The objectives of the current study, that is the first of its kind, were to determine the prevalence of the hypertriglyceridemic waist (HW) phenotype in a nationally representative sample of children, as well as the metabolic risk factors identified by HW, and to identify lifestyle habits related to this phenotype. This national survey was conducted on 4811 representative school-students. We assessed the sensitivity and specificity of the HW phenotype for abnormal anthropometric and biochemical factors by using receiver operator characteristic curves. We determined the association of dietary patterns (obtained by factor analysis), physical activity level and some environmental factors with the HW phenotype. Overall, 8.52% of participants had the HW phenotype. Those children with the HW phenotype were more likely to have cardiovascular risk factors, notably for overweight and hypercholesterolemia. The dietary pattern characterized by junk foods increased the odds of having the HW phenotype, OR = 1.426 (95%CI, 1.109, 1.892), whereas the other dietary pattern including healthy foods decreased this odds, OR = 0.874 (95%CI, 0.765, 0.998). The risk of the HW phenotype rose with the consumption of solid hydrogenated fat as well as white-flour bread. Low education of parents and a positive family history of diabetes mellitus, obesity and or premature cardiovascular disease were the other risk factors for the HW phenotype. Low levels of physical activity significantly increased the risk of having the HW phenotype. The HW phenotype can be used as an accurate and easy tool for screening children at metabolic risk in population-based studies.

Purpose One anastomosis/mini gastric bypass (OAGB/MGB) is up to date the third most performed obesity and metabolic procedure worldwide, which recently has been endorsed by ASMBS. The main criticisms are the risk of bile reflux, esophageal cancer, and malnutrition. Although IFSO has recognized this procedure, guidance is needed regarding selection criteria. To give clinicians a daily support in performing the right patient selection in OAGB/MGB, the aim of this paper is to generate clinical guidelines based on an expert modified Delphi consensus. Methods A committee of 57 recognized bariatric surgeons from 24 countries created 69 statements. Modified Delphi consensus voting was performed in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was considered to indicate a consensus. Results Consensus was achieved for 56 statements. Remarkably, ≥ 90.0% of the experts felt that OAGB/MGB is an acceptable and suitable option "in patients with Body mass index (BMI) > 70, BMI > 60, BMI > 50 kg/m 2 as a one-stage procedure," "as the second stage of a two-stage bariatric surgery after Sleeve Gastrectomy for BMI > 50 kg/m 2 (instead of BPD/DS)," and "in patients with weight regain after restrictive procedures. No consensus was reached on the statement that OAGB/ MGB is a suitable option in case of resistant Helicobacter pylori. This is likely as there is a concern that this procedure is associated with reflux and its related long-term complications including risk of cancer in the esophagus or stomach. Also no consensus reached on OAGB/MGB as conversional surgery in patients with GERD after restrictive procedures. Consensus for disagreement was predominantly achieved "in case of intestinal metaplasia of the stomach" (74.55%), "in patients with severe Gastro Esophageal Reflux Disease (GERD)(C,D)" (75.44%), "in patients with Barrett's metaplasia" (89.29%), and "in documented insulinoma" (89.47%). Key Points• OAGB/MGB is a suitable option in elderly patients.• OAGB/MGB is a suitable option for patients with low BMI (30-35 kg/m 2 ) with associated metabolic problems.• OAGB/MGB is a suitable option in patients with BMIs more than 50 kg/m 2 as one-stage procedure. OAGB/MGB can be a suitable procedure in patients with large/giant hiatal hernia with concurrent hiatal hernia repair. Extended author information available on the last page of the article ConclusionPatient selection in OAGB/MGB is still a point of discussion among experts. There was consensus that OAGB/ MGB is a suitable option in elderly patients, patients with low BMI (30-35 kg/m 2 ) with associated metabolic problems, and patients with BMIs more than 50 kg/m 2 as one-stage procedure. OAGB/MGB can also be a safe procedure in vegetarian and vegan patients. Although OAGB/MGB can be a suitable procedure in patients with large hiatal hernia with concurrent hiatal hernia, it should not be offered to patients with grade C or D esophagitis or Barrett's metaplasia.

IntroductionThe Isfahan Healthy Heart Programme (IHHP) is a community-based programme for non-communicable diseases prevention and control using both a population and high risk approach in Iran. This study demonstrated the efficacy of IHHP interventional strategies to improve lifestyle behaviours in a population at risk for developing cardiovascular diseases.Material and methodsHealthy Lifestyle for NCDs High Risk Population is one of ten projects of IHHP. High risk individuals were defined as those who have at least one risk factor for developing coronary artery disease (CAD). Changes of behavioural indicators have been compared between two areas with a survey after 5 years of intervention.ResultsAmong high risk individuals in the intervention and reference areas, 77.8% and 82.5% had at least one major risk factor for CAD. The prevalence of major risk factors for CAD (except cigarette smoking) was decreased in both intervention and reference areas during 5 years of intervention and the pattern of diet and physical activity was improved.ConclusionsInterventional activities in IHHP targeting the high risk population seem to be effective in improving lifestyle behaviour, increasing awareness and control of risk factors of the high risk population.
