RESUMO
Substantial progress has been made in the understanding of anorexia nervosa (AN) and eating disorder (ED) genetics through the efforts of large-scale collaborative consortia, yielding the first genome-wide significant loci, AN-associated genes, and insights into metabo-psychiatric underpinnings of the disorders. However, the translatability, generalizability, and reach of these insights are hampered by an overly narrow focus in our research. In particular, stereotypes, myths, assumptions and misconceptions have resulted in incomplete or incorrect understandings of ED presentations and trajectories, and exclusion of certain patient groups from our studies. In this review, we aim to counteract these historical imbalances. Taking as our starting point the Academy for Eating Disorders (AED) Truth #5 "Eating disorders affect people of all genders, ages, races, ethnicities, body shapes and weights, sexual orientations, and socioeconomic statuses", we discuss what we do and do not know about the genetic underpinnings of EDs among people in each of these groups, and suggest strategies to design more inclusive studies. In the second half of our review, we outline broad strategic goals whereby ED researchers can expand the diversity, insights, and clinical translatability of their studies.

We present innovative research practices in psychiatric genetic studies to ensure representation of individuals from diverse ancestry, sex assigned at birth, gender identity, age, body shape and size, and socioeconomic backgrounds. Due to histories of inappropriate and harmful practices against marginalized groups in both psychiatry and genetics, people of certain identities may be hesitant to participate in research studies. Yet their participation is essential to ensure diverse representation, as it is incorrect to assume that the same genetic and environmental factors influence the risk for various psychiatric disorders across all demographic groups. We present approaches developed as part of the Eating Disorders Genetics Initiative (EDGI), a study that required tailored approaches to recruit diverse populations across many countries. Considerations include research priorities and design, recruitment and study branding, transparency, and community investment and ownership. Ensuring representation in participants is costly and funders need to provide adequate support to achieve diversity in recruitment in prime awards, not just as supplemental afterthoughts. The need for diverse samples in genetic studies is critical to minimize the risk of perpetuating health disparities in psychiatry and other health research. Although the EDGI strategies were designed specifically to attract and enroll individuals with eating disorders, our approach is broadly applicable across psychiatry and other fields.

AIM: To summarize the associations between weight stigma and physiological and psychological health for individuals who are overweight or obese. BACKGROUND: Weight stigma can be defined as individuals experiencing verbal or physical abuse secondary to being overweight or obese. Weight stigma has negative consequences for both physiological and psychological health. DESIGN: A quantitative systematic review. DATA SOURCES: PubMed, PsycINFO, CINAHL and MEDLINE from 1 January 2008 - 30 July 2016. REVIEW METHODS: A systematic review was conducted using the Cochrane Collaboration guidelines, the PRISMA statement guidelines and the quality assessment from the National Heart, Lung and Blood Institute. Inclusion criteria consisted of quantitative studies that examined the associations between weight stigma and physiological and psychological health outcomes in adults who were overweight or obese. Exclusion criteria consisted of qualitative studies, literature reviews, expert opinions, editorials and reports on weight stigma without health outcomes or with behavioural outcomes and intervention studies that reduced weight stigma. A quality appraisal of the selected studies was conducted. RESULTS: A total of 33 studies met the eligibility criteria. Weight stigma was positively associated with obesity, diabetes risk, cortisol level, oxidative stress level, C-reactive protein level, eating disturbances, depression, anxiety, body image dissatisfaction and negatively associated with self-esteem among overweight and obese adults. CONCLUSION: Weight stigma is associated with adverse physiological and psychological outcomes. This conclusion highlights the need to increase public and professional awareness about the issue of weight stigma and the importance of the further development of assessment and prevention strategies of weight stigma.

