RESUMO

OBJECTIVE: Eating disorders (EDs) are associated with elevated suicide. Low body mass index (BMI) and frequency of purging and binge eating represent severity criteria for EDs and distinguish full-threshold EDs from other specified feeding and eating disorders (OSFED). However, no work has taken a transdiagnostic approach to studying whether severity of these or other features is associated with suicidal ideation (SI) and attempts. METHOD: We examined diagnostic status, ED features, and SI and attempts in a large, transdiagnostic, community sample of 257 women with EDs and 45 controls without a current or past ED in the United States using the EDs Examination interview and the Structured Clinical Interview for the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). RESULTS: SI and suicide attempts (SA) were elevated in OSFED compared to controls but did not differ between OSFED and full-threshold EDs. Higher BMI predicted increased SI. Number of purging methods, but not frequency, was related to history of SA. Binge episode frequency and size were not significant predictors. CONCLUSIONS: OSFED presents with elevated SI and SA, and ED severity criteria that distinguish OSFED from full-threshold EDs do not predict SI or SA. Suicide risk assessments should be implemented universally across EDs in clinical practice.

RESUMO

OBJECTIVES: Negative urgency is associated with short-term maintenance of binge eating and purging in unselected samples. The current study used an eating disorder sample to test the hypothesis that negative urgency maintains bulimia nervosa (BN) and purging disorder (PD) at long-term follow-up. It was also hypothesized that baseline differences in negative urgency between BN and PD would remain at follow-up. METHODS: Secondary analyses were conducted on a sample of women who engaged in recurrent self-induced vomiting (n = 68; 52.9% BN; 47.1% PD). Women completed diagnostic interviews and questionnaires at baseline and at a mean (SD) of 5.95 (1.58) years follow-up (range = 2.51-9.62; retention rate = 75%). RESULTS: Negative urgency did not predict eating disorder diagnostic status, recovery status, or global eating pathology at follow-up (p's = .06-.83). There were no significant differences in negative urgency across women with BN and PD at follow-up (p = .16). However, post hoc analyses indicated that negative urgency was not stable across time (ICC = .102). Increases in negative urgency from baseline to follow-up were associated with greater global eating pathology at follow-up (p = .002). CONCLUSION: Results suggest negative urgency does not predict long-term eating disorder maintenance. Negative urgency may not be a stable personality trait but rather an indicator of overall poor emotion regulation. Future research should confirm that changes in negative urgency predict chronic eating pathology over long durations of follow-up in women who have increasing negative urgency across time.

RESUMO

OBJECTIVE: Binge-eating spectrum disorders (BESD) involve large eating episodes accompanied by a sense of loss of control that occur in individuals with body weights spanning the full body mass index (BMI) spectrum. While research links BESD with peripheral inflammation, this literature is limited by underpowered studies and a failure to control for confounding variables that could promote inflammation independent of dysregulated eating, specifically elevated body adiposity and depression. Our study examined plasma interleukin-6 (IL-6), a marker of peripheral inflammation, in a sample of women with BESD and non-eating disorder controls, controlling for BMI, body adiposity, and depression. METHOD: Participants (N = 94) included women with BESD (n = 73) or no eating disorder (n = 21) who completed structured clinical interviews in a larger study, selected to represent BMI categories ranging from underweight to obese in both groups. Fasting blood samples were processed for plasma IL-6 concentration via enzyme-linked immunosorbent assays. In addition to assessing group differences in plasma IL-6, exploratory analyses examined associations between IL-6 and biological and clinical markers of BESD. RESULTS: Significantly elevated plasma IL-6 was found in women with BESD, relative to controls, that was not accounted for by BMI, adiposity, or depression. Plasma IL-6 was positively correlated with plasma leptin concentration, clinical assessments of eating disorder severity, and participants' largest self-reported eating episode. DISCUSSION: Peripheral inflammation is specifically linked to presence of dysregulated eating independently from weight, adiposity, and depression in BESD. Future research should probe the potential role of neuroinflammation in altered eating behavior. PUBLIC SIGNIFICANCE: This study provides the first demonstration that inflammation, characterized by elevated plasma IL-6 concentration, is uniquely associated with dysregulated eating in a transdiagnostic group of individuals with BESD. A better understanding of whether immune factors contribute to dysregulated eating could help identify novel biological targets for intervention.

