Abstract
Food insecurity, defined by unpredictable access to food that may not meet a person's nutritional needs, is associated with higher BMI (kg/m2) and obesity. People with food insecurity often have less access to food, miss meals and go hungry, which can lead to psychological and metabolic changes that favor energy conservation and weight gain. We describe a conceptual model that includes psychological (food reinforcement and delay discounting) and physiological (thermic effect of food and substrate oxidation) factors to understand how resource scarcity associated with food insecurity evolves into the food insecurity-obesity paradox. We present both animal and human translational research to describe how behavioral and metabolic adaptations to resource scarcity based on behavioral ecology theory may occur for people with food insecurity. We conclude with ideas for interventions to prevent or modify the behaviors and underlying physiology that characterize the income-food insecurity-obesity relationship.

Abstract
Food insecurity is a major public health issue. Millions of households worldwide have intermittent and unpredictable access to food and this experience is associated with greater risk for a host of negative health outcomes. While food insecurity is a contemporary concern, we can understand its effects better if we acknowledge that there are ancient biological programs that evolved to respond to the experience of food scarcity and uncertainty, and they may be particularly sensitive to food insecurity during development. Support for this conjecture comes from common findings in several recent animal studies that have modeled insecurity by manipulating predictability of food access in various ways. Using different experimental paradigms in different species, these studies have shown that experience of insecure access to food can lead to changes in weight, motivation and cognition. Some of these studies account for changes in weight through changes in metabolism, while others observe increases in feeding and motivation to work for food. It has been proposed that weight gain is an adaptive response to the experience of food insecurity as 'insurance' in an uncertain future, while changes in motivation and cognition may reflect strategic adjustments in foraging behavior. Animal studies also offer the opportunity to make in-depth controlled studies of mechanisms and behavior. So far, there is evidence that the experience of food insecurity can impact metabolic efficiency, reproductive capacity and dopamine neuron synapses. Further work on behavior, the central and peripheral nervous system, the gut and liver, along with variation in age of exposure, will be needed to better understand the full body impacts of food insecurity at different stages of development.

Effects of Episodic Food Insecurity on Psychological and Physiological Responses in African American Women With Obesity (RESPONSES): Protocol for a Longitudinal Observational Cohort Study. JMIR Res Protoc 2023; 12:e52193. [PMID: 38117554 PMCID: PMC10765303 DOI: 10.2196/52193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 11/17/2023] [Accepted: 11/27/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND Food insecurity is a risk factor for multiple chronic diseases, including obesity. Importantly, both food insecurity and obesity are more prevalent in African American women than in other groups. Furthermore, food insecurity is considered a cyclic phenomenon, with episodes of food adequacy (ie, enough food to eat) and food shortage (ie, not enough food to eat). More research is needed to better understand why food insecurity is linked to obesity, including acknowledging the episodic nature of food insecurity as a stressor and identifying underlying mechanisms. OBJECTIVE The objective of this study is to investigate the episodic nature of food insecurity as a stressor via responses in body weight and psychological and physiological parameters longitudinally and do so in a health-disparate population-African American women. METHODS We enrolled 60 African American women (food-insecure cohort: n=30, 50%; food-secure cohort: n=30, 50%) aged 18-65 years with obesity (BMI 30-50 kg/m2) to measure (1) daily body weight remotely over 22 weeks and (2) psychological and physiological parameters via clinic assessments at the beginning and end of the 22-week study. Furthermore, we are assessing episodes of food insecurity, stress, hedonic eating, and appetite on a weekly basis. We hypothesize that food-insecure African American women with obesity will demonstrate increased body weight and changes in psychological and physiological end points, whereas food-secure African American women with obesity will not. We are also examining associations between changes in psychological and physiological parameters and changes in body weight and performing a mediation analysis on the psychological parameters assessed at the study midpoint. Psychological questionnaires are used to assess stress; executive function, decision-making, and motivation; and affect and nonhomeostatic eating. Physiological measurements are used to evaluate the levels of cortisol, dehydroepiandrosterone-sulfate (DHEA-S), C-reactive protein, thyroid hormones, blood glucose, glycated hemoglobin, and insulin, as well as allostatic load. RESULTS This study has completed participant recruitment (n=60). At the time of study enrollment, the mean age of the participants was almost 47 (SD 10.8) years, and they had a mean BMI of 39.6 (SD 5.31) kg/m2. All data are anticipated to be collected by the end of 2023. CONCLUSIONS We believe that this is the first study to examine changes in body weight and psychological and physiological factors in food-insecure African American women with obesity. This study has significant public health implications because it addresses the cyclic nature of food insecurity to identify underlying mechanisms that can be targeted to mitigate the adverse relationship between food insecurity and obesity and reduce health disparities in minority populations.

Abstract
Impulsive choice is preference for a smaller-sooner (SS) outcome over a larger-later (LL) outcome when LL choices result in greater reinforcement maximization. Delay discounting is a model of impulsive choice that describes the decaying value of a reinforcer over time, with impulsive choice evident when the empirical choice-delay function is steep. Steep discounting is correlated with multiple diseases and disorders. Thus, understanding the processes underlying impulsive choice is a popular topic for investigation. Experimental research has explored the conditions that moderate impulsive choice, and quantitative models of impulsive choice have been developed that elegantly represent the underlying processes. This review spotlights experimental research in impulsive choice covering human and nonhuman animals across the domains of learning, motivation, and cognition. Contemporary models of delay discounting designed to explain the underlying mechanisms of impulsive choice are discussed. These models focus on potential candidate mechanisms, which include perception, delay and/or reinforcer sensitivity, reinforcement maximization, motivation, and cognitive systems. Although the models collectively explain multiple mechanistic phenomena, there are several cognitive processes, such as attention and working memory, that are overlooked. Future research and model development should focus on bridging the gap between quantitative models and empirical phenomena.

