Red meat production is a leading contributor to food-related greenhouse gas emissions. Decreasing red meat intake can mitigate climate change and lower risk of diet-related diseases.The goal of this study is to evaluate university students' perceptions of climate-friendly behaviors and to assess how these perceptions are associated with the frequency of red meat intake.Cross-sectional survey SETTING: A large, public California university and a large, public Michigan university PARTICIPANTS: Undergraduate students from a California university (n = 721) and a Michigan university (n = 568) MAIN OUTCOME MEASURES: Perceptions of climate-friendly behaviors and frequency of red meat intake STATISTICAL ANALYSIS: Differences in perceptions by student characteristics were compared using t-tests and one-way analysis of variance. Associations between perceptions of climate-friendly behaviors and red meat intake frequency were examined using generalized linear models, adjusted for sociodemographic covariates.Across both universities, students rated reducing meat intake as less effective than other climate change mitigation behaviors such as recycling and using less plastic. However, students who reported (1) making food and beverage choices that "are good for the environment," (2) making food and beverage choices that "reduce climate change impact," or (3) agreeing that "eating less meat is an effective way to combat climate change" reported 10% to 25% lower frequency of red meat intake for each point higher on the agreement scale. In contrast, making food and beverage choices motivated by health was not associated with frequency of red meat intake.Sustainability motivations and perceptions of meat's climate impact were associated with lower frequency of red meat intake, despite the overall moderate rating of eating less meat as an effective climate change mitigator. This research lends support to behavioral interventions, public education campaigns, and policies aiming to reinforce sustainable dietary patterns in young adults.

BackgroundHousehold food insecurity persists in the United States and has important implications for health and well-being. Food insecurity in female-identified caregivers is particularly concerning, given its association with their mental health and adverse health outcomes for their children. Food insecurity is associated with disordered eating but, to our knowledge, no prior studies have examined an association between food insecurity and food addiction.ObjectiveOur aim was to examine whether food insecurity is associated with higher food addiction symptom endorsement in low-income female adults.DesignSecondary analysis of baseline data from a quasi-experimental study of a mindfulness-based intervention on gestational weight gain among low-income pregnant individuals and an observational study of low-income families.Participants/settingParticipants in study 1 (n= 208) were English-speaking, low-income pregnant individuals with overweight or obesity, recruited in California from 2011 to 2013. Participants in study 2 (n= 181) were English-speaking, low-income female caregivers for children aged 8 through 10 years, recruited in Michigan from 2018 to 2019. Both studies recruited participants from community health clinics, social service agencies, and online advertisements.Main outcome measuresThe primary outcome measure was food addiction symptoms, assessed by the Yale Food Addiction Scale.Statistical analysisMultivariate Poisson regression was used to examine the association between household food insecurity and food addiction symptoms in each sample, adjusted for sociodemographic characteristics.ResultsIn study 1, pregnant individuals in food-insecure households reported 21% higher food addiction symptoms than pregnant individuals in food-secure households (incidence rate ratio 1.21; 95% CI 1.00 to 1.47; P= .047). In study 2, caregivers in food-insecure households had 56% higher food addiction symptoms than caregivers in food-secure households (incidence rate ratio 1.56; 95% CI 1.01 to 2.40; P= .045).ConclusionsThese findings provide preliminary support for a relationship between household food insecurity and food addiction. Future research should examine potential mechanisms and whether interventions to reduce food insecurity lower risk of food addiction.

BACKGROUND: Ultra-processed foods contribute to risks of obesity and cardiometabolic disease, and higher intakes have been observed in low-income populations in the United States. Consumption of ultra-processed foods may be particularly higher among individuals experiencing food insecurity and participating in the Supplemental Nutrition Assistance Program (SNAP). OBJECTIVES: Using data from the 2007–2016 NHANES, we examined the associations between food insecurity, SNAP participation, and ultra-processed food consumption. METHODS: The study population comprised 9190 adults, aged 20–65 y, with incomes ≤300% of the federal poverty level (FPL). Food insecurity was assessed using the Household Food Security Survey Module and SNAP participation over the past 12 mo was self-reported. Dietary intake was measured from two 24-h dietary recalls. Ultra-processed food consumption (percentage of total energy intake) was defined using the NOVA food classification system. Linear regression models were used to examine the associations between food insecurity, SNAP participation, and ultra-processed food consumption, adjusting for sociodemographic and health characteristics. RESULTS: More severe food insecurity was associated with higher intakes of ultra-processed foods (P-trend = 0.003). The adjusted means of ultra-processed food intake ranged from 52.6% for adults with high food security to 55.7% for adults with very low food security. SNAP participation was also associated with higher intakes of ultra-processed foods (adjusted mean: 54.7%), compared with income-eligible participants (adjusted mean: 53.0%). Furthermore, the association between food insecurity and ultra-processed foods was modified by SNAP participation (P-interaction = 0.02). Among income-eligible nonparticipants and income-ineligible nonparticipants, more severe food insecurity was associated with higher consumption of ultra-processed foods. Among SNAP participants, the association between food insecurity and consumption of ultra-processed foods was nonsignificant. CONCLUSION: In a nationally representative sample of adults, food insecurity and SNAP participation were both associated with higher levels of ultra-processed food consumption.

Objective How does diet quality (DQ) moderate associations between serious childhood stress exposures and adult depression? Methods We analyzed a cohort of Californian women at midlife (N=382; age 36-42). Serious childhood stress was defined as high perceived stress during childhood or adverse childhood experiences (ACEs) of physical abuse, sexual abuse, and/or household substance abuse. Women were dichotomized by current depression risk (high/low). The Healthy Eating Index (HEI)-2015 and Alternate Healthy Eating Index (AHEI)-2010 measured current DQ from 3-day food records. Interactions between childhood stress exposures and DQ indices were tested one-by-one in multivariable Poisson regression models. Results Depression risks associated with endorsing all 3 ACEs differed by HEI and AHEI scores, as did risks associated with endorsing high perceived stress, physical abuse, and sexual abuse by AHEI. Where DQ moderated stress-depression associations, predicted prevalences of high depression risk did not vary with DQ among women endorsing the particular childhood stressors. However, among non-endorsing women, predicted high depression risk prevalences were significantly lower with higher DQ compared to in their stress-exposed counterparts - e.g. at the 90th AHEI percentile, depression prevalences were ∼20% among 'non-childhood-stressed' women versus 48.8% (high perceived stress, sexual abuse), 52.0% (physical abuse), and 73.0% (3 ACEs) in 'childhood-stressed' women. Conclusions Higher current DQ, particularly as aligned with chronic disease prevention guidelines, predicts lower depression risk in women with low childhood adversity. DQ did not buffer depression risk in women with high childhood stress. Further research is warranted to examine persistent pathways of depression risk and diet's role within.

Objective:Household food insecurity is associated with CVD risk factors in low-income adults, but research on these associations among adolescents is inconsistent. This study investigates whether household and child food insecurity is associated with CVD risk factors in lower-income adolescents.Design:Cross-sectional. Multivariable linear regression assessed the association between household and child food security and CVD risk factors. Household and child food security was measured using the US Food Security Survey Module. The analyses were adjusted for adolescent’s age, sex, race/ethnicity, smoking status, physical activity and sedentary time, as well as household income and the head-of-household’s education and marital status.Setting:The USA.Participants:The sample was comprised of 2876 adolescents, aged 12–17 years, with household incomes at or below 300 % federal poverty line from the National Health and Nutrition Examination Survey cycles 2007–2016.Results:The weighted prevalence of household food insecurity in the analytic sample was 33·4 %, and the weighted prevalence of child food insecurity was 17·4 %. After multivariable adjustment, there were no significant associations between household and child food insecurity and BMI-for-age Z-score, systolic and diastolic blood pressure, HDL-cholesterol, total cholesterol, fasting TAG, fasting LDL-cholesterol and fasting plasma glucose.Conclusions:Despite observed associations in adults, household food insecurity was not associated with CVD risk factors in a national sample of lower-income adolescents. Child food insecurity was also not associated with CVD risk factors. More research should be conducted to confirm these associations.

