Factores sociodemográficos asociados a la actividad física deportiva en adolescentes mexicanos

Abstract

The objective of this study was to analyze changes in the prevalence of sports-related physical activity (SPA) in Mexican adolescents and its association with sociodemographic variables and the SPA of their parents. This is a cross-sectional and comparative study in which it was analyzed the National Survey of Use of Time (ENUT) versions 2002 and 2014, which is based on a representative sample of the entire Mexicans population over 12 years of age. The information of adolescents aged 12 to 19 years (n = 11,795) was selected, as well as that of their fathers (n = 8,161) or mothers (n = 10,261). Through a questionnaire, it was inquired about sociodemographic characteristics, SPA and the time allocated to perform it. Frequencies, Chi-squared, and Student T statistics and logistic regression models were estimated. In twelve years the prevalence of adolescent's reported SPA increased from 44.0% to 55.6% (p < 0.001), although there was no change in the reported time spent in this activity (p = 0.250). Adolescents who were girls, who were older, with parents and/or mothers with less schooling and those with parents who did not perform SPA were more likely that did not practice SPA. Reported SPA of adolescents was more related to fathers’ SPA than with the mothers’ SPA. Although the practice of SPA reported by Mexican adolescents increased in 12 years, there are groups with a low probability of performing it, in which policies and public programs designed to promote active lifestyles can be focused.