Abstract
Most previous studies have shown that focusing on the future predicts higher subjective well-being (SWB), but some have reported contradictory results. Due to mixed findings on the relationship between time orientation (TO) and SWB, the present study attempted to clarify and reinterpret this relationship from a nonmonotonic perspective by analyzing two large-scale datasets from the European Social Survey (Study 1; 31 countries, total N = 88,873) and tested the cross-cultural generalizability of our findings in a Chinese sample (Study 2; N = 797). The results confirmed a nonmonotonic relationship between TO and SWB and first revealed a "Middle Valley Effect." This effect demonstrated a decreased SWB at the midpoint of the TO scale, indicating that maintaining a dominant TO, whether present or future, rather than being torn between the two, could improve SWB. This nonmonotonic relationship resolves previous inconsistent findings and suggests that an appropriate clear TO can benefit SWB.

Abstract
BACKGROUND Individuals with obesity tend to discount the future (delay discounting), focusing on immediate gratification. Delay discounting is reliably related to indicators of economic scarcity (i.e., insufficient resources), including lower income and decreased educational attainment in adults. It is unclear whether the impact of these factors experienced by parents also influence child delay discounting between the ages of 8 and 12-years in families with obesity. METHODS The relationship between indices of family income and delay discounting was studied in 452 families with parents and 6-12-year-old children with obesity. Differences in the relationships between parent economic, educational and Medicaid status, and parent and child delay discounting were tested. RESULTS Results showed lower parent income (p = 0.019) and Medicaid status (p = 0.021) were differentially related to greater parent but not child delay discounting among systematic responders. CONCLUSIONS These data suggest differences in how indicators of scarcity influence delay discounting for parents and children, indicating that adults with scarce resources may be shaped to focus on immediate needs instead of long-term goals. It is possible that parents can reduce the impact of economic scarcity on their children during preadolescent years. These findings suggest a need for policy change to alleviate the burden of scarce conditions and intervention to modify delay discounting rate and to improve health-related choices and to address weight disparities.

Abstract
Scarcity refers to a state in which an individual's resources do not satisfy his/her needs. A sense of scarcity evokes negative emotions. A fundamental strategy for coping with this negative threat is for people to emphasize the desirability of their personal traits. In this study, a 2 (sense of scarcity: high or low) × 2 (valence: positive or negative) mixed-design experiment was conducted to examine whether and how a sense of scarcity affected one's self-evaluation. Participants were assigned randomly to a high- or low-scarcity group. The chances of assistance rendered to an individual during a word puzzle task were manipulated to induce a high or low sense of scarcity. Then, participants were asked to make positive and negative trait judgments of themselves compared with their average peers. The results showed that people judged their personalities to be more desirable (i.e., more positive and less negative traits) than their average peers, manifesting the above-average effect. More importantly, people with a high sense of scarcity manifested a greater above-average effect than those with a low sense of scarcity. This study suggests that people could highlight their positive aspects to cope with predicaments in social life.

Abstract
Food insecurity, defined as unpredictable access to food that may not meet a person's nutritional needs, is paradoxically associated with higher BMI (kg/m2) and obesity. Research has shown delay discounting, a behavioral economic measure of the preference for immediate rather than delayed rewards, is related to higher BMI, and moderates the relationship between income and food insecurity. Based on this research, we used regression models to test whether delay discounting, consideration of future consequences, and perceived stress were atemporal mediators of the food insecurity-BMI relation in 313 mothers, controlling for demographic variables. A secondary aim was to replicate the finding that delay discounting moderates the relationship between low income and high food insecurity. Results showed that low income was associated with higher food insecurity, and higher food insecurity was associated with higher BMI. Delay discounting was the only variable that was indirectly related to both paths of the food-insecurity-BMI relation. Delay discounting accounted for 22.2% of the variance in the low-income-food insecurity-obesity relation, and the total model accounted for 38.0% of the variance. The relation between low income and food insecurity was moderated by delay discounting. These data suggest that delay discounting is a potential mediator of the relationship between food insecurity and high BMI, which suggests reducing discounting in the future could be a novel target to reduce food insecurity and help people with food insecurity to reduce their excess body weight.

Abstract
The COVID-19 pandemic provided an opportunity to investigate factors related to public response to public health measures, which could help better prepare implementation of similar measures for inevitable future pandemics. To understand individual and environmental factors that influence likelihood in engaging in personal and public health measures, three crowdsourced convenience samples from Amazon Mechanical Turk (MTurk) completed likelihood-discounting tasks of engaging in health behaviors given a variety of hypothetical viral outbreak scenarios. Experiment 1 assessed likelihood of mask wearing for a novel virus. Experiment 2 assessed vaccination likelihood based on efficacy and cost. Experiment 3 assessed likelihood of seeking health care based on number of symptoms and cost of treatment. Volume-based measures and three-dimensional modeling were used to analyze hypothetical decision making. Hypothetical public and personal health participation increased as viral fatality increased and generally followed a hyperbolic function. Public health participation was moderated by political orientation and trust in science, whereas treatment-seeking was only moderated by income. Analytic methods used in this cross-sectional study predicted population-level outcomes that occurred later in the pandemic and can be extended to various health behaviors.