RESUMO

BACKGROUND: Trait-level emotion regulation (ER) difficulties are associated with eating disorders (EDs) transdiagnostically. However, little research has examined whether within-person fluctuations in ER longitudinally predict ED behaviors in daily life or the mechanisms of ER effects. Investigating daily ER could help us better understand why people experience ED behaviors at a given time. We examined whether day-to-day changes in adaptive (e.g., cognitive reappraisal) and maladaptive (e.g., rumination) ER longitudinally predicted core ED behaviors (binge eating, purging, dieting) and whether changes in affect mediated effects. METHOD: Female participants (N = 688) ages 15-30 from the Michigan State University Twin Registry reported their adaptive and maladaptive ER use, negative affect (NA), positive affect (PA), binge eating, purging, and dieting on 49 consecutive days. Using structural equation modeling, we examined whether within-person fluctuations in ER predicted same- and next-day ED behaviors and whether changes in affect mediated longitudinal ER effects. RESULTS: Greater maladaptive ER predicted increased likelihood of same-day binge eating and next-day binge eating and purging. The association between maladaptive ER and next-day binge eating and purging was mediated by increased next-day NA. In contrast, dieting was more closely related to changes in PA. Adaptive ER did not predict reduced likelihood of any ED behavior. CONCLUSIONS: Maladaptive ER may longitudinally increase risk for binge eating and purging by amplifying NA. Interventions focused on decreasing maladaptive ER and subsequent NA might help disrupt binge eating-purging cycles. Conversely, results add to evidence that PA fluctuations may play a unique role in maintaining restrictive behaviors. PUBLIC SIGNIFICANCE: Little is known about how daily changes in emotion regulation may impact disordered eating. We found that maladaptive emotion regulation (e.g., rumination) was associated with a higher likelihood of binge eating and purging on the next day because it predicted increased next-day negative affect. In contrast, dieting was more closely tied to fluctuations in positive affect. Targeting daily emotion regulation and affective processes may help disrupt cycles of disordered eating.

RESUMO

Sexual abuse or assault (SA) history is associated with eating disorder severity and psychiatric comorbidity, including post-traumatic stress disorder (PTSD). Beyond persistent alterations in mood and cognitions characterizing PTSD, PTSD due to SA may contribute to greater increases in negative affect and body image concerns following food intake in bulimic syndromes (BN-S). To test this, participants (n = 172) with BN-S who reported PTSD due to SA, PTSD due to other forms of trauma, or neither completed clinical interviews and momentary reports of negative affect and shape/weight preoccupation before and after food intake. Participants with PTSD, regardless of trauma source, reported higher purging frequency whereas PTSD due to SA was associated with more frequent loss of control eating. For one task, changes in negative affect following food intake differed across the three groups. Negative affect decreased significantly in participants with PTSD without SA whereas nonsignificant increases were observed in those with PTSD with SA. Results of the present study suggest that source of trauma in PTSD may impact likelihood that eating regulates affect and provide insight into ways current treatments may be adapted to better target purging in BN-S comorbid with PTSD.

RESUMO

OBJECTIVE: Theories suggest that elevated negative affect and weight/shape concerns explain both who is affected by bulimic symptoms as well as when bulimic symptoms occur, suggesting that individual differences predict within-subject differences. However, few studies have tested this theoretical premise. METHOD: In the present study, participants (N = 119) diagnosed with bulimia nervosa (N = 57), purging disorder (N = 31), and non-eating disorder controls (N = 31) completed measures of negative affect and weight/shape concerns and later made momentary affect and weight/shape concerns ratings before and after an ad lib meal. RESULTS: State negative affect and weight/shape concerns increased post-meal. No moderating effect of trait negative affect was observed for state affect. In contrast, between-subject differences in weight/shape concerns moderated within-subject increases in state weight/shape concerns. Diagnostic group did not account for this effect. DISCUSSION: Findings point to viable treatment targets for disordered eating. Targeting elevated weight/shape concerns early in interventions could facilitate reductions in purging after food intake for bulimia nervosa and purging disorder. PUBLIC SIGNIFICANCE: In the present study, individual differences in weight/shape concerns at baseline predicted greater increases in state weight/shape concerns following eating. These effects were maintained when considering possible differences related to presence and type of eating disorder. Results suggest that targeting weight/shape concerns earlier in treatment may be important for reducing maladaptive responses to eating across eating disorders.

