title: Changes in mode of transportation to work or school from pre-pregnancy to early pregnancy in the Norwegian Fit for Delivery study.
abstract: OBJECTIVE
  To describe changes in mode of transportation to work or school from pre-pregnancy to early pregnancy, to describe levels of physical activity related to mode of transportation to work or school, and to examine associations between changes in mode of transportation to work or school and educational level, body mass index (BMI) and age.
  
  
  METHODS
  Between September 2009 and February 2013, 575 healthy pregnant nulliparous women were included into the Norwegian Fit for Delivery (NFFD) trial. At inclusion they reported their current and their pre-pregnancy mode of transportation to work or school. Data were analysed by multilevel mixed models with dichotomized modes of transportation as dependent variables.
  
  
  RESULTS
  There was a significant change towards less active transportation to work or school and a decrease in level of physical activity from pre-pregnancy to early pregnancy. Pre-pregnancy, 58% used private transportation to work or school, compared to 64% in early pregnancy (p = 0.001). The percentage of women who biked (11% v. 5%, p < 0.001) decreased significantly from pre-pregnancy to early pregnancy.
  
  
  CONCLUSIONS
  In this sample of Norwegian women there was a significant change towards less active transportation to work or school and lower levels of physical activity from pre-pregnancy to early pregnancy.
