However, it is unclear if diagnosing GDM thus motivates women to increase physical activity after pregnancy or if this medicalization has the opposite effect of decreasing activity, possibly reflecting assumption of a sick role. We thus sought to evaluate the impact of diagnosing GDM on changes in maternal physical activity after pregnancy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this prospective cohort study, physical activity patterns were assessed by the Baecke questionnaire for the year before pregnancy and the first year postpartum in 405 white women comprising the following three gestational glucose tolerance groups: (a) those who did not have GDM (non\u2010GDM; n\u2009=\u2009247), (b) women with undiagnosed GDM (n\u2009=\u200946) and (c) those diagnosed with GDM (n\u2009=\u2009112).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the year before pregnancy, mean adjusted total physical activity progressively decreased from non\u2010GDM to undiagnosed GDM to diagnosed GDM (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.067).
