Household food insecurity and early childhood development: Systematic review and meta-analysis

Community-based diet and obesity-related policy, system, and environmental interventions for obesity prevention during the first 1000 days: A scoping review

Community-based policy, systems, and environmental interventions have the potential to reduce modifiable risk factors for obesity early in life. The purpose of this scoping review was to characterize the breadth, generalizability, and methodological quality of community-based diet and obesity-related policy, system, and environmental interventions during the first 1000 days of life, from pregnancy to 24 months of age. Eight databases were searched, and 83 studies (122 references) were included. Data were extracted for breadth (intervention characteristics), generalizability (reach, effectiveness, adoption, implementation, and maintenance), and study quality (Downs and Black Checklist). Systems and environmental approaches were common (> 80%), relative to policy approaches (39%). The majority (60-69%) occurred in the prenatal period and early infancy (0-3 months), assessed breastfeeding or child growth/obesity (53% for both), and included people with lower income (80%) or racial and/or ethnic minority groups (63%). Many interventions reported positive outcomes (i.e., in the expected direction) for child diet, breastfeeding, and feeding practices (> 62%). Few reported intervention maintenance or spanned the full 1000 days. Most studies were classified as good (32%) or fair (56%) methodological quality. The interventions mainly addressed pregnancy and early infancy. Rigorous and representative investigation is needed to improve intervention reach, sustainability, and application in toddlerhood.

Acceptability of Pilot School-based Food Pantries Compared With Weekend Feeding BackPack Programs Among Food Pantry Clients in Rural Tennessee: A Mixed-Methods Approach

OBJECTIVE

To explore the client acceptability and perceived impact of pilot school-based food pantries (SBFPs) and compare client preference between SBFPs and BackPack programs (locally termed Sack Pack) in 3 rural Tennessee elementary schools.

METHODS

A mixed-method design, including cross-sectional surveys (n = 25) and semistructured interviews (n = 11), was used to assess and compare program acceptability.

RESULTS

Client satisfaction was uniformly positive for both programs; however, a majority preferred the food quantity (84%), nutritional value (76%), variety (68%), quality (68%), and convenience (64%) of SBFPs. Clients reported feeding more household members with SBFPs (3.9 ± 0.9 vs 3.0 ± 1.0) compared with Sack Pack. When exploring SBFPs vs Sack Pack, 3 primary themes emerged from interviews and were supported by survey data: preferences for different program elements; food acceptability; and SBFP impact and expansion.

CONCLUSIONS AND IMPLICATIONS

Findings support continuing SBFPs in rural schools. Studies on expanding the use of trusted and accessible schools as potential healthful food distribution sites are warranted to support broader community food access in rural areas.

Using concept mapping to co-create implementation strategies to address maternal-child food insecurity during the first 1000 days of life

Food insecurity (FI) has short- and long-term effects on maternal and child health, with persistent inequities within under-resourced communities of colour (e.g., Hispanic and Non-Hispanic Black). Interventions to mitigate maternal-child FI must engage the voices of under-resourced communities of colour to improve implementation and tackle socio-ecological drivers of inequities, leading to positive maternal-child outcomes. This exploratory sequential mixed-methods study aimed to co-create implementation strategies to tailor a culturally sensitive intervention to address FI during the first 1000 days of life in under-resourced communities of colour in Las Vegas. A Community Advisory Board (CAB) engaged in a two-step participatory process. First, through the concept mapping, hierarchical cluster analysis organized 125 strategies into seven thematic areas: policy and advocacy, access to food and resources, built environment, education across systems, social and peer support, cultural congruency and trust, and wellness and mental health. Second, through consensus-building, strategies were combined by similarity (n = 94) and excluded if unrelated to health and nutrition (n = 9). The CAB reached a consensus on 22 strategies classified across three socio-ecological levels. Examples of strategies at the community level (n = 16) included increasing utilization of federal nutrition assistance programmes; at the service level (n = 4), integrating FI screenings and referral coordination systems across services; and at the individual level (n = 2), providing mentorship, education, and support for families and moms. The co-creation of a culturally sensitive intervention to reduce inequities in maternal-child FI during the first 1000 days of life requires multi-level strategies across three socio-ecological levels in under-resourced communities of colour in Las Vegas.

Revising a right to food road map-perspectives of Australian key informants

OBJECTIVE

In Australia, an estimated 1 in 10 households experiences food insecurity. The objective of this study was to devise a visual synthesis to summarise the activities, processes and principles that support the right to food for everyone in Australia.

METHODS

Semi-structured key informant interviews (n=30) were conducted during 2019-20. Content analysis synthesised perspectives and assisted co-authors in revising an initial draft (shared during the interview) to finalise the road map through semantic realist data analysis and re-design.

RESULTS

The six components of the right to food road map summarise the actions, processes, and principles to address the human right to food. These include i) policy leadership, ii) advocate and enact, iii) empowerment, iv) resourcing, v) monitoring and accountability and vi) healthy, equitable and sustainable food systems.

CONCLUSIONS

When all the right to food actions, processes and principles are present, the "cogs" within the map are hypothesised to interact and realise the right to food for all Australians.

IMPLICATIONS FOR PUBLIC HEALTH

Considering the cost of living pressures and unrelenting demand for food relief, better solutions are needed for food insecurity. Human rights - this language, their international recognition and as a "method of working", offer an alternative to the dominant responses to food insecurity.

Micronutrient Consumption Among Postpartum Women and Food Insecurity

This study aimed to assess the prevalence of inadequate micronutrient intake and its risk factors among women one year after giving birth. 240 women of reproductive age were assessed. Micronutrient intake was assessed from two 24-hour records at three stages (3-6-12 months after childbirth). A generalized linear mixed-effect model was used to assess the factors associated with food intake. A prevalence of inadequate micronutrient intake was observed, with the exception of iron. Intake was lower among food-insecure women (zinc: β -0.13; iron: β -0.09; vitamin C: β -0.44). The postpartum period and food insecurity remained statistically associated with lower food consumption in the explanatory models tested.

Complex intertwined association between breastfeeding practices and household food insecurity: Systematic review and meta-analysis

Breastfeeding offers ideal food and nutrition for infants; however, structural barriers may amplify breastfeeding inequities. We aimed to identify whether household food insecurity (HFI) is associated with exclusive and continued breastfeeding (EBF and CBF) as recommended by the World Health Organization/United Nations Children's Fund (UNICEF) Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, literature searches using 'breastfeeding', 'food insecurity' and 'infant' terms were conducted in PubMed/MEDLINE, Embase, CINAHL, Global Health and LILACS from inception through November 2023, without language restrictions, yielding 1382 publications (PROSPERO:CRD42022329836). Predetermined eligibility criteria yielded the 12 included studies (nine cross-sectional and three cohorts). The risk of bias was assessed through the Effective Public Health Practice Project. Meta-analysis was performed for studies assessing EBF (n = 10), and metaregression was used to explore heterogeneity across studies. Prevalence of EBF ranged from 1.6% to 85.3%, with a lower prevalence among HFI. The pooled effect of the association between HFI and EBF presented an odds ratio (OR) of 0.61 (95% CI = 0.49-0.76) with consistent results across marginal (OR = 0.72, 95% CI = 0.55-0.94), moderate (OR = 0.59, 95% CI = 0.41-0.84) and severe HFI (OR = 0.49, 95% CI = 0.32-0.76). High heterogeneity was found only when HFI was dichotomized. The prevalence of CBF ranged from 35.4% to 78.0%, with inconsistent prevalence among HFI; a meta-analysis was not performed due to the low number of studies (n = 3). We concluded that HFI levels are associated with lower odds of EBF. Integrating service and policy-level strategies, such as screening, referrals, skilled breastfeeding counseling and access to comprehensive nutrition and social programs, could reduce structural inequities and promote adherence to the World Health Organization/UNICEF breastfeeding recommendations among food-insecure families.

