related to maternal health, including nutrition, prenatal care, and postnatal care. These apps can be easily accessible to women in low- and middle-income countries (LMICs) through their smartphones, helping them make informed decisions about their health.

2. Telemedicine: Establish telemedicine services that allow pregnant women in remote areas to consult with healthcare professionals through video calls or phone calls. This can help overcome geographical barriers and provide access to prenatal care, monitoring, and guidance, especially in areas with limited healthcare facilities.

3. Community Health Workers: Train and deploy community health workers who can provide essential maternal health services, including antenatal care, education on nutrition and hygiene, and postnatal care.

4. Maternal Health Vouchers: Implement voucher programs that provide financial assistance to pregnant women, enabling them to access essential maternal health services, such as prenatal check-ups, delivery care, and postnatal care. These vouchers can be distributed through community health centers or local organizations.

5. Maternal Health Clinics on Wheels: Set up mobile clinics equipped with necessary medical equipment and staffed by healthcare professionals. These clinics can travel to remote areas, providing comprehensive maternal health services, including prenatal care, screenings, vaccinations, and referrals for high-risk pregnancies.

6. Public-Private Partnerships: Foster collaborations between public and private sectors to improve access to maternal health services. This can involve leveraging private healthcare providers and facilities to expand coverage and ensure quality care for pregnant women in LMICs.

7. Health Education Programs: Develop and implement targeted health education programs that focus on maternal health, including nutrition, family planning, and safe delivery practices. These programs can be conducted in schools, community centers, and through mass media channels to reach a wider audience.

8. Maternal Health Monitoring Systems: Establish robust monitoring systems to track maternal health indicators and identify areas with high prevalence of severe acute malnutrition (SAM) among under-5 children. This data can help policymakers and healthcare providers allocate resources and implement targeted interventions to improve maternal health outcomes.

It is important to note that these recommendations are general and may need to be tailored to specific contexts and resources available in LMICs.
