Background: Diet quality during infancy can influence nutrient intake and ultra-processed foods (UPFs) consumption throughout later childhood., Objectives: This study investigated the predictive validity of Infant Diet Quality Index (IDQI) scores from 0 to 1 y of age and consumption of select nutrients and UPFs at different time points in low-income children aged 2-5 y., Methods: Dietary surveys and 24-h dietary recalls collected between ages 0 and 12 months from 2613 Special Supplemental Women, Infants, and Children Infant Toddler Feeding Practices Study-2 participants were used to assess infant diet quality by final IDQI score ranging from 0 (nonadherence to dietary guidelines) to 1 (complete adherence to guidelines). Single 24-h recalls collected across multiple time points per child aged between 2 and 5 y were used to determine nutrient intakes: vitamin B12 (μg), vitamin D (μg), calcium (mg), iron (mg), zinc (mg), potassium (mg), saturated fat (g), dietary fiber (g), and added sugars (g). Likewise, Nova was used to classify foods (to estimate the percentage of energy from foods) by level of industrial processing at each point in time across ages 2-5 y. Survey-weighted regression analyses estimated associations between total IDQI score and nutrient intake and percentage of energy consumption from each Nova food group at each age between 2-5 y., Results: IDQI scores based on diet quality from 0-1 y of age were positively associated with children's dietary fiber and potassium intake at ages 2-5 y. Additionally, IDQI was negatively associated with added sugar intake. No associations were observed between IDQI and saturated fat consumption. IDQI scores at age 1 were positively associated with the percentage of energy attributed to unprocessed/minimally processed foods (20%-23%) and negatively associated with UPF consumption at ages 2-5 y (-24% to -29%)., Conclusions: IDQI predicts intake of select nutrients and UPF consumption among low-income US children aged 2-5 y.This trial was registered at https://clinicaltrials.gov/study/NCT02031978 as "Feeding My Baby - A National WIC Study," NCT02031978., Competing Interests: The authors report no conflicts of interest., (© 2024 The Authors.)

Background: Children in the 6-23-mo age group need to consume adequate energy and nutrients for healthy growth, brain development, cognition, and future productivity. Yet, large deficits remain. Complementary feeding practices can be improved on a large scale, but whether interventions reach and benefit disadvantaged mothers is not known., Objectives: To assess inequalities in complementary feeding practices and coverage following large-scale program implementation in 3 low- and middle-income countries., Methods: We re-analyzed evaluation data from randomized controlled studies conducted in Bangladesh, Ethiopia, and Vietnam and calculated socioeconomic inequality using Erreygers index for intervention and nonintervention areas. Intervention coverage indicators were developed in each country for interpersonal communication, community mobilization, agricultural extension, and media. We compared the direction and magnitude of inequalities in intervention and nonintervention areas., Results: At the endline, coverage, and practices related to complementary feeding were better in intervention areas, but coverage and practices favored the better-off and more educated mothers. In Bangladesh, only 5, and in Vietnam, only 1 out of 16 coverage variables measured favored disadvantaged mothers or were neutral; in Ethiopia, out of 18 coverage variables measured, 11 favored disadvantaged mothers or were neutral, and in all 3 countries, only 5-6 variables out of 16 that were measured favored disadvantaged mothers or were neutral., Conclusions: Inequalities exist both in how children in the 6-23-mo age group are fed and in programs aimed at improving complementary feeding practices. Programs favor the better-off and more educated mothers. We need to better understand context-specific program barriers and tailor targeted interventions to reach disadvantaged mothers., Competing Interests: The authors report no conflicts of interest., (© 2024 The Authors.)

