RESUMO
While food addiction has been positively associated with excess weight and disordered eating behaviors, this has not been examined in representative samples of emerging adults, who are at elevated risk for these outcomes. This study investigated relationships of food addiction with weight outcomes, weight perception, and weight-control behaviors in emerging adults and estimated the population attributable fraction to food addiction. Data from an observational cohort study were collected in seven annual waves from 2010 to 2016. A nationally representative sample of 2785 10th grade students was recruited from schools within each U.S. census region (73% participation) (mean ± SD baseline age = 16.3 ± 0.5years). Wave 7 retention was 81% (n = 2323, 60% female, mean ± SD = 22.6 ± 0.5 years). Outcomes included current BMI, BMI change from baseline - wave 7, increased weight status in wave 7 (increased weight status from baseline-wave 7), perceived overweight, dieting, any weight-control behavior, and extreme weight-control behaviors. Food addiction was measured in wave 7 using the modified Yale Food Addiction Scale. Relative risk of the outcomes associated with food addiction, and population attributable fraction, were estimated using adjusted log-binomial or robust Poisson regression analyses accounting for the complex survey design. Food addiction prevalence was 4.7%. Participants with food addiction were primarily females (91%); food addiction was uncorrelated with other sociodemographics. Food addiction was associated with 48%-167% increased RR for all outcomes, but these were attenuated after adjustment for confounders (31%-64%). The population attributable fraction for food addiction ranged from 2% (high wave 7 BMI) - 5% (extreme weight-control behaviors). Although the population attributable fraction estimates indicate that the public health burden of these outcomes attributable to food addiction may be relatively minor, food addiction may signal the presence of several adverse mental health symptoms.

BACKGROUND: Excessive intake of ultra-processed foods, formulated from substances extracted from foods or derived from food constituents, may be a modifiable behavioral risk factor for adverse maternal and infant health outcomes. Prior work has predominately examined health correlates of maternal ultra-processed food intake in populations with substantially lower ultra-processed food intake compared to the US population. This longitudinal study investigated relations of ultra-processed food intake with maternal weight change and cardiometabolic health and infant growth in a US cohort. METHODS: Mothers in the Pregnancy Eating Attributes Study were enrolled at ≤12 weeks gestation and completed multiple 24-Hour Dietary Recalls within six visit windows through one-year postpartum (458 mothers enrolled, 321 retained at one-year postpartum). The NOVA (not an acronym) system categorized food and underlying ingredient codes based on processing level. Maternal anthropometrics were measured throughout pregnancy and postpartum, and infant anthropometrics were measured at birth and ages 2 months, 6 months, and 1 year. Maternal cardiometabolic markers were analyzed from blood samples obtained during the second and third trimesters. RESULTS: Holding covariates and total energy intake constant, a 1-SD greater percent energy intake from ultra-processed foods during pregnancy was associated with 31% higher odds of excessive gestational weight gain (p = .045, 95% CI [1.01, 1.70]), 0.68±0.29 mg/L higher c-reactive protein during pregnancy (p = .021, 95% CI [0.10, 1.26]), 6.7±3.4% greater gestational weight gain retained (p = .049, 95% CI [0.03, 13.30]), and 1.09±0.36 kg greater postpartum weight retention (p = .003, 95% CI [0.38, 1.80]). No other significant associations emerged. CONCLUSIONS: Ultra-processed food intake during pregnancy may be a modifiable behavioral risk factor for adverse maternal weight outcomes and inflammation. Randomized controlled trials are needed to test whether targeting ultra-processed food intake during pregnancy may support optimal maternal health. TRIAL REGISTRATION: Clinicaltrials.gov.

