Promoting active transportation is a challenge for the fields of public health and transportation. Descriptive data on the predictors of active transportation including seasonal patterns in active transportation in the US as a whole is needed to inform interventions and policies. Methods This study analyzed monthly variation in active transportation for the US using National Household Travel Survey 2001 data. For each age group of children adolescents adults and elderly logistic regression models were used to identify predictors of the odds of active transportation including gender race ethnicity household income level geographical region urbanization level and month. Results The probability of engaging in active transportation was generally higher for children and adolescents than for adults and the elderly. Active transportation was greater in the lower income groups except in the elderly was lower in the South than in other regions of the US and was greater in areas with higher urbanization. The percentage of people using active transportation exhibited clear seasonal patterns high during summer months and low during winter months. Children and adolescents were more sensitive to seasonality than other age groups. Women non-Caucasians persons with lower household income who resided in the Midwest or Northeast and who lived in more urbanized areas had greater seasonal variation. Conclusions These descriptive results suggest that interventions and policies that target the promotion of active .
