The understood effect of body mass index (BMI), advanced maternal age (AMA), and second stage of labor on obstetric anal sphincter injury (OASIS) at delivery is varied. The objective of this study was to assess whether incorporating BMI, second stage of labor length, and AMA into a model for predicting OASIS among forceps\u2010assisted vaginal deliveries (FAVD) had a higher predictivity value compared to models without these additions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>This was an IRB\u2010approved retrospective cohort study of singleton gestations who underwent a FAVD between 2017 and 2021.

Comparisons of known factors that predict OASIS (nulliparity, race, episiotomy status) to known factors with additional predictors (BMI, AMA, and length of second stage in labor) were explored. After comparing each model's AUC to one another (a total of 3 comparisons made), there was no statistically significant difference between the models (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&gt;\u20090.62).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Including BMI, AMA, and second stage of labor length does not improve the predictivity of OASIS in patients with successful FAVD.
