The goal of this observational study is to learn if surgical weight loss can improve chronic widespread pain in people living with higher BMI who self-identify as Hispanic/Latino ethnicity or non-Hispanic Black based on the United States census racial categories. The main questions the study aims to answer are: 1. Do pain at rest (primary outcome) and movement-evoked pain (secondary outcome) improve after bariatric surgery? 2. Do pain processing and joint function change after bariatric surgery? 3. Are pain processing and joint function associated with clinically significant pain change after surgical weight loss? Researchers will compare pain and function before and 6 months after bariatric surgery in a single cohort.
The central hypothesis that will be tested is that pain at rest (primary outcome) and movement-evoked pain (MEP, secondary outcome) will decrease after bariatric surgery. We will also determine if pain reduction will be mediated by improved pain modulation and select joint motion and loading variables. The study will feature a prospective, observational quasi-experimental cohort study design for within-group analyses of pain at rest and MEP using the Numeric Pain Rating Scale (NPRS) and other exploratory outcomes before and 6 months after bariatric surgery. Pain at rest and MEP at 3 months aft…
Inclusion Criteria: * Self-identify as Black/African American or Hispanic/Latino ethnicity based on the U.S Census racial categories * Eligible candidates for bariatric surgery (BMI greater than or equal to 40 or BMI greater than or equal to 35 with comorbidity * Meets criteria for chronic widespread pain (CWP) based on the following: 1. self-reported pain at 3 or more anatomical sites 2. painful regions on both sides of the body 3. self-reported pain intensity at rest of 3 out of 10 or higher using the Numeric Pain Rating Scale (NPRS) or equivalent * Conversational language fluency in…
Participants will include people with chronic widespread pain who will undergo bariatric surgery. All participants will receive this intervention and will not be randomized to this or other interventions.
