Rationale: Obesity is a major public health problem that is constantly on the increase both nationally and worldwide. The study of eating behaviour in obese patients has been widely reported in the literature, but the relationship between eating behaviour and Body Mass Index (BMI) has not been extensively investigated. The main objective of this study was to describe the eating behaviour of obese patients according to their BMI.

Methods: This was a retrospective, cross-sectional, descriptive and comparative study, including obese patients monitored by the Nutrition Unit of the University Hospital Centre (CHU) of Limoges, from February to April 2019. Eating disorders were screened using the SCOFF-F questionnaire. Statistical analysis was performed using ANOVA, Kruskal-Wallis, Chi2, Fisher and univariate then multivariate logistic regression tests. The threshold of significance was p<0,05.

Results: The median age of the study population was 54 years [40,5 – 62] with a median BMI of 38,3 kg/m² [34,6 – 42,8], with a majority of women (62,6%). There was a significant difference between the 3 BMI classes, particularly for physical activity (p=0,035), SCOFF-F questions relating to loss of control (p=0,031) and food (p=0,008), prandial hyperphagia (p=0,040), and sleeve gastrectomy (p=0,033). There were no significant differences between these groups after adjustment and 2 by 2 analysis. The SCOFF-F question about food was positively associated with an increase in BMI (OR: 2,41 [CI95% 1,18-4,88], p=0,015 for severe obesity and OR:2,80 [CI95% 1,42-5,52], p=0,003, for massive obesity).

Conclusion: The SCOFF-F question relating to food is a factor positively associated with an increase in BMI, particularly for severe and massive obesity compared with moderate obesity. Our study did not reveal any differences between the different grades of obesity in terms of eating behaviour.]