Nurturing care assets for food security: a community asset mapping approach

BACKGROUND

Zip codes classified by the Food Insecurity Index with moderate and high food insecurity (FI) risk can be a threat to the health and well-being of children during the first 1,000 days (from pregnancy to 2 years). The presence of nurturing care assets (i.e., stable environments that promote health and nutrition, learning opportunities, security and safety, and responsive relationships) can contribute to supporting families and their communities, and ultimately reduce systemic barriers to food security. We aimed to identify and characterize nurturing care assets in under-resourced communities with moderate and high FI risk.

METHODS

Four steps were used to conduct a Community Asset Mapping (CAM): (1) review of community documents across five zip codes in Clark County, Nevada (2), engagement of community members in identifying community assets (3), definition of the assets providing nurturing care services, and (4) classification of assets to nurturing care components, i.e., good health, adequate nutrition, safety and security, opportunities for early learning, and responsive caregiving. The Food Insecurity Index was used to determine FI risk in each zip code. Analyses explored whether disparities in nurturing care assets across zip codes with moderate and high FI exist.

RESULTS

We identified 353 nurturing care assets across zip codes. A more significant number of nurturing care assets were present in zip codes with high FI risk. The adequate nutrition component had the most assets overall (n = 218, 61.8%), while the responsive caregiving category had the least (n = 26, 7.4%). Most of the adequate nutrition resources consisted of convenience stores (n = 96), food pantries (n = 33), and grocery stores (n = 33). Disparities in the number and type of good health, early learning, and security and safety assets were identified within zip codes with high FI risk compared to moderate FI risk.

CONCLUSIONS

The quantity and type of nurturing care assets can exacerbate existing demographic disparities across zip codes, which are tied to barriers to access to food in under-resourced communities in Clark County, Nevada. Co-creating a nurturing care asset-based zip code strategy to address high FI risk will require strengthening systems across existing nurturing care assets.

Food Insecurity Screening in High-Income Countries, Tool Validity, and Implementation: A Scoping Review

Household food insecurity has significant negative implications across the lifespan. While routine screening is recommended, particularly in healthcare, guidelines are lacking on selection of screening tools and best-practice implementation across different contexts in non-stigmatizing ways. The objective of this scoping review was to synthesize evidence on household food insecurity screening tools, including psychometrics, implementation in a range of settings, and experiences of carrying out screening or being screened. Four electronic databases were searched for studies in English published from 1990 until June 2023. A total of 58 papers were included, 21 of which focused on tool development and validation, and 37 papers described implementation and perceptions of screening. Most papers were from the USA and described screening in healthcare settings. There was a lack of evidence regarding screening in settings utilized by Indigenous people. The two-item Hunger Vital Sign emerged as the most used and most valid tool across settings. While there is minimal discomfort associated with screening, screening rates in practice are still low. Barriers and facilitators of screening were identified at the setting, system, provider, and recipient level and were mapped onto the COM-B model of behavior change. This review identifies practical strategies to optimize screening and disclosure.

Caregiver Preferences for Primary Care Clinic-Based Food Assistance: A Discrete Choice Experiment

OBJECTIVE

The American Academy of Pediatrics recommends that pediatric providers screen families for food insecurity and connect them to appropriate resources. However, it is unclear how clinics can best provide families with resources consistent with their needs and preferences. In this study, we elicited caregiver preferences for clinic-based food assistance.

METHODS

We conducted a cross-sectional discrete choice experiment in which caregivers at 2 pediatric primary care clinics were asked to choose between hypothetical food programs. Programs varied across 4 categories: 1) resources provided (eg, food delivery, food in clinic, assistance enrolling in benefits); 2) support staff providing resources (eg, social worker, community health worker, physician, or nurse); 3) outreach modality (eg, phone, email, text); and 4) outreach frequency. Multinomial logistic regression was used to assess caregiver preferences within each category and the relative importance of each category to caregiver decisions.

RESULTS

We surveyed 142 caregivers who were predominantly Black (87%) and Medicaid-insured (90%). Caregiver preferences for food programs were most strongly influenced by the food resources provided. Caregivers preferred food delivery over other forms of food supports, such as food provided in clinic. They preferred assistance from a benefits enrollment specialist, community health worker, or social worker to assistance from a physician or nurse.

CONCLUSIONS

Pediatric clinics serving families at risk of food insecurity should use caregiver preferences to inform the design of family-centered interventions. Clinics should consider connecting caregivers with food delivery programs, and pediatric payors should adopt reimbursement models that support multidisciplinary team-based care to address food insecurity.

Lower Perceived Neighborhood Collective Efficacy Indirectly Influences the Association Between Perceived Maternal Exposure to Community Violence and Household Food Insecurity

BACKGROUND AND OBJECTIVES

Individuals of color and of low socioeconomic status are at greater risk of experiencing community violence and food insecurity, which are both influenced by neighborhood conditions. We evaluated neighborhood collective efficacy as a linkage between community violence exposure and household food insecurity.

METHODS

Mothers from the Future of Families and Child Wellbeing Study who completed phone surveys when the child was 3 (time 1, T1) and 5 years old (time 2, T2) were included (n = 2068). A covariate-adjusted structural equation model estimated direct and indirect effects of community violence exposure on household food insecurity. A covariate-adjusted multiple mediator model estimated the indirect effects of the 2 neighborhood collective efficacy subscales (informal social control; social cohesion and trust).

RESULTS

At T1, 40% of mothers reported community violence exposure; 15% experienced food insecurity at T2. Mean neighborhood collective efficacy (range 1-5) at T1 was 2.44 (SD = 0.94). Neighborhood collective efficacy indirectly influenced the association between community violence exposure and food insecurity (indirect effect = 0.022, 95% CI = 0.007 to 0.040). Only social cohesion and trust contributed independent variance to the indirect effect model (indirect effect = 0.028, 95% CI = 0.001 to 0.056).

CONCLUSIONS

Community-based efforts to reduce household food insecurity should emphasize building social cohesion and trust in communities experiencing violence.

Association between household food insecurity and stunting in children aged 0-59 months: Systematic review and meta-analysis of cohort studies

Household food insecurity (HFI) during childhood is associated with poor dietary diversity and malnutrition, placing children's growth at risk. Children with growth disorders, such as stunting, are more likely to have poor cognition and educational performance, lower economic status, and an increased risk of nutrition-related chronic diseases in adulthood. Our study aimed to systematically review and conduct a meta-analysis of cohort studies investigating the association between HFI and stunting in children aged 0-59 months. Peer-reviewed and grey literature were systematically searched in electronic databases with no language or date restrictions. Two reviewers independently assessed the studies for pre-established eligibility criteria. Data were extracted using a standard protocol. Random-effects meta-analysis models were used, and I2 > 40% indicated high heterogeneity across studies. We used the Grading of Recommendations Assessment, Development, and Evaluation system to assess the quality of the evidence. Nine cohort studies comprising 46,300 children were included. Approximately 80% (n = 7) of the studies found a positive association between HFI and stunting. Pooled odds ratio was 1.00 (95% confidence interval [CI]: 0.87-1.14; I2: 76.14%). The pooled hazard ratio between moderate and severe HFI and stunting was 1.02 (95% CI: 0.84-1.22; I2: 85.96%). Due to high heterogeneity, the quality of evidence was very low. Individual studies showed an association between HFI and stunting in children aged 0-59 months; however, this association was not sustained in the pooled analysis, possibly because of high heterogeneity across studies.