Background College students experience a disproportionately high prevalence of both food insecurity and eating disorders. Food insecurity is associated with stress, irregular eating patterns, weight change, depression, and body dissatisfaction, making it a possible risk factor for the onset of eating disorders. However, the association between food insecurity and eating disorders among college students is not well understood. Objective This study explored the relation between food insecurity and screening positive for an eating disorder among students attending a large, public Midwestern university. Design Cross-sectional data were collected using an online survey administered from March through June 2018. Participants/setting Participants were recruited from a random sample of 2,000 students, with oversampling from the following groups: racial/ethnic minorities, first-generation students, and students from lower-income households. Of those sampled, 851 students (43%) responded. The final analytic sample comprised 804 students after excluding those with missing data. Main outcome measure The validated 5-item Sick, Control, One stone, Fat, Food (SCOFF) questionnaire was used to screen for the presence of an eating disorder. Statistical analyses performed Poisson regression was used to model prevalence ratios for positive SCOFF screens (≥2 affirmative responses) by levels of food security (ie, high, marginal, low, or very low). Models were adjusted for sex, age, race/ethnicity, degree type, financial aid, and first-generation student status. Results Compared to students with high food security, a higher prevalence of positive SCOFF screens was found among students with marginal food security (prevalence ratio [PR], 1.83, 95% CI 1.26 to 2.65; P = 0.001), low food security (PR 1.72, 95% CI 1.16 to 2.54; P = 0.007), and very low food security (PR 2.83, 95% CI 2.01 to 3.97; P Conclusions Students with food insecurity at any level were more likely to screen positive for an eating disorder via the SCOFF questionnaire. Prospective studies are needed to determine whether food insecurity is a risk factor for the onset of eating disorders among college students.

BackgroundHealth-related warning labels may reduce the intake of sugar-sweetened beverages (SSBs), but the effectiveness of such labels in real-world settings is not well established.ObjectivesWe investigated the influence of warning labels on SSB intake among college students at a large public Midwestern university.MethodsWe conducted a quasi-experimental intervention study among 840 undergraduate students recruited from 3 dining halls on 1 university campus. One dining hall was selected as the intervention (I) site, whereas the other dining halls served as control (C) sites. In January 2019, warning labels were posted on SSB dispensers at the I site. All students reported their beverage intake using a modified beverage frequency questionnaire 2 mo before and 2 mo after the warning label implementation. Generalized linear models examined the influence of the warning labels on SSB consumption at the I site compared with the C sites, adjusting for students' sociodemographic characteristics.ResultsIn the sample, 68% were aged 17-18 y old at baseline, and 51% identified as female. From baseline to follow-up, there was a 19% decrease in SSB intake at the I site, compared with a 5% decrease at the C sites (P=0.049 comparing I with C). This difference was driven by significant decreases in the intakes of fruit-flavored drinks, sweetened teas, and flavored milk at the I site compared with the C sites. Although not an SSB, 100% fruit juce consumption decreased 21% at the I site, compared with a 1% increase at the C sites (P=0.01 comparing I with C). No significant differences were observed in the intakes of soda, energy drinks, sweetened coffees, and nonsugary drinks at the I site compared with the C sites.ConclusionsWarning labels were effective in reducing SSB intake among college students, particularly for fruit-flavored drinks, sweetened teas, and flavored milk.This trial was registered at clinicaltrials.gov as NCT04435145.

During adolescence, diet quality reaches its lowest point compared to other childhood life stages. Acculturation is associated with decreased diet quality among many groups of United States (US) immigrant adults, but research is limited among adolescents.To investigate the associations between birthplace and length of time living in the US, two proxy measures of acculturation, with diet quality among adolescents (12-19 years old).Data were from the National Health and Nutrition Examination Survey (2007-2018), which included two 24-hour dietary recalls (n = 6,113) to estimate Healthy Eating Index-2015 (HEI-2015) total scores and component scores. Multivariate linear regression and generalized linear models were performed to compare HEI-2015 total scores and component scores between US-born adolescents (n = 5342) and foreign-born adolescents with5 years (n = 244), 5 -10 years (n = 201), and ≥10 years (n = 290) of US residency.Foreign-born adolescents with5 years (53.3±1.2), 5 -10 years (51.4±1.5), and ≥10 years of US residency (49.9±0.8) had higher HEI-2015 total scores than US-born adolescents (47.0±0.3, p0.0001) and higher total vegetables, seafood and plant proteins, and added sugars scores (Ps≤0.0001). Foreign-born adolescents with more years of US residency had higher total fruits, whole fruits, and saturated fats scores than those with fewer years of US residency. Sensitivity analysis revealed this pattern held for Mexican American/other Hispanic adolescents.Being born outside the US and living in the US for less time (among foreign-born adolescents) is associated with higher diet quality. Culturally informed health promotion programs may help to reduce diet-related disparities related to acculturation among adolescents.

Objective:To explore explicit beliefs about the controllability of obesity and the internalisation of negative weight-related stereotypes among public health trainees.Design:Cross-sectional online survey assessing explicit beliefs about the controllability of obesity using the Beliefs About Obese Persons Scale (BAOP) and internalisation of weight bias using the Modified Weight Bias Internalization Scale (WBIS-M). Bivariate associations between BAOP and WBIS-M scores and demographic characteristics were examined using t tests or ANOVA with post hoc Tukey’s tests.Setting:School of Public Health at a large, Midwestern University.Participants:Public health students (n 322).Results:Relative to students who identified as male, those who identified as female had a stronger belief that obesity is not within the control of the individual (P = 0·03), yet had more internalisation of weight bias (P < 0·01). Greater weight bias internalisation was also seen among students who perceived themselves to be of a higher weight status (P < 0·001) and those who were at risk for food insecurity (P < 0·01).Conclusions:Public health trainees may be more attuned to the complexities of weight relative to trainees in other health-related fields, but are still susceptible to internalisation of negative weight-related stereotypes.

Food insecurity increases the risks of diet-related chronic disease and mental health outcomes in low-income adults; however, the pathways underlying these associations have not been clearly identified. Chronic, psychological distress may represent an important pathway between food insecurity and health.To identify types of psychological distress, experiential descriptions, and the array of emotional responses and coping strategies specific to food insecurity among parents with children DESIGN: A phenomenological qualitative study using one-on-one, in-depth interviews.Forty-eight adults (parents) were recruited from the San Francisco Bay Area in 2016-17. Eligibility criteria included any experience of household food insecurity over the past 12 months, having a child aged 7 to 14 years, and both parent and child with the ability to speak English fluently.Data were analyzed using the constant comparative method to reveal emergent themes across multiple interviews.Parents discussed six themes related to the psychological distress of food insecurity: stress from the logistical and financial balancing act of feeding one's family, frustration and lack of choice associated with the high costs of healthy foods, stigma of using community resources, shame of not being able to provide for one's family, sadness about their cyclical and chronic food situation, and guilt over their inability to adequately provide for their children. Coping responses included negative responses, such as sleeping and drinking to avoid thinking about food insecurity, and positive responses of relying on their friends and family for support, staying hopeful, and spending time with their children.The commonality of emotional responses stemming from the experience of food insecurity can increase the risk for clinical anxiety and depression. Future development of interventions and policies to alleviate food insecurity must include social support and adequate safety systems.

