Quality of life and nutritional factors in elderly patients with non-dialysis chronic kidney disease
Quality of Life; Food Intake; Muscle Strength; Muscle Mass
Objective: To describe health-related quality of life and assess whether there is a correlation between this and nutritional factors (food intake, strength and muscle mass) in elderly people with non-dialysis chronic kidney disease. Method: This is a crosssectional study, the sample was non-probabilistic for convenience, composed of elderly patients treated at a referral outpatient clinic in Salvador-Bahia and who met the eligibility criteria. All patients were interviewed using a structured form for data collection. Health-related quality of life was assessed by the Medical Outcomes Study 36-Item Short Form Health Survey, food intake by 3-day food record, muscle strength by handgrip strength, and muscle mass by bioelectrical impedance. Data were analyzed using the Statistical Package for the Social Science version 21.0. To assess the correlation between continuous variables, Spearman's correlation coefficient was used. The value of p < 0.05 was considered to be statistically significant. Results: The dimensions that presented the lowest medians were limits by physical aspects followed by functional capacity. While the dimensions limited by emotional aspects and social aspects presented the highest medians. There were positive correlations between the time of diagnosis of chronic kidney disease and general health status (r = 0.323; p = 0.048), as well as between hand grip strength and functional capacity of the elderly (r = 0.342; p = 0.015). Conclusion: It is concluded that limits by physical aspects and functional capacity were the most compromised dimensions and the lower the functional capacity score, the lower the muscle strength of the evaluated elderly. The importance of evaluating the HRQoL is highlighted so that interventions are carried out early, in addition to the need for future studies to better understand the association between nutritional factors and quality of life.
