Relation between body mass index, waist circumference, and a body shape index with VO2 max among medical students in Jakarta, Indonesia

Background: Individuals with low VO2 max have higher potential of chronic disease in later life. Body fat composition is a factor that affects VO2 max. A sedentary lifestyle and poor diet in medical students can lead to excess body fat mass, which can be measured through BMI, WC, and ABSI. Objective: The study aimed to determine the relation between BMI, WC, ABSI, and VO2 max in medical students. Methods: This study used an observational analytic method and a cross-sectional approach. It was conducted at the Medical Education and Research Center UPNVJ from January to December 2024. The sampling technique was simple random sampling with total sample size of 46 respondents. Data collection involved filling out a questionnaire and measuring BMI, WC, ABSI, and VO2 max. Statistical analysis in this study was performed using the Mann-Whitney test. Results: Most respondents had normal BMI, normal WC, and low ABSI. The results of bivariate analysis showed relation between WC and VO2 max (p = 0.000), and there was no relation between VO2 max with BMI (p = 0.344) and ABSI (p = 0.956). Conclusion: The study's results conclude that WC and VO2 max are related. However, there was no relation between BMI and ABSI and VO2 max in medical students.
