Feeling bad or feeling good, does emotion affect your consumption of food? A meta-analysis of the experimental evidence

An Explorative Analysis of the Influence of Landscape Visual Aesthetic Quality on Food Preferences in Italy: A Pilot Study

As some previous research has highlighted, landscape characteristics are useful for improving the market share of some food products and the market power of companies in the agrifood sector. The purpose of this study is to verify whether the visual aesthetic quality of the landscape can influence food preferences and the willingness to pay for agrifood products. To this end, the preferences of 64 participants for three types of juice (orange, peach and pear) were analysed through a blind tasting experiment. Each participant tasted three pairs of fruit juices, one for each type of juice. The juices belonging to each pair were the same, but before tasting, the participants were shown two photos portraying the orchards where the fruits were produced, so participants were induced to think that the juices were different. The landscape associated with each pair of photographs had a different visual aesthetic quality (high or low). Participants were asked to provide three measures while tasting the juices: their overall juice assessment using a seven-point hedonic scale, the visual aesthetic quality of the photos on a seven-point Likert scale, and their willingness to pay as a percentage variation of the price that they usually pay to buy fruit juices. According to our results, the mean overall liking score and the mean willingness to pay percentage variation for the juices associated with a preferred landscape was higher and statistically different. Despite the need for further research, our results suggest that landscape acts as a proxy for quality in the evaluation of some food products and that the use of landscape photos could be a valid marketing strategy in agribusiness.

Measuring Ostracism-Induced Changes in Consumption of Palatable Food: Feasibility of a Novel Behavioral Task

Purpose

Ostracism is a highly aversive interpersonal experience. Previous research suggests that it can increase consumption of highly palatable food in some individuals, but decrease it in others. Thus, we developed the Cyberball-Milkshake Task (CMT), to facilitate research investigating individual differences in ostracism's effects on consumption of highly palatable food. We present data on feasibility for the CMT in a sample of young adult women.

Materials and Methods

Participants were 22 women, 18-30 years old, reporting very low or very high levels of emotional eating at screening. Participants performed the CMT, which consisted of 12 trials. Each trial included: playing a round of Cyberball (a computerized game of catch with fictitious "other participants" programmed to either include or exclude the participant); viewing a chocolate image; and then consuming a participant-determined amount of milkshake. Participants subsequently played an additional inclusion and exclusion round of Cyberball, each immediately followed by questionnaires assessing current mood and recent Cyberball experience.

Results

Cyberball exclusion (vs. inclusion) was associated with large, significant increases in reported ostracism and threats to self-esteem; exclusion's effects on affect were in the expected direction (e.g., increased negative affect), but generally small and non-significant. Milkshake intake was measurable for 95% of participants, on 96% of trials. Intake decreased quadratically across trials, with a steep negative slope for low trial numbers that decreased to the point of being flat for the highest trial numbers.

Discussion

The CMT is a generally feasible approach to investigating ostracism's effects on consumption of highly palatable food. The feasibility (and validity) of the CMT may benefit from modification (e.g., fewer trials and longer rounds of Cyberball). Future research should examine whether performance on a modified version of the CMT predicts real-world behavior in a larger sample.

Sugar-Sweetened Beverages and Depressive and Social Anxiety Symptoms Among Children and Adolescents Aged 7–17 Years, Stratified by Body Composition

Background

Rare studies investigated the associations between sugar-sweetened beverage (SSB) consumption with depressive and social anxiety symptoms among children and adolescents, particularly in different stratification of body composition, which was our purpose.

Methods

A cross-sectional survey of children and adolescents aged 7–17 years was conducted in Beijing, China, in 2020, with an average age of 12.07 (SD: 3.09) years. Children's Depression Inventory (CDI) questionnaires and social anxiety scale for children (SASC) were completed in the baseline questionnaires. SSB consumption and body composition were assessed using child-reported questionnaires and a GE Healthcare Lunar iDXA dual-energy X-ray bone densitometer. Multivariate logistic regression was used to assess the associations between SSB consumption with depressive and social anxiety symptoms. Confounders were evaluated by child-reported and parental questionnaires, including age, sex, parental educational attainment, maternal smoking status, single-child status, BMI, incomes, fruit consumption, physical activity, screen time, and the frequency of fried food consumption. Stratified analyses were performed to explore whether the associations were influenced by body composition.

Results

A total of 1,311 children and adolescents, including 658 boys and 653 girls, were included in the final analysis. There were 13.96 and 29.75% of the study population with depressive and social anxiety symptoms, respectively. Overall, about 63.77% of the children and adolescents consumed SSB, and the average SSB intake was 0.35 servings per day. In the fully adjusted model, compared to participants who did not consume SSB each day, SSB consumption of ≥1 servings/day was positively associated with depressive symptoms [odds ratio (OR) = 2.28, 95% CI = 1.30–4.01] and social anxiety (OR = 1.10, 95% CI = 0.69–1.77), though the latter did not reach statistical significance. When individuals had higher body fat or lower fat-free mass (FFM) or muscle, the ORs of depressive symptoms were more evident among children and adolescents who drank SSB for ≥1 servings/day (P < 0.05).

Conclusion

Higher consumption of SSB could be associated with increased OR of depressive symptoms in children and adolescents. The association remained robust, especially in groups with higher body fat or lower fat-free mass or muscle.

Hedonic Consumption in Times of Stress: Reaping the Emotional Benefits Without the Self-Regulatory Cost

Hedonic consumption is pleasant but can interfere with the capacity to self-regulate. In stressful moments, when self-regulation is arguably still important, individuals often indulge in hedonic consumption. In two experiments, we investigate whether hedonic consumption negatively affects self-regulation under moderately stressful conditions and whether selecting hedonic consumption under moderately stressful conditions is driven by high or low self-control. In both studies, participants were randomly exposed to a mental arithmetic task that was either completed under time pressure with performance feedback (moderate stress) or without time pressure and without feedback (no stress). Experiment 1 assigned participants to a hedonic (vs. neutral) consumption task and then measured impulse control via a color-word Stroop task. Experiment 2 measured self-control as a second independent variable and recorded hedonic (vs. neutral) consumption. The results show that moderate stress buffered the negative effect that hedonic consumption has on self-regulation under no stress conditions and that high rather than low self-control predicts hedonic over neutral consumption under stress. These findings indicate that hedonic consumption in response to moderate stress may be a strategic choice to reap the pleasure benefit of hedonic consumption while the costs to self-regulation are low.

Clustering individuals' temporal patterns of affective states, hunger, and food craving by latent class vector-autoregression

Background

Eating plays an important role in mental and physical health and is influenced by affective (e.g., emotions, stress) and appetitive (i.e., food craving, hunger) states, among others. Yet, substantial temporal variability and marked individual differences in these relationships have been reported. Exploratory data analytical approaches that account for variability between and within individuals might benefit respective theory development and subsequent confirmatory studies.