Food insecurity is a critical public health problem in the United States that has been associated with poor diet quality. Cooking dinner more frequently is associated with better diet quality.This study aimed to examine how food insecurity and dinner cooking frequency are associated with diet quality during the initial months of the coronavirus disease 2019 pandemic.This cross-sectional study analyzed data from a national web-based survey (June 23 to July 1, 2020).Participants were 1,739 low-income (250% of the federal poverty level) adults in the United States.The outcome was diet quality, measured by the Prime Diet Quality Score (PDQS-30D). The PDQS-30D is a food frequency questionnaire-based, 22-component diet quality index.Food security status (high, marginal, low, or very low) and frequency of cooking dinner (7, 5 to 6, 3 to 4, or 0 to 2 times/week) were evaluated in relation to PDQS-30D scores (possible range = zero to 126) in age- and sex and gender-, and fully adjusted linear regression models. Postestimation margins were used to predict mean PDQS-30D score by food security status and dinner cooking frequency. The interaction between food security status and frequency of cooking dinner was also tested.Overall, the mean PDQS-30D score was 51.9 ± 11 points (possible range = zero to 126). The prevalence of food insecurity (low/very low) was 43%, 37% of the sample cooked 7 times/week and 15% cooked 0 to 2 times/week. Lower food security and less frequent cooking dinner were both associated with lower diet quality. Very low food security was associated with a 3.2-point lower PDQS-30D score (95% CI -4.6 to -1.8) compared with those with high food security. Cooking dinner 0 to 2 times/week was associated with a 4.4-point lower PDQS-30D score (95% CI -6.0 to -2.8) compared with cooking 7 times/week. The relationship between food insecurity and diet quality did not differ based on cooking dinner frequency.During the initial months of the coronavirus disease 2019 pandemic food insecurity and less frequently cooking dinner at home were both associated with lower diet quality among low-income Americans. More research is needed to identify and address barriers to low-income households' ability to access, afford and prepare enough nutritious food for a healthy diet.

Objective: To examine the effect of food insecurity during college on graduation and degree attainment. Design: Secondary analysis of longitudinal panel data. We measured food insecurity concurrent with college enrollment using the 18-question USDA Household Food Security Survey Module. Educational attainment was measured in 2015-2017 via two questions about college completion and highest degree attained. Logistic and multinomial-logit models adjusted for sociodemographic characteristics were estimated. Setting: United States (US) Participants: A nationally representative, balanced panel of 1,574 college students in the US in 1999-2003 with follow-up through 2015-2017 from the Panel Study of Income Dynamics. Results: In 1999-2003, 14.5% of college students were food insecure and were more likely to be older, non-White, and first-generation students. In adjusted models, food insecurity was associated with lower odds of college graduation (OR 0.57, 95% CI: 0.37, 0.88, p=0.01) and lower likelihood of obtaining a Bachelor’s degree (RRR 0.57 95% CI: 0.35, 0.92, p=0.02) or graduate/professional degree (RRR 0.39, 95% CI: 0.17, 0.86, p=0.022). These associations were more pronounced among first-generation students. 47.2% of first-generation students who experienced food insecurity graduated from college; food insecure first-generation students were less likely to graduate compared to first-generation students who were food secure (47.2% vs. 59.3%, p=0.020) and non-first-generation students who were food insecure (47.2% vs. 65.2%, p=0.037). Conclusions: Food insecurity during college is a barrier to graduation and higher degree attainment, particularly for first-generation students. Existing policies and programs that help mitigate food insecurity should be expanded and more accessible to the college student population.

AIMS: The purpose of this study was to examine whether pandemic exposure impacted unmet social and diabetes needs, self-care behaviors, and diabetes outcomes in a sample with diabetes and poor glycemic control. METHODS: This was a cross-sectional analysis of participants with diabetes and poor glycemic control in an ongoing trial (n = 353). We compared the prevalence of unmet needs, self-care behaviors, and diabetes outcomes in successive cohorts of enrollees surveyed pre-pandemic (prior to March 11, 2020, n = 182), in the early stages of the pandemic (May-September, 2020, n = 75), and later (September 2020-January 2021, n = 96) stratified by income and gender. Adjusted multivariable regression models were used to examine trends. RESULTS: More participants with low income reported food insecurity (70% vs. 83%, p < 0.05) and needs related to access to blood glucose supplies (19% vs. 67%, p < 0.05) during the pandemic compared to pre-pandemic levels. In adjusted models among people with low incomes, the odds of housing insecurity increased among participants during the early pandemic months compared with participants pre-pandemic (OR 20.2 [95% CI 2.8-145.2], p < 0.01). A1c levels were better among participants later in the pandemic than those pre-pandemic (s = -1.1 [95% CI -1.8 to -0.4], p < 0.01), but systolic blood pressure control was substantially worse (s = 11.5 [95% CI 4.2-18.8, p < 0.001). CONCLUSION: Adults with low-incomes and diabetes were most impacted by the pandemic. A1c may not fully capture challenges that people with diabetes are facing to manage their condition; systolic blood pressures may have worsened and problems with self-care may forebode longer-term challenges in diabetes control.

Objective In youth, a preoccupation with weight and the desire to be thinner, or drive for thinness, might persist into adulthood and predict reward-based compulsive eating and greater weight status. Methods A total of 623 women were enrolled from a prospective cohort study starting at 10 years old and assessed up to 20 years later. Drive for thinness was measured five times during adolescence. In adulthood (mean age = 39.5), drive for thinness, reward-based eating drive, and BMI were measured. Results Structural equation modeling found cumulative adolescent drive for thinness predicted higher scores for both adult drive for thinness and reward-based eating drive. Youth drive for thinness was not directly associated with adult BMI but rather indirectly through adult drive for thinness. Reward-based eating drive was not associated with adult BMI. Conclusions Drive for thinness during the critical developmental years may exert long-term effects on adulthood eating behaviors tied to greater weight gain, potentially reflecting an important early target of intervention.

Background Shorter leukocyte telomere length (LTL) is associated with increased risk of a number of metabolic diseases including insulin resistance and the development of type 2 diabetes mellitus. Shorter LTL is also associated with stress reactivity suggestive of a possible role for LTL to predict response to behavioral interventions. However, few studies have evaluated how interventions, such as weight loss or dietary changes, are associated with LTL changes or whether LTL can predict behavioral responses to interventions. Objectives We evaluated metabolic changes in relation to LTL changes and LTL at baseline in a cohort of at-risk adults in response to a 10-mo workplace-based sugar-sweetened beverage (SSB) intervention. Methods At baseline, metabolic health and LTL measurements were assessed through standard blood draws on 212 participants. Multivariable linear regression models were used to assess changes in anthropometrics, SSB consumption, and 13 blood-based metabolic risk factors, in relation to LTL at baseline and changes in LTL. Results Longer LTL at baseline was associated with decreases in SSB consumption over the 6-mo follow-up period (B = −29.67; P = 0.04). Slower LTL attrition rates were associated with decreases in waist circumference (B = −0.27; P = 0.03), HDL cholesterol (B = −0.20; P = 0.05), and apoA1 (B = −0.09; P = 0.01). Conclusions Longer LTL at baseline predicted a favorable overall response to a behavioral intervention: decreases in SSB consumption. Abdominal adiposity losses paralleled slower declines in LTL suggestive of overall health benefits, but we found differences in the relations between metabolic changes and LTL at baseline compared with LTL attrition rates. Longer LTL may be a proxy marker of a positive behavioral response. This trial was registered at clinicaltrials.gov as NCT02585336., Longer leukocyte telomere length at baseline may be a predictor of positive behavioral response to a sugar-sweetened beverage reduction intervention in adults.

Objective:Using an adaption of the Photovoice method, this study explored how food insecurity affected parents’ ability to provide food for their family, their strategies for managing household food insecurity and the impact of food insecurity on their well-being.Design:Parents submitted photos around their families’ experiences with food insecurity. Afterwards, they completed in-depth, semi-structured interviews about their photos. The interviews were transcribed and analysed for thematic content using the constant comparative method.Setting:San Francisco Bay Area, California, USA.Participants:Seventeen parents (fourteen mothers and three fathers) were recruited from a broader qualitative study on understanding the experiences of food insecurity in low-income families.Results:Four themes were identified from the parents’ photos and interviews. First, parents described multiple aspects of their food environment that promoted unhealthy eating behaviours. Second, parents shared strategies they employed to acquire food with limited resources. Third, parents expressed feelings of shame, guilt and distress resulting from their experience of food insecurity. And finally, parents described treating their children to special foods to cultivate a sense of normalcy.Conclusions:Parents highlighted the external contributors and internal struggles of their experiences of food insecurity. Additional research to understand the experiences of the food-insecure families may help to improve nutrition interventions targeting this structurally vulnerable population.

