The effectiveness of the TRACE online nutrition intervention in improving dietary intake, sleep quality and physical activity levels for Australian adults with food addiction: a randomised controlled trial.

BACKGROUND: Few interventions for food addiction (FA) report on dietary intake variables. The present study comprised a three-arm randomised controlled trial in adults with symptoms of FA. The aim was to evaluate dietary intake, sleep and physical activity resulting from a dietitian-led telehealth intervention at 3 months. METHODS: Adults with ≥3 symptoms of FA and a body mass index > 18.5 kg/m2 were recruited. Dietary intake including energy, nutrients and diet quality were assessed by a validated food frequency questionnaire in addition to sleep quality and physical activity (total min) and compared between groups and over time. Personalised dietary goals set by participants were examined to determine whether improvements in percent energy from core and non-core foods were reported. RESULTS: The active intervention group was superior compared to the passive intervention and control groups for improvements in percent energy from core (6.4%/day [95% confidence interval (CI) -0.0 to 12.9], p = 0.049), non-core foods (-6.4%/day [95% CI -12.9 to 0.0], p = 0.049), sweetened drinks (-1.7%/day [95% CI -2.9 to -0.4], p = 0.013), takeaway foods (-2.3%/day [95% CI -4.5 to -0.1], p = 0.045) and sodium (-478 mg/day [95% CI -765 to -191 mg], p = 0.001). CONCLUSIONS: A dietitian-led telehealth intervention for Australian adults with FA found significant improvements in dietary intake variables. Setting personalised goals around nutrition and eating behaviours was beneficial for lifestyle change.

Validation of the Brazilian version of the Short Inventory of Grazing (SIG)

Abstract Objective Grazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of the SIG have not been assessed in the Brazilian population. The present study aimed to cross-culturally adapt and validate a Brazilian version of the SIG. Methods The SIG was adapted to the Brazilian context following international guidelines. Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and a question related to self-reported health status. The internal consistency, test-retest reliability, and convergent validity of the questionnaire were assessed. Results The prevalence rates of at least one weekly episode of grazing in general and LOC grazing were 71.1 and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significantly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health. However, SIG test and retest scores differed significantly. Conclusion Overall, the Brazilian version of the SIG demonstrated adequate psychometric properties. The instrument had adequate internal consistency, with both items exhibiting good convergent validity with related measures.

Is binge eating associated with poor weight loss outcomes in people with a high body weight? A systematic review with meta-analyses.

OBJECTIVES: This systematic review aimed to compare the weight change in people with or without binge eating who underwent various weight loss treatments. METHODS: We searched for studies in PubMed, American Psychological Association, and Embase from inception to January 2022. The studies selected included assessment of binge eating and body weight before and after weight loss treatment in people of any age. The meta-analyses were conducted using Comprehensive Meta-Analysis (CMA). We used Egger's regression test, the funnel plot, and the Trim and Fill test to assess the risk of publication bias. RESULTS: Thirty-four studies were included in the systematic review, with a total of 10.184 participants. The included studies were divided into three categories according to types of weight loss treatments, namely, (1) bariatric surgery; (2) pharmacotherapy isolated or combined with behavioral interventions; and (3) behavioral and/or nutritional interventions. The meta-analyses showed no significant difference in weight loss between people with or without binge eating engaged in weight loss treatments, with an overall effect size of - 0.117 (95% CI - 0.405 to 0.171; P = 0.426). CONCLUSIONS: Our findings showed no difference in weight loss in people with or without pre-treatment binge eating who received various weight loss treatments. Weight loss treatments should not be withheld on the basis that they will not be effective in people with pre-treatment binge eating, albeit their safety and longer term impacts are unclear. LEVEL OF EVIDENCE: Level I, at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies.

How to address physical activity and exercise during treatment from eating disorders: a scoping review.

