To assess how well national sentinel lists of the most frequently consumed foods in each food group capture data at subnational levels to measure minimum diet diversity (MDD).

We analysed data from seven surveys with 24-h open dietary recalls to evaluate: (1) the percentage of reported foods that were included in each sentinel food list; (2) whether these lists captured consumption of some food groups better than others and (3) differences between estimates of dietary diversity calculated from all food items mentioned in the open 24-h recall v. only food items included in the sentinel lists.

Seven subnational areas: Bangladesh (2), Benin, Colombia, Kenya, Malawi and Nepal.

8094 women 15–49 years; 4588 children 6–23 months.

National sentinel food lists captured most foods reportedly consumed by women (84 %) and children (86 %). Food groups with the highest variability were ‘other fruits’ and ‘other vegetables.’ MDD calculated from the sentinel list was, on average, 6·5 (women) and 4·1 (children) percentage points lower than when calculated from open 24-h recalls, with a statistically significant difference in most subnational areas.

National sentinel food lists can provide reliable data at subnational levels for most food groups, with some variability by country and sub-region. Assessing the accuracy of national sentinel food lists, especially for fruits and vegetables, before using them at the subnational level could avoid potentially underestimating dietary diversity and provide more accurate local information for programmes, policy and research.

This study assesses change in caregiver practices after integrating responsive care and early learning (RCEL) in nutrition and health services and community platforms in northern Ghana.

We trained health facility workers and community health volunteers to deliver RCEL counselling to caregivers of children under 2 years of age through existing health facilities and community groups. We assessed changes in caregivers’ RCEL practices before and after the intervention with a household questionnaire and caregiver–child observations.

The study took place in Sagnarigu, Gushegu, Wa East and Mamprugu-Moagduri districts from April 2022 to March 2023. Study sites included seventy-nine child welfare clinics (CWC) at Ghana Health Service facilities and eighty village savings and loan association (VSLA) groups.

We enrolled 211 adult caregivers in the study sites who had children 0–23 months at baseline and were enrolled in a CWC or a VSLA.

We observed improvements in RCEL and infant and young child feeding practices, opportunities for early learning (e.g. access to books and playthings) in the home environment and reductions in parental stress.

This study demonstrates the effectiveness of integrating RCEL content into existing nutrition and health services. The findings can be used to develop, enhance and advocate for policies integrating RCEL into existing services and platforms in Ghana. Future research may explore the relationship between positive changes in caregiver behaviour and improvements in child development outcomes as well as strategies for enhancing paternal engagement in care practices, improving child supervision and ensuring an enabling environment.

Caregivers require tangible (e.g. food and financial) and intangible resources to provide care to ensure child health, nutrition and development. Intangible resources include beliefs and knowledge, education, self-efficacy, perceived physical health, mental health, healthy stress levels, social support, empowerment, equitable gender attitudes, safety and security and time sufficiency. These intangible caregiver resources are included as intermediate outcomes in nutrition conceptual frameworks yet are rarely measured as part of maternal and child nutrition research or evaluations. To facilitate their measurement, this scoping review focused on understudied caregiver resources that have been measured during the complementary feeding period in low- and lower-middle-income countries.

We screened 9,232 abstracts, reviewed 277 full-text articles and included 163 articles that measured caregiver resources related to complementary feeding or the nutritional status of children 6 months to 2 years of age.

We identified measures of each caregiver resource, though the number of measures and quality of descriptions varied widely. Most articles (77 %) measured only one caregiver resource, mental health (n 83) and social support (n 54) most frequently. Psychometric properties were often reported for mental health measures, but less commonly for other constructs. Few studies reported adapting measures for specific contexts. Existing measures for mental health, equitable gender attitudes, safety and security and time sufficiency were commonly used; other constructs lacked standardised measures.

Measurement of caregiver resources during the complementary feeding period is limited. Measuring caregiver resources is essential for prioritising caregivers and understanding how resources influence child care, feeding and nutrition.

To compare the agreement and cost of two recall methods for estimating children’s minimum dietary diversity (MDD).

We assessed child’s dietary intake on two consecutive days: an observation on day one, followed by two recall methods (list-based recall and multiple-pass recall) administered in random order by different enumerators at two different times on day two. We compared the estimated MDD prevalence using survey-weighted linear probability models following a two one-sided test equivalence testing approach. We also estimated the cost-effectiveness of the two methods.