Background Food insecurity is believed to influence the quality and quantity of foods consumed; however, studies examining food insecurity and diet quality have been inconclusive and few studies have explored variability in these associations by sex and race/ethnicity. Objective This study examined associations between food insecurity and diet quality, and variations by sex and race/ethnicity. Design Cross-sectional analysis of data from the 2011-2014 National Health and Nutrition Examination Surveys. Participants The study population was composed of 4,393 adults (aged 20 to 65 years) with family incomes ≤300% of the federal poverty level with complete data on household food security and dietary intake via two 24-hour dietary recalls. Main outcome measures Diet quality was assessed using the Healthy Eating Index-2015. Statistical analyses performed Associations between food insecurity and Healthy Eating Index-2015 total and component scores were examined using linear regression models and generalized linear models. Models adjusted for sociodemographic and health covariates. Results Compared with food-secure adults, food-insecure adults reported a 2.22-unit lower Healthy Eating Index-2015 score (95% CI –3.35 to –1.08). This association was most pronounced among non-Hispanic whites and adults of Asian or other races/ethnicities. There were no associations among non-Hispanic black or Hispanic adults, and no differences by sex. Among non-Hispanic whites, food insecurity was associated with lower scores for total protein foods, seafood and plant proteins, and added sugar. Among Asians, food insecurity was associated with lower scores for whole fruit. Conclusions Food insecurity was associated with lower diet quality primarily among non-Hispanic whites; Asians; and other adults, a group composed of American Indian or Alaska Natives, Native Hawaiian or Other Pacific Islanders, and multiracial adults. Further research is needed to better understand the nature of this association among understudied racial/ethnic groups.

Background Food insecurity is a growing issue of concern on college campuses. While many studies have focused on predictors of food insecurity, fewer studies have examined how food insecurity affects diet and diet-related outcomes among college students. Objective The objective of this study was to examine differences in dietary intake, food and cooking agency, and body mass index (calculated as kg/m2) by food security status in a sample of college students at a large, public midwestern university. Design We conducted a cross-sectional online survey administered from March to June 2018. Participants Students were recruited from a random sample (n=2,000) provided by the university, which included an oversample of minority racial/ethnic students from lower-income households and first-generation students. The response rate was 43% (n=851). After excluding students with missing data, the final sample was 754 enrolled students. Main outcome measures Food security status was measured using the US Adult Food Security Survey Module. Dietary intake was assessed using the National Cancer Institute dietary screener questionnaire. Cooking and food agency was measured using the Cooking and Food Provisioning Action Scale, a new validated questionnaire. Body mass index was calculated from self-reported height and weight. Statistical analysis performed Differences between food security categories and diet-related outcomes were examined using generalized linear models. Models adjusted for sociodemographic covariates, such as student’s age, sex, race/ethnicity, and receipt of financial aid. Results Compared to students with high food security, low food security was associated with lower intake of fruits, and very low food security was associated with higher intakes of total added sugar and added sugar from sugar-sweetened beverages. Marginal and very low food security were positively associated with body mass index. Marginal, low, and very low food security were inversely associated with cooking and food agency. Conclusions Students with food insecurity experience diet-related challenges that could translate into health disparities over time. More research is needed to understand the longitudinal effects of food insecurity on student health and well being.

BACKGROUND: Food insecurity, a social and economic condition of inadequate food resources, is known to affect cognitive development in children. However, research is sparse among adult populations, particularly older adults who may be more susceptible to accelerated cognitive decline. OBJECTIVE: The aim of this study was to examine the associations between food insecurity and cognitive functioning among older adults. METHODS: Data came from 1823 older adults (≥60 y) with incomes ≤300% of the federal poverty level (FPL) from the 2011–2014 NHANES. Food security was measured using the 10-item Adult Food Security Survey Module. Cognitive function was measured using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word learning subtest and delayed word recall, the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST). The cognitive assessments were then standardized and an overall cognitive function z score was created by averaging across all cognitive assessments. Associations with food insecurity were examined using multivariate linear regression models, adjusting for sociodemographic and health characteristics. RESULTS: In the analytic population, the prevalence of food insecurity was 23.7%. Across all cognitive assessments, the mean scores among food-insecure adults was significantly lower than the mean scores among food-secure adults. After adjusting for sociodemographic and health characteristics, food insecurity was associated with lower scores on the CERAD word learning subtest (β = −0.14, 95% CI: −0.26, −0.01), the AFT (β = −0.13, 95% CI: −0.25, −0.002), and the DSST (β = −0.24, 95% CI: −0.33, −0.15). Food insecurity was also associated with a lower score on the overall cognitive function z score (β = −0.15, 95% CI: −0.26, −0.05). CONCLUSIONS: In this national sample of 1823 adults aged ≥60 y, food insecurity was inversely associated with cognitive function, which may translate into higher risk of cognitive impairment over time.

The COVID-19 pandemic caused widespread non-essential business closures in the U.S., which may have disproportionately impacted food consumption in lower-income communities, in part due to reduced access to healthy and affordable foods, as well as occupations that may have required working outside the home. The aims of this study were to examine restaurant dining behaviors (including drive-through, takeout, and delivery) at fast-food and non-fast-food (i.e., fast casual and full-service ['other']) restaurants and the impact on diet quality among racially/ethnically diverse low-income adults during the early months of the pandemic. Participants completed an online survey using CloudResearch regarding restaurant dining behaviors in the past week (during June 2020) and during a typical week prior to the pandemic. Diet quality was measured using the Prime Diet Quality Score (PDQS). Surveys from 1,756 low-income adults (incomes

The Supplemental Nutrition Assistance Program (SNAP) is critical to alleviating food insecurity, but low diet quality among program participants is a concern. Nutrition-related interventions have focused on SNAP-authorized food retailers, but the perspectives of small food store owners and managers have not been represented in national policy discussions. This study aimed to explore the opinions of store owners/managers of SNAP-authorized small food stores about their overall perceptions of the program and the stricter stocking standards previously proposed in 2016. We conducted in-depth, semi-structured interviews with 33 small food store owners and managers in San Francisco and Oakland, California in 2016. Interviews were analyzed for thematic content using the general inductive approach. Four themes emerged from owners/managers’ discussion of their overall perceptions of SNAP: the beneficial impact of SNAP on their business, how SNAP enables them to connect with the broader community, the importance of SNAP in preventing hunger, and the nutrition-related struggles that SNAP participants face. Store owners/managers had a generally favorable response towards the proposed stricter stocking standards. Additional themes discussed pertained to the concern about whether stocking changes would lead SNAP participants to purchase more healthful food and some logistical challenges related to sourcing and storing perishable foods.

Allostatic load (AL), the concept of cumulative biological risk from chronic stressful exposures, may provide a framework with which to examine the links between diet, physiological stress, and disease.This study examined the associations between diet quality and AL.This cross-sectional study was conducted using the 2015 through 2018 cycles of the National Health and Nutrition Examination Survey. Dietary intake was assessed using two 24-hour diet recalls. Diet quality was measured using the Healthy Eating Index 2015. AL was measured by a composite score of nine biochemical markers, with three or more dysregulated values signaling elevated AL. All markers were collected during a physical examination.This study was conducted in a nationally representative population of 5,343 US adults aged 19 years or older who had no prior diagnosis of diabetes (except gestational diabetes), cancer (except skin cancer), or cardiovascular disease; were not pregnant; and had complete dietary intake and AL biomarker data.The outcome was odds of elevated AL.Accounting for the complex survey design of the National Health and Nutrition Examination Survey, multivariable logistic regression was used to examine the associations between Healthy Eating Index 2015 score and elevated AL, adjusting for sociodemographic variables.A significant inverse association between AL and diet quality was observed among adults aged 31 years and older but not among those aged 19 to 30 years. Among adults aged 31 years and older, those in higher quintiles of Healthy Eating Index 2015 score had significantly lower odds of elevated AL compared with the lowest quintile (P for trend0.05).These results suggest that, in adults older than age 30 years, consuming a more healthful diet is inversely associated with AL.

