[Sleep disturbances are associated with frailty in older adults].

Background: Sleep plays a vital role in good health. Since sleep disturbances have been linked to a series of adverse physical health outcomes, the objective was to analyze the association between sleep disturbances and the frailty criteria in Mexican older adults from Mexico City.

Methods: The study design was cross-sectional. A total of 1252 people aged 60 years or older were assessed according to Fried criteria for defining frailty. Sleep disturbances (sleeping without rest, sleeping more than usual and having trouble sleeping) were collected by self-report through a face to face questionnaire. The association between sleep disturbances and frailty was estimated with ordinal logistic regression controlled by covariates.

Results: It was found that 6.9% of older people reported sleeping more than usual, 18.9% slept without rest and 16.3% had trouble sleeping. There was a statistically significant association between sleeping more than usual (OR = 1.96, 95% CI: 1.23-3.12) and having trouble sleeping (OR = 1.53, 95%CI: 1.09-2.17) with frailty.

Conclusion: Sleeping more than usual or having trouble sleeping contribute to increase frailty in older people from Mexico City.
