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.

Comparison of binge eating disorder and bulimia nervosa in a community sample.

OBJECTIVE: This study examined the relationship between binge eating disorder (BED), a newly proposed eating disorder, and bulimia nervosa (BN). METHOD: Three groups recruited from the community were compared: women with BED (n = 150), women with purging BN (n = 48), and women with nonpurging BN (n = 14). RESULTS: The three groups did not differ significantly in education, weight or shape concern, and current or lifetime prevalence of nine major mental disorders. Women with BED, compared with women with purging BN, were older, less likely to have a history of anorexia nervosa, and less likely to have been treated for an eating disorder. Obesity was more commonly associated with BED than with either subtype of BN. DISCUSSION: Our results lend some support to BED as an eating disorder distinct from purging BN. More research is needed to clarify the position of nonpurging BN relative to BED and purging BN.

Reducing risk factors for eating disorders: targeting at-risk women with a computerized psychoeducational program.

OBJECTIVE: This controlled study evaluated whether an 8-week program offered over the Internet would significantly decrease body image dissatisfaction, disordered eating patterns, and preoccupation with shape/weight among women at high risk for developing an eating disorder. METHOD: Fifty-six college women were recruited on the basis of elevated scores (> or =110) on the Body Shape Questionnaire (BSQ). Psychological functioning, as measured by the Eating Disorder Inventory Drive for Thinness (EDI-DT) subscale, Eating Disorder Examination-Questionnaire (EDE-Q), and the BSQ, was assessed at baseline, posttreatment, and at 10-week follow-up. RESULTS: All participants improved over time on most measures, although effect sizes suggest that the program did impact the intervention group. DISCUSSION: Findings suggest that technological interventions may be helpful for reducing disordered eating patterns and cognitions among high-risk women. Future research is needed to assess whether such programs are effective over time for prevention of and reduction in eating disorder symptomatology.

An interactive internet-based intervention for women at risk of eating disorders: a pilot study.

OBJECTIVE: The Internet serves as a potentially effective method of treatment delivery through widespread education and interaction via synchronous Internet relay chat (IRC). The current study explores the feasibility of IRC in the delivery of an eating disorders prevention intervention. METHOD: This small pilot study describes the delivery of an efficacious eating disorder treatment using a novel medium. The on-line sessions are based on cognitive-behavioral treatment and are facilitated by a moderator. In addition to feasibility, preliminary evidence of acceptability and efficacy for an on-line intervention with college-aged women is reported. RESULTS: Results indicate that IRC is an acceptable and feasible format for treatment delivery. In addition, descriptive and qualitative data suggest that this method of treatment delivery is potentially effective. DISCUSSION: This pilot study provides increased knowledge of the viability of treatment delivery over the Internet, specifically, a psychoeducational IRC for eating disorder prevention.

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.

Changes in eating disorder symptoms with pediatric obesity treatment.

OBJECTIVE: To evaluate the effects of behavioral, family-based treatment on disordered eating and child behavior problems for obese 8- to 12-year-old children. STUDY DESIGN: We examined disordered eating in children and parents using the Kids' Eating Disorder Survey (KEDS) and the Binge Eating Scale, respectively; and psychologic problems in children and their parents using the Child Behavior Checklist and Symptom Checklist-90, respectively, in 47 families who participated in a family-based obesity treatment program. RESULTS: Obese children showed significant decreases (-12.5 +/- 13.5) in percent overweight, internalizing problems (-7.0 +/- 7.3), and total behavior problems (-4.8 +/- 6.6) and increases in behavioral competence (3.7 +/- 5.0) over 2 years of measurement; and their parents showed significant decreases in weight (-5.0 +/- 8.3 kg) and reductions in parental distress (-2.3 +/- 7.6) and in disturbed eating and weight-related cognition (-3.2 +/- 5.3). No significant changes were observed in total KEDS (-0.2 +/- 1.9), weight dissatisfaction (-0.3 +/- 1.7), or purging/restricting (0.2 +/- 0.6) scores. Decreases in total KEDS were related to decreases in total behavior problems and externalizing behavior problems. CONCLUSIONS: These results document improvements in child behavior problems and competence and no change in symptoms of disordered eating in a standardized behavioral weight control program.

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.

Effects of a physical activity intervention on body image in university seniors: project GRAD.

