There is an obesity epidemic worldwide, which has been increasing in recent years. An epidemiologic cross-sectional study was conducted among 3799 persons who were 30–70 years old in Semnan Province, Iran. Multistage cluster sampling was performed, and subjects were selected from urban and rural populations. Body weight, height and waist circumference (WC) were measured, and body mass index (BMI) and waist to hip ratio (WHR) were calculated. Overweight and obesity were defined as 25 ≤ BMI < 30 and ≥30 respectively in men with WHR ≥ 0.9 or WC ≥ 102 cm, and women with WHR ≥ 0.8 or WC ≥ 88 cm were considered centrally obesite. Prevalence of obesity and overweight was 26.3% and 40.6% respectively. Prevalence of obesity was more among women (39.5%) than men (14.5%) with central obesity prevalence using WHR and WC cut-points of 72.2% and 26.6% respectively. There was a significant association between obesity and age, gender, residential area and educational level ( P < 0.01). In conclusion, prevalence of obesity and overweight among 30–70 years old, especially among women, was higher than expected. A comprehensive educational programme on obesity risk factors and obesity-related diseases is necessary. [ABSTRACT FROM AUTHOR]

Aim: To compare the ability of anthropometric indices [waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), neck-to-height ratio (NHR), conicity index (CI), body adiposity index (BAI), tri-ponderal mass index (TMI) and body mass index (BMI)] and,measuerments like neck(NC), hip(HC) and waist circumferences to predict overweight and obesity in Iranian preschool children., Materials and Methods: A total of 498 Iranian preschool children were included in this case-control study conducted in Tehran, Iran. The participants were selected using the stratified random sampling procedure based on gender and school. Using sex-based receiver operating curve (ROC) analysis, we compared the area under the curve and defined the cut-off points for detecting central and general obesity for each index in order to identify the most suitable tools in predicting obesity., Results: Boys had significantly higher values for NC, WC, WHR, NHR, CI, TMI and BMI as compared to girls, whereas BAI and HC were higher in girls. The area under the curve was calculated for all the possible predictors of central obesity, i.e., NC (0.841-0.860), WC (0.70-0.679), HC (0.785-0.697), WHR (0.446-0.639) and CI (0.773-0.653) in boys and girls, respectively. And according to the ROC curve analysis, BMI (0.959-0.948), TMI (0.988-0.981), WHtR (0.667-0.553) and NHR (0.785-0.769) were predictors of general obesity and NC (0.841-0.860) as predictor of central obesity in boys and girls, respectively. The optimal cut-off points for TMI (13.80-15.83), NC (28.68-27.5) and for other anthropometric indices were estimated in both boys and girls., Conclusion: TMI and NC seem to predict general and central obesity in Iranian preschool children., (© 2022.

Background: Several abdominal obesity measures have been used for prediction of 10-year cardiovascular disease (CVD) risk but the superiority of these measures remains controversial. The objective of this study was to assess the predictive ability of abdominal obesity measures for risk of CVD events in an Iranian adult population., Methods: We analyzed the data of population based cross-section study of 567 representative samples of adult population aged 40-70 years in Babol, the north of Iran. The demographic data, the anthropometric measures, lipid profile and cardiometabolic risk factors were measured with standard methods. Waist to hip ratio (WHR), waist to height ratio (WHtR), conicity index(CI), abdominal volume index (AVI) and body mass index(BMI)were calculated. The individual 10-year CVD risk was estimated based on ACC/AHA model. ROC analysis was performed to assess the diagnostic ability of different abdominal obesity measures and body mass index (BMI) in predicting of high risk of CVD events., Results: About 42.5% of men and 15% of women had at least 10% risk of 10-year cardiovascular events and 21.1% of men and 3.0% of women had ≥20% risk. Except WHR for men, all abdominal obesity measures significant predictors for ≥10% risk CVD risk in both sexes but not BMI. The greater ability of CVD risk prediction was observed by WHtR and CI in both sexes with higher AUC in females compared with men for ≥10% risk., Conclusion: WHtR and CI are superior indexes in predicting of high risk of CVD events in both sexes., (Copyright © 2018 Diabetes India.
