BACKGROUND: The Eating Disorder Examination-Questionnaire (EDE-Q) is increasingly used in studies with bariatric surgery patients although little is known about psychometric properties of this self-report measure in this clinical group. The current study evaluated the factor structure and construct validity of the EDE-Q in bariatric surgery candidates. METHODS: Participants were a consecutive series of 174 obese bariatric surgery candidates who completed the EDE-Q and a battery of behavioral and psychological measures. RESULTS: Confirmatory factor analysis (CFA) revealed an inadequate fit for the original EDE-Q structure but revealed a good fit for an alternative structure suggested by recent research with obese samples. CFA supported a seven-item, three-factor structure; the three factors were interpreted as dietary restraint, shape/weight overvaluation, and body dissatisfaction. The three factors converged with other relevant collateral measures. CONCLUSIONS: These factor analytic findings, which replicate recent findings from studies with diverse obese samples, demonstrated convergent validity. Implications of these findings for clinical assessment and research with bariatric surgery patients are discussed.

OBJECTIVE To investigate the association between overeating (without loss of control) and binge eating (overeating with loss of control) and adverse outcomes. DESIGN Prospective cohort study. SETTING Adolescents and young adults living throughout the United States. PARTICIPANTS Sixteen thousand eight hundred eighty-two males and females participating in the Growing Up Today Study who were 9 to 15 years old at enrollment in 1996. MAIN EXPOSURE Overeating and binge eating assessed via questionnaire every 12 to 24 months between 1996 and 2005. MAIN OUTCOME MEASURES Risk of becoming overweight or obese, starting to binge drink frequently, starting to use marijuana, starting to use other drugs, and developing high levels of depressive symptoms. Generalized estimating equations were used to estimate associations. All models controlled for age and sex; additional covariates varied by outcome. RESULTS Among this large cohort of adolescents and young adults, binge eating was more common among females than males. In fully adjusted models, binge eating, but not overeating, was associated with incident overweight/obesity (odds ratio, 1.73; 95% CI, 1.11-2.69) and the onset of high depressive symptoms (odds ratio, 2.19; 95% CI, 1.40-3.45). Neither overeating nor binge eating was associated with starting to binge drink frequently, while both overeating and binge eating predicted starting to use marijuana and other drugs. CONCLUSIONS Although any overeating, with or without loss of control, predicted the onset of marijuana and other drug use, we found that binge eating is uniquely predictive of incident overweight/obesity and the onset of high depressive symptoms. These findings suggest that loss of control is an important indicator of severity of overeating episodes.

The effects of weight cycling on lifespan in male C57BL/6J mice.

Objective:With the increasing rates of obesity, many people diet in an attempt to lose weight. As weight loss is seldom maintained in a single effort, weight cycling is a common occurrence. Unfortunately, reports from clinical studies that have attempted to determine the effect of weight cycling on mortality are in disagreement, and to date, no controlled animal study has been performed to assess the impact of weight cycling on longevity. Therefore, our objective was to determine whether weight cycling altered lifespan in mice that experienced repeated weight gain and weight loss throughout their lives.Methods:Male C57BL/6J mice were placed on one of three lifelong diets: a low-fat (LF) diet, a high-fat (HF) diet or a cycled diet in which the mice alternated between 4 weeks on the LF diet and 4 weeks on the HF diet. Body weight, body composition, several blood parameters and lifespan were assessed.Results:Cycling between the HF and LF diet resulted in large fluctuations in body weight and fat mass. These gains and losses corresponded to significant increases and decreases, respectively, in leptin, resistin, GIP, IGF-1, glucose, insulin and glucose tolerance. Surprisingly, weight cycled mice had no significant difference in lifespan (801±45 days) as compared to LF-fed controls (828±74 days), despite being overweight and eating a HF diet for half of their lives. In contrast, the HF-fed group experienced a significant decrease in lifespan (544±73 days) compared with LF-fed controls and cycled mice.Conclusions:This is the first controlled mouse study to demonstrate the effect of lifelong weight cycling on longevity. The act of repeatedly gaining and losing weight, in itself, did not decrease lifespan and was more beneficial than remaining obese.International Journal of Obesity advance online publication, 11 December 2012; doi:10.1038/ijo.2012.203.

Littlest Pet Shop: Popular (Episode #16: The Fallout – Season Finale Part 1/2) [CC FRANÇAIS] – Paws, claws, and insults will be flying. Dogs and cats alike will be crying. Nothing good will come to those caught lying. It’s about to go down in the season 1 finale of LPS: Popular. The truth will be revealed as ugly secrets from the past are resurrected. Tales of clandestine meetings, secret relationships and incriminating videos will come to light, and carefully wrought plans will burst apart at the seams. Run all you want… but there’s no hiding your secrets. ***This video uses the words “tramp” and “floozy,” both words for an immoral/disloyal woman. Of all the offensive words in the English language, I hardly think these are “swear words,” but if you’re offended by them, maybe you shouldn’t watch this video. I would like to point out, however, that there is a Disney movie called Lady and the Tramp, so it really can’t be bad! But since some of my viewers have been offended by the word “crap,” I thought I should add this warning just in case. :)*** THANK YOU to PetShopZapping for taking the time to make French subtitles for me! / UN GRAND MERCI à PetShopZapping pour avoir pris le temps de crée des sous-titres en français! youtube.com VERY IMPORTANT WARNING: The Popular series is rated PG. Although these videos are made with Littlest Pet Shop toys, the Popular series is NOT meant for very young children and is geared more towards preteens. This story is set in a high school and thus explores themes that are definitely more mature (but not too mature, don’t worry …
