Secondary outcomes included exclusive supine position and room sharing without bed-sharing (collected at \u226560 days), prenatal planned exclusive supine position and room sharing without bed-sharing (reported at 36 weeks\u2019 gestation), and time-to-initial-report of nonexclusive supine, nonexclusive room sharing without bedsharing, and soft bedding use (collected through weekly text queries).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 1790 participants (86%) randomized, 1383 (77%) completed the 60+-day survey and were included in the analysis. Of these, 818 (59.1%) were aged 24 to 34 years; 323 (23.4%) were Black, 325 (23.5%) Hispanic, and 598 (43.2%) White. Participants were assigned to prenatal and postnatal intervention (n\u2009=\u2009337), prenatal intervention alone (n\u2009=\u2009344), postnatal intervention alone (n\u2009=\u2009334), or control (n\u2009=\u2009348); 12% of all participants received the intervention in Spanish. Among the primary outcomes, depending on the group, 87.6% to 92.2% of mothers reported usual supine position, 83.8% to 89.5% of mothers reported usual room sharing without bed-sharing, 75.6% to 84.5% reported no soft bedding use, and 72.5% to 76.0% reported pacifier use. There were no significant differences among groups for the primary outcomes. Among the 7 secondary outcomes, reported exclusive supine positioning at 60 days was higher among participants receiving the prenatal intervention than among controls (240\/343 [70.6%] vs 212\/348 [60.9%]; adjusted risk difference, 9.7% [95% CI, 3.8%-15.0%]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and
