Introduction and objective:
According to recent epidemiological data, approximately 70% of the population experience lumbosacral pain, and 50% cervical spine pain before reaching the age of 40. These conditions represent a serious medical, social and economic problem. Many environmental factors exert an effect on the development of spinal disorders: lack of physical activity, poor work ergonomics, spinal overload, advanced age, overweight and behavioural factors. Objective: The aim of the study was to assess the severity of disability caused by spinal pain, with consideration of the impact of environmental factors.

Material and methods:
The study group consisted of 142 people suffering from spinal disorders. Their level of disability was assessed using an anonymous questionnaire based on the Neck Disability Index (NDI) and the Oswestry Disability Index (ODI). Additionally, demographic data were collected, such as age, gender, body mass index (BMI), type of occupation performed, place of residence, and the level of physical activity.

Results:
The study demonstrated that age, the lack or insufficient physical activity (once-twice per week), and place of residence are factors significantly affecting the severity of disability. However, no such relationship was found between body mass index (BMI), type of occupation, or gender. The evaluation of the relationship between different types of spinal disorders and the severity of disability revealed that the type of disorders significantly affects the level of disability

Conclusions:
There is a need to clarify and expand healthcare programmes, particularly in the areas where medical services are observed to be deficient. Educational support for the population is recommended, which may contribute to the reduction of the prevalence of spinal pain resulting especially from lack of adequate physical activity.
