Pre-operative cardiopulmonary, metabolic, abdominal, and somatic variations by race in men with obesity resolve after Laparoscopic Roux-en-Y gastric bypass (LRYGB): Dyslipidemia and psychologicals by race persist

Published:October 15, 2022DOI:


      • The preoperative disease is seen more in Laparoscopic Roux-en Y white males.
      • Most comorbidities persist at 12 months, in patterns similar to preoperative period.
      • Only 3 comorbidities vary at 24 months.



      Whether/how LRYGB men vary by race in clinical characteristics/post-operative outcomes is unknown.


      Identify male pre-/post LRYGB clinical/outcomes variations by race.


      Data from 17,734 LYRGB BOLD database men were analyzed in five groups: African American (AA, n = 1310), Caucasian (C, n = 14,168), Asian (A, n = 53), Hispanic (H, n = 1519), and Other (O, Pacific Islander, Native American, or more than one race, n = 684). Data: demographics, BMI, and 28 weight-related conditions.


      Pre-LRYGB age, health insurance, unemployment, BMI, and 24/28 obesity related comorbidities varied by race (p < 0.01). Highest pre-LRYGB: AA 4, C 14, A 5, H none, O 1 comorbidity. 12 month BMI and 14 comorbidities varied by race (p < 0.05). 24 months only dyslipidemia, depression, and psychological impairment varied by race (p < 0.05).


      Demographics, BMI and 24 obesity comorbidities vary by race in LRYGB men, but only 3 at 24 months. Caucasians have the greatest cardiopulmonary related comorbidities. This advanced knowledge may facilitate peri-operative management.
