Objective

The purpose of the study is to identify factors that may influence the functional limitations of hemodialysis patients and analyze their level of physical activity.

Material/patients and methods

Cross-sectional descriptive study, for adult patients on chronic hemodialysis in the Hôtel-Dieu de France Hospital. A 32-item questionnaire explores the personal data, etiology of renal failure, associated defects, technical data of hemodialysis and seniority, the current seat and pain. Physical activity was assessed by the modified BAECKE score. The information processing is performed with SPSS (Spearman tests, ANOVA and logistic regression). The significance level is 0.05 with information processing is performed with SPSS (Spearman tests, ANOVA and logistic regression). The significance level is 0.05 with descriptive, univariate and multivariate analysis.

Results

Descriptive analysis. Fifty patients. Mean age 58 years, 56% are female. BMI: 5.71 kg/m ² . Work 70% before dialysis and 40% after. Etiology of failure: diabetes 28%, hypertension 24% and 20% hereditary connectivitis 12%, chronic urinary tract infections 8% and 2% idiopathic. Joint pain 36%, cardiac failure 26%. Dialysis: three times per week 66%. Average length of dialysis 82 months. Sports: 52% of moderate intensity on the score do BAECKE total (ST) between 1 and 14.78 average 5.36. Univariate analysis. Items related to a total score of BAECKE low: older age ( P = 0.002), lack of employment ( P = 0), chronic urinary tract infections ( P = 0.009), osteoarthritis ( P = 0.003) or pain joints ( P = 0), a high frequency of dialysis per week ( P = 0), the presence of current pain ( P = 0.024). Multivariate analysis. Aggravating factors: chronic infections of the urinary tract ( P = 0.012), the presence of articular pain ( P = 0.024), and a high frequency of dialysis per week ( P = 0.004).

Discussion–conclusion

The study focuses on factors influencing the decline in physical activity among hemodialysis patients and shows that most patients do not work and have no physical activity and sport. It would be imperative to enable multidisciplinary management and emphasize the role of rehabilitation and exercise in improving the handicap.
