« The purposes of this study were to establish the proportion of children who walked, used public transit, were driven in a school bus or vehicle, or used multiple transportation modes to school and to identify socioeconomic correlates. » (p. 65)
« Data for this study were from the 1999 Quebec Child and Adolescent Health and Social Survey (QCAHS), which is a representative population-based community survey that sampled 3613 youths in the province of Quebec, Canada aged 9, 13, and 16 years old (Paradis et al., 2003). » (p. 64)
Type de traitement des données :
« We [...] describe the proportion of children who walked, used public transit, were driven in a school bus or vehicle, or used multiple transportation modes to and from school. Estimates are stratified by age, sex, 1998 household income, urban versus rural settings, and parents’ birthplace. [...] This study’s main strength is that it is a representative population sample, generalizable to Quebec, yielding valid proportion estimates of students using various modes of transportation to school. However, the current study does not account for the travel distance between home and school nor for weather variations across seasons, which are substantial in Quebec. Also, the response options did not include alternative modes of transportation such as cycling, skateboarding, or rollerblading. The study findings indicate that more systematic observation of modes of transportation to school has relevance for local population surveillance and cross-settings comparisons. Researchers and public health practitioners can determine if target populations are using active modes of transportation to school and establish public health goals for active commuting among youth. » (pp. 64-65)
