Book Description
Little research has been conducted on the association of food insecurity, particularly at the moderate level, and dietary consumption in low- and middle-income countries. This study expands on previous works by considering cross-country comparable measures of food insecurity that are calibrated against the global Food Insecurity Experience Scale (FIES). The FAO Statistics Division has been publishing estimates of the prevalence of food insecurity, based on the FIES, since 2017. The FIES is the first standardized measure, of people's direct experiences of food insecurity, appropriate for application on a global scale. The prevalence of moderate or severe food insecurity based on the FIES is one of the official SDG indicators (2.1.2). The objective of this study is to explore the relationship between the severity of food insecurity, as measured with the FIES (or an analogous experience-based food insecurity scale calibrated to the global reference scale), and dietary intake using microdata from four middle-income countries from different world regions: Kenya, Mexico, Samoa, and Sudan.

Book Description
The United States is viewed by the world as a country with plenty of food, yet not all households in America are food secure, meaning access at all times to enough food for an active, healthy life. A proportion of the population experiences food insecurity at some time in a given year because of food deprivation and lack of access to food due to economic resource constraints. Still, food insecurity in the United States is not of the same intensity as in some developing countries. Since 1995 the U.S. Department of Agriculture (USDA) has annually published statistics on the extent of food insecurity and food insecurity with hunger in U.S. households. These estimates are based on a survey measure developed by the U.S. Food Security Measurement Project, an ongoing collaboration among federal agencies, academic researchers, and private organizations. USDA requested the Committee on National Statistics of the National Academies to convene a panel of experts to undertake a two-year study in two phases to review at this 10-year mark the concepts and methodology for measuring food insecurity and hunger and the uses of the measure. In Phase 2 of the study the panel was to consider in more depth the issues raised in Phase 1 relating to the concepts and methods used to measure food security and make recommendations as appropriate. The Committee on National Statistics appointed a panel of 10 experts to examine the above issues. In order to provide timely guidance to USDA, the panel issued an interim Phase 1 report, Measuring Food Insecurity and Hunger: Phase 1 Report. That report presented the panel's preliminary assessments of the food security concepts and definitions; the appropriateness of identifying hunger as a severe range of food insecurity in such a survey-based measurement method; questions for measuring these concepts; and the appropriateness of a household survey for regularly monitoring food security in the U.S. population. It provided interim guidance for the continued production of the food security estimates. This final report primarily focuses on the Phase 2 charge. The major findings and conclusions based on the panel's review and deliberations are summarized.

Book Description
A review of 120 studies published since 2006 was undertaken to examine the relationship between food insecurity at the household or individual level and the following nutrition indicators: child stunting, child wasting, low birth weight, exclusive breastfeeding of infants < 6 months of age, anaemia in women of reproductive age, child overweight and adult obesity. While there is some evidence of a direct association between food insecurity and stunting for children in lower-middle and upper-middle income countries, evidence of links between food insecurity and either child wasting or overweight is almost absent, with the exception of an association with overweight among girls in middle- and high-income countries. The obesity–food insecurity link is most predominant among women in high-income countries, while it is almost absent in men. In addition, food insecurity increases the risk for low birth weight in infants and anaemia in women. Methodological concerns that pose challenges for valid comparison of results relate to study design, data analysis techniques, use of different indicators of household/individual food security and malnutrition, and the limited availability of high-quality micro-level data from large-scale surveys. Most studies report correlation rather than causal associations between food insecurity and nutrition indicators; longitudinal micro-level data from large-scale surveys can help establish causal association and capture the dynamic nature of food insecurity. Food insecurity emerges as a predictor of undernutrition as well as overweight and obesity, highlighting the need for multisectoral strategies and policies to combat food insecurity and multiple forms of malnutrition.

Book Description
Food insecure individuals do not always have access to adequate food for a healthy lifestyle and are at high risk of detrimental health outcomes. Researchers hypothesize that food insecurity leads to changes in dietary practices, including greater overall food purchase in times of adequate resources and purchase of low-cost, unhealthful foods when resources are constrained. Most measures of food insecurity do not measure changes in dietary practices and dietary quality. Research findings suggest education that provides alternative strategies to manage resources and improve dietary practices can improve food insecurity. We assessed the relationship between 1) food security and ability to afford foods and 2) the impact of Expanded Food and Nutrition Education Program (EFNEP) in a low-income, multi-cultural population in Massachusetts. We used a pre/post-education survey design, including the USDA six-item Food Security Module (FSM), food-affordability questions and EFNEP behavior checklist. EFNEP participants experienced high rates of food insecurity with over 40% of participants classified as food insecure (N=80). Pre-EFNEP, individuals in households with low food security were less likely to report being able to afford healthy foods (51.5%) and fruits and vegetables (57.6%) throughout the month compared to those in households with high (80.9%) and marginal (78.7%) food security (P=0.007, P=0.051). Individuals in households with marginal, low and very low food security were less likely to report being able to afford the same kinds of food throughout the month compared to individuals in high food secure households (56.4% vs. 84%) (P=0.022). Individuals in food insecure households reported running out of food before the end of the month more often than their food secure peers (P=0.013). Post-EFNEP, a greater proportion of participants fell into the high and marginal categories of food security (60.0% to 71.7%, P=0.065). Our results indicate that food insecure households have a harder time affording healthy foods throughout the month, leading to poor diet quality that possibly contributes to poor health outcomes. The food affordability questions may capture changes in dietary practices in food insecure populations throughout the month. EFNEP can provide skills and knowledge to at risk populations to improve abilities and combat food insecurity.

