Bivariate analyses examined the relationships between breastfeeding exclusivity and various factors, including maternal demographics, birth characteristics, and case\u2010control status. Breastfeeding exclusivity, cessation, challenges, and formula introduction were determined from self\u2010reported infant feeding surveys administered to participants at 6 to 10 weeks, 4 months, and 6 months postpartum. Regression models were used to describe the relationship between breastfeeding exclusivity, breastfeeding duration, and PPH, adjusting for relevant confounding variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      EBF rates for participants with normal postpartum bleeding versus PPH were 82.5% versus 64.1% (\n                      <jats:italic>P<\/jats:italic>\n                      =\u00a0.05), 77.5% versus 55% (\n                      <jats:italic>P<\/jats:italic>\n                      =\u00a0.02), and 70.3% versus 49.1% (\n                      <jats:italic>P<\/jats:italic>\n                      =\u00a0.04) at 6 to 10 weeks, 4 months, and 6 months, respectively. Early EBF (6\u201010 weeks) was more strongly associated with psychosocial factors, including higher education, lower depression scores, and higher resilience scores. Median ferritin levels at 6 to 10 weeks postpartum were higher in those who continued to exclusively breastfeed at 4 and 6 months (24.1 ng\/mL; interquartile range [IQR], 14.7\u201046.5) compared with those who did not (17.7 ng\/mL; IQR, 10.3\u201032.0) (\n                      <jats:italic>P<\/jats:italic>\n                      =\u00a0.03 for both).
