Group and longitudinal intra-individual networks of eating disorder symptoms in adolescents and young adults at-risk for an eating disorder.

ABSTRACT: Several studies have identified risk factors that predict future onset of eating disorders (ED) in adolescence, however, it is currently unknown how specific ED symptom dynamics operate both across time and within individuals. Advances in network methodologies allow for the study of how dynamic symptoms interrelate and predict each other within-persons and across time. In the current study, we used longitudinal group-level (N = 1272) (addressing symptom interrelations across people and across time; between-subjects, contemporaneous, and temporal networks) and intra-individual (symptom interrelations within each person and across time; contemporaneous and temporal networks) network analyses (subset n = 50) in prospective 48-month interview data in at-risk adolescents and young adults. We computed between-subject networks (how symptoms are associated on average, for group sample only), contemporaneous networks (how symptoms are associated at one time point, accounting for previous time points), and temporal networks (examining how symptoms predict each other across time). We replicated prior network results which suggest that overvaluation of weight and shape are central in at-risk adolescents and young adults. We found that individual networks (n = 1 networks) were highly variable across individuals. Overall, our results show how both group-level and longitudinal intra-individual network analysis can inform our understanding of how EDs develop in adolescence and point to the importance of conceptualizing development on an individual level of analysis.

Wearable Cameras Reveal Large Intra-Individual Variability in Timing of Eating among Young Adults.

Project description:Studies have shown that young adults follow less structured eating patterns compared with older cohorts. This may have implications for dietary assessment methods which rely on memory and structured meal patterns. Our aim was to describe the intra-individual variation of eating times in young adults aged 18-30 years. Participants (n = 41) wore an Autographer camera that captured first-person perspective images every 30 s for three consecutive days. All images were timestamped and those showing food consumption were used to extract data such as the timing of the first and last eating occasions (EOs), number of EOs per day, and length of eating window. Intra-individual variability was calculated from these data using composite phase deviation (CPD) and coefficient of variation (CV). The number of individuals with high or very high variability was 28 and 18 for timing of first and last EOs, respectively (CPD > 1.70), and 27 and 17 for number of EOs and eating window, respectively (CV > 20%). In this sample of young adults, the lack of regularity in eating patterns should be considered when selecting a dietary assessment method.

Does childhood bullying predict eating disorder symptoms? A prospective, longitudinal analysis.

Project description:ObjectiveBullying is a common childhood experience with enduring psychosocial consequences. The aim of this study was to test whether bullying increases risk for eating disorder symptoms.MethodTen waves of data on 1,420 participants between ages 9 and 25 were used from the prospective population-based Great Smoky Mountains Study. Structured interviews were used to assess bullying involvement and symptoms of anorexia nervosa and bulimia nervosa as well as associated features. Bullying involvement was categorized as not involved, bully only, victim only, or both bully and victim (bully-victims).ResultsWithin childhood/adolescence, victims of bullying were at increased risk for symptoms of anorexia nervosa and bulimia nervosa as well as associated features. These associations persisted after accounting for prior eating disorder symptom status as well as preexisting psychiatric status and family adversities. Bullies were at increased risk of symptoms of bulimia and associated features of eating disorders, and bully-victims had higher levels of anorexia symptoms. In terms of individual items, victims were at risk for binge eating, and bully-victims had more binge eating and use of vomiting as a compensatory behavior. There was little evidence in this sample that these effects differed by sex. Childhood bullying status was not associated with increased risk for persistent eating disorder symptoms into adulthood (ages 19, 21, and 25).DiscussionBullying predicts eating disorder symptoms for both bullies and victims. Bullying involvement should be a part of risk assessment and treatment planning for children with eating problems.

Food Addiction in a Group of Italian Adolescents Diagnosed for Eating Disorder.

Project description:Research in patients with Eating Disorders (EDs) showed high rates of Food Addiction (FA) even in restrictive subtypes. The majority of studies were conducted on adult population. The present work aimed to describe and compared FA in adolescents diagnosed for different EDs and to evaluate its association with patients' psychopathology. Patients aged 12-18 y were included in the analysis. FA was assessed using the Yale Food Addiction Scale 2.0. The rate of FA was of 49.4% in the whole sample (n = 87, F = 90.8%) and of 53.7% in patients diagnosed with restrictive anorexia nervosa. No difference in FA frequency was detected between EDs. A worse psychopathological picture was found in patients diagnosed with FA. Higher age, higher score to the Eating Attitudes Test-26 and to the Eating Disorder Inventory-3's Interoceptive Deficits scale have been detected as the major predictors of FA in our sample. FA may be considered a transnosographic construct, not linked to the subtype of ED but to patients' personal characteristics and, in particular, to age and interoceptive deficits. A worse psychopathology might be considered a risk factor for the presence of FA in EDs.

