    ABSTRACT: Physical activity (PA) is an important adjunct to bariatric surgery in the treatment of severe obesity; however, patient PA levels prior to and in the short-term following surgery are usually low. Scarce data exist describing PA and sedentary behaviours in the long term following surgery. The objectives were to describe PA and sitting time in bariatric patients 1–16 years post-surgery and assess their associations with patient, surgery and weight-loss characteristics. A total of 398 bariatric patients (73% female; mean age 47 ± 11 years, mean 6 ± 4 years since surgery) completed a telephone questionnaire. Patients reported moderate-to-vigorous PA (MVPA: # sessions week−1 ≥30 min), sitting time (h d−1) and change in PA and sitting time vs. pre-surgery (more/same/less). Associations with patient, surgery and weight-loss characteristics were assessed. Only 53% of patients reported ≥1 session week−1 MVPA, mean sitting time was 7 ± 4 h d−1, 74% of patients reported more PA and 53% reported less sitting, now vs. pre-surgery. Age, sex, smoking status, pre-surgery body mass index, time-since-surgery and percent excess weight lost were significantly associated with PA and/or sitting outcomes. Patients currently experiencing ≥50% excess weight loss had over three times the odds of reporting ≥1 session week−1 MVPA (odds ratio [95% confidence interval] 3.28 [1.57, 6.89]) and almost four times greater odds of reporting ‘more’ PA vs. pre-surgery (3.78 [2.15, 6.62]) compared with their less successful counterparts. Results point to low PA and high sedentariness among bariatric patients in the long-term following surgery, associated with several characteristics. Associations with long-term weight management highlight the need for tailored interventions to promote active living in this patient population.

    ABSTRACT: Background: Surgically induced weight loss is a treatment option for the management of obe-sity and the related common disorders. This study evaluated the beneficial effects of bariatric surgery on metabolic profile and the prevalence of metabolic syndrome (MetS) among Iranian patients. Materials and Methods: A prospective observational study was performed on 26 morbidly obese patients scheduled for bariatric surgery, using laparoscopic Roux-en-Y gastric bypass (LRYGB). The parameters of hypertension, type 2 diabetes mellitus (T2DM), hyperlip-idemia, MetS prevalence, and anthropometric measurements of Iranian patients, were recorded, at the preoperative visit and in follow-ups. The follow-up was performed for a median of 12 months, and the change in MetS prevalence and its componnts were assesed. Results: LRYGB induced a mean weight loss of 69.0±21.2%, after 12 months. Preoperative MetS was diagnosed in 21 patients (84%) and decreased to 6 patients (24%) after LRYGB (P=0.001). Likewise, the prevalence of hypertension was significantly decreased from 76% (pre-LRYGB values) to 20% (post-LRYGB values) (P=0.001). The prevalence of T2DM was also decreased from 20% to 8% (P=0.5).Conclusion: According to our results, RYGB produced a rapid and significant weight loss and improvement in hypertension and MetS within one year but there was a cont roversy about

    ABSTRACT: Surgical intervention in obesity is today the most effective treatment method in high level obesity management. Bariatric interventions not only ensure body weight reduction, but may influence dietary habits. To assess changes in adipose hormones and dietary habits in obese patients after sleeve gastrectomy. The study set comprised 37 subjects (29 females and 8 males) 24 to 68 years old with body mass index 43.0 ±4.9 kg/m(2). Pre-operative examination included baseline measurements of body composition. Dietary habits and intake frequency were monitored by a questionnaire method. Follow-up examinations were carried out in a scope identical to the pre-operative examination, 6 and 12 months after surgery, respectively. The average patient weight loss 12 months after surgery was 31.7 kg. Excess weight loss was 55.2 ±20.6%. Patients reported reduced appetite (p < 0.001), increasingly regular food intake (p < 0.001), intake of more meal portions per day (p = 0.003) and a decrease in consuming the largest portions during the afternoon and evening (p = 0.030). Plasma levels of fasting glucose, leptin and ghrelin significantly decreased (p = 0.006; p = 0.0.043); in contrast, the level of adiponectin significantly increased (p < 0.001). Sleeve gastrectomy and follow-up nutritional therapy resulted in a significant body weight reduction within 1 year after surgery. An improvement of certain dietary habits in patients was registered. At 12 months after surgery, there were no statistically significant differences in decreases in ghrelin and leptin concentrations between patients without changed appetite and those reporting decreased appetite.
