No control and overwhelming cravings: Australian adults' perspectives on the experience of food addiction

Exploring Psychological Constructs in People Receiving Treatment for Addictive Eating Behaviours: "I Hate Loving Food as Much as I Do"

Research into the complexities of addictive eating behaviours continues to develop, as a deeper understanding of this construct beyond self-report diagnostic tools emerges. In this study, we undertook structured interviews with 40 participants engaged in a personality-based management program for addictive eating, to gain insight into what situations lead people with addictive eating behaviours to overeat, and how they believe their lives would be different if they had control over their eating. A phenomenological analysis to explore compulsion and control in the context of food experiences for participants was used to construct two main themes of the addictive eating paradox and striving to transition from 'other' to 'normal'. The addictive eating paradox identified multiple contradictory experiences of a situation, e.g., 'loving food' but 'hating food'. Striving to transition from 'other' to 'normal' encompassed the idea that participants envisaged that by gaining control over their eating they could become 'normal'. This study emphasises the need to provide support and strategies to help people navigate paradoxical thoughts and presents new ideas to increase the effectiveness of interventions for individuals struggling with the complex self-beliefs held by those with addictive eating behaviours.

Evening types as determined by subjective and objective measures are more emotional eaters

OBJECTIVE

This study aimed to determine the association between being an evening type (ET; defined subjectively by the Morning-Evening Questionnaire or objectively by the dim-light melatonin onset [DLMO] timing) and reporting emotional eating (EE) behaviors.

METHODS

Cross-sectional analyses were conducted in 3964 participants (four international cohorts: ONTIME and ONTIME-MT [both Spain], SHIFT [the US], and DICACEM [Mexico]), in which chronotype (Morning-Evening Questionnaire), EE behaviors (Emotional Eating Questionnaire), and dietary habits (dietary records or food-frequency questionnaire) were assessed. Among 162 participants (ONTIME-MT subsample), additional measures of DLMO (physiological gold standard of circadian phase) were available.

RESULTS

In three populations, ETs presented with a higher EE score than morning types (p < 0.02); and they made up a higher proportion of emotional eaters (p < 0.01). ETs presented with higher scores on disinhibition/overeating as well as food craving factors and experienced these behaviors more frequently than morning types (p < 0.05). Furthermore, a meta-analysis showed that being an ET was associated with a higher EE score by 1.52 points of a total of 30 points (95% CI: 0.89-2.14). The timing of DLMO in the early, intermediate, and late objective chronotypes occurred at 21:02 h, 22:12 h, and 23:37 h, with late types showing a higher EE score (p = 0.043).

CONCLUSIONS

Eveningness associated with EE in populations with different cultural, environmental, and genetic backgrounds. Individuals with late DLMO also showed more EE.

Binge eating, depressive symptoms and suicidal ideation in obese candidates for bariatric surgery

PURPOSE

The aim of the present study was to determine possible associations between binge eating, depressive symptoms and suicidal ideation in obese candidates for bariatric surgery.

METHODS

A cross-sectional study was conducted with 254 obese patients recruited from the general surgery service for bariatric procedures at the hospital affiliated with the Federal University of Pernambuco, Brazil. Evaluations were performed using the Binge Eating Scale (BES), Beck Depression Inventory, Beck Scale for Suicidal Ideation (BSSI) and a questionnaire addressing sociodemographic characteristics.

RESULTS

Most patients were women (82%), 48% had a moderate binge eating disorder, 42% a severe binge eating disorder, 32% had symptoms suggestive of mild, moderate or severe depression and 6% had suicidal ideation. Severe binge eating was positively associated with depressive symptoms (p < 0.001) and suicidal ideation (p < 0.05). Cases of severe binge eating were more frequent in young adults, but not necessarily associated with symptoms of depression or suicidal ideation in this portion of the sample.

CONCLUSIONS

The present findings underscore the need for psychological and psychiatric follow-up of obese candidates for bariatric surgery using appropriate assessment scales to guide therapeutic approaches.

Socio-Demographic, Self-Control, Bullying, Parenting, and Sleep as Proximal Factors Associated with Food Addiction among Adolescents

Adolescence is considered an important period of neurodevelopment. It is a time for the emergence of psychosocial vulnerabilities, including symptoms of depression, eating disorders, and increased engagement in unhealthy eating behaviours. Food addiction (FA) in adolescents is an area of study where there has been substantial growth. However, to date, limited studies have considered what demographic characteristics of adolescents may predispose them to endorse greater symptoms of FA. Studies have found a variety of factors that often cluster with and may influence an adolescent's eating behaviour such as sleep, level of self-control, and parenting practices, as well as bullying. Therefore, this study investigated a range of socio-demographic, trait, mental health, and lifestyle-related profiles (including self-control, parenting, bullying, and sleep) as proximal factors associated with symptoms of FA, as assessed via the Yale Food Addiction Scale for Children (YFAS-C) in a large sample of Australian adolescents. Following data cleaning, the final analysed sample included 6587 students (age 12.9 years ± 0.39; range 10.9-14.9 years), with 50.05% identifying as male (n = 3297), 48.5% as female (n = 3195), 1.02% prefer not to say (n = 67), and 0.43% as non-binary (n = 28). Self-control was found to be the most significant predictor of total FA symptom score, followed by female gender, sleep quality, and being a victim of bullying. Universal prevention programs should therefore aim to address these factors to help reduce the prevalence or severity of FA symptoms within early adolescent populations.