BACKGROUND: Infant appetitive traits including eating rate, satiety responsiveness, food responsiveness, and enjoyment of food predict weight gain in infancy and early childhood. Although studies show a strong genetic influence on infant appetitive traits, the association of parent and infant appetite is understudied. Furthermore, little research examines the influence of maternal pregnancy dietary intake, weight indicators, and feeding mode on infant appetite. The present study investigated relations of maternal reward-related eating, pregnancy ultra-processed food intake and weight indicators, and feeding mode with infant appetitive traits. METHODS: Mothers in the Pregnancy Eating Attributes Study (458 mothers enrolled, 367 retained through delivery) completed self-report measures of reward-related eating, and principal component analysis yielded two components: (1) food preoccupation and responsiveness and (2) reinforcing value of food. Mothers completed 24-h dietary recalls across pregnancy, and the standardized NOVA (not an acronym) system categorized recalled foods based on processing level. Maternal anthropometrics were measured across pregnancy. At infant age 6 months, mothers reported on feeding mode and infant appetitive traits. Linear regressions were conducted predicting infant appetitive traits from household income-poverty ratio (step 1); maternal reward-related eating components (step 2); pregnancy ultra-processed food intake (% of energy intake), early pregnancy body mass index, and gestational weight gain (step 3); and exclusive breastfeeding duration (step 4). RESULTS: A 1-SD greater maternal food preoccupation and responsiveness was associated with 0.20-SD greater infant satiety responsiveness (p = .005). A 1-SD greater % energy intake from ultra-processed foods during pregnancy was associated with 0.16-SD lower infant satiety responsiveness (p = .031). A 1-SD longer exclusive breastfeeding duration was associated with 0.18-SD less infant food responsiveness (p = .014). Other associations of maternal reward-related eating, pregnancy ultra-processed food intake and weight indicators, and feeding mode with infant appetitive traits were non-significant. CONCLUSIONS: Proximal early-life environmental factors including maternal pregnancy dietary intake and feeding mode may facilitate or protect against obesogenic infant appetitive traits, whereas infant appetite may not parallel maternal reward-related eating. Further investigation into the etiology of appetitive traits early in development, particularly during solid food introduction, may elucidate additional modifiable risk factors for child obesity.

The potential negative effects of the COVID-19 pandemic on health-compromising behaviors including overeating, processed food intake, and alcohol use have been well documented. However, it is possible the COVID-19 pandemic has had positive effects on some health-promoting behaviors like cooking and fruit and vegetable intake. The current study was a preregistered secondary data analysis using data from a U.S. national, crowdsourced study (n = 868) on eating behaviors during the early stages of the COVID-19 pandemic. The objectives of the current study were to compare levels of cooking, fruit and vegetable intake, and physical activity among U.S. adults during the early stages of the COVID-19 pandemic to pre-pandemic levels in reference groups of U.S. adults, and test whether subjective stress from the pandemic was associated with health-promoting behaviors by obesity status. During the early stages of the COVID-19 pandemic, participants cooked more often and ate 0.23 more cups of fruits and vegetables per day, but 28.8% fewer participants met federal physical activity guidelines. Greater COVID-19 stress was minimally to moderately associated with greater cooking, fruit and vegetable intake, and physical activity. The positive association between COVID-19 stress and fruit and vegetable intake was stronger for individuals with obesity. The COVID-19 pandemic might have encouraged U.S. adults, especially those at risk for complications, to engage in some health-promoting behaviors while creating barriers for other behaviors.

Increased consumption of highly processed foods may result in lower diet quality, and low diet quality is associated with elevated risk of cardiovascular disease, type 2 diabetes, and cancer. One mechanism driving highly processed food intake is the expectation that eating these foods will improve emotional experiences, particularly in individuals with elevated "highly processed food addiction" symptoms. However, experimental findings about the emotional experiences following highly processed food intake are mixed. Furthermore, prior studies have generally failed to capture the potentially prolonged emotional effects of eating highly processed foods and not tested for individual differences. The present study was a preregistered archival data analysis of an ambulatory electronic diary study that captured real-life emotions following highly processed food intake. Multilevel modeling was used to predict the effects of highly processed food intake on subsequent positive and negative emotions immediately, 1 h, and 3 h after consumption. Intake of sweet high-fat foods, fast foods, and non-alcoholic sugary drinks was associated with greater positive emotions immediately after eating, and sweet high-fat food intake remained associated with greater positive emotions 1 h later. Sweet high-fat food and non-alcoholic sugary drink intake were associated with fewer negative emotions 1 h after consumption, and the negative association between non-alcoholic sugary drink intake and negative emotions was stronger for those with elevated highly processed food addiction symptoms. Overall, results suggest that highly processed food intake results in small alterations in positive and negative emotions immediately and up to 1 h after intake; however, these do not persist through 3 h after intake. The ability of highly processed foods to briefly alter emotions may be key to their reinforcing nature.

