Pain is a significant burden within the U.S. adult population, but little is known regarding epidemiology of pain, particularly with respect to race, ethnicity, and socioeconomic position (SEP). ⋯ Trends of chronic pain by SEP were opposite of acute pain as those in the highest SEP group tended to have less chronic pain than those in lower SEP groups. These findings suggest that SEP, in addition to race and ethnicity, may play a role in the development of pain as well as its treatment and management.

The objective of this study is to assess the autonomic nerve heart rate regulation system at rest and its immediate response to paced breathing among patients with complex regional pain syndrome (CRPS) as compared with age-matched healthy controls. ⋯ The increased heart rate and decreased HRV at rest in patients with CRPS suggest a general autonomic imbalance. The inability of the patients to increase HRV time domain values during paced breathing may suggest that these patients have sustained stress response with minimal changeability in response to slow-paced breathing stimuli.