RESUMO

OBJECTIVE: We sought to (1) compare self-concept clarity (SCC; the degree to which a person possesses a confidently defined, internally consistent, and stable sense of self) between female participants with and without eating disorders, (2) examine associations between SCC deficits and severity of eating disorder specific and related psychopathology in individuals with eating disorders, and (3) determine if there is a unique association between SCC deficits and eating disorder severity, controlling for related psychopathology. METHOD: Participants (M age = 23.16 years) with eating disorders (n = 121) and controls (n = 63) completed semi-structured clinical interviews and self-report assessments. RESULTS: SCC deficits were significantly greater in the eating disorder compared to the control group. In the eating disorder group, greater SCC deficits were significantly associated with greater severity of eating pathology, depression, impulsivity, and trait anxiety. In a hierarchical regression analysis, significant associations between SCC deficits and Eating Disorder Examination (EDE) Global scores were better accounted for by shared variance with anxiety. DISCUSSION: SCC deficits may reflect a transdiagnostic feature related to the severity of a range of mental health problems, suggesting potential benefit of transdiagnostic interventions.

RESUMO

BACKGROUND: Stress is associated with binge eating and emotional eating (EE) cross-sectionally. However, few studies have examined stress longitudinally, limiting understanding of how within-person fluctuations in stress influence EE over time and whether stress is a risk factor or consequence of EE. Additionally, little is known regarding how the biological stress response relates to EE. METHODS: We used an intensive, longitudinal design to examine between-person and within-person effects of major life stress, daily stress, and cortisol on EE in a population-based sample of women (N = 477; ages 15-30; M = 21.8; s.d. = 3.0) from the Michigan State University Twin Registry. Participants reported past year major life stress, then provided daily ratings of EE and stress for 49 consecutive days. Hair cortisol concentration (HCC) was collected as a longitudinal biological stress measure. RESULTS: Women reported greater EE when they experienced greater mean stress across days (between-person effects) or greater stress relative to their own average on a given day (within-person effects). Daily stress was more strongly associated with EE than major life stress. However, the impact of daily stress on EE was amplified in women with greater past year major life stress. Finally, participants with lower HCC had increased EE. CONCLUSIONS: Findings confirm longitudinal associations between stress and EE in women, and highlight the importance of within-person shifts in stress in EE risk. Results also highlight HCC as a novel biological stress measure that is significantly associated with EE and may overcome limitations of prior physiological stress response indicators.

RESUMO

OBJECTIVE: Increased weight suppression, the difference between an individual's highest and current weight at present height, predicts binge eating among eating disorder samples. Less is known about this relationship in non-clinical samples of individuals with a history of higher weight. METHODS: Lifetime highest BMI was tested as a moderator of the relationship between weight suppression and binge eating in three independent samples (N = 1740). RESULTS: At the bivariate level, weight suppression was not associated with binge eating in any sample (p's ≥ 0.20). Lifetime highest BMI moderated the relationship between weight suppression and binge eating in Sample 1 (p = .04), such that greater weight suppression was associated with lower binge eating among those with a history of higher weight (i.e., BMI = 40 kg/m2). In Samples 2 and 3, the lifetime highest BMI by weight suppression interaction term was not significant and dropped from the model (p's = 0.10-0.12). Accounting for age, gender, and lifetime highest BMI, greater weight suppression was associated with lower binge eating scores (p's < 0.04). A meta-analysis combining results revealed a small but significant interaction effect (r = 0.07, p = .02). CONCLUSIONS: Findings highlight the importance of investigating the generalizability of eating disorder risk and maintenance theories across the weight spectrum. Weight loss may not increase risk for binge eating among those with a history of higher weight. Future work should replicate and extend this finding using longitudinal designs. More research is needed to elucidate which weight loss motivations and/or behaviors are most closely linked to binge eating.