Law enforcement is a stressful occupation that places significant psychological demands on those serving in this role. However, little is known about the severity of work-related stress and psychological distress among law enforcement officers (LEOs) in North Carolina (NC). This cross-sectional study examined the severity of work-related stress and psychological distress among 283 LEOs in NC. The Maslach Burnout Inventory, the Operational Police Stress Questionnaire, the Depression, Anxiety, and Stress Scale, and the Post-Traumatic Stress Disorder (PTSD) Checklist were used to assess burnout, operational police stress, depression, anxiety, stress, and PTSD among LEOs. Descriptive statistics, independent t-tests, Mann-Whitney U tests, one-way ANOVA, and Kruskal-Wallis tests were performed. Rural and male LEOs reported higher burnout levels related to depersonalization (i.e., increased mental distance from one's job) compared with their urban and female counterparts. LEOs exposed to toxic materials or performing patrol duties exhibited higher operational police stress levels than those who did not. Caucasian LEOs exhibited higher depression, anxiety, and stress than their African American counterparts. Rural LEOs and LEOs who were exposed to toxic materials displayed higher levels of PTSD than their counterparts. Our findings highlight the need for increased mental health support and better working environments for LEOs.
RESUMO
There is an association between emotional eating and cardiovascular disease (CVD) risk factors; however, little is known about this association in the police force. This study explores the associations between emotional eating and CVD risk factors in law enforcement officers in North Carolina. Four hundred and five officers completed The Emotional Eating Scale, and 221 of them completed the assessment for CVD-related markers. Descriptive statistics, Pearson's correlation, and multiple linear regression analyses were performed. Emotional eating in response to anger was significantly positively associated with body weight (ß = 1.51, t = 2.07, p = 0.04), diastolic blood pressure (ß = 0.83, t = 2.18, p = 0.03), and mean arterial pressure (ß = 0.84, t = 2.19, p = 0.03) after adjusting for age and use of blood pressure medicine. Emotional eating in response to depression was significantly positively associated with triglycerides (ß = 5.28, t = 2.49, p = 0.02), while the emotional eating in response to anxiety was significantly negatively associated with triglycerides (ß = -11.42, t = -2.64, p = 0.01), after adjusting for age and use of cholesterol medicine. Our findings offer new insights to address emotional eating and lower CVD risk in law enforcement officers.

RESUMO
The pathogenesis of anorexia nervosa (AN) has been hypothesized to involve several biological systems. However, reliable biomarkers for AN have yet to be established. This study was aimed to identify statistically significant and clinically meaningful peripheral biomarkers associated with AN. A systematic literature search was conducted to identify studies published in English from inception until 30 June 2022. We conducted two-level random-effects meta-analyses to examine the difference between AN and comparison groups across 52 distinct biomarkers and found that acylated ghrelin, adrenocorticotropic hormone (ACTH), carboxy-terminal collagen crosslinks (CTX), cholesterol, cortisol, des-acyl ghrelin, ghrelin, growth hormone (GH), obestatin, and soluble leptin receptor levels were significantly higher in cases of AN compared with those in non-AN controls. Conversely, C-reactive protein (CRP), CD3 positive, CD8, creatinine, estradiol, follicle-stimulating hormone (FSH), free thyroxine, free triiodothyronine, glucose, insulin, insulin-like growth factor 1 (IGF-1), leptin, luteinizing hormone, lymphocyte, and prolactin levels were significantly lower in AN compared with those in non-AN controls. Our findings indicate that peripheral biomarkers may be linked to the pathophysiology of AN, such as processes of adaptation to starvation. Scientific investigation into peripheral biomarkers may ultimately yield breakthroughs in personalized clinical care for AN.

The purpose of this paper is to clarify the structure-activity relationship of anti-tumor activity of diosgenin derivatives in vitro. Study has found that diosgenin can inhibit the reproduction of tumor cells by inducing apoptosis and the main target spot of this effect is Bcl-2. Based on the characteristics of pharmacophoric points' of the three-dimensional pharmacophore for Bcl-2 inhibitors, we have docked lots of diosgenin derivatives with Bcl-2, then synthesized 31 compounds of them, finally assessed the anti-tumor activity of the diosgenin derivatives in vitro against A375, A549, HepG-2 and K562. Preliminary studies of SAR have indicated that the aliphatic esters, and aromatic esters of diosgenin without F ring have no anti-tumor activity in vitro. The triazole bromides of diosgenin all achieve fairly good anti-tumor activity in vitro, and those with larger hydrophobic group have the better activity. The stronger is the hydrogen bonding interaction and dipole-dipole interaction of the heterocyclic of diosgenin and diosgenin without F ring and the acid ester of diosgenin without F ring, the better is the activity of derivatives.

