Background Micronutrient deficiencies are a major problem among children in northern Ghana. Available local foods and existing plant-based dietary patterns among children are insufficient to meet children's nutrients requirements. Aside enhancing diets with animal source foods, most of which are expensive for rural households, entomophagy, which is culturally accepted appears to be a great alternative. Objectives This study aims to (1) document the types of insects commonly consumed and the reasons for or against entomophagy in the study area, (2) document the reasons for adding or not adding insects to household meals, and (3) determine the nutrient contribution of community-based insects in children's food. Methods Both qualitative and quantitative research methods were concurrently applied in this exploratory study (n=392 individuals; six focus group discussions) in Northern Ghana. Results Termites, crickets, grasshoppers, and caterpillars were recognized as the most prevalent edible insects in communities. These insects were largely consumed by children but presently only included in household meals by a few households. Individual, sociocultural, sensory characteristics of insects, climate, and economic aspects were cited as grounds for and against entomophagy. Existing community-based children's diets were unable to meet the acceptable Recommended Nutrient Intake (RNI)1 level of all nutrients under consideration, especially for zinc, vitamin B12, folate, and fat. Inclusion of community-based edible insects increased RNI levels for all 11 micronutrients considered and met children's zinc, vitamin B12, folate, and fat requirements. Conclusion Community-based insects demonstrated a great potential for meeting micronutrients needs of children in the research setting. Future research is required to improve households' adoption of community-based insects as part of household meals and to make insects accessible to households.

Background: Micronutrient deficiencies are a major problem among children in northern Ghana. Available local foods and existing plant-based dietary patterns among children are insufficient to meet children’s nutrients requirements. Aside enhancing diets with animal source foods, most of which are expensive for rural households, entomophagy, which is culturally accepted, appears to be a great alternative. Objectives: This study aimed to 1) document the types of insects commonly consumed and the reasons for or against entomophagy in the study area, 2) document the reasons for adding or not adding insects to household meals, and 3) determine the nutrient contribution of community-based insects in children's food. Methods: Both qualitative and quantitative research methods were concurrently applied in this exploratory study (N = 392 individuals; 6 focus group discussions) in northern Ghana. Results: Termites, crickets, grasshoppers, and caterpillars were recognized as the most prevalent edible insects in communities. These insects were largely consumed by children but presently only included in household meals by a few households. Individual, sociocultural, sensory characteristics of insects, climate, and economic aspects were cited as grounds for and against entomophagy. Existing community-based children’s diets were unable to meet the acceptable recommended nutrient intake (RNI; within a given age and gender group, the RNI is the amount of a nutrient ingested daily that would meet the needs of almost all healthy individuals in that group) level of all nutrients under consideration, especially for zinc, vitamin B-12, folate, and fat. Inclusion of community-based edible insects increased the RNI levels for all 11 micronutrients considered and met children’s zinc, vitamin B-12, folate, and fat requirements. Conclusions: Community-based insects demonstrate a great potential for meeting micronutrients needs of children in the research setting. Future research is required to improve households’ adoption of community-based insects as part of household meals and to make insects accessible to households.

