Selective processing of body image words in women at-risk for developing an eating disorder: a preliminary study.

We evaluated the utility of the Modified Stroop task as a measure of body image concerns in women at-risk for an eating disorder. Data were collected among 31 participants from an eating disorder prevention program. The Modified Stroop was significantly associated with overeating episodes and an explicit measure of shape concern. The traditional Stroop effect was found while the Modified Stroop effect was non-significant. The results raise questions about the Modified Stroop task's utility in identifying at-risk women. Methodological and clinical implications are discussed.

Home and neighbourhood built environment features in family-based treatment for childhood obesity.

BACKGROUND: Family-based behavioural weight loss treatment (FBT) for childhood obesity helps families develop strategies to facilitate healthy choices in their home and other environments (e.g. home neighbourhood). The current study examines how the home food environment, both pre-FBT and post-FBT, and the neighbourhoods in which families live are associated with child weight and weight-related outcomes in FBT. METHODS: Parent-child dyads (n = 181) completed a 16-session FBT programme and completed home environment, anthropometric and child dietary/activity assessments at pre-FBT and post-FBT. Parents reported on availability of food, electronics and physical activity equipment in the home. The neighbourhood food and recreation environments around each dyad's residence was characterized using existing data within a geographic information system. RESULTS: Families successfully made healthy home environment modifications during FBT. Regression models showed reducing RED (e.g. high-energy-dense and low-nutrient-dense) foods and electronics in the home during FBT had positive effects on child weight and weight-related outcomes. No neighbourhood food or recreation environment variables were significantly related to outcomes, although having a larger density of public recreation spaces was associated with increases in physical activity at the trend-level. CONCLUSIONS: Modifying the home environment, specifically reducing RED foods and electronics, may be particularly important for FBT success.

Weight change in the management of youth-onset type 2 diabetes: the TODAY clinical trial experience.

BACKGROUND: The Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial documented that metformin plus rosiglitazone, but not metformin plus lifestyle intervention, provided superior durability of glycemic control relative to metformin monotherapy. OBJECTIVES: We examined weight changes among TODAY participants that completed at least 6 months of treatment, evaluated predictors of lifestyle outcome, and examined whether weight changes were related to cardiometabolic outcomes across treatment arms. METHODS: The 595 youth with type 2 diabetes, (85.1% of randomized participants aged 11-17 years) completed assessments of weight-related and cardiometabolic measures at months 0, 6, 12 and 24. Repeated measures models were used to investigate associations over time. RESULTS: Lifestyle intervention did not enhance outcome relative to metformin alone and no predictors of response to lifestyle treatment were identified. However, changes in percent overweight across treatment arms were associated with changes in multiple cardiometabolic risk factors, and decreases of ≥ 7% in overweight were associated with significant benefits over 24 months. CONCLUSIONS: Although adjunctive intensive lifestyle intervention did not improve weight-related outcomes, weight changes in the full TODAY sample were associated with small, but significant improvements in cardiometabolic status, highlighting the importance of optimizing weight management in youth with T2DM.

A comparison of black and white women with binge eating disorder.

OBJECTIVE: Binge eating disorder was introduced in DSM-IV as a psychiatric disorder needing further study. This community-based study describes the relationship between race and clinical functioning in black and white women with and without binge eating disorder. METHOD: A group of 150 women with binge eating disorder (52 black, 98 white) and a race-matched group of 150 healthy comparison subjects were recruited from the community. Eating and psychiatric symptoms were assessed through interviews and self-report. RESULTS: Black and white women with binge eating disorder differed significantly on numerous eating disorder features, including binge frequency, restraint, history of other eating disorders, treatment-seeking behavior, and concerns with eating, weight, and shape. Black and white healthy comparison subjects differed significantly in obesity rates. CONCLUSIONS: For both black and white women, binge eating disorder was associated with significant impairment in clinical functioning. Yet, racial differences in clinical presentation underscore the importance of considering race in psychopathology research.

A multicomponent program for nutrition and physical activity change in primary care: PACE+ for adolescents.

