ABSTRACT

Objective: this study had the purpose of knowing the association of the body mass index and cardiovascular regulation of medical students. Materials and methods: a cross-sectional study with a randomized design. The sample consisted of 54 medical students (21,2 ± 1,6 years) who were evaluated and classified according to the body mass index: Normal weight (NP; BMI Keywords: body composition; heart rate; blood pressure; medical students.25 kg / m2); Overweight (SP; BMI≥ 25 kg / m2); Obese (OB; BMI ≥ 30 Kg / m2). Anthropometric measurements, blood pressure, and heart rate variability (HRV) were the variables evaluated. Results: 51,9% of the students are overweight or obese. The body mass index was negatively correlated with the heart rate variability parameter, especially when compared with the HRV time domains (p ‹0.001). Differences were also observed in cardiac autonomic control when comparing the study groups in LnRMSSD (p ‹0,01) and LnSDNN (p ‹0,01). Conclusion: the implementation of measures that decrease BMI values will allow greater autonomic cardiac control and better cardiovascular health in medical students.
