RESUMO
BACKGROUND: Cardiorespiratory function is one of the key health indicators that promote good health. Knowing the correlation between body mass index (BMI) and cardiorespiratory functioning might assist in the creation of evidence-based therapies that focus on addressing difficulties associated with obesity. OBJECTIVE: To assess the correlation between BMI and cardiorespiratory functions among medical students at Northern Border University. MATERIALS AND METHODS: A cross-sectional study was conducted among medical students at Northern Border University, Saudi Arabia. The blood pressure (BP), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), pulse pressure (PP), and BMI of the students were measured. RESULTS: The mean age of the students was 17.1 ± 1.9 years. Nearly 40% of students were overweight or obese. Our study revealed a significant positive correlation between BMI and BP, RR, tidal volume (TV), and MAP. CONCLUSIONS: The correlation analysis of our study revealed a significant positive correlation of BMI with BP, RR, TV, and MAP.
