Secondary analysis of YFAS 2.0 symptom counts, impairment/distress, and food addiction severity in adults with overweight/obesity

Addiction to ultra-processed foods as a mediator between psychological stress and emotional eating during the COVID-19 pandemic

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic induced psychological distress, which is linked to emotional eating and symptoms of addiction to ultra-processed foods (UPFs).

OBJECTIVE

This study aimed to investigate whether symptoms of addiction to UPFs mediate the relationship between psychological stress due to the COVID-19 pandemic and emotional eating behaviour.

METHODS

A cross-sectional online study was conducted from May to November 2021 among 368 undergraduate Brazilian students. The participants answered demographic questions and completed validated scales, including the Coronavirus Stress Measure, Modified Yale Food Addiction Scale 2.0 and Emotional Eating Questionnaire. Mediation analysis was employed to examine the hypothesised relationships.

RESULTS

The results revealed a significant indirect effect, indicating that symptoms of food addiction mediated the association between perceived stress during the COVID-19 pandemic and emotional eating behaviour. Specifically, 61% of the influence of perceived stress on emotional eating during the pandemic was explained by symptoms of UPF addiction.

CONCLUSION

These findings suggest that addressing symptoms of UPF addiction could be pivotal in public health strategies aimed at promoting healthy eating habits among distressed undergraduate students in the post-COVID-19 era.

Validity of the Addiction-like Eating Behavior Scale among Patients with Compulsive Eating

Food addiction (FA) and binge eating disorder (BED) co-occur and share compulsive eating symptoms. When using an FA measure, it is important to evaluate its performance in a population presenting compulsive eating. The study aims to validate the Addiction-like Eating Behavior Scale (AEBS) among a clinical sample characterized by compulsive eating and overweight/obesity and to evaluate its incremental validity over the Yale Food Addiction Scale 2.0 (YFAS). Patients seeking help for compulsive eating (n = 220), between January 2020 and July 2023, completed online questionnaires, including FA, compulsive eating, and BMI evaluations. The factor structure, internal consistency, and convergent, divergent, and incremental validity were tested. The sample had a mean age of 44.4 years old (SD = 12.7) and a mean BMI of 38.2 (SD = 8.0). The two-factor structure provided a good fit for the data, with factor loadings from 0.55 to 0.82 (except for item 15) and the internal consistency was high (ω = 0.84-0.89). The AEBS was positively correlated with the YFAS (r = 0.66), binge eating (r = 0.67), grazing (r = 0.47), craving (r = 0.74), and BMI (r = 0.26), and negatively correlated with dietary restraint (r = -0.37), supporting good convergent and divergent validity. For each measure of compulsive eating, linear regression showed that the AEBS "appetite drive" subscale had a unique contribution over the YFAS. This study provided evidence that the AEBS is a valid measure among a clinical sample of patients with compulsive eating and overweight/obesity. However, questions remain as to whether the AEBS is a measure of FA or compulsive eating.

A three-arm randomised controlled trial of a telehealth intervention targeting improvement in addictive eating for Australian adults (the TRACE program)

There is a substantial research base for addictive eating with development of interventions. The current 3-arm RCT aimed to investigate the efficacy of the TRACE (Targeted Research for Addictive and Compulsive Eating) program to decrease addictive eating symptoms and improve mental health. Participants (18-85 yrs) endorsing ≥3 addictive eating symptoms were randomly allocated to 1) active intervention, 2) passive intervention, or 3) control group. Primary outcome was change in addictive eating symptoms 3-months post-baseline measured by the Yale Food Addiction Scale. Depression, anxiety and stress were also assessed. A total of 175 individuals were randomised. Using Linear Mixed Models, from baseline to 3-months, there was significant improvement in symptom scores in all groups with mean decrease of 4.7 (95% CI: -5.8, -3.6; p < 0.001), 3.8 (95% CI: -5.2, -2.4; p < 0.001) and 1.5 (95% CI: -2.6, -0.4; p = 0.01) respectively. Compared with the control group, participants in the active intervention were five times more likely to achieve a clinically significant change in symptom scores. There was a significant reduction in depression scores in the active and passive intervention groups, but not control group [-2.9 (95% CI: -4.5, -1.3); -2.3 (95% CI: -4.3, -0.3); 0.5 (95% CI: -1.1, 2.1), respectively]; a significant reduction in stress scores within the active group, but not passive intervention or control groups [-1.3 (95% CI: -2.2, -0.5); -1.0 (95% CI: -2.1, 0.1); 0.4 (95% CI: -0.5, 1.2), respectively]; and the reduction in anxiety scores over time was similar for all groups. A dietitian-led telehealth intervention for addictive eating in adults was more effective than a passive or control condition in reducing addictive eating scores from baseline to 6 months.

