Project description:For a decade, Feeding America's Map the Meal Gap (MMG) has provided sub-state-level estimates of food insecurity for both the full population and for children. Along with being extensively used by food banks, it is widely used by state and local governments to help plan responses to food insecurity in their communities. In this paper, we describe the methods underpinning MMG, detail the approach Feeding America has used to make projections about the geography of food insecurity in 2020, and how food insecurity rates may have changed due to COVID-19 since 2018. We project an increase of 17 million Americans who are food insecure in 2020 but this aggregate increase masks substantial geographic variation found in MMG.

Project description: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.

Project description:Soaring landbirds typically exploit atmospheric uplift as they fly overland, displaying a highly effective energy-saving locomotion. However, large water bodies lack thermal updrafts, potentially becoming ecological barriers that hamper migration. Here we assessed the effects of a sea surface on the migratory performance of GPS-tagged white storks (Ciconia ciconia) before, during and after they crossed the straits of Gibraltar. Oversea movements involved only flapping and gliding and were faster, traversed in straighter, descending trajectories and resulted in higher movement-related energy expenditure levels than overland, supporting the water barrier hypothesis. Overland movements at both sides of the sea straits resulted in tortuous routes and ascending trajectories with pre-crossing flights showing higher elevations and more tortuous routes than post-crossing, thus supporting the barrier negotiation hypothesis. Individual positions at both ends of the sea narrow were predicted by zonal winds and storks´ location at entry in the European hinterland, and birds did not show compensational movements overland in anticipation to subsequent wind displacements oversea. The length of the water narrow at departure shore, the elevation therein and the winds on route affected major components of sea crossing performance (such as distances and times overwater, minimum elevations, climb angles, speeds and energy expenditure), supporting the departure position and oversea winds hypotheses. In summary, our study provides a prime example at high temporal resolution of how birds adjust their behavior and physiology as they interact with the changing conditions of the travelling medium, reallocating resources and modifying their movement to overcome an ecological barrier.

Project description:ObjectiveTo assess, from a systems perspective, how climate vulnerability and socio-economic and political differences at the municipal and state levels explain food insecurity in Mexico.DesignUsing a cross-sectional design with official secondary data, we estimated three-level multinomial hierarchical linear models.SettingThe study setting is Mexico's states and municipalities in 2014.ParticipantsHeads of households in a representative sample of the general population.ResultsAt the municipal level, vulnerability to climate disasters and a poverty index were significant predictors of food insecurity after adjusting for household-level variables. At the state level, gross domestic product and the number of nutrition programmes helped explain different levels of food insecurity but change in political party did not. Predictors varied in strength and significance according to the level of food insecurity.ConclusionsFindings evidence that, beyond food assistance programmes and household characteristics, multiple variables operating at different levels - like climate vulnerability and poverty - contribute to explain the degree of food insecurity. Food security governance is a well-suited multisectoral approach to address the complex challenge of hunger and access to a nutritious diet.

Project description:Among rural families, rates of both child obesity and household food insecurity (FI) are higher compared to non-rural families. These disparities result from a complex interplay of social and environmental conditions that influence behavior. The Transtheoretical Model suggests individual readiness to change underlies success in modifying obesity-preventing behaviors; however, whether an association between readiness to change obesity-related behaviors and FI status among rural families exists is unknown. We examined the association between readiness to change family-level nutrition and physical activity (PA) behaviors that predict child obesity and family FI status within a sample of rural families to better understand these relationships. Families (n = 144) were recruited from six rural Oregon communities in 2013. Families completed a FI screener and the Family Stage of Change Survey (FSOC), a measure of readiness to change family-level nutrition and PA behaviors associated with obesity. Demographic differences by FI status were explored, and regression was applied to examine relationships between FI and FSOC scores, adjusting for relevant covariates. Among FI families (40.2%), more were non-white (77.8% vs. 22.2%; p = 0.036) and had lower adult education (30.4% vs. 11.8% with > high school degree; p = 0.015) compared to non-FI families. After adjusting for education, race, ethnicity, and eligibility for federal meal programs, readiness to provide opportunities for PA was lower among FI families (p = 0.002). These data highlight a need to further investigate how food insecurity and low readiness to provide PA opportunities, i.e. "physical activity insecurity" may be contributing to the higher obesity rates observed among rural children and families.