2024
Lividini, K. | Campos, Hugo | Heck, S. | Birol, E. | Hareau, G.
Objectives: Inadequate vitamin A (VA) production and apparent intake are prevalent in Africa and South Asia where the disease burden of vitamin A deficiency (VAD) is concentrated. This study focused on estimating the potential impact of vitamin A-biofortified orange-fleshed sweetpotato (OFSP) on reducing the burden of VAD. Methods: Country-specific VAD-related disability-adjusted life years (DALYs) from the Institute of Health Metrics and Evaluation’s (IHME) Global Health Data Exchange (GHDx) for 1990-2019 were merged with data from the Nutrient Balance Sheets (NBS). The maximum additional amount of VA that can be supplied by the OFSP intervention was calculated and the corresponding effectiveness (E) in each country was estimated and interpreted as the maximum potential percentage reduction in DALYs. The maximum annual reductions for VAD-related disease burden were then determined as well as the total DALYs saved under various scaling scenarios. Results: Interventions scaling OFSP collectively had the potential to save up to 41% of DALYs in Sub-Saharan Africa (SSA), 23% of DALYs in Latin America and the Caribbean (LAC) and 22% of DALYs in East Asia and the Pacific (EAP) as of 2019 at maximum scale. Ethiopia, Niger, Chad, Nigeria, and Madagascar had the potential to save the most DALYs in absolute terms (greater than 50,000 DALYs). Holding the annual number of DALYs lost constant, scaling scenarios of 25% and 75% (and faster rate) indicate that SSA can save between 4.0% and 16.6% of DALYs over a 30-year period; LAC can save between 2.4% and 10.4% of DALYs; and EAP can save between 2.2% and 8.9% of DALYs. Carrying the 2015-2019 trend in DALYs lost forward resulted in similar ranges of percentages of DALYs saved though much lower in absolute terms. Under all scenarios SSA would save the greatest number of VAD-related DALYs. Conclusions: Investments in OFSP development and delivery have the potential to further reduce the burden of VAD, particularly in SSA. While significant scaling efforts are required to achieve the impacts shown here, strategies which incorporate economies of scale, such as mainstreamed breeding approaches to include vitamin A in all improved varieties, could cost-effectively achieve such levels while also addressing other food system-related goals.

Background The coronavirus disease 2019 (COVID-19) pandemic has had large negative effects on countries’ economies and individual well-being throughout the world, particularly in low- and middle-income countries. Pandemic-related changes in behavior and government restrictions in Kenya may have negatively affected food supply chains and household food access, but the empirical evidence is currently limited. Objective The study explored changes in informal milk markets, dairy consumption, and food insecurity among low-income households in urban and peri-urban Nairobi, Kenya, following the start of the COVID-19 pandemic in the country. Methods Baseline data on milk sales and consumption were collected in late 2019 from dairy vendors operating in the informal sector and their dairy customers. We conducted two longitudinal telephone-surveys with the same study participants in July and September-October 2020, respectively. Results At the first follow up, the volume of milk sold by informal vendors had dropped by 30% compared to their baseline level and the volume of milk from informal markets consumed by households decreased by 23%. By the second follow up, the volume of milk sold and consumed had recovered somewhat but remained lower than the volume observed one year prior in the same season. Large reductions in the consumption of other animal-source products were also observed. The rate of food insecurity increased by 16 and 11 percentage points in the first and second follow up periods, respectively compared to baseline. Conclusions The evidence therefore suggests that the timing of the pandemic and the related restrictions were associated with a decrease in the supply and consumption of milk from informal markets in Nairobi, and a decrease in the food security of peri-urban consumers.

Background: Recent evidence suggests that diet inequities between men and women may have diminished within rural Bangladeshi households. However, this has not been directly tested with appropriate physiologic adjustments and it is unclear whether changes have occurred across socioeconomic strata. Understanding intrahousehold dietary patterns at different points on the income and food-security distribution in rural Bangladesh—particularly, within ultrapoor and farm households—is important for appropriate design of gender-sensitive and nutrition-sensitive interventions, which often target these groups. Objective: Using 2012 and 2016 data, we aimed to examine gender differences in diet quantity and quality among ultrapoor and farm households in rural Bangladesh. Methods: The study used baseline 24-h dietary data from 2 randomized control trials conducted in rural Bangladesh: the Transfer Modality Research Initiative (ultrapoor households) and the Agriculture, Nutrition, and Gender Linkages project (farm households). Ordinary least squares regressions with household-level fixed effects tested for gender differences among constructed diet measures, such as caloric intake, caloric adequacy ratio, dietary diversity score, global diet quality score, and probability of consuming moderate or high levels of healthy food groups. Results: In both samples, on average, women consumed fewer calories than men in the same households but consumed near equal or more in reference to their caloric needs. Women scored <1% lower than men on diet quality indicators and showed similar probabilities to men of consuming healthy foods. Most men and women in both samples were calorically inadequate (>60%) and recorded poor diet quality scores that indicated high risk of nutrient inadequacy and chronic disease (>95%). Conclusions: In both ultrapoor and farm households, although men record higher intake quantities and diet quality scores, the apparent male advantage disappear when energy requirements and the magnitudes of difference are considered. Diets of men and women in these rural Bangladeshi households are equitable but suboptimal.