Abstract
This study investigated the effects of experimentally manipulated scarcity on the reinforcing value of food (RRVfood) and delay discounting (DD), which, together, create reinforcer pathology (RP) among parents and offspring. A stratified sample of 106 families (53 parent/child aged 7−10 dyads & 53 parent/adolescent aged 15−17 dyads) from high- and low-income households visited our laboratory for three appointments. Each appointment included an experimental manipulation of financial gains and losses and DD and RRV tasks. The results showed that, regardless of food insecurity or condition, children had greater RP (β = 1.63, p < 0.001) than adolescents and parents. DD was largely unaffected by acute scarcity in any group, but families with food insecurity had greater DD (β = −0.09, p = 0.002) than food-secure families. Food-insecure parents with children responded to financial losses with an increase in their RRVfood (β = −0.03, p = 0.011), while food-secure parents and food-insecure parents of adolescents did not significantly change their responding based on conditions. This study replicates findings that financial losses increase the RRVfood among adults with food insecurity and extends this literature by suggesting that this is strongest for parents of children.

Abstract
BACKGROUND Delay Discounting is the extent to which one prioritizes smaller immediate rewards over larger, delayed rewards. The ability to prospect into the future is associated with better health decision-making, which suggests that delay discounting is an important intervention target for the prevention and treatment of chronic disease. Delay discounting decreases throughout development and stressful experiences, particularly those that accompany poverty, may influence this developmental trajectory. The current study leveraged the COVID-19 pandemic and resulting economic downturn as a natural experiment to understand how changes in food insecurity and psychological stress may associated with changes in delay discounting among parents, adolescents, and children. METHODS A stratified cohort of families (N = 76 dyads), established prior to the initial pandemic lockdowns, were asked to complete a follow-up survey in the summer of 2020, during reopening. Thirty-seven (49%) families had an older adolescent (aged 15 - 18 years) in the study and 39 (51%) had an elementary aged child (aged 7 - 12 years) in the follow-up study. Both data collection points included measurements of economic position, psychological stress, food security status, and delay discounting. RESULTS The results showed that pandemic food insecurity was associated with greater stress among parents (β = 2.22, t(65.48) = 2.81, p = 0.007). Parents, Adolescents, and children significantly differed in their response to psychological stress during the pandemic (β = -0.03, t(102.45) = -2.58, p = 0.011), which was driven by a trend for children to show greater delay discounting associated with an increase in psychological stress during the pandemic (β = -0.01, p = 0.071), while adolescents and parents showed no change. CONCLUSIONS These findings add to the evidence that food insecurity is uniquely stressful among parents with no effects on delay discounting. Despite this, we found no evidence that food insecurity was stressful for child or adolescents. A trend in our data suggested that childhood, as compared with adolescence, may be an important developmental period for the association between stress and delay discounting. Future research should continue the longitudinal investigation of childhood stress and the developmental trajectory of delay discounting to ascertain how these effects may persist in adulthood.

Inhibitory control within the context of early life poverty and implications for outcomes. Neurosci Biobehav Rev 2022; 140:104778. [PMID: 35843346 DOI: 10.1016/j.neubiorev.2022.104778] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 07/11/2022] [Accepted: 07/12/2022] [Indexed: 11/24/2022]
Abstract
Early life poverty confers risk for unfavorable outcomes including lower academic achievement, behavioral difficulties, and neurodevelopmental disorders. Disruptions in inhibitory control (IC) have been posed as one mechanism to explain the relationship between early life poverty and deleterious outcomes. There is robust research to suggest that early life poverty is associated with development of poorer IC. Further, poorer IC in children is related to decreased academic achievement and social competence, and increased externalizing and internalizing behavior. There is some parent-report evidence to suggest that IC is a mediator of the relationship between poverty and externalizing behaviors, as well as some limited evidence to suggest that IC is a mediator between poverty and academic achievement. Future work should aim to determine whether early life poverty's relation to IC could be explained by verbal ability which is thought to be central to the development of effective IC. In addition, future neuroimaging work should utilize IC fMRI tasks to identify key neural mechanisms that might contribute to a relationship between early life poverty and IC.

Abstract
BACKGROUND The COVID-19 pandemic and countrywide lockdown could negatively impact household food insecurity among low-income households. This study aimed to investigate the prevalence of household food insecurity and its influencing factors among low-income people in Bangladesh during the lockdown of COVID-19. METHODS This cross-sectional study was conducted through face-to-face interviews from 500 low-income households during the countrywide COVID-19 lockdown. A pretested, structured and validated questionnaire was used to collect socioeconomic characteristics, household income conditions, and food accessibility. Household Food Insecurity Access Scale (HFIAS) and Dietary Diversity Score (DDS) were used to measure food insecurity. Multinomial logistic regression models were estimated to evaluate and predict risk factors that influence food insecurity. RESULTS The study found that above 67% of households was mild-to-moderate food insecure while 23% experienced severe food insecurity. Significantly, 88%, 97.4%, and 93.4% of the households had anxiety and uncertainty, inadequate quality, and inadequate quantity of food, respectively. The regression analysis revealed the age 36-50 years (RRR: 4.86; 95% CI: 2.31-7.44, RRR: 4.16; 95% CI: 2.25-6.10) and monthly income <58.3 USD (RRR: 3.04; 95% CI: 1.12-5.14, RRR: 3.26; 95% CI: 1.79-4.71) were significantly associated with food insecurity (p <0.001). Likewise, less-income (RRR: 3.87; 95% CI: 1.37-6.46, RRR: 2.99; 95% CI: 1.16-4.83), increase in food prices (RRR: 1.29; 95% CI: 0.32-2.33, RRR: 1.08; 95% CI: 0.05-1.12), and those who did not have same type of earning as before during the COVID-19 lockdown (RRR: 3.41; 95% CI: 1.33-5.62, RRR: 2.60; 95% CI: 0.99-4.24) were potential risk factor for MMFI and FI. CONCLUSION This study found that households become more susceptible to food insecurity during the COVID-19 pandemic and lockdown period. Based on the findings, we suggest some essential food policies and adequate food assistance to mitigate these negative consequences.

