Background Waist circumference has been suggested as predictor for metabolic syndrome (MetS) in adolescents but it has not been compared with newly proposed anthropometric indexes. This study aimed to disclose the capacity of ten classic and novel anthropometric indexes to discriminate by the presence of MetS in this young population. Materials and methods A cross‐sectional study was performed on 981 adolescents (13.2 ± 1.2 years) randomly recruited from eighteen schools in south‐east Spain. Body fat percentage (BF%), abdominal volume index (AVI), body roundness index (BRI), body mass index (BMI), body adiposity index (BAI), body adiposity index for paediatrics (BAIp), conicity index (C‐Index), waist circumference (WC), waist‐to‐hip ratio (WHR), waist‐to‐height ratio (WHtR) and body shape index (ABSI) were measured and calculated. Receiver‐operator curves (ROC) were created to determine the discriminatory capacity of these anthropometric parameters for MetS. Results The prevalence of MetS was 7.0% for boys and 6.1% in girls. Participants with MetS had significantly higher levels of blood pressure and plasma levels of lipids, glucose and insulin. All anthropometric indexes were elevated in MetS individuals compared to the non‐MetS group. AVI and WC showed the highest AUC values (0.83 for boys and 0.86 for girls). In contrast, according to ROC analyses, no anthropometric index was capable of discriminating the components of MetS (hypertension, hypertriglyceridemia, hyperglycaemia and low‐HDL levels), except for abdominal obesity. Conclusion We suggest the use of WC and AVI, with the cut‐off points presented herein, for the discrimination between adolescents with or without MetS.

We previously reported, using the diagnostic criteria of the International Diabetes Federation (IDF), that waist circumference (WC) and abdominal volume index (AVI) were capable of predicting metabolic syndrome (MetS) in adolescents. This study was aimed at confirming this finding when other diagnostic criteria are used. A cross-sectional study was performed on 981 Spanish adolescents (13.2 ± 1.2 years). MetS was diagnosed by eight different criteria. Ten anthropometric indexes were calculated and receiver-operator curves (ROC) were created to determine their discriminatory capacity for MetS. Of all diagnostic criteria, the ones proposed by the IDF showed the highest mean values for weight, WC and systolic blood pressure in boys and girls with MetS, and the lowest for glucose and triglycerides in boys. ROC analysis showed that only WC, AVI and body roundness index (BRI) achieved area under the curve (AUC) values above 0.8 in boys, and that fat content, body mass index (BMI), WC, AVI, BRI and pediatric body adiposity index (BAIp) showed AUC values above 0.8 in girls. Importantly, this occurred only when diagnosis was carried out using the IDF criteria. We confirm that WC and AVI can predict MetS in adolescents but only when the IDF’s diagnostic criteria are employed.

The high prevalence of obesity is a serious public health problem in today’s world. Both obesity and insulin resistance favor the development of metabolic syndrome (MetS), which is associated with a number of pathologies, especially type 2 diabetes mellitus, and cardiovascular diseases. This serious problem highlights the need to search for new natural compounds to be employed in therapeutic and preventive strategies, such as oleanolic acid (OA). This research aimed to systematically review the effects of OA on the main components of MetS as well as oxidative stress in clinical trials and experimental animal studies. Databases searched included PubMed, Medline, Web of Science, Scopus, EMBASE, Cochrane, and CINAHL from 2013 to 2019. Thus, both animal studies (n = 23) and human clinical trials (n = 1) were included in our review to assess the effects of OA formulations on parameters concerning insulin resistance and the MetS components. The methodological quality assessment was performed through using the SYRCLE’s Risk of Bias for animal studies and the Jadad scale. According to the studies in our review, OA improves blood pressure levels, hypertriglyceridemia, hyperglycemia, oxidative stress, and insulin resistance. Although there is scientific evidence that OA has beneficial effects in the prevention and treatment of MetS and insulin resistance, more experimental studies and randomized clinical trials are needed to guarantee its effectiveness.

Background: Debriefing is the reflective process following the simulation experience. We aimed to compare the debriefing assessment and debriefing satisfaction perceived by nursing students who underwent different debriefing methods. Method: An experimental study conducted on three groups (instructor-led debriefing, peer debriefing, and combined debriefing) was performed for 177 nursing students. Differences in the debriefing satisfaction were assessed using the Clinical Experience Simulation scale, the Visual Analogue scale, and the Debriefing Assessment for Simulation in Healthcare (DASH). Results: VAS scores for satisfaction differed significantly between the instructor-led debriefing, peer debriefing, and combined debriefing groups. In the Clinical Experience Simulation scale, the combined debriefing group was significantly higher compared with instructor-led debriefing. The total score for DASH was significantly higher in the combined debriefing group compared with instructor-led debriefing, and in instructor-led debriefing compared with peer debriefing. Conclusion: Combining debriefing after a simulation session improves the debriefing satisfaction and the perceived debriefing assessment among nursing students. [ J Nurs Educ . 2021;60(2):90–95.]