Cambodia (Kampong Thom, Siem Reap, Battambang, and Pursat provinces) and Zambia (Chipata, Katete, Lundazi, Nyimba, and Petauke districts).

Children aged 6–23 months: 636 in Cambodia and 608 in Zambia.

MDD estimations from both recall methods were equivalent to the observation in Cambodia but not in Zambia. Both methods were equivalent to the observation in capturing most food groups. Both methods were highly sensitive although the multiple-pass method accurately classified a higher proportion of children meeting MDD than the list-based method in both countries. Both methods were highly specific in Cambodia but moderately so in Zambia. Cost-effectiveness was better for the list-based recall method in both countries.

The two recall methods estimated MDD and most other infant and young child feeding indicators equivalently in Cambodia but not in Zambia, compared to the observation. The list-based method produced slightly more accurate estimates of MDD at the population level, took less time to administer and was less costly to implement.

For young children experiencing an illness, adequate nutrition is critical for recovery and to prevent malnutrition, yet many children do not receive the recommended quantities of food during illness and recuperation. Our research applied a behavioural science lens to identify drivers of feeding behaviours, including barriers inhibiting caregivers from following the feeding guidelines.

In 2021, we conducted qualitative research informed by the behavioural design process. Data from in-depth interviews and observations were analysed for themes.

Research was conducted in South Kivu, Democratic Republic of the Congo.

Research participants included caregivers of young children, other family members, health workers and other community members.

Five key findings about behavioural drivers emerged: (1) poverty and scarcity impose practical constraints and a cognitive and emotional burden on caregivers; (2) health providers are distracted and discouraged from counselling on feeding during sick visits; (3) a focus on quality and hesitations about quantity obscure benefits of feeding greater amounts of available foods; (4) perceptions of inappropriate foods limit caregivers’ choices; and (5) deference to a child’s limited appetite leads to missed opportunities to encourage them to eat.

Each of these behavioural drivers is triggered by one or more addressable features in caregivers’ and health workers’ environment, suggesting concrete opportunities for programmes to support caregivers and health workers to improve feeding of young children during illness and recovery. In other settings where these features of the environment are similar, the insights and programming implications are likely to translate.

To assess changes in caregiver practices for young children after integrating the Responsive Care and Early Learning (RCEL) Addendum package into nutrition services after 10 months of implementation.

We measured changes in RCEL practices through a pre- and post-intervention assessment comprising a household survey and observations. To implement the intervention, we trained health service staff and community volunteers to deliver RCEL counselling to caregivers of children 0–23 months of age through existing community and facility-level platforms.

Caregivers of children aged 0–23 months at baseline.

We found statistically significant increases in RCEL practices, availability of early learning opportunities in the home, decreases in parenting stress and improvements in complementary feeding practices after the intervention implementation period.

Findings show that delivery of RCEL counselling using the RCEL Addendum was associated with improved responsive care practices and early learning opportunities. We also found that integration of RCEL with infant and young child feeding counselling did not disrupt nutrition service delivery or negatively affect complementary feeding outcomes, but rather suggest synergistic benefits. Given the importance of providing holistic care to support optimal early childhood development, these findings provide new evidence on how to strengthen the delivery of nurturing care services in the Kyrgyz Republic.

The objective of this study was to explore adolescent dietary practices, related norms and acceptable communication platforms in northern Nigeria to inform future nutrition project design.

This was a qualitative formative research study. We used purposive sampling and conducted thirty focus group discussions with male and female adolescents aged 10–14 and 15–19 years (n 180) and six with adult influencers (n 36). We also administered a 24-h dietary recall with the adolescents using the Diet Quality Questionnaire.

The study was conducted in urban and rural areas in three states in northern Nigeria.

Adolescents reported consuming six nutritious food groups the previous day on average. However, there was a wide disparity and only half consumed all five recommended food groups. Adolescents’ food choices were influenced by perceptions of the functional and physical benefits of nutritious foods and preferences for satisfying foods. Diverse foods were available in the food environment, but affordability constrained access to nutritious foods. Limited access to income and gender norms constrained adolescent agency over food choice. Girls, particularly those who were pregnant, had less agency related to food than boys. Adolescents thought that peers should be reached through group discussions, radio and phones, among other communication platforms.