Objectives:To assess the association between perceived stress and adiposity among Chinese adults.Design:Cross-sectional study. Perceived stress was assessed using the 14-item perceived stress scale. Associations between quintiles of perceived stress and BMI and waist circumference were assessed using linear regression models and multinomial regression models. Estimates were adjusted for sociodemographic characteristics.Setting:2015 China Health and Nutrition Survey: 12 provinces covering a variety of geographic, economic development and health indicator situations.Participants:A total of 8385 adults of both sexes, aged 18–99 years, were included.Results:Overall, the mean perceived stress score was 22·7 (6·2), mean BMI was 24·3 (3·6) kg/m2 and prevalence of obesity (BMI ≥ 30 kg/m2) was 6·0 %. There were inverse associations between perceived stress quintiles with continuous BMI (P < 0·001), BMI categories (P = 0·015) and waist circumference (P = 0·047). Compared to adults in the lowest quintile of perceived stress, adults in the highest quintile of perceived stress had 0·44 kg/m2 lower mean BMI (95 % CI: −0·67, −0·21), 0·72 times the prevalence of obesity (95 % CI: 0·55, 0·94) and 0·73 times the prevalence of abdominal obesity (95 % CI: 0·61, 0·88). Results were similar when using Chinese-specific cut-points.Conclusion:Our results showed inverse associations between perceived stress quintiles and adiposity among Chinese adults. Future studies should aim to better understand the directionality of the observed associations and the potential biological and behavioural mechanisms underlying these associations in the Chinese population.

Purpose of Review This review examines the current evidence about the ways in which food insecurity relates to obesity in children and adolescents, examining diet and diet-related behaviors, and taking into consideration the role of stress. Recent Findings While living with food insecurity impacts stress and diet-related behaviors in children and adolescents, it is not clear whether food insecurity is associated with obesity above and beyond the influence of poverty. However, strategies to mitigate food insecurity and obesity are inherently connected, and recent examples from clinical practice (e.g., screening for food insecurity among patients) and advocacy (e.g., policy considerations regarding federal food programs such as the Supplemental Nutrition Assistance Program, or SNAP) are discussed. Summary Food insecurity and obesity coexist in low-income children and adolescents in the USA. The COVID-19 pandemic exerts disproportionate burden on low-income children and families, magnifying their vulnerability to both food insecurity and pediatric obesity.

BACKGROUND: Food insecurity, a state of not being able to consistently access nutritious food due to financial constraints, has been associated with poor dietary intake among college students. The extent to which campus food resources contribute to this association is unknown. OBJECTIVES: This study examined the association between food insecurity and dietary intake in a sample of undergraduate students with unlimited meal plans and dining hall access at a large, public Midwestern university. DESIGN: The study design is cross-sectional. The data used are baseline data from part of a broader sugar-sweetened beverage intervention study that were collected using a Qualtrics survey prior to the intervention. PARTICIPANTS/SETTING: The sample consisted of 1,033 undergraduate students recruited from three dining halls. The data were collected in November 2018. MAIN OUTCOME MEASURES: Food security was assessed using the 6-item Short Form Food Security Survey Module. Dietary intake was assessed using the National Cancer Institute 26-item Dietary Screener Questionnaire and the Beverage Intake Questionnaire-15. STATISTICAL ANALYSES PERFORMED: Generalized linear regression models were used to examine differences in dietary intake by students’ food security status, adjusting for students’ sociodemographic characteristics. RESULTS: In the sample, 14% of students were food-insecure. After adjusting for sociodemographic variables, food-insecure students reported 9% lower intake of fruits (P=0.02), 9% lower intake of vegetables (P

The COVID-19 pandemic has dramatically increased food insecurity in the United States (US). The objective of this study was to understand the early effects of the COVID-19 pandemic among low-income adults in the US as social distancing measures began to be implemented. On 19&ndash, 24 March 2020 we fielded a national, web-based survey (53% response rate) among adults with &lt, 250% of the federal poverty line in the US (N = 1478). Measures included household food security status and COVID-19-related basic needs challenges. Overall, 36% of low-income adults in the US were food secure, 20% had marginal food security, and 44% were food insecure. Less than one in five (18.8%) of adults with very low food security reported being able to comply with public health recommendations to purchase two weeks of food at a time. For every basic needs challenge, food-insecure adults were significantly more likely to report facing that challenge, with a clear gradient effect based on severity of food security. The short-term effects of the COVID-19 pandemic are magnifying existing disparities and disproportionately affecting low-income, food-insecure households that already struggle to meet basic needs. A robust, comprehensive policy response is needed to mitigate food insecurity as the pandemic progresses.

OBJECTIVES: Food insecurity, a state of not being able to consistently access nutritious food, is an issue that 43% of students on college campuses experience. This study examines the associations between food insecurity and dietary intake in a sample of undergraduate students at a large, public Midwestern university. METHODS: A Qualtrics survey was completed by 1033 students, recruited from three dining halls as part of a different sugar-sweetened beverage intervention study. Baseline data, collected prior to the intervention, were used in the present study. Food security was assessed using the 6-item Short Form Food Security Survey Module and dietary intake was assessed using the National Cancer Institute 26-item Dietary Screener Questionnaire and the Beverage Intake Questionnaire-15. Generalized linear regression models were used to examine differences in dietary intake by student's food security status. RESULTS: After adjusting for sociodemographic variables, food-insecure students reported 9% lower intake of fruits, 9% lower intake of vegetables, 10% higher intake of dairy, 6% higher intake of total added sugars, 10% higher intake of added sugars from sugar-sweetened beverages, 4% higher intake of calcium, and 4% lower intake of fiber, compared to food-secure students. With respect to beverage intake, food-insecure students had 55% higher intake of fruit drinks, 148% higher intake of energy drinks, 129% higher intake of sweetened teas, 46% higher intake of flavored milk, 54% higher intake of total sugar-sweetened beverages, and 66% higher intake of diet soda. CONCLUSIONS: Despite having similar access to university dining halls, there were significant differences in the diets of college students by food security status, providing more reason to increase food insecurity awareness among college students and contribute to initiatives to alleviate food insecurity, such as on-campus food pantry programs. FUNDING SOURCES: This study was supported by a grant from Poverty Solutions at the University of Michigan.

Household food insecurity has been associated with adverse health outcomes, however, the mechanisms underlying these associations are not well-defined. Using data from 5005 adults from the 2007&ndash, 2010 National Health and Nutrition Examination Surveys (NHANES), we examined associations between household food insecurity and cumulative biological risk, a measure of the body&rsquo, s physiological response to chronic stress. Household food security was assessed using the 18-item Household Food Security Survey Module. Marginal food security refers to 1&ndash, 2 positive responses, and food insecurity refers to &ge, 3 positive responses. The cumulative biological risk scores were calculated based on the distributions of ten biomarkers from the cardiovascular, metabolic, and immune systems. Elevated biological risk was defined as a risk score of &ge, 3. Multivariable regression models were used to examine associations between food security and cumulative biological risk scores, adjusting for sociodemographic characteristics. After multivariable adjustment, food insecurity was associated with a 0.14-unit higher cumulative biological risk score (95% CI 0.05&ndash, 0.22, p-trend = 0.003) and higher odds of elevated biological risk (OR 1.20, 95% CI 1.05&ndash, 1.37, p-trend = 0.003). These associations differed by gender. Among women, food insecurity was associated with 0.30-unit higher cumulative biological risk score (95% CI 0.14&ndash, 0.45, p-trend = 0.0004) and higher odds of elevated biological risk (OR 1.61, 95% CI 1.29&ndash, 2.00, p-trend &lt, 0.0001). These associations were not observed in men. Women experiencing food insecurity demonstrated elevated levels of biological risk. These findings support the hypothesis that food insecurity may be associated with women&rsquo, s chronic health outcomes through the pathway of chronic stress. Further research is needed to understand why these associations were not observed in men.