Abstract
BACKGROUND Food insecurity, obesity, and psychological stress are interrelated constructs which are thought to be connected through increased energy intake, but the underlying mechanisms for these relationships remain unclear. The current study used experimental methods to investigate how financial losses may influence acute stress in the context of food insecurity for both parents and offspring. This study also sought to examine the effect of acute stress related to financial losses on the reinforcing value of food (RRVfood) and delay discounting (DD). METHODS One hundred and six families stratified by both offspring age (53 children aged 7-10, 53 adolescents aged 15-17) and household financial resources, visited our laboratory for three separate appointments. Each appointment included the experimental manipulation of financial gains and losses, saliva samples for cortisol assay, continuous heart rate monitoring, self-rated tension, and computer-based DD and RRVfood tasks. Participants also completed surveys to report perceived life stress level and food insecurity status. RESULTS Among all participants, financial losses were related to decreased heart rates and increased self-rated tension. Among parents reporting food insecurity, acute financial losses resulted in an increase in cortisol levels. Changes in cortisol, heart rate, and tension were not related to RRVfood or DD. CONCLUSION Food insecure parents are sensitive to financial losses and respond with an increase in cortisol. However, we found no evidence for a relationship between cortisol and RRVfood or DD. This sensitivity to financial losses did not extend to children or adolescents.

Sensitization of the reinforcing value of high energy density foods is associated with increased zBMI gain in adolescents. Int J Obes (Lond) 2021; 46:581-587. [PMID: 34848836 PMCID: PMC8631696 DOI: 10.1038/s41366-021-01007-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 10/12/2021] [Accepted: 10/15/2021] [Indexed: 11/22/2022]
Abstract
Background/Objectives Characterizing behavioral phenotypes that predict increased zBMI gain during adolescence could identify novel intervention targets and prevent the development of obesity. The purpose of this study was to determine if sensitization of the relative reinforcing value (RRV) of high (HED) or low energy density (LED) foods predicts adolescent weight gain trajectories. A secondary aim was to test the hypothesis that relationships between sensitization of the RRV of food and weight change are moderated by delay discounting (DD). Subjects/Methods We conducted a prospective, longitudinal cohort study in 201 boys and girls with an average zBMI of 0.4, who began the study between the ages of 12 and 14 years and completed the study 2 years later. Participants completed five laboratory visits where the RRV of HED and LED, and DD were assessed at a baseline (visits 1, 2, and 4) and then RRV was measured again after participants consumed a portion of the same HED and LED food for 2 weeks (visits 3 and 5; order counterbalanced). Increases (>1) in the RRV from baseline to post-daily intake were categorized as “sensitization” and decreases (≤1) were categorized as “satiation.” Participants returned to the laboratory for follow-up visits at 6, 15, and 24 months to have height and weight taken and to complete additional assessments. Results Sensitization to HED food was associated with a greater zBMI change over time (β = 0.0070; p = 0.035). There was no impact of sensitization to LED food or interaction between sensitization to HED and LED food on zBMI change and no moderation of DD on the relationship between HED sensitization and zBMI change (all p > 0.05). Conclusion Our prior work showed that sensitization to HED food is cross-sectionally associated with greater zBMI. This study extends this work by demonstrating that sensitization to HED food prospectively predicts increased zBMI gain over time in adolescents without obesity. Future studies should determine if sensitization can be modified or reduced through behavioral intervention. Trial registration Clinicaltrials.gov: NCT04027608.

Abstract
Although obesity is a result of processes operating at multiple levels, most forms result from decision-making behavior. The aim of this review was to examine the candidacy of temporal discounting (TD) (i.e. the reduction in the value of a reinforcer as a function of the delay to its receipt) as a behavioral marker of obesity. For this purpose, we assessed whether TD has the ability to: identify risk for obesity development, diagnose obesity, track obesity progression, predict treatment prognosis/outcomes, and measure treatment effectiveness. Three databases (Pubmed, PsycINFO, and Web of Science) were searched using a combination of terms related to TD and obesity. A total of 153 papers were reviewed. Several areas show strong evidence of TD's predictive utility as a behavioral marker of obesity (e.g., distinguishing obese from non obese). However, other areas have limited and/or mixed evidence (e.g., predicting weight change). Given the positive relationship for TD in the majority of domains examined, further consideration for TD as a behavioral marker of obesity is warranted.