OBJECTIVE: Perceived stress, lower fruit intake, and comfort eating are all risk factors for chronic disease. The present pilot study aimed to simultaneously mitigate all three risk factors by applying Pavlovian conditioning to change the nature of comfort eating. Specifically, stressed participants underwent a Pavlovian conditioning intervention designed to elicit comforting effects of fruit intake and thereby reduce negative mood while promoting fruit intake. METHODS: We developed a seven-dose Pavlovian conditioning intervention wherein participants temporally paired together Progressive Muscle Relaxation (unconditioned stimulus) with fruit intake (conditioned stimulus) daily for 1 week. Participants (N = 100, mean [standard deviation] age = 20.7 [4.6] years; 74% female) with moderate to high levels of baseline perceived stress were randomized to the intervention or an active explicitly unpaired control group, wherein the Progressive Muscle Relaxation and fruit intake also occurred but were not temporally paired together. After the intervention, participants' negative mood was assessed immediately before and after fruit intake to assess conditioning effects. Then, participants logged their regular food intake for 4 days using the MyFitnessPal smartphone app. RESULTS: After the intervention, fruit intake acutely improved negative mood to a greater extent among the intervention versus control group (F(1,98) = 3.99, p = .048, = 0.039). However, there was not a significant between-group difference in intake of fruit or traditional comfort foods at postintervention. CONCLUSIONS: Repeated pairing of fruit intake with a reliable distress-reducing activity led to the conditioning of comforting effects of fruit intake. Further refinement of the intervention design is necessary to translate this conditioned association to actual intake of fruit and other foods.

The coronavirus SARS-CoV-2 (COVID-19) pandemic has created widespread stress. Since many people cope with stress by eating, the current study investigated whether eating behaviors shifted among U.S. adults after the emergence of the pandemic. Data from national, crowdsourced surveys conducted on March 31st, 2020 and February 13th, 2019 were compared. Average levels of eating to cope and food addiction symptoms did not appear to shift during the early stages of the pandemic; however, U.S. adults ate about 14% more added sugars. Moreover, greater stress in response to the pandemic was associated with greater eating to cope, added sugars intake, food addiction symptoms, drinking to cope, and drinking frequency. These associations differed by the presence of state-level stay-at-home orders, perceived vulnerability to disease, age, U.S. political party affiliation, and gender. Although eating behaviors did not appear to majorly shift during the early stages of the pandemic, stress from the pandemic may intensify some maladaptive coping tendencies among U.S. adults.

BACKGROUND: Alcohol craving, or the desire to drink alcohol, has been identified as a key experience preceding alcohol use. Alcoholics Anonymous has long claimed that individuals can allay alcohol cravings by eating sweets. Empirical tests of this strategy are limited to a few preclinical studies in rats, and there is no existing experiment testing the acute effect of eating sweets on alcohol cravings in humans. PURPOSE: The current study sought to experimentally test the acute effect of eating sweets on alcohol cravings in a sample with at-risk drinking. METHODS: After being exposed to an alcohol cue, individuals with at-risk drinking (N = 150) were randomly assigned to eat sweets (n = 60), eat calorie-equivalent bland food (n = 60), or watch a video (n = 30). Caloric amounts were manipulated. Individuals with at-risk drinking were then exposed to a second alcohol cue. Changes in alcohol cravings from after the first to after the second alcohol cue were measured via visual analog scale and heart rate. RESULTS: There were no significant between-group differences in changes in alcohol cravings. Caloric amounts did not modify effects. CONCLUSIONS: Experimental findings did not provide evidence to support the clinical lore that eating sweets can reduce alcohol cravings, albeit only acutely and for those with at-risk drinking. Other empirically supported strategies for managing alcohol cravings (e.g., pharmacotherapies, mindfulness) could instead be promoted.

