Abstract

Body perception is an individual's ability to recognize their body in attitudinal and/or dimensional aspects. We investigated women's body perceptions before and after bariatric surgery. Participants were 31 women ( age = 36.23, = 7.95 years old) with an average pre-operative body mass index of 44.58 ( = 4.65) kg/m. We collected anthropometric and body perception measures (attitudinal body image [ABI] and dimensional body image [DBI]) before bariatric surgery and 30, 60, 90, and 120 days after it. There was an average decrease of 21.09% in participants' body weight over the 120 days. Regarding ABI, 51.61% of participants had high body dissatisfaction before surgery, and this proportion of dissatisfied participants decreased to 3.23% 120 days after surgery. We observed no statistically significant differences in DBI perceptions. Fast weight loss caused by bariatric surgery appeared to generate a perception of ghost fat. Somatosensory interventions and/or a longer follow-up are needed to alter this persistent distortion of body dimensions.

摘要

身体感知是个体在态度和/或维度方面识别自身身体的能力。我们调查了减肥手术前后女性的身体感知情况。参与者为31名女性（年龄 = 36.23岁，标准差 = 7.95岁），术前平均体重指数为44.58（标准差 = 4.65）kg/m²。我们在减肥手术前以及术后30、60、90和120天收集了人体测量和身体感知指标（态度性身体意象[ABI]和维度性身体意象[DBI]）。在120天内，参与者的体重平均下降了21.09%。关于ABI，51.61%的参与者在手术前身体不满意程度较高，而术后120天，这一不满意参与者的比例降至3.23%。我们观察到DBI感知方面没有统计学上的显著差异。减肥手术导致的快速体重减轻似乎产生了“幽灵脂肪”的感觉。需要体感干预和/或更长时间的随访来改变这种持续的身体维度扭曲。
