Introduction: The disc disease of the lumbosacral spine is frequently occurs whose the main cause is the intervertebral disc degeneration. Pain in the lower back section of the spine and a considerable impairment of physical fitness is the main ailment. It is a chronic disease with periodic recurrent episodes of intense pain. Coping with the disease means, among other things, reinforcement perivertebral muscles through regular physical exercise. It is assumed that sociodemographic factors will be related to undertaking health-promoting actions in the form of physical activity adjusted to the degenerative disc disease of the lumbosacral spine. The aim of the paper was to answer the question whether demographic variables have any connection with undertaking physical activity adjusted to the disease of the lower back section of the spine. Material and methods: The study was a longitudinal type of research (two measurement points at half yearly interval) and it covered 92 people in whom the disc disease of the lumbosacral spine was found by means of MRI scan. The study used an interview (the sociodemographic data), the eleven-point VAS scale, and a questionnaire concerned undertaken phisical activity. Results: The patients showed a low level of physical activity undertaken due to the disease of the spine (M=2.33 SD=2.21). A dependency between younger age (H(2, N=92)=4.5, p<0.08) and higher education (H(3, N=91)=16.62,p=0.001) and undertaking physical activity adjusted to the disease of the lower back section of the spine was noticed. Conclusions: The people who took part in the study undertook little physical activity due to the spine disease. Age and education are related to the undertaking of physical activity adjusted to the disease of the lower back section of the spine.
