Sleep quality and frailty syndrome in community-dwelling older people: a cross-sectional study
Sleep quality, sleep disorders, frailty syndrome.
Introduction: Due to aging, physiological and psychological changes can impact sleep patterns, such as reduced sleep efficiency, fragmentation and a higher incidence of disorders such as insomnia and sleep apnea syndrome. Recent studies indicate that poor sleep quality is associated with frailty. As for Frailty Syndrome (FS), it is characterized by multisystemic decline resulting in an increase in adverse outcomes, such as falls, hospitalization, institutionalization and mortality. Objective: To investigate the relationship between sleep quality and frailty in the community-dwelling older people. Methods: This is a cross-sectional study that was carried out in Parnamirim/RN. The study population was made up of older people of both sexes aged 60 or over. Questionnaires were applied to evaluate variables such as: sociodemographic, anthropometric, chronic conditions, assessment of physical performance, assessment of frailty syndrome and sleep quality. For data analysis, the Statistical Package for Social Sciences (SPSS) version 20.0 software was used. To analyze the relationship between sleep variables and frailty, the chi-square test was used, while One-way ANOVA was used to compare the mean between the Pittsburgh Sleep Quality Index (PSQI)components and the Frailty Phenotype categories. Finally, a multiple linear regression was performed to verify the association between the variables studied. Results: In the descriptive analysis, the variables age and body mass index do not present a related association, as they do not present statistical significance where p=0.142 and p=0.003, respectively. Through multivariate multiple linear regression analysis of Pittsburg and frailty, it was shown that frail older people present changes in IPAQ (p<0.001; ß=1,07).