RESUMO

BACKGROUND: Prior work supports delayed gastric emptying in anorexia nervosa and bulimia nervosa (BN) but not binge-eating disorder, suggesting that neither low body weight nor binge eating fully accounts for slowed gastric motility. Specifying a link between delayed gastric emptying and self-induced vomiting could offer new insights into the pathophysiology of purging disorder (PD). METHODS: Women (N = 95) recruited from the community meeting criteria for DSM-5 BN who purged (n = 26), BN with nonpurging compensatory behaviors (n = 18), PD (n = 25), or healthy control women (n = 26) completed assessments of gastric emptying, gut peptides, and subjective responses over the course of a standardized test meal under two conditions administered in a double-blind, crossover sequence: placebo and 10 mg of metoclopramide. RESULTS: Delayed gastric emptying was associated with purging with no main or moderating effects of binge eating in the placebo condition. Medication eliminated group differences in gastric emptying but did not alter group differences in reported gastrointestinal distress. Exploratory analyses revealed that medication caused increased postprandial PYY release, which predicted elevated gastrointestinal distress. CONCLUSIONS: Delayed gastric emptying demonstrates a specific association with purging behaviors. However, correcting disruptions in gastric emptying may exacerbate disruptions in gut peptide responses specifically linked to the presence of purging after normal amounts of food.

RESUMO

Emerging research indicates that binge eating is prevalent among older adult women. This study explored the characteristics of older women (aged 60+ years) with objective binge episodes (OBE) in later-life, including age of onset, distress, and frequency of OBE. Data consist of telephone clinical interviews conducted with individuals presenting for participation in a biomedical study of older women with OBE to establish inclusion criteria. Of 71 participants interviewed, 77.5% met DSM-5 criteria for OBE (≥1/week for ≥3 months); 33.3% reported OBE onset before age 40, 17.9% reported midlife onset (ages 40-55), and 48.7% reported late-life onset (56+). Regarding distress, older women with OBE in later-life reported themes of age-related self-blame surrounding eating, loss of control, and cognitive fixation on satiation. Among older women with OBE in later-life, onset in mid- to later-life may be relatively common. Furthermore, distress regarding OBEs was significant, highlighting the need for intervention research among this population.

RESUMO

This study examined differences in mental health in older adult women before versus during the COVID-19 pandemic. Participants who were community dwelling (N = 227) included n = 67 women aged 60-94 in the pre-pandemic group and n = 160 women aged 60-85 in the peri-pandemic group who completed self-report measures assessing mental health and quality of life (QOL). We compared mental health and QOL indices across the pre- and peri-pandemic groups. Results indicated that the peri-pandemic group reported higher anxiety (F = 4.94, p = .027) than the pre-pandemic group. No other significant differences emerged. Given the differential effects in this pandemic across SES, we conducted exploratory analyses investigating differences by income group. Controlling for education and race, within the pre-pandemic group, women with lower income reported worse physical function compared to the mid- and high-income groups. Within the peri-pandemic group, women with lower income reported worse anxiety, poorer sleep, and poorer QOL (physical function, role limitations due to physical problems, vitality, and pain) than high-income individuals. Overall, women who reported lower income reported worse mental health and QOL than those with high-income, especially during the pandemic. This indicates that income might act as a buffer for older women against negative psychological outcomes of the COVID-19 pandemic.

RESUMO

While boys and men have historically been underrepresented in eating disorder research, increasing interest and research during the twenty-first century have contributed important knowledge to the field. In this article, we review the epidemiology of eating disorders and muscle dysmorphia (the pathological pursuit of muscularity) in boys and men; specific groups of men at increased risk for eating disorders; sociocultural, psychological, and biological vulnerability factors; and male-specific assessment measures. We also provide an overview of current research on eating disorder and muscle dysmorphia prevention efforts, treatment outcomes, and mortality risk in samples of boys and men. Priorities for future research are including boys and men in epidemiological studies to track changes in incidence, identifying (neuro)biological factors contributing to risk, eliminating barriers to treatment access and utilization, and refining male-specific prevention and treatment efforts.

