Commuting reflects an important opportunity for youth to engage in physical activity. This study aimed to compare modes of commuting to school and to work and to identify sociodemographic factors associated with various modes of transportation.
Epidemiologic study with a repeated cross-sectional design. Participants included high school students (15–19 years of age) from Santa Catarina state, Brazil, in 2001 (n = 5028) and 2011 (n = 6529). A questionnaire containing information on the type of transport used to commute to school and to work was administered.
Walking/bicycling and the use of the bus to commute to school and to work remained stable after a decade; however, the use of car/motorcycle to school (6.4% versus 12.6%) and to work (10.2% versus 19.7%) increased significantly. In both cases, females more frequently used buses, whereas males commuted to work by car/bus. Students from rural areas more commonly commuted to school by car/motorcycle, whereas those from urban areas traveled to work more by bus. There was a greater use of cars/motorcycles by young people from higher-income families.
The use of cars/motorcycles to commute to school/work has almost doubled in the last decade. Sex, residential area and income were associated with passive commuting.

Our purpose was to examine the association of television viewing (hours/day), sedentary work (predominantly sitting at work), passive transportation to work (car or motorcycle), and the clustering of these behaviors (“sedentary lifestyle”), as well as leisure-time physical inactivity (LTPI), with chronic diseases (hypertension, hypercholesterolemia, type 2 diabetes, obesity, and clustering of chronic diseases) in Brazilian workers.
Cross-sectional study conducted from 2006 to 2008 in 24 Brazilian federal units (n = 47,477). A questionnaire was applied. Descriptive statistics, binary and multinomial logistic regressions were used.
Magnitude of association with chronic diseases varied greatly across domains and gender. Sedentariness at work was the most consistent behavior associated with chronic diseases, especially in men (ORhypertension = 1.10, 95% CI: 1.01–1.20; ORhypercholesterolemia = 1.34, 95% CI: 1.21–1.48; ORobesity = 1.27, 95% CI: 1.15–1.41; OR1chronic disease = 1.17, 95% CI: 1.09–1.26; OR≥2chronic diseases = 1.61, 95% CI: 1.46–1.78) compared with women (ORhypercholesterolemia = 1.15, 95% CI: 1.01–1.31; ORobesity = 1.24, 95% CI: 1.04–1.48). LTPI was associated with all diseases in men (except type 2 diabetes), but only with obesity in women.
Adverse health consequences may be differently associated according to behavior domain and gender. Sedentary work and LTPI were consistently associated with chronic disease in Brazilian workers, especially in men.