Resting-state functional network connectivity underlying eating disorder symptoms in healthy young adults.

Project description:Previous neuroimaging research of eating disorders such as anorexia nervosa and bulimia nervosa has mainly focused on clinical patients, indicating the crucial role of intrinsic connectivity networks involved in aberrant behavioral control (i.e., executive control network), reward reactivity (i.e., basal ganglia network), and excessive self-focused and body-focused ruminations (i.e., default mode network) in the onset and maintenance of eating disturbances. However, examinations of large-scale resting-state networks that support the role of cognitive control, reward sensitivity, and self-directed thinking in disordered eating have rarely involved non-clinical samples from the general population. This study, involving a total of 693 healthy young adults (68.69% females; mean age, 18.37 years), investigated these issues by using pre-defined functional regions of interest from the executive control network, basal ganglia network, default mode network, and a seed-based region of interest-to-region of interest approach. After statistically controlling for differences in age, sex, body mass index, and head motion, we observed significant associations of higher levels of eating disorder symptoms, especially bulimia-type eating (i.e., binge eating and a combination of binge eating and compensatory behaviors, such as purging via self-induced vomiting or laxative use, and compulsive exercise), with weaker intra-network and inter-network functional synchrony. These results remained significant after excluding underweight, overweight, and obese participants. These findings suggest that these neural circuits may play a key role in the symptoms of disordered eating in healthy adults. They further reveal that the less efficient information exchange within and between intrinsic networks associated with self-referential thinking, inhibitory control, and reward sensitivity are strongly related to eating disorder symptoms.

Nicotine dependence predicts cannabis use disorder symptoms among adolescents and young adults.

Project description:PURPOSE:We evaluate if cigarette smoking and/or nicotine dependence predicts cannabis use disorder symptoms among adolescent and young adult cannabis users and whether the relationships differ based on frequency of cannabis use. METHODS:Data were drawn from seven annual surveys of the NSDUH to include adolescents and young adults (age 12-21) who reported using cannabis at least once in the past 30?days (n?=?21,928). Cannabis use frequency trends in the association between cigarette smoking, nicotine dependence and cannabis use disorder symptoms were assessed using Varying Coefficient Models (VCM's). RESULTS:Over half of current cannabis users also smoked cigarettes in the past 30?days (54.7% SE 0.48). Cigarette smoking in the past 30?days was associated with earlier onset of cannabis use, more frequent cannabis use and a larger number of cannabis use disorder symptoms compared to those who did not smoke cigarettes. After statistical control for socio-demographic characteristics and other substance use behaviors, nicotine dependence but not cigarette smoking quantity or frequency was positively and significantly associated with each of the cannabis use disorder symptoms as well as the total number of cannabis symptoms endorsed. Higher nicotine dependence scores were consistently associated with the cannabis use disorder symptoms across all levels of cannabis use from 1?day used (past month) to daily cannabis use, though the relationship was strongest among infrequent cannabis users. CONCLUSION:Prevention and treatment efforts should consider cigarette smoking comorbidity when addressing the increasing proportion of the US population that uses cannabis.

Disordered eating, self-esteem, and depression symptoms in Iranian adolescents and young adults: A network analysis.

Project description:ObjectiveThe network theory of psychopathology examines networks of interconnections across symptoms. Several network studies of disordered eating have identified central and bridge symptoms in Western samples, yet network models of disordered eating have not been tested in non-Western samples. The current study tested a network model of disordered eating in Iranian adolescents and college students, as well as models of co-occurring depression and self-esteem.MethodParticipants were Iranian college students (n= 637) and adolescents (n = 1,111) who completed the Eating Disorder Examination-Questionnaire (EDE-Q), Rosenberg Self-Esteem Scale (RSES) and Beck Depression Inventory, Second Edition (BDI-II). We computed six Glasso networks and identified central and bridge symptoms.ResultsCentral disordered eating nodes in most models were a desire to lose weight and discomfort when seeing one's own body. Central self-esteem and depression nodes were feeling useless and self-dislike, respectively. Feeling like a failure was the most common bridge symptom between disordered eating and depression symptoms. With exception of a few differences in some edges, networks did not significantly differ in structure.DiscussionDesire to lose weight was the most central node in the networks, which is consistent with sociocultural theories of disordered eating development, as well as prior network models from Western-culture samples. Feeling like a failure was the most central bridge symptom between depression and disordered eating, suggesting that very low self-esteem may be a shared correlate or risk factor for disordered eating and depression in Iranian adolescents and young adults.

