While various studies have explored the effects of BMI on clinical outcome measures, current literature examining the effects of BMI on patient-reported outcome measures is lacking. This study aimed to analyze the effects of patient BMI on pre- and postoperative 10-item Patient-Reported Outcomes Measurement Information System (PROMIS-10) global health T-scores for patients undergoing transforaminal lumbar interbody fusion (TLIF).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>\n                      A prospectively collected multi-institutional quality registry was retrospectively reviewed.

At baseline, nonobese patients had significantly better mean PROMIS-10 GPH T-scores (36.7 \u00b1 6.6) than class II or III obese (33.9 \u00b1 6.2) (p = 0.003) patients. By 3 months, mean GPH T-scores improved significantly in all groups (p &lt; 0.001), with the nonobese group (12.3 \u00b1 8.1) demonstrating similar improvement to class I obese (12.0 \u00b1 8.3, p = 0.7) and class II or III obese (11.0 \u00b1 8.1, p = 0.3) patients. Likewise, mean GMH T-scores improved significantly in all groups by 3 months (p &lt; 0.001), with the nonobese group (7.1 \u00b1 8.7) demonstrating similar T-score improvement to class I (6.5 \u00b1 8.1, p = 0.8) and class II or III (4.3 \u00b1 8.0, p = 0.070) obese patients.