PURPOSE OF REVIEW: This scoping review aimed to provide a recent update on how to address dysfunctional physical activity and exercise (DEx), and on effects and experiences from including supervised and adapted physical activity or exercise (PAE), during treatment of eating disorders. RECENT FINDINGS: A systematic search for peer-reviewed publications in the period 2021-2023 generated 10 original studies and 6 reviews, including one meta-analysis (reporting according to PRISMA and SWiM). Findings showed that DEx was effectively managed by use of psychoeducation and/or PAE. Inclusion of PAE as part of treatment showed low-to-moderate impact on health and positive or neutral effects on eating disorder psychopathology. There were no reports of adverse events. For individuals with anorexia nervosa, PAE improved physical fitness with no influence on body weight or body composition unless progressive resistance training was conducted. For individuals with bulimia nervosa, DEx was reduced simultaneously with increased functional exercise and successful implementation of physical activity recommendations during treatment. Experiences by individuals with eating disorders and clinicians, including accredited exercise physiologists, pointed to positive benefits by including PAE in treatment. SUMMARY: Lack of consensus about DEx and of recommendations for PAE in official treatment guidelines hinder adequate approaches to these issues in eating disorder treatment.

Grazing Is Associated with ADHD Symptoms, Substance Use, and Impulsivity in a Representative Sample of a Large Metropolitan Area in Brazil.

Grazing is a clinically relevant eating behaviour, especially when it presents with a sense of loss of control (compulsive grazing). There is evidence that other disordered eating patterns are associated with problematic substance use and impulsivity-related conditions, such as attention-deficit/hyperactivity disorder (ADHD). This overlap contributes to higher psychopathology and treatment complications. Less is known about grazing, and most information originates in high-income countries. Hence, we sought to investigate relationships between grazing, tobacco and alcohol use, ADHD, and impulsivity in a large representative sample from Brazil. Data were collected by trained interviewers from adults (N = 2297) through an in-person household survey based on a stratified and clustered probability sample. We found significant associations between compulsive grazing and problematic alcohol use (OR = 3.02, 95% CI: 1.65, 5.53), ADHD (OR = 8.94, 95% CI: 5.11, 15.63), and smoking (OR = 1.67, 95% CI: 1.12, 2.47), with impulsivity contributing to the first two relationships. The substantial association with ADHD suggests that other executive functions may promote disordered eating, possibly expressed through difficulties in adhering to regular meals. Clinically, these findings highlight the importance of assessing problematic eating patterns, such as compulsive grazing, in those presenting with difficulties with substance use or impulsivity, and vice versa.

Current approaches in the recognition and management of eating disorders.

Eating disorders are now well acknowledged mental health problems that are common and present in people from diverse sociodemographic backgrounds. The past decade has seen a rapid expansion in research into eating disorder interventions. In response to the increasing burden of eating disorders, the Australian Government Department of Health and Aged Care has implemented significant policy changes to improve patient access to Medicare and inpatient treatment facilities. There are several international clinical practice guidelines and a robust evidence base particularly for first line care with specific psychological therapies, including guidelines for the management of eating disorders in individuals with a high weight. Medications play an important adjunct role in care, and novel neuromodulating treatments, such as psychostimulants, are under study. There is emerging evidence for increased person-centred care, with more choice in the form of alternatives to hospital inpatient programs and more respectful consideration of care for all who experience an eating disorder, including people with high weight.

Sociocultural Influences Contribute to Overeating and Unhealthy Eating: Creating and Maintaining an Obesogenic Social Environment in Indigenous Communities in Urban Fiji.

Pacific Island countries (PICs), such as Fiji, lead the world statistics in obesity and deaths caused by non-communicable diseases. The impacts of obesity overburden the healthcare system and social services and have major impacts on the Fijian economy. This study is the first of its kind to undertake an in-depth exploration of the determinants of the obesity epidemic in PICs by exploring the sociocultural influences and situations that impact nutrient transitions, overconsumption, and unhealthy eating in an urban indigenous community. In-depth qualitative interviews were conducted with 15 indigenous Fijian women from the largest urban center in Fiji who self-identified as gatekeepers of family meal planning, preparing, and shopping for groceries, fruits, and vegetables. The women identified several cultural norms and expectations of both the individuals providing the food and the individuals consuming the food that create and maintain an obesogenic social environment. Moreover, participants also shared a misplaced value on meat, energy-dense foods, junk food, and fast foods that further contribute to unhealthy eating and overeating within this urban indigenous community. These novel findings highlight the importance of considering sociocultural influences on unhealthy eating and overeating and may be used to assist decision-makers in developing contextualized obesity prevention strategies and health messaging to target obesity in this community.

Beyond screening in primary practice settings: Time to stop fiddling while Rome is burning.

