Body-size estimation by obese subjects

Area of Science:

• Psychology
• Body Image Research
• Obesity Studies

Background:

• Body image perception is crucial in weight management and psychological well-being.
• Understanding how obese individuals perceive their bodies is vital for effective treatment.
• Previous research indicates discrepancies between perceived and actual body size in various populations.

Purpose of the Study:

• To investigate and compare body-image perception between hospitalized obese subjects undergoing weight loss and normal-weight individuals.
• To analyze the perception of specific body areas (head, thoracic, abdominal, pelvic) in relation to actual body dimensions.

Main Methods:

• Utilized the 1978 modified Askevold perception test (Allamani et al.) for nonverbal body dimension evaluation.
• Employed custom software (AREA.BASIC2) to calculate perceived and actual body areas.
• Analyzed percentage deviation index [(perceived area/real area) x 100] for statistical comparison.

Main Results:

• Obese subjects demonstrated a significant underestimation of all four measured body areas (head, thoracic, abdominal, pelvic).
• In contrast, normal-weight individuals tended to overestimate their abdominal and pelvic areas.
• A notable difference in body perception was observed between the obese and normal-weight groups.

Conclusions:

• Obese individuals undergoing weight loss treatment exhibit altered body-image perception, characterized by underestimation of body size.
• Normal-weight individuals show a tendency towards overestimation in specific areas, suggesting different perceptual patterns.
• These findings underscore the importance of addressing body image in obesity treatment and highlight distinct perceptual differences between obese and normal-weight populations.
