933 - Hip and waist circumference correlations with demographics and pain intensity in patients with chronic pain

Objectives: Hip and waist circumference have been proposed to better correlate with chronic pain conditions than body mass index (BMI). To ensure a representative sample from across U.S including races, ethnicities, and socioeconomic backgrounds, data were obtained from the NIH-sponsored All of Us database to determine the relationship of waist and hip circumference and chronic pain across groups.

Design: We investigated waist circumference (WC), hip circumferences (HC) and the waist/hip ratio (WHR) across different cohorts categorized by sex, race, ethnicity and presence of chronic pain. All participants were further divided into four cohorts (total, without chronic pain, those with mild/moderate chronic pain (numeric rating scale (NRS) < 7), and those with severe chronic pain NRS > 7.

Results: A total of 204,013 participants aged between 18 and 100 years were included. 25.22% of the total cohort had chronic pain diagnoses with 80% described as either chronic pain not otherwise specified or fibromyalgia. In all cohorts, females had significantly greater HC while males had greater WC and WHR. Race and ethnicity also had a significant effect on HC and WHR. WC, HC, and WHR were significantly greater in the severe pain group as compared to the mild moderate pain group (< 0.001).

Conclusions: When offering treatment to patients with chronic pain, it is important to holistically manage patients. These data suggest that when assessing hip and waist circumference demographic variables need to be considered. The relationship between hip and waist circumference in patients with severe pain should be followed to determine the correlation as pain is relieved.