Methods

Across 2 weeks, 115 individuals (83% female) reported on momentary affective states, hunger, and food craving six times a day. Based on these ecological momentary assessment (EMA) data we investigated whether latent class vector-autoregression (LCVAR) can identify different clusters of participants based on similarities in their temporal associations between these states.

Results

LCVAR allocated participants into three distinct clusters. Within clusters, we found both positive and negative associations between affective states and hunger/food craving, which further varied temporally across lags. Associations between hunger/food craving and subsequent affective states were more pronounced than vice versa. Clusters differed on eating-related traits such as stress-eating and food craving as well as on EMA completion rates.

Discussion

LCVAR provides novel opportunities to analyse time-series data in affective science and eating behaviour research and uncovers that traditional models of affect-eating relationships might be overly simplistic. Temporal associations differ between subgroups of individuals with specific links to eating-related traits. Moreover, even within subgroups, differences in associations across time and specific affective states can be observed. To account for this high degree of variability, future research and theories should consider individual differences in direction and time lag of associations between affective states and eating behaviour, daytime and specific affective states. In addition to that, methodological implications for EMA research are discussed.

Eating and Control Styles Axis in Mentalisation-Based Psychotherapy in Eating Disorders: A Randomised Clinical Trial

Background

Clinicians need an instrument that helps their patients with eating disorders (ED) to explore their agent's inner intentions and confront negative behaviour and control styles.

Objectives

To assess the feasibility and impact of an eating and control styles axis (ECOSA) during the first 8 months of mentalisation-based psychotherapy with a community-based sample of ED patients.

Methods

Six experienced therapists and their consecutively admitted patients were randomly allocated to the intervention and control groups. A total of 94 women, M age = 24 were recruited between June 2020 and October 2021. Ninety completed it. Both groups received mentalisation-based psychotherapy, but only the intervention group used the ECOSA repeatedly. Therapists and participants were blinded to the study aims and hypothesis. Fidelity assessment was applied to ensure that the two groups differed mainly in terms of ECOSA usage.

Results

The use of ECOSA, although less than advised, was reported as feasible. The effect size of the improvement in reflective functioning was larger than that of the control group and correlated significantly only in the intervention group with EDE-Q score (r = 0.46; p = 0.001).

Conclusion

Although the study limitations: selective population, relatively small sample size and the lack of controlled confounder, the combined quantitative and qualitative results lend preliminary evidence for the validity and contribution of ECOSA as a possible instrument that may upgrade the clinician's toolbox in the treatment of ED. A more rigorous study design is needed to explore the potential usage of ECOSA as a clinical tool to enhance mentalisation among people with ED.

COVID-19 – Impact of the lockdown on the weight variation among the Lebanese population

The aim of this study is to assess lifestyle changes along with weight fluctuations during the COVID-19 lockdown in Lebanon. This cross-sectional study was conducted using a web-survey disseminated through social media platforms to a large sample of the Lebanese population between May 25th and June 8th, 2020, during the lockdown in Lebanon. Behavioral changes and weight variation during the confinement were assessed. Two thousand one hundred sixty-one participants (64.9% female) aged 18 to 78 years old were included in this study. On average, no net weight variation was reported by the participants. 59.3% of the smokers changed their smoking habits, 40.7% of the drinkers reported a decrease in alcohol consumption, 43.5% of the participants exercised less than one time weekly and 35.8% changed their diet. Increased frequency of physical activity, following a diet during lockdown, decreased weight dissatisfaction (P < 0.0001 for the three variables) were retained as significant factors associated with weight loss. Planning to engage in physical activity post lockdown was associated with weight gain (P = 0.021). In the Lebanese population, no net weight variation was reported during the lockdown. Increasing physical activity and initiating diet were associated with weight loss. Healthcare authorities should be alerted about the importance of these factors during the follow-up of the confined population.

Changes in Perceived Stress and Lifestyle Behaviors in Response to the COVID-19 Pandemic in The Netherlands: An Online Longitudinal Survey Study

The COVID-19 pandemic has substantial implications for physical and mental wellbeing. This study investigated changes, over time, in lifestyle behaviors and perceived stress during the initial phase of the pandemic and associations with COVID-19 symptoms, in the Dutch general population. An online longitudinal survey study was performed with pre-lockdown measurements in February, and subsequently in April and June 2020 (n = 259, mean age 59 ± 14 years, 59% women). Self-report questionnaires were used to assess weight, diet quality, physical activity, alcohol intake, and smoking. Perceived stress was measured using the validated perceived stress scale (PSS-10). The presence of COVID-19 symptoms (yes/no) was defined as fever, or >3 of the following symptoms: weakness/tiredness, muscle ache, dry cough, loss of smell/taste, and breathing difficulties. Data were analyzed using linear mixed models, adjusted for age, sex, educational level, marital status and (change in) employment status. Minimal increases over time were observed in alcohol intake (0.6 ± 0.7 to 0.7 ± 1.1 glasses/day, p = 0.001) and smoking (9.5 ± 8.7 to 10.9 ± 9.4 cigarettes/day among 10% smokers, p = 0.03), but other lifestyle behaviors remained stable. In April 2020, 15% reported COVID-19-related symptoms, and in June 2020, this was 10%. The presence of COVID-19 symptoms was associated with increased perceived stress (pinteraction = 0.003) and increased alcohol consumption (pinteraction = 0.03) over time. In conclusion, in this prospective study, COVID-19 symptoms were associated with increases in perceived stress and alcohol consumption. Future research on biopsychosocial determinants and underlying mechanisms of lifestyle changes, as a response to the COVID-19 pandemic, is needed.

Prone to food in bad mood-Emotion-potentiated food-cue reactivity in patients with binge-eating disorder

OBJECTIVE

Theories on emotional eating are central to our understanding of etiology, maintenance, and treatment of binge eating. Yet, findings on eating changes under induced negative emotions in binge-eating disorder (BED) are equivocal. Thus, we studied whether food-cue reactivity is potentiated under negative emotions in BED, which would point toward a causal role of emotional eating in this disorder.

METHODS

Patients with BED (n = 24) and a control group without eating disorders (CG; n = 69) completed a food picture reactivity task after induction of negative versus neutral emotions. Food-cue reactivity (self-reported food pleasantness, desire to eat [DTE], and corrugator supercilii muscle response, electromyogram [EMG]) was measured for low- and high-caloric food pictures.

RESULTS

Patients with BED showed emotion-potentiated food-cue reactivity compared to controls: Pleasantness and DTE ratings and EMG response were increased in BED during negative emotions. This was independent of caloric content of the images.

CONCLUSIONS

Food-cue reactivity in BED was consistent with emotional eating theories and points to a heightened response to all foods regardless of calorie content. The discrepancy of appetitive ratings with the aversive corrugator response points to ambivalent food responses under negative emotions in individuals with BED.

