PURPOSE
The purpose of this study was to examine the differences among actual body size, perceived body size, and ideal body size in overweight and obese young adult women.
METHODS
Actual body size was assessed by body mass index (BMI), while self-perceived and ideal body sizes were assessed by the Body image assessment tool-body dimension. Descriptive statistics were calculated and analysis of variance (ANOVA) was performed on actual BMI as a function of perceived BMI.
RESULTS
Of the 42 participants included in the study, 12 were overweight (25 ≤ BMI < 30), 18 were obese 1 (30 ≤ BMI < 35), and 12 were obese 2 (35 ≤ BMI ≤ 39.48). The mean ideal body size of participants was 25.34 ± 1.33. Participants in general perceived their body size (BMI: 35.82 ± 1.06) to be higher than their actual body size (32.84 ± 0.95). Overweight participants had a significantly higher mean body size misperception than obese 2 individuals (µ dif = -6.68, p < .001).
CONCLUSION
Perception accuracy of body size differs in women by BMI. Weight loss programs need to be tailored to consider body size misperception in order to improve treatment outcomes for overweight and obese young women.
目的
本研究旨在探讨超重及肥胖的年轻成年女性在实际体型、感知体型和理想体型方面的差异。
方法
通过体重指数（BMI）评估实际体型，同时使用身体形象评估工具—身体维度来评估自我感知体型和理想体型。计算描述性统计量，并对实际BMI作为感知BMI的函数进行方差分析（ANOVA）。
结果
在纳入研究的42名参与者中，12人超重（25≤BMI＜30），18人肥胖1级（30≤BMI＜35），12人肥胖2级（35≤BMI≤39.48）。参与者的平均理想体型为25.34±1.33。总体而言，参与者感知到的自己的体型（BMI：35.82±1.06）高于其实际体型（32.84±0.95）。超重参与者的平均体型误判显著高于肥胖2级个体（μ差值=-6.68，p＜0.001）。
结论
女性对体型的感知准确性因BMI而异。减肥计划需要根据体型误判情况进行调整，以改善超重及肥胖年轻女性的治疗效果。
