Current international epidemiologic studies of low back pain indicate that almost everyone suffers from low back pain sooner or later in their lives. Surveys show that 79% to 80% of the entire population has experienced low back pain, and up to 50% of adults in the working age range experience some degree of low back pain each year, with 15% to 20% of them seeking medical attention. Low back pain ranks among the top 10 reasons for medical visits, is the third most prevalent chronic disease after respiratory disease and coronary heart disease, and is the most common cause of disability in people under 45 years of age. Based on the impact of low back pain on human health, society and economy, the medical profession has listed low back pain as one of the key research topics. Outpatients often ask me, “Doctor, what’s wrong with my low back pain? What causes it?” Many patients tell me, “I don’t do anything every day, why do I have low back pain?” Through repeated questioning of their medical history, I found that most of the patients with low back pain have one thing in common, that is, they all have occupational causes or bad lifestyle habits that lead to strain on the muscles of the lower back. The mechanism that produces low back pain is due to prolonged poor posture of the lower back, lumbar muscle fatigue, lumbar spine small joints and intervertebral discs with increased load and degeneration, which ultimately leads to pain. What are the risk factors for low back pain? 1, common occupations: teachers, drivers, service personnel, office clerks and other work in the sedentary or standing crowd, heavy labor is also a risk of back pain occupation. 2, common bad habits: long time use of computers, semi-recumbent reading, watching TV, playing cell phones, etc. The spine in the sitting position by the load is higher than the standing position, increase the back can cause a sharp increase in lumbar intervertebral disc pressure. Epidemiology and post-mortem examination have found that the load in industrial work can cause damage to the spinal structure, and the tiny fracture and scar formation caused by it may be an important factor in accelerating the metamorphosis of the intervertebral disc. 3, Psychosocial factors. Depression, poor job satisfaction, emotional pain and so on. 4.Past history of low back pain. Risk factors that have a moderate correlation with the development of low back pain include: (1) strenuous exercise; (2) smoking; (3) excessive height; (4) poor body uniformity; (5) little exercise and activity; and (6) obesity.