Positive Early Childhood Experiences and School Readiness among US Preschoolers

OBJECTIVES

To characterize the relationship between positive early childhood experiences (PECEs) and school readiness, and assess whether the PECEs-school readiness relationship was robust to and/or differed across levels of adverse childhood experiences (ACEs).

METHODS

We analyzed national data on children ages 3-5 from 2016 to 2020 (n = 26 871) to examine associations between key PECE domains (nurturing relationships, home learning opportunities, safe and stable environments, and family routines) with being on track for school readiness, defined using a pilot, multidimensional measure called "healthy and ready to learn". Weighted univariate, bivariate, and multivariable analyses were conducted to generate nationally representative estimates. Multivariable models adjusted for sociodemographic factors and were assessed both with and without cumulative ACE exposure.

RESULTS

Two-fifths of children were healthy and ready to learn. Exposure to PECEs was associated with higher school readiness, irrespective of relative ACE exposure. Compared with those with low PECEs, children with moderate (aOR, 2.19; 95% CI, 1.86-2.58) and high (aOR, 4.37; 95% CI, 3.58-5.34) PECEs had greater odds for being healthy and ready to learn, net of both sociodemographic factors and ACE exposure. Significant associations were robust across demographic groups (eg, race and ethnicity), ACE levels, and ACE types (eg, parental incarceration).

CONCLUSIONS

Increasing PECEs correspond with greater likelihood of possessing capacities key for school functioning, even amidst ACEs. In concert with efforts to ameliorate early life trauma, caregivers, health care providers, educators, and systems can consider boosting PECEs to foster healthy development in childhood and beyond.

Mealtimes in the context of poverty: Comparison of ECEC services providing food and those requiring food provided from home

BACKGROUND

In developed economies, most children attend Early Childhood Education and Care (ECEC) services before school entry, many from early life and across long days. For this reason, ECEC services present significant potential to provide food environments that positively influence eating behaviours and food preferences with attendant effect on life course trajectories of health and wellbeing. Yet there is evidence that feeding practices that limit optimal ongoing nutrition, such as pressure and restriction, are amplified in ECEC services serving disadvantaged communities. We sought to identify underlying explanatory mechanisms through observation of children's feeding experiences and educator explanations comparing, family-provided and service-provided meals.

METHOD

This study used qualitative analyses of educator interviews and observation records from 55 mealtimes in 10 ECEC services: 5 providing food and 5 requiring family food provision.

RESULTS

High levels of concern drove educator's controlling feeding practices at mealtimes but presented differently across meal provision modes. In centres that provided food, educators' concern focused on food variety, manifesting in pressure to 'try' foods. In centres requiring family-provided food, concern focused on nutrition quantity and quality and manifested as control of order of food consumption and pacing of intake to ensure food lasted across the day. Interview data suggested that conflict aversion limited optimal nutrition. In centres providing food, this was seen in menus that prioritized child food preferences. In centres requiring family meal provision, conflict aversion was seen as reticence to discuss lunchbox contents with families.

CONCLUSION

The findings direct attention to public health intervention. Currently, ECEC face significant barriers to realizing their potential to support child nutrition and establish positive life course trajectories of nutrition. To do so requires targeted supports that enable sufficient supply and quality of food in the context of poverty.

Association of household food insecurity with developmental delay in preschool children: 2018 Ecuadorian Nutrition and Health National Survey

We investigated the association of household food insecurity (HFI) with developmental delays in 36-59-month-old preschool children (n 7005) using cross-sectional data from the 2018 Ecuadorian National Health and Nutrition Survey. HFI was assessed with the Food Insecurity Experience Scale and developmental delays with the Early Childhood Development Index. Log-binomial regression models estimated the association of HFI with global (overall) developmental delay (GDD) and delays in four individual developmental domains, adjusting for covariates. Nearly half of the children lived in households with marginal (24⋅5 %) or moderate-severe HFI (21⋅7 %). Eighteen percent were identified with GDD. Delays in the individual domains of literacy-numeracy, social-emotional, physical and cognitive development were identified for 64, 21⋅5, 3⋅3 and 3⋅1 %, respectively. GDD was more likely among preschool children from households with marginal (aPR = 1⋅29; 95 % C.I. = 1⋅10, 1⋅49) and moderate-severe HFI (aPR = 1⋅30; 95 % C.I. = 1⋅11, 1⋅51). Social-emotional development delays were also more likely among those from households with marginal (aPR = 1⋅36; 95 % C.I. = 1⋅19, 1⋅56) and moderate-severe HFI (aPR = 1⋅33; 95 % C.I. = 1⋅15, 1⋅54) different from the other three domains. Several other potentially modifiable risk (violent discipline, maternal depressive symptoms) and protective factors (adequate child stimulation, higher maternal education, handwashing with soap/detergent) were also independently associated with GDD and/or literacy-numeracy and cognitive delays. Our findings suggest that HFI is an independent risk factor for GDD and social-emotional developmental delays in Ecuadorian preschoolers. They underscore the importance of strengthening and expanding poverty reduction, food security and early childhood development policies and interventions to improve the opportunities for children to achieve their full developmental potential.

Cross-Sector Intervention Strategies to Target Childhood Food Insecurity in North Carolina

BACKGROUND

Childhood food insecurity increased considerably during the COVID-19 pandemic and is associated with compromised health. Health care systems are increasingly prioritizing food insecurity interventions to improve health, but it is unclear how health systems collaborate with other sectors that are addressing food insecurity. In this study, we aimed to evaluate existing collaborations and explore opportunities for further cross-sector engagement.

METHODS

From December 2020 to March 2021, we conducted semi-structured interviews (N = 34) with informants involved in increasing child food access in North Carolina. Our informants represented different sectors, including community (e.g., food pantry), education (e.g., school lunch program), and government (e.g., Supplemental Nutrition Assistance Program). Rapid qualitative analysis was used to interpret the results and identify themes.

RESULTS

Informants rarely mentioned the health care sector as a source of referrals or as a collaborator. Barriers limiting access to food insecurity programs were exacerbated by the COVID-19 pandemic, including lack of transportation, stigma deterring use, limited food choice, and burdensome enrollment processes. Stakeholders recommended mitigating barriers through the expansion of food delivery, colocalization of assistance programs in schools and health care settings, increased food choice, and supporting cross-program enrollment mechanisms.

LIMITATIONS

The majority of the stakeholders represented programs from five counties in central North Carolina, with only a few representing statewide initiatives.

CONCLUSIONS

The COVID-19 pandemic both highlighted the fragmented system of food insecurity organizations and accelerated development of cross-sector collaborations to reduce access barriers. Health care systems are siloed from school and community efforts but have the opportunity to leverage ongoing innovative policy initiatives to construct novel cross-sector models. Such models can better link food insecurity screening with community-based solutions to address family-level food access barriers.

Household food insecurity is prevalent in a cohort of postpartum women who registered in the Canada Prenatal Nutrition Program in Toronto

OBJECTIVE

To assess the prevalence, severity and socio-demographic predictors of household food insecurity among vulnerable women accessing the Canada Prenatal Nutrition Program (CPNP) and to examine associations between household food insecurity and breastfeeding practices to 6 months.

