Body Mass Index and Postsurgical Outcomes in Older Adults.

ABSTRACT:

Importance

High body mass index (BMI) has been associated with increased postoperative complications including mortality in the general population, leading many perioperative clinicians to recommend preoperative lifestyle modifications aimed at achieving normal body weight. However, aging introduces physiological changes associated with frailty, such as altered body composition, fat redistribution, and stature reduction due to height loss, all of which may modify the association between BMI and surgical outcomes in older adults.

Cohort study of adults aged 65 years or older presenting for su