Project description:Household food insecurity (HFI) is a significant problem in the developing world. Relationships between HFI and nutrition, physical growth, and development have been elucidated; less is known about the non-nutritional impacts among individuals living in rural areas in low-income countries. The aim of this study was to determine if HFI is a risk factor for suboptimal mental health and overall health in rural Honduras. In a population of 24,696 adults with 176 isolated villages in western Honduras, we collected data on household food insecurity and physical and mental health outcome measures. Using logistic regression with and without adjusting for village and household level unobservables invariant across individual respondents, we show that females (OR: 1.11, p <0.01)), indigenous people (OR: 2:00, p < 0.01), and those planning to migrate (OR: 1.24, p <0.01) have higher odds of experiencing food insecurity. The risks of food insecurity and poor health were mitigated among respondents living where they were born and having multi-generations of relatives living in the same village-a measure of the opportunity and availability of social networks. Living in a food insecure compared to a food secure household was associated with 77 percent higher odds of being depressed, 35 percent higher odds of low overall mental health, and 20 percent higher odds for low overall health.

Project description:ObjectiveTo identify factors associated with the presence and severity of food insecurity among a sample of Honduran caregivers of young children.DesignCross-sectional study in which the dependent variable, household food insecurity, was measured using a fourteen-item questionnaire developed and validated in a population of similar cultural context. A predictive modelling strategy used backwards elimination in logistic regression and multinomial logit regression models to compute odds ratios and 95% confidence intervals for food insecurity.SettingRural Honduras in the department of Intibucá, between March and April 2009.SubjectsTwo-hundred and ninety-eight Honduran caregivers of children aged 6-18 months.ResultsNinety-three per cent of households were classified as having some degree of food insecurity (mild, moderate or severe). After controlling for caregiver age and marital status, compared with caregivers with more than primary-school education, those with less than primary-school education had 3·47 (95% CI 1·34, 8·99) times the odds of severe food insecurity and 2·29 (95% CI 1·00, 5·25) times the odds of moderate food insecurity. Our results also found that child anthropometric status was not associated with the presence or severity of food insecurity.ConclusionsThese results show that among the sociodemographic factors assessed, food insecurity in rural Honduras is associated with maternal education. Understanding key factors associated with food insecurity that are unique to Honduras can inform the design of interventions to effectively mitigate the negative impact of food insecurity on children.

Project description:PurposeEconomic instability is a significant and growing problem among emerging adults in the U.S. This study identifies adolescent factors across multiple levels of influence that predict homelessness and food insecurity 5 years later.MethodsThe analytic sample (n = 2,110) completed a survey in 2015-2016 (mean age 17) that assessed a range of demographic, behavioral health, family, peer, academic, and neighborhood factors, and a follow-up survey in 2019-2020 (mean age 23) that assessed past-year homelessness and food insecurity. Logistic regression analyses were conducted for the full sample, and by race/ethnicity.ResultsAt follow-up, 7.5% of participants reported homelessness, and 29.3% reported food insecurity. Multivariate analyses indicated that only adverse childhood experiences and weaker academic orientation predicted both outcomes. Future homelessness was additionally predicted by greater exposure to substance using peers during adolescence. Identifying as Hispanic, lower maternal education, and greater neighborhood disorganization were risk factors for future food insecurity, and living with both biological parents and better mental health were protective factors. Race/ethnicity stratified models showed variations in multilevel predictors of both outcomes, except for adverse childhood experiences, which were significant across all subgroups.ConclusionsAdverse childhood experiences and weaker academic orientation emerged as the most robust predictors of economic instability in emerging adulthood. However, a range of other modifiable multilevel predictors in adolescence were identified that were unique to homelessness or food insecurity and that varied by race/ethnicity. Results suggest the need for multilevel approaches early in life to reduce risk of economic instability during emerging adulthood.

Project description:Background and objectivesPregnancy, infancy, and toddlerhood are sensitive times in which families are particularly vulnerable to household food insecurity and when disparities in child obesity emerge. Understanding obesity-promoting infant-feeding beliefs, styles, and practices in the context of food insecurity could better inform both food insecurity and child obesity prevention interventions and policy guidelines.MethodsWe performed purposive sampling of low-income Hispanic mothers (n = 100) with infants in the first 2 years of life, all of whom were participants in a randomized controlled trial of an early child obesity prevention intervention called the Starting Early Program. Bilingual English-Spanish interviewers conducted semistructured qualitative interviews, which were audio recorded, transcribed, and translated. By using the constant comparative method, transcripts were coded through an iterative process of textual analysis until thematic saturation was reached.ResultsThree key themes emerged: (1) contributors to financial strain included difficulty meeting basic needs, job instability, and high vulnerability specific to pregnancy, infancy, and immigration status; (2) effects on infant feeding included decreased breastfeeding due to perceived poor maternal diet, high stress, and limiting of healthy foods; and (3) coping strategies included both home- and community-level strategies.ConclusionsStakeholders in programs and policies to prevent poverty-related disparities in child obesity should consider and address the broader context by which food insecurity is associated with contributing beliefs, styles, and practices. Potential strategies include addressing misconceptions about maternal diet and breast milk adequacy, stress management, building social support networks, and connecting to supplemental nutrition assistance programs.
