Abstract：
OBJECTIVE: To verify the association between low self-reported sleep quality (LSQ) and fall in middle-aged and older adults every half-decade of life.
METHODS: A cross-sectional study was conducted using data from the first wave (2015-2016) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is nationally representative. The sample consisted of 8,950 participants who were allocated into eight age groups: 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, and ≥ 85 years. The questionnaires used included self-reported sleep quality and the International Physical Activity Questionnaire short version. Fisher\'s exact test followed by binary logistic regression analysis was performed to identify the odds ratio of sleep quality for fall occurrence, controlled for confounding variables.
RESULTS: Individuals aged 50-105 years (63.6 ± 10.2 years), 57.0% females and 43.0% males, participated in this study. Overall, 21.5% of participants experienced at least one fall. The relative frequency of participants classified as having high or LSQ remained constant across each half-decade of life. The LSQ exhibited a statistically significant OR (p < 0.05) for falls across age groups up to 84, even after accounting for confounding variables.
CONCLUSIONS: LSQ is significantly associated with an increased occurrence of fall in adults aged >50 years, but not for ≥ 85 years regardless of sex and physical activity level.

摘要：
目的：验证自我报告的睡眠质量（LSQ）低与中老年人每五年寿命下降之间的关联。
方法：使用巴西衰老纵向研究（ELSI-Brazil）第一波（2015-2016）的数据进行了横断面研究，具有全国代表性。样本包括8,950名参与者，他们被分为八个年龄组：50-54、55-59、60-64、65-69、70-74、75-79、80-84和≥85岁。使用的问卷包括自我报告的睡眠质量和国际身体活动问卷简短版本。进行Fisher精确检验，然后进行二元逻辑回归分析，以确定跌倒发生的睡眠质量的比值比。控制混杂变量。
结果：50-105岁（63.6±10.2岁）的个人，女性占57.0%，男性占43.0%，参与了这项研究。总的来说,21.5%的参与者经历了至少一次跌倒。被分类为具有高LSQ或LSQ的参与者的相对频率在生命的每五年中保持不变。即使在考虑了混杂变量后，LSQ对于84岁以下年龄组的跌倒仍表现出统计学上的显着OR（p<0.05）。
结论：LSQ与50岁以上成年人跌倒发生率增加显著相关，但无论性别和身体活动水平如何，≥85岁。
