The symptom checklist-27-plus has demonstrated good psychometric properties in various samples, but clinical data have not yet been published. Data from 690 mostly young female patients with eating disorders show reliabilities ranging from acceptable to very good (Cronbachs ? between 0.76 und 0.89). Data from intake and discharge show a good ability to measure change (Cohen’s d between 0.27 und 1.31). At intake, patients display a very high symptom load, which has decreased significantly at discharge. HubMed – eating

Besides food restriction, hyperactivity is considered a key behavioral trait of anorexia nervosa (AN), playing a major role in the pathogenesis and progression of the disorder. However, the underlying neurophysiology remains poorly understood. We used functional magnetic resonance imaging during two affective go/no-go tasks to probe inhibitory control in response to stimuli depicting physical activity versus inactivity and food versus non-food in AN patients compared to 26 healthy athlete and non-athlete controls. We hypothesized that neural correlates of behavioral inhibition are biased by the emotional information of the stimuli in AN patients, leading to a differential neural inhibitory pattern during the two tasks. Indeed, we found reduced response inhibition for food and non-food images in the putamen, while stimuli depicting physical activity resulted in an exaggerated response of the prefrontal cortex and cerebellum in AN patients. However both AN patients and athletes revealed an increased response in the somatosensory cortex to physical activity stimuli. These results suggest that physical activity stimuli might place an increased demand on the inhibitory control system in AN patients. The resulting hyperactivity of the prefrontal cortex and cerebellum may lead to altered executive function and motor control, sustaining increased physical activity in AN patients. HubMed – eating

Background: The Chilean population has inadequate lifestyles and high prevalence ofchronic diseases. Aim: To analyze eating behaviors, nutritional status and history ofprevious diseases, in students of higher education. Material and Methods: Cross-sectional study in students of 54 higher education centers across the country. They answered a survey about dietary habits, physical activity, smoking, previous diseases and opinion oftheir nutritional condition. Weight and height were measured under standardized conditions and nutritional status classified according to body mass index. Results: We studied 6,823 students aged 17 to 29 years. Forty seven percent did not have breakfast and 35% did not have lunch every day. A low proportion had a daily consumption of vegetables (51.2%), fruits (39.4%) and dairy products (57.5%). There was a high frequency of soft drinks, chips, cakes and sweets consumption. Seventy six percent were sedentary, 40.3% smokers and 27.4% overweight or obese. The latter had a significantly higher frequency ofdiabetes, hypertension and hypercholesterolemia. There was a poor agreement between actual nutritional status and self-perception, especially in males (Kappa index 0.38). Recipients of a food scholarship provided by the Ministry of Education ate lunch usually with a higher frequency (p < 0.05). Conclusions: A high prevalence of inadequate eating and physical activity patterns in these young subjects with good educational level was observed. The food scholarship has some positive effects, although differences in socioeconomic levels limited comparisons. HubMed – eating


[Validation of the Spanish version of the Eating Disorders Diagnostic Scale].

Background: The Eating Disorders Diagnostic Scale (EDDS) is a self-administered low cost psychometric instrument with excellent levels of temporal reliability and validity. Aim: To adapt and validate the EDDS in Chile. Material and Methods: Thefactorial structure, internal consistency and test-retest reliability ofthe Spanish-language version of the EDDS was analyzed in a sample of1964 university and high school students. The concurrent validity was tested in a sample of 50 primary care patients with ED and 59 controls, comparing its results with those of a structured psychiatric interview (CIDI). Results: The EDDS showed a high internal consistency, moderate test-retest reliability, an appropriate factorial structure (in women) and an excellent convergent validity. Also, the diagnosis of ED obtained with the EDDS is moderately consistent with the structured psychiatric interview. Conclusions: The Spanish-language version of the EDDS showed a satisfactory psychometric behavior and a good capacity for detecting ED, according to the DSM criterion. HubMed – eating