Background: Nongovernment food assistance is typically provided to families by faith-based organizations, schools, and food banks. Community organizations appear to be strongly committed to these programs, but little is known about the basis for this commitment., Objectives: The aim of this study was to examine the values and identities of community organizations to understand the reasons for their commitment to providing nongovernment food assistance., Methods: Thirty-three in-depth interviews were conducted with 36 leaders at faith-based organizations (19 participants), schools (14 participants), and a local food bank (3 participants) in South Carolina. Observations were made, and informational documents (e.g., flyers and pamphlets) were reviewed. Thematic coding using the constant comparative method was guided by the policy concepts of organizational perspectives, values, and identities., Results: Nongovernment food programs offered participants volunteering opportunities to become involved with community organizations, which in turn increased financial support for the sustainability of these programs. School participants regarded themselves as a mechanism through which food programs were provided because of their commitment to students and believed they have limited capacity to make proposals to influence the food programs. Seeking to improve the well-being of the community by ending hunger was not the primary value on which organizations focused; instead, it was the process of fulfilling other values (e.g., forming or maintaining relationships within the community), maintaining identity, and appealing to their participants that strengthened their commitment to nongovernment food programs., Conclusion: Nongovernment programs are meant to be a solution to food insecurity complementary to government programs. Commitment to nongovernment programs fulfills organizational identities, wants, and assumptions, but a consequence of commitment to food programs, derived from fulfilling other values, is that the roots of hunger in a community become obscured and alternative solutions are ignored or rejected., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Background: Consumption of unsafe foods increases morbidity and mortality and is currently an issue, particularly in low- and middle-income countries. Policy actions to ensure food safety are dominated by mitigation of biological and chemical hazards through supply-side risk management, lessening the degree to which consumer perspectives of food safety are considered., Objectives: This study aimed to provide an in-depth understanding, from vendor and consumer perspectives, of how food-safety concerns of consumers translate into their subsequent food-choice behaviors in 6 diverse low- and middle-income countries., Methods: Six Drivers of Food Choice projects (2016-2022) provided transcripts from 17 focus group discussions and 343 interviews conducted in Ghana, Guinea, India, Kenya, Tanzania, and Vietnam. Qualitative thematic analysis was used to identify emerging themes important to food safety., Results: The analysis suggests that consumers constructed meaning about food safety through personal lived experience and social influences. Community and family members contributed knowledge about food safety. Concerns about food safety were influenced by reputations of and relationships with food vendors. Consumers' mistrust of food vendors was amplified by purposeful adulteration or unsafe selling practices and new methods used to produce food. Moreover, consumers were reassured of food safety by positive relationships with vendors; meals cooked at home; implementation of policies and following regulations; vendor adherence to environmental sanitation and food-hygiene practices; cleanliness of vendors' appearance; and vendors' or producers' agency to use risk mitigation strategies in production, processing, and distribution of food., Conclusions: Consumers integrated their meanings, knowledge, and concerns about food safety to achieve assurance about the safety of their foods when making food-choice decisions. The success of food-safety policies hinges on consideration of consumers' food-safety concerns in their design and implementation, alongside actions to reduce risk in food supply., (© 2023 The Authors.)

Background: Assessing adolescents' experiences of food insecurity in households is important for promoting healthy development. Although parental reports have been traditionally used, emerging research highlights the importance of child and adolescent reports of the household food environment., Objectives: Extending research from high- and upper-middle-income countries, this study of adolescent compared with adult reports of household food insecurity in Kenya, a lower-middle-income country, examined 1 ) prevalence of and correspondence between adolescent and adult reports of household food insecurity, and 2 ) associations of adolescent and adult reports of household food insecurity with adolescent nonnutritional and nutritional outcomes., Methods: Using data from the Kenya Violence Against Children Surveys ( n  = 1182), we assessed prevalence of household food insecurity reported by adolescents (ages 13-17 y) and adults, with McNemar χ 2 and κ analysis of correspondence between reports. Ordinal and binary logistic regression assessed associations between adolescent and adult reports and adolescent mental health and self-rated physical health and food sufficiency outcomes., Results: Household food insecurity was reported by 36% of adolescents and 63% of adults; 36% of adult reports were discordant with adolescent reports (κ = 0.333). Odds of adolescent mental health difficulties were highest with adolescent-only report (OR = 2.11, P  = 0.02), followed by adult and adolescent (OR = 1.83, P  = 0.001) and adult-only (OR = 1.06, P  = 0.77) report. Odds of poor adolescent self-rated physical health were highest with adult and adolescent report (OR = 2.47, P  < 0.001) followed by adolescent-only (OR = 2.04, P  = 0.08) and adult-only (OR = 1.37, P  = 0.20) report. Odds of adolescents eating ≤1 meals the previous day were highest with adult and adolescent (OR = 21.38, P  < 0.001) followed by adult-only (OR = 7.44, P  = 0.01) and adolescent-only (OR = 2.31, P  = 0.34) report., Conclusions: Measuring household food insecurity with both adolescent report and adult report is important for having a comprehensive understanding of household resources and needs and of the nonnutritional (mental and physical health) and nutritional (diet and food) outcomes of household food insecurity for adolescents., (© The Author(s) 2022.

