<b>Association Between Physical Activity Levels, Cardiovascular Health, and Waist-to-Height Ratio in Medical Students: A Cross-Sectional Study - </b>Dataset

Our research focused on assessing the relationship between physical activity and Cardiovascular Health Index among first-year medical students at a private university in Bogotá, Colombia. This study represents a secondary analysis of the ongoing longitudinal project 'Follow-up on the mind and body components in medical students at Universidad del Rosario,' which received ethical approval from the ethics committee of La Cardio (CEIC: 3907-2019, 0221-2023). All personal identifiers have been removed to preserve the anonymity of the participants.<br>A cross-sectional design was employed, with data collected from a non-probabilistic convenience sample of 113 first-semester medical students (ages 17-19) who were admitted to the School of Medicine and Health Sciences EMCS between April 2019 and February 2020. Students with chronic diseases such as hypertension, diabetes, or chronic kidney failure were excluded. Informed consent and assent were obtained from all participants prior to data collection, ensuring adherence to ethical standards.<br>Data were systematically captured using the Research Electronic Data Capture (REDCap) software. We presented categorical data as proportions and quantitative data using measures of central tendency (mean, median) and dispersion (standard deviation, interquartile range), depending on the data's normality and homoscedasticity. Statistical analyses included Student's t-test and Mann-Whitney U test for numerical variables based on their normality, and chi-square test for associations between qualitative variables. Spearman's correlation coefficient was used to explore the relationships between ISCV, METs of physical activity, and adiposity indicators (waist circumference and WHR). All analyses were performed with a 95% confidence level and a 5% significance level using R Studio 3.0.1.