OBJECTIVE: This forum presents the current state of research in the screening and identification of people with eating disorders in community and primary care, taking a longer-term perspective that highlights the slow rate of progression in development of instruments, and impact on polices and practice. METHOD: An historical overview is presented, followed by a critique of contemporary instruments and practice, and barriers to case detection and appropriate referral pathways. RESULTS: There are now many instruments but all lack high levels of positive predictive power. However, some do have high sensitivity. Barriers contributing to poor detection and the treatment gap include need for improved education and support for primary care professionals and lack of confidence of individuals with eating disorders to initiate a discussion with health professionals. The best screening instrument would not overcome either of these barriers. DISCUSSION: We purport there is an urgent need to improve current screening instruments (not to develop more), particularly those with high sensitivity. These should be being employed alongside programs to both improve primary care professionals' skills in assessment and management of people with eating disorders, and to empower consumers to navigate care pathways. PUBLIC SIGNIFICANCE STATEMENT: We argue that further screening instruments for eating disorders are not needed. Rather, it is more urgent to have a greater research focus on how to encourage primary care workers to ask about eating and body image and how to best translate that to more individuals with eating disorders being offered treatment. This work needs to be linked with tools that empower consumers to navigate care pathways.

Chew and spit (CHSP) in bariatric patients: a case series.

BACKGROUND: Studies into the disordered eating behaviour of chew and spit have alluded to several cohorts more likely to engage in the behaviour, one such group being bariatric surgery candidates and patients. Weight-loss surgery candidates have received little to no attention regarding engaging in chew and spit behaviour. Changes in pre- and post- surgery eating pathology related to chew and spit behaviour has yet to be explored and described in academic literature. CASE PRESENTATION: The current study reports on three cases of individual women, aged 30, 35, and 62 respectively, who indicated engagement in chew and spit. All three cases underwent bariatric surgery (two underwent gastric bypass, one underwent vertical sleeve gastrectomy). Eating pathology-including chew and spit behaviour, anxiety and depression, and adherence to the Norwegian nutritional guidelines were examined pre-operatively and post-operatively (one and two-year follow-up). At baseline (pre-surgery), two participants reported that they engaged in chew and spit, compared to one patient post-surgery. All three cases reported that they, to at least some extent, adhered to dietary guidelines post-surgery. Subjective bingeing frequency appeared to be relatively low for all three cases, further declining in frequency at one-year follow-up. At baseline, one participant reported clinically significant depression and anxiety, with no clinically significant depression or anxiety reported at follow-ups in participants that chew and spit. CONCLUSIONS: The current study provides a starting point for the exploration of chew and spit as a pathological symptom of disordered eating in bariatric patients. It highlights the need to further explore chew and spit before and after weight-loss surgery.

Bariatric and Cosmetic Surgery in People with Eating Disorders.

Rates of eating disorders (EDs) are increasing in Australia, as are rates of bariatric and cosmetic surgery including weight-related procedures. It is known that binge eating disorder (BED) is common in bariatric surgery candidates and that people with EDs are likely to undergo weight-related cosmetic procedures, however, most of the literature is based on clinic samples and focuses on young women and BED. Aims of this study were to determine the prevalence of (1) actual or intended bariatric surgery and (2) actual or intended cosmetic surgery including weight-related procedures in people with a current ED and a lifetime history of BED or bulimia nervosa (BN), and the associations with actual or intended bariatric or cosmetic surgery and demographic features. Using a general population survey, 2977 individuals were interviewed regarding sociodemographic status, ED symptoms, mental health-related quality of life (MHRQoL) and actual or intended use of bariatric and cosmetic surgery, prevalence estimates of which were 2.0% and 1.1%, respectively. People who had planned or received either type of surgery were more likely to be (1) women and (2) have a higher BMI, (3) poorer MHRQoL and (4) a current ED, lifetime BN or BED or features of EDs (all p < 0.05). Age and household income were not significantly associated with increased use of either type of surgery. Given the potential for an ED to affect outcomes of surgery, screening and treatment for EDs should be considered in such surgical candidates.

Perceived need for treatment associated with orthorexia nervosa symptoms.