Abstract
OBJECTIVES The relation between food insecurity (FI) and delay discounting (DD) and probability discounting (PD) for food and money was tested in women. In addition, discounting was tested as a variable that mediates the relation between obesity and FI. METHOD Women recruited from a community sample (N = 92) completed questionnaires. They completed the food choice questionnaire, the monetary choice questionnaire, measures for food and money probability discounting (which quantify sensitivity to risk aversion), and demographic measures. RESULTS Women with FI had higher rates of obesity and higher food DD compared to food-secure women. However, DD for money or probability discounting for food or money did not significantly differ between FI and food secure groups when controlling for significant covariates. Neither DD or PD significantly mediated the relation between FI and obesity. CONCLUSIONS These results suggest that FI is associated with greater impulsive food choice, but its association with other monetary discounting and probability discounting for food and money appears contingent upon other demographic factors.

Abstract
The majority of people with prediabetes transition to type 2 diabetes. Research has suggested that persons with type 2 diabetes are likely to discount the future and focus on immediate rewards. This study was designed to assess whether this process of delay discounting (DD) is associated with glycemic regulation, medication adherence and eating and exercise behaviors in adults with prediabetes. Participants included 81 adults with prediabetes who were also prescribed hypertension or dyslipidemia drugs, which is common for people with prediabetes. Participants completed adjusting amount DD $100 and $1000 tasks, as well assessments of glycemic control (Hemoglobin (Hb) A1c), medication adherence, diet quality, and objectively measured physical activity. Relationships between DD and these variables were assessed. Results showed higher rates of DD were related to higher HbA1c; as well as poorer medication adherence, lower diet quality and lower physical activity. Hierarchical regression showed that the association between minority status, a known risk factor for type 2 diabetes, was moderated by DD, as minorities with higher DD had greater HbA1c values. Delay discounting may represent a novel target to prevent progression from prediabetes to type 2 diabetes.

Abstract
Rates of food insecurity have increased substantially in the United States (US), and more families are turning to the charitable food system to help meet their needs. Prior studies have examined the nutritional quality of foods offered through food banks, but little is known about what government policies may shape the healthy food donation landscape. The purpose of this study was to review US federal policies that impact food and beverage donations to food banks and assess whether policies encourage healthy food donations. In spring 2020, two researchers independently reviewed federal food and beverage donation policies using predefined search terms in two legal databases. We identified six categories of policies based on the existing food donation literature and themes that emerged in the policy review. We identified 42 federal policies spanning six categories that addressed food and beverage donations to food banks. The largest category was "government programs," with 19 (45%) policies. The next largest category was "donation via schools," with 12 (29%) policies. However, no policies specifically addressed the nutritional quality of food donations. There is an opportunity for the federal government to strengthen food bank donation policies and improve the nutritional quality of donated foods and beverages.

Abstract
OBJECTIVE This study examined psychological constructs (delay discounting, grit, future time perspective and subjective social status) in relation to food security status and body weight. DESIGN A simultaneous triangulation mixed methods design was used to collect quantitative and qualitative data. Quantitative data were collected in fifty-six adults. Independent variables included food security status (food secure or food insecure) and BMI category (normal weight or overweight/obese). Participants, matched on race (African American and White), were categorised into four food security status by BMI category groups. Psychological constructs were measured via validated questionnaires. Qualitative data were collected in a subsample of twelve participants via in-depth interviews. SETTING This study was conducted in Baton Rouge, Louisiana. PARTICIPANTS The sample was 66 % female and 48 % African American with a mean age of 32·3 (sd 9·2) years and BMI of 28·8 (sd 7·7) kg/m2. RESULTS Quantitative results showed that food-insecure participants with overweight/obesity had greater delay discounting (-3·78 v. -6·16, P = 0·01; -3·78 v. -5·75, P = 0·02) and poorer grit (3·37 v. 3·99, P = 0·02; 3·37 v. 4·02, P = 0·02 ) than their food-secure counterparts and food-insecure participants with normal weight. Food-insecure participants with overweight/obesity also had a shorter time period for financial planning (0·72 v. 4·14, P = 0·02) than food-secure participants with normal weight. Qualitative data largely supported quantitative findings with participants discussing varied perceptions of psychological constructs. CONCLUSIONS This study found differences in delaying gratification, grit and financial planning between food security status and body weight groups.

Abstract
BACKGROUND Adequate nutrition is essential during the lactation period for better maternal and child health outcomes. Although food insecurity and dietary monotony (defined as less diverse diet), two important determinants of undernutrition, are endemic in the rural mountains of Nepal, insufficiently examined and assessed for risk factors in mothers during lactation, a life stage of high nutritional demand. This study aimed to assess the status and factors associated with food insecurity and dietary diversity among lactating mothers residing in the mountains of Nepal. METHODS A community-based cross-sectional study was conducted in an urban municipality in the mountainous Bajhang District of far-western Nepal. The sampling frame and strategy led to 417 randomly selected lactating mothers. Household Food Insecurity Access Scale (HFIAS) and the tool "Minimum Dietary Diversity for Women" developed by the Food and Agriculture Organization were used to measure food insecurity and dietary diversity, respectively. Additional information on socio-demographics and risk factors were collected. Multivariable logistics regression assessed correlates of study outcomes. RESULTS Overall, 54% of the households were food insecure, and over half (53%) of the mothers had low dietary diversity. Food insecurity status (mild food insecurity AOR = 10.12, 95% CI = 4.21-24.34; moderate food insecurity AOR = 8.17, 95% CI = 3.24-20.59, and severe food insecurity AOR = 10.56, 95% CI = 3.92-28.43) were associated with higher odds of dietary monotony. Likewise, participants with lower dietary diversity were 8.5 times more likely to be food insecure than those with higher dietary diversity (AOR = 8.48, 95% CI = 3.76-19.14). The monthly income of the family was positively associated with food insecurity. Participants' (AOR = 3.92 95%CI = 1.76-8.71) or spouses' (AOR = 2.90, 95% CI = 1.07-7.85) unemployment was associated with higher odds of being food insecure. Likewise, owning a cultivable land (AOR = 0.49, 95% CI = 0.28-0.84) and participant's unemployment status (AOR = 5.92, 95% CI = 3.02-11.63), were significantly associated with increased odds of dietary monotony. CONCLUSION The observed food insecurity and poor dietary diversity among lactating mothers, the correlates associated with these outcomes, may help local stakeholders to identify local health needs and subgroups for targeted interventions. Socioeconomically disadvantaged mothers should be specifically targeted for relevant programs and policies.