Family history of substance use is a well-established risk factor for greater substance use in adolescence and adulthood. The biological vulnerability hypothesis proposes that family history of substance use might also confer risk for obesogenic eating behavior because of similar rewarding characteristics between substances and certain foods (e.g., processed foods high in refined carbohydrates and fat). Indeed, preliminary research shows that family history of substance use is linked with sweet liking and obesity in adults; however, it is unknown whether this factor is linked to eating behavior earlier in development. The present study (nâ¯=â¯52) tested the association of severity of parental nicotine dependence and alcohol use (drinking frequency, drinking quantity, binge drinking, and number of annual drinks consumed) with two types of child [Mageâ¯=â¯10.18 (0.83) years] eating behavior: homeostatic eatingbehavior, or eating regulated by internal satiety cues, and reward-driven eatingbehavior, or eating motivated by pleasure. Results indicated that-over and above the influence of child age, child biological sex, and family income-more severe parental nicotine dependence and frequent and/or heavy, frequent parental alcohol use were associated with significantly greater child reward-driven eating behaviors as indexed by the Food Responsiveness and Enjoyment of Food subscales on the Child Eating Behavior Questionnaire. Parental substance use was not associated with child homeostatic eating behavior as indexed by the Satiety Responsiveness subscale. Family history of substance use may be an important transdiagnostic risk factor that identifies children at risk for obesogenic, reward-driven eating behaviors.

Reducing intake of highly processed, energy-dense food may prevent chronic disease. One proposed intervention strategy for reducing intake of these foods is to increase non-food reward experiences (e.g., music, socializing, art) in their place. However, research supporting this strategy has yet to establish temporal order between non-food reward experiences and highly processed food intake, and has yet to test mediators. The current study sought to build upon this literature with an ambulatory electronic diary study wherein the time-specific associations between non-food reward experiences and highly processed food intake were observed. A sample of 84 young adults reported on multiple types of non-food reward experiences and highly processed food intake hourly for two weekdays and two weekend days through an application on their personal electronic devices. Time-lagged analysis was employed to predict the odds of highly processed food intake in the following hour from non-food rewards experienced in the current hour. Secondary (e.g., receiving positive social feedback) and hedonic (e.g., viewing pleasant images) non-food reward experiences in the current hour predicted greater instead of lower odds of highly processed food intake in the following hour. These associations were mediated by increased subjective pleasure. Purely eudaimonic (e.g., affirming values), social (e.g., cooperating with others), and primary (e.g., having sex) reward experiences generally did not predict odds of highly processed food intake in the following hour. These results suggest that-at least for young adults-many non-food reward experiences may fail to reduce highly processed food intake, and some may even backfire. A different intervention strategy targeting reward processes implicated in highly processed food intake (e.g., interfering with conditioned learned associations) may prove a more promising avenue for improving physical health.

PURPOSE: Comfort eating is a prevalent behavior. Prior research shows that comfort eating is associated with reduced stress responses and increased metabolic risk across adolescence, young adulthood, and middle adulthood. The purpose of the current research was to test if comfort eating prospectively predicted all-cause mortality in older adulthood. METHOD: The US Health and Retirement Study is an ongoing, nationally representative, longitudinal study of older adults. The final sample for the present study (N = 1445) included participants randomly selected to report how often they comfort ate. Comfort eating data were collected in 2008 and all-cause mortality data were collected in 2014. Participants also reported how often they consumed high-fat/sugar food as well as their height and weight in 2008. RESULTS: For each 1-unit increase in comfort eating, the expected odds of all-cause mortality (n = 255 deceased) decreased by 14%, OR = 0.86, p = 0.048, 95% CI [0.74, 0.99]. This analysis statistically accounted for other predictors of mortality in the sample including age, biological sex, race, highest educational degree attained, moderate and vigorous exercise, smoking, and cumulative illness. High-fat/sugar intake did not mediate (or diminish) the association but body mass index did. CONCLUSION: Comfort eating-irrespective of consuming high-fat/sugar food-may be associated with reduced mortality in older adults because it may promote greater body mass, and greater body mass is associated with lower risk of mortality in nationally representative samples. Interventionists might consider both beneficial and detrimental aspects of comfort eating across the lifespan.