Boedecker, Julia | Lachat, Carl | Hawwash, Damme | Damme, Patrick van | Nowicki, Marisa | Termote, Céline
There is a current need for better understanding the impact of nutrition-sensitive agriculture interventions. This study is based on a community-based participatory project that diversified diets of women and children by making use of local food biodiversity. This retrospective impact pathway analysis aims at explaining why and how impact was reached. Pathway analysis in nutrition-sensitive agriculture can provide valuable understanding on how and why dietary improvements have been achieved in an intervention. The approach can hence be instrumental in addressing the current demand within the field on understanding the progress and impact of interventions. Pathway analysis also helps to address knowledge gaps regarding theoretical frameworks, as in the present study, concerning women empowerment pathways.

Objectives: Unsafe food contributes to 600 million cases of foodborne illness and 420,000 deaths annually. Existing methods used to evaluate food safety risks overlook consumers’ perspectives coming from their everyday experiences that influence their food choices. Our objective was to develop a cross-culturally appropriate and user-friendly scale to assess consumers’ experiences related to food safety in low- and middle-income countries. This study identified the constructs that constitute the experiences of food safety that the scale should reflect. Methods: In-depth interviews were conducted with urban households in Bangladesh (n=51), Ethiopia (n=50), and Vietnam (n=41). Eligible households had children aged 2–5 years and members serving as primary food purchasers, preparers, and caregivers. Interviews explored attitudes, perceptions, and lived experiences related to food safety. Data were analyzed using a constant comparative method. Results: Respondents expressed awareness of biological and chemical contaminants in foods. Concerns about chemical additives and food adulteration were common, fueled by beliefs that these hazards cause chronic illnesses. Personal and familial experiences with foodborne illness reinforced caution when buying foods. Religious and cultural beliefs shaped how respondents explained and responded to food safety concerns, with some attributing illness symptoms to spiritual causes. Trust in food vendors was rooted in reputation, visible cleanliness, and willingness to rectify issues (e.g., exchange items). Respondents differentiated their extent of scrutinizing safety based on food type: staples such as rice and pulses were assessed more by vendor credibility, whereas perishables such as fish and meat underwent direct, detailed inspections. Low transparency in food sourcing and how vendors prepared foods were persistent concerns. Conclusions: Trust, perceived transparency, risk perceptions, and past incidents shaped consumers’ mental representations and behaviors related to food safety. Interviews underscored the centrality of context and sensory-based quality indicators, suggesting that scenario-based assessments are more appropriate than generic risk-reduction items.