Obesity is often caused by an unhealthy lifestyle, which is a composite of various individual behaviors. Nurses may assist obese patients to lose weight and avoid chronic disease by identifying risky lifestyle behaviors and helping to develop improvement strategies. This article describes the nursing experience of the authors in caring for an obese patient who had made several unsuccessful attempts to reduce weight. An intervention approach was used to review the patient's lifestyle. Using self-regulation theory, the authors identified that the patient's fat-related daily behavior included: lack of exercise, high-fat diet, and daily snacks consumed even late at night. The authors also helped the patient discover the reasons underlying his fat- related behavior and his previous failed attempts to lose weight and to develop a feasible improved approach that considered such. After six weeks of care, the patient's body weight had reduced and body fat and body mass index had decreased with no relapse. The patient further lost significant weight and body fat during the three-month follow up period. The authors would like to share with nursing professionals this approach to weight loss, with the hope that this case study can contribute to medical efforts to help obese patients not only lose weight but also prevent chronic illnesses.

Inconsistent information on levels of eating pathology in Asian Americans exist. We investigated whether there were differences in mean scores for eating disorder (ED) symptoms among Whites, Asian Americans, and individuals identifying as another race (i.e., non-Asian people of color [NAPOC]). Participants included 716 college students (M age = 19.23; SD = 1.65) from a southeastern university. ED symptoms were assessed with the Eating Pathology Symptom Inventory (EPSI). Internalizing symptoms were evaluated via the Depression Anxiety and Stress Scale (DASS). One-way ANOVAs investigated mean differences in symptoms between racial groups, with and without adjusting for sex, BMI, and internalizing symptoms. Overall, 16% (n = 114) of the sample identified as Asian American, 67% (n = 477) as White, and 17% (n = 125) as NAPOC. After correcting for multiple testing and adjusting for covariates, Asian Americans reported higher mean scores of purging, muscle building, and cognitive restraint (qs < 0.05) than Whites and NAPOC. Asian Americans also scored higher on restriction compared with Whites (qs < 0.05), as well as body dissatisfaction and negative attitudes toward obesity compared with NAPOC (qs < 0.05). These findings demonstrate the existence of racial differences among specific ED symptoms, highlighting the importance of considering these distinctions when diagnosing and treating EDs among diverse communities.

Binge eating is a transdiagnostic eating disorder symptom that can occur in patients with anorexia nervosa (AN), persisting after weight restoration, and impeding their recovery. However, little is known about the biological predictors of binge eating after AN weight restoration. The goals of this exploratory study of 73 females with AN were: (1) to examine changes in cortisol, the adrenocorticotropic hormone, norepinephrine, ghrelin (total and active), and leptin levels across the admission, discharge, and 3 months post-discharge from the inpatient AN weight restoration; and (2) to determine whether the target hormones were associated with objective or subjective binge eating (OBE or SBE). The participants completed the self-reported Eating Disorder Examination Questionnaire, Beck Anxiety Inventory, and Beck Depression Inventory-II, and provided fasting whole blood samples for hormone assays. The results showed significant changes in body mass index (BMI), cortisol, total ghrelin, and leptin levels over the three time points. The cortisol levels at admission and discharge were significantly associated with the number of SBE episodes at 3 months post-discharge. Findings suggest the need to replicate and confirm the role of cortisol in predicting the emergence of SBE and uncover the mechanisms underlying SBE and cortisol to prevent SBE and its negative consequences.
RESUMO
Weight stigma and binge eating have been found to be associated in Western populations; however, this relationship is understudied among Asian Americans. The aims of the study were to (1) investigate the prevalence of binge eating and its relationship with experienced weight stigma in higher-weight Asian Americans, and (2) examine whether the level of acculturation moderates this relationship. Data were collected from a cross-sectional study with 166 higher-weight Asian American adults living in North Carolina, United States. Demographic data, the frequency of experiencing weight stigma, the severity of binge eating, the levels of acculturation, the perceived racism against Asians, and perceived stress were assessed via self-reported questionnaires. The results indicated that experienced weight stigma was a significant independent predictor over and above the effects of other stressors, such as racism and general stress. The level of acculturation did not influence the relationship between the experienced weight stigma and binge eating after adjusting for relevant covariates. Our findings contribute to the limited literature examining weight stigma and binge eating among Asian American populations, highlighting that higher levels of experienced weight stigma are associated with a greater degree of binge eating.

