Disruptions and adaptations of an urban nutrition intervention delivering essential services for women and children during a major health system crisis in Dhaka, Bangladesh

Systematic crises may disrupt well-designed nutrition interventions. Continuing services requires understanding the intervention paths that have been disrupted and adapting as crises permit. Alive & Thrive developed an intervention to integrate nutrition services into urban antenatal care services in Dhaka, which started at the onset of COVID-19 and encountered extraordinary disruption of services. We investigated the disruptions and adaptations that occurred to continue the delivery of services for women and children and elucidated how the intervention team made those adaptations. We examined the intervention components planned and those implemented annotating the disruptions and adaptations. Subsequently, we detailed the intervention paths (capacity building, supportive supervision, demand generation, counselling services, and reporting, data management and performance review). We sorted out processes at the system, organizational, service delivery and individual levels on how the intervention team made the adaptations. Disruptions included decreased client load and demand for services, attrition of providers and intervention staff, key intervention activities becoming unfeasible and clients and providers facing challenges affecting utilization and provision of services. Adaptations included incorporating new guidance for the continuity of services, managing workforce turnover and incorporating remote modalities for all intervention components. The intervention adapted to continue by incorporating hybrid modalities including both original activities that were feasible and adapted activities. Amidst health system crises, the adapted intervention was successfully delivered. This knowledge of how to identify disruptions and adapt interventions during major crises is critical as Bangladesh and other countries face new threats (conflict, climate, economic downturns, inequities and epidemics).

Computer vision–assisted dietary assessment through mobile phones in female youth in urban Ghana: Validity against weighed records and comparison with 24-h recalls

Background Gaps persist in the data on diets and on the validity of dietary assessment methods in youth in low-income and middle-income countries (LMICs) due to costs constraints. Although computer vision–assisted dietary assessment tools have been proposed, limited evidence exists on their validity in LMICs. Objectives This study aimed to validate FRANI (Food Recognition Assistance and Nudging Insights), a mobile phone application with computer vision–assisted dietary assessment, against weighed records (WRs) and compare with 24-h recalls (24HR), in female youth in Ghana. Methods Dietary intake was assessed on 2 nonconsecutive days using FRANI, WR, and 24HR in females aged 18–24 y recruited at the University of Ghana, Accra (n = 64). Equivalence was examined by comparing intake mean ratios (FRANI/WR and 24HR/WR) with error margins of 10%, 15%, and 20%, using mixed-effect regression models adjusting for repeated measures. Agreement between methods was assessed using the concordance correlation coefficient (CCC). Results Equivalence for FRANI and WR was found at 10% bound for riboflavin and vitamin B-6 intakes and at 15% bound for protein, fat, calcium, folate, iron, thiamine, vitamin C, and zinc intakes. Energy, fiber, vitamin A, and niacin intakes were equivalent at 20% bound. Comparisons between 24HR and WR found no estimates within a 10% bound. Protein, iron, niacin, riboflavin, and zinc intakes were equivalent at a 15% bound; folate, thiamine, and vitamin B-12 intakes were equivalent at a 20% bound. CCCs between FRANI and WR ranged from 0.45 to 0.74 (mean: 0.60) and between 24HR and WR ranged from 0.48 to 0.76 (mean: 0.63). Omission errors were 15% for FRANI and 22% for 24HR. Intrusion errors were 22% for FRANI and 18% for 24HR. Conclusions FRANI-assisted dietary assessment accurately estimates nutrient intake and performed as accurately as 24HR in female youth in Ghana. Although improvements in computer vision–assisted diet assessment are possible, emerging evidence on FRANI suggests its readiness for scale-up.

Compliance with food safety measures and their economic impact on smallholder dairy farmers: Evidence from the Indo-Gangetic plains of India

Compliance with food safety measures and their economic impact on smallholder dairy farmers: Evidence from the Indo-Gangetic plains of India

This study examines the adoption and economic impact of compliance with food safety measures (FSM) using cross-sectional farm-level data from three key states in the Indo-Gangetic Plains, Bihar, Punjab, and Uttar Pradesh, in 2023. The majority of the farmers were operating on marginal and small plots. A Food Safety Index (FSI) derived from 71 distinct practices was used as a quantitative measure of adoption of compliance with FSM. The study assigns 0.60, 0.23, and 0.17 wt to microbiological, physical, and chemical safety measures, respectively, to derive FSI. Determinants of compliance with FSM were analysed using multiple linear regression and ordered logistic model, while Generalized propensity score (GPS) was used to assess the economic impact of compliance with FSM on farm-level performance indicators. The findings indicate that farmers are adopting a moderate level (0.48–0.58) of the FSI. Various socio-economic and demographic factors, such as education, income, marketing channel, training exposure, awareness level, and infrastructure, significantly influence the adoption of FSM. The impact assessment reveals that compliance with FSM correlates with milk prices, productivity, and profitability. However, a lower level of compliance may not yield significant improvements in milk productivity. The study suggests incentivization through pricing reforms, improving infrastructure, strengthening formal marketing channels, and raising awareness through training.

The 2024 Global Food Policy Report

Food systems and diets underpin many critical challenges to public health and environmental sustainability, including malnutrition, noncommunicable diseases, and climate change, but healthy diets have the unique potential to reshape the future for both human and planetary well-being. Drawing on recent evidence and experience, the 2024 Global Food Policy Report highlights opportunities for transforming food systems to ensure sustainable healthy diets for all.

Building Drought Resilience: How Ethiopia’s SPIR Program Protects Women and Families (AMH SUB)

Climate change is accelerating drought shocks and deepening gender disparities. In Ethiopia, researchers from the CGIAR Initiative on Gender Equality (HER+) partnered with World Vision, CARE, and ORDA Ethiopia to assess whether SPIR, a social protection program with livelihood and nutrition components, helped poor rural women and their households cope with droughts.

For more than three decades, IFPRI has worked with the Government of Ethiopia to provide evidence-based advice on the development of the country’s agricultural sector.

IFPRI’s research and policy recommendations led to the establishment of Ethiopia’s Agricultural Transformation Agency (ATA) in 2010, which continues to play a critical role in guiding the country’s agricultural development and sustainability.

Tamsin Zandstra, Gashaw T. Abate, Shahidur Rashid, and Nicholas Minot outline how IFPRI’s long-term strategic research support to the ATA has led to several tangible government policy outcomes.