This study examined mother-child differences in vitamin A-rich food consumption and conduct a comparative analysis of three food security indicators on household vitamin A-rich food consumption for 375 mother-child dyads from selected sweet potato growing households in Uganda. This study examined baseline data collected by the International Potato Centre (IPC) for an initiative on the development and delivery of biofortified crops in Uganda. Dietary intake and livelihoods data was collected from women residing in households that grew sweet potatoes in selected regions in Uganda. Eligibility criteria included women who were pregnant or lactating and/or had children 6–24 months. The analytical dataset had 375 woman-child dyads. An adjusted Hellen Keller International (HKI) guide was used to examine data on vitamin A consumption. Scores were weighted for animal- and plant-based sources of vitamin A. Data were stratified by woman or child to allow for within- and between-person variances in vitamin A-rich food consumption. Dependent sample Student's t-tests, Pearson's correlation analysis and a repeated measure analysis of covariance (ANCOVA) tested for differences in the vitamin A-rich food consumption mother-child dyads. There was a statistically significant difference in the mean consumption of vitamin A-rich foods for women and children (F (1,370) = 6.51, p = .011). Women had a higher vitamin A consumption (M = 2.08, SD = 2.11) than children in the same household (M = 1.39, SD = 2.17). This was qualified by a significant interaction with the household wealth index (F (1,370) = 4.31, p = .039), however not with household dietary diversity (F (1,370) = 3.16, p = .07), and household food insecurity access (F (1,370) = 0.32, p = .57). HDDS and the wealth index were associated with the mother's consumption of vitamin A-rich food but not with the children's. Initiatives that target mother-child dyads should be aware of factors such as intrahousehold food distribution and cultural practices that may differentially impact child consumption of vitamin A-rich and other micronutrient-rich foods. Child-friendly initiatives are recommended to maximize nutritional benefits for children under five years. International Potato Center and the University of Massachusetts Amherst.

Biofortification was coined as a term to define a plant breeding strategy to increase the micronutrient content of staple food crops to reduce the burden of micronutrient deficiencies in low- and middle-income countries (LMICs). In 2003, the HarvestPlus program, based in the centers comprising the Consultative Group on International Agricultural Research (CGIAR), was initiated to implement the biofortification strategy. This paper discusses what has been achieved, what has been learned, and the key challenges to embed biofortification in food systems and to expand its impact. Cost-effectiveness is key to the biofortification strategy. Biofortification piggybacks on the agronomically-superior varieties being developed at agricultural research centers. Central plant breeding research discoveries can be spread globally. Farmers have every motivation to adopt the latest high-yielding, high profit crops. High productivity leads to lower food prices. As a consequence, consumers can increase their mineral and vitamin intakes at no additional cost by substituting biofortified staple foods one-for-one for non-biofortified staple foods. After twenty years of investment, biofortified staple food crops are being produced by farmers in over 40 countries and are eaten by hundreds of millions of people. Published nutrition trials have shown nutrient-rich crops to be efficacious. The biofortification strategy is now recognized by the international nutrition community as one effective approach among several interventions needed to reduce micronutrient deficiencies. This is a promising beginning. However, biofortification is still a newly emerging technology. A limitation of biofortification as implemented to date is that densities of single nutrients have been increased in given staple food crops. To reach a higher trajectory, the impacts of biofortification can be multiplied several-fold using genetic engineering and other advanced crop development techniques to combine multiple-nutrient densities with climate-smart traits.

2024

High intakes of sodium, sugar, saturated fats, and trans fats contributed to 187.7 million disability adjusted life years (DALYs) from non-communicable diseases globally. Understanding of the global evidence on interventions to reduce consumption of various types of unhealthy food across diverse contexts is needed. We conducted a scoping review to examine the existing evidence on behavior change interventions (BCIs) to address unhealthy food consumption. Through a systematic search of 3 databases conducted in December 2022, 2,730 records were retrieved, and 145 studies met the eligibility criteria for review. Only 19% of the studies (n=28) were from low and middle-income countries. The key target group for most BCIs was adults ≥20 years (n=79). Interventions were conducted across 7 types of settings: schools (n=52), digital (n=30), community (n=28), home (n=14), health facility (n=12), worksite (n=6), and market (n=3). There were 4 mutually inclusive intervention types – information, education, and communication (IEC) (n=141); food/beverage substitution (n=10); interactive games (n=7); and labeling/warnings at point of purchase (n=3). The study outcomes included consumption of sugar-sweetened beverages (n=74), packaged salty snacks/fast food (n=61), sweets (n=43), and saturated fat (n=41). Drivers of food choice behaviors such as knowledge, attitudes, and beliefs; motivation and expectancies; and self-efficacy were reported in 43% of studies. Based on reported impact of BCIs on study outcomes, more interventions targeted at adults had positive impacts compared to those targeted at children; intervention packages including multiple IEC components also reported impacts more often than simple informational interventions. Interpretation of the findings was complicated by the lack of comparability in interventions, evaluation designs, outcome measures of unhealthy food consumption, duration of interventions, and study contexts. Future studies should invest in critical yet under-represented regions, examine behavioral determinants of unhealthy food consumption and the sustainability of behavior change, and conduct further analysis of effectiveness from experimental studies.

