Background:

Research has demonstrated that adolescents who actively commute have higher levels of physical activity (PA), which have declined precipitously over the past 30 years. The purpose of this study was to describe the prevalence of active commuting to school; and to identify barriers associated with active commuting.

Methods:

A cross-sectional study was conducted with 1672 students (46.8% boys and 53.2% girls) from 11 to 17 years of age in Caxias do Sul/RS, Brazil. The students were asked to answer questionnaires about active transport, PA, and sedentary behaviors. They also completed a cardiovascular fitness test and body composition measurements. The study used a multivariate Poisson regression analysis.

Results:

A total of 62.5% of students were observed to actively commute and the prevalence ratio (PR) of not actively commuting was associated with the type of school (Private: 2.41; 1.47, 3.95) and the time spent on commuting (>20 min: 1.93; 1.23, 3.03). The associated barriers to passive commuting were distance (3.02; 1.95, 4.71), crime/ danger (2.65; 1.82, 3.85), and traffic (1.75; 1.19, 2.58).

Conclusions:

This study showed that environmental variables were strongly associated with active commuting. However, no alterations in body composition or other behavioral variables were observed after adjustment.

Background:

Active commuting has decreased substantially in recent decades and has been more frequent in specific demographic and socioeconomic profiles. The objective of this study was to describe the prevalence of active trips and the possible associations with demographic and socioeconomic variables.

Methods:

A questionnaire on lifestyle and risk behavior was administered to a sample population of 5028 adolescents, ages 15 to 19 years, attending public high schools in the state of Santa Catarina, Brazil. Logistic regressions (odds ratio—OR; 95% confidence interval) were used to test associations.

Results:

Active commuting to school was reported for 56.7% of students, and active commuting to work was reported for 70.0%. The likelihood of commuting passively was greater among girls (school: OR = 1.27; 1.10−1.45), older adolescents (school: OR = 1.17; 1.02−1.33; work: OR = 1.49; 1.22−1.82), those who lived in rural areas (school: OR = 12.1; 9.91−14.8), those who spent more time in commuting (school: OR = 2.33; 2.01−2.69; work: OR = 4.35; 3.52−5.38), and those from high-income families (school: OR = 1.40; 1.21−1.62; work: OR = 1.69; 1.37−2.08).

Conclusions:

The proportion of students taking active trips was higher when going to work than to school. All indicators were associated with the mode of commuting, except gender and place of residence for commuting to work.
