ABSTRACT 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.

    ABSTRACT: Menopausal transition has been associated with emergence of metabolic abnormalities, which may increase risk for chronic medical conditions in women. This study compared metabolic function between premenopausal women (n = 152), postmenopausal women (n = 88), and men (n = 98) recruited for treatment studies for obesity co-occurring with binge eating disorder (BED), a high risk population for developing metabolic syndrome (MetS). Postmenopausal women were more likely than premenopausal women to show elevated total cholesterol (OR = 2.75; 95% CI = 1.56-4.80) and poor glycemic control (OR = 2.92; 95% CI = 1.32-6.33), but were more likely to have lower HDL levels (OR = 0.36; 95% CI = 0.19-0.68). These became non-significant after adjusting for age. Both pre- and postmenopausal women were less likely than age-matched men to show elevated levels of triglycerides (OR = 0.27; 95% CI = 0.13-0.53 [postmenopausal], OR = 0.29; 95% CI = 0.16-0.53 [premenopausal]), blood pressure (OR = 0.48; 95% CI = 0.25-0.91 [postmenopausal], OR = 0.40; 95% CI = 0.23-0.69 [premenopausal]), and less likely to have MetS (OR = 0.41; 95% CI = 0.21-0.78 [postmenopausal], OR = 0.46; 95% CI = 0.27-0.79 [premenopausal]). Premenopausal women were also less likely to have elevated fasting glucose level (OR = 0.50; 95% CI = 0.26-0.97) than age-matched men. Among obese women with BED, aging may have a more profound impact on metabolic abnormalities than menopause, suggesting the importance of early intervention of obesity and symptoms of BED. Active monitoring of metabolic function in obese men with BED may also be critical.

    ABSTRACT: This study sought to examine differences in the nutritional composition of binges, both qualitatively and quantitatively, between participants with binge eating disorder (BED) and bulimia nervosa (BN) taken from a sample of treatment-seeking Black and White women. Overall qualitative and quantitative differences between diagnostic categories, regardless of ethnicity, were also explored.Method Patients seeking treatment for eating disorders were assessed on binge content. Black (n=26) and White (n=26) participants were matched on age and body mass index (BMI).ResultsThe binges of individuals with BN were lower in percent protein, but higher in calories, carbohydrates, and sugar, than those individuals with BED. However, there was little difference as a function of ethnicity between treatment-seeking Black and White women.DiscussionPreliminary data suggest that health professionals are faced with similar binge eating pathology, regardless of ethnicity, despite, probably, etiologic variation. The importance of the role of ethnicity in the expression of eating disorders is discussed.