Background: Adolescents' developmental tasks and challenges vary based on age, sex, and social context. Food insecurity affects adolescents, but existing research has been limited to a few country contexts and has treated adolescence as a singular developmental moment with limited consideration of potential differences in how food insecurity relates to developmental experiences based on adolescent age and sex., Objectives: We aimed to describe relations between student-reported food insecurity and students' profiles of nutritional, physical activity, school absenteeism, health/mental health, and victimization experiences, and how these differ by student age and sex., Methods: Using cross-sectional data from the Global School-based Student Health Survey, we examined adolescent reports of their food security among 337,738 students 11-18 y old from 95 countries. We identified their profiles of focal experiences, and used mixed-effects linear and logistic regression models to examine differences in these profiles by student food insecurity and how these differ by student age and sex., Results: Of students, 25.5% aged 11-14 y compared with 30% aged 15-18 y reported food insecurity in the past 30 d. Food insecurity was associated with less frequent fruit and vegetable intake; more frequent soft drink intake; worse mental health; less physical activity; more missed school; higher odds of smoking, drinking, and using drugs; and more bullying victimization and sexual partners. Food insecurity was associated with reduced age- and sex-specific protection: greater substance use among younger adolescents, more sexual partners among older females, and greater worry among younger males. Food insecurity was also associated with increased age-specific risk: greater soft drink consumption among younger adolescents., Conclusions: Across countries, adolescent food insecurity was associated with poorer nutritional, mental health, behavioral, and relationship profiles; these associations differed with student age and sex. Food insecurity interventions should attend to adolescent developmental stage and the gendered contexts through which adolescents navigate daily life., (© The Author(s) 2022.

Information on the prevalence of micronutrient deficiencies is needed to determine related disease burden; underpin evidence-based advocacy; and design, deliver, and monitor safe, effective interventions. Assessing the global prevalence of deficiency requires a valid micronutrient status biomarker with an appropriate cutoff to define deficiency and relevant data from representative surveys across multiple locations and years. The Global Burden of Disease Study includes prevalence estimates for iodine, iron, zinc, and vitamin A deficiencies, for which recommended biomarkers and appropriate deficiency cutoffs exist. Because representative survey data are lacking, only retinol concentration is used to model vitamin A deficiency, and proxy indicators are used for the other micronutrients (goiter for iodine, hemoglobin for iron, and dietary food adequacy for zinc). Because of data limitations, complex statistical modeling is required to produce current estimates, relying on assumptions and proxies that likely understate the extent of micronutrient deficiencies and the consequent global health burden., (© The Author(s) 2021.

Models are needed for how to advance use of knowledge by programs and policy officials to make evidence-based decisions about nutrition. How to advance use of nutrition knowledge in India from 2011 to 2015 during a political transition was investigated through studying a knowledge initiative led by the International Food Policy Research Institute. Semistructured interviews were conducted with 37 diverse participants, and 1091 news articles, 318 Twitter and 175 Facebook posts, 12 YouTube events, 65 knowledge products, and 130 engaging events were assessed. Open-axial coding, content and themes analysis, triangulation, and process tracing were used. The knowledge initiative analyzed the landscape, made knowledge available, mobilized it, and engendered its use. After political transition, knowledge was readied for the reassembled nutrition technical community, including timely responses to governmental information needs. Making nutrition knowledge available, mobilizing it, and engendering its use can be advanced through knowledge initiatives in large, complex countries during political transitions., (© The Author(s) 2021.

