Introduction:
Coxarthrosis has been considered a disease affecting the elderly; nonetheless, it is increasingly affecting younger people, resulting in their disability and absence from work.

Material and methods:
The study was conducted among 100 patients with coxarthrosis subsequently admitted to orthopaedic wards in regional hospitals. The results were obtained via an interview conducted with the patients as well as by means of an original survey questionnaire. The analysis was conducted for two groups, taking into account two age groups: the younger one (n = 30) – people below 60 years old and the older ones (n = 70) – people aged ≥ 60 years old.

Results:
The following factors predisposing to the development of coxarthrosis were the most observable in the younger group of patients: abdominal obesity – 27 (90%), faulty postures – 20 (67%), sedentary work ≥ 8 h/day in the absence of regular physical activity after work – 19 (63%), overweight – 15 (50%), hard physical work – 14 (47%), and standing work ≥ 8 h/day – 14 (47%). The following factors predisposing to the development of coxarthrosis were the most observable in the older group of patients: abdominal obesity – 67 (96%), sedentary work ≥ 8 h/day in the absence of regular physical activity after work – 43 (61%), faulty postures – 38 (54%), hard physical work – 37 (53%), overweight – 36 (51%), and metabolic syndrome – 33 (47%).

Conclusions:
The patients from the study group were burdened with numerous factors predisposing to the development of coxarthrosis, out of which the most frequent ones were: abdominal obesity and sedentary work, while a family history of degenerative changes occurred most rarely.