RESUMO

BACKGROUND: COVID-19 was associated with significant financial hardship and increased binge eating (BE). However, it is largely unknown whether financial stressors contributed to BE during the pandemic. We used a longitudinal, cotwin control design that controls for genetic/environmental confounds by comparing twins in the same family to examine whether financial hardship during COVID-19 was associated with BE. METHODS: Female twins (N = 158; Mage  = 22.13) from the Michigan State University Twin Registry rated financial stressors (e.g., inability to afford necessities) daily for 49 consecutive days during COVID-19. We first examined whether financial hardship was associated with BE phenotypes across the full sample. We then examined whether cotwins who differed on financial hardship also differed in BE. RESULTS: Participants who experienced greater mean financial hardship across the study had significantly greater dimensional BE symptoms, and participants who experienced greater financial hardship on a given day reported significantly more emotional eating that day. These results were replicated in cotwin control analyses. Twins who experienced more financial hardship than their cotwin across the study reported greater dimensional BE symptoms than their cotwin, and participants who experienced more financial hardship than their cotwin on a given day reported greater emotional eating that day. Results were identical when restricting analyses to monozygotic twins, suggesting associations were not due to genetic confounds. CONCLUSIONS: Results suggest that BE-related symptoms may be elevated in women who experienced financial hardship during COVID-19 independent of potential genetic/environmental confounds. However, additional research in larger samples is needed. PUBLIC SIGNIFICANCE: Little is known regarding how financial difficulties during the COVID-19 pandemic may have contributed to increased binge eating (BE). We found preliminary evidence that financial hardship during COVID-19 may be associated with greater rates of BE-related symptoms even when comparing twins from the same family. While additional research is needed, results suggest that people who experienced financial hardship during COVID-19 may be at increased risk for BE.

RESUMO

This study explored the generality versus specificity of two trait-liability factors for externalizing problems-disinhibition and callousness-in the concurrent and prospective prediction of symptoms of conduct disorder, attention-deficit/hyperactivity disorder (ADHD), and substance use (i.e., alcohol use disorder and history of illicit substance use). Disinhibition involves an impulsive, unrestrained cognitive-behavioral style; callousness entails a dispositional lack of social-emotional sensitivity. Participants were European adolescents from the multisite IMAGEN project who completed questionnaires and clinical interviews at ages 14 (N = 1,504, Mage = 14.41, 51.13% female) and 16 (N = 1,407, Mage = 16.46, 51.88% female). Disinhibition was related concurrently and prospectively to greater symptoms of conduct disorder, ADHD, and alcohol use disorder; higher scores on a general externalizing factor; and greater likelihood of having tried an illicit substance. Callousness was selectively related to greater conduct disorder symptoms. These findings indicate disinhibition confers broad liability for externalizing spectrum disorders, perhaps due to its affiliated deficits in executive function. In contrast, callousness appears to represent more specific liability for antagonistic (aggressive/exploitative) forms of externalizing, as exemplified by antisocial behavior. Results support the utility of developmental-ontogenetic and hierarchical-dimensional models of psychopathology and have important implications for early assessment of risk for externalizing problems.

RESUMO

This multi-method, two-study investigation tested the hypothesis that, controlling for guilt and negative affect, shame increases following binge eating. Support for this hypothesis constitutes the first step in testing the theory that shame mediates the link between binge eating and comorbid psychopathology. Study 1 employed a laboratory binge-eating paradigm in n = 51 women [21 with bulimia nervosa, 30 controls]. Study 2 employed a naturalistic test of prospective relationships among binge eating, shame, guilt, and negative affect in n = 302 college women over three months. In Study 1, women with bulimia nervosa reported increases in shame that were not explained by changes in guilt or negative affect, following laboratory binge eating, compared with controls. In Study 2, baseline binge eating predicted increased shame at follow-up independently of guilt and negative affect. Should shame prove to mediate the link between binge eating and comorbid disorders, interventions to reduce shame may be useful for those who binge.