Oral Habits during the Lockdown from the SARS-CoV-2 Pandemic in the Romanian Population

Background and Objectives: The SARS-CoV-2 pandemic led to changes in population daily patterns. In order to adapt oral health promotion measures for future similar conditions, the main objective of the study was to assess changes in dental hygiene and eating and smoking habits during the government lockdown in Romania. Materials and Methods: The cross-sectional study was conducted immediately after the end of the lockdown and consisted of 800 adult subjects. Data collection was done via an online survey. Participants were divided into two groups: non-medical/dental practitioners (N-M/D group) and medical/dental practitioners (M/D group). Results: An increased use of dental floss from 27% (pre-lockdown) to 30.5% (during lockdown) was identified in the M/D group, while the manual toothbrush usage increased to 64.8% (during lockdown) from 61.7% (pre-lockdown) in the N-MD/group. No significant differences regarding toothbrushing frequency were observed in either group. A change in the number of daily snacks was identified in both groups (3–4 snacks per day: from 11% to 20.2% in the N-M/D group, from 13.1% to 22.2% in the M/D group). The consumption of sweets as a preferred snack was also noticed. A decrease of tobacco consumers was assessed in the lockdown period (from 66.6% to 60.4% in the M/D group, from 68.5% to 61.9% in the N-/M/D group). Conclusions: Oral habits were changed during the pandemic lockdown through the increase in the frequency of the consumption of snacks and sweets and the decrease in frequency of smokers. Only minor changes were observed in oral hygiene.

Predictors of negative psychosocial and health behavior impact of COVID-19 among young adults

Given the global impact of coronavirus disease 2019 (COVID-19) on mental and physical health, we examined young adults' changes in mental health, intimate relationship quality, alcohol use and weight-related behaviors during COVID-19 and their correlates (depressive symptoms, resilience, social context and COVID-19-related factors). We analyzed data from a longitudinal study of 1082 young adults across six metropolitan areas (Mage = 24.76 ± 4.70; 51.8% female; 73.6% White and 12.5% Hispanic), using multivariate linear regressions for continuous outcomes (magnitude of mental health impact) and logistic regressions for categorical outcomes (decreased relationship quality, physical activity and nutrition and increased alcohol use and sedentary behavior). Of five negative mental health impacts assessed, participants reported experiencing an average of 3.54 (SD = 5.46), experiencing more correlated with increased childcare responsibilities and lower resilience. Additionally, 23.6% of those in relationships experienced negative relationship impact, 41.3% increased alcohol use, 47.2% decreased physical activity, 74.0% were more sedentary and 34.7% experienced poorer nutrition, all of which was predicted by greater depressive symptoms. Additionally, lower resilience predicted negative relationship impact and poorer nutrition and social context/roles correlated with various outcomes (e.g. relationships and alcohol use). Interventions to reduce negative health behaviors given societal stressors should address key psychosocial and situational factors, including depressive symptoms and resilience.

The role of positive psychological constructs in diet and eating behavior among people with metabolic syndrome: A qualitative study

Positive Psychological (PP) constructs (e.g., optimism and gratitude) may impact the adherence to healthy behaviors, including diet, though prior studies have shown mixed findings. This qualitative study explored the relationships between PP constructs and dietary behaviors among 21 adults with metabolic syndrome through semi-structured interviews. Directed content analysis led to five themes: eating healthfully leads to PP constructs, PP constructs lead to eating healthfully, eating healthfully prevents negative emotions, healthy behaviors associated with diet, and an upward healthy spiral. Given the close relationship between PP constructs and diet, these may be targeted to improve diet in risk populations through interventions that promote well-being.

Self-reported emotional eaters consume more food under stress if they experience heightened stress reactivity and emotional relief from stress upon eating

Group data means from individuals who self-assess as emotional eaters do not reliably show increased food intake in response to stress or negative emotions. This inconsistency in predictive validity of self-reported emotional eating (EE) could be attributable to unconsidered moderation of the relationship between self-reported EE and behavioral measures of EE. Greater emotional relief from stress by eating may provide enhanced negative reinforcement and promote future EE in response to stress as a form of self-medication. Thus, we predicted that greater emotional relief from stress by eating (decrease in negative affect from stress to post-eating) would moderate the extent to which heightened stress reactivity (measured by systolic blood pressure, SBP) moderates the relationship between self-reported EE and food intake post-stress. We also hypothesized that self-reported EE would not predict greater food consumption on the rest day. 43 undergraduate women completed online assessments of eating behaviors. Participants were given snacks to eat after a mental stress task (TSST) or rest period on separate days in counterbalanced order. Our prediction was supported, as the moderated moderation model (PROCESS model 3) was highly significant on the stress day. Self-reported EE predicted increased food intake post-stress only under conditions of high stress reactivity and high emotional relief. On the rest day, self-reported EE predicted greater snack food intake only when SBP was high. This conditional increased intake substantiates stress as a promoter of snack food consumption for women with greater EE. Overall, our findings identified factors that may distinguish the subset of self-reported emotional eaters who are more likely to display EE behaviors in a laboratory setting, yet further studies are needed to directly test whether negative reinforcement via emotional relief from stress by eating drives enhanced EE following stress.

Genotoxic effect of microplastics and COVID-19: The hidden threat

Microplastics (MPs) are ubiquitous anthropogenic contaminants, and their abundance in the entire ecosystem raises the question of how far is the impact of these MPs on the biota, humans, and the environment. Recent research has overemphasized the occurrence, characterization, and direct toxicity of MPs; however, determining and understanding their genotoxic effect is still limited. Thus, the present review addresses the genotoxic potential of these emerging contaminants in aquatic organisms and in human peripheral lymphocytes and identified the research gaps in this area. Several genotoxic endpoints were implicated, including the frequency of micronuclei (MN), nucleoplasmic bridge (NPB), nuclear buds (NBUD), DNA strand breaks, and the percentage of DNA in the tail (%Tail DNA). In addition, the mechanism of MPs-induced genotoxicity seems to be closely associated with reactive oxygen species (ROS) production, inflammatory responses, and DNA repair interference. However, the gathered information urges the need for more studies that present environmentally relevant conditions. Taken into consideration, the lifestyle changes within the COVID-19 pandemic, we discussed the impact of the pandemic on enhancing the genotoxic potential of MPs whether through increasing human exposure to MPs via inappropriate disposal and overconsumption of plastic-based products or by disrupting the defense system owing to unhealthy food and sleep deprivation as well as stress. Overall, this review provided a reference for the genotoxic effect of MPs, their mechanism of action, as well as the contribution of COVID-19 to increase the genotoxic risk of MPs.