Background The double burden of malnutrition (DBM), characterized by concurrent undernutrition and overnutrition, is a growing global concern. Families share resources and eating behaviors and programs often target households, yet evidence of the DBM at the family level is scarce. Objectives This study examined trends and inequality in the intrahousehold DBM in India between 2006 and 2021. Methods Data were from 3 waves of India’s National Family Health Survey (NFHS 2006, 2016, and 2021). We examined 3 types of household member (with children aged <5 y) combinations: mother–child (N = 328,039 across 3 waves), father–child, and parent (mother and father)–child (N = 47,139 for each pair). The DBM was defined as one or more individuals with undernutrition (either wasting or stunting in children or underweight in adults) and one or more overweight individuals within the same household. DBM was examined over time, at national and subnational levels, and by residence and wealth. Results Nearly all DBM was in the form of an overweight parent and an undernourished weight or stunted child. The prevalence of parent–child DBM increased from 15% in 2006 to 26% in 2021. Father–child pairs experienced the most rapid DBM increase, from 12% in 2006 to 22% in 2021, an 83% increase, driven by increasing overweight among men. In 2021, the DBM was highest in North-Eastern and Southern states, and among relatively rich households from urban areas. The increase in the DBM was faster in rural areas and among poor households compared with that in urban areas and rich households. Urban–rural and rich–poor inequalities in the DBM have decreased over time. Conclusions The intrahousehold DBM has increased over time, affecting 1 in 4 households in India in 2021. Family-based interventions that can simultaneously address child underweight and parent overweight are required to address India’s increasing intrahousehold DBM.

Background The double burden of malnutrition (DBM), characterized by concurrent undernutrition and overnutrition, is a growing global concern. Families share resources and eating behaviors and programs often target households, yet evidence of the DBM at the family level is scarce. Objectives This study examined trends and inequality in the intrahousehold DBM in India between 2006 and 2021. Methods Data were from 3 waves of India’s National Family Health Survey (NFHS 2006, 2016, and 2021). We examined 3 types of household member (with children aged <5 y) combinations: mother–child (N = 328,039 across 3 waves), father–child, and parent (mother and father)–child (N = 47,139 for each pair). The DBM was defined as one or more individuals with undernutrition (either wasting or stunting in children or underweight in adults) and one or more overweight individuals within the same household. DBM was examined over time, at national and subnational levels, and by residence and wealth. Results Nearly all DBM was in the form of an overweight parent and an undernourished weight or stunted child. The prevalence of parent–child DBM increased from 15% in 2006 to 26% in 2021. Father–child pairs experienced the most rapid DBM increase, from 12% in 2006 to 22% in 2021, an 83% increase, driven by increasing overweight among men. In 2021, the DBM was highest in North-Eastern and Southern states, and among relatively rich households from urban areas. The increase in the DBM was faster in rural areas and among poor households compared with that in urban areas and rich households. Urban–rural and rich–poor inequalities in the DBM have decreased over time. Conclusions The intrahousehold DBM has increased over time, affecting 1 in 4 households in India in 2021. Family-based interventions that can simultaneously address child underweight and parent overweight are required to address India’s increasing intrahousehold DBM. | PR | IFPRI3; 2 Promoting Healthy Diets and Nutrition for all; G Cross-cutting gender theme; Capacity Strengthening; POSHAN | Nutrition, Diets, and Health (NDH); Food and Nutrition Policy
