The association between obesity and chronic pain among community-dwelling older adults: a systematic review and meta-analysis.

OBJECTIVES

To systematically review studies and explore the association between obesity and chronic pain among community-dwelling older adults.

METHODS

A comprehensive literature search was conducted in 9 databases and the Pubmed search engine from their inception to March 19, 2020. Studies that investigated the associations between overweight/obesity and chronic pain among older people were obtained. Comprehensive Meta-analysis was used to meta-analyze the eligible studies.

RESULTS

Totally 14 studies with 40,999 participants were included in this review, and 8 of these studies were meta-analyzed. The meta-analyses showed that both overweight (pooled OR = 1.166, 95% CI: 1.104-1.232, p < 0.01) and obesity (pooled OR = 1.786, 95% CI: 1.530-2.085, p < 0.01) had significant associations with chronic pain among older adults.

CONCLUSIONS

Overweight and obesity are both associated with chronic pain among older adults. It is suggested that body weight control strategies might be incorporated into the pain management program for older adults with obesity.