Background: Presidents with no possibility of re-election overvalue far-future rewards and succumb to terminal logic behavior (TLB), responding to end-of-tenure legacy concerns despite political context. Government authorities perceiving the outgoing government is losing power at the end of term behave under the logic of strategic defection (SD), dissociating from the outgoing government once it is perceived powerless. In countries where re-election is impossible and government turnover and inconstant political parties are concerns, governmental officials at all levels may show TLB and SD during transitions that affect policy sustainability., Objectives: This study aimed to understand the context during presidential transitions that makes TLB and SD relevant, whether TLB and SD affect sustainability of food and nutrition security policy (FNSP), and the tactics for navigating transitions that favor sustainability., Methods: A case-study design was used with semi-structured qualitative interviews and document review of news articles in Guatemala. Purposeful criteria and snowball sampling were used to recruit 52 policy actors implementing an FNSP across 2 transitions; 252 news articles from the referenced period covering topics on policy programmatic areas were purposefully sampled. Interviews were analyzed using coding and thematic analyses. News articles were analyzed using a priori thematic coding for verifying themes in interviews and data triangulation., Results: Governmental officials were replaced by others during transitions; political parties were perceived as inconstant. TLB and SD occurred at all levels and had consequences for sustainability of FNSP: implementation slow-down, dysfunctional collaboration, inefficient use of resources, benefits not reaching targeted groups, and loss of momentum. These occurred through individual, institutional, and political mechanisms. Civil society, international organizations, and government adopted tactics for maximizing sustainability., Conclusions: Understanding governmental officials' experiences and the extent to which TLB and SD occur and affect sustainability could be advantageous to develop compensatory actions for reaching long-term FNSP goals., (© The Author(s) 2020.

Background: Child undernutrition in India remains widespread. Data from the National Family Health Survey 3 and 4 (NFHS-3 and NFHS-4) suggest that wasting prevalence has increased while stunting prevalence has declined., Objective: The objectives of this study were to do the following: 1 ) describe wasting and stunting by month of measurement in India in children <5 y of age in NFHS-3 and NFHS-4 surveys, and 2 ) test whether differences in the timing of anthropometric data collection and in states between survey years introduced bias in the comparison of estimates of wasting and stunting between NFHS-3 and NFHS-4., Methods: Data on wasting and stunting for 42,608 and 232,744 children aged >5 y in the NFHS-3 and NFHS-4 survey rounds were analyzed. Differences in the prevalence of wasting and stunting by month of year and by state of residence were examined descriptively. Regression analyses were conducted to test the sensitivity of the estimate of differences in wasting and stunting prevalence across survey years to both state differences and seasonality., Results: Examination of the patterns of wasting and stunting by month of measurement and by state across survey years reveal marked variability. When both state and month were adjusted, regardless of the method used to account for sample size, there was a small negative difference from 2005-2006 to 2015-2016 in the prevalence of wasting (-0.8 ± 0.6 percentage points; P  = 0.2) and a negative difference in stunting prevalence (-8.3 ± 0.7 percentage points; P < 0.001), indicating a small bias for wasting but not for stunting in unadjusted analyses., Conclusions: State and seasonal differences may have introduced bias to the estimated difference in prevalence of wasting between the survey years but did not do so for stunting. Future data collection should be designed to maximize consistency in coverage of both time and place., (Copyright © The Author(s) on behalf of the American Society for Nutrition 2020.)

We tested whether a multisectoral household agricultural and finance intervention increased the dietary intake and improved the nutritional status of HIV-affected children. Two hospitals in rural Kenya were randomly assigned to be either the intervention or the control arm. The intervention comprised a human-powered water pump, microfinance loan for farm commodities, and training in sustainable farming practices and financial management. In each arm, 100 children (0-59 mo of age) were enrolled from households with HIV-infected adults 18-49 y old. Children were assessed beginning in April 2012 and every 3 mo for 1 y for dietary intake and anthropometry. Children in the intervention arm had a larger increase in weight (β: 0.025 kg/mo, P  = 0.030), overall frequency of food consumption (β: 0.610 times · wk -1 · mo -1 , P  = 0.048), and intakes of staples (β: 0.222, P  = 0.024), fruits and vegetables (β: 0.425, P  = 0.005), meat (β: 0.074, P  < 0.001), and fat (β: 0.057, P  = 0.041). Livelihood interventions have potential to improve the nutrition of HIV-affected children. This trial was registered at clinicaltrials.gov as NCT01548599., (Copyright © The Author(s) 2020.)