Abstract
Shame and guilt are responses to moral transgressions that are characterized by negative self-evaluations and negative behavioral-evaluations, respectively. Previous research has found shame to be the more maladaptive of these “self-conscious” emotions due to its association with various health-risk behaviors. In the current study, undergraduate participants (n = 199) from a large, public university completed behavioral and self-report measures of impulsivity, shame and guilt-proneness, and behavioral tendencies. Exploratory factor analysis and mediation models were used to determine if shame and/or guilt-proneness significantly mediate the relationship between impulsivity and internalized/externalized problems. Findings demonstrate that impulsivity and shame proneness both positively predict internalized and externalized problem behavior, but indirect effects of shame and guilt are not significant. These findings indicate that shame and guilt do not reliably mediate the relationship between impulsivity and problem behavior, but they do support previous findings on the maladaptive nature of impulsivity and shame. Implications for the protective nature of guilt proneness are also discussed.

Abstract
ABSTRACT
Background
Federal food assistance programs target low-income and nutritionally vulnerable Americans, with the dual goals of reducing food insecurity and improving diet quality. Individuals on limited food budgets may face constraints on their ability to purchase healthy foods when their prices increase, which could mitigate the intended impact of federal feeding programs. To better understand the effect of food price changes on healthy food purchases, we focus on eggs, which are rich in many important nutrients and can be a healthy part of a wide range of cultural food menus.
Objective
We use a laboratory-based grocery store experiment (n = 80) to examine the difference in price elasticity of eggs between individuals participating in food assistance programs and those not participating in these programs. This trial was registered at clinicaltrials.gov as NCT03296878.
Methods
Subjects completed several food purchasing trials, as well as questionnaires that assessed demographic, psychosocial, and other factors. Mixed linear regression models were used to assess the relationship between food price changes and food purchases (price elasticity).
Results
No difference in price elasticity was observed between groups, but subjects in both groups decreased their egg purchases by 6.9–8.6% for every 10% increase in egg price. For every 10% increase in the price of all nonegg foods, egg purchases increased by 3.3% among federal food assistance program participants but not nonparticipants, and purchases for foods such as lean meats, low-fat dairy, fruits, vegetables, and whole grains decreased by up to 14% among both groups.
Conclusions
Efforts to emphasize healthy eating strategies for individuals on limited budgets will be especially important during times of food price increases. Additional research is needed to estimate the price elasticities of other food groups among individuals participating in federal food assistance programs.

Abstract
OBJECTIVE To identify the prevalence and demographic characteristics of food insecurity in a presurgical bariatric population. To date there has been no research on food insecurity in a presurgical bariatric population. DESIGN Participants completed the ten-item adult food security survey module created by the US Department of Agriculture (USDA), with additional questions related to food shopping behaviours and perceived affordability of post-bariatric supplements. USDA scoring guidelines were used to classify participants as food secure, marginally food secure and food insecure. SETTING Academic medical centre bariatric surgery clinic in Central Pennsylvania, USA. PARTICIPANTS Adult bariatric surgery candidates (n 174). RESULTS There was a prevalence of 17·8 % for food insecurity and 27·6 % for marginal food security. Food insecurity was associated with younger age, higher BMI, non-White race/ethnicity, having less than a college education, living in an urban area, receiving Medicaid/Medicare and participating in nutrition assistance programmes. Food-insecure participants endorsed food shopping behaviours that could interfere with postsurgical dietary adherence and perceived post-bariatric supplies as unaffordable or inaccessible. CONCLUSIONS These results highlight the importance of screening bariatric surgical patients for food insecurity. Further study of this important problem within the bariatric population should address effects of food insecurity and related shopping behaviours on postsurgical outcomes and inform the development of programmes to better assist these high-risk patients.