A positive association between food addiction (i.e., an addiction to compulsively overeat highly palatable foods) and body dissatisfaction in college students exists. However, little is known about the underlying mechanisms. Eating expectancies, one's learning history regarding the association between eating and its consequences, may provide potential pathways linking food addiction and body dissatisfaction. In the current study, five eating expectancies (i.e., eating helps manage negative affect, eating is pleasurable and useful as a reward, eating leads to feeling out of control, eating enhances cognitive competence, and eating alleviates boredom) were evaluated as potential mediators between food addiction and body dissatisfaction in 738 college students (mean age = 19.21 ± 1.63, 61.4% female). Students completed the Eating Pathology Symptoms Inventory, Yale Food Addiction Scale, and Eating Expectancy Inventory. Adjusting for sex, age, race, and body mass index, structural equation modeling was used to examine the bi-directional mediation effects of the eating expectancies between food addiction and body dissatisfaction. Results showed a bi-directional positive association between food addiction and body dissatisfaction (ß = 0.12-0.26, standard error [SE] = 0.07-0.03, all p < 0.01) that was partially mediated by the expectancy that eating leads to feeling out of control, regardless of whether body dissatisfaction was included as the independent or dependent variable (ß = 0.15-0.36, SE = 0.05-0.02, all p < 0.01). Findings suggest the need to address the influence of expecting eating to lead to feeling out of control in interventions for co-occurring food addiction and body dissatisfaction among college students.

Weight stigma is a pervasive problem for Americans, but little is known about its impact on the health of Asian Americans. Authors examined the relationship between weight stigma and cortisol and whether acculturation moderated this relationship. Asian Americans (n = 166) with overweight or obesity completed questionnaires and provided a 50-mg hair sample to assay cortisol. Results revealed a negative correlation between weight stigma and cortisol. However, this was no longer significant after controlling of relevant covariates. The level of acculturation did not significantly moderate this relationship. The non-significant relationships among weight stigma, cortisol, and acculturation are discussed along with future directions.
RESUMO
A healthy lifestyle with sufficient physical activity (PA) can contribute to weight management. Yet, many people do not maintain a healthy lifestyle. To explain PA, we propose a model that incorporates the Theory of Planned Behavior (TPB) with weight-related self-stigma. We recruited 325 young adults to complete questionnaires regarding their physical activities, weight-related self-stigma, and TPB factors. We used structural equation modeling to examine the model fit and the path invariance across weight groups. The model showed excellent model fit, but path invariance was not supported. Weight-related self-stigma significantly explained the perceived behavioral control, behavioral intention, and engagement of PA. People without overweight and people with overweight have different considerations for PA. Weight-related self-stigma is important for PA as well. To promote a healthy lifestyle, healthcare providers should provide different suggestions or interventions that suit their patients' weight-related concerns.

