Currently, childhood obesity is one of the most important public health problems, both in developed and developing countries. Objective To explore the association between body mass index (BMI) and waist circumference in students attending the Professional School of Physical Education at the National University of Callao. Materials and methods A quantitative, descriptive-correlational study was conducted with a convenience sample of 208 participants, including students and teachers. BMI and waist circumference were measured following standardized protocols, and advanced statistical models were used, including Pearson correlation analysis and nonlinear model fitting (polynomial, exponential, and logarithmic), as well as multivariate analysis to control for variables such as age, sex, physical activity, and eating habits. The results A moderate positive correlation (r=0.65; p<0.01) was obtained between BMI and waist circumference, although Cramér's V coefficient indicated a weak or null association between specific BMI categories and circumferences, suggesting complexity in the relationship. It was evident that some participants with a BMI in the overweight range had normal waist circumferences but had other indicators of metabolic risk, underscoring the need for nonlinear models to capture these complex relationships. It is concluded The relationship between BMI and waist circumference is significant but multifactorial, highlighting the importance of promoting healthy habits, thus contributing to health promotion strategies and prevention of diseases associated with overweight and obesity.
