Association between waist-to-height ratio and chronic pain among American adults: A cross-sectional study of the National Health and Nutrition Examination Survey.
Cross-sectional analysis reveals waist-to-height ratio affects chronic pain risk in adults, indicating obesity's role in health outcomes.
Key Points
This research aims to explore the connection between waist-to-height ratio and chronic pain among American adults.
Cross-sectional analysis using National Health and Nutrition Examination Survey data from 1999 to 2004.
Inclusion of 11,591 adults with chronic pain defined as self-reported pain lasting at least 3 months.
Utilization of multivariable logistic regression and restricted cubic spline models to assess relationships.
Subgroup analyses to examine confounding factors.
Higher waist-to-height ratio significantly associated with increased odds of chronic pain (OR = 3.16).
Participants in the highest quintile of waist-to-height ratio had increased likelihood of chronic pain compared to the lowest quintile (adjusted OR = 1.74).
Nonlinear association noted with an inflection point at an approximate waist-to-height ratio of 0.53.
