Aim Aging changes sleep patterns in most elderly people. Frailty shares a number of characteristics with sleep disorders and leads to similar results. However, their relationship in residents of long‐stay institutions remains unclear. Thus, the present study aimed to evaluate the relationship between sleep and frailty syndrome in residents of long‐stay institutions. Methods This was a cross‐sectional study of 69 institutionalized elderly in the city of J oão P essoa, B razil. The P ittsburg S leep Q uality I ndex, actimetry and specific tests for frailty phenotype variables were used. Pearson's χ 2 ‐test, one‐way anova and multiple linear regression were applied in statistical analysis. Results The sample was characterized as predominantly frail (49.3%), mainly women (62.3%), with a mean age of 77.52 years (±7.82). Frail elderly exhibited poor sleep quality, when compared with non‐frail individuals ( P = 0.02). In the multiple linear regression analysis, sleep latency ( R 2 = 0.11, P = 0.003) and sleep quality ( R 2 = 0.08, P = 0.013) had an influence on frailty, especially sleep quality. No differences were found between rest–activity pattern and frailty phenotype. Conclusion Sleep alterations, including poor sleep quality and prolonged latency, were related to frailty in institutionalized elderly. Geriatr Gerontol Int 2014; 14: 605–612.