RESUMO

BACKGROUND: While negative affect (NA) typically increases risk for binge eating, the ultimate impact of NA may depend on a person's ability to regulate their emotions. In this daily, longitudinal study, we examined whether emotion regulation (ER) modified the strength of NA-dysregulated eating associations. METHODS: Women (N = 311) from the Michigan State University Twin Registry first reported dimensional binge eating symptoms and broad ER difficulties (e.g., limited emotional awareness, difficulty controlling emotional impulses). Participants then rated use of adaptive (cognitive reappraisal, social sharing, situation modification, and acceptance) and maladaptive (rumination, expressive suppression, and self-criticism) ER strategies, emotional eating (EE), objective binge eating (OBE), and NA once daily for 49 consecutive days. RESULTS: There were several main effects of ER on binge-eating pathology in both between-person (i.e., comparing women who differed on average) and within-person (i.e., examining fluctuations in variables day-to-day) analyses. Between-person, greater broad ER difficulties, greater maladaptive strategy use, and lower adaptive strategy use were all associated with greater binge-eating pathology. Within-person, greater maladaptive strategy use was associated with greater odds of OBE on that day and on the following day. However, neither broad ER difficulties nor use of specific strategies moderated associations between NA and dysregulated eating in between- or within-person analyses. CONCLUSIONS: While ER is independently associated with risk for dysregulated eating, it may not fully mitigate the impact of NA. Additional strategies (e.g., decreasing environmental stressors and increasing social support) may be needed to minimize NA and its impact on dysregulated eating. PUBLIC SIGNIFICANCE: Negative affect (NA; e.g., sadness, guilt) increases dysregulated eating risk. Because NA is sometimes unavoidable, we examined whether emotion regulation (ER; i.e., how a person responds to their emotions) might impact whether NA leads to dysregulated eating. Although more effective ER was associated with less dysregulated eating overall, ER did not impact the association between NA and dysregulated eating. Other approaches may therefore be needed to mitigate NA-dysregulated eating associations.

RESUMO

BACKGROUND: One type of overnutrition, binge eating (BE; eating an unusually large amount of food with loss of control), is prevalent among older adult women. Yet, little is known about the clinical significance of this eating disorder pathology in older adults, especially in relation to health outcomes used in geriatrics, while controlling for associations with body mass index (BMI). METHOD: Women (N = 227) aged 60-94 completed two measures of BE and health/wellness questionnaires online. We used multivariable analyses to compare women with Clinical-frequency BE (≥ weekly frequency), Subclinical-frequency BE (< weekly), and No BE on health/wellness outcomes controlling for BMI. We conducted partial correlations controlling for BMI to examine associations between BE severity and health indices. RESULTS: Controlling for BMI, the Clinical-frequency BE group reported poorer health-related quality of life (physical function, role limitations due to both emotional and physical problems, vitality, emotional wellbeing, social function, and pain) and poorer psychological health (depression, body image) compared to both Subclinical-frequency BE and No BE. The Clinical-frequency BE group also reported poorer sleep, nutritious food consumption, general health, and positive affect compared to No BE. Associations between a separate measure of BE severity and health indices confirmed findings from group comparisons. CONCLUSION: Weekly BE may offer a promising screening benchmark for identifying one type of overnutrition in older women that is associated with numerous indicators of poorer health, independent of the effects of BMI. More research is needed to understand risks for and consequences of BE unique to older adult women. Binge eating (BE; eating an unusually large amount of food with loss of control), is prevalent among older adult women and is associated with health problems in younger populations. Yet, little is known about how BE is related to other health problems in older adults. We compared health behaviors, physical health, health-related quality of life, and psychological health between older adult women who reported weekly or more frequent BE (i.e., Clinical BE), those with low frequency BE (i.e., Subclinical BE), and those with no BE, while accounting for BMI. Older women in the Clinical BE group reported poorer health-related quality of life, more depression symptoms, and worse body image compared to the Subclinical BE and No BE groups. Compared to the No BE group, the Clinical BE group also reported poorer sleep, less frequent consumption of nutritious foods, worse health, and less frequent positive emotions. Using a separate measure of BE severity, we found similar associations with these health outcomes.
