Back pain is among the most frequently reported health problems in the world. New research published in Arthritis Care & Research, an official journal of the American College of Rheumatology and the Association of Rheumatology Health Professionals, examines patterns in back pain over time and identifies the patient characteristics and the extent of healthcare and medication use (including opioids) associated with different patterns.
The study included a representative sample of the Canadian population that was followed from 1994 to 2011. A total of 12,782 participants were interviewed every two years and provided data on factors including comorbidities, pain, disability, opioid and other medication use, and healthcare visits.
During the 16 years of follow-up, almost half (45.6 percent) of participants reported back pain at least once. There were four trajectories of pain among these participants: persistent (18 percent), developing (28.1 percent), recovery (20.5 percent), and occasional (33.4 percent).
