[Association between weight-adjusted waist index and pain: A cross-sectional study]

Area of Science:

• Medical Science
• Epidemiology
• Public Health

Context:

• The weight-adjusted waist index (WWI) is a measure of central adiposity.
• Chronic pain affects a significant portion of the adult population, impacting quality of life and healthcare costs.
• Understanding the relationship between body composition and pain is crucial for developing effective prevention and management strategies.

Purpose:

• To investigate the association between the weight-adjusted waist index (WWI) and the prevalence of acute, subacute, and chronic pain among American adults.
• To determine if WWI is an independent risk factor for different pain statuses, controlling for various demographic and lifestyle factors.

Summary:

• A cross-sectional study of 12,694 American adults using NHANES data (1999-2004) analyzed the relationship between WWI and pain. Results indicated no significant association between WWI and acute or subacute pain.
• Higher WWI quartiles were significantly associated with an increased prevalence of chronic pain, even after adjusting for covariates. This association remained significant across multiple regression models.

Impact:

• This study highlights a potential link between central obesity, as indicated by WWI, and the development or exacerbation of chronic pain.
• Findings suggest that WWI could serve as a useful indicator for identifying individuals at higher risk of chronic pain.
• Further large-scale prospective studies are recommended to validate these findings and explore potential underlying mechanisms.