Objective:To examine the association between cooking frequency and Healthy Eating Index (HEI)-2015, overall and by income, among US adults.Design:Cross-sectional analysis using multivariable linear regression models to examine the association between cooking frequency and total HEI-2015 score adjusted for sociodemographic variables, overall and stratified by income.Setting:Nationally representative survey data from the USA.Participants:Adults aged ≥20 years (with 2 d of 24 h dietary recall data) obtained from the 2007 to 2010 National Health and Nutrition Examination Survey (n 8668).Results:Compared with cooking dinner 0–2 times/week, greater cooking frequency was associated with higher HEI-2015 score overall (≥7 times/week: +3·57 points, P < 0·001), among lower-income adults (≥7 times/week: +2·55 points, P = 0·001) and among higher-income adults (≥7 times/week: +5·07 points, P < 0·001). Overall, total HEI-2015 score was higher among adults living in households where dinner was cooked ≥7 times/week (54·54 points) compared with adults living in households where dinner was cooked 0–2 times/week (50·57 points). In households in which dinner was cooked ≥7 times/week, total HEI-2015 score differed significantly based on income status (lower-income: 52·51 points; higher-income: 57·35 points; P = 0·003). Cooking frequency was associated with significant differences in HEI-2015 component scores, but associations varied by income.Conclusions:More frequent cooking at home is associated with better diet quality overall and among lower- and higher-income adults, although the association between cooking and better diet quality is stronger among high-income adults. Strategies are needed to help lower-income Americans consume a healthy diet regardless of how frequently they cook at home.

Accelerated telomere shortening has been associated with several age-related diseases and/or decreased lifespan in humans. The Mediterranean diet (MedDiet) is considered to be 1 of the most recognized diets for disease prevention and healthy aging, partially due to its demonstrated anti-inflammatory and antioxidative properties which may impact on telomere length (TL). The aim of this meta-analysis was to determine the associations between MedDiet adherence and TL maintenance. MEDLINE-PubMed and Cochrane databases were searched up to December 2018 for studies evaluating the association between MedDiet adherence and TL in blood cells. Two reviewers, working independently, screened all titles and abstracts to identify studies that met the inclusion criteria [cross-sectional, case-control, and prospective cohort studies and randomized clinical trials (RCTs) published in English and excluded nonoriginal articles]. Data were pooled by the generic inverse variance method using the random effects model and expressed as standardized mean difference (SMD). Heterogeneity was identified using the Cochran Q test and quantified by the I(2) statistic. A total of 8 original cross-sectional studies were included for the quantitative meta-analysis, comprising a total of 13,733 participants from 5 countries. A positive association between adherence to the MedDiet and TL was observed in all meta-analyses, with the exception of those conducted only in men: SMD (95% CI) of 0.130 (0.029; 0.231) for all subjects, 0.078 (0.005; 0.152) for women, and 0.095 (–0.005; 0.195) for men. Only 1 prospective cohort study and 1 RCT were identified, therefore, we could not undertake a meta-analysis for these study designs. The present meta-analysis of cross-sectional studies demonstrates that higher MedDiet adherence is associated with longer TL. At the same time, larger and high-quality prospective studies and clinical trials are warranted to confirm this association.

Background A carbohydrate-restricted (CR) diet can improve glycemic control in people with type 2 diabetes mellitus (T2DM). There are concerns, however, that the high dietary fat content of CR diets can increase low-density lipoprotein cholesterol (LDL-C), thus increasing cardiovascular disease (CVD) risk. Quantifying CVD risk associated with changes in LDL-C in the context of CR diets is complicated by the fact that LDL-C reflects heterogeneous lipids. For example, small LDL particle number (sLDL-P) is more closely associated with CVD risk than is total LDL-C, and CR diets tend to decrease the proportion of sLDL-C in LDL-C, which standard lipid measures do not indicate. Advanced lipoprotein assays, such as nuclear magnetic resonance (NMR) testing, can subfractionate lipoproteins by size and density and may better depict the effects of CR diets on CVD risk. Methods Adults (N = 58) with T2DM (n = 37 women; baseline HbA1c ≥ 6.5%) completed a 6-month group-based CR diet intervention. We obtained a standard lipid panel, advanced lipoprotein assays (NMR testing), and two 24-h diet recalls at baseline and post-intervention (6 months). Participants also completed home-based blood ketone testing (a biological index of dietary adherence) during the final five weeks of the intervention. Results From baseline to post-intervention, participants had increased mean HDL-C, decreased triglycerides and triglyceride/HDL ratio, decreased mean sLDL-P, and increased LDL size, which reflect reductions in CVD risk (ps

The aim of this study was to investigate the association between single-nucleotide polymorphisms (SNPs) in vitamin D metabolic pathway genes, serum 25-hydroxyvitamin D [25(OH)D] concentrations, and leukocyte telomere length (LTL) in Brazilian adults.The study population comprised 461 participants (33-79 y of age; 51% women) from the Pró-Saúde Study, a cohort of civil servants at a university campus in Rio de Janeiro, Brazil. LTL, genotypes of vitamin D-related SNPs (rs12785878, rs10741657, rs6013897, and rs2282679), and serum 25(OH)D concentrations were determined cross-sectionally. Differences in age- and sex-adjusted LTL means by categories of genotypes and 25(OH)D serum concentrations were evaluated. LTL associations with genotypes and 25(OH)D were investigated using multiple linear regression models adjusted for sociodemographic characteristics and markers of health behavior.Participants with CC genotype (rs2282679) had shorter age- and sex-adjusted mean LTL than those with AC and AA genotypes (mean ± SE: 0.51 ± 0.03, 0.58 ± 0.01 and 0.5 ± 0.01, respectively, P0.05). In adjusted analyses, the CC genotype (rs2282679) was inversely associated with LTL (β = -0.061; 95% confidence interval, -0.120 to -0.001). Other vitamin D-related SNPs and serum 25(OH)D concentrations were not associated with LTL.Genetic variations in the gene encoding vitamin D binding protein (GC - rs2282679) were associated with LTL, suggesting an influence of vitamin D status on telomere length that may start early in life.

Background Food insecurity, a condition of inadequate household food availability, affects 15.7% of US households with children. Food insecurity is generally believed to affect the quantity and quality of food consumed. However, an understudied but important aspect of the experience of food insecurity is psychological distress. Objective To critically explore the psychological distress associated with children’s food insecurity using children’s own reports of their experiences. Design In-depth qualitative interviews conducted with children to better understand the psychological distress associated with food insecurity. Participants/setting Sixty children (aged 7 to 14 years) were recruited from the San Francisco Bay Area. Children were eligible in the case that they spoke English fluently and their parent reported any experience of household food insecurity during the past year. Results Children discussed six themes related to the psychological distress associated with food insecurity: worrying about not having enough food, worrying about their parents’ well-being, anger and frustration about not having enough food, embarrassment about their family’s food situation, strain on the family’s dynamics due to food insecurity, and sadness over not having enough food. After describing their experiences, children described strategies they employed to tolerate or cope with food insecurity, including distracting from or using their imagination to cope with food insecurity, increasing tolerance of their family’s food situation, and appreciating their parents for providing food and resources. Conclusions Food insecurity contributes to children’s psychological distress. Given the known effects of chronic stress in childhood, the psychological distress of food insecurity may represent an important mechanism by which food insecurity adversely influences children’s growth and development and deserves investigation in future studies.