BACKGROUND: Most adolescents do not meet national recommendations for nutrition and physical activity. However, no studies of physical activity and nutrition interventions for adolescents conducted in health care settings have been published. The present study was an initial evaluation of the PACE+ (Patient-centered Assessment and Counseling for Exercise plus Nutrition) program, delivered in primary care settings. PARTICIPANTS: Adolescents aged 11 to 18 years (N = 117) were recruited from 4 pediatric and adolescent medicine outpatient clinics. Participants' mean (SD) age was 14.1 (2.0) years, 37% were girls, and 43% were ethnic minorities. INTERVENTION: Behavioral targets were moderate physical activity, vigorous physical activity, fat intake, and fruit and vegetable intake. All patients completed a computerized assessment, created tailored action plans to change behavior, and discussed the plans with their health care provider. Patients were then randomly assigned to receive no further contact or 1 of 3 extended interventions: mail only, infrequent telephone and mail, or frequent telephone and mail. MEASURES: Brief, validated, self-report measures of target behaviors were collected at baseline and 4 months later. RESULTS: All outcomes except vigorous physical activity improved over time, but adolescents who received the extended interventions did not have better 4-month outcomes than those who received only the computer and provider counseling components. Adolescents who targeted a behavior tended to improve more than those who did not target the behavior, except for those who targeted vigorous physical activity. CONCLUSIONS: A primary care-based interactive health communication intervention to improve physical activity and dietary behaviors among adolescents is feasible. Controlled experimental research is needed to determine whether this intervention is efficacious in changing behaviors in the short- and long-term.

Bias in binge eating disorder: how representative are recruited clinic samples?

The aim of this study was to investigate sampling bias as it affects recruited clinic samples of binge eating disorder (BED). Demographic and clinical characteristics of a recruited clinic sample were compared with a community sample. The 2 groups met the same operational definition of BED and were assessed using the same primarily interview-based methods. Ethnicity, severity of binge eating, and social maladjustment were found to increase treatment seeking among participants with BED rather than levels of psychiatric distress or comorbidity. These findings suggest that previous studies using recruited clinic samples have not biased estimates of psychiatric comorbidity in BED.

Group cognitive-behavioral therapy and group interpersonal psychotherapy for the nonpurging bulimic individual: a controlled comparison.

This study evaluated the effectiveness of group cognitive-behavioral treatment (CBT) and group interpersonal psychotherapy (IPT) for binge eating. Fifty-six women with nonpurging bulimia were randomly assigned to 1 of 3 groups: CBT, IPT, or a wait-list control (WL). Treatment was administered in small groups that met for 16 weekly sessions. At posttreatment, both group CBT and group IPT treatment conditions showed significant improvement in reducing binge eating, whereas the WL condition did not. Binge eating remained significantly below baseline levels for both treatment conditions at 6-month and 1-year follow-ups. These data support the central role of both eating behavior and interpersonal factors in the understanding and treatment of bulimia.

Comorbid psychopathology in binge eating disorder: relation to eating disorder severity at baseline and following treatment.

Individuals with binge eating disorder (BED) have high rates of comorbid psychopathology, yet little is known about the relation of comorbidity to eating disorder features or response to treatment. These issues were examined among 162 BED patients participating in a psychotherapy trial. Axis I psychopathology was not significantly related to baseline eating disorder severity, as measured by the Structured Clinical Interview for DSM-III-R (SCID-I and SCID-II) and the Eating Disorder Examination. However, presence of Axis II psychopathology was significantly related to more severe binge eating and eating disorder psychopathology at baseline. Although overall presence of Axis II psychopathology did not predict treatment outcome, presence of Cluster B personality disorders predicted significantly higher levels of binge eating at 1 year following treatment. Results suggest the need to consider Cluster B disorders when designing treatments for BED.

Reducing risk factors for eating disorders: comparison of an Internet- and a classroom-delivered psychoeducational program.

