MethodsSong及其同事对160名患有HF的韩国老年人进行了一项横断面观察性研究。在这项研究中，作者研究了维生素D摄入量、睡眠质量和认知功能之间的关系。他们还评估了睡眠质量差是否是缺乏维生素D摄入与老年HF患者认知功能障碍之间关系的介导因素。采用主观测量方法评估维生素D摄入/维生素D缺乏（3天食物日记）、睡眠质量（匹兹堡睡眠质量指数）和认知功能（韩语版简易精神状态检查）。分层回归和中介分析被用来检查协会。1
MethodsSong and colleagues conducted a cross-sectional, observational study with 160 Korean older adults with HF. In the study, the authors examined the relationships between vitamin D intake, sleep quality and cognitive function. They also assessed whether poor sleep quality is a mediator of the association between lack of vitamin D intake and cognitive dysfunction in older adults with HF. Subjective measures were used to evaluate vitamin D intake/vitamin D deficiency (3-day food diary), sleep quality (Pittsburgh Sleep Quality Index) and cognitive function (the Korean version of the Mini-Mental State Examination). Hierarchical regressions and mediation analysis were used to examine the associations. 1