DESIGN

Cohort investigation pooling data from two studies which administered the 18-item Household Food Security Survey Module at 6 months postpartum and collected prospective infant feeding data at 2 weeks and 2, 4 and 6 months. Household food insecurity was classified as none, marginal, moderate or severe. Logistic regression analyses were performed to assess predictors of household food insecurity and associations between household food security (any and severity) and continued and exclusive breastfeeding.

SETTING

Three Toronto sites of the CPNP, a federal initiative targeting socially and/or economically vulnerable women.

PARTICIPANTS

316 birth mothers registered prenatally in the CPNP from 2017 to 2020.

RESULTS

Household food insecurity at 6 months postpartum was highly prevalent (44 %), including 11 % in the severe category. Risk of household food insecurity varied by CPNP site (P < 0·001) and was higher among multiparous participants (OR 2·08; 95 % CI 1·28, 3·39). There was no association between the prevalence or severity of food insecurity and continued or exclusive breastfeeding to 6 months postpartum in the adjusted analyses.

CONCLUSIONS

Household food insecurity affected nearly half of this cohort of women accessing the CPNP. Further research is needed on household food insecurity across the national CPNP and other similar programmes, with consideration of the implications for programme design, service delivery and policy responses.

Predictors of Food Insecurity and Childhood Hunger in the Bronx During the COVID-19 Pandemic

Using a community-based participatory research approach, we conducted a survey of 218 food pantry recipients in the south Bronx to determine predictors of food insecurity and childhood hunger. In adjusted multiple regression models, statistically significant risk factors for food insecurity included: having one or more children and not having health insurance. Statistically significant protectors against childhood hunger were: having a graduate degree, having health insurance and Spanish being spoken at home. Experiencing depression symptoms was positively associated with both food insecurity and childhood hunger. Frequency of food pantry use was not significantly associated with either food insecurity nor childhood hunger. This study suggests that targeting families with multiple children and without insurance will best help to promote food security among residents of the south Bronx. Social policy implications related to food security and benefit provision through the COVID-19 pandemic are also provided.

Risks to Child Development and School Readiness Among Children Under Six in Pakistan: Findings from a Nationally Representative Phone Survey

This paper analyzes the risks to child development and school readiness among children under age 6 in Pakistan. Drawing on a nationally representative telephone survey conducted in the midst of a global pandemic, between December 2021 and February 2022, we present the first nationally representative estimates of child development for children under 3 years of age and school readiness for children 3-6 years of age, using internationally validated instruments. The paper examines how risk factors that were exacerbated due to the COVID-19 pandemic, such as parental distress, lack of psychosocial stimulation, food insecurity, low maternal education, no enrollment in early childhood education, and living in a rural area, are associated with children's outcomes. The data indicate that more than half (57 percent) of parents with children under age 3 were distressed and that 61 percent of households reported cutting down on the size of or skipping meals since the start of the pandemic. The data reveal that over half of parents fail to engage in adequate psychosocial stimulation with their child and enrollment in early childhood education is very low (39 percent). The paper finds that child development outcomes decline rapidly as the number of risks increase. Specifically, for children under 3 years, lack of psychosocial stimulation at home and higher levels of parental distress were most significantly associated with lower child development levels. For a child aged 3-6 years, early childhood education enrollment and the amount of psychosocial stimulation the child received at home had the strongest association with school readiness scores.

Creating a culture that supports food security and health equity at higher education institutions

Food insecurity on college campuses is a major public health problem and has been documented for the last decade. Sufficient food access is a crucial social determinant of health, thus campuses across the country have implemented various programmes, systems and policies to enhance access to food which have included food pantries, campus gardens, farmers' markets, meal share or voucher programmes, mobile food applications, campus food gleaning, food recovery efforts, meal deliveries and task force/working groups. However, little is understood about how to best address food insecurity and support students who are struggling with basic needs. The impact of food insecurity on students' academic and social success, in addition to their overall well-being, should be investigated and prioritised at each higher education institution. This is especially true for marginalised students, such as minority or first-generation students, who are at heightened risk for food insecurity. In order to create a culture of health equity, in which most at-risk students are provided resources and opportunities to achieve optimal well-being, higher education institutions must prioritise mitigating food insecurity on the college campus. Higher education institutions could benefit from adopting comprehensive and individualised approaches to promoting food security for marginalised students in order to facilitate equal opportunity for optimal scholastic achievement among students of all socio-demographic backgrounds.

Macronutrient intake during infancy and neurodevelopment in preschool children from the EDEN mother-child cohort

BACKGROUND

Although the deleterious effect of micronutrient deficiency at sensitive periods on neurodevelopment is well established, the potential influence of macronutrient intake on early life neurodevelopment of healthy term infants has been seldomly studied. We aimed to explore whether macronutrient intake at 12 months was related to neurodevelopmental scores in preschool children.

METHODS

Analyses were based on data from the EDEN mother-child cohort. Macronutrient intake was assessed by 3-day food records at 12 months of age. Neurodevelopment was assessed at 3 years using the French version of the Ages and Stages Questionnaire (ASQ) (n = 914), and at 5-6 years, using the French version of the Wechsler Preschool and Primary Scale of Intelligence-Third Edition (n = 785). An association between macronutrient intake and neurodevelopmental scores were analysed by multivariable linear regression for 3-year Full Score ASQ or 5-6-year intelligence quotient scores and multivariable logistic regression for 3-year ASQ subdomains.

RESULTS

Macronutrient intake in infancy was not associated with neurodevelopmental scores in preschool children. No association was found between PUFA intake and overall neurodevelopmental scores, after accounting for multiple testing.

CONCLUSION

In the present study, macronutrient intake at one year did not appear to influence the child's cognitive ability at 3 and 5-6 years. Further studies are needed to clarify the relationship between early fatty acid intake and neurodevelopment.

Impact of coronavirus disease 2019 on food security in early childhood

PURPOSE OF REVIEW

To summarize the impact of the COVID-19 pandemic on food insecurity during early childhood, with a focus on challenges and strategies to improve access to and consumption of nutritious food in early childcare and education settings.

RECENT FINDINGS

The COVID-19 pandemic exacerbated existing gaps and inequities in the early childcare and education system, resulting in closures and decreased access to healthy foods that disproportionately impacted black, indigenous, and people of color, as well as rural and low-income communities.

SUMMARY

Closures and changes in operational capacity not only stressed the early childcare and education system and its workforce but also contributed to financial strain and food insecurity among families with young children. Increased public investment and cross-sector partnerships can support and strengthen both early childcare and education and food systems, increasing equitable access to quality care and reducing food insecurity in early childhood.

