NEW YORK (Reuters Health) - there may be no surprise, but people who exercise have at least one hour per week a lower risk of troublesome back, neck, and shoulder, a new study shows pain.
The new evidence supported the possibility that obesity and physical inactivity, risk play a role in a person the development of chronic pain in these areas, said study co-author Dr. Paul Mork of the Norwegian University of science and technology in an email to Reuters Health.
Mork and colleagues followed more than 30,000 adults, in a large Norwegian study of health participated. Participants took body mass index (BMI) - a measure of weight related to height - at the beginning of the study and how often they exercised, and she followed in 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. She saw how many people in each category developed chronic neck, shoulder and lower back also.
Total 1 developed 10 people in the study in the lower back and almost 2 of each 10 developed shoulder or neck pain.
After taking into account account participants age, BMI, whether they smoked, and whether they were doing manual work in the workplace,
The research team found that men exercise were 2 hours or more per week at the beginning of the study were 25 percent less likely to pain eleven years later, and 20 percent less as have have lower back neck or shoulder pain, compared to men who do not exercise at all. And women who exercised at least 2 hours per week, that 8 per cent less likely lower back to develop less likely than women to develop neck and shoulders pain pain that were inactive, and 9 percent.
Weight, influenced, not surprisingly, also the risk of chronic pain later. Obese men were almost 21 percent of normal weight and 22 percent more likely to develop more for chronic back pain than men to develop shoulder neck or pain. Obese women was also 21 percent to develop pain in the lower back neck and shoulders rather than more likely to develop women normal weight and 19 per cent.
Based on the results, Mork, believes that even moderate physical activity - only an hour or more per week - "can, compensate for overweight and obese at future risk of chronic pain to some extent for the adverse effect of being."
Reuters Health via e-Mail "chronic neck and back pain disability and health care are important for public health due to their influence on the quality of life, resources," said Dr. Adam Goode at Duke University in Durham, North Carolina. Goode, a physiotherapist, was not in the study of Mork of the group.
Back in the mid-1990s years a study from the Netherlands estimated that low back pain almost cost the country 2 percent of its gross national product. In their new paper Mork and colleagues write that "only a small reduction in the incidence of chronic back pain would have a profound economic impact."
Due to the way that it's designed, not the Norwegian study can prove that sedentary and overweight people actually causes chronic pain or prevent it regular exercise and a more healthy weight. It could be that the people who have or do not have different chronic pain in ways that do not measure the study.
But given the known benefits of exercise and maintaining a healthy weight, believes Mork, the "community-based measures to reduce the incidence of chronic pain... should promote aim at regular physical activity and maintaining normal body weight."
