Introduction:

Nowadays, there are health and lifestyle problems related to overweight. These conditions have repercussions on the poor quality of sleep and rest, thus affecting people's performance.

Objective:

To determine the influence of body mass index on the chronotype of teachers of the Corporación Universitaria Autónoma del Cauca.

Methods:

The research was based on the quantitative paradigm. Seventy-seven teachers participated. The Horne-Osberg questionnaire was used to determine the chronotype. Measurements of weight, height, fat percentage, waist circumference and hip circumference were taken.

Results:

The population evaluated was characterized by an intermediate chronotype as early riser and tendency to overweight.

Conclusion:

The incidence of the intermediate chronotype as an early riser indicates that work activity generates changes in the sleep-wakefulness relationship. The relationship between body mass index and chronotype was not visible, but epidemiological control and surveillance actions should continue.
