Psychosocial Predictors of Weight Loss and Quality of Life at 1 Year Post-Bariatric Surgery: A Cohort Study.

Background: Psychosocial factors, identified in pre-bariatric surgery evaluation, may affect surgical outcomes, as well as defer surgery, making it important to identify psychosocial predictors of surgery outcomes.

Methods: Baseline depressive and social anxiety symptom scores were analyzed as predictors of post-surgical weight loss (WL) and quality of life (QOL) following Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB). Eighty-nine (82F, 7M) participants underwent surgery and completed depression, anxiety and QOL questionnaires 3-weeks pre-surgery and 1-year post-surgery.

Is night eating syndrome associated with obstructive sleep apnea, BMI, and depressed mood in patients from a sleep laboratory study?

Purpose: The aim of this study was to assess night eating syndrome (NES) in patients referred for polysomnography and its association with obstructive sleep apnea (OSA). We also assessed whether participants with OSA were more likely to get up and eat at night, and whether these behaviors were associated with the apnea-hypopnea sleep index (AHI). We additionally examined whether NES and OSA were associated with BMI, and assessed depressed mood among participants with NES or OSA.

Epicatechin, procyanidins, cocoa, and appetite: a randomized controlled trial.

Background: In 2 randomized controlled trials, it was reported that dark chocolate acutely decreased appetite in human subjects, but the authors did not assess the types or concentrations of cocoa compounds that are needed. Other studies have suggested that the cocoa compounds epicatechin and procyanidins may be involved.

Objective: We sought to test the hypotheses that, compared with placebo (an alkalized cocoa mixture containing essentially no epicatechin or procyanidins), the following beverages cause a decrease in appetite: 1) a nonalkalized cocoa mixture; 2) epicatechin plus placebo; and 3) procyanidins plus placebo.
