BACKGROUND Bioelectrical impedance analysis (BIA) is a safe and easy method of assessing body composition. Its accuracy to predict fat mass (FM) in obesity and the change in FM following weight loss is questioned. Our objective was to compare leg-to-leg BIA to dual-energy X-ray absorptiometry (DXA) in the assessment of FM in a large population, the changes(More)
In recent years, the recourse to obesity surgery to treat morbid obesities has grown. The number of "malabsorptive" interventions, such as the gastric bypass (RYGB: Roux-en-Y gastric bypass) increases each year. The RYGB, which combines two mechanisms promoting weight loss, restriction and malabsorption, has proven its effectiveness in term of weight loss(More)
AIM Dynamics of improvement in health-related quality of life (QoL) after bariatric surgery have never been fully assessed, and neither has the potential influence of body mass index (BMI) and comorbidity modification. The objective of this study was to investigate early and medium-term changes in QoL following Roux-en-Y gastric bypass (RYGB), and their(More)
BACKGROUND The prevalence of overweight and obesity is increasing dramatically worldwide. As a consequence, bariatric surgery for morbid obesity is in constant development. Although bariatric surgery has proven its efficiency at achieving weight loss and correcting comorbidities, it may cause vitamin deficiencies and subsequent complications. The goal of(More)
BACKGROUND Patients scheduled for bariatric surgery (BS) are encouraged to chew slowly in order to optimise the digestion process. The influence of dental status on patients' ability to comply with advice on chewing behaviour is poorly documented. This study aims to compare modifications of chewing function before and after BS in three groups of obese(More)
Epidemiological data indicate an association between periodontitis and obesity. The biological mechanisms of this relationship remain unclear. A cross-sectional study was conducted to evaluate the relationship between periodontitis and the common systemic inflammatory markers in 32 morbidly obese patients recruited in a Clinical Nutrition department.(More)
Little is known on patterns of change over time in body composition, especially lean body mass (LBM), during massive weight loss after Roux-en-Y gastric bypass (RYGB) in obese patients. We performed sequential measurements of total and regional body composition in patients after RYGB, and we compared a subsample of patients after surgery to a nonsurgical(More)
Physical activity is a cornerstone in the medical management of obesity and could be important for weight loss following bariatric surgery. This review aims to describe the evolution of physical activity following massive weight loss induced by bariatric surgery, and to identify the relationship between physical activity and amount of weight loss. A(More)
There are numerous beneficial effects of physical activity for diabetes mellitus treatment and prevention. Irrespective of diet or weight loss, exercise training reduces HbA1c by an amount that should reduce diabetic complications, improves cardiorespiratory fitness that is a predictor of mortality, and improves body composition. Endurance training is(More)
AIM To identify changes in the salivary protein/peptide profiles by differential proteomics in obese patients with or without periodontitis. MATERIAL AND METHODS Periodontal examinations and whole saliva samples were obtained from 38 obese patients (mean age: 45.1 ± 7.3 years, mean BMI: 49.3 ± 9 kg/m(2) ) including 13 periodontitis and 25(More)