Project GRAD (Graduate Ready for Activity Daily) was a randomized controlled study to teach university seniors behavioral skills necessary for increasing and/or maintaining physical activity habits in preparation for the transition to working adult roles after graduation. This study examines the secondary effects of this intervention on body image concerns among college-aged men and women. Three hundred thirty-eight undergraduates (54%female, Mage = 24years, SD = 1.95; MBody Mass Index = 24.26, SD = 4.0) were studied. The sample was 61/% Anglo, 16% Latino, 16% Asian/Pacific Islander, 4% African American, and 3% Native American/Other Body image concerns were assessed at pre- and posttreatment using 2 subscales of the Eating Disorder Inventory: Drive for Thinness and Body Dissatisfaction. Because the latter concentrates on body parts typically associated with female concerns (e.g., thighs, hips, buttocks), a parallel scale was developed to target body parts that may be of more concern to men (e.g., legs, shoulders, arms, stomach). Results indicated that compared to the control group, women in the intervention showed a significant increase in drive for thinness without any changes in body dissatisfaction. For men, there were no significant changes in drive for thinness or body dissatisfaction. These results suggest that physical activity interventions may have some negative consequences of increasing concerns about thinness in women. This negative effect occurred despite intervention content designed to prevent concern over eating, dieting, and the importance of weight. Health promotion studies should include assessments of potential negative side effects.

Recurrent binge eating in black American women.

CONTEXT: Recurrent binge eating is a core diagnostic feature of bulimia nervosa and binge eating disorder, and in samples of white women has been associated with obesity and psychiatric symptoms. Eating disorders have been believed to occur primarily among white women; in fact, the limited preliminary data available suggest that black women may be as likely as white women to report binge eating. OBJECTIVE: To examine race differences in prevalence of behavioral symptoms of eating disorders and clinically significant recurrent binge eating. DESIGN: Community survey. SETTING: General community in Connecticut and Boston, Mass. PARTICIPANTS: A community sample of 1628 black women and 5741 white women (mean age, 29.7 years) participated in a telephone survey designed to ascertain the presence, during the preceding 3 months, of binge eating and extreme weight control behaviors (vomiting, laxative or diuretic abuse, or fasting). MAIN OUTCOME MEASURE: Interviewer-based phone assessment of recurrent binge eating and behavioral symptoms of eating disorders. RESULTS: Black women were as likely as white women to report binge eating or vomiting during the preceding 3 months, and were more likely to report fasting and the abuse of laxatives or diuretics. Recurrent binge eating was more common among black women than among white women. In both race groups, recurrent binge eating was associated with elevated body weight and increased psychiatric symptoms. CONCLUSION: Results suggest that recurrent binge eating is a significant problem among black and white women. Health professionals need to be ready to respond to this health risk behavior.

Eating pathology and obesity in women at risk for breast cancer recurrence.

OBJECTIVE: This cross-sectional study investigated the relationship among obesity, depressive symptoms, eating attitudes and behaviors, and dietary intake. It compared women at risk for recurrence of breast cancer and women who had not been diagnosed with breast cancer and were recruited from the same community and age group (middle-aged and older). METHOD: Body mass index (BMI), dietary intake, self-reported depressive symptoms, and eating disorder psychopathology (assessed with the Eating Disorder Examination - Questionnaire [EDE-Q]) were examined in women who had been diagnosed with breast cancer (n = 56) and the comparison group of women with no breast cancer history (n = 52). Multivariate regression analysis was used to identify factors independently associated with global and subscale EDE-Q scores and BMI. RESULTS: BMI and depressive symptoms were significantly and independently associated with global and subscale EDE-Q scores in women at risk for breast cancer recurrence and women with no breast cancer history. Dietary restriction was also significantly associated with EDE-Q scores in the group with no breast cancer history. CONCLUSIONS: An association among obesity, depressive symptomatology, and abnormal eating attitudes and behavior may affect response to standard nutritional interventions in women at risk for breast cancer recurrence.

Using the eating disorder examination to identify the specific psychopathology of binge eating disorder.