Appetitive traits, including food responsiveness, enjoyment of food, satiety responsiveness and slowness in eating, are associated with childhood body mass index. Change in appetitive traits from infancy to childhood and the direction of causality between appetitive traits and body mass index are unclear. The present study examined the developmental trajectory of appetitive traits and their bidirectional relations with body mass index, from infancy to early childhood. Mothers in the Pregnancy Eating Attributes Study and follow-up (n = 162) reported child appetitive traits using the Baby and Child Eating Behaviour Questionnaires at ages 6 months and 3.5 years, respectively. Standardized body mass index (zBMI) was calculated from child anthropometrics. Cross-lagged panel models estimated bidirectional relations between appetitive traits and zBMI. Food responsiveness, satiety responsiveness and slowness in eating increased from infancy to early childhood. In cross-lagged panel models, lower infant satiety responsiveness (B ± SE = -0.45 ± 0.19, p = .02) predicted greater child zBMI. Infant zBMI did not predict child appetitive traits (p-values >.36). From infancy to early childhood, appetitive traits may amplify. Appetitive traits, particularly satiety responsiveness, appear to influence body mass index during this period, suggesting early intervention targeting these traits may reduce childhood obesity.

BACKGROUND: Ultra-processed food (UPF) is currently not included in most countries' dietary guidance. However, there may be growing public interest and consumer avoidance of UPF due to media reporting of studies on the negative health outcomes associated with UPFs. METHODS: We surveyed 2386 UK adults (M age = 45 years, 50% female) during February-April 2024. Participants completed measures on awareness of the term UPF, whether the UPF status of foods affects their dietary decision-making, and confidence in identifying UPFs. Participants categorised a list of 10 foods (5 UPFs and 5 non-UPFs) as UPF vs. not, before rating whether information about studies linking UPF to worse health impacts on their negative affect and acts as a deterrent to consuming UPFs. RESULTS: Most participants (73%) were aware of the term UPF and 58% reported that their food choices are determined by whether they believe a food is ultra-processed or not. Participants with the highest income and education levels were most likely to report both being aware of, and, avoiding consuming UPFs. Most participants could not accurately categorise whether foods were UPFs. Some sociodemographic groups (e.g., higher education levels) were more likely to accurately categorise UPFs but were also more likely to incorrectly believe that non-UPFs were UPFs. Participants tended to report that UPF-health risk information increases negative affect and acts as a deterrent to consuming UPFs. CONCLUSIONS: In this study, a large number of UK adults reported avoiding consuming UPFs. This was particularly pronounced among those with the highest education and income levels.
RESUMO
BACKGROUND: Appetitive traits and parent feeding styles are associated with body mass index in children, yet their associations with child diet quality are unclear. OBJECTIVE: The objective was to examine relations of appetitive traits and parental feeding style with diet quality in 3.5-year-old children. DESIGN: The study was a secondary, cross-sectional analysis of data from Sprouts, a follow-up study of the Pregnancy Eating Attributes Study (PEAS). Birthing parents completed the Child Eating Behavior Questionnaire, Caregiver's Feeding Styles Questionnaire, and proxy 24-hour dietary recalls for their children from February 2019 to December 2020. PARTICIPANTS/SETTING: Participants were 162 birthing parents (early pregnancy BMI ≥ 18.5 and absence of preexisting diabetes, any medical condition contraindicating study participation, self-reported eating disorder, or medications that could affect diet or weight) and their children living in North Carolina. MAIN OUTCOME MEASURES: Healthy Eating Index-2015 (HEI-2015) total scores were calculated. STATISTICAL ANALYSES PERFORMED: Path modeling was conducted using PROC CALIS with full information maximum likelihood (FIML) to account for missing data (< 2% of all data in dataset). Associations of child appetitive traits and parental feeding style with child HEI-2015 scores, adjusting for exclusive breastfeeding duration and household income-poverty ratio, were examined. Tests of simple effects were conducted in subsamples split by parental feeding style. Hypotheses were formulated during data collection. RESULTS: A 1-standard deviation (SD) greater food fussiness was associated with a 2.4-point lower HEI-2015 total score (P = .02; 95% confidence interval [CI] [-4.32, -0.48]) in children. When parental feeding style was authoritarian, a 1-SD greater food responsiveness was associated with a 4.1-point higher HEI-2015 total score (P = .007; 95% CI [1.12, 7.01]) in children. When parental feeding style was authoritative, a 1-SD greater slowness in eating was associated with a 5.8-point lower HEI-2015 total score (P = .01; 95% CI [-10.26, -1.33]) in children. CONCLUSIONS: Parental feeding style may modify the association of appetitive traits with diet quality in young children. Future research could determine whether matching parent feeding styles to child appetitive trait profiles improves child diet quality.