Stress-induced alterations in HPA-axis reactivity and mesolimbic reward activation in individuals with emotional eating

BACKGROUND

Emotional eating has emerged as a contributing factor to overeating, potentially leading to obesity or disordered eating behaviors. However, the underlying biological mechanisms related to emotional eating remain unclear. The present study examined emotional, hormonal, and neural alterations elicited by an acute laboratory stressor in individuals with and without emotional eating.

METHODS

Emotional (n = 13) and non-emotional eaters (n = 15) completed two main study visits, one week apart: one visit included a Stress version and the other a No-stress version of the Maastricht Acute Stress Task (MAST). Immediately pre- and post-MAST, blood was drawn for serum cortisol and participants rated their anxiety level. After the MAST, participants completed a Food Incentive Delay (FID) task during functional magnetic resonance imaging (fMRI), followed by an ad libitum snack period.

RESULTS

Emotional eaters exhibited elevated anxiety (p = 0.037) and cortisol (p = 0.001) in response to the Stress MAST. There were no changes in anxiety or cortisol among non-emotional eaters in response to the Stress MAST or in either group in response to the No-stress MAST. In response to the Stress MAST, emotional eaters exhibited reduced activation during anticipation of food reward in mesolimbic reward regions (caudate: p = 0.014, nucleus accumbens: p = 0.022, putamen: p = 0.013), compared to non-emotional eaters. Groups did not differ in snack consumption.

CONCLUSIONS

These data indicate disrupted neuroendocrine and neural responsivity to psychosocial stress amongst otherwise-healthy emotional eaters, who demonstrated hyperactive HPA-axis response coupled with hypoactivation in reward circuitry. Differential responsivity to stress may represent a risk factor in the development of maladaptive eating behaviors.

Dynamic associations between anxiety, stress, physical activity, and eating regulation over the course of a behavioral weight loss intervention

Negative emotional experiences are associated with dysregulated eating behaviors that impede weight management. While weight loss interventions promote physical activity and self-regulation of eating, no studies have examined how physical activity may directly influence eating by attenuating associations between negative emotions and eating.

OBJECTIVE

The current study examined how momentary negative emotions (stress and anxiety), moderate-to-vigorous intensity physical activity (MVPA), and their interactions predict eating dysregulation (i.e., intensity of eating temptations, inability to resist eating tempting foods, overeating), as well as how these associations change during a weight loss intervention.

METHODS

Women with overweight/obesity (N = 55) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after a three-month internet-based weight loss program.

RESULTS

Three-way interactions emerged predicting overeating and eating tempting foods. When women experienced higher than usual levels of momentary anxiety or stress at end-of-treatment, they were less likely to subsequently overeat or eat tempting foods when they had recently engaged in more MVPA (relative to their usual level). No significant associations were found for ratings of temptation intensity.

CONCLUSIONS

Findings suggest MVPA may exert direct effects on eating regulation. Specifically, MVPA appears to increasingly buffer the effect of negative emotional states on dysregulated eating behavior over the course of a weight loss intervention. Future work is needed to develop ways of communicating to patients how activity can have both indirect and direct effects on body weight, and examine whether such knowledge improves outcomes.

Negative affect, childhood adversity, and adolescents' eating following stress

Obesity commonly emerges by adolescence and is associated with serious health consequences. Emotional eating (consuming calories, fats, and sugars in response to negative affect) may promote obesity; however, evidence is mixed as to whether negative affect increases obesogenic eating. Early-life adversity may shape malleable neurobiological systems that govern inhibitory control, physiological regulation, coping strategies, and eating behavior, contributing to greater obesogenic eating in response to negative affect. Therefore, this study tested whether childhood adversity moderates the association between negative affect and food consumption in a diverse sample of female adolescents. After completing a childhood adversity assessment, 157 female adolescents (13-17 years; 28.7% African American, 39.5% Hispanic/Latina, 31.8% Non-Hispanic White) rated their negative affect in response to a standard social stress paradigm before consuming a buffet lunch, which was evaluated for calories, added sugars, and solid fats consumed. Results did not support that negative affect exerted a main effect on eating behavior. However, negative affect and childhood adversity interacted to predict calories and solid fats consumed, such that negative affect was associated with more obesogenic eating for those with high adversity exposure but not for those with low adversity exposure. Adversity and affect did not interact to predict added sugars consumed. Findings support that eating patterns in response to negative affect may differ by childhood adversity history. Reducing children's adversity exposure and bolstering emotion regulation techniques for adolescents who have been exposed to adversity may provide pathways to protect health and well-being by reducing maladaptive eating patterns.

The Association of Restrained Eating and Overeating during COVID-19: A Cross-Lagged Model

Widespread overeating has been found during the 2019 coronavirus (COVID-19) pandemic. The present study investigated whether pre-pandemic restrained eating (RE) predicted overeating during the pandemic, and further explored the behavioral (mortality threat, negative affect) mechanisms underlying this association. An eight-month longitudinal survey was conducted with a large sample of 616 undergraduates from Southwest university. From September 2019 to April 2020, three measurements were conducted. RE was tested before the pandemic (T1), and data of mortality threat, negative affect, and overeating were collected at the middle (T2) and end of (T3) the COVID-19 crisis in China. The correlation results showed that baseline RE was positively associated with mortality threat, negative affect, and overeating at T2 and T3. Moreover, negative affect and mortality threat were positively correlated with overeating. Results from longitudinal mediation showed that baseline RE would positively predict T3 overeating through T2 negative affect, but not T2 mortality threat. This study supports and extends the counterregulatory eating hypothesis that RE positively predicts future overeating, especially through negative emotions. These findings further reveal the core psychological mechanism underlying this positive RE-overeating relation in the context of COVID-19, indicating that the individuals with higher RE could not cope with negative affect adequately, contributing to more overeating.

Negative Affect and Maladaptive Eating Behavior as a Regulation Strategy in Normal-Weight Individuals: A Narrative Review

Emotions have a powerful influence on eating behavior, and eating behavior can have a powerful effect on emotions. The objective of the present narrative review was to evaluate the relationship between negative affect and maladaptive eating behavior as a regulation strategy in normal-weight individuals. A search of the literature within PubMed®, MEDLINE® and PsycINFO was conducted using a combination of the following terms: “affect”, “negative affect”, “affect regulation” and “maladaptive eating behavior”. A total of 106 papers were identified for full text review and were included in the final set of literature. The manuscript presents an overview of the literature on negative affect and maladaptive eating behavior. It offers a brief overview of restrained, uncontrolled and emotional eating in normal-weight individuals and looks at maladaptive eating behavior used to regulate their affect. Based on the previous research findings, we argue that using more adaptive strategies for emotion regulation (cognitive reappraisal) might result in downregulating integral negative affect to food and in improving eating behavior.

Emotional eating behaviors during the COVID-19 pandemic: A cross-sectional study

Background & aims

The study aimed to evaluate emotional eating tendency of Turkish individuals during COVID-19 pandemic.

