Introduction: The chrono-type, intrinsic to each individual, is the tendency of an individual to prefer activities carried out in the morning or evening. The aim of our study was to determine the chronotype of our obese patients.

Materials and methods: This is a descriptive cross-sectional study involving obese adults consulting the service of Endocrinology of Sfax, Hedi Chaker University Hospital, during the period extending from December 2022 until March 2023. Our patients were subject to the typology questionnaire circadian of Horne and Ostberg.

Results: We recruited 40 obese patients. The average age was 43.47 years×16.56. The sex ratio was 0.21. Fifteen percent of patients were smokers. The average duration of obesity was 20 years ×13.25. The average weight was 95.17 kg. BMI average was 35.96×5.04 kg/m². The average score of Horne’s circadian typology and Ostberg was 55.93×11.28. The chrono-type of our patients was distributed as follows: 5% were very morning, 47% were moderate morning, 32% were neutral, 15% were moderate evening and no patient was entirely in the evening.

Conclusions: Only 15% of patients had an evening chronotype. According to several authors, people with an ‘evening’ chrono-type are more at risk of developing overweight or obesity mechanisms to explain this association are not yet fully elucidated, which must push us to carry out more research on this subject.
