“…In agreement with other studies worldwide[1,24] and in Iran [7,9,25], our findings show that the prevalences of obesity and abdominal obesity in women are higher than men; gender differences in food intake, physical activity level and psycho-socio-economic status may be responsible for this difference. For example, results of a survey showed that Tehranian women consume more sweets and simple sugars [26].…”

“…In Iran, the prevalence of overweight and obesity in 2005 was reported to be 42.8% in men and 57% in women [7]; for 2015, the figures are predicted to be 54 and 74% respectively [8]. Studies have shown that the prevalence of abdominal obesity to range between 9.7 - 12.9% and 54.5 - 63.7% in Iranian men and women respectively [7,9].…”

BackgroundConsidering the increasing trend of obesity reported in current data, this study was conducted to examine trends of obesity and abdominal obesity among Tehranian adults during a median follow-up of 6.6 years.MethodsHeight and weight of 4402 adults, aged 20 years and over, participants of the Tehran Lipid and Glucose Study (TLGS), were measured in 1999-2001(phase I) and again in 2002-2005(phase II) and 2006-2008 (phase III). Criteria used for obesity and abdominal obesity defined body mass index (BMI) ≥ 30 and waist circumference ≥ 94/80 cm for men/women respectively. Subjects were divided into10-year groups and the prevalence of obesity was compared across sex and age groups.ResultsThe prevalence of obesity was 15.8, 18.6 and 21% in men and 31.5, 37.7 and 38.6% in women in phases I, II and III respectively (p < 0.001). The prevalence of abdominal obesity in men was 36.5, 57.2 and 63.3% and in women was 76.7, 83.8 and 83.6% in the three periods mentioned (p < 0.001). Men aged between 20-29 years had highest increase rates of obesity and abdominal obesity in phase III in comparison with phase I (with a respective rates of 2.2- and 3.3-fold). In both sexes, an increased trend was observed between phases I and II, whereas between phases II and III, this trend was observed in men, but not in women.ConclusionThis study demonstrates alarming rises in the prevalences of both obesity and abdominal obesity in both sexes especially in young men, calling for urgent action to educate people in lifestyle modifications.

“…However, secular changes in increasing overweight/ obesity, especially in women, have been documented in these areas (9) . The present study suggests that while underweight is still the main nutritional problem among young children, it might be replaced by overweight as children grow to adolescence.…”

Objective: The present study examined the prevalence of underweight and overweight in a group of primary-school children in Zahedan, south-east Iran. Design: A cross-sectional study in a randomly selected population of schoolchildren. Setting: Primary-school children in Zahedan city. Subjects: A random sample of 1079 students (boys 5 500 and girls 5 579). Data on child's age, parental educational levels, body weight and height were collected. Results: The rate of overweight/obesity among boys and girls was 8?9 % and 10?3 %, respectively; and of underweight among boys and girls was 22?8 % and 19?9 %, respectively. Prevalence of overweight increased as the boys and girls approached adolescence and it was more prevalent among girls than boys. Prevalence of overweight was directly related to maternal education in this population. Conclusions: High prevalence of underweight in young children as well as increase in the prevalence of overweight in girls and boys near adolescence are of concern. Early poor growth and subsequent rapid weight gain near to adolescent stage is related to adulthood obesity.

“…24 Thus, the high predictive power of WHR for incident CVD in our study population might be attributable to the high prevalence of sedentary lifestyle, especially in females. 25 In the INTER-HEART study, WHR was the strongest anthropometric predictor of myocardial infarction in both genders. 4 The superiority of WHR over WC could be related to HC, as the greater HC is inversely associated with CVD risk.…”

Objective: To determine cutoff points of anthropometric variables for predicting incident cardiovascular disease (CVD) in Iranian adults. Design: It is a population-based longitudinal study. Subjects: A total of 1614 men and 2006 women, aged X40 years, free of CVD at baseline were included in the study. Measurements: Body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and cardiovascular risks were assessed. Incident CVD was ascertained over a median of 7.6 years follow-up. The adjusted hazard ratios (HRs) for CVD were calculated for 1 s.d. change in all obesity variables using Cox proportional hazards regression analysis. Receiver operator characteristic (ROC) curve analysis was used as the method of defining the points of the maximum sum of sensitivity and specificity (MAXss) of each variable as a predictor of CVD. Results: We found 333 CVD events during follow-up. The risk-factor-adjusted HRs were significant for all anthropometric variables in males and WHR in females and were 1.19, 1.24, 1.21 and 1.24 for BMI, WC, WHR and WHtR in males and 1.27 for WHR in females, respectively (all Po0.05). ROC analysis showed the highest area under curve (AUC) for WHR, WHtR and WC, followed by BMI in males and both genders agedp60 years. In females, WHR and WHtR had the highest AUC, followed by WC and BMI. Among those 460 years old, all the anthropometric variables showed same CVD predicting power. The cutoff values (MAXss) for CVD prediction in males and females were BMIs 26.95 and 29.19 kg m À2 ,WCs 94.5 and 94.5 cm, WHRs 0.95 and 0.90, and WHtR 0.55 and 0.62, respectively. Conclusion: There was no difference between central obesity variables in predicting CVD in males, whereas in females WHR and WHtR were more appropriate. The cutoff values of anthropometric variables were higher in the Iranian than in other Asian populations.
