缩写说明：COURAGE（欧洲老龄化协作研究，Collaborative Research on Ageing in Europe）；SAGE（世界卫生组织全球老龄化与成人健康研究，WHO Study on global AGEing and adult health）；S. Africa（南非，South Africa）。本研究数据以优势比（Odds Ratio）与95%置信区间（95% Confidence Intervals）形式呈现。所有模型均对模型内纳入的全部慢性病、年龄、性别、受教育程度、财富状况、婚姻状况、饮酒行为、吸烟情况及体力活动水平进行了相互校正；使用全样本构建的模型还额外校正了县域因素。*p、**p、***p分别代表不同显著性水平。本研究采用多变量logistic回归，分析50岁及以上成人中慢性病（自变量）与重度/极重度睡眠问题（因变量）之间的关联。
