Socio-economic factors and active commuting to school in urban Spanish adolescents: The AVENA study

Abstract

Background: This study aimed: (i) to describe the patterns of commuting to school in urban Spanish adolescents; and (ii) to examine the associations between active commuting to school (ACS) and socio-economic factors.Methods: From the AVENA Study, 2183 adolescents (1142 females) aged 13-18.5 years were gathered. Mode and time of transportation to school were self-reported by the adolescents. Parental education level (primary, secondary or university degree), parental professional level (managerial, skilled worker or unskilled worker/unemployed) and the type of school (public or private) were self-reported by the parents. The relationships between ACS and socio-economic factors were analysed by binary logistic regression.Results: Nearly <65 of the adolescents reported ACS and 83 of them spent <15 min travelling to school. In male adolescents, maternal primary education level showed an odds ratio (OR) of 1.55 (95 confidence interval, 1.12-2.15), with respect to mothers with a university degree. In female adolescents, mothers with a primary education level showed an OR of 0.68 (0.50-0.92), with respect to mothers with a university degree. Low maternal professional level showed an OR of 1.70 (1.29-2.24), with respect to high maternal professional levels. Students attending public schools showed an OR of 3.47 (2.46-4.90), with respect to students from private schools.Conclusion: Most of the adolescents actively commuted to school, yet the time spent commuting was low. Socio-economic level seems to be inversely related to the ACS in adolescents. Type of school and maternal educational level were the main predictors of ACS.