This controlled trial compared Internet- (Student Bodies [SB]) and classroom-delivered (Body Traps [BT]) psychoeducational interventions for the reduction of body dissatisfaction and disordered eating behaviors/attitudes with a control condition. Participants were 76 women at a private university who were randomly assigned to SB, BT, or a wait-list control (WLC) condition. Measures of body image and eating attitudes and behaviors were measured at baseline, posttreatment, and 4-month follow-up. At posttreatment, participants in SB had significant reductions in weight/shape concerns and disordered eating attitudes compared with those in the WLC condition. At follow-up, disordered behaviors were also reduced. No significant effects were found between the BT and WLC conditions. An Internet-delivered intervention had a significant impact on reducing risk factors for eating disorders.

Maintenance following a very-low-calorie diet.

The authors posed 2 questions in this randomized study of maintenance procedures in which participants were followed for 15 months after completion of a very-low-calorie diet: Would stimulus narrowing during the reintroduction of solid food, achieved by the use of prepackaged foods, improve weight losses and the maintenance of those losses as compared with the use of regular food? Would reintroduction of foods dependent on progress in losing or maintaining weight be superior to reintroduction on a time-dependent basis? Neither the stimulus narrowing condition nor the reintroduction procedure enhanced either maximum weight loss or maintenance of those losses. The stimulus narrowing condition appeared to be poorly tolerated; compliance and attendance were poorer in this condition than in the regular food condition.

Assessing the specific psychopathology of binge eating disorder patients: interview or self-report?

Research addressing the assessment of binge eating and associated eating disorder psychopathology has steadily increased in recent years. Few studies have examined the relationship between the various assessment methods. This study compared an investigator-based interview, the Eating Disorder Examination (EDE), with a self-report version of that interview, the EDE-Q. Fifty-two individuals (six men and 46 women) with binge eating disorder (BED) completed both instruments. Modest-to-good agreement and significant correlations (P < 0.0001) were found between the two methods on all four subscales assessing specific eating disorder psychopathology (i.e., Restraint, Eating Concern, Weight Concern, and Shape Concern subscales). However, higher levels of disturbance were consistently reported on the EDE-Q than the EDE interview. The two methods were not significantly or reliably related to one another when assessing binge eating. This may be due in part to the difficulty inherent in identifying binges in subjects with BED. Examination of individual item scores suggest that it might be possible to improve the performance of the EDE-Q by clarifying the definitions of certain complex features, although this should not be at the expense of compromising the practical utility of its self-report format.

Teasing, body image, and self-esteem in a clinical sample of obese women.

This study examined the relationship of physical-appearance-related teasing history to body image and self-esteem in a clinical sample of adult obese females. The frequency of being teased about weight and size while growing up was negatively correlated with evaluation of one's appearance and positively correlated with body dissatisfaction during adulthood. Self-esteem was unrelated to teasing history but covaried significantly with body image measures. Subjects with early-onset obesity reported greater body dissatisfaction than did subjects with adult-onset obesity. The findings suggest that being teased about weight/size while growing up may represent a risk factor for the development of negative body image and that self-esteem and body image covary.

Self-directed hostility and family functioning in normal-weight bulimics and overweight binge eaters.

The aim of this study was to examine whether overweight binge eaters demonstrate similar perceptions of family interactions and views of the self as do normal-weight bulimics. We compared 37 obese binge eaters and 37 normal-weight bulimics to 38 normal-weight non-bulimic controls, and 10 overweight nonbulimic controls on the Bulimia Test (BULIT). Profile of Mood States (POMS), Structural Analysis of Social Behavior (SASB) Short Form, which includes measure of hostility of family interactions and self-directed hostility; the Family Interaction Survey (FIS), and a measure of history of physical and sexual abuse and familial psychopathology. Both normal-weight bulimics and overweight binge eaters differed from nonbulimic controls across all measures of symptomatology, family functioning, history of abuse, familial psychopathology, and self-directed hostility. Normal-weight bulimics demonstrated significantly higher BULIT scores and self-directed hostility than did overweight binge eaters. Post hoc analysis showed that among binge eaters and bulimics, self-directed hostility accounted for a significant percentage of the variance of BULIT scores when controlling for the effects of age, BMI, family hostility, and mood. The possible role of self-directed hostility in the maintenance of bulimic symptomatology is discussed.