Abstract
BACKGROUND Food insecurity, defined as inconsistent food access owing to cost, leads to poor health. OBJECTIVE To test whether a medically tailored meal delivery program improved dietary quality in individuals with type 2 diabetes and food insecurity. DESIGN Randomized cross-over clinical trial. PARTICIPANTS Forty-four adults with diabetes, hemoglobin A1c > 8.0%, and food insecurity (defined as at least one positive item on the two-item "Hunger Vital Sign"). INTERVENTION In the Community Servings: Food as Medicine for Diabetes cross-over clinical trial (NCT02426138), conducted from June 2015 to July 2017, we randomly assigned the order of "on-meals" (home delivery of 10 meals/week for 12 weeks delivered by Community Servings, a non-profit organization) and "off-meals" (12 weeks usual care and a Choose MyPlate healthy eating brochure) periods. MAIN MEASURES The primary outcome was Healthy Eating Index 2010 score (HEI), assessed by three 24-h food recalls in both periods. Higher HEI score (range 0-100; clinically significant difference 5) represents better dietary quality. Secondary outcomes included food insecurity and self-reported hypoglycemia. KEY RESULTS Mean "on-meal" HEI score was 71.3 (SD 7.5) while mean "off-meal" HEI score was 39.9 (SD 7.8) (difference 31.4 points, p < 0.0001). Participants experienced improvements in almost all sub-categories of HEI score, with increased consumption of vegetables, fruits, and whole grains and decreased solid fats, alcohol, and added sugar consumption. Participants also reported lower food insecurity (42% "on-meal" vs. 62% "off-meal," p = 0.047), less hypoglycemia (47% "on-meal" vs. 64% "off-meal," p = 0.03), and fewer days where mental health interfered with quality of life (5.65 vs. 9.59 days out of 30, p = 0.03). CONCLUSIONS For food-insecure individuals with diabetes, medically tailored meals improved dietary quality and food insecurity and reduced hypoglycemia. Longer-term studies should evaluate effects on diabetes control (e.g., hemoglobin A1c) and patient-reported outcomes (e.g., well-being).

Abstract
OBJECTIVES Food insecurity, limited or uncertain access to adequate nutrition, is an increasingly recognized determinant of health outcomes and is often associated with having obesity. It is unclear, however, if this association persists in elderly populations. METHODS We conducted a cross-sectional study of 2868 participants' aged 65+ years from the Health and Retirement Study. Multivariate logistic regression was used to assess associations between food insecurity and body mass index, demographic characteristics, psychiatric history, and medical history. RESULTS Participants with overweight/obesity had a higher prevalence of food insecurity than leaner counterparts, however, weight status was not a significant predictor of food insecurity after multivariate adjustment. Instead, mental illness, current smoking status, and non-White race were all independently associated with food insecurity. DISCUSSION Beyond financial status, health care providers are encouraged to use these characteristics to identify elderly patients that may be at risk of food insecurity.

Abstract
Fixating on the present moment rather than considering future consequences of behavior is considered to be a hallmark of drug addiction. As an example, cigarette smokers devalue delayed consequences to a greater extent than nonsmokers, and former smokers devalue delayed consequences more than nonsmokers, but less than current smokers. Further, cigarette smokers have higher norepinephrine levels than nonsmokers, which is indicative of poor future health outcomes. It is unclear how duration of cigarette smoking may impact these associations. The current secondary analysis of publicly available data investigated whether extent of future thinking is associated with smoking duration, as well as norepinephrine level, in a large national US sample (N = 985) of current, former, and never smokers. Individuals scoring lower on future thinking tended to smoke for longer durations and had higher norepinephrine levels relative to individuals scoring higher on future thinking. In addition, duration of cigarette abstinence interacted significantly with future thinking and smoking duration for former smokers. Specifically, the mediation relationship between future thinking, smoking duration, and norepinephrine level for former smokers was strongest at shorter durations of cigarette abstinence and decreased as a function of increasing duration of cigarette abstinence. Overall, results from this study suggest the potential importance of implementing smoking cessation treatments as early as possible for smokers and support future thinking as a potential therapeutic target for smoking cessation treatment.

Abstract
Two studies examined whether episodic future thinking (EFT; pre-experiencing future events) reduces discounting of future rewards (DD). No studies have investigated whether process simulations (i.e., simulating the process of executing a future event) amplify EFT's reduction of DD. Study 1 examined the effect of incorporating process simulations into EFT (N = 42, M age = 43.27; 91% female, family income = $75,976) using a 2 × 2 factorial design with type of episodic thinking (process, nonprocess/general) and temporal perspective (EFT, episodic recent thinking) as between-subjects factors. Study 2 replicated Study 1 in a sample of adults living in poverty (N = 36; M age = 38.44, 88% female; family income = $25,625). The results of both studies showed EFT reduced DD, but process-oriented EFT did not amplify the effect of EFT. Our findings suggest the key ingredient in EFT's effect on DD is self-projection into the future. This was also the first study to show EFT improves DD in a sample living in poverty.

Abstract
We present a protocol for a study investigating the effect of food price changes on purchasing decisions among individuals participating in federal food assistance programs and among those not participating in these programs. We use a laboratory-based grocery store design, which provides greater control over factors influencing food purchasing than in situ experiments in actual grocery stores. We focus primarily, but not exclusively, on eggs because they are highly nutritious, easy to prepare, can be included in many different dishes, and are a part of a wide range of cultural food menus. The primary aim of this study is to compare the own-and cross-price elasticity of eggs between individuals participating in federal food assistance programs and those not participating in these programs. Our secondary aims are to 1) compare the own- and cross-price elasticity of eggs between overweight/obese individuals and non-overweight/obese individuals, 2) examine whether delay discounting moderates the effect of income on own- and cross-price elasticity, 3) examine whether subjective social status moderates the effect of participation in federal food assistance programs on the purchase of high nutrient-dense foods, and 4) examine whether usual psychological stress level moderates the effect of subjective social status on the purchase of high-nutrient dense foods. The results of this study will provide information about the drivers of food demand among low-income adults. A better understanding of these drivers is needed to develop effective nutrition interventions for this large population.

