Hip and waist circumference correlations with demographic factors and pain intensity in patients with chronic pain

Aim: This study aimed to investigate how demographic factors such as race, age, sex and ethnicity can impact hip circumference (HC) and waist circumference (WC) in patients with chronic pain. Materials & methods: We queried the NIH-sponsored All of Us database for patients with documented HC, WC and waist/hip ratio (WHR) data. This cross-sectional study categorized participants into four groups: total cohort, no chronic pain, mild/moderate chronic pain (numeric rating scale < 7) and severe chronic pain (numeric rating scale > 7). Further subgroup analyses were performed based on race, age, sex and ethnicity. We examined the correlation between chronic pain and WC, HC and WHR. ANCOVA analysis was used to determine to investigate demographics. Results: This study included 204,013 participants, with 25.22% having a chronic pain diagnoses. In most subgroups, females had significantly greater HC, while males had greater WC and WHR. WC (p < 0.001 in females, p < 0.01 in males), HC (p < 0.001 in females) and WHR (p < 0.001 in females, p < 0.05 in males) were significantly greater in the severe pain group compared with the mild/moderate pain group. Conclusion: These findings suggest that when assessing HC and WC, demographic variables need to be considered to develop more personalized and comprehensive treatment plans for chronic pain patients.