Community Food Insecurity and Child Maltreatment Reports: County-Level Analysis of U.S. National Data From 2009 to 2018

Current literature suggests that food insecurity increases child maltreatment risk. Yet, existing evidence is limited to individual-level associations among low-income, high-risk populations based on local, mostly urban data. This study aims to generalize prior findings to community-level associations in general populations, using national data including all urban-rural areas. We examined, for the first time, if food insecurity rates increase child maltreatment report (CMR) rates at the county level after controlling for potential confounders. We examined both within-community longitudinal changes (i.e., within-effects) and inter-community differences (i.e., between-effects) of food insecurity rates and their associations with CMR rates. We also examined differences by age, sex, race/ethnicity, maltreatment type, and urbanicity. We constructed longitudinal county-level data by linking multiple national databases, including all substantiated and unsubstantiated CMR records, the Map the Meal Gap's community food insecurity estimates, and Census data. The data covered over 96% of U.S. counties from 2009 to 2018. For analysis, we used within-between random effects models. Regarding between-effects, we found that in inter-community comparisons, higher food insecurity rates were significantly associated with increased CMR rates. This association was consistent by age, sex, maltreatment type, and urbanicity. For within-effects, we found that the association between longitudinal changes of food insecurity rates and CMR rates significantly differed by urbanicity. Specifically, longitudinal increases of food insecurity rates significantly increased CMR rates among large urban counties, but not among small urban and rural counties. Study findings highlight the importance of conducting further research to better understand the mechanisms through which food insecurity impact child maltreatment at both individual and community levels. Our community-level findings from general populations especially have significant implications for community-based programs and large-scale policies to achieve population-level impact on child well-being.

Growth and growth trajectory among infants in early life: contributions of food insecurity and water insecurity in rural Zimbabwe

Introduction

Stunting or linear growth faltering, measured by length-for-age Z-score (LAZ), remains a significant public health challenge, particularly in rural low-income and middle-income countries. It is a marker of inadequate environments in which infants are born and raised. However, the contributions of household resource insecurities, such as food and water, to growth and growth trajectory are understudied.

Methods

We used the cluster-randomised Sanitation Hygiene and Infant Nutrition Efficacy trial to determine the association of household-level food insecurity (FI) and water insecurity (WI) on LAZ and LAZ trajectory among infants during early life. Dimensions of FI (poor access, household shocks, low availability and quality) and WI (poor access, poor quality, low reliability) were assessed with the multidimensional household food insecurity and the multidimensional household water insecurity measures. Infant length was converted to LAZ based on the 2006 WHO Child Growth Standards. We report the FI and WI fixed effects from multivariable growth curve models with repeated measures of LAZ at 1, 3, 6, 12 and 18 months (M1-M18).

Results

A total of 714 and 710 infants were included in our analyses of LAZ from M1 to M18 and M6 to M18, respectively. Mean LAZ values at each time indicated worsening linear growth. From M1 to M18, low food availability and quality was associated with lower LAZ (β=-0.09; 95% -0.19 to -0.13). From M6 to M18, poor food access was associated with lower LAZ (β=-0.11; 95% -0.20 to -0.03). None of the WI dimensions were associated with LAZ, nor with LAZ trajectory over time.

Conclusion

FI, but not WI, was associated with poor linear growth among rural Zimbabwean infants. Specifically, low food availability and quality and poor food access was associated with lower LAZ. There is no evidence of an effect of FI or WI on LAZ trajectory.

Intersection of food insecurity and moral experiences of those involved in paediatric healthcare: A scoping review of child, caregiver and healthcare provider perspectives

Food insecurity is a significant social and health issue for children in high-income countries and contributes to sub-optimal child outcomes. This scoping review examines how food insecurity intersects with the moral experiences of those involved in providing and receiving paediatric health care. Multiple databases were searched using a priori inclusion criteria, papers were screened by multiple reviewers. Searches yielded nine papers. Descriptive data was summarised and qualitative results extracted from included papers were analysed using inductive and deductive thematic analysis. Four main themes emerged: Food insecurity threatens caregiver and healthcare provider identity; is food insecurity the business of health? is screening for food insecurity surveillance or facilitating assistance? and the lived experience of navigating the tension of managing food insecurity and a child's health condition. The moral experiences lens has magnified the countless everyday encounters in which values and beliefs about what is 'right' or 'just' can be realised or thwarted in the context of the intersection between healthcare and food insecurity. Review findings have implications relating to the inclusion of children's voices in healthcare settings, healthcare practice and policy design, and the development and use of FI screening tools.

‘Mens sana in corpore Sano’: Home food consumption implications over child cognitive performance in vulnerable contexts

Diet directly affects children’s physical and mental development. Nonetheless, how food insecurity and household food consumption impact the cognitive performance of children at risk of social exclusion remains poorly understood. In this regard, children in Guatemala face various hazards, mainly related to the socioeconomic difficulties that thousands of families have in the country. The main objective of this study was to analyze the differences in cognitive performance considering food insecurity and household food consumption in a sample of rural and urban Guatemalan children and adolescents at risk of social exclusion. Child cognitive performance was assessed in 134 children and adolescents (age M = 11.37; SD = 3.54) from rural and urban settings. Language, attention, and executive functions were assessed using neuropsychological tasks. Differences in cognitive performance in each level of food insecurity and household diet consumption were compared using the Mann–Whitney U test. A stepwise multivariate regression analysis was conducted to determine which factors may influence cognitive scores. The results showed that rural and urban groups did not differ in terms of food insecurity. However, considering just rural areas, differences were found between groups with food security and insecurity in attention and executive function tasks. Moreover, differences were found in food consumption for certain groups of food (e.g., meat, U = 1,146, p < 0.001, g = 0.72). Regarding regressions, protein food consumption (e.g., meat and fish), which is related to having a more balanced diet, was a relevant factor in executive performance. Contrary to what we expected, performance in attentional tasks was not related to the consumption of any food group. These findings could help politicians and decision-makers to select actions focused on improving diet balance and food security in families at risk of social exclusion. It is necessary to carry out more specific studies on the factors related to diet that affect the cognitive development of minors at risk of social exclusion. In addition, it is necessary to study the implementation of alternative interventions that include low-cost nutrients, thus ensuring that minors have access to a more balanced diet.

The unique relevance of executive functions and self-regulation behaviors for understanding early childhood experiences and preschoolers' outcomes in rural Pakistan

Performance-based measures of children's executive functions (EFs) do not capture children's application of these skills during everyday emotionally-laden and socially-mediated interactions. The current study demonstrates the value of using assessor report of self-regulation behaviors (inhibitory control and positive affect/engagement) in addition to EF tasks when studying early childhood experiences and development in a rural lower-middle-income country setting. In a sample of 1302 disadvantaged 4-year-olds living in rural Pakistan, we found that directly assessed EFs were significantly related to assessor observations of children's inhibitory control and positive affect/engagement during a structured assessment protocol. However, EFs and two types of self-regulation behaviors demonstrated unique associations with children's (1) contextual experiences, as indexed by family socio-economic resources, participation in parenting interventions, and children's physical growth; and (2) age-salient developmental outcomes, as indexed by direct assessment of pre-academic skills and maternal report of prosocial behaviors and behavior problems. First, family wealth uniquely predicted only observed positive affect/engagement, whereas maternal education uniquely predicted only EFs. Second, children's antecedent linear growth was a significant predictor of both EFs and positive affect/engagement, but exposure to an enhanced nutrition intervention during the first 2 years of life and preschoolers' hair cortisol concentration were associated only with observed self-regulation behaviors. Finally, both EFs and observed positive affect/engagement uniquely predicted children's pre-academic skills. In contrast, only assessors' ratings of positive affect/engagement uniquely predicted maternal report of prosocial behaviors and only assessors' ratings of inhibitory control uniquely predicted maternal report of behavioral problems.

