BACKGROUND A correct perception of the body image, as defined by comparison with actual anthropometric analyses, is crucial to ensure the best possible nutritional status of each individual. Bioimpedance analysis (BIA) represents a leading technique to assess body composition parameters and, in particular, the fat mass. This study examined the self-perception of body image at various levels of adiposity proposing a new index. METHODS We investigated 487 young Italian adults (mean age of males: 21.9 ± 2.4 years; mean age of females: 21.0 ± 2.2 years). Each subject could choose, on the Contour Drawing Rating Scale, the silhouette that he/she considered most resembling his/her perceived body image as well as his/her ideal body image. On each subject, we performed anthropometric measurements and determined the values of Fat mass and %Fat with BIA. A new index, FAIFAT (Feel fat status minus Actual fat status Inconsistency), was developed to evaluate possible fat status perception inconsistencies by BIA. RESULTS Based on ideal and feel body image comparison, women showed higher dissatisfaction than men and preferred slimmer silhouettes. FAIFAT values indicated that the fat status perception was correct in the majority of the examined individuals and only three subjects showed a serious misperception. CONCLUSIONS Our findings suggest that FAIFAT is an appropriate index for assessing the perceived fat status from the body image when compared with data obtained by BIA. In a population, the use of this index will allow the correct identification of groups at risk for eating disorders.

身体形象感知和身体组成:通过新指标评估感知不一致。

背景技术通过与实际人体测量学分析相比较定义的对身体图像的正确感知对于确保每个人的最佳营养状态至关重要。生物阻抗分析(BIA)代表了一种领先的技术,可以评估人体成分参数,尤其是脂肪量。这项研究在各种肥胖水平上研究了对身体图像的自我感知,提出了一个新的指标。方法我们调查了487位意大利年轻人(男性平均年龄:21.9±2.4岁;女性平均年龄:21.0±2.2岁)。每个受试者都可以在等高线图评分量表上选择他/她认为最类似于他/她感知的身体图像以及他/她理想的身体图像的轮廓。我们对每个受试者进行了人体测量,并确定了BIA的脂肪质量和%脂肪的值。开发了一种新的指数FAIFAT(感觉脂肪状况减去实际脂肪状况不一致),以评估BIA可能出现的脂肪状况感知不一致。结果基于理想和感觉身体形象的比较,女性表现出比男性更高的不满和偏爱的苗条身材。FAIFAT值表明,在大多数接受检查的个体中,脂肪状况的感知是正确的,只有三名受试者表现出严重的误解。结论我们的发现表明,与BIA获得的数据相比,FAIFAT是评估人体图像中脂肪状态的合适指标。在人群中,使用该指数可以正确识别有饮食失调风险的人群。被开发用于评估BIA可能的脂肪状况知觉不一致。结果基于理想和感觉身体形象的比较,女性表现出比男性更高的不满和偏爱的苗条身材。FAIFAT值表明,在大多数接受检查的个体中,脂肪状况的感知是正确的,只有三名受试者表现出严重的误解。结论我们的研究结果表明,与BIA获得的数据相比,FAIFAT是评估人体图像中脂肪状态的合适指标。在人群中,使用该指数可以正确识别有饮食失调风险的人群。被开发用于评估BIA可能的脂肪状况知觉不一致。结果基于理想和感觉身体形象的比较,女性表现出比男性更高的不满和偏爱的苗条身材。FAIFAT值表明,在大多数接受检查的个体中,脂肪状况的感知是正确的,只有三名受试者表现出严重的误解。结论我们的发现表明,与BIA获得的数据相比,FAIFAT是评估人体图像中脂肪状态的合适指标。在人群中,使用该指数可以正确识别有饮食失调风险的人群。FAIFAT值表明,在大多数接受检查的个体中,脂肪状况的感知是正确的,只有三名受试者表现出严重的误解。结论我们的研究结果表明,与BIA获得的数据相比,FAIFAT是评估人体图像中脂肪状态的合适指标。在人群中,使用该指数可以正确识别有饮食失调风险的人群。FAIFAT值表明,在大多数接受检查的个体中,脂肪状况的感知是正确的,只有三名受试者表现出严重的误解。结论我们的研究结果表明,与BIA获得的数据相比,FAIFAT是评估人体图像中脂肪状态的合适指标。在人群中,使用该指数可以正确识别有饮食失调风险的人群。