Insufficient sleep duration is a recognized determinant of cardiometabolic disease, with poor diet quality as a likely intermediate. Yet, inconsistencies in findings on sleep duration and diet quality among adult populations remain, particularly regarding a potential non-linear relationship. Thus, within a nationally representative survey of US adults (2011–2016 National Health and Nutrition Survey), we evaluated cross-sectional associations between sleep duration and diet quality. Self-reported typical sleep duration was categorized into four groups (≤5 h per night, 6 h, 7–8 h, and ≥9 h per night). Diet was assessed with two 24-h recalls (averaged), and diet quality was measured with the Healthy Eating Index-2015 (score range 0–100), which is comprised of 13 dietary components. Regression analyses that accounted for complex survey weights were used to compute multivariable-adjusted models of sleep duration categories and HEI-2015 overall scores, and individual HEI components. Within this nationally-representative sample of adults ≥18 years, 10% reported 5 or fewer hours of sleep, and 20% reported 6 h, while 12% obtained ≥9 h (long sleep duration). Compared to adults with 7–8 h of sleep, those with ≤5 h had 1.7 lower multivariable-adjusted HEI-2015 score (95% CI 0.6, 2.7), and those with ≥9 h had 1.2 lower adjusted HEI-2015 score (95% CI 0.2, 2.2). Upon examination of individual HEI-2015 components, short sleepers had lower consumption of healthier components (total fruits, whole fruits, total vegetables, greens and bean, whole grains, dairy, total protein, and seafood), while long sleepers had higher consumption of some unhealthier components (refined grains and added sugar) as well as some healthier components (dairy and total protein). In conclusion, within a nationally-representative US survey, a reverse U-shaped association was observed between sleep duration and dietary quality.

OBJECTIVES: Food insecurity increases the risks of numerous chronic disease and mental health outcomes in low-income adults; however, the mechanisms underlying these associations have not been clearly identified. Chronic, psychological stress may represent an important pathway between food insecurity and health. Using in-depth interviews, the objective of this qualitative study was to obtain a better understanding of psychological distress specific to food insecurity among adults. METHODS: We conducted one-on-one, semi-structured interviews with 48 parents recruited from the San Francisco Bay Area. Eligibility criteria included any experience of household food insecurity over the past 12 months, having a child in the family, and the ability to speak English fluently. An interview guide was developed by an interdisciplinary research team to specifically delve into the psychological experience of adult food insecurity. Interviews were audio-recorded, transcribed, and analyzed for thematic content using the constant comparative method. RESULTS: Parents discussed six themes related to the psychological distress of food insecurity: 1) anxiety about not having enough food to meet the needs of all family members, 2) frustration over the high costs of healthful foods (e.g., fruits and vegetables), 3) embarrassment about using community food assistance, 4) fear of running out of money for food and other necessities, 5) sadness about their cyclical and chronic food situation, and 6) guilt over the inability to adequately provide for their children. Strategies that parents used to cope with food insecurity included seeking help from family and friends, relying on their faith, distracting themselves from their current situation (e.g., sleeping, cleaning, drinking), and becoming increasingly tolerant of their food situation. CONCLUSIONS: Food insecurity is a source of psychological distress among parents. Psychological distress may represent a pathway by which food insecurity influences physical and mental health outcomes. FUNDING SOURCES: This study was supported by a grant from the Eunice Kennedy Shriver National Center for Child Health and Human Development.

To examine associations between psychological stress and dieting behavior along with the heterogeneity of this association by gender and race in a diverse sample of adolescents with overweight/obesity.One hundred and sixty-one adolescents between the ages of 13-19 years of age with overweight/obesity (65% female; 53% non-Hispanic black/47% non-Hispanic white; age: 16.7 ± 1.7 years) were recruited from Southeast MI and included in this analysis. Psychological stress was measured using the Perceived Stress Scale, and dieting behavior was assessed using the dieting subscale from the Eating Attitudes Test (EAT-26) questionnaire. Multivariable linear regression models were conducted to examine the association between psychological stress and dieting behavior by gender and race.Psychological stress was significantly associated with dieting (β = 0.18 ± 0.06; p 0.01), with greater stress associated with greater frequency of dieting behavior. This relationship remained significant (β = 0.15 ± 0.06; p = 0.016), even when controlling for covariates (age, body fat, gender, race, and pubertal development). There were no statistically significant differences in the association of psychological stress and disordered eating indices by gender or race/ethnicity (p's 0.05).Increased psychological stress is associated with increased dieting behavior among adolescents with overweight/obesity. These findings suggest that psychological stress equally affects dieting behavior among adolescents with overweight/obesity, regardless of gender and race. Future studies should seek to identify the unique sources of psychological stress that contribute to increased dieting behavior among adolescents with overweight/obesity.

Background The issue of food insecurity is one of growing concern among institutions of higher learning in the United States. In addition to studies on the prevalence and risk factors, research is needed to better understand the mechanisms by which food insecurity affects students' health and well-being. Objective To critically explore the experience of food insecurity among college students and its impact on psychosocial health and academic performance. Design In-depth qualitative interviews were conducted with college students to gain a better understanding of the mechanisms by which food insecurity affects their psychosocial health and academic performance. Participants/setting Twenty-five undergraduate students from a large public university in California who were recruited from a campus food pantry. Results Students discussed several themes related to the psychosocial effects of food insecurity: the stress of food insecurity interfering with daily life, a fear of disappointing family, resentment of students in more stable food and financial situations, an inability to develop meaningful social relationships, sadness from reflecting on food insecurity, feeling hopeless or undeserving of help, and frustration directed at the academic institution for not providing enough support. Students also discussed how food insecurity affected their academic performance through physical manifestations of hunger and the mental trade-off between focusing on food and focusing on academics. Conclusion These findings contribute to the understanding of what it means to experience food insecurity in higher education and can inform how universities support students’ basic needs.

Objective To examine whether short-term participation in the Supplemental Nutrition Assistance Program (SNAP) affects food security and dietary quality among low-income adults recruited from a Massachusetts-wide emergency food hotline. Methods A 3-month, longitudinal study was conducted among 107 adults recruited at the time of SNAP application assistance. Outcomes included household food security (10-item US Department of Agriculture Food Security Survey Module), dietary intake (eg, grains, fruit) and diet quality (modified Alternate Healthy Eating Index). Data were analyzed using paired t tests and multivariable linear regression. Results Supplemental Nutrition Assistance Program participation was not associated with improved household food security over 3 months (P = .25). Compared with non-participants, SNAP participants increased refined grain intake by 1.1 serving/d (P = .02), from baseline to follow-up. No associations were observed with other foods, nutrients, or dietary quality. Conclusion and Implications Policies that simultaneously improve household food security and dietary quality should be implemented to support the health of low-income Americans participating in this crucial program.

OBJECTIVES: Food insecurity is a critical concern for college students. Food insecurity is associated with stress, irregular eating patterns, weight change, and depression, making it a plausible risk factor for disordered eating in college students, who are already at high risk of eating disorders. We explored the relation between food insecurity and screening positive for a possible eating disorder among students attending a large, public Midwestern university. METHODS: Data were collected cross-sectionally via an online survey during the Winter 2018 semester. The analytic sample totaled 762 after excluding students with missing data for exposure or outcome. The 10-item U.S. Adult Food Security Survey Module was used to measure food security status, which was classified into four categories: food security, marginal food security, low food security, and very low food security. Participants were screened for the presence of a possible eating disorder using the 5-item SCOFF questionnaire, with a positive screen defined as ≥2 affirmative answers. We used Poisson regression to model the prevalence of SCOFF positive screens and item-level affirmative responses by food security categories, adjusting for age, sex, race/ethnicity, family income, and first-generation status. RESULTS: A higher prevalence of positive SCOFF screens was observed among students with marginal food security (PR 1.76, 95% CI 1.67, 1.86), low food security (PR 1.62, 95% CI 1.53, 1.72), and very low food security (PR 2.79, 95% CI 2.65, 2.94), after adjusting for demographic characteristics. Food insecurity was also positively related to prevalence of affirmative responses for four SCOFF items. CONCLUSIONS: This study shows that college students with food insecurity are more likely to screen positive for a possible eating disorder compared to food secure students. More research is needed to understand the complicated relationship between these two food-related constructs among college students.