Food Insecurity among Low-Income Households with Children Participating in a School-Based Fruit and Vegetable Co-Op

The purpose of this study was to evaluate the impact of a nutrition intervention on food insecurity among low-income households with children. Data were collected from 371 parent−child dyads in a quasi-experimental evaluation study of a 1-year intervention (n = 6 intervention schools receiving Brighter Bites, n = 6 wait-list control schools), and longitudinal follow-up of the intervention group 2 years post-intervention in Houston, Texas. Data were collected at three timepoints: at baseline and 1 year for all participants, and at 2 year follow-up for the intervention group (the wait-list control group received the intervention during that time). At baseline, most parents reported food insecurity (60.6%; 70% intervention group, 53.6% control). Food insecurity decreased significantly from 81.3% to 61.7% [(−0.32, −0.07) p = 0.002] among intervention participants immediately post-intervention. After adjusting for ethnicity, 2 years post-intervention the predicted percentage of participants reporting food insecurity decreased significantly by roughly 35.4% from 76.4% at baseline to 41.0% [(−0.49, −0.22), p < 0.001]. Between-group changes were not significant. The re-sults of this study demonstrated a significant positive impact of Brighter Bites on food security in the short and long-term among low-income households with children, albeit results should be in-terpreted with caution.

Examining Associations Between Food Insecurity, Inhibitory Control, and Body Mass Index in Preschoolers

OBJECTIVE

This study examines relations between food insecurity, inhibitory control, and body mass index (BMI) in early childhood.

METHOD

The sample comes from an evaluation of a state-funded prekindergarten program and includes 126 children (mean age = 4.73 yrs, female = 42%) from families with low incomes. Parents reported on their child's food insecurity. Child inhibitory control was assessed using a performance-based task, and children's height and weight were objectively collected at the same time as the inhibitory control assessment. A regression model was used to test whether inhibitory control moderated the association between food insecurity and BMI. The model included a large battery of covariates and adjusted for clustering at the classroom level. Ad hoc analyses were conducted to examine the robustness of findings to different conceptualizations of food insecurity based on the US Department of Agriculture's categories for severity.

RESULTS

A significant interaction revealed that inhibitory control moderated the association between food insecurity and children's BMI percentile. Investigation of the simple slopes suggested that greater food insecurity was related to a higher BMI percentile among children who demonstrated stronger inhibitory control. In addition, results from ad hoc analyses examining categories of food insecurity indicated that experiencing very low food security was also related to a higher BMI among children with average and strong inhibitory control.

CONCLUSION

This study makes a unique contribution to the existing literature by examining relations among food insecurity, inhibitory control, and BMI during a critical period in children's physical and brain development. Findings have implications for public health efforts to address childhood obesity among populations with low incomes.

The mental health of children and young people living in big cities in a revolving postpandemic world

PURPOSE OF REVIEW

The world's population is increasingly urban, with most children and young people growing up and living in cities. Evidence suggests that urbanicity is linked to an increased risk for the development of mental health disorders. Rather than an accumulation of risk factors, urbanization is a complex process that profoundly structures living conditions. In this sense, it is timely to discuss what are the social and structural determinants of mental health of children and young people in such settings.

RECENT FINDINGS

Three domains of determinants of mental health were selected for discussion: economics and living conditions, crime and violence, and urban layouts. For each, we debated realities faced by urban children and young people, providing an overview of recent evidence on implications for mental disorders and well being. We also discuss the potential impacts of the covid-19 pandemic on each domain, as well as recommendations for future action.

SUMMARY

Structural factors are of major relevance for the mental health of children and young people living in cities. The agenda of mental health promotion and prevention must include whole-of-society interventions aimed at improving living conditions, including economic and social capital, violence prevention and urbanistic planning.

Mendelian randomization study on the causal effects of COVID-19 on childhood intelligence

Although individuals with coronavirus disease 2019 (COVID‐19) are known to be at increased risk for other conditions resulting from pathogenic changes (including metaplastic or anaplastic) in the lungs and other organs and organ systems, it is still unknown whether COVID‐19 affects childhood intelligence. The present two‐sample Mendelian randomization study aims to identify the genetic causal link between COVID‐19 and childhood intelligence. Four COVID‐19 genetic instrumental variants (IVs) were chosen from the largest genome‐wide association studies (GWAS) for COVID‐19 (hospitalized vs. population) (6406 cases and 902 088 controls of European ancestry). The largest childhood intelligence GWAS (n = 12 441 individuals of European ancestry) was used to evaluate the effect of the identified COVID‐19‐associated genetic IVs on childhood intelligence. We found that as the genetic susceptibility to COVID‐19 increased, childhood intelligence followed a decreasing trend, according to mr_egger (β = −0.156; p = 0.601; odds ratio [OR] = 0.856; 95% confidence interval [CI]: 0.522–1.405), simple mode (β = −0.126; p = 0.240; OR = 0.882; 95% CI: 0.745–1.044), and weighted mode (β = −0.121; p = 0.226; OR = 0.886; 95% CI: 0.758–1.036) analyses. This trend was further demonstrated by the weighted median (β = −0.134; p = 0.031; OR = 0.875; 95% CI: 0.774–0.988) and the inverse variance weighted (β = −0.152; p = 0.004; OR = 0.859; 95% CI: 0.776–0.952). Our analysis suggests a causal link between genetically increased COVID‐19 and decreased childhood intelligence. Thus, COVID‐19 may be a risk factor for declines in childhood intelligence.

Households' Food Insecurity and Their Association With Dietary Intakes, Nutrition-Related Knowledge, Attitudes and Practices Among Under-five Children in Gaza Strip, Palestine

The present study aimed to determine the households' food insecurity and their association with dietary intakes, nutrition-related knowledge, attitudes and practices (KAP) among under-five children in the Gaza Strip, Palestine. This cross-sectional study was conducted in 2021 among a representative sample of under-five children. A total of 350 children and their proxy were selected from all Gaza strip governorates, using a cluster random sampling method. The Radimer/Cornell food-security scale was used. A 24-h dietary recall was employed for dietary intakes assessment. Nutrition-related KAP for feeding under-five children, anthropometric measurements, and demographic-socioeconomic characteristics were obtained with an interview-based questionnaire. Statistical analysis was performed using SPSS version 25. The children from food-insecure households had a high prevalence of moderate underweight (30.4%), stunting (32.8%), wasting (9.6%), and acute undernutrition (30.4%). Between food-insecure and food-secure groups there were significant differences in weight, height/length, mid-upper arm circumference, weight-for-age and mid-upper arm circumference z-scores, underweight, acute undernutrition, intakes of protein, fat, vitamin D, zinc, continued breastfeeding, having nutrition-related adequate knowledge, having nutrition-related positive attitudes, and achieved minimum dietary diversity score (P < 0.05 for all). Additionally, about (56.0%) food-insecure households have inadequate nutrition-related knowledge, (77.6%) have nutrition-related negative attitudes, and (95.2%) did not achieve a minimum dietary diversity score. In conclusion, the children from food-insecure households had a high prevalence of moderate underweight, stunting, wasting, and acute undernutrition. Moreover, low economic status, poor dietary intakes, low levels of nutrition-related KAP, and lack of dietary diversity could contribute to the high levels of food insecurity among under-five children.

Nutritional Risk in Early Childhood and School Readiness

BACKGROUND

Nutrition in early childhood is important for healthy growth and development. Achieving school readiness is considered one of the most important developmental milestones for young children.

OBJECTIVES

The purpose of this study is to determine if nutritional risk in early childhood is associated with school readiness in kindergarten.

