Resumen
Objetivo Identificar a través de un método de medición directo de la actividad física, las categorías en las que se ubican un grupo de estudiantes universitarios; así como relacionar estas categorías con variables de tipo sociodemográfico y antropométrico.
Métodos Estudio de corte transversal y fase comparativa en 601 estudiantes universitarios a los que se les indagó sobre las variables sociodemográficas: género, edad, estado civil y estrato socioeconómico y autopercepción de salud. Se determinó el Índice de Masa Corporal y los niveles de actividad física mediante el Test de Clasificación de Sedentarismo de Pérez-Rojas-García sobre el comportamiento de la frecuencia cardíaca.
Resultados Se observó diferencias significativas (p=0,000) en la frecuencia cardíaca entre activos e inactivos, en los inactivos fue de 143,4 p/m en comparación con 115,1 p/m en los activos. Con respecto a los resultados de la regresión logística, los estudiantes de género femenino presentan mayor riesgo de ser inactivos físicamente con la prueba objetiva [OR 2,6 (1,9-3,6)]; asimismo, se observa que las personas con sobrepeso y obesidad tienen mayor probabilidad de ser inactivos [OR 1,9 (1,4-2,9)].
Conclusión Se evidencia una elevada frecuencia de inactividad física en la población universitaria, asociada significativamente a la obesidad y al género femenino, datos que se convierten en una línea de base fundamental para la elaboración de programas de entrenamiento y actividad física específicos para población universitaria.
Objectives To identify the categories in which a group of university students are classified by directly measuring physical activity, and to relate these categories with socio-demographic and anthropometric variables. Materials and Methods Cross-sectional and comparative phase study in 601 university students who were interviewed to inquire about socio-demographic variables such as sex, age, marital status, socioeconomic status and self- perceived health. Body Mass Index (BMI) and physical activity levels were determined by applying the Perez-Rojas-García Sedentarism Classification Test on heart rate behavior. Results Significant heart rate differences (p=0.000) between the active and the inactive group of university students were observed. The inactive group had a heart rate of 143.4 bpm compared to 115.1 bpm in the active group. Regarding the results of the logistic regression, female students had a greater risk of being physically inactive in the objective test [OR 2.6 (1.9 to 3.6)], while overweight and obese people are more likely to be inactive [OR 1.9 (1.4-2.9)]. Conclusion The assessment shows that a high prevalence of physical inactivity in university students is significantly associated with obesity and the female sex. This information is fundamental for designing specific training programs and physical activities for university students.