Orthorexia Nervosa is characterised by a pathological fixation on food purity and nutrition, coupled with a severely restricted diet and avoidance of food believed to be unhealthy. Little is known about the risk factors associated with the condition or if the condition should be treated in a similar way to other eating disorders or whether distinct interventions are required. This study aimed to identify (1) putative variables of the need for treatment in those with orthorexia symptomology and (2) assess whether comorbid psychological symptomologies were associated with orthorexia nervosa. An online cross-sectional self-report survey was developed and the data of 130 participants analysed using regression analyses. As predicted, individuals with higher levels of orthorexic symptomology, eating disorder symptomology and those who identified their healthy eating as problematic were significantly more likely to have a perceived need for treatment, however those who self-identified as having a current or past eating disorder were not. Orthorexic symptomatology was significantly correlated with eating disorder symptomatology, obsessive-compulsive symptoms, anxiety, and depression, however in the regression analysis, eating disorder symptomatology was the only significant variable. These findings highlight the need to consider orthorexic symptoms in people with eating disorders and that this inter-relationship and the ego-syntonicity of symptoms may reduce help-seeking.

Further development of the 12-item EDE-QS: identifying a cut-off for screening purposes.

BACKGROUND: The Eating Disorder Examination - Questionnaire Short (EDE-QS) was developed as a 12-item version of the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eating disorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initial testing. The purpose of this brief report is to determine a threshold score that could be used in screening for probable ED cases in community settings. METHODS: Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female; 9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA). Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curve analyses. RESULTS: A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) and specificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable to other ED instruments. CONCLUSION: The EDE-QS appears to be an instrument with good discriminatory power that could be used for ED screening purposes.

Accuracy of self-reported physical activity in patients with anorexia nervosa: links with clinical features.

BACKGROUND: High levels of physical activity (PA) have long been described in patients with Anorexia Nervosa (AN). Despite the importance of measuring PA in this population, there are two important factors that remain unknown. First, it is not clear how accurate self-report measures of PA are among patients. Second, little is known about how clinical characteristics are associated with the accuracy of self-reported PA. Therefore, this study aimed to examine the accuracy of self-reported PA compared to an objective measure of PA in patients with AN. It also investigated whether levels of accuracy/inaccuracy were associated with compulsive exercise, motivation to change, and psychological distress. METHOD: Data were analysed from 34 adult outpatients with AN. Patients wore an accelerometer device (ActiGraph) for 4 days and completed a retrospective self-report measure of exercise (Exercise Participation Screening Questionnaire). They also completed measures of compulsive exercise (Compulsive Exercise Test), motivation to change (The Anorexia Nervosa Stages of Change Questionnaire), and psychological distress (Kessler-10). RESULTS: On the self-report measure, patients accurately reported their time spent in moderate and vigorous intensity PA, however, they significantly under-reported their light physical activity (compared to the accelerometer data). Accurate reporting of total PA was positively associated with higher levels of compulsive exercise. There was evidence to suggest that clinical features, such as motivation to change and psychological distress, may be associated with inaccurate reporting at some levels of PA intensity and not others. CONCLUSIONS: Results indicate that patients with AN are likely to under-report their light intensity PA. We also found preliminary evidence for how compulsive exercise, motivation to change, and distress are associated with self-reported PA accuracy. Clinical implications and directions for future research are considered. TRIAL REGISTRATION: ACTRN12610000585022.

Systematic review of depression and anxiety in psoriatic arthritis.

AIM: To investigate the point prevalence of depression and anxiety in psoriatic arthritis and putative reductions in these comorbidities with the treatment of psoriatic arthritis. METHOD: We performed a systematic review in accordance with PRISMA guidelines examining point prevalence of depression and anxiety in psoriatic arthritis as well as effects of treatment for psoriatic arthritis on these psychiatric comorbidities. MEDLINE, EMBASE, EBM Reviews and Cochrane, and PsycINFO were searched from inception to October 2017. Quality of studies was assessed using the Joanna Briggs Institute Checklist for Prevalence Studies. Study and population characteristics were extracted and entered into an electronic database for subsequent descriptive and meta-analysis of point prevalence. RESULT: Three studies matched inclusion criteria with significant statistical heterogeneity. The prevalence of depression ranged between 9%-22% and anxiety between 15%-30% in patients with psoriatic arthritis. One study matched inclusion criteria for treatment effect analysis, albeit with a high risk of bias and illustrated a benefit of etanercept on the prevalence of depression (9% vs 16%) and anxiety (14% vs 30%) after 24 weeks of treatment. CONCLUSION: This is the first systematic review of point prevalence of depression and anxiety in patients with psoriatic arthritis. There is a moderate point prevalence of both depression and anxiety in patients with psoriatic arthritis, which is similar or slightly higher than the general population and comparable to that seen in other rheumatic diseases. The effects of treatment for psoriatic arthritis on comorbid depression and anxiety remain unclear.

