Abstract
Objective: To examine the correlation between hemodynamic parameters and pulmonary function across different Body Mass Index (BMI) categories.
Methodology: This cross-sectional study involved 180 healthy male and female adults (18-40 years) and all were classified according to WHO BMI categories as underweight (<18.5 kg/m2), normal weight (18.5-24.9), overweight (25-29.9) and obese (≥30). Spirometric variables were measured by a PowerLab system and hemodynamic parameters including pulse rate, systolic and diastolic blood pressure (SBP, DBP), mean arterial pressure (MAP) and pulse pressure were also recorded. Data were analyzed using Pearson's correlation using IBM SPSS version 27.
Results: Significant positive correlations between pulse pressure and FVC (r = 0.368, p=0.032) and FEV1 (r = 0.389, p=0.023) were found, and a positive correlation between SBP and FEV1 (r = 0.340, p=0.049) in the underweight group. Pulse pressure had a negative relationship with mean VT in normal weight group (r = -0.319, p=0.042. FVC, FEV1, VT and IRV, IC, VC and TLC had a positive correlation with SBP (all p<0.05), whereas ERV was negatively correlated with SBP (r =-0.326, p=0.013). Pulse was positively related to VT in the obese group (r=0.289, p=0.049) and IC (r=0.331, p=0.023), MAP was negatively related to ERV (r= -0.290, p=0.048), and DBP was negatively related to FVC (r= -0.325, p=0.026).
Conclusion: Each BMI category displays unique relationships between pulmonary function and hemodynamic parameters. Changes in cardiopulmonary relationships with increasing adiposity suggest BMI-specific physiological adaptations.

Key words: Healthy young adults, spirometry, hemodynamic parameters, BMI categories, pulmonary function.