Abstract
Obesity is associated with steep discounting of the future and increased food reinforcement. Episodic future thinking (EFT), a type of prospective thinking, has been observed to reduce delay discounting (DD) and improve dietary decision making. In contrast, negative income shock (i.e., abrupt transitions to poverty) has been shown to increase discounting and may worsen dietary decision-making. Scalability of EFT training and protective effects of EFT against simulated negative income shock on DD and demand for food were assessed. In two experiments we showed online-administered EFT reliably reduced DD. Furthermore, EFT reduced DD and demand for fast foods even when challenged by negative income shock. Our findings suggest EFT is a scalable intervention that has implications for improving public health by reducing discounting of the future and demand for high energy dense food.

Abstract
Steep discounting of delayed rewards is linked with a variety of unhealthy behaviors that contribute to the major causes of preventable death and disease. Growing evidence suggests that decreases in delay discounting contribute to healthier preferences. This study sought to provide preliminary evidence for the viability of developing a brief priming task to reduce delay discounting in a large, diverse group of individuals. Participants (n=1,122) were randomized to one of three conditions: Future Focus (FF), Present Focus (PF), and Non-Temporal Focus (NTF) intended respectively to decrease, increase, or have no effect on delay discounting. Participants then completed the Monetary Choice Questionnaire, a brief assessment of delay discounting rate. Participants randomized to FF exhibited significantly lower discounting rates than those randomized to PF or NTF conditions. Race, Hispanic background, social self-monitoring, education, and cigarette smoking also accounted for a significant amount of variance in the discounting model. These findings provide support for the development of a brief priming intervention that might be examined in clinical or public health contexts to decrease discounting and support healthy choices.

Abstract
BACKGROUND Sex-related alcohol expectancies reflect the degree to which a person believes alcohol will affect her or his sexual behavior. Sex-related alcohol expectancies have been found to be predictors of drinking in sexual situations and engagement in risky sexual behavior after drinking. However, less is known about individual characteristics that may moderate these associations. Building upon recent evidence that steep delay discounting is associated with alcohol-related sexual risk taking, this study aimed to test the hypothesis that the associations between sex-related alcohol expectancies and alcohol-related sexual risk taking would be stronger among individuals who discount delayed rewards more steeply. METHODS The current sample comprised 126 Emergency Department patients (Mage = 27.37; 55% male) who reported high-risk alcohol use and sexual behavior during the past 3 months. Sex-related alcohol expectancies were assessed in 3 behavioral domains: increased riskiness, decreased nervousness, and enhanced sexuality. RESULTS All 3 expectancy domains were associated with quantity and frequency of alcohol use, as well as percentage of alcohol-related condomless sex. Delay discounting moderated 2 of these relationships, such that the associations between expectancies for alcohol-induced sexual risk taking and the enhancement of sexuality and percentage of alcohol-related sexual risk-taking were significantly stronger in individuals who exhibited steeper delay discounting. CONCLUSIONS These findings suggest that individuals who both discount delayed rewards more steeply and hold strong sex-related alcohol expectancies are a particularly high-risk population. Such individuals may benefit from a combination of novel preventive strategies targeting sex-related alcohol expectancies and impulsive decision making.

Abstract
Objective The objective of this study was to examine how sensitivity to short‐term reward and long‐term goal perseverance are related to body mass index (BMI; kg m2) in a large sample of men and women with and without obesity. Methods A total of 450 participants (56.2% male; 73.1% non‐Hispanic White) with mean ± standard deviation age of 30.7 ± 10.4 years and BMI of 29.3 ± 8.2 completed online versions of the Delayed Reward Discounting task to measure sensitivity to short‐term reward and the Grit Scale to measure long‐term goal perseverance. Results In regression analysis, higher sensitivity to short‐term reward (i.e. a preference for receiving smaller rewards after a shorter delay; b = 0.49, p = 0.016) and lower long‐term goal perseverance (b = −1.26, p = 0.042) were independently associated with higher BMIs. Individuals with a favourable score on one measure were not ‘protected’ from the risk associated with an unfavourable score on the other measure. Conclusions An overvaluation of short‐term reward (e.g. the taste of palatable food and the comfort of engaging in sedentary activities) and undervaluation of long‐term health goals (e.g. achieving a healthy weight and avoiding obesity‐related comorbidities) may contribute to excess weight. Additional research incorporating prospective experimental designs is needed to determine whether decision‐making strategies can be targeted to improve weight management.

Abstract
Humans are reported to discount delayed rewards at lower rates than nonhumans. However, nonhumans are studied in tasks that restrict reinforcement during delays, whereas humans are typically studied in tasks that do not restrict reinforcement during delays. In nonhuman tasks, the opportunity cost of restricted reinforcement during delays may increase delay discounting rates. The present within-subjects study used online crowdsourcing (Amazon Mechanical Turk, or MTurk) to assess the discounting of hypothetical delayed money (and cigarettes in smokers) under four hypothetical framing conditions differing in the availability of reinforcement during delays. At one extreme, participants were free to leave their computer without returning, and engage in any behavior during reward delays (modeling typical human tasks). At the opposite extreme, participants were required to stay at their computer and engage in little other behavior during reward delays (modeling typical nonhuman tasks). Discounting rates increased as an orderly function of opportunity cost. Results also indicated predominantly hyperbolic discounting, the "magnitude effect," steeper discounting of cigarettes than money, and positive correlations between discounting rates of these commodities. This is the first study to test the effects of opportunity costs on discounting, and suggests that procedural differences may partially account for observed species differences in discounting.