Methods

The study comprised an online questionnaire and it was conducted from August to September 2020. The survey was distributed through social networks.

Results

A total of 1626 adults have been included in the study, aged between 18 and 65 years (69.6% females and 30.4% males). The average BMI of all participants was 24.4 ± 4.7 kg/m², 6% were underweight, and 11.6% were obese. A total of 32.7% of the participants had an increase in appetite and 34.4% had a weight gain. It was found that most of the participants (75.7%) were emotional eaters at different levels. Emotional eating was more common in obese people (43.5%) than normal weight (33.5%) and underweight (18.4%) people. It was examined the increasing food intake according to the BMI, the obese increased the consumption of fresh vegetables, fruits, pastries, and, eggs; underweight increased the consumption of fresh vegetables and fruits, milk and, eggs. As in other countries, a weight gain was observed in the individuals. However, the participants resorted to emotional eating to cope with negative emotions such as depression, anxiety, and stress caused by the pandemic.

Conclusions

In this study, it has been provided preliminary data that can be used in future studies to determine the emotional eating behaviors during the COVID-19 pandemic.

Impact of COVID-19 lockdown on the perception of home meals and meal-related variables: a large-scale study within the Italian population during the acute phase of the pandemic

Italy was the first European country struck by the COVID-19 epidemic and experienced a national lockdown. This study explored the effect of lockdown on the perception of any meals prepared and/or conducted at home (home meals) and investigated which variables played a role in this. A group of Italians (n=3,060) not suspected/diagnosed as having COVID-19 (18-91 years old; 33% males) completed an online survey during the first lockdown (April 2020). Liking for home meals either increased (51% of the population) or did not vary (43%), while it decreased for only 6% of respondents. Total meal intake similarly either increased (51%) or remained unchanged (33%). Core variables describing meal perception (Liking for meal, Pleasure in meal preparation, Meal duration, Meal Time, Overall food intake, Snack intake) were positively associated with each other. Two clusters with different perceptions of home meals were found, characterised by an increased appreciation (Cl1, 61%) and an unchanged appreciation (Cl2, 39%), respectively. In the acute phase of lockdown, increased meal pleasure was associated with home togetherness (not living alone), cooking with others more often, having high cooking dynamism (use of different kitchen tools, engaging in online food-related activities like using online recipe/website for cooking, use of ready-to-eat meal delivery), and being young, a student or a worker (Cl1). Conversely, Cl2 showed an unchanged meal pleasure, and it was mostly associated with living alone (before and during lockdown), being elderly, retired, widowed, having a low degree of cooking-related activities and dedicating a small weekly budget to food. Variables strictly describing the meal were discussed. Lockdown did not homogenously affect the population in terms of meal pleasure, and high enjoyment of meals was related to high meal involvement. Younger subjects seemed to be more resilient and appreciated meals more due to high cooking dynamism, food-related activities and togetherness. Public health policies could consider these outputs to set up interventions that use meal-dedication activities to increase meal pleasure in vulnerable targets or in subjects experiencing poorly appreciated diets in similar future stressful situations.

Changes in Eating Habits and Lifestyles in a Peruvian Population during Social Isolation for the COVID-19 Pandemic

BACKGROUND

Peru has one of the highest infection and death rates in the world for the COVID-19 pandemic. The government implemented house confinement measures with probable consequences on lifestyle, particularly affecting eating habits, physical activity, sleep quality, and mental health.

OBJECTIVES

The aim of this study was to assess the lifestyles, physical activity, and sleep characteristics, as well as changes in eating habits in a Peruvian population during the first wave of the COVID-19 pandemic.

METHODS

A cross-sectional descriptive study was performed. We analyzed Peruvian adults based on an online self-administered questionnaire divided into sociodemographic, anthropometrics, COVID-19 diagnosis reported, lifestyle habits, and frequency of consumption of foods.

RESULTS

During confinement for COVID-19, 1176 participants were studied. Of these, most reported weight gain (1 to 3 kg) and 35.7% were overweight. The lifestyles habits showed that 54.8% reported doing physical activity and 37.2% sleep less. The Peruvian sample presented a main meal pattern of breakfast (95.7%), lunch (97.5%), and dinner (89.1%). Likewise, eating habits before and during COVID-19 pandemic showed that vegetables (OR:1.56, CI95% 1.21-200), fruit (OR: 1.42, CI95% 1.10-1.81), legumes (OR:1.67, CI95% 1.23-2.28), and eggs (OR: 2.00, CI95% 1.52-2.65) presented significant consumption increase during social isolation, while bakery products (OR: 0.74, CI95% 0.56-0.97), meat, snack, refreshment, and fast food decreased in consumption. Other foods showed no significant differences.

CONCLUSION

This study showed an important frequency of overweight and sleep changes. There was a slight increase in physical activity despite the social isolation measures and an increase in healthy eating habits; nevertheless, the majority reported gaining weight.

The effect of mood on food versus non-food interference among females who are high and low on emotional eating

BACKGROUND

Emotional eating refers to overeating triggered by emotional experiences and may cause significant psychological distress and health problems. Thus, it is important to better understand its underlying mechanisms. The study examined if the ability to ignore task-irrelevant information, namely, interference control, is modulated by mood and exposure to food stimuli among females who are high and low on emotional eating.

METHOD

The study's sample included 80 women who were high (N = 40) or low (N = 40) on an emotional eating scale. Participants were divided to a negative or neutral mood induction group. Following the mood induction, they completed a food-flanker task that allowed assessing attentional interference caused by food and non-food stimuli separately.

RESULTS

The low emotional eating group had significantly greater food compared to non-food interference, suggesting difficulty at ignoring food stimuli while attending a neutral target. In the high emotional eating group, there was no difference between food and non-food interference. However, higher levels of emotional eating predicted lower levels of food interference.

CONCLUSION

The pattern of results suggests a food-avoidance attentional tendency among those with higher levels of emotional eating. The mood manipulation did not influence food-related interference in either group. The lack of an effect of mood on food-related interference questions the impact of negative emotions on basic attentional processes among individuals with emotional eating.

Stress Responsiveness and Emotional Eating Depend on Youngsters' Chronic Stress Level and Overweight

The persistent coexistence of stress and paediatric obesity involves interrelated psychophysiological mechanisms, which are believed to function as a vicious circle. Here, a key mechanistic role is assumed for stress responsiveness and eating behaviour. After a stress induction by the Trier Social Stress Test in youngsters (n = 137, 50.4% boys, 6–18 years), specifically those high in chronic stress level and overweight (partial η² = 0.03–0.07) exhibited increased stress vulnerability (stronger relative salivary cortisol reactivity and weaker happiness recovery) and higher fat/sweet snack intake, compared to the normal-weight and low-stress reference group. Stress responsiveness seems to stimulate unhealthy and emotional eating, i.e., strong cortisol reactivity was linked to higher fat/sweet snack intake (β = 0.22) and weak autonomic system recovery was linked to high total and fat/sweet snack intake (β = 0.2–0.3). Additionally, stress responsiveness acted as a moderator. As a result, stress responsiveness and emotional eating might be targets to prevent stress-induced overweight.

