Obesity and lack of exercise linked to chronic pain


It may not be surprising, but people who exercise at least one hour per week have a lower risk of troublesome back, neck, and shoulder pain, a new study shows.
The new evidence supports the possibility that obesity and physical inactivity play a role in a person's risk of developing chronic pain in those areas, said study co-author Dr. Paul Mork, of Norwegian University of Science and Technology in an email to Reuters Health.
Mork and colleagues followed more than 30,000 adults who participated in a large Norwegian health study. They recorded participants' body mass index (BMI) - a measure of weight related to height - at the start of the study, as well as how often they exercised, and then tracked them over the next 11 years.
The authors divided the participants into four categories based on how often they exercised, and four categories based on their BMI. They also looked at how many people in each category developed chronic neck, shoulder, and lower back pain.
Overall, 1 of every 10 people in the study developed lower back pain, and nearly 2 of every 10 developed shoulder or neck pain.
