- Poor posture and spending long periods in one position e.g. working at a computer, slouching in front of TV.
- Obesity. The increased weight causes wear and tear of the disks and facet joints.
- Genetic factors. Some people are genetically susceptibility to back pain, usually from inheriting spinal structural abnormalities. Mutation of the COL9A2 gene may be linked to about 10% of sciatica cases. This gene plays a role in producing collagen, an important protein component of the discs. The defective gene may cause disc deterioration, leading to sciatica.
- Work that stresses the back: risky activities include lifting, forceful movements, bending and twisting into awkward positions, repetitive movements and vibration (as occurs with long-distance truck driving).
- Improper body mechanics during sporting activities can damage the back e.g. a jerky golf swing or incorrect use of exercise equipment. Cyclists often experience low back pain, which is often resolved by adjusting the angle of the bicycle seat. Some research suggests that, over time, high-impact exercise such as rugby or aerobics may increase the risk for degenerative disc disease.
- Pregnancy makes women prone to back pain due to shifting of abdominal organs, forward redistribution of body weight, and loosening of ligaments in the pelvic area prior to delivery.
- Smoking, possibly because it decreases blood circulation to the tissues of the back. The association may also be due to a generally unhealthy lifestyle.
- Psychological factors. Research indicates that in many people, pre-existing depression and feelings of helplessness may contribute negatively to the perception of pain and the ability to cope with back problems. People in depression are also more likely to have vague physical symptoms, including back pain.