Managing the premenstrual body: a body mapping study of women's negotiation of premenstrual food cravings and exercise

BACKGROUND

Women's eating behaviours and exercise patterns have been found to fluctuate across the menstrual cycle, manifested by premenstrual food cravings and reduced exercise. However, the meaning and consequences of premenstrual changes in eating and exercise behaviours remains underexplored. The aim of this qualitative study was to explore how women who feel negatively about their premenstrual bodies construct and experience premenstrual changes to eating and exercise practices, which disrupt their usual patterns of body management.

METHODS

Four hundred and sixty women aged 18-45 completed an online survey in response to a Facebook advertisement targeted at women who feel negatively about their bodies during the premenstrual phase of the cycle. Participants reported moderate premenstrual distress, high body shame and high risk of disordered eating attitudes using standardised measures. Sixteen women reporting rich accounts of premenstrual body dissatisfaction were invited to participate in body-mapping, involving visually illustrating experiences on a life-sized outline of the body, followed by a telephone interview. Thematic analysis was used to explore qualitative survey, interview, and body-mapping data.

RESULTS AND DISCUSSION

Results found that outside of the premenstrual phase these women engaged in restrictive eating and intensive exercise behaviours, which were disrupted by premenstrual cravings, hunger, fatigue, pain and feeling physically uncomfortable. For a minority of the women, this facilitated self-care in reducing the strict management of their bodies during the premenstrual phase. Others experienced feelings of guilt, shame, self-disgust and pushed their bodies physically through increased exercise.

CONCLUSIONS

These findings emphasise the need to acknowledge changes in body management across the menstrual cycle, with implications for women's mental health and feelings about the self. Internalisation of pressures placed on women to manage their bodies through restrictive eating behaviours and rigorous exercise plays a role in women's premenstrual body dissatisfaction and distress. The current study aimed to explore how women who feel negatively about their premenstrual bodies construct and experience premenstrual changes to eating and exercise practices. Outside of the premenstrual phase these women engaged in restrictive eating and intensive exercise behaviours which were disrupted by premenstrual cravings, hunger, fatigue, pain and feeling physically uncomfortable. Some women allowed themselves to take a premenstrual break from their usual strict eating and exercise behaviours, whereas others felt guilt, shame, self-disgust and physically pushed their bodies through increased exercise. These findings emphasise that changes to eating and exercise behaviours across the menstrual cycle and pressures placed on women to manage their eating and exercise behaviours have implications for women's premenstrual distress and body dissatisfaction.

Humor and Hunger Affect the Response Toward Food Cues

The omnipresence of food cues in everyday life has been linked to troubled eating behavior and rising rates of obesity. While extended research has been conducted on the effects of negative emotions and stress on food consumption, very little is known about how positive emotions affect eating and particularly attention toward food cues. In the present study, we investigated whether humor impacts attentional bias toward food and whether it will affect preferences for healthy and unhealthy food items, depending on the hunger state. To do so, a group of randomly assigned participants watched funny video clips (humor group, N = 46) or neutral ones (control group, N = 49). Afterwards, they performed a modified Posner cueing task with low or high caloric food images serving as cues. We found a significant group × hunger interaction. Compared to the control group, the humor group responded more slowly to food cues when hungry, whereas the opposite was true when participants were satiated. Additionally, our results suggest that hunger possibly directs attention away from healthy food cues and toward unhealthy ones. No group differences were found with respect to food preferences and engagement and disengagement of attention. We discuss the potential of humor in counteracting aversive consequences of hunger on attention allocation toward food. We propose an underlying mechanism involving a combined reduction in cortisol levels and a decrease in activation of the reward system. However, given the novelty of the findings, further research is warranted, both to replicate the results as well as to investigate the suggested underlying processes.

Sharp Increase in Eating Disorders among University Students since the COVID-19 Pandemic

The COVID-19 pandemic has caused stress as well as modified physical activity and eating habits among university students. The objectives were to identify the changes in body mass index (BMI) and eating disorders among university students between 2009 and 2021. Between 2009 and 2021, five repeated cross-sectional studies were conducted among university students who filled in an anonymous online self-questionnaire. Age, gender, and BMI were recorded, and the SCOFF questionnaire was used for ED screening which, in combination with BMI, allows to identify the four broad categories of ED with the Expali algorithm. With the five studies, 8981 university students were included in total. Obesity steadily increased between 2009 and 2021, for both men and women. The prevalence of ED was stable between 2009 and 2018 and significantly increased from 31.8% in 2018 to 51.8% in 2021 for women (p _trend < 0.0001), and from 13.0% in 2009 to 31.3% in 2021 for men (p _trend < 0.0001). All types of ED increased significantly between 2009 and 2021, except for restrictive ED among men. These results indicate for the first time a significant increase in ED prevalence among students since the COVID-19 pandemic. Initiatives to reinforce early screening of ED to implement targeted interventions in the student population are urgently needed.

The Impact of Coronavirus COVID-19 Pandemic on Food Purchasing, Eating Behavior, and Perception of Food Safety in Kuwait

During the COVID-19 pandemic, the government in Kuwait implemented public health measures to control the spread of the virus. However, despite the importance of these restrictions, normal activities related to purchasing of groceries, concerns related to food safety, and overall uncertainty may have influenced food behaviors and food consumption. Hence, the study investigates the impact of COVID-19 on food purchasing behaviors, eating behaviors, and the perception of food safety and security among residents in Kuwait. A cross-sectional study was carried out using self-administered questionnaires between 28 July 2020 and 31 August 2020 during the COVID-19 pandemic in Kuwait. A total of 841 respondents participated in the study. The study identified several changes in food purchasing behaviors, eating behaviors, food consumption, and consumers perceptions on food safety during the pandemic. The closures, restrictions, and changes in food purchasing evidently influenced individual’s eating behaviors. Largely, participants were found to (i) change their food purchasing behavior (74%); (ii) opt for online food delivery services (42.8%); (iii) purchase long-shelf-life foods (e.g., canned food and dry staples) (76%); (iv) consume more meals at home (76%); and (v) follow public health measures to reduce the spread of the virus and ensure their safety (98%). This study indicates that individuals during times of uncertainty and stress change their food purchasing behaviors, food consumption habits, and follow guidelines and recommendations. These findings may help public health initiatives to focus on raising awareness about the importance of health, wellbeing, and nutrition during times of crises.