METHODS

A prospective cohort study was conducted through The Applied Research Group for Kids (TARGet Kids!) primary care research network in Toronto, Canada, 2015-2020. Nutritional risk was measured (18 mo to 5 y) using validated parent-completed questionnaires called Nutrition Screening for Toddlers and Preschoolers (NutriSTEP). High nutritional risk was categorized as scores ≥21. School readiness was measured using the validated teacher-completed Early Developmental Instrument (EDI), which measures 5 developmental domains in kindergarten (2 y of schooling, ages 4-6 y, before they enter grade 1). Vulnerability indicates scores lower than a population-based cutoff at the 10th percentile on at least 1 domain. Multiple logistic and linear regression models were conducted adjusting for relevant confounders.

RESULTS

The study included 896 children: 53% were male, 9% had high nutritional risk, and 17% were vulnerable on the EDI. A 1-SD increase in NutriSTEP total score was associated with 1.54 times increased odds of being vulnerable on the EDI among children in year 2 of kindergarten (P = 0.001). High nutritional risk cutoff was associated with 4.28 times increased odds of being vulnerable on the EDI among children in year 2 of kindergarten (P < 0.001). NutriSTEP total score and high nutritional risk were associated with lower scores on all 5 EDI domains, with the strongest association observed for the domains of language and cognitive development and communication skills and general knowledge.

CONCLUSIONS

Higher nutritional risk in early childhood is associated with lower school readiness in year 2 of kindergarten. Nutritional interventions early in life may offer opportunities to enhance school readiness. This trial was registered www.clinicaltrials.gov as NCT01869530.

Food insecurity and the nutritional health and well-being of women and children in high-income countries: protocol for a qualitative systematic review

INTRODUCTION

Since the global financial crises of 2008, there has been a rise in the number of people experiencing food insecurity. The COVID-19 pandemic has exacerbated this. Many more are unable to afford or access food of sufficient quality and quantity to enable good health and well-being. Particularly vulnerable are mothers with young children, pregnant women and lone parents (the majority of whom are women). This review aims to understand experiences of food insecurity and how it affects women and children's nutritional health and well-being, focusing on experiences explicitly related to nutrition. Findings will help guide health policy and practice to support food-insecure women and children from high-income countries.

METHODS AND ANALYSIS

A systematic review and meta-ethnography exploring (1) food-insecure women's own accounts of their nutritional health and (2) food-insecure household's accounts of their children's nutritional health. Six major databases (MEDLINE, Scopus, Web of Science, EMBASE, CINAHL and ASSIA), grey literature databases and relevant stakeholder websites will be searched from 1 January 2008 to 30 March 2021. Reference list and citation searches will supplement electronic database searches. Outcomes of interest are accounts of nutrition and nutritional health, including diet, food practices, infant feeding practices and physical and mental health. The review will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol guidelines, but as this is a meta-ethnography it will adhere to eMERGe Reporting Guidance for synthesis and writing findings of the final report. Critical Appraisal Skills Programme qualitative checklist will assess the quality of studies. A meta-ethnographic analysis will be conducted for all included studies.

ETHICS AND DISSEMINATION

As a qualitative systematic review, without primary data collection, ethical approval will not be required. Findings will be submitted for peer-reviewed publication.

Food Insecurity and Child Development: A State-of-the-Art Review

Converging research indicates that household food insecurity impedes children from reaching their full physical, cognitive, and psychosocial potential. This state-of-the-art review examines the last decade of research to: (1) describe the impact of the severity and persistence of food insecurity on child development; (2) use a socio-ecological framework to examine significant proximal and distal factors which may interplay; and (3) outline directions for future research. We conducted a systematic review of six databases of published papers from 2011 to June 2021. The search was limited to high-income countries and children aged from birth to 12 years. From 17,457 papers, 17 studies were included in the final review. Transitioning between food security and food insecurity had a significant and lasting effect on academic/cognitive function and behavior (i.e., externalizing), however less clear relationships were seen for psychosocial outcomes and other behaviors examined (i.e., internalizing). There was significant variation in the measurement and thresholds used to define both food insecurity and child development outcomes. Subsequently, comparisons across studies are difficult. Several future recommendations, including incorporation of socio-ecological factors, is provided. In conclusion, this review supports the link between food insecurity and sub-optimal child development; however, there is an imperative to improve and extend current understanding to ameliorate the causes of food insecurity.

Household food insecurity and early childhood development in Brazil: an analysis of children under 2 years of age

OBJECTIVE

To determine if household food insecurity (HFI) is associated with the risk of developmental delays.

DESIGN

Cross-sectional study of a representative sample of children under 2 years old. Risk of developmental delays was assessed with the Denver Developmental Screening Test II. HFI was measured with the Brazilian Food Insecurity Measurement Scale. Multivariable logistic regression was used to test the association between HFI (food secure/insecure) and risk of developmental delays, adjusting for household, maternal and child variables.

SETTING

Community Health Centers in the Federal District, Brazil.

PARTICIPANTS

1004 children under 2 years old.

RESULTS

Among participants, 15 % were at risk of developmental delays and about 40 % of children lived in food-insecure households. HFI was associated with the risk of developmental delays (adjusted OR 2·61; 95 % CI 1·42, 4·80) compared with food-secure households after adjusting for key confounders.

CONCLUSIONS

HFI was strongly associated with the risk of developmental delays in children under 2 years. Investments that prevent or mitigate HFI are likely to be key for improved human and national development.

Maternal Mental Health Mediates the Relationship Between Household Food Insecurity and Early Child Development in Brazil

BACKGROUND

Optimal early child development (ECD) is fundamental for every child to achieve their developmental potential and thrive. Household food insecurity (HFI) is a risk factor for suboptimal development, but there is still a need to better understand the pathways that explain this relationship.

OBJECTIVE

To evaluate whether maternal mental health and infant's diet mediate the association between HFI and ECD using structural equation modeling.

METHODS

Cross-sectional study with 474 mother-infant dyads. Mothers answered a questionnaire that evaluated variables through validated instruments. Structural equation modeling analyses were conducted to obtain standardized effects (β) and bias-corrected 95% CI, enabling comparisons between the magnitude of the effects. The following observed variables were included: HFI, ECD, consumption of a healthy and diverse diet, the presence of a partner in the household, wanted pregnancy, and current breastfeeding. Latent variables were included to evaluate mental health, poverty, and neonatal health.

RESULTS

Poor maternal mental health mediated the relationship between HFI and ECD (β = -.05), but a healthy and diverse diet was not a mediator in this relationship. Poverty was related to lower development scores directly (β = .21) and indirectly (β = .02). Not having a partner (β = .05) and having an unwanted pregnancy (β = .02) predicted indirectly lower development scores.

CONCLUSIONS

Poor maternal mental health mediates the relationship between HFI and ECD, and ECD is influenced by poverty, single motherhood, and unwanted pregnancy through different pathways. Therefore, public policies and interventions that aim to promote an optimal ECD should also approach these aspects.

Household food insecurity and school readiness among preschool-aged children in the USA

OBJECTIVE

The present study examines the association between mild and moderate-to-severe household food insecurity and school readiness among a nationally representative sample of preschool-aged children.

DESIGN

Cross-sectional data pertaining to household food availability as well as four domains of school readiness - early learning skills, self-regulation, social-emotional development and physical health & motor development - were employed.

SETTING

The USA.

PARTICIPANTS

15 402 children aged 3-5 years from the 2016-2018 National Survey of Children's Health.

