However, existing evidence remains inconclusive because of variations in NVP definitions, limited sample sizes, and limited consideration of parity, despite potential differences in the caregiving burden between these two groups. We examined the association between postpartum depressive symptoms and the severity of NVP, assessed using multiple clinical criteria, stratified by parity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective cohort study was conducted of 2124 women who received perinatal care from early pregnancy to delivery at a tertiary hospital in Japan between 2018 and 2024. Postpartum depressive symptoms were defined as an Edinburgh Postnatal Depression Scale score \u2265\u20099 at 1\u2009month postpartum. NVP was clinically diagnosed and classified based on clinical interventions: no treatment, oral antiemetic use, intravenous therapy, and hospitalization.