Emotion and Psychophysiological Responses During Emotion-Eliciting Film Clips in an Eating Disorders Sample

Background: Greater vulnerability to negative emotions appears associated with the development and maintenance of eating disorders (EDs). A systematic review of psychophysiological studies using emotion-eliciting film clips reveals that there are no studies examining the effect of standardized validated film clips on psychophysiological response across a range of EDs.

Methods: Using standardized validated film clips without ED-specific content, the present study examined self-reported emotions and psychophysiological responses of women with Binge-Eating Disorder (BED; n = 57), Anorexia Nervosa (AN; n = 16), Bulimia Nervosa (BN; n = 34), and Healthy Controls (HCs; n = 26) at Baseline, during Neutral, Sad, Happy, and Fear-inducing film clips, and at Recovery.

Results: Throughout the protocol, the ED groups reported significantly greater sadness and anxiety than HCs. Additionally, the AN group reported more fear, the BED group more frustration, and the BED and BN groups more tension than HCs. Compared to HCs, the BED group reported stronger urges to binge throughout the protocol, whereas BN group reported stronger urges to binge relative to the HC group only at Baseline and Recovery. The BN and BED groups experienced decreased urges to binge during all film clips compared to Baseline. Respiratory Sinus Arrhythmia levels were significantly lower in the BED group compared to HCs and the BN group throughout the protocol.

Discussion: Standardized validated film clips can be used to elicit expected self-reported emotion and skin conductance responses in ED groups, although individuals with EDs compared HCs report greater negative emotions. Interestingly, film clips appeared to reduce urges to binge in binge-eating groups.

Positive and Negative Emotional Eating Are Not the Same-The Spanish Version of the Positive-Negative Emotional Eating Scale (PNEES)

The literature points to the importance of distinguishing between positive and negative emotional eating in relation to overeating and binge eating. The aim of this study was to evaluate the Spanish version of the Positive-Negative Emotional Eating Scale (PNEES) in a Spanish community sample. The sample consisted of 628 participants. The mean age was 27.5 (SD = 12.7) and 70.1% of them were women. The participants completed the PNEES, and measures of anxiety and depression (HADS), and eating disorder-related scales (TFEQ-R18, BULIT-R, and EAT-26) that were selected to examine convergent validity. A confirmatory factor analysis was conducted, replicating the original two-factor solution, consisting of Negative Emotional Eating (PNEES-N) and Positive Emotional Eating (PNEES-P). The results showed an acceptable fit of the model (CFI = 0.986; TLI = 0.984, RMSEA = 0.055). Internal consistency ranged from ω = 0.92 to ω = 0.96 for both subscales and the total score. PNEES-P correlations with other variables were lower with respect to the PNEES-N, showing that they are different constructs. A mediation analysis was conducted, in which PNEES-P significantly predicted binge eating and PNEES-N was a partially mediator variable. The results showed that the adaptation process was successful.

Bad mood food? Increased versus decreased food cue reactivity in anorexia nervosa and bulimia nervosa during negative emotions

OBJECTIVE

Emotion regulation difficulties in anorexia nervosa (AN) and bulimia nervosa (BN) might underlie bingeing and purging in BN, extreme fasting in AN, or combinations of these symptoms in binge-purge type AN. In this study, we tested for decreased food cue reactivity in response to negative emotions in AN, and the opposite pattern for BN. Furthermore, we explored subgroup differences (restrictive vs. binge-purging AN; history of AN in BN).

METHOD

Patients with AN (n = 41), BN (n = 39), and matched controls (n = 70) completed an emotional eating questionnaire. In a laboratory experiment, we induced negative emotions and measured food cue reactivity (pleasantness, desire to eat (DTE), and corrugator muscle activity).

RESULTS

AN reported emotional undereating, while BN reported emotional overeating. In the laboratory task, BN showed increased DTE and an appetitive corrugator response during negative emotions, selectively towards high-calorie foods. AN showed generalized reduced cue reactivity to high-calorie food regardless of emotional state. This pattern appears to be characteristic of restrictive AN, while cue reactivity of both BN subgroups pointed towards emotional overeating.

CONCLUSIONS

The emotional over- versus undereating framework might help to explain bingeing and restricting along the anorectic-bulimic disorder spectrum, which calls for novel transdiagnostic theories and subgroup-specific treatments.

Food Desires, Negative Emotions and Behaviour Change Techniques: A Computational Analysis

Behaviour change techniques are considered effective means for changing behaviour, and with an increase in their use the interest in their exact working principles has also expanded. This information is required to make informed choices about when to apply which technique. Computational models that describe human behaviour can be helpful for this. In this paper a few behaviour change techniques have been connected with a computational model of emotion and desire regulation. Simulations have been performed to illustrate the effect of the techniques. The results demonstrate the working mechanisms and feasibility of the techniques used in the model.

Dietary practices of adult Egyptians before and during the COVID-19 lockdown

Aim

The aim of this study was to describe dietary practices of adult Egyptians, estimate changes in their body mass index (BMI), and identify possible determinants of such changes before and during the COVID-19 lockdown.

Subject and methods

A cross-sectional web-based survey was conducted during the nationwide COVID-19 partial lockdown. Data were obtained from 430 Egyptian adults regarding their personal and socio-demographic characteristics, routine daily physical activities, dietary patterns, practices related to food purchase and food handling, and weight and BMI before and during the lockdown using an online web-based questionnaire.

Results

The number of daily meals and daily snacks significantly increased during the lockdown. Moreover, the consumption of all types of snacks increased, except for chocolate and sweets, whose consumption decreased. Eating of fast food decreased, whereas the number of individuals practicing indoor physical activities increased during the lockdown. During the lockdown, no significant changes in the mean BMI were observed. The mean weekly consumption of starch, meat, milk, fat, and free foods decreased, whereas the mean weekly consumption of fruits and vegetables increased. Food handling practices improved during the lockdown. Based on the results of the linear regression analysis, age, the number of daily meals, practicing of physical activities during lockdown, and mean weekly consumption of meat were the independent predictors of BMI during the lockdown.

Conclusion

During the lockdown, no significant changes in the BMI of adult Egyptians were observed, whereas dietary practices and food handling practices changed.

The Perceived Impact of COVID-19 on Comfort Food Consumption over Time: The Mediational Role of Emotional Distress

The COVID-19 pandemic has had a significant impact on populations at an economic, health, and on an interpersonal level, it is still unclear how it has affected health-risk behaviors, such as comfort food consumption over time. This study longitudinally examines the effect of the perceived impact of COVID-19 on comfort food consumption and whether this effect is mediated by emotional distress. A convenience sample of 1048 students and university staff (academic and non-academic) from two universities completed monthly online surveys during the COVID-19 pandemic across six waves (W; W1 to W6). Participants reported their perceived impact of COVID-19 (economic, interpersonal, and health), comfort food consumption, and emotional distress (DASS-21). Using structural equation models, we found an indirect longitudinal effect of the perceived impact of COVID-19 (W1) on comfort food consumption (W3 to W6) through increased emotional distress (W2). The perceived negative impact of COVID-19 on comfort food consumption was fully mediated by the emotional distress during the first waves (W3 and W4), ending in a partial mediation in the last waves (W5 and W6). These findings contribute to disentangling the mechanisms by which the perceived impact of COVID-19 affects comfort food consumption over time, and highlight the role of emotional distress. Future interventions should address comfort food consumption by focusing on handling emotional distress during a crisis.