Bullying and sexual abuse and their association with harmful behaviours, antidepressant use and health-related quality of life in adulthood: a population-based study in South Australia.

BACKGROUND: Few representative sample studies have reported estimates of bullying and sexual abuse in Australia. By using face-to-face interviews and self-labelling questions, we investigated the prevalence of these forms of abuse and their relationship with current harmful behaviours (smoking dependence, excessive alcohol intake, binge eating), antidepressant use, and the physical (PCS) and mental (MCS) components of health-related quality of life. METHODS: This study was a population-based survey that investigated 2873 South Australians in 2015 (48.8 ± 18.1 years; 49.3% males). Bullying and sexual abuse (age of onset and duration) and their outcomes were investigated through household interviews. Associations were adjusted for sociodemographic variables by using regression models. RESULTS: 45.6% (95% CI 43.3-47.9) of the participants were bullied, and 10.4% (95% CI 9.1-11.9) sexually abused; 7.3% (95% CI 6.2-8.5) reported experiencing both forms of abuse. Moreover, 15.8% of those bullied and 15.0% of those sexually abused suffered from these forms of abuse for > 24 months. Smoking dependence (7.8%) was twice as frequent among those who experienced bullying for > 24 months or when sexual abuse occurred in childhood (< 10 years) or adulthood (20+ years) or lasted ≥1 month. Excessive alcohol intake (14.3%) was more frequent when bullying occurred in childhood or lasted > 24 months. Binge eating (8.1%) was more frequent among those bullied or sexually abused in adulthood, but duration did not show a clear pattern. Antidepressant use was up to four times more likely, and PCS or MCS lower among those who were bullied or sexually abused, independent of when these forms of abuse started or their duration. The cumulative adverse relationship of bullying and sexual abuse with the investigated outcomes was more evident for smoking dependence, binge eating, PCS, and MCS than for antidepressant use, but no association was observed with alcohol intake. CONCLUSIONS: The use of self-labelling questions to investigate sensitive areas such as bullying and sexual abuse in a survey is feasible. Such questions provided estimates that are consistent with findings from studies using more detailed instruments. Bullying and sexual abuse have an additive adverse association with various outcomes. Identifying survivors of both forms of abuse is important to avoid more serious consequences.

Grazing in adults with obesity and eating disorders: A systematic review of associated clinical features and meta-analysis of prevalence.

Grazing, the unstructured, repetitive eating of small amounts of food, is a pattern of eating which has been associated with negative outcomes following bariatric surgery. Less is known about grazing in eating disorders and in non-surgical obese samples. This review aims to critically examine the existing research on the prevalence of grazing, associated treatment outcomes, and clinical correlates in adults with eating disorders and/or obesity, in clinical and community settings. A systematic electronic database search yielded 38 studies which met inclusion criteria for the review. A meta-analysis was conducted using prevalence data from 32 studies (31 datasets). Mean pooled prevalence in obesity (n=26 studies) was 33.20% (95% CI [27.54, 39.11]) at pre-weight loss treatment, 28.16% (95% CI [17.86, 39.73]) at follow-up, and 23.32% (95% CI [3.07, 52.04]) in the community. Nine studies provided prevalence estimates in eating disorders: 58.25% (95% CI [52.75, 63.66]) in bulimia nervosa; 67.77% (95% CI [44.96, 87.13]) in binge eating disorder; and 34.31% (95% CI [26.56, 42.49]) in anorexia nervosa. The results suggest that grazing is widely prevalent within obesity and eating disorders. There is mixed evidence to suggest that grazing (especially a "compulsive" subtype including a sense of loss of control) is associated with poorer weight loss treatment outcomes in obesity, lower mood, increased eating disorder symptomatology, and decreased mental health-related quality of life. Differences in the operationalisation of grazing may account for inconsistent findings in regards to specific correlates and risks associated with this behaviour; therefore, there is an urgent need to refine and adopt a consistent definition of grazing.
