Body Size Misperception and Overweight or Obesity among Saudi College-Aged Females

The aim of the study was to investigate the associations between perceived and desired body size and overweight and obesity among college-aged females. A multistage stratified cluster random sample was used to select 907 healthy females from a major Saudi public university. The Stunkard Figure Rating Scale (FRS) was used for body size assessment. Overweight/obesity classification was based on RMI less than or equal to/greater than 25kg/m(2) Overweight plus obesity prevalence was 28.1%. There were significant differences between females with overweight/obesity and those without overweight/obesity in both perceived and desired body size scores. Compared with only 4% of females without overweight/obesity, 37% of the participants with overweight/obesity scored higher than five (median) in the FRS. The perceived body size correlated more strongly with many of the selected variables than did the desired body size, especially with RMI (r = 0.679; p < 0.001), body weight (r = 0.652; p < 0.001), and weight loss attempts (r = 0.466; p < 0.001). Also, there was a significant relationship between RMI and weight loss attempts (r = 0.370; p < 0.001). BMI and weight loss attempts appear to predict the perceived body size and the discrepancy between perceived and desired body size scores. Psychosocial and lifestyle factors that might influence female's body misperception need to be addressed in future studies.
