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 (<5 h and 5-6 hours), recommended (7-8 hours), and long (≥ 9 h). Frailty was operationalized with the Fried phenotype. Furthermore, sociodemographic variables were collected, along with physical and mental health. Logistic regression models were stratified by sex to analyze the relationship between insomnia, sleep quality, sleep duration, and frailty. 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.

失眠、睡眠质量低和睡眠不足与墨西哥女性虚弱有关

目的分析性别对老年人失眠、睡眠质量、睡眠时间和虚弱之间关系的影响。主题和方法 来自墨西哥老年人群肥胖、肌肉减少和虚弱 (COSFOMA) 的横断面研究。共有 493 名 64-94 岁的老年人参加。失眠使用雅典失眠量表进行评估，睡眠质量使用匹兹堡睡眠质量指数进行评估。睡眠时间分为短（<5 小时和 5-6 小时）、推荐（7-8 小时）和长（≥ 9 小时）。使用 Fried 表型可操作性虚弱。此外，还收集了社会人口变量以及身心健康。Logistic回归模型按性别分层，分析失眠、睡眠质量、睡眠时间和虚弱之间的关系。结果 参与者包括 299 (60.7 %) 名女性和 194 (39.3 %) 名男性。平均年龄为 70.1 ± 5.6 岁。体弱的老年人占样本的 13.4% (n = 66)，而 62.5 % (n = 308) 为体弱前体，24.1 % 未体弱 (n = 119)。在根据社会人口统计学和健康协变量调整的统计模型中，失眠、睡眠质量低和睡眠不足 5 小时会增加女性虚弱的几率，但不会增加男性。结论 在老年女性中，失眠、睡眠质量低和睡眠不足 5 小时会导致虚弱。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。5 % (n = 308) 体弱前，24.1 % 未体弱 (n = 119)。在根据社会人口统计学和健康协变量调整的统计模型中，失眠、睡眠质量低和睡眠不足 5 小时会增加女性虚弱的几率，但不会增加男性。结论 在老年女性中，失眠、睡眠质量低和睡眠时间少于 5 小时会导致虚弱。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。5 % (n = 308) 体弱前，24.1 % 未体弱 (n = 119)。在根据社会人口统计学和健康协变量调整的统计模型中，失眠、睡眠质量低和睡眠不足 5 小时会增加女性虚弱的几率，但不会增加男性。结论 在老年女性中，失眠、睡眠质量低和睡眠不足 5 小时会导致虚弱。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。失眠、睡眠质量低和睡眠不足 5 小时会导致虚弱。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。失眠、睡眠质量低和睡眠不足 5 小时会导致虚弱。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。