Food-related emotional expectancies influence food intake, yet little is known about their determinants. The present study objectives were to experimentally test how food advertisements affect food-related emotional expectancies in adults and whether effects differed by individual levels of "food addiction" symptoms. Participants (n = 718; Mage = 35.88, 36.8% with food addiction) were randomly assigned to watch video advertisements for highly processed foods, minimally processed foods, both food groups, or cellphones (control). Participants completed an attention check and questionnaires including the Anticipated Effects of Food Scale. Main effects of condition were non-significant. In participants with fewer symptoms of food addiction, watching video advertisements for highly processed foods increased expectancies that one would feel positive emotions while eating those foods, B(SE) = 0.40(0.16), p = 0.016, 95% CI (0.08, 0.72), ΔR2 = 0.03. Highly processed food advertisements may affect food-related emotional expectancies in adults who have not previously formed strong expectancies.

OBJECTIVE: The present study investigates the rates of co-occurrence among food addiction (FA), problematic substance use (alcohol, cannabis, cigarettes, nicotine vaping), parental history of problematic alcohol use, and obesity as an important step to understanding whether an addictive-like eating phenotype exists. METHOD: A community sample of 357 U.S. adults (49.7% male, 77.6% White, Mage 40.7) completed the Yale Food Addiction Scale 2.0 (YFAS2.0), the Alcohol Use Disorders Identification Test, the Cannabis Use Disorders Identification Test, the Fagerstrom Test for Nicotine Dependence, the E-Cigarette Dependence Scale, the Family Tree Questionnaire, and demographic/self-report body mass index questions through Amazon Mechanical Turk. Risk ratios (RRs; unadjusted and adjusted for sociodemographic covariates) were calculated using modified Poisson's regression. RESULTS: Risk of FA was higher in participants with problematic alcohol use (RR = 2.13, 99% CI [1.32, 3.45]), smoking (RR = 1.86, 99% CI [0.82, 3.36]), cannabis use (unadjusted; RR = 2.22, 99% CI [1.17, 4.18]), vaping (RR = 2.71, 99% CI [1.75, 4.21]), and parental history of problematic alcohol use (RR = 2.35, 99% CI [1.46, 3.79]). Risk of FA in participants with obesity was only higher in adjusted models (RR = 1.87, 99% CI [1.06, 3.27]). Obesity was not significantly associated with problematic substance use and parental history of problematic alcohol use. CONCLUSIONS: FA, but not obesity, co-occurred with problematic substance use and a parental history of problematic alcohol use. Results support the conceptualization of FA as an addictive disorder. The inclusion of FA as an addictive disorder in diagnostic frameworks is an important area of future consideration. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

PURPOSE: Child appetitive traits, eating styles that reflect responsiveness to external influences and internal hunger and satiety signals, are associated with eating behaviors and susceptibility to excess weight gain. However, relatively little is known about early life influences on child appetitive traits. This study investigated relations of early life maternal feeding behaviors and food exposures with appetitive traits at age 3.5 years. METHODS: Participants of the Pregnancy Eating Attributes Study (PEAS) and follow-up study were enrolled in early pregnancy and followed prospectively. This analysis included data collected from baseline through child aged 3.5-years (n = 160). Child appetitive traits at age 3.5 years were measured using the Child Eating Behavior Questionnaire. Age at introduction to fruit, vegetables, discretionary sweets, and discretionary savory foods was assessed, along with intake frequency at infant ages 6, 9, and 12 months, and 2 years. Maternal feeding to soothe was assessed at child aged 3, 6, and 12 months. Maternal permissive feeding was assessed at child aged 2 years. Multiple linear regressions estimated relations of maternal feeding behaviors and infant food exposures with child appetitive traits at age 3.5 years, controlling for sociodemographics and breastfeeding duration. RESULTS: Maternal feeding to soothe at 6 (r = 0.39, p < 0.001) and 12 months (r = 0.39, p < 0.001) was positively associated with permissive feeding at 2 years. Maternal feeding to soothe at 12 months and permissive feeding at 2 years were associated with greater child emotional overeating, emotional undereating, and desire to drink. Older age at introduction to fruit (ß = 0.20±0.08, p = 0.01) and younger age at introduction to discretionary sweet foods (ß = -0.07±0.04, p = 0.06) were associated with greater emotional overeating. Older age at introduction to vegetables (ß = 0.22±0.11, p = 0.04) and less frequent feeding of fruit (ß = -0.20±0.08, p = 0.01) were associated with greater food fussiness. CONCLUSIONS: Associations of emotional eating with parent feeding behaviors and early life food exposures suggest the potential for interventions targeting early life feeding to have long-term impact on child appetitive traits and diet quality.