Adolescents consumed relatively diverse diets. Adolescent food choice was influenced by their embodied experience and knowledge related to nutrition and taste, home food environment and circumscribed agency. Opportunities exist to support healthy diets for adolescents by strengthening adolescents’ embodied knowledge, food environments and social support.

To evaluate the impact of a counselling programme to strengthen the health and nutrition behaviours of caregivers of children under 2 and the sustainability of that impact through reduced intervention intensity one year later.

The programme trained community- and facility-based health staff to provide nutrition counselling. We conducted an impact evaluation with a modified stepped-wedge design using difference-in-differences analysis to compare indicator changes in an intervention group to a comparison group (midterm survey) and then a full intervention group to a light intervention group (final survey).

Batken and Jalal-Abad oblasts, the Kyrgyz Republic, 2020–2023.

Caregivers of children under 2 provided 6253 responses in three telephone surveys.

We observed statistically significant differences between the intervention and comparison groups at midterm for the percentage of children consuming vitamin A-rich foods; an increase in the intervention group (58–62 %) and a decrease in the comparison group (61–57 %). We observed similar results with exclusive breastfeeding (51–55 % in the intervention group and 48–40 % in the comparison group). There were also positive differences in other health and nutrition indicators. With the final survey results, in general, we observed statistically significant differences indicating a bigger change in full intervention areas compared to light intervention areas. We observed small negative changes in many indicators in light intervention areas.

This evaluation highlights the importance of continued support for local interventions, particularly counselling programmes, to foster optimal nutrition behaviours.

To assess the potential contribution of large-scale food fortification (LSFF) towards meeting dietary micronutrient requirements in Tanzania.

We used household food consumption data from the National Panel Survey 2014–15 to estimate fortifiable food vehicle coverage and consumption (standardised using the adult female equivalent approach) and the prevalence at risk of inadequate apparent intake of five micronutrients included in Tanzania’s fortification legislation. We modelled four LSFF scenarios: no fortification, status quo (i.e. compliance with current fortification contents) and full fortification with and without maize flour fortification.

A nationally representative sample of 3290 Tanzanian households.

The coverage of edible oils and maize and wheat flours (including products of wheat flour and oil such as bread and cakes) was high, with 91 percent, 88 percent and 53 percent of households consuming these commodities, respectively. We estimated that vitamin A-fortified oil could reduce the prevalence of inadequate apparent intake of vitamin A (retinol activity equivalent) from 92 percent without LSFF to 80 percent with LSFF at current fortification levels. Low industry LSFF compliance of flour fortification limits the contribution of other micronutrients, but a hypothetical full fortification scenario shows that LSFF of cereal flours could substantially reduce the prevalence at risk of inadequate intakes of iron, zinc, folate and vitamin B12.

The current Tanzania LSFF programme likely contributes to reducing vitamin A inadequacy. Policies that support increased compliance could improve the supply of multiple nutrients, but the prominence of small-scale maize mills restricts this theoretical benefit.

This study examined drivers and barriers to iron and folic acid supplementation and consumption of iron- and vitamin A-rich foods among women of reproductive age and adolescent girls in Niger.

This was an exploratory qualitative study using focus group discussions and semi-structured interviews.

This study was conducted in the rural areas of three districts in Maradi and Zinder regions of southern Niger.

The study included a purposive sample of 56 WRA (15–49 years), 34 non-pregnant adolescent girls (10–14 years), 105 family members and community leaders, 32 health workers and 12 national and regional level stakeholders.

Respondents demonstrated widespread knowledge of recommendations for iron and folic acid during pregnancy and had positive attitudes towards supplements. However, supply barriers were significant, and adherence was limited by side effects, among other constraints. Despite knowledge about and positive attitudes towards micronutrient-source foods, respondents reported that limited food access was an overriding constraint to increasing consumption. Women of reproductive age were seen as nutritionally vulnerable; however, husbands were often not able to provide sufficient nutritious food, and there was a cultural expectation that wives serve themselves food last. Adolescent girls were not seen as nutritionally vulnerable, and there was little family support for their consumption of nutritious foods.

Projects should work with local actors to develop multi-pronged solutions that address supply and access barriers for iron and folic acid and micronutrient-rich foods and to improve social support for nutrition.
