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.
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.
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.
分析性别对老年人失眠、睡眠质量、睡眠时间与虚弱之间关联的影响。
这是一项来自肥胖、肌肉减少症和衰弱与墨西哥老年人队列研究（COSFOMA）的横断面研究。共有 493 名 64-94 岁的老年人参与了该研究。失眠通过雅典失眠量表进行评估，睡眠质量通过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）。衰弱采用 Fried 表型进行操作性定义。此外，还收集了社会人口统计学变量以及身心健康状况。采用逻辑回归模型按性别分层，分析失眠、睡眠质量、睡眠时间与衰弱之间的关系。
参与者包括 299 名（60.7%）女性和 194 名（39.3%）男性。平均年龄为 70.1±5.6 岁。研究样本中 13.4%（n=66）的老年人衰弱，62.5%（n=308）的老年人为衰弱前期，24.1%（n=119）的老年人未衰弱。在调整了社会人口统计学和健康协变量的统计模型中，失眠、睡眠质量差和睡眠时间少于 5 小时与女性脆弱的几率增加有关，但与男性无关。
在老年女性中，存在失眠、睡眠质量差和睡眠时间少于 5 小时可能会增加脆弱的风险。因此，应优先治疗女性的睡眠问题，以避免这种情况的发生。