Psychological concomitants of cystic fibrosis in children and adolescents.

Thirty cystic fibrosis (CF) and 30 matched control children and their parents were administered several psychiatric inventories including the child (DICA) and parent (DICA-P) versions of the Diagnostic Interview for Children and Adolescents, the Child Behavior Check List, the Hopelessness Scale, and the Piers-Harris Children's Self-Concept Scale. Data analysis revealed few differences in either psychopathological symptoms or psychiatric diagnoses between the CF and control children. The differences which did emerge were either physical in nature (reflecting somatic complaints) or did not depart enough from normal scores to merit the label of high psychopathology. The results are discussed in terms of the growing evidence that CF children do not suffer from greater psychopathology than do normal children.

Obesity prevention in defined (high school) populations.

BACKGROUND: A challenge for the widespread dissemination of Internet-based programs designed to produce weight maintenance/loss in defined (high school) populations is to adapt them to local needs and interests, whereas demonstrating effectiveness and salience for both universal and targeted populations. OBJECTIVE: The objective of this study is to examine the feasibility of providing an inexpensive, Internet-based universal (healthy weight regulation) and targeted (weight maintenance/loss) health program to all ninth-grade students in a high school serving a lower socioecnomic status, diverse population. DESIGN: A total of 118 normal-weight and 64 overweight/obese students in the same ninth-grade class completed a baseline screen and were allocated to a healthy weight regulation program or a weight-loss maintenance program. Both groups simultaneously received a 10-week Internet-based intervention. Program implementation required minimal teacher time. Measurement included self-reported fruit, vegetable and high-fat/-calorie food consumption, self-reported change in body mass index (BMI), weight and shape concerns, as well as program engagement. RESULTS: The program was successfully implemented in nine classes, with minimal help from the investigators. There was a significant increase in self-reported consumption of fruits and vegetables (P=0.001). There was a significant reduction in self-reported BMI in the overweight/obese group (P=0.001). Students found the program helpful and engaging. There was a significant reduction in weight and shape concerns in the high-risk female students, consistent with a reduced risk for the development of an eating disorder. Providing a universal and targeted online healthy weight regulation program to ninth-grade students is feasible and inexpensive. The results suggest the program can serve as 'core' for future studies using adaptive, continuous quality-improvement designs.

Anorexia nervosa trios: behavioral profiles of individuals with anorexia nervosa and their parents.

BACKGROUND: Anorexia nervosa (AN) is associated with behavioral traits that predate the onset of AN and persist after recovery. We identified patterns of behavioral traits in AN trios (proband plus two biological parents). METHOD: A total of 433 complete trios were collected in the Price Foundation Genetic Study of AN using standardized instruments for eating disorder (ED) symptoms, anxiety, perfectionism, and temperament. We used latent profile analysis and ANOVA to identify and validate patterns of behavioral traits. RESULTS: We distinguished three classes with medium to large effect sizes by mothers' and probands' drive for thinness, body dissatisfaction, perfectionism, neuroticism, trait anxiety, and harm avoidance. Fathers did not differ significantly across classes. Classes were distinguished by degree of symptomatology rather than qualitative differences. Class 1 (approximately 33%) comprised low symptom probands and mothers with scores in the healthy range. Class 2 ( approximately 43%) included probands with marked elevations in drive for thinness, body dissatisfaction, neuroticism, trait anxiety, and harm avoidance and mothers with mild anxious/perfectionistic traits. Class 3 (approximately 24%) included probands and mothers with elevations on ED and anxious/perfectionistic traits. Mother-daughter symptom severity was related in classes 1 and 3 only. Trio profiles did not differ significantly by proband clinical status or subtype. CONCLUSIONS: A key finding is the importance of mother and daughter traits in the identification of temperament and personality patterns in families affected by AN. Mother-daughter pairs with severe ED and anxious/perfectionistic traits may represent a more homogeneous and familial variant of AN that could be of value in genetic studies.