Mediating effect of self-control in the relationship between psychological distress and food addiction among college students

Psychological distress is a possible trigger contributing to food addiction, which is characterized by a loss of behavioral control and compulsive food intake. However, little is known about its underlying mechanisms. Self-control, an important self-regulation skill, may mediate the effect of psychological distress on food addiction. A cross-sectional survey was used to explore the direct relationship between psychological distress and food addiction, and the mediating role of self-control in this relationship. Food addiction, psychological distress, and self-control were evaluated using the Chinese versions of the Yale Food Addiction Scale 2.0, Depression-Anxiety-Stress Scale, and Self-control Scale, respectively. Correlation analyses showed that food addiction was positively correlated with psychological distress, but negatively related to self-control. Structural equation modeling revealed the mediating role of self-control in the relationship between food addiction and psychological distress. As a significant predictor of food addiction, psychological distress may induce food addiction directly or indirectly through the effect of self-control. These findings provide a deeper understanding of the relationship between psychological distress and food addiction, and the underlying mechanism. As such, psychological distress and self-control should be included in prevention and intervention strategies to address food addiction among college students.

Food Addiction: a Deep Dive into ‘Loss of Control’ and ‘Craving’

Purpose of Review

The majority of existing research discusses food addiction (FA) classification, which provides information for different groups and which groups may or may not be affected to differing degrees. Fewer studies report FA symptom scores, and fewer still report on individual symptoms. This paper discusses the symptoms of craving and loss of control as they are common FA symptoms that demonstrate similarities with both substance use disorders and some eating disorder pathology.

Recent Findings

Loss of control presents parallels with disordered eating, particularly binge eating disorder. Craving refers to the powerful or strong desire for something and, in contrast to lack of control, presents most overlap with substance use disorders.

Summary

While not the most common symptoms reported in published research, loss of control and craving attract attention because of parallels with substance use and eating disorder pathology, and research has increasingly focused on these symptoms in recent years.

Global scientific production regarding behavioral addictions: An analysis of the literature from 1995 to 2019

•

There is an increase in behavioral addiction research over the last 25 years.

•

The most considerable increase has been in gambling and ITC related problems.

•

Western countries are more interested in gambling and Asians in ITC related problems.

Aims

The increase in scientific interest in so-called behavioral addictions has been growing in recent years. For this reason, the aim of our study is to use bibliometric techniques to identify where and with what intensity these behaviors are being studied.

Methods

In October 2020, we conducted a search in the Web of Science Core Collection using a search equation designed to retrieve the articles that combine the general keywords of addiction with specific terms of the 7 groups of behavioral addictions analyzed (gambling; gaming; information and communication related disorders; and the so-called somatic addictions related to sex, shopping, food and sports). Articles published from 1995 to 2019 were included.

Results

We found 9199 distinct articles. Gambling was the most studied addiction, but Information and Technology Communication-related disorders (ITC) had the highest growth rate over the span of five five-year periods, followed by gaming and food addiction. In general, there was a growth rate of 130.46% in the research on behavioral addiction issues. By geographical region, the United States was the most productive country regarding all addictions, but Oceania had the highest proportion of publications per million population. There was a clear interest among Asian countries in studying problems related to ITC and gaming problems.

Conclusions

The importance of the seven behavioral addictions analyzed according to their growth rate in scientific research fields over the last 25 years was confirmed in our study. In addition, the differences in interest by geographical region show us that it is important to delve deeper into cultural particularities to better understand this phenomenon.

Characteristics of individuals seeking addictive eating treatment

PURPOSE

There is increasing interest in food addiction and its potential treatment. However, little is known about the characteristics of people seeking addictive eating treatment, which is important to develop appropriate treatment and referral pathways. The aim was to describe the characteristics of individuals seeking addictive eating treatment and examine differences between eligible participants who did and did not engage in treatment.

METHODS

Participants interested in an addictive eating treatment were recruited to an online screening survey. The 55-item survey included demographic questions, body satisfaction; weight-loss attempts; the modified Yale Food Addiction Survey (mYFAS); the Binge Eating Scale and mental health outcomes (DASS-21).

RESULTS

Individuals seeking addictive eating treatment (n = 309) were predominantly female (61%), from the obese BMI category (67%) and had accessed a range of services for weight loss (97%). Using multiple logistic regression, participants with higher mYFAS scores were more likely to engage in treatment (AOR 1.68; 95% CI 1.12-2.52), while participants with higher DASS total scores were less likely to engage in treatment (AOR 0.97; 95% CI 0.95-0.99).

CONCLUSION

This study indicates considerable interest from consumers in seeking addictive eating treatment. Individuals who did not engage in treatment displayed higher mental health comorbidity, suggesting that higher mental health symptomatology may be a barrier to treatment. Future qualitative research is needed to provide an in-depth understanding of the reasons for seeking and engaging in addictive eating treatment, as well as to identify the optimal treatments and referral pathways.
