Insomnia, low sleep quality, and sleeping little are associated with frailty in Mexican women

Abstract Objective To analyze the influence that sex has on the association between insomnia, sleep quality, sleep duration, and frailty in older adults Subjects & Methods Cross sectional study from the Cohort Obesity, Sarcopenia, and Frailty in Older Mexican Adults (COSFOMA). In total, 493 older adults aged 64–94 participated. Insomnia was evaluated with the Athens Insomnia Scale and sleep quality with the Pittsburgh Sleep Quality Index. Duration of sleep was classified as short ( Results Participants included 299 (60.7 %) women and 194 (39.3 %) men. The average age was 70.1 ± 5.6 years. Frail older adults comprised 13.4 % of the sample (n = 66), while 62.5 %(n = 308) were pre-frail and 24.1 % were not frail (n = 119). In the statistical models adjusted for sociodemographic and health covariates, insomnia, low sleep quality, and sleeping less than five hours were shown to increase the odds of being frail in women, but not in men. Conclusion In older adult women, the presence of insomnia, low sleep quality, and sleeping less than five hours could promote frailty. Therefore, treatment of sleep problems among women should be prioritized to avoid the onset of this condition.
