Perception definition medical4/7/2023 ![]() The growing epidemic of obesity 8 indicates the need to extend the assessment of body image disturbances to subjects with overweight what may help to prevent the progression to obesity. ![]() It should be noted, that the relationship between body image and body size is not well known among overweight and obese subjects. 7 showed that body dissatisfaction is an important risk factor for the development of eating disturbances in adolescents. In addition, a systematic review performed by Shagar et al. 6 shown that patients with anorexia nervosa demonstrate not only greater differences between their own current and ideal body and body dissatisfaction but also regional perceptual inaccuracy for their own current body than healthy controls. Incorrect assessment of body size in patients with bulimia nervosa and anorexia nervosa were confirmed previously 4, 5. This global term includes subjective, affective, cognitive, behavioural and perceptual processes 3. Women with overweight and obesity more often than men are dissatisfied with their own body size.īody image is conceptualized as a multidimensional construct that includes positive and negative self-perceptions and attitudes (i.e., thoughts, feelings, and behaviours) regarding the body 1, 2. Adults subjects frequently underestimate their own weight status and body size. The degree of body dissatisfaction was greater among women than among men. Normal-weight subjects less often than overweight and obese were dissatisfied with their own body size. There were statistically significant differences in the distribution of body dissatisfaction according to the weight in both women and men. Underestimation of weight status was significantly more common among men than women. Compatibility of self-assessment of weight status with BMI category according to the measured values was moderate-Kappa coefficient was 0.59 (95% CI: 0.54–0.64). Also individuals within the obesity BMI range have rated themselves as normal weight (2.6%), and overweight (41.6%). Individuals within the overweight BMI range have rated themselves as underweight (1.4%), normal weight (30.8%) and obese (2.8%). Participants’ weight and height were measured to calculate body mass index (BMI) after completing the FRS. Additionally, participants’ were asked: ‘Do you think you are: underweight/normal weight/overweight/obese?’ to assess perception of weight status. Body size perception and body dissatisfaction were assessed based on Stunkards’ Figure Rating Scale (FRS). The study included 744 adults (452 women 35.9 ± 12.4 years 21 underweight, 326 normal weight, 221 overweight, 176 obese) referred to Metabolic Management Center and volunteers. Therefore, the study aimed to assess separately the perception of weight status and body size as well as body dissatisfaction in adults with normal weight, overweight and obesity. The effect of self-perception of body size disturbances and body dissatisfaction may be the development of eating disorders, such as anorexia nervosa or binge eating disorder-a major risk factor of obesity development. Self-perception of body size seems to be not always in line with clinical definitions of normal weight, overweight and obesity according to Word Health Organization classification.