OBJECTIVE: The clinical features of binge eating disorder (BED) are not well established. Therefore, a comprehensive assessment of the specific psychopathology of BED as compared to anorexia nervosa (AN) and bulimia nervosa (BN) is warranted. This comparison was the aim of the present study. METHOD: Detailed ratings from an investigator-based interview, the Eating Disorders Examination (EDE), were compared across three groups of female patients: those with BED, AN, and BN, as well as normal-weight and overweight control subjects. RESULTS: When comparing BED to AN and BN, patients with BED had lower levels of restraint, eating concerns comparable to AN patients but lower than BN patients, and weight and shape concerns comparable to BN patients but higher than AN patients. Significantly more eating disorder psychopathology was found for BED patients as compared to the overweight controls on all bar the EDE restraint subscale. On the majority of individual EDE items, BED patients' scores were similar to those of AN and BN patients, including importance of shape and weight in self-evaluation and preoccupation with shape and weight. No significant relationship was found between BED patients' degree of overweight and eating psychopathology. DISCUSSION: Our findings support the status of BED as an eating disorder and suggest that the elevated EDE scores reflect the combined impact of being objectively overweight and having disordered cognitions and behaviors about eating, shape, and weight.

Subthreshold binge eating disorder.

OBJECTIVE: To examine the clinical features of subthreshold binge eating disorder (BED). METHOD: Participants were recruited directly from the community as part of an ongoing study of risk factors for BED. Forty-four women with subthreshold BED were compared with 44 women with BED and 44 healthy controls on demographic characteristics, body mass index (BMI), eating disorder symptomatology, and psychiatric distress. Diagnoses were established using the Eating Disorder Examination (EDE). Participants completed the EDE-Questionnaire, the Brief Symptom Inventory, and were measured and weighed. RESULTS: Adjusting for significant group differences in BMI, the two eating disorder groups did not differ significantly on measures of weight and shape concern, restraint, psychiatric distress, and history of seeking treatment for an eating or weight problem. DISCUSSION: Given the importance of diagnostic status for access to treatment, further evaluation of the severity criterion specified for BED is needed.

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.

The Yale Interpersonal Stressor (YIPS): affective, physiological, and behavioral responses to a novel interpersonal rejection paradigm.

Given links between interpersonal functioning and health as well as the dearth of truly interpersonal laboratory stressors, we present a live rejection paradigm, the Yale Interpersonal Stressor (YIPS), and examine its effects on mood, eating behavior, blood pressure, and cortisol in two experiments. The YIPS involves one or more interaction(s) between the participant and two same-sex confederates in which the participant is made to feel excluded and isolated. In Experiment 1, 50 female undergraduates were randomly assigned to the YIPS or a control condition. Participants in the YIPS condition experienced greater negative affect and less positive affect than did those in the control condition. Further, restrained eaters ate more following the YIPS than did nonrestrained eaters. In Experiment 2, 25 male and female undergraduates completed the YIPS. The YIPS induced significant increases in tension, systolic blood pressure (SBP), and diastolic blood pressure (DBP) from baseline, while significantly decreasing positive affect. The YIPS appeared particularly relevant for women, resulting in significantly greater increases in cortisol and SBP for women compared to men. The YIPS, then, provides an alternative to traditional, achievement-oriented laboratory stressors and may allow for the identification of individuals most vulnerable to interpersonal stress.

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.

Natural course of a community sample of women with binge eating disorder.

OBJECTIVE: A community sample of women with binge eating disorder (BED) was followed for a period of 6 months, in order to examine the natural course of the disorder. METHOD: Baseline, 3-, and 6-month assessments were conducted. The following variables were examined: eating disorder symptomatology, importance of weight or shape, psychopathology, social adjustment, childhood sexual abuse, childhood obesity, parental obesity, and parental psychopathology. RESULTS: After the 3-month follow-up, 10 of the original sample of 31 participants dropped out of the study; drop-outs were more likely to have reported a history of sexual abuse. Of the 21 remaining participants, 11 continued to suffer from full-syndrome BED at 6-month follow-up, while the remaining 10 appeared to be in partial remission. There were no significant baseline predictors of outcome. CONCLUSION: It appears that for some women with BED, the eating disorder improves with a decrease in binge eating and importance of weight or shape. For others, the eating disorder symptoms remain constant.

Marital status, marital satisfaction, and body image dissatisfaction.

OBJECTIVE: This study examined whether married individuals have comparable body image disturbance to nonmarried individuals and whether the quality of a marital relationship is significantly related to body image disturbance in a sample of dieters. METHOD: Measures of marital status, marital satisfaction, and body dissatisfaction were administered to a sample of 16,377 subjects who had tried to lose weight at least once within the previous 3 years. RESULTS: Marital status was not associated with increased body dissatisfaction. Marital satisfaction was significantly related to body dissatisfaction when controlling for age, body mass index, self-esteem, and gender. DISCUSSION: Body dissatisfaction occurs at comparable levels among married and single individuals and the study of marital functioning among eating-disordered individuals represents a large gap in the literature.
