A cross-sectional study examined 62 patients with greater trochanteric pain syndrome. Pain intensity was significantly higher in the evening (average value 5) compared to morning and afternoon (average values 4). The average length of sleep was 6 hours, the average score of the Pittsburgh Sleep Quality Index (PSQI) reached the value of 9.0. The average proportion of body fat was 35.2%, the fat mass index 9.4 kg/m². There were statistically significant differences in PSQI global score, proportion of patients with poor sleep quality (PSQI > 5), body mass index, waist circumference, body circumference index, hip circumference and fat mass index between patients with low and high pain severity. Increased adiposity and impaired sleep quality are associated with greater trochanteric pain syndrome severity. The study confirmed the importance of the digital anthropometric approach in the assessment of body composition in these patients.