Are healthiness and pleasure dimensions perceived similarly by people with food addiction in Brazil? A case study using holistic sensory methodologies

The relationship between the consumption of hyper-palatable ultra-processed foods and the process of addiction gains notoriety due to its relationship with obesity. Food addiction is a complex phenomenon intrinsically related to the individual's behavioral, emotional, and subjective aspects. Therefore, using classical approaches to sensory science may be insufficient to understand better the individual's sensory experience with hyper-palatable foods. In this context, sensory and consumer science techniques with holistic approaches have been aimed at accessing more subjective consumer perceptions. This study used the Yale Food Addiction Scale (YFAS 2.0) to investigate the prevalence of food addiction and the Structured Projective Mapping (S-MP) and Sorting techniques to verify how individuals with and without food addiction perceive and understand different types of food. The prevalence of food addiction was 21.77% (n = 59 out of 271) and was associated with a higher BMI but not with sociodemographic aspects. Projective Mapping (RV = 0.937) and Sorting (RV = 0.934) indicated that perception in relation to attributes such as health and pleasure was similar for all investigated foods in individuals with or without food addiction. The presence of addictive eating behavior does not seem to be related to the way individuals perceive foods from different categories, for example, minimally or highly processed and hyper-palatable foods.

Modified Mediterranean-Ketogenic Diet and Carboxytherapy as Personalized Therapeutic Strategies in Lipedema: A Pilot Study

In recent years, the use of the ketogenic diet as a proper nutritional treatment for lipedema has been hypothesized in the literature. This is the first clinical study evaluating the ketogenic diet and carboxytherapy in lipedema patients. In the present study, it was decided to use a modified Mediterranean ketogenic diet (MMKD) in combination with carboxytherapy. Since lipedema is characterized by microangiopathy, local hypoxia, and increased subcutaneous adipose tissue (SAT) deposition, carboxytherapy could improve painful symptoms and skin tone. A total of 22 subjects were included in the data analysis, divided into three groups; 8 patients underwent MMKD combined with carboxytherapy sessions (KDCB group), 8 underwent MMKD nutritional treatment alone (KD group), and 6 patients underwent only carboxytherapy sessions (CB group), for a total of 10 weeks of treatment for all three groups. It was observed that the ketogenic diet effectively induced weight and fat mass loss, including in the limbs, areas considered unresponsive to diet therapy in lipedema patients. However, the best results were obtained from the combination of the ketogenic diet and carboxytherapy, which showed improvements in both body composition and skin texture and a reduction in pain, along with an improvement in sleep quality. It would be helpful to conduct a clinical trial on a larger scale and over a more extended period to observe the results in the long term as well.

Group therapy to reduce maladaptive eating behaviors in people with overweight or obesity: Does food addiction impact the treatment response?

BACKGROUND

Given that the presence of food addiction worsens the clinical portrait in people with overweight or obesity, it could also impact the treatment response. The objective was to explore the moderating effect of baseline food addiction (FA) on the treatment response. The associations between changes in FA symptoms and other maladaptive eating behaviors were also examined.