Toward an understanding of risk factors for anorexia nervosa: a case-control study.

BACKGROUND: Prospective, longitudinal studies of risk factors for anorexia nervosa (AN) are lacking and existing cross-sectional studies are generally narrow in focus and lack methodological rigor. Building on two studies that used the Oxford Risk Factor Interview (RFI) to establish time precedence and comprehensively assess potential risk correlates for AN, the present study advances this line of research and represents the first case-control study of risk factors for AN in the USA. METHOD: The RFI was used for retrospective assessment of a broad range of risk factors, while establishing time precedence. Using a case-control design, 50 women who met DSM-IV criteria for AN were compared to those with non-eating disorder DSM-IV psychiatric disorders (n=50) and those with no psychiatric disorder (n=50). RESULTS: Women with psychiatric disorders reported higher rates of negative affectivity, maternal and paternal parenting problems, family discord, parental mood and substance disorder, and physical and sexual abuse than women with no psychiatric disorder. Women with AN specifically reported greater severity and significantly higher rates of negative affectivity, perfectionism and family discord, and higher parental demands than women with other psychiatric disorders. The role of weight and shape concerns was most salient in the year preceding onset of AN. CONCLUSIONS: Convergent data identifying common risk factors as well as those more severe in the development of AN are emerging to inform longitudinal risk factor and prevention studies for this disorder.

Eating disorders: a women's health problem in primary care.

Eating disorders pose a significant risk to the health and psychological well-being of adolescent girls and adult women, yet a sizeable number of health care practitioners do not routinely assess for eating disorders. This paper provides an overview of what is currently understood about the nature and assessment of eating disorders. Diagnostic features, psychiatric comorbidity, and medical complications of anorexia nervosa, bulimia nervosa, and binge eating disorder are discussed. We suggest ways that health care providers can incorporate assessment for eating disorders and referral for treatment into their routine clinical care practices.

Psychological treatment of bulimia nervosa and binge eating disorder.

The field of eating disorders has grown rapidly, amassing an impressive body of treatment research in the past 20 years. In particular, researchers have focused on binge eating problems, which include bulimia nervosa (BN) and the more recently recognized binge eating disorder (BED). Numerous controlled treatment trials have shown cognitive-behavioral therapy (CBT) to be equally or more efficacious than any other BN treatment to which it has been compared. Although CBT also seems to be effective for BED, research is in a preliminary stage. Further combinations and adaptations of treatments for BED are needed to address the additional problem of obesity in this population. Preliminary data suggest that behavioral weight control treatment for BED is effective in reducing binge eating, and it may have the added benefit of weight loss. Interpersonal psychotherapy (IPT), the combination of CBT and medication, and self-help manuals are promising treatment alternatives for both BN and BED. Future treatment trials should include longer-term followup periods and more consistent definitions of successful treatment outcome. In addition, further study is needed in the areas of treatment nonresponders, pre-treatment predictors, a stepped-care treatment model, and methods for a wider dissemination of validated treatments.

Impact of interpersonal and ego-related stress on restrained eaters.

OBJECTIVE: This study examined the impact of different types of stress, one interpersonal and two ego-related versus a control condition, on the eating behavior of individuals with varying degrees of dietary restraint. METHOD: Eighty-two females were randomly assigned to one of three manipulations or a control group, and then all groups completed an ice cream taste test. RESULTS: A significant interaction revealed that for participants with higher restraint, those in the stressful manipulations ate significantly more than participants in the control group. Further, the pattern of consumption based on restraint for the interpersonal group differed from the other three conditions. In the interpersonal group, the greater the restraint, the more participants ate, whereas in the other three conditions, the pattern was reversed although not significantly so. DISCUSSION: Findings are discussed in terms of the role that interpersonal stress plays in the eating behavior of dieters and potential implications regarding the development of eating disorders.
