However, extant research is mixed regarding the direction of these changes, with some studies identifying relief from ED symptoms and others finding evidence of worsening symptoms during this time. To account for heterogeneity in ED symptom change among pregnant and postpartum individuals, the current study aimed to explore ED symptom trajectories and their psychosocial correlates during pregnancy and the first postpartum year using person\u2010centered statistical approaches.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      A community sample of pregnant people recruited online (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009315) completed assessments of ED symptoms and psychosocial factors during pregnancy, 8\u2010weeks postpartum, and 1\u2010year postpartum between October 2020 and January 2023. ED symptom trajectories were identified using group\u2010based multivariate trajectory modeling. Multinomial logistic regression tested if psychosocial factors (anxiety, depression, stress, emotion regulation difficulties, self\u2010compassion, social support, and body mass index) during pregnancy and across postpartum were associated with trajectory groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Four distinct groups were identified: decreasing ED cognitions group (34% of the sample), increasing ED symptoms group (29%), early postpartum ED risk group (22%), and early postpartum alleviation group (15%).
