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 BMI less than or equal to/greater than 25 kg/m. 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 BMI (=0.679; < 0.001), body weight (=0.652; < 0.001), and weight loss attempts (=0.466; < 0.001). Also, there was a significant relationship between BMI and weight loss attempts (=0.370; < 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.
该研究的目的是调查大学适龄女性中感知到的和期望的体型与超重及肥胖之间的关联。采用多阶段分层整群随机抽样方法，从沙特一所主要的公立大学中选取了907名健康女性。使用斯图卡德体型评定量表（FRS）进行体型评估。超重/肥胖分类基于体重指数（BMI）小于或等于/大于25kg/m²。超重加肥胖的患病率为28.1%。超重/肥胖女性与非超重/肥胖女性在感知到的和期望的体型得分上均存在显著差异。在FRS中，超重/肥胖参与者中有37%的得分高于五分（中位数），而未超重/肥胖的女性中只有4%得分如此。与期望的体型相比，感知到的体型与许多选定变量的相关性更强，尤其是与BMI（=0.679；P<0.001）、体重（=0.652；P<0.001）和减肥尝试次数（=0.466；P<0.001）。此外，BMI与减肥尝试次数之间存在显著关系（=0.370；P<0.001）。BMI和减肥尝试次数似乎可以预测感知到的体型以及感知到的和期望的体型得分之间的差异。未来的研究需要探讨可能影响女性身体认知偏差的心理社会和生活方式因素。
