Peak expiratory flow (PEF) is a crucial parameter for assessing large airway function and lung ventilation capacity. PEF values are influenced by various factors, including physical activity levelsand nutritional status as measured through bodymass index (BMI). This study aims to investigatethe relationship between physical activity and BMI with PEF in the adult population within an academic work environment. An analytical observational study with a cross-sectional design was conducted at the Faculty of Computer Science, Kuningan University, from September to October 2025. A total of 57 respondents met the inclusion criteria. Physical activity was measured using the IPAQ-Short Form, BMI was measured using weight and height measurements, and PEF was measured using a Peak Flow Meter. Data analysis was performed using the Chi-Square test and analyzed using SPSS version 25. Most respondents had low physical activity (73.7%) and low PEF (59.6%). No significant relationship was found between physical activity and PEF (p = 0.611). In contrast, BMI showed a significant relationship with PEF (p = 0.026). There is a relationship between BMI and PEF, but no significant relationship was found between physical activity level and PEF in these research.