A Comparison of Associations Between Self-Reported and Device-Based Sedentary Behavior and Obesity Markers in Adults: A Multi-National Cross-Sectional Study

The purpose of this study was to examine the associations between self-reported and device-based measures of sedentary behavior (SB) with obesity markers in adults from Latin American countries. Sitting time and total time spent in different SBs were self-reported using two different questionnaires. Accelerometers were used to assess total sedentary time. Body mass index, waist, and neck circumferences were assessed. The highest self-reported sitting time was in Argentina, the highest total time spent in different SBs was in Brazil and Costa Rica, and the highest device-based sedentary time was observed in Peru. Neither self-reported sitting time, total time spent in different SBs or device-based sedentary time were associated with body mass index. Device-based sedentary time was positively associated with waist circumference and self-reported sitting time was positively associated with neck circumference. Caution is warranted when comparing the associations of self-reported and device-based assessments of SB with anthropometric variables.

Stress and eating behaviours in healthy adults: a systematic review and meta-analysis

Stress leads to detrimental health outcomes through direct biological and indirect behavioural changes. Stress can lead to disruption to normal eating behaviours, although the strength of these associations is unknown. This is the first meta-analysis to determine the strength of the stress-eating relationship in healthy adults and to explore the impact of potential moderators. Studies included had a clearly defined measure of stress (i.e., any noxious event or episode in one's environment with the exclusion of emotional distress) that was linked to non-disordered eating. Key terms were searched in Medline, PsycInfo and Ovid databases (23,104 studies identified). 54 studies (combined N = 119,820) were retained in the meta-analysis. A small, positive effect size was found for the stress-overall food intake relationship (Hedges' g = 0.114). Stress was associated with increased consumption of unhealthy foods (Hedges' g = 0.116) but decreased consumption of healthy foods (Hedges' g = -0.111). Only one significant moderator (restraint on stress-unhealthy eating) was identified. This meta-analysis identified the magnitude of the effect of stress on eating behaviour outcomes. Significant heterogeneity was observed that was not explained by the moderators examined. Further research on moderators of the stress-eating relationship is required and should distinguish effects for healthy versus unhealthy eating.

Emotional eating across different eating disorders and the role of body mass, restriction, and binge eating

OBJECTIVE

Different subtypes of eating disorders (ED) show dysfunctional eating behaviors such as overeating and/or restriction in response to emotions. Yet, systematic comparisons of all major EDs on emotional eating patterns are lacking. Furthermore, emotional eating correlates with body mass index (BMI), which also differs between EDs and thus confounds this comparison.

METHOD

Interview-diagnosed female ED patients (n = 204) with restrictive (AN-R) or binge-purge anorexia nervosa (AN-BP), bulimia nervosa (BN), or binge-eating disorder (BED) completed a questionnaire assessing "negative emotional eating" (sadness, anger, anxiety) and "happiness eating." ED groups were compared to BMI-matched healthy controls (HCs; n = 172 ranging from underweight to obesity) to exclude BMI as a confound.

RESULTS

Within HCs, higher BMI was associated with higher negative emotional eating and lower happiness eating. AN-R reported the lowest degree of negative emotional eating relative to other EDs and BMI-matched HCs, and the highest degree of happiness eating relative to other EDs. The BN and BED groups showed higher negative emotional eating compared to BMI-matched HCs. Patients with AN-BP occupied an intermediate position between AN-R and BN/BED and reported less happiness eating compared to BMI-matched HCs.

DISCUSSION

Negative emotional and happiness eating patterns differ across EDs. BMI-independent emotional eating patterns distinguish ED subgroups and might be related to the occurrence of binge eating versus restriction. Hence, different types of emotional eating can represent fruitful targets for tailored psychotherapeutic interventions. While BN and BED might be treated with similar approaches, AN-BP and AN-R would need specific treatment modules.

Emotion-related constructs engaged by mindfulness-based interventions: A systematic review and meta-analysis

OBJECTIVES

Mindfulness-based interventions (MBIs) have been widely implemented to improve self-regulation behaviors, often by targeting emotion-related constructs to facilitate change. Yet the degree to which MBIs engage specific measures of emotion-related constructs has not been systematically examined.

METHODS

Using advanced meta-analytic techniques, this review examines construct and measurement engagement in trials of adults that used standardized applications of the two most established MBIs: Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT), or modified variations of these interventions that met defined criteria.

RESULTS

Seventy-two studies (N=7,378) were included (MBSR k=47, MBCT k = 21, Modified k=4). MBIs led to significant improvement in emotion-related processing overall, compared to inactive controls (d=0.58; k =36), and in all constructs assessed: depression (d=0.66; k=26), anxiety (d =0.63; k=19), combined mental health (d =0.75; k=7 ) and stress (d =0.44; k=11). Reactions to pain, mood states, emotion regulation, and biological measures lacked sufficient data for analysis. MBIs did not outperform active controls in any analyses. Measurement tool and population-type did not moderate results, but MBI-type did, in that MBCT showed stronger effects than MBSR, although these effects were driven by a small number of studies.

CONCLUSIONS

This review is the first to examine the full scope of emotion-related measures relevant to self-regulation, to determine which measures are most influenced by MBCT/MBSR. Compared to extant reviews, which typically focused on MBI outcomes, this work examined mechanistic processes based on measurement domains and tools. While effect sizes were similar among measurement tools, this review also includes a descriptive evaluation of measures and points of caution, providing guidance to MBI researchers and clinicians for selection of emotion-related measurement tools.

Dysfunctional Patterns of Food Intake by Anxiety during Isolation by COVID-19 in Chile, Colombia and Mexico

The aim of this research was to compare food intake dysfunctional patterns score with the subjective perception of anxiety and sociodemographic characteristics of the participants in isolation by COVID-19 from Chile, Colombia, and Mexico. A cross-sectional research was carried out, with a virtual questionnaire of subjective perception of anxiety and the questionnaire of three 18-item feeding factors. 958 people of both sexes participated (F = 83%, M = 17%), mainly in the 18 to 35 age range. Dysfunctional eating patterns presented high scores in people who perceived anxiety, as well as in participants from Chile. Additionally, it was found that women present greater cognitive restriction and emotional intake, and college students showed greater disinhibition. In conclusion, the scores of the three dysfunctional eating patterns were higher in people with subjective perception of anxiety during social isolation due to COVID-19, and there were also differences according to country, sex, and educational level.
