Anthropometric indices such as Body Mass Index (BMI), waist circumference, and Waist-to-Hip Ratio (WHR) are commonly used to assess overall and central obesity. This study aimed to evaluate the relationship between Peak Expiratory Flow Rate (PEFR) and anthropometric parameters, including height, weight, BMI, waist circumference, and WHR among medical students.<br><strong>Material and methods: </strong>This cross-sectional study was conducted on 102 medical students. Anthropometric measurements, including height, weight, waist circumference, and hip circumference, were recorded, and BMI and WHR were calculated. PEFR was measured using Wright’s peak flow meter. Participants were informed about the study procedures, and demonstrations were provided before data collection. Statistical analysis was performed using SPSS software, and Pearson’s correlation coefficient was used to determine the association between PEFR and anthropometric variables.<br><strong>Results: </strong>PEFR showed a positive correlation with height, indicating better pulmonary function among taller individuals. In contrast, weight, BMI, waist circumference, and WHR demonstrated negative correlations with PEFR. However, the association between WHR and PEFR was not statistically significant.<br><strong><span lang="EN-GB">Conclusions: </span></strong><span lang="EN-GB">Anthropometric parameters significantly influence PEFR among medical students. Increased adiposity, particularly central obesity, may adversely affect respiratory function. These findings emphasize the importance of incorporating anthropometric assessments into respiratory health evaluations and promoting early lifestyle interventions to prevent obesity and preserve lung function in young adults.</span> http://www.ijsrdms.com/article_239065_4bbb39ab639f012b39af3565870ca322.pdf