RESULTS

Both mild and moderate-to-severe food insecurity are associated with an increase in needing support or being at-risk in each of the four school readiness domains, particularly Self-Regulation (IRR = 4·31; CI 2·68, 6·95) and Social-Emotional Development (IRR = 3·43; CI 2·16, 5·45). Furthermore, while nearly half of the children in food-secure households are on-track across all four school readiness domains (47·49 %), only one in four children experiencing moderate-to-severe household food insecurity is on-track across all domains (25·26 %).

CONCLUSIONS

Household food insecurity is associated with reductions in school readiness among preschool-aged children.

Food insecurity measurement and prevalence estimates during the COVID-19 pandemic in a repeated cross-sectional survey in Mexico

OBJECTIVE

To validate the telephone modality of the Latin American and Caribbean Food Security Scale (ELCSA) included in three waves of a phone survey to estimate the monthly household food insecurity prevalence during the COVID-19 pandemic in Mexico.

DESIGN

We examined the reliability and internal validity of the ELCSA scale in three repeated waves of cross-sectional surveys with Rasch models. We estimated the monthly prevalence of food insecurity in the general population and in households with and without children and compared them with a national 2018 survey. We tested concurrent validity by testing associations of food insecurity with socio-economic status and anxiety.

SETTING

ENCOVID-19 is a monthly telephone cross-sectional survey collecting information on the well-being of Mexican households during the pandemic lockdown. Surveys used probabilistic samples, and we used data from April (n 833), May (n 850) and June 2020 (n 1674).

PARTICIPANTS

Mexicans 18 years or older who had a mobile telephone.

RESULTS

ELCSA had an adequate model fit and food insecurity was associated, within each wave, with more poverty and anxiety. The COVID-19 lockdown was associated with an important reduction in food security, decreasing stepwise from 38·9 % in 2018 to 24·9 % in June 2020 in households with children.

CONCLUSIONS

Telephone surveys were a feasible strategy to monitor reductions in food security during the COVID-19 lockdown.

Associations between Governmental Policies to Improve the Nutritional Quality of Supermarket Purchases and Individual, Retailer, and Community Health Outcomes: An Integrative Review

Supermarkets are natural and important settings for implementing environmental interventions to improve healthy eating, and governmental policies could help improve the nutritional quality of purchases in this setting. This review aimed to: (1) identify governmental policies in the United States (U.S.), including regulatory and legislative actions of federal, tribal, state, and local governments, designed to promote healthy choices in supermarkets; and (2) synthesize evidence of these policies' effects on retailers, consumers, and community health. We searched five policy databases and developed a list of seven policy actions that meet our inclusion criteria: calorie labeling of prepared foods in supermarkets; increasing U.S. Department of Agriculture (USDA) Supplemental Nutrition Assistance Program (SNAP) benefits; financial incentives for the purchase of fruit and vegetables; sweetened beverage taxes; revisions to the USDA Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food package; financial assistance for supermarkets to open in underserved areas; and allowing online purchases with SNAP. We searched PubMed, Econlit, PsycINFO, Web of Science, and Business Source Ultimate to identify peer-reviewed, academic, English-language literature published at any time until January 2020; 147 studies were included in the review. Sweetened beverage taxes, revisions to the WIC food package, and financial incentives for fruits and vegetables were associated with improvements in dietary behaviors (food purchases and/or consumption). Providing financial incentives to supermarkets to open in underserved areas and increases in SNAP benefits were not associated with changes in food purchasing or diet quality but may improve food security. More research is needed to understand the effects of calorie labeling in supermarkets and online SNAP purchasing.

Maternal mental health modifies the association of food insecurity and early child development

We examined the association between household food insecurity and early child development and whether or not maternal depression and anxiety modifies this association. The cross-sectional study included 468 mother-infant pairs recruited at primary health centers of the Federal District, Brazil. Mothers answered a questionnaire that evaluated early child development (outcome), household food insecurity (independent variable), maternal depression and trait anxiety (effect modifiers). Variables were collected with validated questionnaires for the Brazilian population. Pearson's χ2 test and logistic regression analyses were conducted. Infants who lived in a moderate or severe food insecure household had 2.52 times (95% confidence interval [CI] [1.13, 5.65]) the odds of having early child development delays compared with infants in secure households. Maternal depression and anxiety modified the strength of association between household food insecurity and early child development, which is an innovative finding. Among infants with depressed mothers, those experiencing mild (adjusted odds ratio [aOR] 3.33, 95% CI [1.17, 9.46]) and moderate/severe household food insecurity (aOR 10.13, 95% CI [2.18, 47.10]) had higher odds of having early child development delays, compared with infants in food secure households. Among infants with both anxious and depressed mothers, these associations were even stronger for mild (aOR 4.69, 95% CI [1.41, 15.59]) and moderate/severe household food insecurity (aOR 16.07, 95% CI [2.70, 95.66]). In conclusion, household food insecurity is a risk factor for early child development delays, and this association is modified by maternal depression and anxiety. Future studies should evaluate the impact of intervention packages that address maternal depression and anxiety and household food insecurity on preventing early child development delays.

COVID-19 and maternal and child food and nutrition insecurity: a complex syndemic

Globally, the COVID‐19 pandemic has already led to major increases in unemployment and is expected to lead to unprecedented increases in poverty and food and nutrition insecurity, as well as poor health outcomes. Families where young children, youth, pregnant and lactating women live need to be protected against the ongoing protracted pandemic and the aftershocks that are very likely to follow for years to come. The future wellbeing of the vast majority of the world now depends on reconfiguring the current ineffective food, nutrition, health, and social protection systems to ensure food and nutrition security for all. Because food, nutrition, health, and socio‐economic outcomes are intimately inter‐linked, it is essential that we find out how to effectively address the need to reconfigure and to provide better intersecoral coordination among global and local food, health care, and social protection systems taking equity and sutainability principles into account. Implementation science research informed by complex adaptive sytems frameworks will be needed to fill in the major knowledge gaps. Not doing so will not only put the development of individuals at further risk, but also negatively impact on the development potential of entire nations and ultimately our planet.

Household food insecurity and early childhood development: Systematic review and meta-analysis

Household food insecurity (HFI) is a powerful stressor negatively associated with early childhood development (ECD). However, no comprehensive review has examined the association of HFI and ECD. Therefore, this systematic review and meta-analysis investigated the association between HFI and ECD domains and subdomains in children under 5 years old. Peer-reviewed and grey literature were systematically searched in electronic databases with no year or language restrictions. Studies were eligible if they assessed the association between HFI and one or more ECD domains. Data were extracted using a standard predefined protocol. Meta-analysis was performed, and the heterogeneity across studies was explored. Nineteen studies were included in the systematic review and 14 in the meta-analysis. Of the studies, 15 were from high income countries (HICs) and four from low-middle income countries (LMICs). For developmental risk and the cognitive/math and cognitive/school readiness and reading subdomains, the only studies available were conducted in HICs. The meta-analysis showed that HFI was associated with developmental risk (OR 1.28; 95% CI [1.14, 1.45]), cognitive/vocabulary (OR 0.94; 95% CI [0.90, 0.98]), and cognitive/math (OR 0.84; 95% CI [0.73, 0.96]). HFI was marginally associated with cognitive/school readiness and reading (OR 0.91; 95% CI [0.82, 1.00]) and motor development (OR; 0.91, 95% CI [0.80, 1.04]). HFI was associated with poor ECD in children under 5 years old. Specifically, HFI was associated with developmental risk and poor math skills in studies conducted in HICs and with poor vocabulary skills in studies conducted in both HICs and LMICs. Prospective studies examining HFI and ECD are needed in LMICs.
