Introduction: Misperception of body weight and lack of awareness about overweight and obesity are associated with poor weight management behaviors.Materials and Methods: This cross-sectional study included 350 female students from Shahed University, Tehran, Iran, using a convenience sampling method. Data were collected through anthropometric measurements and self-reported answers regarding weight perception and level of body weight preoccupation. Data analysis was conducted using Spearman’s rank correlation coefficient.Results: The findings revealed that 51.43% of the subjects misperceived their body weight. Among them, the majority (92.22%) underestimated their weight. Additionally, 17.14% of the overweight and obese subjects perceived their weight to be within the normal range, while 29.6% of obese subjects perceived themselves to be only slightly overweight. Furthermore, there was a significant relationship between body weight perception and anthropometric indices (p<0.01). The body mass index (r=0.739), C-index (r=0.648), body adiposity index (r=0.620), abdominal volume index (r=0.552), and waist-to-height ratio (r=0.537), and waist circumference (r=0.533) had the highest correlation with body weight perception, respectively.Conclusion: The high rate of unawareness of actual body weight among female university students is alarming. It is, therefore, necessary to develop programs that increase awareness about normal body weight and the importance of anthropometric indices in weight management.

AbstractBackground: Physical activity and exercise along with nutrition and hygiene, are major factors in prevention of diseases. Due to increase in pulmonary disease prevalence in recent decades and the role of oxidative stress in the pathogenesis of these diseases, the purpose of this study was to determine the effect of a period swimming exercise on Sirtuin 1 (Sirt1) and Forkhead box O3 (FoxO3a) genes expression in lung tissue of wistar rats. Materials and Methods: Twenty wistar rats with the weight of 102 ± 23 g randomly divided into two groups: exercise (n=10) and control (n=10). The exercise protocol included three months of swimming exercise (5 times per week) which begun from 25 minutes in the first week (4 liters per minute) and reached to 60 minutes (10 liters per minute) in the final week. Real time- PCR method was used to assess the genes expression of Sirt1 and FoxO3a in lung tissue. Kolmogorov-Smirnov test was used to test the normality and Independent t test was used to compare the group (α