Background: Social and behavior change communication interventions are integral to improving dietary and care practices, but evidence on the impact of the combination and intensity of these interventions in different contexts is scarce., Objectives: We examined the extent of and factors associated with intervention exposure: interpersonal communication (IPC) alone or with other interventions (i.e., mass media, community mobilization, or nutrition-sensitive agricultural activities), number of and factors associated with IPC contacts, and combinations of intervention components and number of contacts associated with infant and young child feeding (IYCF) practices., Methods: We used endline survey data from impact evaluations in Bangladesh, Ethiopia, and Vietnam ( n  = 1001, 1720, and 1001 mothers with children aged <2 y, respectively). Multivariable regression models were used for analyses., Results: Exposure to the interventions varied in all 3 countries. On average, mothers received 8 visits in the last 6 mo in Bangladesh, 2 visits in the last 3 mo in Ethiopia, and 1 visit in the last 6 mo in Vietnam. Across countries, the factors associated with intervention exposure and number of IPC contacts differed. In Ethiopia, exposure to IPC with other interventions was associated with higher odds of achieving minimum meal frequency (OR: 1.6), minimum dietary diversity (OR: 1.8), and consumption of iron-rich foods (OR: 4.7). In Vietnam, exposure to IPC alone or with mass media was associated with higher odds of exclusive breastfeeding (EBF; OR: 2.8-3.7). Near-monthly visits were associated with 2-3 times higher odds of IYCF practices in Bangladesh and Ethiopia. In Vietnam, even 1 IPC visit was associated with 2 times higher odds of EBF., Conclusions: Exposure matters for impact, but the combination of behavior change interventions and number of IPC contacts required to support IYCF behavior change are context specific. This trial was registered at www.clinicaltrials.gov as NCT01678716 (Bangladesh), NCT02775552 (Ethiopia), and NCT01676623 (Vietnam)., (Copyright © The Author(s) 2019.)

Background: Frontline health workers (FLWs) are needed for delivering interventions at scale to reduce maternal and child undernutrition, but low- and middle-income countries often face inadequate FLW performance., Objectives: We examined whether and how intervention design elements such as training, supervision, and mass media improved FLW performance in delivering nutrition services., Methods: Survey data were collected in 2010 and 2014 as part of impact evaluations of Alive & Thrive (A&T) interventions to improve infant and young child feeding (IYCF) practices in Bangladesh and Vietnam. FLWs in A&T intensive (A&T-I) areas received specialized IYCF training, job aids, and regular supportive supervision. Those in non-intensive (A&T-NI) areas received standard government training and supervision. There was mass media exposure in both areas. Multiple regression was used to test differences in exposure to intervention design elements and performance outcomes between the 2 program areas. Path analyses were conducted to examine the paths from exposure to performance outcomes measured at FLW and end-user levels., Results: Compared to FLWs in A&T-NI areas, those in A&T-I areas had higher scores in training (by 1.3-3.6 of 10 points), supportive supervision (0.3-3.5 points), and mass media exposure (0.3-3.5 points). These intervention design elements were significantly associated with FLW knowledge and motivation, which in turn improved service delivery. FLW-level performance outcomes contributed to improving end-user-level outcomes such as higher service received (β = 0.12-1.04 in Bangladesh and 0.11-0.96 in Vietnam) and maternal knowledge (β = 0.12-0.17 in Bangladesh and 0.04-0.21 in Vietnam)., Conclusions: Training, supervision, and mass media exposure can be implemented at large scale and contribute to improved FLW service delivery by enhancing knowledge and motivation, which in turn positively influence mother's service utilization and IYCF knowledge. Training, supervision, and mass media to enhance service provision should be considered when designing interventions. This trial was registered at clinicaltrials.gov as NCT01678716 (Bangladesh) and NCT01676623 (Vietnam).