Individual differences exist in perceived vulnerability to disease (PVD). PVD is associated with negative responses (e.g., disgust) towards individuals with obesity and heightened sensitivity regarding personal appearance. Through increasing fear of fat (FOF), PVD may be associated with cognitive restraint and compensatory behaviors. We utilized an adult sample (n = 247; 53.3% male sex assigned at birth) recruited through Amazon's MTurk prior to the COVID-19 pandemic to investigate associations between PVD, cognitive restraint and compensatory behaviors. Participants completed the Perceived Vulnerability to Disease Scale, Eating Disorder Diagnostic Scale, Dutch Eating Behaviors Questionnaire, and Goldfarb's Fear of Fat Scale. Mediation analyses were used to test our hypotheses. Perceived infectability (PVD-Infection) was associated with cognitive restraint and compensatory behaviors through increased FOF. Perceived germ aversion (PVD-Germ) was associated with cognitive restraint, but FOF did not mediate this association. Sex-stratified analyses revealed no significant sex differences. PVD may be an overlooked factor associated with cognitive restraint and compensatory behaviors in males and females. FOF was an important mediating factor in these associations. Increased engagement in cognitive restraint and compensatory behaviors may reflect attempts to reduce FOF. Future longitudinal research should explore whether PVD is a risk factor for cognitive restraint and compensatory behaviors.

Low diet quality during pregnancy and postpartum is associated with numerous adverse maternal and infant health outcomes. This study examined relations of ultra-processed food intake with diet quality during pregnancy and postpartum. Using data from 24-h recalls, ultra-processed food intake was operationalized as percent energy intake from NOVA-classified ultra-processed foods; diet quality was measured using Healthy Eating Index 2015 (HEI) total and component scores. Pearson correlations examined associations of ultra-processed food intake with HEI total and component scores, and food group intake was compared across four levels of ultra-processed food intake. On average, ultra-processed food comprised 52.6 ± 15.1% (mean ± SD) of energy intake in pregnancy and 50.6 ± 16.6% in postpartum. Ultra-processed food intake was inversely correlated with HEI total and 8 of 13 component scores. Compared to participants with the highest ultra-processed food intake (≥60% energy), those with the lowest ultra-processed food intake (<40% energy) had a 17.6-point higher HEI total score and consumed 2−3 times more fruit, vegetables, and seafood and plant proteins, and 1½ times more total protein. Additionally, they consumed 2/3 as much refined grains and 1/2 as much added sugar. Greater ultra-processed food intake was associated with lower diet quality across most HEI components. Reducing ultra-processed food intake may broadly improve adherence to dietary guidelines in pregnant and postpartum populations.

OBJECTIVE: Growing evidence suggests highly processed foods may trigger an addictive-like process, which is associated with obesity. Other research suggests an addictive-like process occurs in response to eating itself, rather than specific foods. Addiction-based obesity explanations raise concerns about double stigmatization of people with obesity and addiction. This study compared effects of obesity framings on external and internalized weight stigma. METHODS: The study was preregistered via Open Science Framework. Four hundred and forty-seven adults read an informational passage that described food addiction, eating addiction, or calorie balance explanations for obesity or a control passage about memory. Participants then completed external and internalized weight stigma measures. RESULTS: Participants in the food addiction condition reported higher internalized weight stigma compared with those in the control condition. Obesity framing did not significantly affect external weight stigma compared with the control. CONCLUSIONS: These findings suggest that food addiction explanations for obesity may elicit greater internalized weight stigma than non-obesity-related messages. Addiction-based and traditional obesity explanations do not appear to influence external weight stigma. Illuminating the effects of obesity framing on stigma will help researchers communicate discoveries in ways that mitigate stigma.
