| Objective To explore the relationship between body shape, body shape cognitive deviation, and pathological slimming behavior among medical students, so as to provide reference for helping medical students establish correct body shape cognition and improve health awareness. Methods Using cluster sampling method, a survey was conducted on 543 students of Anhui Medical University from January to April 2019. Data on height, weight, and waist circumference were collected through physical measurements to evaluate the true body shape of the survey subjects. A questionnaire was used to investigate students' self-evaluation of body shape, body shape cognitive deviation,and pathological slimming behavior. Results The consistency rate between medical students' evaluation of their own body shape and their actual body shape was 56.9%, and the Kappa coefficient of consistency was 0.258(P<0.05). The score of pathological slimming behavior was(8.98±2.95) points. Multiple linear regression analysis showed that the proportion of dietary expenditure, body mass index(BMI), and body shape cognitive deviation could explain 16.5% of the total variation in the degree of pathological slimming behavior. All three variables had a positive predictive effect on pathological slimming behavior(P<0.05). Conclusions The current survival of medicine lies in the issue of body shape cognitive deviation, which is an important factor affecting pathological slimming behavior among medical students. |
