Introduction:

Physical activity (AF in Spanish) is a factor that subdues health. In adults, the lack of AF is a determinant in cardiovascular risk; in children, the evidence of its effects is less, although there is a relationship between the development of obesity with factors of cardiovascular risk.

Objective:

To establish social determinants of health as predictors of a physical condition in school teenagers.

Method:

Descriptive and cross-sectional study with a sample of 339 previously selected students. We applied the Alpha Fitness guide to determine physical condition and a questionnaire about determinants.

Results:

84.4% of the school teenagers had an unhealthy physical condition. The determinants associated with the physical condition were the educational level of the father and smoking.

Conclusions:

An unhealthy physical condition was prevalent in the school teenagers. The educational level of the father and smoking were the predictive variables.