ObjectiveTo determine public attitudes towards federal spending on nutrition assistance programmes and support for policies to improve the nutritional impact of the Supplemental Nutrition Assistance Program (SNAP).DesignParticipants answered survey questions by telephone assessing support for SNAP spending and proposed programme policy changes.SettingUSA.SubjectsSurvey of 3024 adults selected by random digit dialling conducted in April 2012, including 418 SNAP participants.ResultsA majority (77 %; 95 % CI 75, 79 %) of all respondents supported maintaining or increasing SNAP benefits, with higher support among Democrats (88 %; 95 % CI 86, 90 %) than Republicans (61 %; 95 % CI 58, 65 %). The public supported policies to improve the nutritional impact of SNAP. Eighty-two per cent (95 % CI 80, 84 %) of respondents supported providing additional benefits to programme participants that can only be used on healthful foods. Sixty-nine per cent (95 % CI 67, 71 %) of respondents supported removing SNAP benefits for sugary drinks. A majority of SNAP participants (54 %; 95 % CI 48, 60 %) supported removing SNAP benefits for sugary drinks. Of the 46 % (95 % CI 40, 52 %) of SNAP participants who initially opposed removing sugary drinks, 45 % (95 % CI 36, 54 %) supported removing SNAP benefits for sugary drinks if the policy also included additional benefits to purchase healthful foods.ConclusionsThe US public broadly supports increasing or maintaining spending on SNAP. The majority of respondents, including SNAP participants, supported policies to improve the nutritional impact of SNAP by restricting the purchase of sugary drinks and incentivizing purchase of healthful foods with SNAP benefits.

ObjectiveTo examine whether the cross-sectional association between food insecurity and overweight/obesity varied according to birthplace and length of residence in the USA among California women.DesignUsing cross-sectional, population-based data from the California Women’s Health Survey (CWHS) 2009–2012, we examined whether the association between food insecurity and overweight or obesity varied by birthplace–length of US residence.SettingCalifornia, USA.SubjectsWomen (n16 008) aged 18 years or older.ResultsAmong US-born women, very low food security (prevalence ratio (PR)=1·21; 95 % CI 1·11, 1·31) and low food security (PR=1·19; 95 % CI 1·10, 1·28) were significantly associated with higher prevalence of overweight/obesity, after controlling for age, marital status, race/ethnicity, poverty and education. Among immigrant women who lived in the USA for 10 years or longer, very low food security was significantly associated with higher prevalence of overweight/obesity, after controlling for covariates (PR=1·16; 95 % CI 1·07, 1·27). Among immigrant women who had lived in the USA for less than 10 years, low and very low food security were not significantly associated with overweight/obesity, after controlling for covariates.ConclusionsFood insecurity may be an important pathway through which weight may increase with longer US residence among immigrant women. Public health programmes and policies should focus on increasing food security for all women, including immigrant women, as one strategy to reduce the prevalence of overweight/obesity.

Leukocyte telomere length (LTL) has been inversely associated with sugar-sweetened beverage (SSB) consumption in cross-sectional studies, but no studies have examined whether dietary intake influences LTL over time. This study examined longitudinal associations between sugary foods and beverages and LTL. Participants were 65 overweight and obese pregnant women, aged 18-45 years, from a mindfulness intervention study conducted from early pregnancy (⩽16 weeks gestation) and followed through 9 months postpartum. During pregnancy and postpartum, dietary intake was measured with 24-h diet recalls, and LTL was assessed using quantitative PCR. Adjusting for sociodemographic and health characteristics, decreased SSB consumption from baseline to 9 months postpartum was associated with greater concurrent LTL lengthening (β=-0.102, 95% confidence interval (CI) -0.192, -0.013). No associations between sugary foods and LTL were found in either period. The finding that reduced SSB consumption is associated with increased LTL warrants investigation in large cohort studies.

Background: The Supplemental Nutrition Assistance Program (SNAP) is the largest federal nutrition assistance program. In recent years, SNAP participation rates increased during times of economic hardship. Objective: We examined whether household SNAP participation was associated with adiposity and metabolic risk factors in a representative sample of low-income US adults. Design: A cross-sectional analysis was performed with the use of data from the 2003–2006 National Health and Nutrition Examination Surveys. The study population was restricted to nonelderly adults whose household incomes fell to or

ObjectivePublic assistance programmes may increase risk of obesity among adults. The current study assessed whether participation in the Supplemental Nutrition Assistance Program (SNAP; formerly the Food Stamp Program), Supplemental Security Income (SSI) or California Work Opportunities and Responsibilities to Kids (CalWorks) was associated with obesity, independent of socio-economic status and food insecurity.DesignA cross-sectional analysis of the 2007 Adult California Health Interview Survey. Outcome measures included BMI and obesity. Distribution of BMI and prevalence of obesity were compared by participation in each programme, using weighted linear and binomial regression models in which BMI or obesity was the outcome, respectively, and programme participation was the predictor.SettingA population survey of various health measures.SubjectsNon-institutionalized adults (n 7741) whose household income was ≤130 % of the federal poverty level.ResultsThe prevalence of obesity was 27·4 %. After adjusting for sociodemographic characteristics, food insecurity and participation in other programmes, the prevalence of obesity was 30 % higher in SNAP participants (95 % CI 6 %, 59 %; P = 0·01) than in non-participants. This association was more pronounced among men than women. SSI participation was related to an adjusted 50 % higher prevalence of obesity (95 % CI 27 %, 77 %; P < 0·0001) compared with no participation. SNAP and SSI participants also reported higher soda consumption than non-participants of any programme. CalWorks participation was not associated with obesity after multivariable adjustment.ConclusionsParticipation in SNAP or SSI was associated with obesity independent of food insecurity or socio-economic status. The suggestion that these associations may be mediated by dietary quality warrants further investigation among low-income populations.

ObjectiveTo examine the opinions of stakeholders on strategies to improve dietary quality of Supplemental Nutrition Assistance Program (SNAP) participants.DesignParticipants answered a thirty-eight-item web-based survey assessing opinions and perceptions of SNAP and programme policy changes.SettingUSA.SubjectsSurvey of 522 individuals with stakeholder interest in SNAP, conducted in October through December 2011.ResultsThe top three barriers to improving dietary quality identified were: (i) unhealthy foods marketed in low-income communities; (ii) the high cost of healthy foods; and (iii) lifestyle challenges faced by low-income individuals. Many respondents (70 %) also disagreed that current SNAP benefit levels were adequate to maintain a healthy diet. Stakeholders believed that vouchers, coupons or monetary incentives for purchasing healthful foods might have the greatest potential for improving the diets of SNAP participants. Many respondents (78 %) agreed that sodas should not be eligible for purchases with SNAP benefits. More than half (55 %) believed retailers could easily implement such restrictions. A majority of respondents (58 %) agreed that stores should stock a minimum quantity of healthful foods in order to be certified as a SNAP retailer, and most respondents (83 %) believed that the US Department of Agriculture should collect data on the foods purchased with SNAP benefits.ConclusionsResults suggest that there is broad stakeholder support for policies that align SNAP purchase eligibility with national public health goals of reducing food insecurity, improving nutrition and preventing obesity.

The Supplemental Nutrition Assistance Program (SNAP), the largest federal food assistance program, currently serves 44.7 million Americans with a budget of $75 billion in 2011. This study engaged leading experts for in-depth, semi-structured interviews to explore their opinions concerning the existing challenges and barriers to eating nutritiously in SNAP. Experts also proposed strategies for improving nutritional status among SNAP recipients. Twenty-seven individuals were interviewed from advocacy, government, industry, and research organizations. Interviews were recorded, transcribed, coded and analyzed for thematic content. The high cost of nutrient-rich foods, inadequate SNAP benefits, limited access to purchasing healthy foods, and environmental factors associated with poverty were identified as barriers that influence nutrition among low-income households in the United States. Six themes emerged among respondents from diverse sectors about how to address these challenges including: 1) providing SNAP participants with incentives to purchase nutrient-rich food consistent with the 2010 Dietary Guidelines for Americans; 2) restricting the purchase of nutrient-poor foods and beverages with program benefits; 3) modifying the frequency of SNAP benefit distribution; 4) enhancing nutrition education; 5) improving the SNAP retailer environment and 6) increasing state and federal level coordination and consistency of program implementation. Given the recent dramatic increase in SNAP enrollment, policymakers must address existing barriers as well as consider new strategies to improve nutrition policies in SNAP so that the program can continue to address food insecurity needs as well as provide a healthful diet for SNAP beneficiaries.