METHODS

Sixty adults with overweight or obesity were recruited and took part in a 12-session group therapy for compulsive eating. They completed questionnaires on FA and three treatment outcomes (binge eating, grazing, and depressive symptoms). Participants were split into two groups according to their number of baseline FA symptoms (no/mild FA vs. moderate/severe FA) and were compared on all outcomes at four measurement points (baseline, mid-treatment, post-treatment, and 6-month follow-up). Correlations between changes in FA symptoms and all three outcomes from pre- to post-treatment were performed.

RESULTS

Group and treatment effects were significant for binge eating and grazing but not for depressive symptoms. Interaction effects were not significant for the three outcomes. The reduction in FA symptoms from pre- to post-treatment was positively associated with the reduction in binge eating (r = 0.49) and grazing (r = 0.55).

CONCLUSIONS

People with moderate/severe FA maintained higher maladaptive eating behaviors than people with no/mild FA from the beginning to the end of the treatment. Progression through treatment followed the same pattern for both groups, suggesting that baseline FA did not have a moderating effect. People with moderate/severe FA would likely benefit from a longer treatment.

Childhood sexual abuse and food addiction severity in a clinical sample of individuals with overweight or obesity

PURPOSE

A higher risk of food addiction (FA) in individuals reporting childhood sexual abuse (CSA) has been well demonstrated with community samples, but studies including clinical samples failed to replicate this relation. This study examined, among individuals presenting eating and weight disorders, the risk of FA for those reporting CSA while considering the severity of CSA and other types of traumas.

METHODS

Participants (N = 187) completed a DSM-5 diagnosis assessment and questionnaires on LimeSurvey evaluating FA, interpersonal traumas, depressive level, body esteem, dieting/weight preoccupations, and body mass index (BMI). Logistic regressions were used to calculate the odds ratio (OR) of FA using interpersonal traumas as risk factors, and t tests were used to compare individuals with FA and CSA and those with FA without CSA.

RESULTS

Of all interpersonal traumas, CSA was associated with the highest risk of FA, with ORs of 1.73 (p = 0.094) and 2.07 (p = 0.034). The relationship with the abuser, the type of sexual abuse and the number of abuses were significant or marginally significant risk factors, with ORs ranging from 1.26 to 1.50. Finally, no significant difference was found between FA with CSA and FA without CSA.

CONCLUSION

Using a clinical sample, this study showed a higher risk of FA in individuals reporting CSA and provided evidence that the relationship with the abuser, the type of sexual abuse, and the number of abuses are relevant factors. Additionally, in individuals with FA, the presence or absence of CSA did not influence depressive level, body esteem, dieting/weight preoccupations, or BMI.

Examining impairment and distress from food addiction across demographic and weight groups

Rates of food addiction (FA) vary across weight and demographic groups. Factors influencing discrepant prevalence rates are largely unknown. Rates of clinically significant distress or impairment also vary across demographic groups, yet prior studies have overlooked the diagnostic significance of distress/impairment in heterogenous groups. We tested if weight and demographic groups differed in their likelihood of endorsing distress/impairment from FA. Participants (N = 1832) recruited from Amazon Mechanical Turk completed the modified Yale Food Addiction Scale 2.0 (mYFAS). The mYFAS includes 11 dichotomous symptom indicators and one dichotomous distress/impairment indicator. Differences in distress/impairment were tested across weight, sex, racial/ethnic, and educational groups using logistic regression. FA severity was controlled for using FA symptom count. There were no differences among racial/ethnic and educational groups (p > 0.05). Compared to men, women were more likely to report distress/impairment (aOR = 1.96, 95% CI = 1.28-3.03). People with obesity were more likely to report distress/impairment compared to people with overweight (aOR = 2.20, 95% CI = 1.39-3.49) or normal weight (aOR = 1.99, 95% CI = 1.26-3.13). Individual characteristics (i.e., sex, weight) may influence reporting of distress/impairment from FA. Further inquiry may be appropriate for men and people with normal weight or overweight presenting with FA symptoms who otherwise deny distress/impairment.
