Qualidade do sono em idosos na perspectiva da fragilidade clínico- funcional.

Abstract

To analyze the relationship between sleep quality and clinical-functional frailty in the elderly; estimate the prevalence of variations in sleep quality in the elderly; and verify the relationship between the sociodemographic profile and sleep quality in the elderly. Methodology: Cross-sectional observational and analytical epidemiological study, with a quantitative design, carried out in the municipality of Cuité, in the State of Paraíba. 82 intentionally selected elderly people living in urban areas participated. For data collection, the following were used: Sociodemographic questionnaire, Pittsburgh Sleep Quality Index (PSQI) and the Functional Clinical Vulnerability Index-20 (FCVI-20). To test the relationship between the variables, the Chi-square and Fischer's exact association tests were used, in addition to the Spearman correlation test. The prevalence ratio (PR) of the sleep quality index was also calculated, with the respective 95% confidence intervals (CI). Statistical significance was considered when p-value was less than 0.05. Results: A higher prevalence of poor sleep quality was found in elderly people aged 72 or over (PR = 1.36; CI 0.9-6.4); women (PR = 1.31; CI 0.8-5.2); elderly people with a partner (RP = 1.06; CI 0.3-2.0); in shared housing (PR = 1.24; CI 0.5-5.6); not functionally literate (PR = 1.06; CI 0.4-2.9); and active workers (RP = 1.09; CI 0.3-4.5), with no statistically significant association. An association and correlation was evidenced between the condition of clinical-functional fragility of the elderly and poor sleep quality. Conclusion: The more frail the elderly person, the worse their sleep quality, signaling the importance of incorporating the applicability of instruments to assess frailty and sleep quality in nursing practice, especially as they help in the early identification of changes and the promotion of measures that aim to maintain good sleep quality and robustness in this population.