OBJECTIVE: Eating disorder symptoms change in a predictable pattern over the menstrual cycle such that changes in symptoms are triggered by changes in the ovarian hormones estradiol (E2) and progesterone (P4). To date, work in this area has focused exclusively on young adult women. The objective of this pilot study was to examine the effect of E2 and P4 on eating disorder symptom change in midlife women during early perimenopause. METHOD: Participants included women aged 42-52 in early perimenopause (n=8). In-home self-assessments were completed for one menstrual cycle or 40-days, whichever occurred first. In-home self-assessments included collecting saliva samples each morning for E2 and P4 assays and completing online study questionnaires at the end of each day. Multilevel regression models examined the associations of E2 and P4 with daily symptoms of binge eating and body dissatisfaction. RESULTS: E2 was positively associated with binge eating when P4 was high, but not when P4 was low. E2 was inversely associated with body dissatisfaction when P4 was low, but positively associated with body dissatisfaction when P4 was high. However, the simple slopes for the effect of E2 at both high and low P4 were not significant for body dissatisfaction. CONCLUSIONS: Despite the pilot nature of this study, results are broadly consistent with the young adult literature indicating that P4 levels shape the impact of E2 on eating disorder symptoms. Larger studies with the inclusion of key moderators to account for individual heterogeneity are needed to confirm and extend these findings.

BACKGROUND: To investigate the risk factors associated with cardiovascular diseases and its relation to BMI, body fat mass and plasma leptin level among adolescents in Taitung, Taiwan. METHODS: A cross-sectional Taitung Children Heart Study for 500 young adolescents between ages 13 and 15 was conducted. Gender-specific regression models were used to determine the associations between BMI, percentage of body fat mass, plasma leptin level and seven CVDs risk factors (systolic and diastolic blood pressure, mean arterial pressure, triglycerides, total cholesterol, HDL-cholesterol and LDL-cholesterol) before and after adjusting for weight status and age. RESULTS: After adjusting for weight status and age, BMI was positively associated with systolic BP, triglycerides, LDL-cholesterol levels but negatively associated with HDL-cholesterol level in boys while positively associated with systolic and diastolic BP, mean arterial pressure, and LDL-cholesterol level in girls. The percentage of body fat mass was positively associated with triglycerides, total cholesterol, and LDL-cholesterol in boys while positively associated with systolic BP, total cholesterol, and LDL-cholesterol in girls. Plasma leptin was positively associated with triglycerides, total cholesterol and LDL-cholesterol in boys but no statistically significant associations with CVDs risk factors in girls. A strong relationship between the percentage of body fat mass and plasma leptin appeared among all participants (r=0.59, p<0.01). CONCLUSIONS: BMI, body fat mass and plasma leptin level may be used to identify certain CVDs risk factors among Taitung adolescents. Future researches could consider measuring body fat mass in the relationship of CVDs risk factors instead of plasma leptin among young adolescents.

OBJECTIVE: The purpose of this study was to investigate the association between the level of weight-related stigmatizing experiences and binge eating in overweight adults in southern Taiwan. METHODS: This study design was a cross-sectional questionnaire survey with convenience sample. A total of 141 questionnaires were analyzed. RESULTS: The study showed that 97.9% participants had at least one weight-related stigmatizing experience in their lifetime. The main sources of weight-related stigmatizing experiences were from either parents, relatives or doctors. BMI and age were significantly correlated with weight-related stigmatizing experiences. Furthermore, about 19.9% of participants experienced binge eating. The scores of the weight-related stigmatizing experiences and binge eating were positively correlated (r=0.33, p<0.01). The scores of the weight-related stigmatizing experiences and monthly income significantly explained factors of binge eating. CONCLUSIONS: The findings showed that there is a need to develop interventions to assist overweight people cope with weight-related stigmatization and prevent binge eating in the future.

Overweight and obesity are serious public health and medical problems among children and adults worldwide. Behavioural change has been demonstrably contributory to weight management programs. Behavioural change-based weight loss programs require a theoretical framework. We will review the transtheoretical model and the organisational development theory in weight management. The transtheoretical model is a behaviour theory of individual level frequently used for weight management programs. The organisational development theory is a more complicated behaviour theory that applies to behavioural change on the system level. Both of these two theories have their respective strengths and weaknesses. In this manuscript, we try to introduce the transtheoretical model and the organisational development theory in the context of weight loss programs among population that are overweight or obese. Ultimately, we wish to present a new framework/strategy of weight management by integrating these two theories together.