Longitudinal associations between emotion regulation skills, negative affect, and eating disorder symptoms in a clinical sample of individuals with binge eating.

Project description:OBJECTIVE:Although deficits in emotion regulation have been implicated in the maintenance of binge eating, few prospective studies have examined longitudinal associations between emotion regulation and eating disorder symptoms, which are needed to test these theoretical models. METHOD:Using a naturalistic design, the current study utilized longitudinal multilevel analyses to examine whether improvements in emotion regulation during treatment are associated with decreased binge eating frequency and eating disorder cognitions in a heterogeneous sample of adults with binge eating (N?=?97). Analyses also accounted for between- and within-person differences in negative affect to inform specific targets for intervention. RESULTS:Significant within-person associations between emotion regulation, negative affect, and eating disorder severity support hypotheses that emotion dysregulation and negative affect co-occur with eating disorder psychopathology. Only between-person differences in negative affect demonstrated associations with binge eating frequency over time. DISCUSSION:Data suggest that momentary interventions targeting negative affect and emotion regulation skills may decrease eating disorder cognitions, but not binge eating frequency, among adults with binge eating.

Affective symptoms and intra-individual variability in the short-term course of cognitive functioning in bipolar disorder.

Project description:Few studies have examined the short-term course of cognitive impairments in bipolar disorder (BD). Key questions are whether trajectories in symptoms covary with cognitive function and whether BD is associated with increased intra-individual variability in cognitive abilities.Forty-two out-patients with BD and 49 normal comparison (NC) subjects were administered a battery of neuropsychological tests at baseline, 6, 12 and 26 weeks, along with concurrent ratings of depressive and manic symptom severity. Mixed-effects regressions were used to model relationships between time, diagnosis and symptom severity on composite cognitive performance. Within-person variance in cognitive functioning across time was calculated for each subject.BD patients had significantly worse performance in cognitive ability across time points, but both groups showed significant improvement in cognitive performance over repeated assessments (consistent with expected practice effects). BD was associated with significantly greater intra-individual variability in cognitive ability than NCs; within-person variation was negatively related to baseline cognitive ability in BD but not NC subjects. Changes in affective symptoms over time did not predict changes in cognitive ability.Moderate changes in affective symptoms did not covary with cognitive ability in BD. The finding of elevated intra-individual variability in BD may reduce capacity to estimate trajectories of cognitive ability in observational and treatment studies.

Eating disorder symptoms in Asian American college students.

Project description: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.

Presence of eating disorder symptoms in patients with obsessive-compulsive disorder.

Project description:BACKGROUND:Obsessive-compulsive disorder (OCD) is common in patients with eating disorders (EDs). There is a lack of research investigating the presence of ED symptoms among patients with OCD, despite concerns that many of these patients may be at high risk for EDs. Our objective was to assess the presence of ED symptoms in patients receiving treatment for OCD. METHODS:Adult patients with OCD (n = 132, 71% females) and controls (n = 260, 90% females) completed the Eating Disorder Examination-Questionnaire (EDE-Q) at admission to a specialized OCD outpatient unit. A small subset of patients (n = 22) also completed the EDE-Q 3-months after end of treatment. RESULTS:At the group-level, mean EDE-Q scores did not differ significantly between female patients and controls. However, female patients compared to controls were significantly more likely to score above the EDE-Q cut-off (23% vs. 11%) and have a probable ED (9% vs. 1%), indicating elevated rates of ED symptoms in the clinical range. There was no evidence of elevated rates of ED symptoms in male patients, though sample sizes were small. Preliminary follow-up data showed that certain ED symptoms improved significantly from admission to 3-month follow-up. CONCLUSIONS:Our findings suggest that while ED symptoms are not generally elevated in female patients with OCD, a considerable subset of female patients may have a clinical ED or be at high risk of developing one. Clinicians should be alert to ED symptoms in female patients with OCD, and our findings raise the issue of whether ED screening of female patients with OCD is warranted.