Book Description
This dissertation focuses on dietary intake patterns of children from low-income communities, and specifically the relationships of diet to food insecurity and school nutrition programs, respectively. The dissertation is divided into two parts. Part I discusses issues surrounding the measurement of food insecurity among children and provides support for the use of self-reported food insecurity measures, and for investigating effects that may differ by gender. Paper 1 explores the relationship between self-reported food insecurity and diet separately for boys and girls, using a dataset of 3,582 fourth and fifth grade students from San Diego area elementary schools. It concludes that among food-insecure children, gender may interact with food insecurity to influence eating behavior, with girls more prone than boys to alter their eating. Findings support a rationale to reduce child food insecurity and to address eating patterns that may place girls at greater risk for energy imbalances during critical periods of development. Part II focuses on the role of school nutrition programs in reducing food insecurity and improving dietary intake among participants. It introduces the Community Eligibility Provision (CEP), discusses relevant legislation and political trends, and provides a conceptual framework for hypothesized pathways through which CEP may influence student outcomes. Paper 2 examines associations between CEP and school meal participation among students who are eligible for free or reduced-price meals (FRPM), near the eligibility cutoff but possibly eligible, or above the cutoff and ineligible, using a difference-in-difference framework and a cross-sectional national sample of 2,305 students from grades K-8. It finds that CEP is associated with higher participation in school breakfast and lunch, particularly among those who were above the cutoff and would not have had access to free or reduced-price meals through a 3-tiered application and certification model. Paper 3 investigates associations among school meal participation, CEP, and dietary intake patterns using a larger sample of 4,124 students from grades K-8. It uses a regression framework to identify whether CEP is an effect modifier of relationships between school meal participation and dietary measures. It concludes that CEP is modestly associated with improved dietary intakes and may help reduce nutritional disparities for students in high-poverty schools. Finally, a special supplemental section explores the extent to which endogeneity in meal participation at CEP schools is a potential threat to these conclusions, using an instrumental variable approach to help control for omitted variables. There was no evidence to support the hypothesis that the dietary effects identified in Paper 3 resulted from shifting the source of student meals from home to school for the subset of students whose participation was induced by CEP. The dissertation concludes with a discussion of alternative explanations for the relationships found.

Affecting more than 800 million people, food insecurity is a global problem that runs deeper than hunger and undernutrition. In addition to the obvious impact on physical well-being, food insecurity can result in risky coping strategies, increased expenditures on medical costs or transportation, and mental health issues.

Book Description
"Research has found a paradoxical relationship between food insecurity and increased obesity, which disproportionately affects low-income women. The relationship between food insecurity and obesity is mediated by diet quality where food insecurity has a negative effect on overall diet quality, promoting excess energy intake and subsequent weight gain. Some research indicates that there may also be intra-monthly changes in diet quality and food availability among women in food insecurity. Thus, the goal of this research was to understand the extent by which the availability of a variety of foods, a critical component of food insecurity, occurs at the household level and how it affects dietary intake patterns and liking for palatable foods. The objectives were to: 1) examine associations between food insecurity and monthly changes in variety of food available at the household level, 2) examine associations between food insecurity and changes in diet quality at a monthly level, 3) determine associations between food insecurity and food reward sensitivity using self-reported and brain fMRI scan assessments. A cross-sectional exploratory research study of 13 low-income adult women was conducted to address these objectives. Participants completed two telephone interviews and two brain Magnetic Resonance Imaging (MRI) scans in the beginning and end of month periods based on their typical monthly income cycles. Food insecurity was prevalent among participants (69%). Participants reported a low variety of fresh fruits and vegetables at both interviews, and the variety of these declined from the beginning to the end of month period. Overall diet quality was poor among participants, with an average HEI-2015 score of 45.2 in the beginning of the month and 50.8 in the end of the month compared to the maximum possible score of 100. Analysis of functional MRI (fMRI) results demonstrated the feasibility of using functional neuroimaging techniques to evaluate individual differences in brain activation for palatable and healthy food images among participants. These findings suggest low-income women experience intra-monthly changes in variety of food available in the household and individual diet quality. And, investigations of intra-monthly changes in the home food environment, diet quality, and fMRI activation for visual food stimuli are important for understanding the relationship between food insecurity and obesity among low-income women. This work contributes to a greater understanding of the biobehavioral effects of food insecurity, which influence dietary intake and ultimately nutrition related health outcomes in those experiencing food insecurity."--Abstract from author supplied metadata

Book Description
At some point during 2009, more than 17 million households in the United States had difficulty providing enough food for all their members because of a lack of resources. In more than one-third of these households, the food intake of some household members was reduced and normal eating patterns were disrupted due to limited resources. The Workshop on Understanding the Relationship Between Food Insecurity and Obesity was held to explore the biological, economic, psychosocial, and other factors that may influence the relationship between food insecurity, overweight, and obesity in the United States. Hunger and Obesity examines current concepts and research findings in the field. The report identifies information gaps, proposes alternative approaches to analyzing data, recommends new data that should be collected, and addresses the limitations of the available research.

Book Description
We examine the extent to which food insecurity questions and the standard poverty measure are correlated with various dietary and physiologic outcomes. Our findings suggest that the correlations vary tremendously by age. We find that the food insecurity questions are correlated with the dietary outcomes of older household members, but that they are not consistently related to the diets of children. In contrast, poverty predicts dietary outcomes among preschoolers. Among adults, both poverty and food insecurity questions are good predictors of many dietary outcomes.
